Active clinical trials for "Renal Insufficiency"

Background: Parathyroid hormone (PTH) and 1,25-dihydroxy vitamin D (1,25-OHD) as well as mineral bone metabolism modulators like sclerostin are thought to play an important role in in diabetic patients with chronic renal failure. The present study aimed to analyse the levels of serum sclerostin before and after hemodialysis which is a primary element of treatment in such combined disease states. Methods: Serum sclerostin concentrations were measured using a commercially available enzyme-linked immunosorbent assay kit with 56 individuals who 14 chronic hemodialysis patients with diabetes, 14 chronic hemodialysis patients with non-diabetes and 28 healthy volunteers as a control group.

Little knowledge exist on the short and long-term ophthalmological effect of the dialysis. Some studies stated a variation of the thickness subfoveal choroidal before and after a session of dialyse as well as variations of the coat of optical fibers measured in OCT. The Optical Coherence Tomography angiography OCT is a not invasive imaging technique which is now a part of examinations of investigation in imaging of retina. This technique allows to study the retinal macula vascularization without injection of contrast agent and thus allows to deepen the knowledge in medical domains where the exploration was to limited because of the invasive character of the examinations. The hypothesis of this project is that hemodynamic change during the hemodialysis may lead fine variations of the retinal vascularization in the short-term (the day of the dialysis) but also in the longer term (over 1 year).

Evaluation of the pharmacokinetics (PK) of TBPM-PI-HBr in subjects with normal renal function, subjects with various degrees of renal insufficiency, and subjects with end-stage renal disease (ESRD) receiving hemodialysis (HD) therapy.

The objective of the study is to evaluate the effectiveness and safety of the reduced dose rivaroxaban (15 mg once daily) as compared to warfarin in non-valvular atrial fibrillation (NVAF) patients with renal dysfunction in routine clinical practice. The study has a retrospective design, and will be conducted in the US Truven Health MarketScan Commercial Claims and Medicare Supplemental Databases

Patient activation refers to patients' willingness and ability to make independent actions to manage their health and care and requires knowledge, skill and confidence. This study aims to explore activation levels of incident dialysis patients at start of dialysis and after 3 months of dialysis.

The recent discovery of extracellular vesicles (EV) as a mechanism of intercellular communication has made it possible to develop a new field of health research and could bring new information on the pathological mechanisms of renal diseases. Definition of physiologic and pathologic values of urinary extracellular vesicles (EVu) between healthy subjects and chronic kidney diseases (CKD) patients could be a new tool for follow up of renal diseases. EV are found in all biological fluids including urine, that's why they are increasingly analyzed in renal pathologies. The main objective of this study is to determine the physiological values and the pathological thresholds of EVu.

This observational study aims to compare long-acting darbepoetin alpha versus short-acting epoetin alpha erythropoietin-stimulating agents in Egyptian hemodialysis patients. The main questions aim to answer are: What are the effectiveness and safety of long- acting versus short-acting erythropoietin-stimulating agents in Egyptian hemodialysis patients? What is the cost-effectiveness of long- acting versus short-acting erythropoietin-stimulating agents in Egyptian hemodialysis patients? Participants will be divided into 2 groups; epoetin alfa (short-acting ESA), Eprex group, and darbepoetin alfa (long-acting ESA), Aranesp group for six month study period.

Postoperative renal function recovery is very important to value the operation quality after kidney transplantation. Dexmedetomidine is a selective alpha-2 agonist,enhances urine flow rate and perioperative renal function. Some animal experiments have revealed its beneficial effects against ischemia-reperfusion injury (IRI), our goal is therefore to investigate the effectiveness of a recipient treatment with Dexmedetomidine during operation at reducing Cystatin C level and enhancing renal function after kidney transplantation.

The purpose of this study is to assess if accumulation of anti-Xa activity occurs after repeated daily administration of prophylactic doses of tinzaparin in patients with severe chronic kidney disease (CKD) requiring thromboprophylaxis for non-surgical conditions. It is anticipated that tinzaparin used at a fixed dose for thromboprophylaxis in severe CKD patients (eGFR ≤ 30 ml/min /1.73 m2) at risk for venous thromboembolism (VTE) will not bioaccumulate at a significant level, meaning an increase of ≥ 20% of the anti-Xa mean level between day 2 or 3 and day 5.

The aim of the study is to evaluate a 3 months integrated multimodal therapeutic approach including exercise training program with ergocycle during dialysis sessions, oral nutritional supplementation, omega 3 and androgen, on effort tolerance and quality of life of under-nourish maintenance hemodialysis Chronic Kidney Disease (CKD) patient.
