Abstract:
التهاب المفاصل الرثوي هو احد الامراض المناعية الذاتية الالتهابية المزمنة الذي يتميز بالتهاب المفاصل المتماثل المستمر الذي يصيب عادة مفاصل اليدين والقدمين.تهدف هذه الدراسة الى التقصي عن العلاقة المحتملة بين مستويات الانترلوكين - 6 والانماط الجينية المتعددة | Rheumatoid arthritis (RA) is a chronic systemic inflammatory, autoimmune disease characterized by persistent symmetric polyarthritis that commonly affects joints of hands and feet.This study aims to investigate the possible association between interleukin - 6 (IL - 6) levels and ( - 174 G/C) IL - 6 promoter polymorphism in RA in Babylon Province. 60 RA patients and 60 healthy controls matched in age and sex were included in this case control study. Measurement of serum IL - 6 and serum anti cyclic citrullinated peptide (ACCP) antibodies were assayed using commercially available ELISA kit. Measurement of blood rheumatoid factor (RF) was assayed by use slide agglutination test for the qualitative and semiquantitative. Whereas, blood C - reactive protein (CRP) was determined using latex - enhanced nephelometry. Disease severity score of RA patients was determined by use DAS - 28. DNA was isolated from white blood cells (WBCs) and ( - 174 G/C) IL - 6 gene promoter polymorphism was determined by polymerase chain reaction - restriction fragment length polymorphism (PCR - RFLP) technique. the study was found significantly high levels of serum IL - 6 and ACCPA in untreated and in treated RA patients when compared to healthy controls. RF of patients with RA in the present study was found to be positive in 83.32% and negative in 16.67 % in overall RA patients, whereas was negative in 99% of healthy control. CRF of patients with RA in the present study was found to be positive in 78.4% and negative in 21.6 % in overall patients with RA, and was positive in 20% of healthy control. Correlation between DAS - 28 and IL - 6 levels in untreated and in treated RA patients were significant positive correlation. Correlation between IL - 6 and ACCPA in untreated and in treated RA patients were significant positive correlation. Correlation between DAS - 28 and ACCPA in untreated and in treated RA patients were significant positive correlation. The Genotype of ( - 174 G/C) IL - 6 gene promoter polymorphism and its percentage in patient found to be 80% GG,18.3% GC and 1.6% CC, whereas in healthy control 98.3% GG, 1.6% GC and 0% CC. Relation between both of IL - 6 levels and DAS - 28 with genotyping of ( - 174 G/C) IL - 6 gene promoter polymorphism in untreated and treated RA patients were found to be positive significant relation. The high levels of IL - 6, and its positive relation with DAS - 28 may suggest a possible role of IL - 6 in the pathogenesis of RA. Moreover, these biomarkers can be used as markers of disease activity in the diagnosis and treatment of RA. ( - 174G/C) IL - 6 polymorphisms are also associated with the RA risk, and the C allele of IL - 6 promoter polymorphisms has dramatically increased the susceptibility of RA in Babylon population. This finding suggests that the ( - 174 G/C) IL - 6 gene promoter polymorphism may also be used as another genetic marker for the onset and development of RA in Babylon population.
