Are patients with Hirschsprung's disease prediabetic?

Area of Science:

• Gastroenterology
• Endocrinology
• Metabolic Research

Background:

• Hirschsprung's disease (HD) is typically viewed as a distal gastrointestinal condition.
• Emerging evidence suggests autonomic dysfunction and upper gastrointestinal dysmotility in HD patients.
• This points to potential systemic involvement beyond the distal colon and rectum.

Purpose of the Study:

• To investigate potential endocrine involvement in surgically treated adult Hirschsprung's disease patients.
• To assess fasting and postprandial glucose and insulin levels in HD patients compared to healthy controls.
• To determine if HD is associated with altered glucose-insulin homeostasis.

Main Methods:

• A cohort of 16 surgically treated adult HD patients and 17 healthy controls participated.
• Subjects underwent an overnight fast followed by ingestion of a standardized liquid caloric meal.
• Blood samples were collected serially to measure glucose and insulin concentrations.

Main Results:

• Adult HD patients exhibited significantly higher fasting glucose and insulin levels compared to controls.
• Postprandial insulin peaks were significantly elevated in the HD group.
• Glucose peak concentrations tended to be higher in HD patients, suggesting impaired glucose metabolism.

Conclusions:

• Adults with a history of Hirschsprung's disease demonstrate impaired glucose and insulin homeostasis.
• Findings indicate a mild degree of insulin resistance in this patient population.
• This metabolic profile suggests an increased susceptibility to non-insulin-dependent diabetes mellitus.
