Is the combination of linagliptin and allopurinol better prophylaxis against post-contrast acute kidney injury? A multicenter prospective randomized controlled study.

Background: Patients with diabetic kidney disease (DKD) are at increased risk to develop post-contrast acute kidney injury (AKI). Diabetic patients under dipeptidyl peptidase 4 inhibitors (DPP4Is) experience a lower propensity to develop AKI. We speculated that linagliptin as a single agent or in combination with allopurinol may reduce the incidence of post-contrast AKI in stage 3-5 chronic kidney disease (CKD) patients with underlying DKD.

Subjective global assessment of nutrition, dialysis quality, and the theory of the scientific method in Nephrology practice.

In an era of evidence-based medicine and dialysis performance measures, there is strong motivation to find specific, objective, quantifiable, and reproducible parameters to characterize the clinical condition of chronic kidney disease patients and to present population-wide statistics that may describe quality of care in dialysis centers. Yet, in the last three decades, several studies demonstrated that while parameters including Kt/V urea, serum phosphorus, parathyroid hormone, serum cholesterol fulfill all these criteria, efforts to optimize these lab parameters failed to improve survival on dialysis. However, subjective assessments of nutrition including subjective global assessment and malnutrition-inflammation score, while not ideally suited for statistical analysis and not optimal from the point of view of scientific methodology due to their general, semi-quantifiable, subjective nature have, nevertheless, proved themselves as some of the strongest predictors of clinical outcomes in the dialysis population.

Systematic Review and Meta-Analysis of Antibiotic and Antimicrobial Lock Solutions for Prevention of Hemodialysis Catheter-Related Infections.

Catheter-related bloodstream infection (CRBSI) with hemodialysis catheters are associated with increased mortality, morbidity and pose significant financial burden on healthcare. Antibiotic and antimicrobial locking solutions are effective in reducing risk of CRBSI. From inception to April 2020, we looked for relevant clinical controlled trials throughout the following databases: EBSCO, PubMed, Cochrane CENTRAL, MEDLINE, EMBASE, clinicaltrial.

The association of overhydration with megafistulas in hemodialysis patients.

Diffuse enlargements of arteriovenous dialysis fistulas customarily attributed to either excessive arterial inflow or central outflow stenosis. The relationship between volume status and clinically enlarged (arteriovenous) fistula (CEF) formation in end-stage renal disease (ESRD) patients is not well understood. We assessed the pre-dialysis bioimpedance spectroscopy-measured percentage of overhydration (OH%) in 13 prevalent dialysis patients with CEF development and negative angiography and compared the results with those of 52 control dialysis patients (CONTR).

Correction to: Therapeutic hypernatremia management during continuous renal replacement therapy with elevated intracranial pressures and respiratory failure.

The authors would like to report an error in the formula describing the correction factor for the protein content in the serum/plasma.

Therapeutic hypernatremia management during continuous renal replacement therapy with elevated intracranial pressures and respiratory failure.

Cerebral edema and elevated intracranial pressure (ICP) are common complications of acute brain injury. Hypertonic solutions are routinely used in acute brain injury as effective osmotic agents to lower ICP by increasing the extracellular fluid tonicity. Acute kidney injury in a patient with traumatic brain injury and elevated ICP requiring renal replacement therapy represents a significant therapeutic challenge due to an increased risk of cerebral edema associated with intermittent conventional hemodialysis.

The association of overhydration with chronic inflammation in chronic maintenance hemodiafiltration patients.

Introduction: Achieving euvolemia is one of the major challenges when treating end-stage renal disease (ESRD) patients receiving maintenance renal replacement therapy. Fluid overload is recognized as an independent predictor of mortality in ESRD, but its association with chronic inflammation is less well explored especially in chronic maintenance hemodiafiltration.

Methods: We performed a cross-sectional study of 87 prevalent ESRD patients receiving chronic maintenance hemodiafiltration (vintage 66.

Celiac plexus block increases quality of life in patients with pancreatic cancer.

Background: Pancreatic cancer is a malignant disease with a high mortality rate and severe pain that is challenging to manage. To reduce the excruciating abdominal pain, opioids and adjuvant agents are conventionally used.

Objectives: PRNCPB is a treatment of neural therapy.

Benefits, challenges, and opportunities using home hemodialysis with a focus on Mississippi, a rural southern state.

The prevalence of end-stage renal disease continues to increase in the United States with commensurate need for renal replacement therapies. Hemodialysis continues to be the predominant modality, though less than 2% of these patients will receive hemodialysis in their own home. While home modalities utilizing peritoneal dialysis have been growing, home hemodialysis (HHD) remains underutilized despite studies showing regression in left ventricular mass, improved quality of life, reduced depressive symptoms, and decreased postdialysis recovery time.

Successful Practice Transitioning Between Hemodialysis and Hemodiafiltration in Outpatient Units: Ten Key Issues for Physicians to Remember.

Hemodiafiltration (HDF) during chronic renal replacement therapy (RRT) is a relatively new practice phenomenon, emerging over the last two decades. While the technological platforms utilized during chronic RRT are in many cases similar or effectively identical to conventional hemodialysis (HD), significant differences may emerge in daily practice. Several authors of this review moved practice site between the United States and the European Union and transitioned from an HD-based practice to predominantly HDF-practicing networks.

Peritoneal dialysis: The unique features by compartmental delivery of renal replacement therapy.

Despite decades of research, the clinical efficacy of peritoneal dialysis (PD) remains enigmatic. We may wonder why the modality fail in some patients but perhaps the more proper question would be, why it works in so many? We know that the contribution of residual renal function (RRF), more so than in hemodialysis, is critically important to the well-being of many of the patients. Unique features of the modality include the relatively low volume of dialysate fluid needed to provide effective uremic control and the disproportionate tendency for both hypokalemia and hypoalbuminemia, when compared to hemodialysis.

Volume-related weight gain as an independent indication for renal replacement therapy in the intensive care units.

Attempts to identify specific therapies to reverse acute kidney injury (AKI) have been unsuccessful in the past; only modifying risk profile or addressing the underlying disease processes leading to AKI proved efficacious. The current thinking on recognizing AKI is compromised by a "kidney function percent-centered" viewpoint, a paradigm further reinforced by the emergence of serum creatinine-based automated glomerular filtration reporting over the last two decades. Such thinking is, however, grossly corrupted for AKI and poorly applicable in critically ill patients in general.

Bacterial Infections After Kidney Transplantation: A Single-Center Experience.

Background: Bacterial infections significantly affect graft loss and mortality after kidney transplantation (KT). We reviewed the frequencies, risk factors, and sources of bacterial infections after KT and their impact on graft and patient survivals.

Methods: The data of 154 kidney recipients who underwent transplantation from 2010 to 2015 were explored.

Questionnaire Development for the Measurement of Patients' Attitudes Toward Renal Transplantation.

Objective: The aim of this work was the exploration of chronic renal insufficiency patients' attitudes toward treatment, various motifs underlying their acceptance or refusal of kidney therapy, and understanding of their psychologic content. Examinations were carried out of chronic renal insufficiency patients' attitudes toward renal treatments, and a questionnaire suitable for its assessment was developed.

Methods: Suppositions of patients before and after renal transplantation were explored by means of semistructured interviews.

Clinical Utility of Potassium-Sparing Diuretics to Maintain Normal Serum Potassium in Peritoneal Dialysis Patients.

♦ BACKGROUND: Hypokalemia is a vexing problem in end-stage renal disease patients on peritoneal dialysis (PD), and oral potassium supplements (OPS) have limited palatability. Potassium-sparing diuretics (KSD) (spironolactone, amiloride) may be effective in these patients. ♦ METHODS: We performed a cross-sectional review of 75 current or past (vintage > 6 months) PD patients with regard to serum potassium (K+), OPS, and KSD utilization.

[Analysis of donor scoring systems in a single Hungarian transplant centre].

Introduction: To ease organ shortage many transplant centres developed different donor scoring systems, however, a general consensus among clinicians on the use of these systems does not still exist.

Aim: The aim of the authors was to analyse the effect of expanded criteria donor, deceased donor score and kidney donor risk index on postoperative kidney function and graft survival.

Method: Analysis of the characteristics of 138 kidney transplantations and 205 donors in a retrospective study of a five-year period.

[First outcomes, since being full member of Eurotransplant. A single center experience of cadaveric kidney transplantation].

Introduction: The first renal transplantation was completed in 1991 at the University of Debrecen. In 2013 Hungary joined Eurotransplant.

Aim: The authors retrospectively compared the trends.

Pregnancy management of women with kidney transplantation.

Women with renal disease, besides many dysfunctions, face increasing infertility and high-risk pregnancy due to uremia and changes of the hormonal functions. After renal transplantation, sexual dysfunction improves, providing the possibility of successful pregnancy for women of childbearing age. However, kidney transplanted patients are high-risk pregnant patients with increased maternal and fetal risks, and the graft also may be compromised during pregnancy; most studies report on several successive deliveries due to multidisciplinary team management.

Successful Peritoneal Dialysis in Large-Weight Subjects: Clinical Features and Comparisons with Normal-Weight Subjects.

Peritoneal dialysis (PD) obviates the need for temporary vascular access in end-stage renal disease; however, extremely heavy weight has been viewed as a relative contraindication to PD.We performed a cross-sectional review of multiple clinical and laboratory variables for 75 current or past PD patients (vintage > 6 months), comparing dialysis adequacy parameters for those with a large body weight (>100 kg, LWS group) and with a normal body weight (<75 kg, NWS group).In the LWS group (n = 17), mean weight was 117.

Minimization vs tailoring: Where do we stand with personalized immunosuppression during renal transplantation in 2015?

The introduction of novel immunosuppressive agents over the last two decades and the improvement of our diagnostic tools for early detection of antibody-mediated injury offer us an opportunity, if not a mandate, to better match the immunosuppression needs of the individual patients with side effects of the therapy. However, immunosuppressive regimens in the majority of programs remain mostly protocol-driven, with relatively little inter-program heterogeneity in certain areas of the world. Emerging data showing different outcomes with a particular immunosuppressive strategy in populations with varying immunological risks underscore a real potential for "personalized medicine" in renal transplantation.

Cardiovascular Screening and Management Among Kidney Transplant Candidates in Hungary.

Introduction: Cardiovascular disease is a major cause of morbidity and mortality in end-stage renal disease patients on dialysis and the most common cause of death in the immediate post-transplantation period. The aim of our study was to describe a novel approach of cardiovascular screening and management of dialysis patients evaluated for the transplant waiting list.

Methods: Twenty-eight patients with end-stage renal disease put on the waiting list between July 2013 and July 2014 were subjected to a prespecified cardiovascular screening protocol utilizing noninvasive and/or invasive tests.

Results of Expanded-Criteria Donor Kidneys: A Single-Center Experience in Hungary.
