Aim: The aim of this study is to investigate whether TNF-α polymorphisms are associated with the responsiveness to anti-TNF-α therapy in patients with spondyloarthropathy, psoriasis, and Crohn's disease. Methods: We conducted a meta-analysis on the association between the TNF-α polymorphisms and responsiveness of patients. Results: The meta-analysis indicated an association between the TNF-α-308 G allele (OR = 2.005; 95% CI: 1.417-2.838; p = 8.6 × 10-5), TNF-α-238 G allele (OR = 2.196; 95% CI: 1161-4.154; p = 0.016), and TNF-α-857 C allele (OR = 1.779; 95% CI: 1.130-2.802; p = 0.013) and response to TNF-α blockers in Caucasians. Conclusion: Individuals carrying the TNF-α-308 G,-238 G, or-857 C common alleles show better responses to TNF-α blockers than those with minor alleles in Caucasians.
