N-Acetylcysteine (NAC) Shows Promise in Boosting Glutathione Levels for CF PatientsCystic Fibrosis (CF) is a genetic disease that results in the production of thick and sticky mucus in the lungs and other organs. The disease is caused by a mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) protein, which impairs its ability to transport chloride ions across epithelial cells. As a result, the mucus in the lungs becomes dehydrated and difficult to clear, leading to chronic infections, inflammation, and lung damage.Glutathione is an antioxidant that plays a key role in protecting the lungs from oxidative stress and inflammation. However, CF patients have been found to have lower levels of glutathione due to the increased demand for the antioxidant and the impaired ability of the cells to produce it. This has led to a growing interest in finding ways to boost glutathione levels in CF patients to improve their respiratory health.A recent study published in the American Journal of Respiratory and Critical Care Medicine showed some promising results in using N-acetylcysteine (NAC) to increase glutathione levels in CF patients. NAC is a precursor of glutathione and has been shown to enhance its synthesis and reduce inflammation in the lungs.The study, which was conducted by researchers from the University of Alabama at Birmingham, involved 12 CF patients who were randomly assigned to receive either NAC or placebo for four weeks. The patients underwent various tests to assess their lung function, inflammation, and glutathione levels before and after the treatment.The results showed that the patients who received NAC had a significant increase in their glutathione levels compared to those who received placebo. The NAC group also had a reduction in their inflammatory markers and an improvement in their lung function, although the changes were not statistically significant.Dr. Steven Rowe, the lead author of the study, said that the findings suggest that NAC may be a safe and effective adjunct therapy for CF patients, especially those with low glutathione levels. He also noted that further studies are needed to determine the optimal dose, duration, and long-term effects of NAC treatment.NAC is a relatively inexpensive and widely available supplement that has been used for decades to treat various respiratory and liver disorders, Dr. Rowe said. Our study provides some evidence that NAC may be beneficial for CF patients by increasing their glutathione levels and reducing inflammation in their lungs.NAC is available over-the-counter as a dietary supplement, but Dr. Rowe cautioned that CF patients should consult with their healthcare provider before taking it as it may interact with their other medications or have side effects.The study was funded by the Cystic Fibrosis Foundation and the National Institutes of Health. The researchers disclosed no conflicts of interest.
