CD4 T cell apoptosis by the intrinsic pathway represents the determinant mechanism of the unsatisfactory immune recovery and should be targeted to manage therapy for discordant patients. The predictive value of low nadir CD4 T cell count for a poor immune recovery led us to consider starting antiretroviral therapy earlier. No differences were observed among antiretrovirals in terms of immune recovery.
