• Cell-mediated immunity was evaluated in 11 children with diabetes mellitus; six children were evaluated during ketoacidosis and five were evaluated with ketonuria in the absence of acidosis. Five of the six ketoacidotic children had at least one positive delayed-hypersensitivity skin test. Lymphocytes from two ketoacidotic patients were unresponsive to phytohemagglutinin and pokeweed mitogen, and lymphocytes from these two patients plus a third patient were unresponsive to concanavalin A. Lymphocytes from all six patients responded to these three mitogens after one week of therapy.

In the five diabetic children without ketoacidosis, lymphocyte responses were normal to all three mitogens. Similarly, the addition of glucose to normal plasma did not alter the lymphocyte transformations of three healthy nondiabetic controls. These data suggest that cell-mediated immunity may be transiently defective in children with acute diabetic ketoacidosis.
