This study determined whether tumor necrosis factor alpha (TNF-α) and Interleukin-10 (IL-10) polymorphisms are associated with susceptibility to dengue. a systematic review with meta-analysis was conducted of the associations between the TNF-α (-308G/A) and IL-10 (-819C/T) polymorphisms and dengue. A total of eight case-controls studies involving 384 individuals with symptomatic dengue, 571 individuals with dengue hemorrhagic fever, and 995 healthy controls were considered in the meta-analysis. There was no significant association between TNF-α (-308G/A) and IL-10 (-819C/T) polymorphism and dengue in overall population. However, stratifying meta-analysis by groups, the meta-analysis revealed association between the TNF-α -308 G/G (OR: 1.62, CI: 1.02-2.57, p = 0.04) genotype and allele G (OR: 1.62, CI: 1.04-2.55, p = 0.03) that confers susceptibility to symptomatic dengue, while the TNF-α -308 G/A genotype (OR: 0.69, CI = 0.39-0.99, p = 0.04) and allele A (OR: 0.64, CI: 0.41-1.00, p = 0.05) confers protection to symptomatic dengue. No difference was observed for the TNF-α (-308) and IL-10 (-819C/T) polymorphisms in the comparisons of hemorrhagic dengue versus control and hemorrhagic dengue versus symptomatic dengue. This meta-analysis showed that TNF-α (-308) polymorphism is associated with dengue symptomatic susceptibility.
