The objective was to study the species diversity and the proportion of lipophilic yeasts of the genus Malassezia on the skin of children with atopic dermatitis and control groups, to evaluate age-related features and clinical significance of sensitization to Malassezia and IgE-antibodies to Mn-SOD in children with atopic dermatitis. Materials and methods. The study involved 144 children aged between 1 -14 years: 93 patients with atopic dermatitis, a control group of K1 - 24 children with asthma and /or AR without atopic dermatitis and K2 - 27 healthy children without skin diseases. The yeast Malassezia spp. identified by morphological and physiological characteristics and analysis of the nucleotide sequences of the D1/D2 region of 26S (LSU) rDNA. For detection of IgE antibodies to various allergens, including Malassezia, used the device and reagents ImmunoCap (Thermofisher, Sweden); IgE-antibodies to Mn-SOD was detected by the method of ISAC ImmunoCap (Thermofisher, Sweden). Results. Identified 5 species of Malassezia, absolutely dominated M. sympodialis. IgE-antibodies to Malassezia spp. were detected in 45% (42/93) of patients with atopic dermatitis: 11% - children with ADL, 22% from the ADB and 67% from the ADT. Statistically significant correlation between the level of IgE-antibodies to the yeast Malassezia spp. and severity of atopic dermatitis (SCORAD) - r=0,5928, p&lt;0,05 was revealed. The frequency of detection and concentration of IgE-antibodies to Malassezia spp. is increasing with the age of the children. Positive values of IgE-antibodies to Malassezia spp. were identified only in children with presentability. In 7 out of 24 children (29%) with positive IgE values-aT to Malassezia spp. were identified IgE-antibodies to the major fungal allergen - superoxide dismutase Mn (Mn-SOD). Conclusion. Thus, neither species diversity nor the number of yeasts of the genus Malassezia spp. do not affect the severity of atopic dermatitis. The clinical significance of IgE-antibodies to Malassezia spp. and IgE-antibodies to Mn-SOD was shown.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Изучить видовое разнообразие и количественное соотношение липофильных дрожжей рода Malassezia на коже детей с атопическим дерматитом (АтД) и в группах контроля, оценить возрастные особенности и клиническое значение сенсибилизации к Malassezia и присутствия IgE к мажорному аллергену данного гриба (марганец-зависимой супероксиддисмутазе - Mn-SOD - у детей с АтД. Материалы и методы. В исследовании приняли участие 144 ребенка в возрасте от 1 года до 14 лет: 93 пациента с АтД, группы контроля: К1 - 24 ребенка с бронхиальной астмой и/или аллергическим ринитом без АтД и К2 - 27 здоровых детей без заболеваний кожи. Дрожжи Malassezia spp. идентифицировали по морфологическим и физиологическим признакам и с помощью анализа нуклеотидных последовательностей D1/D2 региона 26S (LSU) рДНК. Для выявления аллерген-специфических IgE к различным аллергенам, включая Malassezia, использовали прибор и реагенты ImmunoCap (Thermofisher, Sweden); IgE к Mn-SOD выявляли методом ISAC ImmunoCap (Thermofisher, Sweden). Результаты. Выявлено 5 видов Malassezia, абсолютно доминировал M. sympodialis. IgE к Malassezia spp. выявлены у 45% (42/93) пациентов с АтД: 11% - дети с легким течением, 22% - со среднетяжелым и 67% - с тяжелым течением. Выявлена статистически достоверная корреляция между уровнем IgE к дрожжам Malassezia spp. и тяжестью течения АтД (SCORAD) - r=0,5928, p&lt;0,05. Частота выявления и концентрация IgE к Malassezia spp. нарастают с возрастом детей. Положительные значения IgE к Malassezia spp. выявляли только у детей с полисенсибилизацией. У 7 из 24 детей (29%) с положительными значениями IgE к Malassezia spp. были выявлены IgE к мажорному аллергену гриба - Mn-SOD. Заключение. Таким образом, ни видовое разнообразие, ни численность дрожжей рода Malassezia spp. не влияют на тяжесть течения АтД. Клиническое значение имеют IgE к Malassezia spp. и IgE к Mn-SOD.</p></trans-abstract><kwd-group xml:lang="en"><kwd>IgE-antibodies</kwd><kwd>Malassezia</kwd><kwd>atopic dermatitis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>атопический дерматит</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ashbee H.R.
