We identified 31 patients with human immunodeficiency virus (HIV) infection and lung abscess. All patients had advanced HIV disease, and the mean CD4 cell count was 17/mm3 (range, 2-50/mm3). Twenty-two patients (71%) had previous opportunistic infections, and 24 (77%) had previous pulmonary infections. Symptoms at the time of presentation included fever (90% of patients), cough (87%), dyspnea (35%), pleuritic chest pain (26%), and hemoptysis (10%). The microbiological etiology was established for 28 patients, and the pathogens recovered were bacteria (65%), Pneumocystis carinii (6%), fungi (3%), and mixed microorganisms (16%). The pathogens included Pseudomonas aeruginosa (11), Streptococcus pneumoniae (6), P. carinii (5), Klebsiella pneumoniae (5), Staphylococcus aureus (4), Aspergillus species (3), viridans streptococcus (2), Haemophilus influenzae (1), Streptococcus milleri (1), Proteus mirabilis (1), and Cryptococcus neoformans (1). Mycobacterium tuberculosis was not isolated; two patients for whom a microbiological etiology was not established responded to antituberculous therapy. Patients were treated for 2-12 weeks; 25% of the patients received > 4 weeks of therapy. The outcome was poor: 36% of the patients had recurrences, and 19% died. In patients with AIDS, lung abscess is associated with advanced HIV infection, is due to a broad spectrum of pathogens, responds poorly to antibiotics, and has a poor prognosis.

Bronchiectasis is characterized with irreversible dilatation according to destruction of epithelium, elastic and muscular layer. Most important cause of bronchiectasis is chronic bacterial infections. Pseudomonas aeruginosa colonisation is frequently seen in bronchiectatic patients. We aimed to find out P. aeruginosa colonisation frequency and clinical, radiological and spirometric reflections due to colonisation. We analysed 83 cases retrospectively. Mean age was 58.2 and 54.2% of them were female. Bronchiectasis were localised 19.3% in left lung, 19.3% right and 61.4% bilaterally. 29 (35.8%) normal, 28 (34.6%) obstructive, 7 (8.6%) restrictive, 17 (21%) mixed type disorders are detected in spirometric measures. Sputum culture performed in 50 cases. No microorganism colonisation determined in 30 (60%) cases, P. aeruginosa colonisation 16 (32%), Haemophilus influenzae 2 (4%), 1 (2%) Streptococcus pneumoniae and Proteus mirabilis 1 (2%) cases. P. aeruginosa colonisation determined more frequent in males (p<0.05). No significant correlation detected between colonisation and age or smoking habits (p>0.05). In cases with colonisation; clubbing and hemoptysis were significantly frequent (p<0.05). Only peribronchial thickening was significantly correlated with colonisation in radiological findings (p<0.05). In blood gase analysis PaO2, oxygen saturation were lower and PaCO2 higher in cases colonised with P. aeruginosa but it was not statisticaly significant (p>0.05). Hospitalization rate was higher in P. aeruginosa colonised cases (p>0.05). It is an important problem about mortality because of higher hemoptysis and hospitalisation requirement rate in P. aeruginosa colonised cases.
