Hallmarks for Thrombotic and Hemorrhagic Risks in Chronic Kidney Disease Patients.

Chronic kidney disease (CKD) is a global health issue causing a significant health burden. CKD patients develop thrombotic and hemorrhagic complications, and cardiovascular diseases are associated with increased hospitalization and mortality in this population. The hemostatic alterations are multifactorial in these patients; therefore, the results of different studies are varying and controversial.

Use of Proton Pump Inhibitors Is Not Associated with Post-Dialysis Fatigue and Time of Recovery after Dialysis in Patients on Maintenance Hemodialysis.

: To define if the use of proton pump inhibitors (PPI) is associated with PDF prevalence and characteristics and with time of recovery after dialysis in patients on maintenance hemodialysis. : Patients were defined as experiencing PDF if they spontaneously offered this complaint when asked the open-ended question: "Do you feel fatigued after dialysis?". Time of recovery after dialysis (TIRD) was also assessed for each patient.

Coupling Osmotic Efficacy with Biocompatibility in Peritoneal Dialysis: A Stiff Challenge.

Peritoneal dialysis (PD) is a home-based efficacious modality for the replacement of renal function in end-stage kidney failure patients, but it is still under-prescribed. A major limitation is the durability of the dialytic technique. Continuous exposure of the peritoneum to bioincompatible conventional glucose-based solutions is thought to be the main cause of the long-term morpho-functional peritoneal changes that eventually result in ultrafiltration failure.

Treatment Options for Anemia in Kidney Transplant Patients: A Review.

Anemia is common after kidney transplantation. The etiology may be multifactorial, such as causes of anemia in the general population and causes that are unique to the kidney transplant setting. Posttransplant anemia, particularly when severe, may be associated with adverse effects such as graft failure, mortality, and a decline in kidney function.

Biomarker-Development Proteomics in Kidney Transplantation: An Updated Review.

Kidney transplantation (KT) is the optimal therapeutic strategy for patients with end-stage renal disease. The key to post-transplantation management is careful surveillance of allograft function. Kidney injury may occur from several different causes that require different patient management approaches.

Chyloperitoneum in Peritoneal Dialysis Secondary to Calcium Channel Blocker Use: Case Series and Literature Review.

Chyloperitoneum (chylous ascites) is a rare complication of peritoneal dialysis (PD). Its causes may be traumatic and nontraumatic, associated with neoplastic disease, autoimmune disease, retroperitoneal fibrosis, or rarely calcium antagonist use. We describe six cases of chyloperitoneum occurring in patients on PD as a sequel to calcium channel blocker use.

Efficacy of hemoperfusion with Seraph-100 in series with single pass albumin dialysis in acute hepatitis B infection: A case report.

Acute and acute-on-chronic liver failure is a cause of death in patients suffering from viral hepatitis, and many cases need liver transplantation. Infection from hepatitis B virus may range from asymptomatic to severe acute and fulminant hepatitis. In this setting, treatment is mainly supportive as there is no consensus on antiviral therapy based on non-nucleoside reverse transcriptase inhibitors.

Post-dialysis fatigue: Comparison of bicarbonate hemodialysis and online hemodiafiltration.

Introduction: The present cross-sectional study aimed to compare the prevalence, the characteristics of post-dialysis fatigue and the length of recovery time after hemodialysis in prevalent end-stage renal disease patients (ESRD) receiving bicarbonate hemodialysis (HD) or hemodiafiltration (HDF).

Methods: Patients were suffering from post-dialysis fatigue if they spontaneously offered this complaint when asked the open-ended question: "Do you feel fatigued after dialysis?". Moreover, each patient was invited to rate the intensity, duration, and frequency of post-dialysis fatigue from 1 to 5.

Vitamin E (Alpha-Tocopherol) Metabolism and Nutrition in Chronic Kidney Disease.

Vitamin E (alpha-tocopherol) is an essential micronutrient and fat-soluble antioxidant with proposed role in protecting tissues from uncontrolled lipid peroxidation. This vitamin has also important protein function and gene modulation effects. The metabolism of vitamin E depends on hepatic binding proteins that selectively retain food alpha-tocopherol for incorporation into nascent VLDL and tissue distribution together with esterified cholesterol and triglycerides.

Biocompatibility of Surface-Modified Membranes for Chronic Hemodialysis Therapy.

Hemodialysis is a life-sustaining therapy for millions of people worldwide. However, despite considerable technical and scientific improvements, results are still not fully satisfactory in terms of morbidity and mortality. The membrane contained in the hemodialyzer is undoubtedly the main determinant of the success and quality of hemodialysis therapy.

[Which future solutions for peritoneal dialysis?].

Peritoneal dialysis is an efficient renal replacement therapy for uremic patients but is currently under-prescribed. This is partly due to the unfavorable effects on peritoneal morphology and function (bioincompatibility) of current glucose-based solutions. Use of standard solutions can cause several peritoneal alterations including inflammation, mesothelial to mesenchymal transition, and neo-angiogenesis.

IgA Deficiency and Membranoproliferative Glomerulonephritis: A Case Report.

Background: Immunoglobulin A deficiency (IgAD) is the most common form of primary immunodeficiency in western countries. It can be associated with the development of autoimmune diseases both in adults and in children even though the exact pathophysiology is not fully defined.

Case Presentation: We report here a case of a young patient who developed nephrotic syndrome secondary to membranoproliferative glomerulonephritis associated with the incidental finding of IgAD.

Predialysis and Dialysis Therapies Differently Affect Nitric Oxide Synthetic Pathway in Red Blood Cells from Uremic Patients: Focus on Peritoneal Dialysis.

Red blood cells (RBCs) have been found to synthesize and release both nitric oxide (NO) and cyclic guanosine monophosphate (cGMP), contributing to systemic NO bioavailability. These RBC functions resulted impaired in chronic kidney disease (CKD). This study aimed to evaluate whether predialysis (conservative therapy, CT) and dialysis (peritoneal dialysis, PD; hemodialysis, HD) therapies used during CKD progression may differently affect NO-synthetic pathway in RBCs.

Formalin-fixed paraffin-embedded renal biopsy tissues: an underexploited biospecimen resource for gene expression profiling in IgA nephropathy.

Primary IgA nephropathy (IgAN) diagnosis is based on IgA-dominant glomerular deposits and histological scoring is done on formalin-fixed paraffin embedded tissue (FFPE) sections using the Oxford classification. Our aim was to use this underexploited resource to extract RNA and identify genes that characterize active (endocapillary-extracapillary proliferations) and chronic (tubulo-interstitial) renal lesions in total renal cortex. RNA was extracted from archival FFPE renal biopsies of 52 IgAN patients, 22 non-IgAN and normal renal tissue of 7 kidney living donors (KLD) as controls.

Nephrotoxicity Associated with Novel Anticancer Agents (Aflibercept, Dasatinib, Nivolumab): Case Series and Nephrological Considerations.

Cancer patients have an incidence of about 60% kidney disease development and are at elevated risk of acute renal damage. Kidney disease in these patients is frequently associated with nephrotoxicity from the ongoing oncological treatment. New anticancer therapeutic strategies, such as targeted therapies and immunotherapies, offer substantial benefits in the treatment of many neoplasms.

Erythropoietin induces miRNA-210 by JAK2/STAT5 signaling in PBMCs of End-stage Renal Disease patients.

Anemia of chronic kidney disease is associated with blunted response/resistance to erythropoietin-stimulating agents (ESAs) in hemodialysis (HD) patients. Several molecules have been successfully associated with ESA responsiveness; however, none of them is now considered a valid therapeutic biomarker of erythropoietin resistance in these patients. We performed an evaluation of the level of specific plasma circulating miRNAs in blood samples of HD patients, in relation to ESA treatment, with a follow-up of 1 year (T0-T3).

Intensity, Duration, and Frequency of Post-Dialysis Fatigue in Patients on Chronic Haemodialysis.

Background: Although frequent and debilitating, little is known about the characteristics of post-dialysis fatigue (PDF).

Objective: To characterise the intensity, duration and frequency of PDF and the associated variables in patients on chronic haemodialyses.

Design: Prospective, observational and multicenter study.

Urinary Peptidomic Biomarkers in Kidney Diseases.

In order to effectively develop personalized medicine for kidney diseases we urgently need to develop highly accurate biomarkers for use in the clinic, since current biomarkers of kidney damage (changes in serum creatinine and/or urine albumin excretion) apply to a later stage of disease, lack accuracy, and are not connected with molecular pathophysiology. Analysis of urine peptide content (urinary peptidomics) has emerged as one of the most attractive areas in disease biomarker discovery. Urinary peptidome analysis allows the detection of short and long-term physiological or pathological changes occurring within the kidney.

Recovery Time after Hemodialysis Is Inversely Associated with the Ultrafiltration Rate.

Introduction: The present study aimed to determine the variables that are associated with a longer dialysis recovery time (DRT) and to define the relationship that exists between DRT and the ultrafiltration rate (UFR) in prevalent chronic hemodialysis (CHD) patients.

Methods: We studied 210 prevalent CHD of 5 hemodialysis units in Central Italy. Patients were invited to answer to the question: "How long does it take you to recover from a dialysis session?" Answers to this question were subsequently converted into minutes.

Prevalence and Severity of Postdialysis Fatigue Are Higher in Patients on Chronic Hemodialysis With Functional Disability.

The aim of the present study was to determine the intensity, duration, frequency and prevalence of postdialysis fatigue (PDF) in patients on chronic hemodialysis (PCD) with and without functional disability. Patients underwent assessment of functional ability by the Katz ADL (activity daily living) questionnaire and the Lawton and Brody scale for the instrumental activity daily living (IADL) fatigue using the SF-36 Vitality Subscale, comorbidity through the Charlson comorbidity score index (CDI), and time of recovery after hemodialysis (TIRD). We studied 271 PCD.

Proteomic Characterization of a New asymmetric Cellulose Triacetate Membrane for Hemodialysis.

Purpose: The artificial membrane inside the haemodialyzer is the main determinant of the quality and success of haemodialysis therapy. The performances of haemodialysis membranes are highly influenced by the interactions with plasma proteins, which in turn are related to the physical and chemical characteristics of the membrane material. The present cross-over study is aimed to analyse the haemodialysis performance of a newly developed asymmetric cellulose triacetate membrane (ATA) in comparison to the conventional parent symmetric polymer (CTA).

Examining hemodialyzer membrane performance using proteomic technologies.

The success and the quality of hemodialysis therapy are mainly related to both clearance and biocompatibility properties of the artificial membrane packed in the hemodialyzer. Performance of a membrane is strongly influenced by its interaction with the plasma protein repertoire during the extracorporeal procedure. Recognition that a number of medium-high molecular weight solutes, including proteins and protein-bound molecules, are potentially toxic has prompted the development of more permeable membranes.

[Update on proteomic use in hemodialysis].

Application of proteomics has become one of the leading experimental disciplines for increased understanding of the key role played by proteins and protein-protein interactions in all aspects of cell function. There is an increasing use of proteomic technologies for investigation into renal replacement therapy such as hemodialysis. In the last 10 years, the application of shotgun bottom-up liquid chromatography-mass spectrometry/mass spectrometry approaches has been successfully applied to research in uremic toxicity, with the discovery of novel uremic toxins and the potential to delineate a precise molecular approach to defining the biochemical nature of uremia.
