Children generally present in the morning hours after a fast of 10-16 hours. Symptoms typically remit spontaneously by 8-9 years of age. It is felt to be the most common cause of hypoglycemia in childhood and occurs most commonly in children age 19 months to 5 years. Idiopathic ketotic hypoglycemia (IKH) is a physiologic process in which children experience an unusual degree of episodic hypoglycemia after a brief period of caloric deprivation. Final Diagnosis: Idiopathic Ketotic Hypoglycemia The child's symptoms resolve after the administration of glucose in the ED. The hypoglycemia occurs in association with an intercurrent infection or at times of fasting for 12 hours or more. An extensive workup is initiated each time, only to find out that the ultimate cause remains unknown. For the patient in this case, the normal anion gap acidosis helped to exclude several of the early considerations (ie, inborn errors of metabolism) in the ED.ДЄll emergency physicians have had a child present to the ED with ketotic hypoglycemia. It is less helpful if the history does not support many of the causes for a normal anion gap acidosis. The anion gap, especially if elevated, can help direct laboratory evaluation and management. L: Lactic acidosis (hypoxia, sepsis, idiopathic) I: Inborn errors of metabolism, Iron, IsoniazidД¬: Carbonic anhydrase inhibitors (acetazolamide) Causes of Metabolic Acidosis Elevated Anion Gap Acidosis: MUDPILESД: Diabetic ketoacidosis, Diarrheal dehydration The following mnemonics may help emergency physicians direct the care of their patients (Table 2). Organic aciduria: anion gap metabolic acidosis, ketosis, elevated lactate level, neutropenia, thrombocytopeniaДefects in fatty acid metabolism: MCAD, VLCADДЄCTH = adrenocorticotropin hormone GH = growth hormone MCAD = medium-chain acyl-CoA dehydrogenase deficiency VLCAD = very-long-chain acyl-CoA dehydrogenase deficiencyД¬hildren with metabolic acidosis can be classified into 2 groups on the basis of the serum anion gap: a normal anion gap and an elevated anion gap metabolic acidosis. Idiopathic ketotic hypoglycemia: most common form of childhood hypoglycemia presents between age 19 months and 5 years, and remits before age 8-9 yearsДisorders of gluconeogenesis: fructose-1,6-diphosphatase deficiency, galactosemia Hyperinsulinemia: islet cell adenomas, islet cell dysplasia typically presents in the first year of life. Differential Diagnosis of Hypoglycemia Ketotic HypoglycemiaД®ndocrine deficiencies: primary or secondary adrenal insufficiency, pituitary disturbances (ie, GH or ACTH deficiency), and hypothyroidism Urinalysis (for ketones, reducing substances, and urine organic acid analysis)ДЄ good starting point for evaluating hypoglycemia is to determine whether the patient has ketotic or nonketotic hypoglycemia (Table 1). Toxicology studies (ie, salicylates, ethanol, and sulfonylurea) Serum electrolytes (for calculation of anion gap)

Immediate management involves obtaining critical samples and administering parenteral glucose, especially when serum glucose level is в‰¤ 40 mg/dL.Д«lood tests that should be drawn immediately include: In extreme cases, the child may experience seizures and coma. Symptoms include lethargy, irritability, and confusion or behavior that is out of character for the child. The neuroglycopenic stage generally occurs after prolonged hypoglycemia with serum glucose level < 50 mg/dL. These symptoms are generally apparent when the glucose concentration is between 40 and 70 mg/dL. Дuring the autonomic response to hypoglycemia, the child may appear weak, sweating, tachycardic, and tremulous, with feelings of nervousness or hunger. The symptoms of hypoglycemia can be divided into 2 categories: autonomic response and neuroglycopenia. Most agree that a plasma glucose level < 35-45 mg/dL in neonates and a plasma glucose level < 55 mg/dL in children defines hypoglycemia. The precise definition of hypoglycemia in infants and children continues to be controversial. Teaching Points: Hypoglycemia With Non-Anion Gap Acidosis
