title: Antibody patterns to herpesviruses in kaposi's sarcoma: serological association of european kaposi's sarcoma with cytomegalovirus.
abstract: Sera from patients with Kaposi's sarcoma (KS) were examined for antibody titres to cytomegalovirus (CMV), Epstein-Barr virus (EBV) and herpes simplex virus (HSV) types 1 and 2 by four techniques: indirect haemagglutination (IHA), complement fixation (CF), virus neutralization (NT) and indirect immunofluorescence (IF). The patients were classified, according to the stage of disease, as progressive and regressive. Control sera were obtained from healthy adults, matched for age, sex, race, socioeconomic status and geographic location, as well as from patients with melanoma, some of whom were receiving chemotherapy similar to that given to the KS patients. All KS sera contained CMV-neutralizing antibodies. Seventy-five percent of the European KS patients, mainly regressors, showed elevated anti-CMV titres by IHA with a significant increase in the geometric mean over the corresponding healthy adult group and the melanoma group. An overrepresentation of high anti-CMV titres, although less marked, was found by CF. There was no significant association with antibodies to EBV, HSV-1 and HSV-2 related antigens. By contrast, the African KS patients, mainly progressors, did not show a serologic association with CMV or with EBV and HSV-1 and 2. The implication of these results is discussed.
