Examining genetics related to insulin and incretins in cystic fibrosis

Evaluation of the Enteroinsular Axis in Cystic Fibrosis

Observational Children's Hospital of Philadelphia · NCT01852448

This study is trying to see how certain genes affect insulin and blood sugar levels in people with cystic fibrosis to better understand diabetes related to the condition.

What this trial studies

This observational study investigates the genetic factors associated with cystic fibrosis related diabetes (CFRD), focusing on the prevalence of specific genetic variants linked to Type 2 Diabetes Mellitus (T2DM). It aims to analyze insulin and incretin secretion in non-diabetic individuals with cystic fibrosis who possess either high-risk or low-risk genetic alleles. By collecting blood or saliva samples from participants aged 2 years and older, the study will assess the relationship between these genetic factors and glucose abnormalities in cystic fibrosis patients. The findings could enhance understanding of CFRD and its implications for patient care.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 2 years and older diagnosed with cystic fibrosis.

Not a fit: Patients with an established diagnosis of non-CFRD, such as Type 1 Diabetes Mellitus, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management strategies for cystic fibrosis related diabetes, potentially enhancing patient outcomes.

How similar studies have performed: Other studies have shown success in exploring genetic factors related to diabetes, but this specific approach in cystic fibrosis is relatively novel.
