Abstract: | OBJECTIVES: To investigate whether hypertensive disorders of pregnancy alter the maternal and fetal leptin levels. METHODS: Fifty primigravidas between 28 and 34 weeks of gestation were divided into three groups: group A consisted of 17 normal pregnant women with a mean gestational age of 31 weeks, group B consisted of 15 women with gestational hypertension without proteinuria with a mean gestational age of 30 weeks and group C consisted of 18 pre-eclamptic women with a mean gestational age of 31 weeks. RESULTS: The pre-eclamptics had significantly higher serum leptin levels than those in normal pregnancies (p<0.001) but no difference was noted between normal and gestational hypertensive pregnancies. Pre-eclamptic women had significantly higher umbilical vein leptin levels (4.68+/-1.66ng/ml) compared to normal pregnancies (1.92+/-0.71ng/ml) and those with gestational hypertension (2.47+/-0.81ng/ml). CONCLUSIONS: Pre-eclampsia is associated with an increase in maternal plasma leptin levels and fetal of leptin production increases in gestational hypertension and even more in pre-eclampsia. |
