Comparative StudyThe role of transbronchial lung biopsy for the diagnosis of diffuse drug-induced lung disease: a case series of 44 patients.
At present, no studies have evaluated the role of bronchoscopic transbronchial lung biopsy (TBLB) in the diagnosis of diffuse drug-induced lung disease (DILD), and there is no consensus for a definite diagnostic workup approach for this rare clinical entity. The aim of the present study was to evaluate the clinical usefulness of TBLB in diffuse DILD. This study was a retrospective analysis of patients with diffuse DILD, who underwent bronchoscopy. ⋯ No severe complications related to bronchoscopic procedures occurred. In conclusion, TBLB is a safe procedure, and is diagnostically helpful in the majority of cases of patients with diffuse DILD. Histological data obtained by TBLB further corroborate clinical, laboratory, radiologic and BAL results for a definitive diagnosis of diffuse DILD.

Comparative StudyQuantitative analysis of propionibacterial DNA in bronchoalveolar lavage cells from patients with sarcoidosis.
The causes of sarcoidosis are still unknown. Propionibacterial subspieces are thought to be one of the most likely sources of antigens. Here we attempted to measure the amount of propionibacterial DNA in bronchoalveolar lavage (BAL) cell samples from patients with sarcoidosis and other pulmonary diseases. ⋯ The amount of P. acnes DNA in BAL cells from patients with sarcoidosis was significantly higher than that in BAL cells from patients with other pulmonary diseases. P. acnes may be involved in the pathogenesis of sarcoidosis.
