Abstract
ABSTRACT: Primary adipsia is a rare condition in which there is failure in the activation threshold of the hypothalamic osmoreceptors, leading to osmolality imbalance. Here, we reported the case of a Pit Bull dog with an altered level of consciousness (started after weaning) and adipsia. There was an increase in plasma osmolality (444 mOsm/kg), sodium (223.7 mg/dL), and chlorine (173 mg/dL) levels. Based on the suspicion of primary adipsia, water was administered via a nasogastric tube, with clinical improvement. The owner was instructed to supply water with food. Eight months after discharge, the dog returned with parvovirus and died. In the anatomopathological examination, no structural changes were observed in the central nervous system. To our knowledge, this is the first report of hypernatremia due to adipsia in a Pit Bull dog, showing that this is a differential diagnosis that should be considered in this breed.
