Exocrine pancreatic function in juvenile-onset diabetes mellitus
Diabetic patients show reduced exocrine pancreatic function, with decreased bicarbonate, trypsin, and amylase output. This impairment is more severe and prevalent in juvenile-onset diabetes, correlating with disease duration.
Area of Science:
- Endocrinology
- Gastroenterology
- Metabolic disorders
Background:
- Diabetes mellitus is a complex metabolic disorder with various systemic complications.
- Exocrine pancreatic dysfunction can occur in diabetic patients, but its prevalence and characteristics require further elucidation.
Purpose of the Study:
- To investigate exocrine pancreatic function in patients with different types of diabetes mellitus.
- To compare pancreatic function between diabetic patients and non-diabetic controls.
Main Methods:
- Studied exocrine pancreatic function by measuring bicarbonate, trypsin, and amylase outputs.
- Utilized intravenous secretin and cholecystokinin-pancreozymin (CCK-PZ) stimulation.
- Included patients with juvenile-onset diabetes, maturity-onset diabetes, and diabetes secondary to chronic pancreatitis, alongside non-diabetic controls.
Main Results:
- Diabetic patients exhibited significantly reduced outputs of bicarbonate, trypsin, and amylase compared to controls.
- Eighty percent of juvenile-onset diabetics showed reduced exocrine pancreatic secretory capacity.
- The severity of exocrine pancreatic dysfunction in juvenile-onset diabetes correlated with the duration of the disease.
Conclusions:
- Exocrine pancreatic function is impaired in patients with diabetes mellitus.
- The degree of exocrine pancreatic dysfunction is linked to diabetes duration, particularly in juvenile-onset cases.
- Clinicians should consider reduced exocrine pancreatic capacity when assessing diabetic patients.

Cells and Secretions of the Pancreas
Exocrine function is carried out by acinar cells, organized into clusters known as acini. These cells contribute to digestion by releasing substantial quantities of enzyme-rich, alkaline digestive juices.
Concurrently, the dispersed clusters of endocrine cells throughout the...

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
Pancreatic Juice and Secretion
When acidic chyme from the stomach enters the duodenum, it triggers the release of secretin, a hormone that prompts pancreatic juice secretion. After a fatty meal, cholecystokinin, another hormone, stimulates gallbladder contraction and enhances enzyme-rich...
