|December 1, 1983
Summary
Tropical pancreatic diabetes (TPD) patients show insulin-dependent diabetes with malnutrition but resist ketosis. Their higher C-peptide levels, compared to classical diabetes, likely explain this resistance.
Area of Science:
- Endocrinology
- Metabolic Disorders
- Nutritional Science
Background:
- Tropical pancreatic diabetes (TPD) presents as insulin-dependent diabetes with malnutrition.
- TPD patients do not develop ketosis upon insulin withdrawal, distinguishing them from other diabetes types.
Purpose of the Study:
- To investigate the C-peptide response in TPD patients.
- To compare C-peptide levels in TPD with noninsulin-dependent diabetes (NIDDM), insulin-dependent diabetes (IDDM), and control groups.
Main Methods:
- Assessed fasting and postglucose C-peptide responses.
- Matched participants for body weight across TPD, NIDDM, IDDM, and control groups.
Main Results:
- TPD patients exhibited lower C-peptide concentrations than controls and NIDDM patients.
- C-peptide levels in TPD were significantly higher than in classical IDDM patients.
Conclusions:
- Elevated C-peptide levels in TPD may confer resistance to ketosis.
- This finding provides insight into the pathophysiology of TPD.
