Correlation between clinical and immunological findings in atopic dermatitis.

Many immunological alterations have been reported in atopic dermatitis, and it is likely that in some cases they are capable of worsening the clinical course of atopic dermatitis (AD). More frequently these alterations are responsible for conditions associated with AD such as asthma, food allergy and infections. It seems probable that in some cases they are evidence of a preclinical allergic manifestation. However, in most cases, it is likely that the immunological alterations do not affect significantly the clinical course of the disease.
