Abstract

The aim of this study was to determine whether toll-like receptor (TLR) polymorphisms confers susceptibility to vasculitis. A literature search was conducted using the PubMed and Embase. A meta-analysis on the associations between the TLR4 Asp299Gly polymorphisms and vasculitis was carried out using allele contrast, dominant, and codominant models and a systematic review of other TLR polymorphisms. Fourteen studies involving 2,064 patients and 2,481 controls were included in this systematic review, which comprised nine on Behcet's disease (BD), three on giant cell arteritis (GCA), and one on Henoch-Schenlein purpura (HSP). Meta-analysis of six studies showed a significant association between the Gly/Gly+Gly/Asp genotype of the TLR4 Asp299Gly polymorphism and vasculitis and GCA (Odds ratio [OR] = 1.368, 95 % confidence interval [CI] = 1.300-1.815, p = 0.030; OR = 1.523, 95 % CI = 1.099-2.112, p = 0.012). Under a random effects model, the adjusted ORs calculated using the trim and fill technique revealed an association between the Gly/Gly+Gly/Asp genotype of the TLR4 Asp299Gly polymorphism and vasculitis (OR = 1.544, 95 % CI = 1.091-2.185, p < 0.05). Stratification by vasculitis type using the codominant model showed the trend for the association with GCA (OR = 1.569, 95 % CI = 0.970-2.538, p = 0.066). There were three studies on the TLR2 Arg753Gln polymorphism and two on the TLR4 Thr399Ile polymorphism; no association with vasculitis was evident. Among the TLR2, TLR7, and TLR9 polymorphisms included in this review, one Asian study revealed a significant association between the TLR7 rs5743733 and rs3853839 with BD (p = 0.002, 0.036) and one Asian study showed an association of TLR9 rs352140 with BD (p = 0.009). This meta-analysis demonstrates that the TLR4 Asp299Gly polymorphism may confer susceptibility to GCA. The review of published data suggests that other TLR polymorphisms such as TLR7 and TLR9 may play a role in vasculitis.
