Gentamicin-associated acute renal failure in the dog

Area of Science:

• Veterinary Medicine
• Nephrology
• Toxicology

Background:

• Gentamicin is a widely used antibiotic in veterinary medicine.
• Nephrotoxicity is a known adverse effect of aminoglycoside antibiotics like gentamicin.
• Understanding the clinical presentation and risk factors for gentamicin-induced acute kidney injury (AKI) is crucial for canine health.

Purpose of the Study:

• To describe the clinical characteristics and outcomes of acute renal failure in dogs treated with gentamicin.
• To identify common clinical and laboratory findings associated with gentamicin-associated AKI.
• To determine potential predisposing factors for the development of gentamicin nephrotoxicity.

Main Methods:

• Retrospective case review of 10 dogs diagnosed with gentamicin-associated acute renal failure.
• Analysis of clinical signs, laboratory data, and patient outcomes.
• Identification of common clinical findings and potential predisposing factors.

Main Results:

• Acute renal failure associated with gentamicin treatment was diagnosed in 10 dogs.
• The condition presented with a poor prognosis and required extended hospitalization.
• Common findings included hypoalbuminemia, potassium homeostasis disorders, proteinuria, hematuria, and cylindruria.
• Fever and dehydration were frequently observed potential predisposing factors.

Conclusions:

• Gentamicin-associated acute renal failure in dogs is a serious condition with significant morbidity.
• Clinical and laboratory abnormalities are characteristic of this nephrotoxicosis.
• Fever and dehydration may increase the risk of developing gentamicin-induced kidney injury.
