  5. Polling QuestionBaseline Survey • Please take out the Baseline Survey from your packet • Fill out the demographic information at the top of the form; then, throughout the program, as Baseline Survey questions are asked, please take a moment to select your answer to the corresponding question on this form • Your answers are important and will help us shape and improve future CME activities: • Degree:___ MD/DO ___ Nursing Professional ___ PharmD • ___ Other:_____________________________ • Specialty: ___ Internist ___ Infectious Disease Specialist ___ PCP • ___ Other: _____________________________

  6. Polling QuestionBaseline Survey Please rate your confidence in your ability to individualize antiretroviral therapy for patients newly diagnosed with HIV-1 • Not at all confident • Slightly confident • Confident • Very confident • Expert

  7. Polling QuestionBaseline Survey How often do you consider a patient’s cardiovascular comorbidities when selecting an initial antiretroviral therapy for HIV-1? • Never • Rarely • Sometimes • Most of the time • Always

  8. Polling QuestionBaseline Survey In a recent trial by HPTN 052, early initiation of ART was associated with which of the following outcomes compared to deferred initiation of therapy? • Decrease in mortality • Decreases in risk for transmission of HIV and development of AIDS-related conditions • Decrease in transmission of HIV, but no difference in AIDS-related conditions or mortality • Decreases in mortality, risk for transmission of HIV, and development of AIDS-related conditions

  9. Case • 58-year-old manwith a new HIV diagnosis. • Tested as part of an evaluation for prolonged viral syndrome, now recovered; previous negative test 8 months earlier. • PMHx: • Hypertension • Diabetes • Non-alcoholic steatohepatitis • Stage III kidney disease (eGFR 30-59) • Esophageal reflux

  10. Case • Medications: amlodipine, lisinopril, glipizide, metformin, simvastatin, pantoprazole. • Social history: Works as a medical interpreter at a local hospital; MSM, in a long-term relationship (partner also newly diagnosed HIV+); 2-3 drinks/week; no cigarettes or other drugs. • PE: BMI = 31; liver edge 2 cm below costal margin; 1+ bilateral edema.

  11. Case Labs • Glucose = 185; HgbA1c = 7.9 • Creatinine = 1.6 (eGFR = 50, calculated creatinine clearance 61) • ALT = 85, AST = 90; HBSAb positive, HCV antibody and RNA negative • Total cholesterol 230 (non-fasting) • U/A 1+ protein • HLA-B*5701: Negative • CD4 cell count = 780 (34%) • HIV RNA = 45,000 • Genotype: No resistance

  19.

  23. IAS-USA 2014 Guidelines:What to Start * ABC has been associated with increased CV risk, although data are conflicting; use with caution in patients with high CV risk. Should only be used in HLA-B*5701-negative patients. † Rilpivirine-based therapy is not recommended in patients with baseline HIV-1. € The combination of abacavir and lamivudine was less efficacious with baseline HIV-1 RNA level above 100,000 copies/mL than the combination of tenofovir and emtricitabine when combined with efavirenz or ritonavir-boosted atazanavir. GunthardHFet al JAMA. 2014;312:410-425.

  45. Summary of Results from Tx-Naïve Phase III Studies of EVG/COB/TDF/FTC • Virologic outcomes noninferior to EFV/TDF/FTC and ATV/RTV + TDF/FTC • Activity sustained in high VL stratum • 2% failed with resistance, usually to both NRTIs and EVG • Adverse events • vs EFV: fewer CNS, rash events; better lipids; more nausea • vs ATV/RTV: less jaundice • Small, rapid increase in serum creatinine related to cobicistat’s inhibition of tubular secretion of creatinine from inhibition of MATE-1 transporter
