Breast Milk: Influence of the Micro-transcriptome Profile on Atopy in Children Over Time
This is an observational cohort study of 221 breast-feeding mother-infant dyads delivered at term. The goal of the study is to investigate whether levels of immune-related microRNAs (miRNAs) in maternal breast milk (MBM) influence child atopy risk in the first 12 months, defined as atopic dermatitis, wheezing, or food allergy. Infant exposure to individual miRNA components will be quantified at 0, 4, and 16-weeks after delivery using high throughput RNA sequencing of MBM samples and detailed dietary logs employing the Infant Feeding Practices (IFP) survey. The relationship of individual miRNA exposures (parts per million) and ...

Can Vitamin D Supplementation in the First Year of Life Prevent Food Allergy in Infants? The VITALITY Trial: Parts 1&2
We report that Australia has the highest prevalence of Immunoglobulin(Ig)E-mediated food allergy in the world, with 10% of infants having challenge-proven food allergy in Melbourne. There has been a 5-fold increase in hospital admissions for life-threatening anaphylaxis. These changes are most pronounced in children less than 5 years, suggesting a causal role for early life determinants. We have primary data to inform hypotheses for the rise in food allergy, which appears to result from potentially modifiable factors related to the modern lifestyle, particularly Vitamin D insufficiency (VDI). We propose an intervention study to ...

Clinical Utility of Handheld Hydrogen Breathalyzer in Identification of Food Sensitivities (AIRE Study)
Small intestinal bacterial overgrowth (SIBO) is defined as a condition in which an abnormally high amount of coliform bacteria is present in the small bowel and results in premature anaerobic fermentation of carbohydrates before reaching the colon. Commonly recognized causes include gastric achlorhydria, post-surgical bowel stasis, gastrocolic/coloenteric fistulas, and motility disorders leading to bowel stasis.. The current "gold standard" for the diagnosis of SIBO, is a breath test that measures the concentration of hydrogen in response to lactulose, a carbohydrate that is only metabolized by bacteria. However, its accuracy is only...

Combination Chemotherapy in Treating Patients With Non-Metastatic Extracranial Ewing Sarcoma
This trial examined the outcome benefit to patients of adding a new chemotherapy drug combination to the established treatment approach for patients with extracranial Ewing sarcoma, that had not spread from the primary site to other places in the body. The trial randomly assigned patients at the time of study entry to receive established standard treatment with the following 5-drugs: vincristine sulfate, doxorubicin hydrochloride, cyclophosphamide, ifosfamide and etoposide. The outcome for patients receiving the standard 5-drug combination was compared to the outcome for patients who received the same 5-drugs with an additional drug,...

Comparative Real World Effectiveness of SQ Sublingual Immunotherapy (SLIT)-Tablets vs. Controls in Allergic Rhinitis and Asthma
To assess the impact of SQ SLIT-tablets (SQ Grass SLIT-tablet and SQ HDM SLIT-tablet) in Danish and Swedish allergic rhinitis (AR) patients, with or without asthma, between 2007-2020.

Cow's Milk Elimination for Treatment of Eosinophilic Esophagitis
The investigators seek to assess the efficacy of removing cow's milk from an EoE patient's diet. This will be determined by esophageal inflammation and clinical and histological response to the milk elimination treatment.

Detection of Metabolite Biomarkers for the Early Diagnosis and Prognosis of Cow's Milk Allergy in Children
In this study, fecal and urine samples will be collected from children diagnosed with : - IgE mediated cow's milk allergy, - suspected of a cow's milk allergy, but with negative diagnosis - IgE mediated food allergy other than cow's milk - healthy brothers and sisters of the first three groups A subset of patients with IgE-mediated cow's milk allergy will be asked to provide a urine and fecal sample yearly for prognostic purposes. The samples will be analyzed using a technique called metabolomics to identify biomarker candidates with diagnostic and/or prognostic potential. Additionally,...

Dupilumab in Eosinophilic Gastritis
40 participants with Eosinophilic Gastritis 12-70 years of age will be randomly assigned with dupilumab or placebo subcutaneous injections every two weeks for a total of 12 weeks. Study subjects who complete the 12-week treatment phase, may continue into an open label extension study, where dupilumab will be administered every two weeks for a total of 24 weeks.

Efficacy of Dupilumab on Facilitated Food Introduction in Eosinophilic Esophagitis
Eosinophilic Esophagitis (EoE) is a food driven non-immunoglobulin E (IgE) mediated disease involving eosinophils and type 2 inflammation. Current therapies include diet and the off label use of medications including proton pump inhibitors, topical steroids or biologics. Food elimination creates a decrease quality of life in many children. The goal of the study is to examine a T2 inhibitor (dupilumab) can allow successful reintroduction of allergic EoE foods into the diet. This is a single site study, enrolling subjects 6 to 25 years of age.

Efficacy of Low-Dose Topical Steroids in Maintaining Remission of Eosinophilic Esophagitis in Children
This study evaluates the decrease in steroid dosing for patients who have achieved remission on a full dose of steroids. Once a patient is in remission they will be enrolled in this study if they choose to decrease the steroid dosing.
