Financial Hardship Common With Rheumatologic Disease: How Can Doctors Help?
Many patients struggle with healthcare costs and basic expenses, according to new research.
People with rheumatologic diseases often experience a hidden symptom: financial toxicity or significant economic strain from out-of-pocket costs. A new study of 41,502 patients published in JCR: Journal of Clinical Rheumatology showed that 20% of those with rheumatologic diseases faced financial hardship from medical expenses, with 55% of those unable to pay their bills.
Compared with patients who do not have rheumatologic diseases, and after clinical and sociodemographic factors were controlled for, patients with rheumatologic diseases were:
- 29% more likely to have high levels of financial hardship — difficulty paying; needing to pay over time; or inability to pay bills for doctors, dentists, hospitals, therapists, medication, equipment, nursing homes, or home care.
- 53% more likely to have high levels of financial distress — significant worry about having enough money for retirement, paying medical costs in the event of a serious illness or accident, maintaining their standard of living, paying their usual healthcare costs, and affording their normal monthly bills and housing costs.
- 29% more likely to experience food insecurity, defined as limited or uncertain access to adequate food.
- 58% more likely to report cost-related medication nonadherence — skipping doses, taking less medication, or delaying filling a prescription to save money.
People who were younger than 64 years, male, Black, or uninsured had higher odds of experiencing financial hardship, financial distress, food insecurity, and cost-related medication nonadherence.
This study highlights “just how costly everyday rheumatologic conditions can be for your average American,” said lead study author Troy Amen, MD, MBA, an orthopedic surgery resident at the Hospital for Special Surgery in New York City. These diseases can be disabling, limiting a patient’s ability to work at the very time when expensive medications are needed.
“It’s critical for clinicians to recognize how common the financial burden from healthcare costs can be, and only then can they take steps to better support patients,” said G. Caleb Alexander, MD, MS, professor of epidemiology at Johns Hopkins University in Baltimore, who was not involved in the study.
Here’s how healthcare providers can help.
Consider skipped medication a red flag. It’s often the first sign of a financial concern. “Sometimes with these problems, it looks like simple medication noncompliance, but it’s really a more complex form of nonadherence,” said Susan M. Goodman, MD, professor of clinical medicine at Weill Cornell Medicine in New York City and a coauthor of the study. “And I think if someone’s not taking the medication that had been very helpful, it does behoove the physician to try and figure out why that is.”
Normalize the issue to help patients open up. “I will often say, ‘You know, many, many patients don’t take their medicines exactly as prescribed. About how many days a week do you take this medicine?’” said Dr. Alexander. “If you ask in a nonconfrontational, supportive manner, I’ve found that patients are quite candid.”
Don’t assume insurance has it covered. If patients are uninsured, help them enroll in (or renew) insurance coverage. But don’t assume insurance will solve the whole problem. “There are many people who, although they do have coverage, still can’t afford their medications,” said Dr. Goodman.
For products on high formulary tiers, the patient’s monthly cost can be hundreds to thousands of dollars. “Over the past 10-20 years, we’ve seen remarkable technological innovation in the types of medicines being brought to market, and here, I’m referring primarily to biologics and medicines made from living cells,” said Dr. Alexander, “but many of these have a price tag that is simply astronomical, and insurers aren’t going to bear the brunt of these costs alone.”
Biosimilars can be a bit more affordable, but “the dirty little secret of biosimilars is that they’re not really very much less expensive,” said Dr. Goodman. “If your patient is doing well on a drug that gets dropped from their insurance plan’s formulary, or if they switch to a plan that doesn’t cover it, try calling and advocating for an exception. It’s an uphill battle, but it sometimes works,” she said.
If not? Help your patients apply for a patient assistance program. Many drug manufacturers offer copay assistance through their websites, and nonprofit patient assistance organizations such as the PAN Foundation, the Patient Advocate Foundation’s Co-Pay Relief Program, or The Assistance Fund can also help fill the gaps. One study published in the Journal of Managed Care and Specialty Pharmacy showed that in patients with rheumatoid arthritis, copay assistance was associated with 79% lower odds of prescription abandonment (failure to fill within 30 days of health plan approval).
Beware of “shiny penny syndrome.” It’s easy to get excited about new, innovative medications, especially when sales reps provide plenty of free samples. “There is a tendency to treat every new medicine as if it’s a bright shiny object in the streambed, and you know that’s not always the case,” said Dr. Alexander. “So, I think we have to be careful, especially in settings when we’re talking about ultra–high-cost medicines, that we’re aware of the burden these medicines may place on patients and that we’re navigating that with patients together, and not simply leaving that as a conversation that never happens in the exam room.”
Maybe there’s an older, time-tested drug that works just as well as the newer, more expensive one. Perhaps there is a slightly less effective medicine that costs a lot less. “These are cost–quality trade-offs that clinicians and patients should be navigating together,” said Dr. Alexander. For example, in a patient with rheumatoid arthritis, a tumor necrosis factor alpha inhibitor might work similarly to or almost as well as an interleukin inhibitor, the newer and typically more expensive choice.
“Some clinicians may find it quite unpalatable to be potentially compromising on safety or efficacy in the interest of reducing the cost of therapies, but as former Surgeon General C. Everett Koop said, ‘Drugs don’t work in patients who don’t take them,’ ” said Dr. Alexander. “So, if the choice is for someone not to be taking a treatment, or to be taking one that may be a little bit less good, I’ll take the latter.”
Consider the patient’s broader care team. Encourage patients to discuss costs with their other healthcare providers. For patients taking multiple medications, a few adjustments could make a big impact on their wallets. Primary care providers or other specialists might recommend some older and less expensive, but still effective, drugs, such as thiazides for hypertension or metformin for type 2 diabetes. Another option might be to simplify the patient’s regimen or include some fixed-dose combination pills in place of two others.
And if no one has referred the patient to a medical social worker, make the connection. A social worker can put patients in touch with local agencies that can help them with food, housing, and other nonmedical costs.
Talk about this problem with anyone who will listen. One of the best ways to help patients with rheumatologic diseases is to ensure that decision-makers don’t overlook them. Professional societies such as the American College of Rheumatology can be great resources for advocacy in Washington, DC. Political movements can make drugs more affordable — for example, insulin prices have dropped in recent years because of political pressure, said Dr. Goodman.
“A lot of our national policy now focuses on aiding patients with single high-cost events, but we hope studies like these can really get policymakers to think through how to better support patients with chronic conditions that may have been historically ignored, such as patients with rheumatologic disease,” said Dr. Amen.
The first step is raising awareness and telling your story. “As providers, we are often [at the] forefront in witnessing how chronic conditions and their associated costs can negatively affect patients’ lives and even alter clinical outcomes,” Dr. Amen added. “By publishing data and sharing meaningful patient stories and clinical vignettes, we can begin to advocate and humanize these patients to policymakers.”

Gout Drugs in Late-Phase Trials Might Increase Patients at Target Urate Level
VIENNA — Safe and effective options for lowering serum uric acid (sUA) in patients with gout who are refractory to conventional therapies appear to be near, judging from phase 2 and 3 trials that produced positive results at the annual European Congress of Rheumatology.
Reports from the meeting included two phase 2 studies with novel urate anion transporter 1 (URAT1) inhibitors for patients with refractory gout, in addition to extension data from the phase 3 trial program for SEL-212. In all cases, efficacy appeared to be on the same order of currently available drugs with potentially better tolerability, an important unmet need for patients with gout refractory to traditional therapies.
12-Month Outcomes With SEL-212
The extension data with SEL-212 follow the 6-month results presented from the DISSOLVE I and II trials at EULAR 2023. Now at 12 months, the benefits have proven to be generally sustained with no new safety signals, according to Herbert S.B. Baraf, MD, The Center for Rheumatology and Bone Research, Wheaton, Maryland.
SEL-212 is a drug platform involving two components delivered by intravenous infusion once monthly in sequence. The first, SEL-110, consists of tolerogenic nanoparticles containing sirolimus. The second, SEL-037, is the pegylated uricase pegadricase.
On the 1-month dosing schedule, most patients who had responded at 6 months were still responding at 12 months, and both of the two study doses of SEL-212 in the DISSOLVE trials were well tolerated over the extension, Dr. Baraf reported.
On the basis of the data so far, “this will be an effective and well tolerated therapy for refractory gout over a period of at least 12 months,” Dr. Baraf said.
The DISSOLVE I and II trials were identically designed. Patients with refractory gout, defined as failure to normalize sUA or control symptoms with a xanthine oxidase inhibitor, were randomly assigned to receive 0.15 mg SEL-212, 1.0 mg SEL-212, or placebo.
There was a stopping rule for patients who reached a sUA level < 2 mg/dL 1 hour after the infusion.
The primary endpoint was sUA level < 6 mg/dL for at least 80% of the sixth month of the 6-month trial. About 50% of patients on either dose of SEL-212 met this endpoint (vs 4% of those receiving placebo; P < .0001). There was a numerical advantage for the higher dose in both studies.
Patients who completed the 6-month trial were eligible for a 6-month extension, during which they remained on their assigned therapy, including placebo. This phase was also blinded. Patients who met the stopping rule in either the main study or extension did not take the study drug but remained in the study for final analysis.
Of the 265 patients who participated in the main phase of the study, 143 (54%) completed the 6-month extension. Most discontinuations were the result of the stopping rule. Reasons for other patients discontinuing the study included withdrawal of consent in about 10% of each treatment arm and adverse events in 13.8%, 6.8%, and 2.2% of the high-dose, low-dose, and placebo groups, respectively.
At 12 months, when the data from the two trials were pooled, the proportion of patients on therapy and responding remained at about 50% in the high-dose group and 43% in the low-dose group on an intention-to-treat analysis. Relative to the 8% response rate for placebo, the advantage for either dose was highly significant (P < .0001).
In the subgroup of patients with tophi at baseline, representing about half the study group, responses were low at 12 months, whether on high- (41%) or low-dose (43%) SEL-212. The rate of response among placebo patients with baseline tophi was 9%.
Safety of SEL-212
The safety over the 6-month extension did not differ substantially from that observed during the first 6 months, according to Dr. Baraf. This was reiterated in more detail by Alan Kivitz, MD, Altoona Center for Clinical Research, Duncansville, Pennsylvania. He delivered a separate safety presentation focused on DISSOLVE I.
Specifically, there were no serious adverse events thought to be related to treatment. Besides gout flares, which affected approximately 27% of patients regardless of active treatment or placebo assignment, the most common adverse effect was hypertriglyceridemia, which was observed in 5.4% of patients on active treatment vs 0% of those receiving placebo. Independent of the treatment arm, less than 5% of patients developed stomatitis or cellulitis during the 6-month extension period.
In the 6-month extension phase, there were no infusion reactions observed within 1 hour after SEL-212 administration and just two overall that occurred with low-dose SEL-212, according to Kivitz.
New Selective URAT1 Inhibitors
The other potential advance in the treatment of refractory gout is coming from newer selective URAT1 inhibitors. According to the lead investigators of two phase 2 trials evaluating a novel URAT1 inhibitor, the urate transporter protein has long been considered the most promising target for gout treatment. As this protein regulates the absorption of uric acid from the renal tubule, it has a direct uric acid–lowering effect. However, the adverse events of current agents, such as probenecid, benzbromarone, and sulfinpyrazone, have created a need for drugs with a better benefit-to-risk ratio.
In one of two multicenter phase 2 studies on refractory gout, the experimental agent ruzinurad was tested as an adjunct to the xanthine oxidase inhibitor febuxostat. In the other, the objective was to evaluate whether the experimental agent AR882 or AR882 plus allopurinol is better than allopurinol alone for reducing tophi at 12 months.
Ruzinurad Plus Febuxostat
In the ruzinurad trial, 151 patients with symptomatic gout and elevated sUA (> 6 mg/dL) for at least 6 weeks on stable doses of febuxostat were randomized to receive 5 mg ruzinurad, 10 mg ruzinurad, or placebo. All remained on febuxostat. In the active treatment arms, the starting ruzinurad dose was 1 mg before titrating up to the assigned target.
For the primary endpoint of sUA < 6 mg/dL at 12 weeks, the rates were 56.9%, 53.1%, and 13.7% in the high-dose, low-dose, and placebo groups, respectively (P < .0001 for both ruzinurad arms), reported Huihua Ding, MD, a clinician and researcher at Shanghai Jiao Tong University, Shanghai, China.
“Consistently, subgroup analyses based on baseline eGFR [estimated glomerular filtration rate], sUA, and tophus demonstrated superior effective of ruzinurad plus febuxostat over placebo plus febuxostat,” reported Dr. Ding, who noted that previous clinical studies suggested the potential for synergism between ruzinurad and febuxostat.
The proportion of patients achieving the more rigorous target of < 0.5 mg/dL was also higher with the higher and lower doses of ruzinurad vs placebo (43.1% and 38.8% vs 9.8%, respectively).
The proportion of patients with treatment-emergent side effects did not differ between the three groups. The most common were gout flares, which were observed in 39.2%, 49.0%, and 45.1% in the high-dose, low-dose, and placebo groups, respectively. Most adverse events were mild or moderate, and none led to treatment discontinuation.
The favorable benefit-to-risk profile of ruzinurad was attributed by Dr. Ding to its high relative selectivity and potent inhibition of URAT1, an advantage that might be relevant to avoiding side effects at higher doses.
AR882 in Patients With Tophi
In the trial with AR882, 42 patients with refractory gout and at least one subcutaneous tophus were randomized to receive 75 mg AR882, 50 mg AR882 plus allopurinol, or allopurinol alone. All drugs were taken once daily. Doses of allopurinol of up to 300 mg were permitted.
The changes in the target tophus area and crystal volume at month 6 were compared, and patients who completed this phase were invited into a 6-month extension. In the 6-month extension, 75 mg AR882 was additionally provided to those who had been in the single-agent allopurinol arm. The other arms were unchanged.
Tophi measurements were performed with calipers at regular intervals. Change from baseline in sUA levels was also an efficacy measure, according to Robert Keenan, MD, chief medical officer of Arthrosi Therapeutics, which is developing AR882.
From average baseline sUA levels of > 9 mg/dL, all three treatments reduced sUA levels by an average of at least 4.5 mg by month 3. At month 6, complete resolution of at least one target tophus was observed in 29% of the group randomized to receive 75 mg AR882 alone, 8% of those randomized to receive 50 mg AR882 plus allopurinol, and 8% of those on allopurinol alone.
At month 12, the average sUA levels were 4.3 mg/dL for 75 mg AR882, 3.7 mg/dL for 50 mg AR882 plus allopurinol, and 2.9 mg/dL for the 75 mg AR882 plus allopurinol extension-switch arm.
At the 12-month mark, the proportions of patients with complete resolution of any tophus were 50.0% for 75 mg AR882, 12.5% for 50 mg AR882 plus allopurinol, and 36.4% for the 75 mg AR882 plus allopurinol extension-switch arm, according to Dr. Keenan.
Compared with allopurinol alone at 6 months, 75 mg AR882 led to a reduction in total urate crystal volume, and this reduction was sustained at 12 months, he added.
Alone or in combination with allopurinol, AR882 was well tolerated. Gout flares were the most common adverse events, but they declined with continued AR882 treatment, according to Dr. Keenan. Diarrhea, headache, and upper respiratory infections were reported but were of mild or moderate severity.
Again, the take-home message from this study, like the other phase 2 study of a novel URAT1 inhibitor, is that these newer drugs might offer a better benefit-to-risk ratio, particularly in those with refractory disease.

VIENNA — Safe and effective options for lowering serum uric acid (sUA) in patients with gout who are refractory to conventional therapies appear to be near, judging from phase 2 and 3 trials that produced positive results at the annual European Congress of Rheumatology.
Reports from the meeting included two phase 2 studies with novel urate anion transporter 1 (URAT1) inhibitors for patients with refractory gout, in addition to extension data from the phase 3 trial program for SEL-212. In all cases, efficacy appeared to be on the same order of currently available drugs with potentially better tolerability, an important unmet need for patients with gout refractory to traditional therapies.
12-Month Outcomes With SEL-212
The extension data with SEL-212 follow the 6-month results presented from the DISSOLVE I and II trials at EULAR 2023. Now at 12 months, the benefits have proven to be generally sustained with no new safety signals, according to Herbert S.B. Baraf, MD, The Center for Rheumatology and Bone Research, Wheaton, Maryland.
SEL-212 is a drug platform involving two components delivered by intravenous infusion once monthly in sequence. The first, SEL-110, consists of tolerogenic nanoparticles containing sirolimus. The second, SEL-037, is the pegylated uricase pegadricase.
On the 1-month dosing schedule, most patients who had responded at 6 months were still responding at 12 months, and both of the two study doses of SEL-212 in the DISSOLVE trials were well tolerated over the extension, Dr. Baraf reported.
On the basis of the data so far, “this will be an effective and well tolerated therapy for refractory gout over a period of at least 12 months,” Dr. Baraf said.
The DISSOLVE I and II trials were identically designed. Patients with refractory gout, defined as failure to normalize sUA or control symptoms with a xanthine oxidase inhibitor, were randomly assigned to receive 0.15 mg SEL-212, 1.0 mg SEL-212, or placebo.
There was a stopping rule for patients who reached a sUA level < 2 mg/dL 1 hour after the infusion.
The primary endpoint was sUA level < 6 mg/dL for at least 80% of the sixth month of the 6-month trial. About 50% of patients on either dose of SEL-212 met this endpoint (vs 4% of those receiving placebo; P < .0001). There was a numerical advantage for the higher dose in both studies.
Patients who completed the 6-month trial were eligible for a 6-month extension, during which they remained on their assigned therapy, including placebo. This phase was also blinded. Patients who met the stopping rule in either the main study or extension did not take the study drug but remained in the study for final analysis.
Of the 265 patients who participated in the main phase of the study, 143 (54%) completed the 6-month extension. Most discontinuations were the result of the stopping rule. Reasons for other patients discontinuing the study included withdrawal of consent in about 10% of each treatment arm and adverse events in 13.8%, 6.8%, and 2.2% of the high-dose, low-dose, and placebo groups, respectively.
At 12 months, when the data from the two trials were pooled, the proportion of patients on therapy and responding remained at about 50% in the high-dose group and 43% in the low-dose group on an intention-to-treat analysis. Relative to the 8% response rate for placebo, the advantage for either dose was highly significant (P < .0001).
In the subgroup of patients with tophi at baseline, representing about half the study group, responses were low at 12 months, whether on high- (41%) or low-dose (43%) SEL-212. The rate of response among placebo patients with baseline tophi was 9%.
Safety of SEL-212
The safety over the 6-month extension did not differ substantially from that observed during the first 6 months, according to Dr. Baraf. This was reiterated in more detail by Alan Kivitz, MD, Altoona Center for Clinical Research, Duncansville, Pennsylvania. He delivered a separate safety presentation focused on DISSOLVE I.
Specifically, there were no serious adverse events thought to be related to treatment. Besides gout flares, which affected approximately 27% of patients regardless of active treatment or placebo assignment, the most common adverse effect was hypertriglyceridemia, which was observed in 5.4% of patients on active treatment vs 0% of those receiving placebo. Independent of the treatment arm, less than 5% of patients developed stomatitis or cellulitis during the 6-month extension period.
In the 6-month extension phase, there were no infusion reactions observed within 1 hour after SEL-212 administration and just two overall that occurred with low-dose SEL-212, according to Kivitz.
New Selective URAT1 Inhibitors
The other potential advance in the treatment of refractory gout is coming from newer selective URAT1 inhibitors. According to the lead investigators of two phase 2 trials evaluating a novel URAT1 inhibitor, the urate transporter protein has long been considered the most promising target for gout treatment. As this protein regulates the absorption of uric acid from the renal tubule, it has a direct uric acid–lowering effect. However, the adverse events of current agents, such as probenecid, benzbromarone, and sulfinpyrazone, have created a need for drugs with a better benefit-to-risk ratio.
In one of two multicenter phase 2 studies on refractory gout, the experimental agent ruzinurad was tested as an adjunct to the xanthine oxidase inhibitor febuxostat. In the other, the objective was to evaluate whether the experimental agent AR882 or AR882 plus allopurinol is better than allopurinol alone for reducing tophi at 12 months.
Ruzinurad Plus Febuxostat
In the ruzinurad trial, 151 patients with symptomatic gout and elevated sUA (> 6 mg/dL) for at least 6 weeks on stable doses of febuxostat were randomized to receive 5 mg ruzinurad, 10 mg ruzinurad, or placebo. All remained on febuxostat. In the active treatment arms, the starting ruzinurad dose was 1 mg before titrating up to the assigned target.
For the primary endpoint of sUA < 6 mg/dL at 12 weeks, the rates were 56.9%, 53.1%, and 13.7% in the high-dose, low-dose, and placebo groups, respectively (P < .0001 for both ruzinurad arms), reported Huihua Ding, MD, a clinician and researcher at Shanghai Jiao Tong University, Shanghai, China.
“Consistently, subgroup analyses based on baseline eGFR [estimated glomerular filtration rate], sUA, and tophus demonstrated superior effective of ruzinurad plus febuxostat over placebo plus febuxostat,” reported Dr. Ding, who noted that previous clinical studies suggested the potential for synergism between ruzinurad and febuxostat.
The proportion of patients achieving the more rigorous target of < 0.5 mg/dL was also higher with the higher and lower doses of ruzinurad vs placebo (43.1% and 38.8% vs 9.8%, respectively).
The proportion of patients with treatment-emergent side effects did not differ between the three groups. The most common were gout flares, which were observed in 39.2%, 49.0%, and 45.1% in the high-dose, low-dose, and placebo groups, respectively. Most adverse events were mild or moderate, and none led to treatment discontinuation.
The favorable benefit-to-risk profile of ruzinurad was attributed by Dr. Ding to its high relative selectivity and potent inhibition of URAT1, an advantage that might be relevant to avoiding side effects at higher doses.
AR882 in Patients With Tophi
In the trial with AR882, 42 patients with refractory gout and at least one subcutaneous tophus were randomized to receive 75 mg AR882, 50 mg AR882 plus allopurinol, or allopurinol alone. All drugs were taken once daily. Doses of allopurinol of up to 300 mg were permitted.
The changes in the target tophus area and crystal volume at month 6 were compared, and patients who completed this phase were invited into a 6-month extension. In the 6-month extension, 75 mg AR882 was additionally provided to those who had been in the single-agent allopurinol arm. The other arms were unchanged.
Tophi measurements were performed with calipers at regular intervals. Change from baseline in sUA levels was also an efficacy measure, according to Robert Keenan, MD, chief medical officer of Arthrosi Therapeutics, which is developing AR882.
From average baseline sUA levels of > 9 mg/dL, all three treatments reduced sUA levels by an average of at least 4.5 mg by month 3. At month 6, complete resolution of at least one target tophus was observed in 29% of the group randomized to receive 75 mg AR882 alone, 8% of those randomized to receive 50 mg AR882 plus allopurinol, and 8% of those on allopurinol alone.
At month 12, the average sUA levels were 4.3 mg/dL for 75 mg AR882, 3.7 mg/dL for 50 mg AR882 plus allopurinol, and 2.9 mg/dL for the 75 mg AR882 plus allopurinol extension-switch arm.
At the 12-month mark, the proportions of patients with complete resolution of any tophus were 50.0% for 75 mg AR882, 12.5% for 50 mg AR882 plus allopurinol, and 36.4% for the 75 mg AR882 plus allopurinol extension-switch arm, according to Dr. Keenan.
Compared with allopurinol alone at 6 months, 75 mg AR882 led to a reduction in total urate crystal volume, and this reduction was sustained at 12 months, he added.
Alone or in combination with allopurinol, AR882 was well tolerated. Gout flares were the most common adverse events, but they declined with continued AR882 treatment, according to Dr. Keenan. Diarrhea, headache, and upper respiratory infections were reported but were of mild or moderate severity.
Again, the take-home message from this study, like the other phase 2 study of a novel URAT1 inhibitor, is that these newer drugs might offer a better benefit-to-risk ratio, particularly in those with refractory disease.
“AR882 may offer improved efficacy and better safety compared to existing therapies in the treatment of patients with gout, including those with both clinically visible and subclinical crystal deposition,” Dr. Keenan said.

FROM EULAR 2024
Nurse-Led Care for Gout Generates Best Uric Acid Control
VIENNA — To maintain gout in remission, nurses in a rheumatology service do better than doctors in implementing a straightforward treat-to-target (T2T) strategy, according to a randomized study that showed a consistent advantage across subgroups.
“Our study provides evidence that nurse-led therapy for gout leads to better uric acid control, which is an important consideration with the increasing incidence and the increasing costs of managing this condition,” said Jesper W. Larsen, a registered nurse affiliated with the Department of Rheumatology at North Denmark Regional Hospital, Hjørring, Denmark. He presented the study at the annual European Congress of Rheumatology.
The advantage of nurse-led care was seen across every subgroup evaluated. Moreover, more patients in the nurse-led group than in the usual care group remained on urate-lowering therapy at the end of the 2-year study.
The optimal management of gout is based on the treatment goal of lowering serum uric acid (sUA) to below the physiologic level of 0.36 mmol/L (6 mg/dL), a strategy called T2T that is endorsed by both EULAR and the American College of Rheumatology.
“This target can be reached in most patients with commonly used therapies, including allopurinol, which is relatively inexpensive,” Mr. Larsen said. Given that disease control and sustained remission are largely based on this target, he and his colleagues tested the hypothesis that nurses working in a rheumatology service could provide efficient and cost-effective care.
A total of 286 patients with gout defined by microscopy who were treated between 2015 and 2021 were enrolled in the study. Of these, 100 patients who had been enrolled before the introduction of nurse-led care received and were maintained on usual care, which generally included diagnosis by an orthopedist, an emergency room physician, or an internist, with subsequent treatment and follow-up with a general practitioner.
Of 186 patients treated after nurse-led care was implemented, 72 were transitioned to usual care, and the remaining 114 continued receiving nurse-led care over the next 2 years of follow-up. In the nurse-led care arm, nurses who specialized in rheumatology and were trained in gout management monitored a structured T2T strategy. They were available for consultation, provided patient education, and followed laboratory values, including sUA, which they used to adjust treatments.
Except in the case of complications, “there was no more contact with physicians” once care was transferred to the nurse, Mr. Larsen said. Most of the nurse management was based on sUA laboratory values and performed by telephone.
At 2 years, 112 patients in the nurse-led care group were compared with the 144 in the usual care group. Two of the 114 patients who entered the nurse-care cohort and 28 of the 172 in the usual care cohort died before the study ended.
(83% vs 44%). This was also true of patients aged 70 years or older (84% vs 45%), patients with tophi (60% vs 33%), and patients with sUA > 0.5 mmol/L at baseline (84% vs 44%). Nurse-led care also kept a greater proportion of patients at target who entered the study with an estimated glomerular filtration rate < 60 mL/min per 1.73 m2 (84% vs 52%) or were taking diuretics (89% vs 52%). All differences reached statistical significance (P < .05).
The reason for the lower mortality at 2 years in the nurse-led group (4% vs 23%; P < .001) is unclear, according to Mr. Larsen. In addition to considering a selection bias that might have channeled patients with more severe disease to usual care, he and his coinvestigators are also considering whether the lower rates of sUA control in the usual care group might have led to a higher rate of cardiovascular events.
Because of some baseline imbalances, a selection bias cannot be ruled out, but the imbalances did not uniformly favor nurse-led care. For example, the proportion of patients with diabetes (23% vs 13%) or a baseline cancer diagnosis (11% vs 5%) was higher in the nurse-led care group. The proportion of patients with atrial fibrillation (45% vs 35%) or on diuretics (47% vs 33%) at baseline was higher in the usual care group.
The median age of 69 years was the same in the two groups, although the nurse-led group included a higher proportion of men to women (86% vs 76%).
Within a T2T strategy, nurses focused on reaching the target might do a better job than physicians in consistently monitoring and adjusting therapies as needed, but Mr. Larsen also speculated that nurses might offer a more collaborative approach and provide greater support through patient education and regular telephone contact.
Potential Advantages of Nurse-Led Care
Clinicians concerned about nurses missing nuances in disease progression or being slow to recognize complications might be surprised to learn about the advantage of nurse-led care, but Mwidimi Ndosi, PhD, an associate professor in rheumatology nursing at the University of the West of England, Bristol, England, was not.
“There is quite a large literature to show that nursing care is often superior to physician-led patient management in the appropriate circumstances,” Mr. Ndosi said. In this specific instance of gout management, he said that the treatment target is clear, and nurses are often able to devote more time to a specific goal, like T2T, than clinicians balancing more priorities.
“In this trial, the care was administered by nurse specialists who presumably are skilled in this disease and know their limitations if a consultation with a physician is needed,” he said.
Mr. Ndosi, like Mr. Larsen, considers it likely that nurse-led programs for a T2T gout protocol will be implemented elsewhere. Mr. Ndosi pointed out that patients who are concerned about the quality of nurse-led care are generally convinced of its merits over time.
Because of factors such as nurses’ ability to spend more clinical time with patients and greater willingness to engage in resolving obstacles to self-care, compared with physicians, “there are many studies to show that patients are often more satisfied with care provided by nurses,” he said.
Mr. Larsen and Mr. Ndosi reported no potential conflicts of interest.

For example, the proportion of patients with diabetes (23% vs 13%) or a baseline cancer diagnosis (11% vs 5%) was higher in the nurse-led care group. The proportion of patients with atrial fibrillation (45% vs 35%) or on diuretics (47% vs 33%) at baseline was higher in the usual care group.
The median age of 69 years was the same in the two groups, although the nurse-led group included a higher proportion of men to women (86% vs 76%).
Within a T2T strategy, nurses focused on reaching the target might do a better job than physicians in consistently monitoring and adjusting therapies as needed, but Mr. Larsen also speculated that nurses might offer a more collaborative approach and provide greater support through patient education and regular telephone contact.
Potential Advantages of Nurse-Led Care
Clinicians concerned about nurses missing nuances in disease progression or being slow to recognize complications might be surprised to learn about the advantage of nurse-led care, but Mwidimi Ndosi, PhD, an associate professor in rheumatology nursing at the University of the West of England, Bristol, England, was not.
“There is quite a large literature to show that nursing care is often superior to physician-led patient management in the appropriate circumstances,” Mr. Ndosi said. In this specific instance of gout management, he said that the treatment target is clear, and nurses are often able to devote more time to a specific goal, like T2T, than clinicians balancing more priorities.
“In this trial, the care was administered by nurse specialists who presumably are skilled in this disease and know their limitations if a consultation with a physician is needed,” he said.
Mr. Ndosi, like Mr. Larsen, considers it likely that nurse-led programs for a T2T gout protocol will be implemented elsewhere. Mr. Ndosi pointed out that patients who are concerned about the quality of nurse-led care are generally convinced of its merits over time.
Because of factors such as nurses’ ability to spend more clinical time with patients and greater willingness to engage in resolving obstacles to self-care, compared with physicians, “there are many studies to show that patients are often more satisfied with care provided by nurses,” he said.
Mr. Larsen and Mr. Ndosi reported no potential conflicts of interest.

VIENNA — To maintain gout in remission, nurses in a rheumatology service do better than doctors in implementing a straightforward treat-to-target (T2T) strategy, according to a randomized study that showed a consistent advantage across subgroups.
“Our study provides evidence that nurse-led therapy for gout leads to better uric acid control, which is an important consideration with the increasing incidence and the increasing costs of managing this condition,” said Jesper W. Larsen, a registered nurse affiliated with the Department of Rheumatology at North Denmark Regional Hospital, Hjørring, Denmark. He presented the study at the annual European Congress of Rheumatology.
The advantage of nurse-led care was seen across every subgroup evaluated. Moreover, more patients in the nurse-led group than in the usual care group remained on urate-lowering therapy at the end of the 2-year study.
The optimal management of gout is based on the treatment goal of lowering serum uric acid (sUA) to below the physiologic level of 0.36 mmol/L (6 mg/dL), a strategy called T2T that is endorsed by both EULAR and the American College of Rheumatology.
“This target can be reached in most patients with commonly used therapies, including allopurinol, which is relatively inexpensive,” Mr. Larsen said. Given that disease control and sustained remission are largely based on this target, he and his colleagues tested the hypothesis that nurses working in a rheumatology service could provide efficient and cost-effective care.
A total of 286 patients with gout defined by microscopy who were treated between 2015 and 2021 were enrolled in the study. Of these, 100 patients who had been enrolled before the introduction of nurse-led care received and were maintained on usual care, which generally included diagnosis by an orthopedist, an emergency room physician, or an internist, with subsequent treatment and follow-up with a general practitioner.
Of 186 patients treated after nurse-led care was implemented, 72 were transitioned to usual care, and the remaining 114 continued receiving nurse-led care over the next 2 years of follow-up. In the nurse-led care arm, nurses who specialized in rheumatology and were trained in gout management monitored a structured T2T strategy. They were available for consultation, provided patient education, and followed laboratory values, including sUA, which they used to adjust treatments.
Except in the case of complications, “there was no more contact with physicians” once care was transferred to the nurse, Mr. Larsen said. Most of the nurse management was based on sUA laboratory values and performed by telephone.
At 2 years, 112 patients in the nurse-led care group were compared with the 144 in the usual care group. Two of the 114 patients who entered the nurse-care cohort and 28 of the 172 in the usual care cohort died before the study ended.
(83% vs 44%). This was also true of patients aged 70 years or older (84% vs 45%), patients with tophi (60% vs 33%), and patients with sUA > 0.5 mmol/L at baseline (84% vs 44%). Nurse-led care also kept a greater proportion of patients at target who entered the study with an estimated glomerular filtration rate < 60 mL/min per 1.73 m2 (84% vs 52%) or were taking diuretics (89% vs 52%). All differences reached statistical significance (P < .05).
The reason for the lower mortality at 2 years in the nurse-led group (4% vs 23%; P < .001) is unclear, according to Mr. Larsen. In addition to considering a selection bias that might have channeled patients with more severe disease to usual care, he and his coinvestigators are also considering whether the lower rates of sUA control in the usual care group might have led to a higher rate of cardiovascular events.
Because of some baseline imbalances, a selection bias cannot be ruled out, but the imbalances did not uniformly favor nurse-led care. For example, the proportion of patients with diabetes (23% vs 13%) or a baseline cancer diagnosis (11% vs 5%) was higher in the nurse-led care group.

Trial Confirms Treating Gout Based on Uric Acid Level, Not Symptoms
UPDATED July 8, 2024 // Editor's note: This article has been revised to give a more nuanced view from Yael Klionsky, MD, about the need for more accurate and consistent gout management guidelines for busy primary care clinicians who often rely on them in clinical practice.
VIENNA — The first multicenter randomized trial in gout to compare treat-to-target (T2T) and treat for symptom avoidance (T2S) strategies has finally generated data to make the guideline-recommended practice of T2T evidence-based.
The T2T strategy may be guideline-endorsed, but it has never been validated, contended Anusha Moses, MSc, a researcher and PhD candidate at the University of Twente, Enschede, the Netherlands. She argued that this controlled trial fills an evidence gap.
T2T is defined as maintaining a serum uric acid (sUA) level below the physiologic threshold level of 36 mmol/L (< 6 mg/dL). T2S, in contrast, is a strategy of symptom control, typically basing therapy on suppression of symptoms independent of sUA, Dr. Moses explained.
Both the American College of Rheumatology and European Alliance of Associations for Rheumatology (EULAR) have already endorsed T2T, but other organizations, such as the American College of Physicians (ACP), still accept symptom-based treatment in its gout clinical practice guideline, according to Dr. Moses.
The results of the trial were not surprising based on the pathophysiology of gout. Elevated sUA is considered the driver of both flares and the complications of gout. This well-established association led to endorsement of T2T in guidelines from organizations such as EULAR, but Dr. Moses said a controlled trial allows this to be declared as evidence based.
To provide proof that T2T is superior, 308 gout patients at eight centers were randomized to one of the two strategies in a trial called GO TEST OVERTURE. In the T2T arm, commonly used therapies, such as allopurinol, benzbromarone, and febuxostat were employed to achieve and maintain a target sUA of < 0.36 mmol/L. In the T2S comparator arm, the same drugs were offered to control symptoms and prevent recurrences, but sUA levels were not used to guide treatment.
The 1-year results of a planned 2-year study were presented in an oral abstract session at the annual European Congress of Rheumatology. For this analysis, outcomes were compared in the last 6 months prior to the 1-year data analysis. When assessed at 2 years, the comparison will again be made in the prior 6 months of the study.
For the primary endpoint of flares defined by the validated Gallo criteria, the mean rates were 1.3 for T2T and 1.85 for T2S (P < .001), Dr. Moses reported.
The reduced risk for flares correlated with the greater proportion of patients with sUA < 0.36 mmol/L. These proportions were 72% and 26% (P < .001) for the T2T and T2S groups, respectively. The mean sUA levels were 0.31 mmol/L and 0.42 mmol/L (P < .001), respectively.
At the 1-year mark, none of the secondary endpoints reached statistical significance. These included mean numeric rating pain scale (2.46 vs 2.41), the proportion of patients in remission (8% vs 5.7%), and the mean Health Assessment Questionnaire-Disability Index score (0.65 vs 0.62), according to Dr. Moses, who said all of these endpoints will continue to be followed in the planned second year of the study.
At baseline, there were no differences in any of the variables evaluated, including age (about 62.5 years in both groups), proportion of patients with a body mass index > 30 kg/m2 (about 62%), sUA (about 0.5 mmol/L), or estimated glomerular filtration rate (about 70 mL/min/1.73 m2).
Nonspecialists Should Heed the Results
According to Yael Klionsky, MD, a clinical assistant professor of rheumatology and immunology at Wake Forest University School of Medicine, Winston-Salem, North Carolina, these data are not a surprise.
Even before this trial was completed, the message for clinicians is that they “should be focused on maintaining serum uric acid levels below physiological levels to improve outcomes” in patients with recurrent flares, said Klionsky, citing the validated EULAR and ACR guidelines.
While the ACP does still consider T2S acceptable as a strategy for chronic gout management, Klionsky pointed out that those guidelines have not been updated recently. Specialists in the treatment of gout do not need any more evidence that the T2T approach leads to better outcomes.
However, she agreed with the principle that non-rheumatologists need to be reached with better guidance in regard to gout management. While she expects the ACP to endorse T2T the next time their guidelines are updated, she hopes that primary care physicians recognize that T2T should now be a standard.
“In a 10- to 20-minute visit, managing multiple chronic conditions can be a challenge in primary care,” Klionsky said. “Many clinicians rely on guidelines so it is important to have consistent and accurate information.”
There is currently some distance between specialists and primary care physicians regarding the goals of gout management, according to a study that Klionsky presented at EULAR 2024. In a survey, nonspecialists and specialists did not perceive treatment priorities in the same way.
In this survey, which elicited responses from 151 rheumatologists, 150 nephrologists, and 102 primary care physicians, there was general agreement that preventing flares is a priority, but only 30% of primary care physicians and 35% of nephrologists vs 64% of rheumatologists identified the T2T target of < 0.36 mmol/L as a key step in reaching this goal.
Conversely, 58% of primary care physicians and 42% of nephrologists vs only 34% of rheumatologists considered absence of gout pain to be in the top three criteria.
In addition to the fact that primary care physicians differ from specialists in their goals for gout treatment, these data “highlight the need for the importance of a standardized definition of gout remission that includes serum uric acid control,” Dr. Klionsky said. She further thinks that this type of guidance should be disseminated to nonspecialists.
Dr. Moses reported no potential conflicts of interest. Dr. Klionsky reported financial relationships with Amgen, AstraZeneca, Eli Lilly, and MedIQ.

Colchicine: A New Tool for Ischemic Stroke, CVD Event Recurrence?
BASEL, SWITZERLAND — However, the results did reveal a significant reduction in recurrent stroke and cardiovascular events in the per-protocol analysis and in the subgroup of patients with coronary artery disease.
“Although the primary endpoint was neutral, the CONVINCE results support the hypothesis that long-term anti-inflammatory therapy with colchicine may reduce recurrent stroke and cardiovascular events, specifically in stroke patients with atherosclerosis,” lead investigator Peter Kelly, MD, University College Dublin School of Medicine, Dublin, Ireland, concluded.
The results were presented at the European Stroke Organization Conference (ESOC) 2024.
Inflammation, Dr. Kelly said, plays an important role in the pathophysiology of atherosclerotic plaque, a major cause of cardiovascular events and ischemic strokes.
Colchicine, an established, widely available, low-cost drug that reduces inflammatory response, has been shown to reduce recurrent vascular events in patients with coronary artery disease.
The CONVINCE trial was conducted to see whether colchicine could show similar benefits in patients with non-severe, non-cardioembolic stroke or transient ischemic attack.
Conducted in 16 European countries and Canada, the CONVINCE trial included 3154 patients with a recent non-cardioembolic nondisabling ischemic stroke or high-risk transient ischemic attack. They were randomly assigned to receive colchicine (0.5 mg/d) or placebo.
Key exclusion criteria included evidence of atrial fibrillation or other source of cardioembolism, a defined cause of stroke other than atherosclerosis or small vessel disease, a glomerular filtration rate below 50 mL/min, and the use of drugs that interact with colchicine.
The primary endpoint was a composite of first recurrent ischemic stroke, myocardial infarction, cardiac arrest, or hospitalization for unstable angina. Study participants were followed-up over 36 months.
Results of the primary intention-to-treat analysis showed that the primary endpoint occurred in 153 patients randomized to low-dose colchicine (9.8%) versus 185 in the placebo group (11.8%). This translated into a hazard ratio (HR) of 0.84 (95% CI, 0.68-1.05; P = .12) — a nonsignificant result.
Reduced levels of C-reactive protein in the colchicine group showed the anti-inflammatory effect of treatment with colchicine, Dr. Kelly reported.
In a prespecified on-treatment analysis (excluding patients with major protocol violations), colchicine did show a significant benefit in the primary endpoint (HR, 0.80; 95% CI, 0.63-0.99).
A Novel Target for Stroke Treatment
In addition, significantly reduced rates of recurrent stroke or cardiovascular events were observed in the subgroup of patients with a history of coronary artery disease.
In an updated meta-analysis of existing colchicine studies including CONVINCE, there was a significant reduction in the risk for ischemic stroke (risk ratio, 0.73; 95% CI, 0.58-0.90).
“The signals of benefit of colchicine in secondary analyses are in line with findings from previous trials and indicate the potential of colchicine in prevention after stroke,” Dr. Kelly said.
He pointed out that the COVID pandemic reduced the planned follow-up time in the CONVINCE trial, which led to the study being underpowered for the primary analysis.
“Further trials are needed in all stroke subtypes, but with particular focus on patients with objective evidence of atherosclerosis,” he said.
Commenting on the findings, Mira Katan, MD, University Hospital of Basel, Switzerland, noted that inflammation represents a novel target for stroke treatment.
“We have never before looked at treating inflammation in stroke. Although the primary endpoint was not reached in the CONVINCE study, the on-treatment analysis and meta-analysis showed a risk reduction, and we know colchicine works in cardiology. I think this is a fantastic trial, giving us a new target for stroke therapy,” Dr. Katan said.
“I think we have a new tool, but of course we need further trials to confirm that,” she added.
The CONVINCE trial was supported by Health Research Board Ireland, Deutsche Forschungsgesellschaft, Fonds Wetenschappelijk Onderzoek (FWO), and the Irish Heart Foundation. Dr. Kelly received funding from the Irish Heart Foundation. Dr. Katan reported no relevant disclosures.

In a prespecified on-treatment analysis (excluding patients with major protocol violations), colchicine did show a significant benefit in the primary endpoint (HR, 0.80; 95% CI, 0.63-0.99).
A Novel Target for Stroke Treatment
In addition, significantly reduced rates of recurrent stroke or cardiovascular events were observed in the subgroup of patients with a history of coronary artery disease.
In an updated meta-analysis of existing colchicine studies including CONVINCE, there was a significant reduction in the risk for ischemic stroke (risk ratio, 0.73; 95% CI, 0.58-0.90).
“The signals of benefit of colchicine in secondary analyses are in line with findings from previous trials and indicate the potential of colchicine in prevention after stroke,” Dr. Kelly said.
He pointed out that the COVID pandemic reduced the planned follow-up time in the CONVINCE trial, which led to the study being underpowered for the primary analysis.
“Further trials are needed in all stroke subtypes, but with particular focus on patients with objective evidence of atherosclerosis,” he said.
Commenting on the findings, Mira Katan, MD, University Hospital of Basel, Switzerland, noted that inflammation represents a novel target for stroke treatment.
“We have never before looked at treating inflammation in stroke. Although the primary endpoint was not reached in the CONVINCE study, the on-treatment analysis and meta-analysis showed a risk reduction, and we know colchicine works in cardiology. I think this is a fantastic trial, giving us a new target for stroke therapy,” Dr. Katan said.
“I think we have a new tool, but of course we need further trials to confirm that,” she added.
The CONVINCE trial was supported by Health Research Board Ireland, Deutsche Forschungsgesellschaft, Fonds Wetenschappelijk Onderzoek (FWO), and the Irish Heart Foundation. Dr. Kelly received funding from the Irish Heart Foundation. Dr. Katan reported no relevant disclosures.

BASEL, SWITZERLAND — However, the results did reveal a significant reduction in recurrent stroke and cardiovascular events in the per-protocol analysis and in the subgroup of patients with coronary artery disease.
“Although the primary endpoint was neutral, the CONVINCE results support the hypothesis that long-term anti-inflammatory therapy with colchicine may reduce recurrent stroke and cardiovascular events, specifically in stroke patients with atherosclerosis,” lead investigator Peter Kelly, MD, University College Dublin School of Medicine, Dublin, Ireland, concluded.
The results were presented at the European Stroke Organization Conference (ESOC) 2024.
Inflammation, Dr. Kelly said, plays an important role in the pathophysiology of atherosclerotic plaque, a major cause of cardiovascular events and ischemic strokes.
Colchicine, an established, widely available, low-cost drug that reduces inflammatory response, has been shown to reduce recurrent vascular events in patients with coronary artery disease.
The CONVINCE trial was conducted to see whether colchicine could show similar benefits in patients with non-severe, non-cardioembolic stroke or transient ischemic attack.
Conducted in 16 European countries and Canada, the CONVINCE trial included 3154 patients with a recent non-cardioembolic nondisabling ischemic stroke or high-risk transient ischemic attack. They were randomly assigned to receive colchicine (0.5 mg/d) or placebo.
Key exclusion criteria included evidence of atrial fibrillation or other source of cardioembolism, a defined cause of stroke other than atherosclerosis or small vessel disease, a glomerular filtration rate below 50 mL/min, and the use of drugs that interact with colchicine.
The primary endpoint was a composite of first recurrent ischemic stroke, myocardial infarction, cardiac arrest, or hospitalization for unstable angina. Study participants were followed-up over 36 months.
Results of the primary intention-to-treat analysis showed that the primary endpoint occurred in 153 patients randomized to low-dose colchicine (9.8%) versus 185 in the placebo group (11.8%). This translated into a hazard ratio (HR) of 0.84 (95% CI, 0.68-1.05; P = .12) — a nonsignificant result.

Metformin Initiation Cuts Gout Risk in Prediabetes
TOPLINE:
Metformin use lowers the risk for gout by 32% in individuals with prediabetes; however, the treatment doesn’t change serum urate or C-reactive protein levels.
METHODOLOGY:
- Individuals with prediabetes not only are at an elevated risk for diabetes but also face an increased risk for incident gout. Many previous reports have demonstrated the efficacy of antidiabetic medications in reducing the risk for gout in adults with diabetes.
- This study assessed the gout-lowering properties of metformin in 25,064 individuals with prediabetes (age ≥ 18 years; A1c levels, 5.7%-6.4%) who had never reported A1c levels > 6.4%.
- Patients who were initiated on metformin within 18 months after the diagnosis of prediabetes (n = 1154) were propensity score–matched with those who did not initiate metformin or other antidiabetic medications in this period (n = 13,877) and were followed for a median of 3.9 years for the primary outcome of incident gout.
TAKEAWAY:
- Initiation vs no initiation of metformin resulted in 2.4 fewer cases of gout per 1000 person-years and a 32% reduced relative risk for incident gout (hazard ratio, 0.68; 95% CI, 0.48-0.96).
- The results were consistent across different subgroups stratified on the basis of sex, age (≤ 60 vs > 60 years), estimated glomerular filtration rate (≥ 90 vs < 90 mL/min/1.73 m2), and baseline diuretic use.
- Metformin initiation was not associated with significant changes in serum urate or C-reactive protein levels.
- Metformin use was associated with a reduction in A1c levels and body mass index.
IN PRACTICE:
The authors suggested that “metformin may be important in lowering gout risk in individuals with prediabetes.”
SOURCE:
Javier Marrugo, MD, Department of Medicine, Brigham and Women’s Hospital, Boston, led this study, which was published online in Annals of the Rheumatic Diseases.
LIMITATIONS:
Although gout is more commonly observed in men, around 60% of the study population consisted of women. Owing to the observational nature of this study, exposure misclassifications might have occurred. Misclassification of the outcome is also possible due to the presence of two or more diagnostic codes for gout and/or the combination of urate-lowering therapies or colchicine with at least one diagnostic code.
DISCLOSURES:
This work was supported by the National Institutes of Health. Some authors declared serving as consultants or receiving salary support or consulting fees from various sources.

Vigilance Needed in Gout Treatment to Reduce CVD Risks
NEW YORK — Urate, the culprit of gout, affects the vasculature in multiple ways that can raise cardiovascular risk (CV) in an individual with gout, and following guidelines for gout treatment, including the use of colchicine, can be the key to reducing those risks.
“Guideline-concordant gout treatment, which is essentially an anti-inflammatory urate-lowering strategy, at least improves arterial physiology and likely reduces cardiovascular risk,” Michael H. Pillinger, MD, told attendees at the 4th Annual Cardiometabolic Risk in Inflammatory Conditions conference. Dr. Pillinger is professor of medicine and biochemistry and molecular pharmacology at New York University Grossman School of Medicine, New York City, who has published multiple studies on gout.
He cited evidence that has shown soluble urate stimulates the production of C-reactive protein (CRP), which is a predictor of cardiovascular disease (CVD). Another study, in which Dr. Pillinger participated, demonstrated that gout patients have impaired vascular endothelial function associated with a chronic, low-level inflammatory state, he said.
“There’s good evidence that urate itself affects the vasculature in multiple ways, and I suspect this may be a model for other metabolic effects on vasculature,” Dr. Pillinger said. “Patients with gout have abnormal endothelium in ways that really convey vascular risk.”
Gout, Inflammation, and CVD
However, for rheumatologists to study the association between gout-related inflammation and CVD is “very, very hard,” Dr. Pillinger added. “But I do think that the mechanisms by which gout induces biological changes in the vasculature may provide insights into cardiovascular disease in general.”
One way to evaluate the effects of gout on the endothelium in the clinic is to measure flow-mediated dilation. This technique involves placing an ultrasound probe over the brachial artery and measuring the baseline artery diameter. Then, with the blood pressure cuff over the forearm, inflate it to reduce flow, then release the cuff and measure the brachial artery diameter after the endothelium releases vasodilators.
Dr. Pillinger and colleagues evaluated this technique in 34 patients with gout and 64 controls and found that patients with gout had an almost 50% decrease in flow-mediated dilation, he said. “Interestingly, the higher the urate, the worse the flow; the more the inflammation, the worse the flow, so seemingly corresponding with the severity of the gout,” he said. That raised an obvious question, Dr. Pillinger continued: “If you can treat the gout, can you improve the flow-mediated dilation?”
His group answered that question with a study in 38 previously untreated patients with gout, giving them colchicine 0.6 mg twice daily for a month plus a urate-lowering xanthine oxidase inhibitor (allopurinol or febuxostat) to treat them to a target urate level of < 6 mg/dL. “We saw an increase in endothelial function, and it normalized,” Dr. Pillinger said.
However, some study participants didn’t respond. “They were people with well-established other cardiovascular comorbidities — hypertension, hyperlipidemia,” he said. “I think some people just have vessels that are too damaged to get at them just by fixing their gout problem or their inflammation.”
That means patients with gout need to be treated with colchicine early on to avoid CV problems, Dr. Pillinger added. “We ought to get to them before they have the other problems,” he said.
Managing gout, and the concomitant CV problems, requires vigilance both during and in between flares, Dr. Pillinger said after his presentation.
“We have always taught that patients between flares basically look like people with no gout, but we do know now that patients with gout between flares tend to have what you might call ‘subclinical’ inflammation: CRPs and ESRs [erythrocyte sedimentation rates] that are higher than those of the general population, though not so excessive that they might grab attention,” he said. “We also know that many, if not all, patients between flares have urate deposited in or around their joints, but how these two relate is not fully established.”
Better treatment within 3 months of an acute gout flare may reduce the risk for CV events, he said, but that’s based on speculation more so than clinical data.
Potential Benefits of Targeting Inflammation
“More chronically, we know from the cardiologists’ studies that anti-inflammatory therapy should reduce risk in the high-risk general population,” Dr. Pillinger said. “There are no prospective studies confirming that this approach will work among gout patients, but there is no reason why it shouldn’t work — except perhaps that gout patients may have higher inflammation than the general population and also have more comorbidities, so they could perhaps be more resistant.”
Dr. Pillinger said that his group’s studies and another led by Daniel Solomon, MD, at Brigham and Women’s Hospital in Boston, have indicated that anti-inflammatory strategies in gout will lower CV risk.
“And interestingly,” he added, “our data suggest that colchicine use may lower risk not only in high-risk gout patients but also in gout patients who start with no CAD [coronary artery disease] but who seem to have less incident CAD on colchicine. I see this as identifying that gout patients are intrinsically at high risk for CAD, even if they don’t actually have any, so they represent a population for whom lowering chronic inflammation may help prevent incident disease.”
Dr. Pillinger provided more evidence that the understanding of the relationship between gout, gout flares, and CV risk is evolving, said Michael S. Garshick, MD, who attended the conference and is head of the Cardio-Rheumatology Program at NYU Langone, New York City.
“There’s epidemiologic evidence supporting the association,” Dr. Garshick told this news organization after the conference. “We think that most conditions with immune system activation do tend to have an increased risk of some form of cardiovascular disease, but I think the relationship with gout has been highly underpublicized.”
Many patients with gout tend to have a higher prevalence of traditional cardiometabolic issues, which may compound the relationship, Dr. Garshick added. “However, I would argue that with this patient subset that it doesn’t matter because gout patients have a higher risk of traditional risk factors, and you have to [treat-to-target] those traditional risk factors.”
While the clinical evidence of a link between gout and atherosclerosis may not be conclusive, enough circumstantial evidence exists to believe that treating gout will reduce CV risks, he said. “Some of the imaging techniques do suggest that gouty crystals [are] in the atherosclerotic plaque of gout patients,” Dr. Garshick added. Dr. Pillinger’s work, he said, “is showing us that there are different pathways to develop atherosclerosis.”
Dr. Pillinger disclosed relationships with Federation Bio, Fortress Biotech, Amgen, Scilex, Hikma Pharmaceuticals, LG Chem, and Olatec Therapeutics. Dr. Garshick disclosed relationships with Kiniksa Pharmaceuticals, Agepha Pharma, Bristol Myers Squibb, and Horizon Therapeutics.

NEW YORK — New insights into colchicine’s disruption of the pathway that contributes to arterial inflammation and new clinical studies of the drug could pave the way toward greater use of the anti-inflammatory drug in patients with or at risk for atherosclerotic cardiovascular disease (ASCVD), researchers said at the 4th Annual Cardiometabolic Risk in Inflammatory Conditions conference.
Colchicine was approved by the US Food and Drug Administration (FDA) in June 2023 in a once-daily 0.5-mg formulation under the brand name Lodoco to reduce the risk for major adverse cardiovascular events (MACE) in patients with established atherosclerotic disease or with multiple risk factors for CVD. The Lodoco formulation is slightly smaller than the 0.6-mg formulation that’s taken twice daily for the prophylaxis and treatment of acute gout flares.
In a presentation at the conference, Binita Shah, MD, one of the principal investigators in trials of Lodoco, explained how the inflammatory pathway contributes to atherosclerosis and provided an update on how colchicine disrupts the pathway. Dr. Shah is an associate professor of medicine at New York University in New York City and director of research at NYU Langone Health Interventional Cardiology.
“Colchicine dampens inflammatory markers on neutrophils so that they are less likely to be attracted to inflamed or injured endothelium, which would be the site of where plaque is building up or where the plaque has ruptured in the setting of a heart attack,” Shah told this news organization after her presentation.
The Inflammatory Pathway
Dr. Shah explained that normal coronary endothelium resists adhesion by circulating leukocytes, but inflamed or injured coronary endothelium attracts those neutrophils via two types of selectins: L-selectins on neutrophils and E-selectins on endothelial cells. Those neutrophils then release inflammatory cytokines including interleukin-1 beta (IL-1ß), which then triggers production of IL-6 and, subsequently, high-sensitivity C-reactive protein (hsCRP), which contributes to plaque formation, she said.
“Colchicine affects these pathways with a balance for safety and effect on clinical outcomes, particularly to reduce recurrent myocardial infarction [MI],” Dr. Shah said during her presentation.
Results from the CIRT trial demonstrated that methotrexate is ineffective in blocking the adenosine-mediated anti-inflammatory pathway, Dr. Shah said, so focusing on the IL-1ß–IL-6–hsCRP pathway, which is known to work based on the results of the CANTOS trial, could pay dividends.
“This is where colchicine can potentially play a role,” she said.
Dr. Shah cited a secondary analysis of the CANTOS trial in which the magnitude of hsCRP reduction correlated with a reduction in MI, stroke, or cardiovascular death. The secondary analysis showed that patients who received canakinumab and achieved hsCRP ≥ 2 mg/L had a nonsignificant 5% lower risk and those who reached < 2 mg/L had a statistically significant 25% lower risk than those who received placebo.
The COPE-PCI Pilot trial demonstrated the benefit of targeting the interleukin pathways, she noted.
Further clarification of the role of colchicine in managing patients with acute coronary syndrome may come from two other randomized trials now underway, Dr. Shah said: POPCORN is evaluating colchicine to reduce MACE after noncardiac surgery, and CLEAR SYNERGY is evaluating the best timing for colchicine therapy after an acute MI.
Dr. Shah presented preliminary data from her group from a neutrophil biomarker substudy of CLEAR SYNERGY that isolated neutrophils from patients who had an acute MI. “We treated them with various doses of colchicine and showed that the interaction between those treated neutrophils [and] the endothelial cells were a lot lower; they were less sticky to endothelial cells as colchicine was administered,” she said in her presentation. She added that colchicine also reduced neutrophil chemotaxis and neutrophil activation and potentially inhibited inflammasomes, decreasing IL-1ß production.
What’s more, colchicine has been shown to not affect platelets alone but rather platelets at the site of inflammation or plaque rupture, Dr. Shah added. “At currently used doses, colchicine does not inhibit platelet activity [by] itself, so we’ve never seen increased bleeding events, but it will dampen neutrophils’ ability to latch onto a platelet that could contribute to a clot,” she later told this news organization.
“There are multiple studies, both retrospective studies in gout cohorts as well as prospective studies in the cardiovascular cohort, that all show consistently one thing, which is that colchicine continues to reduce the risk of having a recurrent MI in patients who either have cardiovascular disease or are at high risk of having cardiovascular disease,” she said.
“I think that’s very helpful to know that it’s not just one study — it’s not just a fluke, potentially a play of chance — but multiple studies consistently showing the same thing: That there’s a reduced risk of acute MI.”
Slow to Embrace Colchicine
Despite this evidence, cardiologists and rheumatologists have been slow to embrace colchicine for patients at risk for cardiovascular events, said Michael S. Garshick, MD, who attended the conference and is head of the Cardio-Rheumatology Program at NYU Langone. “What [Shah] really highlighted was that for a number of years now, we’ve had several clinical trials showing the benefit of low-dose colchicine to prevent atherosclerotic cardiovascular events, and yet despite these and that there’s now an indication to use low-dose colchicine to reduce cardiovascular disease, we’re still struggling for this medication to be taken up by the general cardiology community to treat high-risk patients.
“There’s still some work to do to prove that we need to break those barriers,” Dr. Garshick added. Some of the confusion surrounding the use of colchicine for ASCVD may be attributed to the 0.5-mg dose approved for CVD as opposed to the long-approved 0.6-mg dose for gout, he said. “People are generally confused: Is it OK to use the 0.6-mg dose?” Dr. Garshick said.
Potential gastrointestinal side effects may be another concerning factor, although, he added, “we didn’t see any major complications.” Another issue could be polypharmacy in many of these patients, he said.
Dr. Garshick concurred with Shah that the existing evidence supporting the use of colchicine to reduce risk for cardiovascular events is strong, but more will come out. “I think there’s going to be evolving data supporting it,” he said.
Dr. Shah disclosed financial relationships with Philips Volcano and Novo Nordisk. She is a principal investigator of the CLEAR SYNERGY biomarker substudy and the POPCORN trial. Dr. Garshick disclosed relationships with Kiniksa Pharmaceuticals, Agepha Pharma, Bristol Myers Squibb, and Horizon Therapeutics.

Optimized Hospital Care for Gout Improves Uptake of Urate-Lowering Therapy
LIVERPOOL, ENGLAND — Optimizing how people experiencing a gout flare are managed in hospital and then followed-up afterwards can substantially increase the uptake of guideline-recommended urate-lowering therapy (ULT), researchers reported at the annual meeting of the British Society for Rheumatology (BSR).
In a prospective study, 92% of 97 people admitted to hospital for gout flares were using ULT within 6 months of discharge after a multifaceted intervention was introduced. By comparison, 49% of 94 people admitted for gout flares before the introduction of the intervention were taking ULT within the same postdischarge time frame.
Moreover, a higher proportion of individuals had urate blood tests done at least once within the 6-month postdischarge period after the intervention’s introduction (58% vs 32%) and fewer (9% vs 15%) needed repeated hospital treatment.
“Gout is the most common inflammatory arthritis affecting one in 30 adults in the United Kingdom, yet it’s one of the most poorly managed,” study investigator Mark D. Russell, MB, BChir, pointed out during a poster presentation.
“There are very effective treatments,” added Dr. Russell, a rheumatology registrar and postdoctoral research fellow at King’s College London in London, England. “Urate-lowering therapies such as allopurinol, which when taken at the correct dose, in the long term, effectively cures patients of their symptoms and prevents complications.”
Dr. Russell said in an interview that there was still work to be done as the rate of people achieving urate levels below the recommended threshold of 360 micromol/L (6 mg/dL) within 6 months was still low, at 27%, even it if was still better than the 11% seen before the intervention was introduced.
Improving the In- and Post-Hospital Pathway
“We developed and implemented an in-hospital management pathway which encouraged urate-lowering therapy initiation prior to discharge, followed by a post-discharge nurse-led review,” Dr. Russell explained.
The in-hospital pathway was based upon BSR, European Alliance of Associations for Rheumatology, and American College of Rheumatology guidelines and involved diagnosing and managing the gout flare appropriately. This may have been via early joint aspiration, medication, or both, as directed by the rheumatology team. Affected individuals also received education and were directed where to obtain further information on the use of ULT. Outpatient follow-up was considered if an individual had severe or tophaceous gout, recurrent episodes, or contraindications or intolerances to ULT. Otherwise, a rheumatology nurse telephoned the individual 2 weeks later to review symptoms and discuss next steps.
The researchers recorded improvements in in-hospital outcomes. The frequency of in-hospital serum urate level measurements rose from 66% in the 12-month preimplementation period to 93% in the 12-month period after the intervention’s introduction. Almost two thirds (62%) of patients were discharged on ULT compared with 18% preimplementation. And gout-specific recommendations were given 86% of the time compared with 59% before the intervention.
Related Work on Gout Incidence
Separately, Dr. Russell also presented data from a nationwide, population-level cohort study that used data from OpenSAFELY, the secure data analytics platform used by the National Health Service in England.
“We did an analysis previously using the CPRD [Clinical Research Practice Datalink], which is another good primary care database, showing that only a third of people with gout in the UK get urate-lowering drugs, when really it should be the vast majority,” he said in the interview.
“And then we wanted to look at, on top of that, what was the impact of the [COVID-19] pandemic,” Russell added. Specifically, the aim was to look at how the pandemic had affected the incidence, management, and prevalence of gout.
Between March 2015 and February 2023, 246,695 new cases of gout were identified among 17.9 million adults, seen in primary and secondary care.
COVID-19 Pandemic Affected Cases
“The number of new cases of gout dropped by about one third in the first year of the pandemic,” Dr. Russell said. Incidence declined from 1.78 to 1.23 per 1000 adults. “Whether that was through people not feeling comfortable going to their GP [general practitioner] or not being able to get an appointment, we don’t know.”
While there was a subsequent increase in new cases of gout since this time, the rates still haven’t reached what they were before the pandemic. This implies that there could be a substantial number of people who may be undiagnosed because of the pandemic, Dr. Russell suggested.
Moreover, he reported that in 2022-2023, the prevalence of gout was 3.21%, up slightly from the 3.07% recorded 7 years earlier in 2015-2016.
ULT Treatment Rates Low
“If you did see a GP, however, so as long as you saw someone, the treatment wasn’t any worse,” Dr. Russell said. Just under 30% of people with incident gout for whom follow-up data were available had initiated ULT within 6 months of their diagnosis. And, of these new starters, around a quarter had a serum urate level below a target of 360 micromol/L.
“This doesn’t detract from the fact that this is pretty low. Despite guidelines, we’re still not getting the majority of people on these very effective urate-lowering drugs,” Dr. Russell said.
There is perhaps too much reliance on modifying diet and lifestyle, he added, which are important for many reasons but will not do much to lower blood urate levels.
As a final word, Dr. Russell said, “It’s not just a case of preventing a bit of joint pain. People get lots of complications when they’re undertreated — erosive joint damage, work disability, impaired quality of life — and yet we’ve got very cheap, well-tolerated drugs.”
The work was independently funded. Dr. Russell acknowledged grant or research support from Eli Lilly, Janssen, Pfizer, and UCB and receipt of honoraria from AbbVie, Biogen, Eli Lilly, Galapagos, and Menarini.

Separately, Dr. Russell also presented data from a nationwide, population-level cohort study that used data from OpenSAFELY, the secure data analytics platform used by the National Health Service in England.
“We did an analysis previously using the CPRD [Clinical Research Practice Datalink], which is another good primary care database, showing that only a third of people with gout in the UK get urate-lowering drugs, when really it should be the vast majority,” he said in the interview.
“And then we wanted to look at, on top of that, what was the impact of the [COVID-19] pandemic,” Russell added. Specifically, the aim was to look at how the pandemic had affected the incidence, management, and prevalence of gout.
Between March 2015 and February 2023, 246,695 new cases of gout were identified among 17.9 million adults, seen in primary and secondary care.
COVID-19 Pandemic Affected Cases
“The number of new cases of gout dropped by about one third in the first year of the pandemic,” Dr. Russell said. Incidence declined from 1.78 to 1.23 per 1000 adults. “Whether that was through people not feeling comfortable going to their GP [general practitioner] or not being able to get an appointment, we don’t know.”
While there was a subsequent increase in new cases of gout since this time, the rates still haven’t reached what they were before the pandemic. This implies that there could be a substantial number of people who may be undiagnosed because of the pandemic, Dr. Russell suggested.
Moreover, he reported that in 2022-2023, the prevalence of gout was 3.21%, up slightly from the 3.07% recorded 7 years earlier in 2015-2016.
ULT Treatment Rates Low
“If you did see a GP, however, so as long as you saw someone, the treatment wasn’t any worse,” Dr. Russell said. Just under 30% of people with incident gout for whom follow-up data were available had initiated ULT within 6 months of their diagnosis. And, of these new starters, around a quarter had a serum urate level below a target of 360 micromol/L.
“This doesn’t detract from the fact that this is pretty low. Despite guidelines, we’re still not getting the majority of people on these very effective urate-lowering drugs,” Dr. Russell said.
There is perhaps too much reliance on modifying diet and lifestyle, he added, which are important for many reasons but will not do much to lower blood urate levels.
As a final word, Dr. Russell said, “It’s not just a case of preventing a bit of joint pain. People get lots of complications when they’re undertreated — erosive joint damage, work disability, impaired quality of life — and yet we’ve got very cheap, well-tolerated drugs.”
The work was independently funded. Dr. Russell acknowledged grant or research support from Eli Lilly, Janssen, Pfizer, and UCB and receipt of honoraria from AbbVie, Biogen, Eli Lilly, Galapagos, and Menarini.

Gout Increases the Risk for a Wide Range of Cardiovascular Diseases
People with gout are 58% more likely to develop cardiovascular disease (CVD), according to a new analysis. This increased risk was observed across 12 different cardiovascular conditions, including heart failure, arrhythmias, and valve diseases.
“These findings suggest that the organ damage associated with gout is likely to be much broader than originally thought,” Nathalie Conrad, PhD, senior author of the research and cardiovascular epidemiologist at KU Leuven, Leuven, Belgium, said in an email. This could be useful for future research on underlying biological mechanisms driving CVD risk in gout, she added.
While previous research has tied gout to increased cardiovascular risk, these studies “largely focused on coronary heart disease, stroke, and thromboembolic outcomes,” she explained, and have been smaller in size.
This new study included more than 862,000 individuals, which permitted researchers to investigate rarer CVD outcomes such as myocarditis and pericarditis.
For the study, researchers used electronic health records from the UK Clinical Practice Research Datalink, a primary care database that contains anonymized health data for about 22 million individuals. Using these data, they identified more than 152,600 individuals with gout. Patients included in the analysis were diagnosed between 2000 and 2017, younger than 80 years at diagnosis, and free of CVD for at least 12 months after their gout diagnosis.
Patients with gout were compared with nearly 710,000 controls, matched on demographic factors such as age, sex, and geographic region.
Researchers then investigated the incidence of 12 CVDs, including atherosclerotic diseases, degenerative and thromboembolic diseases, and arrythmias, between the two groups from January 1, 2000, to June 30, 2019.
The findings were published in the March 2024 issue of The Lancet Rheumatology. Overall, patients with gout were 58% more likely to develop any CVD than their matched comparators without gout. There was a higher disease incidence among patients with gout for each of the 12 conditions. This association was more pronounced in women (hazard ratio [HR], 1.88) than in men (HR, 1.49), and gout amplified the risk for CVD in younger individuals to a greater extent.
Individuals younger than 45 years with gout were more than twice as likely to develop CVD compared with similarly aged individuals without gout. For comparison, individuals aged 45-54 years with gout were 84% more likely to develop CVD, and individuals aged 55-64 years were 57% more likely to develop CVD than matched controls.
Conduction system disease had the highest incident risk (HR, 1.88), followed by heart failure and valve disease (HR, 1.85 for both).
Individuals with gout had higher rates of comorbidities than the controls, including hypertension, obesity, and dyslipidemia. Overall, CVD risk was slightly attenuated after adjustment for traditional CVD risk factors such as smoking, blood pressure, and body mass index but still significant: Patients with gout had a 31% higher risk for CVD than comparators.
This shows “that known CVD risk factors only explain part of the CVD risks seen in patients with gout,” Dr. Conrad said. Other factors such as inflammation and other disease activity factors could be at play, she explained, which would need to be explored in future research.
The study “shows the whole landscape” of CVD and gout, Michael H. Pillinger, MD, rheumatologist and professor of medicine, biochemistry, and molecular pharmacology at NYU Grossman School of Medicine in New York City, said in an interview. He was not involved with the research.
“Every possible cardiovascular disease that they could think of was something that gout patients had more of than the non-gout patients,” he added. “I think this is going to be a paper that gets cited a lot, at minimum when describing the background of risk when we look at gout patients.”
The study had some limitations, including that researchers were unable to account for how medications such as nonsteroidal anti-inflammatory drugs, corticosteroids, colchicine, or allopurinol may have affected the association between gout and CVD.
“This is because analyses of nonrandomized treatment can be confounded by indication, wherein it is difficult to differentiate the effects of the treatment from underlying disease severity,” the authors wrote.
There was also a large amount of missing data on blood pressure, body mass index, smoking status, and other health information relevant to cardiovascular risk, so sensitivity analyses adjusting for these factors “should be interpreted with caution,” they added.
Dr. Pillinger also noted that the rates of comorbidities in the gout study population were lower than what have been found in US study populations. For example, about 40% of patients with gout in the analysis had hypertension, while other studies have suggested higher rates of 60%-70%, he said. However, it’s not clear if these differences could have affected outcomes. He added that these limitations do not “in any way weaken [the authors’] conclusion.”
The findings call for better strategies to reduce CVD risk in patients with gout, Dr. Conrad noted.
“Further improvements could come from better recognition and intervention on CVD risk factors (eg, through lifestyle changes or drug therapies where they are indicated), as well as proactive screening for heart disease in patients with gout, which could allow early diagnosis and interventions to delay more severe outcomes,” she added.
This study was funded by Research Foundation Flanders. Dr. Conrad was funded by a personal fellowship from the Research Foundation Flanders and a European Society of Cardiology research grant. She received royalties from Oxford University Innovation. Four of Dr. Conrad’s eight coauthors also reported financial relationships with pharmaceutical companies. Dr. Pillinger served as a consultant to Amgen, Federation Bio, Fortress Biotech, and Scilex, and he holds an investigator-initiated grant from Hikma.
