[Pulmonary Disease caused by less common Nontuberculous Mycobacteria - New international guidelines].

The spectrum of pulmonary disease caused by nontuberculous mycobateria (NTM) is diverse, and each species requires species-specific therapy. With the new ATS/ERS/ESCMID/IDSA guideline on the management of pulmonary disease caused by NTMs covering only the most common pathogens, namely M. avium complex (MAC), M. kansasii, M. xenopi, and M. abscessus, it was necessary to write treatment recommendations for pulmonary disease caused by rarer NTM species that were still represented in the old 2007 guideline.The panel of guideline committee members from the ATS, ERS, ESCMID, and IDSA- therefore, independently of the professional societies, again conducted systematic literature reviews to develop evidence-based recommendations for the treatment of lung disease caused by seven additional organisms: M. chelonae, M. fortuitum, M. genavense, M. gordonae, M. malmoense, M. simiae, and M. szulgai. A German summary of these international recommendations is presented here.
