Introduction: Rheumatoid arthritis (RA) is one of the most common chronic inflammatory diseases. The goal of this study was to analyze the risk of depression in patients diagnosed with RA and treated by general practitioners in the UK.
Methods: The present study included patients first diagnosed with RA between 2000 and 2014 (index date). Individuals were excluded if they had also been diagnosed with depression or if they had received therapy for depression at or prior to the index date. The primary outcome measure was the rate of patients with depression (ICD 10: F32, 33) within 5 years of the RA diagnosis. Demographic data included gender and age. Furthermore, a revised version of the Charlson comorbidity index was used as a generic marker of comorbidity.
Results: A total of 4187 patients were included in the study. After 5 years of follow-up, 23.7% of men and 36.5% of women had developed depression (log rank p value <0.001). Women were more likely to develop depression than men (HR 1.61, 95% CI 1.42-1.84). Age and Charlson comorbidity score had no significant impact on the risk of being diagnosed with this psychiatric disorder.
Conclusion: Around 30% of RA patients developed depression within 5 years of the RA diagnosis. The depression risk was higher in women than in men. The current findings also indicate that improved detection and treatment of patients with both RA and depression are important.

Disclosing the impact of metformin and methotrexate in adjuvant arthritis in female rats: molecular docking and biochemical insights on visfatin.

Rheumatoid arthritis (RA) is one of the most common systemic autoimmune inflammatory diseases, with a progressive etiology that results in serious complications and a higher chance of early death. Visfatin, an adipokine, is correlated with disease pathologic features and becomes a key biomarker and therapeutic target for RA. This study aimed to evaluate the anti-arthritic activity of metformin (an antidiabetic drug with anti-inflammatory activities) and methotrexate (the first choice for disease-modifying antirheumatic drugs in RA, with diverse adverse effects) in complete Freund's adjuvant (CFA)-induced arthritis in female rats.

Introduction: Our aim was to investigate the insufficiently understood differences in the immune system between anti-citrullinated peptide antibody (ACPA)-positive (ACPA) and ACPA-negative (ACPA) early rheumatoid arthritis (eRA) patients.
Methods: We performed multiple cytokine assays using sera from drug-naïve ACPA and ACPA eRA patients. Additionally, we conducted single-cell RNA sequencing of CD45 cells from peripheral blood samples to analyze and compare the distribution and functional characteristics of the cell subsets based on the ACPA status.

This pilot study investigates distinctive features within the nail-enthesis complex among Psoriatic arthritis (PsA), Psoriasis (PSO), Rheumatoid Arthrit is (RA), and Healthy Control (HC) groups, utilizing a combined approach of ultrasound (US) and nailfold videocapillaroscopy (NVC). Clinical assessments and comprehensive US and NVC evaluations of the nail-enthesis complex were conducted on 72 subjects (18 PsA, 16 PSO, 19 RA, 19 HC). Unsupervised clustering models and factor analysis were employed to identify patterns and interrelationships between US and NVC parameters.

Introduction: Periodontitis is associated with rheumatoid arthritis (RA). One hypothesis posits that this connection arises from the formation of autoantibodies against citrullinated proteins (ACPA) in inflamed gums, possibly triggered by . We previously demonstrated an increased antibody response to arginine gingipains (anti-Rgp IgG), not only in individuals with severe periodontitis compared to controls, but in RA versus controls, with an association to ACPA.

Autoimmune rheumatic diseases (ARDs) are a heterogeneous group of conditions characterized by excessive and misdirected immune responses against the body's own musculoskeletal tissues. Their exact aetiology remains unclear, with genetic, demographic, behavioural and environmental factors implicated in disease onset. One prominent hypothesis for the initial breach of immune tolerance (leading to autoimmunity) is molecular mimicry, which describes structural or sequence similarities between human and microbial proteins (mimotopes).
