Kidney transplantation does not increase the level of basic hope or life satisfaction compared with hemodialysis in patients with chronic kidney disease.
BACKGROUND
Although renal replacement therapy can lead to improved health, it also can cause emotional disturbances in patients. It is believed that the success of renal replacement therapy hinges not only on medical parameters, but also on psychosocial factors, which is why modern medicine provides an ever-increasing role in the improvement of patients' quality of life.


OBJECTIVE
The purpose of this study was to compare the level of life satisfaction, purpose in life, and basic hope in patients who had received renal replacement due to chronic kidney disease. We also tested whether the specific type of renal replacement therapy and kidney function parameters were influential factors on the above variables.


METHODS
Sixty-one adult patients treated via renal replacement for chronic kidney disease took part in the study. Patients were divided into two groups: 31 hemodialysis patients (15 women and 16 men, ages 23-77 years, mean 51.19 years, SD 14.53 years) and 30 patients who had undergone kidney transplantation (14 women and 16 men, ages 22-69 years, mean 48.40 years, SD 12.64 years). The following research tools were used for analysis: Satisfaction With Life Scale (SWLS), Purpose in Life Test (PIL), and Basic Hope Inventory (BHI-12).


RESULTS
There were no statistical differences in the level of satisfaction with life between hemodialysis patients and postkidney transplant patients. The results for the SWLS obtained from both groups fell within the normal range. The average SWLS for hemodialysis patients remained 20.61, SD = 5.79; for postkidney transplant patients, it was 22.57, SD = 5.16. The PIL level in the group of hemodialysis patients (101.5, SD = 15.64) was significantly lower than in the group of postkidney transplant patients (109.7, SD = 15.54). The average BHI-12 level was similar in both groups. The average BHI-12 result for hemodialysis patients was 29.00 (SD = 5.06), and for postkidney transplant patients 29.93 (SD = 3.55). The correlations between the psychological variables and selected biochemical parameters are worthy of particular attention. Among hemodialysis patients, there was an additional correlation between SWLS and hematocrit; whereas for postkidney transplant patients, there was an additional correlation of PIL and eGFR.


CONCLUSIONS
Our data show that satisfaction with life and basic hope do not increase in patients after renal replacement therapy. The form of renal replacement therapy (hemodialysis or kidney transplantation) does not change the above variables. Patients treated via renal replacement require specialized psychological support to improve the efficacy of renal replacement therapy.
