Cystic fibrosis- related diabetes (CFRD) is a diment form of diabetetes that develops in people living with cystic fibrosis.

CFRD is one of the mogt comon comorbidities in older children and cidults with cystic fibrosis. Agretately 20% of estacents and 40- 50% of adutts with cystic fibrosis develop CFRD.

Thee Importance of Accurate Diagnosis

Misdiagsing CFRD as type 1 or type 2 can lead to inapplicate treament plans that harm overall health. For example, putting a person with CFRD on a calorie-restricted diet (typical for type 2) can worsen malnutrion and akcelerate lung decline.

Autoantibody testing can help applide type 1, while C atlantide levels and insulin resistance markers diferentate type 2. In CFRD, C- peptide is typically low but not absent, and autoantibodies are negative.

Te Role of CFTR Modulator Therapies

Te advent of CFTR modulator terapies - such as ivacaftor, lumacaftor, tezacaftor, and elexacaftor - has transformed the landrie of cystic fibrosis care.

Screening and Monitoring Recommendations
