Степень их выраженности может варьироваться от бессимптомного снижения почечной функции до жизнеугрожающих повреждений, которые представляют собой сложную терапевтическую проблему. Ритуксимаб (РТМ) применяется в лечении ССД и других аутоиммунных заболеваний с многообещающими результатами, однако его влияние на функцию почек изучено недостаточно.</p><p>   Цель исследования – оценить состояние функции почек на фоне комплексной терапии, включающей РТМ, у больных ССД в течение длительного (не менее 1 года) наблюдения.</p><sec><title>   Материал и методы</title><p>   Материал и методы. В исследование включено 90 больных ССД, которых обследовали как минимум дважды – до и через 1–3,5 года после начала лечения РТМ. Почечную функцию оценивали по скорости клубочковой фильтрации (СКФ), рассчитанной по формуле CKD-EPI. Определяли также стадии хронической болезни почек (ХБП), уровень артериального давления, суточную протеинурию, кожный счет, активность и показатели легочной функции – форсированную жизненную емкость легких и диффузионную способность легких.</p><p>   Результаты и обсуждение. На фоне комплексной терапии РТМ в конце наблюдения отмечалось статистически значимое снижение СКФ в группе больных в целом. В то же время у большинства пациентов с исходно сохранной СКФ функция почек оставалась стабильной, а число больных с ХБП уменьшилось на 25 % – с 20 до 15. Более чем у половины больных, исходно имевших ХБП, после терапии СКФ увеличилась (n = 11) или стабилизировалась (n = 2), и лишь у 7 пациентов она статистически незначимо снизилась, при этом только в 2 случаях наблюдалось развитие более продвинутой стадии ХБП. Детально рассмотрены результаты лечения 2 больных, которые ранее перенесли склеродермический почечный криз (СПК).</p></sec><sec><title>   Заключение</title><p>   Заключение. В данной работе не отмечено существенного влияния лечения РТМ на СКФ и степень ХБП. Большинство больных имели стабильную функцию почек, у пациентов с исходно незначительной степенью ХБП была выявлена тенденция к стабилизации почечной функции. Значимое снижение СКФ на фоне длительной терапии, отмеченное в группе больных в целом, по-видимому, объясняется нарастанием почечной недостаточности у пациентов, исходно имевших выраженное склеродермическое поражение почек, в частности, вследствие СПК. Требуется дальнейшее изучение влияния терапии РТМ на функцию почек у пациентов с ССД.</p></sec></abstract><trans-abstract xml:lang="en"><p>   In systemic sclersis (SSc), different types of renal involvement occur. Their severity can range from asymptomatic deterioration of renal function to life-threatening damage, which is a complex therapeutic problem. Rituximab (RTM) has been used in the treatment of SSc and other autoimmune diseases with promising results, but its effect on renal function has not been adequately studied.</p><sec><title>   Objective</title><p>   Objective: to evaluate the renal function during complex therapy, including RTM, in patients with SSc over a long-term follow-up (at least 1 year).</p></sec><sec><title>   Material and methods</title><p>   Material and methods. The study included 90 patients with SSc who were examined at least twice – before and 1–3.5 years after initiation of RTM treatment. Renal function was assessed by glomerular filtration rate (GFR) calculated according to the CKD-EPI formula. The stages of chronic kidney disease (CKD), blood pressure, daily proteinuria, skin score, activity, and indicators of lung function – forced vital capacity and diffusing capacity of the lungs – were also determined.</p><p>   Results and discussion. Against the background of complex therapy with RTM, there was a statistically significant decrease in GFR in the entire group of patients at the end of observation. On the other hand, renal function remained stable in the majority of patients with initially preserved GFR and there was a 25 % decrease – from 20 to 15 patients – in the number of patients with CKD. In more than half of the patients who initially had CKD, GFR increased (n = 11) or stabilized (n = 2) after therapy, and it decreased in a statistically insignificant manner in only 7 patients, whereas the development of a more advanced stage of CKD was observed in only 2 cases. The results of the treatment of 2 patients who had previously experienced scleroderma renal crisis (SRC) are reviewed in detail.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. In this study, there was no significant effect of RTM treatment on GFR and grade of CKD. Most patients had stable renal function; patients with an initial low grade of CKD showed a tendency toward stabilization of renal function. A significant decrease in GFR during long-term therapy noted in the entire patient group appears to be explained by an increase in renal insufficiency in patients with initially severe scleroderma renal damage, particularly due to SRC. Further studies on the effects of RTM therapy on renal function in patients with SSc are needed.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>системная склеродермия</kwd><kwd>склеродермический почечный криз</kwd><kwd>хроническая болезнь почек</kwd><kwd>скорость клубочковой фильтрации</kwd><kwd>ритуксимаб</kwd></kwd-group><kwd-group xml:lang="en"><kwd>systemic scleroderma</kwd><kwd>scleroderma renal crisis</kwd><kwd>chronic kidney disease</kwd><kwd>glomerular filtration rate</kwd><kwd>rituximab</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The investigation has not been sponsored</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Gabrielli A, Avvedimento EV, Krieg T.
