Abstract
To determine whether procalcitonin (PCT) levels could help discriminate isolated viral from mixed (bacterial and viral) pneumonia in patients admitted to the intensive care unit (ICU) during the A/H1N1v2009 influenza pandemic.
A retrospective observational study was performed in 23 French ICUs during the 2009 H1N1 pandemic. Levels of PCT at admission were compared between patients with confirmed influenzae A pneumonia associated or not associated with a bacterial co-infection.
Of 103 patients with confirmed A/H1N1 infection and not having received prior antibiotics, 48 (46.6%; 95% CI 37–56%) had a documented bacterial co-infection, mostly caused by
PCT may help discriminate viral from mixed pneumonia during the influenza season. Levels of PCT less than 0.8 μg/l combined with clinical judgment suggest that bacterial infection is unlikely.

discriminate isolated viral from mixed (bacterial and viral) pneumonia in patients admitted to the intensive care unit (ICU) during the A/H1N1v2009 influenza pandemic.</p></sec><sec><title>Methods</title><p>A retrospective observational study was performed in 23 French ICUs during the 2009 H1N1 pandemic. Levels of PCT at admission were compared between patients with confirmed influenzae A pneumonia associated or not associated with a bacterial co-infection.</p></sec><sec><title>Results</title><p>Of 103 patients with confirmed A/H1N1 infection and not having received prior antibiotics, 48 (46.6%; 95% CI 37–56%) had a documented bacterial co-infection, mostly caused by <italic>Streptococcus pneumoniae</italic> (54%) or <italic>Staphylococcus aureus</italic> (31%). Fifty-two patients had PCT measured on admission, including 19 (37%) having bacterial co-infection. Median (range 25–75%) values of PCT were significantly higher in patients with bacterial co-infection: 29.5 (3.9–45.3) versus 0.5 (0.12–2) μg/l (<italic>P</italic> < 0.01). For a cut-off of 0.8 μg/l or more, the sensitivity and specificity of PCT for distinguishing isolated viral from mixed pneumonia were 91 and 68%, respectively. Alveolar condensation combined with a PCT level of 0.8 μg/l or more was strongly associated with bacterial co-infection (OR 12.9, 95% CI 3.2–51.5; <italic>P</italic> < 0.001).</p></sec><sec><title>Conclusions</title><p>PCT may help discriminate viral from mixed pneumonia during the influenza season. Levels of PCT less than 0.8 μg/l combined with clinical judgment suggest that bacterial infection is unlikely.</p></sec></div></front><back><div1

Levels of PCT at admission were compared between patients with confirmed influenzae A pneumonia associated or not associated with a bacterial co-infection.</p></sec><sec><title>Results</title><p>Of 103 patients with confirmed A/H1N1 infection and not having received prior antibiotics, 48 (46.6%; 95% CI 37–56%) had a documented bacterial co-infection, mostly caused by <italic>Streptococcus pneumoniae</italic> (54%) or <italic>Staphylococcus aureus</italic> (31%). Fifty-two patients had PCT measured on admission, including 19 (37%) having bacterial co-infection. Median (range 25–75%) values of PCT were significantly higher in patients with bacterial co-infection: 29.5 (3.9–45.3) versus 0.5 (0.12–2) μg/l (<italic>P</italic> < 0.01). For a cut-off of 0.8 μg/l or more, the sensitivity and specificity of PCT for distinguishing isolated viral from mixed pneumonia were 91 and 68%, respectively. Alveolar condensation combined with a PCT level of 0.8 μg/l or more was strongly associated with bacterial co-infection (OR 12.9, 95% CI 3.2–51.5; <italic>P</italic> < 0.001).</p></sec><sec><title>Conclusions</title><p>PCT may help discriminate viral from mixed pneumonia during the influenza season. Levels of PCT less than 0.8 μg/l combined with clinical judgment suggest that bacterial infection is unlikely.</p></sec></div></front><back><div1
