To the editor: Drs. Sherman, Pfefferbaum, and Brown (Ann Intern Med 73:259-261, 1970) reported a case of hypoparathyroidism occurring in a patient with longstanding iron storage disease in whom an abnormal glucose tolerance test (GTT) was an incidental finding. The authors attributed this mild diabetes mellitus to either his genetic predistposition or to his iron overload. It seems to me that the hypocalcemie hypoparathyroid state per se should also have been considered as a possible cause for the abnormal GTT.
