Whether fracture rates, overall and by fracture site, vary by cause of kidney failure in patients receiving dialysis is unknown.

Using the US Renal Data System, we compared fracture rates across seven causes of kidney failure in patients who started dialysis between 1997 and 2014. We computed unadjusted and multivariable adjusted proportional sub-distribution hazard models, with fracture events (overall, and by site) as the outcome and immunoglobulin A nephropathy as the reference group. Kidney transplantation and death were competing events.

Among 491 496 individuals, with a median follow-up of 2.0 (25%, 75% range 0.9-3.9) years, 62 954 (12.8%) experienced at least one fracture. Patients with diabetic nephropathy, vasculitis or autosomal polycystic kidney disease (ADPKD) had the highest (50, 46 and 40 per 1000 person-years, respectively), and patient with lupus nephritis had the lowest (20 per 1000 person-years) fracture rates. After multivariable adjustment, diabetic nephropathy [hazard ratio (HR) 1.4mediators including medications and measures or bone biomarkers.

Fracture risk, overall and by fracture site, varies by cause of end-stage kidney disease. Future work to determine underlying pathogenic mechanisms contributing to differential risks might inform more tailored treatment strategies. Our study was limited by lack of data regarding numerous potential confounders or mediators including medications and measures or bone biomarkers.Barriers to accessing home dialysis became a matter of life and death for many patients with kidney failure during the coronavirus disease 2019 (COVID-19) pandemic. Peritoneal dialysis (PD) is the more commonly used home therapy option. This article provides a comprehensive analysis of PD catheter insertion procedures as performed around the world today, barriers impacting timely access to the procedure, the impact of COVID-19 and a roadmap of potential policy solutions. To substantiate the analysis, the article includes a survey of institutions across the world, with questions designed to get a sense of the regulatory frameworks, barriers to conducting the procedure and impacts of the pandemic on capability and outcomes. Based on our research, we found that improving patient selection processes, determining and implementing correct insertion techniques, creating multidisciplinary teams, providing appropriate training and sharing decision making among stakeholders will improve access to PD catheter insertion and facilitate greater uptake of home dialysis. Additionally, on a policy level, we recommend efforts to improve the awareness and feasibility of PD among patients and the healthcare workforce, enhance and promulgate training for clinicians-both surgical and medical-to insert PD catheters and fund personnel, pathways and physical facilities for PD catheter insertion.Chronic kidney disease (CKD) is set to become the fifth-leading global cause of death by 2040. This illustrates the many unknowns regarding its pathogenesis and therapy. A key unknown relates to the therapeutic impact of the interaction between CKD and the gut microbiome. The normal gut microbiome is essential for body homeostasis. There is evidence for multiple interactions between the microbiota and CKD-its causes, comorbidities and therapeutic interventions-that are only starting to be unraveled. Thus uremic retention products, such as urea itself, modify the gut microbiota biology and both dietary and drug prescriptions modify the composition and function of the microbiota. Conversely, the microbiota may influence the progression and manifestations of CKD through the production of biologically active compounds (e.g. short-chain fatty acids such as butyrate and crotonate) and precursors of uremic toxins. The present review addresses these issues and their relevance for novel therapeutic approaches ranging from dietary interventions to prebiotics, probiotics, synbiotics and postbiotics, to the prevention of the absorption of microbial metabolites and to increased clearance of uremic toxins of bacterial origin through optimized dialysis techniques or blockade of tubular cell transporters.Membranoproliferative glomerulonephritis (MPGN) comprises a histologic pattern of glomerular injury with different underlying diseases. Here we report on a 47-year-old female with rapidly progressive glomerulonephritis (RPGN) on top of a previously diagnosed idiopathic MPGN after receiving the first dose of the Pfizer-BioNTech coronavirus disease 2019 (COVID-19) mRNA vaccine. After aggressive immunosuppression her serum creatinine returned to normal values, along with reduction of proteinuria. Recently, numerous publications have reported an association of glomerular diseases with COVID-19 vaccination. Our case presents to the best of our knowledge the first occurrence of possible association of COVID-19 mRNA vaccination with a crescentic form of MPGN.

Recently, several pharmaceutical companies have developed new medium cut-off (MCO) dialyzers for expanded hemodialysis (HDx). This study aimed to compare the safety and efficacy of four MCO dialyzers, against each other and versus high-flux hemodialysis (HD) and post-dilution hemodiafiltration (HDF).

A prospective study was carried out on 23 patients who underwent six dialysis sessions two sessions with the FX80 Cordiax in HD and HDF, and four HDx sessions with the Phylther 17-SD, Vie-18X, Elisio HX19 and Theranova 400 dialyzers. The reduction ratios (RRs) of urea, creatinine, β

-microglobulin, myoglobin, kappa free immunoglobulin light chain (κFLC), prolactin, α

-microglobulin, α

-acid glycoprotein, lambda (λFLC) and albumin were compared. Dialysate albumin loss was also measured.

The differences in efficacy between the evaluated dialyzers were minimal in small molecules and even up to the size of β

-microglobulin. The main differences were found between myoglobin, κFLC, prolactin, α

-microglobulin and λFLC RRs, in which all four MCO dialyzers, with similar efficacy, were clearly superior to HD and slightly inferior to HDF treatment. Albumin losses in the dialysate with HD dialyzers were <1 g and between 1.5 and 2.5 g in HDx and HDF. The global removal score values were similar in all four HDx treatments, and again significantly higher than those with HD.

The results of the four MCO dialyzers evaluated in this study showed good efficiency, with no significant performance differences between them while being completely safe in terms of albumin loss. Likewise, the study confirms the superiority of HDx over high-flux HD with an efficacy close to that of post-dilution HDF.

The visit-to-visit variability (VVV) in blood pressure (BP) is an important risk factor for stroke and coronary heart disease and may also be associated with kidney damage and the development of chronic kidney disease (CKD). Data on the association between VVV in BP and the risk of CKD progression among patients with immunoglobulin A nephropathy (IgAN) are limited. We aimed to evaluate the relationships of VVV in BP with the progression of IgAN.

We assessed 1376 patients with IgAN at Peking University First Hospital. The main VVV in BP was expressed as the standard deviation (SD), coefficient of variation (CV) and average real variability (ARV). The associations of variability in BP with composite kidney disease progression events, defined as a 50% decline in estimated glomerular filtration rate (eGFR) and kidney failure, were examined using Cox models.

During a median follow-up of 44.1months (interquartile range 23.0-76.7), 247 (18.0%) patients experienced composite kidney disease progression events. With a higher SD in systolic BP (SBP) values, the risk of kidney disease progression events increased hazard ratio [HR] 1.07 [95% confidence interval (CI) 1.03-1.11];

<.001 after maximal adjustment, including baseline SBP and mean SBP during the first 12-month period. Using the first quartile of SD SBP values as the reference, the risk of composite kidney disease progression events was higher among patients with higher SD SBP values; the HR was 2.12 (95% CI 1.31-3.44) in the highest quartile (

for trend<.001). A similar trend could be observed when analysing the SD of diastolic BP, but the risk was not significantly increased. The associations were similar when analysed with the CV and ARV.

SBP variability was significantly associated with kidney disease progression in IgAN.

Acute kidney injury (AKI) is associated with short- and long-term complications but the consequences of the AKI-to-CKD transition are still poorly understood. We aimed to evaluate the association between the AKI-to-CKD transition and the long-term risk of infection.

This retrospective study included patients admitted in a tertiary hospital with community-acquired AKI in 2013 and 2014 who had their estimated glomerular filtration rate (eGFR) assessed at 3months (±2weeks) after serum creatinine peaked in the AKI episode. Key exclusion criteria were baseline CKD or confounding factors (active neoplasia, primary immunodeficiency, human immunodeficiency virus, immunosuppressive drugs). this website The association between the AKI-to-CKD transition (defined as an eGFR <60ml/min/1.73m

at 3months) and long-term infections (defined using clinical features, blood/urine analysis, cultures and imaging) was assessed during a follow-up of 9months (range 2-56).

Among the 1731 patients admitted with AKI, 367 (21%) were included in the present analysis (64% male, 71±15years). Three months after AKI, 159 (43%) developed AKI-to-CKD transition. Baseline and post-AKI eGFR were independent predictors of AKI-to-CKD transition [hazard ratio (HR) 0.97,

=.044 and HR 0.96,

<.001, respectively].During follow-up, 153 (42%) patients developed an infection. Factors associated with infection were older age, cognitive impairment, lower post-AKI eGFR, eGFR loss from baseline to 3months and AKI-to-CKD transition. Adjusted Cox regression showed that baseline eGFR, 3-month eGFR, eGFR loss and AKI-to-CKD transition were independent predictors of the long-term risk of infection.

The AKI-to-CKD transition independently predicts the long-term risk of infection following an episode of AKI.

Kidney function declines naturally with advancing age. Therefore an age-adapted estimated glomerular filtration rate (eGFR) threshold has been proposed instead of the fixed threshold for CKD definition. This study aims to describe and compare the profile of CKD patients defined by these two criteria in a Chinese population.

We recruited adult participants with selected biochemical tests from the Chinese Physiological Constant and Health Condition survey conducted from 2007 to 2011, with the GFR estimated by the Chronic Kidney Disease Epidemiology Collaboration formula. The age-adapted threshold of eGFR is 75, 60 and 45ml/min/1.73m

for the population <40years of age, 40-64years and >64years, respectively. The fixed threshold is 60ml/min/1.73m

for all ages.

Among the recruited 23438 participants, 480 were diagnosed with CKD by fixed threshold criteria, while 391 were diagnosed with CKD by age-adapted criteria. Patients diagnosed by fixed threshold criteria were significantly older (66.4 versus 43.
