[Differences and similarities of preeclampsia and gestational hypertension].
Current criteria regarding hypertension in pregnancy consider two distinct types: gestational hypertension (pure type) and preeclampsia-eclampsia syndrome, the latter with albuminuria as a mandatory clinical fact. However, reports of lasts years show that a 15 to 46% of cases classified as pure type gestational hypertension evolve to a preeclamptic state, underlying the possibility that both clinical conditions represent diferent stages of the same disease. On the other hand, albuminuria may not be present in severe cases of pregnancy-related hypertensive disorders such as HELLP syndrome or eclampsia. It follows that if albuminuria is not necessary to establish the most severe forms of the disease, must the non-albuminuric hypertensive-type still be considered as a diferent diagnosis? This report reviews the medical literature on the subject, stressing similarities and diferences of both conditions in order to reflect about the need to change the classification concepts pregnancy-related hypertensive entities.
