Case 7: November 2008

Case 7: November 2008

On admission to hospital 1: • Unwell • Right pleural rub • Bronchial breathing at Right base • PaO2 = 9.5 kPa (on air) • CXR = Right lower lobe pneumonia • Blood cultures confirmed

Strep. pneumoniae

Case 7: November 2008

• Given benzylpenicillin/clarithromycin → recovered • Persistently elevated ALT (=71, Normal<50) • USS normal • Hepatitis A, B, and C serology negative • Seen for follow up in OPD, 2 weeks after • Hospital discharge. • LFTs now normal • Was well → no further follow-up 4

Case 7: April 2009

Re-presents to ED of hospital 1 3-day history of: • Cough with rusty sputum • Fever with sweats • Chills • Headache • Reported 8kg weight loss over previous 5 months 5

Case 7: April 2009

OE: • Signs of Left upper lobe consolidation • CXR = L upper lobe pneumonia • Sputum/blood culture = negative • Peripheral blood WBC = 12.3 x10 9 /L • Treated empirically for bacterial pneumonia • → recovered • Patient DNAd follow-up appointment 6

Case 7: June 2009

• Moved to new job • Now registered with GP • Visits GP - reports she is unwell, lethargic • GP finds nil abnormal on examination • Blood tests: Monospot negative,Hb 9.9 g/dl, MCV normal, ESR 50 mm/hr • Referred by GP to Haematology OPD of hospital 2

b efore being seen in OPD… 7

Case 7: July 2009

Brought to ED of hospital 2 by her employer 8 OE: • 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 9

Case 7: July 2009

On ICU: • 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 10

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 11

Q: At which of her healthcare interactions could/should HIV testing have been performed?

When she first presented with 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?

4 missed opportunities!

If current guidelines had been followed, HIV could have been diagnosed 9 months earlier

Nov 2008 April 2009 June 2009 June 2009 July 2009 Admitted, PUO, severe bacterial pneumonia, (negative Hepatitis A, B and C serology) Admitted, recurrent bacterial pneumonia, weight loss Registered with GP Seen by GP with lethargy, anaemia and raised ESR Admitted, respiratory distress HIV diagnosed: severe PCP: CD4 100, VL 380,000 Inpatient 19 days

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 22
