Environmental Reservoirs of Non-tuberculous Mycobacteria in Cystic Fibrosis Households: A Case-control Study of Exposure Risk at Home

This multicenter, non-interventional case-control study investigates whether household environmental reservoirs, particularly water systems, are associated with non-tuberculous mycobacterial (NTM) infections in people with cystic fibrosis. Environmental samples from the homes of CF patients with and without NTM infection will be analyzed and genetically compared with available clinical isolates, alongside assessment of environmental risk factors, to improve understanding of exposure pathways and inform future prevention strategies.

Prevalence of Exercise-induced Ventilatory Limitation and Associated Factors in Patients With Cystic Fibrosis Receiving Elexacaftor-Tezacaftor-Ivacaftor

Cystic fibrosis is a genetic disorder affecting the entire body and associated with respiratory exacerbations, impaired quality of life and reduced life expectancy. The therapeutic management of cystic fibrosis has been profoundly changed by the recent arrival of a combination of highly effective cystic fibrosis transmembrane conductance regulator (CFTR) modulators, Elexacaftor-Tezacaftor-Ivacaftor (ETI), which improve quality of life, respiratory function and reducing the number of exacerbations. The impact of these treatments on exercise adaptation has not been clearly identified. The main objective is to estimate the prevalence of ventilatory reserve amputation during submaximal exercise testing assessed by the 6-minute walk test (6MWT) in patients with cystic fibrosis treated with ETIs.
