Learning Objectives AT THE END OF THIS SESSION, THE ATTENDEE WILL BE ABLE TO: Explain HIV and its treatment to patientsTake a culturally competent sexual history/risk assessmentManage PEP for a variety of patientsManage PrEP for a variety of patientsExplain the importance of PEP/PrEP adherence to patientsDescribe PEP/PrEP funding and financial assistance5

SB 159 (Weiner): HIV Prevention SB 159 authored by Sen. Weiner was signed into law on 10/7/19. CSHP was one of multiple co-sponsors of SB 159The law amended the Business and Professions Code to allowpharmacists to “furnish” PEP and PrEP only after the CA Board ofPharmacy developed “emergency” regulations setting forth thetraining requirements for pharmacists to “furnish”. Effective 4/30/20 - Title 16, CA Code of Regulations, Section 1747 wasadded setting forth the training requirements for pharmacists tofurnish PEP and PrEP.Participants must pass quiz with 70% and maintain record of trainingfor 4 yrs. Senate Bill No. 159, CHAPTER 532: An act to amend Section 4052 of, and to add Sections 4052.02 and4052.03 to, the Business and Professions Code, to add Section 1342.74 to the Health and Safety Code,to add Section 10123.1933 to the Insurance Code, and to amend Section 14132.968 of the Welfare andInstitutions Code, relating to HIV prevention. Title 16 CCR Section 1747:https://pharmacy.ca.gov/laws regs/approved regs.shtml6

SB 159 (Weiner): HIV Prevention A pharmacist must complete training either approved by the CA Board ofPharmacy or is provided by a provider accredited by an approvedaccreditation agency. CSHP is an ACPE accredited provider and this training qualifies a pharmacist tofurnish PEP and PrEP upon successful completion.SB 159 provides authority for a pharmacist to determine if patients meetclinical criteria for PEP or PrEP. Allows them to; furnish 30 or 60 days of PrEP once every 2 years; orfurnish 28 days of PEP; andThey must inform the patients primary care provider or provide the patient with asimilar report that would have gone to their provider.7

HIV Testing22

HIV TestingThree methods to test for HIV Nucleic Acid Test (HIV Viral Load) Provides an approximate count of the virus per millimeter of blood Minimum level of detection 20copies/mL Can be in the millions of copies/mL Very costly, not commonly performed for routine screening purposes Typically reserved for suspected acute retroviral syndrome (as part of thecare of a prescriber), or as part of the routine care of someone known to beHIV 23https://www.cdc.gov/hiv/basics/testing.html

HIV TestingThree methods to test for HIV Antigen/Antibody test Looks for antigens (sections of viral protein) and antibodies to the virus Common as a confirmatory test for HIV Commonly requires a venous blood draw and a “send-out” lab analysis Results take a few days Not practical for pharmacy and many clinic practices Also available as a rapid test24https://www.cdc.gov/hiv/basics/testing.html

HIV TestingThree methods to test for HIV Antigen/Antibody RAPID test Looks for antigens (sections of viral protein) and antibodies to the virus Finger-prick blood test Results available in 30 ml

HIV TestingThree methods to test for HIV Oral Antibody test Looks for antibodies to the virus that are expressed in saliva Oral swab test Results available in 20-40 minutes Most common for point of care and rapid testing locations Pharmacies High-volume public clinics HIV/STI testing centers (stationary and 26

HIV TestingInterpretation of tests NAT (HIV Viral Load) and Antigen tests If positive – patient is infected If negative – interpretation depends on last high-risk exposure 1 month – most likely negative 1 month – probably not infected, but retest after 1-3 months to ml

HIV TestingInterpretation of tests Antibody tests If positive – patient is infected If negative – interpretation depends on last high-risk exposure 6 months prior – most likely negative 6 month – indeterminate, retest after 3 & 6 months It takes time for the body to develop antibodies Patient counseling regarding sexual history is important in interpretingHIV antibody tests28https://www.cdc.gov/hiv/basics/testing.html

HIV TestingOral Antibody test Oral antibody tests Need a CLIA waiver Use universal precautions (wear gloves, maybe mask, clean afterwards withdisinfectant) even though low risk Swab testing pad between cheek and gum, rub to moisten Place testing pad in buffer Interpret l

Counseling patients onSTIs and Sexual HistoryChristina M. Madison, PharmD, FCCP, AAHIVP35

Taking A Sexual History More than one million people who are at riskfor HIV in the United States could benefit frompre-exposure prophylaxis (PrEP) medications Only a fraction receive HIV preventionservices Taking a sexual history is an essential part ofthe HIV prevention assessment In a survey of 500 men and women 25 andolder 85% of respondents expressed an interest in talkingto their providers about sexual concerns Although 71% thought their provider would likelydismiss their concerns36National LGBT Health Education Center and National Association of Community Health Centers.

JAMA. 1999;281:2173-4.

Taking A Sexual History Assessing Risk of Sexual Transmission of HIV Assess all sexually active patients for diagnoses of bacterial SexuallyTransmitted Infections (STIs) ChlamydiaGonorrheaSyphilis Routine testing is recommended using 3 site STI testing (including oralpharyngeal and rectal samples) Assess for STIs every 3 months and Test for STIs every 6 months Epidemiologic context of reported sexual practices should be considered Consider the likelihood a sexual partner has HIV infection (geographic location) If sexual partner is HIV positive, are they receiving ART? Are they adherent? Are they your only sex partner?37CDC PrEP Guidelines. 2017

Taking A Sexual History You will be taking histories from diverse patients fromdifferent racial, ethnic, and socioeconomic background Assess all patients for alcohol abuse, especially beforesexual activity, and use of illicit non-injection drugs Refer persons reporting substance abuse to appropriatetreatment or harm-reduction services Consideration should be made for the needs of theLGBTQ community Increased risk for HIV and sexually transmitted infectionsare two of many health disparities that disproportionatelyimpact this communityEspecially women of trans experience and in particulartrans women of color38National LGBT Health Education Center and National Association of Community Health Centers.

Taking A Sexual History Taking a culturally competent sexualhistory is an essential component of theHIV prevention assessment Knowing the sexual practices and partnersof your patient helps to determine risk andallows you the provider to give effectiveharm reduction strategies Making your patient feel as comfortable aspossible is key to allowing them to disclosesensitivity information confidentially in ajudgement free space39National LGBT Health Education Center and National Association of Community Health Centers.

Transitioning from nPEP to PrEP Many individuals who present for nPEP may be excellentcandidates for PrEP, especially if they have ongoing activitiesassociated with increased risk for HIV acquisition Individuals who have completed the 28-day course of nPEPshould be evaluated for transitioning to PrEP if: They have repeatedly sought nPEP They have frequent, recurrent exposures to HIV that would requiresequential or near-continuous courses of nPEP Documentation of HIV-negative status should be obtained beforeadministering PrEP (preferably several days prior to completingthe nPEP course) Transition from nPEP to PrEP should be done immediately65CDC: US DHHS; 2016.
