Рост числа случаев инфекций, в том числе инвазивных форм, вызванных бета-гемолитическим стрептококком группы А, подчеркивает важность рутинной этиологической диагностики на ранних этапах, что позволяет своевременно и обоснованно начать лечение антибактериальными препаратами и избежать возможных осложнений.</p><p>Иммунохроматографические экспресс-тесты, обладая высокими показателями чувствительности и специфичности (95–97%), способствуют быстрому и качественному выявлению антигена бета-гемолитического стрептококка группы А в мазке из ротоглотки.</p><sec><title>Цель</title><p>Цель: валидация экспресс-тест-системы для выявления бета-гемолитического стрептококка группы А (Streptococcus pyogenes) в мазках из ротоглотки у пациентов с подозрением на стрептококковый тонзиллофарингит методом иммунохроматографического анализа «РАПИД-Стрептококк-А-ИХА» с определением ее диагностических характеристик (чувствительность, специфичность, перекрестная реактивность с Streptococcus agalactiae).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы: исследование проводилось на биообразцах – мазках из ротоглотки, полученных от пациентов с клиническими признаками бактериального острого тонзиллофарингита. Было апробировано 34 экспресс-тест-систем для выявления бета-гемолитического стрептококка группы А «РАПИД-Стрептококк-А-ИХА» на 28 образцах с разными значениями колониеобразующих единиц бетагемолитического стрептококка группы А и 6 образцах сравнения. Исследование проводилось в 2 этапа. На первом этапе проводилось формирование выборки образцов согласно плану исследования и определение значения КОЕ в образцах. На втором этапе выполнялось тестирование биообразцов с использованием апробируемых экспресс-тестов и регистрировались полученные результаты.</p></sec><sec><title>Результаты</title><p>Результаты: по результатам проведенных испытаний набор реагентов «РАПИД-Стрептококк-А-ИХА» показал высокие показатели диагностической чувствительности (93–100%) и специфичности (100%), сопоставимые с показателями ведущих международных аналогов.</p></sec><sec><title>Заключение</title><p>Заключение: проведение экспресс-тестирования как вспомогательного метода выявления бетагемолитического стрептококка группы А способно существенно оптимизировать диагностический алгоритм при острых тонзиллофарингитах, обеспечивая своевременную этиотропную терапию инфекции и снизить частоту необоснованной антибиотикотерапии.</p></sec></abstract><trans-abstract xml:lang="en"><p>Group A streptococcus (GAS) is the leading bacterial cause of acute tonsillopharyngitis, as well as infections in other locations, most commonly skin infections, phlegmon, and erysipelas. It is important to start early specific antibacterial therapy in a timely manner especially to prevent possible complications.</p><p>Rapid antigen tests have high sensitivity and specificity (95-97%), facilitate the rapid and accurate detection of GAS antigen in throat swabs.</p><sec><title>Objective</title><p>Objective: validation of the rapid test “RAPID-Streptococcus-A-LF” for detecting GAS (Streptococcus pyogenes) antigen in throat swabs from patients with suspected Streptococcal tonsillopharyngitis using the RAPID-StreptococcusALF immunochromatographic assay and to determine its diagnostic characteristics (sensitivity, specificity, and crossreactivity with Streptococcus agalactiae).</p></sec><sec><title>Materials and Methods</title><p>Materials and Methods: sample type – throat swabs from patients with acute tonsillopharyngitis. 34 rapid antigen tests “RAPID-Streptococcus-A-LF” were tested on 28 samples with different colony-forming unit (CFU) counts of GAS and 6 comparison samples. The study was performed in two phases: the first phase involved sample selection according to the study plan and determination of CFU values in the samples, while the second phase included testing biological samples on the antigen tests and recording the results.</p></sec><sec><title>Results</title><p>Results: the “RAPID-Streptococcus-A-LF” antigen test showed high diagnostic sensitivity (93-100%) and specificity (100%) similar to the leading imported tests on Russian market.</p></sec><sec><title>Conclusion</title><p>Conclusion: rapid testing, as an auxiliary method for detecting GAS, can significantly optimize the diagnostic algorithm for acute tonsillopharyngitis, ensuring timely etiotropic treatment of GAS infection and reducing the incidence of unnecessary antibiotic therapy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>бета-гемолитический стрептококк группы А</kwd><kwd>Streptococcus pyogenes</kwd><kwd>острый тонзиллофарингит</kwd><kwd>экспресс-тест</kwd><kwd>иммунохроматографический анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>group A beta-hemolytic streptococcus</kwd><kwd>Streptococcus pyogenes</kwd><kwd>acute tonsillopharyngitis</kwd><kwd>rapid antigen test</kwd><kwd>immunochromatographic analysis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Карпищенко С.А., Рябова М.А., Колесникова О.М., Улупов М.Ю.
