A prospective cohort study was conducted. Serum and plasma samples were retrieved dynamically from a biocollection during the first and second trimesters of gestation from 18 pregnant women with PB high risk developed cervical insufficiency (CI), and from 18 pregnant women with PB low risk not complicated by СI at any stage of gestation. Clinical and anamnestic predictors were analyzed, and serum relaxin and elastin levels, as well as marker microRNAs (hsa-miR-432-5p, hsa-miR-134-5p, hsa-miR-431-5p, hsa-miR-122-5, and hsa-miR-34a-5p) were quantitated.</p></sec><sec><title>Results</title><p>Results. Based on the most significant clinical and anamnestic predictors, a proteomic predictor (serum relaxin level), and transcriptomic predictors (marker microRNAs expression) using a support vector machine (SVM), a predictive model was developed, which high efficiency was confirmed by ROC curves (AUC = 0.83 during training and 0.67 in cross-validation). This allows the developed classifier to be used as a tool for assessing PB risk.</p></sec><sec><title>Conclusion</title><p>Conclusion. Biocollections of pregnant women's samples, formed according to the "longitudinal biobanking" strategy, can serve as an effective platform for developing technologies for early predicted PB risk of obstetric complications.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель: на платформе биоколлекции образцов беременных, созданной согласно стратегии «лонгитюдное биобанкирование», разработать алгоритм раннего моделирования высокого риска преждевременных родов (ПР) на основе клинических, протеомных и транскриптомных данных.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено проспективное когортное исследование. Из биоколлекции были отобраны образцы сыворотки и плазмы крови, полученные в динамике в I и II триместрах гестации от 18 беременных с высоким риском ПР, реализовавших истмико-цервикальную недостаточность (ИЦН), и от 18 женщин с низким риском ПР, беременность которых не была осложнена ИЦН на любом сроке гестации. Проведен анализ клинико-анамнестических предикторов, определен уровень сывороточного релаксина и эластина, маркерных микроРНК (hsa-miR-432-5p, hsa-miR-134-5p, hsa-miR-431-5p, hsa-miR-122-5, hsa-miR-34a-5p).</p></sec><sec><title>Результаты</title><p>Результаты. На основе наиболее значимых клинико-анамнестических предикторов, протеомного предиктора (уровень сывороточного релаксина), транскриптомных предикторов (экспрессия маркерных микроРНК) с использованием метода опорных векторов (англ. support vector machine, SVM) разработана прогностическая модель, высокая эффективность которой подтверждается ROC-кривыми (AUC = 0,83 при обучении и 0,67 в кросс-валидации), что позволяет использовать разработанный классификатор в качестве инструмента для оценки риска ПР.</p></sec><sec><title>Заключение</title><p>Заключение.
