[Alcoholic ketoacidosis--3 episodes in one patient]

3 episodes of alcoholic ketoacidosis were observed in one female patient over a period of 19 months. The clinical picture consisted of vomiting, dehydration, hyperventilation and abdominal pain. Predominant laboratory findings were acidosis (pH less than 7) and hyperglycaemia, with blood glucose values of 354, 330 and 147 mg/dl. This disorder is an important cause of metabolic acidosis, but especially in the German literature there are only rare reports on this issue. The picture of ketoacidosis in mostly chronically malnourished alcoholics reflects not only the complex abnormalities of acid-base balance caused by excessive cumulation of ketoacids, but also the related severe depletion of electrolytes and extracellular volume. Adequate acute therapy (as for diabetic ketoacidosis) and thorough follow-up treatment of any concurrent conditions result in rapid reversal of the syndrome in most cases. Since there are few reports of repeated episodes in one patient, an overview of this disorder is presented concerning management and differential diagnosis of the basis of our case report.
