Comparing methotrexate monotherapy with methotrexate plus leflunomide combination therapy in psoriatic arthritis (COMPLETE-PsA): a double-blind, placebo-controlled, randomised, trial

Background Conventional synthetic disease-modifying anti-rheumatic drugs (DMARDs) are the preferred first-line treatment in patients with psoriatic arthritis, although there is a paucity of evidence for the efficacy of conventional synthetic DMARDs and especially their combination. We aimed to investigate whether a combination of methotrexate plus leflunomide is superior to methotrexate monotherapy at improving disease activity in patients with psoriatic arthritis. Methods This single centre, investigator-initiated, double-blind, randomised, placebo-controlled trial was conducted at Sint Maartenskliniek in the Netherlands (locations included Boxmeer, Geldrop, Woerden, and Nijmegen). Patients aged 16 years or older with a clinical diagnosis of psoriatic arthritis and active disease (defined as two or more swollen joints; dactylitis counting as one swollen joint) were included. Patients were randomly allocated (1:1) and stratified by high disease activity (psoriatic arthritis disease activity score [PASDAS] ≥5·4) to either methotrexate plus leflunomide (combination therapy) or methotrexate plus placebo (monotherapy), using computer-generated stratified variable block randomisation. In both groups, patients received oral methotrexate 15 mg per week for the first 4 weeks and 25 mg per week thereafter combined with two leflunomide 10 mg tablets once per day or two placebo tablets. During the study period, the patients, nurses, researchers, and treating physicians were all masked to treatment allocation. The primary outcome was the difference in mean PASDAS at week 16, adjusted for baseline PASDAS, between the combination and monotherapy groups, assessed in the intention-to-treat population. This trial was registered with the Netherlands Trial Register (NL7404) on Dec 3, 2018. Findings Between Feb 19, 2019, and March 11, 2021, 82 patients were screened for eligibility. Four patients were ineligible and 78 were enrolled and randomly assigned to either methotrexate plus leflunomide (n=39) or methotrexate plus placebo (n=39). 50 (64%) of 78 patients were male, 28 (36%) were female, and the median age of patients was 55·0 years (IQR 42·0–64·0). Methotrexate plus leflunomide combination therapy was superior to methotrexate monotherapy at week 16 (PASDAS 3·1 [SD 1·4] vs 3·7 [SD 1·3]; treatment difference –0·6, 90% CI –1·0 to –0·1; p=0·025). There were no study deaths. The most frequently occurring adverse events were nausea or vomiting (17 [44%] of 39 patients in the methotrexate plus leflunomide group vs 11 [28%] of 39 in the methotrexate plus placebo group), tiredness (9 [23%] vs 13 [33%]) and elevated alanine aminotransferase (12 [31%] vs 7 [18%]. Generally, the incidence of mostly mild adverse events was higher in the methotrexate plus leflunomide group than in the methotrexate plus placebo group. Interpretation Methotrexate plus leflunomide combination therapy results in greater improvement in disease activity according to PASDAS in patients with psoriatic arthritis. However, methotrexate plus leflunomide combination therapy is less well tolerated than methotrexate monotherapy. Funding Regional Junior Researcher Grant from the Sint Maartenskliniek

Prevalence and predictors of health care use in patients with early hip or knee osteoarthritis: two-year follow-up data from the CHECK cohort

Objective: To describe health care utilization (HCU) and predict analgesic use and health professional (HP) contact at baseline and 2 years in individuals with early symptomatic hip and/or knee osteoarthritis (OA). Design: Baseline and two-year data on HCU of the 1002 participants from the multi-centre Cohort Hip & Cohort Knee study were used. Six forms of health care services were described: analgesic use, supplement use, contact with a General Practitioner (GP), contact with a HP, contact in secondary care, and alternative medicine use. Multivariable logistic regression was performed in order to identify predisposing, enabling and disease-related variables that predict analgesic use and HP contact at 2 y Results: For the hip (n = 170), the knee (n = 414) and the hip and knee (n = 418) group analgesic use (38%, 29% and 47%, respectively), contact with a GP (32%, 38% and 36%, respectively) and contact with a HP (26%, 18% and 20%, respectively), were reported most often at baseline. Contact with a GP significantly decreased, supplement use increased (to about one third), and other treatment modalities remained stable at 2 years. In all three groups, analgesic use at baseline was the strongest predi Conclusions: In early OA, familiarity with HCU and other predisposing factors are, apart from disease-related factors strongly associated with HCU at 2 years. Further research is necessary to examine whether our findings reflect sub-optimal management of early OA in terms of efficacy and equity. (C) 2012 Osteoarthritis Research Society International.

Implementation of protocolized tight control and biological dose optimization in daily clinical practice: results of a pilot study

Objectives: To assess the effects of education, guideline development, and individualized treatment advice on rheumatologist adherence to tight control-based treatment and biological dose optimization in rheumatoid arthritis (RA), psoriatic arthritis (PsA), and spondyloarthropathy (SpA) patients. Method: This pilot study, among two rheumatologists and two specialized nurses in a general hospital, combined education, feedback, local guideline development, and individualized treatment advice. Outcomes (baseline and 1year post-intervention) were the percentage of patients with a Disease Activity Score in 28 joints (DAS28) or Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) measured during the visit, mean DAS28/BASDAI, and the percentage of patients using a reduced biological dose. DAS28 outcomes only applied to RA and PsA patients, BASDAI outcomes only applied to SpA patients whereas outcomes on biological dose applied to all patients. Results: A total of 232 patients (67% RA, 15% PsA, 18% SpA; 58% female, mean age 5615years) were included in the study. The percentage of DAS28 and BASDAI measurements performed increased after the intervention [DAS28 15-51%, odds ratio (OR) 3.3, 95% confidence interval (CI) 2.1-5.5; BASDAI 23-50%, OR 2.2, 95% CI 1.0-5.5], with mean DAS28 and BASDAI scores remaining similar (DAS28: mean difference 0.1, 95% CI -0.3 to 0.5; BASDAI: mean difference 0.03, 95% CI -1.8 to 1.9). Use of a reduced biological dose increased from 10% to 61% (OR 3.9, 95% CI 2.4-6.5). Conclusions: A multicomponent intervention strategy aimed at rheumatologists can lead to improved adherence to tight control-based treatment and a reduction in the use of biologicals in RA, SpA, and PsA patient
