Thrombotic Thrombocytopenic Purpura Masquerading as Hemolysis, Elevated Liver Enzymes, Low Platelets (HELLP) Syndrome in Late Pregnancy

Abstract

Thrombotic thrombocytopenic purpura can mimic HELLP syndrome late in gestation. Lack of response to dexamethasone within 12-24 hours and atypical relationships among laboratory values are two clues that thrombotic thrombocytopenic purpura may be the underlying pathology and that plasma exchange is emergently needed.
