Theratyping cystic fibrosis patients to guide elexacaftor/tezacaftor/ivacaftor out-of-label prescription.

Background: Around 20% of people with cystic fibrosis (pwCF) do not have access to the triple combination elexacaftor/tezacaftor/ivacaftor (ETI) in Europe because they do not carry the F508del allele on the CF transmembrane conductance regulator () gene. Considering that pwCF carrying rare variants may benefit from ETI, including variants already validated by the US Food and Drug Administration (FDA), a compassionate use programme was launched in France. PwCF were invited to undergo a nasal brushing to investigate whether the pharmacological rescue of CFTR activity by ETI in human nasal epithelial cell (HNEC) cultures was predictive of the clinical response.

The French compassionate programme of elexacaftor/tezacaftor/ivacaftor in people with cystic fibrosis with advanced lung disease and no F508del variant.

Background: The European Medicines Agency has approved the cystic fibrosis transmembrane conductance regulator (CFTR) modulator combination elexacaftor/tezacaftor/ivacaftor (ETI) for people with cystic fibrosis (CF) carrying at least one F508del variant. The United States Food and Drug Administration (FDA) also approved ETI for people with CF carrying one of 177 rare variants.

Methods: An observational study was conducted to evaluate the effectiveness of ETI in people with CF with advanced lung disease who were not eligible for ETI in Europe.

Comparison of Endoscopic Dilatation and Heller's Myotomy for Treating Esophageal Achalasia in Children: A Multicenter Study.

Objective: To compare the efficacy of, and complications from, the 2 main treatments for achalasia: endoscopic dilatation and surgical cardiomyotomy (Heller's myotomy).

Study Design: We retrospectively collected data on children treated for achalasia over an 11-year period from 8 tertiary pediatric centers. A line of treatment was defined as performing either Heller's myotomy or 1-3 sessions of endoscopy dilatation over 3 months.

Management of Central Venous Catheters in Children and Adults on Home Parenteral Nutrition: A French Survey of Current Practice.

Although central venous catheter (CVC)-related thrombosis (CRT) is a severe complication of home parenteral nutrition (HPN), the amount and quality of data in the diagnosis and management of CRT remain low. We aimed to describe current practices regarding CVC management in French adult and pediatric HPN centers, with a focus on CVC obstruction and CRT. Current practices regarding CVC management in patients on HPN were collected by an online-based cross-sectional survey sent to expert physicians of French HPN centers.
