[Cystic fibrosis: home treatment]

The authors describe the rules of monitoring and treatment of cystic fibrosis at home. These rules apply to the respiratory component of the disease, which is often insidious and yet clinically predominant and has repercussions on the patient's nutritional status. They also apply to the hepatic and diabetic components, both of which must be recognized and treated. Most of the treatment can be carried out at home with obvious social, epidemiological, psychological and financial benefits.
