The HIV Diagnosis Management of the HIV-infected patient in the primary care setting Lauren Pence, PharmD Ambulatory Care Clinical Pharmacy Specialist, Eskenazi Health Thursday, September 18, 2014 This speaker has no actual or potential conflicts of interest to disclose in relation to this presentation Identify the role of the primary care healthcare team in management of HIV patients Describe how current antiretroviral medications inhibit the mechanism of infection of the HIV retrovirus Develop a “checklist” for appropriate considerations in primary care patients with HIV Identify common adverse effects of current antiretroviral medication The HIV Diagnosis You are a successful and cheerful pharmacist in 2014 You attend a conference with a presentation on HIV infection in the primary care setting. There is a special at Jimmy John’s across the street and they are giving your favorite sandwich away for free. What do you choose to do? A SKIP IT I won’t be seeing HIV patients in my practice, anyway B SKIP IT I feel comfortable with HIV management, and Jimmy John’s is delicious C ATTEND They have free lunch at the conference, anyway • Unfortunately, your friend who told you about this Jimmy John’s giveaway was mistaken, and it turns out they gave away free sandwiches yesterday. The store is closed and you get no lunch. • You return to your ambulatory care practice after the conference with a new patient with HIV on your physicians’ schedule. You forget the names of the HIV medications, but don’t have the handout to reference that was given at the lecture. You are hungry and sad. Here’s to better luck next time… • You attend the presentation and learn a few new things about how to monitor HIV patients. • You return to your ambulatory care clinic after the conference with a new patient with HIV on one of your physicians’ schedule. You remember the adverse effects of the patients HAART regimen from the lecture, and recommend the appropriate labs. Your physician is very impressed with your HIV knowledge. Congratulations!

A PPI Initiate omeprazole 40 mg daily B H2RA Initiate ranitidine 150 mg BID C Antacid Initiate calcium carbonate Absorption of boosted atazanavir can be decreased with simultaneous administration of PPIs. Therefore, PPIs are not recommended in PI-experienced patients After prescribing your patient omeprazole 40 mg, the patient is not adequately absorbing his boosted atazanavir, leading to possible resistance. Here’s to better luck next time… Absorption of boosted atazanavir can be decreased with administration of certain acid suppressing agents, if not administered at the appropriate time. After prescribing your patient ranitidine 150 mg BID but not counseling him on the appropriate timing of the doses, the patient takes it inappropriately and is not adequately absorbing his boosted atazanavir, leading to possible resistance. Here’s to better luck next time… If patient takes calcium carbonate simultaneously with boosted atazanavir, decreased atazanavir concentrations are expected After prescribing your patient calcium carbonate but not counseling him on the appropriate timing of the doses, the patient takes it simultaneous with his HAART regimen and is not adequately absorbing his boosted atazanavir, leading to possible resistance.

Is this an appropriate contraception regimen? What would you recommend as the most appropriate regimen? A YES Condoms also reduce HIV transmission and STD risk B NO Prescribe combined oral contraceptive in addition to condoms C NO Prescribe depoprovera in addition to condoms Condoms are recommended to prevent pregnancy, but also to decrease HIV and other sexually-transmitted infections Recommendations encourage patients to use a secondary method of contraception to decrease the risk of unplanned pregnancy Your patient is not currently using effective contraception, and is currently at risk for an unplanned pregnancy while on efavirenz, which is teratogenic. Here’s to better luck next time… A secondary type of contraception is recommended in addition to condoms. Efavirenz decreases the concentrations of levornogestrel and norgestimate. You choose a combined oral contraception product that does not interact with efavirenz, and your patient is adequately protected from unplanned pregnancy while on a teratogenic medication (efavirenz) Congratulations!
