At least 4 missed opportunities!
If current guidelines used, HIV diagnosed 2.5 years
earlier

seborrhoeic dermatitis
2004-2005 Seen in Gastroenterology OPD

April 2006 PCP, CMV, HSV, oral candidiasis
HIV diagnosed (CD4 40)

Learning Points
• This patient had numerous investigations and a long ITU
stay, causing him and his family much distress and
costing the NHS thousands of pounds
• Because of his nadir CD4 of 40 he has an increased risk
of potential problems despite control of his HIV now
• He did not disclose any risk factors when his initial
medical history was taken
• Because of this the otherwise excellent medical teams
looking after him did not think of HIV even when the
diagnosis seems obvious with hindsight
• A perceived lack of risk should not deter you from
offering a test when clinically indicated
15
Key messages
• 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 routine offer of an HIV test
for patients with lymphopenia
• HIV screening should become a routine test performed
whenever there is a clinical indicator such as chronic
diarrhoea or weight loss
• Some patients may not disclose that they have put
themselves at risk of HIV infection in the past
