Association of CCR5, CCR2 and SDF1 gene polymorphisms with HIV-1 infection in Chinese population: a meta-analysis / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To explore the association of CCR5&delta;32, CCR2-64I and SDFl-3 A gene polymorphisms with HIV-1-infection in Chinese population.</p><p><b>METHODS</b>A meta-analysis was performed to identify case-control studies of CCR5&delta;32, CCR2-64I and SDFl-3 A polymorphisms from the literatures.</p><p><b>RESULTS</b>Fourteen studies of CCR5&delta;32 were found, involving a total of 1607 cases and 1632 controls. Compared with the wild-type homozygote wt/wt, the pooled odds ratios (95%CI) of wt/mt, mt/mt, and wt/mt+mt/mt genotypes of CCR5&delta;32 gene polymorphisms were 1.156 (0.808, 1.654), 0.997 (0.198, 5.022), and 1.149 (0.808, 1.634), respectively. Twelve studies of CCR2-64I were identified, including 1415 cases and 1239 controls. Compared with the wild-type homozygote wt/wt, the pooled odds ratios (95%CI) of wt/mt, mt/mt, and wt/mt+mt/mt genotypes of CCR2-64I gene polymorphisms were 1.005 (0.844, 1.197), 1.191 (0.808, 1.754), and 1.028 (0.870, 1.214), respectively. Ten studies of SDFl-3 A were found, involving 1179 cases and 1003 controls. Compared with the wild-type homozygote wt/wt, the pooled odds ratios (95%CI) of wt/mt, mt/mt, and wt/mt + mt/mt genotypes of SDF1-3 A gene polymorphisms were 1.010 (0.830, 1.228), 1.188 (0.860, 1.643), and 1.038 (0.861, 1.250).</p><p><b>CONCLUSION</b>CCR5&delta;32, CCR2-64I and SDFl-3 A gene polymorphisms do not show strong correlations to HIV-1-infection in Chinese population. These 3 genes may not have protective effect against HIV-1 infection in Chinese population, suggesting the susceptibility of Chinese population to the infection.</p>
