ABSTRACT
INTRODUCTION: After lung transplantation (LTx), infections caused by multidrug-resistant (MDR) bacteria are frequent and difficult to treat. Some new antibiotics seem to be effective in treating these infections. MATERIAL AND METHODS: We describe our experience in treatment of Klebsiella pneumoniae MDR and Pseudomonas aeruginosa MDR infections with ceftazidime-avibactam (CEF-AVI) and ceftazidime-tazobactam (CEFT-TAZ) in patients who underwent LTx. RESULTS: In 3 patients who underwent double LTx and in 4 patients who underwent single LTx, strains of K. pneumoniae and P. aeruginosa were isolated from bronchoalveolar lavage. All patients showed worsening of respiratory functions, increasing in inflammation indexes, and, in some cases, onset of pulmonary consolidation. P. aeruginosa was treated with CEFT-TAZ for 10 days average (7-15 days) and K. pneumoniae with CEF-AVI for 14 days average (4-24 days). One patient developed a septic state caused by K. pneumoniae, requiring 24 days of therapy. None had shown side effects caused by drugs administration. One patient died after 15 days from lung transplant owing to primary graft dysfunction. CONCLUSIONS: CEF-AVI and CEFT-TAZ seems to be effective in treatment of infections caused by MDR bacteria after lung transplant.

Tracheobronchial foreign body aspiration occurs rarely in adults and may go unrecognized for a long time, but early detection and immediate retrieval of the foreign body are essential to prevent major morbidity. We describe the case of an adult who unusually aspirated part of his dental prosthesis during an attempted strangulation, which was unacknowledged until 6 months later when he was hospitalized with acute respiratory failure and required an emergency surgical tracheotomy. The foreign body was successfully removed via flexible bronchoscopy.
