Hypoadrenocorticism-like syndrome in a cat with Tritrichomonas foetus infection: a case report

Abstract

A reduced sodium: potassium ratio is an uncommon finding in cats, and is typically associated with conditions such as hypoadrenocorticism, severe renal and cardiovascular diseases, cavitary effusion and certain non-parasitic gastrointestinal diseases. This report describes a case of a 1-year-old female Maine Coon cat showing severe hyperkalaemia and hyponatraemia, associated with gastrointestinal signs and Tritrichomonas foetus infection. Adrenocorticotropic Hormone (ACTH) stimulation testing excluded hypoadrenocorticism. Supportive care combined with antiprotozoal treatment using ronidazole led to long-term clinical resolution and normalisation of the electrolyte abnormalities.
