Atopic dermatitis linked to potential progression of allergic diseases

Atopic dermatitis, an inflammatory skin condition often appearing in early childhood, may be linked to the subsequent development of other allergic conditions such as food allergies, allergic rhinitis, and asthma. This progression is referred to by specialists as the ‘atopic march’. While not every child with eczema will develop these conditions, experts suggest a common mechanism involving type 2 inflammation of the immune system may play a role in both skin and respiratory issues.

In Colombia, prevalence rates for atopic dermatitis are reported at 20.9% for children aged 6 to 7 and 24.6% among adolescents. Medical professionals emphasize that early and sustained control of the disease is a critical clinical goal, though research continues into whether early intervention can modify the natural history of the atopic march.

Dermatitis generally manifests through symptoms such as itching, dryness, swelling, rashes, blisters, or scaling. Common types include atopic, contact, and seborrheic dermatitis. Medical consultation is recommended if symptoms interfere with daily activities or sleep, or if signs of infection—such as pus or yellowish crusts—appear.
