В статье анализируется эффективность биомаркеров в диагностике митохондриальной дисфункции.</p><sec><title>Цель исследования</title><p>Цель исследования. Усовершенствование диагностической панели биомаркеров при митохондриальных нарушениях у детей на основе ряда потенциальных лабораторных показателей, таких как FGF-21и GDF-15 лактат, пируват, креатинин, ацилкарнитины.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проанализированы данные 82 пациента в возрасте от 1 до 17 лет. Измеряли уровни указанных биомаркеров у пациентов с подозрением на митохондриальные заболевания. Для каждого биомаркера рассчитаны чувствительность и специфичность, площадь под характеристической кривой (AUC).</p></sec><sec><title>Результаты</title><p>Результаты. Для FGF-21 площадь AUC составила 0,862±0,091, чувствительность — 80% у пациентов с митохондриальными нарушениями, специфичность — от 88 до 100%. GDF-15 продемонстрировал наибольшую AUC среди изученных биомаркеров (0,898±0,103), чувствительность — 92%, специфичность — от 91 до 100%, что указывало на его особенно высокую прогностическую эффективность. Исследование лактата выявило, что при повышении его уровня у пациентов с митохондриальными нарушениями в 37 случаях из 52 чувствительность составила 75%, специфичность — от 85 до 100%, средняя — AUC 0,861±0,049, а при повышенном уровне креатинина чувствительность была ниже и составила 35,7% (19 из 52 детей с митохондриальными нарушениями). Для пирувата AUC составила 0,835±0,106, подтверждая его информативность как дополнительного биомаркера вместе с лактатом.</p></sec><sec><title>Заключение</title><p>Заключение. Исследования показали, что новые показатели FGF-21 и GDF-15 особенно выделяются своей диагностической ценностью и могут быть рекомендованы для широкого применения в медицинской практике.</p></sec></abstract><trans-abstract xml:lang="en"><p>It is known that biopsy and DNA sequencing methods are used to diagnose mitochondrial diseases, but such diagnostic options are not available for all tissues, especially for the central nervous system.

Eighty-two patients aged 1 to 17 years were analyzed. The levels of these biomarkers were measured in patients with suspected mitochondrial diseases.

FGF-21 showed an AUC of 0.862 ± 0.091 and a sensitivity of 80% in patients with mitochondrial disorders, with specificity ranging from 88 to 100%. GDF-15 demonstrated the highest AUC among the studied biomarkers (0.898 ± 0.103), a sensitivity of 0.92, and a specificity of 91 to 100%, indicating its particularly high efficacy. The study of lactate revealed that with its increased level, there is a sensitivity of 75% in patients with mitochondrial disorders (MD), which was confirmed in 37 cases out of 52, and a specificity from 85 to 100%, the average AUC was 0.861 ± 0.049, and for creatinine with an increased level, the sensitivity was lower and was 35.7% (19 out of 52 children with MD. For pyruvate, AUC was 0.835 ± 0.106, confirming its usefulness as an additional biomarker together with lactate.</p></sec><sec><title>Conclusion</title><p>Conclusion.
