Sponsor's own description

Atopic dermatitis (AD) is a frequent chronic relapsing inflammatory skin disorder, characterized by intensely itchy eczema. AD usually starts within the first 2 years of life. In 30 - 60% of children, inflammation spreads onto other body surfaces such as the gastrointestinal tract, the respiratory tract, and the conjunctives within a few years. This sequence is called atopic march. Atopic dermatitis and associated atopic diseases are more frequent in families, suggesting a genetic predisposition. However, the underlying factors such as genetic phenotype, environmental factors, or life style which cause or worsen an existing allergic disease are not understood yet. Affected people suffer from recurrent flares that result in significantly impaired quality. This study will collect clinical and laboratory data to elucidate immunotolerance and preventiv stategies with the aim to develop new and individual treatment options of atopic diseases.
