title: Effect of a new long-acting somatostatin analogue (SMS 201-995) on glycemic and hormonal profiles in insulin-treated type II diabetic patients.
abstract: Five type II diabetic patients were studied after secondary failure of oral agents, with and without the addition of the new long-acting somatostatin analogue SMS 201-995 to an intermediate-acting insulin regimen. SMS 201-995 was administered twice daily, before breakfast and dinner, as 100 micrograms sc injections, and resulted in a lowering of plasma glucose, as well as of plasma glucagon and serum C-peptide levels. SMS 201-995 abolished postprandial glycemic and xylosemic peaks related to meals and to oral d-xylose when they were taken shortly after the administration of the analogue, while it had no effect on glycemic and xylosemic increments that followed the midday meal. The new somatostatin analogue improves glucose tolerance in type II diabetic patients, both by inhibiting counterregulatory hormones and by delaying and reducing intestinal absorption of nutrients. Its administration could lead to a reduction of daily insulin requirements. Our findings indicate that SMS 201-995 may have a role as an adjunct to insulin in the management of type II diabetic patients after secondary failure of oral agents.
