CFTR modulators, a highly effective therapy for cystic fibrosis (CF), do not appear to affect fertility outcomes for men using them, data from surveys of these patients indicate. Miscarriages during pregnancy for a woman whose partner is using modulator therapy and congenital anomalies for the child were not higher than expected, researchers reported.

Note: This story was updated Nov. 9 to note that experiments done with Sionna’s CFTR modulators used a different investigational NBD1 stabilizer than SION-638. SION-638, a first-in-class small molecule that is being developed by Sionna Therapeutics, improved the stability and functionality of the CFTR protein  in the most common…

Exposure to tobacco smoke may reduce the effectiveness of Kalydeco (ivacaftor), a CFTR modulator that is widely approved to treat cystic fibrosis (CF) caused by specific mutations. That’s according to data shared by Gabriela Oates, PhD, at the 2022 North American Cystic Fibrosis Conference, taking place Nov. 3–5…

A novel scoring system may be used to classify the severity of lung disease among children with cystic fibrosis (CF) in their first years of life. Leslie Huang, a medical student at the University of Wisconsin, discussed the system at the 2022 North American Cystic Fibrosis Conference in Philadelphia,…

Women with cystic fibrosis (CF) have different experiences with sexual and reproductive health than their peers without the disease, necessitating special considerations in their care, a new study shows. The study, “Sexual and reproductive health experiences and care of adult women with cystic fibrosis,” was published in the…

The overall protein profile in the airway is altered toward a more pro-inflammatory state in people with cystic fibrosis (CF), and this difference is more pronounced in those with poorer lung function, a new study reports. “Some of these proteins might have value as markers of CF lung disease…

A novel gene-editing treatment platform corrected the mutation that causes cystic fibrosis (CF) in multiple tissues throughout the bodies of mice, according to results of a first-of-its-kind study. “This is the first study looking at treating multiple organs affected by CF with a single gene editing treatment administered intravenously,” Alexandra…

Anemia is common among lung transplant recipients, and people with cystic fibrosis (CF) are at more than four times greater risk of developing anemia post-transplant compared to those with other lung diseases. That’s according to the study “Post-Transplantation Anemia and Risk of Death Following Lung Transplantation,”…

Vitamin C supplements can increase how long vitamin E stays active in the body in people with cystic fibrosis (CF), a small study suggests. “It would seem to be clinically prudent for CF clinicians and nutritionists to recognize the importance of dietary and supplemental vitamin C levels and their…

The average lifespan for someone with cystic fibrosis (CF) is markedly longer in France than in Canada or Australia, a new study reports. Programs that help facilitate access to lung transplants in France may in part explain the difference, according to researchers. “For multiple reasons, which will need to…
