hormonal analyses indicated ( 1 ) inappropriate early release of glucagon ( 300 pg/ml at 15 minutes ) in patient 1 , ( 2 ) exuberant early release of insulin ( maximum 190 +/- 15 microu/ml ) resulting in rapid decrease in glucose concentration in all patients , ( 3 ) development and/or persistence of hypoglycemia after the decline in circulating insulin to undetectable levels , and ( 4 ) inadequate glucagon response to hypoglycemia resulting in sustained hypoglycemia .
