Abstract

To examine whether the prolonged survival seen in patients treated with foscarnet compared with those treated with ganciclovir was due to a direct effect on human immunodeficiency virus (HIV) replication, HIV p24 antigen was measured. Of 71 receiving foscarnet, 54% were p24 antigenpositive at enrollment (vs. 44% of 79 receiving ganciclovir). By immune complex-dissociated (ICD) p24 antigen analysis, 87% and 78%, respectively, were positive. After 1 month of treatment, there was a significant decline in standard (mean decline, 10.1 pglmL) and ICD (mean, 39.6 pg/mL) p24 antigen in both groups (P =.0001). Mortality was greater in those who were ICD p24 antigenpositive than in those -negative at baseline (P =.03) and in subjects with an increase in ICD p24 antigen than in those with a decline (P =.09). Thus, each drug had a suppressive effect on circulating p24 antigen, which was predictive of improved survival. The inhibitory effect on CMV replication may have a beneficial effect on limiting HIV replication.
