Test for Preeclampsia Risk in SLE Gives Mixed Results
WASHINGTON — A diagnostic test to predict preeclampsia does not effectively rule in or out this pregnancy complication in women with systemic lupus erythematosus (SLE) and proteinuria, according to new research presented at the annual meeting of the American College of Rheumatology (ACR).
“If you have a patient who has proteinuria during pregnancy, I’m not sure we know what to do with this test,” said Megan Clowse, MD, MPH, associate professor of medicine and chief of the Division of Rheumatology and Immunology at Duke University School of Medicine in Durham, North Carolina. She led the research and presented the work.
The results “are probably a step in the right direction to understanding that we need more biochemical markers for differentiating preeclampsia [in this patient population],” Leanna Wise, MD, of the Keck School of Medicine at the University of Southern California, Los Angeles, said in an interview. She comoderated the session where the research was presented. “It exposed that we have a lot of gray areas in which we need to do more research.”
The test is a ratio of two biomarkers that measure spiral artery and placental health: Soluble fms-like tyrosine kinase 1 (sFlt-1) and placental growth factor (PlGF). In the general population, a sFlt-1/PlGF ratio ≤ 38 effectively rules out the short-term risk for preeclampsia, whereas a ratio ≥ 85 is moderately predictive of preeclampsia. However, it was not known how this test would fare in pregnant women with SLE who are already at a higher risk for the complication.
To answer this question, Clowse and colleagues pulled patient data from an ongoing prospective registry of lupus pregnancies. The analysis included patients with a confirmed SLE diagnosis who had enrolled in the registry prior to 30 weeks’ gestation. All participants had provided a serum sample prior to 16 weeks’ gestation and had singleton pregnancies.
In an extensive chart review, preeclampsia was determined by a roundtable of six experts: Two rheumatologists, two maternal-fetal medicine doctors, and two nephrologists.
The analysis included 79 pregnancies, of which 30% developed preeclampsia. Nearly half (47%) of the participants identified as Black or African American. About 30% had a history of lupus nephritis, and half of these patients had active disease during their pregnancy. About half of the women reported that this was their first pregnancy, and an additional 17% of women reported a prior episode of preeclampsia. Most patients were on aspirin (92%) and hydroxychloroquine (87%), and another 43% were prescribed prednisone and 37% were taking azathioprine.
Researchers assessed whether a low sFlt-1/PlGF ratio (≤ 38) was associated with the absence of preeclampsia at 4- and 8-weeks post–blood draw, as well as during the entire pregnancy. They also tested if a high ratio (≥ 85) was associated with the development of preeclampsia within 4- and 8-weeks post–blood draw and through the entire pregnancy.
Across all pregnancies in the cohort, those with sFlt-1/PlGF ≤ 38 were unlikely to develop preeclampsia at 4 weeks post draw (negative predictive value [NPV], 98%) and 8 weeks post draw (NPV, 96%). Still, 20% of patients with this low ratio went on to develop preeclampsia at some point during their pregnancy.
Similar to the general population, sFlt-1/PlGF ≥ 85 was only moderately predictive of preeclampsia. Over half of all patients with this high ratio developed preeclampsia, but more than 40% did not.
Researchers also stratified patients by urine protein:creatinine ratio (UPCR) at the time of their rheumatology visit, defining proteinuria as a UPCR ≥ 300 mg/g.
In patients without proteinuria (n = 63), a low sFlt-1/PlGF ratio ruled out preeclampsia over the next 8 weeks, but a high sFlt-1/PlGF ratio was not usefully predictive of preeclampsia.
Low Ratio to Rule Out Preeclampsia ‘Reassuring’
The high reliability in ruling out preeclampsia in this subset of patients with a low sFlt-1/PlGF ratio is “reassuring,” Wise said, and suggests that these patients are “relatively safe moving forward,” given regular follow-up.
In the small group of patients with proteinuria (n = 16), 44% ultimately developed preeclampsia. One third of patients with sFlt-1/PlGF ≤ 38 developed preeclampsia in 8 weeks, and half experienced preeclampsia at some point during their pregnancy. Among the patients with sFlt-1:PlGF ≥ 85, 56% developed preeclampsia during their pregnancy.
“The negative predictive values are not really great, and the positive predictive values are not really very useful,” Clowse said. For a pregnant patient with proteinuria, “I don’t think that a high [ratio] is going to tell us that she definitely has preeclampsia today or tomorrow. I also am not convinced yet that a low [ratio] tells us that she’s out of the woods. So, I think we definitely need more research on what to do with this test in patients with proteinuria.”
Clowse is a consultant and has received research support/grants from GSK and UCB. She also reported consulting for AstraZeneca. Wise is a consultant for Aurinia Pharmaceuticals and has received honoraria from AstraZeneca, Aurinia Pharmaceuticals, and GSK.

FROM ACR 2024
Holding RA, SpA Drugs Did Not Improve Antibody Response to COVID Vaccine
WASHINGTON — There is no benefit to interrupting treatment with many of the available targeted synthetic or biologic disease-modifying antirheumatic drugs for rheumatoid arthritis (RA) or spondyloarthritis (SpA) at the time of a repeat COVID-19 vaccine dose, new research found.
In the multicenter, randomized controlled COVID Vaccine Response (COVER) trial of 577 patients with RA or SpA taking either abatacept, Janus kinase (JAK) inhibitors, interleukin (IL)–17 inhibitors, or tumor necrosis factor (TNF) inhibitors, holding those drugs for 2 weeks at the time of COVID-19 vaccination supplemental doses didn’t improve antibody response to the vaccine but did lead to disease flares. Most participants had significant antibody responses to the vaccine, regardless of whether their medication had been held or continued, Jeffrey R. Curtis, MD, the Harbert-Ball Professor of Medicine, Epidemiology, and Computer Science at the University of Alabama at Birmingham, reported at the annual meeting of the American College of Rheumatology (ACR).
Guidelines issued by ACR in 2023 recommended holding abatacept for the COVID vaccine but said that “the task force failed to reach consensus” on whether or not to temporarily interrupt the other medications following primary vaccination or supplemental/booster dosing.
Curtis, who was an author on those guidelines, said in an interview, “to date, we haven’t known whether it might be a good idea to hold certain drugs at the time patients receive their next dose of the COVID vaccine. ... That’s because without direct evidence, you have people trading opinions based on extrapolated data.”
The inability to measure cell-mediated immunity and only humoral (ie, antibody-based) immunity is a limitation in COVER. “Nevertheless, based on what we know now, it isn’t advisable to hold any of the four drug classes that we studied at the time patients receive their next COVID vaccine dose. This finding is in contrast to data from a different trial showing that holding methotrexate for 2 weeks does appear to help in response to COVID-19 vaccination, as well as influenza vaccine,” Curtis said.
Asked to comment, session moderator Elena Myasoedova, MD, PhD, consultant rheumatologist and director of the Inflammatory Arthritis Clinic at the Mayo Clinic, Rochester, Minnesota, said in an interview: “This has been an area of clinical uncertainty. It raises a lot of questions from patients and from physicians alike as to whether or not to hold the medication because the implications are flares, and that’s impactful for patients. Patients care about their RA status and how it is controlled, and if there is no difference, then there is no reason to change the medication regimen.”
To Hold or Not to Hold: COVER Shows It Makes Little Difference to Vaccine Response
In COVER, 128 patients were taking abatacept, 96 IL-17 inhibitors, 237 JAK inhibitors, and 116 TNF inhibitors. The study was conducted within 30 sites of the Excellence Network in Rheumatology, a rheumatology practice–based research network launched in 2021. Participants were identified and enrolled at clinic visits immediately prior to receiving their COVID-19 boosters (in routine settings).
All had previously received two or more doses of the mRNA vaccines made by Pfizer or Moderna. Blood was drawn, and they were randomized 1:1 to either continue or hold their disease medication for 2 weeks following the booster. Blood was collected again at 6 weeks post vaccine.
Anti–receptor-binding domain (RBD) IgG antibody titers increased significantly in all drug categories across both study arms, with no differences between the hold vs continue medication groups, even after adjustments for age, sex, body mass index, methotrexate use, steroid use, and time from booster to measurement. All groups also showed increases in geometric mean fold rise of more than 3%.
Subgroup analyses showed no major differences between antibody responses in the hold vs continue groups. The anti-RBD IgG response was lower for abatacept and JAK inhibitors than for the other two drugs, but there was still no significant benefit to holding them for 2 weeks post vaccination.
Holding Drugs Leads to Disease Flares
On the flip side, there were significant differences between the two groups in their responses to the question: “Did you experience any flare or worsening of your autoimmune disease following your recent COVID-19 booster dose?” Overall, 27% of the hold group responded that they had, compared with just 13% of the continue group (P < .05). This difference was greatest in the JAK inhibitor group (33% vs 9%; P < .05).
Among those reporting flares or worsening disease, both the severity and the duration of the flares were about the same. “Interestingly, the duration is beyond a week for the majority of patients. The reason that’s important is, any symptoms that are so-called flare might simply be reactogenicity symptoms, and that might be confused for flare or disease worsening, but you see that a majority of patients actually have those symptoms extending beyond the week. Most of them are worsening in arthritis, as you might expect,” Curtis said in his presentation.
Asked what they did about the flare, only a minority of patients reported contacting a healthcare provider. In all, 68% of the hold group and 78% of the continue group took no action. That’s good in the sense that most of the flares weren’t severe, but it has implications for research, Curtis pointed out.
“A lot of times in the vaccine literature, people do retrospective chart review by looking to see what the doctor said as to whether the patient had a flare. And what this would tell you is patients may be reporting a lot of flares that their doctor doesn’t know anything about. So if you really want to know whether people are having a flare, even a mild flare, you really have to collect prospective data.”
COVID is Not the Last Pandemic
“These results are reassuring, although I think we need a bit more data on abatacept,” Myasoedova said, adding, “I was also interested in the outcomes, such as severe infections, that actually happened to these patients. What we see in the labs in their immune response is one thing, but then also important is what actually evolves in terms of the outcomes, especially with abatacept.”
Overall, she said, “I think it’s reassuring and definitely informs clinical practice going forward. But then probably we’ll learn more. What we’re hearing is COVID is not the last pandemic.”
The COVER trial receives support from AbbVie, BMS, Eli Lilly, Novartis, and Pfizer. Curtis has received research grants and consulting fees from AbbVie, Amgen, BMS, GSK, Eli Lilly, Novartis, Pfizer, Sanofi, and UCB. Myasoedova has no disclosures.

“These results are reassuring, although I think we need a bit more data on abatacept,” Myasoedova said, adding, “I was also interested in the outcomes, such as severe infections, that actually happened to these patients. What we see in the labs in their immune response is one thing, but then also important is what actually evolves in terms of the outcomes, especially with abatacept.”
Overall, she said, “I think it’s reassuring and definitely informs clinical practice going forward. But then probably we’ll learn more. What we’re hearing is COVID is not the last pandemic.”

Fertility Improved With Treat-to-Target Approach in Rheumatoid Arthritis
WASHINGTON — Women with rheumatoid arthritis (RA) experience improved fertility when treated using a treat-to-target (T2T) approach aimed at remission, according to a new research presented at the annual meeting of the American College of Rheumatology.
In the study, more than half the women following this T2T approach were able to conceive within 3 months, which is “nearly equal to the general population,” said presenter and senior author Radboud Dolhain, MD, PhD, who heads the Department of Rheumatology at Erasmus University Medical Center in Rotterdam, the Netherlands.
Compared with 10%-15% of the general population, as many as 42% of patients with RA are not able to get pregnant within 1 year of unprotected intercourse.
“For people who are thinking about pregnancy or want to plan for pregnancy, talking with them about the importance of making sure their RA is well-treated is an essential aspect,” said Mehret Birru Talabi, MD, PhD, director of the Women’s and Reproductive Health Rheumatology Clinic at the University of Pittsburgh Medical Center in Pennsylvania. She was not involved with the research.
“This is a nice, relatively large study that’s demonstrating [that] if you actually treat the patient and treat them effectively, their time to pregnancy is lower,” she said.
Study Details
The analysis compared time to pregnancy between two cohorts of women with RA who aimed to become pregnant. Women were, on average, around 32 years old in both groups, and nearly 60% had not been pregnant before.
The first cohort was part of the Pregnancy-Induced Amelioration of RA (PARA) study, conducted by Erasmus University Medical Center from 2002 to 2010, in which patients were treated by their own rheumatologists with standard of care at the time. Of the 245 women included, 36% were on no medication, and one fourth were taking nonsteroidal anti-inflammatory drugs (NSAIDs). One third of patients were prescribed sulfasalazine, 6% were on hydroxychloroquine, and 4% were prescribed a tumor necrosis factor (TNF) inhibitor. Of the PARA patients prescribed prednisone, about half used a dose > 7.5 mg/d.
The second cohort was part of the Preconception Counseling in Active RA (PreCARA) study, conducted at Erasmus University Medical Center from 2012 to 2023. PreCARA patients were treated with the T2T approach aimed at remission/low disease activity and avoiding use of NSAIDs and high-dose prednisone (> 7.5 mg/d). Of the 215 women in the cohort, 69% were on sulfasalazine, 65% were on hydroxychloroquine, 53% were taking a TNF inhibitor, 45% took prednisone, and 13% took NSAIDs. For patients prescribed prednisone, 75% used a daily dose ≤ 7.5 mg/d. Only six patients were not taking any medication.
In the preconception period, the median Disease Activity Score in 28 joints using C-reactive protein was 2.33 in the PreCARA cohort and 3.84 in the PARA cohort.
The median time to pregnancy was 84 days in the PreCARA cohort, compared with 196 days in the PARA cohort. Compared with 42% of women in the PARA cohort, less than a quarter of women in the PreCARA cohort did not conceive within 1 year of trying. There was no difference between the two groups in the use of assisted reproductive techniques.
In an additional analysis, Dolhain and colleagues found that time to pregnancy in the PreCARA cohort was most associated with maternal age and nulliparity.
“You also will find [this association] in every cohort in time to pregnancy, and it underscores the robustness of our data,” Dolhain said. “We didn’t find any association [with time to pregnancy] anymore with disease activity, the use of NSAIDs, and the use of prednisone.”
Study ‘Will Make Patients Feel More Confident in Their Decisions’
Discussions about continuing medication before and during pregnancy can be a “tension point” for some patients, Talabi said, and these types of studies provide further evidence to reassure patients that this approach can help them reach their reproductive goals.
The study is “very clinically translatable, where you can show [patients] the benefit of continuing their medications” in the preconception period and during pregnancy, added Catherine Sims, MD, a rheumatologist at Duke Health in Durham, North Carolina, who is focused on reproductive rheumatology and preventive health.
“What we try to drive home is that the health of the mother directly translates to the health of the pregnancy and that includes medications, and that is okay because now we have shown that pregnancies are safe while taking these medications,” she said. “I think [this study] will make patients feel more confident in their decisions, which is a big, important piece of it.”

Gout and SGLT2 Inhibitors: Evidence Points to Reduced Need for ULT, Flare Drugs
WASHINGTON — Use of sodium-glucose cotransporter 2 inhibitors (SGLT2i) reduced the need for urate-lowering therapy (ULT) and gout flare therapies in people who had both type 2 diabetes (T2D) and gout, new research has found.
Data from a large US claims database showed that SGLT2i use was associated with a 31% lower rate of initiation of ULT. “This provides further support for the use of SLGT2i therapy in patients with gout, particularly those with high-risk multimorbidity and polypharmacy,” Greg Challener, MD, a postdoctoral fellow at the Rheumatology and Allergy Clinical Epidemiology Research Center, Massachusetts General Hospital, Boston, said in his presentation of the data at the annual meeting of the American College of Rheumatology.
The first agent of the SGLT2i class, dapagliflozin, was initially approved in the United States a decade ago for treating T2D. Since then, several other “flozins” have become available, and some have also received additional indications for heart failure and albuminuric chronic kidney disease. Several prior studies have linked SGLT2i use with lower rates of gout flares as well as lower likelihood of developing gout in the first place, although not all studies have found this benefit.
Asked about the clinical implications of the new data, Challener said in an interview that “I don’t think we’re quite at the point where this is changing gout management per se, but this just helps us understand that [SGT2is] may have a role at some point, maybe as a combination on top of another agent. Or, in some patients, it really may be enough if they’re already on an SGLT2i where we don’t need to jump to adding allopurinol. Maybe they have tophi, but they were just started on an SGLT2i and they’re not flaring. Typically, you would start those patients on allopurinol, but you could potentially just monitor them if they were just started on one of those [SGLT2i] agents.”
Asked to comment, session moderator J. Antonio Aviña-Zubieta, MD, PhD, head of the Division of Rheumatology at the University of British Columbia, Vancouver, Canada, and senior scientist at Arthritis Research Canada, said in an interview: “What I can see possibly happening when there’s more evidence is that SGLT2is may be used or even become standard of care as an adjuvant therapy to decrease flares, and by that, decrease the risk of complications.”
Reductions in ULT, Flares, and Healthcare Visits
The new study used administrative health data from the multicenter TriNetX Diamond network of electronic medical record and claims data from 92 healthcare sites with 212 million patients. Among those with both T2D and gout who were not taking ULT at baseline, a total of 16,104 initiated SGLT2is and 16,046 initiated glucagon-like peptide 1 receptor agonists (GLP-1 RA).
Propensity score matching was conducted for demographics including age, race, and sex; comorbidities; use of emergency, inpatient, and critical care services; medications; labs; and body mass index. That yielded 11,800 individuals each in the SGLT2i and GLP-1 RA groups.
Over 5 years, 9.9% of the SGLT2i group vs 13.4% of those using GLP-1 RA had initiated ULT, a significant difference with a hazard ratio (HR) of 0.69 (95% CI, 0.64-0.75). The risk for initiation of colchicine for gout flares was 4.7% with SGLT2i vs 6.0% for GLP-1 RA — also a significant difference with an HR of 0.74 (0.65-0.83).
Medical visits for gout occurred in 28.0% vs 28.4% of patients, which also reached statistical significance (HR, 0.94; 95% CI, 0.89-0.99).
Aviña-Zubieta, an author of one of the previous studies finding a reduction in gout flares with SGLT2i, said, “many patients do not want to start gout therapy until they start having more acute attacks. ... So, for a lot of people, it’s a burden taking another pill to prevent one attack. But, if you don’t treat it over time, the attacks come more often. So, can we still delay the initiation of therapy? If you’re not having that many flares, you’re decreasing the burden of the disease and polypharmacy, which I think is the potential benefit in the long run if you already have an indication for the therapy for diabetes. ... These data are supporting that.”
Indeed, Challener said these data can help in counseling patients. “Taking your SGLT2i for your heart failure and your diabetes is also providing some benefit for your gout, and we know that there is also cardiac benefit when gout is controlled.”

Expanded Ultrasound Use in RA, New Technology Spur Updated Guidance
WASHINGTON — After more than a decade, the American College of Rheumatology has developed new draft guidance for the use of musculoskeletal ultrasound (MSUS) to help with diagnosis, monitoring, and prognosis of rheumatoid arthritis (RA). Though not yet finalized, the statements that came out of a first round of committee voting were unveiled at the annual meeting of the American College of Rheumatology (ACR).
The committee was charged with updating the 2012 recommendations on using MSUS in rheumatology clinical practice, explained Veena K. Ranganath, MD, professor of clinical medicine at the University of California, Los Angeles, and director of their Rheumatology Fellowship Musculoskeletal Ultrasound Training Program.
More than 30,000 articles on MSUS and any arthritis have been published since 2012, and there have been significant advances and improvements in technology as well as more widespread education and use in rheumatologic clinical practice, Ranganath said.
“There’s also been advancements in therapeutic agents and therapeutic strategies in use of these medications in rheumatoid arthritis,” Ranganath said. “We all know that the patient of today is very different than the patient of 10 years ago or 20 years ago, so this really impacts the clinical questions we ask of how we need to incorporate musculoskeletal ultrasound into our rheumatology clinical practice.”
The process of developing the guidance involved determining key domains and then relevant clinical questions for ultrasonography using the PICO model (patient/population, intervention, comparison, and outcomes). Evidence came from a review of relevant literature published since 1993 in PubMed, Embase, and the Cochrane Database. A panel of 11 experts voted on the quality of the evidence as being moderate or strong for 33 statements, rejecting three that had no consensus. The committee will hold another round of voting before the guidance is published.
Erin Arnold, MD, a rheumatologist at Arnold Arthritis & Rheumatology in Skokie, Illinois, said in an interview she believes the new guidance will be “tremendously helpful,” particularly in getting “everybody on the same page” with similar practices and helping enhance diagnosis and response to therapy.
Having used MSUS for over 20 years, Arnold said watching it evolve and seeing “this type of manuscript being put together as a resource for physicians who are taking care of inflammatory arthritis is exciting.”
“There’s not a single way we really can assess disease activity in our patients, and so having a composite of things that you’re looking at really enhances our ability to understand people’s pain,” Arnold said.
“When you have a patient in front of you that is in so much pain but doesn’t have any active inflammation, it’s hard to want to further put them at risk with more medication,” she said. “It’s so meaningful to be able to have a conversation about ... what are other complementary interventions? How are they sleeping? How are they eating? What are they taking as far as supplements? What are they doing to decrease that kind of fear and fight-or-flight response that often can drive some of our pain?”
Use of MSUS for Diagnosis Confirmation and Treatment Decisions
Gurjit S. Kaeley, MBBS, professor of medicine, division chief of rheumatology and clinical immunology, and medical director of the Musculoskeletal Ultrasound Program at the University of Florida College of Medicine, Jacksonville, reviewed the final statements for MSUS use with RA.
He said there was strong consensus that adding MSUS to clinical examination can aid diagnosis of early RA in patients with suspected RA, particularly with detection of synovitis, tenosynovitis, and erosions. There was moderate consensus that MSUS detection of tenosynovitis could predict later development of RA.
“Furthermore, erosions do have a predictive prognostic value in telling us that these patients need more attention and more urgent attention to getting urgent care with disease-modifying medications,” Kaeley said. “Ultrasound scanning for bone erosions on a few target joints was found to be feasible in literature and provides information not available with clinical examination. Furthermore, ultrasound is more sensitive than plain radiography for the detection of erosions.”
Moderate consensus supported a cutoff of at least 2 mm for erosions when using MSUS for diagnostic purposes.
Strong consensus supported using MSUS of the wrist, second and third metacarpophalangeal (MCP) joints, and second and third interphalangeal (PIP) joints to aid early RA diagnosis, with moderate consensus that cutoffs of least 2 grayscale (GS) or at least 1 GS with at least 1 power Doppler (PD) at the joint level supports both an RA diagnosis and, in patients already diagnosed with RA, a positive joint.
“Grayscale-only definitions were included since equipment may not have sensitive Doppler,” Kaeley said.
Strong consensus supported scanning only a reduced set of representative or symptomatic joints to monitor disease activity with MSUS.
Inflammatory Signs, Disease Progression, and Flares
There was also strong consensus for using MSUS in patients with established RA and comorbidities to help distinguish between RA-related inflammation versus inflammation from other conditions, such as gout or calcium pyrophosphate deposition disease, or versus non–RA-related pain, such as that from fibromyalgia.
Patients with fibromyalgia, for example, “tend to have more steroid exposure and a high prevalence of biologic use because the composite disease scores tend to overestimate disease activity, especially when compared to ultrasound assessment,” Kaeley said.
Moderate consensus supported using MSUS in patients with established RA to objectively evaluate inflammation so as to eliminate age-related bias.
While MSUS signs of synovitis had only moderate consensus to be associated with radiographic progression and decline in patient-reported outcomes for patients with early RA, consensus was strong for this association in patients with established RA.
In terms of predicting disease progression with MSUS monitoring of RA disease activity, moderate consensus supported scanning the wrists and MCPs and PIPs of the hands and using the dorsal view. Kaeley emphasized that ultrasound is a clinical tool that should be used to answer a clinical question, so the sonographer or clinician needs to provide guidance on the areas to be scanned.
Multiple standardized scoring systems exist for predicting RA disease progression, but there is no consensus on which is the most effective, and there is only moderate consensus about the validity of using dichotomous scoring with an established cutoff for a positive joint.
The combination of MSUS with clinical examination appears to be more effective at confirming RA flares than using only clinical examination, and in certain patients with established RA, MSUS may provide insights into subclinical disease activity to help maintain remission and/or potentially guide treatment decisions, “especially when coming across de-escalation therapy decisions,” Kaeley said.
Despite the negative results of treat-to-target trials that tested MSUS as a routine tool in all patients, the committee achieved strong consensus on the potential value of using MSUS in early RA to clarify clinical status and/or help achieve low disease activity or remission in certain patient populations, “such as those with patient/provider discordance or difficult physical examinations,” Kaeley said.
Therapy Response, Remission, and Shared Decision-Making
Moderate consensus supported acknowledgment that using MSUS to assess response to therapy could be affected by obesity and that MSUS can distinguish active synovitis symptoms from other pain sources in difficult-to-treat RA.
In patients with established RA, the feasibility of scanning the wrists, MCPs, PIPs, and relevant symptomatic joints for remission evaluation received moderate consensus. Meanwhile, strong consensus supported the idea that increasing the number of joints scanned with MSUS could increase the certainty of the patient having achieved remission, though the guidance acknowledges that “this must be balanced against the feasibility within the context of clinical care.”
For confirming RA remission via MSUS, strong consensus supported using GS and PD synovitis and tenosynovitis findings. But consensus was moderate for using the combination of no PD signal and minimal synovial hypertrophy to define ultrasonographic remission and for the use of MSUS detection of subclinical inflammation to predict higher flare rates for those in clinical remission.
The committee moderately agreed that MSUS can enhance patient engagement and understanding of their disease to support personalized treatment decisions, such as adjusting disease-modifying antirheumatic drug regimens.
Finally, the committee broadly agreed that “the integration of musculoskeletal ultrasound presents significant advantages in shared decision-making between healthcare providers and patients,” Kaeley said. “Ultrasound, especially with Doppler technique, provides critical insights into disease activity and structural changes not always apparent during standard examination.”
Arnold said she particularly appreciated that the committee, rather than prescribing a specific exam, opted to be more generalizable so that people use the guidance in the context that makes the most sense for them clinically. She said it’s an incredible tool, without excluding the importance of a patient’s labs and physical examination.
“It’s helped us make diagnoses in patients who were difficult to diagnose. It’s helped us to understand response to therapy or no response to therapy,” she said. “It makes me question all the studies that I see done on medications where they’re not looking at some type of advanced imaging.”
No external funding was noted for the development of the guidance. Ranganath has reported receiving research support from Bristol-Myers Squibb and Mallinckrodt. Kaeley has reported receiving research funding from AbbVie, Bristol-Myers Squibb, Gilead/Galapagos, Janssen, and Novartis. Arnold had no disclosures.

WASHINGTON — After more than a decade, the American College of Rheumatology has developed new draft guidance for the use of musculoskeletal ultrasound (MSUS) to help with diagnosis, monitoring, and prognosis of rheumatoid arthritis (RA). Though not yet finalized, the statements that came out of a first round of committee voting were unveiled at the annual meeting of the American College of Rheumatology (ACR).
The committee was charged with updating the 2012 recommendations on using MSUS in rheumatology clinical practice, explained Veena K. Ranganath, MD, professor of clinical medicine at the University of California, Los Angeles, and director of their Rheumatology Fellowship Musculoskeletal Ultrasound Training Program.
More than 30,000 articles on MSUS and any arthritis have been published since 2012, and there have been significant advances and improvements in technology as well as more widespread education and use in rheumatologic clinical practice, Ranganath said.
“There’s also been advancements in therapeutic agents and therapeutic strategies in use of these medications in rheumatoid arthritis,” Ranganath said. “We all know that the patient of today is very different than the patient of 10 years ago or 20 years ago, so this really impacts the clinical questions we ask of how we need to incorporate musculoskeletal ultrasound into our rheumatology clinical practice.”
The process of developing the guidance involved determining key domains and then relevant clinical questions for ultrasonography using the PICO model (patient/population, intervention, comparison, and outcomes). Evidence came from a review of relevant literature published since 1993 in PubMed, Embase, and the Cochrane Database. A panel of 11 experts voted on the quality of the evidence as being moderate or strong for 33 statements, rejecting three that had no consensus. The committee will hold another round of voting before the guidance is published.
Erin Arnold, MD, a rheumatologist at Arnold Arthritis & Rheumatology in Skokie, Illinois, said in an interview she believes the new guidance will be “tremendously helpful,” particularly in getting “everybody on the same page” with similar practices and helping enhance diagnosis and response to therapy.
Having used MSUS for over 20 years, Arnold said watching it evolve and seeing “this type of manuscript being put together as a resource for physicians who are taking care of inflammatory arthritis is exciting.”
“There’s not a single way we really can assess disease activity in our patients, and so having a composite of things that you’re looking at really enhances our ability to understand people’s pain,” Arnold said.
“When you have a patient in front of you that is in so much pain but doesn’t have any active inflammation, it’s hard to want to further put them at risk with more medication,” she said. “It’s so meaningful to be able to have a conversation about ... what are other complementary interventions? How are they sleeping? How are they eating? What are they taking as far as supplements? What are they doing to decrease that kind of fear and fight-or-flight response that often can drive some of our pain?”
Use of MSUS for Diagnosis Confirmation and Treatment Decisions
Gurjit S. Kaeley, MBBS, professor of medicine, division chief of rheumatology and clinical immunology, and medical director of the Musculoskeletal Ultrasound Program at the University of Florida College of Medicine, Jacksonville, reviewed the final statements for MSUS use with RA.
He said there was strong consensus that adding MSUS to clinical examination can aid diagnosis of early RA in patients with suspected RA, particularly with detection of synovitis, tenosynovitis, and erosions. There was moderate consensus that MSUS detection of tenosynovitis could predict later development of RA.
“Furthermore, erosions do have a predictive prognostic value in telling us that these patients need more attention and more urgent attention to getting urgent care with disease-modifying medications,” Kaeley said. “Ultrasound scanning for bone erosions on a few target joints was found to be feasible in literature and provides information not available with clinical examination.

Need for Low-Dose Steroids to Prevent Relapse in GPA Vasculitis Depends on Treatment Regimen
WASHINGTON — Patients with granulomatosis with polyangiitis (GPA) completely tapered off prednisone have a more than fourfold risk of relapse by 6 months, compared with those tapered to 5 mg/day of prednisone; however, this benefit was only seen in patients not on rituximab, according to new research presented at the annual meeting of the American College of Rheumatology (ACR).
“For patients treated with rituximab, fully tapering off glucocorticoids is reasonable to consider as the first approach,” said Peter Merkel, MD, MPH, chief of the division of rheumatology at the University of Pennsylvania, Philadelphia, during his presentation of the findings.
Although a low dose of glucocorticoids can prevent some minor relapses in patients on other treatment regimens such as methotrexate or azathioprine, “fully tapering off prednisone presents relatively little risk of major relapse, and that major relapse can be treated rather quickly,” Merkel added.
The Assessment of Prednisone in Remission (TAPIR) trial enrolled 143 patients with GPA who were in remission (defined as a Birmingham Vasculitis Activity Score for Wegener’s Granulomatosis [BVAS/WG] of 0) within 1 year of treatment to induce remission for active disease and who were taking 5-10 mg of prednisone per day. After all patients tapered to 5 mg/day of prednisone, 71 patients completely tapered off prednisone over 4 weeks and remained off glucocorticoids until month 6. The remaining patients maintained a 5-mg/day dose over the study period. Placement in either treatment group was randomized, and patients continued other immunosuppressive therapy during the study.
Researchers evaluated the rate of relapse by 6 months, defined as a physician’s decision to increase the dose of glucocorticoids to treat GPA, in both groups.
Across all participants, the median age was 58 years, and 52% of patients were male. Most patients were White, and 47% of all patients were prescribed rituximab.
At 6 months, 15.5% of participants who completely tapered off prednisone experienced a relapse of GPA, compared with 4.2% of those taking low-dose prednisone. Time to relapse was also shorter in the 0-mg prednisone group (P = .026), and relapses occurred continually over 6 months, Merkel said.
When stratified by rituximab use, relapse rates at 6 months between the 5-mg and 0-mg prednisone groups in patients taking rituximab showed no difference. Among patients not taking rituximab, those who completely stopped prednisone were nine and a half times as likely to experience relapse as those in the low-dose group.
Despite these differences in relapse rates, “surprisingly, there were no differences in patient-reported outcomes [such as pain interference, physical function, and fatigue],” Merkel said.
Across all patients, all but one relapse was characterized as minor. There were five serious adverse events and 10 infections in the 0-mg group versus one adverse event and 4 infections in the 5-mg group, but these differences were not statistically significant.
In patients who relapsed, musculoskeletal and ear, nose, and throat manifestations of GPA were most common, and these are “the kind of stuff we see that is helped by low-dose glucocorticoids,” Merkel said.
It’s a good sign that for patients who were completely weaned off glucocorticoids, nearly all relapses were minor, Galina Marder, MD, a rheumatologist and associate professor of medicine at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell, Hempstead, New York, said in an interview. She was not involved with the research.
The study “can reinforce the message [of] trying to get them off steroids completely [when possible],” she said.
The findings also provide insight for future clinical trials, Merkel noted. For patients taking non–rituximab-based regimens, completely tapering off glucocorticoids or maintaining a low dose can affect study outcomes.
“[These data are] even more important for clinical trials because they are [reinforcing] the fact that you can have a diminishing signal if you allow some patients to stay on 5 mg prednisone” when GPA flares are the primary outcome, Marder added.
The Vasculitis Clinical Research Consortium received funding for this research through grants from the National Institutes of Health. Merkel has disclosed financial relationships with AbbVie/Abbott, Amgen, argenx, AstraZeneca, Boehringer Ingelheim, Bristol Myers Squibb, Cabaletta, ChemoCentryx, CSL Behring, Dynacure, Eicos, Electra, EMD Serono, Forbius, Genentech/Roche, Genzyme/Sanofi, GSK, HI-Bio, Inmagene, InflaRx, Janssen, Kiniksa, Kyverna, Magenta, MiroBio, Neutrolis, Novartis, NS Pharma, Pfizer, Regeneron, Sanofi, Sparrow, Takeda, Talaris, UpToDate, and Visterra.

When stratified by rituximab use, relapse rates at 6 months between the 5-mg and 0-mg prednisone groups in patients taking rituximab showed no difference. Among patients not taking rituximab, those who completely stopped prednisone were nine and a half times as likely to experience relapse as those in the low-dose group.
Despite these differences in relapse rates, “surprisingly, there were no differences in patient-reported outcomes [such as pain interference, physical function, and fatigue],” Merkel said.
Across all patients, all but one relapse was characterized as minor. There were five serious adverse events and 10 infections in the 0-mg group versus one adverse event and 4 infections in the 5-mg group, but these differences were not statistically significant.
In patients who relapsed, musculoskeletal and ear, nose, and throat manifestations of GPA were most common, and these are “the kind of stuff we see that is helped by low-dose glucocorticoids,” Merkel said.
It’s a good sign that for patients who were completely weaned off glucocorticoids, nearly all relapses were minor, Galina Marder, MD, a rheumatologist and associate professor of medicine at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell, Hempstead, New York, said in an interview. She was not involved with the research.
The study “can reinforce the message [of] trying to get them off steroids completely [when possible],” she said.
The findings also provide insight for future clinical trials, Merkel noted. For patients taking non–rituximab-based regimens, completely tapering off glucocorticoids or maintaining a low dose can affect study outcomes.
“[These data are] even more important for clinical trials because they are [reinforcing] the fact that you can have a diminishing signal if you allow some patients to stay on 5 mg prednisone” when GPA flares are the primary outcome, Marder added.
The Vasculitis Clinical Research Consortium received funding for this research through grants from the National Institutes of Health. Merkel has disclosed financial relationships with AbbVie/Abbott, Amgen, argenx, AstraZeneca, Boehringer Ingelheim, Bristol Myers Squibb, Cabaletta, ChemoCentryx, CSL Behring, Dynacure, Eicos, Electra, EMD Serono, Forbius, Genentech/Roche, Genzyme/Sanofi, GSK, HI-Bio, Inmagene, InflaRx, Janssen, Kiniksa, Kyverna, Magenta, MiroBio, Neutrolis, Novartis, NS Pharma, Pfizer, Regeneron, Sanofi, Sparrow, Takeda, Talaris, UpToDate, and Visterra.

First Phase 3 Drug Trial in IgG4-Related Disease Has Success
WASHINGTON — The B cell–depleting agent inebilizumab (Uplizna) dramatically reduced the risk of flares and increased year-long remission of IgG4-related disease (RD), new research has found.
In a phase 3, multicenter, double-blind, randomized, placebo-controlled trial of 135 adults with active IgG4-RD, treatment with inebilizumab resulted in a significant 87% reduction in flare risk and nearly fivefold greater likelihood of flare-free remission at 1 year. The results were published online November 14 in The New England Journal of Medicine and were presented at the annual meeting of the American College of Rheumatology (ACR).
The drug’s manufacturer, Amgen, released top-line results of the trial, called MITIGATE, in June 2024.
Until now, the mainstay of management for the chronic multiorgan disease IgG4-RD has been glucocorticoids, which can cause numerous adverse effects. “It is hoped that inebilizumab can be used as an important steroid-sparing medication in this disease to reduce steroid toxicity,” lead author John H. Stone, MD, professor of medicine at Harvard Medical School, Boston, Massachusetts, said in an interview, noting that it may not entirely eliminate the need for steroid treatment, but for many, it appears to work after the remission induction period as a monotherapy without steroids.
Asked to comment, Leonard H. Calabrese, DO, head of the Section of Clinical Immunology and manager of the Clinical Immunology Clinic at the Cleveland Clinic, Ohio, said: “There has been anecdotal or observational evidence for some effect with other immunosuppressive agents, including rituximab, but no robust clinical trial until this study. This clearly has demonstrated efficacy by reducing the risk of flares. And most importantly, putting people into remission means no active disease in any given organ. ... This gives us another tool in the toolbox to attack B cell–directed diseases, and I think it really makes a lot of sense.”
Calabrese cautioned, though, that “this is a disease that extends over many years. This is just a 1-year study. Label extensions will be important.”
And several questions remain, Calabrese noted: “How long do patients need to remain on drug? What will happen when the drug is stopped? Can they be retreated? These are the natural questions that arise in any sentinel study like this. But this is extremely encouraging. And I think it’s great for patients. I also think it’s a clarion call to increase awareness about this disease since there’s now strong evidence of effective treatment.”
Underrecognized, Often Misdiagnosed as Cancer
Indeed, IgG4-RD, a chronic, relapsing, autoimmune, fibro-inflammatory multiorgan disease, was only first described in Japan in 2003. Since then, it has been reported all over the world yet remains vastly underrecognized. It is often misdiagnosed as cancer because it produces lesions in multiple organs. It received an ICD-10 code only about a year ago. A previous study estimated a prevalence of about 5.3 persons per 100,000 but that is likely to be a three- to fourfold underestimate, said Stone, who is also executive chairman of the IgG4ward! Foundation.
“Nobody had heard of the disease until about 20 years ago. ... And there are many people in the world who have still not heard of it despite the fact that it is a multiorgan autoimmune disease and is probably as common, or more common, than many other diseases that rheumatologists spend a lot of time thinking about, such as scleroderma.”
While knowledge about the disease is increasing in rheumatology circles, it’s less well-recognized among many of the specialties where patients present, depending on the location of their lesions. These include gastroenterology, ophthalmology, pulmonary medicine, neurology, and nephrology. “All would be likely to see this disease,” Stone said.
The disease can be mistaken for tumors in many of those locations and even as metastatic cancer, he noted, adding that “any time a patient has a mass lesion in a typical organ, the pancreas, the major salivary glands, the lungs, or the kidneys, this should be on the differential diagnosis.”
The diagnosis of IgG4-RD is a clinical one, involving “quadrangulation between clinical features, serological findings, IgG4 levels in the blood, radiology studies, and then pathology biopsies when those are available,” Stone said.
Calabrese characterized the current situation as “we’re all blind men on the elephant. To the neurologist or the neurosurgeon, it’s a mass in the brain. It could present to the ophthalmologist as an [eye] tumor. It can be thyroid gland failure, pulmonary disease, retroperitoneal fibrosis, hepatobiliary disease, and beyond. So, whoever sees that patient, there’s often a long lag time in recognizing it.”
And interestingly, Stone noted that unlike other autoimmune diseases, IgG4-RD primarily affects middle-aged men rather than younger-to-middle-aged women. And when IgG4-RD is diagnosed, glucocorticoid treatment can be particularly toxic when the pancreas is involved, heightening the risk for hyperglycemia and potentially causing diabetes.
Dramatic Improvement in Flares, Remission Achievement
MITIGATE is a phase 3, multicenter, double-blind, randomized, placebo-controlled trial in which 135 adults (mean age 58.2 years, 88 men) with active IgG4-RD were randomized 1:1 to receive 300-mg intravenous infusions of inebilizumab or placebo on days 1 and 15, and again at week 26. At baseline, 62 (45.9%) participants had newly diagnosed IgG4-RD and 73 (54.1%) had recurrent disease.
Both groups received identical glucocorticoid tapers. Overall, 127 (94.1%) completed the 52 weeks of treatment.
By 52 weeks, only seven patients in the inebilizumab group (10%) had experienced disease flares vs 40 (60%) in the placebo group, a significant difference with a hazard ratio of 0.13 (P < .001).
The percentage of participants achieving flare-free, treatment-free complete remission was 59 with inebilizumab (57%), compared with just 15 (22%) in the placebo group (odds ratio [OR], 4.68; P < .001). And for flare-free, glucocorticoid-free complete remission, those proportions were 40 (59%) vs 15 (22%), respectively (OR, 4.96; P < .001).
Excluding the 8-week glucocorticoid taper period, mean total glucocorticoid use was 1264.2 mg less in the inebilizumab than the placebo group, a significant reduction. Overall, 61 participants (90%) were able to entirely discontinue glucocorticoids during the trial, compared with just 25 (37%) in the placebo group.
Adverse events of grade 3 or higher occurred in 12 participants (18%) in the inebilizumab group and 8 (12%) in the placebo group; serious adverse events occurred in 12 (18%) and 6 (9%), respectively. However, no serious adverse event occurred in more than one participant, and there were no deaths. Adverse events led to withdrawal from the trial in six patients (9%) in the inebilizumab group and three patients (4%) in the placebo group.
Adverse events that occurred in more than 10% of participants in the inebilizumab group were COVID-19 in 16 participants (24%), lymphopenia in 11 (16%), and urinary tract infection in 8 (12%).
Importantly, Stone noted, B-cell depletion can reduce responses to vaccines, so patients should receive all recommended vaccinations, including COVID-19, influenza, respiratory syncytial virus, and others, prior to initiating therapy.
Uplizna (inebilizumab-cdon) was approved by the Food and Drug Administration (FDA) for the treatment of neuromyelitis optica spectrum disorder in 2020. In October 2024, the FDA granted Amgen breakthrough therapy designation for use in IgG4-RD. The company is also developing the drug for use in myasthenia gravis.
The study was funded by Amgen. Stone has reported being a consultant for Amgen, Zenas, Argenx, Bristol Myers Squibb, Novartis, Sanofi, and Horizon Pharma. Calabrese has reported being a consultant and/or speaker for Amgen, AstraZeneca, Jansen, Sanofi, and UCB.

Abuse of the Safety-Net 340B Drug Pricing Program: Why Should Physicians Care?
The 340B Drug Pricing Program began as a noble endeavor, a lifeline designed to help safety-net providers deliver affordable care to America’s most vulnerable populations. However, over the years, this well-intentioned program has strayed from its original purpose, becoming a lucrative space where profits often outweigh patients. Loopholes, lax oversight, and unchecked expansion have allowed some powerful players, such as certain disproportionate share hospitals and their “child sites” as well as for-profit pharmacies, to exploit the system. What was once a program to uplift underserved communities now risks becoming a case study in how good intentions can go astray without accountability.
What exactly is this “340B program” that has captured headlines and the interest of legislatures around the country? What ensures that pharmaceutical manufacturers continue to participate in this program? How lucrative is it? How have underserved populations benefited and how is that measured?
The 340B Drug Pricing Program was established in 1992 under the Public Health Service Act. Its primary goal is to enable covered entities (such as hospitals and clinics serving low-income and uninsured patients) to purchase outpatient drugs from pharmaceutical manufacturers at significantly reduced prices in order to support their care of the low-income and underserved populations. Drug makers are required to participate in this program as a condition of their participation in Medicaid and Medicare Part B and offer these steep discounts to covered entities if they want their medications to be available to 38% of patients nationwide.
The hospitals that make up 78% of the program’s spending are known as disproportionate share hospitals (DSHs). These hospitals must be nonprofit and have at least an 11.75% “disproportionate” share of low-income Medicare or Medicaid inpatients. The other types of non-hospital entities qualifying for 340B pricing are known as initial “federal grantees.” Some examples include federally qualified health centers (FQHC), Ryan White HIV/AIDS program grantees, and other types of specialized clinics, such as hemophilia treatment centers. It needs to be noted up front that it is not these initial non-hospital federal grantees that need more oversight or reform, since according to the Health Resources and Services Administration (HRSA) 2023 report they make up only 22% of all program spending. It is the large, predominantly DSH health systems that are profiting immensely through exponential growth of their clinics and contract pharmacies. However, these health systems have not been able to show exactly who are their eligible patients and how they have been benefiting them.
When the 340B program was established to offer financial relief to hospitals and clinics taking care of the uninsured, it allowed them to save 20%-50% on drug purchases, which could be reinvested in patient care services. It was hoped that savings from the program could be used to provide free or low-cost medications, free vaccines, and other essential health services, essentially allowing safety-net providers to serve their communities despite financial constraints. The initial grantees are fulfilling that mission, but there are concerns regarding DSHs. (See the Coalition of State Rheumatology Organization’s 340B explanatory statement and policy position for more.)
Why Should Independent Practice Physicians Care About This?
Independent doctors should care about the lack of oversight in the 340B program because it affects healthcare costs, patient assistance, market competition, and access to affordable care for underserved and uninsured patients.
It also plays a strong hand in the healthcare consolidation that continues to threaten private physician practices. These acquisitions threaten the viability of independent practices in a variety of specialties across the United States, including rheumatology. HRSA allows 340B-covered entities to register their off-campus outpatient facilities, or child sites, under their 340B designation. Covered entities can acquire drugs at the 340B price, while imposing markups on the reimbursement they submit to private insurance. The additional revenue these covered entities can pocket provides them with a cash flow advantage that physician practices and outpatient clinics will never be able to actualize. This uneven playing field may make rheumatology practices more susceptible to hospital acquisitions. In fact, between 2016 and 2022, large 340B hospitals were responsible for approximately 80% of hospital acquisitions.
Perhaps the most important reason that we should all be concerned about the trajectory of this well-meaning program is that we have seen patients with hospital debt being sued by DSHs who receive 340B discounts so that they can take care of the low-income patients they are suing. We have seen Medicaid patients be turned away from a DSH clinic after being discharged from that hospital, because the hospital had reached its disproportionate share (11.75%) of inpatient Medicare and Medicaid patients. While not illegal, that type of behavior by covered entities is WRONG! Oversight and reform are needed if the 340B program is going to live up to its purpose and not be just another well-intentioned program not fulfilling its mission.
Areas of Concern
There has been controversy regarding the limited oversight of the 340B program by HRSA, leading to abuse of the program. There are deep concerns regarding a lack of transparency in how savings from the program are being used, and there are concerns about the challenges associated with accurate tracking and reporting of 340B discounts, possibly leading to the duplication of discounts for both Medicaid and 340B. For example, a “duplicate discount” occurs if a manufacturer sells medications to a DSH at the 340B price and later pays a Medicaid rebate on the same drug. The extent of duplicate discounts in the 340B program is unknown. However, an audit of 1,536 cases conducted by HRSA between 2012 and 2019 found 429 instances of noncompliance related to duplicate discounts, which is nearly 30% of cases.
DSHs and their contracted pharmacies have been accused of exploiting the program by increasing the number of contract pharmacies and expanding the number of offsite outpatient clinics to maximize profits. As of mid-2024, the number of 340B contract pharmacies, counted by Drug Channels Institute (DCI), numbered 32,883 unique locations. According to DCI, the top five pharmacies in the program happen also to be among the top pharmacy revenue generators and are “for-profit.” They are CVS, Walgreens, Walmart, Express Scripts, and Optum RX. Additionally, a study in JAMA Health Forum showed that, from 2011 to 2019, contract pharmacies in areas with the lowest income decreased by 5.6% while those in the most affluent neighborhoods grew by 5%.
There also has been tremendous growth in the number of covered entities in the 340B program, which grew from just over 8,100 in 2000 to 50,000 in 2020. Before 2004, DSHs made up less than 10% of these entities, but by 2020, they accounted for over 60%. Another study shows that DSHs are expanding their offsite outpatient clinics (“child clinics”) into the affluent neighborhoods serving commercially insured patients who are not low income, to capture the high commercial reimbursements for medications they acquired at steeply discounted prices. This clearly is diverting care away from the intended beneficiaries of the 340B program.
Furthermore, DSHs have been acquiring specialty practices that prescribe some of the most expensive drugs, in order to take advantage of commercial reimbursement for medications that were acquired at the 340B discount price. Independent oncology practices have complained specifically about this happening in their area, where in some cases the DSHs have “stolen” their patients to profit off of the 340B pricing margins. This has the unintended consequence of increasing government spending, according to a study in the New England Journal of Medicine that showed price markups at 340B eligible hospitals were 6.59 times as high as those in independent physician practices after accounting for drug, patient, and geographic factors.
Legal Challenges and Legislation
On May 21, 2024, the US Court of Appeals for the DC Circuit issued a unanimous decision in favor of drug manufacturers, finding that certain manufacturer restrictions on the use of contract pharmacies under the 340B drug pricing program are permissible. The court’s decision follows a lower court (3rd Circuit) ruling which concluded that the 340B statute does not require manufacturers to deliver 340B drugs to an “unlimited number of contract pharmacies.” We’re still awaiting a decision from the 7th Circuit Court on a similar issue. If the 7th Circuit agrees with the government, creating a split decision, there is an increase in the likelihood that the Supreme Court would take up the case.
Johnson & Johnson has also sued the federal government for blocking their proposed use of a rebate model for DSHs that purchase through 340B two of its medications, Stelara and Xarelto, whose maximum fair price was negotiated through the Inflation Reduction Act’s Medicare Drug Price Negotiation Program. J&J states this would ensure that the claims are actually acquired and dispensed by a covered 340B entity, as well as ensuring there are no duplicate discounts as statutorily required by the IRA. When initially proposed, HRSA threatened to remove J&J’s access to Medicare and Medicaid if it pursued this change. J&J’s suit challenges that decision.
However, seven states (Arkansas, Kansas, Louisiana, Minnesota, Missouri, Mississippi, and West Virginia) have been active on this issue, passing laws to prevent manufacturers from limiting contract pharmacies’ ability to acquire 340B-discounted drugs. The model legislation also bans restrictions on the “number, location, ownership, or type of 340B contract pharmacy.”
It should also be noted that there are states that are looking for ways to encourage certain independent private practice specialties (such as gastroenterology and rheumatology) to see Medicaid patients, as well as increase testing for sexually transmitted diseases, by offering the possibility of obtaining 340B pricing in their clinics.
Shifting our focus to Congress, six bipartisan Senators, known as the Group of 6, are working to modernize the 340B program, which hasn’t been updated since the original law in 1992. In 2024, legislation was introduced (see here and here) to reform a number of the features of the 340B drug discount program, including transparency, contract pharmacy requirements, and federal agency oversight.
Who’s Guarding the Hen House?
The Government Accountability Office and the Office of Inspector General over the last 5-10 years have asked HRSA to better define an “eligible” patient, to have more specifics concerning hospital eligibility criteria, and to have better oversight of the program to avoid duplicate discounts. HRSA has said that it doesn’t have the ability or the funding to achieve some of these goals. Consequently, little has been done on any of these fronts, creating frustration among pharmaceutical manufacturers and those calling for more oversight of the program to ensure that eligible patients are receiving the benefit of 340B pricing. Again, these frustrations are not pointed at the initial federally qualified centers or “grantees.”
HRSA now audits 200 covered entities a year, which is less than 2% of entities participating in the 340B program. HRSA expects the 340B entities themselves to have an oversight committee in place to ensure compliance with program requirements.
So essentially, the fox is guarding the hen house?

The 340B Drug Pricing Program began as a noble endeavor, a lifeline designed to help safety-net providers deliver affordable care to America’s most vulnerable populations. However, over the years, this well-intentioned program has strayed from its original purpose, becoming a lucrative space where profits often outweigh patients. Loopholes, lax oversight, and unchecked expansion have allowed some powerful players, such as certain disproportionate share hospitals and their “child sites” as well as for-profit pharmacies, to exploit the system. What was once a program to uplift underserved communities now risks becoming a case study in how good intentions can go astray without accountability.
What exactly is this “340B program” that has captured headlines and the interest of legislatures around the country? What ensures that pharmaceutical manufacturers continue to participate in this program? How lucrative is it? How have underserved populations benefited and how is that measured?
The 340B Drug Pricing Program was established in 1992 under the Public Health Service Act. Its primary goal is to enable covered entities (such as hospitals and clinics serving low-income and uninsured patients) to purchase outpatient drugs from pharmaceutical manufacturers at significantly reduced prices in order to support their care of the low-income and underserved populations. Drug makers are required to participate in this program as a condition of their participation in Medicaid and Medicare Part B and offer these steep discounts to covered entities if they want their medications to be available to 38% of patients nationwide.
The hospitals that make up 78% of the program’s spending are known as disproportionate share hospitals (DSHs). These hospitals must be nonprofit and have at least an 11.75% “disproportionate” share of low-income Medicare or Medicaid inpatients. The other types of non-hospital entities qualifying for 340B pricing are known as initial “federal grantees.” Some examples include federally qualified health centers (FQHC), Ryan White HIV/AIDS program grantees, and other types of specialized clinics, such as hemophilia treatment centers. It needs to be noted up front that it is not these initial non-hospital federal grantees that need more oversight or reform, since according to the Health Resources and Services Administration (HRSA) 2023 report they make up only 22% of all program spending. It is the large, predominantly DSH health systems that are profiting immensely through exponential growth of their clinics and contract pharmacies. However, these health systems have not been able to show exactly who are their eligible patients and how they have been benefiting them.
When the 340B program was established to offer financial relief to hospitals and clinics taking care of the uninsured, it allowed them to save 20%-50% on drug purchases, which could be reinvested in patient care services. It was hoped that savings from the program could be used to provide free or low-cost medications, free vaccines, and other essential health services, essentially allowing safety-net providers to serve their communities despite financial constraints. The initial grantees are fulfilling that mission, but there are concerns regarding DSHs. (See the Coalition of State Rheumatology Organization’s 340B explanatory statement and policy position for more.)
Why Should Independent Practice Physicians Care About This?
Independent doctors should care about the lack of oversight in the 340B program because it affects healthcare costs, patient assistance, market competition, and access to affordable care for underserved and uninsured patients.
It also plays a strong hand in the healthcare consolidation that continues to threaten private physician practices. These acquisitions threaten the viability of independent practices in a variety of specialties across the United States, including rheumatology. HRSA allows 340B-covered entities to register their off-campus outpatient facilities, or child sites, under their 340B designation. Covered entities can acquire drugs at the 340B price, while imposing markups on the reimbursement they submit to private insurance. The additional revenue these covered entities can pocket provides them with a cash flow advantage that physician practices and outpatient clinics will never be able to actualize. This uneven playing field may make rheumatology practices more susceptible to hospital acquisitions. In fact, between 2016 and 2022, large 340B hospitals were responsible for approximately 80% of hospital acquisitions.
Perhaps the most important reason that we should all be concerned about the trajectory of this well-meaning program is that we have seen patients with hospital debt being sued by DSHs who receive 340B discounts so that they can take care of the low-income patients they are suing. We have seen Medicaid patients be turned away from a DSH clinic after being discharged from that hospital, because the hospital had reached its disproportionate share (11.75%) of inpatient Medicare and Medicaid patients. While not illegal, that type of behavior by covered entities is WRONG! Oversight and reform are needed if the 340B program is going to live up to its purpose and not be just another well-intentioned program not fulfilling its mission.
Areas of Concern
There has been controversy regarding the limited oversight of the 340B program by HRSA, leading to abuse of the program. There are deep concerns regarding a lack of transparency in how savings from the program are being used, and there are concerns about the challenges associated with accurate tracking and reporting of 340B discounts, possibly leading to the duplication of discounts for both Medicaid and 340B. For example, a “duplicate discount” occurs if a manufacturer sells medications to a DSH at the 340B price and later pays a Medicaid rebate on the same drug. The extent of duplicate discounts in the 340B program is unknown. However, an audit of 1,536 cases conducted by HRSA between 2012 and 2019 found 429 instances of noncompliance related to duplicate discounts, which is nearly 30% of cases.
DSHs and their contracted pharmacies have been accused of exploiting the program by increasing the number of contract pharmacies and expanding the number of offsite outpatient clinics to maximize profits. As of mid-2024, the number of 340B contract pharmacies, counted by Drug Channels Institute (DCI), numbered 32,883 unique locations. According to DCI, the top five pharmacies in the program happen also to be among the top pharmacy revenue generators and are “for-profit.” They are CVS, Walgreens, Walmart, Express Scripts, and Optum RX.

Late-Onset Axial Spondyloarthritis: How Does It Differ From Early-Onset Disease?
TOPLINE:
METHODOLOGY:
- Researchers conducted a multicenter cross-sectional study including 2165 patients with a clinical diagnosis of axSpA who were identified from the Rheumatic Diseases Portuguese Register from June 2008 to December 2022.
- Patients with symptom onset at or after 45 years of age were referred as late-onset axSpA, whereas those with symptom onset before 45 years as early-onset axSpA.
- Overall, 273 had a diagnosis of late-onset axSpA (mean age at symptom onset, 51.4 years; 55% men) and 1892 had a diagnosis of early-onset axSpA (mean age at symptom onset, 28.9 years; 56% men).
- Independent associations between demographic, clinical, imaging, and treatment characteristics and late-onset axSpA were tested using multivariable logistic regression models.
TAKEAWAY:
- Patients with late-onset axSpA were less likely to be positive for HLA-B27 (51% vs 65%; P < .001) and to have a family history of SpA (8% vs 14%; P < .01), have inflammatory back pain (81% vs 88%; P < .01), and have acute anterior uveitis (13% vs 20%; P < .01) than those with early-onset axSpA.
- Patients with late-onset axSpA had a higher likelihood of having peripheral arthritis than those with early-onset axSpA (36% vs 28%; P < .05).
- The odds of having late-onset axSpA were lower in patients with HLA-B27 positivity (adjusted odds ratio [aOR], 0.6; 95% CI, 0.4-0.7), a family history of SpA (aOR, 0.6; 95% CI, 0.4-0.9), inflammatory back pain (aOR, 0.5; 95% CI, 0.4-0.8), and acute anterior uveitis (aOR, 0.6; 95% CI, 0.4-0.9).
- Conversely, patients with peripheral arthritis had a higher likelihood of developing late-onset axSpA (aOR, 1.5; 95% CI, 1.1-1.9).
IN PRACTICE:
“In this study, we found that [late-onset axSpA] may represent a distinct phenotype with a weaker association with HLA-B27,” the authors wrote. “Whether [late-onset axSpA] comprises a subset of axSpA with a (possibly) different genetic or epigenetic background or rather translates difficulties in recognizing a less typical disease presentation and a population without a genetic marker which can make the diagnostic process more challenging merits further investigation.”

TOPLINE:
METHODOLOGY:
- Researchers conducted a multicenter cross-sectional study including 2165 patients with a clinical diagnosis of axSpA who were identified from the Rheumatic Diseases Portuguese Register from June 2008 to December 2022.
- Patients with symptom onset at or after 45 years of age were referred as late-onset axSpA, whereas those with symptom onset before 45 years as early-onset axSpA.
- Overall, 273 had a diagnosis of late-onset axSpA (mean age at symptom onset, 51.4 years; 55% men) and 1892 had a diagnosis of early-onset axSpA (mean age at symptom onset, 28.9 years; 56% men).
- Independent associations between demographic, clinical, imaging, and treatment characteristics and late-onset axSpA were tested using multivariable logistic regression models.
TAKEAWAY:
- Patients with late-onset axSpA were less likely to be positive for HLA-B27 (51% vs 65%; P < .001) and to have a family history of SpA (8% vs 14%; P < .01), have inflammatory back pain (81% vs 88%; P < .01), and have acute anterior uveitis (13% vs 20%; P < .01) than those with early-onset axSpA.
- Patients with late-onset axSpA had a higher likelihood of having peripheral arthritis than those with early-onset axSpA (36% vs 28%; P < .05).
- The odds of having late-onset axSpA were lower in patients with HLA-B27 positivity (adjusted odds ratio [aOR], 0.6; 95% CI, 0.4-0.7), a family history of SpA (aOR, 0.6; 95% CI, 0.4-0.9), inflammatory back pain (aOR, 0.5; 95% CI, 0.4-0.8), and acute anterior uveitis (aOR, 0.6; 95% CI, 0.4-0.9).
- Conversely, patients with peripheral arthritis had a higher likelihood of developing late-onset axSpA (aOR, 1.5; 95% CI, 1.1-1.9).
IN PRACTICE:
“In this study, we found that [late-onset axSpA] may represent a distinct phenotype with a weaker association with HLA-B27,” the authors wrote. “Whether [late-onset axSpA] comprises a subset of axSpA with a (possibly) different genetic or epigenetic background or rather translates difficulties in recognizing a less typical disease presentation and a population without a genetic marker which can make the diagnostic process more challenging merits further investigation.”

Onset of Rheumatoid Arthritis Presaged by Changes in Gut Microbiome
TOPLINE:
Individuals at an increased risk of developing rheumatoid arthritis (RA) have a unique gut microbial composition, characterized by a notable increase in certain strains of Prevotella bacteria. These changes begin approximately 10 months prior to the onset of RA.
METHODOLOGY:
- In this cross-sectional and longitudinal observational study, researchers aimed to identify microbial associations in the early stages of RA, focusing specifically on Prevotellaceae strains.
- The cross-sectional analysis assessed the gut microbiome profiles of 124 individuals at risk of developing RA, 7 patients with newly diagnosed RA, and 22 healthy control individuals free of musculoskeletal symptoms at five different time points over a period of 15 months; 30 patients progressed to RA during the study period.
- The longitudinal analysis was performed in 19 individuals at risk of developing RA, of whom 5 progressed to the condition.
- The risk of developing RA was identified by the presence of anti–cyclic citrullinated protein (anti-CCP) antibodies and the onset of musculoskeletal pain in the preceding 3 months.
- Gut microbiome taxonomic alterations were investigated using 16S rRNA amplicon sequencing and confirmed with shotgun metagenomic DNA sequencing of 49 samples.
TAKEAWAY:
- Gut microbial diversity, particularly alpha diversity, was notably reduced in CCP+ individuals at risk of developing RA vs healthy control individuals (P = .012). Recognized risk factors for RA development such as the presence of rheumatoid factor antibodies and the human leukocyte antigen shared epitope, were significantly linked to diminished gut microbial diversity, in addition to steroid use.
- A specific Prevotellaceae strain (ASV2058) was found to be overabundant in CCP+ individuals at risk of developing RA and in those newly diagnosed with the condition but not in healthy control individuals. Further analysis showed that enrichment and depletion of three and five strains of Prevotellaceae, respectively, were associated with the progression to RA in CCP+ individuals.
- CCP+ individuals who progressed to RA were found to have substantial fluctuations in gut microbiome profiles around 10 months before clinical diagnosis; however, these profiles were relatively stable 10-15 months before the onset of RA, suggesting that changes in the microbiome occur at a later stage.
- Patients with new-onset RA were found to have distinct metabolic shifts, particularly in pathways related to amino acid and energy metabolism.
IN PRACTICE:
“Individuals at risk of RA harbor a distinctive gut microbial composition, including but not limited to an overabundance of Prevotellaceae species. This microbial signature is consistent and correlates with traditional RA risk factors,” the authors wrote.
SOURCE:
The study was led by Christopher M. Rooney, MD, PhD, University of Leeds in England. It was published online in Annals of the Rheumatic Diseases.
LIMITATIONS:
The small longitudinal sample size and lack of a 1:1 longitudinal comparison between CCP+ individuals at risk for RA and healthy control individuals were major limitations of this study. The new-onset RA cohort was heterogeneous, reflecting the practical constraints of recruitment from standard care clinics. Integrated transcriptomic or metabolomic data were unavailable, restricting interpretation to potential rather than confirmed metabolic activity.
DISCLOSURES:
This study was funded by personal fellowships received by the lead author from Versus Arthritis, Leeds Cares, and a National Institute for Health Research Clinical Lectureship. Some authors disclosed receiving grants, funding, consulting fees, or honoraria from various pharmaceutical companies.
