[Treatment of community-acquired pneumonia by pristinamycin (Pyostacine 500). Results of a non comparative open study].

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.

Determinants of immediate survival among chronic respiratory insufficiency patients admitted to an intensive care unit for acute respiratory failure. A prospective multicenter study. The French Task Group for Acute Respiratory Failure in Chronic Respiratory insufficiency.

In this study, 322 patients were evaluated with two aims: determination of identifiable factors at the time of admission to an ICU that predict short-term survival. Application of the SAPS to this population. Characteristics of patients were as follows: age, 65.5 +/- 14.5 years; COLD, 45 percent; restrictive, 13.4 percent; obstructive and restrictive CRI, 13 percent; asthma progressing to CRI, 11.2 percent; diffuse bronchiectasis, 7.2 percent; neuromuscular diseases, 2.2 percent; others, 8 percent. Cachectic patients, those confined to home, those with initial coma or those who required MV had a higher percentage of M. The SAPS at admission was higher in those patients who died; however, there was no link between the SAPS and M. Prognostic factors in ARF complicating CRI and identifiable at the time of admission to an ICU are few and reflect severity of chronic respiratory disease; SAPS appears to be less useful in ARF complicating CRI.

Nasal mask ventilation in acute respiratory failure. Experience in elderly patients.

Nasal mask ventilation (NMV) has been used successfully in chronic restrictive respiratory failure and more recently in acute exacerbations of chronic obstructive pulmonary disease (COPD). This study aimed to evaluate the possible role of NMV in acute respiratory failure (ARF) episodes when mechanical ventilation with endotracheal intubation is questionable. Thirty patients (age, 76 +/- 8.1 years) were treated by NMV during ARF episodes (COPD, 20; other chronic respiratory failure [CRF], 5; chronic heart failure [CHF], 4). All patients were hypoxemic (PaO2, 5.85 +/- 1.62 kPa) and hypercapnic (PaCO2, 8.63 +/- 1.89 kPa) with respiratory acidosis (pH, 7.29 +/- 0.08). In all cases, clinical or physiologic parameters indicated the need for mechanical ventilation, but endotracheal intubation was either not applied because of the age and the physiologic condition of the patients (17 cases) or was postponed (13 cases). NMV was performed using a volume-cycled ventilator and a customized nasal mask. Ventilation was continuous during the first 12 hours and the following nights and was then intermittent during the day. Twenty-one patients improved clinically, within a few hours. Progressive correction of arterial blood gases was observed: PaO2 increased during the first hour, but PaCO2 decreased more slowly. Eighteen patients were able to be successfully weaned from NMV. Twelve patients failed to improve despite NMV: eight of them died and four required endotracheal intubation. There was no difference in the success rate between patients in whom endotracheal ventilation was contraindicated or postponed. Clinical tolerance was satisfactory in 23 patients and poor in seven patients. A return to the respiratory condition was observed in the surviving patients with subsequent discharge from hospital. NMV therefore successfully treated respiratory distress initially in 60 percent of the 30 patients. These results suggest that NMV could be a possible alternative in the treatment of ARF, even in very ill patients, when endotracheal ventilation is controversial or not immediately required.

[Sarcoidosis simulating a pulmonary veno-occlusive disease].

We report the case of a man of 43 years old presenting with sarcoidosis which produced pulmonary hypertension and respiratory failure without radiological evidence of interstitial fibrosis. In spite of treatment with steroids and corticosteroids (1 mg/kg) there was progression over 2 1/2 years to respiratory failure and irreversible right heart failure and the death of the patient. At autopsy the pulmonary veins were obliterated by non caseating granulomas and there were minimal fibrotic parenchymal lesions. To our knowledge this is only the second case of sarcoidosis resulting in a veno occlusive pulmonary disorder.
