Study Summary

The purpose of this study is to see how often Pneumocystis carinii pneumonia (PCP) occurs in HIV-positive patients who have stopped taking medications that help prevent PCP. The risk of developing PCP may be decreased when an HIV-positive patient's CD4 cell counts (cells of the immune system which fight infection) are more than 200 cells/mm3. This study looks at whether it is acceptable to stop PCP prevention treatment in these patients.
