A Study to Evaluate the Impact of Stopping Treatment for the Prevention of Pneumonia in HIV-Positive Patients Receiving Anti-HIV Drugs Who Have Increased CD4 Cell Counts

2014-08-27 03:59:54 | BioPortfolio

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.

Description

The risk of developing PCP may be decreased with treatment-induced recovery of CD4 counts to > 200 cells/mm3. Few data exist to confirm or negate the continued necessity of PCP prophylaxis for such patients. This study will assess the effects of discontinuing therapy.

Subjects are asked to discontinue PCP prophylaxis if antiretroviral therapy has resulted in a sustained CD4 increase greater than 200 cells/mm3 on two measurements at least 12 weeks apart. They will be evaluated for symptoms and CD4 counts every 8 weeks as well as plasma for HIV-RNA every 16 weeks for 18 months. Subjects whose CD4 count falls to less than 150 cells/mm3 or between 150 and 200 cells/mm3 will have the CD4 count re-evaluated immediately or within 4 weeks. If the second CD4 count is less than 200 cells/mm3 for either case, conventional PCP prophylaxis will be resumed and the subject will be followed on study. Subjects will be followed during study by physical exams and laboratory tests at Weeks 4, 8, and every 8 weeks thereafter.

Medical and Biotech [MESH] Definitions

A species of PNEUMOCYSTIS infecting humans and causing PNEUMOCYSTIS PNEUMONIA. It also occasionally causes extrapulmonary disease in immunocompromised patients. Its former name was Pneumocystis carinii f. sp. hominis.

The prototype species of PNEUMOCYSTIS infecting the laboratory rat, Rattus norvegicus (RATS). It was formerly called Pneumocystis carinii f. sp. carinii. Other species of Pneumocystis can also infect rats.

A pulmonary disease in humans occurring in immunodeficient or malnourished patients or infants, characterized by DYSPNEA, tachypnea, and HYPOXEMIA. Pneumocystis pneumonia is a frequently seen opportunistic infection in AIDS. It is caused by the fungus PNEUMOCYSTIS JIROVECII. The disease is also found in other MAMMALS where it is caused by related species of Pneumocystis.

Infections with species in the genus PNEUMOCYSTIS, a fungus causing interstitial plasma cell pneumonia (PNEUMONIA, PNEUMOCYSTIS) and other infections in humans and other MAMMALS. Immunocompromised patients, especially those with AIDS, are particularly susceptible to these infections. Extrapulmonary sites are rare but seen occasionally.

A genus of ascomycetous FUNGI, family Pneumocystidaceae, order Pneumocystidales. It includes various host-specific species causing PNEUMOCYSTIS PNEUMONIA in humans and other MAMMALS.
