Human herpes virus 8 (HHV-8) seems to be involved in the pathogenesis of Kaposi s sarcoma. In vitro, antiviral drugs with activity against herpes viruses also can suppress HHV-8, however, little is known about the antiviral activity against HHV-8 in vivo. In this report we describe the effects of foscarnet on HHV-8 viremia in an HIV-infected patient with disseminated Kaposi s sarcoma and a presumably HHV-8 associated hemophagocytic syndrome. HHV-8 DNA could be detected in this patient by PCR in peripheral blood mononuclear cells (PBMC), in bronchoalveolar fluid and tumor biopsies. After initiation of foscarnet because of a severe hemophagocytic syndrome HHV-8 PCR turned negative in PBMC, but stayed positive in pleural effusions and in a tumor biopsy. After termination of foscarnet therapy HHV-8 DNA in PBMC persistently reappeared. Under treatment with foscarnet the hemophagocytic syndrome dramatically improved, suggesting that HHV-8 had a pathogenetic role in this syndrome.

D012514 Sarcoma, Kaposi A multicentric, malignant neoplastic vascular proliferation characterized by the development of bluish-red cutaneous nodules, usually on the lower extremities, most often on the toes or feet, and slowly increasing in size and number and spreading to more proximal areas. The tumors have endothelium-lined channels and vascular spaces admixed with variably sized aggregates of spindle-shaped cells, and often remain confined to the skin and subcutaneous tissue, but widespread visceral involvement may occur. Kaposi's sarcoma occurs spontaneously in Jewish and Italian males in Europe and the United States. An aggressive variant in young children is endemic in some areas of Africa. A third form occurs in about 0.04% of kidney transplant patients. There is also a high incidence in AIDS patients. (From Dorland, 27th ed & Holland et al., Cancer Medicine, 3d ed, pp2105-7) HHV-8 is the suspected cause.
