2 Condomless Sex: Was the Swiss statement correct in 2008? Renslow Sherer University of Chicago

3 Disclosures and Objectives Disclosures Advisory Board Yes Gilead Sciences A PLWHIV on ART w/ VL < 50, as per the Swiss Statement, is NOT a public health threat.but that does not finish the discussion on how a primary clinician should talk to HIV+ and HIV at-risk persons about condom-less sex. 2 key issues: Objectives At the end of the session, the participant will be able to: 1. cite current evidence on the efficacy and effectiveness of ART as prevention; 2. review current evidence on the efficacy and effectiveness of preexposure prophylaxis (PrEP); 3. Describe the clinician's role in counseling HIV+ and HIV at-risk patients for sexual health, condoms, and condom-less sex

4 Efficacy vs Effectiveness the extent to which an intervention causes its intended effect under ideal circumstances, such as in a randomized clinical trial, the extent to which an intervention achieves its intended effect in the usual clinical setting Efficacy Clinical trial Controlled setting Limited variation Narrow intervention Designed to define degree of biologic effect of intervention Effectiveness Observational study Real world setting Broad variation Uncontrolled variables Designed to assess success of intervention in real world settings

5 Who is transmitting HIV in the US? Purpose: Estimate rate and number of HIV transmissions in US in 2009 Method: Mathematical modeling using data from National HIV Surveillance System, National HIV Behavioral Surveillance System, and Medical Monitoring Project Results: HIV+ but undiagnosed (18.1% of total HIV+ pop.) caused 30.2% HIV+ but not retained in care (45.2% of HIV+) caused 61.3% of estimated 45,000 HIV transmissions in TOTAL 91.5% Conclusion: Improvements in HIV diagnosis and retention in care, as well as reductions in sexual and drug use behavior, primarily for persons undiagnosed and not receiving ART, would substantially affect HIV transmission in the US JAMA Intern Med. 2015;175(4): doi: /jamainternmed Published online February 23, 2015.

24 Condom Myths #1 & 2 & 3 1. Condoms don t work CDC: 90+% efficacy Record of high effectiveness 2. No one uses condoms A LOT of people at HIV Open risk carefully, use condoms, no sharps often FACT: most don t use condoms all the time When used, they work so Care w/ still animal useful skins 3. Advising pts to use condoms doesn t work LIMITS TO CONDOM EFFICACY Requires agreement of wearer Re-use, over-sized Use w/ fat-soluble lube Use old, opened, dry Care w/ non-us brands Latex allergy alternatives Not effective vs HPV Brief counseling works to reduces unsafe sex

27 Why PrEP Alone is Not Enough PrEP alone does not reduce risk of STIs, pregnancy, harmful consequences of IDU For HIV Prevention, combining methods improves protection When HIV drug doses are missed or unavailable When medication alone does not completely block HIV transmission The US will become a place where new HIV infections are rare. US Nat l HIV/AIDS Strategy Dawn K Smith, CDC 2014

28 HIV Primary Caregivers: Recommendations re: Condom-less Sex 1. Promote, encourage sex, intimacy, safe touch - Screen for, recognize, address unsafe, coerced sex 2. Promote & encourage condom use; give condoms - Counter negative image, pessimism - Many people use condoms, often

29 HIV Primary Caregivers: Recommendations re: Condom-less Sex 3. Expand testing; engage & retain; ART for all Most HIV transmitted by recent Infx (1/3) or known HIV+ out of care (2/3) 4. Advise Both And : TasP/PrEP/PEP and condoms - Recommend careful candidates for long term condom-less sex and short term condom free moments - Review TasP & PrEP & condom evidence w/ pts - Follow CDC & USPHS PrEP eligibility guidelines - BROAD & generous interpretation! Streamline PrEP Access!

30 Thank You

31 3 Questions for Shannon When would you estimate that the US will achieve targets (like NY, SF)? 2 years? 5 years? More? At that time, would you recommend condom-less sex with anyone known to be HIV+? Did PEPFAR waste US taxpayer $$$ by providing 770 million condoms worldwide in 2012? How should we describe the risk of PrEP failure to our pts? USAID. hiv-and-aids/technical-areas/addressing-condom-supply-and-demand-pepfar
