  3. SPARTAC Trial: Short-Course ART vsNo ART in Primary HIV Infection • 372 patients identified within 6 months of infection randomized to 12 (ART12) or 48 (ART48) wks of therapy, which was then stopped, vs to no immediate ART • Effect of ART48 on time to primary endpoint increased when ART started within 12 wks of seroconversion (HR: 0.48; P = .003) • HIV-1 RNA setpoint 0.44 log10 copies/mL lower in ART48 arm vs SOC 36 wks after ART interruption • CD4+ cell count higher over longer-term follow-up with ART48 vs SOC ART48 vs SOC HR: 0.63(95% CI: 0.45-0.90; P = .01) 1.00 ART48 ART12 0.75 SOC Probability of Not Reaching Primary Endpoint 0.50 ART12 vs SOC HR: 0.93 (95% CI: 0.67-1.29; P = .67) ART 48 vs ART12 HR: 0.68 (95% CI: 0.48-0.96; P = .03) 0.25 0 0 1 2 3 4 Yrs Fidler S, et al.

  4. HPTN 052: Immediate vs Delayed ART in Serodiscordant Couples • Primary efficacy endpoint: virologically linked HIV transmission • Primary clinical endpoints: WHO stage 4 events, pulmonary TB, severe bacterial infection and/or death • Couples received intensive counseling on risk reduction and use of condoms Immediate ART Initiate ART at CD4+ cell count 350-550 cells/mm3 (n = 886 couples) HIV-infected, sexually active serodiscordant couples; CD4+ cell count of the infected partner: 350-550 cells/mm3 (N = 1763 couples) Delayed ARTInitiate ART at CD4+ cell count ≤ 250 cells/mm3* (n = 877 couples) *Based on 2 consecutive values ≤ 250 cells/mm3. DSMB recommended release of results as soon as possible following April 28, 2011, review; follow-up continues but all HIV-infected partners offered ART after release of results Cohen MS, et al.

  26. Challenges in HIV Treatment and Care in a Resource Constrained Environnement

  27. Challenges to ensure the successof ART programs in low- and middle-income countries * Increase coverage * Ensure financing sustainability * Reduce AIDS and HIV non-AIDS morbidity, and mortality * Implement 2010 WHO guidelines * Improve assessment of programs efficacy * Improve prevention, diagnosis, and management of adverse events * Improve retention * Ensure comprehensive HIV care

  28. Challenge 2:Financingsustainability 80-95% of funds are from international donors Achilles’ heel of ART programs Source Hecht R, Lancet 2010

  29. FINANCEMENTSNeeds * 15 million people on ART by 2015 * 22-24 billion/year in 2015, 8-10 millions necessary * From Roma Addis * Necessary involvment of LMIC countries to fund HIV and sustain ART and prevention programs, no more time to delay; Economiccrisis Reduction of the donorsfunds Report of 2011 GF round

  30. ART at 350 CD4 vs. 200 CD4 Where to find patients at earlier stage of HIV disease ?

  31. 8 countries:3 EasternAfrica, 3 SouthernAfrica, 1 Western Africa, 1 Central Africa 267 sites (ICAP centers) 121 404 patients Median CD4 136 cells/l Nash D, AIDS 2011

  32. ART at 350 CD4 vs. 200 CD4 • Find patients wiht higher CD4 counts • Change the paradigm • Target HIV negative patients • Increase Voluntary Counseling and Testing (VCT) • Facilitate or strenghten the link between VCT centers and ART clinics • Anticipate and face an increase in the number of patients on ART • Demonstrate cost effectiveness/acceptability to governments and donors

  33. 1.4% of adultsreceiving ART 76.5% LPV/r 45% suboptimal NRTI regimen?? Towards universal access: Scaling up priority HIV/AIDS interventions in the health sector Progress report 2010

  34. WHO/UNAIDS/UNICEF. Progress report 2011

  35. Challenges for second line • Costs • Time to switch to second line in patients failing 1st line • Effective NRTI backbone • Place of drugs already ordered or used (ABC/ddI) • Fixed Drug Combination or co-blister • Availability of ritonavir heat stable capsule • Use in TB co-infected patients • Forecasting (Renaud-Thery F, AIDS Res and Treatment 2011)

  36. Comparaison of prices for ART regimen according to line of treatment X 7 MSF, AntiretroviralTherapypricereductions, 13thedition, July 2010

  37. Long term monitoring issues We need tests for : • Metabolic syndrom… • Renal function … • Bone Mineral density … • Cardio-vascular assessment … • Malignancies diagnosis …

  38. Conclusion

  39. « A perpetual challenge willbe living up with the commitment  and courage of thosewhowentbefore- health care workers, scientists, and affectedpersons- whofaced the unknown and tookrisks. In general 30 years of AIDS confirmthatthereisindeed « more to admire in men than to despise »
