Atopic eczema is also known as atopic dermatitis. This condition is common and inflammation of the skin causes a dry and itchy rash. It usually starts in infancy and childhood, but can also occur in adults. In infants, the face and outer side of the limbs are affected but during childhood, it usually affects the neck and skin folds. In mild eczema, the rash is red, dry and itchy. If the condition worsens, there may be oozing, crusting and bleeding. The itch can be severe enough to interrupt sleep.
Genes play an important role as atopic eczema often runs in families. Patients also have a tendency to develop other hypersensitivity disorders such as asthma, allergic rhinitis or hay fever.
In atopic eczema, the immune system is altered and overreacts to things such as irritants (eg soaps, fragrances, detergent), and allergens (eg house dust mites, animal dander). In addition, an impaired skin barrier also contributes to dryness and increased penetration of allergens and bacteria/viruses.
No, it is not infectious and you cannot spread it to other people.
In general, atopic eczema tends to improve as the child gets older and 50-75% may clear in the teens. However, eczema may still occur on and off at times, even in adulthood. Good skin care and use of appropriate medications is important to minimise these occurrences.
In adults, food allergies causing eczema is uncommon.
The prevalence of food allergies is highest in young children less than 3 years old with severe eczema. It may be suspected if eczema is difficult to control or rashes appear after eating a specific food. Common food allergens in children include cow’s milk, hen’s egg, peanut, tree nuts, shellfish, wheat and soy. Tests for food allergies are available, speak to your dermatologist regarding these tests.
