This is a case report of a 15-month-old boy who developed severe hyponatremic dehydration from COVID-19-associated gastroenteritis. The report describes his clinical presentation, laboratory findings, and successful treatment with fluid and electrolyte repletion.
This case report describes a 15-month-old male presenting to the pediatric emergency department with vomiting, diarrhea, and anuria. He was diagnosed with isolated hyponatremic dehydration secondary to COVID-19-associated gastroenteritis. Key laboratory findings included a serum sodium of 124 mEq/L, anion gap metabolic acidosis, and lymphopenia. The patient was treated with intravenous normal saline boluses and a 24-hour sodium repletion protocol. His sodium normalized to 140 mEq/L by hospital day 3, and diarrhea resolved by hospital day 4. He had no respiratory symptoms and was discharged on hospital day 4. The authors highlight this as a potential nonpulmonary manifestation of pediatric COVID-19, distinct from MIS-C, possibly related to viral enterocyte infection or protein dysregulation.
