CD4 cell-monitored treatment interruption in patients with a CD4 cell count > 500 x 106 cells/l

Abstract

BACKGROUND: Little is known about CD4 cell count changes in patients with high CD4 cell counts who interrupt antiretroviral therapy, especially in those with a nadir of 250-350 x 10 cells/l. METHODS: Data derived from 139 patients from seven prospective cohorts who had > 12 months highly active antiretroviral therapy (HAART), CD4 cell count nadir of > 250 x 10 cells/l and at pre-interruption of > 500 x 10 cells/l. Endpoint was time to CD4 cell count 350 x 10 cells/l for a substantial period of time
