Abstract

Background. Anaemia in diabetes mellitus (DM) and/or chronic renal failure (CRF) may be caused by a decreased production of erythropoietin (EPO), EPO resistance, and by the lysis of the young circulating red blood cells (neocytolysis) induced by subclinical inflammation and low EPO level. Aims of this study were to detect EPO resistance in patients with DM and/or CRF and to prove, that acetylsalicylic acid (ASA) is able to improve the haemopoietic status by decreasing neocytolysis. Methods. In a cross-sectional study, three groups of selected patients (patients with DM; patients with DM+CRF; patients with CRF without DM, n=15 each) and a group of controls (non-diabetic, non- azotemic subjects, n=10) were compared. In the intervention part of the study, the effect of a single dose of 1 gram ASA on neocytolysis was investigated in a subgroup of these patients. Results. Despite the similar EPO level (p=1.000), all three patient groups had lower haemoglobin and haematocrit than control persons (p<0.05 in all cases). Patients with DM+CRF had lower haemoglobin than patients with DM or CRF alone (p<0.05). Single dose of ASA induced a fast increase in serum EPO level, a concomitant rise of the Rtc number and rate, red blood cell count, haematocrit and haemoglobin (p<0.01 for each). These changes were accompanied by a marked decrease in serum lactate dehydrogenase activity (p<0.01). Conclusions. DM and CRF may induce erythropoietin resistance. In these patients, ASA treatment increases serum EPO level. The higher EPO level and the anti-inflammatory effect of ASA may decrease neocytolysis.
