Active clinical trials for "Immune System Diseases"

Type 1 diabetes has been poorly characterised, with very sparse information available in the literature about the characteristics of the disease in Africa. Atypical young onset diabetes is often reported by clinicians in sub-Saharan Africa, including patients who have the phenotype of type 1 diabetes but do not appear to have an absolute insulin requirement. The onset of type 1 diabetes in many sub-Saharan African populations seem to occur at later ages (20s to 40s) than what is generally seen in Caucasian populations. The investigators seek to characterise young-onset insulin treated diabetes (clinically diagnosed type 1 diabetes) in sub-Saharan Africa;

This study aimed to survey the growth of children who were on elimination diet due to cow milk allergy in Turkey. 0-5 year aged children diagnosed with cow's milk allergy (CMA) and healthy age-sex-matched children as the control group was planned for inclusion. Participants will be included in the study by consecutive sampling. The anthropometry measurements (height-for-age [HFA], weight-for-age [WFA], and weight-for-height [WtHt]) will be evaluated according to the Z-score using the WHO ANTHRO [Z-score = Patient's value - Average value / Standard Deviation (SD)]. The Z-score (SDS) in the average child by age was "0".

Follow-up registry of patients living with HIV who also have various inflammatory and autoimmune pathologies that may require immunosuppressive treatment.

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.

Include qualified 50 ANCA-associated vasculitis(AAV) patients; and the first 27 patients will be divided into 3 groups with different diffused tension image (DTI) parameters and to choose the best strategy； On baseline, 6 months after treatment and 24 months after treatment, the AAV patients will accomplish the Birming-ham vasculitis activity score(BVAS) besides DTI； The new serum biomarkers of AAV associated peripheral neuropathy will be measured by ELISA； (4) Another cohort with 50 patients with AAV associated peripheral neuropathy who were evaluated by traditional methods (electromyogram) and compared to the patients cohort that evaluated using DTI by cost-benefit analysis

Migrant populations represent an increasing proportion of newly referred people living with HIV in Canada, particularly in Quebec. Timely HIV care of newly referred patients has important individual-level health benefits that can result in decreased transmission and benefit the society as a whole. Yet, the timing of events in the HIV care cascade (from linkage to care to sustained viral suppression) together with the specific experience of care of these vulnerable populations (asylum-seekers, international students, patients with no status) who often face specific psycho-social and/or financial issues, has rarely been studied. In particular, little is known about their experience of HIV care whether they are referred to a multidisciplinary clinic or a physician-only clinic. In a context where B/F/TAF will be provided free-of-charge to all enrolled participants including migrant populations, we aim to investigate what model of care can best address current deficiencies in the standard HIV care cascade for newly-referred patients, which often involves delays in linkage to care and starting ART.

Multiple myeloma (MM) is a malignancy of plasma cells engaging in monoclonal immunoglobulin production. A strong presumption was established between exposure to pesticides and the risk of MM. The French West Indies departments of Guadeloupe and Martinique are characterized by a wide use of pesticides related to bananas plantation, particularly chlordecone which has been classified by IARC as possibly carcinogenic and has recognized hormonal properties (endocrine disruptor). The objective of this study is to measure the association between exposure to pesticide and other environmental factors in the occurrence of MM in Guadeloupe and Martinique and to estimate the proportion of cases of MM attributable to pesticide exposure. Genetic susceptibility markers and their links to environmental factors will be subsequently studies from blood samples collection.

Investigators have aimed to estimate prevalence of neuropathic hand pain in RA patients and it's relation with sleep quality and sensory thresholds. For this purpose a case-control study design was planned. Age- and sex-matched control subjects will be chosen among individuals submitted to out-patient clinic with the complaint of nociceptive/mechanical pain other than in hand, lasting more than three months

The purpose of this study is to collect French medical data for patients with Multiple Sclerosis (MS) or NeuroMyelitis Optica (NMO) spectrum disorder who are diagnosed or strongly suspected of being infected with Covid19. The objective of this study is to provide scientific information regarding the possible risk factors in these patients, as a large part of them receive immunomodulatory or immunosuppressive treatments. The main objective of this study is thus to determine the epidemiological (eg, age, form of disease, disability) and pharmacological (related to immunomodulatory or immunosuppressive treatments) factors favoring the occurrence of a severe form of Covid-19 in MS and NMO patients.

This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records regarding Multiple Sclerosis.
