amoxicillin-potassium-clavulanate-combination and Lung-Diseases

In order to assess the efficacy and safety of amoxicillin-clavulanate for the treatment of anaerobic lung infection, 40 patients with lung abscess or necrotizing pneumonia were given sequential amoxicillin-clavulanate therapy. All patients received intravenous amoxicillin-clavulanate (2 g/200 mg/8 h), which was switched to oral form (1 g/125 mg/8 h) after clinical improvement. Mean duration of antibiotic therapy was 43.5 days. Microbiological documentation was obtained in 53% of cases. All but 1 of the 48 microorganisms isolated were susceptible to amoxicillin-clavulanate. The drug was well tolerated by the patients and no severe adverse effects were observed. At the end of treatment all patients were considered cured. The 35 patients assessed at long-term follow-up visit remained disease-free.

Actinomycosis is a rare suppurative infection, subacute or chronic caused by bacteria of the genus Actinomyces.. A case study of 4 patients with prolonged respiratory symptoms. The clinical examination was poor in all cases. The CT-scan showed, in all cases, a suspicious tissue mass. The bronchoscopy diagnosis showed, in 2 cases, a tumor budding and was normal for the 2 other cases. Bronchial biopsies were negative in all cases. Before the prolonged symptomatology, the poor general condition, the endoscopic and the CT aspects; there was a suspect around a pulmonary neoplasia diagnosis, thus raising the need of a surgical treatment for diagnostic and therapeutic purposes. The anatomopathological examination of the resected specimen was in favour of the actinomycosis. The aim of these observations is to draw the attention to the radio-clinical, histological, therapeutic and evolutive aspects as well as the diagnostic difficulties of this condition.. The radio-clinical presentation of the actinomycosis is often misleading, thus a diagnostic confirmation is required before any useless surgical resection.

To describe clinicoradiologic and histopathologic features of bronchopulmonary actinomycosis and to determine whether hiatal hernia (HH) is a potential predisposing factor for bronchopulmonary actinomycosis.. We reviewed the medical charts of 10 patients who had bronchopulmonary actinomycosis between November 1, 2002, and January 31, 2008. Complete clinical data, radiologic studies (chest radiographs and computed tomographic scans), and histopathologic features were assessed to investigate clinical manifestations and predisposing factors related to bronchopulmonary actinomycosis.. The series consisted of 6 men and 4 women, with a mean age of 63.5 years; 8 of the patients were smokers. Cough and fever were the most common symptoms. Chest imaging showed mass-like consolidation in 4 patients, bronchial thickening or lung atelectasis with pleural thickening in 2 patients each, and perihilar irregular mass or multiple bilateral nodules in 1 patient each. Primary or metastatic lung cancer was suspected clinically in 8 of the 10 patients. Foreign body-related endobronchial actinomycosis was diagnosed in 6 patients, 5 of whom had HH; only 1 had gastroesophageal reflux-related symptoms. Because of bronchial obstruction, rigid bronchoscopy was performed in 3 patients, lobectomy in 2, and atypical resection in 1. Antibiotic therapy with amoxicillin was given to all patients, with resolution of actinomycosis.. Bronchopulmonary actinomycosis is a rare condition that mimics pulmonary malignancy on clinical and radiologic grounds. Diagnosis relies on an accurate patient history and histopathologic examination. Although further confirmation is required, esophageal HH appears to be a potential predisposing factor.

The recommended antibiotic prophylaxis by second-generation cephalosporins reduces the incidence of wound infection and empyema, but its effectiveness on postoperative pneumonias (POPs) after major lung resection lacks demonstration. We investigated risk factors and characteristics of POPs occurring when antibiotic prophylaxis by second-generation cephalosporin or an alternative prophylaxis targeting organisms responsible for bronchial colonization was used.. An 18-month prospective study on all patients undergoing lung resections for noninfectious disease was performed. Prophylaxis by cefamandole (3 g/24 h, over 48 hours) was used during the first 6 months, whereas amoxicillin-clavulanate (6 g/24 h, over 24 hours) was used during the subsequent 12 months. Intraoperative bronchial aspirates were systematically cultured. Patients with suspicion of pneumonia underwent bronchoscopic sampling for culture.. Included were 168 patients in the first period and 277 patients in the second period. The incidence of POP decreased by 45% during the second period (P = 0.0027). A significant reduction in antibiotic therapy requirement for postoperative infections (P = 0.0044) was also observed. Thirty-day mortality decreased from 6.5% to 2.9% (P = 0.06). Multivariate analysis showed that type of resection, intraoperative colonization, chronic obstructive pulmonary disease, gender, body mass index, and type of prophylaxis were independent risk factors of POP. A case control-study that matched patients of the two periods according to these risk factors (except for antibiotic prophylaxis) confirmed that the incidence of POP was lowered during the second period.. Targeted antibiotic prophylaxis may decrease the rate of POPs after lung resection and improve outcome.
