Однако присоединение во второй половине гестации боли в спине и, возможно, в энтезисах, связанной с физиологически протекающей беременностью, требует проведения дифференциальной диагностики для уточнения генеза боли и выбора правильной тактики ведения пациенток, что и обусловливает актуальность данного исследования.</p><p>Цель исследования – изучить динамику боли в спине, энтезисах и паховой области, а также функционального статуса у пациенток с АС в течение беременности и выявить клинические признаки, наиболее точно отражающие воспалительную активность на фоне гестации.</p><sec><title>Пациенты и методы</title><p>Пациенты и методы. В основную группу включено 36 беременных с достоверным диагнозом АС по модифицированным Нью-Йорским критериям (1984). Средний возраст – 31,6±4,8 года, средний возраст на момент начала АС – 21,8±10,9 года, продолжительность болезни – 134,9±89,3 мес. В контрольную группу вошли 30 здоровых беременных с отсутствием боли в спине и артритов в анамнезе, средний возраст – 28,2±4,5 года. Беременные обеих групп были сопоставимы по паритету. Визиты проводились на 10–11-й, 20–21-й и 31–32-й неделях беременности. Интенсивность боли оценивали по числовой рейтинговой шкале (ЧРШ), функциональный статус – по BASFI. Для оценки энтезита использовали счет MASES.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. В течение беременности боль в спине беспокоила 94% больных АС, ее интенсивность по триместрам составила 3 [2; 4], 4 [3; 5,5], 3 [2; 7] и была выше, чем у здоровых беременных (p&lt;0,0001). В основной группе с увеличением срока гестации отмечалось нарастание интенсивности ночной боли (n=23–28): I триместр – 2 [1; 4]; II – 3 [0; 5]; III – 3 [1; 6] (p&lt;0,05 при сравнении I и II, I и III триместров) и продолжительности утренней скованности (n=28–30): 10 [5; 20], 15 [10; 55] и 15 [5; 60] мин соответственно. При этом количество женщин, отметивших улучшение после физических упражнений (85–63%) и отсутствие улучшения в покое (88–56%), уменьшилось (p&lt;0,05 при сравнении I и II, III триместров).</p><p>В контрольной группе утренняя скованность в спине была у 1, а ночная боль – у 3 пациенток. На уменьшение боли в спине после физических упражнений здоровые беременные чаще указывали в III триместре (66,7% имеющих боль) по сравнению с I (20% имеющих боль; p&lt;0,05).</p><p>У больных АС К III триместру наблюдалось изменение характера боли в спине: 43,7% пациенток отметили улучшение в состоянии покоя, 42,4% – усиление боли после физических упражнений, при этом частота элементов механической боли в спине была меньше, чем в контрольной группе (p&lt;0,05).</p><p>Интенсивность боли в паховой области (2,4±1,9; 3,3±2,4; 4,3±3,0 соответственно в I и II, III триместрах) не различалась у больных АС с кокситом и энтезитом в области таза и без них. Частота энтезита и счет MASES в основной группе были выше, чем в контрольной (p&lt;0,05), счет MASES увеличивался со сроком беременности, составляя 0 [0; 1] в I триместре и 2 [0; 3] в III триместре (p&lt;0,05).</p><p>Функциональные нарушения в ходе гестации нарастали в обеих группах, различие значений BASFI между группами выявлено только в III триместре: 3,5±2,8 и 1,7±1,2 соответственно (p&lt;0,05).</p></sec><sec><title>Выводы</title><p>Выводы. В ходе гестации боль в спине и функциональные нарушения у больных АС усиливаются. Ночная боль в спине, утренняя скованность и энтезит отражают воспалительную активность АС на фоне беременности. В III триместре у 40% женщин с АС присоединяется механическая боль в спине. Критерии воспалительной боли в спине и BASFI требуют адаптации для их использования у беременных.</p></sec></abstract><trans-abstract xml:lang="en"><p>Inflammatory rhythm back pain and enthesitis are one of the main clinical manifestations of ankylosing spondylitis (AS), which increase in severity during pregnancy. However, addition of back pain and, possibly, enthesis in the second half of gestation, which is associated with normal pregnancy, needs to make a differential diagnosis for clarifying the genesis of pain and choosing the right management tactics, which determines the relevance of this study.</p><sec><title>Objective</title><p>Objective: to investigate the course of pain in the back, enthesis, and inguinal region, as well as the functional status in AS patients during pregnancy and to reveal clinical signs that most accurately reflect inflammatory activity during gestation.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. A study included 36 pregnant women with a reliable diagnosis of AS according to the modified New York criteria (1984). Their mean age was 31.6±4.8 years, the mean age at the onset of AS was 21.8±10.9 years; the duration of the disease was 134.9±89.3 months. A control group comprised 30 healthy pregnant women with no history of back pain and arthritis; their mean age was 28.2±4.5 years. The pregnant women of both groups were matched for parity. They made visits at 10–11, 20–21, and 31–32 weeks of pregnancy. Pain intensity was estimated using the numerical pain rating scale (NPRS) and the functional status was assessed by the Bath Ankylosing Spondylitis Functional Index (BASFI). The Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) was used to assess enthesitis.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. During pregnancy, 94% of AS patients had back pain; its intensity by trimesters was 3 [2; 4], 4 [3; 5.5], 3 [2; 7] and was higher than in healthy pregnant women (p&lt;0.0001). In the study group, there was a rise in pain intensity at night with increasing gestational age (n=23–28): 2 [1; 4] in the first trimester; 3 [0; 5] II in the second trimester; 3 [1; 6] in the third trimester (p&lt; when comparing the first, second, and third trimesters) and an increase in the duration of morning stiffness (n= ): 10 [5; 20], 15 [10; 55], and 15 [5; 60] min, respectively. Moreover, the number of women who reported improvements after exercise (85–63%) and no improvement at rest (88–56%) declined (p&lt;0.05 when comparing the first, second, and third trimesters).</p><p>In the control group, 1 and 3 patients had morning back stiffness and night pain, respectively. The healthy pregnant women more frequently reported a reduction in back pain after exercise in the third trimester (66.7% of those with pain) than in the first trimester (20% of those with pain) (p&lt;0.05).</p><p>By the third trimester, the patients with AS showed a change in the nature of back pain: 43.7% of the patients reported an improvement at rest; 42.4% noted an increase in pain after exercise, while the frequency of elements of mechanical back pain was less than that in the control group (p &lt; 0.05).</p><p>The intensity of groin pain (2.4±1.9, 3.3±2.4, and 4.3±3.0 in the first, second, and third trimesters, respectively) did not differ in AS patients with and without coxitis or pelvic enthesitis. The frequency of enthesitis and MASES scores in the study group were higher than in the control group (p&lt;0.05), the MASES scores increased with gestational age, amounting to 0 [0; 1] in the first trimester and 2 [0; 3] in the third trimester (p&lt;0.05).</p><p>Functional disorders during pregnancy increased in both groups; there was a difference in BASFI scores between the groups only in the third trimester: 3.5±2.8 and 1.7±1.2, respectively (p&lt;0.05).</p></sec><sec><title>Conclusion</title><p>Conclusion. Back pain and functional disorders increase in AS patients during gestation. Night back pain, morning stiffness, and enthesitis reflect the inflammatory activity of AS during pregnancy. Mechanical back pain joins in 40% of women with AS in the third trimester. The criteria for inflammatory back pain and BASFI require adaptation when used in pregnant women.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>анкилозирующий спондилит</kwd><kwd>беременность</kwd><kwd>боль в спине</kwd><kwd>энтезиты</kwd><kwd>BASFI</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ankylosing spondylitis</kwd><kwd>pregnancy</kwd><kwd>back pain</kwd><kwd>enthesitis</kwd><kwd>BASFI</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">Кричевская ОА, Гандалоева ЗM, Дубинина ТВ.
