Association between interleukin-1 receptor associated kinase 1 rs3027898 A/C gene polymorphism and rheumatoid arthritis.

ABSTRACT: Rheumatoid arthritis (RA) is a systemic autoimmune disease predominantly involving the synovial joints and affects up to 1% of adults worldwide. The aim of the present study was to determine whether the interleukin-1 receptor (IL1R)-associated kinase (IRAK1) rs3027898 gene polymorphism confers susceptibility to RA in a sample of patients from Iran. This gene encodes IRAK1, one of two putative serine/threonine kinases that associates with IL1R upon stimulation. IRAK1 is partially responsible for IL-1-induced upregulation of the transcription factor, nuclear factor-?B. The present case-control study was performed on 120 patients with RA and 120 healthy individuals. Genomic DNA was extracted from whole blood, and the gene polymorphism was evaluated using a tetra-primer amplification refractory mutation system-polymerase chain reaction method. The results demonstrated that there was no association between IRAK1 rs3027898 CA genotype and the risk of RA in women (odds ratio=0.72, 95% confidence interval=0.41-1.49; P=0.446). Further studies with larger sample sizes and different ethnicities are required to validate the present findings.

Project description:ObjectivesRheumatoid arthritis is a chronic inflammatory autoimmune disease. This study aimed to determine the association of interleukin-17A-197G/A polymorphism with rheumatoid arthritis in Sudanese patients.MethodsA case-control study was conducted between March and December 2018. Clinical and demographic data of the study participants were collected and analyzed. Polymerase chain reaction restriction fragment length polymorphism molecular technique was done to investigate interleukin-17A-197G/A polymorphisms. All statistical tests were considered statistically significant when p < 0.05.ResultsThe study population included 266 participants aged between 1 and 85 years, with an average of 40 years, classified into 85 (31.2%) cases (mean age 48.5 ± 11.3 years), and 181 (68.8%) controls (mean age 35.3 ± 15.9 years). The interleukin-17A homozygote AA genotype was more frequent among the control group compared to the case group; 95 (52.5%) and 7 (8.2%), respectively. The homozygote GG and the heterozygote AG genotypes were proportionally not different among the cases and control groups; 13 (54.2%) and 11 (45.8%), and 65 (46.4%) and 75 (53.6%), respectively. According to the distribution of interleukin-17A genotypes, a statistically significant difference was observed among cases with the interleukin-17A AA and AG genotypes, p values 0.001 and 0.004, respectively. For the association interleukin-17A genotypes and family history a negatively significant association was reported (95% confidence interval, -0.219, p value = 0.001). There was also a negatively significant association of interleukin-17A genotypes and anti-cyclic citrullinated peptide (95% confidence interval, -0.141, p value = 0.002).ConclusionThis study is the first study in Sudan established the association between interleukin-17A-197G/A (rs2275913) polymorphisms and susceptibly to rheumatoid arthritis. These findings appeal for further research in Sudan to investigate the exact role of IL-17A in immunopathology and disease severity among Sudanese rheumatoid arthritis.
