Low thiamine levels in children with type 1 diabetes and diabetic ketoacidosis: a pilot study.

Objective: Thiamine deficiency has been documented in adults with diabetes and in a single report of reversible encephalopathy in a child with diabetic ketoacidosis. In children who present with severe diabetic ketoacidosis, one of the most serious complications is cerebral edema of which the primary symptom may be encephalopathy. Thiamine deficiency in other disease states has been clearly linked with acute encephalopathy, but there are no data on thiamine status in children with diabetic ketoacidosis.
