Introduction Atopic dermatitis, also referred to as atopic eczema, infantile eczema, allergic eczema, disseminated neurodermatitis, and prurigo Besnier, is a common and important cause of morbidity in children of all ages. A total of 22% of patients seen in pediatric dermatology clinics have atopic dermatitis. In 1969, Wingert et al reported that 4% of pediatric emergency room visits at the Los Angeles County General Hospital were due to atopic dermatitis, and this did not include patients seen for impetigo, a common complication of atopic dermatitis. The prevalence of atopic dermatitis in the pediatric population has increased over the past 3 decades from 3% to 10%, and it appears to be even higher in heavily populated urban areas. Pediatricians, therefore, must understand its pathogenesis and management. Epidemiology Sixty percent of children who have atopic dermatitis manifest their disease in the first year of life; 90% do so by age 5 years. A genetically prone individual may not manifest the disease until exposed to a particular environmental situation. Onset has been associated with relocation from a rural to an urban location or from a region of high to low humidity. The course of adopic dermatitis is difficult to predict, although one 15-year longitudinal study revealed that the disease persisted in 60% of cases.

Background: Allergic rhinitis is one of the most frequent chronic diseases among children. The objective of the study was to assess the prevalence of and the factors associated with self-reported allergic rhinitis symptoms in schoolchildren from Bogota, Colombia. Methodology/principal: We followed the International Study of Asthma and Allergies in Childhood (ISAAC) methodology. Our sample included 3,256 children aged 6 - 7 and 3,830 adolescents aged 13 - 14 years. Results: The prevalence of self-reported allergic rhinitis symptoms was 30.8% among children and 36.6% among adolescents. Factors associated with self-reported allergic rhinitis among children included current asthma and atopic dermatitis symptoms; use of acetaminophen in the first year of life and in the last 12 months; antibiotic use in the first year of life; high- school and university maternal education; smokers at home; and caesarean delivery. Among adolescents, associated factors included current asthma and atopic dermatitis symptoms; current acetaminophen use once per month; frequent fast-food consumption; cat exposure at home; and smoking. Conclusion: Further exploration of factors associated with allergic rhinitis symptoms is needed.

Атопический дерматит – широко распространенный хронический дерматоз мультифакториальной природы с превалирующей долей генетического компонента и сложным патогенезом. В патогенезе атопического дерматита важную роль играет наследственная детерминированность, приводящая к нарушению состояния кожного барьера, дефектам иммунной системы (стимуляция Th2-клеток с последующей гиперпродукцией IgE); гиперчувствительность к аллергенам и неспецифическим раздражителям, колонизации кожи и слизистых патогенными микроорганизмами, а также дисбаланс вегетативной нервной системы с повышением продукции медиаторов воспаления. К генетическим факторам развития атопического дерматита относят наличие мутации гена филаггрина, приводящей к нарушению функции эпидермального барьера при атопическом дерматите, а также семейный анамнез атопического дерматита и других атопических заболеваний. С дефектами иммунной системы связано развитие воспалительной реакции в коже с участием Т-лимфоцитов. В острую фазу заболевания преобладает Th2-ответ, когда происходит стимуляция Th2-клеток с последующей гиперпродукцией специфических IgE; в хроническую – происходит переключение с Th2- на Th1-иммунный ответ. В патофизиологические механизмы атопического дерматита вовлечены ряд интерлейкинов и ИФН-γ, которым для передачи сигнала требуется участие внутриклеточной сигнальной системы JAK/STAT, в том числе Янус-киназы 1-го типа. Заболевание развивается обычно в первые 2 года жизни и в 2/3 случаев сохраняется во взрослом возрасте, при этом 45% всех случаев начала заболевания приходится на первые 6 месяцев жизни: в 60% случаев заболевание развивается в течение первого года жизни и в 85% случаев в возрасте до 5 лет. В зрелом возрасте кожный процесс сохраняется у 38-42% больных. С течением времени подходы к терапии дерматоза претерпевали значительные изменения. В настоящей статье приведен актуальный обзор результатов клинических исследований препарата упадацитиниб в лечении больных атопическим дерматитом взрослых и подростков. Atopic dermatitis is a common chronic dermatosis of multifactorial nature with prevalence of genetic component and complex pathogenesis. In the pathogenesis of atopic dermatitis, an important role is played by hereditary determinism, leading to a violation of the state of the skin barrier, defects of the immune system (stimulation of Th2 cells with subsequent overproduction of IgE); hypersensitivity to allergens and nonspecific irritants, colonization of the skin and mucous membranes by pathogenic microorganisms, as well as an imbalance of the autonomic nervous system with an increase in the production of inflammatory mediators. The genetic factors for the development of atopic dermatitis include the presence of a mutation in the filaggrin gene, leading to dysfunction of the epidermal barrier in atopic dermatitis, as well as a family history of atopic dermatitis and other atopic diseases. The development of an inflammatory reaction in the skin with the participation of T-lymphocytes is associated with defects in the immune system. In the acute phase of the disease, the Th2 response predominates, when Th2 cells are stimulated with subsequent overproduction of specific IgE; in chronic – there is a switch from Th2- to Th1-immune response. A number of interleukins and IFN-γ, which require the participation of the JAK/STAT signaling system, including Janus kinase, are involved in the pathophysiological mechanisms of atopic dermatitis. The disease usually develops in the first 2 years of life, and in 2/3 of cases persists into adulthood, while 45% of all cases of onset of the disease occur in the first 6 months of life: in 60% of cases, the disease develops during the first year of life and in 85% cases under the age of 5 years. In adulthood, the skin process persists in 38-42% of patients. Over time, approaches to the treatment of thedermatosis have undergone significant changes. This article provides an up-to-date review of the results of clinical trials of the drug upadacitinib in the treatment of atopic dermatitis.

Background. Atopic dermatitis (AD) prevalence may be compared in cohorts evaluated with standardized questionnaires. The prevalence of AD in Russia with the UK Working Party’s Diagnostic Criteria for Atopic Dermatitis was not tested yet. Objective. To estimate AD prevalence in a population of Moscow 1-year old children with the UK Working Party’s Diagnostic Criteria for Atopic Dermatitis Methods. A population cohort of 393 children was recruited in Postnatal Department of Moscow No.1 Maternity Hospital in 2011. One year later 363 mothers (92,4%) were questioned with the UK Working Party’s Diagnostic Criteria for Atopic Dermatitis. Cheeks/body hyperemia and/or skin rash were also estimated in 365 families in connection with food intake by a child or by his mother during breastfeeding. Sensitization at the age of one was investigated in 130 children. Results. The UK Working Party’s Diagnostic Criteria for Atopic Dermatitis diagnosed AD in 2,2% children (8 of 363). One or more episode of cheeks/body hyperemia and/or skin rash during the first year of life was in 45,75%. 5,38% of children were sensitized. Conclusion. A few amount of one year old children Moscow population is diagnosed with AD according to the UK Working Party’s Diagnostic Criteria for Atopic Dermatitis, especially in compare to the number of children with skin reactions to the dietary intake.

Nummular (coin-shaped) and classical (flexural) atopic dermatitis differ morphologically, but no other distinguishing features are known. The aim of this study was to determine differences and similarities of both variants in children. Detailed interviews, clinical examinations, biophysical measurements and electron microscopic analyses were performed on 10 children with nummular atopic dermatitis, 14 with classical atopic dermatitis and 10 healthy controls. Nummular atopic dermatitis affected more boys than girls and manifested less frequently within the first year of life than classical atopic dermatitis. Localization, distribution and morphology of the eczema varied more over time, and expression of keratosis pilaris was more severe in children with nummular atopic dermatitis. Both disease groups showed reduced hydration, increased transepidermal water loss and reduced intercellular lipid lamellae in lesional skin areas compared with non-lesional areas. These findings underline the separate classification of both variants. Further research is necessary to investigate the potential of diverging therapeutic approaches.
