A 29-year-old man goes to the emergency department (ED) to request post-exposure prophylaxis (PEP) to prevent HIV infection. He has just returned from a week-long vacation, during which he had unprotected oral and receptive anal intercourse with several men whose HIV status he does not know. His last HIV test was 6 months prior to this ED visit, and the result was negative. He reports no medical problems and is not taking any medications. He receives a 28-day course of tenofovir/FTC + lopinavir/ritonavir PEP.
Four days later, the patient has a follow-up visit with his primary care provider (PCP), who is aware that he has received at least three similar courses of PEP during the previous 4 years. His HIV antibody test has again returned negative. He says he is aware of when he is going to put himself at high risk for HIV infection (usually during vacations and particular weekends) and would like a supply of tenofovir/FTC to take during these periods; however, he does not want to take the drugs continuously.
If you were the PCP, what additional history would you obtain? Would you try to change the patient's high-risk behavior? If so, what specifically would you say to him? Would you recommend tenofovir/FTC pre-exposure prophylaxis (PrEP) for him? If so, would it be continuous or intermittent? How frequently would you monitor for HIV, other sexually transmitted infections, and tenofovir/FTC toxicity? If you would not prescribe PrEP, what is your reasoning?
