Pre-eclampsia (PE) is an obstetric disorder that may result in maternal and neonatal mortality and morbidity. Growing evidence indicates that cytokines, such as interleukins, are involved in the pathogenesis of this complication. Hence the current study aimed to assess the possible association between interleukin-1 receptor antagonist (IL-1Ra) VNTR polymorphism, and PE susceptibility in southeast Iranian women.Material and Methods:
The IL-Ra VNTR polymorphism was evaluated in 192 PE women and 186 age-matched normotensive pregnant women by the polymerase chain reaction method.Results:
The frequency of the A2 allele and the A2A2 genotype of IL-Ra VNTR polymorphism was significantly lower in PE patients compared to controls: therefore, A2 allele may play a protective role in PE development (odds ratio = 0.13 95% CI, [0.04–0.03]; P < 0.0001). In addition, there was no relation between the IL-Ra VNTR polymorphism and severity of the disease.Conclusion:
The A2 allele of the IL-Ra VNTR polymorphism could be a protective factor for PE susceptibility.
