Abstract
Parvovirus B19 infection may cause chronic anemia in human immunodeficiency virus (HIV)-infected hosts. Small-scale studies and case reports have suggested that parvovirus B19 infection is a significant cause of anemia in HIV-infected patients. We studied single serum samples from 317 consecutive HIV-infected patients with use of parvovirus B19-specific serology and polymerase chain reaction for detection of viral DNA. Anemia was noted in 176 patients (55.5%); 126 (39.9%) had 9 CD4+ cells/L. In this study group, 191 (60.3%) of the patients were positive for parvovirus B19 IgG. Seroprevalence rates did not differ between patients with low and higher CD4+ cell counts or between anemic and nonanemic patients. Parvovirus B19 DNA was detected in none of the sera. In a control group of 226 healthy male blood donors, the seroprevalence of parvovirus B19 IgG was 68.1%; two IgG-positive sera also contained parvovirus B19 DNA. This study demonstrates that chronic parvovirus B19 infection should not be considered a frequent cause of anemia in HIV-infected individuals.
