Abstract

BACKGROUND:

Cognitive impairment, anxiety and depression are important problems for patients with chronic kidney failure. Cognitive impairment, anxiety, and depression may be related to various factors, such as complications of hemo/peritoneal dialysis, uremic encephalopathy, psychosocial burden of the disease, and various comorbidities in patients with chronic kidney failure. Successful kidney transplantation (KT) improves kidney, endocrine, metabolic, and vascular systems, mental functions, and the quality of life of the patients.

METHODS:

A total of 181 patients with chronic kidney failure were studied: 54 currently on hemodialysis, 58 on peritoneal dialysis, and 69 with KT. All participants were given a detailed sociodemographic form, including data about the reason of kidney failure, duration of treatment (hemodialysis, peritoneal dialysis, and KT), and comorbid illnesses. Participants were evaluated with the use of the Hospital Anxiety and Depression Scale (HADS) for evaluating depressive and anxiety symptoms and the Brief Cognitive State Examination (BCSE) for detecting possible cognitive impairment.

RESULTS:

Patients with KT had lower levels of anxiety and depression symptoms than patients with hemodialysis and peritoneal dialysis. The KT group scored better than the hemodialysis and peritoneal dialysis groups on the BCSE. The peritoneal dialysis group scored higher on the BCSE than the hemodialysis group. The hemodialysis group scored higher on the HADS than the peritoneal dialysis group.

CONCLUSIONS:

In this study it was found that KT patients have better cognitive and mood regulation outcomes than hemodialysis and peritoneal dialysis patients with chronic kidney failure. With this knowledge we suggest that patients with kidney failure should have KT for having better cognitive functions and mood state as soon as possible.
