Although the oral treatment seems to work, an analysis of the results from 12 clinical trials finds kids who got an immunotherapy have a greater rate of serious reactions.

High salt concentrations are present in the affected skin of people with atopic dermatitis and promote the differentiation of the T helper cells involved in the development of allergic diseases.

A study finds the effect is dose-dependent, with each additional pet further lowering the odds of developing allergies.

Scientists are beginning to unravel the ways in which we develop a healthy relationship with the bugs in our bodies.

Four years after taking a probiotic and peanut protein for 18 months, two-thirds of children in a small clinical trial can eat peanuts with no health issues.

In the 1960s, immunologists took matters into their own hands—and under their own skin—to characterize an immunoglobulin involved in allergies.

In light of recent allergen-exposure studies, an agency-sponsored panel has formally recommended early introduction of peanuts in an effort to prevent potentially life-threatening allergies.

Egg and peanut consumption during infancy is linked to lower risk of allergy to those foods later in life, according to a meta-analysis.
