Abstract
Cystic fibrosis is a life-limiting hereditary disorder of the cystic fibrosis transmembrane conductance regulator (CFTR) characterized by recurrent sinopulmonary infections and progressive obstructive lung disease. There are also common manifestations affecting the gastrointestinal, hepatobiliary, endocrine, and reproductive systems. It is most common among non-Hispanic whites of Northern European descent, with a carrier frequency of 1/25. The incidence varies according to population but is estimated at approximately 1 in 2500 to 3500 white newborns. Clinical findings vary according to age, though common features include recurrent sinopulmonary infections and failure to thrive secondary to pancreatic exocrine insufficiency. Therapeutic strategies are focused on preserving lung function, optimizing nutritional status, and managing manifestations of extrapulmonary disease. Astounding progress over the past decade has resulted in mutation-specific pharmacologic interventions, and optimism remains for the future development of medications to treat all patients. Since the initial identification of this autosomal recessive disorder 80 years ago, there has been a dramatic increase in the median age of survival.
