Active clinical trials for "Kidney Failure, Chronic"

Primary endpoint: To evaluate predictive value of plasmatic levels of Neutrophil Gelatinase Associated Lipocalin (NGAL) to reveal acute kidney failure after cardiac surgery in patients with preoperative chronic kidney failure Secondary endpoint is to obtain threshold values of NGAL.

In this study, the recent trends in outcomes according to the dialysis modality in Korea since 2009, the effect of the use of peritoneal dialysis solutions containing icodextrin or high-glucose on various outcomes, the usefulness of 'PD first strategy', and the economic burden according to the dialysis modality will be investigated retrospectively using the Korean Health Insurance Review and Assessment Service (HIRA) database.

Patients with End Stage Kidney Disease (ESKD) require Renal Replacement Therapy (RRT) in order to survive, be it dialysis or kidney transplantation (KT). Of the two modalities, KT has been associated with better quality of life (QOL) [1-3], reduced morbidity and mortality[4, 5], and reduced healthcare costs[6]. Studies in the US have shown that patients receiving tailored transplant education were more likely to complete the transplant evaluation [9, 14, 15]. For instance, patients receiving the Explore Transplant (ET) education program designed by Dr. Waterman, were more knowledgeable about KT and more likely to complete KT evaluation than control patients. Currently, there is a lack of standardized KT education in Ontario. Traditional approaches have been insufficient in providing the necessary education and information to enable patients to make an informed decision about their care. To address this issue, the study will assess the impact of kidney transplant related education using the Explore Transplant Ontario (ETO) education program on kidney transplant-related knowledge and on readiness to consider KT, readiness to consider living donor KT, and wait list/referral rates in patients undergoing maintenance hemodialysis. In order to comprehensively measure this impact, 5 variables will be explored. Readiness to consider DDKT Readiness to consider LDKT KT related knowledge in patients Proportion of patients waitlisted or undergoing KT workup at 6 and 12 months after administration of ETO Proportion of patients who have identified at least one potential living donor at 6 and 12 months after administration of ETO The hypotheses are as follows: Readiness to consider DDKT will be higher in the "intervention" group compared to the "control" group at follow up. Readiness to consider LDKT will be higher in the "intervention" group compared to the "control" group at follow up. The KT related knowledge of the patients will be higher in the "intervention" group compared to the "control" group at follow up. The proportion of patients waitlisted or undergoing KT workup at 6 and 12 month after the KT education will be higher in the "intervention" group compared to the "control" group. The proportion of patients who have at least one potential living donor at 6 and 12 month after the KT education will be higher in the "intervention" group compared to the "control" group.

the study aims to determine rate of mortality and morbidity after total hip replacement in patients with chronic kidney diseases and incidence of periprosthetic joint infection in these patients.

The project will be structured in 3 main parts: Effect of sera of ESRD patients on HD using Theranova dialyzer on high-Pi induced vascular calcification in an in vitro model of rat VSMCs. Effect of sera of ESRD patients on HD using Theranova dialyzer on oxidative stress pathways in an in vitro model of rat VSMCs vascular calcification. Study of RNA sequencing, transcriptome analysis gene expression of time course high-P challenged VSMCs studying the effect of sera of ESRD patients on HD using Theranova dialyzer

The purpose of this study is to examined the effect of malnutrition and/or inflammation on atherosclerosis and prognosis in hemodialysis.

In summary, the researchers want to construct a longitudinal data bank using voluntary health examination participants. Researchers in the National Taiwan University Hospital (NTUH) campus can utilize these data to clarify the effects of several genetic and environmental factors on various common diseases in Taiwan in the future.

This study evaluates the relationship between Ambulatory Aortic and Branchial blood pressure vs Office blood pressure measurements with the changes in arterial stiffness indices, in long-term Peritoneal Dialysis (PD) patients. These parameters will be monitored both cross-sectionally at the start of the study and prospectively over a 6 month period.

Chronically dialyzed patients and kidney transplant recipients have been identified as particularly vulnerable to SARS-CoV-2 infection due to unavoidable exposure. They have also high rates of comorbid conditions and have varying degrees of immunosuppression, which puts them at risk of developing very severe forms of COVID-19 disease with fatality rates varying from 16% to 32%. In such circumstances vaccination is the only chance to improve their extremely poor prognosis. There is very little published data on the response to vaccination in dialyzed patients and kidney transplant recipients so far. No data are available on the efficacy of vaccines against COVID-19 in patients treated with peritoneal dialysis (PD). Furthermore, given the fact that disturbances of acquired immunity in dialyzed patients are many and diverse it is uncertain whether vaccinating against SARS CoV-2 in these population will result in sufficient immune response and, by consequence, protection against infection. Registration studies on the basis of which population vaccinations are actually conducted were performed only in the general population. There were no dialyzed patients and kidney transplant recipients in the study groups, so these patients are vaccinated with doses and schedules for people without chronic kidney disease. It is not known whether vaccination under such standard schedule produces a sufficient immune response in them and how long it lasts. That's why the aim of this study is to evaluate the humoral and cellular immune response after mRNA vaccine against COVID-19 with which patients treated with renal replacement therapy are vaccinated in Poland. It will be a prospective, observational controlled study conducted in patients treated with renal replacement therapy (hemodialyzed subjects, patients treated with peritoneal dialysis and kidney transplant recipients) vaccinated with mRNA vaccine against COVID-19 according to common rules and manufactures recommendations.The control group will be made up of sex and age matched people without chronic kidney disease.The first goal of the study is to analyze seroconversion rate and titer magnitude of neutralizing IgG and IgA antibodies directed against spike (s) SARS-CoV-2 antigen after the first and the second dose of mRNA vaccine as well as after 3, 6, 9, 12 months after vaccination. The second goal is to evaluate the cellular immune response tested using the ELISPOT method at the same time points as above.The immune response will be compared to patients without chronic kidney disease as well as between hemodialysis, peritoneal dialysis patients and kidney transplant recipients.

Majority of patients with hypertension have primary hypertension (without an underlying cause). Primary aldosteronism (PA) is the most common cause of secondary hypertension, and can be found in 5-10% of patients locally. PA is caused by excessive release of a hormone (aldosterone) from the adrenal glands, which can be unilateral (one gland) or bilateral (both glands). It has been shown that excess aldosterone has other harmful effects in addition to hypertension, such as directly affecting the heart, blood vessels, kidneys, leading to increased cardiovascular morbidity and mortality. This is supported by studies showing reversal of these effects after treatment for PA. The investigators aim to assess the long-term cardiovascular, and renal outcomes of patients with PA, compared to patients with essential hypertension.
