  1. Long Term Management of HIV Infection in Aging Adults: Current Challenges, Future Strategies Andrew Zolopa, MD Stanford University

  2. Aging of HIV Population: San Francisco • Population-based HIV registry from 2006-2010 • Registry increased from 9,001 to 9,673 mostly due to decline in deaths • Those older than 50 now 53% of population, up from 41% in 2006 --fastest growing subset of patients Age Trends of Persons Living with HIV/AIDS in San Francisco Adapted from Scheer S, et al. 6th IAS; Rome, Italy; July 17-20, 2011. Abst. TUPE131.

  3. Late HAART Era Patients Still Have a 10yShorterLife Expectancy than HIV- Controls Survival from Age 25 YearsN= 3,990 1 0.75 Population controls Probability of Survival 0.5 Late HAART (2000–2005) 0.25 Early HAART (1997–1999) Pre-HAART (1995–1996) 0 25 30 35 40 45 50 55 60 65 70 Age, years Adapted from Lohse N, et al. Ann Intern Med 2007;146:87–95 (See Also: ART-CC, Lancet, 2008; Lewden, JAIDS, 2007)

  4. Changing Patterns of the Causes of Death in a Swiss Cohort (SHCS) • SHCS is a prospective observational cohort • Characteristics of participants that died from 2005-2009 • 459 deaths/9,053 participants (5.1%) Causes of Death in Participants in the Swiss HIV Cohort Study in 3 Different Time Periods, and in the Swiss Population in 2007 Years of Death of HIV+ Persons Versus Swiss Population Adapted from Ruppik M, et al. 18th CROI; Boston, MA; February 27-March 2, 2011. Abst. 789.

  5. Accelerated or Premature Aging in HIV? • Increased Frailty • CVD Increased • Cancer • Neurocognitive Impairment • Osteoporosis • End Organ Dz • Potential Causes • Drug Toxicities • Residual HIV • Co-infections • Inflammation

  6. Many morbidities associated with aging also appear to be increased in treated HIV disease Bone fractures / osteoporosis [5,6] Cardiovascular disease [1-3] Cancer (non-AIDS) [4] Liver disease [7] Renal disease [8] Cognitive decline [9] Frailty [10] Non-AIDS infections [11] 1.

  12. Prevalence of Lipodystrophy in Current ART Era • Cross-sectional study of HIV patients at Australian clinic, comparing 1998 to 2010 • Definition of lipodystrophy (LD) from original case definition • Results: • Participants older, healthier from HIV and CV risk factor perspective • Prevalence of study-defined LD has declined from 69 to 58% • In multivariate analysis, use of tenofovir or abacavir associated with significantly lower risk • Conclusion: Although prevalence of LD has declined, it remains relatively common – especially in long-term survivors Adapted from Price J, et al. 6th IAS; Rome, Italy; July 17-20, 2011. Abst. MOPE264.

  15. Strategies For Long-term ART • Preferred ART regimens currently focus on: • effectiveness of viral suppression • relatively short-term safety Are preferred ART regimens the same for long-term treatment (i.e. decades)? • Long-term ART goal: reducing toxicity • Fewer drugs • Use ART with “high genetic barrier to resistance” • Compartment penetration?
