Complete histological regression of Kaposi's sarcoma following treatment with protease inhibitors despite persistence of HHV-8 in lesions.

There is no current curative treatment for HIV-related Kaposi's sarcoma. The identification of human herpesvirus-8 as a possible aetiological agent suggests potential efficacy of anti-viral agents. We report here on the complete histological remission of Kaposi's sarcoma following treatment with protease inhibitors, even in patients with limited virological response and persistence of HHV-8.
