Objective: To construct a predictive model for Psoriatic Arthritis (PsA) based on clinical and ultrasonic characteristics in patients with plaque psoriasis (PsP).
Patients And Methods: Demographic, clinical, and ultrasound data were collected from patients with PsP and PsA between May 2019 and December 2022.
Results: A total of 212 patients with PsP and 123 with PsA in the training cohort, whereas the validation cohort comprised 91 patients with PsP and 49 with PsA.
Objective: This study aimed to assess the role of synovial fluid (SF) CD4T, CD19B, follicular helper cells (Tfh), and cytokines in the pathogenesis of rheumatoid arthritis (RA).
Methods: This study enrolled 16 patients with RA and 8 patients with osteoarthritis (OA). The frequencies of the SF CD4 T, CD19 B, Tfh cells, and Tfh subsets were assessed using flow cytometry.
