Foscarnet for suppression of human immunodeficiency virus replication.
The effect of foscarnet against human immunodeficiency virus (HIV) was evaluated in nine HIV-infected individuals; six completed 28 days of induction therapy. The overall mean increase in CD4+ lymphocytes was 64 cells per mm3. The mean decline in the HIV antigen concentration was 108 pg/ml (P = 0.03), and suppression was related to systemic foscarnet exposure by a maximum-effect pharmacodynamic model.
