Active clinical trials for "Hypersensitivity"

Study the causative insect by skin prick test and sIgE to wasp, bee and fire ants are important but false positive by crossreactivity can occur. sIgE to recombinant venom allergen is proposed to help in finding the causative insect.

In this study, we will be comparing two approaches to the femoral block. The first or classical approach and one that is the most popular in our institution is used by combining ultrasound guidance and neurostimulator to do the block. The second is performed with the ultrasound alone aiming at the inferolateral aspect of the femoral artery with the needle and injecting. The primary endpoint of the study is the sensitive cutaneous block distribution using both techniques.

The purpose of the study is to identify prognostic markers and possible success rate of tolerance induction to peanut allergens in children allergic to peanut.

Patients consulting in the Allergy Unit of the Arnaud de Villeneuve Hospital for whatever suspicion of allergy were asked to participate in the study. Besides a standard battery of respiratory allergens, native raw and cooked potato were tested by means of the prick to prick method, using a metal lancet.

To compare the use supplementation based on green banana flour versus placebo in the insulin sensitivity on individuals who have prediabetes.

Treatment of Dentin Hypersensitivity Using Theobromine , Remin Pro , and Combination of Both Materials

The trial compares patient-reported postoperative sensitivity of 2 existing dental filling materials. The dental filling materials will be used according to manufacturer's instructions and within the existing CE marked licence. We are interested in investigating which licensed material confers the least postoperative discomfort to our patients in normal clinical use.

All children from 1 to 8 years of age, diagnose with nephrotic syndrome for the first time will be divided into two groups. One group will be given steroids for 12 weeks and other group will receive steroid for 20 weeks. During the 1 years after completion of steroid course patients will be monitor for the episodes of relapse in both group.

Child food allergy represent 6 to 8% of child in industrialised country. Within this allergy, peanuts and egg allergy are one of the most common. Actually when there is a suspicion of food allergy, the OPT is the gold standard for the diagnosis. During the OPT we give increasing doses of the allergen to the patient and evaluate threshold causing a clinical reaction. This test is associated with a risk of strong allergic reaction and need a medical supervision. Standard allergy test, like skin test or specific IgE test, can't be use for the diagnosis of these allergy. Some publications demonstrate that these tests lack sensibility and specificity for child food allergy diagnosis. New tests have to be develop to diagnosis child food allergy without risks. The BAT is a cellular test able to evaluate the basophiles activation by specific allergen in vitro. This test allow us to evaluate more physiologically the sensitization of patients to an allergen. It is already used in drug allergy and it has been evaluated in infant milk allergy in an other clinical trial. In this study we want to evaluate the sensitivity of BAT to the diagnosis of child food allergy compare to the gold standard test OPT. We will evaluate the BAT on 140 children with food allergy and compare this results with the OPT at the same time. If the BAT results can predict the sensitivity of children to food allergen, it could limit the use of the OPT and reduce the risk of this test.

This study is designed to determine whether Asians who are especially sensitive to alcohol exposure can be protected by boosting their activities of an alcohol disposing enzyme. This will be accomplished by administering broccoli sprouts that are rich in an agent that increases protective enzyme activity. The test system involves applying alcohol patches to the skin and measuring skin redness.
