Filter by:The purpose of this study is to determine if children with egg allergy can be desensitized to egg protein and if this desensitization can help them outgrow their egg allergy at an earlier time than normal. Our hypothesis is that children with egg allergy can be orally desensitized to egg protein and that this desensitization will help them outgrow their egg allergy at an earlier time than normal.
The purpose of this study is to evaluate the safety and immune response to daily sublingual (under the tongue) immunotherapy (SLIT) with peanut extract in adults and children with peanut allergies.
Milk is the among the most common food allergens in infants and children. The majority of children outgrow their allergies; however, the exact mechanisms by which food tolerance is achieved are unknown. Strict avoidance of the offending food is currently the only known therapy. However, subjects have been known to lose food hypersensitivity while frequently ingesting small amounts of processed forms of the offending product. The purpose of this study is to investigate whether ingestion of small amounts of processed milk protein will be permitted without compromising the chances of either outgrowing milk hypersensitivity or prolonging the time needed to achieve clinical tolerance.
This study will evaluate and follow patients with various allergic, hypersensitivity and inflammatory disorders. The protocol is not designed to test new treatments; patients will be managed with standard of care therapies. Participants may be referred to other current NIAID protocols as appropriate or to new studies as they are developed, but will not be required to join another study. Patients with allergic, hypersensitivity or inflammatory disorders between the ages of 3 years and 80 years may be eligible for this study. Conditions of interest include, but are not limited to, asthma, allergic rhinitis, mastocytosis, atopic dermatitis and food allergy. Participants will have a medical history and physical examination, plus standard tests for diagnosing and treating their specific disorder. Tests may include routine blood and urine studies, X-rays or other imaging studies, allergy skin tests and lung function tests. Blood samples may be collected for research on immune system cells and other substances involved in immune function. Generally, about 2 to 6 tablespoons will be drawn at a time, but no more than 16 ounces will be collected over a 6-week period. NIH does not provide emergency medical treatment or treatment for other, unrelated conditions the patient may have. Therefore, patients must maintain a personal physician for these purposes.
The purpose of this study is to determine if oral immunotherapy (OIT) will desensitize a child with an allergy to egg and eventually lead to the development of tolerance to egg.
An increasing number of people have an allergy to birch pollen, which manifests itself as Springtime hayfever. Some will also have cross-reactions to fruits, vegetables and nuts, a condition known as Oral Allergy Syndrome (OAS). Research has demonstrated that the most effective method of diagnosing this problem is by taking a good clinical history and performing skin prick tests using fresh foods. The aim of the study will be therefore to investigate the prevalence of OAS in a birch-sensitive population using a simple screening tool and establish the range of foods involved. The objective will be to maximise effective treatment for the patients in our large respiratory allergy clinic by using the screening tool to identify patients with OAS and advise them on the usual foods involved. A further objective will be to use the data to discover if there are any patterns of particular foods involved in OAS in UK sufferers. The study hypotheses are therefore that there is a high prevalence of oral allergy in people with birch pollen allergy; the best way of diagnosing the problem is by using a screening tool and that there is a core set of foods that are commonly involved in OAS in patients seen in the allergy clinic.
The purpose of this study is to observe the natural course of food allergy, including both the development of peanut allergy in infants at high risk for developing this allergy, and the resolution of both egg and cow's milk allergy.
This study will evaluate whether early exposure to peanuts promotes tolerance and provides protection from developing peanut allergy in children who are allergic to eggs or who have severe eczema. This study has been continued into the ITN049AD (LEAP-On) Study (NCT01366846).
The aim of the study is to find out if allergic diseases can be prevented buy giving probiotic bacteria to pregnant mothers and their newborn infants
1. Purpose of this study is to determine whether NAET procedures are effective in the treatment of children with allergy-related autism spectrum disorders in restoring their verbal and nonverbal communication. 2. Hypothesis: Children in the experimental group will show a significant improvement over the control group in verbal and nonverbal communication as most food allergen groups, environmental allergen groups, childhood immunizations, and some other relevant allergenic substances are desensitized in a systematic way using NAET® procedures within the specified period of study.
