|Resumo:||Despite being the subject of several independent studies, the relationship between Interleukine-6 (IL-6) polymorphisms and kidney graft outcome continue to be plagued by contradictory conclusions. In this meta-analysis we collect all the relevant studies to further clarify the association of IL-6 genotypes and Chronic Nephropathy of the Graft (CNG). Relevant published data was retrieved through Medline with references to kidney transplant outcome and IL-6 polymorphisms. Odds ratios (OR) with 95% confidence intervals (CI) were used to assess the strength of the association. Z test was used to determine the significance of the pooled OR. Statistical heterogeneity was measured using the Q statistic. A total of 6 studies, including 474 transplanted patients with CNG and 731 transplanted patients as control group with stable graft function, were collected. The distribution of IL-6 polymorphims was evaluated and no heterogeneity was observed among individual estimates. Original data was combined using the fixed-effects model. For the total population, we found that G/G and G/C IL-6 genotypes were less common in the CNG group than in the control group with an OR of 0.61, (95 % CI=0.42–0.87), and p=0.006, which shows a protective association of IL-6 high producers genotypes in the CNG group. IL-6 is both a major proinflammatory cytokine and an important anti-inflammatory mediator, these complex actions would yield variable effects on atherosclerosis and cardiovascular risk profile in kidney transplant recipients. Our comprehensive meta-analysis indicated that there is sufficient evidence to demonstrate an association between the IL-6 polymorphisms and CNG after kidney transplantation.|
