title: [Diabetic coma and Wernicke-Korsakoff syndrome. On the clinical significance of acquired thiamine deficiency].
abstract: Following consideration of the nosological role of hyperglycemic states in psychiatry the case report of a fifty-five year-old patient is presented suffering from fatty cell degeneration of the liver and a relapsing pancreatitis due to chronic alcoholism. After a long period of abstinence without previously known diabetes mellitus a sudden ketoacidotic coma developed with maximum serum glucose level of 2020 mg%. Having emerged during coma treatment Wernicke's encephalopathy passed into Korsakoff's syndrome the main features of which remained unchanged for more than one year. In this case thiamine deficiency of different pathogenetical origin is discussed: defective exogeneous availability due to malabsorption; depletion of endogeneous thiamine stores due to enlarged requirements for glucose oxidation during coma therapy; antimetabolic effects to thiamine by nitroimidazole-derivatives administered parenterally.
