Одной из наиболее значимых и распространенных причин ложного повышения уровней сердечных тропонинов являются гетерофильные антитела. В отечественных и зарубежных базах данных отсутствуют статьи, которые подробно систематизируют информацию о распространенности, механизмах повышения и способах борьбы с данной причиной ложнополотельного повышения концентрация сердечных тропонинов, что и стало целью данной рукописи.</p></sec><sec><title> </title><p> </p></sec><sec><title>Аннотация</title><p>Аннотация</p><p>Согласно традиционным представлениям, кардиоспецифические тропонины (cTnT и cTnI) являются наиболее важными лабораторными биомаркерами, обладающими высокой диагностической ценностью при инфаркте миокарда. Появление высоко- и ультрачувствительных систем определения cTnT и cTnI расширило диагностические возможности в отношении других заболеваний, при которых в патологический процесс вовлекается ткань миокарда, что тем самым представляет дополнительную прогностическую ценность. Учитывая столь важное значение и широкие возможности для использования cTnT и cTnI, которые не ограничивается только диагностикой инфаркта миокарда, существует острая необходимость тщательного установления всех факторов, способных каким-либо образом повлиять или исказить результат лабораторного исследования сыворотки крови. Среди известных факторов, влияющих на повышение cTnT и cTnI в сыворотке крови, наибольшую роль играют гетерофильные антитела. В настоящем обзоре подробно рассмотрены основные причины образования гетерофильных антител, механизмы их влияния на концентрацию cTnT и cTnI, а также способы выявления и борьбы с гетерофильными антителами.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Highlights</title><p>Highlights</p><p>Practitioners regularly encounter unexplained (false-positive) causes and mechanisms of increased concentrations of cardiac troponins. One of the most significant and common causes of false increases in cardiac troponin levels are heterophile antibodies. There are no articles in domestic and foreign databases that systematize in detail information about the prevalence, mechanisms of increase and ways to combat this cause of false-positive increase in cardiac troponin concentration, which was the purpose of this manuscript.</p></sec><sec><title> </title><p> </p></sec><sec><title>Annotation</title><p>Annotation</p><p>According to traditional concepts, cardiospecific troponins (cTnT and cTnI) are the most important laboratory biomarkers with high diagnostic value in myocardial infarction (MI). The development of new generations of methods for determining cTnT and cTnI, also called high- and ultra-sensitive methods, has expanded the diagnostic capabilities of cardiac troponins in relation to other diseases in which myocardial tissue is involved in the pathological process, thereby carrying additional prognostic value. Given the wide scope for use of cTnT and cTnI, which is not limited to the diagnosis of MI, there is an urgent need to carefully identify all factors that can in any significant way affect or distort the result of laboratory testing of blood serum for cTnT and cTnI. Among all known factors affecting the concentration of cTnT and cTnI, heterophile antibodies are the most significant in terms of the degree of change (increase) in serum levels. In this review, we will consider the main causes of the formation of heterophile antibodies, the mechanisms of their influence on the concentration of cTnT and cTnI, as well as methods for detecting and combating heterophile antibodies.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Гетерофильные антитела</kwd><kwd>Сердечные тропонины</kwd><kwd>Ложноположительные результаты</kwd><kwd>Сердечно-сосудистые заболевания</kwd><kwd>Инфаркт миокарда</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Heterophile antibodies</kwd><kwd>Cardiac troponins</kwd><kwd>False-positive result</kwd><kwd>Cardiovascular diseases</kwd><kwd>Myocardial infarction</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Авторы заявляют об отсутствии финансирования исследования.</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">Thygesen K., Alpert J.S., Jaffe A.S., Chaitman B.R., Bax J.J., Morrow D.A., White H.D.; ESC Scientific Document Group.Fourth universal definition of myocardial infarction (2018).
