Failure of somatostatin to correct manifest diabetic ketoacidosis.
Juvenile diabetic patients were studied 60-72 hours after insulin withdrawal when moderate ketoacidosis had developed. Somatostatin infusion for 4 hours in five patients resulted in almost complete suppression of plasma pancreatic glucagon and growth hormone, a fall in plasma-cyclic-adenosine-monophosphate (A.M.P.) concentrations, and a large fall in plasma-glucose concentration. After infusion plasma concentrations of these substances rose again. Blood-ketone-bodies, plasma-free-fatty-acids (F.F.A.), and plasma glycerol concentrations, however, did not decrease appreciably with somatostatin administration. In three patients 2 to 3 h somatostatin infusions were twice superimposed upon a continuous 9-5 h insulin infusion (1 unit/h). An insulin effect was noticeable within 30 minutes, with pronounced falls in the concentrations of plasma glucose, pancreatic glucagon, F.F.A., and blood-ketone-bodies. There was no significant change in these patterns when somatostatin was administered or withdrawn. These results do not indicate that somatostatin infusion would be useful in the treatment of manifest diabetic ketoacidosis.
