The association between CD14 gene C-159T polymorphism and tuberculosis (TB) susceptibility remains inconclusive. To derive a more precise estimation of the correlation, we performed a meta-analysis summarize the possible at a systematic manner. PubMed, HighWire and ScienceDirect databases covering all papers (up to November 2012) were searched. Statistical analyses were conducted by Rev-Man and STATA. Random- and fixed-effect models were used to estimate pooled odds ratios (ORs) and 95?% confidence intervals (CIs), based on between-study heterogeneity. Eight published case–control studies investigating the relationship between C-159T polymorphism in CD14 gene and TB susceptibility were included. Results showed that individuals with T allele have an increased risk of TB compared with those with C allele (OR (95?% CI) was 1.52 (1.11, 2.08) for TT vs. TC?+?CC, P?P?=?0.04). When stratified by ethnicity, variant TT homozygote carriers had an 86?% increased risk of TB in Asians (OR (95?% CI) was 1.86 (1.57, 2.20) for TT vs. TC?+?CC, P?P?=?0.61). This meta-analysis suggests that C-159T polymorphism in CD14 gene is associated with increased risk of TB, especially in Asians, but not in Caucasians.
