Die lebensqualität von patienten vor und nach nierentransplantation

The presented study was carried out to differentially assess the quality of life (QOL) of two patient groups with end-stage renal disease (ESRD) with regard to the replacement therapy (dialysis vs. transplantation) and healthy controls. Successfully transplanted patients (n = 149) and patients treated by dialysis (n = 149) on the waiting list for transplantation at the Transplant Center Essen, Germany were enrolled. Additionally, 149 healthy controls were enrolled by an accumulative process starting from employees of the University Hospital Essen. Members of these three groups were strictly matched by age and gender. Medical data were gained from the patient record, QOL was measured by a global inventory, the Munich Quality of Life Dimension List (MLDL), and two specific inventories, the Brief Symptom Inventory (BSI) and the Questionnaire for Social Support - Short Form (K-22). Transplanted patients and healthy controls reported similar QOL, which was significantly higher than in dialysis patients (p < 0.0001). This was particularly true for the physical and the psychological status, but not for the social situation. Both patient groups reported similar social support, which was significantly lower than in controls (p < 0.006). Both ESRD groups described higher satisfaction with social support than the healthy controls (p < 0.0001). Successful kidney transplantation not only improved distinct aspects of QOL, but even put the patients on par with healthy controls regarding physical, psychological and functional QOL. Lower social support and higher satisfaction with social support in both patient groups should be evaluated further. From a clinical viewpoint, the improvement of QOL due to transplantation is impressive, but more attention should be paid to the interpersonal relations of ESRD patients. International multicenter longitudinal studies to investigate QOL in ESRD patients under different treatment modalities are emphasized.
