A case-control study on the vitamin D receptor gene polymorphisms and susceptibility to pulmonary tuberculosis / 中华流行病学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the association between the genetic polymorphisms of VDR gene and susceptibility to pulmonary tuberculosis.</p><p><b>METHODS</b>Case-control study was conducted. PCR-RFLP technique was used to detect the C/T polymorphism in VDR gene. Information on related factors of tuberculosis was collected using a pre-tested questionnaire. Univariate and multivariate logistic analyses were conducted with SPSS software package.</p><p><b>RESULTS</b>A sample of 76 cases and 171 controls was studied. The genotype frequencies of VDR-FF, VDR-Ff and VDR-ff were 38.2%, 44.7%, 17.1% and 52.6%, 40.9%, 6.4% respectively. VDR-ff was significantly overrepresented in case group, the OR (95% CI) was 3.668 (1.483 - 9.071) when comparing with FF genotype. The significant association remained after adjusting BCG immunization and smoking, the OR (95% CI) was 3.036 (1.117 - 8.253).</p><p><b>CONCLUSION</b>The VDR-ff genotype might be associated with the susceptibility to pulmonary tuberculosis in Chinese Han population.</p>
