Background: In primary healthcare settings, chronic low back pain (cLBP) is a widespread health issue with a great global impact.
Methods: A cross-sectional analytical study was performed on 918 adults attending primary healthcare settings in Makkah, Saudi Arabia, to estimate the cLBP prevalence, its effect on health-related quality of life (QOL), and predictors of subsequent disability. The visual analog scale of pain (VAS), World Health Organization Quality of Life Scale (WHO-QOL), and Oswestry low back pain disability index (ODI) were used to assess back pain severity, impact on QOL, and physical disability, respectively.
Objectives: Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by T-cell immune-dysregulation and loss of tolerance to self-antigens. CTLA-4 and PTPN-22 are involved in the inhibition of T-lymphocytes activation. IL-37 is an anti-inflammatory cytokine that suppresses innate immunity.

The triad of autoimmunity, genetics, and environment is the key player in RA pathogenesis. We intended to investigate gene expression of C-C Chemokine Ligand 2 (CCL2), protein tyrosine phosphatase non-receptor type 22 (PTPN22), and Cytotoxic T-lymphocyte associated protein 4 (CTLA-4) in RA patients versus controls, and its correlation with the activity of the disease.

Methods: A prospective, open-label study was carried out on adult females with moderate-to-severe rheumatoid arthritis. Patients were randomly assigned to receive either intravenous tocilizumab or abatacept treatment.
