title: Interferon inactivator(s) in patients with AIDS and AIDS-unrelated Kaposi's sarcoma.
abstract: Interferon inhibitory activity was found in the plasma of 11 of 14 patients with the acquired immune deficiency syndrome (AIDS). This was not seen in 75 normal persons, including six whose specimens were randomly and blindly interspersed among the patient samples. Plasma from a single patient with the AIDS prodrome (AIDS-related complex), who later demonstrated AIDS, did not contain interferon inhibitors but did contain high levels of interferon. Three patients with AIDS-unrelated Kaposi's sarcoma had neither significant levels of interferon nor interferon inhibitory activity. The existence of interferon inhibitory activity in the plasma has to be taken into account when interferon preparations are administered therapeutically.
