We report five cases of vomiting asso ciated with a very important increase of maternal plasma uric acid(>595mmol /l,100mg /l)at the third trimester of pregnancy.In all cases,elevation was transitory and regressive with re-hydratation.Pregnancies proceeded normally to term and delivered healthy babies.An important rise of plasmatic uric acid during pregnancy can be fou nd in severe hyper-tensive disorders(preeclampsia,HELLP syndrome,acut e fatty liver).Nevertheless,it can be related to t ransient renal insufficiency without any severe pathology.In our five observations,digestive disorders seem to be the reason for this phenomenon and spontaneous pro gnosis was excellent in all cases.
