All of the following statements regarding atopic dermatitis are true except (AIIMS May 2013)
|A||80% of children with atopic dermatitis also coexpress allergic rhinitis or asthma.|
|B||Exacerbations and remissions are typical.|
|C||Patients with atopic dermatitis often have increased levels of circulating Ige.|
|D||The adult form of atopic dermatitis is commonly localized to the hands.|
|E||When one parent is affected with atopic dermatitis, there is an 80% prevalence of atopic dermatitis in the children.|
When one parent is affected with atopic dermatitis, there is an 80% prevalence of atopic dermatitis in the children.
1). The clinical course of atopic dermatitis (AD. is characterized by exacerbations and remissions.
2). Lesions are typically pruritic and appear similar to those of eczematous dermatitis.
3). Patients with AD have increased production of IgE and increased serum levels.
4). Delayed-type hypersensitivity reactions, however, are impaired.
5). Most children with AD also have atopy manifested as allergic rhinitis, asthma, food allergies, or eczema.
6). When both parents have AD, >80% of their children will have AD.
7). When only one parent is affected, the prevalence falls to ~50%. Half of all children will continue to suffer with AD into adulthood.
8). The distribution may be the same as in childhood, but more commonly the disease becomes localized, such as in hand eczema.
