Sumario: | PURPOSE: Osteoporotic vertebral compression fracture (OVCF) is a common disease in the elderly, and genetic factors play a key role in its occurrence. The present study was conducted to investigate the association between interleukin-6 (IL-6) and the transforming growth factor (TGF-β) gene polymorphisms and the occurrence of thoracolumbar OVCF. PATIENTS AND METHODS: This case–control study recruited 146 patients with OVCF and 144 osteoporosis patients as the control group. Genotypes of the IL-6 rs1800796 and TGF-β rs1982073 were analyzed by sequencing. Genotype distribution and allelic frequencies were investigated by the χ(2) test. Odds ratios (OR) and 95% confidence intervals (CI) evaluated the relationship of IL-6 or TGF-β polymorphism and OVCF susceptibility. RESULTS: Allele G and genotype GG of IL-6 rs1800796 was more frequent in patients with OVCF (40.07% vs.28.47%; 19.18% vs.7.64%) compared with controls. GG genotype (OR=3.394, 95% CI=1.560–7.385, P < 0.001) and G allele (OR=1.680, 95% CI=1.187–2.376, P < 0.001) of IL-6 rs1800796 was significantly associated with increased risk of OVCF. What is more, CT and TT genotypes (41.78 vs.51.39; 19.86 vs.26.39) and allele T (40.75 vs 52.08) of TGF-β rs1982073 were less frequent in OVCFs, more common in controls and protective against OVCF risk (OR=0.436, 95% CI=0.228–0.835, P = 0.012; OR=0.615, 95% CI=0.443–0.855, P = 0.004). CONCLUSION: Our results suggest that the G allele and GG genotype of IL-6 rs1800796 may contribute to increased susceptibility to OVCF in elderly Chinese. In contrast, CT and TT genotypes and the T allele of TGF-β rs1982073 may contribute to lower susceptibility of OVCF. |
