Active clinical trials for "Kidney Failure, Chronic"

A retrospective cohort study was conducted in 66 end-stage renal disease patients who underwent high-efficiency hemodiafiltration technique in King Chulalongkorn Memorial Hospital between 2001-2013 to determine the survival rate as well as other long-term outcome.

Treatment of patients with end-stage renal disease and critical limb ischemia still poses challenges to vascular medicine due to limited survival, comorbidities and infrapopliteal involvement of arteriosclerosis in these patients. Most optimal vascular therapy mode has not been finally decided in these patients. Therefore retrospective analysis of patients receiving open surgical and endovascular revascularisation was performed.

Cell-mediated immunity (CMI) and in particular T cells play a critical role in the rejection of transplanted organs. Thus, in transplant recipients a life-long and individualized immunosuppressive medication is required to avoid graft rejection. However, a too weak suppression of CMI causes acute and chronic graft damage leading to transplant loss, whereas a too potent suppression of CMI supports opportunistic infections and reactivation of persistent viruses. One of the biggest challenges in the field of transplantation is to provide a personalized immunosuppressive and antiviral therapy based on reliable assessment and monitoring of CMI. This could lead to a reduction of graft rejections and virus reactivations in transplant recipients. With the development of both assays T-Track® CMV and T-Track® EBV, Lophius Biosciences GmbH has implemented its novel proprietary T-activation technology for an improved assessment of the functionality of CMI in cytomegalovirus (CMV)- and/or Epstein-Barr virus (EBV)-seropositive individuals. In contrast to other existing systems the Lophius assays open up the opportunity to characterize the functionality of CMI as an entire network. The planned clinical multicenter study aims to verify the suitability of the two assays for a reliable assessment of the functionality of CMI. Hemodialysis patients have been identified as an appropriate patient cohort for investigating the clinical sensitivity of the Lophius assays as these patients closely resemble kidney transplant recipients prior to an immunosuppressive therapy. The determination of the functional CMI in the course of an immunosuppressive treatment may in future enable physicians to optimize the individual immunosuppressive and antiviral therapy in transplant recipients to reduce the risk of rejection as well as virus reactivations and associated diseases.

Managing fluid status is a complex but fundamental part of the clinical care of people receiving haemodialysis (HD). Day-to-day fluid management is usually based on the concept of 'target weight' - the weight used to determine how much fluid should be removed during each dialysis session. However, the focus of this approach is usually on avoiding fluid overload (hypervolaemia), since this is associated with a higher incidence of cardiovascular and pulmonary events, in addition to increased morbidity and morbidity. As a consequence, a significant proportion of people on maintenance HD spend a great deal of time in a dehydrated state. Although dehydration is known to be associated with a number of unwanted consequences (e.g. headaches, severe fatigue, impaired cognitive and physiological function), there has been little research focusing on the impact dehydration has on the physical and psychosocial well-being of this patient group. Considering the short life expectancy of individuals with end-stage renal disease (ESRD) reliant on maintenance HD, particularly those who are unable to receive a renal transplant, we should be focused on improving their function and quality of life (QoL). Key issues that need addressing prior to developing interventions in this cohort are 1) investigating the best and alternative measures to assess hydration status and 2) documenting the biopsychosocial impact of typical target weight driven HD in a well-designed study.

This study aims to determine the extent to which pre-existing long-term conditions are associated with survival following a heart attack (acute myocardial infarction) using observational data from the UK's national heart attack register.

The patient subjected to hemodialysis has a low physical capacity due to being advanced in years and the complexity of the process, which is encouraged by family members and caregivers who lead them to a total dependence. The Intradialytic physical exercise is presented as an alternative to counteract this functional deterioration of patients with terminal chronic kidney failure.

Patients undergoing chronic dialysis are at a substantially increased risk of cardiac death. The reasons for this excess cardiovascular mortality are only partly understood. Classical complicated artherosclerotic disease does not appear to be the primary cause of cardiac death in chronic dialysis patients. In fact, the predictive potential of classic cardiovascular risk factors such as hypertension, obesity and hyperlipidemia appears to be reduced in dialysis. In contrast, in a series of pilot studies we found cardiac biomarkers to adequately reflect dialysis induced myocardial stunning, progressive cardiovascular disease, and the risk of death. To extend and corroborate these results, we are planning a large, prospective, observational study enrolling unselected hemo- and peritoneal dialysis patients. The proposed study, its power calculation and hypotheses are based on our pilot studies

The prevalence of chronic kidney injury (CKD) following cardiac surgery during childhood is not known, but there is evidence of CKD in young adults. In the present study assumption is made that CKD can already by diagnosed in patients at or just before adolescence, and the aim is calculate its prevalence according to the KDIGO criteria by a cross-sectional study, which will enroll patients aged 10 to 15 years. The second hypothesis is that events occurring peri-operatively during initial surgery or during follow-up could by chart review and regression analysis.

The aim of this study is to assess whether patients receiving current recommendations of an adequate dialysis dose by Kt adjusted for body surface area improved survival at 24 months compared to those who do not get it, as well as assess whether patients receiving a dose greater obtain more benefit.

In this study, we studied lipoprotein abnormalities-related variables as risk factors for the development of cardiovascular disease in patients on renal replacement therapies.We studied 96 dialyzed patients, 62 males and 34 females, on mean age 62.1 years old and 24 healthy controls.We concluded that metabolic acidosis activating the inflammation and lipoprotein oxidation influences the dyslipidemia and cardiovascular morbidity of patients on renal replacement therapies.Dialysis adequacy was positively associated to cardioprotective HDL.Peritoneal dialysis holds a better acidosis level and lower oxidized lipids than hemodialysis modalities.
