Последствием данного ответа может быть синтез антител к ГИБП, которые способны изменять фармакокинетику и фармакодинамику препарата. Целью данного исследования была оценка содержания циркулирующих антител к препаратам рекомбинантного эритропоэтина (рЭПО) и их взаимосвязи с неэффективностью проводимой терапии у пациентов на хроническом гемодиализе. На базе научно-исследовательского института нефрологии ПСПбГМУ имени акад. И.П.Павлова нами были отобраны 37 пациентов с ХБП 5 стадии, длительное время находящихся на гемодиализе и получающих различные типы препаратов рЭПО. Для сравнительного анализа все пациенты были разделены на две группы: первая группа со сниженным ответом на терапию (СОТ) – 21 пациент; вторая группа – группа с нормальным ответом на терапию (НОТ), 16 пациентов. Иммунологическим контролем послужили образцы крови здоровых доноров, никогда не получавших препараты ЭПО (n = 35). Концентрация антител была измерена с помощью методики дотблоттинга. Верхний порог значений у 35 здоровых доноров крови был определен путем измерения концентрации антител в серии пошаговых разведений (от 1:10 до 1:200) донорских сывороток. Определенный нами верхний порог нормальных значений связывающих антител составил 20,27 мкг/мл (95 CI% ± 0,43). Из 37 пациентов с ХБП, получавших препараты рЭПО, у 20 (54,05%) концентрация антител к рЭПО была выше установленного порога значений. Обнаружена статистически значимая обратная корреляция между концентрацией анти-рЭПО и средними уровнями гемоглобина и эритроцитов за 12 месяцев (r = -0,368, p = 0,025 и r = -0,336, p = 0,042 соответственно). У пациентов группы СОТ концентрация антител к рЭПО и средние дозы рЭПО, применявшиеся в течение 1 года, были достоверно выше по сравнению с группой НОТ (p = 0,0019). Полученные данные указывают на значительную частоту выявления анти-рЭПО и их ассоциацию со снижением терапевтической эффективности препаратов рЭПО.</p><p> </p></abstract><trans-abstract xml:lang="en"><p>Biological preparations (BP) obtained by gene engineering possess a special characteristic called immunogenicity, i.e. propensity of biological drugs to induce an undesired immune response associated with arising anti-drug antibodies. These antibodies can change BP pharmacokinetics and pharmacodynamics, and therapeutical efficacy. A significant proportion of hemodialysis patients with end-stage renal disease treated by recombinant erythropoietin (rEPO) have clinical features of resistance to such therapy. The aim of the study was to investigate whether anti-rEPO antibodies are associated with hemoglobin concentrations (Hb) and red blood cells counts (RBC) in hemodialysis patients, receiving long-term rEPO therapy. This research was performed at the Research Institute of Nephrology at the First St. Petersburg I.Pavlov State Medical University. Thirty-seven hemodialysis patients (pts) with end-stage renal disease and anemia treated with different rEPO formulations were included into the study. The patients were further divided into two groups: those with diminished and normal clinical response to rEPO therapy (DCR, n = 21 vs NCR group, n = 16, respectively). To determine threshold levels of antibodies to rEPO-beta (Roche, Switzerland) we tested blood serum samples of 35 healthy blood donors who never received rEPO in the past. Concentration of antibodies was measured by means of dot-blot method. The threshold antibody concentrations were defined by measurement of anti-rEPO concentrations in 2-fold stepwise dilutions (1:10 to 1:200) of blood sera from 35 healthy donors .The threshold value for rEPO-binding antibodies was 20.27 µg/ml (95 CI%±0.43). Antibodies to rEPO were found in 54 % of serum samples in the patients. Anti-rEPO antibodies concentrations correlated with mean values of hemoglobin and erythrocyte counts over a period of 12-months for the entire group of hemodialysis patients (r = -0.368, p = 0.025 and r = -0.336, p = 0.042 respectively). Concentration of anti-rEPO antibodies, and the mean weekly rEPO dose were significantly higher in DCR group, compared to NCR group (p = 0.0019). In conclusion, higher levels of anti-rEPO binding antibodies seem to be associated with decreased therapeutic response to the clinically applied rEPO formulations.</p><p> </p></trans-abstract><kwd-group xml:lang="ru"><kwd>эритропоэтин</kwd><kwd>анемия</kwd><kwd>иммуногенность</kwd><kwd>антитела</kwd></kwd-group><kwd-group xml:lang="en"><kwd>erythropoietin</kwd><kwd>anemia</kwd><kwd>immunogenicity</kwd><kwd>antibodies</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">Добронравов В.А., Смирнов А.В., Безруких А.М., Быстрова Н.Н., Дроздова Ю.В., Орлова С.А.
