Summary The history of 188 Caucasian patients with atopic dermatitis (AD) and of 2,151 family members has been analyzed. Of the AD patients 48% suffered from respiratory atopy (36% rhinitis, 28% asthma, and 15% both). AD showed by far the earliest onset of all atopic diseases: 50% of our patients had skin lesions before the age of 2 years and 60% before the age of 5 years. In contrast, symptoms of allergic asthma developed in 40% of AD patients before the age of 5 years in comparison with only 25% who had allergic rhinitis. AD affects females more frequently than males (male to female ratio 1∶1.5), regardless of whether additional respiratory atopies are present or not. In contrast, respiratory atopies develop more frequently in males than in females (male to female ratio 1.5∶1). Mothers with respiratory atopy more often have atopic children (26%) than do fathers with respiratory atopy (13%). Finally, risk figures for genetic counselling are given. In short, the general risk of developing AD (3%) and atopy (7%) increases by a factor of two with each first-degree family member already suffering from atopy.
