Background Rheumatoid arthritis is a complex multifactorial chronic disease, the importance of human leukocytic antigen (HLA) as a major genetic risk factor for rheumatoid arthritis was studied worldwide. The objective of this study is to identify the association of HLA-DRB1 subtypes with rheumatoid arthritis and its severity in Kurdish region. Methods A case–control study recruited 65 rheumatoid arthritis patients and 100 healthy individuals as control group all over the Kurdistan region/Iraq. Both patient and control groups are genotyped using polymerase chain reaction with sequence specific primer. Anti-CCP antibodies were measured by ELISA test. Rheumatoid factor, C-reactive protein, and disease activity score 28 which measured by DAS-28 values were calculated. The DAS-28 was used to assess the clinical severity of the patients. Results HLA-DRB1-0404 and HLA-DRB1-0405 frequencies showed a strong association with disease susceptibility (P < 0.001). The frequency of HLA-DRB1-0411 and HLA-DRB1-0413 were significantly higher in control group (P < 0.001). The frequency of rheumatoid factor and Anti-CCP were significantly higher among shared epitope-positive patients compared to shared epitope-negative patients (P < 0.001). Regarding the disease activity by DAS-28, rheumatoid arthritis patients didn’t show significant difference between the shared epitope-positive and shared epitope-negative patients. Conclusions HLA-DR0404 and HLA-DR0405 alleles are related to RA, while HLA-DR1-0411 and HLA-DRB1-0413 protect against RA in the Kurdistan region in the North of Iraq.

Background/Aims In November 2019, there were abundant cases of COVID-19 for which the first case was reported in Wuhan, China. Cytokine storm syndrome is the severe immune reaction that may cause a severe tissue response in COVID-19 patients. Colchicine has an important role in inhibiting activation of NLRP3 inflammasome that predispose to decrease cytokine production. This study aimed to evaluate whether colchicine is effective in treatment of COVID-19 patients or not. Methods A randomized, open labelled, clinical trial of colchicine for the treatment of COVID-19, allocated between 8th May to 18th June 2021. Patients with mild, moderate, or severe COVID-19 infection; confirmed by real time PCR (RT-PCR) and/or lung involvement confirmed by computed tomography scan compatible with COVID-19. The colchicine tablet dosage was 0.5mg twice daily for 14 days added to the standard treatment versus control group who received standard treatment without colchicine, with the trial registration ID: NCT04867226. The study was conducted in Erbil City, Iraq with the endpoints being clinical, laboratory parameters duration of hospitalization and side effects. Results 80 patients participated in the study. Fewer patients in the colchicine group had musculoskeletal symptoms (17.5%, p: 0.001) in comparison to the patients, who received control treatment. The serum ferritin level in most of patients who treated with colchicine returned to normal in contrast to the control group, whose serum ferritin level was still high (p: 0.041). Similarly, the average of CRP and D-dimer after treatment among the colchicine group participants was significantly lower than the control group, the P-values were 0.011 and 0.043, respectively. The colchicine group patients stayed for a shorter duration at the hospital (18.4 days) compared to the control group (24.24 days). P-value was 0.009. In addition to that the response and cure rate were higher in the colchicine group (56%) in the comparison to control group (43.1%) Table 1: Laboratory Parameters with musculoskeletal symptoms and duration of hospitalization of both Treatment Regimens.. Conclusion The colchicine drug can be effective in treating patients with COVID-19 infection by improving musculoskeletal symptoms and inhibiting inflammatory biomarkers; it is also effective in reducing duration of hospitalization.

Introduction: Rheumatoid arthritis (RA) is a long-term autoimmune disorder that primarily affects joints. Lower Vitamin D (Vit. D) levels correlate with more severe clinical manifestations in RA and other rheumatic diseases. IL-17A promotes inflammation by inducing various proinflammatory cytokines and chemokines. In this study, we evaluated the association between Vitamin. D and IL-17 in osteoporosis in Rheumatoid Arthritis in Kurdish nation / Iraq. Objective: Blood samples from rheumatoid arthritis (RA) patients were used to measure the levels of the inflammatory cytokine IL-17 and the Vit. D precursor 25(OH)D and bone loss in patients with RA in this study. Methods: In this study, 40 healthy controls were included in the research, which comprised 100 new cases of RA. ELISA was used to measure the level of serum 25(OH)D and IL-17. Moreover, DXA was used to assess average bone mineral density (BMD). Results: We discovered no difference between the two groups in terms of age or gender. This means that compared to the control group, the 25(OH)D serum levels in the RA group were lower (P 0.01; 16.85+8.7 nmol/l vs. 39.95 (-+9.8)). IL-17 serum levels were highly and negatively associated with 25(OH)D levels in arthritic patients. A comparison of 25(OH)D levels in patients with osteoporosis and osteopenia and those with BMD was also performed. Conclusion: Bone loss and IL-17 have been associated with reduced Vit. D levels in patients with rheumatoid arthritis; a lack of Vit. D may have a role in developing the disease, according to the data presented in this study.
