  2. Background • Morphologic changes (lipoatrophy and lipohypertrophy), insulin resistance, and dyslipidemia are important metabolic consequences of antiretroviral therapy in patients with HIV/AIDS • However, long-term comparative data on the metabolic effects of initiating different ART strategies in ART-naïve patients are limited

  3. Objectives • To assess long-term changes in metabolic parameters and body composition among antiretroviral-naïve patients randomized to three highly active antiretroviral therapy (ART) strategies

  4. Patient meets eligibility requirements Randomized to 3 strategy arms (1:1:1) N=1,397 PI + NRTIs N=470 NNRTI + NRTIsN=463 PI + NNRTI + NRTI(s) N=464 PI Strategy N=141 in Metabolic substudy NNRTI StrategyN=141in Metabolic substudy PI + NNRTI Strategy N=140 in Metabolic substudy C•P•C•R•A

  8. Change in LDL Cholesterol* * If triglycerides ≥ 400, direct LDL, otherwise calculated LDL

  9. Change in HDL Cholesterol

  10. Change in Triglycerides

  11. Change in Insulin

  12. Conclusions - I • PI+NNRTI strategy associated with a greater increase in LDL-C and triglycerides compared to the PI or NNRTI strategies; no significant differences noted between PI and NNRTI strategies • LDL-C levels increased primarily within the first few months after initiation of ART, followed by a decline during the remainder of follow-up

  13. Conclusions - II • Unlike LDL-C, triglyceride levels did not decline with continued therapy • Significantly greater increases in mean HDL-C seen with the NNRTI strategy compared to the PI strategy • PI+NNRTI strategy should be avoided unless no other options are available

  14. Conclusions - III • Increases in insulin and glucose were noted during follow-up, with no differences by ART strategy • Increases in insulin and glucose were gradual and continued throughout follow-up, unlike the pattern of changes noted with the lipids • Findings support the need for ongoing monitoring of glucose levels as well as for the development of diabetes, irrespective of ART regimen used
