Metabolic Disorders Associated with Renal Disease in Horses.

The research article presents an overview on the metabolic disorders related to renal disease in horses, further addressing their pathophysiology, clinical signs, and respective treatments.

Understanding Metabolic Disorders linked to Renal Disease

• The article initiates its discussion by exploring the metabolic disorders that are associated with renal or kidney disease in horses. These disorders primarily consist of problems that alter the body metabolism of horses and disrupt their bodily functions. This body metabolism is often linked to the kidneys which, when diseased or damaged, can lead to metabolic dysfunction.

Pathophysiology, Clinical Signs and Treatment of Hyperchloremic Metabolic Acidosis associated with Renal Tubular Acidosis

• The research shifts its focus towards hyperchloremic metabolic acidosis, which is a subset of disorders that is associated with renal tubular acidosis. This specific disorder is marked by high levels of chloride ions in the blood, leading to acidification or a drop in blood pH. The researchers discuss the physiological origin of this problem, presenting potential clinical signs applicable to its detection, and deliberating possible treatment options to mitigate its negative effects on horses.

Uremic and Hyponatremic Encephalopathies

• Subsequently, the authors talk about conditions affecting the central nervous system of horses, mainly uremic encephalopathy and hyponatremic encephalopathy, that are secondary to renal diseases. The first is a type of brain dysfunction caused by kidney failure resulting in the buildup of waste products in the blood (uremia). The second is a brain dysfunction caused by abnormally low sodium levels in the blood (hyponatremia). Both these disorders can have severe effects on a horse’s central nervous system, disturbing its behavior, responses, and overall health.

Calcium and Phosphorus Homeostasis and the Syndrome of Calcinosis and Calciphylaxis

• Lastly, the study brings attention to calcium and phosphorus homeostasis in the horses’ body. These minerals are crucial for numerous biological functions, and their balance (homeostasis) is of utmost importance. The discussion accentuates on a recently detected syndrome of calcinosis and calciphylaxis, the cause for which remains uncertain. Calcinosis typically refers to the condition marked by abnormal calcium deposits in the body’s soft tissues, while calciphylaxis is an uncommon, yet serious disease characterized by calcification of blood vessels leading to skin necrosis and potentially, other fatal complications.
