Proper hydration of the skin in infants could be used to prevent the development of atopic dermatitis in children at risk for genetic predisposition to allergic diseases. So believes the Spanish Society of Clinical Immunology, Allergy and Asthma Pediatric (SEICAP) that, on the occasion of the Day of Atopic Dermatitis held on Monday November 27 , warns of the importance of hydrating the skin of newborns to strengthen the skin barrier, as well as the entry of allergens and development of this disease would be avoided, as has been shown in some preliminary investigations.
Atopic dermatitis is an inflammatory process of the dermis characterized by intense pruritus, dry skin, with a chronic evolution and studies in outbreaks. It can occur in individuals of all ages but is more common in children. In fact, 50 percent of cases are diagnosed in the first year of lifeand in Spain, the prevalence is between 6 and 15 percent, according to the SEICAP. “It is a disease with a genetic, modulated by climatic factors and predisposition that carries immunological disorders. However, recent research suggests that from birth, could minimize the risk of atopy and get the child does not develop chronic illness, “says Maria Teresa Guerra, coordinator of the Working Group of Atopic Dermatitis and Skin Allergy.
All children with atopic dermatitis have especially dry and permeable skin. “This facilitates the penetration of multiple environmental allergens” explains Dr. Escarrer. On the other hand, we must bear in mind that the damaged skin eczema has 30 percent fewer ceramides , which in turn influences dryness and the alteration of the barrier function. ” It is important that pediatricians insist on maintaining the integrity of the skin barrier to hydration therefrom by emollients” he says. A review of studies published in this month Allergology International confirms that the skin barrier dysfunction is one of the predisposing to the development of allergic skin diseases such as atopic dermatitis factors.
“Clean and moisturized”
Therefore, Guerra says, “if we take care of the newborn skin from day one , keep it clean and moisturized, and continue habits that prevent dryness, we will slow the progression of the disease in infants at risk of atopy.” Thus, research published this month in Advances in Therapy concludes that using a moisturizer that contains ceramide, along with the body wash in children, delayed exacerbations of atopic dermatitis in two months and produces a high patient satisfaction .
Another paper published in Current Pediatric Reviews concludes as the use of an emollient in children with this disease improve significantly the affected area, the intensity and severity of the same fam a. Other care are directed to the use of cotton or linen and no detergent soaps for washing, the use of mild soaps, with acidic or neutral pH, bath, keep the house clean of dust or protect the skin from the cold during the winter.
Three factors involved
At the origin of atopic dermatitis involves three factors acting consistently and contribute to its chronicity and severity. “On one hand, influences genetic predisposition because there are many mutations in genes that alter the skin barrier and cause a permanent inflammation ” said Mercedes Escarrer SEICAP president. Also involved dysfunction of the skin barrier, “which facilitates entry of allergens, irritants and pathogens” added. Finally, a persistent inflammation of the dermis with inflammatory infiltrate, responsible for the chronicity occurs.
At present, says this specialist, “all skin diseases fret and worry parents of our young patients who always look for a causal relationship and, in the case of atopic dermatitis, it is often not possible to find” . Therefore the study and diagnosis of children must be comprehensive by the allergist pediatrician, “before removing foods from the diet, which will not yield results in terms of improvement of eczema and may result in deficiency diets , ” he says.
