Их клиническое течение отличается выраженной гетерогенностью. Степень клинических проявлений зависит не только от электрофизиологических свойств субстрата аритмии, но и от индивидуальной реактивности симпатической нервной системы (СНС). Несмотря на понимание общей роли СНС, оценка ее индивидуального вклада у конкретного пациента остается сложной задачей. Бета-адренореактивность мембран эритроцитов (β-АРМ) является интегральным маркером функционального состояния β-адренорецепторов и оценивает их функциональное состояние in vitro по степени стабилизации мембраны под действием β-адреноблокатора. Повышение показателя β-АРМ (&gt; 20 усл. ед.) интерпретируется как признак десенситизации рецепторов – адаптационного ответа на их хроническую гиперстимуляцию, что служит косвенным маркером длительной симпатической гиперактивации.</p><sec><title>Цель</title><p>Цель: оценить уровень β-АРМ у детей с различными формами ПСРТ и определить его взаимосвязь с наличием, частотой и тяжестью клинических пароксизмов.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В одноцентровое ретроспективное исследование включены 38 детей в возрасте от 7 до 17 лет, из них 15 (группа 1) – с асимптомным феноменом Вольфа – Паркинсона – Уайта (WPW) и 23 (группа 2) – с симптомными ПСРТ (с синдромом WPW и атриовентрикулярной узловой реципрокной тахикардией (АВУРТ)). Уровень β-АРМ определяли фотометрическим методом по торможению гипотонического гемолиза неселективным β-блокатором in vitro. Клиническую тяжесть оценивали по оригинальной балльной шкале.</p></sec><sec><title>Результаты</title><p>Результаты. Уровень β-адренореактивности мембран эритроцитов (β-АРМ) был статистически значимо выше у детей с симптомными суправентрикулярными реентри тахикардиями по сравнению с бессимптомным феноменом WPW (21,5 ± 8,9 усл. ед. vs 14,2 ± 3,5 усл. ед.; p = 0,01). Каждое увеличение β-АРМ на 1% повышало шансы симптомного течения в 2,05 раза (OR = 2,05; 95% ДИ: 1,28–3,28; p = 0,003). Более высокие значения β-АРМ выявлены у пациентов с пароксизмами в покое (22,5 [20,8; 24,2] усл. ед.) по сравнению с нагрузочными (18,9 [16,1; 21,7] усл. ед.; p = 0,032), а также у пациентов, требующих медикаментозного купирования (20,51 [17,70; 37,47] усл. ед.) по сравнению со спонтанно купирующимися (16,20 [10,44; 20,00] усл. ед.; p = 0,041). Наиболее тяжелое течение, характеризующееся частыми, резистентными к купированию, длительными пароксизмами с высокой частотой сердечных сокращений (ЧСС), возникало при высоких уровнях β-АРМ (32,6 [24,12; 38,62] усл. ед.).</p></sec><sec><title>Заключение</title><p>Заключение. Повышенный уровень β-АРМ, отражающий десенситизацию β-адренорецепторов, является статистически значимым предиктором симптомного течения ПСРТ у детей и возникает в группе с более тяжелым клиническим фенотипом. Определение β-АРМ может служить дополнительным неинвазивным инструментом для стратификации риска у детей с бессимптомным феноменом WPW.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Paroxysmal supraventricular reentrant tachycardias (PSRTs) are the most common class of tachyarrhythmias in childhood. Their clinical course is characterized by marked heterogeneity. The severity of clinical manifestations depends not only on the electrophysiological properties of the arrhythmia substrate but also on the individual reactivity of the sympathetic nervous system (SNS). Despite understanding the general role of the SNS, assessing its individual contribution in a particular patient remains challenging. Beta-adrenergic reactivity of erythrocyte membranes (β-ARM) is an integral marker of β-adrenergic receptor function and assesses their functional state in vitro based on the degree of membrane stabilization under the influence of a β-blocker. An increase in β-ARM (&gt; 20 arbitrary units) is interpreted as a sign of receptor desensitization–an adaptive response to chronic hyperstimulation, which serves as an indirect marker of prolonged sympathetic hyperactivation.</p></sec><sec><title>Aim</title><p>Aim: To assess β-ARM levels in children with various forms of WPW and determine their relationship with the presence, frequency, and severity of clinical paroxysms.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. A single-center retrospective study included 38 children aged 7 to 17 years, including 15 (Group 1) with asymptomatic WPW syndrome and 23 (Group 2) with symptomatic WPW syndrome (WPW syndrome and AVNRT). β-ARM levels were determined photometrically by in vitro inhibition of hypotonic hemolysis with a nonselective β-blocker. Clinical severity was assessed using an original scoring system. Statistical analysis included the Mann – Whitney U test, Spearman correlation, and logistic regression.</p></sec><sec><title>Results</title><p>Results. The level of β-adrenergic activity of erythrocyte membranes (β-ARM) was significantly higher in children with symptomatic supraventricular reentrant tachycardias compared to asymptomatic WPW phenomenon (21.5 ± 8.9 arbitrary units vs 14.2 ± 3.5 arbitrary units; p = 0.01). Each 1% increase in β-ARM increased the odds of a symptomatic course by 2.05 times (OR = 2.05; 95% CI: 1.28–3.28; p = 0.003). Higher values of β-ARM were found in patients with paroxysms at rest (22.5 [20.8; 24.2] arbitrary units) compared to those with exercise (18.9 [16.1; 21.7] arbitrary units; p = 0.032), as well as in patients requiring drug relief (20.51 [17.70; 37.47] arbitrary units) compared to those spontaneously relieved (16.20 [10.44; 20.00] arbitrary units; p = 0.041). The most severe course, characterized by frequent, treatment-resistant, prolonged paroxysms with a high heart rate, is associated with the highest β-ARM level (32.6 [24.12; 38.62] arbitrary units; p = 0.009).</p></sec><sec><title>Conclusion</title><p>Conclusion. Elevated β-ARM levels, reflecting β-adrenergic receptor desensitization, are a statistically significant predictor of symptomatic PSRT course in children and are associated with a more severe clinical phenotype. Determination of β-ARM can serve as an additional non-invasive tool for risk stratification in children with asymptomatic WPW.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>детская кардиология</kwd><kwd>суправентрикулярная тахикардия</kwd><kwd>вегетативная нервная система</kwd><kwd>бета-адренорецепторы</kwd><kwd>адренореактивность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pediatric cardiology</kwd><kwd>supraventricular tachycardia</kwd><kwd>autonomic nervous system</kwd><kwd>beta-adrenergic receptors</kwd><kwd>adrenergic reactivity</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>исследование выполнено в рамках государственного задания Министерства науки и высшего образования Российской Федерации, № гос. регистрации 122020300183-4</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>the study was conducted within the framework of the state assignment of the Ministry of Science and Higher Education of the Russian Federation, state registration number 122020300183-4</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Obeyesekere M.N., Leong-Sit P., Massel D., Manlucu J., Modi S., Krahn A.D., et al.
