Efficacy of Elevated CD4 Counts on CMV Retinitis

Summary

Some patients with HIV/AIDS suffer from a dangerous viral infection of the retina (and other organs) called cytomegalovirus infection (CMV). The medications currently used to treat CMV all have serious side effects. AIDS patients are prone to this infection because their immune system produces a lower number of CD4+T lymphocytes, the type of blood cells that fight viral infections.

Some new HIV medications strengthen the immune system. This study will investigate the possibility that CMV patients on these HIV medications can develop immune systems strong enough to fight CMV without CMV medication. The study will enroll a maximum of 15 adult HIV/AIDS patients who have a CD4+T cell count over 150 cells/microliter and who have inactive CMV retinitis that is not immediately sight threatening. It is expected to last approximately 2 years.

Each prospective participant will have a physical examination and complete eye examination, including retina photographs, with the eye examination and retina photographs repeated 2 weeks later. If there is no evidence of active CMV retinitis, the participant will be enrolled in the study, and CMV medication will be stopped. The participant will have physical and eye examinations every 2 weeks for the first 3 months of the study, and every 3 weeks for the next 3 months. After 6 months, the frequency of the examinations will be 2-8 weeks, depending on the participant's CD4 count. After one year, a participant with a CD4 count remaining over 150 cells/microliter may return to the care of a local ophthalmologist with HIV/CMV experience, revisiting the clinical center every 6 months. The participant's CMV medication will be restarted when CMV retinitis becomes active, which will terminate participation in the study.
