dc.description.abstractThe diagnostic value of C-reactive protein (CRP) admission serum levels as an indicator of the aetiology of community acquired pneumonia (CAP) was evaluated. A cohort of 1,222 patients with CAP was assessed. CRP levels were analysed in 258 patients with a single aetiological diagnosis. The mean CRP values in patients with pyogenic, atypical, viral and Legionella pneumophila pneumonia were: 16 mg?dL-1 , 13 mg?dL-1 , 14 mg?dL -1 and 25 mg?dL-1 , respectively. CRP levels were not significantly different among patients outcome research team (PORT) groups (19 mg?dL -1 in groups I–II, 16 mg?dL-1 in group III and 16 mg?dL -1 in groups IV–V. A cut-off point of 25 mg?dL-1 had a sensibility, specificity, positive predictive value and negative predictive value of 0.6, 0.83, 0.3, and 0.94, respectively. After controlling for age and PORT score, the odds of having a CRP level w25 mg?dL-1 was 6.9 times higher in patients with L. pneumophila pneumonia than in those with non-L. pneumophila pneumonia. Patients with Legionella pneumophila pneumonia had higher C-reactive protein levels than those with pneumonia of any other aetiology, independently of severity of infection. Being a cheap and readily available test, C-reactive protein may be a useful adjunctive procedure in the diagnosis of community acquired pneumonia.es
