A precise gene-editing tool that reverses single DNA mutations may lead to genetic therapies for people with cystic fibrosis (CF), a study suggests. The study, “Programmable C:G to G:C genome editing with CRISPR-Cas9-directed base excision repair…

Molecular analysis of single cells lining the digestive tract found high CFTR activity — the gene associated with cystic fibrosis (CF) — in some cells in the duodenum, or first part, of the small intestine. A comparison of cells lining the stomach of…

Endoscopic sinus surgery led to better lung function in people with moderate or severe cystic fibrosis (CF) — and some with mild disease — with benefits sustained one year after surgery, a medical records review found. 

For the first time, bacteriophage therapy treated a boy with chronic and antibiotic-resistant Achromobacter bacteria infection following a double lung transplant due to cystic fibrosis (CF), a case study reported.  The study, “…

The Achromobacter bacteria species that is an increasing source of chronic lung infections in people with cystic fibrosis (CF) shows evidence of patient-to-patient transmission and emerging antibiotic resistance, scientists in Denmark report. Their study, “…

Elevated levels of fecal calprotectin protein, a biomarker for intestinal inflammation, was linked to worse gastrointestinal symptoms and quality of life in children with cystic fibrosis (CF), a study reports.  Measuring calprotectin may help clinicians better distinguish the source of gastrointestinal…

People with cystic fibrosis (CF) are more frequently infected with oral Candida fungus and carry a higher number of fungi than healthy individuals, a study has found. All fungal species identified in the study’s CF patients were susceptible to currently available anti-fungal medications. The study, “Oral…

The European Commission has approved Vertex’s Kalydeco (ivacaftor) for the treatment of children and adolescents with cystic fibrosis (CF) who carry the R117H mutation in the…

Children with cystic fibrosis (CF) have an altered intestinal virome, or viral communities, compared to healthy children that may impact growth and intestinal inflammation, a case-control study reported.  The study, ”The intestinal virome in children with…

Kalydeco treatment led to fewer deaths, transplants, hospitalizations, and exacerbations in people with cystic fibrosis (CF) compared to patients who did not receive the therapy, according to a five-year, real-world analysis of patient registries in the U.S. and U.K.  The results of…
