A diabetic patient presented with weight loss, ketosis, and hyperventilation, thus mimicking the clinical picture of diabetic ketoacidosis. Laboratory investigations revealed alkalemia and a pattern consistent with a triple derangement of acid-base equilibrium: respiratory alkalosis, metabolic acidosis and metabolic alkalosis. High cortisol level suggested a genesis of ketosis different from diabetes mellitus. The patient died suddenly from acute gastrointestinal bleeding. Autopsy showed a carcinoma of the head of the pancreas with secondary portal hypertension and rupture of varices. Pulmonary micrometastases were demonstrated. It is suggested that stress hormones were the main cause of the 'ketoalkalotic' pattern observed.

Abstract
A diabetic patient presented with weight loss, ketosis, and hyperventilation, thus mimicking the clinical picture of diabetic ketoacidosis. Laboratory investigations revealed alkalemia and a pattern consistent with a triple derangement of acid-base equilibrium: respiratory alkalosis, metabolic acidosis and metabolic alkalosis. High cortisol level suggested a genesis of ketosis different from diabetes mellitus. The patient died suddenly from acute gastrointestinal bleeding. Autopsy showed a carcinoma of the head of the pancreas with secondary portal hypertension and rupture of varices. Pulmonary micrometastases were demonstrated. It is suggested that stress hormones were the main cause of the 'ketoalkalotic' pattern observed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
