Изучить влияние долгосрочного хранения при -70О  С и однократного размораживания образцов сыворотки крови, хранящихся в биобанке ФГБУ “НМИЦ ТПМ” Минздрава России (Биобанк), на биохимические показатели сыворотки крови, характеризующие функционирование ряда метаболических систем, путем сравнения результатов исследований, проведенных в 20132014 и 2020гг.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Материалом для исследования служила сыворотка крови участников многоцентрового эпидемиологического исследования ЭССЕ-РФ, хранившаяся в специализированном Биобанке с 2013-2014гг при -70О С либо непрерывно (n=149), либо с однократным размораживанием (n=20). Количественное определение биохимических показателей сыворотки крови исходно и в 2020г выполнено на одном и том же оборудовании и с использованием одних и тех же стандартных методов.</p></sec><sec><title>Результаты</title><p>Результаты. Длительное хранение при -70О С привело к небольшим, но статистически значимым изменениям практически всех анализируемых показателей: снизились уровни холестерина (ХС) липопротеинов низкой плотности (ЛНП), аполипопротеина АI, возрос уровень ХС липопротеинов высокой плотности, триглицеридов и аполипопротеина В, а также глюкозы, и высокочувствительного С-реактивного белка. Уровни инсулина и тиреотропного гормона за время хранения не изменились. В то же время, выявленные сильные положительные связи между исходными уровнями показателей и измеренными в 2020г в образцах, хранившихся непрерывно, свидетельствуют о правомочности такого хранения. В однократно размороженных за время хранения образцах изменения большинства показателей были более выраженными.</p></sec><sec><title>Заключение</title><p>Заключение. Результаты проспективного когортного исследования, направленного на изучение стабильности образцов сыворотки крови человека во время их хранения в Биобанке, свидетельствуют о правомочности длительного хранения биообразцов при -70О С без размораживания. Размораживание и повторное замораживание образцов во время хранения (даже однократное) недопустимо, поскольку приводит к выраженному снижению уровня ХС ЛНП. Учитывая тот факт, что именно уровень ХС ЛНП является мишенью липид-снижающей терапии, рекомендуется непрерывное низкотемпературное (не &gt;-70О С) хранение образцов сыворотки крови, предназначенных для анализа этого показателя.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To study the effect of standard serum long-term storage at -70О C and with a single thawing on the biochemical markers by comparing the results of studies carried out in 2013-2014 and 2020.</p></sec><sec><title>Material and methods</title><p>Material and methods. The material was the blood serum of participants in the ESSE-RF study, which was stored in a specialized biobank from 2013-2014 at -70О C either continuously (n=149) or with a single thawing (n=20). Initially and in 2020, the quantitative determination of serum biochemical parameters was carried out using same equipment and standard techniques.</p></sec><sec><title>Results</title><p>Results. Long-term storage at -70О C led to mild, but significant changes in almost all analyzed parameters: low density lipoprotein cholesterol (LDL-C) and apolipoprotein A1 levels decreased; levels of highdensity lipoprotein cholesterol (HDL-C), triglycerides, apolipoprotein B, glucose, and high-sensitivity C-reactive protein increased. Insulin and thyroid-stimulating hormone levels did not change during storage. The revealed strong positive relationships between the initial concentrations and those measured in 2020 in samples that were stored continuously indicate the relevance of such storage. In samples with single thawing, changes in most parameters were more pronounced.</p></sec><sec><title>Conclusion</title><p>Conclusion. The results of a prospective cohort study aimed at studying the stability of human serum samples during storage indicate the validity of long-term storage at -70О C without thawing. Freeze-thawing cycle of samples (even once) is unacceptable, since it leads to a pronounced LDL-C decrease. Given the fact that it is the LDL-C levels that is the target of lipid-lowering therapy, continuous low-temperature (not &gt;-70О C) storage of blood serum samples is recommended.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>биобанкирование</kwd><kwd>длительное хранение</kwd><kwd>замораживание/оттаивание</kwd><kwd>стабильность</kwd><kwd>контроль качества</kwd><kwd>биообразцы</kwd><kwd>сыворотка крови</kwd><kwd>биохимические маркеры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>biobanking</kwd><kwd>long-term storage</kwd><kwd>freeze-thawing</kwd><kwd>stability</kwd><kwd>quality control</kwd><kwd>biosamples</kwd><kwd>blood serum</kwd><kwd>biochemical markers.</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">Ellervik C, Vaught J.
