Abstract:
Objective To study the effect of recombinant human erythropoietin (rHuEPO) on in aged patients undergoing maintenance hemodialysis. Methods Blood pressure and its mechanism 52 elderly patients undergoing maintenance hemodialysis divided into two groups, HBP group (23 cases with hypertension) and NBP group(29 cases without hypertension). The plasma vasoactive substances were measured by radioimmunological methods. Fifteen cases in NBP group as EPO group were given a bolus of venous injection of rHuEPO (3 000 IU), others in NBP group (14 cases) were injected 0.9% saline as control group. The plasma vasoactive substances were assayed before and 1, 3, 6, 9, 12, 18, 24, 30, 44 hours after therapy with or without rHuEPO. Results (1) The plasma dopamine (DA) in HBP group were significantly higher than that of NBP group. (2) Endothelin levels increased transiently but DA levels increased steadily in EPO group. Conclusions The study suggests that the effect of rHuEPO induced on hypertension in the elderly patients undergoing maintenance hemodialysis is associated with the increasing plasma DA.
