Filter by:Investigators aim to develop an effective and safe treatment of autoimmune diseases through adoptive T regulatory cells transfer. Our objectives are to evaluate the safety and efficacy of autologous adoptive Treg (CD4CD25FoxP3 CD127 low regulatory) cell transfer to patients with refractory autoimmune diseases: Refractory lupus Nephritis, and adults' type1 diabetes mellitus. Patients and Methods: This is Non randomized open label phase 1 pilot study including ten patients with refractory lupus nephritis and ten patients with Type 1 diabetic patients. All patients will be subjected to Full history taking, clinical examination and pretreatment investigations according to the type of autoimmune disease then regulatory T cells (Tregs) identification and count, Treg isolation and expansion and finally administration of T reg cells and follow-up of adverse events and outcomes.
Interleukin 2 (IL-2) is a critical cytokine for the survival and function of regulatory T cells (LTreg). This cytokine has a dual role in the immune system. IL-2 stimulates immune responses by acting on the intermediate affinity IL-2R receptor, IL-2Rβγ, expressed by conventional T cells (LTconv) during activation, but also contributes to the inhibition of immune responses via LTreg that express the high affinity receptor IL-2Rαβγ. This difference in IL-2 receptor affinity for IL-2 has led to the development of low-dose IL-2 therapy to stimulate LTreg and improve control of excessive inflammation in autoimmune (AID), inflammatory or alloimmune diseases Low-dose IL-2 therapy is being studied in several of these diseases such as systemic lupus erythematosus, type 1 diabetes, alopecia, HCV (hepatitis C virus)-induced vasculitis, atopic dermatitis and chronic allo-transplantation-related graft-versus-host disease (GVHD). Some of these studies have shown an increase in LTreg numbers and an improvement in certain clinical signs. To improve LTreg targeting in autoimmune diseases, inflammatory diseases or GVHD, mutated IL-2s (muteins) have been developed with selective LTreg agonist properties. These IL-2 muteins are linked to an Fc fragment to increase their half-life. Two IL-2 variants (IL-2Vs)-Fc preferentially stimulate STAT5 phosphorylation in LTregs compared to conventional FoxP3- (LTconv) CD4+ or CD8+ T cells
Factors associated with severe forms of COVID-19 infection in patients with inflammatory rheumatic diseases (IRD) or Autoimmune Diseases (AID) are unknown. This unprecedented situation leads to empirical and potentially erroneous advice and recommendations for care. Identifying factors associated with severity, in the context of this pandemic, which is expected to last many months, and possibly years, is crucial for future patients. The objective of this work is to identify the factors associated with the occurrence of severe forms of COVID-19 infection in patients with IRD or AID, by combining analysis of 2 large databases.
The main objective of this study is to generate diagnosis and therapeutic-decision tools through the identification of molecular causes of PIDs with autoimmunity/inflammation and the variability in disease outcome at the transcriptional level using a combination of omics signatures (transcriptomics, epigenomics, proteomics, metagenomics, metabolomics and lipidomics).
Multiple sclerosis (MS) is the most common demyelinating disease of the central nervous system and the most common cause of non traumatic disability in young and middle-aged people. Neuromyelitis optica spectrum disease (nmosd) is an independent disease different from Ms. the pathogenesis and the mode of brain and spinal cord injury are different from MS, and the prognosis and optimal treatment are different. It is difficult to distinguish the two diseases in the early stage. Early diagnosis and treatment of the two diseases can greatly improve the quality of life of patients. Therefore, it is an urgent problem to clarify the difference between MS and nmosd injury patterns and to find sensitive imaging markers for early clinical intervention. With the continuous progress of computer aided diagnosis (CAD), it is more and more widely used in medicine, which is expected to help solve the above problems. The purpose of this study is to create a neuroimmune disease evaluation database based on image data. By combining brain and spinal cord imaging, and based on Zhang quantum space learning computer-aided technology, we can achieve accurate segmentation of MS and nmosd brain and spinal cord lesions, analyze the evolution characteristics of the disease at different time points, and screen the imaging indexes related to clinical scores combined with clinical and laboratory indexes Objective: to determine the different prognosis and its influencing factors at the clinical, imaging and molecular levels, and establish the model for predicting disease progression and prognosis, so as to provide the basis for early identification and assistance in guiding treatment and judging prognosis. Clinical information was collected: age, gender, course of disease, MMSE, EDSS disability score, nine hole test, 25 foot walking test. Assess the patient's information processing ability. Blood samples were collected. Imaging examination was performed. The patients were followed up regularly.
Exploration of pathophysiological mechanisms in chronic inflammatory rheumatism and rare systemic autoimmune diseases with the objective of identifying therapeutic targets.
Approximately 80 patients affected by moderate to severe psoriasis will be screened for the presence of LL37( and ADAMTSL5 autoreactive T-cells in their blood at Day 0. Patients whose lymphocytes reacted with proliferation to LL37 or ADAMTSL5 will receive SKYRIZI (Risakizumab) at Day 1, week 4, 16, 28, 40. LL37 and ADAMTSL5-specific T-cell responses will be evaluated at Day 0, week 16, week 28 and week 52. Each patient will be followed for 52 weeks.
Description of the short and long-term impact of hypnosis sessions for patient having benefited from at least one hypnosis session in internal medicine at the french hospital "Groupe Hospitalier Mutualiste de Grenoble", with the help of a qualitative survey made by phone.
In the plasma of any pregnant patient circulates DNA (also called circulating free DNA). The vast majority of this circulating free DNA is of maternal origin and about 10% is of fetal origin (fetal circulating free DNA). This percentage of fetal circulating free DNA (corresponding to the fetal fraction) increases with gestation. The pathophysiological hypothesis of this research is that there is a change in the fetal fraction (FF) of fetal circulating free DNA in patients with autoimmune disease (AID). The underlying mechanism would be a massive release of maternal cfDNA responsible for a dilution of fetal cfDNA. This dilution of fetal cfDNA would result in a decrease in the estimate of the foetal fraction of circulating free DNA. However, when the foetal fraction of circulating free DNA is insufficient (4% most often), screening for Trisomy 21 (T21) by fetal circulating free DNA becomes uninterpretable (NC for "non-contributory" result), and cannot be used to assess the risk of T21. In this case, the dose of fetal circulating free DNA can be performed again after 15 days, as the amount of fetal circulating free DNA increases with gestation. In a small number of cases the result will remain NC. As tests using DNA are becoming more widespread, it is important to prospectively evaluate the results of these tests in the population of patients with AID, which represents about 3 to 5% of pregnant women.
A group of poorly studied immune-mediated neurological syndromes are associated with antibodies against glutamic-acid decarboxylase (GAD-Ab). GAD is the rate-limiting enzyme for the synthesis of gamma aminobutyric acid (GABA) from glutamate and is expressed by inhibitory neurons of the central nervous system. Neurological syndromes with anti-GAD antibodies (GAD-Ab) are often non-paraneoplastic. They mainly include limbic encephalitis (LE), cerebellar ataxia (CA) and stiff-person syndrome (SPS). Although the pathogenic role of GAD-Ab is controversial, most patients have high serum levels and GAD-Ab are also detected in the cerebrospinal fluid (CSF) along with other inflammatory abnormalities such as oligoclonal bands. GAD-Ab may also be present in the serum of T1DM patients, as pancreatic beta cells also express GAD, but usually at much lower titers than those of neurological patients. Organ-specific autoimmune diseases, such as T1DM and autoimmune thyroid disease, are common among patients with GAD-Ab and neurological syndromes and in their relatives, suggesting a shared genetic predisposition to autoimmune disorders. This is also supported by family reports of neurological syndromes with GAD-Ab and some HLA associations described in SPS. The aim of this study is to describe the different autoimmune organ-specific diseases present in patients with GAD-Ab and their relatives, along with to identify families with higher aggregation of autoimmune diseases and establish potential ways of inheritability.
