New guideline offers recommendations for reproductive health in patients with rheumatic diseases
A new guideline from the American College of Rheumatology offers the organization’s first clinical recommendations on how to manage reproductive health issues in patients with rheumatic and musculoskeletal diseases (RMDs).
“With the development of this guideline, the ACR recognizes the key role of clinical rheumatologists not only in managing disease activity but also in understanding the interactions of RMDs and their therapies in the context of reproductive health,” wrote Lisa R. Sammaritano, MD, of Weill Cornell Medicine and the Hospital for Special Surgery in New York, and coauthors. The guideline was published in Arthritis & Rheumatology.
To develop an evidence-based guideline on reproductive health in RMD patients, the researchers embarked on a systematic review of studies in areas like contraception, pregnancy and lactation, assisted reproductive technology (ART), fertility preservation, and hormone therapy. The guideline contains 12 ungraded good practice statements and 131 graded recommendations, all developed through the Grading of Recommendations Assessment, Development, and Evaluation methodology.
In counseling patients about these areas of care, the guideline says that rheumatologists and other clinicians “must collaborate with specialists in the fields of obstetrics-gynecology, maternal-fetal medicine, and reproductive endocrinology and infertility.”
“One thing this guideline does well is highlight the importance of involving maternal-fetal medicine colleagues,” Alison Cahill, MD, a professor in the department of women’s health at the University of Texas at Austin and a maternal-fetal medicine specialist within UT Health Austin’s Women’s Health Institute, said when asked for comment on the guideline. “We’re always very happy to see patients ahead of time who are planning pregnancy to be able to discuss what the care plan would look like. And specifically, to address medications, if required, for their rheumatologic care.
“As we learn more and more,” she added, “we’ve come to understand that most treatments and medications are actually safe or relatively safe to take in pregnancy. Certainly, the benefit of taking them outweighs any small or theoretic risks. On the flip side, the guideline does a nice job of highlighting the importance of good disease control, both at the time of conception and during pregnancy.”
Contraception
In regard to contraception, the guideline strongly recommends the use of effective contraceptives – with a conditional recommendation of IUDs or a subdermal progestin implant – in fertile women with a RMD who have neither systemic lupus erythematosus (SLE) nor positive antiphospholipid antibody (aPL). They also strongly recommend discussing the use of emergency contraception with all RMD patients.
For SLE patients, the guideline strongly recommends the use of effective contraceptives in those with stable or low disease activity who are not positive for aPL. They also strongly recommend progestin‐only or IUD contraceptives over combined estrogen‐progestin contraception. For aPL-positive patients, the guideline strongly recommends against combined estrogen‐progestin contraceptives and for levonorgestrel or copper IUDs or the progestin‐only pill.
Assisted reproductive technology
In regard to ART, the guideline strongly recommends proceeding as needed in aPL-negative women with uncomplicated, stable RMD who are on pregnancy‐compatible medications. They also strongly recommend deferring ART in any RMD patients with moderately or severely active disease.
For aPL-positive patients undergoing ART procedures, they strongly recommend prophylactic anticoagulation with heparin or low-molecular-weight heparin (LMWH) in women with obstetric antiphospholipid syndrome (APS) and therapeutic anticoagulation in women with thrombotic APS. In patients undergoing embryo and oocyte cryopreservation, they strongly recommend continuing immunosuppressive and biologic therapies – the exception being cyclophosphamide (CYC) – for anyone in stable condition.
Fertility preservation
In regard to fertility preservation in patients taking CYC, the guideline strongly suggests sperm cryopreservation as good practice prior to treatment. They also conditionally recommend monthly gonadotropin‐releasing hormone agonist cotherapy in premenopausal women with RMD.
Hormone therapy
In regard to menopause and hormone therapy, the guideline strongly suggests hormone therapy as good practice in postmenopausal women with RMD, without SLE or positive aPL, and who have severe vasomotor symptoms. Hormone therapy is conditionally recommended in patients with SLE, without positive aPL, and with no contraindications. For aPL-positive patients, they strongly recommend against hormone therapy in women with obstetric and/or thrombotic APS.
Pregnancy assessment and management
Among the many recommendations regarding pregnancy assessment and management, the guideline strongly suggests counseling women with RMD who are considering pregnancy to take into account the improved outcomes for pregnant women with low disease activity. They strongly recommend that women considering pregnancy should switch to pregnancy‐compatible medication and pause to assess its efficacy and tolerability before moving forward, along with strongly recommending that pregnant women with active disease initiate or continue a pregnancy‐compatible steroid‐sparing medication. They also recommend testing for anti‐Ro/SS-A and anti‐La/SS-B in women with SLE, Sjögren’s syndrome, systemic sclerosis, or rheumatoid arthritis, but only once and only before or early in the pregnancy.
For women with systemic sclerosis who develop scleroderma renal crisis during pregnancy, the authors strongly advise using ACE inhibitors or angiotensin receptor blockers “because the risk of maternal or fetal death with untreated disease is higher than the risk associated with use of these medications during pregnancy.”
Among women with SLE, the recommendations strongly call for testing either before or early in pregnancy for anticardiolipin antibody, anti–beta2-glycoprotein I, or positive lupus anticoagulant, as well as initiating or continuing hydroxychloroquine (HCQ) if possible. Starting in the first trimester, the authors also conditionally recommend that SLE patients take low-dose aspirin daily
For pregnant women who test positive for aPL but do not meet criteria for obstetric or thrombotic APS, the guideline conditionally recommends prophylactic treatment with low-dose aspirin daily to protect against preeclampsia. When obstetric APS criteria are met, the guideline strongly advises combined treatment with daily low-dose aspirin and prophylactic-dose heparin (or LMWH), as well as prophylactic-dose anticoagulation for 6-12 weeks post partum. When patients have thrombotic APS, this combination treatment should contain heparin dose at a therapeutic level throughout pregnancy and postpartum. However, the authors conditionally recommend against giving low-dose aspirin plus prophylactic-dose heparin to women without obstetric APS. For refractory obstetric APS, the guideline also contains recommendations that are conditionally against treatment with intravenous immunoglobulin or an increased LMWH dose and strongly against adding prednisone to prophylactic-dose heparin or LMWH and low-dose aspirin. In pregnant patients with primary APS, the authors conditionally advise adding HCQ to prophylactic-dose heparin or LMWH and low-dose aspirin therapy. However, women with aPL who do not meet APS criteria or have another indication for HCQ are conditionally advised against prophylactic treatment with the antimalarial.
For women with Anti-Ro/SS-A and/or anti-La/SS-B antibodies in pregnancy, there is conditional advice to use HCQ. When there is no history of an infant with complete heart block or neonatal lupus erythematosus among women with these antibodies, the guideline conditionally advises serial fetal echocardiography (less often than weekly) starting between 16 and 18 weeks and continuing through 26 weeks, but this should be weekly when there is a prior history. Treatment with oral dexamethasone 4 mg daily is conditionally advised when there is echocardiographic evidence of fetal first- or second-degree heart block, but dexamethasone is not recommended when complete heart block is present.
Finally, in regard to medication use, the authors strongly recommend that men who are planning to be fathers continue on HCQ, azathioprine, 6‐mercaptopurine, colchicine, or tumor necrosis factor inhibitors. Conditional treatment recommendations for men planning for pregnancy include methotrexate, mycophenolate mofetil/mycophenolic acid (MMF), leflunomide, sulfasalazine, calcineurin inhibitors, and NSAIDs. They also strongly recommend that this group of men discontinue CYC and thalidomide.
Pregnant women are strongly recommended to discontinue methotrexate, leflunomide (with cholestyramine washout if there are detectable serum levels of its metabolite prior to pregnancy or as soon as it is confirmed), MMF, CYC, and thalidomide within 3 months prior to conception, and they strongly recommend HCQ (in women with SLE), azathioprine/6‐mercaptopurine, colchicine, or sulfasalazine for use throughout pregnancy. They strongly recommend a combination of low‐dose aspirin and prophylactic‐dose heparin for pregnant women with obstetric APS, along with low‐dose aspirin and therapeutic‐dose heparin for women with thrombotic APS throughout pregnancy and postpartum. However, for women with SLE and those who test positive for aPL but do not meet criteria for obstetric or thrombotic APS, the authors conditionally recommend low-dose aspirin starting in the first trimester.
The guideline suggests that women with RMD should be encouraged to breastfeed if they are willing and able; they also suggest that disease control be maintained through lactation‐compatible medications and that the risks and benefits be reviewed on a patient-by-patient basis. Treatment with HCQ, colchicine, sulfasalazine, rituximab, and all tumor necrosis factor inhibitors are strongly recommended as being compatible with breastfeeding, and they strongly recommend against using CYC, leflunomide, MMF, and thalidomide while breastfeeding.
The authors acknowledged the limitations of their guideline, including the literature review being conducted on studies involving adults and an “inability to include recommendations for uncommon but important clinical situations,” including those involving transgender patients and hormonal therapies.
The authors reported numerous potential conflicts of interest, including receiving research support, consulting fees, speaking fees, and honoraria from various pharmaceutical companies.

Secukinumab outperforms adalimumab overall for PsA
MAUI, HAWAII – The interleukin-17A inhibitor secukinumab made a strong showing versus the tumor necrosis factor inhibitor adalimumab for the treatment of psoriatic arthritis in the 52-week, randomized, head-to-head phase 3b EXCEED study, Arthur Kavanaugh, MD, reported at the 2020 Rheumatology Winter Clinical Symposium.
EXCEED was the first double-blind, randomized comparison of an IL-17A inhibitor versus a tumor necrosis factor inhibitor as first-line biologic monotherapy in 853 psoriatic arthritis (PsA) patients with an inadequate response to conventional disease-modifying antirheumatic drugs. And while secukinumab (Cosentyx) narrowly failed to demonstrate superiority over adalimumab (Humira) on the primary endpoint of at least a 20% improvement over baseline on American College of Rheumatology disease criteria at 52 weeks, or ACR20 response, the IL-17A inhibitor demonstrated far greater efficacy for the skin disease, noted Dr. Kavanaugh, a rheumatologist who is professor of medicine at the University of California, San Diego, and RWCS program director. Patients received standard dosing of either drug: secukinumab at 300 mg every 4 weeks or adalimumab at 40 mg every 2 weeks.
Dr. Kavanaugh, an EXCEED coinvestigator, characterized the articular outcomes as similar in the two study arms. The ACR20 primary outcome rate was 67.4% in the secukinumab-treated patients and 61.5% with adalimumab, a difference that didn’t quite reach statistical significance (P = .07). However, in a prespecified secondary analysis of ACR20 rates based upon nonresponder imputation – the most conservative method of statistical analysis, in which all subjects who don’t complete the full study period are counted as treatment failures – secukinumab proved superior to adalimumab by a margin of 66.9% versus 59.5% (P = .02). That result was heavily influenced by the significantly higher dropout rate in the adalimumab group: 23.7%, compared with 14.2% in the secukinumab group.
The ACR50 response rate was 49% in the secukinumab group and 44.6% with adalimumab, a nonsignificant difference. Enthesitis resolution rates at 52 weeks were 60.5% and 54.2%, respectively, also a nonsignificant difference. The mean improvement in Health Assessment Questionnaire–Disability Index scores was closely similar in the two groups. However, a 90% improvement in Psoriasis Area and Severity Index scores, or PASI90 response, was achieved in 65.4% of the secukinumab group, far better than the 43.2% rate with adalimumab.
Dr. Kavanaugh observed that the EXCEED outcomes are consistent with the recently published 24-week results of the SPIRIT-H2H trial, an open-label, assessor-blinded randomized comparison of adalimumab versus another IL-17A inhibitor, ixekizumab (Taltz), in 566 PsA patients. Ixekizumab proved superior to adalimumab for the primary composite endpoint composed of an ACR50 response and simultaneous achievement of a PASI100 response, with rates of 36% and 28%, respectively. The ACR50 rates were similar for the two biologics, while the skin results were superior with ixekizumab.
Eric M. Ruderman, MD, said that, taken together, the EXCEED and SPIRIT-H2H results raise an important issue for clinical practice: Even though both secukinumab and ixekizumab are approved for the treatment of PsA, rheumatologists tend to reflexively reach for a TNF inhibitor as the first biologic in affected patients.
“I don’t know that that necessarily needs to be so. There’s absolutely no reason why an IL-17 inhibitor shouldn’t be equally an option as first-line treatment when you think about starting a biologic in these patients. It’s inertia: We like what we like, we do what we’ve been doing for a long time,” said Dr. Ruderman, professor of medicine and associate chief for clinical affairs in the division of rheumatology at Northwestern University, Chicago.
Indeed, an IL-17A inhibitor may actually be a better first-line option in certain circumstances, such as in the PsA patient with more extensive skin involvement, he continued. Also, there is a possibility that the IL-17A inhibitors are less immunogenic than the anti-TNF biologics, which may result in a more durable response. This concept, while still speculative, is supported by the recently published results of the long-term extension of the phase 3 FUTURE 1 study, in which 82% of patients randomized to secukinumab were still on the biologic after 5 years. That’s a far better retention rate than is seen with TNF inhibitors, he noted.
In addition, SPIRIT-H2H participants randomized to ixekizumab didn’t derive added benefit from concomitant methotrexate, while those on adalimumab did. Thus, PsA patients who desire a simpler, methotrexate-free regimen may prefer an IL-17A inhibitor, Dr. Ruderman said.
Dr. Kavanaugh noted that differences in the side effect profiles of the two classes of biologics may be relevant in treatment decisions. The TNF inhibitors have a higher risk of serious infections than do the IL-17A inhibitors, which in turn are associated with more Candida infections.
Dr. Kavanaugh reported receiving research funding from and serving as a consultant to Novartis, which sponsored EXCEED, as well as more than a dozen other pharmaceutical companies. Dr. Ruderman reported serving as a consultant to Pfizer.

Patients received standard dosing of either drug: secukinumab at 300 mg every 4 weeks or adalimumab at 40 mg every 2 weeks.
Dr. Kavanaugh, an EXCEED coinvestigator, characterized the articular outcomes as similar in the two study arms. The ACR20 primary outcome rate was 67.4% in the secukinumab-treated patients and 61.5% with adalimumab, a difference that didn’t quite reach statistical significance (P = .07). However, in a prespecified secondary analysis of ACR20 rates based upon nonresponder imputation – the most conservative method of statistical analysis, in which all subjects who don’t complete the full study period are counted as treatment failures – secukinumab proved superior to adalimumab by a margin of 66.9% versus 59.5% (P = .02). That result was heavily influenced by the significantly higher dropout rate in the adalimumab group: 23.7%, compared with 14.2% in the secukinumab group.
The ACR50 response rate was 49% in the secukinumab group and 44.6% with adalimumab, a nonsignificant difference. Enthesitis resolution rates at 52 weeks were 60.5% and 54.2%, respectively, also a nonsignificant difference. The mean improvement in Health Assessment Questionnaire–Disability Index scores was closely similar in the two groups. However, a 90% improvement in Psoriasis Area and Severity Index scores, or PASI90 response, was achieved in 65.4% of the secukinumab group, far better than the 43.2% rate with adalimumab.
Dr. Kavanaugh observed that the EXCEED outcomes are consistent with the recently published 24-week results of the SPIRIT-H2H trial, an open-label, assessor-blinded randomized comparison of adalimumab versus another IL-17A inhibitor, ixekizumab (Taltz), in 566 PsA patients. Ixekizumab proved superior to adalimumab for the primary composite endpoint composed of an ACR50 response and simultaneous achievement of a PASI100 response, with rates of 36% and 28%, respectively. The ACR50 rates were similar for the two biologics, while the skin results were superior with ixekizumab.
Eric M. Ruderman, MD, said that, taken together, the EXCEED and SPIRIT-H2H results raise an important issue for clinical practice: Even though both secukinumab and ixekizumab are approved for the treatment of PsA, rheumatologists tend to reflexively reach for a TNF inhibitor as the first biologic in affected patients.
“I don’t know that that necessarily needs to be so. There’s absolutely no reason why an IL-17 inhibitor shouldn’t be equally an option as first-line treatment when you think about starting a biologic in these patients. It’s inertia: We like what we like, we do what we’ve been doing for a long time,” said Dr. Ruderman, professor of medicine and associate chief for clinical affairs in the division of rheumatology at Northwestern University, Chicago.
Indeed, an IL-17A inhibitor may actually be a better first-line option in certain circumstances, such as in the PsA patient with more extensive skin involvement, he continued. Also, there is a possibility that the IL-17A inhibitors are less immunogenic than the anti-TNF biologics, which may result in a more durable response. This concept, while still speculative, is supported by the recently published results of the long-term extension of the phase 3 FUTURE 1 study, in which 82% of patients randomized to secukinumab were still on the biologic after 5 years. That’s a far better retention rate than is seen with TNF inhibitors, he noted.
In addition, SPIRIT-H2H participants randomized to ixekizumab didn’t derive added benefit from concomitant methotrexate, while those on adalimumab did. Thus, PsA patients who desire a simpler, methotrexate-free regimen may prefer an IL-17A inhibitor, Dr. Ruderman said.
Dr. Kavanaugh noted that differences in the side effect profiles of the two classes of biologics may be relevant in treatment decisions. The TNF inhibitors have a higher risk of serious infections than do the IL-17A inhibitors, which in turn are associated with more Candida infections.
Dr. Kavanaugh reported receiving research funding from and serving as a consultant to Novartis, which sponsored EXCEED, as well as more than a dozen other pharmaceutical companies. Dr. Ruderman reported serving as a consultant to Pfizer.
MAUI, HAWAII – The interleukin-17A inhibitor secukinumab made a strong showing versus the tumor necrosis factor inhibitor adalimumab for the treatment of psoriatic arthritis in the 52-week, randomized, head-to-head phase 3b EXCEED study, Arthur Kavanaugh, MD, reported at the 2020 Rheumatology Winter Clinical Symposium.

REPORTING FROM RWCS 2020
Joint replacement: What’s new in 2020
MAUI, HAWAII – Outpatient total hip and knee replacement is “the latest craze” in orthopedic surgery, and it’s being driven by the might of Medicare, William Bugbee, MD, said at the 2020 Rheumatology Winter Clinical Symposium.
“In 2019, Medicare took total knee replacement off the inpatient-only list, meaning you could do it as an outpatient. And just in January 2020, they took total hips off that list. So I have to designate most of my hip and knee replacements as outpatients, even if I do it in the hospital and keep them for 1 night. And some of the private insurers have already gone to that, so they’ll deny coverage if I say I want a 1-day hospital stay, believe it or not,” according to Dr. Bugbee, chief of joint reconstruction in the department of orthopedics at the Scripps Clinic in La Jolla, Calif.
He provided a behind-the-scenes look at contemporary trends in joint replacement as well as tips on how rheumatologists can best help their patients get through the experience with excellent outcomes.
Joint replacement remains the best treatment for advanced arthritis of the hips and knees, he said. There is a high degree of confidence about the predictability and durability of the results. But joint replacement has become highly commoditized.
“We’re getting pummeled by Medicare to make this as cheap as possible,” the orthopedic surgeon explained. “An implant costs the hospital $3,000-$6,000. A care episode for a primary total joint replacement should cost a hospital $8,000-$15,000, which is about what Medicare pays for the [Diagnosis Related Group], so the margins are small. That’s why we’re being drilled on about how much we spend on every little thing. We hardly do any labs, x-rays, anything.”
As a result of recent advances in pre-, peri-, and postoperative management, outpatient joint replacement has become a safe and comparatively economical option for generally healthy patients.
“We’ve engineered a much better patient experience, so the assault and battery of 5, 10, 15 years ago isn’t so bad anymore,” Dr. Bugbee said.
Rheumatologists can expect to see a growing number of their patients undergoing total knee or hip replacement at outpatient surgery centers. That’s not a bad thing so long as the procedure is being done there because the outpatient center employs best practices in order to provide a highly efficient episode of care supported by excellent outcome data, he continued.
State-of-the-art perioperative management in 2020 includes accelerated-care pathways that allow ambulation within an hour or 2 after surgery along with same-day discharge, regional anesthesia with motor-sparing nerve blocks, and multimodal pain management with avoidance of intravenous narcotics except in opioid-tolerant patients. Tranexamic acid is now widely used in order to reduce operative blood loss.
“When I started practice 25 years ago, 50% of patients got a blood transfusion. I haven’t given a blood transfusion to a patient in probably 2 years. Tranexamic acid reduces blood loss by 500-700 cc with no discernible adverse effects. It’s truly remarkable,” he said.
Another important technical advance has been the routine use of oral dexamethasone. “Decadron is an antiemetic, it has anti-inflammatory effects, and it makes people happy. It’s a simple, cheap drug that has revolutionized care,” the surgeon continued.
Postoperative management has been streamlined. Dr. Bugbee is among many orthopedic surgeons who no longer routinely prescribe therapist-directed formal physical therapy for total hip arthroplasty patients, relying instead upon online tools and apps for self-administered physical therapy. Pedal exercise devices available online for $30 or so have been shown to be as effective as supervised physical therapy for knee rehabilitation.
What patients want to know about joint replacement
The question patients most often ask both their referring physician and the orthopedic surgeon is, “How long will my joint replacement last?” The best available data come from a couple of recent paired meta-analyses. The investigators reported 82% implant survivorship 25 years after primary total knee arthroplasty and 70% after unicondylar knee arthroplasty as well as a 25-year implant survivorship rate of 77% for total hip arthroplasty.
“I expected that hip arthroplasty survivorship rate to be much higher than 77%. The reason it’s not is probably because of the metal-on-metal bearing surface debacle of about 10 years ago. There’ve been lots of revisions because of that. We thought metal-on-metal implants were going to be all that, with microscopically low wear, but they turned out to be a nightmare because of metal ion release,” Dr. Bugbee observed.
The long-term joint survivorship data are based upon older implants. Encouraging albeit still preliminary data suggest contemporary implants may last significantly longer. The “clear winner,” he said, is a 36-mm ceramic head and a highly crosslinked polyethylene liner.
“That’s been a game changer, with a 10- to 20-fold decrease in wear compared to plastics for weight-bearing surfaces,” Dr. Bugbee said.
In terms of functional improvement, by various measures 85%-97% of patients are satisfied with the results of their total hip replacement, and 60% report returning to high-level recreational activities. Patient satisfaction scores are lower – 75%-90% – after total knee arthroplasty.
“The total knee replacement just doesn’t work like a regular joint,” the surgeon observed. “When I think of hip and knee replacements, I think of a hip as a Ferrari – it’s a high-performance joint replacement – and I think of the knee as a Ford – it’s serviceable, it does the job, and it’s okay but not fantastic.”
How referring physicians can optimize preoperative management and long-term follow-up
Orthopedic surgeons would appreciate help from rheumatologists and primary care physicians in preoperatively addressing the known modifiable risk factors for poor outcomes of joint replacement. These include obesity, smoking, depression, a hemoglobin A1c of 7% or more, and being on opioids. These risk factors are incompatible with outpatient hip or knee replacement.
“Let the surgeon know if you think outpatient joint replacement is a bad idea in your patient for medical reasons,” Dr. Bugbee urged.
Also, orthopedic surgeons can generally benefit from rheumatologist input regarding perioperative management of patients on standard disease-modifying antirheumatic drugs, biologics, or Janus kinase inhibitors as recommended in the guidelines published jointly by the American College of Rheumatology and the American Association of Hip and Knee Surgeons.
“I can guarantee you that most orthopedic surgeons don’t know about these guidelines. The evidence base for these recommendations is not great, but these are the best guidelines we have,” Dr. Bugbee said.
After joint replacement surgery a patient should get an x-ray of the replacement every 5 years. And if a patient develops a painful hip after arthroplasty, it’s worthwhile to order blood chromium and cobalt levels.
“The implant weight-bearing surface matters. You can’t necessarily tell on x-ray what’s a metal-on-metal hip and what’s metal-on-plastic or ceramic. You already send people for a lot of labs. If you see a patient with a painful total hip replacement, just add a cobalt and chromium. If they’re elevated, talk to the orthopedist,” he advised.
The road ahead
Hip and knee replacement is an $18 billion market today. And it’s a major growth industry: According to a recent projection, there will be 1 million total hip replacements and 4 million total knee replacements annually 10 years from now, figures four times greater than projected for 2030 in an earlier 2005 estimate. The rapid growth is coming from the expanding elderly population combined with a virtual epidemic of posttraumatic arthritis in young people – but decidedly not from patients with joint failure attributable to rheumatoid arthritis.
“Congratulations! You’ve eradicated rheumatoid arthritis from my practice,” Dr. Bugbee declared. “Most of the rheumatoid arthritis patients who come to me come because they have osteoarthritis in their joint, not because of their rheumatoid arthritis.”
He reported serving as a consultant to Orthalign, Insight Medical, and Arthrex, and receiving royalties from Smith and Nephew and Depuy.

Comparison shows tighter treat-to-target approach provides better outcomes in RA
Implementing a more stringent treat‐to‐target strategy could provide better outcomes for patients with early RA, according to a recent comparative study.
The findings confirm the feasibility of adopting a treat‐to‐target approach to ensure optimal outcomes are achieved for patients with early-stage disease.
“The objective of the present study was to compare achievement of remission during 2 years of follow-up in two early RA cohorts implementing different treat‐to‐target strategies,” wrote Vibeke Norvang, MD, of the department of rheumatology at Diakonhjemmet Hospital in Oslo, and colleagues. The findings were published in Arthritis & Rheumatology.
The researchers performed a pooled analysis of data from the randomized ARCTIC trial and the Norwegian Very Early Arthritis Clinic (NOR-VEAC) observational study. The combined cohort included a total of 429 disease-modifying antirheumatic drug (DMARD)–naive early RA patients, 189 and 330 from each study, respectively.
The American College of Rheumatology/European League Against Rheumatism Boolean remission criteria differed between the two cohorts, with more stringent criteria in ARCTIC than in NOR-VEAC. Remission was defined as scores of less than 1.6 and 2.6 on the Disease Activity Scores in 44 joints and 28 joints, respectively.
At 12- and 24-month follow-up, the researchers found that the odds of achieving remission were greater in ARCTIC than in NOR-VEAC (odds ratios, 1.97; 95% confidence interval, 1.21-3.20 vs. OR, 1.82; 95% CI, 1.05-3.16).
“We found that more than half of patients in each cohort had reached the study-specific remission targets at 6 months, and this increased to more than 60% in each cohort at 12 and 24 months,” they reported.
With respect to drug therapy, all study patients started with methotrexate monotherapy at a mean dose of 16.0 mg and 15.5 mg in ARCTIC and NOR-VEAC, respectively. In addition, similar rates of escalation to a biologic DMARD were observed in both studies (25.6% vs. 25.4%) at 24 months.
The researchers acknowledged that a key limitation of the study was comparing outcomes in two cohorts with different study designs; hence, the risk of bias in estimates of effect cannot be excluded.
“Targeting a more stringent remission and implementing more frequent visits provide further potential for favorable outcomes of a treat‐to‐target strategy,” they concluded.
The study was supported by legacy funds provided to the department of rheumatology at Diakonhjemmet Hospital. Three authors reported financial relationships with AbbVie, Amgen, Corrona, Genentech, Janssen, Mylan, Pfizer, and other companies.

Prescription osteoarthritis relief gets OTC approval
The Food and Drug Administration has approved formerly prescription-only Voltaren Arthritis Pain (diclofenac sodium topical gel, 1%) for nonprescription use via a process known as a prescription to over-the-counter (Rx-to-OTC) switch, according to a news release from the agency.
“As a result of the Rx-to-OTC switch process, many products sold over the counter today use ingredients or dosage strengths that were available only by prescription 30 years ago,” Karen Mahoney, MD, acting deputy director of the Office of Nonprescription Drugs in the FDA’s Center for Drug Evaluation and Research, said in the release.
This switch to nonprescription status is usually initiated by the manufacturer, who must provide data that demonstrates the drug in question is both safe and effective as self-medication in accordance with the proposed labeling and that consumers can use it safely and effectively without the supervision of a health care professional.
This particular therapy is a topical NSAID gel and was first approved by the FDA in 2007 with the indication for relief of osteoarthritis pain. It can take 7 days to have an effect, but if patients find it takes longer than that or they need to use it for more than 21 days, they should seek medical attention. The gel can cause severe allergic reactions, especially in people allergic to aspirin; patients who experience such reactions are advised to stop use and seek immediate medical care. Other concerns include potential for liver damage with extended use; the possibility of severe stomach bleeds; and risk of heart attack, heart failure, and stroke.
The gel will no longer be available in prescription form.
Full prescribing information can be found on the FDA website, as can the full news release regarding this approval.

Synovial biopsy findings drive precision medicine for RA closer to the clinic
Researchers are mining the synovium for potential treasure: robust markers to bring precision medicine to the rheumatoid arthritis (RA) arena. The signs, according to a number of recent reports, point toward a gold strike via synovial tissue biopsy.
“I have no doubt about that – I am very confident that this concept of going straight to the tissue and using functional genomics will help us stratify our patients and will be a predictive model for patients with respect to therapy,” Harris R. Perlman, PhD, the Mabel Greene Myers Professor of Medicine and chief of the division of rheumatology at Northwestern University, Chicago, said in an interview.
Dr. Perlman is the principle investigator for the REASON (Rheumatoid Arthritis Synovial Tissue Network) study, and in a 2018 report on the network’s efforts to train participants across the United States in ultrasound-guided joint biopsy techniques and to collect and analyze synovial tissue samples submitted by the six participating centers, he and the coinvestigators explained why a precision approach can’t come soon enough.
“Currently, the standard of care for RA is to prescribe biologic therapy through a costly and time‐consuming trial‐and‐error process. Therefore, the utility of a biomarker to identify how a patient will respond to a particular therapy cannot be overstated,” they wrote (Arthritis Rheumatol. 2018 Jun;70[6]:841-54).
Since that REASON report was published, efforts by the investigators and others, such as those involved with the Accelerating Medicines Partnership (AMP) in RA and Lupus Network, to identify such biomarkers have continued to yield encouraging results.
In fact, data from the phase 4 R4-RA (Response, Relapse and Resistance to Rituximab Therapy in patients with RA) trial – the first randomized, controlled, biopsy-driven trial in RA – were reported in November 2019 at the annual meeting of the American College of Rheumatology. R4-RA demonstrated that patients with B cell–poor RA identified on synovial tissue biopsy (STB) responded better to tocilizumab (Actemra) than to rituximab (Rituxan), whereas those with B cell–rich RA on STB did not, Constantino Pitzalis, MD, head of the Centre for Experimental Medicine & Rheumatology at Queen Mary University of London said, noting that the findings could have “massive implications” for RA management and outcomes.
Numerous treatments exist for RA, but methods for determining which to use for a given patient are sorely lacking and the field of rheumatology lags behind others, like oncology, in bringing individualized medicine to the clinic, he explained.
Why STB?
Despite extensive efforts, blood testing has failed to yield markers sufficient for guiding RA treatment, and although the synovium has long been considered a potentially better source of information to guide treatment given the damage it sustains from RA, biopsies have generally been accessible only during arthroscopic or joint replacement surgery in patients with severe disease, which doesn’t reflect the population of patients who could benefit from early intervention, Dr. Perlman and colleagues explained in their 2018 report.
Musculoskeletal ultrasound (US) technology, however, has advanced dramatically over the past decade, is available and used by rheumatologists in clinical practice, and has brought US-guided joint biopsies to the forefront of research. Such techniques have been used in Europe for years, and as a result, an extensive catalog of literature supports the safety, feasibility, and tolerability of the approach.
A recent study in Portugal by Romao et al., for example, showed “remarkably high” patient tolerability (70%) with 64 US-guided procedures, including 52 in clinical practice and 12 for research purposes. No major adverse events occurred, and biopsy usefulness was high, with 37% having a direct diagnostic impact and with 100% and 95% positive- and negative-predictive values for infection. Further, synovial tissues were retrieved in 88% of biopsies and a median of 75% of samples were gradable (Arthritis Care Res. 2019 Aug 17. doi: 10.1002/acr.24050).
A 2018 study of 524 synovial biopsies, including 402 performed using US-guided needle biopsy, performed at five centers across Europe similarly demonstrated safety and patient tolerability (RMD Open. 2018;4[2]:e000799. doi: 10.1136/mdopen-2018-000799).
Building on the work in Europe, investigators at Northwestern launched the REASON study, assembling a consortium of academic rheumatology groups across the United States, training participants in minimally invasive US-guided joint biopsy techniques, and collecting and analyzing synovial tissue samples submitted by the participating centers.
Laura B. Hughes, MD, a professor at the University of Alabama at Birmingham and an investigator in both the REASON study and AMP, said in an interview that her experience with patients is similar.
“It has been very, very well tolerated,” she said of the biopsy procedure used in the course of the studies – and that’s despite the time and commitment required, she added, explaining that 12 samples, each requiring a separate injection, are obtained over a 30- to 45-minute visit.
“We’ve had no problems, no complications,” she said, also noting the importance of careful patient selection.
Patients are altruistic; they want to be a part of moving things forward and helping other patients, and they have been more than willing to participate, both she and Dr. Perlman noted.
In fact, the REASON study investigators reported that performance of STB by rheumatologists in the United States is feasible and generates high-quality samples.
Further, the transcriptional profiles of isolated RA synovial macrophages identified from samples submitted by Dr. Hughes and others in the network characterized subpopulations of patients and identified six novel transcriptional modules associated with disease activity and therapy, underscoring the potential for precision medicine in RA.
“We posit that transcriptional signatures in macrophages ... will predict responsiveness to specific nonbiologic and/or biologic therapies,” they wrote, adding that future studies will “entail collection of synovial biopsy specimens from a larger cohort longitudinally, prior to, and following therapy.”
The ongoing National Institutes of Health–funded AMP Network research is also using synovial biopsies, but more for identification of molecular pathways with a focus on potential drug development.
A 2019 report from the AMP investigators described their integrated use of single-cell transcriptomics and mass cytometry to reveal cell states expanded in RA synovia and the mapping of inflammatory mediators to their source cell populations, which may be key mediators of RA pathogenesis.
“We observed upregulation of chemokines (CXCL8, CXCL9, and CXCL13), cytokines (IFNG and IL15), and surface receptors (PDGFRB and SMAMF7) in distinct immune and stromal cell populations, suggesting potential novel targets,” they wrote (Nat Immunol. 2019 Jul;20[7]:928-42).
Next steps
These reports, along with the thousands of papers published over the past few decades describing phenotypic and functional abnormalities in synovial tissue obtained from RA patients undergoing joint replacement surgery or, more recently, via STB early in the course of disease, have provided a wealth of information, Helen Michelle McGettrick, MD, noted in an editorial addressing the potential of STB analysis for “unlocking the hidden secrets to personalized medicine.”
The question, however, is whether they have moved the field closer to “translating this discovery science into new biomarkers or drugs to improve diagnosis or prognosis,” she wrote (Arthritis Res Ther. 2019;21[90]. doi: 10.1186/s13075-019-1871-5).
“Three sides of our square are in place: clinical expertise, technology, and patient willingness,” she said, arguing that the fourth side is “standardization in the handling, evaluation, and interpretation of STB.”
In fact, her editorial focused on a joint consensus of the European League Against Rheumatism Synovitis Study Group and the OMERACT Synovial Tissue Biopsy Group (Arthritis Res Ther. 2018;20[265]. doi: 10.1186/s13075-018-1762-1).
The groups, based on member survey responses, proposed a “consensual set of analysis items” to be used for synovial biopsies in clinical practice and translational research, including matters such as biopsy sampling, histologic criteria, and biopsy interpretation. Their work, according to Dr. McGettrick and the authors themselves, marked a step forward, but provided only a foundation for a standardization framework.
One particular area of synovial research that has received recent attention and which illustrates the need for standardization involves the role of synovial B cells in RA. The R4-RA researchers, in conjunction with the Pathobiology of Early Arthritis Cohort, are working to better define the relationship of synovial B cells to clinical RA phenotypes at various disease stages and drug exposures as a potential source of predictive and prognostic biomarkers, and in an article accepted for publication in Arthritis & Rheumatology, they describe a “robust semiquantitative histological B cell score that closely replicates the quantification of B cells by digital or molecular analyses.”
In their study of 329 patients, they demonstrated an ongoing B cell–rich synovitis more prevalent in patients with established RA who had inadequate response to tumor necrosis factor inhibitor therapy than in those with early RA (47.4% vs. 35%), but which does not appear to be captured by standard clinimetric assessment (Arthritis Rheumatol. 2019 Nov 29. doi: 10.1002/art.41184).
“Overall, our study confirms the relevance of synovial B cells in RA and suggests that the classification of patients into B cell–rich/–poor can contribute to patient stratification,” they concluded.
In a related editorial, Dana E. Orange, MD, and Laura T. Donlin, PhD, of the Hospital for Special Surgery, New York, note that previously discrepant findings with respect to the value of B cell infiltrate scores for predicting RA treatment response may relate to the lack of a standardized scoring system (Arthritis Rheumatol. 2019 Nov 29. doi: 10.1002/art.41185).
Together, these emerging findings are “advancing our understanding of the transcriptional and cellular characteristics of the synovium in RA,” they wrote, concluding that incorporation of synovial assessments into clinical management of patients is “the next step in empowering clinicians to apply advances in molecular immunology to better tailor treatment decisions.”
Indeed, an important goal is empowering rheumatologists to become adept in obtaining synovial biopsies in clinical practice, much like gastroenterologists collect tissue for biopsy via colonoscopy, Dr. Pitzalis said in an interview following his R4-RA presentation at the ACR meeting.
Dr. Hughes predicts that a subset will embrace the concept, but not all rheumatologists are interested and not all use musculoskeletal US in their practice.
“It requires a lot of training, there is a credentialing exam, and it’s not necessary for practicing rheumatology, but there is a lot of growth,” she said, noting that training is being promoted through the ACR and other organizations, and Europeans who are well-versed in US-guided STB have served as mentors. “It’s been a nice collaboration, and I think it’s just going to push the field forward ... it really is exciting – I think synovial biopsies will yield a lot of information and really, hopefully, help us target therapy and find new therapeutic targets that we haven’t even thought of.”
However, Dr. Pitzalis stressed that there remains much work to do.
“It’s important to understand this is early data and will require validation in larger and target-driven and biopsy-driven treatment clinical trials,” he said of the R4-RA findings.
Those efforts are underway; the REASON study, for example, is moving forward, having recently been awarded a National Institutes of Health Research Project Grant, Dr. Perlman said, explaining that the latest goal is to determine whether the transcription modules the investigators have identified to date can be predictive of treatment response.
He expects to report outcomes at ACR 2020, and noted that preliminary findings suggest that “we can tell, by 4 weeks, which patients will respond or not.”
Dr. Pitzalis and his colleagues are also working on their “next set of trials,” which are using biopsies for treatment allocation (B cell–poor patients get one drug, B cell–rich patients, another, for example), and he, too said he expects to have additional data to present at ACR 2020.
“If we are to demonstrate clinical utility, I think rheumatology will be ready to implement this methodology in clinical practice,” he said.
The authors interviewed for this article reported having no relevant financial disclosures.

One particular area of synovial research that has received recent attention and which illustrates the need for standardization involves the role of synovial B cells in RA. The R4-RA researchers, in conjunction with the Pathobiology of Early Arthritis Cohort, are working to better define the relationship of synovial B cells to clinical RA phenotypes at various disease stages and drug exposures as a potential source of predictive and prognostic biomarkers, and in an article accepted for publication in Arthritis & Rheumatology, they describe a “robust semiquantitative histological B cell score that closely replicates the quantification of B cells by digital or molecular analyses.”
In their study of 329 patients, they demonstrated an ongoing B cell–rich synovitis more prevalent in patients with established RA who had inadequate response to tumor necrosis factor inhibitor therapy than in those with early RA (47.4% vs. 35%), but which does not appear to be captured by standard clinimetric assessment (Arthritis Rheumatol. 2019 Nov 29. doi: 10.1002/art.41184).
“Overall, our study confirms the relevance of synovial B cells in RA and suggests that the classification of patients into B cell–rich/–poor can contribute to patient stratification,” they concluded.
In a related editorial, Dana E. Orange, MD, and Laura T. Donlin, PhD, of the Hospital for Special Surgery, New York, note that previously discrepant findings with respect to the value of B cell infiltrate scores for predicting RA treatment response may relate to the lack of a standardized scoring system (Arthritis Rheumatol. 2019 Nov 29. doi: 10.1002/art.41185).
Together, these emerging findings are “advancing our understanding of the transcriptional and cellular characteristics of the synovium in RA,” they wrote, concluding that incorporation of synovial assessments into clinical management of patients is “the next step in empowering clinicians to apply advances in molecular immunology to better tailor treatment decisions.”
Indeed, an important goal is empowering rheumatologists to become adept in obtaining synovial biopsies in clinical practice, much like gastroenterologists collect tissue for biopsy via colonoscopy, Dr. Pitzalis said in an interview following his R4-RA presentation at the ACR meeting.
Dr. Hughes predicts that a subset will embrace the concept, but not all rheumatologists are interested and not all use musculoskeletal US in their practice.
“It requires a lot of training, there is a credentialing exam, and it’s not necessary for practicing rheumatology, but there is a lot of growth,” she said, noting that training is being promoted through the ACR and other organizations, and Europeans who are well-versed in US-guided STB have served as mentors. “It’s been a nice collaboration, and I think it’s just going to push the field forward ... it really is exciting – I think synovial biopsies will yield a lot of information and really, hopefully, help us target therapy and find new therapeutic targets that we haven’t even thought of.”
However, Dr. Pitzalis stressed that there remains much work to do.
“It’s important to understand this is early data and will require validation in larger and target-driven and biopsy-driven treatment clinical trials,” he said of the R4-RA findings.
Those efforts are underway; the REASON study, for example, is moving forward, having recently been awarded a National Institutes of Health Research Project Grant, Dr. Perlman said, explaining that the latest goal is to determine whether the transcription modules the investigators have identified to date can be predictive of treatment response.
He expects to report outcomes at ACR 2020, and noted that preliminary findings suggest that “we can tell, by 4 weeks, which patients will respond or not.”
Dr. Pitzalis and his colleagues are also working on their “next set of trials,” which are using biopsies for treatment allocation (B cell–poor patients get one drug, B cell–rich patients, another, for example), and he, too said he expects to have additional data to present at ACR 2020.
“If we are to demonstrate clinical utility, I think rheumatology will be ready to implement this methodology in clinical practice,” he said.
The authors interviewed for this article reported having no relevant financial disclosures.
Researchers are mining the synovium for potential treasure: robust markers to bring precision medicine to the rheumatoid arthritis (RA) arena. The signs, according to a number of recent reports, point toward a gold strike via synovial tissue biopsy.
“I have no doubt about that – I am very confident that this concept of going straight to the tissue and using functional genomics will help us stratify our patients and will be a predictive model for patients with respect to therapy,” Harris R. Perlman, PhD, the Mabel Greene Myers Professor of Medicine and chief of the division of rheumatology at Northwestern University, Chicago, said in an interview.
Dr. Perlman is the principle investigator for the REASON (Rheumatoid Arthritis Synovial Tissue Network) study, and in a 2018 report on the network’s efforts to train participants across the United States in ultrasound-guided joint biopsy techniques and to collect and analyze synovial tissue samples submitted by the six participating centers, he and the coinvestigators explained why a precision approach can’t come soon enough.
“Currently, the standard of care for RA is to prescribe biologic therapy through a costly and time‐consuming trial‐and‐error process. Therefore, the utility of a biomarker to identify how a patient will respond to a particular therapy cannot be overstated,” they wrote (Arthritis Rheumatol. 2018 Jun;70[6]:841-54).
Since that REASON report was published, efforts by the investigators and others, such as those involved with the Accelerating Medicines Partnership (AMP) in RA and Lupus Network, to identify such biomarkers have continued to yield encouraging results.
In fact, data from the phase 4 R4-RA (Response, Relapse and Resistance to Rituximab Therapy in patients with RA) trial – the first randomized, controlled, biopsy-driven trial in RA – were reported in November 2019 at the annual meeting of the American College of Rheumatology. R4-RA demonstrated that patients with B cell–poor RA identified on synovial tissue biopsy (STB) responded better to tocilizumab (Actemra) than to rituximab (Rituxan), whereas those with B cell–rich RA on STB did not, Constantino Pitzalis, MD, head of the Centre for Experimental Medicine & Rheumatology at Queen Mary University of London said, noting that the findings could have “massive implications” for RA management and outcomes.
Numerous treatments exist for RA, but methods for determining which to use for a given patient are sorely lacking and the field of rheumatology lags behind others, like oncology, in bringing individualized medicine to the clinic, he explained.
Why STB?
Despite extensive efforts, blood testing has failed to yield markers sufficient for guiding RA treatment, and although the synovium has long been considered a potentially better source of information to guide treatment given the damage it sustains from RA, biopsies have generally been accessible only during arthroscopic or joint replacement surgery in patients with severe disease, which doesn’t reflect the population of patients who could benefit from early intervention, Dr. Perlman and colleagues explained in their 2018 report.
Musculoskeletal ultrasound (US) technology, however, has advanced dramatically over the past decade, is available and used by rheumatologists in clinical practice, and has brought US-guided joint biopsies to the forefront of research. Such techniques have been used in Europe for years, and as a result, an extensive catalog of literature supports the safety, feasibility, and tolerability of the approach.
A recent study in Portugal by Romao et al., for example, showed “remarkably high” patient tolerability (70%) with 64 US-guided procedures, including 52 in clinical practice and 12 for research purposes. No major adverse events occurred, and biopsy usefulness was high, with 37% having a direct diagnostic impact and with 100% and 95% positive- and negative-predictive values for infection. Further, synovial tissues were retrieved in 88% of biopsies and a median of 75% of samples were gradable (Arthritis Care Res. 2019 Aug 17. doi: 10.1002/acr.24050).
A 2018 study of 524 synovial biopsies, including 402 performed using US-guided needle biopsy, performed at five centers across Europe similarly demonstrated safety and patient tolerability (RMD Open. 2018;4[2]:e000799. doi: 10.1136/mdopen-2018-000799).
Building on the work in Europe, investigators at Northwestern launched the REASON study, assembling a consortium of academic rheumatology groups across the United States, training participants in minimally invasive US-guided joint biopsy techniques, and collecting and analyzing synovial tissue samples submitted by the participating centers.
Laura B. Hughes, MD, a professor at the University of Alabama at Birmingham and an investigator in both the REASON study and AMP, said in an interview that her experience with patients is similar.
“It has been very, very well tolerated,” she said of the biopsy procedure used in the course of the studies – and that’s despite the time and commitment required, she added, explaining that 12 samples, each requiring a separate injection, are obtained over a 30- to 45-minute visit.
“We’ve had no problems, no complications,” she said, also noting the importance of careful patient selection.
Patients are altruistic; they want to be a part of moving things forward and helping other patients, and they have been more than willing to participate, both she and Dr. Perlman noted.
In fact, the REASON study investigators reported that performance of STB by rheumatologists in the United States is feasible and generates high-quality samples.
Further, the transcriptional profiles of isolated RA synovial macrophages identified from samples submitted by Dr. Hughes and others in the network characterized subpopulations of patients and identified six novel transcriptional modules associated with disease activity and therapy, underscoring the potential for precision medicine in RA.
“We posit that transcriptional signatures in macrophages ... will predict responsiveness to specific nonbiologic and/or biologic therapies,” they wrote, adding that future studies will “entail collection of synovial biopsy specimens from a larger cohort longitudinally, prior to, and following therapy.”
The ongoing National Institutes of Health–funded AMP Network research is also using synovial biopsies, but more for identification of molecular pathways with a focus on potential drug development.
A 2019 report from the AMP investigators described their integrated use of single-cell transcriptomics and mass cytometry to reveal cell states expanded in RA synovia and the mapping of inflammatory mediators to their source cell populations, which may be key mediators of RA pathogenesis.
“We observed upregulation of chemokines (CXCL8, CXCL9, and CXCL13), cytokines (IFNG and IL15), and surface receptors (PDGFRB and SMAMF7) in distinct immune and stromal cell populations, suggesting potential novel targets,” they wrote (Nat Immunol. 2019 Jul;20[7]:928-42).
Next steps
These reports, along with the thousands of papers published over the past few decades describing phenotypic and functional abnormalities in synovial tissue obtained from RA patients undergoing joint replacement surgery or, more recently, via STB early in the course of disease, have provided a wealth of information, Helen Michelle McGettrick, MD, noted in an editorial addressing the potential of STB analysis for “unlocking the hidden secrets to personalized medicine.”
The question, however, is whether they have moved the field closer to “translating this discovery science into new biomarkers or drugs to improve diagnosis or prognosis,” she wrote (Arthritis Res Ther. 2019;21[90]. doi: 10.1186/s13075-019-1871-5).
“Three sides of our square are in place: clinical expertise, technology, and patient willingness,” she said, arguing that the fourth side is “standardization in the handling, evaluation, and interpretation of STB.”
In fact, her editorial focused on a joint consensus of the European League Against Rheumatism Synovitis Study Group and the OMERACT Synovial Tissue Biopsy Group (Arthritis Res Ther. 2018;20[265]. doi: 10.1186/s13075-018-1762-1).
The groups, based on member survey responses, proposed a “consensual set of analysis items” to be used for synovial biopsies in clinical practice and translational research, including matters such as biopsy sampling, histologic criteria, and biopsy interpretation. Their work, according to Dr. McGettrick and the authors themselves, marked a step forward, but provided only a foundation for a standardization framework.

Low-dose methotrexate trial pins down adverse event rates
A new study has found an elevated risk of some adverse events in patients treated with low-dose methotrexate, compared with patients treated with placebo.
“The data presented here provide an important source of new evidence to improve the monitoring guidelines and safe prescribing of LD-MTX [low-dose methotrexate],” wrote Daniel H. Solomon, MD, of Brigham and Women’s Hospital and Harvard Medical School in Boston, and coauthors. The study was published in Annals of Internal Medicine.
To determine the rates of adverse events (AEs) among LD-MTX users, along with assessing the risks of certain predefined AEs, the researchers enrolled 6,158 patients in the Cardiovascular Inflammation Reduction Trial (CIRT) and randomized 4,786 of those patients to two groups: those receiving LD-MTX (n = 2,391) and those receiving placebo (n = 2,395). The median dose was 15 mg per week, and median follow-up was 23 months. All participants in CIRT had a history of cardiovascular disease, along with diabetes or metabolic syndrome. Just over 81% of the participants were male, and nearly 85% were white. Their median age was nearly 66 years.
Of the participants in the LD-MTX group, 2,156 (90.2%) had an AE and 2,080 (87.0%) had an AE of interest, which included infectious, hematologic, pulmonary, hepatic, cancerous, and gastrointestinal AEs. Of the participants in the placebo group, 2,076 (86.7%) had an AE and 1,951 (81.5%) had an AE of interest. As such, the relative rate of an AE of interest was 17% higher in the LD-MTX group (hazard ratio, 1.17; 95% confidence interval, 1.10-1.25).
In regard to specific types of AEs, the rates of gastrointestinal (HR, 1.23; 95% CI, 1.03-1.47), pulmonary (HR, 1.42; 95% CI, 1.14-1.77), infectious (HR, 1.15; 95% CI, 1.01-1.30) and hematologic (HR, 1.22; 95% CI, 1.11-1.34) were higher for participants in the LD-MTX group. Five cases of cirrhosis were found in the LD-MTX group, compared with none in the placebo group; none of the patients with cirrhosis had severe liver test abnormalities before their diagnosis. While the risk of cancer overall was not elevated in the LD-MTX group, 53 participants in that group developed skin cancer, compared with 26 in the placebo group (HR, 2.04; 95% CI, 1.28-3.26). Renal AEs were among the few that decreased in LD-MTX users (HR, 0.85; 95% CI, 0.78-0.93).
“Methotrexate has become the standard of care for RA patients,” Dr. Solomon said in an interview, “and because it worked so well, we accepted it without large placebo-controlled trials and without a precise understanding of the risk factors for AEs. Until this study, our evidence basis for the side-effect profile was relatively weak.
“We had a limited data set but decades of experience,” he added. “Now we have better evidence, for example, that methotrexate is associated with elevations in liver function tests. We even found five cases of cirrhosis. And the people who developed cirrhosis didn’t have severe test abnormalities; just minor ones over many months. So now we have a better understanding of the potential impact of minor, yet chronic abnormalities.”
Dr. Solomon and coauthors acknowledged their study’s limitations, including CIRT not including patients with systemic rheumatic disease and the possibility that participants did not report AEs that occurred in between routine study visits. In addition, although the median follow-up of nearly 2 years was longer than in other LD-MTX trials, they noted that “it may still be too short to observe some AEs that require long-term exposure.”
Dr. Solomon and colleagues should be commended for undertaking a long-awaited randomized, placebo-controlled trial that adds much-needed insight into how and when to monitor patients being treated with MTX, Vivian P. Bykerk, MD, of the Hospital for Special Surgery and Weill Cornell Medical College in New York, wrote in an editorial (Ann Intern Med. 2020 Feb 17. doi: 10.7326/M20-0435).
Dr. Bykerk noted that although the results may not be applicable to patients with RA and other inflammatory arthritides who are treated with MTX – RA patients in particular are younger, more often female, have lower rates of diabetes, and usually receive higher doses than those used in CIRT — the risk estimates from the CIRT study are “largely congruent with those expected in MTX-treated patients with rheumatic diseases.”
Regardless, she emphasized that this is a step in a much-needed direction, reminding physicians that “MTX use has inherent risks” and that its AEs, although infrequent, are clinically serious.
The National Institutes of Health funded the study. Various authors reported receiving grants from the National Heart, Lung, and Blood Institute, along with grants, research support, and personal fees from numerous pharmaceutical companies before and during the study. Dr. Bykerk reported receiving personal fees, grants, and nonfinancial support from pharmaceutical companies, foundations, and the NIH.

Some relevant financial conflicts go undisclosed in ACR guidelines
Over one-third of undisclosed industry payments made to physician-authors of American College of Rheumatology clinical practice guidelines were relevant to guideline recommendations, according to a recent review in Arthritis & Rheumatology.
Since 2014, 56 of 89 total physician-authors across five ACR clinical practice guidelines have been paid a total of $9,728,751 from industry sources. Nineteen of 89 authors received $1,961,362 in industry payments that were directly relevant to a guideline’s recommendations, and $699,561 of these payments (35.7%) were undisclosed, according to Cole Wayant, of the Oklahoma State University Center for Health Sciences, Tulsa, and colleagues.
The ACR’s Policy and Procedure Manual for Clinical Practice Guidelines, last updated in January 2015, allows up to 49% of authors in a clinical practice guideline to have financial conflicts of interest, including intellectual conflicts of interest, and requires them to report those relationships. When the ACR creates a call for letters of interest for a guideline, it includes a list of companies and organizations that could be affected by the guideline topic. To be considered conflict free, an author must not have ties to these companies and organizations for 1 year before the deadline on the letter of interest and 1 year after a guideline is published. This policy extends to members of an ACR guideline development group, literature review team, and voting panel. Under these guidelines, an author who has any relationship with a company is considered conflicted, which counts toward this total.
Mr. Wayant and colleagues performed a cross-sectional study of five ACR guidelines published since August 2014 on axial spondyloarthritis (27 authors), glucocorticoid-induced osteoporosis (21 authors), RA (26 authors), perioperative management of antirheumatic medication (31 authors), and polymyalgia rheumatica (46 authors). Using the Open Payments Database, the researchers searched for any general (speaking fees, consulting fees, education, honoraria, travel, food, or beverage payments) research, associated research, and ownership (stocks or dividends) relationships reported by guideline authors in the 12 months before a guideline was published. The guidelines on axial spondyloarthritis, glucocorticoid-induced osteoporosis, and RA contained specific recommendations for classes of medications or branded drugs, and conflicts from authors in those guidelines were assessed to determine relevancy of those payments.
Of the 56 physician-authors who received at least one payment (62.9%), the median payment was $522. However, 51 authors reported receiving more than $1,000, 42 authors reported more than $10,000, 20 authors reported more than $100,000, and 2 authors reported more than $1 million. Overall, 14 of 56 authors (25.0%) reported having no financial conflicts of interest, but did in fact receive some payment, and $4,189,090 of the $9,728,751 (43.1%) was not reported. The researchers said that the 19 authors with directly relevant payments were members of the voting panel (11 authors), literature review team (6 authors), and core leadership team (3 authors).
Physician-authors of clinical practice guidelines receiving payments from industry is not an issue specific to rheumatology. In an interview, Mr. Wayant said that authors of clinical guidelines across many different medical specialties often work closely with industry and hold “numerous conflicts of interest.”
“If professional societies are meant to be the public face of specialty providers, one would expect the guideline authors to resemble all society members,” Mr. Wayant said. “However, we routinely find that authors of professional society guidelines have large financial conflicts of interest that exceed the national average, indicating that the views and opinions of guideline authors may not reflect the opinion of most providers.”
These financial relationships between industry and physician authors have been shown to affect research results. A Cochrane Review published in 2017 evaluating industry sponsorship and research outcomes found that studies sponsored by industry were more likely to have favorable efficacy results and conclusions, compared with studies not sponsored by industry sources (Cochrane Database Syst Rev. 2017 Feb 16;2:MR000033). As medical societies continue to become more involved with clinical practice guidelines, recommendations from physician-authors with financial ties to industry can present a conflict of interest. Recommendations in clinical practice guidelines often affect reimbursement of a drug from insurance, and an author can vote for a drug recommendation in a guideline that may not match patient values and preferences, noted Mr. Wayant.
“These authors are fundamentally different from the average rheumatologist that stays up to date with the medical literature, in terms of financial ties to industry,” he said. “Removing the influence of for-profit companies from guideline development cannot harm the rigor of the guideline recommendations, since many medical professionals without conflicts are experts in evidence-based medicine and study appraisal.”
Being financially linked to industry does not automatically make one the most qualified candidate for deciding which therapies are best for patients, Mr. Wayant explained, and guidelines should reflect the values of patients and the medical profession, rather than industry.
“Given the importance of guidelines, [we] encourage the ACR and all professional societies to do everything possible to be above reproach and seek out authors who do not have financial conflicts to write the guidelines,” he said.
The authors reported having no funding source for the study. One author reported serving on an advisory board for Janssen involving infliximab and golimumab, for Sanofi Genzyme involving sarilumab, and receiving payment for a survey from Comsort. The other authors reported having no conflicts of interest.

Tramadol use for noncancer pain linked with increased hip fracture risk
The risk of hip fracture was higher among patients treated with tramadol for chronic noncancer pain than among those treated with other commonly used NSAIDs in a large population-based cohort in the United Kingdom.
The incidence of hip fracture over a 12-month period among 293,912 propensity score-matched tramadol and codeine recipients in The Health Improvement Network (THIN) database during 2000-2017 was 3.7 vs. 2.9 per 1,000 person-years, respectively (hazard ratio for hip fracture, 1.28), Jie Wei, PhD, of Xiangya Hospital, Central South University, Changsha, China, and colleagues reported in the Journal of Bone and Mineral Research.
Hip fracture incidence per 1,000 person-years was also higher in propensity score–matched cohorts of patients receiving tramadol vs. naproxen (2.9 vs. 1.7; HR, 1.69), ibuprofen (3.4 vs. 2.0; HR, 1.65), celecoxib (3.4 vs. 1.8; HR, 1.85), or etoricoxib (2.9 vs. 1.5; HR, 1.96), the investigators found.
Tramadol is considered a weak opioid and is commonly used for the treatment of pain based on a lower perceived risk of serious cardiovascular and gastrointestinal effects versus NSAIDs, and of addiction and respiratory depression versus traditional opioids, they explained. Several professional organizations also have “strongly or conditionally recommended tramadol” as a first- or second-line treatment for conditions such as osteoarthritis, fibromyalgia, and chronic low back pain.
The potential mechanisms for the association between tramadol and hip fracture require further study, but “[c]onsidering the significant impact of hip fracture on morbidity, mortality, and health care costs, our results point to the need to consider tramadol’s associated risk of fracture in clinical practice and treatment guidelines,” they concluded.
This study was supported by the National Institutes of Health, the National Natural Science Foundation of China, and the Postdoctoral Science Foundation of Central South University. The authors reported having no conflicts of interest.

Fast-track surgery for hip fracture does not reduce mortality
An accelerated path to surgery after hip fracture did not improve mortality or major complications, according to a new international randomized trial. However, a fast track to surgery hastened mobilization, weight-bearing, and hospital discharge, and reduced the risk of urinary tract infection and delirium.
The HIP ATTACK (Hip Fracture Accelerated Surgical Treatment and Care Track) study enrolled 2,970 patients (median age, 79 years; 69% women) during March 2014-May 2019. The study excluded patients younger than 45 years, as well as those who were on nonreversible anticoagulation and who had high-energy or more complex hip fractures. In all, 1,487 patients were randomly assigned to the accelerated-surgery group, which received early medical evaluation with a goal of heading to surgery within 6 hours of a hip fracture diagnosis. The goal was achieved, with patients in the intervention arm receiving care at a median 6 hours after diagnosis. Patients in the 69 participating hospitals in 17 countries who were assigned to standard of care received surgery at a median 24 hours after diagnosis (P less than .001).
“Observational data, clinical experience, and biological rationale suggest that the longer a patient is immobile and lying in a bed, the higher the risk of poor outcomes,” wrote principal investigators Philip J. Devereaux, MD, PhD, and Mohit Bhandari, MD, PhD, of McMaster University, Hamilton, Ont., and their colleagues on the HIP ATTACK writing committee.
The study was the first large, randomized trial that directly compared accelerated surgery with standard of care, noted the authors. Previous observational studies had shown worse outcomes for those usual-care patients who waited longer for surgery.
In HIP ATTACK, there was no difference in the primary outcome measures of 90-day mortality and major complications for patients receiving surgery within 6 hours after hip fracture diagnosis, compared with those who received surgery within 24 hours. The coprimary outcome measures included serious complications, such as MI, stroke, venous thromboembolism, sepsis, pneumonia, and life-threatening or major bleeding.
In practice, the researchers found that patients in the accelerated-surgery group received medical clearance in a median time of 2 hours after a diagnosis of hip fracture, whereas the standard of care group was cleared in 4 hours.
At 90 days, 9% of patients in the accelerated-surgery group and 10% of those in the usual-care group had died, a nonsignificant difference between the two groups. In both groups, 22% of patients experienced a major complication. A post hoc analysis that looked for any site-clustering effects did not detect different outcomes, the investigators wrote.
Delirium occurred in 132 patients (9%) of the accelerated-surgery group and in 175 patients (12%) in the usual-care group (odds ratio, 0.72; 95% confidence interval, 0.58-0.92). Infection without sepsis and urinary tract infection were both less common in the accelerated-surgery group (hazard ratio, 0.80 and 0.78, respectively).
The authors noted that the potential benefits of a speedy course to surgery, including reduced immobility and less pain, could be negated if physicians had less time to optimize medical care for older patients with multiple comorbidities and who make up a significant proportion of those who sustain low-energy hip fractures. However, medical complications, such as MI and new-onset atrial fibrillation, were not seen more frequently in the accelerated-surgery group.
In an editorial accompanying the study, Alejandro Lizaur-Utrilla, MD, and Fernando Lopez-Prats, MD, of the Universidad Miguel Hernández, Alicante, Spain, observed that the 6-hour window for hip fracture surgery may be difficult to achieve given clinical practicalities and that, in some cases, the 6-hour window might be unavoidable if severe comorbidities and overall poor health make early surgery inadvisable.
They also expressed concern that, despite the lack of harm shown in the patients who underwent accelerated surgery, the surgery “might negatively affect patients’ outcomes by preventing or limiting the opportunity for optimization of patients’ medical conditions before surgery.” They called for further study to delineate how fitness for surgery affects outcomes in accelerated surgery and to further examine whether the better outcomes are associated with improved cost-effectiveness.
Multiple HIP ATTACK coinvestigators reported relationships with pharmaceutical and medical device companies, including companies that manufacture hip prosthesis and orthopedic surgical devices and implants. The study was sponsored by the Canadian Population Health Research Institute, the Ontario Strategy for Patient Oriented Research Support Unit, the Ontario Ministry of Health and Long-Term Care, the Hamilton Health Sciences Foundation, Physicians’ Services Incorporated Foundation, Michael G. DeGroote Institute for Pain Research and Care, Smith & Nephew (to recruit patients in Spain), and Indiegogo Crowdfunding.

In practice, the researchers found that patients in the accelerated-surgery group received medical clearance in a median time of 2 hours after a diagnosis of hip fracture, whereas the standard of care group was cleared in 4 hours.
At 90 days, 9% of patients in the accelerated-surgery group and 10% of those in the usual-care group had died, a nonsignificant difference between the two groups. In both groups, 22% of patients experienced a major complication. A post hoc analysis that looked for any site-clustering effects did not detect different outcomes, the investigators wrote.
Delirium occurred in 132 patients (9%) of the accelerated-surgery group and in 175 patients (12%) in the usual-care group (odds ratio, 0.72; 95% confidence interval, 0.58-0.92). Infection without sepsis and urinary tract infection were both less common in the accelerated-surgery group (hazard ratio, 0.80 and 0.78, respectively).
The authors noted that the potential benefits of a speedy course to surgery, including reduced immobility and less pain, could be negated if physicians had less time to optimize medical care for older patients with multiple comorbidities and who make up a significant proportion of those who sustain low-energy hip fractures. However, medical complications, such as MI and new-onset atrial fibrillation, were not seen more frequently in the accelerated-surgery group.
In an editorial accompanying the study, Alejandro Lizaur-Utrilla, MD, and Fernando Lopez-Prats, MD, of the Universidad Miguel Hernández, Alicante, Spain, observed that the 6-hour window for hip fracture surgery may be difficult to achieve given clinical practicalities and that, in some cases, the 6-hour window might be unavoidable if severe comorbidities and overall poor health make early surgery inadvisable.
They also expressed concern that, despite the lack of harm shown in the patients who underwent accelerated surgery, the surgery “might negatively affect patients’ outcomes by preventing or limiting the opportunity for optimization of patients’ medical conditions before surgery.” They called for further study to delineate how fitness for surgery affects outcomes in accelerated surgery and to further examine whether the better outcomes are associated with improved cost-effectiveness.
Multiple HIP ATTACK coinvestigators reported relationships with pharmaceutical and medical device companies, including companies that manufacture hip prosthesis and orthopedic surgical devices and implants. The study was sponsored by the Canadian Population Health Research Institute, the Ontario Strategy for Patient Oriented Research Support Unit, the Ontario Ministry of Health and Long-Term Care, the Hamilton Health Sciences Foundation, Physicians’ Services Incorporated Foundation, Michael G. DeGroote Institute for Pain Research and Care, Smith & Nephew (to recruit patients in Spain), and Indiegogo Crowdfunding.
