METHODS:We studied hospitalised patients admitted because of acute ulcer bleeding or haemorrhagic gastritis, who had a haematocrit of 27-33% and did not receive blood transfusions.One day after the endoscopic confirmation of cessation of bleeding,they were randomised either to erythropoietin(20 000 IU Epoetin alfa subcutaneously,on days 0,4 and 6)plus iron(100 mg im,on days 1-6,(G_1)or iron only(G_2).Haematocdt was measured on days 0,6,14, 30,45,and 60,respectively. RESULTS:One patient from G_1 and two from G_2 were lost to follow-up.Therefore,14 and 13 patients from G_1 and G_2 respectively were analysed.Demographic characteristics,serum iron,ferritin,total iron binding capacity,reticulocytes,and haernatoait were not significantly different at entry to the study. Median reticulocyte counts were significantly different between groups on day six(G_1:4.0,3.0-6.4 vs G_2:3.5,2.1-4.4%, P=0.03)and median haematocrit on day fourteen [G_1:35.9, 30.7-41.0 vs G_2:32.5,29.5-37.0%(median,range),P=0.04]. CONCLUSION:Erythropoietin administration significantly accelerates correction of anemia after acute ulcer bleeding. The haematocrit gain is equivalent to one unit of transfused blood two weeks after the bleeding episode.展开更多
