Article Abstract

Methotrexate at low doses (5-25 mg/week) is first-line therapy for rheumatoid arthritis. However, there is inter- and intrapatient variability in response, with contribution of variability in concentrations of active polyglutamate metabolites, associated with clinical efficacy and toxicity. Prescribing remains heterogeneous across population groups, disease states and regimens. This review examines current knowledge of dose-response of oral methotrexate in the setting of rheumatoid arthritis, and how this could help inform dosage regimens.

Background: Interleukin-1 receptor-associated kinase1 (IRAK1) plays a considerable role in the inflammatory signaling pathway. The current study aimed to identify any association between (rs1059703) single nucleotide polymorphism (SNP) and vulnerability to rheumatological diseases in the pediatric and adult Egyptian population.

Patients And Methods: The current study included four patient groups: adult Systemic lupus erythematosus (SLE), Rheumatoid arthritis (RA), juvenile systemic lupus erythematosus (JSLE), and juvenile idiopathic arthritis (JIA).

Background: Celiac disease (CeD) has shown an association with autoimmune disorders including vitiligo and alopecia areata (AA). Ritlecitinib, a JAK3 and TEC kinase family inhibitor, has been approved for treatment of patients with AA and is in late-stage development for vitiligo. Ritlecitinib inhibits cytotoxic T cells, NK cells, and B cells which play a role in the pathogenesis of CeD.
