Исследования выполнены в модельном эксперименте путем фракционирования в лабораторных условиях нормального пула донорской плазмы, контаминированного вируссодержащими образцами. Установлено, что многостадийный процесс выделения фракции II, предназначенной для получения иммуноглобулина G, обеспечивал элиминацию НК ВГВ и ВГС до неопределяемого методом ПЦР уровня, при этом суммарный фактор редукции по сравнению с исходной плазмой составил для ДНК ВГВ &gt;5,35 lg, РНК ВГС &gt;4,84 lg. Фактор редукции ДНК B19V был на уровне 4,56 lg (CI 4,49-4,63). При получении фракции V (для альбумина) фактор редукции исследуемых вирусов был &gt;3,0 lg, что в совокупности с дополнительными стадиями очистки обеспечивает надежный уровень безопасности. При выделении фракции I эффективность элиминации ДНК ВГВ и ДНК B19V была менее 2, РНК ВГС - менее 3 порядков, что недостаточно, чтобы признать стадию надежной. Экспериментально подтверждено, что при высоком риске контаминации производственных пулов парвовирусом B19 дополнительные меры безопасности необходимы, включая обязательное исследование плазмы на ДНК B19V. В целом, при разработке полного цикла производства препаратов из плазмы крови доноров базовый процесс спиртового фракционирования необходимо дополнять валидированными стадиями инактивации и элиминации вирусов с учетом остаточного риска контаминации сырья патогенными агентами.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of the study was to assess the effectiveness of the removal of nucleic acids (NA), Hepatitis B (HBV) and C (HCV) viruses and parvovirus B19 (B19V) from blood plasma fractions obtained by alcohol separation. The studies were performed in a model experiment by fractionation normal pool plasma donation contaminated with virus-containing samples in the laboratory. It was found that the multi-step process to extract a fraction II, designed to provide the immunoglobulin G, provided the elimination of NA HBV and HCV to undetectable levels by PCR, and the total reduction factor compared to the original composition of the plasma HBV DNA &gt;5.35 log, HCV RNA &gt;4.84 log. Factor DNA V19V reduction was at the level of 4.56 log(CI 4.49-4.63). Upon receipt of the fraction V (for albumin) reduction factor of the test virus was &gt;3.0 log wich in combination with additional purification step provides a reliable level of safety. The selection fraction I resulted in effectiveness of the elimination of HBV DNA and V19V DNA less than 2 orders, HCV RNA - less than 3 orders of magnitude, it is not enough to recognize the stage reliable. Experiments confirmed that the high risk of contamination of production pools parvovirus B19 additional safety measures are necessary, including mandatory investigation of plasma DNA V19V. In general the development of a full cycle of drug from blood plasma from donors, basic process alcohol fractionation steps necessary to supplement validation virus elimination and inactivation considering residual risk of contamination with pathogenic agents feedstock.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>препараты из плазмы крови</kwd><kwd>фракции плазмы</kwd><kwd>вирусная безопасность</kwd><kwd>спиртовое фракционирование</kwd><kwd>инактивация вирусов</kwd><kwd>нуклеиновые кислоты</kwd><kwd>концентрация вирусов (С)</kwd><kwd>вирусная нагрузка (VL)</kwd><kwd>фактор редукции (RF)</kwd><kwd>drugs from blood plasma</kwd><kwd>plasma fractions</kwd><kwd>viral safety</kwd><kwd>alcohol fractionation</kwd><kwd>viral inactivation</kwd><kwd>nucleic acids</kwd><kwd>virus concentration (С)</kwd><kwd>viral load (VL)</kwd><kwd>the reduction factor (RF)</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">Burnouf T.
