В статье приводится клиническое наблюдение токсического гепатита у 11-летнего ребенка с МВ (генотип F508del/F508del в гене CFTR) и синдромом Жильбера (генотип 7ТА/7ТА в гене UGT1A1), получавшего таргетную терапию ЛП элексакафтор / тезакафтор / ивакафтор + ивакафтор, спровоцированного взаимодействием с другими ЛП – умеренными ингибиторами CYP3A (флуконазол и пирантел), назначенными самостоятельно без консультации врача.</p></sec><sec><title>   Заключение</title><p>   Заключение.
