Obesity and Rheumatoid Arthritis. A bad association

Estándar

– A new study offers a double message about the potential impact of obesity on systemic lupus erythematosus (SLE) in women: Excess pounds are linked to a higher risk of patient-reported outcomes such as pain and fatigue, and body mass index may be an appropriate tool to study weight issues in this population.

 

For the new study, Dr. Patterson and her colleagues analyzed findings from surveys of 148 participants in the Arthritis Body Composition and Disability study. All participants were women with a verified SLE diagnosis.

About two-thirds of the sample were white, 14% were Asian, and 13% were African American. The average age was 48 years, the average disease duration was 16 years, and 45% took glucocorticoids.

Researchers used two measurements of obesity: BMI of 30 kg/m2 or greater and fat mass index (FMI) of 13 kg/m2 or greater.

They calculated FMI with data collected via whole dual x-ray absorptiometry. Of the participants, 32% and 30% met criteria for obesity under FMI and BMI definitions, respectively.

Researchers also collected survey data regarding measurements of disease activity, depressive symptoms, pain and fatigue.

The study authors controlled their results to account for factors such as age, race, and prednisone use. They found that those defined as obese via FMI had more disease activity and depression than did nonobese women: 14.8 versus 11.5, P = .010, on the Systemic Lupus Activity Questionnaire scale, and 19.8 versus 13.1, P = .004, on the Center for Epidemiologic Studies Depression scale.

On two other scales of pain and fatigue, obese patients scored lower – a sign of worse status – compared with nonobese women: 38.7 versus 44.2, P = .004, on the Short Form 36 (SF-36) Health Survey pain subscale and 39.6 versus 45.2, P= .010, on the SF-36 vitality subscale. The researchers reported similar findings when using BMI to assess obesity.

It’s not clear why obesity and lupus may be linked, Dr. Patterson said, though she noted that inflammation is a shared factor. “People with lupus have arthritis and chronic pain, so there may be this vicious feedback cycle with hindrances to be able to live healthy lifestyles,” she added.

The study has limitations, including that the sample is largely white, while lupus is more common among minority women. In addition, the study does not include underweight patients or track patients over time. “It will be important to look at obesity and patient-reported outcomes to determine whether weight loss results in better outcomes,” Dr. Patterson said.

The study does provide an extra benefit by suggesting that BMI is not an inferior tool to measure the effects of obesity in the SLE population, Dr. Patterson said. BMI has been criticized as a misleading measurement of obesity. But the BMI and FMI measures produced similar results in this study. “That’s really good news in a way for the practicalities of using this information,” she said.

But FMI may still be a better measurement of obesity in the general population, where BMI may be more likely to be thrown off by high muscle mass.

It may seem obvious that obesity is linked to worse lupus outcomes, but rheumatologist Bryant England, MD, of the University of Nebraska, Omaha, said that this research is noteworthy because it highlights the importance of focusing on obesity in the clinic.

Rheumatologists shouldn’t leave obesity to primary care physicians but instead confront it themselves, said Dr. England, who moderated a discussion of new research at an ACR annual meeting press conference. But he cautioned that prudence is especially important when talking about obesity with lupus patients because they may be sensitive about medication-related weight gain.

Dr. Patterson and the other study authors reported having no relevant disclosures. Dr. England also reported no relevant disclosures. The study was funded by the National Institute of Arthritis and Musculoskeletal and Skin Diseases.

Tapering/Discontinuing Biologics

Estándar

Hi friends, on these days I’m in Brazil visiting my colleagues of this beautiful country. One of the principal purposes of this trip is to discuss with them the important issue of tapering (or discontinuing) biologics in rheumatic conditions, once the patient has achieved a good clinical status (remission or low disease activity). There is a lot of evidence, but unfortunately, many studies have been conducted in patients (that in our clinical setting) they shouldn’t be candidates to receive biologics. Nonetheless, after an extensive review, I could achieve some conclusions that I intend to share with you once my visit has ended. Then, it will be great getting your feedback. Now as a starter, I attach the outline of my presentation. Cheers…

Adalimumab plus Methotrexate for Uveitis in Juvenile Idiopathic Arthritis

Estándar

Athimalaipet V. Ramanan, F.R.C.P.C.H.,

BACKGROUND

Adalimumab, a fully human anti–tumor necrosis factor α monoclonal antibody, is effective in the treatment of juvenile idiopathic arthritis (JIA). We tested the efficacy of adalimumab in the treatment of JIA-associated uveitis.

METHODS

In this multicenter, double-blind, randomized, placebo-controlled trial, we assessed the efficacy and safety of adalimumab in children and adolescents 2 years of age or older who had active JIA-associated uveitis. Patients who were taking a stable dose of methotrexate were randomly assigned in a 2:1 ratio to receive either adalimumab (at a dose of 20 mg or 40 mg, according to body weight) or placebo, administered subcutaneously every 2 weeks. Patients continued the trial regimen until treatment failure or until 18 months had elapsed. They were followed for up to 2 years after randomization. The primary end point was the time to treatment failure, defined according to a multicomponent intraocular inflammation score that was based on the Standardization of Uveitis Nomenclature criteria.

RESULTS

The prespecified stopping criteria were met after the enrollment of 90 of 114 patients. We observed 16 treatment failures in 60 patients (27%) in the adalimumab group versus 18 treatment failures in 30 patients (60%) in the placebo group (hazard ratio, 0.25; 95% confidence interval [CI], 0.12 to 0.49; P<0.0001 [the prespecified stopping boundary]). Adverse events were reported more frequently in patients receiving adalimumab than in those receiving placebo (10.07 events per patient-year [95% CI, 9.26 to 10.89] vs. 6.51 events per patient-year [95% CI, 5.26 to 7.77]), as were serious adverse events (0.29 events per patient-year [95% CI, 0.15 to 0.43] vs. 0.19 events per patient-year [95% CI, 0.00 to 0.40]).

CONCLUSIONS

Adalimumab therapy controlled inflammation and was associated with a lower rate of treatment failure than placebo among children and adolescents with active JIA-associated uveitis who were taking a stable dose of methotrexate. Patients who received adalimumab had a much higher incidence of adverse events and serious adverse events than those who received placebo.

2016 updated EULAR evidence-based recommendations for the management of gout

Estándar

P. Richette

Abstract

Background New drugs and new evidence concerning the use of established treatments have become available since the publication of the first European League Against Rheumatism (EULAR) recommendations for the management of gout, in 2006. This situation has prompted a systematic review and update of the 2006 recommendations.

Methods The EULAR task force consisted of 15 rheumatologists, 1 radiologist, 2 general practitioners, 1 research fellow, 2 patients and 3 experts in epidemiology/methodology from 12 European countries. A systematic review of the literature concerning all aspects of gout treatments was performed. Subsequently, recommendations were formulated by use of a Delphi consensus approach.

Results Three overarching principles and 11 key recommendations were generated. For the treatment of flare, colchicine, non-steroidal anti-inflammatory drugs (NSAIDs), oral or intra-articular steroids or a combination are recommended. In patients with frequent flare and contraindications to colchicine, NSAIDs and corticosteroids, an interleukin-1 blocker should be considered. In addition to education and a non-pharmacological management approach, urate-lowering therapy (ULT) should be considered from the first presentation of the disease, and serum uric acid (SUA) levels should be maintained at<6 mg/dL (360 µmol/L) and <5 mg/dL (300 µmol/L) in those with severe gout. Allopurinol is recommended as first-line ULT and its dosage should be adjusted according to renal function. If the SUA target cannot be achieved with allopurinol, then febuxostat, a uricosuric or combining a xanthine oxidase inhibitor with a uricosuric should be considered. For patients with refractory gout, pegloticase is recommended.

Conclusions These recommendations aim to inform physicians and patients about the non-pharmacological and pharmacological treatments for gout and to provide the best strategies to achieve the predefined urate target to cure the disease.

EULAR recommendations for the management of rheumatoid arthritis with synthetic and biological disease-modifying antirheumatic drugs: 2016 update

Estándar

J. Smolen et al.

Abstract

Recent insights in rheumatoid arthritis (RA) necessitated updating the European League Against Rheumatism (EULAR) RA management recommendations. A large international Task Force based decisions on evidence from 3 systematic literature reviews, developing 4 overarching principles and 12 recommendations (vs 3 and 14, respectively, in 2013). The recommendations address conventional synthetic (cs) disease-modifying antirheumatic drugs (DMARDs) (methotrexate (MTX), leflunomide, sulfasalazine); glucocorticoids (GC); biological (b) DMARDs (tumour necrosis factor (TNF)-inhibitors (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab), abatacept, rituximab, tocilizumab, clazakizumab, sarilumab and sirukumab and biosimilar (bs) DMARDs) and targeted synthetic (ts) DMARDs (Janus kinase (Jak) inhibitors tofacitinib, baricitinib). Monotherapy, combination therapy, treatment strategies (treat-to-target) and the targets of sustained clinical remission (as defined by the American College of Rheumatology-(ACR)-EULAR Boolean or index criteria) or low disease activity are discussed. Cost aspects were taken into consideration. As first strategy, the Task Force recommends MTX (rapid escalation to 25 mg/week) plus short-term GC, aiming at >50% improvement within 3 and target attainment within 6 months. If this fails stratification is recommended. Without unfavourable prognostic markers, switching to—or adding—another csDMARDs (plus short-term GC) is suggested. In the presence of unfavourable prognostic markers (autoantibodies, high disease activity, early erosions, failure of 2 csDMARDs), any bDMARD (current practice) or Jak-inhibitor should be added to the csDMARD. If this fails, any other bDMARD or tsDMARD is recommended. If a patient is in sustained remission, bDMARDs can be tapered. For each recommendation, levels of evidence and Task Force agreement are provided, both mostly very high. These recommendations intend informing rheumatologists, patients, national rheumatology societies, hospital officials, social security agencies and regulators about EULAR’s most recent consensus on the management of RA, aimed at attaining best outcomes with current therapies.

2016 update of the EULAR recommendations for the management of early arthritis

Estándar

B. Combe et al.

Abstract

Objectives Since the 2007 recommendations for the management of early arthritis have been presented, considerable research has been published in the field of early arthritis, mandating an update of the 2007 European League Against Rheumatism (EULAR) recommendations for management of early arthritis.

Methods In accordance with the 2014 EULAR Standardised Operating Procedures, the expert committee pursued an approach that was based on evidence in the literature and on expert opinion. The committee involved 20 rheumatologists, 2 patients and 1 healthcare professional representing 12 European countries. The group defined the focus of the expert committee and target population, formulated a definition of ‘management’ and selected the research questions. A systematic literature research (SLR) was performed by two fellows with the help of a skilled librarian. A set of draft recommendations was proposed on the basis of the research questions and the results of the SLR. For each recommendation, the categories of evidence were identified, the strength of recommendations was derived and the level of agreement was determined through a voting process.

Results The updated recommendations comprise 3 overarching principles and 12 recommendations for managing early arthritis. The selected statements involve the recognition of arthritis, referral, diagnosis, prognostication, treatment (information, education, pharmacological and non-pharmacological interventions), monitoring and strategy. Eighteen items were identified as relevant for future research.

Conclusions These recommendations provide rheumatologists, general practitioners, healthcare professionals, patients and other stakeholders with an updated EULAR consensus on the entire management of early arthritis.
