Push toward pre-emptive kidney transplantation - for sure?

Pre-emptive kidney transplantation (PKT) has long been considered the optimal treatment for patients with end-stage chronic kidney disease (CKD) seeking the most favourable long-term outcomes. However, the significant growth in transplant procedures over recent decades has led to a notable increase in wait-listed patients and a disproportionate demand for donor organs. This situation necessitates a re-evaluation of transplantation timing and the establishment of rational indications from both societal and clinical perspectives.

Novel approach to assess sarcopenia in children with inflammatory bowel disease.

Introduction: Sarcopenia is associated with poor clinical outcomes in chronic diseases. Our study aimed to characterize body composition (BC) parameters in patients with inflammatory bowel disease (IBD) and compare skeletal muscle mass (SMM) parameters with the healthy pediatric population.

Methods: BC of healthy controls (HC) and of patients with IBD were measured via multifrequency bioelectrical impedance (InBody 720 device) in a cross-sectional manner.

Budapest nephrology school - 30 years of history - from modest start to an international success: systematic summary of the 27th BNS held between 28 August and 2 of September 2023.

Budapest Nephrology School (BNS) could have celebrated its 30th event if it had not been interrupted by COVID pandemic for a few years. Yet, the organization of 27th BNS in August 2023 resumed its successful and traditional activities at Semmelweis University, in the beautiful central European city of Budapest. In over two decades, BNS has faithfully adapted to the changes and developments of medical science and clinical nephrology, the fact which has kept it unique and attractive for nephrologists from across the globe.

Get to the heart of pediatric kidney transplant recipients: Evaluation of left- and right ventricular mechanics by three-dimensional echocardiography.

Background: Kidney transplantation (KTX) markedly improves prognosis in pediatric patients with end-stage kidney failure. Still, these patients have an increased risk of developing cardiovascular disease due to multiple risk factors. Three-dimensional (3D) echocardiography allows detailed assessment of the heart and may unveil distinct functional and morphological changes in this patient population that would be undetectable by conventional methods.

Body composition, physical activity, and quality of life in pediatric patients with inflammatory bowel disease on anti-TNF therapy-an observational follow-up study.

Background: Poor outcome of inflammatory bowel disease (IBD) is associated with malnutrition. Our aim was to compare body composition (BC) and physical activity (PA) between patients with IBD and healthy controls, and to assess the changes in BC, PA and health related quality of life (HRQoL) in children with IBD during anti-TNF therapy.

Methods: 32 children with IBD (21 with Crohn's disease (CD), (age: 15.

Graft Arterial Dissection and Thrombosis After Kidney Transplantation With Undiagnosed Fibromuscular Dysplasia From a Deceased Donor: Case Report and Review.

Background: Fibromuscular dysplasia (FMD), a relatively frequent arterial deformity with an estimated prevalence of 2% to 6% has been sporadically reported during deceased donor kidney donations. Only 8 case reports are available in the previous literature.

Case Presentation: In our work, implantation of 2 kidneys from the same deceased donor with macroscopically evident and later histologically confirmed FMD are presented, one of which ended up as acute arterial complication.

The Importance of Arterial Stiffness Assessment in Patients with Familial Hypercholesterolemia.

Cardiovascular diseases are still the leading cause of mortality due to increased atherosclerosis worldwide. In the background of accelerated atherosclerosis, the most important risk factors include hypertension, age, male gender, hereditary predisposition, diabetes, obesity, smoking and lipid metabolism disorder. Arterial stiffness is a firmly established, independent predictor of cardiovascular risk.

Subclinical cardiac dysfunction in pediatric kidney transplant recipients identified by speckle-tracking echocardiography.

Background: Kidney transplantation (KTx) improves prognosis in children with kidney failure; still, these patients are prone to cardiovascular damage due to multiple risk factors. Our aim was to assess myocardial structure and function in pediatric KTx by conventional and speckle-tracking echocardiography (STE) in association with established cardiovascular risk factors.

Methods: Forty-two KTx and 39 healthy age- and gender-matched children were evaluated.

Follow-Up of Blood Pressure, Arterial Stiffness, and GFR in Pediatric Kidney Transplant Recipients.

Pediatric renal transplant recipients (RTx) were studied for longitudinal changes in blood pressure (BP), arterial stiffness by pulse wave velocity (PWV), and graft function. 52 RTx patients (22 males) were included; office BP (OBP) and 24 h BP monitoring (ABPM) as well as PWV were assessed together with glycemic and lipid parameters and glomerular filtration rate (GFR) at 2.4[1.

COVID-19 vaccinations: The unknowns, challenges, and hopes.

The entire world has been suffering from the coronavirus disease 2019 (COVID-19) pandemic since March 11, 2020. More than a year later, the COVID-19 vaccination brought hope to control this viral pandemic. Here, we review the unknowns of the COVID-19 vaccination, such as its longevity, asymptomatic spread, long-term side effects, and its efficacy on immunocompromised patients.

Cross-sectional comparison of office and ambulatory pulse wave velocity by two methods, and their changes after lifestyle or medical interventions in hypertension.

Objective: Pulse wave velocity (PWV), the most accepted biomarker of arterial stiffening can be measured by different methods and in the past decade, its 24 h monitoring has also become available. The aim of our study was to compare office and ambulatory PWVs and in a proportion of patients to compare the changes of PWVs after the initiation of lifestyle modifications or antihypertensive medication.

Methods: Office carotid-femoral PWV was measured with the tonometric PulsePen device (PP PWV), first hour and 24 h ambulatory oscillometric PWVs were evaluated with Mobil-O-Graph (MOB first hour PWV and MOB 24 h PWV, respectively).

Comparison of Different Cardiovascular Risk Score and Pulse Wave Velocity-Based Methods for Vascular Age Calculation.

Background: The calculation of vascular age can help patients understand the importance of adherence to healthy lifestyle and medications. However, multiple methods are available to calculate vascular age and no comparison data is available yet. Our aim was to evaluate vascular age based on the Framingham Risk Score (FRS), the Systematic COronary Risk Evaluation (SCORE) and carotid-femoral pulse wave velocity (PWV).

Oxygenated End-Hypothermic Machine Perfusion in Expanded Criteria Donor Kidney Transplant: A Randomized Clinical Trial.

Importance: Continuous hypothermic machine perfusion during organ preservation has a beneficial effect on graft function and survival in kidney transplant when compared with static cold storage (SCS).

Objective: To compare the effect of short-term oxygenated hypothermic machine perfusion preservation (end-HMPo2) after SCS vs SCS alone on 1-year graft survival in expanded criteria donor kidneys from donors who are brain dead.

Design, Setting, And Participants: In a prospective, randomized, multicenter trial, kidneys from expanded criteria donors were randomized to either SCS alone or SCS followed by end-HMPo2 prior to implantation with a minimum machine perfusion time of 120 minutes.

The incidence of cytomegalovirus infection after deceased-donor kidney transplantation from hepatitis-C antibody positive donors to hepatitis-C antibody negative recipients.

Background: Deceased-donor kidney transplantation (KT) from hepatitis C (HCV)-infected donors into HCV-uninfected recipients (HCV D+/R-) could become standard care in the near future. However, HCV viral replication by viral transmission might lead to a higher incidence of cytomegalovirus (CMV) infection in these recipients.

Methods: A national-registry-based retrospective cohort study was conducted using the Scientific Registry of Transplant Recipients (SRTR) data set.

[Guidance on the special care of liver or kidney transplant recipients diagnosed with COVID-19].

Due to the COVID-19 pandemic caused by infection with the novel, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), transplant medicine also had to face a new, hitherto unknown challenge. To be prepared for any possibility, we consider it important to summarize the current knowledge regarding COVID-19 of liver and kidney transplant patients. Very early reports from Spanish and French registry recorded fatality rates of 18.

Factors associated with hepatitis C antibody seroconversion after transplantation of kidneys from hepatitis C infected donors to hepatitis C naïve recipients.

Evaluation of affective temperaments and arterial stiffness in different hypertension phenotypes.

Affective temperaments (depressive, anxious, irritable, hyperthymic, and cyclothymic) are stable parts of personality and describe emotional reactivity to external stimuli. Their relation to psychopathological conditions is obvious, but less data are available on their relationship with cardiovascular disorders. The aim of this study was to evaluate affective temperaments and hemodynamic and arterial stiffness parameters in healthy subjects (Cont), in white-coat hypertensive (WhHT) patients, and in non-resistant (non-ResHT) and resistant hypertensive (ResHT) patients.

Distance measurement for pulse wave velocity estimation in pediatric age: Comparison with intra-arterial path length.

Background And Aims: Central pulse wave velocity (PWV) is a marker of arterial stiffness and is calculated by dividing the pulse wave travel distance by the transit time. However, there is no consensus as to the ideal distance measurement in children. The aim of our study was to identify the more reliable method to assess the distance measurement in the pediatric age.

Lack of Association between Pretransplant Donor-Specific Antibodies and Posttransplant Kidney Outcomes in Simultaneous Liver-Kidney Transplant Recipients with Rabbit Anti-Thymocyte Globulin Induction and Steroid-Free Protocol.

Introduction And Objective: The impact of pretransplant donor-specific antibodies (DSAs), especially class II DSAs, on kidney allograft outcomes remains unclear in simultaneous liver-kidney transplantation (SLKT) recipients.

Methods: We examined 85 recipients who consecutively underwent SLKT between 2009 and 2018 in our center. Associations between pretransplant DSA and worsening kidney function (WKF), kidney allograft loss, composite kidney outcome (WKF and/or antibody-mediated rejection and/or death-censored kidney allograft loss), death with functioning graft, and overall mortality were examined in survival analysis.
