Preeclampsia (PE) is one of the most serious disorders of human pregnancy with a high rate of mortality for the fetus and mother. Several etiological factors are involved in the onset of this disease. Upregulation of IL-27 has been reported in placental tissue recovered from preeclamptic women, but the role of IL-27 has not yet been investigated in PE. The aim of the study was to investigate the association of IL-27 rs153109 and rs17855750 gene polymorphisms with PE; also, protein levels and susceptibility and severity of PE in Iranian women were evaluated. This case-control study was performed on 199 PE patients and 228 healthy women as the control group. IL-27 rs153109 and rs17855750 SNPs were genotyped using a PCR-RFLP method. Moreover, the levels of IL-27 were determined in 40 PE and 45 healthy women using ELISA method. Statistical analysis indicated that there were no differences in genotype, allele and genotype combination frequencies in the SNPs between cases and controls. The plasma level of IL-27 was elevated in the mild form of the disease compared with controls (p-value: 0.006). The effect of IL-27 in preeclampsia is not due to the studied cytokine polymorphisms, but the level of IL-27 might be associated with the severity of preeclampsia in Iranian women. Show less
