  5. HIV Testing Behavior • Detection of AHI is rare – about 4% of all cases in NC • 25% of HIV infections in the U.S. are unrecognized (Fleming PL. 9th CROI, 2002) • Risk awareness is key • Onset of symptoms or illness acts as a cue for testing • 42% of HIV positive in U.S. tested due to illness (MMWR 2003) • Factors influencing detection of AHI are not well understood - a key period for public health intervention

  6. Viral Loads at Initial Detection: NCFiscus et al. 2004 10 9 8 median 209,183 7 6 29,347 5 4 3 2 1 0 Established HIV+ (n=66) Acutely HIV + (n=21)

  7. NC Approach to AHI DetectionSTAT Program • Screen all HIV Ab negative or WB indeterminate blood for HIV RNA • Review of all community cases - Antibody (Ab) negative, HIV RNA (+) - Ab+ with a history of an HIV Ab (-) within 3 mo - Ab+ with recent acute symptoms or STD symptoms within 1 mo

  8. The Screening and Tracing Active Transmission (STAT) Program • Possible AHI clients are notified by disease investigation specialists (DIS) within 72 hours • Confirmatory testing • Referrals to care • Partner notification & testing • Interview with AHI clients includes symptoms, STD symptoms and diagnoses, and partner information

  9. Acute HIV Incubation Periods N=31 Median [Range] = 14 d [5-30] Mean (+/- SD) = 15 d+/- 6.3 Sources: Pilcher JAMA 2001 Lindback AIDS 2001 Borrow Nat Med 1997 Schacker AIM 1996 10 8 6 Frequency 4 2 0 7 14 21 28 Days from Unique Sexual Exposure to Onset of Symptoms

  10. Acute Retroviral Symptoms • 45 clients (59%) had symptoms either at testing or in the 4 weeks prior to testing • 87% had ≥2 sx(51% of total) • 58% had ≥3 sx (43% of total)

  14. NC HIV Testing in STD Clinics • HIV testing offered to all STD clients at each new visit • Policy to offer opt-out HIV testing • Fast tracked or expedited testing for person who present with documented symptoms compatible with Antiretroviral Syndrome (ARV) and other high risk behaviors such as an STI, multiple sex partners or anal sex. • Contact acute HIV Program 919 – 966-8533 for review and possible expedited testing.

  15. Fast Track or Expedited Testing • Fast-track HIV RNA testing is indicated if the following criteria are met within the preceding 4 weeks and documented by a medical provider: • HIV risk exposure * • Documented fever ≥100.5°F or >38.0°C Contact acute HIV Program 919 – 966-8533

  16. Care of AHI at UNC • Immediate appointment with an ID specialist for evaluation • Treatment Options • No standard guidelines for treatment • Research Options • Treatment studies (Atripla) • Observational studies • Standard of care testing and large blood draws
