Active clinical trials for "Food Hypersensitivity"

The investigators will conduct low-dose intranasal allergen challenges on children/adolescents with a diagnosis of food allergy to egg/cow's milk/soya/wheat/peanut. The data will be used to determine the safety and potential utility of intranasal food challenges in the diagnosis of food allergy.

Multicenter randomized (1:1) trial of strict avoidance versus sub-threshold dietary introduction of peanut in peanut allergic infants 4-14 months of age who react at a minimum cumulative dose of at least 430 mg of peanut protein at initial oral food challenge (OFC) for 12 months, followed by cross-over to sub-threshold dietary introduction of peanut in those randomized initially to avoidance.

Positive reactions in Atopy patch test in children with food allergy-related gastrointestinal symptoms

The first 1,000 days of life, from the conception to 24 months, are crucial to achieve long-term health outcomes and represent a strategic period to intervene under prevention and public health perspective. Nutritional exposures during this critical period of life can influence the future disease susceptibility. Maternal diet during pregnancy has been linked to offspring overweight/obesity risk and it could represent a potential target for overweight/obesity prevention. The Mediterranean Diet (MD) is considered one of the healthiest dietary models, which impacts beneficially the gut microbiome (GM), providing high amounts of fiber, antioxidants polyphenols and vitamins, and a balanced ratio of essential fatty acids (ω6:ω3). Notably, the MD beneficial effects are due to the synergistic and interactive combinations of nutrients, and the modulation of gene expression through epigenetic changes. Unofrtunately, the MD mechanisms during pregnancy in the prevention of childhood overweight/obesity are not yet fully known.

This is a randomised, open-label, controlled study designed to investigate the effect of short-term neonatal skin barrier protection using a commercially available moisturiser on the prevention of atopic dermatitis and food allergy in high risk children.

Irritable bowel syndrome (IBS) sufferers often find that specific foods can exacerbate their symptoms; identifying which foods involves a long and arduous process. Different food allergy tests are marketed to IBS sufferers and healthcare practitioners as an easy way to identify these offending foods. Which test method might be best to use? This project compares the results of different food allergy methods versus an elimination/challenge diet to determine which method maybe superior in IBS sufferers.

This pilot study will test the use of visual cues to engage food service workers in protecting patrons with food allergies. Food service workers from Philadelphia quick-service restaurants were recruited to participate in a survey of attitudes that includes an embedded randomized experiment testing an experimental cue (photograph of an allergic child) to increase workers' engagement and empathy.

Among the 15 million people with food allergies in the U.S., adolescents experience the highest risk of adverse events. Yet, there are few evidence-based strategies to improve food allergy management in adolescents. In a cohort multiple randomized controlled trial, this study will include two experiments to test the effectiveness of text message reminders and incentives to encourage epinephrine-carrying.

The questioned proposed by this study is one of treatment: "To what extent does simultaneous BMT (Bilateral Myringotomy with Tympanostomy Tubes), adenoidectomy, and diagnosis/avoidance of food allergy affect the frequency of recurrent otitis media (ROM) versus the standard academy approach (tube insertions only) to chronic otitis media with effusion; furthermore, are adenoids a factor in OME or is food allergy diagnosis and treatment able to significantly prevent ROM after the tubes fall out?" The trial seeks to provide evidence that the treatment for Chronic OME in children should involve surgical procedures (BMT +/- adenoidectomy), as well, as a food allergy work-up and subsequent avoidance of the offending foods in order to significantly decrease ROM. To answer this question, a prospective, randomized controlled trial needs to be conducted. Since a majority of OME patients are from the pediatric population, parental consent must be obtained. Subjects in our study will initially present to the clinic with otitis media symptoms and diagnostic tests such as a tympanogram, otoscopy, and history of recurrent otitis media will be obtained. Once the surgical decision for bilateral myringotomy and tympanostomy tubes has been made, parents will be informed about the trial. The standard protocol for children presenting with initial Chronic OME is to perform a BMT. Therefore, data from the control group (Group 1) will be obtained from faculty ENT who follow the academy's recommendations. Data from Group 2 and 3 will be collected from other ENT faculty members, including the faculty co-investigator who will perform the BMT and obtain a food allergy blood draw at the time of surgery. The study's faculty co-investigator will describe food avoidance techniques to post-op patients from Groups 2 and 3. Patients with previous adenotonsillar surgery or placement of tympanostomy tubes will not be enrolled in the study. The incidence of ROM episodes in all trial groups will be recorded.

This study evaluates the effect of a multicomponent intervention applied to restaurant staff about training and nutritional quality of menu improvement, in order to promote a healthy diet and a better management of allergies and intolerances addressed to each family member satisfying the customers with specific needs (allergies and intolerances of food).
