  Data on sleep quality in renal transplanted (RTX) patients are scarce, and longitudinal studies are lacking. The purpose of this study was to assess the prevalence of sleep complaints in RTX patients and identify variables associated with improvement in sleep quality. In a longitudinal study, 301 dialysis patients were followed for up to 5.5 years, during which time 142 were transplanted. Out of the transplanted patients, a total of 110 were eligible for inclusion. Sleep quality and depression were assessed with the validated questionnaires Pittsburgh Sleep Quality Index (PSQI) and Beck Depression Inventory (BDI), and data were collected during dialysis and after RTX. Based on PSQI scores, 59% were characterized as poor sleepers after RTX compared to 75% when in dialysis (P = 0.016). A total of 46% experienced a clinical relevant improvement in overall sleep quality, while 21% experienced a clinical relevant deterioration. In multivariable analyses, clinical meaningful change in sleep quality was not associated with either depressive symptoms assessed with BDI or other clinical variables. Sleep quality improved after RTX in nearly half of the patients, but poor sleep quality was prevalent in RTX patients. Therefore, sleep quality should routinely be assessed in RTX patients.

  Context Patients on dialysis experience multiple concurrent and often related symptoms defined as symptom clusters. Renal transplantation (RTX) is thought to reduce symptom experience and improve health-related quality of life. No longitudinal study has assessed symptoms and symptom clusters in patients in the transition from dialysis to RTX. Objectives We aimed to assess changes in symptom prevalence, identify symptom clusters after RTX, and evaluate the effect of the treatment conversion on predefined symptom clusters. Methods A cohort of patients on chronic dialysis (n = 110) was followed prospectively with measurements of health-related quality of life using the Kidney Disease and Quality of Life-Short Form (KDQOL-SF) during dialysis (baseline) and after subsequent RTX. Predefined symptom clusters based on 11 symptoms listed in KDQOL-SF were previously generated using principal component analysis with varimax rotation, that is, uremic (nausea, lack of appetite, dizziness, feeling squeezed out, shortness of breath, and chest pain), neuromuscular (numbness, sore muscle, and cramps), and skin (itching and dry skin) clusters. Stratified analyses were undertaken to identify characteristics associated with change in the symptom clusters after RTX. Cohen's d was used as effect size. Results Of the 110 patients, mean age was 51.3 ± 14.4 years, and 66% were males. After RTX, the estimated glomerular filtration rate was 54 (interquartile range [IQR] 45–72) mL/minute/1.73 m2. Median follow-up time from assessments during dialysis was 55 (IQR 50–59) months, and follow-up time after RTX was 41 (IQR 34–51) months. The total symptom score improved (73 ± 16 vs. 82 ± 15, P = 0.001, and Cohen's d = 0.6), and the number of symptoms was reduced (6.5 ± 2.6 vs. 4.7 ± 3.0, P = 0.001). Seven symptoms improved statistically after RTX, but only two with Cohen's d > 0.5 (itching and cramps). The scores of the predefined symptom clusters improved after RTX: uremic (82 ± 16 vs. 85 ± 17, P = 0.008, and Cohen's d = 0.2), neuromuscular (66 ± 24 vs. 79 ± 18, P = 0.001, and Cohen's d = 0.6), and skin cluster (62 ± 27 vs. 78 ± 22, P = 0.001, and Cohen's d = 0.6). Symptom clusters could not be generated after RTX. Conclusion Although symptoms and symptom clusters were reduced after RTX, the clinical relevance of the reductions was ambiguous. Symptom clusters could not be generated after RTX, suggesting that use of the KDQOL-SF may not be optimal to assess symptoms in RTX patients.

  Abstract Background. Renal dysfunction is considered a confounding variable in the interpretation of B-type natriuretic peptides (BNPs) and their amino-terminal fragments (NT-ProBNP) in patients with heart failure (HF). Our aim was to investigate the prognostic utility of BNPs and NT-proBNP in HF outpatients with renal dysfunction, and compare the prognostic significance of the corresponding BNP/NT-ProBNP levels in patients with and without renal dysfunction. Methods. A total of 2076 patients from 13 HF clinics in the Norwegian Heart Failure Registry were investigated. The BNP/NT-ProBNP levels were categorized centre-wise into four groups using the quartile limits found in patients with preserved renal function. Patients with renal dysfunction, i.e. glomerular filtration rate (GFR)≤ 60 mL/min/1.73 m2, were then assigned to BNP groups 1–4 centre-wise according to their level of natriuretic peptides. Results. Renal dysfunction was present in 37.5% of the patients, of whom the majority (59.1%)had levels of natriuretic peptide in the highest BNP group. Patients with renal dysfunction and BNP levels in the lower three BNP groups had similar 2-year survival as patients without renal dysfunction and comparable BNP levels [crude hazard ratio (HR) 1.25, 95% CI 0.82–1.89,P =0.302, multiple adjusted HR 0.85, 95% CI 0.54– 1.33, P =0.457]. Beyond 2 years of follow-up,renal dysfunction predicted all-cause mortality irrespective of the level of natriuretic peptides at the start of follow-up. Conclusion. In HF outpatients, the BNP/NT-ProBNP level predicted 2-year mortality irrespective of renal function and provided important prognostic information on patients with renal dysfunction.
