Food Allergy Suspected clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Association Between Asthma and Food Allergy

AAAli

Start date: April 26, 2016
Phase: N/A
Study type: Interventional

Prevalences of food allergies and asthma increased in the population during the last decades. These two pathologies, responsible for a real burden, are often associated and are to be considered as comorbidities; this aspect is more and more studied in the literature and many authors tried to find a link between diets and asthma. The narrow link between these two atopic pathologies and the fact that food allergy can come along with respiratory symptoms also in patients without history of asthma must be better understood, considered into the management of food allergy. The main objective of this study is to study the prevalence of signs and/or symptoms suggestive of bronchial hyperreactivity, during an oral food challenge (OFC) in patients older than 5 years. The secondary objective is to study the risk factors to develop asthma during a food allergy reaction. This historical-prospective single center study , was realized in the Allergy Unit of the University Hospital of Montpellier. All the patients having been hospitalized for a positive OFC between January, 2001 and January, 2016 were included. The diagnosis of asthma was established according to the recommended international clinical and physiological criteria. Prevalence of bronchial hyperreactivity during OFC among those with positive OFC, was calculated. The search for risk factors was made by a logistic regression univariate then multivariate, completed by a decision tree.
