Objective: The aim of this study was to determine whether the functional chemokine receptor 5 delta32 (CCR5-Δ32) polymorphism confers susceptibility to rheumatoid arthritis (RA) and juvenile idiopathic arthritis (JIA). Methods: Meta-analysis was conducted on associations between the CCR5-Δ32 polymorphism and RA and JIA using (1) allele contrast and (2) the recessive, (3) the dominant, and (4) the additive models. Results: Eleven population comparisons based on the data obtained from nine studies involving 13,412 subjects (RA 3,848, controls 4,095; JIA 1,599, controls 3,870) were considered. In all study subjects, meta-analysis showed a significant negative association between RA and the CCR5-Δ32 allele (OR = 0.771, 95 % CI = 0.694-0.866, p = 6.5 9 10-7). Stratification by ethnicity indicated a significant association between the CCR5-Δ32 allele and RA in Europeans (OR = 0.8001, 95 % CI = 0.709-0.904, p = 3.2 9 10-5). Meta-analysis showed associations between the CCR5-Δ32 allele and JIA in Europeans and oligoarticular type (OR = 0.797, 95 % CI = 0.690-0.921, p = 0.002; OR = 0.475, 95 % CI = 0.352-0.693, p = 9.5 × 10-8). Conclusions: This meta-analysis demonstrates that the CCR5-Δ32 polymorphism may confer susceptibility to RA and JIA in Europeans, and suggests that the CCR5-Δ32 allele protects against the development of RA and JIA.
