Filter by:About 20% children with allergic purpura develop nephritis syndrome or nephrotic syndrome, 1% to 7% to kidney failure or end-stage renal disease. Children with serious damage to health, significantly reduced quality of life and caused heavy economic burden to the family . As the pathogenesis of HSPN is complex, it is difficult to formulate an exact individualized treatment plan.
The objectives of this study are to evaluate the safety and efficacy of ravulizumab administered by intravenous (IV) infusion compared to placebo and demonstrate proof-of-concept of the efficacy of terminal complement inhibition in participants with LN (LN Cohort) or IgAN (IgAN Cohort).
Lupus nephritis (LN) is one of the main manifestationsin SLE patients, having an important impact on morbidity and mortality. Renal biopsy is the "gold standard" for the diagnosis of LN, however, it is an invasive technique, not free of complications,which is not recommended to be performed serially as a follow-up tool for patients with LN. Searching for biomarkers in SLE has been the subject of interesting research, although results have not always been relevant. Multiple biomarkers have been studied in different locations (soluble markers in blood, urine and biological fluids),of different nature(autoantibodies, genetic markers of "kidney damage") looking atdiagnostic and/orprognostic features. In recent years, several biomarkers have been developed that seek to find an association with pathological patterns, with pathogenic mechanisms and with a non-invasive diagnosis of different glomerulopathies, allowing the identification of prognostic subgroups in each type of kidney disease, while predicting response to treatment and/or recurrence. To date, double-stranded anti-DNA antibodies (anti-dsDNA) and serum complement are the only non-invasive routine biomarkers for monitoring renal activity in patients with LN. However, these markers are only the reflection of the immune activity of the disease and they are not markers of renal damage or poor prognosis. For all the above, the purpose of this study is, in a case-control study, to evaluate simultaneously serum (ANA, anti-dsDNA, anti-C1q, anti-cardiolipin IgG and IgM, anti-ß2GPI IgG and IgM, anti-phosphatidylserine/prothrombin antibodies, and anti-DFS70 antibodies) and urinary biomarkers, and the presence of anti-DFS70 antibodies, in a multiethnic cohort of patients with SLE such as the cohort of GLADEL, and assess its possible correlation with various socio-demographic, clinical and serological manifestations of the disease. In subgroup of patients, transcriptome studies will be performed using RNA from blood and tissue to identify possible transcriptional signatures.
This observation study is planned to evaluate the safety and efficacy of the subjects who received CS20AT04 in the phase 1 clinical trial. If the subjects who participated in the phase 1 clinical trial voluntarily agree to participate in this observation study, visit 1 and visit 2 will be conducted every 3 months according to the clinical trial protocol until 6 months after administration of CS20AT04 in the phase 1 clinical trial. And Visit 3 after 6 months, Visit 4~Visit 7 will be conducted every 12 months. During each visit, subjects are assessed for the efficacy and occurrence of adverse events.
Lupus nephritis (LN) is one of the most severe complications of systemic lupus erythematosus (SLE). Among people living with SLE, 35-60% will develop LN during the course of the disease. This complication is one of the factors that contribute to deterioration of the renal function. Some centres perform kidney biopsies after completion of treatment for an episode of LN as a part of the treatment evaluation. The term "repeat biopsy" is often used to describe these biopsies. Several studies have reported that repeat kidney biopsies show activity at the level of tissue, even in patients with normal routine blood and urine markers. The investigators strongly believe that this information is important, and should be taken into consideration during decision of treatment. To provide evidence for this, the investigators have designed a collaborative project within the frame of the Lupus Nephritis Trials Network. With this research project, the investigators want to contribute to an increased proportion of patients with LN who achieve remission (inactivity) of LN, and a reduced proportion of patients who worsen in renal function in the long term. Patients with SLE who develop a first episode of LN will be asked to participate in this project, and will receive treatment according to current guidelines. Half of the patients will undergo a repeat biopsy 12 months later, and half of the patients will not. The selection of patients who will undergo or not undergo repeat biopsy will be random. Patients with high disease activity at the level of kidney tissue will receive more intense immunosuppressive treatment. Patients who have not undergone repeat biopsy will continue to be treated according to standard routine. The investigators will compare the results of treatment between the group of patients who underwent and the group of patients who did not undergo repeat biopsy, with regard to (i) complete disease inactivity at month 24 and (ii) renal function at month 60 from treatment initiation. The investigators expect that significantly greater proportions of patients in the repeat biopsy group will have inactive disease at month 24 and adequate levels of renal function at month 60. This will provide support for performing repeat biopsies as a part of the treatment evaluation, in order to optimise the therapeutic management and improve the long-term prognosis of patients with LN.

A Prospective randomized trial with a primary objective to investigate the effect ofprdenisolone treatment in acute interstitial nephritis
B-cell activating factor (BAFF), serves as a vital survival and differentiation factor for normal B-cell development. BAFF levels have been associated with the clinical activity of SLE in humans. BAFF plays a pathogenic role in SLE in part through T cell-dependent B cell autoantibody production. BAFF, has a role in the maintenance of memory B cells and promotes plasma cell survival. Treatment strategies involving BAFF blockade haven been studied in patients with SLE inducing overall improvement in disease activity, mainly in musculoskeletal and mucocutaneous domains leading to the approval of Belimumab for the treatment of patients with SLE without severe renal or neurological involvement. Antibodies against CD20 molecule, (Rituximab), cyclophosphamide (CYC), and mycophenolate (MMF) have all been used for the treatment of different manifestations of SLE and both moderate and severe activity. Baseline C4 level, early normalization of complement, and reduction in proteinuria have been shown to predict renal response to therapy with MMF or CYC in lupus nephritis. With Rituximab (RTX), B cell depletion has been associated with response to treatment and relapse prediction. The elevation of serum BAFF levels after B cell depletion with RTX in SLE are associated with anti-double-stranded DNA antibody levels and disease flare. The rise of BAFF is probably due to the decrease in its receptors leading to a release of BAFF and a delayed regulation of BAFF mRNA transcription, both of which could favor the re-emergence of autoreactive B cells. It has been suggested that the rise in BAFF levels after anti-CD20 therapy might be related to flares of the disease. Additionally, the combination of anti-CD20 with anti-BAFF or antibodies against CD4, reduces the number of splenic plasma cells in mouse models and has been proven to have a lasting benefit both in lupus-prone mice and in mice with established disease. Currently, there is a lack of information regarding MMF or CYC and BAFF levels. We consider that it is fundamental to know the behavior of BAFF in patients with SLE after treatment with MMF or CYC bearing in mind the proposal of multiple experts of the possible use of sequential therapy of BAFF inhibition after B-cell depletion. Knowledge of the behavior of BAFF will allow me to better understand its implications in SLE and its therapy and postulate the use of sequence therapy with Belimumab after CYC o MF induction with the proposal to reduce the flares
