Effects of new and emerging therapies on gastrointestinal outcomes in cystic fibrosis.
Several new therapeutic modalities have recently become available to be used in patients with cystic fibrosis such as potentiators, modulators, and probiotics. Although the effects on pulmonary function have been well documented, gastrointestinal outcomes have been addressed only rarely.. Both the potentiator (ivacaftor) and the potentiator/modulator combination (ivacaftor/lumacaftor) that are currently on the market have a positive effect on BMI. Young patients (2-5 years of age) with a gating mutation may show improvement of exocrine pancreatic function on ivacaftor. In this specific patient population this agent also seems to improve intestinal pH and reflux. The effect of these medications on other gastrointestinal outcomes, such as intestinal inflammation and cystic fibrosis liver disease, has not been described so far. Furthermore, the results of several trials suggest that probiotics might reduce intestinal inflammation. Finally, organoids might be used to predict in vitro the clinical effect of potentiators and modulators.. The effect of new interventions on the gastrointestinal outcomes studied so far is favourable. Future studies should address the effect on other gastrointestinal parameters.

Impact of CFTR modulation with Ivacaftor on Gut Microbiota and Intestinal Inflammation.
Cystic fibrosis (CF) is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Next to progressive airway disease, CF is also associated with intestinal inflammation and dysbiosis. Ivacaftor, a CFTR potentiator, has improved pulmonary and nutritional status but its effects on the intestinal microbiota and inflammation are unclear. Hence, we assessed the changes on the intestinal microbial communities (16S rRNA variable 3 gene region) and inflammatory markers (calprotectin and M2-pyruvate kinase [M2-PK]) in 16 CF individuals (8 children and 8 adults) before and after (median 6.1 months) ivacaftor. Stool calprotectin significantly decreased following ivacaftor (median [IQR]: 154.4 [102.1-284.2] vs. 87.5 [19.5-190.2] mg/kg, Pā=ā0.03). There was a significant increase in Akkermansia with ivacaftor. Increased abundance of Akkermansia was associated with normal stool M2-PK concentrations, and decreased abundances of Enterobacteriaceae correlated with decreased stool calprotectin concentrations. In summary, changes in the gut microbiome and decrease in intestinal inflammation was associated with Ivacaftor treatment among individuals with CF carrying at least one gating CFTR mutation. Thus, CFTR-modifying therapy may adequately improve the aberrant pathophysiology and milieu of the CF gut to favor a more healthy microbiota, which in turn reduces intestinal inflammation.
