Cefepime versus ceftazidime in the treatment of lower respiratory tract infections.

The objective of the study was to compare the safety and efficacy of cefepime and ceftazidime in the treatment of community acquired lower respiratory tract infections of moderate intensity. Eighty-six patients were randomized at a 2:1 ratio to receive respectively cefepime 1 g b.i.

Pulmonary edema and acute hypercapnic respiratory failure treated with bi-level nasal-CPAP: case report.

Noninvasive mechanical ventilation has been suggested for the treatment of patients with respiratory failure. We describe the case of a patient affected by bilateral cystic bronchiectasis and acute hypercapnic respiratory failure, due to a cardiogenic pulmonary edema, successfully treated with bi-level nasal-CPAP. This report suggests that in some cases noninvasive ventilatory support may mean avoiding tracheal intubation, even with critically ill patients.

Lower respiratory tract inflammation in chronic bronchitis. Evaluation by bronchoalveolar lavage and changes associated with treatment with Immucytal, a biological response modifier.

Chronic bronchitis (CB) is characterized by inflammatory changes in the bronchial tissue and by recurrent bronchitis exacerbations. In addition, defective systemic and local immune mechanisms have been demonstrated and biologic response modifiers (BRMs) have been recently introduced for clinical use in patients with CB. We studied 24 patients with CB by bronchoalveolar lavage (BAL), before and after a 4-week treatment protocol with inhaled Immucytal (Pierre-Fabre Pharma Srl, Milan, Italy), a BRM composed of bacterial ribosomal fractions and membrane proteoglycans.

Mast cells in the airway lumen and bronchial mucosa of patients with chronic bronchitis.

In order to evaluate the degree of mast cell infiltration and determine their granulation state in the airways of patients with chronic bronchitis, bronchoscopy was performed in 25 chronic bronchitis subjects (10 smokers and 15 ex-smokers) with mucoid sputum production and in seven normal nonsmoking control subjects. Bronchoalveolar lavage and bronchial biopsies were examined using histochemical techniques. Subjects with chronic bronchitis had higher numbers of mast cells both in the epithelium (1.
