Abstract
The routine use of recombinant erythropoiesis-stimulating agents (ESA) over the past three decades has enabled the partial correction of anaemia in most patients with end-stage renal disease (ESRD). Since ESA use frequently leads to iron deficiency, almost all ESA-treated haemodialysis patients worldwide receive intravenous iron (IV) to ensure sufficient available iron during ESA therapy. Patients with inflammatory bowel disease (IBD) are also often treated with IV iron preparations, as anaemia is common in IBD. Over the past few years, liver magnetic resonance imaging (MRI) has become the gold standard method for non-invasive diagnosis and follow-up of iron overload diseases. Studies using MRI to quantify liver iron concentration in ESRD have shown a link between high infused iron dose and risk of haemosiderosis in dialysis patients. In September 2017, the Pharmacovigilance Committee (PRAC) of the European Medicines Agency (EMA) considered convergent publications over the last few years on iatrogenic haemosiderosis in dialysis patients and requested that companies holding marketing authorization for iron products should investigate the risk of iron overload, particularly in patients with end-stage renal disease on dialysis and, by analogy, patients with IBD. We present a narrative review of data supporting the views and decision of the EMA, and then give our expert opinion on this controversial field of anaemia therapeutics.

Abstract
OBJECTIVE Thoracic empyema in uremic patients on maintenance hemodialysis is a challenging situation. The clinical characteristics are rarely reported, and the surgical outcomes remain unclear. We report our experience with video-assisted thoracoscopic surgery in these patients during 10-year period of time. METHODS Between 2005 and 2015, we retrospectively reviewed the clinical characteristics, bacteriological studies, and thoracoscopic surgical results of 23 empyema patients undergoing maintenance hemodialysis. RESULTS The mean patient age was 67.1 ± 12.9 years. All patients had additional preexisting systemic diseases. The mean duration of hemodialysis was 34.7 ± 25.8 months. The infections causing empyema were pneumonia in 11 (47.8%), blood stream infection in 8 (34.8%), and uremic pleuritis in 4 (17.4%). Among the 22 identified microorganisms, the most common pathogen was methicillin-resistant Staphylococcus aureus (31.8%). After thoracoscopic surgery, 8 patients (34.8%) required additional procedures for complications, including 2 patients who required repeated thoracoscopy for hemothorax and 6 (26.1%) patients who required open drainage for residual empyema. The mean hospital stay was 62.4 days, and 6 patients (26.1%) died in the hospital. Univariate and multivariate analyses revealed that maintenance hemodialysis longer than 5 years was a significant factor associated with in-hospital mortality (odds ratio: 14.8, 95% confidence interval 1.5-151.6; p < 0.0001). CONCLUSION While surgical management of thoracic empyema in uremic patients undergoing maintenance hemodialysis is associated with high rates of complication and mortality, thoracoscopic surgery is feasible, especially for patients undergoing hemodialysis for less than 5 years.

Abstract
Chronic kidney disease (CKD) is a global health problem and is independently associated with increased risk for cardiovascular disease (CVD). The presence and severity of CKD is strongly related to the progression of coronary atherosclerosis, ventricular hypertrophy, myocardial fibrosis, valvular calcification, and cardiac conduction system abnormalities. Echocardiography plays a major role in the assessment of structural and functional cardiac abnormalities in CKD including abnormal left-ventricular (LV) geometry, LV diastolic dysfunction, valvular disease, and left atrial dilatation, which are very frequently present especially in patients with end-stage renal disease.

Abstract
BACKGROUND Studies of the timing of end-stage renal disease (ESRD) have primarily defined "early" versus "late" initiation of dialysis using estimated glomerular filtration rate (eGFR)-based criteria. Our objective was to determine the theoretical time that could be spent in chronic kidney disease (CKD) stage 5 prior to reaching a conservative eGFR threshold of 5 mL/min/1.73 m2 compared to the actual time spent in CKD stage 5 by risk factors of interest. METHODS Eight-hundred and seventy Chronic Renal Insufficiency Cohort participants with CKD stage 5 who started renal replacement therapy (RRT) were included for retrospective study. We used mixed models to estimate the person-specific trajectory of renal function. We then used these individual trajectories to estimate the amount of time that would be spent in CKD stage 5 (between eGFR of 15 and 5 mL/min/1.73 m2) and compared this estimate to the actual time spent in CKD stage 5 prior to ESRD (between eGFR of 15 mL/min/1.73 m2 and ESRD). RESULTS We found the median observed time between eGFR of 15 mL/min/1.73 m2 to RRT was 9.6 months, but the median predicted time between eGFR of 15 mL/min/1.73 m2 to eGFR of 5 mL/min/1.73 m2 was 17.7 months. Some of the largest differences between the predicted and actual amount of time spent in CKD stage 5 were noted among those with systolic blood pressure <140 mm Hg (9.7 months longer predicted compared to actual), proteinuria <1 g/g (9.1 months), and serum albumin ≥3.5 g/dL (9.0 months). CONCLUSION We found marked differences between the actual and predicted time spent in CKD stage 5 based on risk factors of interest. We believe that placing timing of dialysis initiation in the perspective of time is novel and may identify subgroups of patients who may derive particular benefit from a more concerted effort to delay RRT.

Abstract
AIM Children and adolescents with end-stage renal disease face a high morbidity and mortality. Palliative care provides a multidisciplinary approach to reduce disease burden and improve quality of life. This study evaluated concepts and current structures of palliative care from the perspective of a multidisciplinary paediatric nephrology team including physicians, nurses and psychosocial health professionals. METHODS Evaluation was done by an online survey sent to the members of the German Society of Nephrology and to the nurse managers of German paediatric dialysis centres between April 9, 2018 and May 31, 2018. RESULTS Out of the 52 respondents, 54% were physicians, 21% nurses and 25% psychosocial health professionals. The quality of actual palliative care service was rated as moderate (3.3 on a scale from one to six). Specialised palliative care teams (54%) and the caring paediatric nephrologist (50%) were considered as primarily responsible for palliative care. Two thirds wished for training in palliative care. In only 15% of the respondents' centres, palliative care specialisation existed. CONCLUSION Palliative care structures in paediatric nephrology were not sufficient in the view of the multidisciplinary healthcare team. Therefore, efforts should be taken to integrate palliative care into the routine treatment of children and adolescents with chronic kidney diseases.

Abstract
BACKGROUND The main study aim was to track infections, evaluate performance, and identify opportunities for improved practice since infections, especially those associated with multidrug-resistant organisms, are the second most common cause of death among end-stage renal disease patients. METHODS This study describes the establishment of baseline dialysis event surveillance at a large dialysis center. Every month, the dialysis center staff reported the total number of maintenance hemodialysis patients to the department of infection control and hospital epidemiology. The surveillance system for dialysis events included monthly monitoring of hemodialysis patients in outpatient settings for positive blood cultures, intravenous antimicrobial initiation, and local vascular access infections. RESULTS We calculated the pooled mean rates of positive blood cultures, intravenous antimicrobial initiation, and local vascular access infections during the period from June 1, 2014 to September 30, 2017. Results indicated more dialysis events were attributed to the CVC than any other dialysis vascular access. Regardless of vascular access type, intravenous antimicrobial initiation was the most commonly reported dialysis-associated event. CONCLUSIONS Dialysis events surveillance can be used to produce a decrease in both morbidity and mortality rates in hemodialysis patients.

Abstract
OBJECTIVE To examine concordance and tensions in values among stakeholder groups across the shared decision making process for end-stage renal disease patients treated with hemodialysis. METHODS A thematic analysis of transcripts from three stakeholder groups: hemodialysis patients (2 groups, n = 17), nephrologists (1 group, n = 9), and non-physician providers (dietitians, social workers, and registered nurses) (1 group, n = 8). A framework of decision-making components (communication, information, decision, behavior, and outcome) guided analysis of values within and across groups. RESULTS Shared values included communication that informed patients and involved family; information about function, trajectory, life context, and patient experience; behavior to manage diet; and outcomes of function, safety, and survival. Identified thematic tensions in patient-provider values were: personalized vs. routinized communication; shared vs. separate information; managed vs. adherent behavior; and participating vs. protected outcome. Patient behavior emerged as a contested area of control. CONCLUSION Emphasizing shared values and bridging values conflicts may ease tensions surrounding self-care behavior by facilitating discussions about diet, medications, and consistent dialyzing. PRACTICE IMPLICATIONS More individualized information needs to be delivered to patients in a personalized communication approach that can still be achieved within a busy dialysis clinic setting.

Abstract
BACKGROUND/AIMS Patients with chronic kidney disease (CKD) have been found to show markedly increased rates of end-stage renal disease, major adverse cardiovascular and cerebrovascular events (MACCEs), and mortality. Therefore, new biomarkers are required for the early detection of such clinical outcomes in patients with CKD. We aimed to determine whether the level of circulating renalase was associated with CKD progression, MACCEs, and all-cause mortality, using data from a prospective randomized controlled study, Kremezin STudy Against Renal disease progression in Korea (K-STAR; NCT00860431). METHODS A retrospective analysis of the K-STAR data was performed including 383 patients with CKD (mean age, 56.4 years; male/female, 252/131). We measured circulating renalase levels and examined the effects of these levels on clinical outcomes. RESULTS The mean level of serum renalase was 75.8 ± 34.8 μg/mL. In the multivariable analysis, lower hemoglobin levels, higher serum creatinine levels, and diabetes mellitus were significantly associated with a higher renalase levels. Over the course of a mean follow-up period of 56 months, 25 deaths and 61 MACCEs occurred. Among 322 patients in whom these outcomes were assessed, 137 adverse renal outcomes occurred after a mean follow-up period of 27.8 months. Each 10- μg/mL increase in serum renalase was associated with significantly greater hazards of all-cause mortality and adverse renal outcomes (hazard ratio [HR] = 1.112, p = 0.049; HR = 1.052, p = 0.045). However, serum renalase level was not associated with the rate of MACCEs in patients with CKD. CONCLUSION Our results indicated that circulating renalase might be a predictor of mortality and adverse renal outcomes in patients with CKD.

Abstract
BACKGROUND Iatrogenic induced hypothyroidism had been described in newborns and more particularly in preterm infants after cutaneous or intravenous exposure to iodine. CASE-DIAGNOSIS : We reported a new risk of iodine intoxication with the cases of two newborns who developed hypothyroidism after intra vesical iodine injection during a cystography, which was performed to confirm antenatal diagnosis of posterior urethral valves (PUV). The newborns both developed transient hypothyroidism due to an iodine overdose. CONCLUSIONS These two observations suggest that voiding cystourethrography (VCUG) should be carefully considered in newborns with severe uropathy, particularly in the case of renal insufficiency. If indicated, thyroid function should be monitored in the following weeks, and in case of hypothyroidism treatment should be started.

Abstract
AIMS/HYPOTHESIS Activation of the receptor for AGE (RAGE) has been shown to be associated with diabetic nephropathy. The soluble isoform of RAGE (sRAGE) is considered to function as a decoy receptor for RAGE ligands and thereby protects against diabetic complications. A possible association between sRAGE and diabetic nephropathy is still, however, controversial and a more comprehensive analysis of sRAGE with respect to diabetic nephropathy in type 1 diabetes is therefore warranted. METHODS sRAGE was measured in baseline serum samples from 3647 participants with type 1 diabetes from the nationwide multicentre Finnish Diabetic Nephropathy (FinnDiane) Study. Associations between sRAGE and diabetic nephropathy, as well as sRAGE and diabetic nephropathy progression, were evaluated by regression, competing risks and receiver operating characteristic curve analyses. The non-synonymous SNP rs2070600 (G82S) was used to test causality in the Mendelian randomisation analysis. RESULTS Baseline sRAGE concentrations were highest in participants with diabetic nephropathy, compared with participants with a normal AER or those with microalbuminuria. Baseline sRAGE was associated with progression from macroalbuminuria to end-stage renal disease (ESRD) in the competing risks analyses, but this association disappeared when eGFR was entered into the model. The SNP rs2070600 was strongly associated with sRAGE concentrations and with progression from macroalbuminuria to ESRD. However, Mendelian randomisation analysis did not support a causal role for sRAGE in progression to ESRD. CONCLUSIONS/INTERPRETATION sRAGE is associated with progression from macroalbuminuria to ESRD, but does not add predictive value on top of conventional risk factors. Although sRAGE is a biomarker of diabetic nephropathy, in light of the Mendelian randomisation analysis it does not seem to be causally related to progression from macroalbuminuria to ESRD.

Abstract
BACKGROUND AND OBJECTIVES Cardiovascular (CV) mortality represents the leading cause of death in patients with end-stage renal disease (ESRD). Efficient screening is required to detect CV disease at an early stage, but the best diagnostic work-up is uncertain. The aim of this study was to identify electrocardiographic parameters in dialysis patients associated with an increased frequency of CV events. METHODS A 12-lead electrocardiogram was performed in 139 patients who were on the renal transplant waiting list and who subsequently received a kidney transplant. CV events were analyzed from the day of listing for kidney transplantation until 1 year after renal transplantation. RESULTS Multivariate Cox regression analysis showed that an elevated T:R ratio in anterior and inferior leads was independently associated with CV events (T:R ratio of anterior leads hazard ratio [HR] 1.32 [95% CI 1.09-1.59; p = 0.004] and inferior leads HR 2.15 [95% CI 1.23-3.77; p = 0.008]). In particular, a T:R ratio in inferior leads exceeding 0.6 was associated with CV events in a Kaplan-Meier analysis. CONCLUSIONS Taken together, we found an increased T:R ratio in ESRD patients to be a predictive marker for CV events.

Abstract
Background Bile acids are important metabolites of intestinal microbiota, which have profound effects on host health. However, whether metabolism of bile acids is involved in the metabolic complications of end-stage renal disease (ESRD), and the effects of bile acids on the prognosis of ESRD remain obscure. Therefore, this study investigated the relationship between altered bile acid profile and the prognosis of ESRD patients. Methods A targeted metabolomics approach based on ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was used to determine the changes in serum bile acids between ESRD patients (n = 77) and healthy controls (n = 30). Univariate and multivariate statistical analyses were performed to screen the differential proportions of bile acids between the two groups. Results Six differentially expressed bile acids were identified as potential biomarkers for differentiating ESRD patients from healthy subjects. The decreased concentrations of chenodeoxycholic acid, deoxycholic acid and cholic acid were significantly associated with dyslipidemia in ESRD patients. Subgroup analyses revealed that the significantly increased concentrations of taurocholic acid, taurochenodeoxycholic acid, taurohyocholic acid and tauro α-muricholic acid were correlated to the poor prognosis of ESRD patients. Conclusions The serum bile acid profile of ESRD patients differed significantly from that of healthy controls. In addition, the altered serum bile acid profile might contribute to the poor prognosis and metabolic complications of ESRD patients.

Abstract
ANCA-associated vasculitis (AAV) may lead to irreversible organ damage, particularly end-stage renal disease (ESRD) requiring dialysis. The chances of renal recovery diminish with prolonged dialysis. We describe a case of a 32-year-old woman admitted for pulmonary infiltrates and acute renal failure. Autoimmune workup revealed an elevated titer of proteinase 3-antineutrophil cytoplasmic antibody (PR3-ANCA). The diagnosis of granulomatosis with polyangiitis (GPA) was confirmed by renal biopsy. The patient received induction therapy with IV rituximab (375 mg/m2 per week for 4 weeks) along with systemic high-dose IV corticosteroids and one pulse of IV cyclophosphamide (1000 mg). Rapid deterioration of her kidney function led to pulmonary edema requiring intensive care (ICU) hospitalization. Dialysis and plasmapheresis were initiated. Significant clinical improvement ensued, but the patient remained dialysis dependent. No immunosuppressive maintenance therapy other than prednisone was given. Chronic dialysis was discontinued successfully after eight months. At a follow-up of 30 months since her hospitalization, the patient is in complete remission without relapses. We suggest that rituximab induction without maintenance therapy for GPA ESRD may be adequate.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection is a documented risk factor for chronic kidney disease (CKD) and progression to end-stage renal disease (ESRD). However, to date there are no reports on the long-term hard endpoints (ESRD and death) of anti-HCV therapy [interferon-based therapy (IBT) or new direct-acting antivirals] in CKD patients. Direct-acting antivirals are not available in Taiwan's single-payer national health insurance database currently released for research. Therefore, we hypothesized that a retrospective analysis of the long-term outcomes of IBT in CKD patients will serve as a proxy for direct-acting antivirals to increase our understanding of progression to ESRD following HCV infection. AIM To evaluate the long-term outcomes (ESRD and death) of anti-HCV therapy, especially IBT, in HCV-infected patients with stage 1-5 CKD. METHODS We analyzed 93894 Taiwanese adults diagnosed with CKD and without HBV infection. Of these, 4.9% were infected with HCV. Of the 4582 HCV-infected CKD patients, 482 (10.5%) received IBT (treated cohort). They were matched 1:4 with 1928 untreated HCV-infected CKD patients (untreated cohort) by propensity scores and year, which further matched 1:2 by propensity scores with 3856 CKD patients without HCV infection (uninfected cohort). All participants were followed until the occurrence of ESRD, death, or the end of 2012. The association between HCV infection, IBT use, and risks of ESRD and death was analyzed using competing risk analysis. RESULTS Taking the uninfected cohort as a reference, the adjusted hazard ratios for ESRD, after adjusting for competing mortality, were 0.34 (0.14-0.84, P = 0.019) and 1.28 (1.03-1.60, P = 0.029) in the treated and untreated cohorts, respectively. The treated cohort had a 29% (0.54-0.92, P = 0.011) decrease in mortality compared to the untreated cohort, in which the mortality was 31% (1.18-1.45, P < 0.001) higher than in the uninfected cohort. The reduced risks of ESRD (0.14, 0.03-0.58, P = 0.007) and death (0.57, 0.41-0.79, P = 0.001) were greatest in HCV-infected CKD patients who received at least 4 mo of IBT, which accounted for 74% of the treated cohort. CONCLUSION Adequate anti-HCV therapy in CKD patients improves long-term renal and patient survival.

Abstract
Prior studies have shown that beginning hemodialysis (HD) with a hemodialysis catheter (HC) is associated with worse mortality than with an arteriovenous fistula (AVF) or arteriovenous graft (AVG). We hypothesized that transplant waitlisting would modify the effect of HD access on mortality, given waitlist candidates' more robust health status. Using the US Renal Data System, we studied patients with incident ESRD who initiated HD between 2010 and 2015 with an AVF, AVG, or HC. We used Cox regression including an interaction term for HD access and waitlist status. There were 587,607 patients that initiated HD, of whom 82,379 (14.0%) were waitlisted for transplantation. Only 26,264 (4.5%) were transplanted. Among patients not listed, those with an AVF had a 34% lower mortality compared to HC [adjusted hazard ratio (aHR) 0.66, 95% confidence interval (CI) 0.65-0.67] while those with an AVG had a 21% lower mortality compared to HC (aHR 0.79, 95% CI 0.77-0.81). Transplant waitlisting attenuated the association between hemodialysis access type and mortality (interaction p < 0.001 for both AVF and AVG vs. HC). Among patients on the waitlist, those with an AVF had a 12% lower mortality compared to HC (aHR 0.88, 95% CI 0.84-0.93), while those with an AVG had no difference in mortality (aHR 0.95, 95% CI 0.84-1.08). While all patients benefit from AVF or AVG over HC, the benefit was attenuated in waitlisted patients. Efforts to improve health status and access to healthcare for non-waitlisted ESRD patients might decrease HD-associated mortality and improve rates of AVF and AVG placement.

World Neurosurg 2019; 129:e452-e457. [PMID: 31150864 DOI: 10.1016/j.wneu.2019.05.182] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2019] [Revised: 05/20/2019] [Accepted: 05/22/2019] [Indexed: 11/28/2022]
Abstract
OBJECTIVE To present a preliminary experience of perioperative management for patients with spinal tuberculosis (STB) and end-stage renal disease (ESRD) and discuss strategic factors that should be considered. METHODS A retrospective study of 6 patients with STB and ESRD who underwent spine surgeries in our hospital from January 2010 to May 2017 was carried out. Medical records were reviewed for clinical manifestations, laboratory examinations, radiologic findings, perioperative management, clinical outcomes, and complications. RESULTS Except for 1 patient who died of cardiac arrest 5 days after surgery, this case series was followed with a mean follow-up period of 17.0 months (range, 9-23). There were no patients reporting major side effects related to an adjusted antituberculosis chemotherapy regimen. Postoperatively, surgical incision healed primarily, whereas delirium and pneumonia were noted in 2 patients. At final follow-ups, solid bony fusion was achieved in 4 patients, whereas fusion was indefinite in the patient who underwent surgery at L3/4 level. Visual analogue scale score improved from preoperative 5.2 ± 0.37 to 2.6 ± 0.55 at the final follow-ups. CONCLUSIONS Perioperative management of patients with STB and ESRD is a complicated issue, with multiple factors to be considered. Spinal surgery can achieve acceptable outcomes in these patients if meticulous management is performed.

Abstract
BACKGROUND Data on clinical outcome after drug-eluting stent (DES) vs. bare-metal stent (BMS) implantation in patients with end-stage renal disease (ESRD) under hemodialysis are limited and controversial.Methods and Results:We identified 4,970 patients under chronic hemodialysis from Taiwan National Health Insurance Research Database (NHIRD) who had their first coronary stenting between 1 January 2007 and 31 December 2012. After 1:1 propensity score matching, we evaluated clinical outcomes for 1,151 patients in the DES group and 1,151 patients in the matched BMS group. We used ICD-9 CM codes or operation code to identify all outcomes in the study cohort after the index procedure. Primary outcomes including composite endpoints of mortality, non-fatal myocardial infarction (MI), non-fatal stroke, and revascularization after the index procedure were similar in both groups (HR, 0.94; 95% CI: 0.81-1.09; P=0.399). The results were consistent in various generations of DES vs. BMS groups. Secondary outcomes including mortality, non-fatal MI, non-fatal stroke, revascularization, cardiovascular death, hospitalization for heart failure, peptic ulcer bleeding or blood transfusion were similar in both groups, except for a lower risk of peptic ulcer disease in the DES group (HR, 0.59; 95% CI: 0.41-0.83; P=0.003) than the BMS group. CONCLUSIONS In patients on chronic hemodialysis, implantation of DES did not have a better clinical outcome than BMS.

Abstract
Background Inflammation is more common among African Americans (AAs), and it is associated with frailty, poor physical performance, and mortality in community-dwelling older adults. Given the elevated inflammation levels among end-stage renal disease (ESRD) patients, inflammation may be associated with adverse health outcomes such as frailty, physical impairment, and poor health-related quality of life (HRQOL), and these associations may differ between AA and non-AA ESRD patients. Methods One thousand three ESRD participants were recruited at kidney transplant evaluation (4/2014–5/2017), and inflammatory markers (interleukin-6 [IL-6], tumor necrosis factor-a receptor-1 [TNFR1], C-reactive protein [CRP]) were measured. We quantified the association with frailty (Fried phenotype), physical impairment (Short Physical Performance Battery [SPPB]), and fair/poor HRQOL at evaluation using adjusted modified Poisson regression and tested whether these associations differed by race (AA vs. non-AA). Results Non-AAs had lower levels of TNFR1 (9.7 ng/ml vs 14.0 ng/ml, p < 0.001) and inflammatory index (6.7 vs 6.8, p < 0.001) compared to AAs, but similar levels of IL-6 (4.5 pg/ml vs 4.3 pg/ml, p > 0.9) and CRP (4.7 μg/ml vs 4.9 μg/ml, p = 0.4). Non-AAs had an increased risk of frailty with elevated IL-6 (RR = 1.58, 95% CI:1.27–1.96, p < 0.001), TNFR1 (RR = 1.60, 95% CI:1.25–2.05, p < 0.001), CRP (RR = 1.41, 95% CI:1.10–1.82, p < 0.01), and inflammatory index (RR = 1.82, 95% CI:1.44–2.31, p < 0.001). The associations between elevated inflammatory markers and frailty were not present among AAs. Similar results were seen with SPPB impairment and poor/fair HRQOL. Conclusions Non-AAs with elevated inflammatory markers may need closer follow-up and may benefit from prehabilitation to improve physical function, reduce frailty burden, and improve quality of life prior to transplant.

Abstract
Background Nephronophthisis (NPHP) is an autosomal recessive hereditary disease with highly variable clinical characteristics for which 20 genes (NPHP1–20) have been identified. NPHP1 is the major subtype leading to pediatric end-stage renal disease (ESRD). Reports of adult NPHP1 are rare. Case presentation Here, we report a 27-year-old male from a Chinese intermarriage family who was diagnosed as NPHP from clinical presentations and molecular genetic analysis by whole-exome sequencing. The genetic investigation revealed a novel homozygous nonsense mutation, p. E697X,37 and a novel homozygous missense mutation, p. F691 L, in the NPHP1 gene. His parents and fraternal twin harbored heterozygous mutations of the two loci and had no renal symptoms. His elder sister developed ESRD and died at 23 years of age. Conclusions The report indicated that adult NPHP should be taken into consideration for adults with ESRD of uncertain cause. The genotype-phenotype correlation requires further investigation.

Abstract
BACKGROUND To describe the quality of life of adolescents initiating haemodialysis, to determine the factors associated with quality of life, and to assess coping strategies and their impact on quality of life. METHODS All adolescents initiating haemodialysis between September 2013 and July 2015 in French paediatric haemodialysis centres were included. Quality of life data were collected using the "Vécu et Santé Perçue de l'Adolescent et l'Enfant" questionnaire, and coping data were collected using the Kidcope questionnaire. Adolescent's quality of life was compared with age- and sex-matched French control. RESULTS Thirty-two adolescents were included. Their mean age was 13.9 ± 2.0 years. The quality of life score was lowest in leisure activities and highest in relationships with medical staff. Compared with the French control, index, energy-vitality, relationships with friends, leisure activities and physical well-being scores were significantly lower in haemodialysis population. In multivariate analyses, active coping was positively associated with quality of life and especially with energy-vitality, relationships with parents and teachers, and school performance. In contrast, avoidant and negative coping were negatively associated with energy-vitality, psychological well-being and body image for avoidant coping, and body image and relationships with medical staff for negative coping. CONCLUSIONS The quality of life of haemodialysis adolescents, and mainly the dimensions of leisure activities, physical well-being, relationships with friends and energy-vitality, were significantly altered compared to that of the French population. The impact of coping strategies on quality of life seems to be important. Given the importance of quality of life and coping strategies in adolescents with chronic disease, health care professionals should integrate these aspects into care management.

Abstract
BACKGROUND Repair of rotator cuff tears has yielded excellent functional outcomes in recent decades; however, poor outcomes and dissatisfaction have been noted in specific groups. Spontaneous tendon rupture has been reported in patients receiving long-term hemodialysis owing to alteration of tendon structure, which might impede functional recovery after rotator cuff repair. The purpose of the present study was to compare the clinical outcomes between hemodialysis and non-hemodialysis patients after rotator cuff repair. METHODS We retrospectively reviewed patients who underwent mini-open rotator cuff repair from Jan 2013 to Jan 2017. A total of 14 patients under chronic hemodialysis (HD) were matched to non-hemodialysis (NHD) patients at a 1:2 ratio according to age, gender, tear size, severity of fatty infiltration and history of diabetes. Pre- and post-operative functional outcome was assessed using the simple shoulder test (SST), American Shoulder and Elbow Surgeons (ASES), Shoulder Rating Scale of the University of California at Los Angeles (UCLA) and visual analog scale (VAS) scores. Clinical functional outcome at the last follow-up was adopted for comparison of the HD and NHD groups. RESULTS A total of 42 patients were enrolled in this comparative study, with a mean age of 66.64 ± 1.68 years in the HD group and 65.71 ± 5.40 years in the NHD group. At the final clinical assessment, the post-operative functional outcome was significantly improved in both groups (p < 0.001). However, the functional outcome of the HD group was significantly inferior to that of the NHD group in terms of the SST score (6.50 ± 2.24 vs 9.39 ± 1.87, p < 0.001), ASES score (63.17 ± 15.93 vs 86.96 ± 11.43, p < 0.001), UCLA score (20.14 ± 7.71 vs 29.82 ± 5.08, p < 0.001) and VAS score (3.00 ± 0.96 vs 1.21 ± 1.03, p < 0.001). CONCLUSION The improvement of pain and functional improvement of long-term hemodialysis patients were inferior to those of patients without hemodialysis after mini-open rotator cuff repair.

Abstract
Although hemodialysis (HD) is a life-sustaining treatment for the majority of patients with end-stage renal disease, it may adversely affect their psychological status. Depression is highly prevalent among these patients, and it is associated with malnutrition, morbidity and mortality. Recent studies have demonstrated that depression is positively associated with neuroticism and introversion in HD patients. The aim of the present study was to explore the relationship between depression, personality traits (extraversion-introversion, neuroticism, psychoticism) and nutritional status among HD patients. Fifty-two HD patients were assessed via questionnaires for depression (CES-D) and personality traits (EYSENCK, EPQ). Nutritional assessment was conducted through bioelectrical impedance analysis (BIA) and anthropometry measurements (height, post-dialysis weight). The study revealed novel significant correlations. Both post-dialysis weight and phase angle were negatively related to introversion (r = -0.314, p < 0.05 and r = -0.542, p < 0.01, respectively) and depression (r = -0.456, p < 0.01 and r = -0.467, p < 0.01, respectively). This study demonstrates that both depression and introversion are inversely related to adequate nourishment in HD patients and suggests that personality plays an important role in the nutritional status of these patients.

Abstract
BACKGROUND Older patients with end-stage renal disease (ESRD) have experienced diminished quality of life and debilitating symptoms. Conservative management may be a potential treatment option. Currently, limited studies have been conducted about the main outcome of conservative management, including quality of life, symptoms and sleep quality. The aim of this systematic review was to examine the quality of life, symptoms and sleep quality of elderly patients with ESRD undergoing conservative management. METHODS Evidence-based medicine database (JBI and Cochrane) and original literature database (PubMed, Medline, EMbase, Web of Science) were searched up to March 12, 2018. The quality of included papers was evaluated with the Newcastle-Ottawa Scale. RESULTS Eight studies met the inclusion criteria. The total of 1229 patients were involved with an average age of 60.6 ~ 82 years. Patients choosing conservative management were older and more functionally impaired compared to those opting for dialysis. 55% patients undergoing conservative management had stable or improved quality of life and symptoms in prospective cohort study. However, the results revealed that there were no significant differences in quality of life and symptom between conservative management and renal replacement therapy. Only one study assessed quality of life of older patients using SF-36, with a lower score in physical health subscale of conservative management patients than those of renal replacement therapy. Although more than 40% of the patients had poor sleep quality, no significant difference was found between conservative management and renal replacement therapy. Sleep disorders were associated with fatigue and other symptoms. CONCLUSIONS Although there is a limited literature, conservative management is likely to improve quality of life and alleviate symptoms of end-stage renal disease patients with considerable clinical implications mainly in elderly patients. Future study should pay more attention to the various treatment outcomes of conservative management, providing abundant evidence.

Abstract
BACKGROUND In patients with end stage renal disease (ESRD), left ventricular (LV) hypertrophy with impaired LV function, which is called uremic cardiomyopathy (UC) is often observed. The UC historically has been considered a contraindication for kidney transplantation (KTx). Currently, moderate LV dysfunction does not exclude the possibility of KTx. The amelioration of uremia after KTx improved cardiac function in patients with LV dysfunction. There is a little information on the function of the left atrium (LA) after the KTx procedure. There are no studies evaluating (LA) changes in patients with UC after KTx and determining the possibility of inhibiting the occurrence of LA unfavourable changes (remodelling) and even a possible LA recovery process (reverse remodelling) as a result of a successful KTx. The aim of the study was to assess the LA reverse remodelling in patients with ESRD undergoing KTx. METHODS The study group consisted of 42 patients, aged 43.3 ± 12.6 followed for 36 months after a deceased donor KTx. The patients were studied at five time points: 1, 3, 6, 12 and 36 months after KTx. In all patients transthoracic echocardiography was performed in order to assess the following LA planimetric parameters: LAmax, LAmin, LAwaveP. LAshortmax, LAshortmin, LAshortwaveP, LAlongmax, LAlongmin, LAlongwaveP, LAcircmax and LAareamax, volumentric parameters: LA volume (LAV), LA volume index (LAVI), and hemodynamic indices: LA ejection fraction (LAEF), LA active emptying fraction (LAAE), LA passive emptying fraction (LAPE), LA index of expansion (LAIE) and LA fractional shortening (LAFS). RESULTS The LAVI values were 34.63 ± 10.34 ml/m2, 32.24 ± 9.59 ml/m2 (p < 0,001), 31.36 ± 9.20 ml/m2 (p < 0,001), 28.29 ± 8.32 ml/m2 (p < 0,001) and 27.57 ± 8.40 ml/m2 (p < 0,001), after: 1, 3, 6, 12 and 36 months after KTx, respectively. The reduction of the LA size was accompanied by gradual LA contractility improvement, which was manifested as an increase of the LA hemodynamic indices such as LAEF, LAAE, LAIE, LAFS and a decrease of LAPE. CONCLUSIONS LA remodelling secondary to atrial uraemic cardiomyopathy is an example of complex cardiomyopathy with elements characteristic of both congestive and infiltrative cardiomyopathy. Early LAVI reduction post KTx mostly depends on changed haemodynamic conditions, whereas the main reason for further decrease of LAVI values is related to resolution of uraemic toxaemia.
