Primary Hyperaldosteronism in Cats: An Underdiagnosed Disorder

Area of Science:

• Veterinary Medicine
• Endocrinology

Background:

• Primary hyperaldosteronism, or Conn's syndrome, is the most prevalent adrenocortical condition in felines.
• This endocrine disorder is frequently underdiagnosed in cats, leading to inadequate patient care.
• Many cats with hypertension or hypokalemia receive only symptomatic treatment, masking the root cause.

Purpose of the Study:

• To increase awareness of feline primary hyperaldosteronism among general practitioners.
• To provide a comprehensive overview of the (patho)physiology, clinical signs, diagnostics, and therapeutics for this condition in cats.

Main Methods:

• Review of current literature on feline primary hyperaldosteronism.
• Synthesis of information regarding pathophysiology, clinical presentation, diagnostic workup, and treatment strategies.

Main Results:

• Primary hyperaldosteronism is underdiagnosed, often presenting as hypertension and/or hypokalemia.
• A systematic diagnostic approach is necessary to identify the condition accurately.
• Appropriate treatment can significantly improve outcomes for affected cats.

Conclusions:

• General practitioners must be vigilant for primary hyperaldosteronism in cats presenting with suggestive clinical signs.
• Accurate diagnosis and targeted treatment are essential to avoid undertreatment and improve feline health.
• This article serves as a guide to understanding and managing feline Conn's syndrome.
