5 Prognosis of late presenters Adapted from Sterne et al. CROI 2009, Abstract 525 and presentation Based on 24,444 patients from 15 cohort studies 808 deaths and 2366 events in 81,071 person-years of follow-up 0 – – – Probability of death Years since start of HAART 251 – – – 550 Years since start of cART Probability of AIDS or death

CROI Abstract 172.

14 MONOI: 48 Wk Outcomes With DRV/RTV Monotherapy vs Triple Therapy DRV/RTV monotherapy met criteria for noninferior virologic efficacy vs DRV/RTV + 2 NRTIs at Wk 48 in PP analysis, but not in ITT-E analysis –PP population = all pts from ITT population except pts who d/c tx without virologic failure or SAE (n = 10) or pts withdrawn without virologic failure or SAE (n = 6) Virologic failure in 3 pts (2.7%) on monotherapy vs 0 on standard therapy –Low DRV drug levels noted in 1 pt –No DRV RAMs in any pt with virologic failure –All 3 pts regained HIV-1 RNA < 50 c/mL on reintroduction of 2 NRTIs Virologic Response at Wk 48, %* DRV/ RTV + 2 NRTIs ΔLower Limit of 90% CI PP analysis (n = 204) ITT-E analysis (n = 225) Viremia detected in CSF in 2 of 3 pts with serious CNS disorders on monotherapy arm –Each pt had HIV-1 RNA < 200 c/mL in CSF following reintroduction of NRTIs Katlama C, et al. IAS Abstract WELBB102. Virologic failure defined as consecutive HIV-1 RNA > 400 c/mL or treatment modification or discontinuation

15 CONCLUSIONI La sopravvivenza del paziente libero da malattia deve essere lobiettivo della TARV. Il successo virologico costituisce un fattore essenziale per la prognosi a lungo termine. La prescrizione di un regime terapeutico deve tener conto anche della penetrazione nei diversi comparti.
