Adrenal Disease in Small Mammals.

Area of Science:

• Veterinary Medicine
• Endocrinology
• Small Mammal Research

Background:

• Adrenal gland disease is a rare but significant condition in pet rabbits and rodents.
• Hyperadrenocorticism, characterized by excessive corticosteroid secretion, is particularly noted in guinea pigs and hamsters.
• Clinical signs often mimic those seen in canine dermatologic conditions.

Purpose of the Study:

• To outline the diagnostic approaches for adrenal gland disease in small mammals.
• To detail recommended treatments for hyperadrenocorticism in guinea pigs and hamsters.
• To provide a concise overview of this rare veterinary condition.

Main Methods:

• Diagnosis relies on a combination of clinical signs, diagnostic imaging (e.g., abdominal ultrasound), and blood hormone level determination.
• Specific diagnostic tests include the adrenocorticotrophic hormone stimulation test with salivary cortisol or corticosterone measurement in guinea pigs.
• Treatment strategies involve oral administration of medications such as trilostane or ketoconazole, alongside potential surgical interventions.

Main Results:

• Hyperadrenocorticism is the most common presentation of adrenal disease in guinea pigs and hamsters.
• Dermatologic signs are a key indicator, similar to those observed in dogs.
• Effective treatments include oral trilostane or ketoconazole, with surgery as an alternative.

Conclusions:

• Adrenal gland disease requires a multi-faceted diagnostic approach in small exotic pets.
• Medical management with trilostane or ketoconazole is a primary treatment option.
• Surgical options should also be considered for adrenal disease in guinea pigs and hamsters.
