Effects of somatostatin analogue SMS 201-995 in non-insulin-dependent diabetes.

The 24-h hormonal and metabolic profiles obtained in five non-insulin-dependent diabetics receiving twice daily s.c. injections of the long-acting somatostatin analogue SMS 201-995 (50 micrograms) have been compared with those obtained following placebo injection. Injections were given 30 min before breakfast and the evening meal. GH secretion was not suppressed by the analogue administered in this manner. Despite suppression of serum insulin levels following breakfast and the evening meal, blood glucose levels were similar during the two study periods with no evidence of worsening in diabetic control. Prolonged suppression of plasma glucagon levels was observed and the nocturnal elevation in serum TSH levels was abolished. Free T4 levels fell significantly following the analogue but total T3 levels were unaffected. Blood alanine levels were elevated throughout the study period following SMS 201-995 but changes in lactate, pyruvate, glycerol and 3-hydroxybutyrate were minor. All five subjects suffered gastrointestinal side-effects. SMS 201-995 (50 micrograms) given twice daily before meals does not cause a deterioration in metabolic control, does not suppress 24-h GH secretion and causes significant side-effects in patients with non-insulin-dependent diabetes mellitus.
