Drug-induced bile duct injury: progress and challenges / 中华肝脏病杂志

Drug-induced bile duct injury is a specific kind of drug-induced liver injury that has two main pathological types, namely ductopenia, or vanishing bile duct syndrome, and secondary sclerosing cholangitis. However, in recent years, the reports of new drugs that cause bile duct injury have been constantly increasing, and these drugs have different clinicopathological features and a novel pathogenesis. Therefore, this paper summarizes and analyzes the progress and challenges in the etiology, pathogenesis, diagnosis and treatment, and other aspects of drug-induced bile duct injury.

Excerpt from the 2022 American Association for the Study of Liver Diseases clinical practice guideline: management of primary sclerosing cholangitis and cholangiocarcinoma / 中华肝脏病杂志

What are the new contents of the guideline since 2010?A.Patients with primary and non-primary sclerosing cholangitis (PSC) are included in these guidelines for the diagnosis and management of cholangiocarcinoma.B.Define "related stricture" as any biliary or hepatic duct stricture accompanied by the signs or symptoms of obstructive cholestasis and/or bacterial cholangitis.C.Patients who have had an inconclusive report from MRI and cholangiopancreatography should be reexamined by high-quality MRI/cholangiopancreatography for diagnostic purposes. Endoscopic retrograde cholangiopancreatography should be avoided for the diagnosis of PSC.D. Patients with PSC and unknown inflammatory bowel disease (IBD) should undergo diagnostic colonoscopic histological sampling, with follow-up examination every five years until IBD is detected.E. PSC patients with IBD should begin colon cancer monitoring at 15 years of age.F. Individual incidence rates should be interpreted with caution when using the new clinical risk tool for PSC for risk stratification.G. All patients with PSC should be considered for clinical trials; however, if ursodeoxycholic acid (13-23 mg/kg/day) is well tolerated and after 12 months of treatment, alkaline phosphatase (γ- Glutamyltransferase in children) and/or symptoms are significantly improved, it can be considered to continue to be used.H. Endoscopic retrograde cholangiopancreatography with cholangiocytology brushing and fluorescence in situ hybridization analysis should be performed on all patients suspected of having hilar or distal cholangiocarcinoma.I.Patients with PSC and recurrent cholangitis are now included in the new unified network organ sharing policy for the end-stage liver disease model standard.J. Liver transplantation is recommended after neoadjuvant therapy for patients with unresectable hilar cholangiocarcinoma with diameter < 3 cm or combined with PSC and no intrahepatic (extrahepatic) metastases.

Colelitíase sintomática como apresentação de colangite esclerosante primária na infância - série de casos e revisão de literatura / Symptomatic cholelithiasis as the presentation of pediatric primary sclerosing cholangitis - case series and literature review

ABSTRACT BACKGROUND: Primary sclerosing cholangitis (PSC) is a rare hepatobiliary disorder, whose etiology remains not fully elucidated. Given how rare PSC is in childhood, until the recent publication of a multicenter international collaboration, even data on its characteristics and natural history were scarce. Symptomatic cholelithiasis has not been previously reported as the presentation of PSC. OBJECTIVE: The aim of this study was the diagnosis of PSC following the initial unusual presentation with symptomatic cholelithiasis, that followed an atypical clinical course that could not be explained by cholelithiasis alone. A literature review was also conducted. METHODS: We conducted a retrospective chart review of three patients, who were diagnosed and/or followed at the Clinics Hospital, University of Campinas - Sao Paulo/ Brazil, between 2014 and 2020. Data analyzed included gender, age of presentation, past medical history, imaging findings, laboratory results, endoscopic evaluation, response to medical therapy and follow-up. RESULTS: Age at time of presentation with cholelithiasis varied from 10 to 12 years. In two of the cases reported, a more subacute onset of symptoms preceded the episode of cholelithiasis. Two patients were managed with cholecystectomy, not followed by any surgical complications, one patient was managed conservatively. Percutaneous liver biopsy was performed in all three cases, showing histological findings compatible with PSC. Associated inflammatory bowel disease (IBD) was not seen in any of the patients. The patients have been followed for a mean time of 3.4 years. CONCLUSION: PSC and cholelithiasis are both rare in the pediatric population. This study reports on symptomatic cholelithiasis as a presentation of PSC and raises the importance of suspecting an underlying hepatobiliary disorder in children with cholelithiasis without any known predisposing factors and/or that follow an atypical clinical course for cholelithiasis alone.

RESUMO CONTEXTO: A colangite esclerosante primária (CEP) é uma doença hepatobiliar rara, cuja etiologia ainda não está totalmente elucidada. Dada a raridade do CEP na infância, até a recente publicação de uma colaboração multicêntrica internacional, mesmo dados sobre suas características e história natural eram escassos. A colelitíase sintomática não foi relatada anteriormente como a apresentação inicial de CEP na infância. OBJETIVO: O objetivo deste estudo foi o diagnóstico de CEP após a apresentação inicial incomum com colelitíase sintomática, que seguiu um curso clínico atípico que não poderia ser explicado apenas pela colelitíase. Também foi realizada uma revisão da literatura. MÉTODOS: Foi realizada uma revisão retrospectiva dos prontuários de três pacientes, que foram diagnosticados e/ou acompanhados no Hospital das Clínicas da Universidade Estadual de Campinas - São Paulo / Brasil, entre 2014 e 2020. Os dados analisados incluíram sexo, idade de apresentação, história médica pregressa, achados de imagem, resultados laboratoriais, avaliação endoscópica, resposta à terapia médica e acompanhamento. RESULTADOS: A idade no momento da apresentação da colelitíase variou de 10 a 12 anos. Em dois dos casos relatados, um início mais subagudo dos sintomas precedeu o episódio de colelitíase. Dois pacientes foram tratados com colecistectomia, não seguida de qualquer complicação cirúrgica, e um paciente foi tratado de forma conservadora. Biópsia hepática percutânea foi realizada em todos os três casos, mostrando achados histológicos compatíveis com CEP. Doença inflamatória intestinal associada não foi observada em nenhum dos pacientes. Os pacientes foram acompanhados por um tempo médio de 3,4 anos. CONCLUSÃO: CEP e colelitíase são raras na população pediátrica. Este estudo relata a colelitíase sintomática como uma apresentação de CEP e levanta a importância da suspeita de doença hepatobiliar subjacente em crianças com colelitíase sem quaisquer fatores predisponentes conhecidos e/ou que seguem um curso clínico atípico.

Hepatopatías autoinmunes. Hallazgos clínicos y de laboratorio en pacientes de un hospital de referencia nacional / Autoimmune liver diseases. Clinical and laboratory findings in patients in a national reference hospital

Introducción. Las enfermedades autoinmunes del hígado son un grupo de patologías caracterizadas por una respuesta autoinmune contra los hepatocitos y/o el epitelio biliar. Sus manifestaciones clínicas son variadas, con alteraciones en las pruebas de función hepática y presencia de autoanticuerpos. Metodología. Estudio observacional descriptivo con 101 pacientes atendidos en el Hospital Universitario de La Samaritana de Bogotá D.C., entre enero a diciembre de 2019, con los diagnósticos de hepatitis autoinmune, colangitis biliar primaria, colangitis esclerosante primaria y síndrome de sobreposición. Se evaluaron los parámetros clínicos y de laboratorio, con el fin de caracterizar su frecuencia en estas patologías, debido a la importancia de un diagnóstico precoz. Resultados. Se encontraron 54 casos de hepatitis autoinmune, 19 casos de colangitis biliar primaria, 4 casos de colangitis esclerosante primaria y 24 casos de síndrome de sobreposición. El 81% fueron mujeres y la edad promedio fue de 55 años. El 39% de los pacientes tenían cirrosis. En general, los resultados se ajustaron a lo descrito internacionalmente, como es el predominio en mujeres y la comorbilidad autoinmune. Conclusión. Los hallazgos indican que cualquier alteración del perfil bioquímico hepático debe ser considerado, y se debe descartar la presencia de hepatopatías autoinmunes para diagnosticarlas de manera precoz, evitando que lleguen a cirrosis y sus complicaciones, con la necesidad de un trasplante hepático como única alternativa terapéutica.

Introduction. Autoimmune liver diseases are a group of pathologies characterized by an autoimmune response against hepatocytes and/or the biliary epithelium. Their clinical manifestations are varied, with alterations in liver function tests and the presence of autoantibodies. Methodology. Descriptive study with 101 patients who attended at the Hospital Universitario de La Samaritana in Bogota D.C., between January and December 2019, with the diagnoses of autoimmune hepatitis, primary biliary cholangitis, primary sclerosing cholangitis and overlap syndrome. Clinical and laboratory parameters were evaluated in order to characterize their frequency in these pathologies, due to the importance of an early diagnosis. Results. There were 54 cases of autoimmune hepatitis, 19 cases of primary biliary cholangitis, 4 cases of primary sclerosing cholangitis, and 24 cases of overlap syndrome. Of all patients, 81% were women, the average age was 55 years, and 39% had cirrhosis. In general, the findings were consistent with what has been described worldwide, such as a higher prevalence in women and autoimmune comorbidity. Conclusion. The findings indicate that any alteration in the liver biochemical profile should be considered to rule out an autoimmune liver disease for an early diagnosis, avoiding the possibility of cirrhosis and its complications, with the need for a liver transplant as the only therapeutic alternative.

Colangite esclerosante primária em crianças e adolescentes / Primary sclerosing cholangitis in children and adolescents

ABSTRACT BACKGROUND: Primary sclerosing cholangitis is a rare disease, but its prevalence has been underestimated in children and adolescents due to broad variation in clinical presentation as well as diagnostic challenges in this life period. OBJECTIVE: To evaluate children and adolescents with primary sclerosing cholangitis and to describe their clinical, laboratorial, histopathological, and cholangiography conditions. METHODS: This is an observational descriptive research that took place from 2005 to 2016 and included all the patients seen in the Outpatient Unit for Pediatric Hepatology of Hospital das Clinicas of UFMG who had been diagnosed with primary sclerosing cholangitis before the age of 18. Diagnosis was established through clinical, laboratory, radiographic and/or histopathologic criteria. Other chronic liver diseases were excluded, as well as secondary causes of cholangitis. Data analysis used statistic resources in SPSS software. Variables were expressed as averages, standard deviation, absolute frequency, and percentage. RESULTS: Twenty-one patients fulfilled criteria to be included in the research sample. Male patients predominated (3.2:1) and average age at diagnosis was 6.7±3.9 years. Five (23.8%) patients had associated inflammatory bowel disease, four had ulcerative colitis and one indeterminate colitis. Signs and symptoms vary and are usually discrete at presentation. The most frequent symptom was abdominal pain (47.6%) followed less frequently by jaundice (28.6%) and itching (14.3%). The reason for medical investigation was asymptomatic or oligosymptomatic enzyme alterations in 33.3% of patients. All patients presented increased hepatic enzymes: aminotransferases, gamma glutamyl transferase, and alkaline phosphatase. Twenty patients had alterations compatible to primary sclerosing cholangitis in their cholangiography exam; one patient had no alterations at magnetic resonance cholangiography, but presented histopathologic alterations that were compatible to small duct cholangitis. Hepatic fibrosis was present in 60% of 15 patients who were biopsied upon admission; cirrhosis being present in four (26.7%) patients. A total of 28.5% of patients had unfavorable outcomes, including two (9.5%) deaths and four (19%) transplants. CONCLUSION: Primary sclerosing cholangitis is a rare disease in childhood and adolescence and its initial diagnosis may be delayed or overlooked due to asymptomatic or unspecific clinical manifestations. The association with inflammatory bowel disease is common. Prognosis may be unfavorable as the disease progresses and hepatic transplant is the definitive treatment.

RESUMO CONTEXTO: A colangite esclerosante primária é uma doença rara, mas sua prevalência tem sido subestimada em crianças e adolescentes, tanto pela variedade de apresentação clínica quanto pela dificuldade diagnóstica neste período. OBJETIVO: Avaliar crianças e adolescentes com colangite esclerosante primária descrevendo seu quadro clínico, laboratorial, histopatológico e colangiográfico. MÉTODOS: Trata-se de um estudo descritivo observacional, de 2005 a 2016, de todos os pacientes atendidos no Ambulatório de Hepatologia Pediátrica do Hospital das Clínicas da UFMG, com o diagnóstico de colangite esclerosante primária até a idade de 18 anos. O diagnóstico foi estabelecido segundo os critérios clínicos, laboratoriais, radiológicos e/ou histopatológicos. Foi realizada investigação para exclusão de outras doenças hepáticas crônicas e causas secundárias de colangite. A análise dos dados foi efetuada com os recursos estatísticos do software SPSS. As variáveis foram expressas por meio de médias, desvio-padrão, frequência absoluta e porcentagem. RESULTADOS: Vinte e um pacientes preencheram os critérios de inclusão. Houve predomínio no sexo masculino (3,2:1). A média de idade ao diagnóstico foi 6,7±3,9 anos. Cinco (23,8%) pacientes apresentavam doença inflamatória intestinal associada, sendo quatro casos de colite ulcerativa e um de colite indeterminada. Na apresentação, os sinais e sintomas são variados, em geral discretos. O sintoma mais frequente foi dor abdominal (47,6%), seguido menos frequentemente por icterícia (28,6%) e prurido (14,3%). Em 33,3% dos pacientes, o motivo de início da investigação foi alteração de enzimas em pacientes assintomáticos ou oligossintomáticos. Todos os pacientes exibiam aumento das enzimas hepáticas: aminotransferases, gama glutamiltransferase e fosfatase alcalina. Vinte pacientes apresentavam alterações em exame colangiográfico, compatíveis com colangite esclerosante primária; um paciente não apresentava alterações na colangiorressonância, mas apresentava alterações histopatológicas compatíveis com colangite de pequenos ductos. Fibrose hepática já estava presente em 60% dos 15 pacientes com biópsia à admissão; com cirrose estabelecida em quatro pacientes. 28,5% dos pacientes tiveram evolução desfavorável, com dois (9,5%) óbitos e quatro (19%) pacientes transplantados. CONCLUSÃO: Colangite esclerosante primária é uma doença rara na criança e no adolescente, cujo diagnóstico inicial pode ser atrasado ou passar despercebido, principalmente por apresentar manifestações clínicas inespecíficas ou cursar de forma assintomática. É frequente a associação com doença inflamatória intestinal. O prognóstico pode ser reservado com o avançar da doença, sendo o transplante hepático o tratamento definitivo.

Sclerosing Cholangitis: Clinicopathologic Features, Imaging Spectrum, and Systemic Approach to Differential Diagnosis

Sclerosing cholangitis is a spectrum of chronic progressive cholestatic liver disease characterized by inflammation, fibrosis, and stricture of the bile ducts, which can be classified as primary and secondary sclerosing cholangitis. Primary sclerosing cholangitis is a chronic progressive liver disease of unknown cause. On the other hand, secondary sclerosing cholangitis has identifiable causes that include immunoglobulin G4-related sclerosing disease, recurrent pyogenic cholangitis, ischemic cholangitis, acquired immunodeficiency syndrome-related cholangitis, and eosinophilic cholangitis. In this review, we suggest a systemic approach to the differential diagnosis of sclerosing cholangitis based on the clinical and laboratory findings, as well as the typical imaging features on computed tomography and magnetic resonance (MR) imaging with MR cholangiography. Familiarity with various etiologies of sclerosing cholangitis and awareness of their typical clinical and imaging findings are essential for an accurate diagnosis and appropriate management.

Dolor abdominal e ictericia recurrente como manifestación clínica en un niño con colangitis escleronsante primaria / Abdominal pain and recurrent jaundice as demonstration clinic in a child with primary sclerosing cholangitis

La colangitis esclerosante primaria es una enfermedad hepatobiliar progresiva caracterizada por una inflamación crónica con fibrosis periductal de los conductos biliares intra y extrahepáticos que producen constricciones y ectasia generalizadas del tracto biliar. Se presenta el caso de un escolar masculino de 12 años de edad, quien inicio enfermedad actual a partir de los 5 años de edad cuando presentó dolor abdominal recurrente localizado en epigastrio y mesogastrio, leve a moderada intensidad, tipo cólico. A partir de los 8 años de edad se anexó tinte ictérico en piel y mucosa, con orinas coloreadas en forma intermitente. A los 10 años de edad, el 16/06/2008, el dolor abdominal aumenta en intensidad acompañado de nauseas, recibió tratamiento con sucralfato y ranitidina sin mejoría por lo que el 19/06/2008 se hospitalizó. Se le realizó exámenes de laboratorio que reportó elevación de las transaminasas, fosfatasa alcalina y gamma glutamil transpeptidasa. Tomografía abdominal signos sugestivos de colangitis por lo que se realizó serología para algunos virus hepatotropos, colangioresonancia y posteriormente biopsia hepática corroborándose el diagnóstico de colangitis esclerosante primaria. Aunque es una enfermedad colestásica frecuentes en el adulto debe ser tomada en cuenta en niños para hacer un diagnóstico precoz y posterior seguimiento

Primary sclerosing cholangitis is a disease progressive hepatobiliary characterized by chronic inflammation with bile duct intra periductal fibrosis and extrahepatic that produce widespread biliary tract constrictions and ectasia. The case of a male school of 12 years of age who start current illness from 5 years of age when he presented recurrent abdominal pain located in the epigastrium and mesogastrio, mild to moderate intensity, cramping occurs. From the age of 8 was annexed on skin and mucosa, icteric dye with urine colored intermittently. To 10 years of age, 16/06/2008, abdominal pain increases in intensity accompanied of nausea, he received treatment with sucralfate and ranitidine without improvement for what 06 19, 2008 hospitalized. Laboratory tests which reported elevation of transaminases, alkaline phosphatase and gamma-glutamyl transpeptidase was carried out. Abdominal CT signs suggestive of cholangitis by what took place some virus serology hepatotropic, Magnetic Resonance Cholangiography and then liver biopsy corroborating the diagnosis of primary sclerosing cholangitis. Although is a disease common in the adult cholestatic should be taken into account in children to make an early diagnosis and subsequent follow-up

Colangiopatía asociada a SIDA: cuando la sola imagen no basta / AIDS cholangiopathy: when images in isolation are not enough

In HIV-infected patients, liver and biliary tract may be affected by different entities, such as AIDS-cholangiopathy, which is usually associated with CD4+T lymphocytes count below 100 cells/mm³ along with non-specific symptoms. Although imaging studies play a major diagnostic role they should always be evaluated according to patients clinical context. While ultrasound and CT scans provide relevant diagnostic information, specialized studies such as MRI and MRCP have become increasingly valuable due to their ability to demonstrate parietal as well as stenotic biliary changes. Despite ERCP remains the gold-standard for diagnosis of AIDS-related cholangiopathy, currently it is usually reserved to clearly exclude the presence of malignancy, or as a specific invasive therapeutic procedure, when indicated.

En pacientes infectados con VIH, el hígado y las vías biliares pueden presentar compromiso de distinta índole. Dentro de éstos, la colangiopatía asociada al SIDA se presenta con una sintomatología más bien inespecífica y habitualmente con recuentos de linfocitos T CD4 <100/mm³. En este escenario, si bien los estudios de imagen juegan un rol muy relevante, éstos siempre deben ser evaluados en relación al contexto clínico del paciente. Si bien la ecografía y la TC aportan valiosa información en el diagnóstico, en la actualidad la resonancia magnética de abdomen combinada con colangioresonancia tienen gran utilidad, por ser capaces de demostrar tanto las alteraciones parietales, como los cambios morfológicos estenóticos biliares de esta patología. Si bien la ERCP aún conserva su valor de gold standard para el diagnóstico, actualmente la tendencia se dirige a reservarla para el descarte de neoplasias, en casos dudosos o como procedimiento terapéutico invasivo específico, cuando sea indicado.

Biliary Cast Formation with Sclerosing Cholangitis in Critically Ill Patient: Case Report and Literature Review

Sclerosing cholangitis in critically ill patients (SC-CIP) is a rare condition that is not familiar to many radiologists. In addition, the associated imaging findings have not been described in the radiological literature. We report a case of biliary cast formation with SC-CIP and describe the radiological findings of CT, magnetic resonance cholangiopancreatography (MRCP), and endoscopic retrograde cholangiography (ERC). A diagnosis of SC-CIP should be considered in intensive care unit (ICU) patients with persistent cholestasis during or after a primary illness. The typical CT, MRCP and ERC findings include new biliary casts in the intrahepatic duct with multiple irregular strictures, dilatations, and relative sparing of the common bile duct.

Colangite esclerosante primária (CEP) / Primary sclerosing cholangitis (PSC)

A CEP é uma doença hepática colestática crônica caracterizada por estenoses da árvore biliar intra e extra-hepática, que pode causar cirrose e colangiocarcinoma em 10% a 30% dos pacientes. Comumente associa-se com a doença inflamatória intestinal e pode causar morte por insuficiência hepática. A CEP é considerada doença hepática imunomediada, multifatorial, multigenética de causa desconhecida. CPRE e colangiopancreatografia ressonância são recomendadas para o diagnóstico de CEP. O clássico achado em -contas de rosário- é resultado de áreas multifocais de estenoses de ductos biliares intra ou extra-hepáticas, intercalados com segmentos normais ou dilatados. A citologia de ductos biliares com estenoses e os dados histológicos de material obtidos por punção possibilitam o diagnóstico de colangiocarcinoma. Não há tratamento eficaz para a CEP. O AuDC pode reduzir as elevações de enzimas hepáticas, seu efeito sobre a histologia hepática e o prognóstico são inconclusivos. O transplante hepático continua sendo o único tratamento comprovado a longo prazo para a CEP, porém com recorrência em 20% a 40% dos pacientes.

Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterized by strictures of the biliary tree intrahepatic and extrahepatic that may cause cirrhosis and cholangiocarcinoma in 10%-30% of patients. It is commonly associated with intestinal inflammatory disease and ultimately leading to death by liver failure. PSC is considered to be an immune-mediated liver disease of multifactorial and multigenectic origin of unknown etiology. ERCP and magnetic resonance cholangiopancreatography are recommend for diagnosing PSC. The classical -beaded- cholangiographic findings in PSC result from multifocal areas of stricturing of intra or extrahepatic bile ducts with the intervening segments of normal or dilated ducts. Cytology from bile ducts strictures and histopathological findings in bile ducts are indicated to diagnosis of cholangiocarcinoma. There is no efficiency therapy for PSC. ursodeoxycholic acid may improve liver enzymes, its effects on liver histology and prognosis are inconclusive. Repeat endoscopic dilatations and prosthesis may be benefic in some cases. Liver transplantation remains the only proven long-term treatment for PSC but recurrence of PSC in the liver graft affets as many as 20% - 40% of patients.

[Crohn's disease, primary sclerosing cholangitis and antiphospholipid ayndrome: an uncommon association]

Inflammatory bowel diseases are frequently associated with extra-intestinal manifestations and other autoimmune disorders. Association between primary sclerosing cholangitis and Crohn's disease is established. However, the association of antiphospholipid syndrome with Crohns disease was reported in the literature only in the form of isolated case reports. To report a Tunisian case of association of Crohn's disease, primary scierosing cholangitis and antiphospholipid syndrome. We report the case of a patient presenting a colonic Crohn's disease associated with primary scierosing cholangitis and antiphospholipid syndrome. Scierosing cholangitis was diagnosed basing on disturbances of the hepatic biochemical tests. Antiphospholipid syndrome was revealed by a venous thrombosis of the lower limbs. Although the anticardiolipin antibodies were frequently found during the course of primary scierosing cholangitis, the association with antiphospholipid syndrome is exceptionally described. In the same way, triple association of primary sclerosing cholangitis, Crohn's disease and antiphospholipid syndrome was not brought back in the literature

A Case of Sclerosing Cholangitis Showing Response to Prednisolone / 대한소화기학회지

Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterized by progressive fibrosis and destruction of intra- and extrahepatic bile ducts resulting in hepatic failure and death. Only the liver transplantation is the possible treatment for patients to survive. There has been a few reports that steroid is an effective treatment in autoimmune variant sclerosing cholangitis, which is thought to be a familial diseases with different etiology, and steroid responsive biliary strictures be named as immunoglobulin G4 (IgG4)-associated cholangitis (IAC). There is no reliable data regarding effective steroid treatment in autoimmue variant sclerosing cholangitis in Korea. We report a case of 32-year-old male with sclerosing cholangitis, who was diagnosed by endoscopic retrograde cholangiopancreatography (ERCP) and liver biopsy, showing favorable response to prednisolone therapy.

Hepatite auto-imune e colangite esclerosante primária: síndrome de superposição / Autoimmune hepatitis and primary sclerosing cholangitis: overlap syndrome

Raramente, pacientes apresentam concomitância de achados clínicos, bioquímicas e histológicos de hepatite auto-imune e de colangite esclerasante primária. Essa situação denomina-se síndrome de superposição, que, com freqüência, representa um desafio diagnóstico. Apresenta-se o caso de um paciente masculino de 17 anos, que consultou por icterícia e sintomas constitucionais. Apresentava elevação das aminotransferases, da gamaglobulina e auto-anticorpos circulantes, preenchendo critérios definitivos para hepatite auto-imune. A biópsia hepática demonstrou achados característicos de hepatite auto-imune, como infiltrado rico em plasmócitos, formação rosetóide de hepatócitos e hepatite de interface intensa, mas, também, alterações típicas de colangite esclerosante primária, como a fibrose concêntrica periductal do tipo "casca de cebola". A colangiopancreatografia retrógrada endoscópica foi altamente sugestiva de colangite esclerosante primária. Estabelecido o diagnóstico de síndrome de superposição, rescreveram-se corticosteróides, azatioprina e ácido ursodeoxicólico. Houve excelente resposta clínica e laboratorial. Conclusão: Esta apresentação visa a alertar o gastroenterologista para tal doença, proporcionando, assim, quando de seu diagnóstico, uma proposta terapêutica mais eficaz.

Comparison of Clinical Findings between Autoimmune Pancreatitis with Bile Duct Involvement and Primary Sclerosing Cholangitis / 대한소화기학회지

BACKGOUND/AIMS: The involvement of bile ducts is frequently reported in autoimmune pancreatitis (AIP), which seem to have similar features to primary sclerosing cholangitis (PSC). Recent systematic comparative studies about these diseases are rare in Korea. METHODS: We retrospectively analyzed 26 patients with AIP with bile duct involvement and 30 patients with classic PSC who were diagnosed during the last decade. RESULTS: The mean age of patients was significantly higher in AIP than PSC at the time of diagnosis. There was a preponderance of men in both group, which was more prominent in AIP. The most common symptom in patients with AIP was jaundice, but PSC patients usually visited hospitals due to incidentally detected abnormal liver function tests. Most (26/31) of AIP had bile duct involvement. All of these patients showed narrowing of intrapancreatic common bile ducts and one patient exhibited hilar involvement as well. About 80% of PSC had both intra- and extrahepatic ducts involvement, and the characteristic features involve multifocal strictures. AIP patients showed improvement with steroid treatment, however, most PSC patients showed clinical deterioration. CONCLUSIONS: The clinical and cholangiographic findings of patients with AIP and PSC have many different characteristics. Therefore, further study of two diseases is required for the proper diagnosis and management.
