Filter by:immunoglobulin A (IgA) nephropathy (Berger disease) is the most frequent primary glomerulonephritis worldwide. This disease accounts for about 5% of the causes of end stage renal disease in France, representing a major public health issue. Its pathophysiology seems to be triggered by mucosal immunity abnormalities leading to the systemic misaddressing of mucosal IgA, generation of circulating immunoglobulin A1 (IgA1) immune complexes finally deposited in renal glomeruli leading to renal tissue inflammation and scarring processes. Among this pathogeny, innate immunity is involved at several steps, including mucosal immunity. In this regard, hydroxychloroquine has been shown to generate a global anti-inflammatory effect, particularly through its action on Toll like receptors and dendritic cells. This drug is well tolerated, widely used for other auto-immune diseases (e.g. Systemic Lupus Erythematosus) and very low priced. One randomized controlled study conducted in China has recently shown a significant drop in proteinuria of IgA nephropathy patients treated with hydroxychloroquine (-48.4%) compared to the placebo group (+10.0%), after a quite short-term follow-up (6 months) and a moderate statistical power (30 patients in each group). Considering (i) the potential mechanism of therapeutic effect on this disease, (ii) the well documented safety profile of the drug for rheumatologic indications and posologies, and its low cost (iii) its efficacy in reducing proteinuria in IgA nephropathy patients in a preliminary Chinese randomized control study, the investigators aim in this study at establishing the beneficial impact of hydroxychloroquine on IgA nephropathy in a double blind randomized controlled trial on a Caucasian French population with harder outcomes and a longer follow-up compared to the Chinese preliminary study.
The goal of this clinical trial is to explore the effectiveness and safety of Telitacicept in adults with refractory IgA nephropathy. The main questions it aims to answer are: - To evaluate the clinical efficacy of Telitacicept in patients with refractory IgA nephropathy. - To evaluate the safety and adverse reaction of Telitacicept in patients with refractory IgA nephropathy. Participants will be subcutaneously injected with 240mg of Telitacicept once per week. Study subject: After 6 months of sequential treatment with renin-angiotensin system (RAS) blockers or glucocorticoids, patients with pathological biopsy of 0.7≥5 g/24 hours of proteinuria was confirmed as refractory IgA nephropathy.
This prospective, randomized, controlled, multi-center clinical trial will evaluate the effect and security of reh-acteoside therapy for patients of IgA nephropathy.
Recent studies have shown an increased gastrointestinal reactivity and increased intestinal permeability in IgA nephropathy (IgAN). Probiotic supplementation is known to impact the gastrointestinal immune system possibly by improvement of both the immunologic and the non-immunologic intestinal barrier. Probiotic supplementation should thus theoretically have an effect on IgAN. In this study the investigators will study the efficacy and safety of Lactobacillus reuteri.
The purpose of this study is to assess whether a tailored diet, eliminating antigens to which IgA nephropathy patients have demonstrated sensitivity, will have an effect on proteinuria, renal function and other immunological variables.
