Hydrolysed Rice Formula Study
This non-inferiority study aims to determine whether a hydrolysed rice protein formula is as effective as a cow's milk protein based extensively hydrolysed formula using a double-blind, randomised-controlled design over a 28-day intervention period followed by a 2-month follow-up period in infants 0-13 months of age presenting with symptoms/clinical history suggestive of cow's milk allergy. The primary outcome is growth, and secondary outcomes are gastrointestinal tolerance, and differences in intake, allergic symptoms, parental QOL, acceptability, dietary intake, and safety.

Hypoallergenicity of a New Formula in Subjects With Cow's Milk Allergy
Cow's milk protein allergy (CMA) is an immune-mediated reaction which can either be antibody-driven (IgE-mediated) or cell-mediated (non-IgE-mediated) or mixed, and elicits reactions which are reproducible upon re-exposure to cow's milk proteins. Estimates of CMA prevalence depend on the diagnosis procedure used; recently, a meta-analysis stated an overall pooled estimate for 0-1 year old infants of point prevalence of CMA reported by parents of 4.2% (95 % confidence interval (CI): 3.2-5.4), decreasing to 2.0% (1.5-2.5) when CMA was proven with a double-blind placebo-controlled food challenge (DBPCFC). CMA manifests through diverse...

IBS Skin Patch Test Food Allergy Study
Participants with IBS are skin patch tested (no needles) to 80 different foods and food additives, compounded for patch testing, in search of food allergies. The testing requires 3 office visits within a 4 or 5 day period. The patches are taped to the back at Visit #. At Visit #2 48 hours later, the patches are removed from the skin and the outside border of each patch is marked with a felt tip marker. At Visit #3 (final visit) 1 or 2 days later, the patch test reading is performed by the doctor-investigator. An allergy is identified as a small red mark where the food was in contact with the skin for 48 hours. Those participants ...

Immune-supportive Diet and Gut Permeability in Allergic Children
Peanut and nut allergy can be life threatening. Some patients have very low threshold levels (i.e. the amounts of peanut and nuts to which the patients react), others react to higher doses. The reasons for these differences in threshold are not well understood. Patients with peanut and nut allergy often suffer from other allergic diseases (atopic dermatitis, hay fever and asthma). A disturbed gut microbiota composition and an increased gut permeability may explain the development of allergic disease. We hypothesize that increased gut permeability is related to low threshold levels to peanuts or nuts. In addition, as it is known that...

Immunoglobulin G4 and Immunoglobulin E Antibodies in a Population With Adverse Reactions to Foodstuffs-related Symptoms
The aim of this study is to analyze a population with symptoms associated with adverse reactions to foodstuffs (ARFS). To determine the levels of food-specific immunoglobulin G4 (IgG4) and immunoglobulin E (IgE) antibody reactions (AbR).

Indiana University Gastrointestinal Motility Diagnosis Registry
Develop a registry (list of patients) with accurate clinical motility diagnosis. This registry will help the doctors to identify the patients with specific disease conditions. It will also help in promoting future research in gastroenterology motility disorders

Induction of Sustained Unresponsiveness to Peanuts Using High- and Low-dose Peanut Oral Immunotherapy
This study is a continuation of a clinical trial NCT044155930 comparing the efficacy and safety of oral immunotherapy (OIT) with low or high doses of peanut protein (150 or 300 mg, respectively) and will involve patients who have accomplished their per-protocol participation in that trial. The aim of current study is to assess a sustained unresponsiveness (SU) to allergen protein after at least 8 months of previously assigned high- or low-dose peanut OIT, followed by 4-week-allergen avoidance, and verified by an open oral food challenge (OOFC).

INhaled Salbutamol vs Placebo for the Treatment of Acute IgE-mediated Abdominal Pain From Allergic Food REactions
The goal of this study is to assess the efficacy of inhaled salbutamol to treat abdominal pain during food allergic reactions. Patients experiencing abominal pain as a result of a food allergic reaction during a food challenge in the allergy clinic will be invited to participate to the study. They will receive either 8 puffs of salbutamol (asthma inhaler) or 8 puffs of a placebo inhaler. The abdominal pain will then be followed using a numeric scale to see if patients receiving the medication experienced a faster improvement compared to those receiving the placebo.

Intralymphatic Immunotherapy Enhanced by Vitamin-D, a Randomized Placebo-controlled Trial and Comparison With SLIT
A national, multicenter, randmised double blind study with parallell arms. 360 patients with grass induced allergic rhinitis will be open randomised 1:2 to 3 years Grazax sublingual immunotherapy or 3 intralymphatic injections with ALK Alutard Timothy. In a second step, the ILIT group will be double blind randomised 1:1 to an intramuscular injection of Vitamin D Vicotrat or placebo, 4 week before the start of the intralymphatic treatment. The primary outcome measure is daily combined symptoms and medication scores during grass pollen season.
