A Study of Retrovir in the Treatment of Psoriasis in HIV-Positive Patients

Retrovir Capsules in the Treatment of Psoriasis in HIV Antibody Positive Patients: A Pilot Study

To evaluate the feasibility of Retrovir (AZT) in the treatment of psoriasis in HIV antibody positive patients. Retrovir has been shown to be effective in the treatment of AIDS. In addition, the administration of AZT appears to have induced a remission of psoriasis in one case study. In light of AZT's antiviral activity and potential effectiveness as an agent for the treatment of psoriasis, this would be the most likely treatment for HIV positive, psoriatic patients whose disease progresses quickly.

Inclusion Criteria

Study participants must have biopsy-proven psoriasis with 3 distinct psoriatic lesions. (Biopsy-proven Reiter's syndrome patients with 3 distinct cutaneous lesions may be included.) Documented HIV antibody (by federally licensed ELISA test) positive patients.

• Significant hepatic dysfunction.

Concurrent Medication:

Excluded:
