title: Transient insulin resistance following infusion of adrenaline in type 1 (insulin-dependent) diabetes mellitus.
abstract: Insulin resistance was assessed after an intravenous infusion of adrenaline (50 ng.kg-1.min-1) or saline (control study) given between 08.00 and 08.30 hours in nine patients with Type 1 (insulin-dependent) diabetes mellitus. The blood glucose level during a somatostatin (100 micrograms/h)-insulin (0.4 mU.kg-1.min-1)-glucose (4.5 mg.kg-1.min-1)-infusion-test performed between 10.30 and 14.30 hours served as an indicator of the total body insulin resistance. Blood glucose was maintained around 7 mmol/l between 08.00 and 10.30 hours by a constant infusion of regular insulin (0.57 mU.kg-1.min-1) and a variable infusion of a 20% glucose solution. The infusion of adrenaline raised plasma adrenaline to 2.7 +/- 0.3 nmol/l (mean +/- SEM) at the end of the infusion; thereafter it returned to its basal level within 30 min. The plasma levels of free insulin, glucagon, cortisol and growth hormone were similar in the adrenaline and the control studies from 08.00 to 14.30 hours. In comparison with the control study the infusion of adrenaline decreased the need for intravenous glucose significantly over the initial 2 h. Furthermore, during the somatostatin-insulin-glucose infusion test the blood glucose rose significantly (p less than 0.05) over the initial 2 h; thereafter no significant differences between the two studies were seen. It is concluded that a short term infusion of adrenaline, resembling the adrenergic hormone response to hypoglycaemia, induces a diabetogenic effect which subsides within 6 h after omission of the adrenaline infusion.
