Infant Formula Feeding and Necrotizing Enterocolitis in Newborns
Necrotizing enterocolitis (NEC) is the most common life-threatening gastrointestinal emergency of prematurity, associated with a significant morbidity and mortality. Early diagnosis and early treatment interventions may reduce the risk of mortality and morbidity. The Primary goal of this observational study is to gather survey data to establish a national database of NEC in newborns in order to better understand the risk factors underlying NEC. Survey data will be used along with a medical history to identify the mechanism(s) underlying the increased prevalence of NEC in non-breast fed, formula fed premature infants.
Intervention in Chronic Pediatric Patients and Their Families.
This project consists of a psychological intervention in patients and their families with different chronic diseases in order to carry out a comparative study between medical pathologies to know which are the protective or risk variables for the adaptation to the disease.
JAK Inhibition in Food Allergy
This study will assess the role for an oral targeted medication, abrocitinib, as a new treatment option for food allergy patients that would avoid injections. Abrocitinib, which has successfully completed phase three trials for atopic dermatitis, could serve as a single therapy for two conditions in many patients with multiple atopic conditions.
Long-term Extension Study of Ligelizumab in Food Allergy
This is an extension study to evaluate the long-term safety and efficacy of ligelizumab in particiants who have completed a ligelizumab Phase III study in food allergy.
Low Dose Multi-Nut Oral Immunotherapy in Pre-schoolers With a Multi-Nut Allergy
The LMNOP trial will be a 2-armed, open-label, randomised controlled trial (RCT), 2:1. Over a period of 18 months, children in the Multi-Nut Oral Immunotherapy Treatment (OIT) Group (experimental arm) will undergo low dose OIT to two nuts they are allergic to. At this time, children in the Standard Care Group (control arm) will be instructed to strictly avoid consuming two nuts they are allergic to. Avoiding consuming nut allergens is the standard care advice for children with peanut/tree nut allergies in Australia. The trial will assess the difference in the proportion of participants undergoing Multi-Nut OIT who can achieve ...
Microbiome and Immune Profiling in Infant With Cow's Milk Allergy
Non-IgE-mediated cow's milk allergy (CMPA) is associated to gastrointestinal symptoms, and its cause remains poorly understood, limiting the identification of specific markers to help with the diagnosis. Using a non-invasive method, the aim of this study is to identify new protein markers as well as to profile the bacteria (germs) released in stools of infants during the inflammatory process of this condition (acute and recovery phase). The study group will include infants who are born at term by an uncomplicated birth and diagnosed with non-IgE-mediated CMPA in the first 4 months of life, while the control groups will...
Molecular Basis of Food Allergy
The Study examines the molecular basis of food allergy. It explores the interaction between T cells, InKT cells and cytokines in the development of food allergy. The study also explores these factors in development of tolerance "outgrowing" food allergy. It will also explore the genetic factors that lead to the development of food allergy. The study examines all type of food allergy including IgE mediated reactions, Eosinophilic Esophagitis and Food Protein Induced Enterocolitis
Mucosal IgE to Improve Diagnosis of Food Allergy and Food Hypersensitivity
Aim of the study is to improve the diagnosis of food allergy and hypersensitivity. Intestinal homogenates will be used to determine total IgE, specific IgE, tryptase, histamine and inflammation parameters (IFNgamma, TNFalpha). These data will be correlated with serum values and disease status. In addition, organoids from duodenal tissue will be isolated and cultured in vitro and stimulated with the major food allergens. The gene and protein expression will be checked to identify relevant biomarkers.
National, Multicenter, Retrospective, Prospective Study to Evaluate Pediatric Gastrointestinal Eosinophilic Disorders
Eosinophilic gastrointestinal disorders (EGIDs) are a heterogeneous group of emerging chronic inflammatory diseases that may affect different gastrointestinal (GI) tracts. Based on the anatomical site involved, EGIDs are distinguished into eosinophilic esophagitis (EoE) and non-esophageal forms, which are subdivided into eosinophilic gastritis (EoG), gastroenteritis (EoGE), and colitis (EoC). EoE is considered the prototype of EGIDs. Since the first description of a case series of patients with EoE, fundamental scientific advances have been achieved, culminating in the redaction of international diagnostic and therapeutic guidelines....
Natural History and Genetics of Food Allergy and Related Conditions
Background: - About 15 million Americans have a food allergy. Because there are no cures or effective prevention or treatment for food allergies, researchers want to learn more about them. Objective: - To learn more about the causes and effects of food allergy and related conditions. Eligibility: - People ages 2 99 who have food allergy and/or a related genetic or other condition - Their relatives - Healthy relatives and volunteers Design: - Participants will have at least 3 visits over 1 2 years, and then once a year for up to 12 years. Each may last a day or longer. ...
