Introduction HELLP syndrome complicates 0.5–1% of all pregnancies, and among pregnant women with PE – 2–20% and is characterized by high maternal and perinatal mortality. Objective To study modern features of the current, maternal and perinatal outcomes in pregnant women with HELLP-syndrome. Methods 28 stories of pregnant women with HELLP syndrome were analyzed. Results and its discussion In 71.4% of cases, the diagnosis of HELLP syndrome was made during pregnancy, and 28.5% after delivery. In women with severe preeclampsia, 11% were observed. HELLP syndrome was observed more often in primiparous women older than 30 years. In HELLP-syndrome: chronic arterial hypertension (28.5%), IVF (7.1%), history of PE (10.7%), genetic thrombophilia (14.2%), antiphospholipid syndrome (7.1%), chronic pyelonephritis (21.4%). Only 32,1% of HELLP-syndrome was combined with severe AH (BP > 160/110 mmHg). In 25% of patients, mild proteinuria is found, and 10.7% is not detected at all. Clinical symptoms were pain in the right upper quadrant (46.4%), weakness (21.4%), headache (17.8%), vomiting (17.8%), nausea (14.2%, increase in hepatic Enzymes were detected in 53.5% of cases, thrombocytopenia in 64.2%, hemolysis was detected in 7.1% of cases, an increase in LDH more than 600 U/L in 39.2% of cases. Increase in hepatic enzymes – AST more than 70 U/l – in 78.5% of cases, ALT more than 150 U/L – 60.7% The classical manifestation of HELLP syndrome was noted only in 64.2% of cases, monosymptomatic course in 35.7%. Circulation of lupous anticoagulant (BA) in 7.1% of cases. The perinatal complications:preterm labor (85.4%), IUGR (57.1%), placental insufficiency (53.5%) are exceptionally high. Antenatal fetal death is revealed in 21.4% of cases. Maternal complications:hepatic insufficiency (3.5%), acute renal failure (3.5%), cerebral edema (3.5%), pulmonary edema (3.5%), subcapsular hematoma of the liver (3.5%).
