Eritropoietina y transfusiones en la anemia del insuficiente renal crónico: visión actualizada / Erytropoietin and tranfusions in anemia of chronic renal failure: update view

ABSTRACT

Aiming to know the factors that influenced the use of erythropoietin (EPO) in chronic hemodialysis patients, we retrospectively studied 82 patients (41 male), of whom 15 received EPO. No differences, between patients receiving or not receiving EPO, were found in age (46.9ñ25 and 57ñ13 years respectively), male/female ratio (9/6 and 32/35 respectively), time on dialysis (36.4ñ25.6 and 36.8ñ31.8 months respectively), dialysis hours (3.19ñ0.6 and 3.33ñ0.39 h respectively) and proportion of diabetics (6.6 and 20.8 percent respectively). Prior to EPO use and compared to untreated patients, treated patients were transfused with a higher frequency (60 vs 22 percent) and with more units/patients/years (0.12 vs 0.08). Hemoglobin levels at the start of the treatment was similar in treated and untreated patients (8.4ñ1.46 vs 8.78ñ1.97 g/dl). Epo was indicated in 11 patients due to general symptomatology associated to anemia and in 4 due to cardiac failure or angina. We conclude that EPO treatment is indicated in approximately 18 percent of patients in dialysis. An adequate dialytic treatment may achieve optimal hemoglobin levels with minimal transfusion requirements and without need of EPO, thus reducing costs
