Без своевременной ранней диагностики и лечения дети с ПИД страдают от инфекционных заболеваний с тяжелым течением, что приводит к их инвалидизации или смерти.</p><p>Цель: разработать и апробировать на группе детей с верифицированными диагнозами ТКИН и Х-сцепленной агаммаглобулинемией простую, недорогую, высокопропускную методику на основе количественного определения молекул ДНК TREC и KREC с помощью ПЦР в режиме реального времени.</p><p>В настоящем исследовании мы разработали и валидировали метод проведения мультиплексной полимеразной цепной реакции в режиме «реального времени» для количественного анализа молекул ДНК TREC и KREC. Нами было показано, что в области концентраций от 109 коп/мл до 5 × 104 коп/мл для всех мишеней наблюдается линейный диапазон изменения Сt в зависимости от концентрации с коэффициентом корреляции R2 не хуже 0,98. Наименьшее количество копий, надежно детектиру емых в одной ПЦР реакции объемом 25 мкл, было: 10 для TREC, 5 для KREC и 5 для внутреннего контроля – локуса IL17RA. Нами определены референсные значения для количества TREC и KREC в цельной крови в зависимости от возраста в группе из 29 мальчиков и 27 девочек с нормальными иммунологическими параметрами. Были определены граничные значения для содержания TREC и KREC в сухих пятнах крови в зависимости от метода экстракции ДНК.</p><p>Предложенная методика показала 100% диагностическую чувствительность и специфичность на исследуемой выборке. Метод может быть предложен как скрининговый для диагностики ТКИН и Х-сцепленной агаммаглобулинемии как в цельной крови, так и в сухих пятнах крови. Требуется дальнейшая апробация методики на выборках большего объема. </p></abstract><trans-abstract xml:lang="en"><p>Primary immunodeficiencies (PID) such as severe combined immunodeficiency (SCID) and X-linked agammaglobulinemia are characterized by the lack of functional Tand B-cells, respectively. Without early diagnosis and prompt treatment children with PID suffer from severe infectious diseases, leading to their death or disability. Our purpose was developing of simple, inexpensive, high throughput technique based on the quantitative determination of TREC and KREC molecules by real-time PCR, and its validation in a group of children with a verified diagnosis of SCID and X-linked agammaglobulinemia.</p><p>In this study, we developed and validated multiplex real-time PCR for the TREC’s and KREC’s quantitative analysis. We have shown that linear range of Ct changes depending on the concentrations of targets with a correlation coefficient R2 not worse than 0.98 was observed at concentrations from 109 to 5 × 104 copies per ml. The lowest amount of targets reliably detected in a reaction volume was 10 TREC’s copies, 5 KREC ‘s copies and 5 copies of internal control (IL17RA). We determined the age-depended reference values of TRECs and KRECs in whole blood in 29 boys and 27 girls with normal immunological parameters. The normal cut-offs for TRECs and KRECs were defined in dry blood spots depending on the method of extraction.</p><p>The proposed method showed 100% diagnostic sensitivity and specificity in the studied group. The method can be proposed as a screening tool for the diagnosis of SCID and X-linked agammaglobulinemia both in whole blood and in the dry blood spots. The further investigation is required with larger number of samples. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>первичный иммунодефицит</kwd><kwd>диагностика</kwd><kwd>TREC</kwd><kwd>KREC</kwd><kwd>количественная ПЦР</kwd></kwd-group><kwd-group xml:lang="en"><kwd>primary immunodeficiency</kwd><kwd>diagnostics</kwd><kwd>TREC</kwd><kwd>KREC</kwd><kwd>real-time PCR</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">Alt F.W., Oltz E.M., Young F., Gorman J., Taccioli G., Chen J.
