Провести сравнительный анализ интенсивности перекисного окисления липидов и показателей антиоксидантной системы в нейтрофилах крови больных первичными и рецидивными саркомами мягких тканей (СМТ) в зависимости от пола и возраста.</p></sec><sec><title>Пациенты и методы</title><p>Пациенты и методы. В исследование был включен 81 пациент, в том числе 48 пациентов с первичными СМТ, 5 пациентов с продолженным ростом и 28 с рецидивами СМТ. Пациенты были разделены по полу и возрасту, у них были исследованы в нейтрофилах крови уровень продуктов перекисного окисления липидов (ПОЛ), активность супероксиддисмутазы (СОД), суммарная пероксидазная активность (СПА), активность глутатионпероксидазы (ГПО) и содержание восстановленного глутатиона (ВГ) общепринятыми спектрофотометрическими методами. Группы сравнения (доноры) составили 12 мужчин и 17 женщин, разделенных на такие же возрастные подгруппы: ≤ 45 лет и &gt; 45 лет.</p></sec><sec><title>Результаты</title><p>Результаты. У доноров наблюдалось многократное снижение соотношения СОД/СПА с возрастом, особенно у женщин, а у мужчин это сопровождалось и возрастным снижением активности ГПО. При первичных саркомах у женщин старшей возрастной группы и у мужчин при продолженном росте и рецидивах имело место увеличение диеновых конъюгатов (ДК). У мужчин в возрасте более 45 лет было обнаружено повышение СОД, СПА и ГПО. Для женщин старшей возрастной группы была характерна активация СОД и ГПО, выраженная при рецидивном процессе в значительно большей степени, чем у мужчин, при этом у женщин наблюдалось увеличение содержания ВГ. Особенно значимым было повышение обоих компонентов глутатионовой системы и активности СОД при развитии у женщин рецидивов в сроки, превышающие три года, что сопровождалось снижением содержания ДК.</p></sec><sec><title>Заключение</title><p>Заключение. Для нейтрофилов характерным является повышение содержания ДК у больных обоего пола старшей возрастной группы при первичных и рецидивных СМТ с максимально высоким его содержанием при продолженном росте и рецидивах у мужчин. Активность ГПО, увеличенная как у мужчин, так и у женщин в старшей возрастной группе при всех вариантах развития СМТ, может играть важную роль в антиоксидантной защите клеток крови при СМТ. Так, наиболее выраженная активация ГПО, сопровождаемая максимальным приростом восстановленного глутатиона и активацией СОД, способствует снижению уровня ДК при отсутствии прироста малонового диальдегида при медленном процессе рецидивирования у женщин.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study. To carry out a comparative analysis of lipid peroxidation intensity and antioxidant system indices in blood neutrophils of patients with primary and relapsed soft tissue sarcomas (STS) depending on sex and age.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. Of the 81 patients included in the study, 48 had primary STS, 5 patients with continued growth, and 28 patients with recurrent STS. The patients were divided by sex and age; the level of lipid peroxidation products, superoxide dismutase (SOD) activity, total peroxidase activity (TPA), glutathione peroxidase (GPx) activity and reduced glutathione (RG) content in blood neutrophils were investigated by conventional spectrophotometric methods. The comparison groups (donors) consisted of 12 men and 17 women divided into the same age subgroups: ≤ 45 years and &gt; 45 years.</p></sec><sec><title>Results</title><p>Results. In donors, there was a multiple decrease in the SOD/TPA ratio with age, especially in women, and in men this was accompanied by an age-related decrease in GPx activity. In primary sarcomas in older women and in men with continued growth and recurrence, there was an increase in diene conjugates (DC). In men over 45 years of age, there was an increase in SOD, TPA, and GPx. Women of the older age group were characterized by activation of SOD and GPx, expressed in the relapsed process to a significantly greater extent than in men, and an increase in RG was observed in women. The increase in both components of the glutathione system and SOD activity was especially significant in the development of relapses in women for periods exceeding three years, which was accompanied by a decrease in DC content.</p></sec><sec><title>Conclusions</title><p>Conclusions. Neutrophils are characterized by an increase in DC content in patients of both sexes in the older age group with primary and recurrent STS, with its highest content in men with continued growth and relapses. GPx activity, increased in both men and women in the older age group in all variants of STS development, may play an important role in the antioxidant protection of blood cells in STS. Thus, the most pronounced activation of GPx, accompanied by a maximum increase in reduced glutathione and activation of SOD, contributes to a decrease in the level of DC and the absence of MDA increase in women with slow development of recurrences.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>саркомы мягких тканей</kwd><kwd>пол и возраст больных</kwd><kwd>нейтрофилы</kwd><kwd>малоновый диальдегид</kwd><kwd>диеновые конъюгаты</kwd><kwd>антиоксидантные ферменты</kwd><kwd>глутатион</kwd></kwd-group><kwd-group xml:lang="en"><kwd>soft tissue sarcomas</kwd><kwd>sex and age of patients</kwd><kwd>neutrophils</kwd><kwd>malondialdehyde</kwd><kwd>diene conjugates</kwd><kwd>antioxidant enzymes</kwd><kwd>glutathione</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">Carnevale S, Ghasemi S, Rigatelli A, Jaillon S.
