Increased peripheral venous somatostatin concentration and decreased glucagon response to arginine in patients with insulin dependent diabetes mellitus without residual B-cell function. Increased plasma SRIF in IDDM.
Acta Endocrinol (Copenh). 1985 Aug; 109(4):517-21.AE

Abstract

The glucagon response to insulin hypoglycaemia is frequently reduced in patients with IDDM. In the present study arginine infusion, thought to act directly on the islet cells, was used to stimulate somatostatin (SRIF) and glucagon in IDDM without residual B-cell function. Thirteen IDDM patients' were compared with 13 sex- and age matched normal controls following an arginine infusion. The plasma SRIF concentrations in the 'IDDM group' and normal controls increased from 24.2 +/- 2.5 to 31.1 +/- 3.9 pmol/l (P less than 0.01) and 19.7 +/- 1.7 to 23.9 +/- 3.4 pmol/l respectively after 10 min (P less than 0.01). The plasma glucagon concentrations increased from 27 +/- 4.7 to 176 +/- 23.1 pmol/l (P less than 0.01) and 36 +/- 5.0 to 302 +/- 31.9 pmol/l (P less than 0.01) respectively after 20 min. Thus, in long standing IDDM without residual B-cell function, increased plasma SRIF concentrations are found and the glucagon response to arginine is reduced. The last observation further explains why these patients are especially vulnerable to hypoglycaemia.
