The ANRS 116 SALTO trial, a prospective, open-label, multicenter trial conducted in France, enrolled 99 patients, 63 of whom were men. At 24 months, 88% of patients (95% CI, 80 ??93) did not meet study criteria to reinitiate HAART: a decrease in CD4 cell count to 300 cells/弮L or the occurrence of an AIDS-defining event. More than three quarters (77%) did not resume HAART. Statistical analysis indicated that HIV- DNA level, CD4 nadir, CD4 at HAART initiation, CDC stage, and HIV risk category were significant risk factors for HAART reinitiation.
