Atopic dermatitis is one of the most common chronic diseases in children. But many adults are also affected. There is no cure for the disease. But there are many ways to get along well with her. And it's not uncommon for the itching to suddenly stop on its own.
The skin is dry and sensitive, becomes red, develops flakes—and itches: a typical case of atopic dermatitis. And this is despite the fact that Angela is very conscientious when it comes to her personal hygiene. Applying lotion after her daily shower is part of her routine. She’s able to keep her dermatitis somewhat under control, but when the air is very dry, she still experiences recurring flare-ups.
“Unfortunately, this is a very typical case,” says Claudia Lang. The dermatologist-allergist specializes in neurodermatitis, also known as atopic dermatitis, and conducts research on the condition. “This is often frustrating for patients. We are now much better able to help, but even today, there is no cure for the disease.”
Genetic predisposition
Atopic dermatitis is very common among children and adolescents worldwide; nearly one in five children is affected. It often continues to develop into adulthood. But even so, about five percent of all adults in Switzerland continue to suffer from this inflammatory skin condition. The diagnosis is made based on the clinical presentation: Does the location of the affected areas match? Does the disease progress in episodes? Is it chronic? Do you have itching? The exact cause remains unclear. Not least because various factors often come into play. However, there is a genetic predisposition to developing atopic dermatitis. “We now know that in a great many of these patients, a protein that is supposed to hold skin cells together is altered,” explains Claudia Lang. “You can think of it like a wall: the bricks are the skin cells, and the mortar between them is held together by the protein. If this protein is defective, the entire wall begins to crumble and becomes porous.”
Impaired protective function
Using this image, the specialist tries to explain to the affected person what is happening to their skin. The consequences are serious: The skin becomes dry and brittle. On the one hand, this causes itching. Because the substance that acts as a sealant or mortar between skin cells is missing, the skin also loses its protective function, making it much easier for pathogens or allergens to penetrate. They trigger local inflammation, which further intensifies the itching. And depending on the pathogen, inflammatory atopic dermatitis can quickly turn into an infected form—for example, due to a herpes infection. “This makes consistent skin care all the more important,” emphasizes Karin Grando, a skin care specialist in dermatology. She explains the prescriptions to each patient in detail and tells them how to use each product. “Applying moisturizing products several times a day is the key to success.”
