Venous Thromboembolism

Janus kinase inhibitors (JAKis) do not appear to increase the risk for major adverse cardiovascular events (MACE) among people with atopic dermatitis (AD) treated in a real-world setting, suggested the results of a large, US-based, retrospective cohort study.

This holds true even in individuals aged 50 years or older, whose age puts them at increased cardiovascular (CV) risk, said Amina El Ayadi, PhD, of the University of Texas Medical Branch at Galveston. He presented the findings at the recent European Academy of Dermatology and Venereology (EADV) 2024 Congress.

Specifically, the analysis looked at treatment with the oral JAK1 inhibitors upadacitinib (Rinvoq) and abrocitinib (Cibinqo), both approved for treating AD in the United States, and found that the relative risk for MACE, such as acute myocardial infarction, cardiac arrest, stroke, or acute deep vein thrombosis, was ≤ 1.0 compared with those not treated with a JAKi.

Similarly, the relative risk for other CV safety endpoints, such as having an abnormal ECG or pericardial effusion, was also around 1.0. There was a slight increase in the relative risk for arrhythmias, peripheral edema, angina pectoris, or heart failure, but no value went > 1.6 and CIs spanned 1.0, indicating the results lack statistical significance.
 

Reassurance for Dermatologists?

“This suggests that oral administration of these drugs to the patient with atopic dermatitis does not increase the risk of major adverse cardiac events, and dermatologists, based on our data, can safely consider JAK inhibitors for treating moderate to severe dermatitis, even in patients with high risk for these diseases,” El Ayadi said during a late-breaking news session at the meeting.

Yolanda Gilaberte Calzada, MD, PhD, head of the Dermatology Department at Miguel Servet University Hospital in Zaragoza, Spain, who was one of the chairs for the session, said that this was “very good news for us.”

Gilaberte Calzada, president of the Spanish Academy of Dermatology and Venereology, asked if there were any data on the duration of treatment with the two JAKis included in the analysis. El Ayadi said that this was something that would be looked at in future data analyses.

Gilaberte Calzada also observed that because the CIs were wide, with more time, “we will have more defined data.”
 

Analyses Overview

For the two analyses — one in the overall population of patients with AD and the other in those aged 50 years or older — electronic medical record (EMR) data from the TriNetX Research Network were used. This is a global, federated health research network that contains EMRs for more than 275 million patients from over 120 healthcare organizations, El Ayadi explained.

To perform the analyses, the research team queried the TriNetX database to find all patients diagnosed with AD via the International Classification of Diseases, Tenth Revision code L20. They then determined if patients had been treated with JAKi or not, and specifically, with upadacitinib or abrocitinib. Those who had not received any JAKi treatment were the control population.

For the first analysis, no age-specific filter was applied. The investigators identified 1674 people with AD who had been treated with the JAKis and around 1.2 million who had not. Propensity score matching, based on age at diagnosis, biologic sex, and CV comorbidities, was performed to give a total of 1674 patients who had and 1674 who had not been treated with these medications.

In the second analysis, only those aged 50 years or older were considered; 875 patients who had received JAKi treatment were identified and around 250,000 who had not. Propensity score matching based on the same variables gave two groups of 875 people who had or had not taken a JAKi.

Queried over the age cutoff used, El Ayadi noted, “We did an analysis looking at patients 65 and older. However, we came up with lower patient numbers. … We do have this data, and we did not see any significant risk.”

The study was independently supported. El Ayadi and Gilaberte Calzada reported no conflicts of interest in relation to the presented findings.

Aspirin. Once upon a time, everybody over age 50 years was supposed to take a baby aspirin. Now we make it a point to tell people to stop. What is going on?  

Our recommendations vis-à-vis aspirin have evolved at a dizzying pace. The young’uns watching us right now don’t know what things were like in the 1980s. The Reagan era was a wild, heady time where nuclear war was imminent and we didn’t prescribe aspirin to patients. 

That only started in 1988, which was a banner year in human history. Not because a number of doves were incinerated by the lighting of the Olympic torch at the Seoul Olympics — look it up if you don’t know what I’m talking about — but because 1988 saw the publication of the ISIS-2 trial, which first showed a mortality benefit to prescribing aspirin post–myocardial infarction (MI).

Giving patients aspirin during or after a heart attack is not controversial. It’s one of the few things in this business that isn’t, but that’s secondary prevention — treating somebody after they develop a disease. Primary prevention, treating them before they have their incident event, is a very different ballgame. Here, things are messy. 

For one thing, the doses used have been very inconsistent. We should point out that the reason for 81 mg of aspirin is very arbitrary and is rooted in the old apothecary system of weights and measurements. A standard dose of aspirin was 5 grains, where 20 grains made 1 scruple, 3 scruples made 1 dram, 8 drams made 1 oz, and 12 oz made 1 lb - because screw you, metric system. Therefore, 5 grains was 325 mg of aspirin, and 1 quarter of the standard dose became 81 mg if you rounded out the decimal. 

People have tried all kinds of dosing structures with aspirin prophylaxis. The Physicians’ Health Study used a full-dose aspirin, 325 mg every 2 days, while the Hypertension Optimal Treatment (HOT) trial tested 75 mg daily and the Women’s Health Study tested 100 mg, but every other day. 

Ironically, almost no one has studied 81 mg every day, which is weird if you think about it. The bigger problem here is not the variability of doses used, but the discrepancy when you look at older vs newer studies.

Older studies, like the Physicians’ Health Study, did show a benefit, at least in the subgroup of patients over age 50 years, which is probably where the “everybody over 50 should be taking an aspirin” idea comes from, at least as near as I can tell. 

More recent studies, like the Women’s Health Study, ASPREE, or ASPIRE, didn’t show a benefit. I know what you’re thinking: Newer stuff is always better. That’s why you should never trust anybody over age 40 years. The context of primary prevention studies has changed. In the ‘80s and ‘90s, people smoked more and we didn’t have the same medications that we have today. We talked about all this in the beta-blocker video to explain why beta-blockers don’t seem to have a benefit post MI.

We have a similar issue here. The magnitude of the benefit with aspirin primary prevention has decreased because we’re all just healthier overall. So, yay! Progress! Here’s where the numbers matter. No one is saying that aspirin doesn’t help. It does. 

If we look at the 2019 meta-analysis published in JAMA, there is a cardiovascular benefit. The numbers bear that out. I know you’re all here for the math, so here we go. Aspirin reduced the composite cardiovascular endpoint from 65.2 to 60.2 events per 10,000 patient-years; or to put it more meaningfully in absolute risk reduction terms, because that’s my jam, an absolute risk reduction of 0.41%, which means a number needed to treat of 241, which is okay-ish. It’s not super-great, but it may be justifiable for something that costs next to nothing. 

The tradeoff is bleeding. Major bleeding increased from 16.4 to 23.1 bleeds per 10,000 patient-years, or an absolute risk increase of 0.47%, which is a number needed to harm of 210. That’s the problem. Aspirin does prevent heart disease. The benefit is small, for sure, but the real problem is that it’s outweighed by the risk of bleeding, so you’re not really coming out ahead. 

The real tragedy here is that the public is locked into this idea of everyone over age 50 years should be taking an aspirin. Even today, even though guidelines have recommended against aspirin for primary prevention for some time, data from the National Health Interview Survey sample found that nearly one in three older adults take aspirin for primary prevention when they shouldn’t be. That’s a large number of people. That’s millions of Americans — and Canadians, but nobody cares about us. It’s fine. 

That’s the point. We’re not debunking aspirin. It does work. The benefits are just really small in a primary prevention population and offset by the admittedly also really small risks of bleeding. It’s a tradeoff that doesn’t really work in your favor.

But that’s aspirin for cardiovascular disease. When it comes to cancer or DVT prophylaxis, that’s another really interesting story. We might have to save that for another time. Do I know how to tease a sequel or what?

Labos, a cardiologist at Kirkland Medical Center, Montreal, Quebec, Canada, has disclosed no relevant financial relationships.

BOSTON — Patients with COPD are at an increased risk for fatal pulmonary embolism (PE) and may require personalized, targeted thromboprophylaxis. Those are the conclusions of investigators who analyzed public health data and found that patients with COPD have a markedly increased risk for PE-related death, particularly among those aged 65-85 years.

The data suggest that “maybe we should start thinking about if we are admitting a patient with COPD in that specific age group, higher thromboprophylaxis for PE,” said Marwa Oudah, MD, a pulmonary hypertension fellow at the University of Pennsylvania, Philadelphia. She presented her group’s findings in a rapid-fire oral abstract session at the CHEST Annual Meeting.
 

Known Risk Factor

COPD is a known risk factor for PE. To estimate how the obstructive lung disease may contribute to PE-related deaths among patients of varying ages, Oudah and colleagues drew data on deaths due to an underlying cause of PE from 1999 to 2020 from the Centers for Disease Control and Prevention’s WONDER database.

They stratified the patients into two groups — those with or without COPD — whose data were included in the Multiple Causes of Death dataset, according to age groups ranging from 35 years to over 100 years. The investigators calculated proportional mortality ratios in the non-COPD group and applied these to the COPD-positive group among different age ranges to estimate the observed vs expected number of deaths.

A total of 10,434 persons who died from PE and had COPD listed among causes of death were identified. The sample was evenly divided by sex. The peak range of deaths was among those aged 75-84 years.

The authors saw an increase in PE-related mortality among patients with COPD aged 65-85 years (P < .001).

The ratios of observed-to-expected deaths among patients in this age range were “substantially greater than 1” said Oudah, with patients aged 75-79 years at highest risk for PE-related death, with an observed-to-expected ratio of 1.443.

In contrast, the rate of observed deaths among patients aged 85-89 years was similar to the expected rate, suggesting that the COPD-PE interaction may wane among older patients, she said.

Among patients aged 35-64 years, the risk for death from PE was not significantly higher for any of the 5-year age categories.

The investigators emphasized that “given the observed trend, individualized patient assessments are imperative to optimize preventable measures against PE in the aging COPD population.”
 

Confounding Comorbidities

In an interview, a pulmonary specialist who was not involved in the study commented that older persons with COPD tend to have multiple comorbidities that may contribute to the risk for PE.

“Older patients have so many comorbidities, and their risk for pulmonary embolism and thromboembolic disease is pretty high, so I’m not surprised that 75 to 79 years olds are having a higher mortality from PE, but it’s a little difficult to say whether that’s due to COPD,” said Krishna Sundar, MBBS, MD, FCCP, a pulmonary, sleep medicine, and critical care medicine specialist at St. John’s Medical Center in Jackson, Wyoming, who moderated the session.

The authors did not report a study funding source. Oudah and Sundar reported no relevant financial relationships.

In contrast, the rate of observed deaths among patients aged 85-89 years was similar to the expected rate, suggesting that the COPD-PE interaction may wane among older patients, she said.

Among patients aged 35-64 years, the risk for death from PE was not significantly higher for any of the 5-year age categories.

The investigators emphasized that “given the observed trend, individualized patient assessments are imperative to optimize preventable measures against PE in the aging COPD population.”
 

Confounding Comorbidities

In an interview, a pulmonary specialist who was not involved in the study commented that older persons with COPD tend to have multiple comorbidities that may contribute to the risk for PE.

“Older patients have so many comorbidities, and their risk for pulmonary embolism and thromboembolic disease is pretty high, so I’m not surprised that 75 to 79 years olds are having a higher mortality from PE, but it’s a little difficult to say whether that’s due to COPD,” said Krishna Sundar, MBBS, MD, FCCP, a pulmonary, sleep medicine, and critical care medicine specialist at St. John’s Medical Center in Jackson, Wyoming, who moderated the session.

BOSTON — Patients with COPD are at an increased risk for fatal pulmonary embolism (PE) and may require personalized, targeted thromboprophylaxis. Those are the conclusions of investigators who analyzed public health data and found that patients with COPD have a markedly increased risk for PE-related death, particularly among those aged 65-85 years.

The data suggest that “maybe we should start thinking about if we are admitting a patient with COPD in that specific age group, higher thromboprophylaxis for PE,” said Marwa Oudah, MD, a pulmonary hypertension fellow at the University of Pennsylvania, Philadelphia. She presented her group’s findings in a rapid-fire oral abstract session at the CHEST Annual Meeting.
 

Known Risk Factor

COPD is a known risk factor for PE. To estimate how the obstructive lung disease may contribute to PE-related deaths among patients of varying ages, Oudah and colleagues drew data on deaths due to an underlying cause of PE from 1999 to 2020 from the Centers for Disease Control and Prevention’s WONDER database.

They stratified the patients into two groups — those with or without COPD — whose data were included in the Multiple Causes of Death dataset, according to age groups ranging from 35 years to over 100 years. The investigators calculated proportional mortality ratios in the non-COPD group and applied these to the COPD-positive group among different age ranges to estimate the observed vs expected number of deaths.

A total of 10,434 persons who died from PE and had COPD listed among causes of death were identified. The sample was evenly divided by sex. The peak range of deaths was among those aged 75-84 years.

The authors saw an increase in PE-related mortality among patients with COPD aged 65-85 years (P < .001).

The ratios of observed-to-expected deaths among patients in this age range were “substantially greater than 1” said Oudah, with patients aged 75-79 years at highest risk for PE-related death, with an observed-to-expected ratio of 1.443.

In contrast, the rate of observed deaths among patients aged 85-89 years was similar to the expected rate, suggesting that the COPD-PE interaction may wane among older patients, she said.

BOSTON — The sooner that patients with acute pulmonary embolism (PE) get treated with mechanical thrombectomy, the greater the likelihood that they will have favorable short- and long-term outcomes, regardless of their degree of initial risk, a study of registry data showed.

Among nearly 800 patients with acute PE whose data are recorded in the FlowTriever All-Comer Registry for Patient Safety and Hemodynamics (FLASH), a prospective multicenter registry of individuals treated with mechanical thrombectomy using the FlowTriever system (Inari Medical), shorter time from admission to mechanical thrombectomy was associated with significantly greater reductions in intraprocedural mean and systolic pulmonary artery pressures (PAP), greater reductions in the right ventricular/left ventricular (RV/LV) ratio, and longer 6-minute walk times at 6 months, reported Krunal H. Patel, MD, a pulmonary and critical care fellow at the Lewis Katz School of Medicine at Temple University Hospital in Philadelphia.

“Mechanical thrombectomy in the FLASH registry showed a mortality benefit. I think as time progresses and mechanical thrombectomy becomes more popular, we’re just going to need to figure out what is the ideal time for intervention,” he said during an oral abstract session at the American College of Chest Physicians (CHEST) 2024 Annual Meeting.

“There’s mortality benefit in any case whether the patient is high-risk or intermediate-high. This is a thought-provoking retrospective analysis that says that early intervention is probably better than doing it late, but regardless, the FLASH registry trial showed that early thrombectomy or thrombectomy in general shows positive mortality benefit,” Patel said in an interview.

He likened the challenge for pulmonary and critical care specialists to that of interventional cardiologists, who have determined that the ideal window for starting percutaneous coronary interventions is within 90 minutes of the patient’s arrival at the facility.

“I think we have to get our ‘door-to-balloon’ time for PE care,” he said.
 

Study Details

Patel and colleague Parth M. Rali, MD, FCCP, associate professor of thoracic medicine at Temple, conducted a retrospective review of data on 787 US patients in the FLASH registry for whom time to mechanical thrombectomy data were available. They stratified the patients into short and long time to mechanical thrombectomy groups, with “short” defined as ≤ 12 hours of presentation and “long” as > 12 hours.

They found that the median time to thrombectomy was 19.68 hours. In all, 242 patients (31%) were treated within the short window, and the remaining 545 patients (69%) were treated after at least 12 hours had passed.

Comparing clinical characteristics between the groups, the investigators noted that significantly more patients in the short time group vs long time group were categorized as high-risk (11.2% vs 6.2%; P = .0026). This difference is likely due to the need for greater urgency among high-risk patients, Patel said.

Patients in the short time group also had significantly higher baseline RV/LV ratios and lactate levels, but baseline dyspnea scores and pre-procedure median and systolic PAP were similar between the groups.

The mean time to thrombectomy was 6.08 hours in the short time group vs 34.04 hours in the long time group. Their respective median times were 6.01 and 24.73 hours.

The procedural time was similar between the groups, at 45 and 42 minutes, respectively.

The location of the treated thrombus was central only in 35.1% and 26.5% patients in the short and long time groups, respectively. Lobar-only thrombi were treated in 7.9% and 14.3%, respectively, and both central and lobar thrombi were treated in 57.0% and 59.2%, respectively.

Both 48-hour and 30-day all-cause mortality rates were similar between the groups (0.4%/0.2% and 0.5%/1.0%).

Patients in the short time group had slightly but significantly longer post-procedure hospital and intensive care unit stays, but 30-day readmission rates — whether for PE- or non-PE–related causes — were similar.

Where the differences between the groups really showed, however, were PAP reductions over baseline, with decline in median pressures of −8.7 mm Hg in the short group vs −7.2 mm Hg in the long group (P = .0008), and drops in systolic PAP of −14.4 vs −12.1 mm Hg, respectively (P = .0011).

In addition, reductions in RV/LV ratios from baseline were also significantly greater among patients whose thrombectomies had been expedited at the 48-hour, 30-day, and 6-month follow-up periods.

At 6 months, patients who had received mechanical thrombectomy within 12 hours also had significantly longer 6-minute walk distances (442.2 vs 390.5 m; P = .0032).
 

Low Thrombolysis Rate

Following his presentation, session co-moderator Galina Glazman-Kuczaj, MD, from the Division of Pulmonary and Critical Care Medicine at Albany Med Health System, Albany, New York, asked Patel what percentage of patients, if any, had received thrombolytic therapy before the thrombectomy procedure.

He noted that only 1% or 2% patients in the FLASH registry received thrombolysis.

In an interview, Glazman-Kuczaj said that “it was reassuring for [Patel] to report that it was only a small population of patients who got thrombolysis beforehand in either group because you would expect that maybe people in the group that took longer to have a thrombectomy got some thrombolysis beforehand and that perhaps they were more stable, but it seems like thrombectomy was the first-line treatment in both groups.”

The FLASH Registry is funded by Inari Medical. Patel and Glazman-Kuczaj reported no relevant financial relationships.

BOSTON — Patients with pulmonary embolism (PE) who also present with interstitial lung disease (ILD) have worse outcomes with respect to in-hospital mortality, length of hospital stay, hospital cost, and all-cause readmission, according to results from a new retrospective analysis.

“There’s a lot of evidence now that demonstrates that ILD, in general, leads to worse mortality, morbidity in hospital complications, and overall [outcomes]. It’s not hard to extrapolate this to pulmonary embolism outcomes, too. Unfortunately, there’s not a whole lot of evidence out there to really demonstrate it,” Leah Yuan, MD, said during a presentation of the results at the American College of Chest Physicians (CHEST) 2024 Annual Meeting.

The question is complicated by the nebulous nature of ILD, which includes a diverse set of diseases and etiologies, and different levels of inflammation and fibrosis. It has been employed in the Pulmonary Embolism Severity Index but counts for only 10 points out of 210. “If you look at ILD and PE outcomes, there’s nothing really out there [in the literature],” Yuan said in an interview. She is a resident physician at Cook County Health and Hospitals System.

The new study suggested that ILD could have an important influence and perhaps should have greater weight in risk stratification of patients with PE, she said. “We looked at all-cause readmissions and we looked at in-hospital mortality, [both] of which are significant for increased odds ratio. One thing that I’m very curious to see is whether there is increased PE readmissions [associated with ILD], which is something that we couldn’t find to be significant in our study,” said Yuan.

The researchers used data from hospitalizations for PE drawn from the Nationwide Readmissions Database in 2019, using International Classification of Diseases, Tenth Revision, codes to identify admissions. Among a total of 105,133 patients admitted for PE, 158 patients also had ILD. The mean age was 63.6 years for those without ILD (SD, 0.1) and 66.5 years for those with ILD (SD, 1.3).

Admission with ILD was associated with all-cause readmission (odds ratio [OR], 4.12; P < .01), in-hospital mortality (OR, 2.17; P = .01), a longer length of stay (+2.07 days; P < .01), and higher hospitalization charges (+$22,627; P < .01).

In the Q&A period after the presentation, Parth Rali, MD, professor of thoracic medicine and surgery at Temple University, Philadelphia, suggested phenotyping patients to better understand the location of the PE in relation to the ILD. “It may not fall into your classic PE classification. It may just depend on where the clot is in relationship to the interstitial lung disease. I think that’s where the field is going to evolve,” he later said in an interview.

“What is interesting is that patients with interstitial lung disease have a lot of fibrotic disease, and they do not need to have a large clot burden to make them sick. An example [is someone] who has undergone a lung transplant evaluation, and if their right lung is completely diseased from interstitial lung disease and if they get a big blood clot on the right side, it doesn’t affect them because the lung is already fibrotic, so the clot doesn’t matter. If they get a small clot [in the left lung], even though if you look at the standard PE classification they may qualify as a low-risk PE or even as an intermediate-low-risk PE, they are much sicker because that’s the functioning part of the lung,” said Rali.

He advised physicians to pay close attention to the location of PEs in relation to fibrotic tissue in patients with ILD. A PE in healthy lung tissue could have an outsized effect on hemodynamics, whereas a PE in fibrotic tissue may be clinically insignificant and not require treatment. “So it goes both ways: You don’t overtreat and you don’t undertreat,” Rali said.

Yuan and Rali disclosed no relevant financial relationships.

A PE in healthy lung tissue could have an outsized effect on hemodynamics, whereas a PE in fibrotic tissue may be clinically insignificant and not require treatment. “So it goes both ways: You don’t overtreat and you don’t undertreat,” Rali said.

Yuan and Rali disclosed no relevant financial relationships.

BOSTON — The use of sodium-glucose cotransporter-2 (SGLT2) inhibitors is associated with reduced short- and long-term mortality among patients with pulmonary arterial hypertension (PAH), according to results from a new propensity score–matched analysis.

“There are a lot of new studies that show benefits [of SGLT2 inhibitors] in heart failure, in [chronic kidney disease], and of course, in diabetes. Group one pulmonary hypertension includes not only the inflammatory cascades but also fibrotic and neurovascularization, and all these different parts of the pathophysiology are linked to each other. There are studies that show that SGLT2 inhibitors can have an impact on inflammatory cascades, fibrosis, and vascular remodeling in general. Together, all this data triggered this idea for me, and that’s when I decided to conduct further studies,” said Irakli Lemonjava, MD, who presented the study at the American College of Chest Physicians (CHEST) 2024 Annual Meeting.

The researchers drew data on 125,634 adult patients from the TriNetX database who were diagnosed with PAH after January 1, 2013. They used propensity score matching to account for demographic characteristics and 10 organ system disorders to compare patients with exposure to SGLT2 inhibitors (canagliflozin, dapagliflozin, empagliflozin, or ertugliflozin; n = 6238) with those without such exposure (n = 6243).

At 1 year, 8.1% of patients taking SGLT2 inhibitors had died, compared with 15.5% of patients not taking SGLT2 inhibitors (risk reduction [RR], 0.52; P < .0001). The values were 13% and 22.5% (RR, 0.579; P < .0001) at 3 years and 14.6% and 25% at 5 years (RR, 0.583; P < .0001).

The study generated discussion during the Q&A period following the talk. One audience member asked if the group was able to access patients both inside and outside the United States. “Because I wonder if access to GLP2 inhibitors is actually a surrogate marker for access to other medications,” the questioner said.

Although the finding is intriguing, it shouldn’t change clinical practice, according to Lemonjava. “I don’t think we can make any changes based on what I shared today. Our purpose was to trigger the question. I think the numbers are so impressive that it will trigger more studies. I think if in the future it’s demonstrated by clinical trials that [SGLT2 inhibitors are beneficial], it will not be a problem to prescribe for someone with pulmonary arterial hypertension because they do not have many side effects,” he said. Lemonjava is a resident physician at Jefferson Einstein Philadelphia Hospital, Philadelphia.

Session co-moderator said Syed Rehan Quadery, MD, praised the study but emphasized the remaining uncertainty. “It’s an excellent proof of concept study. More trials need to [be done] on it, and we don’t understand the mechanism of action in which it improves survival in patients with pulmonary artery hypertension. The majority of the patients with pulmonary hypertension are much older and they have comorbidities, including cardiovascular risk factors, and maybe that is one of the ways in which this drug helps. Plus, there are multiple mechanisms in which it may be working, including anti-inflammatory as well as antiproliferative mechanisms through inhibiting the Notch-3 signaling pathway,” said Quadery, who is a consultant respiratory physician at National Pulmonary Hypertension Unit, Dublin, Ireland.

Quadery and his co-moderator Zeenat Safdar, MD, both noted that SGLT2 inhibitors have already been demonstrated to improve outcomes in heart failure. “[SGLT2 inhibition] improves survival, it decreases hospitalization, it improves morbidity and mortality. There are a lot of things that can be shown in different [animal or in vitro] models. In humans, we actually don’t know exactly how it works, but we know that it does. If it works in left heart failure, it also [could] work in right heart failure,” said Safdar, who is the director of the Houston Methodist Lung Center, Houston Methodist Hospital, Houston.

The study was independently supported. Lemonjava, Quadery, and Safdar reported no relevant financial relationships.

TOPLINE:

Current use of hydroxychloroquine is associated with a lower risk for myocardial infarction (MI), stroke, and other thromboembolic events in patients with systemic lupus erythematosus (SLE). This protective effect diminishes after discontinuation of hydroxychloroquine treatment.

METHODOLOGY:

• Researchers used a nested case-control design to evaluate the association between exposure to hydroxychloroquine and the risk for cardiovascular events in patients with SLE.
• They included 52,883 adults with SLE (mean age, 44.23 years; 86.6% women) identified from the National System of Health Databases, which includes 99% of the French population.
• Among these, 1981 individuals with composite cardiovascular conditions were matched with 16,892 control individuals without cardiovascular conditions.
• Patients were categorized on the basis of hydroxychloroquine exposure into current users (last exposure within 90 days before a cardiovascular event), remote users (91-365 days before), and nonusers (no exposure within 365 days).
• The study outcomes included a composite of cardiovascular events, including MI, stroke (including transient ischemic attack), and other thromboembolic events such as phlebitis, thrombophlebitis, venous thrombosis, venous thromboembolism, and pulmonary embolism.

TAKEAWAY:

• Current hydroxychloroquine users had lower odds of experiencing a composite cardiovascular outcome than nonusers (adjusted odds ratio [aOR], 0.63; 95% CI, 0.57-0.70).
• The odds of MI (aOR, 0.72; 95% CI, 0.60-0.87), stroke (aOR, 0.71; 95% CI, 0.61-0.83), and other thromboembolic events (aOR, 0.58; 95% CI, 0.48-0.69) were also lower among current users than among nonusers.
• No significant association was found for remote hydroxychloroquine exposure and the risk for composite cardiovascular events, MI, stroke, and other thromboembolic events.

IN PRACTICE:

“These findings support the protective association of hydroxychloroquine against CV [cardiovascular] events and underscore the importance of continuous hydroxychloroquine therapy for patients diagnosed with SLE,” the authors wrote.

SOURCE:

The study was led by Lamiae Grimaldi-Bensouda, PharmD, PhD, Department of Pharmacology, Hospital Group Paris-Saclay, Assistance Publique-Hôpitaux de Paris, France. It was published online on August 30, 2024, in JAMA Network Open.

LIMITATIONS:

The observational nature of the study may have introduced confounding. Current hydroxychloroquine users were younger than nonusers, with an average age difference of almost 5 years. Current hydroxychloroquine users had a twofold longer duration of onset of SLE and had a higher prevalence of chronic kidney disease compared with nonusers.

DISCLOSURES:

This study was funded by the Banque pour l’Investissement, Deeptech. Some authors declared having financial ties with various institutions and companies outside of the current study.

LIVERPOOL, ENGLAND — People with rheumatoid arthritis (RA) have a consistently higher risk for venous thromboembolism (VTE) than the general population, but the reasons for this remain unclear, research presented at the annual meeting of the British Society for Rheumatology (BSR) reaffirmed.

Regardless of age, sex, body mass index (BMI), duration of disease, use of estrogen-based oral contraceptives, or hormone replacement therapy (HRT), people with RA are more likely to experience a pulmonary embolism or deep vein thrombosis than those without RA.

However, “these are rare events,” James Galloway, MBChB, PhD, professor of rheumatology and deputy head of the Centre for Rheumatic Diseases at King’s College London in England, said at the meeting.

In one analysis of data from 117,050 individuals living in England and Wales that are held within a large primary care practice database, Dr. Galloway and colleagues found that the unadjusted incidence of VTE in people diagnosed with RA (n = 23,410) was 0.44% vs 0.26% for matched controls within the general population (n = 93,640).
 

RA and VTE Risk

The overall risk for VTE was 46% higher among people with RA than among those without, although the absolute difference was small, Dr. Galloway reported.

“RA is associated with an increased risk of VTE; that’s been well described over the years,” Dr. Galloway told this news organization. Past research into why there is an elevated risk for VTE in patients with RA has often focused on the role of disease activity and inflammation.

“In the last few years, a new class of drugs, the JAK [Janus kinase] inhibitors, have emerged in which we have seen a signal of increased VTE risk from a number of studies. And I think that puts a spotlight on our understanding of VTE risk,” Dr. Galloway said.

He added “JAK inhibitors are very powerful at controlling inflammation, but if you take away inflammation, there is still an excess risk. What else could be driving that?”

To examine the excess risk for VTE seen in people with RA, Dr. Galloway and colleagues performed three separate analyses using data collected between January 1999 and December 2018 by the Royal College of General Practitioners Research and Surveillance Center.

One analysis looked at VTE risk according to age, sex, and BMI; another looked at the effect of the duration of RA; and a third analysis focused on the use of estrogen-based oral contraceptives or HRT.

For all three analyses, those with RA were matched in a 4:1 ratio to people from the general population without RA on the basis of current age, sex, calendar time, and years since registration at the primary care practice.
 

Observational Data Challenged

“These are observational data, so it’s important to weigh up the strengths and limitations,” Dr. Galloway acknowledged. Strengths are the large sample size and long follow-up provided by the database, which assesses and monitors more than 2000 primary care practices in England and Wales.

Confounding is still possible, despite adjusting for multiple factors that included sociodemographic factors; clinical features; and VTE risk factors such as smoking status, alcohol use, thrombophilia, reduced mobility, lower limb fracture, and a family history of VTE if data had been available. There wasn’t information on disease activity, for example, and disease duration was used as a surrogate marker for this.

Sitting in the audience, Marwan Bukhari, MBBS, PhD, challenged the population-matching process.

“Do you think maybe it was the matching that was the problem?” asked Dr. Bukhari, who is consultant rheumatologist at University Hospitals of Morecambe Bay NHS Foundation Trust and an honorary senior lecturer at the University of Manchester, both in England.

“They’re not entirely matched completely, correctly. Even if it is 4:1, there’s a difference between the populations,” he said.
 

Age, Sex, and Bodyweight

Over an average of 8.2 years’ follow-up, the adjusted hazard ratios (aHRs) comparing VTE risk in women and men with and without RA were a respective 1.62 and 1.52. The corresponding aHRs for VTE according to different age groups were 2.13 for age 18-49 years, 1.57 for age 50-69 years, and 1.34 for age 70 years and older.

“The highest excess risk was in the youngest age group,” Dr. Galloway pointed out, “but all age groups showing a significant increased risk of venous thromboembolism.”

Similar findings were seen across different BMI categories, with the highest risk occurring in those in the lowest BMI group. The aHRs were 1.66, 1.60, and 1.41 for the BMI categories of less than 25 kg/m2, 25-30 kg/m2, and more than 30 kg/m2, respectively.
 

Duration of RA

As for disease duration, nearly two thirds (63.9%) of the 23,410 adults with RA included in this analysis were included at or within 2 years of a diagnosis of RA, 7.8% within 2-5 years of diagnosis, 9.8% within 5-10 years of diagnosis, and 18.5% at 10 or more years after diagnosis.

The aHR for an increased relative risk for VTE in people with RA vs the control group ranged from 1.49 for 0-2 years of diagnosis up to 1.63 for more than 10 years since diagnosis.

“We could see no evidence that the VTE excess risk in rheumatoid arthritis was with a specific time since diagnosis,” Dr. Galloway said in the interview. “It appears that the risk is increased in people with established RA, whether you’ve had the disease for 2 years or 10 years.”

Similar findings were also seen when they looked at aHRs for pulmonary embolism (1.46-2.02) and deep vein thrombosis (1.43-1.89) separately.
 

Oral Contraceptives and HRT

Data on the use of estrogen-based oral contraceptives or HRT were detailed in a virtual poster presentation. In this analysis, there were 16,664 women with and 65,448 without RA, and the average follow-up was 8.3 years.

“The number of people available for this analysis was small, and bigger studies are needed,” Dr. Galloway said in the interview. Indeed, in the RA group, just 3.3% had used an estrogen-based oral contraceptive and 4.5% had used HRT compared with 3.9% and 3.8% in the control group, respectively.

The overall VTE risk was 52% higher in women with RA than in those without RA.

Risk for VTE was higher among women with RA regardless of the use of estrogen-based oral contraceptives or not (aHRs, 1.43 and 1.52, respectively) and regardless of the use of HRT or not (aHRs, 2.32 and 1.51).
 

Assess and Monitor

Together these data increase understanding of how age, gender, obesity, duration of disease, and estrogen-based contraception and HRT may make a difference to someone’s VTE risk.

“In all people with RA, we observe an increased risk of venous thromboembolism, and that is both relevant in a contemporary era when we think about prescribing and the different risks of drugs we use for therapeutic strategies,” Dr. Galloway said.

The overall take-home message, he said, is that VTE risk should be considered in everyone with RA and assessed and monitored accordingly. This includes those who may have traditionally been thought of as having a lower risk than others, such as men vs women, younger vs older individuals, and those who may have had RA for a few years.

The research was funded by Pfizer. Dr. Galloway reported receiving honoraria from Pfizer, AbbVie, Biovitrum, Bristol Myers Squibb, Celgene, Chugai, Galapagos, Janssen, Lilly, Novartis, Roche, Sanofi, Sobi, and UCB. Two coauthors of the work were employees of Pfizer. Dr. Bukhari had no conflicts of interest and was not involved in the research.

“Do you think maybe it was the matching that was the problem?” asked Dr. Bukhari, who is consultant rheumatologist at University Hospitals of Morecambe Bay NHS Foundation Trust and an honorary senior lecturer at the University of Manchester, both in England.

“They’re not entirely matched completely, correctly. Even if it is 4:1, there’s a difference between the populations,” he said.
 

Age, Sex, and Bodyweight

Over an average of 8.2 years’ follow-up, the adjusted hazard ratios (aHRs) comparing VTE risk in women and men with and without RA were a respective 1.62 and 1.52. The corresponding aHRs for VTE according to different age groups were 2.13 for age 18-49 years, 1.57 for age 50-69 years, and 1.34 for age 70 years and older.

“The highest excess risk was in the youngest age group,” Dr. Galloway pointed out, “but all age groups showing a significant increased risk of venous thromboembolism.”

Similar findings were seen across different BMI categories, with the highest risk occurring in those in the lowest BMI group. The aHRs were 1.66, 1.60, and 1.41 for the BMI categories of less than 25 kg/m2, 25-30 kg/m2, and more than 30 kg/m2, respectively.
 

Duration of RA

As for disease duration, nearly two thirds (63.9%) of the 23,410 adults with RA included in this analysis were included at or within 2 years of a diagnosis of RA, 7.8% within 2-5 years of diagnosis, 9.8% within 5-10 years of diagnosis, and 18.5% at 10 or more years after diagnosis.

The aHR for an increased relative risk for VTE in people with RA vs the control group ranged from 1.49 for 0-2 years of diagnosis up to 1.63 for more than 10 years since diagnosis.

“We could see no evidence that the VTE excess risk in rheumatoid arthritis was with a specific time since diagnosis,” Dr. Galloway said in the interview. “It appears that the risk is increased in people with established RA, whether you’ve had the disease for 2 years or 10 years.”

Similar findings were also seen when they looked at aHRs for pulmonary embolism (1.46-2.02) and deep vein thrombosis (1.43-1.89) separately.
 

Oral Contraceptives and HRT

Data on the use of estrogen-based oral contraceptives or HRT were detailed in a virtual poster presentation. In this analysis, there were 16,664 women with and 65,448 without RA, and the average follow-up was 8.3 years.

“The number of people available for this analysis was small, and bigger studies are needed,” Dr. Galloway said in the interview. Indeed, in the RA group, just 3.3% had used an estrogen-based oral contraceptive and 4.5% had used HRT compared with 3.9% and 3.8% in the control group, respectively.

The overall VTE risk was 52% higher in women with RA than in those without RA.

Risk for VTE was higher among women with RA regardless of the use of estrogen-based oral contraceptives or not (aHRs, 1.43 and 1.52, respectively) and regardless of the use of HRT or not (aHRs, 2.32 and 1.51).
 

Assess and Monitor

Together these data increase understanding of how age, gender, obesity, duration of disease, and estrogen-based contraception and HRT may make a difference to someone’s VTE risk.

“In all people with RA, we observe an increased risk of venous thromboembolism, and that is both relevant in a contemporary era when we think about prescribing and the different risks of drugs we use for therapeutic strategies,” Dr. Galloway said.

The overall take-home message, he said, is that VTE risk should be considered in everyone with RA and assessed and monitored accordingly. This includes those who may have traditionally been thought of as having a lower risk than others, such as men vs women, younger vs older individuals, and those who may have had RA for a few years.

The research was funded by Pfizer. Dr. Galloway reported receiving honoraria from Pfizer, AbbVie, Biovitrum, Bristol Myers Squibb, Celgene, Chugai, Galapagos, Janssen, Lilly, Novartis, Roche, Sanofi, Sobi, and UCB. Two coauthors of the work were employees of Pfizer. Dr. Bukhari had no conflicts of interest and was not involved in the research.

LIVERPOOL, ENGLAND — People with rheumatoid arthritis (RA) have a consistently higher risk for venous thromboembolism (VTE) than the general population, but the reasons for this remain unclear, research presented at the annual meeting of the British Society for Rheumatology (BSR) reaffirmed.

Regardless of age, sex, body mass index (BMI), duration of disease, use of estrogen-based oral contraceptives, or hormone replacement therapy (HRT), people with RA are more likely to experience a pulmonary embolism or deep vein thrombosis than those without RA.

However, “these are rare events,” James Galloway, MBChB, PhD, professor of rheumatology and deputy head of the Centre for Rheumatic Diseases at King’s College London in England, said at the meeting.

In one analysis of data from 117,050 individuals living in England and Wales that are held within a large primary care practice database, Dr. Galloway and colleagues found that the unadjusted incidence of VTE in people diagnosed with RA (n = 23,410) was 0.44% vs 0.26% for matched controls within the general population (n = 93,640).
 

RA and VTE Risk

The overall risk for VTE was 46% higher among people with RA than among those without, although the absolute difference was small, Dr. Galloway reported.

“RA is associated with an increased risk of VTE; that’s been well described over the years,” Dr. Galloway told this news organization. Past research into why there is an elevated risk for VTE in patients with RA has often focused on the role of disease activity and inflammation.

“In the last few years, a new class of drugs, the JAK [Janus kinase] inhibitors, have emerged in which we have seen a signal of increased VTE risk from a number of studies. And I think that puts a spotlight on our understanding of VTE risk,” Dr. Galloway said.

He added “JAK inhibitors are very powerful at controlling inflammation, but if you take away inflammation, there is still an excess risk. What else could be driving that?”

To examine the excess risk for VTE seen in people with RA, Dr. Galloway and colleagues performed three separate analyses using data collected between January 1999 and December 2018 by the Royal College of General Practitioners Research and Surveillance Center.

One analysis looked at VTE risk according to age, sex, and BMI; another looked at the effect of the duration of RA; and a third analysis focused on the use of estrogen-based oral contraceptives or HRT.

For all three analyses, those with RA were matched in a 4:1 ratio to people from the general population without RA on the basis of current age, sex, calendar time, and years since registration at the primary care practice.
 

Observational Data Challenged

“These are observational data, so it’s important to weigh up the strengths and limitations,” Dr. Galloway acknowledged. Strengths are the large sample size and long follow-up provided by the database, which assesses and monitors more than 2000 primary care practices in England and Wales.

Confounding is still possible, despite adjusting for multiple factors that included sociodemographic factors; clinical features; and VTE risk factors such as smoking status, alcohol use, thrombophilia, reduced mobility, lower limb fracture, and a family history of VTE if data had been available. There wasn’t information on disease activity, for example, and disease duration was used as a surrogate marker for this.

Sitting in the audience, Marwan Bukhari, MBBS, PhD, challenged the population-matching process.

“Do you think maybe it was the matching that was the problem?” asked Dr. Bukhari, who is consultant rheumatologist at University Hospitals of Morecambe Bay NHS Foundation Trust and an honorary senior lecturer at the University of Manchester, both in England.

There is insufficient evidence that drugs targeting the Janus kinase–signal transducer and activator of transcription (JAK-STAT) pathway increase the risk of cardiovascular or thrombotic complications in people undergoing treatment for a variety of dermatological conditions, at least in the short term, say the authors of a new meta-analysis published in JAMA Dermatology.

Considering data on over 17,000 patients with different dermatoses from 45 placebo-controlled randomized clinical trials with an average follow up of 16 weeks, they found there was no significant increase in the occurrence of major adverse cardiovascular events (MACE) or venous thromboembolism (VTE) in people with dermatoses treated with JAK-STAT inhibitors, compared with placebo.

The I² statistic was 0.00% for both MACE and VTE comparing the two arms, indicating that the results were unlikely to be due to chance. There was no increased risk in MACE between those on placebo and those on JAK-STAT inhibitors, with a risk ratio (RR) of 0.47; or for VTE risk, with an RR of 0.46.

Similar findings were obtained when data were analyzed according to the dermatological condition being treated, mechanism of action of the medication, or whether the medication carried a boxed warning.

These data “suggest inconsistency with established sentiments,” that JAK-STAT inhibitors increase the risk for cardiovascular events, Patrick Ireland, MD, of the University of New South Wales, Randwick, Australia, and coauthors wrote in the article. “This may be owing to the limited time frames in which these rare events could be adequately captured, or the ages of enrolled patients being too young to realize the well established heightened risks of developing MACE and VTE,” they suggested.

However, the findings challenge the notion that the cardiovascular complications of these drugs are the same in all patients; dermatological use may not be associated with the same risks as with use for rheumatologic indications.
 

Class-Wide Boxed Warning

“JAK-STAT [inhibitors] have had some pretty indemnifying data against their use, with the ORAL [Surveillance] study demonstrating increased all-cause mortality, cardiovascular events, venous thromboembolism, and malignancy,” Dr. Ireland said in an interview.

ORAL Surveillance was an open-label, postmarketing trial conducted in patients with rheumatoid arthritis treated with tofacitinib or a tumor necrosis factor (TNF) inhibitor. The results led the US Food and Drug Administration to require information about the risks of serious heart-related events, cancer, blood clots, and death in a boxed warning for JAK-STAT inhibitors in 2022.

“I think it’s important to recognize that these [ORAL Surveillance participants] are very different patients to the typical dermatological patient being treated with a JAK-STAT [inhibitors], with newer studies demonstrating a much safer profile than initially thought,” Dr. Ireland said.
 

Examining Risk in Dermatological Conditions

The meta-analysis performed by Dr. Ireland and associates focused specifically on the risk for MACE and VTE in patients being treated for dermatological conditions, and included trials published up until June 2023. Only trials that had included a placebo arm were considered; pooled analyses, long-term extension trial data, post hoc analyses, and pediatric-specific trials were excluded.

Most (25) of the trials were phase 2b or phase 3 trials, 18 were phase 2 to 2b, and two were phase 1 trials. The studies included 12,996 participants, mostly with atopic dermatitis or psoriasis, who were treated with JAK-STAT inhibitors, which included baricitinib (2846 patients), tofacitinib (2470), upadacitinib (2218), abrocitinib (1904), and deucravacitinib (1492), among others. There were 4925 patients on placebo.

Overall, MACE — defined as a combined endpoint of acute myocardial infarction, stroke, cardiovascular mortality, heart failure, and unstable angina, as well as arterial embolism — occurred in 13 of the JAK-STAT inhibitor-treated patients and in four of those on placebo. VTE — defined as deep vein thrombosis, pulmonary embolism, and any unusual site thrombosis — was reported in eight JAK-STAT inhibitor-treated patients and in one patient on placebo.

The pooled incidence ratios for MACE and VTE were calculated as 0.20 per 100 person exposure years (PEY) for JAK-STAT inhibitor treatment and 0.13 PEY for placebo. The pooled RRs comparing the two treatment groups were a respective 1.13 for MACE and 2.79 for VTE, but neither RR reached statistical significance.

No difference was seen between the treatment arms in terms of treatment emergent adverse events (RR, 1.05), serious adverse events (RR, 0.92), or study discontinuation because of adverse events (RR, 0.94).
 

Reassuring Results?

Dr. Ireland and coauthors said the finding should help to reassure clinicians that the short-term use of JAK-STAT inhibitors in patients with dermatological conditions with low cardiovascular risk profiles “appears to be both safe and well tolerated.” They cautioned, however, that “clinicians must remain judicious” when using these medications for longer periods and in high-risk patient populations.

This was a pragmatic meta-analysis that provides useful information for dermatologists, Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, DC, said in an interview.

“When there are safety concerns, I think that’s where data like this are so important to not just allay the fears of practitioners, but also to arm the practitioner with information for when they discuss a possible treatment with a patient,” said Dr. Friedman, who was not involved in the study.

“What’s unique here is that they’re looking at any possible use of JAK inhibitors for dermatological disease,” so this represents patients that dermatologists would be seeing, he added.

“The limitation here is time, we only can say so much about the safety of the medication with the data that we have,” Dr. Friedman said. Almost 4 months is “a good amount of time” to know about the cardiovascular risks, he said, but added, what happens then? Will the risk increase and will patients need to be switched to another medication?

“There’s no line in the sand,” with regard to using a JAK-STAT inhibitor. “If you look at the label, they’re not meant to be used incrementally,” but as ongoing treatment, while considering the needs of the patient and the relative risks and benefits, he said.

With that in mind, “the open label extension studies for all these [JAK-STAT inhibitors] are really, really important to get a sense of ‘do new signals emerge down the road.’ ”

The meta-analysis received no commercial funding. One author of the work reported personal fees from several pharmaceutical companies which were done outside of analysis. Dr. Friedman has received research funding from or acted as a consultant for several pharmaceutical companies including, Incyte, Pfizer, Eli Lily, and AbbVie.
