Multicenter StudySevere community-acquired pneumococcal pneumonia. The French Study Group of Community-Acquired Pneumonia in ICU.
Streptococcus pneumoniae is the most frequent pathogen of severe community-acquired pneumonia (CAP) necessitating hospitalization. The main objective of this multicentre prospective study was to determine the value of clinical, biological, and radiological features for predicting pneumococcal etiology and to define prognostic factors. Streptococcus pneumoniae was isolated in 43/132 patients (33%) with CAP requiring ICU treatment. ⋯ Among the clinical, biological, and radiological features, fever > 39 degrees C, pleuritic chest pain, lobar distribution or alveolar consolidation, and an increase in immature granulocytes > or = 5% of WBC were more frequent in pneumococcal pneumonia than in other etiologies. Mortality was 35%. Fatal outcome was significantly related to the presence of impaired alertness, septic shock, mechanical ventilation, acute renal failure, and bacteremic pneumonia.
