  Introduction: There is a lack of data describing the blood pressure response (BPR) in well-trained individuals. In addition, continuous bio-signal measurements are increasingly investigated to overcome the limitations of intermittent cuff-based BP measurements during exercise testing. Thus, the present study aimed to assess the BPR in well-trained individuals during a cycle ergometer test with a particular focus on the systolic BP (SBP) and to investigate pulse arrival time (PAT) as a continuous surrogate for SBP during exercise testing. Materials and Methods: Eighteen well-trained male cyclists were included (32.4 ± 9.4 years; maximal oxygen uptake 63 ± 10 ml/min/kg) and performed a stepwise lactate threshold test with 5-minute stages, followed by a continuous test to voluntary exhaustion with 1-min increments when cycling on an ergometer. BP was measured with a standard automated exercise BP cuff. PAT was measured continuously with a non-invasive physiological measurements device (IsenseU) and metabolic consumption was measured continuously during both tests. Results: At lactate threshold (281 ± 56 W) and maximal intensity test (403 ± 61 W), SBP increased from resting values of 136 ± 9 mmHg to maximal values of 219 ± 21 mmHg and 231 ± 18 mmHg, respectively. Linear within-participant regression lines between PAT and SBP showed a mean r2 of 0.81 ± 17. Conclusion: In the present study focusing on the BPR in well-trained individuals, we observed a more exaggerated systolic BPR than in comparable recent studies. Future research should follow up on these findings to clarify the clinical implications of the high BPR in well-trained individuals. In addition, PAT showed strong intra-individual associations, indicating potential use as a surrogate SBP measurement during exercise testing.

  Introduction: Noninvasive biomarkers that reflect tubular health and allow early recognition of accelerated graft fibrosis development are warranted. Serum uromodulin (sUmod) and urinary epidermal growth factor (uEGF) originate from kidney tubules and may reflect functional nephron mass. The aim of this study was to investigate the associations between sUmod and uEGF with measured glomerular filtration rate (mGFR) and kidney allograft interstitial fibrosis percentage (IF%) score. Methods: sUmod and uEGF measurements, mGFR by iohexol-clearance and kidney allograft biopsies were obtained from kidney transplant recipients (KTRs) included in the Omega-3 fatty acids in Renal Transplantation (ORENTRA) trial at 8 weeks (baseline) and at 1 year after transplantation (end of study). Associations were analyzed with univariable and multivariable linear regression. Results: Ninety patients at baseline and 48 patients at end of study had complete study variable assessments. uEGF normalized to urinary creatinine (uEGF/Cr) was associated with mGFR both at baseline (standardized β-coefficient [Std. β-coeff] = 0.457 [p = <0.001]) and at end of study (Std. β-coeff = 0.637 [p = <0.001]). sUmod was only associated with mGFR at end of study (Std. β-coeff = 0.443 [p = 0.002]). uEGF/Cr, sUmod, and mGFR were associated with graft IF% score both at baseline (Std. β-coeff = −0.349 [p = 0.001], −0.274 [p = 0.009] and −0.289 [p = 0.006], respectively) and at end of study (Std. β-coeff = −0.365 [p = 0.011], −0.347 [p = 0.016] and −0.405 [p = 0.004], respectively). The results remained largely unchanged in multivariable analysis. Conclusion: uEGF/Cr and sUmod were associated with mGFR and graft IF% score. Our results indicate a possible role of uEGF/Cr and sUmod in the follow-up of KTRs.

  Background. Hypertension in kidney transplant (KTx) recipients is common, affecting both patient and graft survival. Annual data from the Norwegian Renal Registry reveal that <50% of adult (>18 y) KTx recipients reach target blood pressure (BP) ≤130/80 mm Hg. The aim of this study was to identify the determinants of failure to achieve BP control. Methods. In conjunction with the 2018 annual data reporting, additional questions were added for recipients with BP >130/80 mm Hg (treating physician´s target BP for each patient, reasons for not achieving target, method of measurement). Results. Annual forms were received from 98% (3407 of 3486) of KTx recipients, with 1787 (52%) reporting a BP >130/80 mm Hg (“above-target” group). These recipients were older, mostly male, with higher body mass index and serum creatinine levels (P < 0.05) compared with patients with controlled hypertension (“on-target” group). Valid survey answers were available for 84% of the “above-target” group (Survresp) with no significant demographic differences versus nonresponders (Survnonresp). Among Survresp, 32% were under antihypertensive dose titration, whereas dose-limiting side effects were reported in 7%. Target BP was confirmed to 130/80 mm Hg for 60% of Survresp. In recipients for whom the treating physician set target BP >130/80 mm Hg, 51% did not reach these individual targets. The number of antihypertensive drugs was significantly higher in the “above-target” group versus “on-target” group (mean 2.1 ± 1.2 versus 1.8 ± 1.3) and 36% versus 25% used ≥3 antihypertensive drugs (P < 0.05). Automatic attended BP measurement was utilized by 51%. Conclusions. In KTx recipients, a higher BP target achievement seems possible, potentially in the range of 75%-80%.

  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.
