Целью настоящего исследования является изучение влияния и прогнозирование  исходных характеристик пациента ХГС 1 генотипа на развитие  лейкопении (ЛП) и нейтропении  (НП). Исследовались  такие факторы, как пол, возраст, индекс массы тела (ИМТ), вирусная нагрузка, генотип интерлейкина 28В (ИЛ-28В), исходный уровень лейкоцитов и нейтрофилов, активность аланинаминотрансферазы (АЛТ), степень фиброза, длительность инфицирования, наличие предшествующей терапии. Абсолютные значения лейкоцитов и нейтрофилов анализировали на 4, 12, 24, 48 неделях терапии, а также через 4, 12, 24 недель после окончания противовирусной терапии (ПВТ) с применением ингибиторов протеазы (ИП) 1 и 2 поколения. Были выявлены прогностические критерии, указывающие на возможное развитие ЛП и НП при применении схем, содержащих интерферон: женский пол, низкая исходная нагрузка, ТТ-генотип ИЛ-28В, исходный уровень лейкоцитов и нейтрофилов ниже 5,7×109/л и 3,4×109/л соответственно. Также были построены математические модели предсказания наступления ЛП и НП, формализованные в виде деревьев принятия решения. Данные модели показали наибольший потенциал для практического использования ввиду наибольшей точности и достоверности.</p></abstract><trans-abstract xml:lang="en"><p>Currently in the Russian Federation or chronic hepatitis C (CHC) are still relevant Interferon-based regimens. The purpose of this study is to investigate the influence of baseline characteristics and prognosis of the patient HCV genotype 1 for the development  of leukopenia (LP) and neutropenia  (NP). We investigated  factors such as sex, age, body mass index (BMI), viral load, genotype  of Interleukin-28 B (IL-28B),  the initial level of leukocytes and neutrophils,  alanine aminotransferase (ALT), fibrosis, duration  of infection, presence  of previous therapy.  Absolute values of leukocytes  and neutrophils  were analyzed on 4, 12, 24, 48 weeks of therapy,  and at 4, 12, 24 weeks after antiviral treatment with protease  inhibitors (PI) 1 and 2 generation. Prognostic criteria were identified, indicating the possible development  of the LP and NP expressed during treatment with interferon: female  gender,  low initial load, TT-genotype of IL-28B, the  initial level of white  blood cells and neutrophils  below 5,7×109/L and 3,4×109/L, respectively. Mathematical  models predicting the onset of LP and NP, formalized in the form of decision trees were also constructed. These models have shown the greatest potential for practical use in view of highest accuracy and reliability.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хронический гепатит С</kwd><kwd>противовирусная терапия</kwd><kwd>1 генотип</kwd><kwd>ингибиторы протеазы 1 и 2 поколения</kwd><kwd>интерферонсодержащие схемы</kwd><kwd>нежелательные  явления</kwd><kwd>лейкопения</kwd><kwd>нейтропения</kwd><kwd>прогнозирование</kwd><kwd>математические  модели</kwd><kwd>деревья  принятия решения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic hepatitis C</kwd><kwd>antiviral therapy</kwd><kwd>genotype  1</kwd><kwd>protease inhibitors 1 and 2 generation</kwd><kwd>interferon-based regimens</kwd><kwd>adverse events</kwd><kwd>leukopenia</kwd><kwd>neutropenia</kwd><kwd>prognosis</kwd><kwd>mathematical models</kwd><kwd>decision trees</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">Абдурахманов Д.Т., Морозов В.Г., Никитин И.Г. и др.
