If current guidelines used, HIV could have been diagnosed up to 8 years earlier Slide 17 Learning Points This patient came from a country of low HIV prevalence and was probably not believed to be at risk of HIV infection Because of this the otherwise excellent medical teams looking after her presumably did not think of HIV even though the diagnosis seems obvious with hindsight However, the suspected PUO and Hepatitis B and TB diagnoses were a red flag for possible HIV infection A perceived lack of risk should not deter you from offering a test when clinically indicated Slide 18 Antiretroviral therapy (ART) has transformed treatment of HIV infection The benefits of early diagnosis of HIV are well recognised - not offering HIV testing represents a missed opportunity UK guidelines recommend screening for HIV in adult populations where undiagnosed prevalence is >1/1000 as it has been shown to be cost-effective HIV screening should be a routine test on presentation of PUO or weight loss of otherwise unknown cause HIV screening should be routine in services for patients diagnosed with Hepatitis B and TB Key messages Slide 19 19 Also contains UK National Guidelines for HIV Testing 2008 from BASHH/BHIVA/BIS Available from: enquiries@medfash.bma.org.uk or 020 7383 6345
