Abstract

Renal functional deterioration is associated with physical and mental burdens for kidney transplant (KT) and chronic kidney disease (CKD) patients. However, the change in health-related quality of life (HRQOL) over time in KT patients compared to that of native CKD patients has not been evaluated. We addressed this issue using KT patients registered in the KNOW-KT cohort study and patients at CKD stage 1–3 registered in the KNOW-CKD cohort study. HRQOL scores were assessed using the Kidney Disease Quality of Life Short Form at baseline, 2-, and 4-years follow-up in 842 KT patients and at baseline and 5-year follow-up in 1,355 CKD patients. SF-36 scores declined at the 4-year follow-up, whereas CKD-targeted scores showed no change in the KT group. In contrast, CKD-targeted scores as well as SF-36 scores were decreased at the 5-year follow-up in CKD patients. When prognostic factors were analyzed for longitudinal HRQOL data over time, renal functions, diabetes, cardiovascular and cerebrovascular diseases, hemoglobin level, marital status, income, employment, and health care were significant prognostic factors. Furthermore, KT was an independent prognostic factor for better HRQOL. These results highlight that KT can offer a better HRQOL than that of CKD patients, even when renal function is similar.

Highlights

Chronic kidney disease (CKD) patients suffer a worsening quality of life (QOL) along with an increased risk of morbidity and mortality as their renal function deteriorates progressively [1, 2]
When baseline characteristics were compared between included subjects and excluded subjects among kidney transplant (KT) patients with CKD stage 1–3 at baseline, there were no significant differences in the clinical characteristics except for age between the two groups (S1 Table)
The present cohort study demonstrated that KT patients had higher SF-36 scores with respect to both physical and mental QOL than CKD patients at the same CKD stage; they had similar CKD-targeted scores compared to CKD patients with similar renal function

Summary

Introduction

Chronic kidney disease (CKD) patients suffer a worsening quality of life (QOL) along with an increased risk of morbidity and mortality as their renal function deteriorates progressively [1, 2]. CKD patients, including dialysis patients, experience significant physical and mental burdens such as fatigue, pruritus, sleep disturbance, pain, depression, and restless leg syndrome [3,4,5,6], leading to an impaired physical and psycho-social health status [7]. This poor QOL has been strongly associated with adverse clinical outcomes such as increased mortality, morbidity, and frequent hospitalization in CKD patients [1, 8, 9]. Native CKD patients show higher QOL scores than hemodialysis patients but still have lower QOL scores than the general population [15]
