Mycobacterium abscessus is one of the many species of non-tuberculous mycobacteria. M. abscessus infections are known to be common in patients with cystic fibrosis (CF). Mycobacterium abscessus yields poor cure rates. Liposomal amikacin inhalation (LAI) might be a good alternative for intravenous treatment as the first results with mycobacterium avium treatment yield good results.

The objective of this study is to summarize the clinical data of patients with M.abscessus treated with LAI on compassionate use basis to assess treatment outcomes
