Pain is considered as the most significant clinical symptom and maladaptive manifestation of both migraine and endometriosis. Studying the relationship between the clinical manifestations of pain syndrome in patients with endometriosis and migraine is important, since it will contribute to the understanding of the mechanisms of comorbidity of these diseases.</p><sec><title>Objective</title><p>Objective: to analyze the features of pain syndrome in patients with migraine and genital endometriosis to clarify the neurogenic mechanisms of their comorbid relationship.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. A total of 125 patients who had gone to a gynecologist for endometriosis were examined for the presence of migraine. In accordance with the inclusion criteria, 79 patients (mean age, 34.68±7.11 years) with genital endometriosis confirmed by diagnostic laparoscopy participated in the further study. Two age-matched groups were formed: a study group consisted of 38 patients with endometriosis and concomitant migraine; a comparison group included 41 patients with endometriosis without migraine. All the patients underwent clinical neurological examination, questionnaire survey, pelvic ultrasound, assessment of the severity of pelvic pain according to the pelvic pain index, and determination of the level of central sensitization (CS) using the CS Inventory.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. 42% out of the 125 patients who had visited their gynecologist for endometriosis suffered from concomitant migraine, which confirms the comorbidity of these diseases. Chronic pelvic pain (CPP), dysmenorrhea, dyspareunia, and dyschesia were more common in patients with endometriosis and migraine; there were more patients with asymptomatic endometriosis in the comparison group. The patients of the two groups did not differ in the presentation of different forms of endometriosis, which favors the leading role of central mechanisms in the pathogenesis of pain syndrome in comorbidity of these diseases.In addition, there was a statistically significant increase in the presentation of CPP and dysmenorrhea in patients with chronic migraine compared to those with episodic migraine and to those without migraine. Significantly higher levels of CS according to CSI and pelvic pain index were found in patients with chronic migraine and endometriosis, which suggests that CS plays a key role in the comorbidity of these diseases.</p></sec><sec><title>Conclusion</title><p>Conclusion. The phenomenon of CS is one of the mechanisms of comorbidity of migraine and endometriosis, contributes to both the worsening of various painful manifestations of endometriosis and the increase in migraine attacks, thereby causing obvious maladaptation in patients. The role of CS in the comorbidity of migraine and endometriosis opens up possibilities for the elaboration of a comprehensive interdisciplinary approach to treating these diseases.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Мигрень часто сочетается с эндометриозом, однако механизмы коморбидности этих состояний недостаточно изучены. Боль рассматривается в качестве наиболее значимого клинического симптома и дезадаптирующего проявления как мигрени, так и эндометриоза. Исследование взаимосвязи клинических проявлений болевого синдрома у пациенток с эндометриозом и мигренью представляется важным, поскольку будет способствовать пониманию механизмов коморбидности данных заболеваний.</p><p>Цель исследования – анализ особенностей болевого синдрома у пациенток с мигренью и генитальным эндометриозом для уточнения нейрогенных механизмов их коморбидной связи.</p><sec><title>Пациенты и методы</title><p>Пациенты и методы. Всего на наличие мигрени было обследовано 125 пациенток, обратившихся к гинекологу по поводу эндометриоза. В соответствии с критериями включения в дальнейшем исследовании приняли участие 79 пациенток (средний возраст 34,68±7,11 года) с лапароскопически подтвержденным диагнозом «генитальный эндометриоз». Сформированы две сопоставимые по возрасту группы: основную составили 38 пациенток с эндометриозом и сопутствующей мигренью, группу сравнения – 41 пациентка с эндометриозом без мигрени. Всем пациенткам проводилось клиническое неврологическое исследование, анкетирование, УЗИ органов малого таза, оценка выраженности тазовой боли по индексу тазовой боли и определение уровня центральной сенситизации (ЦС) по опроснику CSI.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Из 125 пациенток, обратившихся к гинекологу по поводу эндометриоза, 42,4% страдали сопутствующей мигренью, что подтверждает коморбидность данных заболеваний. Хроническая тазовая боль (ХТБ), дисменорея, диспареуния, дисхезия чаще встречались у пациенток с эндометриозом, страдающих мигренью; в группе сравнения было больше пациенток с бессимптомным течением эндометриоза. Пациентки двух групп не различались по представленности различных форм эндометриоза, что свидетельствует в пользу ведущей роли центральных механизмов в патогенезе болевого синдрома при коморбидности данных заболеваний. Кроме того, было показано статистически значимое увеличение представленности ХТБ и дисменореи у пациенток с хронической мигренью по сравнению с больными с эпизодической мигренью и пациентками без мигрени. Обнаружены значимо более высокие уровень ЦС по опроснику CSI и индекс тазовой боли у пациенток с хронической мигренью и эндометриозом, что свидетельствует о ключевой роли ЦС при коморбидности данных заболеваний.</p></sec><sec><title>Заключение</title><p>Заключение. Феномен ЦС является одним из механизмов коморбидности мигрени и эндометриоза, способствует как усилению различных болевых проявлений эндометриоза, так и учащению приступов мигрени, тем самым вызывая выраженную дезадаптацию пациенток. Роль ЦС в коморбидности мигрени и эндометриоза открывает возможности для разработки комплексного междисциплинарного подхода в лечении данных заболеваний.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>мигрень</kwd><kwd>эндометриоз</kwd><kwd>коморбидность</kwd><kwd>боль</kwd><kwd>центральная сенситизация</kwd><kwd>дисменорея</kwd><kwd>диспареуния</kwd><kwd>болевой синдром</kwd><kwd>менархе</kwd><kwd>тазовая боль</kwd></kwd-group><kwd-group xml:lang="en"><kwd>migraine</kwd><kwd>endometriosis</kwd><kwd>comorbidity</kwd><kwd>pain</kwd><kwd>central sensitization</kwd><kwd>dysmenorrhea</kwd><kwd>dyspareunia</kwd><kwd>pain syndrome</kwd><kwd>menarche</kwd><kwd>pelvic pain</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">Maitrot-Mantelet L, Hugon-Rodin J, Vatel M, et al.
