Filter by:IgA plays a major role in mucosal and systemic immunity but retains mysterious and ambivalent aspects. They can thus, depending on the situation, prove to be capable of triggering either a protective inflammatory response or, on the contrary, anti-inflammatory and inducing tolerance. Similarly, and for reasons that remain very poorly understood, they can be involved in pathologies where the immune system is itself an aggressor of the body and responsible for immunopathological lesions. The investigator formulates the hypothesis that an inappropriate response of the mucosal immune system to one or more antigens leads to a synthesis of IgA of bad affinity favoring a deposit at the level of the mesangium. It seems important to verify this point by analyzing the IgA repertory of patients with N-IgA and comparing it to that of a control population.
The purpose of this study is to investigate if a diet high in plant protein improves kidney function in patients with kidney insufficiency and diabetes and/or hypertension and/or glomerulonephritis. The study is a non-blinded, randomized, controlled, cross-over-design with two intervention periods of each 14 days. Between the two interventions periods there is a washout period of 14 days. The participants are randomized to start with an individualized diet plan containing either high amounts of animal protein or high amounts of plant protein.
IgA nephropathy is the most common primary glomerulonephritis in the world. Because of the poor treatment effect in advanced patients, it is still the main cause of maintenance dialysis. Current immunosuppressive therapy is still controversial, especially to those progressive IgA nephropathy with eGFR<50ml/min. Leflunomide is widely used in the treatment of rheumatic diseases, such as rheumatoid arthritis and lupus nephritis, it's serum concentration will not be affected by renal function, and it also has antiviral effect. There are two randomized controlled trials and a retrospective study suggesting that leflunomide combined with glucocorticoids can effectively control urinary protein compared with glucocorticoids or conservative treatment, but these three studies are not specifically targeted at patients with estimated Glomerular Filtration Rate(eGFR) < 50ml/min. Investigators will perform a prospective, open-label, randomized, controlled trial to evaluate the efficacy and safety of leflunomide and low dose glucocorticoids therapy in progressive IgA nephropathy with eGFR<50ml/min
Glomerulonephritis (GN) generates an enormous individual and social economic burden. However, the therapeutic options are largely based on clinical and pathological parameters and the individual response to therapy or prognosis is uncertain. Recently, along with advances in molecular analysis and computational bioinformatics, genomic data from human renal biopsies could provide a strong foundation for the future of precision medicine in nephrology. In response to a request for applications by the Ministry of Health and Welfare of Korea for the creation of Clinical Research Registry, multi-center N network has been established for prospective cohort with kidney biopsy samples (KORNERSTONE). Through this Network the investigators hope to understand the fundamental biology of glomerulonephritis and aim to bank long-term observational data and corresponding biological data including genomic data from kidney tissues, and kidney pathologic data which is digitalized This database is archived to a web-based platform to access easily and further enrich for researchers.
Phase II Clinical Trial to Assess the dose-response and Efficacy of Umbilical Cord-derived Mesenchymal Stromal Cells (MSCs) in Severe Renal Systemic Lupus Erythematosus (SLE).
Primary membranous nephropathy (PMN), an autoimmune disease mostly associated with anti-phospholipase-A2-receptor (PLA2R) antibodies, is one of the most common causes of nephrotic syndrome in adults. In 30% to 40% of all cases, patients with PMN undergo spontaneous remission with conservative approaches. Corticosteroids, alkylating agents and calcineurin inhibitors are recommended treatment options in persistent disease activity despite supportive therapies. Nevertheless, patients with refractory disease constitute an important clinical aspect of PMN, and uncontrolled proteinuria may culminate in rapid progression to end-stage renal disease. In recent years, several studies demonstrated the efficacy of rituximab as a treatment option in patients with refractory PMN; however, data regarding daily clinical practice of this agent is still needed. Therefore, we conducted a study using our registry data to evaluate the efficacy and safety of rituximab in patients with refractory PMN.
The purpose of this study is to evaluate the effect of cemdisiran on proteinuria in adults with immunoglobulin A nephropathy (IgAN), who excrete >1 gram (gm) of protein per day despite standard of care, which includes treatment with angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARB). These participants are at high risk for progression of kidney disease, which can result in end-stage renal failure.
It has recently been described the presence of a urinary inflammatory signature in patients with cystinuria, the most common cause of renal lithiasis of genetical origin. These data are very innovative in this pathology but deserve further studies to establish the specificity of this inflammatory signature in patients with cystinuria compared to other nephropathies and other renal lithiasis diseases. Moreover, the effect of the usual treatment of cystinuria (namely urine alkalanization) on urinary inflammatory biomarkers deserves to be tested. The objectives of the present study are: i) To study the urinary inflammatory profile by mass spectrometry (a very efficient tool to detect and identify proteins) in patients with cystinuria and in patients with lithiasis of other origin and in patients with inflammatory renal disease ; ii) To study the potential effect of urine alkalinazation with potassium citrate (usual treatment according to European recommendations) on the inflammatory signature of patients with cystinuria. To this aim, urine of non treated cystinuric patients will be collected before treatement initiation and 3 months after the start of the alkalizing treatment.
The study is an open-label, two cohort non-randomized study evaluating the efficacy, safety, and pharmacokinetics of LNP023 in patients with C3G (Cohort A) and patients who have undergone kidney transplant and have C3G recurrence (Cohort B).
Functional and quantitative renal magnetic resonance imaging (MRI) has seen a number of recent advances, and techniques are now available that can generate quantitative imaging biomarkers with the potential to improve the management of kidney disease. However, there are knowledge gaps that must be addressed before renal MRI methods could be more widely adopted in clinical research and ultimately be transferred to clinical practice, including the biological basis of different MRI biomarkers, and how the application of these biomarkers will improve patient care. Among renal MRI techniques, renal diffusion weighted MRI (DWI) has been increasingly used in the last decade, showing high potential as a surrogate and monitoring biomarker for interstitial fibrosis in chronic kidney disease (CKD), as well as a surrogate biomarker for the inflammation in acute kidney diseases that may impact patient selection for renal biopsy in acute graft rejection. Within the ready-to-start ACH471-205 clinical trial, an Open-Label Phase 2 Proof-of-Concept Study in Patients with C3 Glomerulopathy (C3G) or Immune-Complex Membranoproliferative Glomerulonephritis (IC-MPGN) treated with ACH-0144471, aimed at evaluating the efficacy of 12 months of oral ACH-0144471 in patients with C3G or IC-MPGN, patients will undergo baseline and 12-month follow-up renal biopsies, and renal function will be assessed over time by estimated or measured (when available) glomerular filtration rate (GFR). Adding multi-parametric NCE-MRI to the examinations under the ACH471-205 study protocol will give the opportunity to elucidate, in a well-defined cohort of patients, the potential of NCE-MRI as biomarker of renal microstructure and functional change.
