Atopic dermatitis is an incurable, but relatively easily treatable skin disease. It is chronic in episodes and is not contagious. The word “atopic” means that the skin is prone to allergic reactions and is overly sensitive.
Symptoms include red, flaky skin, severe itching, and oozing skin changes. It can vary in strength and is also dependent on age. Patients who are affected by atopic dermatitis are more likely to suffer from other allergies, such as hay fever. The therapy of the skin disease usually consists of anti-inflammatory creams.

The causes are complex and not yet fully understood. It is believed that there is not just one cause, but that a combination of many factors causes atopic dermatitis. According to experts, genetic factors, changes in the immune system and environmental influences play a role.
The word “atopic” comes from the Greek and means something like “wrongly in place” or “extraordinary”. Experts understand it to be an excessive immune reaction to certain stimuli, called trigger factors. Various substances can cause an allergic reaction.

The triggers are different from patient to patient and must be for each patient differently to be determined.
While the trigger factors can be easily determined, a genetic cause difficult to prove. Many genes in the development of the disease have been classified as "suspicious", but it is difficult to determine which gene is the cause of atopic dermatitis. Studies show that the genetic defects lead to a disturbed skin barrier lead and the skin thus becoming more susceptible to environmental factors / allergens.
In Europe the frequency is approx. 5-20% in childhood and becomes less common with old age. 90% of all patients develop the disease before the age of five.
Usually the disease gets better with age and therefore only complain in adulthood 30% of all those affected about symptoms. Compared to 60-70 years ago today, atopic dermatitis occurs four times more often.
The reasons are not entirely clear. Possible causes are one better hygiene and called changed circumstances. It is clear that children who grow up on a farm have fewer allergies than children who grow up in the city. This phenomenon is due to the lack of exposure of bacteria related.
Symptoms vary slightly based on age. A so-called cradle cap is often noticeable in infancy. The name refers to the appearance of the scab. Cradle cap is a crusty, white rash on the child's scalp. Infants can also find areas of oozing skin, scaly, whitish skin and scratch marks. In older children there are scaly, whitish patches of skin, especially on the crooks of the arms and the back of the knees, as well as on the hands and neck area. The skin is thickened in some places and looks rough. The children also complain of itching and dry lips, as well as tears in the skin on the mouth and earlobes.

Bacteria can easily penetrate through the open, torn areas of skin and thus trigger inflammation.
The symptoms hardly change in adulthood. Here, too, the flexors of the arms and legs are particularly affected. The bad itching is often felt to be the main symptom. It is triggered by the injured, irritated skin. However, scratching the skin creates a vicious circle, because scratching creates new skin irritations, which in turn promote itching. The itching is particularly annoying at night, and many patients complain of lack of sleep and fatigue. This also often represents a psychological burden for the patient, since he no longer feels efficient. Some people affected also suffer from social exclusion and decreased self-confidence. Children in particular react to their symptoms with increased stress, which, however, can again be a trigger factor.
Other symptoms include paleness around the mouth, a double crease in the eyelid, skin inflammation on the nipples, and a whitish skin reaction after scratching (Demographism).

Often the cracked skin areas are colonized by the bacterium Staphylococcus aureus. These bacteria worsen the symptoms and intensify the disease process. Fungi also feel good in the affected skin areas and can lead to inflammation. Infection with the herpes virus occurs less often. If the skin becomes infected with this virus, eczema herpaticum can occur, which can often only be treated in hospital.
