Advances in the care of patients with cystic fibrosis have improvedsurvival, and as a result, patients with the disease now oftenlive beyond the third decade.1 In addition, developments inthe understanding of the genetics and molecular mechanisms ofcystic fibrosis have led to new targets for treatment and anincreasingly hopeful outlook. This review summarizes the mechanismsunderlying the disease, the sequelae stemming from the absenceof a functioning cystic fibrosis transmembrane conductance regulator(CFTR), and the therapeutic strategies devised to correct theseabnormalities. Progress in the supportive care of patients withthe disease has been reviewed elsewhere.2,3,4
