Determination of the Predictive Factors in the Reversibility or the Aggravation in the Disorders of the Glucose Metabolism in Cystic Fibrosis Patients

Determination of the Predictive Factors in the Reversibility or the Aggravation in the Disorders of the Glucose Metabolism in Cystic Fibrosis Patients (Study DIAMUCO)

For some years, the investigators observe an increase of the arisen of diabetes in cystic fibrosis patients However, this diabetes may be reversible. The investigators speak about " Cystic fibrosis related diabetes.". The objective of this project, is to know better what facilitates the appearance and the reversibility of the diabetes, such as the genetic mutations, the respiratory state and the lung infections. Theses knowledges should allow to adapt the screening of diabetes, and its treatment, for the patients affected by cystic fibrosis.

Inclusion Criteria:
