The most common cause is diabetic ketoacidosis (DKA). Organic acidemias (OAs) are inheritable disorders caused by defects in protein metabolism resulting in acid accumulation. Patients with metabolic decompensation usually present with acidosis, with\/without hypoglycemia. Hyperglycemia is a very rare manifestation. At least 16 cases of OAs presenting with hyperglycemia have been reported. Six of the 16 were diagnosed with isolated methylmalonic academia (MMA) and three of the six passed away from late diagnosis.<\/jats:p><jats:p>We describe a 2-year-old Thai girl who presented with hyperglycemia, acidosis and ketosis. She has underlying delayed development, seizures, optic atrophy and poor growth. An initial diagnosis of DKA was made and standard treatment was started. After 4 h of treatment, the patient partially responded to treatment; blood sugar decreased but acidosis and ketonemia persisted. HbA<\/jats:p><jats:p>Inherited metabolic disorders should be included in differential diagnosis in hyperglycemia ketoacidosis patients who respond poorly to standard DKA treatment. Unusual findings, e.g. hyperammonemia, lactic acidosis, pancytopenia, abnormal basal ganglia in MRI or underlying delayed development may indicate underlying OAs. Determining the etiology of hyperglycemic ketoacidosis is important and can lead to good outcomes.<\/jats:p>","DOI":"10.1515\/jpem-2015-0228","type":"journal-article","created":{"date-parts":[[2015,11,18]],"date-time":"2015-11-18T17:00:26Z","timestamp":1447866026000},"source":"Crossref","is-referenced-by-count":15,"title":["Isolated
