A clinical case of transient diabetes insipidus with high spinal trauma

Abstract

BACKGROUND: Diabetes insipidus is characterized by the kidneys inability to absorb water and concentrate urine, which is based on a defect in the synthesis or secretion of vasopressin and is manifested by severe thirst and excretion of large volumes of diluted urine. Data on diabetes insipidus in adults with isolated spinal injury are presented in single works of foreign authors, and no domestic and foreign publications have focused on diabetes insipidus in children. Available publications are descriptions and evaluations of the diseases clinical picture according to clinical and laboratory abnormalities and analyzed therapy in the postoperative period. CLINICAL CASE: This study presents a clinical case of transient diabetes insipidus in a 12-year-old patient with high-level spinal cord injury after shrapnel and explosive trauma. A detailed description of the clinical picture is provided. DISCUSSION: Polyuria, polydipsia, and low urine density were noted on day 14 after surgical correction and stabilization of post-traumatic spinal deformity with spinal cord rupture at the CVICVII level. The condition was considered a transient diabetes insipidus. Clinical and laboratory recovery was achieved on day 12 after surgery thanks to treatment by desmopressin. CONCLUSIONS: This clinical case presents that diabetes insipidus may develop in pediatric patients with isolated spinal injury. Given the insufficient understanding of the causes of this rare disease, differential diagnosis is necessary for pediatric patients with high-level spinal cord injuries associated with polyuria and low urine density. Moreover, treatment with desmopressin should be prescribed appropriately.
