Signs of Left upper lobe consolidation
CXR = L upper lobe pneumonia
Sputum/blood culture = negative
Peripheral blood WBC = 12.3 x109/L
Treated empirically for bacterial pneumonia
→ recovered
Patient DNAd follow-up appointment

Moved to new job
Now registered with GP

Severely unwell
Cyanosed
Tachypnoeic (resp rate = 26/min)
Pyrexial, T = 38.4 degC
Also - ED ST2 notices oral candida and oral
hairy leukoplakia on tongue
Case 7: July 2009
Investigations:
• PaO2 (on air) = 6.9 kPa
• CXR = marked bilateral infiltrates
• ST2 queries underlying HIV infection
- begins empirical therapy for PCP
• Patient transferred from ED to ICU

Case 7: July 2009
On ICU:
•
•
•
•
•
•
•
10
With supplemental oxygen (FiO2 = 60%) →
Better oxygenated
ICU Consultant offers patient an HIV test
Offer accepted
HIV test is positive
CD4 count = 100 cells/µl
Viral load = 380 000 copies/ml
Case 7: July 2009
• PCP treatment continued
(high-dose co-trimoxazole and methyprednisolone) →
improvement in oxygenation
• On day 4 of ICU admission patient deteriorates, with
worsening oxygenation following fibreoptic bronchoscopy
and BAL (confirms PCP)
• CXR excludes pneumothorax
• CPAP given for 3 days→ patient improves
• Discharged to general ward after 8 days on ICU
• Began ARVs after 14 days of PCP therapy → continued
improvement
• Discharged from hospital on day 19

Q: At which of her healthcare
interactions could/should HIV
testing
been
When
she firsthave
presented
withperformed?
severe bacterial
pneumonia?
When tests for viral hepatitis were performed?
When she re-presented with bacterial pneumonia and
weight loss?
When she registered with a GP?
When she presented to GP with lethargy and was
found to have anaemia and a raised ESR?
Should she have been referred to GUM to see a
trained counsellor before HIV testing?

Learning Points
• This patient came from an area of high HIV prevalence,
but was not offered an HIV test in several contacts with
healthcare services
• This patient had numerous investigations including 3
admissions and an ITU stay, causing her much distress
and costing the NHS thousands of pounds
• Because of her nadir CD4 of 100 she has an increased
risk of potential problems despite control of her HIV now
• A perceived lack of risk should not deter you from
offering a test when clinically indicated
21
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 screening for HIV in adult
populations where undiagnosed prevalence is >1/1000 as
it has been shown to be cost-effective
• UK guidelines recommend universal HIV testing for
patients from groups at higher risk of HIV infection
• HIV screening should be a routine test on presentation of
bacterial pneumonia, and PUO, anaemia or weight loss of
otherwise unknown cause
