OBJECTIVE: To determine the prevalence of hepatitis C virus (HCV) antibody in patients with sickle cell disease and to analyze the nature of chronic liver disease in these patients.
METHODS: A total of 99 patients attending a comprehensive sickle cell and thalassemia program at the Interfaith Medical Center, Brooklyn, NY, participated in the study. Eighty-five patients had sickle cell anemia (ss), eight had sickle C disease (sc), and six had sickle B thalassemia. History of blood transfusion, i.v. drug use, homosexuality, and alcohol abuse was obtained with a questionnaire and chart review. All patients were screened for HCV antibody by a first generation enzyme-linked immunosorbent assay. All positive results were confirmed with radioimmunoblot assay II (RIBA II). Patients were also checked for the presence of hepatitis B surface antigen. ALT levels were measured, and percutaneous liver biopsies were performed in patients positive for HCV antibody and greater than 1.5 times the normal ALT levels.
RESULTS: Antibody to HCV was detected in 10/99 patients (10.10%). Seven of 30 patients (23.33%) who received more than 10 U of packed red blood cells were positive for HCV antibody. Only 3/38 (7.9%) patients with less than 10 U of packed red blood cells in the past were positive for HCV antibody. None of the patients who never received blood transfusion were positive for HCV antibody (0/31 or 0%). A total of seven liver biopsies were performed in patients positive for HCV antibody. Two out of seven specimens (28.57%) showed significant liver damage. One revealed cirrhosis, and the other showed chronic active hepatitis. The remainder of liver biopsies (5/7; 71.42%) showed only mild portal inflammation.
CONCLUSIONS: The prevalence of HCV antibody is directly related to the number of blood transfusions in patients with sickle cell disease. Chronic HCV infection could be a major cause of cirrhosis of the liver in these patients.
