HELLP syndrome - a syndrome of hemolysis, elevated liver enzymes and low platelet count - complicating preeclampsia-eclampsia

Abstract

The course of preeclamptic/eclamptic patients may be complicated by HELLP syndrome, a syndrome of intravascular hemolysis (H), elevated liver enzymes (EL) and low platelet count (LP). These patients typically present at early third trimester with epigastric or right upper quadrant pain, nausea and vomiting. They may present without the clinical signs of preeclampsia (hypertension and proteinuria or edema), thus an initial wrong nonobstetric diagnosis is not uncommon. The most frequent maternal complication is intravascular coagulopathy (30%). Placental abruption and acute renal failure are also common. Ten cases of maternal deaths were reported among 295 cases reviewed in the English language literature, while the perinatal mortality rate was 226/1000. The grave prognosis for mother and fetus warrants physician awareness in order to accomplish early diagnosis and proper management. This paper is a review of the literature in English.
