Interobserver reliability of Masei index validation by a multicenter collaborative group of rheumatologists.

MASEI is the main validated ultrasound score for the evaluation of enthesis. The lack of studies facing the agreement to achieve for the interpretation of the MAdrid Sonographic Enthesis Index (MASEI) among researchers from different centers in multicenter studies is of concern. The aim of this multicenter was to evaluate the interobserver reliability of MASEI. An experienced ultrasonographer-rheumatologist performed ultrasound scans of the areas included in MASEI index in three patients with Ankylosing Spondylitis and Psoriatic Arthritis. Videos were captured. The videos were then evaluated by 24 rheumatologists of the ultrasound working group of the Catalan Society of Rheumatology (EcoCAT). A face-to-face training meeting was held. Ten days after the workshop, the study participants evaluated the videos. A reliability assessment was performed. The ICC for the MASEI scores after the workshop was of 0.97 (95% CI 89-99). Reliability did not vary statistically with examiner experience. Globally, no problems of reliability by structures were seen, and all the ICCs were above 0.90 and improved slightly after the educational program. However, the correlation observed between examiners at plantar aponeursis and triceps tendon was weak. The small variability observed in the results of the index validation in our study, suggests that the MASEI index is reproducible by different observers when those are well trained and show awesome results of the enthesis when examined by ultrasound.

Long-term survival of biological therapy in psoriatic arthritis: 18-year analysis of a cohort in a tertiary hospital.

To study retention of biologic disease-modifying anti-rheumatic drugs (bDMARDs) or apremilast and potential predictors of lack of response in patients with psoriatic arthritis (PsA). A single-center retrospective analysis of PsA patients who received ≥ 1 bDMARD or apremilast during 2000-2018. The main endpoint was lack of response (primary or secondary failure). Analyses included retention of DMARDs (Kaplan-Meier curves) and potential predictors of lack of response (bivariate and multivariate logistic regression models). A total of 159 patients with PsA received up to 8 DMARDs: etanercept (34%), adalimumab (30%), infliximab (9%), golimumab (9%), apremilast (7%), ustekinumab (5%), certolizumab (4%), and secukinumab (2%). Therapy was discontinued in 96 cases (60%), mainly owing to secondary failure (37%), followed by primary failure (25%) and adverse effects (24%). Retention was analyzed based on 313 units of analysis. Duration of follow-up was 846.1 treatment-years (maximum 14.8 years, median 2.75 years). A total of 172 DMARDs were discontinued. The probability of continuing the initial treatment was 37% at 5 years, 22% at 10 years, and 12% at 14 years. The longest medium retention time was observed for infliximab (6.2 years) and etanercept (4.5 years). Predictors of lack of response included male sex, number of swollen joints, and, especially, depression (OR = 35.2). The sensitivity and specificity of the model were 86.4% and 85.7%, respectively, with a coefficient of determination (R2) of 45.6 (ROC, 0.912). Rates of discontinuation due to primary and secondary failure are high in PsA. Retention is better for anti-TNF agents than for other agents.
