Kidney diseases related to the immune system include, nephrotic syndrome, glomerulonephritis, membranous nephropathy, lupus nephritis, and nephritis associated with connective tissue disorders. This study will allow researchers to admit and follow patients suffering from autoimmune diseases of the kidney. It will attempt to provide information about the causes and specific abnormalities associated with autoimmune kidney disease. Patients with kidney disease as a result of their immune system, and patients with diseases of the immune system who may later develop kidney disease, will be potential subjects for this study. Patients will undergo a history and physical examination, and standard laboratory test to more closely understand the causes, signs, symptoms, and responses to medication of these diseases. Based on these evaluations the patients may qualify as candidates for other experimental studies. At any time these patients may be asked to submit blood or urine samples for further research....
NCT00977977
Background: * Membranous nephropathy is associated with damage to the walls of the glomeruli, the small blood vessels in the kidneys that filter waste products from the blood. This damage causes leakage of blood proteins into the urine and is associated with low blood protein levels, high blood cholesterol values, and swelling of the legs. These problems can decrease or go away without treatment in about 25 percent of patients, but if they persist, some patients may experience impaired (or loss of) kidney function, blood vessel and heart disease, and a risk of forming blood clots in veins. * Kidney biopsies that show that antibodies have been deposited along the glomeruli suggest that specialized cells of the immune system, called B and T cells, are causing damage to the kidneys through their increased activity. To suppress the action of B and T cells and to decrease the harmful deposits in the kidneys, drug treatments are required. * Patients with membranous nephropathy are often treated with immunosuppressive drugs such as cyclosporine or cytoxan plus steroids that attempt to reduce or suppress the activity of the immune system, decrease antibody production, and reduce antibody deposits in the kidney. However, not everyone responds to these medications and the kidney disease can return in some patients when the drugs are stopped. Also, there are side effects associated with long term usage of these medications. Rituximab, a different immunosuppressant, has also been used for this purpose. Although cyclosporine and Rituximab have been used separately, they have not been tried in combination as a possible treatment for membranous nephropathy. Objectives: \- To determine the safety and effectiveness of combining rituximab and cyclosporine to treat membranous nephropathy. Eligibility: \- Individuals 18 years of age and older who have been diagnosed with membranous nephropathy based on a kidney biopsy done within the preceding 24 months, and who have had excess levels of protein in the urine for at least 6 months based on urine and blood tests. Design: * Potential participants will be screened with an initial clinic evaluation and full medical history. * Before the treatment, there will be a run-in period that will last up to 2 months. During this time, participants will be placed on a blood pressure lowering medication and will not take any other immunosuppressant medications. * Participants will visit the NIH clinical center for a baseline evaluation, four intravenous infusions of rituximab, and also at 1- to 6-month intervals throughout the study. * Active treatment period will involve a 6-month course of cyclosporine and a total of four doses of rituximab. Participants will take cyclosporine tablets twice daily, and have two infusions of rituximab given 2 weeks apart, After 6 months, the cyclosporine dose will slowly be decreased over several weeks and then completely discontinued. Participants will then receive another course (two doses 2 weeks apart) of rituximab, depending on results of blood work. * Participants will have frequent blood and urine tests performed to monitor the results of treatment and reduce the chance of side effects.
NCT07516964
Nephrotic syndrome is a kidney condition that mainly affects children and is characterized by high levels of protein in the urine, low levels of protein in the blood, and swelling. While many children respond well to steroid treatment, a large proportion experience relapses or become dependent on therapy. In some cases, the disease does not respond to standard treatments and may progress to chronic kidney disease. Recent research suggests that, in addition to genetic factors, immune system mechanisms may play a key role in the development and progression of nephrotic syndrome. In particular, some patients produce autoantibodies against nephrin, an essential protein of the kidney filtration barrier. These autoantibodies may be associated with disease activity and treatment response. The aim of this study is to investigate the presence of anti-nephrin autoantibodies in children with nephrotic syndrome and to better understand their role in disease mechanisms and clinical outcomes.The study will also explore the presence of other autoantibodies targeting components of the glomerular filtration barrier. The study will use advanced laboratory techniques, including blood tests and detailed analysis of kidney biopsy samples, to identify these antibodies and their relationship with kidney structure and function. By integrating laboratory findings with clinical data, this study aims to improve the understanding of nephrotic syndrome and support the development of more personalized diagnostic and therapeutic strategies, with the goal of improving patient outcomes and reducing unnecessary or ineffective treatments.
NCT04456816
This study is an exploratory, randomized, double-blind, multicenter, placebo-controlled study with repeated doses of AP1189.

NCT03949855
The primary objective of this study is to evaluate the effectiveness of belimumab and intravenous rituximab co-administration at inducing a complete or partial remission (CR or PR) compared to rituximab alone in participants with primary membranous nephropathy. Background: Primary membranous nephropathy (MN) is among the most common causes of nephrotic syndrome in adults. MN affects individuals of all ages and races. The peak incidence of MN is in the fifth decade of life. Primary MN is recognized to be an autoimmune disease, a disease where the body's own immune system causes damage to kidneys. This damage can cause the loss of too much protein in the urine. Drugs used to treat MN aim to reduce the attack by one's own immune system on the kidneys by blocking inflammation and reducing the immune system's function. These drugs can have serious side effects and often do not cure the disease. There is a need for new treatments for MN that are better at improving the disease while reducing fewer treatment associated side effects. In this study, researchers will evaluate if treatment with a combination of two different drugs, belimumab and rituximab, is effective at blocking the immune attacks on the kidney compared to rituximab alone. Rituximab works by decreasing a type of immune cell, called B cells. B cells are known to have a role in MN. Once these cells are removed, disease may become less active or even inactive. However, after stopping treatment, the body will make new B cells which may cause disease to become active again. Belimumab works by decreasing the new B cells produced by the body and, may even change the type of new B cells subsequently produced. Belimumab is approved by the US Food and Drug Administration (FDA) to treat systemic lupus erythematosus (also referred to as lupus or SLE). Rituximab is approved by the FDA to treat some types of cancer, rheumatoid arthritis, and vasculitis. Neither rituximab nor belimumab is approved by the FDA to treat MN. Treatment with a combination of belimumab and rituximab has not been studied in individuals with MN, but has been tested in other autoimmune diseases, including lupus nephritis and Sjögren's syndrome.

In a monocentric, later multicentric prospective approach the FOrMe registry (The German Focal Segmental Glomerulosclerosis and Minimal Change Disease Registry) aims to generate a longitudinal cohort of 150 pediatric cases of idiopathic nephrotic syndrome and 350 adult cases of biopsy-proven Minimal Change Disease (MCD) or Focal and Segmental Glomerular Sclerosis (FSGS) over 10 years. The registry will provide a repository for biomaterials such as blood samples, DNA, urine, feces, and tissue biopsies that will be accessible to collaborators to facilitate future research on pathogenesis, diagnostics, and treatment.
NCT04759274
This purpose of this study is to determine the effectiveness of a mobile phone application in helping to control body swelling in patients with kidney problems. The application will help in the day to day adjustments in diuretic medication dosing. Participants in this study will have an application loaded on to their mobile phone by the study team and be taught how to use it over a 2 hour visit. Participants will need to check their blood pressure and weight daily and enter this information into the mobile phone application every day. Participants will need to follow daily instructions in their medication dosing provided by the application. There will be periodic blood testing. This will happen at 2 weeks, 90 days, and up to 4 other times if necessary. At the end of the study there is a 2 hour study visit during which participants will answer a survey. The total length of the study is 90 days.
NCT06797609
This observational study relates to subjects with primary membranous nephropathy enrolled in the ongoing PEPTIDE, MONET, and ORION clinical trials performed and coordinated by IRFMN (NCT04095156, NCT04893096, and NCT05050214 respectively) to assess the efficacy of anti-CD20 or anti-CD38 monoclonal antibodies (rituximab and obinutuzumab) or anti-CD38 monoclonal antibody (felzartamab) therapy in inducing remission of NS during 1-year follow-up. Serum samples for measurement of Cystatin C (Cys-C), a low-molecular-weight protein, will be identified among those of the patients with NS who provided consent to store their samples at the Centro di Ricerche Cliniche per le Malattie Rare "Aldo e Cele Daccò", Ranica (BG) in the certified biobank UNI EN ISO 9001:2015; certification n° 6121 - Centro di Risorse Biologiche Mario Negri - Biobanca Malattie Rare e Malattie Renali (CRB). Measured GFR by plasma clearance of iohexol, as well as serum Cr or CKD EPI values in addition to the hematochemical and urinary parameters, are already available because measured during the studies in which the subjects were enrolled. Serum samples will be tested by Laboratorio Analisi Chimico-Cliniche Area Specialistica del Settore Autoimmunità ASST Papa Giovanni XXIII, Bergamo.

NCT06607991
This exploratory clinical trial aims to evaluate the efficacy and safety of Blinatumomab in treating children with calcineurin inhibitor (CNI)-resistant or multidrug-resistant steroid-resistant nephrotic syndrome (SRNS). Eligible participants include pediatric patients aged 2 to 17 years who have either failed to respond to adequate CNI therapy or are resistant to at least two classes of immunosuppressants, including CNIs and biologics. A short course of low-dose Blinatumomab will be administered in an open-label, single-arm, self-controlled trial design. The study seeks to determine whether Blinatumomab can reduce proteinuria and induce clinical remission in this difficult-to-treat population, offering a potential new therapeutic option for children with limited response to conventional therapies.
NCT07071597
Given that the treatment strategy for adolescent PNS has a significant impact on growth and development, but there are few cases and a lack of clinical research, this study plans to collaborate with several domestic top-tier children's nephrology centers to conduct a retrospective real-world study of adolescent PNS. The aim is to understand the current diagnosis and treatment status of adolescent PNS and compare the advantages and disadvantages of various therapies, in order to provide a more scientific, rational, and effective treatment plan for adolescent PNS.
NCT07003438
The objective of this clinical trial was to understand whether FMT is effective in treating steroid-dependent/steroid-resistant nephrotic syndrome in children. It will also learn about the safety of FMT. The main question it was designed to answer was: Did FMT reduce participants '24-hour urine protein content? What medical problems did participants experience while using FMT? The researchers will compare FMT treatment with and without FMT on top of conventional treatment to see if FMT is effective in treating steroid-dependent/steroid-resistant nephrotic syndrome in children. Participants will receive 2 FMT treatments, 1 endoscopic injection under anesthesia, 1 oral fecal bacteria transplantation capsule intake, and follow-up visits (weeks 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, and 48) every 4 weeks from the beginning of medication to our renal specialist clinic for drug efficacy evaluation and safety testing. Blood and fecal samples were collected to determine the effects of fecal bacterial transplantation on intestinal flora, fecal metabolomics, and intestinal mucosal permeability.

This internal pilot study is a single-center, open-label, randomized controlled trial at The Hospital for Sick Children (Toronto, ON, Canada). The primary objective of this pilot study is to determine the feasibility, safety, and resources needed to conduct the future full-scale randomized controlled trial.
NCT06792448
Idiopathic Nephrotic Syndrome is a rare disease of the kidneys, which typically affects children. For most affected children there is the need of a prolonged treatment with drugs reducing the activity of the immune system, also resulting in many side effects. Those patients, who do not respond to treatment, are at risk of kidney damage and of dialysis or kidney transplantation. It is currently impossible to predict the response to treatment, leading to unnecessary therapies with side effects as well as unclear prognosis in the affected children. The response of the idiopathic nephrotic syndrome to medications acting on the immune system explains its important role in the occurrence of the disease. With this study we aim to obtain predictors of the response to treatment right at the beginning of the disease, to adapt the therapy avoiding needless side effects. This will be done evaluating the blood and urine of affected children using state of the art molecular characterisation. We will evaluate the genetic predisposition, the cell trait changes and the presence of molecules in blood and urine that may affect the interaction between the immune system and the kidneys. We expect that the findings will improve treatment of children with idiopathic nephrotic syndrome and reduce the number of children suffering from unnecessary drugs related side effects.

NCT06185257
Chronic kidney disease (CKD) arises from many heterogeneous disease pathways that alter the function and structure of the kidney irreversibly, over months or years. The diagnosis of CKD rests on establishing a chronic reduction in kidney function and structural kidney damage. The best available indicator of overall kidney function is glomerular filtration rate (GFR), which equals the total amount of fluid filtered through all of the functioning nephrons per unit of time The definition and classification of CKD have evolved over time, but current international guidelines define CKD as decreased kidney function shown by GFR of less than 60 mL/min per 1·73 m2, or markers of kidney damage, or both, of at least 3 months duration, regardless of underlying cause . When GFR is less than 15 mL/min per 1·73m2 , a person has reached end stage kidney disease (ESKD), at which point kidney function is no longer able to sustain life over the long term. Options for patients with ESKD are kidney replacement therapy (in the form of dialysis or kidney transplantation), or conservative care (also called palliation or non-dialytic care Encephalopathy detected in patients with chronic kidney disease results from their exposure to several factors, such as uremia, hypertension, and fluid, and electrolyte disturbances (Brouns R, DyDeyn pp,2004) Uremic encephalopathy features include alterations of mental status (alertness and awareness alterations, poor concentration, psychosis, and hallucinations, without treatment of which stupor, and coma may develop) and motor system abnormalities, such as clouding of the sensorium as an early feature and delirium, seizures, and coma as late features (Palmer sc ,etal,2010)EEG is useful in assessing patients in uremic encephalopathy and in monitoring their progress. Electroencephalographic (EEG) findings correlate with clinical symptoms and, therefore, may be of diagnostic value. In addition, it can be useful to exclude other causes of confusion such as infection or structural abnormalities (Dijck Annemie Van,etal,2012). The EEG in uremic encephalopathy is generally abnormal, showing generalized slowing that becomes more severe as the condition worsens. EEG in CKD usually shows irregular low voltage with slowing of the posterior dominant alpha rhythm and occasional theta bursts. Prolonged bursts of bilateral, synchronous slow and sharp waves or spike and waves are characteristic. These changes stabilize with dialysis. EEG abnormalities in uremic encephalopathy is reflected through appearance of theta waves, disappearance of normal basic rhythms and diminished reactivity of EEG to afferent stimulation and domination by generalized delta activity. All these changes are mostly appreciated in the frontal leads (Al Arieff,Philadelphia,Ssaunders,2004)(Cl fraser, Arieff,Philadelphia,2001) A lot of studies have been done about uremic encephalopathy in acute renal failure patients. Very few data are available regarding EEG changes in CKD. This study evaluates the EEG findings in different stages of CKD.
