Association of Interleukin-17 and ACCP levels with Rheumatoid arthritis patients and Control Groups

Background: Rheumatoid arthritis (RA) represents the prevailing form of chronic inflammatory polyarthritis, characterized by an autoimmune response directed against citrullinated antigens and subsequent synovial joint destruction. The susceptibility to RA appears to be influenced by a complex interplay between a specific immune response to various environmental factors and a favorable genetic predisposition. IL-17 Association with Diseases found to be elevated in various chronic inflammatory conditions including  RA especially in cases resistant to anti-TNF therapy. Aim : To investigate the value of IL-17 and ACCP levels with study groups as well as the association of chronic periodontal disease as an environmental risk factor of RA. Methods : This case-control study involved a total of 140 participants were enrolled, with 70 individuals meeting specific criteria and serological testing confirming their RA diagnosis, while the remaining 70 served as healthy controls.The study involved the collection of blood samples from the participants. Various measurements and tests were conducted, including the assessment of disease activity using the Disease Activity Score (DAS28-ESR) and erythrocyte sedimentation rate (ESR), detection of RF through latex agglutination, quantification of anti-cyclic citrullinated peptide (ACCP) and interleukin-17 (IL-17) levels via enzyme-linked immunosorbent assay (ELISA). Results : RA patients exhibited substantially higher values  for ESR, RF, ACCP compared to the control group. Also IL-17 substantially higher values  for RA patients  Notably, the p-values for ESR, ACCP, and IL-17 were 0.0001, 0.02, and 0.0001, respectively, indicating strong statistical significance. patients who had gum problems were 43(61.4 %) while the control group was 9 (12.5%) had a gum problem Statistically, parameter had significant differences (p.value=0.0001).
