[Cystic fibrosis in adults].

In the last two decades the life expectancy of patients with cystic fibrosis (CF) has improved enormously: it is now estimated at around 30 years, but some patients reach an older age and one third of all patients with CF currently reach adulthood. Once considered a pediatric disease, CF now is a disease of adults too. As a consequence, internists must be highly knowledgeable about all the clinical patterns of this multifarious disease, must be better qualified to recognize its complications and must be highly trained to treat them.
