Fatty liver disease is a global health concern with a prevalence of about 25% amongst United States. Its increased prevalence is attributed to increase in patients with obesity and metabolic syndrome (1). Diabetes mellitus (DM),obesity, hyperinsulinemia are predisposing factors for fatty liver disease(2). Glomerulonephritis (GN), a complex syndrome encompassing a variety of individual disorders, is associated with significant morbidity and mortality(3). Given its association with hyperlipidaemia, metabolic syndrome and long-term use of steroid there is concern that patients with GN may be at increased risk of fatty liver disease Patients with NS are frequently found to have fatty liver disease even when adjusting for common risk factors(1). It is known that obesity is an independent risk factor for CKD and it is associated with the development of proteinuria and pathologic findings of podocyte hypertrophy and focal segmental glomerular sclerosis even in the absence of diabetes and hypertension . In addition, studies have shown that obesity as well as metabolic syndrome is a strong predictor of the development of fatty liver disease (4) . Hence, clinicians should maintain a high index of suspicion regarding presence of NAFLD in patients with NS
A classification has introduced C3 glomerulopathy (C3 glomerulopathy consensus report) that should be used to designate a disease process due to abnormal control of complement activation, deposition, or degradation and characterized by predominant glomerular C3 fragment deposits with EM dense deposits. Also, the consensus suggested that the term glomerulonephritis with dominant C3 should be used in practice as a morphological term for those cases with dominant C3 (C3c satining) which is defined as C3 intensity ≥ 2 orders of magnitude more than any other immune reactant on a scale of 0 to 3. C3 glomerulonephritis with 3 dominant C3 deposits include C3 glomerulopathy, post-infectious glomerulonephritis (PIGN) and others such as para-protein associated glomerulonephritis. In C3 glomerulopathy; the alternative pathway plays a major role in pathogenesis of this group of diseases. It occurs because of dysregulation of alternative complement pathway. Dysregulation can be due to mutations of complement proteins or to autoantibodies that promote complement activation. Classical/lectin complement pathway has shown potential in evaluation of C3 glomerulopathy. It's suggested that presence of glomerular C4d which is a product of early classical/lectin pathway, should not exclude a C3 glomerulopathy. Another disease group with prominent C3 deposits is postinfectious glomerulonephritis (PIGN) and although PIGN has traditionally been thought of as a disease triggered by glomerular immune complex deposition but C3 deposition in absence of immune complex deposits can be seen in patients with PIGN but with the emergence of C3 glomerulonephritis (C3GN), the distinction is difficult as the clinical and pathological presentation may be similar. However, their treatment and clinical course vary significantly. In addition there is overlap between PIGN and C3 glomerulopathy as they may both show prominent sub-epithelial humps on electron microscopy. This overlap means that it may be very difficult to decide on morphology alone whether a biopsy is a typical PIGN that will resolve, or whether it represents a C3 glomerulopathy due to an underlying complement abnormality that will lead to persistent glomerulonephritis.
The goal of this National Registry is to is to collect information from patients with rare kidney diseases, so that it that can be used for research. The purpose of this research is to: - Develop Clinical Guidelines for specific rare kidney diseases. These are written recommendations on how to diagnose and treat a medical condition. - Audit treatments and outcomes. An audit makes checks to see if what should be done is being done and asks if it could be done better. - Further the development of future treatments. Participants will be invited to participate on clinical trials and other studies. The registry has the capacity to feedback relevant information to patients and in conjunction with Patient Knows Best (Home - Patients Know Best), allows patients to provide information themselves, including their own reported quality of life and outcome measures.
The goal of this clinical trial is to learn if a new drug that might help protect and preserve kidney function in antineutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV). AAV is a type of autoimmune disease where the body's own immune system attacks itself, and in the case of AAV the body attacks its own small blood vessels. There are many small blood vessels in the kidneys meaning the kidneys are commonly affected in AAV. The main questions it aims to answer are: - Is the new drug well tolerated and safe? - Can the new drug protect and preserve kidney functions when is added to standard therapy? Researchers will compare the following groups to see how the new drug is tolerated and what effect to preserve kidney tissue has: - Group A: Standard treatment + ALE.F02 lower dose infusions - Group B: Standard treatment + ALE.F02 higher dose infusions - Group C: Standard treatment + placebo infusions (inactive substance) The Treatment period will consist of 24 weeks beginning on Day 1, during which time participants will receive 13 infusions of the study medicine, along with standard therapy for kidney inflammation due to AAV. During the treatment period, participants will have the following assessments: - A brief physical examination focusing on their skin any pre-existing medical conditions that you have. - Collection of blood and urine samples for routine safety tests and to assess renal function. - Collection of blood samples: - To measure the amount of study medicine in their blood. This is called pharmacokinetics (PK) and it is tested to see how study medicine enters, moves through, and exits the body. - To test for antidrug antibodies (ADA). To check if their body create antibodies against the study medicine, as this could reduce its effect. - To measure biomarkers. Biomarkers are specific compounds in the body (can be protein, hormones, or genetic molecules) that indicate normal or abnormal processes taking place in your body and may be a sign of an underlying condition or disease (for example glucose levels are used as biomarker in managing diabetes). They are used to see how well the body responds to a treatment for a disease or condition. - Collection of urine to measure urine markers of vasculitis/inflammation called biomarkers. - Urine pregnancy test. A urine pregnancy test is a quick medical test that can tell if a woman is pregnant or not by checking for a hormone which is produced during pregnancy, usually in the urine. - Chest High Resolution Computed Tomography (HRCT) scan to check whether they have vasculitis affecting their lungs. A CT scan uses special x-ray equipment to take detailed pictures of body tissues and organs to diagnose and monitor conditions in various parts of the body. For the CT scan, they will need to lie still on a table. At Week 24 a second lung CT scan will be performed for participants whose initial scan showed lung vasculitis to see whether your lung vasculitis is getting better or ongoing/worse.
This project aims to identify, through RNA-Seq technology, the genetic alterations underlying undiagnosed rare diseases in pediatric and adult patients with early onset and with negative WES. - Objective 1: Set up and validate techniques. Set-up and validation of the transcriptome analysis protocol in healthy subjects and in patients with known splicing alterations and/or altered RNA expression. - Objective 2: Diagnostic phase. Study of splicing alterations and RNA levels in cultured fibroblasts obtained from skin biopsies of patients with rare genetic diseases and negative exome. Exploratory goals - Compare the RNA expression profile obtained from skin biopsy-derived fibroblasts with the RNA expression profile from blood. The most relevant results will be validated in qRT-PCR. - To analyze the transcriptional and protein profile heterogeneity in skin-derived fibroblasts in enrolled subjects. To explore the effects of genetic (from WES) and transcriptional (from RNA-seq) alterations in participants' plasma and serum. Healthy controls Five healthy subjects will be recruited from the staff of the Mario Negri Institute for Pharmacological Research. The coded samples will be used to set up the method of isolation and culture of skin fibroblasts and RNA-Seq. Validation group For the set-up and validation of the skin fibroblast isolation and RNA-Seq procedure, ten adult patients with known diagnosis and with alterations in RNA levels and/or splicing will be recruited as positive controls. Patients who meet the requirements described above will be contacted by the doctors of the Daccò Center for an interview explaining the project. Those who agree to participate in the study will be asked to sign the informed consent before proceeding with the experimental part. "Discovery/Exploration" group The exploration cohort will be composed of 30 symptomatic undiagnosed patients with suspected genetic disease (children and adults with infantile onset) belonging to the Clinical Center of the Mario Negri Institute for Pharmacological Research and for whom WES investigations did not reveal causative genetic alterations.
This protocol is part of a larger project, COMPRare (COMPlement-mediated Rare kidney diseases), which has been financed on behalf of the EJP RD (European Joint Programme on Rare Diseases) program of EU and is leaded by a scientific consortium from 7 European countries. The partners (P) of the consortium are: P1. Radboudumc Amalia Children's Hospital (The Netherlands) P2. Semmelweis University (Hungary) P3. Cordeliers Research Center (France) P4. Max Delbruck Center for Molecular Medicine (Germany) P5. Istituto di Ricerche Farmacologiche Mario Negri (Italy) P6. Lund University (Sweden) P7. Lille University (France) The general aim of the project is to define new diagnostic tools for complement activation in order to improve patients stratification and follow-up, thereby affecting time and choice of treatment in patients with aHUS and C3G. Particularly, the specific objectives of the COMPRare are: - To develop new standardized analytic assays thereby identifying specific complement prognostic biomarkers for early diagnosis, classification, improved monitoring and treatment of patients with aHUS and C3G; - To in-depth characterize patients' complement abnormalities in blood, in patient-derived cells and in kidney biopsies; - To identify strategies to classify VUS/LPV - To find new pathophysiological pathways involved in aHUS and C3G for further improving disease diagnosis, monitoring and treatment. The results of these studies will form the basis of personalized treatment with existing and upcoming complement inhibitory drugs for these rare complement-mediated kidney diseases.
