title: An unusual case of autoimmune hemolytic anemia in treatment naïve hepatitis C virus infection.
abstract: Hepatitis C virus (HCV) infection is emerging as a common and insidiously progressive liver condition. In more than one third of the cases, extrahepatic manifestations are seen in the course of the disease. Over the past decade, authors have reported membranous nephropathy, cutaneous vasculitis, idiopathic thrombocytopenic purpura, porphyria cutanea tarda and diabetes mellitus, among other extrahepatic manifestations of HCV infection. Recently, there have been a growing number of reports relating HCV infection to autoimmune cytopenias. Here, we report an unusual case of Coombs'-negative autoimmune hemolytic anemia (AHA) with severe autoimmune leukopenia and neutropenia, occurring simultaneously, in a patient with untreated hepatitis C infection. Mild cytopenias during chronic hepatitis C have been reported widely in the medical literature; however, severe cytopenias are seldom described and are usually seen only after or simultaneously with therapy.
