بررسی ارتباط میزان BhCG سرمی میانه بارداری با بروز پره اکلامپسی

The pre-eclampsia/eclampsia is one of the commonest conditions peculiar to pregnancy, to describe the occurrence of hypertension, proteinuria and edema in pregnancy. It is about seven times more frequent in first gestation and uncommon before 20 week's gestation. Serum BhCG levels were prospectively determined in 260 midtrimester singleton pregnancies where admitted from October 1999 until September 2000 at Mirza Kouchak Khan hospital, prenatal clinic. Obstetric chart review was undertaken after delivery to identify cases in which pre eclampsia developed. The median maternal age was 26.0 years, and the median gestational age at the time of blood collection was 19.0 weeks. Of these, 17 cases (6.5 percent) had pre eclampsia. The median level of the BhCG was 35060.5 mlu/ml in those with pre eclampsia, whereas that in those without pre eclampsia was 33755.1 mlu/ml. The difference was not significant (P=0.28). Although elevated midtrimester serum BhCG levels in clinically normal patients was reported in severaly pre eclampsia women, this is not a good test for early detection of mild pre eclampsia.
