[PRE-ECLAMPSIA: A NEW TEST FOR AN OLD DISEASE].

In the western world, pre-eclampsia, diagnosed in 3-5% of pregnant women, is a major cause of maternal and fetal morbidity and mortality. Once pre-eclampsia is diagnosed, the only effective treatment is delivery. There are known historical risk factors for the development of pre-eclampsia, however only 30% of the women who will develop pre-eclampsia are identified based on their presence. Recently, new first trimester algorithms for the prediction of pre-eclampsia were developed, based on the observation that pregnant women who develop pre-eclampsia have imbalanced placental angiogenic factors and that failure of the trophoblastic migration may change the flow in the uterine arteries. These algorithms include maternal history and demographics, biochemical and clinical markers (mean arterial pressure, uterine artery flow PLGF, PAPP-A, PP-13). The combination of early diagnosis of a high risk group together with promising evidence that simple preventive measures, such as low-dose aspirin and calcium supplements may prevent pre-eclampsia or change its appearance leads to the idea that we are on the verge of a new era regarding detection and prevention of pre-eclampsia.
