Active clinical trials for "Immune System Diseases"

This study will assess the development of gastrointestinal health in terms of digestive tolerability and immune-inflammatory response at the intestinal level comparing a conventional gluten-free cereal with a new cereal with prebiotics, probiotics and a very moderate amount of gluten. These are products adapted to infant feeding since 4 Months.

PRIMAVERA is a Phase IIa clinical trial, with the objective to assess the immunologic response to HPV vaccine in a population of immunocompromised girls. The principal hypothesis is that the immunologic response to tetravalent vaccine in girls who received immunosuppressive treatment is comparable to the immunologic response in girls that are not immunosuppressed.

Phase II multicenter, Canadian only study - open to 25 subjects. Study open to subjects with steroid-refractory or dependent chronic graft vs host disease. Series of 6 aphereses and 28 re-infusions over 24 weeks. Primary endpoint is FFS at 24 weeks. Primary objective is to measure the efficacy of CARE (Continuous Alloreactive T-Cell depletion and Regulatory T-cell Expansion)

Inborn Errors of Immunity (IEI) include clinically heterogeneous rare genetic diseases depending on mutations in about 300 different genes. Clinically, this group of diseases is characterized by the presence of infectious, inflammatory, autoimmune, and lymphoproliferative symptoms. Understanding the pathogenesis of these diseases can guide the implementation of targeted therapies and improve prognosis. In recent years, IEI have been described that do not necessarily present with repeated infectious symptoms but rather with autoimmune, lymphoproliferative, and autoinflammatory manifestations, or with forms of immunodeficiency with a spectrum of susceptibility to one or few infectious agents. In this case, simple laboratory tests are not sufficient to characterize the disease since no particular immunophenotypic changes are evident. To correct classify the patients and to improve knowledge on the pathogenesis of the diseases, complex immunologic-functional studies are required. These studies should be started prior to genetic analysis, with the aim of targeting and narrowing it down. Although the ever-decreasing costs of Next Generation Sequencing (NGS) methods make it convenient to analyse many genes or even the entire exome simultaneously, the analysis of the data resulting from NGS can be complex and provide results of uncertain interpretation. In these cases, immunologic-functional studies can clarify the real causal role of the identified genetic variants. The identification of genotype-phenotype correlation is crucial to establish new therapeutic targets for diseases orphan of specific etiological treatments. In vitro and in vivo disease models are key tools to test drugs repositioning, as was the case for Lapaquistat in the treatment of periodic fevers caused by de-regulation of the cholesterol metabolic pathway.

This study evaluates the interaction between host immune cells and bacteria associated with periodontitis. It comprises biological material from donors with and without periodontal disease. Specifically, we collect a spit and blood sample to conduct in vitro stimulations and measurements of selected parameters related to periodontitis to clarify obscure areas in the immunologic pathogenesis of this disease.

To determine if artificial intelligence allow to detect lymphocyte subpopulations specific of diseases (such as primary Sjogren' syndrome and systemic lupus erythematosus) among patients with suspicion of autoimmune diseases.

Patients followed in Internal Medicine bring together favorable conditions for the use of alternative medicines. While some are recognized for their benefits, some can, on the contrary, harm the patient. It is therefore proposed to make a complete descriptive inventory of these practices, through an anonymized questionnaire. The main objective is the evaluation of the proportion of the use of alternative medicines in patients with in the department of Internal Medicine A

Bereavement refers to the expected reactions and sadness associated with the loss of a loved one. It has been reported that the loss of a spouse is rated as the major life stressor among survivors of varying ages and diverse cultural backgrounds. Statistics have shown that in the United States over 800,000 men and women lose a spouse each year. A wide range of symptoms has been associated with bereavement including; depressed mood, tearfulness, sleep disturbances, and irrational behavior. Previous studies have shown that up to 50% of bereaved individuals can develop major depression. Bereavement has also been associated with dysfunction of the immune system. As a result, bereaved adults are more vulnerable to infection. However, the exact relationship between bereavement and immunity is uncertain. Researchers firmly believe that a relationship does exist between stress, more specifically bereavement, immunity, and the increased chance of dying following the loss of a long-term spouse. The objective of this study is to find possible links between bereavement, depression, and the immune system. This study will follow a group of elderly bereaved spouses and a group of elderly people who have not lost a long-term spouse. The group of bereaved individuals will be followed for approximately 13 months after the loss of their spouse and the group of controls will be followed for 13 months after entering the study. Researchers will make note of any clinical, biological, and immunological changes in any participants of the study.

Systemic lupus erythematous (SLE), systemic sclerosis (Ssc) and inflammatory myopathy (IM) are rare diseases, whose prevalence is estimated at 43, 15 and 10 cases, respectively, for 100 000 inhabitants in France. These diseases belong to the group of auto-immune diseases and require specialized follow-up in an expert centre. The repercussions of SLE, Ssc and IM on the everyday life of patients are heavy, and notably linked to skin involvement, to diminished functional capacities and psychological problems. The vast majority of these diseases concern middle-aged, professionally-active individuals, for whom the socio-professional repercussions are major and too often neglected. The aim of this study is to analyse the consequences of auto-immune diseases on quality of life. Current quality of life questionnaires are not suitable, and do not reveal the reality of the situation and its different nuances. In this research, the quality of life of patients will be envisaged through their everyday lives. How do these patients construct the social reality of the disease? How do they perceive their health status and their social situation? How do they organize their everyday lives around the disease: work, leisure, relationships with their entourage... ?

The objective of this study is to determine the percentage of children with genetic markers putting them at increased risk of developing type 1 diabetes, and to offer the opportunity for these children to be enrolled into a phase II b primary prevention trial.
