A case of transient central diabetes insipidus after aorto-coronary bypass operation

Transient diabetes insipidus after vasopressin discontinuation in cystic fibrosis with septic shock

Central diabetes insipidus (DI) is an uncommon condition caused by reduced or lack of vasopressin secretion from the posterior pituitary gland, typically caused by gland destruction. Several other causes for central DI have also been proposed. Here we present a case of transient central DI after discontinuation of vasopressin used for septic shock without evidence of overt pituitary damage in a cystic fibrosis patient. The serum sodium concentration peaked at 137 mmol/L in the setting of polyuria within 3 days of vasopressin discontinuation without other identified alternative etiologies. Sodium levels and urine output trended down dramatically with desmopressin administration.

Central Diabetes Insipidus in an Off-pump Coronary Artery Bypass Grafting Surgery

Polyuria in perioperative coronary artery bypass grafting (CABG) surgery is common and mostly benign. Diabetes insipidus (DI) post-CABG is however very rare and mostly have been related with use of cardiopulmonary bypass (CPB) pump. The patient recovered completely with transient requirement of exogenous vasopressin. The central DI may be considered as a differential diagnosis in case of polyuria in the perioperative period of CABG surgery.

Deficiency of antidiuretic hormone: a rare cause of massive polyuria after kidney transplantation

A 15-year-old boy, who was diagnosed with Alport syndrome and end-stage renal disease, received a renal transplant from a living-related donor. On postoperative day 1, his daily urine output was 10,000 mL despite normal graft function. His laboratory findings including urine, serum osmolality, and antidiuretic hormone levels showed signs similar to central diabetes insipidus, so he was administered desmopressin acetate nasal spray. After administering the desmopressin, urine specific gravity and osmolality increased abruptly, and daily urine output declined to the normal range. The desmopressin acetate was tapered gradually and discontinued 3 months later. Graft function was good, and urine output was maintained within the normal range without desmopressin 20 months after the transplantation. We present a case of a massive polyuria due to transient deficiency of antidiuretic hormone with the necessity of desmopressin therapy immediately after kidney transplantation in a pediatric patient.

Transient central diabetes insipidus following ischemic stroke

Central Diabetes Insipidus (CDI) following ischemic infarction of the brain has been described as a rare presentation. Posterior pituitary ischemia has also been postulated as a possible cause of idiopathic CDI. We encountered a young male with bilateral extensive ischemic infarction sustained at high altitude, who had transient polyuria due to central diabetes insipidus, requiring desmopressin therapy. DI completely resolved during the course of his neurological recovery.
