Youth and HIV PEP, Pr. EP, Tas. P Peter L. Havens, MD Winter 2019
Patient Background • • • 16 y. o. female History of depression Prior suicide attempts Diabetes mellitus type 2 Mild asthma Lives in a group home
• • • Medications Valproate (recently added to psych meds) Ziprasidone Mirtazapine Clonidine Prazosin (for PTSD) Benztropine (for drug-induced extrapyramidal symptoms including eyes tonically looking upward Depo-provera Metformin Nicotine patch
Symptoms began Sept 2 • • Drowsiness: falling asleep frequently Dizzy-blurry vision-headache Sore throat—so severe it limited eating Generalized body aches Vomiting-rare Diarrhea—infrequent No fevers No rash
ED Hospital Admission Sept 9 (Day 7) Lethargy and Weakness • Non-focal exam. No fever • Excessively sleepy/lethargic. • Diagnosis: Altered mental status from drug use and diarrhea with dehydration • Treatment: IV fluids [and no more drugs except those prescribed] • Check some labs
Hospital Labs 9/9 (Illness Day 7) • WBC=2. 9: PMN 43%; Lymphs 44%; reactive lymphs 4% • Hemoglobin 11. 2 • Platelets 43, 000 • ALT=55; albumin=3. 0 • CT head, CXR, ECG all normal • Drug screen positive cannabinoids and cocaine
Diagnostic considerations • Valproate-induced marrow suppression? – stopped the valproate • Viral infection? – EBV serology: prior infection • Urine chlamydia positive so consider STI even though in group home
Further Laboratory Evaluation 9/11= Illness Day 9 • 9/11 --HIV DNA PCR was positive (state lab) • 9/11 --HIV RNA PCR >10, 000 copies/m. L (Focus--Roche) • 9/11 --HIV Ag/Ab screen negative (Determine --CHW) • 9/14 --HIV Ag/Ab reactive (WDL) but HIV-1 Ab differentiation assay indeterminate. HIV-2 Ab differentiation assay negative • 9/14 --HIV RNA PCR 1, 664, 578 (WDL-Roche) • 9/14 -CBC normal; ALT ↑ 162;
More Labs • 9/14 --CD 4 cell count 420 (29%); CD 8=594 (normal 230 -1090); CD 4/CD 8 ratio = 0. 71 (normal 0. 66 -3. 52) • 9/14— – HIV genotype: no drug resistance. – HLA B 57*01 negative
Diagnosis • Acute symptomatic HIV Infection Braun DL. CID 2015; 61: 1013. Frequency and Spectrum of Unexpected Clinical Manifestations of Primary HIV-1 Infection
• • • Diagnosis = Symptomatic HIV Infection Initiate antiretroviral therapy Anticipate lifelong treatment (70 years) Combination antiretroviral therapy (c. ART) 3 drugs (one or two pills, once daily): – 2 nucleoside reverse transcriptase inhibitors (NRTI) plus • protease inhibitor (PI) or • non-nucleoside reverse transcriptase inhibitor (NNRTI) or • integrase inhibitor (INSTI) Balance benefit and toxicity
Treatment: One Pill Once Daily Fixed Dose Combination Tablets FDC by FDC Components class Brand name Atripla Complera Odefsey Symfli LO Biktarvy Triumeq Genvoya Minimum body weight (kg) EFV 600 mg + FTC 200 mg + TDF 300 mg 40 FTC 200 mg + RPV 25 mg + TDF 300 mg 35 FTC 200 mg + RPV 25 mg + TAF 25 mg 35 EFV 400 mg + 3 TC 300 mg + TDF 300 mg 35 BTG 50 mg+ FTC 200 mg +TAF 10 mg 25 ABC 600 mg + DTG 50 mg + 3 TC 300 mg 25 EVG 150 mg + cobi 150 mg + FTC 200 mg + TAF 10 mg 25 Stribild EVG 150 mg + cobi 150 mg + FTC 200 mg + TDF 10 mg 35
• • What I say to an adolescent at our first visit You are not going to die from this. Life expectancy is good for those with HIV. – A person with HIV who takes one pill once daily and has viral load suppression Lives longer than a person who – Is Overweight / does not exercise /smokes Try to keep HIV in perspective in your life – Taking your medicine takes less time than brushing your teeth Undetectable = Untransmittable U=U
Objectives • • • How to call the HIV program How to test Whom to test Treatment of persons exposed to HIV (PEP) Treatment of those who test negative (Pr. EP) Treatment of those who test positive (Tas. P)
CHW HIV Program: Always on Call
HIV Testing at CHW
CDC HIV Testing Recommendations-June, 2014 Day after HIV Acquisition HIV Test Then what happens Day 0 HIV Infection Day 10 HIV RNA or DNA PCR (NAAT test) Day 22 Peaks about day 30 after infection. Plateaus around day 40. The antigen marker, p 24 peaks about 4 th generation immunoassay 30 days after infection, rapidly (HIV antibody/antigen test) decreases & may become undetectable ** Detects antigen (p 24) about 45 days after infection The test marker, Ig. M, peaks at about 35 3 rd generation immunoassay days then decreases until about 38 days (HIV antibody screen) when Ig. G antibodies are detectable **Detects Ig. M & Ig. G using a 2 nd generation test Day 38 2 nd generation immunoassay (HIV antibody screen and antibody differentiation tests such as the multispot) **Detects Ig. G Day 15 The test marker, Ig. G continues to increase until they are detectable by first generation tests and the western blot by day 45 -50 Bernard Branson et al (CDC).

CDC HIV Testing Recommendations-June, 2014 Screen positive Second test Positive or Negative or Indeterminate Perform HIV NAT (HIV DNA or RNA assay) Bernard Branson et al (CDC). Laboratory testing for HIV Infection: Updated Recommendations June 27, 2014. http: //stacks. cdc. gov/view/cdc/23447
HIV NAT • • “HIV 1 RNA Quant PCR” Viral load Plasma viral load HIV RNA Measures amount of virus in plasma Positive if untreated Goal of therapy is undetectable plasma viral load Most readily available and rapid turnaround • • • “HIV DNA PCR” Measures presence of cellassociated proviral DNA Positive if untreated Positive if plasma viral load undetectable Not readily available Slower to result
Considerations • Mono-like illness in the appropriate setting: think of HIV • Low platelets suggest pathology • HIV RNA may be positive when antibody is still negative – If you are really considering HIV send it to WDL for a 24 hour result • Acute HIV can present as fever, rash, adenopathy, throat pain (FRAT) or with primary neurologic syndromes
Who to test? • Depends on the epidemiology of HIV in your location
Availability of HIV testing should be discussed with all adolescents, and should be encouraged with consent for those who are sexually active or substance users. Pediatrics 2001; 107: 188

HIV in the World: Selected Numbers, 2017 • Every week, 7000 young women aged 15– 24 years become infected with HIV. • In sub-Saharan Africa, three in four new infections in youth aged 15– 19 years are in girls. • Young women aged 15– 24 years are twice as likely to be living with HIV as men http: //www. unaids. org/sites/default/files/media_asset/UNAIDS_Fact.

Ways to prevent HIV • • • Abstain from sex or injection drugs Always use a condom or clean works Post-exposure prophylaxis (PEP) Treatment as prevention (Tas. P) Pre-exposure prophylaxis (Pr. EP)
Post-Exposure Prophylaxis (PEP) is Routine after Sexual Assault Most PEP only requires a single dose Single Dose Only • • • Gonorrhea Chlamydia Trichomonas [Hepatitis B] [Contraception] Multiple Doses / 28 Days • HIV

Probability of acquiring HIV from an HIV-infected Source Risk per Act Blood transfusion per 10, 000 percent 9250 92. 5% No maternal ART (maternal viral load ≈15, 000 copies/m. L) 8. 5% Maternal c.

International AIDS Society-USA Panel Recommendations on Pr. EP 2014: no recommendation 2016: Daily TDF/FTC is recommended 2018: Daily TDF/FTC is recommended 1 -week lead-in to ensure adequate tissue levels Continue TDF/FTC 1 week after last exposure Pericoital TDF/FTC may be considered as alternative =on-demand, event-driven, or “ 2 -1 -1” for MSM with infrequent sexual exposure. Double dose TDF/FTC 2 -24 hr before exposure Single dose at 24 and 48 hours after exposure Saag MS. JAMA July 24, 2018 doi: 10. 1001/jama. 2018. 8431
International AIDS Society-USA Panel Recommendations on Pr. EP • HIV rapid Ag/Ab assay at start • HIV RNA if acute infection suspected • Creatinine at start and every 6 months • HIV rapid Ag/Ab and STI testing every 3 months • HCV antibody annually • Visits every 1 to 3 months • Do not prescribe more Pr. EP without HIV testing Saag MS. JAMA July 24, 2018 doi: 10. 1001/jama. 2018. 8431
Summary-1 • Recommend condoms • Test and treat – negative→Pr. EP – positive→c. ART=Tas. P • Adherence is difficult • Recommend condoms
Summary-2 • We have the tools to end the epidemic. • Why does the epidemic persist?

Types of Advice about Drinking • Abstinence – Don’t Drink • Abstinence plus harm reduction – Don’t drink, but – If you do drink, don’t drive. • If you do drink, don’t have sex –You make bad choices when you cannot think straight
Types of Advice about Sex • Abstinence – Don’t have sex until you are married • Abstinence plus harm reduction – Don’t have sex until you are married, but – If you do have sex • USE A CONDOM
Condoms cause sex Like umbrellas cause rain.

Risk of HIV Acquisition after Sexual Exposure is Reduced by Medications • Risk of HIV acquisition after a single sexual exposure is 0. 04% to 1. 38% • Antiretrovirals “reduce the risk for acquiring HIV infection after … exposure” (CDC) – Start within 72 hours – Continue for 28 days – Take all the pills
