Improved Clinical Outcome After Treatment of Mycobacterium abscessus Complex Pulmonary Disease in Children With Cystic Fibrosis
BACKGROUND: Mycobacterium abscessus complex pulmonary disease (M. abscessus PD) in cystic fibrosis (CF) is challenging to treat. Current guideline therapeutic regimens involving an intensive phase of intravenous (IV) antibiotics followed by a consolidation phase of inhaled and oral antibiotics are not evidence-based. The objectives of this study were to characterize the clinical outcomes and clearance of Mycobacterium abscessus complex (M. abscessus) from respiratory cultures in children with CF M. abscessus PD.
METHODS: This retrospective longitudinal cohort analysis evaluated the first course of treatment for M. abscessus PD in 33 children in Queensland, Australia between 2001 and 2015. Spirometry and nutritional outcomes 2 years pretreatment and 1 year posttreatment were compared with clearance or relapse/persistence of Mycobacterium abscessus complex from respiratory cultures.
RESULTS: Nine of 18 children who completed therapy, cleared infection. Three of 7 children who completed only intensive therapy cleared sputum compared with 0/8 children who did not. The trajectory of the percent predicted forced expiratory volume in 1 s and age standardized body mass index significantly improved posttreatment in those that cleared sputum (P < 0.0001).
CONCLUSIONS: These results suggest that current treatment recommendations for M. abscessus PD are associated with some success in clearing infection in children with CF and improvement in lung function and body mass index. Clinical trials are required to determine the best treatment approaches.
