AI Article Synopsis

  • The study focuses on understanding why some early arthritis patients don’t stick to their medication (DMARDs) during the first three months of treatment.
  • Researchers analyzed responses from 301 participants about factors affecting adherence and found that while most patients started off well, adherence declined over time.
  • Key factors influencing adherence included active information-seeking behavior and having a positive outlook on their disease, while patients who felt passive or overwhelmed by pain were at a higher risk of not adhering to their treatment plan.

Article Abstract

Objectives: To induce disease remission, early arthritis patients should adhere to their disease-modifying antirheumatic drugs (DMARD) in the first months after diagnosis. It remains unknown why some patients are non-adherent. We aimed to identify patients at risk for non-adherence in the first 3 months of treatment.

Methods: Adult DMARD-naive early arthritis patients starting synthetic DMARDs filled out items on potential adherence predictors at baseline. Adherence was measured continuously. Non-adherence was defined as not opening the electronically monitored pill bottle when it should have been. Items were reduced and clustered using principal component analysis. The most discriminating items were identified with latent trait models. We used a multivariable logistic regression model to find non-adherence predictors.

Results: 301 patients agreed to participate. Adherence was high and declined over time. Principal component analysis led to 7 dimensions, while subsequent latent trait models analyses led to 15 dimensions. Two dimensions were associated with adherence, one dimension was associated with non-adherence.

Conclusions: Information seeking behavior and positive expectations about the course of the disease are associated with adherence. Patients who become passive because of pain are at risk for non-adherence.

Practice Implications: Rheumatologists have cues to identify non-adherence, and may intervene on non-adherence through implementing shared decision making techniques.

Sjögren disease (SjD) is a systemic autoimmune disorder affecting both children and adults, with a wide range of clinical phenotypes. It remains a challenging condition to recognise and diagnose early and manage effectively. The heterogeneous nature of the presentation, variable disease course and overlapping symptoms with other autoimmune conditions often result in delayed diagnosis.

Humans develop hyperuricemia via decreased urate elimination and excess urate production, consequently promoting monosodium urate crystal deposition and incident gout. Normally, approximately two thirds of urate elimination is renal. However, chronic kidney disease (CKD) and other causes of decreased renal urate elimination drive hyperuricemia in most with gout.

Autoimmune diseases are a heterogeneous group resulting from dysregulation or dysfunction of the immune system due to genetic predisposition and environmental triggers. It is common for these diseases to coexist. However, except for a single case secondary to varicella zoster virus infection, the association between juvenile idiopathic arthritis and acute cerebellitis has not been reported in the literature.

Aim: The continuous update of international guidelines and enhanced availability of biological disease-modifying antirheumatic drugs (bDMARDs) and targeted synthetic DMARDs (tsDMARDs) have made a significant impact on the diagnosis and treatment of early rheumatoid arthritis (ERA). This study aims to systematically evaluate the current treatment strategies and outcomes within a large-scale cohort of patients with ERA.

Methods: Data from the Chinese Registry of Rheumatoid Arthritis (CREDIT), a large multicenter Chinese registry of RA, were collected to analyze temporal trends in clinical profiles, therapeutic strategies, and treatment outcomes among patients with ERA.
