Active clinical trials for "Kidney Diseases"

Fermented papaya preparation has been reported to bind and neutralize reactive oxygen species as well as iron. Patients undergoing hemodialysis are generally on iron overload status due to their inability to use iron storage adequately. The aim of this study is to evaluate the effect of FPP on the iron status of these patients.

The purpose of this study is to determine whether microwave ablation is more effective in the treatment of simple renal cysts than conventional laparoscopic decortication.

Idiopathic membranous nephropathy (IMN) remains a common cause of the nephrotic syndrome in adults and one of the leading known causes of end-stage renal disease. Identification of circulating autoantigens provide potential biomarkers for diagnosis and therapy of idiopathic membranous nephropathy. M-type phospholipase A2 receptor (PLA2R) and Thrombospondin type-I domain-containing 7A (THSD7A) were identified as the target antigen in membranous nephropathy with high specificity and the concentration of serum anti-PLA2R antibody and anti-TSHD7A antibody were helpful for predicting disease activity. In our prospective cohort study, hospitalized patients diagnosed as IMN are prospectively studied. Circulating anti-PLA2R antibody and anti-THSD7A antibodies were recently screened by using enzyme-linked sorbent assay(ELISA). This study aims to analyse the difference of clinicopathological characteristics for different concentrations of serum anti PLA2R antibody and anti TSHD7A antibody, and analyze the association between baseline concentrations of serum antibody and disease activity. This study also explored the prediction effects of serum antibody concentrations with different types of therapeutic regimen in IMN and compare the curative effects of different types of therapeutic regimen in different serum antibody concentrations.

The pathophysiology of diabetes is multifactorial. Beyond genetic susceptibility loci, a lot of acquired risk factors are involved in the development and progression of the disease. Chronic complications of diabetes can be divided into vascular and nonvascular. The risk of developing complications increases with the duration of hyperglycemia, and usually become apparent in the second decade of hyperglycemia. Vascular complications are further subdivided into microvascular (retinopathy, nephropathy and neuropathy) and macrovascular (coronary artery disease, peripheral arterial disease, cerebrovascular disease). It is estimated that the annual decline of estimated glomerular filtration rate (eGFR) in diabetic adults is about 2.1-2.7 ml/min. While there is consolidated evidence about the use of aspirin (ASA) for secondary prevention in diabetic patients, there is no consensus on the use in primary prevention; the use of ASA in these patients is at physician discretion. ASA is an effective antithrombotic agent that inhibits the production of thromboxane (Tx) A2 and other prostaglandins by blocking cyclooxygenase (COX). In patients treated with aspirin, serum TxB₂ level is the most reliable in vivo indicator of COX-1 inhibition than TxA2, due to its short half-life and artifacts associated with platelet activation ex vivo. COX are present in the kidney in the macula densa, in the medulla and in the interstitium. Experimental animals models have demonstrated that COX are involved in regulation of renal blood flow. In particular, in a murine animal model, after the administration of COX inhibitors such as aspirin and celecoxib, it was observed an improvement in renal plasma flow and eGFR, suggesting a role for Tx in the progression of renal damage However, data on the relationship between aspirin and renal function in humans are scarce. In a recent work lead on a large cohort of 800 patients with non-valvular atrial fibrillation, ASA use was associated with a reduced progression of eGFR <45 ml/min during 2 years of follow-up. Furthermore, basal levels of urinary excretion of TxB2, correlated inversely with the use of aspirin and with the decrease of eGFR at follow-up. The aim of the study is to evaluate the decline in renal function in diabetic patients treated with low-dose aspirin (100 mg/day) vs. untreated diabetic patients.

To evaluate the efficacy and safety of ferric citrate tablet in the control of serum phosphorus levels in patients with chronic kidney disease undergoing hemodialysis.

This clinical trial is an open, single-center, phase 1 clinical trial to evaluate the safety of allogeneic bone marrow-derived mesenchymal stem cell injection in patients with chronic kidney disease. The purpose is to evaluate the safety for 12 months after administration of Cellgram-CKD 3 times in 10 patients with chronic kidney disease.

This study aims to study SGLT2 inhibitors in patients who are undergoing haemodialysis for end stage renal disease and established ASCVD, to examine the safety and clinical outcomes, consisting of a composite of non-fatal stroke, non-fatal myocardial infarction, or cardiovascular death as the primary outcome. The key secondary composite outcome was all cause death or hospitalization for unstable angina.

The study is focused on the possible improving effect of N-acetylcysteine on nephropathy of type-2 diabetic patients. Study design: Prospective clinical based study. The aim of this work is to study the effect of N-acetylcysteine (NAC) on proteinuria and on the serum level of lipoprotein a (LPa) in diabetes induced nephropathy in type-2 diabetic patients.

Diabetic nephropathy (DN) is one of the most serious complications of diabetes and the leading cause of end-stage chronic kidney disease. DN is a refractory disease with low awareness, high incidence, and high disability. The incidence of DN can reach 30 to 40% after 20 years of diabetes, of which 5~10% of patients will progress to end-stage renal disease, and epidemiological surveys predict that by 2030, DN will become the seventh leading cause of death in the world. Currently, there are no effective drugs for treating DN. This clinical trial is to inspect the safety and efficiency of human umbilical cord mesenchymal stem cells (UC-MSCs) therapy for patients with DN.

Theranova is a novel medium cut-off dialyzer and has better performance for removal of middle molecules compared to conventional hemodialysis. The study investigates the effect of Theranova dialzyer on preserving residual renal function in the incident hemodialysis pateitns compared to high-flux dialzyer. The primary endpoint is change of glomerular filtration rate, calculated using creatinine and urea clearance. The secondary endpoints are glomerular filtration rate, daily urine volume, serum middle molecule concentrations, hospitalization, mortality, and patient reporeted outcomes.
