19 What Should I Know About HIV? 1. Relevance 2. Risk Behaviors 3. Testing 4. Medications

20 How is This Even Relevant to Me? Whether you realize it or not, HIV is here in SD Some of your patients are involved in high-risk behaviors Patients you are seeing may not mention their HIV If you don t ask, they won t tell

21 HIV: A Quick Review of the Basics The current HIV paradigm: just another chronic disease Essentially no impact on life expectancy in a significant subset of patients HIV transmission is behavior-based Tremendous progress has been made in HIV treatment, but neither a cure or a vaccine is practical Patients with HIV are just like you and me

22 HIV High-Risk Behaviors Engaging in anal, oral or vaginal sex with MSM, multiple or anonymous partners Injecting drugs with a shared needle Being diagnosed with an STD Exchanging sex for drugs or money Having rec d blood products 78 to 85 in US

23 Who Should Be Tested for HIV? All pregnant women Anyone diagnosed with any STD Everyone age (2006 CDC recommendation for opt-out testing ) At least one time and more often based on risk Up to every 3 months based on ongoing risk Understand the possibility of false positives

24 Opt-Out Testing for HIV

25 Available HIV tests Enzyme Immunoassay (EIA) Detects HIV Antibody Rapid EIA Blood Urine Saliva HIV-1 Multispot New confirmatory test Western Blot Old confirmatory test HIV-1 RNA (Quantitative) use only when acute retroviral syndrome is suspected 4 th Generation combined Ab/Ag test

26 HIV Testing at Avera and Sanford Generation 4 HIV: HIV 1 and 2 antibody PLUS a p24 antigen Turnaround time: Within 1 hour Confirmatory test still required

27 HIV Testing in Pregnancy All women should be tested at 1 st visit Higher risk of false positive EIA s in pregnancy Repeat testing in 3 rd trimester for women at increased risk of HIV: HIV prevalence in pregnant women is > 1 per 1,000 Incarcerated women Jurisdictions with elevated HIV incidence Individuals (OR THEIR PARTNERS) involved in highrisk behaviors

28 Anti-Retroviral Medication Issues Take all or take none (suboptimal adherence leads to development of resistance) Potentially-serious adverse events Marrow suppression: zidovudine Pancreatitis: didanosine, stavudine and others Hepatotoxicity: multiple, esp. nevirapine and PI s CNS side effects: efavirenz Hyperglycemia and Hyperlipidemia: PI s Bone and renal toxicity: Tenofovir

29 What do I need to know about HAART? (Highly Active Anti-Retroviral Therapy) DRUG INTERACTIONS DRUG INTERACTIONS DRUG INTERACTIONS Be aware of side effects

30 HIV Medication Timeline 1987 Zidovudine (AZT/Retrovir) Didanosine (DdI or Videx) 1992 Zalcitabine (DdC or Hivid) Stavudine (D4T or Zerit) 1995 Lamivudine (3TC or Epivir), Saquinavir (Invirase, Fortovase) 1996 Ritonavir (Norvir), Indinavir (Crixivan), Nevirapine (Viramune)

31 HIV Medication Timeline 1997 Nelfinavir (Viracept), Delavirdine (Rescriptor) 1998 Efavirenz (Sustiva), Abacavir (Ziagen) 1999 Amprenavir (Agenerase) 2000 Lopinavir/ Ritonavir (Kaletra) 2001 Tenofovir (Viread) 2003 Emtricitabine (Emtriva), Fosamprenavir (Lexiva), Enfuvertide (Fuzeon) Tipranavir (Aptivus) 2006 Darunavir (Prezista), Efavirenz/emtracitabine/tenofovir (Atripla)

32 HIV Medication Timeline 2007 Maraviroc (Selzentry), Raltegravir (Isentress) Etravirine (Intelence) Rilpivirine (Edurant), Emtricitabine/rilpivirine/tenofovir (Complera) Elvitegravir/cobicistat/emtricitabine/ tenofovir disproxil (Stribild) Dolutegravir (Tivicay)

33 HIV Medication Timeline Dolutegravir/abacavir/lamivudine (Triumeq), Elvitegravir (Vitekta), Cobicistat (Tybost) Darunavir/cobicistat (Prezcobix), Atazanavir/cobicistat (Evotaz), Elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (Genvoya)

35 Common Lab Abnormalities Neutropenia is common Elevated protein is common Atazanavir (Reyataz) causes high bilirubin Zidovudine (Retrovir) causes a high MCV Cobicistat (Tybost, Prezcobix, Evotaz, Stribild, Genvoya) can cause a false elevation in Cr

36 Objectives 1. Discuss the current status of the statewide, nationwide and worldwide HIV/AIDS epidemics. 2. Describe the impact of HIV on the management of the pregnant patient. 3. Discuss Pre- and Post-Exposure Prophylaxis for HIV.

37 Perinatal HIV Transmission Risk Untreated: Approx % AZT Monotherapy: 8% Prophylactic C/S: 3-5% Combination ART: <1%

39 ACTG 076 Trial (U.S. and France) ZDV vs. placebo ZDV mono-therapy starting at weeks, IV ZDV intrapartum, and neonatal ZDV for 6 weeks Mother-to-Child-Transmission (MCTC) at 18 months: 8.3% in the ZDV arm 25.5% in the placebo arm

Infiltrates subsequently dx d with PCP CD4 count: 6, HIV RNA Quant: 433,000

47 Case 2B: S.I. 34 y/o wife of S.Z. (who was diagnosed July, 2012) Delivered her second child in Sep, 2011 In December, 2011 presented to clinic and was diagnosed with pharyngitis. Fever, HA, ST, rash, and adenopathy In August, 2012 was found to be HIV positive CD4: 1191, HIV RNA: 3,400 Infant was HIV negative

48 ART: Who Gets Treated in Pregnancy? Everybody Those who require ART for their own health Those who need it only to reduce MTCT Especially Patients with acute sero-conversion Women diagnosed late in pregnancy

49 ART-Naïve Women Start immediately or as soon as possible Factors to consider Genotype CD4 count N/V related to pregnancy Patient readiness/ability to adhere NRTI backbone with one or more NRTI s that have high transplacental levels: ZDV, 3TC, FTC, TDF, ABC Nevirapine can be used is CD4 < 250

50 Women on ART Who Become Pregnant If the regimen is working, keep taking it Efavirenz: Okay to continue despite known risk of neural tube defects Nevirapine: Okay regardless of CD4 ARV resistance testing for anyone with detectable viremia (HIV RNA of > 500 copies)

51 Pre-conception Counseling in HIV Basic pre-conception issues The good old days of HIV care Risk/benefit Turkey basters and other creative options Sperm-washing Current practice: PrEP Tenofovir/emtracitabinedaily for the uninfected partner Timed intercourse; use condoms all the rest of the time

52 Mode of Delivery Scheduled C/S at 38 weeks if HIV RNA>1,000 (or unknown) Scheduled C/S not recommended if HIV RNA<1,000. (No additional risk reduction is conferred)

53 What About SROM/Labor in Patients Scheduled for C/S? Duration of ROM/labor 1996 study showed 4 hours of ROM was a significant cut-off 2001 study showed 2% increase in MTCT/hour of ROM HIV RNA level Current ART regimen

54 Intrapartum Prophylaxis Continue antepartum ART regardless of mode of delivery IV Zidovudine? Yes, if HIV RNA >1,000 (or unknown) near delivery Not required if HIV RNA <1,000 near delivery (and patient is on ART with no concerns of poor adherence) Zidovudine dose: 2 mg/kg IV over the first hour, then 1 mg/kg/hruntil cord clamp

55 OB Procedures in HIV: Avoid if Possible Antepartum: Amniocentesis Intrapartum: AROM Routine use of fetal scalp leads IUPC placement? Operative delivery Forceps Vacuum Episiotomy

56 No-Prenatal-Care Patients Presenting in Labor Rapid HIV test ASAP If positive, treat as if infected (don t wait for confirmatory test) Continue to treat infant as if mom has HIV until confirmatory test proves negative

57 What do I need to know about HAART? (Highly Active Anti-Retroviral Therapy) DRUG INTERACTIONS DRUG INTERACTIONS DRUG INTERACTIONS DRUG INTERACTIONS DRUG INTERACTIONS DRUG INTERACTIONS Be aware of side effects

58 OB Drug Interactions Methergine levels increased by Protease Inhibitors and Cobicistat-containing ARV s (CYP3A4 Inhibitors) Norvir (ritonavir) Reyataz (atazanavir) Prezista (darunavir) Kaletra (lopinavir/ritonavir) Stribild, Tybost, Prezcobix, Evotaz, Genvoya Risk of ergot toxicity, severe vasospasm, increased BP, and ischemia

59 OB Drug Interactions, Con t Methergine levels decreased by CYP3A4 inducers, leading to lack of effectiveness of methergine Sustiva, Atripla (efavirenz) Intelence (etravirine) Viramune (nevirapine) Oxytocin, misoprostol (Cytotec) and Hemabate (carboprost tromethamine) do not interact with HIV medications and may be used in women taking ART

60 Hormonal Contraception? Efavirenz, most protease inhibitors, Stribild, and to a lesser extent, nevirapine all decrease hormonal contraception levels. Raltegravir, dolutegravir and etravirine: no impact Maraviroc: serum levels increased when combined with estrogens

61 OCP s and Atazanavir Atazanavir/ritonavir: Decreases ethinyl estradiol, increases norgestimate. Need to use an OCP containing no less than 35 mcg ethinyl estradiol Atazanavir alone: Increases ethinyl estradiol 48% and increases norethindrone 110%. Need to use an OCP containing no more than 30 mcg ethinyl estradiol.

62 Drug Interactions Resources Epocrates Arv.ucsf.edu Call your clinical pharmacist

63 What About the Baby?

68 Perinatal Guidelines

69 Objectives 1. Discuss the current status of the statewide, nationwide and worldwide HIV/AIDS epidemics. 2. Describe the impact of HIV on the management of the pregnant patient. 3. Discuss Pre- and Post-Exposure Prophylaxis for HIV.

70 Post-Exposure Prophylaxis What do I tell my patient? What do I tell my spouse? What do I tell my self?

71 Reported Blood and Body Fluid Exposures by Profession Nurses: 48.6% Residents and fellows: 7.7% Attendings: 7.7% Non-lab techs: 4.5% Resp. therapists: 3.6% CNA s: 3.2%

72 Occupational Exposure: Risk of HIV Transmission Percutaneous: 20/6,135 (0.33%) Mucosal: 1/1,143 (0.09%) Intact Skin: 0/2,712

73 Fear the Fluids? Implicated fluids: blood, semen, vaginal secretions and fluids with visible blood. Potentially infectious: CSF, synovial, pleural, peritoneal, pericardial, and amniotic fluid. Considered safe: feces, nasal secretions, saliva, gastric secretions, sputum, sweat, tears, urine, and vomitus.

74 Estimated Per Act Risk of HIV Acquisition by Exposure Route (per 10,000 exposures) Blood transfusion: 9,000 Needle sharing (IVDU): 67 Receptive/insertive anal IC: 50/6.5 Needle stick: 30 Receptive/insertive penile/vaginal IC: 10/5 Receptive/insertive penile/oral IC: 1/0.5

75 Sexual Assault Risks and benefits of HIV prophylaxis should be discussed with every sexual assault patient No good data, but case reports of HIV seroconversion from sexual assault exist

76 HIV in Sexual Assault: A Little Perspective Risk of transmission from single episode of consensual vaginal intercourse with HIV positive man: 0.1% Risk of transmission from single episode of consensual anal intercourse with HIV positive man: 2%

77 High Risk Sexual Assault Male on male rapists Location in a high-prevalence region or country Multiple assailants Anal sexual assault Sexual assaults where either the assailant or the victim has trauma, bleeding or genital lesions

78 Post-Exposure Prophylaxis (PEP) Usually NOT indicated Rapid HIV test for source patient, if possible Initiation: sooner is better Goal is within 1-2 hours Benefit decreased after hours Not recommended after 72 hours Duration: 4 weeks (arbitrary) PEPline:

79 Pre-Exposure Prophylaxis (PrEP) Tenofovir/emtracitabine (Truvada) approved in 2012 for use in HIV-uninfected individuals at substantial risk of HIV acquisition. HIV sero-disconcordant couples HIV negative partner in a couple wishing to conceive Criteria for PrEP Proven to be HIV-negative Must be able to strictly adhere to a daily med regimen Must be tested for HIV at least every 3 months
