  • Title: Association between Tumor Necrosis Factor-308 G/A Polymorphism and Chronic Obstructive Pulmonary Disease Risk in Chinese Population: Evidence from a Meta-Analysis.
    Author: Shi C, Zhao H.
    Journal: Clin Lab; 2019 Oct 01; 65(10):. PubMed ID: 31625355.
    Abstract:
    BACKGROUND: Association studies of tumor necrosis factor (TNF)-308 G/A (rs1800629) polymorphism and chronic obstructive pulmonary disease (COPD) have shown inconsistent and contradictory results among different populations. In the present study, a meta-analysis was performed to evaluate the association between TNF-308 G/A polymorphism and COPD susceptibility in Chinese population. MATERIALS AND METHODS: Systemic assessment was performed for the published studies from PubMed, Embase, Web of Science, the Cochrane Library, Wanfang Data, and CNKI prior to July 2018. Odds ratios (ORs) with their 95% confidence intervals (CIs) were pooled using STATA software. RESULTS: A total of eighteen studies comprising 1,817 COPD cases and 2,056 controls were included in this meta-analysis. Overall, significant results were obtained between TNF-308 G/A polymorphism and COPD risk in Chinese population (A vs. G, OR = 2.45, 95% CI: 1.93 - 3.11; AA vs. GG, OR = 4.53, 95% CI: 2.67 - 7.68; AA vs. GA + GG, OR = 3.74, 95% CI: 2.21 - 6.33; AA + GA vs. GG, OR = 2.53, 95% CI: 1.97 - 3.26) under allele and homozygote models as well as recessive and dominant models. In the subgroup analyses, TNF-308 G/A polymorphism was significantly associated with increased COPD risk both in North China and South China, as well as in population-based studies. CONCLUSIONS: This meta-analysis indicates that TNF-308A/G polymorphism may contribute to individual suscepti-bility to COPD in Chinese population.
