Active clinical trials for "Nephritis"

The efficacy measure of hUC-MSC in the treatment of proliferative lupus nephritis on remission of lupus nephritis (combined partial and complete remission) in terms of stabilization and improvement in renal function.

The purpose of this protocol is to determine whether Tacrolimus and Prednisolone are effective and safe in the treatment of the cyclophosphamide-resistant, refractory diffuse proliferative lupus nephritis

The aim of this study is to identify families with hereditary chronic tubulointerstitial renal diseases , characterize the phenotype and screen for mutations in known genesis (UMOD, REN, TCF2, NPHP1). Genome wide analysis will be performed in families without mutations identified.

OBJECTIVE To test whether Rituximab (RTX) is efficacious to achieve complete renal response (CR) in Lupus Nephritis (LN) patients with persistent proteinuria (≥1g/d) despite at least 6 months of standard of care (SOC). STUDY DESIGN Investigator-initiated randomized international open multicentric 104-week study.

The investigators wish to evaluate the discontinuation of maintenance immunosuppressive treatment after 2 years in patients with stable remission after a proliferative lupus nephritis. The patients will be continuing their treatment with hydroxychloroquine, possibly associated with low dose corticosteroids.

There is substantial clinical and biological intra and inter-patient variability in SLE. Vascular, renal and neurologic deficiency can be organ-threatening or even life-threatening, leading to increased morbidity and mortality. Thus, biomarkers of disease activity and prognosis are required for regular follow-up of SLE patients. Implication of Toll-like Receptors (TLRs) in SLE has been extensively studied in mice models and humans. Self nuclear antigens bind to TLRs which are located on the surface of dendritic cells, B-cells, and endothelial cells, leading to production of pro-inflammatory cytokines and pathologic autoantibodies involved in organ dysfunction of SLE patients. Moreover, TLR expression in SLE is significantly higher and significantly correlated with disease activity. Annexin A2 (ANXA2) is a member of the annexins superfamily which exists as a monomer or heterotetramer and is implicated in several biological processes. Most notably, it binds to ẞ2GP1/anti-ẞ2GP1 antibodies and mediates endothelial cell activation via a TLR4 signaling pathway, highlighting its key role in Antiphospholipid Syndrome (APS) frequently associated with SLE. ANXA2 is also involved in the physiopathology of SLE. Anti-DNA autoantibodies can bind with ANXA2 expressed on mesangial cells in lupus nephritis. Besides, a french study carried out in Amiens' University Hospital showed that vascular lesions in lupus nephritis were associated with a significant increase in vascular expression of ANXA2.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by the production of multiple autoantibodies. The prevalence and significance of antibodies against Ficolin-2 have not been yet investigated. The aims of this study were to determine the prevalence of anti-ficolin-2 antibodies among SLE patients and to investigate their potential as diagnostic and/or prognostic biomarkers in SLE. This study is a secondary phase of a serum sample analysis done in early 2015 in order to determine the prevalence of anti-ficolin-2 antibodies among the same cohort as the previously declared study (ClinicalTrials.gov ID: NCT02625831; Unique Protocol ID: 1841851v0). In this retrospective study, clinical data were obtained from medical files and blood samples were selected from preexisting biological collection. SLE patients (n=165) were informed and did not objected, they were matched to healthy controls (n=48). Disease activity was determined according to the SLEDAI score. Anti-ficolin-2 antibodies levels were measured in sera by ELISA and correlated to previously obtained Anti-ficolin-3, Anti-ficolin-2, anti-dsDNA and anti-C1q antibodies levels. The titer of anti-ficolin-2 antibodies was correlated with the SLEDAI score (p<0.0001). The presence of anti-ficolin-2 antibodies was associated with anti-ficolin-3 antibodies, anti-C1q and anti-dsDNA antibodies. Interestingly, the combination of anti-ficolin-3, anti-ficolin-2 and anti-C1q antibodies demonstrated higher specificity than any other traditional biomarker. These results suggest that anti-ficolin-3 and anti-ficolin-2 antibodies could be useful for the diagnosis of active nephritis in SLE patients.

The aim of this study is to conduct a pharmacoeconomic analysis to compare the use of Mycophenolate Mofetil or i.v. Cyclophosphamide as induction therapy from a third party payer perspective in LN patients in the Egyptian context

Prospective, monocentric, single arm, observational PMCF - Study on the Performance and Safety of Double-Shank Titanium Ligation Clip in Urology (Prostatectomy and Nephrectomy)

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.
