Active clinical trials for "Immune System Diseases"

Anaphylaxis is a severe life-threatening reaction following exposure to an antigen. Its incidence is progressively increasing in the general population over years, especially among children. The diagnosis can be difficult, and recommendations for follow up and prescription for an emergency kit are rarely provided after emergency visit. The Investigators will evaluate the management of pediatric anaphylaxis and clinical signs of allergy in the pediatric emergency department of Montpellier University Hospital

The main purpose of this study is to examine differences in quality of life and psychological distress for both Multiple Myeloma patients receiving treatment and their caregivers and to assess patient and caregiver prognostic understanding (understanding of the likely course of a disease over time) of Multiple Myeloma to guide development of more personalized treatment plans. This study looks to further understand quality of life changes throughout multiple myeloma therapy for both patients and caregivers to help determine ways to improve patient and caregiver understanding of illness and in turn, tailor customized treatment that best aligns with patient preferences. The study will use a series of questionnaires to measure quality of life, mood, coping strategies, and prognostic understanding.

This prospective study aims to investigate the role of IR-Seq in the diagnosis and disease monitoring in patients with IgA nephropathy.

The main outcomes of this study are to establish a cohort of well-phenotyped asthma patients with a recent history of an exacerbation. We aim to describe exacerbation profiles (phenotypes) of the cohort in terms of inflammatory/biomarker profile and bacterial/viral infection status and to compare these with exacerbation events in the sister APEX cohort.

The meningococcal quadrivalent conjugate vaccine (MenACWY) and the licenced multicomponent MenB vaccine (Bexsero®) have already been included in the Italian childhood immunization programme and recommendations for high risk categories have been also implemented. As by NIP, vaccination against MenB with either 4CMenB or fHbp-MenB is offered for free for several conditions including subjects with severe primary or secondary immunodeficiency. In Liguria Region meningococcal vaccination is actively offered to several chronic conditions including asplenia, patients with lymphoproliferative disease (also HSCT), subject treated with anti-CD20 mAb and HIV-positive. In Liguria Region there is a large diverse population with risk condition that, as by national and regional recommendation, receive meningococcal vaccination. For some of them, i.e. asplenic and complement deficiencies groups, evidence have been generated through an ad hoc clinical trial, while for other important groups there is clear need of immunogenicity data. In the proposed study, the Investigators plan to administer two doses of MenB vaccine (Bexsero®), 1-2 months apart, to adult patients living in Genoa area and belonging to following categories: Bone marrow transplant (HSCT patient) HIV positive Alfa-CD20 subjects (i.e. Patients candidates for / in treatment with biologic drugs such as Rituximab). Immunogenicity data will be then obtained from sera collected at the day of the first Bexsero dose and one month after the immunization course by Serum Bactericidal Activity (SBA) assay.

The aim of this non randomised retrospective study is to investigate the imaging (MRI) of auto-immune encephalitis at presentation, especially in diffusion-weighted sequences. Indeed, few series describe the MRI aspect of auto-immune at their beginning. Recognize early MRI abnormalities seen in auto-immune encephalitis could help reduce the time to positive diagnosis and improve the therapeutic management.

CORIA is an observational cohort study of immunosuppressed populations who test positive for COVID-19. This includes people living with HIV, cancer, acquired immunodeficiency associated with other immunosuppressive therapy, primary immunodeficiency and recipients of a solid organ transplant. Participants will have routine clinical data collected with optional baseline collection and storage of a blood sample for storage . The study will be conducted in up to 30 sites within Australia.

Multiple sclerosis (MS), debilitating disease involving primarily the central nervous system, may cause cardiovascular dysfunction, due to autonomous nervous system dysfunction, physical invalidity, increased oxidative stress, and systemic inflammatory status, but the detailed mechanisms are not elucidated. The investigators aimed to assess left and right ventricular (LV and RV) function, left atrial (LA) function, arterial function, and atrial-ventricular-arterial coupling in patients with MS, compared to control subjects. LV systolic and diastolic function and RV function were assessed by 2D- and 3D- echocardiography, tissue Doppler, and speckle tracking echocardiography. LA function was assessed by LA volume index and LA strain. Arterial remodeling and stiffness were assessed by intima media-thickness, pulse wave velocity, and parameters of wave intensity and endothelial function
