数据说明

Conditions: Cystic Fibrosis. Non-tuberculous mycobacteria (NTM) are important new pathogens in cystic fibrosis, with prevalence estimates ranging from 6% to 13%. The diagnosis of the disease in cystic fibrosis patients is difficult because the infection may remain indolent in some cases without evidence of clinical consequence, while in other patients NTM are associated with significant morbidity and mortality. Treatment requires antibiotic therapy over a prolonged period (at least 12 to 18 months) with several drugs and varies according to NTM and their antibiotic resistance profile. The development of a specialized approach (clinicians / biologists) in the management of this infection, combined with the diagnosis and treatment of NTM infections, in cystic fibrosis patients is a research priority. It is an indispensable long-term strategy for this high-risk population. Two main elements confirm the interest of a prevalence survey of NTM infections in cystic fibrosis (CF) patients: the diagnostic difficulty of “true” infections (as opposed to simple colonizations) to NTM, and the clinical impact on respiratory functions of NTM present in these patients. Two recent contradictory studies on the impact of NTM infections in CF patients have recently been published. The German monocentric study suggests a greater deterioration of respiratory function in CF patients not infected with NTM compared to CF patients infected with NTM. 26 patients were infected with NTM: 14/26 with M. avium complex (MAC), 10/26 with M. abscessus complex and 2/26 with M. gordonae. Only 5 patients out of a dozen positive to M. abscessus and 1 in 14 positive to MAC were treated. Comparatively, the other study found a significant deterioration in respiratory function (maximum expired volume in 1 seconde) of CF patients infected with M. abscessus. This Scandinavian national study reinforced its argument by the fact that an effective treatment made it possible to find changes in maximum expired volume in 1 seconde close to that
