Оценка содержания пирогенных примесей в вакцине брюшнотифозной Ви-полисахаридной (Вианвак®) проводится в настоящее время только биологическим тестом на пирогенность. Определение бактериальных эндотоксинов (БЭ) с помощью гель-тромб теста и введение показателя «Бактериальные эндотоксины» в нормативную документацию на препарат позволят существенно повысить надежность контроля качества данной вакцины, а также гармонизировать требования к ней с требованиями ведущих фармакопей мира к данной группе лекарственных препаратов.</p></sec><sec><title>Цель</title><p>Цель. Экспериментальная оценка возможности определения содержания бактериальных эндотоксинов с помощью гель-тромб теста в брюшнотифозной Ви-полисахаридной вакцине.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Образцы вакцины брюшнотифозной Ви-полисахаридной (раствор для подкожного введения, 0,5 мл/доза) пяти серий; ЛАЛ-реактив; ТАЛ-реактив. Испытания проводились с использованием гель-тромб теста с учетом требований Государственной фармакопеи Российской Федерации (ОФС.1.2.4.0006.15) и теста на пирогенность согласно ОФС.1.2.4.0005.15.</p></sec><sec><title>Результаты</title><p>Результаты. Расчетное предельное содержание БЭ в испытуемой вакцине составляет 96 ЕЭ/мл, значение максимально допустимого разведения (МДР) — 3200. Установлены нормативные требования к качеству вакцины по показателю «Бактериальные эндотоксины» (не более 48 ЕЭ/доза). Выявлено наличие БЭ в разведениях препарата 1/16–1/32 и отсутствие — в разведениях 1/64–1/256. Выбрано и валидировано рабочее разведение препарата 1/128. Полученные значения содержания БЭ в исследуемых образцах находятся в диапазоне от 0,24 до 0,48 ЕЭ/доза. Испытания на пирогенность in vivo образцов пяти серий вакцины в разведениях от 1/16 до 1/256 показали, что введение животным препарата в разведениях 1/16–1/128 вызывало пирогенную реакцию, а при введении вакцины в разведении 1/256 пирогенная реакция отсутствовала во всех экспериментах.</p></sec><sec><title>Выводы</title><p>Выводы. Экспериментально доказана возможность определения бактериальных эндотоксинов в вакцине брюшнотифозной Ви-полисахаридной с помощью гель-тромб теста. Рекомендовано введение показателя «Бактериальные эндотоксины» в Государственную фармакопею Российской Федерации ФС.3.3.1.0012.15 «Вакцина брюшнотифозная Ви-полисахаридная».</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Scientific relevance</title><p>Scientific relevance. Currently, only the rabbit pyrogen test is used to test the Vianvac® typhoid Vi polysaccharide vaccine for pyrogenicity. As part of the product specification file, the gel-clot test for bacterial endotoxins (BE) will improve the reliability of quality control, as well as harmonise the requirements for the vaccine with the requirements outlined for this group of medicinal products by leading world pharmacopoeias.</p></sec><sec><title>Aim</title><p>Aim. This study aimed at an experimental assessment of the applicability of the gel-clot test to the quantification of BE in the typhoid Vi polysaccharide vaccine.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. This study used samples from 5 batches of the typhoid Vi polysaccharide vaccine (0.5 mL/dose, solution for subcutaneous injection), LAL and TAL reagents. The analysis included the gel-clot test and the pyrogenicity test according to the State Pharmacopoeia of the Russian Federation (OFS.1.2.4.0006.15 and OFS.1.2.4.0005.15, respectively).</p></sec><sec><title>Results</title><p>Results. According to calculations, the BE limit for the tested vaccine was 96 EU/mL, and the maximum valid dilution (MVD) was 3200. The authors determined the regulatory requirements for typhoid Vi polysaccharide vaccine quality in terms of BE (not more than 48 EU/dose). The in vitro BE tests were positive at vaccine dilutions of 1/16 to 1/32 and negative at 1/64 to 1/256. The authors selected and validated a working vaccine dilution of 1/128. The BE content measured in the tested samples ranged from 0.24 to 0.48 EU/dose. The in vivo pyrogen tests were positive at dilutions of 1/16 to 1/128 and negative at 1/256 in all experiments with samples from 5 vaccine batches at dilutions ranging from 1/16 to 1/256.</p></sec><sec><title>Conclusions</title><p>Conclusions. This study has experimentally proven that the gel-clot test can quantify BE in the typhoid Vi polysaccharide vaccine. The authors have recommended introducing the gel-clot BE test in the monograph of the State Pharmacopoeia of the Russian Federation on the typhoid Vi polysaccharide vaccine (FS.3.3.1.0012.15).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>бактериальные эндотоксины</kwd><kwd>гель-тромб тест</kwd><kwd>вакцина брюшнотифозная Ви-полисахаридная</kwd><kwd>ЛАЛ-тест</kwd><kwd>тест на пирогенность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bacterial endotoxins</kwd><kwd>gel-clot test</kwd><kwd>typhoid Vi polysaccharide vaccine</kwd><kwd>LAL test</kwd><kwd>pyrogen test</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания ФГБУ «НЦЭСМП» Минздрава России № 056-00052-23-00 на проведение прикладных научных исследований (номер государственного учета НИР 121022000147-4).</funding-statement><funding-statement xml:lang="en">The study reported in this publication was carried out as part of publicly funded research  project No. 056-00052-23-00 and was supported by the Scientific Centre for Expert Evaluation of Medicinal Products (R&amp;D reporting  No. 121022000147-4).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Gorman A, Golovanov AP.
