Nutritional secondary hyperparathyroidism in a domestic feline: Case report

Abstract

Secondary nutritional hyperparathyroidism (HSN) is a metabolic disease characterized by imbalance of the Ca and P, leading to osteopenia. The symptoms are claudication, constipation, lordosis, kyphosis, fractures of long bones and vertebral bodies. The present study reports a case of NSH in a 3-month-old male feline fed with homecare food that was attended at UFPA HOVET presenting claudication that progressed to paraparesis with neurological deficit in pelvic limbs, constipation and urinary retention. It was submitted to hematological, biochemical and radiographic examinations, presenting severe osteopenia with multiple pathological fractures, which related to the clinical data helped to obtain the diagnosis of HSN. The animal was submitted to treatment consisting of confinement, analgesia and alimentary correction and it was obtained satisfactory evolution after 30 days with high medication after 4 months. The literature is very limited as to the clinical data and results of treatment of felines with HSN, although this pathology is becoming increasingly uncommon among felines, contributions are still needed to allow more efficient treatments and more favorable prognoses.
