Filter by:This is an observational study to evaluate the diagnostic and prognostic value of presepsin in the critically-ill immunocompromise patients.
Background : The occurrence of Primary immune deficiencies (PID) is rare in adults. Antibody deficiencies were the first PID to be diagnosed in adulthood and are mainly represented by common variable immune deficiency. The main manifestation of these PID are encapsulated bacterial infection which used to be recurrent and/or invasive, lead to hospitalization and have high rates of morbidity and mortality. Diagnosis of PID in adulthood may be supported by six warning signs from the European Society of Immunodeficiencies (ESID). However, their guidelines do not comprehensively describe symptoms of PID, even for patients with infections. The guidelines recommend screening adults for PID after at least two severe bacterial infections. The aim of this study is to screen for PID adult admitted to our hospital for encapsulated infection without any predisposal factor. Material and methods : - Monocentric study. Inclusion between September 218 and September 2021 - Inclusion criteria : 1. Age 18 to 65 years old 2. Invasive encapsulated infection (Streptococcus pneumoniae, Streptococcus pyogènes, Haemophilus influenzae, Neisseiria meningitidis or Neisseria gonorrhoeae ) - Exclusion criteria : 1. Medical history of PID 2. Medical history of Secondary immune deficiency (SID) 3. Local-regional factor that could predispose them to infection 4. Hospital-acquired infection - PID screening included the following: complete blood count, blood smear, immunoglobulin (Ig) isotype (IgA,M, G) and IgG subclass levels, total hemolytic complement and complement fractions (C) 3 and 4, alternative complement pathway (AP50) in case of Neisseria meningitidis (NM) infection, quantitative immunophenotyping of T, B and natural killer cells, specific antibody response to diphtheria, tetanus and pneumococcal vaccine and HIV serology. The clinical and laboratory diagnostic criteria used to identify PID were based on guidelines from the ESID and the Pan-American Group for Immunodeficiency (PAGID) - A consultation in the infectious Diseases Department or Internal Medicine will be scheduled the hospitalization 3 months later to include patients and perform PID screening.
1. The purpose of this study is to learn more about the changes in genes, cells and proteins that cause immune deficiency diseases. 2. The early stages of the study will focus on two groups of patients: 1. members of families in which several persons have symptoms or medical histories that suggest immune deficiency. 2. Patients who have received treatments with medications or drugs that affect functions of the immune system (secondary immune deficiencies). It is hoped that studies will provide guidelines for extension of the research to other patient groups. Up to 200 patients and family members will be invited to participate.
Thiotepa is a chemotherapy drug used extensively in bone marrow transplantation. Thiotepa is a prodrug that undergoes metabolic conversion in the liver by CYP2B6 and CYP3A4 to its primary active metabolite, triethylene phosphoramide (TEPA). The goal of this study is to determine what causes some children to have different drug concentrations of thiotepa and TEPA in their bodies and if drug levels are related to whether or not a child experiences severe side-effects during their bone marrow transplant. The hypothesis is that certain clinical and genetic factors cause changes in thiotepa and TEPA drug levels in pediatric bone marrow transplant patients and that high levels may cause severe side-effects.
Human immunodeficiency virus (HIV) infection is characterized by persistent immune activation and a constant turnover of T cells. This leads to a precipitous fall in the number of T cells, as well as to an early immunosenescence. This results in increased susceptibility to opportunistic infections. In these patients, modulation of the immune response represents a promising mechanism to maintain immunological homeostasis and prevent the development of pathology. We hypothesize that the addition of pyridostigmine to the regular combined antiretroviral therapy will result in a decrease in T cell overactivation and a reduction in circulating inflammatory markers.
This open-label field trial evaluates the effects of treatment with a multi-pathway dietary supplement (Stem Cell 100+) that has been commercially available for several years. The objective of the intervention trial is to determine if normal subjects over 35 years of age experience any observable health benefits from the dietary supplement as to their blood pressure, pulse rate, blood cholesterol, lung capacity, stress levels, or self reported changes in markers of overall health and life expectancy.
To investigate the impact of consuming dairy yogurt on immun function including natural killer (NK) cell activity, circulating levels of cytokines, and immunoglobulin (Ig) in elderly.
To investigate the impact of supplementing fermented Maillard reacted whey protein (F-MRP) on natural killer (NK) cell activity, circulating cytokines and serum protein levels.
Needle-related procedures are the most important source of pain and anxiety in pediatric patients. Consequently, needle-phobia and anxiety are common in children with auto-immune disease and immune deficiency and may be barriers to adherence in treatment. The use of a non-pharmacological and easy-to-use approach, like the Buzzy® device, could be an alternative or adjuvant for the management of procedural pain and anxiety of these children during needle-related procedures. This study aims to determine the feasibility, acceptability and satisfaction of the Buzzy® device for procedural pain and anxiety relief of immunology-rheumatology patients undergoing needle-related procedures. The investigators will compare the Buzzy® device with an anaesthetic cream (Maxilene®) during needle-related procedures. The investigators also plan to assess feasibility outcomes and satisfaction of the nurses and the children with the use of the Buzzy® device. This pilot study should refine or modify the research methodology and improve the intervention being piloted before it's efficacy will be verified within a larger scale-study. The investigators strongly believe that the use of the Buzzy® device in immunology rheumatology department could optimise procedural pain and anxiety management. Since most of the treatments administered for auto-immune diseases and immune deficiency diseases are through subcutaneous or intramuscular injections, pain and anxiety management using non-pharmacological and/or pharmacological interventions should be prioritized. Given this knowledge, the investigators feel that this pilot study has the potential to contribute to pain and anxiety management of children undergoing needle-related procedures.
Metabolic syndrome (MetS) is a cluster of metabolic conditions associated with obesity that predispose individuals to coronary heart diseases and diabetes but obesity has been shown to increase the risks of other diseases like cancer and asthma. Studies have also shown that obesity increases the risk of severe influenza infection and associated death and reduces the efficacy of influenza vaccine in the obese population but yet, the molecular mechanisms have not been described. The investigators are thus hypothesizing that differences in the innate immune responses between individual with or without metabolic syndrome impact viral infection and vaccine outcome. The investigators will perform seasonal influenza vaccination in people with or without metabolic syndrome to determine if the late adaptive response assessed by antibodies titers is different between the two groups and correlates with the early immune response assessed by gene expression profile in whole blood cells. The project proposed by the investigators will contribute to a better understanding of the inflammatory phenotype associated with metabolic syndrome and establish for the first time if it affects the immune protection against infectious diseases and particularly against influenza virus infection. The results will be important to determine if the population affected by metabolic syndrome should receive anti-influenza treatment in priority in the context of a severe influenza epidemic.
