Its proper diagnosis allows for an adequate therapy and an improvement of the outcomes. The article presents a short literature review with an emphasis on the challenging diagnostic and therapeutic aspects, illustrated by a clinical case. The diagnosis of IgG4-SC is based on a combination of biochemical, radiological and histological signs and symptoms, including elevated levels of serum IgG4, intra- and extrahepatic biliary strictures detected by magnetic resonance cholangiography, and multifocal IgG4-lymphoplasmic infiltrations, sclerosing fibrosis of the bile ducts, seen at morphological assessment. Glucocorticoids (GCS) are the first line agents to achieve remission in patients with IgG4-SC. Most patients respond well to the systemic GCS. However, about 20% of patients (mostly those with extensive sclerotic intra- and/or extrahepatic abnormalities and signs of advanced disease / cirrhosis) show an insufficient or no response from the beginning of the treatment. The clinical case illustrates that timely verification of the IgG4-SC diagnosis may have an important prognostic value. The case history of a 62-year old female patient confirms the difficulties of the early diagnosis of the disease: for a relatively long time, the patient had the diagnosis of primary sclerosing cholangitis. Delay with GCS prescription (the treatment was initiated only at the stage of liver cirrhosis) had led to the lack of clinical efficacy and development of complications, such as relapsing cholangitis with advanced biliary strictures. In patients with suspected primary sclerosing cholangitis, timely differential diagnosis with IgG4-SC is relevant, because early GCS administration can slow the progression of the disease.</p></abstract><trans-abstract xml:lang="ru"><p>Иммуноглобулин G4-ассоциированный склерозирующий  холангит (IgG4-СХ) может имитировать первичный склерозирующий холангит, холангиокарциному, аденокарциному поджелудочной  железы. Своевременная диагностика позволяет  проводить  адекватную  терапию и улучшать прогноз заболевания. В настоящей статье  представлен   краткий  обзор  литературы  с акцентом  на  аспектах, вызывающих диагностические    и    терапевтические    трудности, проиллюстрированные клиническим примером. Диагностика  IgG4-СХ основана  на сочетании   биохимических,   радиологических и   гистологических   признаков,   среди   которых – повышенный уровень  IgG4 в сыворотке крови, внутрипеченочные и внепеченочные билиарные стриктуры, выявляемые при магнитно-резонансной холангиографии, и мультифокальные IgG4-лимфоплазматические инфильтрации, склерозирующий фиброз желчных протоков, определяемые морфологически. Глюкокортикостероиды (ГКС) – препараты  первой  линии для достижения  ремиссии  у пациентов  с IgG4-СХ. Большинство  пациентов  хорошо реагируют на терапию системными ГКС. Однако около 20% больных (чаще это пациенты с выраженными  склерозирующими  внутрипеченочными  и/или внепеченочными изменениями и признаками  продвинутого  заболевания на стадии цирроза  печени) имеют неполный ответ  или  изначально   не  отвечают  на  лечение. Приведенное  клиническое наблюдение наглядно  демонстрирует,  что  своевременная верификация  диагноза IgG4-СХ может иметь важное прогностическое  значение. История болезни  пациентки 62 лет подтверждает  трудности ранней диагностики заболевания: достаточно длительное  время диагнозом пациентки был первичный склерозирующий холангит. Несвоевременное назначение  ГКС  (терапия была назначена уже на стадии цирроза  печени) привело  к отсутствию клинической  эффективности и развитию  осложнений  – рецидивирующему холангиту на фоне  выраженных  билиарных стриктур. Пациентам с подозрением на первичный  склерозирующий  холангит целесообразно  своевременно проводить  дифференциальный диагноз с IgG4-СХ, поскольку раннее назначение  ГКС позволяет  замедлить  прогрессирование заболевания.</p><p> </p></trans-abstract><kwd-group xml:lang="en"><kwd>IgG4-associated sclerosing cholangitis</kwd><kwd>primary sclerosing cholangitis</kwd><kwd>immunoglobulin G4</kwd><kwd>glucocorticoid</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>IgG4-ассоциированный склерозирующий холангит</kwd><kwd>первичный склерозирующий холангит</kwd><kwd>иммуноглобулины G4</kwd><kwd>глюкокортикостероиды</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
