С высокой частотой (68%) выявляется интерстициальное поражение легких. При этом аутоиммунный профиль в данной группе мало изучен.</p><p>Цель – изучить уровень основных аутоантител (аутоАТ) у пациентов с ССД, позитивных по анти-U1РНП, и сравнить их частоту в данной группе и в группах пациентов с фенотипами ССД, ассоциированными с антицентромерными антителами (АЦА) и антителами к топоизомеразе I (анти-Scl70).</p><sec><title>Пациенты и методы</title><p>Пациенты и методы. Всего в исследование включено 144 больных, соответствующих критериям ССД (ACR/EULAR 2013). У 44 больных, позитивных по анти-U1РНП, определялись аутоАТ: ревматоидный фактор (РФ), антитела к циклическому цитруллинированному пептиду (АЦЦП), Ro (анти-Ro), La (анти-La), двуспиральной ДНК (анти-дсДНК), Sm (анти-Sm), кардиолипину (аКЛ), гистидил-тРНК-синтетазе (анти-Jo1), анти-Scl70, РНК-полимеразе III (анти-РНКП-III), АЦА – в двух точках. Проведен сравнительный анализ основной группы (больные ССД, позитивные по анти-U1РНП) и групп сравнения (больные ССД, позитивные по анти-Scl70 и АЦА).</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Среди пациентов с ССД, позитивных по анти-U1РНП, часто отмечаются перекресты (34%) с ревматоидным артритом (РА) и системной красной волчанкой (СКВ), а также сочетание с синдромом Шёгрена (СШ; 32,5%). В исследуемой группе часто выявлялись РФ (27%), анти-Ro (41%), анти-дсДНК (50%), редко – анти-Sm (9%), АЦЦП (9%), анти-La (7%), АЦА (11%), анти-Scl70 (9%), аКЛ (2%). Анти-Jo1 и анти-РНКП-III не были выявлены ни у одного больного. У пациентов с ССД, высокопозитивных по анти-U1РНП (более 2 верхних границ нормы), достоверно чаще встречались РФ, анти-Ro, анти-дсДНК (р&lt;0,01). В динамике анти-U1РНП, выявлявшиеся в дебюте заболевания, сохранялись у 75% больных. Исчезновение аутоАТ наблюдалось у пациентов с исходно низким титром анти-U1РНП. В группе больных, высокопозитивных по анти-U1РНП, при повторном обследовании сохранялась высокая частота выявления других аутоАТ. При сравнении трех групп особенностью основной группы было более частое присутствие других аутоАТ, наиболее значимыми из которых были анти-Ro. Их присутствие ассоциировались с СШ.</p></sec><sec><title>Заключение</title><p>Заключение. Больные ССД с гиперпродукцией анти-U1РНП, помимо клинических особенностей, отличаются от пациентов с основными фенотипами ССД более частым присутствием других аутоАТ. Для высокопозитивных по анти-U1РНП больных характерно стойкое повышение уровней РФ, анти-Ro, анти-дсДНК и редкое выявление ССД-специфических аутоАТ (АЦА, анти-Scl70 и анти-РНКП-III). </p></sec></abstract><trans-abstract xml:lang="en"><p>In anti-U1-ribonucleoprotein (anti-U1-RNP) antibody positive patients with systemic scleroderma (SSD), the clinical picture and course of the disease have specific features: there is a preponderance of its limited form; inflammatory damage to the joints and muscles comes to the fore; and cutaneous manifestations are mild. Moreover, a high frequency (68%) of interstitial lung disease is found. At the same time, the autoimmune profile in this group has been little studied.</p><sec><title>Objective</title><p>Objective: to investigate the level of major autoantibodies (autoAbs) in anti-U1RNP antibody positive patients with SSD and to compare the frequency of the autoAbs in this group and in the groups of patients with SSD phenotypes associated with anti-centromere antibodies (ACA) and anti-topoisomerase I (anti-Scl70) antibodies.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. The investigation enrolled a total of 144 patients meeting the 2013 ACR/EULAR SSD classification criteria. Forty-four anti-U1RNP antibody positive patients were found to have autoAbs, rheumatoid factor (RF), anti-cyclic citrullinated peptide (ACCP), anti-Ro, anti-La, anti-double-stranded DNA (anti-dsDNA), anti-Smith (anti-Sm), anti-cardiolipin (aCL), anti-histidyl tRNA synthetase (anti-Jo1), anti-Scl70, and anti-RNA polymerase III (anti-RNAP-III) antibodies, and ACA in two points. The study group (anti-U1RNP antibody positive patients with SSD) and the comparison groups (anti-Scl70 and ACA positive patients) were comparatively analyzed.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. Anti-U1RNP antibody positive patients with SSD were commonly observed to have overlaps (34%) with rheumatoid arthritis and systemic lupus erythematosus, as well as concurrence with Sjögren’s syndrome (SS) (32.5%). The study group was found to have frequently RF (27%), anti-Ro (41%), anti-dsDNA (50%) antibodies, rarely anti-Sm (9%), ACCP (9%), anti-La (7%), ACA (11%), anti-Scl70 (9%), and aCL (2%) antibodies. Anti-Jo1 and anti-RNAP-III antibodies were not detected in any patient. SSD patients who were highly positive for anti-U1RNP antibodies (more than 2 upper limits of the reference range) significantly more frequently exhibited RF, anti-Ro and anti-dsDNA antibodies (p&lt;0.01). Over time, anti-U1RNP antibodies detected at the onset of the disease persisted in 75% of patients. autoAbs were observed to disappear in patients with a low baseline titer of anti-U1RNP antibodies. Re-examination demonstrated that the detection rate of other autoAbs remained high in the group of patients who were highly positive for anti-U1RNP antibodies. Comparison of the three groups showed that the specific feature of the study group was the more frequent presence of other autoAbs, among which anti-Ro antibodies were most important. Their presence was associated with SS.</p></sec><sec><title>Conclusion</title><p>Conclusion. In addition to clinical features, patients with SSD and anti-U1RNP antibody overproduction differ from those with major SSD phenotypes by the more frequent presence of other autoAbs. Persons who are highly positive for anti-U1RNP show the steady-state elevated levels of RF, anti-Ro and anti-dsDNA antibodies and the rare detection of SSD-specific autoAbs (ACA, anti-Scl70 and anti-RNAP-III). </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>системная склеродермия</kwd><kwd>аутоантитела</kwd><kwd>U1-РНП</kwd><kwd>синдром Шегрена</kwd><kwd>перекрестный синдром</kwd></kwd-group><kwd-group xml:lang="en"><kwd>systemic scleroderma</kwd><kwd>autoantibodies</kwd><kwd>U1-RNP</kwd><kwd>Sjögren’s syndrome</kwd><kwd>overlap syndrome</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">Гусева НГ.
