A patch against peanut allergy; tested in the absence of effective treatment
A patch against peanut allergies is being tested in the absence of effective treatment. The patch that contains allergens that arises on the skin to migrate to the lymph nodes gradually makes less sensitive to peanuts.
In France 5-7% of children and 2% of adults suffer from food allergies severe. In the absence of conclusive treatment, a French start-up DBV Technologies has created a patch filled with allergens in the form of dry powder that arises on the skin of the arm.
When the patch is stuck, allergens are released into the skin and migrate to the lymph nodes that stimulate the production of cells making gradually more resistant organism to allergens.
After 18 months, two-thirds of children who experienced this device could eat ten times more peanuts.
The company hopes to market its patches peanuts and cow’s milk protein from 2017. It also prepares an anti-mite patch.
