Filter by:This study evaluates the effect of high-flux hemodialysis compared to hemodiafiltration on small and moderate molecule substances clearance. Meanwhile, this study evaluates the effect of high-flux hemodialysis compared to hemodiafiltration on cardiac function. In this self matching study, participants will receive high-flux hemodialysis compared to hemodiafiltration.
To investigate the feasibility of calcium dobesilate in the treatment of microvascular injury provides new ideas and theoretical basis for the prevention and treatment of chronic renal failure.
Patients who start haemodialysis usually retain some natural kidney function for months or years after starting dialysis. Even a small amount of this natural kidney function can be helpful in reducing the need for dietary and fluid restriction. There is also good evidence that retaining a small amount of natural kidney function may provide a survival benefit for patients on dialysis. Most patients who commence haemodialysis start three times per week for 3.5-4 hours per session, irrespective of the amount of natural kidney function they may have. An alternative approach used in some kidney units is to take account of the natural kidney function in prescribing the amount of dialysis. This may allow patients to start treatment needing to spend less time on dialysis or even to start just twice weekly. The amount of dialysis can be adjusted over time as natural kidney function declines. This is called "incremental haemodialysis". Both of these approaches are considered to be standard care although it is not known which approach is more beneficial to patients. There are some suggestions that the frequency of dialysis may influence the rate of decline of natural kidney function but this need to be tested in a large randomised study. To inform the design of such a study, a smaller scale feasibility study is required. We intend to randomise fifty new starters on haemodialysis with adequate natural kidney function into two groups - a group who will have dialysis prescribed in the standard fashion - three times weekly for 3.5-4 hours per session or a group who will have an incremental start beginning with twice weekly treatment. We will investigate how many patients have sufficient natural kidney function to be eligible, whether patients are willing to participate and continue in the study, compare the rate of loss of kidney function between groups, and ascertain whether this individualised dialysis approach is less intrusive to patients. The results will be used to design a larger definitive study.
identification of the factors that affect the outcome of arteriovenous fistula in chronic renal failure patients that newly established regular dialysis in Assiut Governorate 1. To study the factors that influence the outcome of AVF 2. To evaluate the vascular complications of AVF as occlusion, rupture, aneurysmal dilation and hand ischemia
Diabetes kidney disease is a leading cause for end stage renal disease in the western world. To date no treatment that can reverse renal damage exists. Chronic hypoxia is one of the major key insults affecting the diabetic kidney, and many of the new treatments under study focus on it's consequences, but no treatment can improve the hypoxia as both increased renal perfusion and decreased renal perfusion may be associated with it's worsening. Hyperbaric oxygen therapy (HBOT) can improve renal hypoxia by increasing partial pressure of dissolved (non-hemoglobin-bound) oxygen without affecting it's demand. HBOT also recruits tissue and peripheral progenitors and supplies the optimal environment crucial for their proliferation and for tissue repair. Hyperbaric oxygen treatment was known for years as an effective treatment for diabetic ulcers. Recent trials have shown great impact on brain lesions (in diabetic and non-diabetic patients) it is now the time to evaluate the effect of HBOT on the diabetic kidney.
Acute renal dysfunction associated with cardiac surgery (DRA-ACC) in our hospital population affects 39% of patients, being an important cause of morbidity and mortality, increasing the need for dialysis and assuming a prolongation of stay in the unit of intensive care, as well as an increase in the economic cost. In this sense, extracorporeal circulation (CPB) is a clear aggression for renal function due to multiple effects, not entirely known. Human albumin is sometimes used as part of the priming of the CEC circuit in variable concentration according to published centers and studies, demonstrating benefits on the maintenance of plasma oncotic pressure during the period of ECC, as well as other effects that can protect renal function during this period of renal injury. Despite the use of albumin in the ECC priming both in Spain and in other countries, there are currently no published studies demonstrating the effect of albumin on renal function administered during CPB in cardiac surgery during the postoperative period. with a high incidence of kidney injury, although there are current studies that confirm a decrease in the incidence of kidney injury in patients with hypoalbuminemia and who undergo heart surgery without extracorporeal circulation. The hypothesis of this study is based on the potential protective effect of albumin on renal function in patients undergoing heart surgery under CPB, in which there is a high incidence of postoperative hypoalbuminemia. This study aims to obtain information about the effect that albumin can have in this population of patients with a high incidence of acute renal dysfunction, and if this benefit exists, whether it is significant or not to justify its systematic use.
The daily energy expenditure of patients treated with peritoneal dialysis could be increased compared to the general population and promote the development of a state of undernutrition. Conversely, the absorption of glucose by transperitoneal route could contribute to the occurrence of a metabolic syndrome. The main objective is to compare DE and its variations according to the conditions (rest, sleep, meals, physical activity) in patients treated with automated DP compared to controls, in a calorimetric chamber.
The aim of the study is to determine the effect of functional exercise and training counseling by kinesiotherapist in addition to the basic exercise program of cycling during dialysis on physical performance of dialysis patients.
The main purpose of our study is to investigate whether haemodialysis itself affects the efficacy of antiplatelet drugs and the effects of two different types of dialysis membranes (polysulfone membranes and polyamide membranes) on antiplatelet efficacy. A total of 60 patients with ESRD and under dual-antiplatelet treatmen for at least 5 days will be enrolled and divided into the Clopidogrel group (clopidogrel 75mg qd;aspirin 100mg qd, n=30) and the Ticagrelor group (ticagrelor 90mg bid; aspirin 100mg qd, n=30). All included patients will receive haemodialysis by two different types of dialysis membrane.Platelet aggregation of venous blood from all patients will be detected by LTA and VerifyNow immediately before and after two times of haemodialysis.
