Active clinical trials for "Hypersensitivity"

To determine the local cutaneous and ocular tolerance of a developmental cosmetic facial serum in healthy females with sensitive facial skin under normal conditions of use.

This study evaluates the addition of three probiotics (Bifidobacterium longum, Bifidobacterium breve and Bifidobacterium infantis) in the treatment of pediatric food allergic children to milk or egg. The allergic participants will receive the probiotics, while other two populations age and sex matched of not confirmed allergic and healthy children will not receive probiotics.

This is a pilot study that provides the investigators with an opportunity to assess the application of PSM technology for patient monitoring in the NICU. This is a prospective, observational, cohort study.The investigators expect the duration of infant participation in this study to be 6 hours per single recording session with no follow-up required.

To confirm the protein expression level in radiation-induced late effects patients and to determine the performance value, in particular the positive predictive value, of a blood test based on the dosage of a panel of five proteins, it is necessary to validate these preliminary results by a prospective study on a large cohort of patients.

This prospective, cross-sectional study is designed to improve understanding of how early-life introduction of peanuts may promote the development of tolerance at 12 years of age and will serve as an additional safety evaluation of this nutritional intervention.

To determine if a brief primary care intervention can educate under-resourced and minority parents about discipline in a way that is culturally sensitive.

This study aims to show whether the hyperglycaemic phases following a treatment with glucocorticoids, as well as blood measurements correlated to high blood glucose levels and insulin resistance, vary significantly between patients with and without gestational diabetes mellitus.

The purpose of this study is to see if the recruitment of a certain cell type (the alpha 4 integrin (CD49d) expressing neutrophil) during a nasal allergen challenge can be inhibited by pretreatment with an FDA approved leukotriene antagonist (montelukast).

The purpose of this patient registry is to demonstrate safety and efficacy of food oral immunotherapy in food allergic patients. Factors that lead to adverse reactions will be identified. The frequency of rescue epinephrine use will be recorded.

An emerging problem in clinical practice is how to manage the growing number of patients who experience symptoms related to the ingestion of gluten-containing foods gluten and in whom celiac disease has been ruled out. These patients most frequently report gastrointestinal symptoms such as diarrhea, abdominal discomfort or pain, bloating, flatulence, but also extraintestinal symptoms, including headache, lethargy, attention-deficit/hyperactivity disorder, ataxia, or recurrent oral ulceration. This heterogeneous syndrome, which has been reported to improve or even disappear after gluten withdrawal and to relapse after gluten challenge, is called non-celiac gluten sensitivity.1 The concept of nonceliac gluten sensitivity is not completely new. Besides several sporadic single cases reported, more than 30 years ago an oral, double-blind, placebo-controlled, cross-over gluten challenge trial showed that six out of eight adult non-celiac patients, who suffered from intestinal symptoms caused by the ingestion of gluten-containing food, were affected by gluten-sensitive diarrhea. Over the last few years, an intense debate about the existence and the prevalence of nonceliac gluten sensitivity has emerged, as shown by the considerable increase in internet forums of discussion on this topic and in availability of gluten-free food. A definition of nonceliac gluten sensitivity based on definitive scientific evidence does not still exist, and the clinical trials conducted so far in order to fill this knowledge gap are burdened by a number of biases. In a cross-over trial of subjects with suspected NCGS, the severity of overall (intestinal plus extraintestinal) symptoms increased significantly during 1 week of intake of small amounts of gluten (daily 4.375 grams), compared with placebo. Among the 59 participants in this trial, the Investigatotors identified only three true gluten-sensitive patients, defined as having a delta overall score -calculated by subtracting the weekly overall score under placebo from that under gluten- higher than the mean delta overall score plus 2 standard deviations. However, these results should be cautiously interpreted due to the lack of a control group of non-gluten-sensitive subjects. On this basis, the Investigators will conduct a randomized, dose-finding, double-blind, placebo-controlled, cross-over gluten challenge trial aimed at comparing the effects of a daily dose of 8.4 grams of gluten with those of a daily dose of 6.0 or 4.2 grams of gluten on a cohort of subjects with nonceliac gluten sensitivity versus healthy volunteers.
