What do we have to ask a patient before starting HAART? Are you ready?
Goals of HAART therapy Complete Viral Suppression Minimize Side Effects GI Body Morphing Lipids Minimize Pill Burden Once Daily
starting medications guide At least 3 medications At least 1 PI, NNRTI, Entry Inhibitor or Integrase Inhibitor Avoid combos of Zerit/Videx Zerit/AZT
Starting medication anchor medications Efavirenz Atazanavir/Ritonavir Darunavir/Ritonavir Raltegravir
Starting guideline NUKES Truvada
Treatment Regimens for Antiretroviral Naïve Patients Efavirenz/tenofovir/emtricitabine (Atripla) Atazanavir/ritonavir/tenofovir/emtricitabine Darunavir/ritonavir/tenofovir/emtricitabine Raltegravir/tenofovir/emtricitabine
Treatment Regimens for Antiretroviral Pregnancy Lopinavir/ritonavir/zidovudine/lamivudine (because we have more experience with this combo in pregnant women
Rules for medication intolerance Replace the medication with another in THE SAME FAMILY
Treatment Therapies to Avoid d4T +ZDV Monotherapy* All Nuke Regimens Epivir + Emtriva NNRTI + NNRTI d4T + ddI Ritonavir + Cobicistat
What is Immune Reconstitution Inflammatory Syndrome (IRIS)? Side Effect of Therapy Related to rapid response to HAART tx Rapid decrease in Viral Load Rapid increase in CD4 cell count
How does IRIS typically present? Previously undiagnosed Opportunistic Infection (OI) Inflammatory response to Previous OI
what can we do if IRIS occurs? give steroid, nsaid or stop HAART
What is salvage therapy? Cocktail therapy that is necessary due to viral escape. Can be 1st salvage Can be “Deep Salvage
What are the rules of salvage therapy? Resistance Testing Genotype/Phenotype New “Family” of Drugs New Medications At least 2 with full activity Keep Epivir/Emtriva
How can pharmacists prevent salvage therapy? avoid drug interactions, get the right medication and promote adherance
Why Adherence is important Need 95% or better Resistance!!! Can have class effects Next combo less effective More side effects Viral Progression
HIV Treatment in Pregnancy: On Therapy Prior to Pregnancy Undetectable Viral Load Don’t Mess With Efavirenz Detectable Viral Load Viral Resistance Testing Adherence Get Viral Load Undetectable
HIV Treatment in Pregnancy: Not On Therapy Prior to Pregnancy HIV Viral Resistance Testing Treat Without Regard to CD4 Cell Count Start as Soon as Possible Morning Sickness Medications to Avoid Efavirenz Nevirapine if CD4 >250
Treatment Points for Delivery If Mother’s Viral Load >1000 copies/ml Scheduled C-Section IV Zidovudine 2mg/kg Load, 1mg/kg/hr until Delivery Avoid Breaking Skin of Fetus Oxygen Probes Forceps/Suction
HIV and Pregnancy treatment for fetus Fetus to Receive Zidovudine for 6 Weeks 2mg/kg oral Zidovudine every 6 hours Start 6 to 8 hours after birth
PrEP- Pre-exposure Prophylaxis Used in HIV negative patients Prior to sex Oral medication therapy taken daily
nPEP-Nonoccupational Postexposure Prophylaxis Used in HIV negative patients after risk of exposure, usually sexual
PEP- Occupational Exposure Postexposure Proph Most commonly associated with EMS and health care personnel
PrEP medication Truvada approved for PrEP by FDA 7/2012 Truvada 1 tablet daily Trials supporting PrEP iPrEx- international MSM TDF2- heterosexual men and women Partners PrEP- heterosexual sero-discordant couples Protection related to adherence
nPEP: HIV negative patient potentially exposed to HIV Needs to start within 72 hours of exposure (prefer within 24 hours) Kaletra/Combivir Atripla or Efavirenz/Combivir Treatment for 28 days
PEP Postexposure prophylaxis for healthcare workers Remember test for HIV, HepB and HepC PEP subject should be HIV Treatment within 72 hours of exposure Treatment for 28 days
PEP Treatment Regimens Severity based on Viral load or experience of source Kind of exposure Less severe exposure 2 drug regimen Combivir preferred More severe exposure 3 drug regimen Kaletra/Combivir
What is STI? Strategic Treatment Interruption Interruption of therapy at a scheduled interval Time off of therapy Pill Fatigue Break between regimens
