Associations between functional FCGR2A R131H and FCGR3A F158V polymorphisms and responsiveness to TNF blockers in spondyloarthropathy, psoriasis and Crohn's disease: a meta-analysis

초록

Aim: The aim of the current study was to investigate whether FCGR polymorphisms are associated with responsiveness to anti-TNF-alpha therapy in patients with spondyloarthropathy, psoriasis, and Crohn's disease. Materials & methods: We conducted a meta-analysis to evaluate the association between the functional FCGR3A F158V and FCGR2A R131H polymorphisms and responsiveness to TNF blockers. Results: The meta-analysis indicated that responsiveness to TNF blockers was associated with the FCGR3A V allele (odds ratio: 3.308; 95% CI: 1.053-10.39; p = 0.040) and the FCGR2A RR + RH genotype (odds ratio: 3.904; p = 0.027) in patients with a follow-up time of >= 6 months. Conclusion: FCGR3A V and FCGR2A R allele carriers show better responsiveness to anti-TNF-alpha therapy in patients with follow-up times >= 6 months.
