| seroprevalence of human herpesvirus-8 in blood donors from different geographical regions of argentina, brazil, and chile. | human herpesvirus-8 (hhv-8) causes kaposi's sarcoma (ks) and lymphoproliferative disorders in both hiv-infected and uninfected patients. hhv-8 has a worldwide occurrence but infection rates vary according to a combination of geographic and behavioral risks. the main transmission route seems to be sexual, nevertheless, nasal secretions, saliva, blood, and organ graft have been proposed. hhv-8 was postulated as a new infectious agent for screening in blood donors. the aim of this study was to eval ... | 2004 | 14981770 |
| prevalence of, and risk factors for kaposi's sarcoma-associated herpesvirus infection among blood donors in brazil: a multi-center serosurvey. | kaposi's sarcoma-associated herpesvirus (kshv) is endemic in the amazon and rare in southern regions of brazil. however, geographical distribution and epidemiological correlates of infection in this large country are still poorly defined. to estimate the seroprevalence of, and risk factors for, kshv infection in brazil, a multi-center study was conducted among 3,493 first-time voluntary unpaid blood donors from salvador, sao paulo and manaus. antibodies against kshv were detected using a whole-v ... | 2008 | 18461622 |
| Non-detection of human herpesvirus 8 (HHV-8) DNA in HHV-8-seropositive blood donors from three Brazilian regions. | Human herpesvirus 8 (HHV-8), also known as Kaposi's sarcoma-associated herpesvirus (KSHV), is the etiologic agent of all forms of Kaposi's sarcoma, primary effusion lymphoma and the plasmablastic cell variant of multicentric Castleman disease. In endemic areas of sub-Saharan Africa, blood transfusions have been associated with a substantial risk of HHV-8 transmission. By contrast, several studies among healthy blood donors from North America have failed to detect HHV-8 DNA in samples of seroposi ... | 2011 | 21858163 |
