METABOLIC ALKALOSIS DUE TO THE USE OF AN OLIGOANTIGENIC DIET IN INFANCY

7-month-old boy on an oligoantigenic diet because of multiple food int olerances presented with anorexia, failure to gain weight and severe h ypochloremic metabolic alkalosis with hyperreninemia. Clinical symptom s and biochemical abnormalities disappeared after adequate dietary sup plementation with potassium and sodium chloride. This case emphasizes that minimal daily mineral requirements must be provided in infant die ts, and highlights the risk of nutritional deficiencies inherent in th e prolonged use of oligoantigenic diets not adequately supplemented.
