Long-term effects on quality of life in haemodialysis patients of correction of anaemia with erythropoietin

Quality of life assessments were performed in 24 haemodialysispatients (10 males, 14 females, age 45 ±15 years) undergoingrHuEpo treatment. The results in the rHuEpo-treated patientswere compared with those in eight haemodialysis patients noton rHuEpo and with the results of a nationwide study of dialysispatients in Sweden (carried out before rHuEpo was registered).Survey questionnaires (112 items, divided into three dimensions,i.e. physical, social, and emotional wellbeing) were completedbefore treatment (Hb 73± 1.1 g/1), when the target Hbvalue of 10 g/dl was reached (1–7 months) and in 14 patients1 year after correction of the anaemia. Before treatment, therHuEpo group had significantly more complaints about poor appetite,fatigue, and irritability than the controls. After the anaemiawas corrected, the rHuEpo group had significantly improved physicaland emotional wellbeing. The most significant changes occurredin satisfaction with health, physical activities of daily life,and fatigue. Alterations in emotional symptoms, such as depressionand apathy, were less pronounced. Only minor changes were observedin their social wellbeing. One year after correction of theanaemia, the improvements in physical and emotional wellbeingwere still present in the rHuEpo-treated patients. A positiveeffect was also noted on hospitalization rate. Scores for thesubdimensions of satisfaction with health, sexual adjustment,physical symptoms, and emotional wellbeing improved in the rHuEpo-treatedgroup and reached a level that was the same, or even higher,than the scores in the dialysis patients in the nationwide study.In conclusion, the quality of life improved during rHuEpo treatment.The greatest changes were seen in satisfaction with health,physical activity, and emotional wellbeing. The positive effectsobserved after the correction of anaemia persisted after morethan a year on rHuEpo treatment.
