Multiple Endocrine Diseases in Cats

Multiple endocrine glandular failure is a recognized syndrome in humans, yet it is an uncommonly recognized phenomenon in veterinary medicine. This is a retrospective study characterizing a population of cats from a university veterinary teaching hospital diagnosed with multiple endocrine disorders. The medical records of 15 cats diagnosed with more than one endocrine disease were reviewed. The most common combination of endocrine disorders noted was hyperthyroidism and diabetes mellitus, making up 11 of 15 cases. Two of 15 cases had concurrent diabetes mellitus and hyperadrenocorticism. One other cat had concurrent diabetes mellitus and central diabetes insipidus, while another was diagnosed with hyperthyroidism and hyperparathyroidism.  A majority of the cases were domestic shorthair cats with the mean age of 10.3 years and a mean of 25.7 months elapsing between the diagnosis of the first and second endocrine disorder. The authors’ results suggest the occurrence of multiple endocrine disorders in cats is uncommon. [VT]
