КЛИНИЧЕСКАЯ И ИММУНОЛОГИЧЕСКАЯ ЭФФЕКТИВНОСТЬ РЕКОМБИНАНТНОГО ИНТЕРФЕРОНА альфа-2b ПРИ ОСТРОМ ЭПШТЕЙНА-БАРР ВИРУСНОМ МОНОНУКЛЕОЗЕ У ДЕТЕЙ ДОШКОЛЬНОГО ВОЗРАСТА

Conducted clinical and immunological examination of 51 children with acute Epstein-Barr viral mononucleosis (EBV) in age from 1 year to 7 years. All children diagnosed with a moderate degree of the disease. In the treatment of 25 people (comparison group) used the standard treatment (pathogenetic, symptomatic), treatment 26 people (main group) included the use as antiviral and immunotropic means of the preparation of human recombinant interferon Alfa-2b in the form of rectal suppositories — VIFERON®. The immunological survey was conducted in dynamics: at the height of the disease and in the convalescence period. The blood was determined indicators of cellular immunity (leukocytes, lymphocytes, CD3+, CD4+, CD8+, CD56+, HLAII+, CD95+, CD1 6+, CD25+), the concentration of IFN-a, IFN-y, IL-4 levels in spontaneous and induced production, in the serum). At milestones children of the main group noted rapid regression of clinical symptoms, normalization of body temperature, reducing intoxication, positive dynamics lymphoproliferative syndrome), a significant reduction in bed-days, no layering respiratory viral infections. Interferon had also expressed a positive impact on the changed parameters of cellular immunity and cytokine links. At the same time, 80% of patients after basic treatment is established the predominance of Th2 type immune response, indicating a high risk of developing chronic course of EBV-mononucleosis.Проведено клинико-иммунологическое обследование 51 ребенка с острым Эпштейна-Барр вирусным мононуклеозом (ЭБВ-мононуклеозом) в возрасте от 1 года до 7 лет. У всех детей диагностирована среднетяжелая форма болезни. В лечении 25 чел. (группа сравнения) использовали базисную терапию (патогенетическую, симптоматическую), лечение 26 чел. (основная группа) включало применение в качестве противовирусного и иммунотропного препарата человеческого рекомбинантно-го интерферона альфа-2b в виде ректальных суппозиториев — ВИФЕРОНА®. Иммунологическое обследование проводилось в динамике: в периоде разгара болезни и в периоде реконвалесценции. В крови определяли показатели клеточного звена иммунитета (лейкоциты, лимфоциты, CD3+, CD4+, CD8+, CD56+, HLAII+, CD95+, CD16+, CD25+), концентрации IFN-a, IFN-y, IL-4линических симптомов (нормализация температуры тела, снижение интоксикации, положительная динамика лимфопролифе-ративного синдрома), существенное сокращение койко-дня, отсутствие наслоения острой респираторной вирусной инфекции. Интерферонотерапия оказала так же выраженное положительное влияние на измененные показатели клеточного и цитокинового звеньев иммунитета. В то же время, у 80% пациентов, получавших базисную терапию, установлено преобладание Th2 типа иммунного ответа, что свидетельствует о высоком риске формирования хронического течения ЭБВ-мононуклеоза

Клинико-иммунологическая оценка эффективности применения рекомбинатного интерферона альфа-2b в терапии детей, больных корью

The aim of the study was to assess the clinical and immunological efficacy of recombinant interferon Alfa-2b. Examined 34 children aged from 1 year to 7 years carrying medium to heavy degree of measles. All patients were not vaccinated against measles. In the treatment of 18 people (Control group) were used only basic therapy (pathogenic, symptomatic). At 16 people (Study group) used a combination therapy (basic + Viferon). As an antiviral agent used and immunotropic preparation of human recombinant interferon alfa-2b in the form of rectal suppositories – Viferon (OOO «Feron», Russia). Immunological patient survey was conducted in the dynamics of the disease – during the height (in 1-6 days the rash) and in convalescence period (10-16 days rash). Indicators of cellular immunity (leukocytes, lymphocytes, CD3 +, CD3 + CD (16 + 56) +, CD3 + CD4 +, CD3 + CD8 +, CD4 + CD8 +, CD3-CD8 +, CD3-CD (16 + 56), CD19 +, CD25 +, CD3 + HLA DR +, CD (16 + 56) + HLA DR +, HLA DR +, CD95 +) were evaluated by flow cytometry. To assess the production of IFN-α and IFN-γ in the samples of peripheral blood were cultured in the CO2 incubator for 18 hours at 37 C and 4% CO2. The supernatants of cell culture were investigated with the purpose of studying spontaneous and induced production of interferon alpha and gamma. The concentrations of interferon α and γ (IFNα, IFNγ) in the blood serum, as well as levels of spontaneous and induced cytokine production data of blood cells of sick children was determined by ELISA. All the children at the peak of the disease found a dramatic inhibition of cellular immunity and the production of cytokines, which is consistent with the concept of «measles anergy» accepted in the scientific literature. The period of convalescence oppression immunity indices remained, but it was less pronounced in the group of children treated with the drug of human recombinant interferon alfa-2b -Viferon. Clinical efficacy of Viferon in the treatment of patients with measles children characterized by rapid positive dynamics of symptoms of acute period (normalization of body temperature, reducing intoxication, catarrhal symptoms and severity of the syndrome exanthema). It was also found reduction in the incidence of complications, reduction in the average bedday and smooth during the period of convalescence later.Цель исследования – оценка клинико-иммунологической эффективности рекомбинантного интерферона альфа-2b. Проведено обследование 34 детей в возрасте от 1 года до 7 лет, переносивших среднетяжелую степень кори. Все пациенты против кори не привитые. В терапии 18 человек (группа сравнения) применяли только базисную терапию (патогенетическая, симптоматическая), у 16 человек (основная группа) применяли комбинированную терапию (базисная + Виферон). В качестве противовирусного и иммунотропного средства использовали препарат человеческого рекомбинантного интерферона альфа-2b в виде ректальных суппозиториев – Виферон (ООО «ФЕРОН», Россия). Иммунологическое обследование пациентов проводили в динамике заболевания – в периоде разгара (на 1–6-е сут высыпания) и в периоде реконвалесценции (на 10–16-е сут высыпания). Показатели клеточного звена иммунитета (лейкоциты, лимфоциты, CD3+, CD3+CD(16+56)+, CD3+CD4+,CD3+CD8+, CD4+CD8+, CD3-CD8+, CD3-CD(16+56), CD19+, CD25+, CD3+HLA DR+, CD(16+56)+ HLA DR+, HLA DR+, CD95+) оценивались методом проточной цитометрии. Для оценки продукции IFN-α и IFN-γ образцы периферической крови культивировали в СО2 инкубаторе в течение 18 ч при 37° С и 4% СО2. Супернатанты клеточной культуры исследовались с целью изучения спонтанной и индуцированной продукции интерферона альфа и гамма. Концентрации IFNα, IFNγ в сыворотке крови, а также уровни спонтанной и индуцированной продукции данных цитокинов клетками крови больных детей определяли иммуноферментным методом. У всех детей в периоде разгара болезни установлено резкое угнетение показателей клеточного иммунитета и продукции цитокинов, что согласуется с принятым в научной литературе понятием «коревая анэргия». В периоде реконвалесценции угнетение показателей иммунитета сохранялось, однако было менее выражено в группе  детей, получавших препарат Виферон. Клиническая эффективность применения Виферона в комплексной терапии больных корью детей характеризовалась быстрой положительной динамикой симптомов острого периода (нормализация температуры тела, снижение интоксикации, выраженности катарального синдрома и синдрома экзантемы). Установлено также снижение частоты развития осложнений, сокращение среднего койко-дня и гладкое течение периода поздней реконвалесценции

Efficiency of viferon therapy in infants with acute respiratory virus infection

The impact of VIFERON therapy on clinical, immunological, and virological characteristics was evaluated in 40 children aged 1 month to 3,5 years with acute respiratory virus infection. Study group patients (n=20) received a treatment cycle of VIFERON® in a daily dose of 1 000 000 IU. Comparison group patients (n=20) had symptomatic treatment only. The investigators revealed IgM and IgG antibodies to cytomegalovirus, Epstein—Barr virus, and human herpesvirus 6 and determined herpesvirus DNA in blood, saliva, and urine and respiratory virus DNA/RNA in nasopharyngeal swabs. Flow cytofluorometry was used to study the quantitative composition of lymphocytes with phenotypes CD3+, CD3+4+, CD3+8+, CD3-16+56+, and CD3+CD16+CD56+. The efficiency of VIFERON® therapy was evaluated comparing the results of examinations of the children before and 7 days after treatment. In the study group, the VIFERON® therapy-induced elimination rate for rhinovirus, metapneumovirus, and influenza virus A accounted for 100% and that for respiratory syncytial virus and adenovirus was 87,5 and 66,7%, respectively. In the comparison group, the elimination rate for rhinovirus accounted for 66,7% and that for respiratory syncytial virus and adenoviruses was 0%. The effiacy of VIFERON® against herpesviruses was lower than that against respiratory viruses although Epstein–Barr virus and human herpesvirus 6 eliminations were significantly more frequently noted in the study group patients. In this group, there was accelerated resolution of inflammation, a more pronounced immunotropic effect, including an antiviral effect, than in the comparison group
