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.
