hepatitis C, or human immunodeficiency virus (positive HIV 1/2 antibodies). Patients
with a past or resolved HBV infection (defined as the presence of hepatitis B core
antibody [anti-HBc] and absence of HBsAg) are eligible. Patients positive for
hepatitis C (HCV) antibody are eligible only if polymerase chain reaction is negative
