When to Start ART
Risk of progression to AIDS or death in relation to CD4 cell levels in patients with sustained viral response to ART: COHERE cohort Results - event rates per 1000 years suppressed Most recent CD4 cell count (cells/µL) First new AIDS event or death from any cause (no. of events) Death from any cause (no. of events) <5094.9(54)64.8(38) 50-< (489)20.0(325) 200-< (548)6.9(318) 350-<5007.9(487)3.8(240) (679)2.4(315) Similar results in an analysis of 27,108 patients in 4 M.S.F. programs in Africa- Patients who achieved a CD4 of had 1.69 AHR for mortality compared to those who achieved CD4 >500 WELB05 Heiner; TUBDP0106 Maman
