PURPOSE: To describe our experience with discontinuation of anticytomegalovirus maintenance therapy in patients who have had immune reconstitution after initiation of highly active antiretroviral therapy. METHODS: Fifteen patients with treated cytomegalovirus retinitis, who had immune reconstitution after initiation of highly active retroviral therapy, had anticytomegalovirus maintenance therapy discontinued. Patients were followed closely for relapse of retinitis. RESULTS: Median nadir CD4+ T- cell count, before institution of highly active antiretroviral therapy, was 20 cells/μl. At the time of discontinuation of anticytomegalovirus therapy, median CD4+ T-cell count was 297 cells/μl. Patients were followed for a median of 8 months off anticytomegalovirus therapy (range, 3 to 16 months). The median CD4+ T-cell count at last follow-up was 267 cells/μl. No patient off anticytomegalovirus therapy relapsed. CONCLUSION: In selected patients with immune reconstitution after initiation of highly active antiretroviral therapy, anticytomegalovirus therapy may be safely discontinued, at least temporarily. Longer follow-up of these patients is needed to determine how long such therapy may be interrupted, and when anticytomegalovirus therapy should be reinstituted.
