Acute HIV Syndrome: 1-8 weeks Fever 96% Rash 70% Sore Throat 70% Adenopathy 74% Myalgias 54% Headache 32% Diarrhea, N-V, malaise, thrush, hepatosplenomegaly, neuro sx (meningitis/neuropathy, facial palsy) Oral/Genital Ulcers -- Specific
Counseling and Testing Who and when to test Types of tests
Exposures in the Occupational Setting Needlestick 0.03 percent Risk Stratification a. Deep injury b. Visible blood c. Device used in artery or vein d. Advanced disease
Exposures in the Occupational Setting Treatment (PEP) reduced transmission 80% Zidovudine plus lamivudine +/- protease inhibitor Other regimens for exposures from source patients with documented or possible ARV drug resistance
Routine Health Care Medical/Psychosocial/Family History Physical Examination Markers of HIV Disease Progression • CD4+ (T-helper) lymphocyte count • Viral load
Labs (Routine) CD4+ Urinalysis (?) Viral load+ CXR CBC + Platelets + Sed rate Serum chemistries + LDH Syphilis serologies +Cryptococcal antigen Toxoplasmosis titre (?) + G6PD Lipid profile
Other Immunizations, including influenza vaccine, pneumovax, measles, + hepatitis B No OPV in families with HIV positive person Pap smear: 6 mos x2; 12 mos PPD (5 mm) Anergy testing not recommended: assess risk Prophylaxis not indicated for PPD negatives with risk factors only
Combination Antiretroviral Therapy Indications • CD4+ 350-200 cells/uL • Viral load > 55,000 copies • Symptomatic disease • Decision must be individualized
Reverse transcriptase inhibitors (RTIs) • Zidovudine (AZT, ZVD, Retrovir) • Didanosine (ddI, Videx or Videx EC) • Zalcitabine (ddC, Hivid) • Stavudine (d4T, Zerit) • Lamivudine (3TC, Epivir) • Abacavir (Ziagen)
Protease inhibitors (PIs) • Nelfinavir (Viracept) • Indinavir (Crixivan) • Saquinavir (Fortovase) • Ritonavir (Norvir) • Amprenavir (Agenerase) • "Boosted“ regimens: Ritonavir plus saquinavir, indinavir, nelfinavir, abacavir, or lopinavir 400 mg (Kaletra); nelfinavir plus indinavir or saquinavir.
Non-nucleoside reverse transcriptase inhibitors (NNRTIs) • Efavirenz (Sustiva) • Nivarapine (Viramune) • Delavirdine (Rescriptor)
Nucleotide reverse transcriptase inhibitor • Tenofovir (Viread)
Indications of response to ARVs Viral load decrease CD4 count increase Some effect within 4-6 weeks CD4+ increase within 2-4 months Ideal: undectectable by 4-6 months
Treatment failure Adherence problems Drug interactions; inadequate drug delivery Resistance: de novo during treatment off treatment Resistance testing – genotypic, phenotypic
Changing Therapy Viral load increase; CD4+ decrease Progressive disease Change 2 or more drugs Goals of therapy: suppression? non-detectable viral load?
Complications of ARV therapy Lipodystrophy, lipid abnormalities Lactic acidosis Glucose intolerance Activation or reactivation of disease (immune reconstitution)
Drug interactions • Among ARVs • Special considerations with anti-tuberculosis therapy, especially with rifampin
Prophylaxis against OIs(Opportunistic Infections) Pneumocystis carinii < 200 CD4+ Toxoplasma gondii < 100 CD4+ M. avium complex (MAC) < 50 CD4+ M. tuberculosis Any CD4+
Prophylaxis Not Required: • Fungal infections • HSV • CMV
Discontinuation of primary prophylaxis with effective ARV therapy Pneumocystis carinii >200 for >3 months Toxoplasma gondii >100 for > 3 months M. avium complex (MAC) >100 for > 6 months following 12 months of therapy
Candidal infections • Oral, vaginal, etc infections • Esophageal candidiasis • Systemic candidal infections
Acute PCP Trimethoprim-Sulfamethoxazole 15 mg TMP/75 mg SMX per kg (Septra,TM BactrimTM) daily given in 3 - 4 doses po or as 1 - 2 hour IV infusion for patients with PaO2< 70 add: Methylprednisolone (IV) 40 mg bid for 5 days followed by or 40 mg q d for 5 days followed by Prednisone (po) 20 mg q d for 11 days (can also be tapered to zero over last 11 days)
