The search for factors affecting the efficacy of bronchial asthma (BA) therapy in children is an actual problem. subject of many modern scientific studies. Authors note that adherence to therapy in patients with asthma ranges from 30 to 70%. Often this index does not exceed 50%. Analysis of adherence to medical recommendations in children with asthma and the search for compliance reduction factors is one of the ways for optimizing therapy and improving the quality of life for children with asthma.Purpose. In order to optimize bronchial asthma therapy in pediatric practice, we analysed adherence to medical recommendations and its effect on the controllability of the disease in children with asthma.Materials and methods. The study included 94 children aged 6 to 17 years with an established diagnosis of bronchial asthma. All patients had previously been recommended basic therapy in the form of inhaled glucocorticosteroids (ICS) or their fixed combinations with long-acting beta2-adrenomimetikami (LABA). An assessment of BA control symptoms was carried out, and factors affecting adherence to medical recommendations were analyzed. The effect of decreased patient compliance on the control of asthma symptoms was evaluated.Results. 61.7% of children with asthma have insufficient disease control. In 42.55% of patients, a survey revealed insufficient adherence to medical recommendations. 88.3% of children and their parents reported the presence of factors capable of influencing the decrease in compliance. The most frequently occurring factor in reducing adherence to therapy turned out to be insufficient patient awareness of the disease itself, the mechanisms of therapy action, and the prospect of treatment. Statistical data processing showed a statistically significant decrease in adherence to medical recommendations in the group of patients with insufficient asthma symptom control (p = 0.038).Conclusion. Only 38.3% of children had complete asthma symptom control. The statistically significant reduction in adherence to medical recommendations in the group of children with insufficient symptom control suggests the need for educational activities for children with BA and their parents in order to increase adherence to medical recommendations, optimize the effectiveness of therapy and improve the quality of patients’ life.

Previous pharmacogenetic studies demonstrate significant genes’ polymorphisms effect on the efficacy and safety of pharmacotherapy, including in bronchial asthma (BA). According to the literature, there are data on the effect of polymorphisms CYP3A4*22 and CYP3A5*3 on the efficacy of inhaled corticosteroids in children with BA. Further research on the effect of pharmacogenetic features on the efficacy and safety of drugs is one of the way to optimize asthma therapy in children.Purpose. Identification of possible ways to optimize asthma therapy by the analysis of CYP3A5 (A6986G) gene polymorphism effect on the asthma therapy efficacy.Materials and methods. The study was conducted on the basis of three children’s polyclinics of Moscow. 100 children aged 6–17 years with an established diagnosis of BA were included. Dynamic assessment of asthma control and the amount of therapy needed was carried out. All patients underwent genotyping for the A6986G polymorphism of CYP3A5 gene by real-time PCR. Statistical data analysis was carried out using a programming language for statistical data processing R.3.4.0.Results. It was found that 8% of children with asthma were heterozygous for the A6986G polymorphism of the CYP3A5 gene, 92% of respondents were homozygous with the GG genotype. In 6 out of 8 heterozygotes, the amount of control therapy corresponded the third and fourth therapy stages according to GINA criteria. In the group of moderate and severe BA, the number of heterozygotes for the A6986G polymorphic marker of the CYP3A5 gene was statistically higher compared to the group of children with mild BA (p = 0,048).Conclusion. Thus, we identified a statistically significant difference in the occurrence of heterozygotes for the A6986G polymorphism of the CYP3A5 gene between groups of children with mild asthma and patients with moderate and severe asthma. The AG genotype and the presence of the A allele (CYP3A5 gene (A6986G)) are associated with more severe BA and the need for more anti-inflammatory therapy.

Atopic dermatitis (Ad) is a multifactorial skin disease. As shown by recent studies, a significant role in the pathogenesis of atopic dermatitis is a disturbance of the structural elements of the skin barrier, which contributes to skin xerosis, increase of its permeability to allergens and development of chronic inflammation. As a result, an allergic inflammation develops in the skin. Accordingly, in the treatment of atopic dermatitis great attention should be paid to effective external therapy. In the period of exacerbation of the skin process effective and safe external preparations are drugs of activated zinc pyrithione (APTS) - a line of Skin-Cap products. Use of APTS in atopic dermatitis in children leads to a significant reduction in the severity of inflammation, reduction of the area of skin lesions and severity of symptoms, reducing the need for additional administration of antihistamine and anti-inflammatory drugs, allowing you to reach persistent clinical remission.

Skin diseases in children during the first year of life is a relevant topic for both pediatricians and parents. Absence of knowledge on appropriate care coupled with anatomical and physiological characteristics of baby's skin are risk factors for skin diseases in this group of patients [1, 5]. This is demonstrated by the increased incidence of skin diseases in children, which also encourages further study of mechanisms of skin protection from aggressive environmental factors [1, 11, 7]. This awareness helped to define the key priorities in the treatment and prevention of dermatological diseases in pediatrics.
