Methods: Relevant publications were retrieved by searching databases. Odds ratios (ORs) and standard mean differences (SMDs) with 95% confidence intervals (95% CIs) were used to assess the association of the TNF-α gene and cytokine with IS, respectively. The Cochrane Q test and I2 statistic were used to test heterogeneity. Subgroup analysis and publication bias were performed.
Results: 25 and 9 articles examined the association of polymorphisms and levels of the TNF-α with IS risk, respectively. Rs1800629 polymorphism was associated with IS susceptibility (OR (95% CI) =0.82 (0.72, 0.95)), especially in Asians (OR (95% CI) =0.75 (0.63, 0.89)); and rs1800610 was associated with IS susceptibility in Asians patients (OR (95% CI) =1.54 (1.31, 1.80)). While rs361525, rs1799964 and rs1799724 polymorphisms were not associated with IS susceptibility. The TNF-α level was elevated in IS patients (SMD (95% CI) =0.65 (0.29, 1.01)) including Asians (SMD (95% CI) =1.26 (0.49, 2.03)) and Caucasians (SMD (95% CI) =0.26 (0.03, 0.49)). In addition, increased level occurred in patients' serum (SMD (95% CI) =0.54 (0.08, 1.01)).
Conclusions: Rs1800629 and rs1800610 polymorphisms were elucidated to be a protective factor for IS (especially in Asians) and a risk factor for Asians patients, respectively. The TNF-α level was elevated in IS, indicating that TNF-α plays an important role in the pathogenesis of IS and is a promising therapeutic target for IS.
