Abstract
OBJECTIVES: To analyze the contribution of maternal eNOS-Glu298Asp genotypes and also the association with fetal genotypes to the development of preeclampsia, prognosis, and maternal dyslipidemia. METHODS: Sixty-nine pairs of preeclamptic mothers/newborns and 94 pairs of normotensive mothers/newborns were genotyped for eNOS-Glu298Asp using PCR-RFLP methods. RESULTS: Women carriers of at least one Asp298 allele had a 1.53-fold (p = NS), 1.88-fold (p = NS), and 2.08-fold (p = .05), respectively, increased risk to develop PIH, mild, or severe preeclampsia. If both the mother and the newborn were carriers of the Asp298 allele, the risk for preeclampsia was 5.09-fold higher (p < .001). Preeclamptic women with severe preeclampsia had significantly higher cholesterol (mg/dl, 287.23 ± 43.01 versus 235.36 ± 45.01, p = .02) and LDL (mg/dl, 194.9 ± 42.8 versus 144.98 ± 54.84, p = .04) levels and lower HDL levels (mg/dl, 32.12 ± 5.48 versus 57.84 ± 20.59, p = .02) compared to noncarriers. Also, higher LDL levels (mg/dl, 188.76 ± 46.61 versus 136.75 ± 41.85, p = .03) and lower HDL levels (mg/dl, 32.8 ± 5.64 versus 61.06 ± 22.45, p = .02) were found in preeclamptic women with severe preeclampsia whose newborns were carriers of the Asp298 allele. CONCLUSIONS: The eNOS-Glu298Asp variant (in mothers and newborns) in association with dyslipidemia could affect bioavailability of NO and could represent an increased risk for preeclampsia.
