Summary
Veterinary diabetes mellitus (DM) classifications align with human types, with dogs often presenting as type I (IDDM) or secondary (S), cats as type I (IDDM), and horses as type S. Obesity is linked to impaired glucose tolerance and type II (NIDDM) in dogs.
Area of Science:
- Veterinary Medicine
- Endocrinology
- Comparative Pathology
Background:
- Human diabetes mellitus (DM) nomenclature has been revised and widely accepted.
- Established classifications include type I (IDDM), type II (NIDDM), secondary (S), impaired glucose tolerance (IGT), gestational diabetes, and previous abnormality of glucose tolerance (PrevAGT).
Purpose of the Study:
- To review and compare the classifications and common causes of diabetes mellitus in dogs, cats, and horses based on existing literature.
- To correlate animal diabetes types with human classifications and identify associated conditions like obesity.
Main Methods:
- Literature review of documented cases of diabetes mellitus in dogs, cats, and horses.
- Analysis of reported classifications, etiologies, and associated conditions.
Main Results:
- Over half of diabetic dogs are type I (IDDM), with significant proportions of type S and type II (NIDDM). Obesity is common in IGT and NIDDM.
- Diabetic cats typically exhibit type I (IDDM) due to pancreatic islet destruction and amyloidosis.
- Secondary diabetes in dogs is often caused by pancreatic damage, hyperadrenocorticism, or hypersomatotropism. Progestogen therapy is a frequent cause in cats.
- Equine diabetes is type S, usually secondary to pituitary tumors or chronic pancreatitis.
Conclusions:
- Veterinary diabetes mellitus exhibits classifications analogous to human DM, with distinct common etiologies across species.
- Understanding these comparative classifications aids in diagnosis and management of diabetes in companion animals and horses.
