Vancomycin-induced Severe asymptomatic Immune Thrombocytopenia; a rare cause

Abstract

Drug-induced immune thrombocytopenia is a challenging clinical problem that is often overlooked. Vancomycin is a rare cause of immune-mediated thrombocytopenia that can cause severe life-threatening bleeding in an acutely ill patient. The diagnosis requires a temporal relationship with the drug, exclusion of other common causes, and testing for vancomycin-induced platelet antibodies. Here we present a rare case of very severe but asymptomatic vancomycin-induced immune thrombocytopenia that resolved after discontinuation of vancomycin.
