Diagnosis and management of hemolysis, elevated liver enzymes, and low platelets syndrome.

Pregnancies complicated by hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome require a well-formulated management plan. The development of this syndrome after 34 weeks' gestation or with documentation of maternal or fetal compromise is an indication for delivery. Acute fatty liver of pregnancy, hemolytic uremic syndrome, and thrombotic thrombocytopenic purpura may present with signs, symptoms, and laboratory abnormalities that may be confused with HELLP syndrome. Thorough investigation is warranted because of the differences in proper management among these various complications of pregnancy. Expectant management in patients with HELLP syndrome remote from term and the use of corticosteroids to improve postpartum maternal outcome remain experimental.
