Abstract

AIMS:

To determine whether mild alcohol intoxication (45-50 mg/dl) influences counterregulatory hormone responses to moderate hypoglycaemia (2.8 mmol/l)in patients with Type 1 diabetes.

METHODS:

Seventeen subjects (14 male, age range 21-46 years) with Type 1 diabetes underwent four hyperinsulinaemic glucose clamps: euglycaemia with placebo; euglycaemia with alcohol (0.4 g/kg); hypoglycaemia (2.8 mmol/l for 65 min)with placebo; and hypoglycaemia (2.8 mmol/l for 65 min) with alcohol (0.4 g/kg). Arterialized venous blood samples were taken for measurement of insulin and counterregulatory hormones.

RESULTS:

During hypoglycaemia, peak growth hormone concentrations were significantly lower after alcohol compared with placebo (14.3 +/- 2.9 vs.25.9 +/- 3.4 microg/l,P< 0.001) associated with reduced insulin sensitivity in both hypoglycaemia and euglycaemia studies.

CONCLUSIONS:

We found an attenuated growth hormone response to hypoglycaemia associated with mild alcohol intoxication. Although this may potentially contribute to impaired recovery of glucose after hypoglycaemia in patients with Type 1 diabetes, it appears to be offset by a reduction in insulin action.
