В динамике в течение 6–12 месяцев обследованы 24 пациента (средний возраст — 38,2 ± 4,4 года) с ВЗК средней и легкой степени тяжести заболевания, из них 10 пациентов — с язвенным колитом, 10 — с болезнью Крона, 4 — с неклассифицируемым колитом: первое обследование — в стадии обострения, второе — в стадии ремиссии. У 48 дополнительно обследованных пациентов с ВЗК в стадии ремиссии (25 пациентов с язвенным колитом, 15 — с болезнью Крона, 8 — с неклассифицируемым колитом) проведен мониторинг течения заболевания в течение последующих 12 месяцев. Группу сравнения составили 53 человека, сопоставимые по возрасту с пациентами основных групп. Исследование состава жирных кислот мембран эритроцитов и сыворотки крови проведено с помощью системы газовой хромато-массспектрометрии на основе трех квадруполей Agilent 7000B («Agilent Technologies Inc.», США).Результаты. В стадии обострения у пациентов с ВЗК выше суммарное содержание насыщенных жирных кислот (НЖК) в мембранах эритроцитов по сравнению с группой контроля (p = 0,006) и, напротив, ниже содержание ненасыщенных жирных кислот (ННЖК) (p = 0,005), преимущественно за счет полиненасыщенных жирных кислот (ПНЖК) (p = 0,026), а именно — омега-6 ПНЖК (p = 0,011). Ремиссия ВЗК ассоциирована с повышением уровня ряда НЖК в сыворотке крови — маргариновой С17:0 (p = 0,024), арахиновой С20:0 — в мембранах эритроцитов и сыворотке (p = 0,0001 и p = 0,019 соответственно); со снижением суммарного содержания мононенасыщенных жирных кислот в мембранах эритроцитов (p = 0,022); повышением суммарной концентрации ПНЖК, как за счет омега-3 ПНЖК (p = 0,0008), так и омега-6 ПНЖК (p = 0,033), в мембранах эритроцитов по сравнению с группой здоровых лиц.Стадия обострения у пациентов с ВЗК, обследованных в динамике, ассоциирована с более высокими уровнями стеариновой жирной кислоты С18:0 (p = 0,005), отношений НЖК/ННЖК (p = 0,034), НЖК/ПНЖК (p = 0,039) в мембранах эритроцитов, сывороточным уровнем арахиновой жирной кислоты С20:0 (p = 0,008) и, напротив, более низким содержанием ННЖК в мембранах эритроцитов — эйкозапентаеновой С20:5n-3 (p = 0,0023), эйкозадиеновой C20:2n-6 (p = 0,0027), гексадекадиеновой С16:2n-6 (p = 0,006), докозатетраеновой С22:4n-6 (p = 0,008) и альфа-линоленовой С18:3n-3 (p = 0,039).Комбинированная «панель» жирных кислот, включающая уровни C20:2n-6, C18:0 в мембранах эритроцитов и содержание C20:0 в сыворотке крови, обеспечила AUC 0,683 (95 % ДИ: 0,500–0,844), чувствительность 91,4 % и специфичность 68,3 %.Уровни жирных кислот С20:5n-3, С20:2n-6, С18:0, С16:2n-6, С22:4n-6, С18:3n-3, соотношений НЖК/ННЖК, НЖК/ПНЖК в мембранах эритроцитов и содержание С20:0 в сыворотке крови, использованные как биомаркеры — предикторы развития обострения у пациентов с ВЗК, находившихся в стадии ремиссии, предсказали развитие обострения ВЗК через 2–4 месяца в случае максимально измененных уровней жирных кислот, через 6–8 месяцев — при умеренно измененных уровнях жирных кислот, сохранение ремиссии в течение 12 месяцев — при минимально измененных уровнях жирных кислот.Заключение. Жирные кислоты мембран эритроцитов и сыворотки крови следует рассматривать как перспективные маркеры для дальнейших исследований, связанных с диагностикой и предикцией развития обострения при ВЗК.</p></abstract><trans-abstract xml:lang="en"><p>Aim: to study the levels of fatty acids in the membranes of erythrocytes and blood serum in patients with inflammatory bowel diseases (IBD) examined over time, as possible predictors of exacerbation of the disease.Materials and methods. Over a period of 6–12 months, 24 patients (mean age — 38.2 ± 4.4 years) with IBD with of moderate and mild severity of the disease were examined, of which 10 patients had ulcerative colitis, 10 — Crohn’s disease, 4 — unclassified colitis: the first examination was in the acute stage, the second was in the remission stage. In 48 additionally examined patients with IBD in remission (25 patients with ulcerative colitis, 15 — with Crohn’s disease, 8 — with unclassified colitis), the course of the disease was monitored over the next 12 months. The comparison group included 53 people comparable to the main groups in age. The study of the composition of fatty acids (FAs) in the membranes of erythrocytes and blood serum was carried out using a gas chromatograph mass spectrometry system based on three quadrupoles Agilent 7000B (Agilent Technologies Inc., USA).Results. In the acute stage, patients with IBD have a higher total content of saturated fatty acids (SFAs) in erythrocyte membranes compared to the control group (p = 0.006), and, on the contrary, lower levels of unsaturated fatty acids (UFAs) (p = 0.005), mainly due to polyunsaturated FAs (PUFAs) (p = 0.026), namely omega-6 PUFAs (p = 0.011).Remission of IBD is associated with an increase in the level of a number of SFAs in the blood serum — margaric C17:0 (p = 0.024), arachidic acid (C20:0) — in erythrocyte membranes and serum (p = 0.0001 and p = 0.019, respectively), with a decrease in the total content of monounsaturated FAs in erythrocyte membranes (p = 0.022), an increase in the total concentration of PUFAs due to both omega-3 PUFAs (p = 0.0008) and omega-6 PUFAs (p = 0.033) in erythrocyte membranes compared with a group of healthy individuals.The exacerbation stage in patients with IBD examined over time is associated with higher levels of stearic FA C18:0 (p = 0.005), SFA/UFA (p = 0.034) and SFA/PUFA (p = 0.039) ratios in erythrocyte membranes, serum level of arachidic FA C20:0 (p = 0.008), and, on the contrary, lower content of UFAs in erythrocyte membranes — eicosapentaenoic C20:5n-3 (p = 0.0023), eicosadienoic C20:2n-6 (p = 0.0027), hexadecadienoic C16:2n-6 (p = 0.006), docosatetraenoic C22:4n-6 (p = 0.008) and alpha-linolenic C18:3n-3 (p = 0.039).A combined “panel” of fatty acids, including the levels of C20:2n-6, C18:0 in erythrocyte membranes and the content of C20:0 in blood serum, provided an AUC of 0.683 (95 % CI: 0.500–0.844), sensitivity 91.4 %, specificity 68.3 %.Levels of C20:5n-3, C20:2n-6, C18:0, C16:2n-6, C22:4n-6, C18:3n-3 fatty acids, SFA/UFA and SFA/PUFA ratios in erythrocyte membranes and content C20:0 in blood serum, used as biomarkers — predictors of the development of exacerbation in patients with IBD who were in remission, predicted the development of exacerbation of IBD after 2–4 months in the case of maximally changed levels of FAs, after 6–8 months — with moderately changed levels FAs, maintaining remission for 12 months — with minimally changed FAs levels.Conclusion. Fatty acids of erythrocyte membranes and blood serum should be considered as promising markers for further studies related to the diagnosis and prediction of exacerbation in IBD.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>воспалительные заболевания кишечника</kwd><kwd>предикция обострения</kwd><kwd>жирные кислоты</kwd><kwd>мембраны эритроцитов</kwd><kwd>сыворотка крови</kwd></kwd-group><kwd-group xml:lang="en"><kwd>inflammatory bowel diseases</kwd><kwd>prediction of exacerbation</kwd><kwd>fatty acids</kwd><kwd>erythrocyte membranes</kwd><kwd>blood serum</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена по Государственному заданию в рамках бюджетной темы «Изучение молекулярно-генетических и молекулярно-биологических механизмов развития распространенных терапевтических заболеваний в Сибири для совершенствования подходов к их ранней диагностике и профилактике», 2024–2028 гг.
