Somatostatin (SRIF) given intravenously, either as a single bolus or as a 2 hr infusion caused a significant prolongation of partial thromboplastin time (PTT) and depressed platelet counts and platelet aggregation in the rat. Following daily injections of protamin-zinc SRIF for 2 weeks the platelet count returned to normal, PTT remained prolonged and platelet aggregation was enhanced. The doses of SRIF used in this work were adequate to suppress the secretion of insulin and glucagon by the isolated pancreatic islets of treated animals.

The effect of short- and long-term somatostatin (GIF) administration on haemostatic function in man was investigated. The dosage programme applied in this study was 250 mug GIF as a bolus injection and 250 mug GIF/h by way of infusion. In five healthy volunteers a short-term (3h) treatment resulted in a statistically significant drop of platelet count and impairment of platelet aggregation at the end of infusion. However, these changes were within the physiologically normal range and disappeared after two hours on all subjects. Other parameters such as bleeding time, thromboplastin and partial thromboplastin time, fibrinogen, fibrin/fibrinogen split products, plasma factor XIII, ethanol gelation test were not affected. In two patients with gastric haemorrhage and persistent amylasaemia a 67 or 120-h treatment induced no remarkable haemostatic defect. By contrast, peptic ulcer bleeding in one patient stopped 60 min after starting the GIF infusion. These studies indicated that somatostatin administration in man at the dosage programme used neither results in clinical evidence indicating bleeding tendency nor does it influence laboratory parameters in an apparent way.

Preliminary evidence has suggested that somatostatin might interfere with platelet function in the baboon. Because this agent is currently being administered experimentally to human beings, we studied its effect on coagulation and platelet function in man. In five subjects, a four-hour infusion of somatostatin (500 micrograms per hour) had no definite effect on platelet count, leukocyte count, hematocrit, platelet adhesiveness and aggregation, bleeding time, partial thromboplastin time, prothrombin time, and fibrinogen levels. A similar infusion for 18 hours in three subjects was likewise without effect. These studies indicate that somatostatin does not affect coagulation and platelet function in man and that its prolonged administration lacks ostensible toxicity.
