Filter by:Objective: To search for potential biomarkers obtained by non-invasive methods (24-hour urine collection) that distinguish between patients diagnosed with systemic lupus erythematosus with or without renal involvement, patients with non-autoimmune renal disease and healthy donors. Lupus nephritis is one of the most common and severe complications of systemic lupus erythematosus, causing from asymptomatic mild proteinuria to rapidly progressive glomerulonephritis with kidney failure. To date, kidney biopsy (an invasive medical procedure with associated risks and complications) is essential for making a definitive diagnosis, assessing the severity of the damage and deciding on the best treatment. In relation to this, the identification of biomarkers using a non-invasive biological sample could help to classify population groups, and this would be a great step forward in the clinical setting. In this research project, we propose to conduct a case and control study. For this, we will first carefully classify the study groups, using clinical data on patients and by testing a pool of peptides described in the scientific literature in each of the sample groups, using solid phase extraction combined with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Subsequently, we will carry out multivariate principal component analysis on the data collected, and calculate corresponding receiver operating characteristic curves, to enable us to identify the masses corresponding to peptides with potential as biomarkers. We will then use classification algorithms to select sets of masses that would allow us to distinguish the population groups, and generate statistical classifiers for assessing the level of confidence in the model and its subsequent validation.
The purpose of this study is to evaluate the safety and efficacy of mesenchymal stem cells (MSCs) obtained from bone marrow for the treatment of adults with active proliferative lupus nephritis. The objective of this study is to evaluate the efficacy of mesenchymal stem cells (MSCs) in achieving a full response in the treatment of Lupus Nephritis (LN) during its induction period.
Introduction and background : Glomerulonephritis and auto-immune diseases are often associated. Lupus nephritis (LN) is one of the major clinical manifestations of systemic lupus erythematosus (SLE) which have a severe impact on prognosis. This complication is a real challenge for clinicians because of insidious-onset and no predictable relapses. Biomarker use is therefore essential, but conventional biomarkers such as proteinuria have poor sensivity and low specificity to predict LN occurrence, and new more reliable biomarkers (genetic, epigenetic or protein biomarkers) are difficult to use for daily medical practice. Anti-glomerular membrane basement disease (anti-GBM disease) is a rare (0.5 to 1/millions of inhabitants) and severe illness, characterised by rapidly progressive glomerulonephritis, pulmonary haemorrhage and the presence of anti-GBM antibodies, which are highly sensible (100%) and specific (92-100%) of this condition . Our experience and literature review In our department of internal medicine, we report one case of anti-GBM glomerulonephritis associated to an active SLE. After literature review, we note the following studies: - some similar association cases had been reported. - In 2006, a Chinese cohort study highlighted important rates of anti-GBM antibodies, in serum samples from patients with SLE (14 positives/157patients (8.9%) using ELISA method). Moreover, every SLE patient with positive circulating anti-GMB antibodies LN and a severer SLE (with significantly more anemias, pulmonary hemorrhage). According to histological data's, they also had more important kidney damages (10/14 had necrotizing crescentic glomerulonephritis lesions and 5/14 fulfil criteria's for anti-GBM disease diagnosis). - We also note that some authors published experimental studies showing that immunological and genetic links exist between LN and anti-GBM disease, which could explain this association. 3. Main Hypothesis: Based on these findings, we suspect that detection of significant levels of circulating anti-GBM antibodies may be more frequent in SLE followed patients than in general population, and that it could be an interesting biomarker of LN in patient with SLE. 4. Objectives First objective: based on 2 SLE patient groups (one having lupus nephritis and the other without it) we would like to compare the ratio of positive anti-GBM antibodies in each group, expecting a higher rate in SLE patients with LN. Second objective: will be to study the positive anti-GBM group patients in their clinical aspects, serological features and renal characteristics, in this SLE population. 5. Materials and methods We suggest a retrospective analytic transversal controlled study, based on serum samples from the Lupus Biobank of Upper Rhine (LBBR project), and based on serum samples from healthy voluntary blood donors (control group). We will then perform tests in each serum sample group in our immunology laboratory and compare the ratio of positive anti-GBM in each arm.
The purpose of this study is to explore the safety, tolerability and activity of Nivolumab, a PD-1 inhibitor, in cohorts of patients with autoimmune disease. Two cohorts of patients will be enrolled, based on autoimmune disease type. Patients will be screened within 28 days prior to the start of dosing. Eligible patients will be enrolled in either of the two cohorts. Patients will receive treatment every two weeks, in an outpatient setting. One cycle is a 28-day period, with Nivolumab given on days 1 and 15 of a 28-day cycle. Subjects will be permitted to continue treatment beyond initial RECIST 1.1.
This study is designed to evaluate the safety, tolerability, pharmacokinetics and therapeutic efficacy of treatment with either VAY736 or CFZ533 in patients with SLE to enable further development of these compounds as treatment in this disease population
A randomized, double-blind controlled, multicenter study in SLE patients given AKBM-3031or placebo for 24 weeks (randomized period) and followed by an open label extension (OLE) treatment with AKBM-3031 for the next 24 weeks. Patients will be maintained on stable doses of background medications, except for glucocorticoids. Decreases in doses of glucocorticoids will be encouraged during the first 20 weeks of both the randomized and open label extension portions of the trial. Stable doses of glucocorticoids and other background medications are required during weeks 20-22 and 44-48.If indicated by the PI, brief increases in corticosteroids are permitted during the first 20 weeks of both the blinded and open label extension portion of the trial. The increase in prednisone (or equivalent) dose is limited to 2X the back-ground level to a maximum of20 mg/day for a maximum of 1 week (7 days) or to a single administration of intravenous methylprednisolone or equivalent at a maximum dose of 500mg. Stable doses of glucocorticoids and other background medications are required during weeks 20-22 and 44-48
The purpose of this study is to evaluate the breadth and potency of HIV-1 neutralizing antibody (nAb) responses and examine the safety and tolerability of an HIV gp120 protein vaccine (AIDSVAX® B/E) in HIV-uninfected adults diagnosed with Systemic Lupus Erythematosus (SLE) who have stable disease.
The reason for this study is to see how effective and safe the study drug known as baricitinib is in participants with systemic lupus erythematosus (SLE).

Systemic lupus erythematosus is systemic autoimmune disease characterized by a wide range of clinical manifestations, from skin and mucosal lesions to severe injuries in the central nervous system, kidneys and other organs. The presence of high titres of autoantibodies against nuclear components, immune complexes deposition, complement deficiency and lymphocytes infiltration in affected tissues, which causes tissue and organ damage are the main characteristics of the disease. Nowadays, many studies elucidate the essential role of autophagy in the occurrence, development and severity of systemic lupus erythematosus.
