Value analysis of JAK inhibitors for RA hampered by limited data
Adequate evidence shows that adding a Janus kinase (JAK) inhibitor to conventional disease-modifying antirheumatic drug therapy provides a net health benefit for patients with rheumatoid arthritis, compared with conventional drugs alone, according to a report by an independent research institute. But the long-term economic value of JAK inhibitors for rheumatoid arthritis is less clear, the report by the Institute for Clinical and Economic Review (ICER) indicates.
ICER on Jan. 9 released a finalized report and policy recommendations on JAK inhibitors and biosimilars for rheumatoid arthritis. The report reviews current evidence for JAK inhibitors for adults with moderately active to severely active rheumatoid arthritis.
Since the nonprofit’s 2017 review of targeted immune modulators for rheumatoid arthritis, two JAK inhibitors, baricitinib (Olumiant) and upadacitinib (Rinvoq), were approved by the Food and Drug Administration. At a December 2019 public meeting of the California Technology Assessment Forum (CTAF), one of ICER’s independent evidence appraisal committees, panelists reviewed recent evidence.
A pricey comparator
In ICER’s analysis, the JAK inhibitor upadacitinib reached common thresholds for cost-effectiveness when compared with adalimumab (Humira). Nevertheless, the 14 members of the independent evidence appraisal committee voted that upadacitinib’s long-term economic value was “low” (8 votes) or “intermediate” (6 votes). Concerns about the generalizability of phase 3 clinical trial data to patients in the real world were among the reservations noted by panelists. Furthermore, “legitimate questions remain about whether or not adalimumab, launched 17 years ago, is fairly priced to begin with,” Pamela Bradt, MD, MPH, ICER’s chief scientific officer, said in a news release.
The panel did not vote on the economic value of tofacitinib (Xeljanz) or baricitinib, the two other JAK inhibitors that are approved for rheumatoid arthritis, because head-to-head evidence against adalimumab was insufficient, ICER said.
“Rheumatoid arthritis is a progressively disabling condition, and patients are fortunate to have multiple therapy options – including biosimilars – that effectively slow disease progression,” Dr. Bradt said. “Many economists might expect medicines to become more affordable in an increasingly crowded therapeutic class; however, because the current rebate structure has erected barriers between patients and several emerging RA therapies, traditional market dynamics have been unable to drive down prices.”
Weighing efficacy and cost
Panelists found that the net health benefit provided by upadacitinib is superior to that provided by adalimumab. At the same time, they said that there is insufficient head-to-head evidence to distinguish between the net health benefit of upadacitinib and tofacitinib or to demonstrate that tofacitinib is superior to adalimumab. Evidence comparing baricitinib to adalimumab does not exist.
CTAF members unanimously agreed that adequate evidence demonstrates that the biosimilar infliximab-dyyb (Inflectra) is clinically equivalent to its reference biologic, infliximab (Remicade).
Economic modeling demonstrated that upadacitinib plus a conventional drug achieves marginally higher quality of life than adalimumab plus a conventional drug does, at similar costs. “Based on this comparison with adalimumab, ICER’s value-based price benchmark range for upadacitinib is between $44,000 and $45,000,” according to the ICER news release. “This benchmark represents a 25% discount off of upadacitinib’s annual list price of $59,860, a suggested discount that is consistent with the rebates we assume the manufacturer is currently offering.”
After the voting session, various experts, including clinicians, patient advocates, and representatives from manufacturers and insurance companies, made the following policy recommendations:
- Regulatory intervention may be needed to ensure that drug prices do not continue to increase further from reasonable alignment with added benefits for patients.
- Insurers, pharmacy benefit managers, and employers should increase transparency around the role of discounts and rebates in formulary design.
- Policymakers should aim to create a system that rewards lower-priced biosimilar treatment options.
The findings of the clinical review by the Institute for Clinical and Economic Review (ICER) are generally in line with our clinical perceptions. We have an increasing number of treatment options for our RA patients, and the results of this review support the efficacy of tofacitinib and upadacitinib, compared with currently available biologic treatments. While ICER’s voting panel did find the data supported the superiority of upadacitinib over adalimumab, the cost analysis notes a WAC (wholesale acquisition cost) for upadacitinib of $59,860. While at expected discounted rates it is felt to be cost effective when compared with adalimumab, it is difficult to know what this means since ICER found adalimumab itself not to be cost effective, compared with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), in its 2017 review.
ICER’s focus is drug pricing and cost effectiveness, so obviously our biologic drugs are in the institute’s crosshairs. This review provided context for a policy roundtable discussion that included patient, payer, and manufacturer input, as well as American College of Rheumatology (ACR) input. We are thankful that ACR had a seat at the table, and thankful ICER is attempting to bring light to the important issues and barriers that perpetuate high drug prices in our marketplace. The discussion was wide ranging but focused on step-edit policies, the role of pharmacy benefit managers (PBMs) in perpetuating high drug prices and the relatively slow uptake of biosimilars in our marketplace.
These issues are critical to every practicing rheumatologist because we each deal daily with the hassles of step-edit/fail-first policies, which hijack our otherwise thoughtful and evidence-based decision making regarding the best treatments for our patients. We know how much (unreimbursed) time it takes our staff to sort through these step edits and prior authorizations, and we have seen recent data regarding how these policies delay care and harm patients. We were thankful to see ICER validate these concerns and note that their suggested guidelines for rational step therapy somewhat mirror those in the Safe Step Act, which ACR supports on a federal legislative level. ACR continues to vigorously support the grandfathering of any patient on an effective treatment, regardless of changes in insurance or formulary; this was an issue of robust debate at their meeting, and this patient-centric position is not uniformly held among policymakers, unfortunately.
ACR agrees with ICER’s conclusion that transparency in the PBM system regarding rebates should be promoted and that opaque rebate negotiations between PBMs and manufacturers both incentivize higher prices and block access to the marketplace for cheaper biosimilar options.
Additionally, ICER and ACR agree about the critical role that biosimilar uptake will play in controlling drug costs. While we do not yet have any biosimilars that have been deemed interchangeable by the Food and Drug Administration, we agree with ICER that data regarding comparable efficacy and safety of biosimilars to their originator products is very reassuring. While the decision to switch to a biosimilar should be an individual decision between a provider and patient, and while we recognize with frustration that many FDA-approved biosimilars are not commercially available because of patent law, it is clear that the current costs of our biologic drugs are not sustainable and the uptake of biosimilars will be critical if we hope our health care economy can continue to support coverage of these life-changing drugs in years to come. We agree with ICER that it is incumbent upon prescribers to reassure our patients regarding the safety and efficacy of these drugs.

Big data breaks down Sjögren’s syndrome
The severity of Sjögren’s syndrome and its organ involvement has direct links to clinical characteristics that include age, gender, ethnicity, and geographical location, according to new research findings from a large, worldwide database of primary Sjögren’s syndrome patients.
Risk factors for more severe disease included male sex, earlier age at diagnosis, black/African-American (BAA) ethnicity, and living in more southerly countries, including below the equator. The authors hailed these factors as potentially helping to predict the presence of systemic disease in newly-diagnosed patients, as well as helping to determine the optimum follow-up strategy.
But not everyone agrees. In interviews, other experts suggested that the data were interesting and valuable, but were not ready to make reliable clinical predictions. “The predictive value of these data are limited when it comes to an individual patient sitting in front of you in the office,” said Tomas Mustelin, MD, professor of medicine at the University of Washington, Seattle.
“It would be an important clinical thing if you can figure out who’s at risk for systemic complications and who isn’t. This is a nice step in that direction,” said Hal Scofield, MD, professor of medicine and pathology at the University of Oklahoma, Oklahoma City, agreeing that the data were too preliminary to be broadly useful because there is too much overlap between different patient groups.
If there is one clinical message, it is that physicians should be looking beyond dry eyes and dry mouth in newly diagnosed Sjögren’s syndrome, according to Sarah Chung, MD, who is an acting instructor of rheumatology at the University of Washington. “It’s a reminder to investigate these extra-glandular manifestations, and a reminder that it is a heterogeneous presentation, so we have to keep an open mind and investigate thoroughly,” she said.
In the research published online in Rheumatology, first author Pilar Brito-Zerón, MD, PhD, of the University of Barcelona Hospital Clínic, and colleagues in the Sjögren Big Data Consortium used European League Against Rheumatism Sjögren’s syndrome disease activity index (ESSDAI) scores to examine phenotype and patient characteristics among 10,007 subjects drawn from the international consortium.
Overall, 93.5% of subjects were women, and the mean age at diagnosis was 53 (standard deviation [SD], 14.1 years). The mean total ESSDAI score was 6.1 (SD, 7.5).
Men had higher mean ESSDAI (8.1 vs. 6.0; P less than .001) and clinical ESSDAI (8.4 vs. 6.1; P less than .001) scores and were more likely to have a high disease activity state (22.5% vs. 11.7%; P less than .001). Domains that scored higher in men included lymphadenopathy (P less than .001), glandular (P less than .001), pulmonary (P = .001), peripheral nervous system (PNS) (P less than .001), and CNS (P less than .001).
The highest global ESSDAI scores were reported in patients younger than 35, but organ dominance differed by age group: The constitutional, lymphadenopathy, glandular, cutaneous, renal, hematologic, and biologic domains were highest in this age group, but pulmonary and peripheral nervous system were highest in patients over 65.
By ethnicity, the highest ESSDAI scores occurred in black/African-American patients (6.7), followed by white (6.5), Asian (5.4), and Hispanic (4.8; P less than .001). The organ-specific domains also tracked by ethnicity, with BAA patients experiencing the highest frequencies of activity in the lymphadenopathy, articular, neurologic, and biologic domains. White patients were more often affected in the glandular, cutaneous, and muscular domains, whereas Asians most often experienced the pulmonary, renal, and hematologic domains, and Hispanics the constitutional domain.
The survey included Europe, America, and Asia, and global ESSDAI scores were higher in the southern countries of Asia and Europe, and higher in countries below the equator in the Americas. The organ-by-organ activity scores had a differentiated pattern between northern and southern locales. Worldwide, the gradient of patients with moderate systemic activity (global ESSDAI score of 5 or higher) at diagnosis followed a north-south gradient.
The study had no specific funding, and the authors have no relevant financial disclosures. Dr. Mustelin, Dr. Scofield, and Dr. Chung have no relevant financial disclosures.

The highest global ESSDAI scores were reported in patients younger than 35, but organ dominance differed by age group: The constitutional, lymphadenopathy, glandular, cutaneous, renal, hematologic, and biologic domains were highest in this age group, but pulmonary and peripheral nervous system were highest in patients over 65.
By ethnicity, the highest ESSDAI scores occurred in black/African-American patients (6.7), followed by white (6.5), Asian (5.4), and Hispanic (4.8; P less than .001). The organ-specific domains also tracked by ethnicity, with BAA patients experiencing the highest frequencies of activity in the lymphadenopathy, articular, neurologic, and biologic domains. White patients were more often affected in the glandular, cutaneous, and muscular domains, whereas Asians most often experienced the pulmonary, renal, and hematologic domains, and Hispanics the constitutional domain.
The survey included Europe, America, and Asia, and global ESSDAI scores were higher in the southern countries of Asia and Europe, and higher in countries below the equator in the Americas. The organ-by-organ activity scores had a differentiated pattern between northern and southern locales. Worldwide, the gradient of patients with moderate systemic activity (global ESSDAI score of 5 or higher) at diagnosis followed a north-south gradient.
The study had no specific funding, and the authors have no relevant financial disclosures. Dr. Mustelin, Dr. Scofield, and Dr. Chung have no relevant financial disclosures.

Cherry concentrate fails for gout flares
Tart cherry concentrate had no impact on gout flares over a 28-day period, based on data from 50 adult patients.
Urate-lowering therapy is part of gout management, and previous studies have suggested that tart cherry concentrate lowers sodium urate within hours in healthy volunteers and to a nonsignificant extent over 120 days in patients with gout, but “the optimal dose of tart cherry concentrate for either a serum urate effect on or flare prevention is unknown,” wrote Lisa K. Stamp, MD, of the University of Otago, Christchurch, New Zealand, and colleagues.
In a study published in Rheumatology, the researchers randomized 50 adults with gout and baseline serum urate levels greater than 0.36 mmol/L (6 mg/dL) to receive one of four doses of tart cherry juice concentrate (7.5 mL, 15 mL, 22.5 mL, or 30 mL) or a placebo twice daily for 28 days. Half of the participants were taking allopurinol and half were not taking any urate-lowering therapy.
After 28 days, patients who received cherry juice showed no significant changes in serum urate regardless of whether they were also taking allopurinol. In addition, cherry juice at any dose had no significant effect on reducing the serum urate area under the curve and no apparent impact on measures including urine urate excretion, change in urinary anthocyanins, and frequency of gout flares, compared with placebo. However, the cherry juice was well tolerated, and 84% of the study participants said they would recommend it to a friend as a method of gout prevention.
The researchers collected blood samples at baseline, and at 1, 3, and 5 hours after consuming cherry juice, and on days 1, 3, 7, 14, 21, and 28. “If there is an effect of cherry concentrate on gout flares over a longer time period, it is not likely to be mediated by reduction in serum urate,” the researchers said.
Of 24 adverse events reported during the study, 18 occurred in patients taking cherry juice at all dosage levels, and one case of hyperglycemia was potentially related to cherry concentrate. No serious adverse events associated with tart cherry concentrate occurred during the study period.
The study findings were limited by several factors including the inability to blind the study because participants prepared their doses at home, and the lack of data on the exact contents of the cherry juice concentrate used in the study, the researchers noted. However, the results suggest that tart cherry concentrate has no effect on serum urate concentration or urinary urate excretion, which make it unlikely to be useful in reducing gout flares, they concluded.
The study was supported by the Health Research Council of New Zealand. The researchers had no financial conflicts to disclose.

Half of SLE patients have incident neuropsychiatric events
Neuropsychiatric events occurred in just over half of all patients recently diagnosed with systemic lupus erythematosus and followed for an average of nearly 8 years in an international study of more than 1,800 patients.
Up to 30% of these neuropsychiatric (NP) events in up to 20% of the followed cohort were directly attributable to systemic lupus erythematosus (SLE) in a representative patient population, wrote John G. Hanly, MD, and associates in Annals of the Rheumatic Diseases. Their findings were consistent with prior reports, they added.
Another notable finding from follow-up of these 1,827 SLE patients was that among those without a history of SLE-related NP events at baseline, 74% remained free of NP events during the subsequent 10 years, wrote Dr. Hanly, professor of medicine and director of the lupus clinic at Dalhousie University, Halifax, N.S., and coauthors. Among patients free from SLE-associated NP events after 2 years, 84% remained event free during their remaining follow-up. SLE patients with a history of an NP event that subsequently resolved had a 72% rate of freedom from another NP event during 10 years of follow-up.
These findings came from patients recently diagnosed with SLE (within the preceding 15 months) and enrolled at any of 31 participating academic medical centers in North America, Europe, and Asia. The investigators considered preenrollment NP events to include those starting from 6 months prior to diagnosis of SLE until the time patients entered the study. They used case definitions for 19 SLE-associated NP events published by the American College of Rheumatology (Arthritis Rheum. 1999 Apr;42[4]:599-608). All enrolled patients underwent annual assessment for NP events, with follow-up continuing as long as 18 years.
The researchers identified NP events in 955 of the 1,827 enrolled patients, a 52% incidence, including 1,910 unique NP events that included episodes from each of the 19 NP event types, with 92% involving the central nervous system and 8% involving the peripheral nervous system. The percentage of NP events attributable to SLE ranged from 17% to 31%, and they occurred in 14%-21% of the studied patients, with the range reflecting various attribution models used in the analyses. Some patients remained in the same NP state, while others progressed through more than one state.
The study did not receive commercial funding. Dr. Hanly had no disclosures.

Gout rates reduced with SGLT2 inhibitors
The incidence of gout was approximately 40% lower in diabetes patients who were prescribed sodium-glucose cotransporter 2 inhibitors (SGLT2) than it was in those who were prescribed glucagonlike peptide–1 receptor (GLP-1) agonists in a population-based new-user cohort study.
Hyperuricemia is a known cause of gout and common in type 2 diabetes patients. SGLT2 inhibitors may reduce the risk of gout by preventing the reabsorption of glucose and lowering serum uric acid levels; however, the impact on gout risk remains uncertain, wrote Michael Fralick, MD, of Brigham and Women’s Hospital, Boston, and colleagues.
In a study published in the Annals of Internal Medicine, the researchers compared SGLT2 inhibitors and GLP-1 agonists in patients with type 2 diabetes to assess protection against gout.
The study population included adults with type 2 diabetes mellitus who had a new prescription for an SGTL2 inhibitor or GLP-1 agonist. The average age of the patients was 54 years; approximately half were women. Baseline characteristics were similar between the groups.
Overall, the researchers found a relative risk reduction of approximately 40% and an absolute risk reduction of approximately three fewer cases per 1,000 person-years in patients who received SGLT2 inhibitors, compared with those who received GLP-1 agonists. The incidence rate for gout in the SGLT2 and GLP-1 groups were 4.9 per 1,000 person-years and 7.8 per 1,000 person-years, respectively.
The study findings were limited by the investigators’ inability to measure potential confounding variables such as body mass index, alcohol use, and high purine diet; incomplete lab data on creatinine and hemoglobin A; and a low baseline risk for gout in the study population, the researchers noted. However, the results persisted across sensitivity analysis and, if replicated, suggest that “SGLT2 inhibitors might be an effective class of medication for the prevention of gout for patients with diabetes or metabolic disorders,” they wrote.
The study was supported in part by Brigham and Women’s Hospital; lead author Dr. Fralick disclosed funding from the Eliot Phillipson Clinician-Scientist Training Program at the University of Toronto and the Canadian Institutes of Health Research.

Draft ACR Takayasu’s guidelines: Surgery is the last resort
ATLANTA – One of the goals in soon-to-be-published Takayasu’s arteritis guidelines from the American College of Rheumatology is to wean patients off high-dose steroids once they are in remission.
This recommendation is in opposition to another option – namely, switching these patients to low-dose glucocorticoids. The idea is to prevent long-term side effects, particularly in children. The guidelines also recommend against escalating immunotherapy for asymptomatic increases in inflammatory markers and generally recommend against surgery – stenting in most cases – unless there is threat to life, limb, or organ and also if limb pain is so severe it cramps quality of life and dose escalation doesn’t get the job done. If surgery is planned, patients should be on perioperative steroids if there’s active disease.
It’s draft guidance for now, but it’s probably what the final document will say when it’s published in 2020, according to a presentation at the annual meeting of the American College of Rheumatology by one of the authors, Anisha Dua, MD, an associate professor of rheumatology at Northwestern University, Chicago. She gave a sneak preview at the meeting.
In general, severe, active Takayasu’s calls for high-dose oral steroids in conjunction with a nonsteroid immunosuppressive, such as methotrexate, azathioprine, leflunomide, or mycophenolate mofetil. There’s evidence that dual therapy gives a more durable remission and also reduces the need for steroids.
When that approach doesn’t do the trick, the next step is a tumor necrosis factor (TNF) inhibitor. There’s evidence for infliximab, adalimumab, certolizumab, and etanercept. Dr. Dua noted, “We still can consider” tocilizumab, but it failed to meet its primary endpoint in a randomized trial, and evidence for other biologics is sparse or nonexistent. “TNF inhibitors are the first line” for refractory disease, Dr. Dua said.
The steroid taper comes after 6-12 months of remission. Given their toxicity, “our goal for steroids is zero,” especially in pediatric populations. Even in remission, patients should have a clinical assessment, including inflammatory markers, every 3-12 months.
A rise in C-reactive protein or erythrocyte sedimentation rate, with no new symptoms, might be a reason for more frequent monitoring, but it’s not a reason to escalate immunosuppression. That should be kept in reserve for new vascular lesions, rapid progression on an old one, or worsening of organ or limb ischemia.
“We recommend [escalation] over surgical intervention” because patients often develop collateral circulation that solves the problem; it also gives the disease time to quiet down should the patient eventually go into surgery. Immediate surgery is reserved for organ or life-threatening disease, Dr. Dua said.
“Takayasu’s is different from other vasculitides in the sense that patients often present with certain nonspecific constitutional symptoms,” and there’s not a lot of pathology or histology to work with, “so we do tend to rely on imaging a lot,” Dr. Dua said.
Angiography has fallen out of favor because it’s invasive and exposes patients to radiation, among other problems. The field has moved to noninvasive imaging such as color Doppler ultrasound, CT angiography, magnetic resonance angiography, and PET CT.
“We do recommend regularly scheduled, noninvasive imaging every 6-12 months, in addition to the routine clinical assessment,” except in children with inactive disease; the risk of sedation outweighs the imaging benefit, Dr. Dua said.
In patients with single-vessel cranial or cervical stenosis, without symptoms, “we recommend medical over surgical management because of the risk of surgery. Surgery can be considered for multivessel involvement,” she said.
She and her colleagues also recommend medical management for renal artery stenosis, including antihypertensives and immunotherapy escalation for active disease. Surgery is considered for refractory hypertension or worsening kidney function

This recommendation is in opposition to another option – namely, switching these patients to low-dose glucocorticoids. The idea is to prevent long-term side effects, particularly in children. The guidelines also recommend against escalating immunotherapy for asymptomatic increases in inflammatory markers and generally recommend against surgery – stenting in most cases – unless there is threat to life, limb, or organ and also if limb pain is so severe it cramps quality of life and dose escalation doesn’t get the job done. If surgery is planned, patients should be on perioperative steroids if there’s active disease.
It’s draft guidance for now, but it’s probably what the final document will say when it’s published in 2020, according to a presentation at the annual meeting of the American College of Rheumatology by one of the authors, Anisha Dua, MD, an associate professor of rheumatology at Northwestern University, Chicago. She gave a sneak preview at the meeting.
In general, severe, active Takayasu’s calls for high-dose oral steroids in conjunction with a nonsteroid immunosuppressive, such as methotrexate, azathioprine, leflunomide, or mycophenolate mofetil. There’s evidence that dual therapy gives a more durable remission and also reduces the need for steroids.
When that approach doesn’t do the trick, the next step is a tumor necrosis factor (TNF) inhibitor. There’s evidence for infliximab, adalimumab, certolizumab, and etanercept. Dr. Dua noted, “We still can consider” tocilizumab, but it failed to meet its primary endpoint in a randomized trial, and evidence for other biologics is sparse or nonexistent. “TNF inhibitors are the first line” for refractory disease, Dr. Dua said.
The steroid taper comes after 6-12 months of remission. Given their toxicity, “our goal for steroids is zero,” especially in pediatric populations. Even in remission, patients should have a clinical assessment, including inflammatory markers, every 3-12 months.
A rise in C-reactive protein or erythrocyte sedimentation rate, with no new symptoms, might be a reason for more frequent monitoring, but it’s not a reason to escalate immunosuppression. That should be kept in reserve for new vascular lesions, rapid progression on an old one, or worsening of organ or limb ischemia.
“We recommend [escalation] over surgical intervention” because patients often develop collateral circulation that solves the problem; it also gives the disease time to quiet down should the patient eventually go into surgery. Immediate surgery is reserved for organ or life-threatening disease, Dr. Dua said.
“Takayasu’s is different from other vasculitides in the sense that patients often present with certain nonspecific constitutional symptoms,” and there’s not a lot of pathology or histology to work with, “so we do tend to rely on imaging a lot,” Dr. Dua said.
Angiography has fallen out of favor because it’s invasive and exposes patients to radiation, among other problems. The field has moved to noninvasive imaging such as color Doppler ultrasound, CT angiography, magnetic resonance angiography, and PET CT.
“We do recommend regularly scheduled, noninvasive imaging every 6-12 months, in addition to the routine clinical assessment,” except in children with inactive disease; the risk of sedation outweighs the imaging benefit, Dr. Dua said.
In patients with single-vessel cranial or cervical stenosis, without symptoms, “we recommend medical over surgical management because of the risk of surgery. Surgery can be considered for multivessel involvement,” she said.
She and her colleagues also recommend medical management for renal artery stenosis, including antihypertensives and immunotherapy escalation for active disease. Surgery is considered for refractory hypertension or worsening kidney function

Prednisolone scores for hand OA
ATLANTA – Dutch investigators at the annual meeting of the American College of Rheumatology made a good case for 6 weeks of low-dose prednisolone to help people with hand osteoarthritis get over a particularly bad spell.
A total of 42 patients randomized to prednisolone 10 mg/day fell a mean of 21.5 mm at 6 weeks from a baseline visual analog hand pain score of 54 mm (out of a possible 100 mm), versus a drop of 5.2 mm from a baseline score of 53 mm among 46 randomized to placebo; the mean group difference was 16.5 mm. Patients taking prednisolone did better on function, quality of life, and physician global assessments, too.
“This trial provides evidence that local inflammation is a suitable target for drug treatment in hand OA. We think this study provides clinicians with a short-term treatment option for patients who have a flare of their disease,” said lead investigator Féline Kroon, MD, a rheumatologist at Leiden (the Netherlands) University Medical Center.
“The large beneficial effect size exceeded that of all available therapeutic options for hand osteoarthritis,” including NSAIDs, she and her team noted in the study write-up, which was published to coincide with the meeting (Lancet. 2019 Nov 30;394[10213]:1993-2001).
Many physicians already use short-course prednisolone for hand OA, but there was no clinical evidence that it helped until now. The study also adds weight to the idea that OA has an inflammatory component – an idea that has been building for a while, Dr. Kroon said.
Leiden investigators and others have previously shown that synovial inflammation is often present in hand OA and a main determinant of pain and radiographic progression.
The 92 patients in the Low-Dose Prednisolone in Patients with Painful Hand Osteoarthritis (HOPE) trial had to have at least four interphalangeal joints (IPJs) with osteoarthritic nodes, at least one IPJ with soft swelling or erythema, and at least one with a positive power Doppler signal or grade 2 or higher synovitis on ultrasound. They also had to have flared at least 20 mm on the pain scale with NSAID washout.
There were more responders in the prednisolone group at 6 weeks (72% versus 33%), and significantly greater improvement in synovial thickening. There was no difference in power Doppler score or synovitis score per joint on MRI, but bone marrow lesions appeared less severe with prednisolone.
All the between-group differences disappeared when prednisolone was tapered after 6 weeks.
Four patients discontinued the study because of an adverse event: a myocardial infarction in the prednisolone group, and, in the control arm, a bowel surgery, an infected leg hematoma, and a case of Lyme arthritis of the knee. Adverse events were otherwise mild and similar in both arms.
The mean age in the study was 64 years, and 79% of the subjects were women. Exclusion criteria included chronic inflammatory rheumatic diseases, psoriasis, use of immune-modulating drugs within 90 days of baseline, and predominantly thumb base pain instead of finger pain.
The approach “is for short course. Long-term steroids can have important side effects, like osteoporosis. We do not think this study should be used to encourage prolonged prescribing of glucocorticoids in patients with hand OA,” Dr. Kroon said.
Two previous trials of glucocorticoids for hand OA were inconclusive. A dose of prednisone 5 mg/day for 4 weeks did not separate from placebo in one, and the second showed pain improvements with a combination of prednisolone and dipyridamole versus placebo, but with more adverse events, particularly dipyridamole headaches.
The work was funded by the Dutch Arthritis Society. Dr. Kroon did not have any disclosures.

Methotrexate gives durable remission from idiopathic granulomatous mastitis
ATLANTA – Methotrexate, in combination with prednisone, might be emerging as the go-to option for idiopathic granulomatous mastitis, according to investigators from Oregon Health & Science University, Portland.
Idiopathic granulomatous mastitis (IGM) is an inflammatory disease in which granulomas form in breast tissue. It strikes mostly young to middle-aged women with painful, firm breast masses, sometimes with redness and drainage. Diagnosis is by biopsy with rule-out of known causes.
IGM does not respond to antibiotics. Prednisone and surgery have been the traditional approaches, but masses can recur after surgery, and a year or more of prednisone, with the weight gain and side effects, is problematic. As a result, cases are increasingly being referred to rheumatologists for other options, said lead investigator Sarah Ringsted, MD, a rheumatology fellow at the university.
A study she presented at the annual meeting of the American College of Rheumatology and previous work from others builds a case for methotrexate, which often seems to put the disease in remission and allows for shorter glucocorticoid courses. These days, “I offer this to patients as a great option. It’s really nice to have, instead of having women go on months and months of high-dose steroids, and I think we can save patients from unnecessary” surgery, Dr. Ringsted said.
Her usual regimen these days is methotrexate 15-20 mg/week for 12-18 months, with high-dose prednisone (greater than 20 mg/day) for the first 3 months, followed by a taper.
Dr. Ringsted and associates compared 23 women treated at the university during 2007-2018. Just 5 of the 12 women (42%) treated with high-dose prednisone alone went into remission and did not relapse over a mean follow-up of 27 months. Two out of three women who had both high-dose glucocorticoids and surgery achieved remission without relapse, as did all three women who received methotrexate and high-dose glucocorticoids (one also had surgery). Five other patients were treated with other options; just two had a durable remission.
The numbers are small, but they add to two previous reports. Among 19 women who had failed other treatments, 94% improved and 75% went into remission with 15 months of methotrexate in a review from Stanford (Calif.) University. An Iranian study of 17 patients treated with methotrexate, and also glucocorticoids in some, had a relapse rate of only 17.8%.
There were several cases of both inflammatory arthritis and erythema nodosum in the Oregon series, a higher incidence than what has been reported before for IGM. “It’s interesting because it makes me think of sarcoidosis. There have been cases of sarcoidosis causing mastitis, but mostly in patients with other features” of the disease. “It makes me wonder if any of these women will develop sarcoidosis later on; I think that’s an interesting question,” Dr. Ringsted said.
Women in the study were an average age of 32 years, and over half were Hispanic, which is associated with a higher risk for IGM. Almost all the women had been pregnant before and had breast fed in the previous 5 years. Cancer, tuberculosis, and fungal infections were among the things ruled out before mastitis was deemed idiopathic.
Women with IGM tend to be of childbearing age, and must be cautioned against the teratogenic effects of methotrexate, Dr. Ringsted noted.
There was no external funding, and the investigators didn’t report any disclosures.

Ideal management of RA in pregnancy improves outcomes
Women whose rheumatoid arthritis is carefully managed before and during pregnancy have a significantly lower risk of adverse pregnancy outcomes, including miscarriage or perinatal death, new research suggests.
A study published in Arthritis Care & Research presents the outcomes of a retrospective, observational study examining health care data from 443 first pregnancies in women with RA and 6,097 women without the disease.
First author Alessandra Bortoluzzi, MD, PhD, from the Rheumatology Unit at the University of Ferrara (Italy) and coauthors looked at seven diagnostic, therapeutic, and follow-up health care quality indicators during the prepregnancy and perinatal period. They included having at least one blood test in the 18 months before conception and during pregnancy, preconception musculoskeletal imaging, no exposure or wash-out from teratogenic drugs, and no exposure to biologic drugs between conception and delivery or end of pregnancy.
An ideal clinical pathway included at least one element from each of the diagnostic, therapeutic, and prenatal follow-up quality indicators.
Overall, women with RA had a significantly higher rate of thyroid diseases, adverse pregnancy outcomes, and miscarriage or perinatal death when compared with controls. However, those who followed the ideal clinical pathway for management of their disease during pregnancy had a 40% lower odds of adverse pregnancy outcomes (odds ratio, 0.60; 95% confidence interval, 0.39-0.94) and a 60% lower odds of miscarriage or perinatal death (OR, 0.40; 95% CI, 0.24-0.69) in comparison with women with RA who were not managed to the same standard. The researchers adjusted both comparisons for age, Charlson comorbidity index, and thyroid diseases.
Women with RA who met diagnostic, therapeutic, and prenatal follow-up quality indicators showed no significant differences from the general population in terms of the risk of adverse pregnancy outcomes, miscarriage, or perinatal death after adjusting for hypertension in addition to the same variables as before.
When researchers looked at some of the individual health care quality indicators, they found that testing for antiphospholipid (aPL) antibodies within 18 months of conception or pregnancy was associated with a 44% lower rate of adverse pregnancy outcomes. Similarly, antinuclear antibody or anti–extractable nuclear antigen antibody testing was associated with 36% lower odds of adverse pregnancy outcomes.
Dr. Bortoluzzi and her coauthors wrote that their findings pointed to the value of testing for aPL antibodies in women with RA who wish to get pregnant.
“In fact, despite the absence of formal recommendation or validated health care quality indicators focused on stratification of preconceptional obstetric risk in patients with RA, we started from the basic and universally accepted assumption that aPL antibodies are pathogenic autoantibodies and therefore recognized risk factors for adverse pregnancy outcome,” they wrote.
Women with RA who had either no exposure to methotrexate or leflunomide or who had a washout period from 6 months prior to conception had 72% lower odds of adverse pregnancy outcomes.
The authors also looked at the effects of drugs such as aspirin, glucocorticoids, and low-molecular-weight heparin that are used during pregnancy. They found that the relative risk of adverse pregnancy outcomes was 40% higher in women with RA who were taking glucocorticoids, compared with those with the disease but not taking that type of medication. However, low-molecular-weight heparin use was associated with an 80% lower relative risk of miscarriage or perinatal death in comparison with those not taking it. Researchers saw no significant effects of aspirin or conventional synthetic disease-modifying antirheumatic drugs on either adverse pregnancy outcomes or the risk of miscarriage or perinatal death.
“This reinforces the importance of adjustment of therapy for RA before conception and throughout pregnancy, because medication use could affect pregnancy course not only influencing maternal disease activity but also the gestational outcome,” the authors wrote. “Although this is a study conducted on administrative data, we can hypothesize that exposure to therapy represents a marker of high RA disease activity and severity. In our setting, it is possible that, the more active the disease, the greater the probability of being included in the ideal clinical pathway, but in any case, this resulted in a lower odds ratio of adverse pregnancy outcome and miscarriage/perinatal death.”
The study was supported by the Italian Society for Rheumatology. No conflicts of interest were declared.

Women whose rheumatoid arthritis is carefully managed before and during pregnancy have a significantly lower risk of adverse pregnancy outcomes, including miscarriage or perinatal death, new research suggests.
A study published in Arthritis Care & Research presents the outcomes of a retrospective, observational study examining health care data from 443 first pregnancies in women with RA and 6,097 women without the disease.
First author Alessandra Bortoluzzi, MD, PhD, from the Rheumatology Unit at the University of Ferrara (Italy) and coauthors looked at seven diagnostic, therapeutic, and follow-up health care quality indicators during the prepregnancy and perinatal period. They included having at least one blood test in the 18 months before conception and during pregnancy, preconception musculoskeletal imaging, no exposure or wash-out from teratogenic drugs, and no exposure to biologic drugs between conception and delivery or end of pregnancy.
An ideal clinical pathway included at least one element from each of the diagnostic, therapeutic, and prenatal follow-up quality indicators.
Overall, women with RA had a significantly higher rate of thyroid diseases, adverse pregnancy outcomes, and miscarriage or perinatal death when compared with controls. However, those who followed the ideal clinical pathway for management of their disease during pregnancy had a 40% lower odds of adverse pregnancy outcomes (odds ratio, 0.60; 95% confidence interval, 0.39-0.94) and a 60% lower odds of miscarriage or perinatal death (OR, 0.40; 95% CI, 0.24-0.69) in comparison with women with RA who were not managed to the same standard. The researchers adjusted both comparisons for age, Charlson comorbidity index, and thyroid diseases.
Women with RA who met diagnostic, therapeutic, and prenatal follow-up quality indicators showed no significant differences from the general population in terms of the risk of adverse pregnancy outcomes, miscarriage, or perinatal death after adjusting for hypertension in addition to the same variables as before.
When researchers looked at some of the individual health care quality indicators, they found that testing for antiphospholipid (aPL) antibodies within 18 months of conception or pregnancy was associated with a 44% lower rate of adverse pregnancy outcomes. Similarly, antinuclear antibody or anti–extractable nuclear antigen antibody testing was associated with 36% lower odds of adverse pregnancy outcomes.
Dr. Bortoluzzi and her coauthors wrote that their findings pointed to the value of testing for aPL antibodies in women with RA who wish to get pregnant.
“In fact, despite the absence of formal recommendation or validated health care quality indicators focused on stratification of preconceptional obstetric risk in patients with RA, we started from the basic and universally accepted assumption that aPL antibodies are pathogenic autoantibodies and therefore recognized risk factors for adverse pregnancy outcome,” they wrote.
Women with RA who had either no exposure to methotrexate or leflunomide or who had a washout period from 6 months prior to conception had 72% lower odds of adverse pregnancy outcomes.
The authors also looked at the effects of drugs such as aspirin, glucocorticoids, and low-molecular-weight heparin that are used during pregnancy. They found that the relative risk of adverse pregnancy outcomes was 40% higher in women with RA who were taking glucocorticoids, compared with those with the disease but not taking that type of medication. However, low-molecular-weight heparin use was associated with an 80% lower relative risk of miscarriage or perinatal death in comparison with those not taking it. Researchers saw no significant effects of aspirin or conventional synthetic disease-modifying antirheumatic drugs on either adverse pregnancy outcomes or the risk of miscarriage or perinatal death.
“This reinforces the importance of adjustment of therapy for RA before conception and throughout pregnancy, because medication use could affect pregnancy course not only influencing maternal disease activity but also the gestational outcome,” the authors wrote. “Although this is a study conducted on administrative data, we can hypothesize that exposure to therapy represents a marker of high RA disease activity and severity.

Down syndrome arthritis: Distinct from JIA and missed in the clinic
ATLANTA – Pediatric Down syndrome arthritis is more aggressive and severe than juvenile idiopathic arthritis (JIA), but it’s underrecognized and undertreated, according to reports at the annual meeting of the American College of Rheumatology.
“The vast majority of parents don’t know their kids are at risk for arthritis,” and a lot of doctors don’t realize it, either. Meanwhile, children show up in the clinic a year or more into the process with irreversible joint damage, said pediatric rheumatologist Jordan Jones, DO, an assistant professor at the University of Missouri, Kansas City, and the lead investigator on a review of 36 children with Down syndrome (DS) in the national Childhood Arthritis and Rheumatology Research Alliance (CARRA) registry.
One solution is to add routine musculoskeletal exams to American Academy of Pediatrics DS guidelines, something Dr. Jones said he and his colleagues are hoping to do.
Part of the problem is that children with DS have a hard time articulating and localizing pain, and it’s easy to attribute functional issues to DS itself. Charlene Foley, MD, PhD, from the National Centre for Paediatric Rheumatology in Dublin, said she’s seen “loads of cases” in which parents were told that their children were acting up, probably because of the DS, when they didn’t want to walk down stairs anymore or hold their parent’s hand.
She was the lead investigator on an Irish program that screened 503 DS children, about one-third of the country’s pediatric DS population, for arthritis; 33 cases were identified, including 18 new ones. Most of the children had polyarticular, rheumatoid factor–negative arthritis, and all of them were antinuclear antibody negative.
A key take-home from the work is that DS arthritis preferentially attacks the hands and wrists and was present exclusively in the hands and wrists of about one-third of the Irish cohort. “So, if you only have a second to examine a child or you can’t get them to sit still, just go straight for the hands, and have a low threshold for imaging,” Dr. Foley said.
DS arthritis is often considered a subtype of JIA, but findings from the studies call that into question and suggest the need for novel therapeutic targets, the investigators said.
The Irish team found that 42% of their subjects (14 of 33) had joint erosions, far more than the 14% of JIA children (3 of 21) who served as controls, and Dr. Foley and colleagues didn’t think that was solely because of delayed diagnosis. Also, at about 20 cases per 1,000, they estimated that arthritis was far more prevalent in DS than was JIA in the general pediatrics population.
Disease onset was at a mean of 7.1 years in Dr. Jones’ CARRA registry review, and mean delay to diagnosis was 11.5 months. The 36 children presented with an average of four affected joints. Only 22% (8 of 36) had elevated inflammatory markers; just one-third were positive for antinuclear antibody, and 17% for human leukocyte antigen B27. It means that “these kids can present with normal labs, even with very aggressive disease. The threshold of concern for arthritis has to be very high when you evaluate these children,” Dr. Jones said.
Treatment was initiated with disease-modifying antirheumatic drugs (DMARDs) in two-thirds of the registry children, often with a concomitant biologic, most commonly etanercept. Over half had at least one switch during a mean follow-up of 4.5 years; methotrexate was a leading culprit, frequently discontinued because of nausea and other problems, and biologics were changed for lack of effect. Active joint counts and physician assessments improved, but there were no significant changes in limited joint counts and health assessments.
In short, “the current therapies for JIA appear to be poorly tolerated, more toxic, and less effective in patients with Down syndrome. These kids don’t respond the same. They have a very high disease burden despite being treated aggressively,” Dr. Jones said.
That finding adds additional weight to the idea that DS arthritis is a distinct disease entity, with unique therapeutic targets. “Down syndrome has a lot of immunologic issues associated with it; maybe that’s it. I think in the next few years, we will be able to show that this is a different disease,” Dr. Jones said.
There was a boost in that direction from benchwork, also led and presented by Dr. Foley, that found significant immunologic, histologic, and genetic differences between JIA and DS arthritis, including lower CD19- and CD20-positive B-cell counts in DS arthritis and higher interferon-gamma and tumor necrosis factor–alpha production, greater synovial lining hyperplasia, and different minor allele frequencies.
There was no industry funding for the studies, and the investigators didn’t have any industry disclosures.
