Выполнено открытое нерандомизированное, одноцентровое, проспективное исследование, зарегистрированное на сайте Clinicaltrials.gov (# NCT02649517). В исследование включены 25 пациентов (84% составляют мужчины, фракция выброса (ФВ) ЛЖ ≤ 40%). Всем пациентам выполнена инвазивная коронарная ангиография и эндомиокардиальная биопсия (ЭМБ). Проведен иммуногистохимический (ИГХ) анализ ткани миокарда на экспрессию антигенов HHV-6, определение комплимента C1q, главного комплекса гистосовместимости класса II (MHC II), В-лимфоцитарного антигена (CD-19). Установлен сывороточный уровень анти-HHV-6 IgM и G с помощью иммуноферментного анализа (ИФА) c расчетом коэффициента позитивности (КП). За положительный результат принимали величину КП ≥ 0,8.</p></sec><sec><title>Результаты</title><p>Результаты. По результатам ЭМБ, у 15 (60%) из 25 включенных в исследование пациентов выявлена экспрессия антигенов HHV-6, из них в 10 случаях диагностирован HHV-6 – позитивный миокардит, у 5 больных – вирусоносительство. Вирусно-аутоиммунный характер миокардита, по данным морфологии, подтвержден в 3 (30%) случаях. По данным ИФА (18 больных), анти-HHV-6 IgM выявлены у 5 пациентов (28%), анти-HHV-6 IgG определялись чаще у 11 (61%). Одновременное наличие анти-HHV-6 IgM и анти-HHV-6 IgG было зарегистрировано у 2 (11%) пациентов. Кроме того, в 2 (11%) случаях анти-HHV-6 отсутствовали. У 8 (44%) пациентов с HHV-6 – позитивным миокардитом анти-HHV-6 IgM – в 3 (17%), анти-HHV-6 IgG – в 3 (17%) случаях определялись в сыворотке крови и отсутствовали анти-HHV-6 IgM, IgG – в 2 (11%) случаях. Вместе с тем при вирусоносительстве обнаруживался анти-HHV-6 IgM в 1 (20%) и анти-HHV-6 IgG в 4 (80%) случаев. У 5 (28%) пациентов при отсутствии экспрессии антигенов HHV-6 в 1 (5,6%) случае выявляли анти-HHV-6 IgM, в 2 (11%) случаях – анти-HHV-6 IgG. В зависимости от уровня анти-HHV-6 IgM в сыворотке крови пациенты разделены на 2 группы: 1-я группа – пациенты с положительным анти-HHV-6 IgM (n = 5), 2-я группа пациенты без положительного анти-HHV-6 IgM (n = 13). Среди клинико-инструментальных показателей различия установлены только в продолжительности анамнеза ХСН, она была большей в 1-й группе 22,5 [14,5; 75,5] против 11,0 [8,0; 12,0] (р = 0,045). Согласно результатам имммуногистохимического исследования, среди изученных маркеров в ткани миокарда значимых различий между группами не выявлено. Не установлена взаимосвязь между выраженностью экспрессии антигенов HHV-6 в ткани миокарда и сывороточными уровнями анти-HHV-6 IgM и IgG.</p></sec><sec><title>Выводы</title><p>Выводы. У пациентов с ОДХСН и/или неблагоприятным ремоделированием ЛЖ после полной реваскуляризации миокарда диагностирована высокая частота встречаемости экспрессии антигенов HHV-6 в ткани миокарда, степень выраженности которой не ассоциировалась с сывороточными уровнями анти-HHV-6 IgM и IgG.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To determine serum levels of immunoglobulin M (IgM) and G (IgG) antibodies to human herpes virus type 6 (HHV-6) (anti-HHV-6) and features of clinical and morphological portrait in patients with acute decompensated heart failure (ADHF) of ischemic genesis and/or adverse left ventricular (LV) remodeling.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. This open-label, nonrandomized, single-center, prospective trial was registered at clinicaltrials. gov (#NCT02649517) and comprised 25 patients (84% men) with ADHF and LV ejection fraction (EF) ≤ 40%. All patients underwent endomyocardial biopsy (EMB) with immunohistochemistry (IHC) analysis for the presence of HHV-6, compliment C1q, major histocompatibility complex of class II (MHC II), and B-lymphocyte antigen (CD19) as the markers of autoimmune reaction as well as the serum levels of anti-HHV-6 IgM and IgG. Serum levels of IgM and IgG were measured using enzymelinked immunosorbent assay (ELISA) with the calculation of positivity coefficient (PC) according to manufacturer instructions. The test results were interpreted as positive when PC value was greater than 0.8.</p></sec><sec><title>Results</title><p>Results. The endomyocardial biopsy study detected HHV-6 antigen expression in 15 (60%) out of 25 enrolled patients including 10 cases with diagnosed HHV-6-positive myocarditis and five patients with carriage of viruses. According to IHC, the autoimmune HHV-6 myocarditis was confirmed in three cases (30%). The data of ELISA (n = 18) detected anti-HHV-6 IgM in 5 patients (28%) and anti-HHV-6 IgG in 11 cases (61%). The simultaneous presence of both anti-HHV-6 IgM and IgG was detected in two patients (11%). In addition, anti-HHV-6 IgM and IgG were absent in two (11%) cases. Eight patients (44%) with HHV-6-positive myocarditis included three patients (17%) tested positive for serum anti-HHV-6 IgM, three patients (17%) tested positive for serum anti-HHV-6 IgG, and two patients (11%) who had nether anti-HHV-6 IgM nor anti-HHV-6 IgG in blood serum. Among virus carriers, one patient (20%) was tested positive for anti-HHV-6 IgM and four patients (80%) were tested positive for anti-HHV-6 IgG. The patients without HHV-6 antigen expression (n = 5, 28%) included one patient (5.6%) tested positive for anti-HHV-6 IgM and two patients (11%) tested positive for anti-HHV-6 IgG. The entire sample of patients was divided into two groups depending on the serum level of anti-HHV-6 IgM: group 1 comprised patients tested positive for anti-HHV-6 IgM (n = 5); group 2 comprised patients (n = 13) tested negative for anti-HHV-6 IgM. Clinical and instrumental parameters differed only in the duration of CHF history, which was greater in group 1 than in group 2 (11.0 [8.0; 12.0] vs. 22.5 [14.5; 75.5] months, respectively (p = 0.045). The groups did not significantly differ in the studied markers in myocardial tissue according to the results of IHC analysis. No associations were found between the severity of HHV-6 antigen expression and serum levels of anti-HHV-6 IgM and IgG.</p></sec><sec><title>Conclusion</title><p>Conclusion. Patients with ADHF and/or adverse LV remodeling after complete myocardial revascularization had higher percentage of HHV-6 antigen expression whose severity was not associated with the serum levels of anti-HHV-6 IgM and IgG.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>острая декомпенсация хронической сердечной недостаточности</kwd><kwd>неблагоприятное ремоделирование левого желудочка</kwd><kwd>вирус герпеса человека 6-го типа</kwd><kwd>ишемическая болезнь сердца</kwd><kwd>эндомиокардиальная биопсия</kwd><kwd>антитела к ННV-6 класса M и G</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acute decompensated heart failure</kwd><kwd>adverse left ventricular remodeling</kwd><kwd>human herpesvirus type 6</kwd><kwd>ischemic heart disease</kwd><kwd>endomyocardial biopsy</kwd><kwd>anti-HHV-6 IgM and IgG</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">Virani S.S., Alonso A., Benjamin E.J., Bittencourt M.S., Callaway C.W., Carson A.P. et al.
