4.4 Outlook
Future investigations concerned with the effect of early-life eczema on
allergic multimorbidity should consider the integration of disease
severity for eczema, food allergies, asthma and hay fever, since it was
repeatedly shown that eczema severity was associated with the
development and severity of other allergic
diseases.13,18,21,40 Further, there seems to be a
heterogenic association between eczema phenotypes and different
allergenic foods.22 This distinction could result in a
more detailed understanding of the allergen specific associations
present among comorbid allergic diseases, if applied to future studies.
