Abstract
Intensive plasma exchange was performed in seven male homosexual patients with AIDS and Kaposi's sarcoma. Serial 1.2 plasma volume exchange procedures were performed three times a week for six weeks. In five of the patients, plasma replacement included gamma globulin in the form of plasma (two patients), or an IV IgG preparation (three patients). No changes in the mean number of helper-inducer or suppressor-cytotoxic cells were noted during the treatment period or the weeks following completion of the last procedure. The mean mitogenic response of the patients' lymphocytes to PHA increased by 32.4% during the course of the plasmapheresis procedures (p <.05), but returned to baseline over the eight weeks following treatment. Mitogenic responsiveness to PWM did not significantly increase during the course of treatment. No regression of Kaposi's sarcoma lesions was found in any of the patients treated.
