marked elevation of blood pressure (>160/110 mmHg), severe proteinuria (>5 g/24 hours), or evidence of central nervous system (CNS) dysfunction (headaches, blurred vision, seizures, coma), renal dysfunction (oliguria or creatinine > 1.5 mg/dL), pulmonary edema, hepatocellular injury (ALT > 2-fold the upper limits of normal), hematologic dysfunction (platelet count < 100,000/L or DIC), or placental dysfunction (oligohydramnios or severe intrauterine growth restriction). The HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome is a special subgroup of severe preeclampsia and is a major cause of morbidity and mortality.
