UNLABELLED: Activity of natural streptogramin (NSG) appears well adapted to pathogens responsible for CAP. The goal of this multicenter pilot study was to bring first data about efficacy of NSG in treatment of CAP. PATIENTS METHOD: Ten days of a NSG (1 gr b.i.d. or t.i.d.) regimen was administered to 46 hospitalized adult patients for CAP defined with fever > 38 degrees C, respiratory symptoms and X-ray opacity. Severely ill patients were excluded. A broncho-pulmonar sample (expectoration or trantracheal aspiration or protected distal sample) was performed in all patients. RESULTS: two patients were excluded because of pulmonary embolism (n = 1) or tuberculosis (n = 1) and 44 patients were analyzed. 50% of them had associated disease, 20% had failure of prior antibiotherapy. At inclusion, mean fever was 39.2 +/- 0.7 degrees C, respiratory rate was 22 +/- 5/mn, PaO2 was 74 +/- 10 mmHg, chest X-ray showed bilateral opacity in 16%, unilateral in 84% and pleural fluid level in 6 cases. Etiological diagnosis was determined in 70% of cases. Streptococcus pneumoniae (n = 14), Haemophilus influenzae (n = 5), Legionella pneumophila (n = 2), Mycoplasma pneumoniae (n = 2) and Chlamydia psittaci (n = 1) were the most frequent isolated pathogens. 40 patients (91%) were cured with NSG and delay to obtain apyrexia was 4.4 +/- 3.9 days. NSG was stopped in 4 patients: 1 clinical and bacteriological failure (Klebsiella pneumoniae), 2 clinical failures (1 pneumococcus with purulent pleurisy, 1 pneumococcus with worsening of respiratory status), 1 patient with resistant H. influenzae strain in spite of favourable clinical evolution. NSG was well tolerated in 86% of patients. CONCLUSION: these data invite to carry on evaluation of first line therapy of CAP with NSG.
