THU147 Peritoneal Dialysis To Improve Hyperglycemic Hyperosmolar State In Child With Renal Failure

Disclosure: P. Choudhari: None. S. Mootha: None. Background: Hyperglycemic hyperosmolar state (HHS) without ketosis is rare in children. While the crux of management of HHS is extensive hydration followed by insulin, this management can be difficult for children with kidney failure. Clinical Case: A 6-year-old female with complex medical history including Jeune syndrome (asphyxiating thoracic dystrophy), end stage renal disease status post kidney transplant, currently with rejection, now on peritoneal dialysis (PD), and history of steroid induced hyperglycemia was admitted for altered mental status. Several days prior to the current admission, she was admitted for an upper respiratory infection and found to have hyponatremia, which improved with fluid restriction and sodium supplementation. Subsequent worsening of hyponatremia led to adjustments in her PD to include higher amounts of dextrose in the dialysate (1.5% to 2.5%). At the current admission, she was found to have a blood glucose of 2096 mg/dL, uncorrected sodium of 121 mg/dL, corrected to 153 mg/dL, serum osmolality of 406 mOsm/kg, and hemoglobin A1c of 11.3%. She had mild acidemia and beta-hydroxybutyrate of 0.5 mmol/L. She was transferred to the Pediatric Intensive Care Unit (PICU) and intubated given her waxing and waning mental status and complex history. Since she was anuric, fluid resuscitation was carefully managed. She received a total of 14 mL/kg normal saline boluses, which lowered blood glucose by about 240 mg/dL. Multidisciplinary conversations between PICU, Endocrinology, and Nephrology culminated with a plan to attempt to slowly reduce blood glucose levels via PD prior to using regular insulin infusion. 24-hour PD was restarted with lower dextrose in the dialysate (1.5%). Due to persistent hypotension, she required norepinephrine infusion and stress dose hydrocortisone. With PD, blood glucose levels decreased by 20-30 mL/kg/hr in the first day. Regular insulin infusion was started, while continuing 24-hour PD, after blood glucoses stagnated at 1400-1500 mg/dL. After 4-5 days of PD and insulin infusion, the child’s blood glucoses decreased to 300-400 mg/dL. After tolerating her g-tube feeds, she was transitioned to an insulin pump as she was requiring high doses of insulin (1.8 units/kg/hr). Conclusion: We present a child with complex medical history, including history of steroid induced hyperglycemia, end stage renal disease status post renal transplant, anuria, currently on PD, who developed hyperglycemic hyperosmolar state (HHS). PD helped to lower her significant hyperglycemia, initially without insulin. There are few case reports on the use of PD or hemodialysis to improve hyperglycemia or hypernatremia in children with renal failure. This case demonstrates dialysis can be an effective strategy to attempt for children in a hyperosmolar state in whom aggressive fluid management can be detrimental.
