BsmI (rs1544410) polymorphism located in intron 8 at the 3'-end of the vitamin D receptor (VDR) gene is known to be involved in the regulation of mRNA stability. Many studies evaluated the possible correlation between VDR BsmI polymorphism and the risk of pulmonary tuberculosis (PTB), and reported conflicting results. In the present study, an updated meta-analysis was performed to evaluate the above-said association. PubMed, Embase, and Google Scholar web-databases were searched for the relevant studies and a meta-analysis was performed by calculating pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) for all the genetic models. A total of 19 studies comprising 3644 controls and 2635 cases were included in the present study. Overall no association of PTB in allelic contrast (b compared with B: P=0.285; OR =0.909, 95% CI =0.762-1.083), homozygous (bb compared with BB: P=0.881; OR =0.975, 95% CI =0.700-1.359), heterozygous (bB compared with BB: P=0.834; OR =1.017, 95% CI =0.872-1.185), dominant (bb compared with BB + Bb: P=0.451; OR =0.954, 95% CI =0.843-1.079) and recessive (bb + Bb compared with BB: P=0.983; OR =1.002, 95% CI =0.868-1.156) genetic models in comparison with wild-type allele and genotype BB were observed. However, variant allele (b compared with B: P=0.001; OR =2.289, 95% CI =1.661-3.154) showed increased risk of PTB in Asians. In conclusion, VDR BsmI polymorphism is not a risk factor for PTB in overall population. However, this polymorphism may be interrelated to an increased risk of PTB amongst Asians.
