Актуальным вопросом остается развитие снижения мышечной массы у пациентов с данным заболеванием вследствие ограничения физической активности, стероидной миопатии, сенильной саркопении и ряда других факторов.Цель исследования. Выявить различия параметров состава тела у пациентов с генерализованной аутоиммунной миастенией и здоровых лиц с помощью биоимпедансометрии.Материалы и методы. В  проспективное исследование включены 40  пациентов с  генерализованной аутоиммунной миастенией и 30  человек контрольной группы (здоровые добровольцы), которым проведены антропометрия и анализ компонентного состава тела с помощью биоимпедансного исследования.Результаты. У  пациентов с  аутоиммунной миастенией выявлен больший индекс массы тела (26,4 ± 5,2 против 23,9 ± 4,1 кг/м2; p = 0,045), однако распространенность ожирения в обеих группах не имела статистически значимых различий и составила 11,1 % среди пациентов с миастенией и 9,3 % в контрольной группе (p = 0,82). При этом процент жировой массы оказался существенно выше у пациентов с миастенией (32,4 ± 6,8 против 26,1 ± 5,2 %; p = 0,008), а доля лиц с избыточным содержанием жировой массы составила 57,1 % в основной группе и 26,1 % – в контрольной (p = 0,031). Кроме того, у пациентов с миастенией показатели тощей массы тела, активной клеточной массы и ее доли в составе тела были статистически значимо ниже, чем в контрольной группе: 55,4 ± 6,2 против 58,7 ± 5,1 кг, 24,1 ± 5,8 против 28,6 ± 4,7 кг и 44,8 ± 4,3 против 49,1 ± 3,5 % соответственно. Сниженная доля активной клеточной массы – менее 50 % у женщин и менее 53 % у мужчин – выявлялась у 68 % пациентов с миастенией и лишь у 20 % лиц контрольной группы. Аналогично сниженная доля скелетно-мышечной массы – менее 40 % у женщин и менее 45 % у мужчин – отмечалась у 54 % пациентов с миастенией против 13 % в контрольной группе. Минеральная масса костной ткани ниже у  пациентов с  миастенией: 2,21  кг против 2,53  кг в  контроле, то  есть на 0,32 ± 0,19 кг меньше (p = 0,02). У 32 % пациентов значения минеральной массы костной ткани были ниже условной нормы (2,0 кг), хотя указанное различие не достигло уровня статистической значимости (p = 0,052).Заключение. По  данным биоимпедансного исследования у  пациентов с  генерализованной аутоиммунной миастенией по сравнению со здоровыми добровольцами контрольной группы выявлены более высокие показатели индекса массы тела и доли жировой массы, сочетающиеся со снижением тощей, активной клеточной и скелетно-мышечной массы, а также минеральной массы костной ткани.</p></abstract><trans-abstract xml:lang="en"><p>Myasthenia gravis is the most common pathology from the group of neuromuscular synapse diseases. An urgent issue remains the development of a decrease in muscle mass in patients with this disease due to limited physical activity, steroid myopathy, senile sarcopenia, and a number of other factors.The aim of the study. To identify diff erences in body composition parameters in patients with myasthenia gravis and healthy individuals using bioimpedance measurement.Materials and methods. The prospective study included 40 patients with myasthenia gravis and 30 people in the control group (healthy volunteers) who underwent anthropometry and analysis of body composition using bioimpedance research.Results. Patients with  myasthenia gravis showed a  higher body mass index (26.4  ±  5.2 versus 23.9 ±  4.1  kg/m2; p =  0.045), however, the  prevalence of  obesity in  both groups had no  statistically signifi cant diff erences and amounted to 11.1 % among patients with myasthenia gravis and 9.3 % in the control group (p = 0.82). At the same time, the percentage of fat mass was signifi cantly higher in patients with myasthenia gravis: 32.4 ±  6.8 versus 26.1 ±  5.2 % (p = 0.008), and  the proportion of people with excess fat mass was 57.1 % in the main group and 26.1 % in the control group (p = 0.031). In addition, in patients with myasthenia gravis, lean body weight, active cell mass and its proportion in body composition were statistically signifi cantly lower than in the control group: 55.4 ± 6.2 versus 58.7 ± 5.1 kg, 24.1 ± 5.8 versus 28.6 ± 4.7 kg and 44.8 ± 4.3 versus 49.1 ± 3.5 %, respectively. A reduced proportion of active cell mass (less than 50 % in women and less than 53 % in men) was detected in 68 % of patients with myasthenia gravis and only in 20 % of the control group. Similarly, a reduced proportion of musculoskeletal mass – less than 40 % in women and less than 45 % in men – was observed in 54 % of patients with myasthenia gravis versus 13 % in the control group. Bone mineral mass is lower in patients with myasthenia gravis: 2.21 versus 2.53 kg in the control, that is, 0.32 ± 0.19 kg less (p = 0.02). In 32% of patients, bone mineral mass values were lower than the conditional norm (2.0 kg), although this diff erence did not reach the level of statistical signifi cance (p = 0.052).Conclusion. According to  the  bioimpedance study, patients with myasthenia gravis, compared with healthy volunteers in  the  control group, showed higher body mass index and  fat mass, combined with a decrease in lean, active cellular and musculoskeletal mass, as well as bone mineral mass.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биоимпеданс</kwd><kwd>аутоиммунные заболевания</kwd><kwd>аутоиммунная миастения</kwd><kwd>саркопения</kwd><kwd>анализ компонентного состава тела</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bioimpedance</kwd><kwd>autoimmune diseases</kwd><kwd>myasthenia gravis</kwd><kwd>sarcopenia</kwd><kwd>body component composition analysis</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">Pasnoor M, Wolfe GI, Barohn RJ.
