Abstract: Preeclampsia (PE), a pregnancy complication characterized by increased blood pressure and proteinuria, is associated with significant maternal and neonatal mortality and morbidity worldwide. Recent studies suggest that women who suffered from PE are at increased risk of long term cardiovascular diseases (CVD) and that the link between these two entities could be explained by the metabolic syndrome (MS). As inflammation appears to be a major element involved as much in PE than in MS and CVD, our research aimed to investigate the potential association between genetic variations in candidate genes involved in the inflammatory process and PE risk in a study sample that included 307 women who suffered from PE and 603 matched controls. In this regard, we analysed known polymorphisms of interleukin-1α (IL-1α; 4845G> T), interleukin-6 (IL-6; -174C> G), interleukin-10 (IL-10; -1082A> G, -2849G> A), TNF-α (TNF-α; -308G> A, -857C> T) and TNF-α receptors (TNFRІ 36A> G, TNFRІІ 676T> G) genes. Our results suggest the presence of a dose-effect of the combination of genes involved in the inflammatory process on the risk of PE.
