Abstract:
Since the Kaposi's sarcoma-associated herpesvirus (KSHV also referred to as HHV-8, human herpesvirus-8) was discovered it has been shown that the virus is associated with all cases of Kaposi's sarcoma (KS) classical, endemic, or AIDS associated. In the numerous countries where the seroprevalence of this virus has been studied, data demonstrate that the virus is not ubiquitous in general healthy human populations as is the case with other human herpesviruses. Many seroprevalence studies to detect antibodies to HHV-8 have now been conducted using a variety of immunologic techniques. While these assays are not in total agreement and may overstate or understate the positivity of sera in the general population, they all show similar general antibody trends. For general populations the seroprevalence in sub-Saharan Africa is the highest, approximately 40% positive; in Mediterranean countries the seroprevalence is approximately 10%; whereas northern European, southeast Asian, and Caribbean countries have seroprevalence rates in the 2-4% range. In the United States, a 'mixing bowl' country the seroprevalence is in the range of 5-20%. In people with KS whether AIDS associated, classical, or endemic and other HHV-8 associated diseases such as multicentric Castleman's disease and certain body cavity lymphomas (BCL), also called primary effusion lymphoma (PEL) the seroprevalency rates are >90%. In populations with HIV-1 infection but no diagnosis of KS, the seroprevalency rates are elevated (20-50%) above those in the general population except in southeast Asia and the Caribbean where no AIDS associated KS has been reported. No correlation has been found between the presence of KSHV antibodies and other malignancies. Copyright 1999 Academic Press.
