Filter by:Radical nephrectomy is a common operation for the treatment of renal cell carcinoma. However, acute kidney injury frequently occurs after surgery. And the occurrence of acute kidney injury is associated with an increased risk of chronic kidney disease. Intraoperative hypotension is identified as an important risk factor of postoperative acute kidney injury. Preliminary studies showed that goal-directed hemodynamic management may reduce kidney injury after surgery but requires further demonstration. We hypothesized that goal-directed hemodynamic management combining hydration, inotropes, and forced diuresis to maintain pulse pressure variation <9%, mean arterial pressure ≥85 mmHg, and urine flow rate >200 ml/h (3ml/kg/h) may reduce the incidence of acute kidney injury and improve long-term renal outcome after radical nephrectomy. The purpose of this study is to investigate the effect of goal-directed hemodynamic management on the occurrence of acute and persistent kidney injury in patients following radical nephrectomy.
This is a multi-center, randomized, double-blind, placebo-controlled study. About 310 maintenance hemodialysis patients with moderate or above chronic kidney disease-associated pruritus are planned to be enrolled. They will randomized into the treatment group (HSK21542, 0.3 μg/kg) and the control group (placebo) at a 1:1 ratio.
Chronic kidney disease (CKD) consists of kidney damage, with a consequent progressive and irreversible loss of kidney function. In the early stages of the disease, there is already a reduction in circulating levels of α-klotho protein, which is related to worsening renal function. Therapeutic strategies that increase serum α-klotho levels can be of great value in the treatment of CKD. Electrical stimulation contributes to the reduction of reactive oxygen species, DNA damage and improves the efficiency rate of dialysis, suggesting a systemic effect in patients with end-stage CKD. The aim of this study is to evaluate the effects of bioelectric stimulation on renal function and physical capacity in patients with CKD. For this, patients will be randomized into bioelectric stimulation or a control group. Bioelectric stimulation will be performed three times a week for eight weeks. The control group will only be evaluated and re-evaluated. The following pre-and post-intervention assessments will be performed: analysis of the plasma content of α-Klotho and soluble creatinine to assess renal function, six-minute walk test to assess functional capacity; dosage of interleukins and tumor necrosis factor to analyze the inflammatory profile; sit and stand test with 10 repetitions and load cell dynamometry to assess lower limb muscle strength and application of the EuroQoL-5D questionnaire for quality of life. Biochemical analyzes for renal function and inflammatory profile will also be performed after four weeks of follow-up.
The CAREPATH will conduct Technical Validation and Usability (TVU) study by involving ≥ 45 target end users (16 patients with MCI or mild dementia with their informal caregivers and 16 healthcare professionals from various disciplines) and Clinical Investigation (CI) study involving ≥ 200 patients (≥ 100 users to pilot the CAREPATH platform and ≥ 100 patients as reference cases). Both of these pilot studies will be coordinated in four European countries (Spain, Romania, Germany and UK) with diverse health and social care systems, ICT landscape/digital maturity of healthcare provision and dementia national programs, which will allow for strengthening the evidence base on health outcomes and efficiency gains. The CAREPATH outcomes can be summarized as: 1. An Integrated Care Platform that jointly addresses multimorbidity, dementia and diminished intrinsic capacity and optimally manages healthcare interventions for its users (patients, informal caregiver, healthcare providers, etc). 2. Technical Validation and Usability (TVU) study involving over 45 users and Clinical Investigation (CI) involving over 200 patients that will be conducted in four European countries (Spain, Romania, Germany and UK) during two years and mobilizing the other necessary actors, such as caregivers and healthcare professionals, for the validation of healthcare interventions. 3. Dementia / Multimorbidity Guidelines that will be conceived for best healthcare delivery. 4. Health Economics Impact Assessment for healthcare cost effectiveness and care provision equalities. The incremental cost-effectiveness and the incremental cost-utility ratio would allow revealing the incremental cost (or the potential savings) per unit of benefit of switching from usual care to CAREPATH-an integrated patient-centred approach- in multimorbid elderly patients with dementia, and therefore, to determinate whether the CAREPATH approach would be considered as a cost-effective alternative.

Obesity is at risk for the development of chronic kidney disease but the involved mechanisms are not known (Navarro et al. 2015). Establishing the link between obesity and kidney damage is difficult. Indeed, kidney function measurement lacks precision in obese people (Lemoine et al. 2014) and requires expensive methods such as measurement of 99mTc-DTPA clearance. Biopsies are too invasive for the detection of emerging kidney damage or for the following of the kidney function. Therefore new tools are required for the early identification of at risk individuals for the kidney damage complication. Mesenchymal stem cells may represent such a relevant tool. These cells are present in a large number of organs, including kidney (Costa et al. 2020). In addition to be differentiated cells progenitors (Dominici et al. 2006), they also support immunosuppressive, anti-fibrotic and pro-angiogenic functions that have been used for the treatment of kidney fibrosis (Usunier et al. 2014). Therefore, mesenchymal stem cells contribute to tissue homeostasis and their alterations may reflect organ dysfunctions. Indeed, mesenchymal stem cells from obese adipose tissue lose their immunosuppressive (Serena et al. 2016) and differentiation (Gustafson et al. 2009) functions and contribute to fibrosis (Keophiphath et al. 2009) and inflammation (Lee et al. 2010; Gustafson, Nerstedt, et Smith 2019). It is thus probable that kidney dysfunctions are associated with functional alterations of kidney mesenchymal stem cells. The collection of mesenchymal stem cells from kidney can easily be performed from urine and next cultivated for amplification. They are called urine stem cells (USC). From our experience with obese mouse adipose stem cells, we observed that functional changes of stem cells preceded adipose tissue dysfunctions. Functional signatures of mesenchymal stem cells are thus representative of changes occuring in the function of the tissue notably in answer to obesity. These features could be used to identify obese people presenting ongoing alterations of kidney function, before clinical manifestations of kidney dysfunction. Because kidney mesenchymal stem cells are easy to isolate from urine, their collection is compatible with the follow up of patients and can be applied to a large number of individuals, including the younger. USC could represent a valuable tool to detect progression towards kidney damage. In this project we plan to analyse USC alterations induced by obesity and to identify signatures associated with the progression towards kidney damage and type 2 diabetes. The goal is to evaluate USC as potential marker for the non invasive monitoring of patients in answer to a need that is not achieved by the present available approaches.
The study is being conducted to evaluate the efficacy, and safety of Paricalcitol for secondary hyperparathyroidism with stage 3 and stage 4 chronic kidney disease in adults.
Peritoneal dialysis is an effective renal replacement therapy with higher quality of life and lower treatment cost than hemodialysis.However, the application rate of peritoneal dialysis is much lower than that of hemodialysis. One of the reasons is that patients need to complete fluid changing operation independently, which is especially challenging for elderly and frail patients. Assisted peritoneal dialysis can help patients with independent dialysis disorders to complete dialysis. Currently, there is a lack of standard tools to assess patients' ability to conduct independent dialysis and to determine whether assisted dialysis is needed. Moreover, routine assessment is arranged after the training of dialysis operation, which leads to some patients giving up the procedure at an early stage, resulting in a low selection rate of the procedure.The purpose of this study was to investigate the effect of using a standard scale to evaluate the ability to perform abdominal dialysis in patients with stage 5 chronic kidney disease (CKD) before deciding on dialysis modality.
