HBV and HCV Coinfection Associated with Warm-Type Autoimmune Hemolytic Anemia: A Case Report

Received/Geliş tarihi : December 15, 2012 Accepted/Kabul tarihi : April 30, 2013 To the Editor, The hepatitis virus may play an important role in autoimmune hemolytic anemia (AIHA). We herein report the case of a patient presented to our hospital with hepatitis B virus (HBV) and hepatitis C virus (HCV) coinfection who developed warm-type AIHA. The anemia improved, followed by declined viral levels, after rituximab plus antiviral therapy. To the best of our knowledge, this is the first reported case of HBV and HCV coinfection associated with warm-type AIHA. Written informed consent was obtained from the patient. A 66-year-old woman presented to the department of internal medicine of our hospital on 31 August 2010 with jaundice, inappetence, dizziness, palpitation, and fatigue. A month before admission, the patient complained of fatigue and palpitation, particularly aggravated after exercise, but she did not pay attention to it due to relief of these symptoms at rest. Three weeks later, the patient felt inappetence and dizziness, and her fatigue and palpitation did not go into remission at rest. Her daughter noticed her jaundice at this point and directed her to our hospital. She did not have past medical history of diffuse connective disease, lymphoproliferative disease, transfusion, favism, or allergic contact dermatitis. She had no related social history of cigarette, alcohol, or drug use. Her general physical examination revealed icteric skin and sclerae. Her abdominal examination showed a slightly increased spleen located in the left-upper abdomen. Complete blood count showed severe decrease of red blood cell count (1.39x1012/L), hemoglobin (53 g/L), and platelet count (73x109/L), in addition to significantly increased reticulocyte percentage (19%). Blood biochemistry revealed elevated total bilirubin (6.62 mg/dL), unconjugated bilirubin (4.95 mg/dL), and lactic dehydrogenase (528 U/L), with remarkable decrease of haptoglobin (0.3 g/L). The immunological test displayed
