Effects of Ivacaftor in cystic fibrosis patients carrying the G551D mutation with severe lung disease.
The development of ivacaftor represents a significant advance in therapeutics for patients with cystic fibrosis (CF) who carry the G551D mutation. Patients with an FEV1 < 40% predicted represent a considerable proportion of eligible patients but were excluded from phase 3 clinical trials, and the effectiveness of the drug in this population is, therefore, unknown. ⋯ Ivacaftor was clinically effective in patients with CF who carry the G551D mutation and have severe pulmonary disease. The reductions in treatment requirements were clinically and statistically significant and have not been described in less severe populations.

American College of Chest Physicians' (CHEST) new Living Guidelines Model will not only provide clinicians with guidance based on the most clinically relevant and current science but will also allow expert-informed guidance to fill in any gaps in the existing evidence. These guidance documents will be updated, as necessary, using one or more of three processes: (1) evidence-based guidelines, (2) trustworthy consensus statements, and (3) a hybrid of the other two. The new Living Guidelines Model will be more sustainable and will encourage maintenance of current and targeted recommendations and suggestions. ⋯ These reliable statements of guidance for health-care providers and patients are based on a rigorous methodology and transparency of process.
