Transient Fanconi syndrome in Quarter horses.

Abstract: Two Quarter horses with weight loss had glucosuria, euglycemia, and a mild metabolic acidosis suggesting a proximal renal tubular defect. Further testing revealed transient generalized aminoaciduria, lactic aciduria, and glucosuria, indicating Fanconi syndrome. Both horses recovered with supportive therapy. This is the first report of acquired Fanconi syndrome in horses. Deux chevaux Quarter horse ayant subi une perte de poids étaient atteints de glucosurie, d’euglycémie et d’une acidose métabolique légère suggérant un défaut tubulaire rénal proximal. De nouveaux tests ont révélé une amino-acidurie, une acidurie lactique et une euglycémie généralisée transitoire, indicatif du syndrome de Fanconi. Les deux chevaux se sont rétablis avec une thérapie de soutien. Il s’agit du premier rapport du syndrome de Fanconi acquis chez les chevaux.(Traduit par Isabelle Vallières).

This research describes the first documented cases of acquired Fanconi syndrome, a kidney disorder, in Quarter horses. The disorder was transient and the horses recovered after receiving supportive therapy.

Background of the Research

  • The research focuses on two Quarter horses that had experienced weight loss and undergone extensive medical tests.
  • The initial symptoms suggested a problem with their kidneys, specifically a defect in their proximal renal tubules – a part of the kidney essential for the absorption and secretion of various molecules.
  • More extensive tests revealed that the horses had temporary generalised aminoaciduria, glucosuria and lactic aciduria, conditions associated with Fanconi syndrome.

Fanconi Syndrome

  • Fanconi syndrome is a condition that affects the kidney’s ability to absorb and process certain molecules and ions. This can lead to abnormal excretion of glucose, amino acids, bicarbonate ions, water, and other substances in the urine. The condition can be either genetic or acquired through exposure to certain toxins, drugs, or diseases.
  • In this study, the horses exhibited symptoms typical of Fanconi syndrome – glucosuria, aminoaciduria, and lactic aciduria. Glucosuria refers to glucose in the urine, aminoaciduria involves amino acids being present in the urine and lactic aciduria indicates lactic acid in the urine.

Findings and Recovery

  • The study found that the two Quarter horses had an acquired form of Fanconi syndrome, not a genetic form.
  • The syndrome was transient, meaning that it was temporary. The horses’ conditions improved with the help of supportive therapy.
  • This study is significant because it’s the first time that Fanconi syndrome has been documented to occur in horses. This addition to medical literature can aid future diagnosis and treatment of this syndrome in equine patients.
