RESUMEN
Spiny keratoderma is a rare dermatological manifestation that occurs sporadically or hereditarily. These are millimetric hyperkeratotic lesions on the palms and/or soles, usually asymptomatic. Histopathologically, they consist of well-defined columns of parakeratosis on a thinned stratum corneum. Sporadic cases can be associated with chronic diseases or neoplasms. We present a case of palmar spiny keratoderma in a man in the seventh decade of life with cirrhosis due to primary sclerosing cholangitis, and hepatocellular carcinoma. He had remission of the skin lesions two months after performing a liver transplant. This behavior favors the interpretation of spiny keratoderma as a paraneoplastic manifestation of hepatocellular carcinoma. We have not found previous reports of spiny keratoderma from Argentina. We review the literature on this entity.
La queratodermia espinosa palmar es una manifestación dermatológica infrecuente que se presenta de forma esporádica o hereditaria. Se trata de lesiones hiperqueratósicas milimétricas en palmas y/o plantas, habitualmente asintomáticas. Histopatológicamente consisten en columnas de paraqueratosis bien delimitadas sobre un estrato córneo adelgazado. Los casos esporádicos se pueden asociar a enfermedades crónicas o neoplasias. Presentamos un caso de queratodermia espinosa palmar en un hombre en la séptima década de la vida con cirrosis secundaria a colangitis esclerosante primaria y hepatocarcinoma. Presentó remisión de las lesiones cutáneas a los dos meses de realizarse un trasplante hepático. Este comportamiento favorece la interpretación de la queratodermia espinosa como manifestación paraneoplásica del hepatocarcinoma. No hemos encontrado informes previos de queratodermia espinosa en Argentina. Realizamos una revisión de la literatura sobre esta entidad.

INTRODUCTION AND OBJECTIVES: Autoimmune liver diseases (AILDs): autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC) have different survival outcomes after liver transplant (LT). Outcomes are influenced by factors including disease burden, medical comorbidities, and socioeconomic variables. MATERIALS AND METHODS: Using the United Network for Organ Sharing database (UNOS), we identified 13,702 patients with AILDs listed for LT between 2002 and 2021. Outcomes of interest were waitlist removal, post-LT patient survival, and post- LT graft survival. A stepwise multivariate analysis was performed adjusting for transplant recipient gender, race, diabetes mellitus, model for end-stage liver disease (MELD) score, and additional social determinants including the presence of education, reliance on public insurance, working for income, and U.S. citizenship status. RESULTS: Lack of college education and having public insurance increased the risk of waitlist removal (HR, 1.13; 95 % CI, 1.05-1.23, and HR, 1.09; 95 % CI, 1.00-1.18; respectively), and negatively influenced post-LT patient survival (HR, 1.16; 95 % CI, 1.06-1.26, and HR, 1.15; 95 % CI, 1.06-1.25; respectively) and graft survival (HR, 1.13; 95 % CI, 1.05-1.23, and HR, 1.15; 95 % CI, 1.06-1.25; respectively). Not working for income proved to have the greatest detrimental impact on both patient survival (HR, 1.41; 95 % CI, 1.24-1.6) and graft survival (HR, 1.21; 95 % CI, 1.09-1.35). CONCLUSIONS: Our study highlights that lack of college education and public insurance have a detrimental impact on waitlist mortality, patient survival, and graft survival. Not working for income negatively affects post-LT survival outcomes. Not having U.S. citizenship does not affect survival outcomes in AILDs patients.

BACKGROUND: The prevalence of primary sclerosing cholangitis (PSC) in the general population has not yet been clearly established. The management of PSC should focus on delaying the progression of the disease and restraining its complications. The only curative therapy for the disease remains liver transplantation (LT). PSC is currently the fifth most common indication for LT and corresponds to 5% of all LT indications in adults. AIMS: Our objective is to evaluate the indications and outcomes of PSC patients undergoing LT in three liver transplantation centers in southern Brazil - Hospital Santa Isabel in Blumenau, Santa Catarina state, and Hospital das Clínicas and Hospital Nossa Senhora das Graças, in Curitiba, Parana state). METHODS: This is a longitudinal observational study of patients with PSC who underwent LT in three major Brazilian medical centers. Electronic medical records and study protocols of all patients subjected to LT from January 2011 to December 2021 were retrospectively reviewed. RESULTS: Of the 1,362 transplants performed in the three medical centers, 37 were due to PSC. Recurrence of PSC occurred in three patients (8.1%) in 3.0±2.4 years (range, 1-4 years). The 1-year and 5-year survival rates after the first LT were 83.8 and 80.6%, respectively. The 1-year and 5-year graft survival rates were, respectively, 83.8 and 74.8%. CONCLUSIONS: Our experience with LT in patients with PSC demonstrated good patient and graft survival results. Most deaths were due to common factors in patients undergoing LT.

BACKGROUND: Liver transplantation represents the best therapeutic modality in end-stage chronic liver disease, severe acute hepatitis, and selected cases of liver tumors. AIMS: To describe a double retransplant in a male patient diagnosed with Crohn's disease and complicated with primary sclerosing cholangitis, severe portal hypertension, and cholangiocarcinoma diagnosed in the transplanted liver. METHODS: A 48-year-old male patient diagnosed with Crohn's disease 25 years ago, complicated with primary sclerosing cholangitis and severe portal hypertension. He underwent a liver transplantation in 2018 due to secondary biliary cirrhosis. In 2021, a primary sclerosing cholangitis recurrence was diagnosed and a liver retransplantation was indicated. Recipient's hepatectomy was very difficult by reason of complex portal vein thrombosis requiring extensive thromboendovenectomy. Intraoperative ultrasound with liver doppler evaluation was performed. Two suspicious nodules were incidentally diagnosed in the donor's liver and immediately removed for anatomopathological evaluation. RESULTS: After pathological confirmation of carcinoma, probable cholangiocarcinoma, at frozen section, the patient was re-listed as national priority and a new liver transplantation was performed within 24 hours. The patient was discharged after 2 weeks. CONCLUSIONS: The screening for neoplasms in donated organs should be part of our strict daily diagnostic arsenal. Moreover, we argue that, for the benefit of an adequate diagnosis and the feasibility of a safer procedure, the adoption of imaging tests routine for the liver donor is essential, allowing a reduction of the costs and some potential risks of liver transplant procedure.

Since the spread of the first cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection much progress has been made in understanding the disease process. However, we are still facing the complications of coronavirus disease 19 (COVID-19). Multiple sequelae may appear as a consequence of acute infection. This set of entities called post-COVID-19 syndrome involves a wide variety of new, recurrent or persistent symptoms grouped together as a consequence of the acute disease process. One of those that has attracted the most attention is the liver and bile duct involvement called post-COVID-19 cholangiopathy. This is characterized by elevation of liver markers such as alkaline phosphatase, bilirubin and transaminases as well as alterations in the bile ducts in imaging studies. Thus, a narrative review of the cases reported until the end of 2021 was carried out. From the findings found, we concluded that patients who have had COVID-19 or during the process have required hospitalization should remain under follow-up for at least 6 months by a multidisciplinary team.

RESUMO RACIONAL: O transplante de fígado representa a melhor modalidade terapêutica na doença hepática crônica terminal, hepatite aguda grave e casos selecionados de tumores hepáticos. OBJETIVOS: Descrever um retransplante duplo em paciente do sexo masculino, diagnosticado com doença de Crohn e complicado com colangite esclerosante primária, hipertensão portal grave e colangiocarcinoma diagnosticado no fígado transplantado. MÉTODOS: Paciente do sexo masculino, 48 anos, diagnosticado com doença de Crohn há 25 anos e complicado com colangite esclerosante primária e hipertensão portal grave. Foi submetido a um transplante de fígado em 2018 devido a cirrose biliar secundária. Em 2021, foi diagnosticada recidiva de colangite esclerosante primária e indicado retransplante hepático. A hepatectomia do receptor foi de alta complexidade devido à trombose complexa da veia porta, exigindo extensa tromboendovenectomia. Foi realizada ultrassonografia intraoperatória com doppler hepático. Dois nódulos suspeitos foram diagnosticados incidentalmente no fígado do doador e imediatamente removidos para avaliação anatomopatológica. RESULTADOS: Após confirmação patológica de carcinoma, provável colangiocarcinoma, pela congelação, o paciente foi relistado como prioridade nacional, e novo transplante hepático foi realizado em 24 horas. O paciente teve alta após 2 semanas. CONCLUSÕES: O rastreamento de neoplasias em órgãos doados deve fazer parte de nosso estrito arsenal diagnóstico diário. Além disso, defendemos que, em benefício de um diagnóstico correto e da viabilidade de um procedimento mais seguro, a adoção de uma rotina de exames de imagem é essencial em doadores hepáticos, permitindo a redução dos custos e alguns riscos potenciais do procedimento de transplante hepático.

BACKGROUND The incidence of abnormal liver function, mainly aspartate aminotransferase and alanine aminotransferase elevations, in patients with COVID-19 is not uncommon, but persistent liver damage after the acute phase of the disease is uncommon and has been recently recognized as a new entity named post-COVID-19 cholangiopathy. CASE REPORT We report a clinical case with progressive cholestatic disease following severe COVID-19. AST and ALT peaked at hospital admission and while its serum concentration went down, bilirubin and cholestatic liver enzymes started to increase, reaching the maximum at day 122. Magnetic resonance imaging (MRI) revealed a diffuse irregularity of intra- and extrahepatic bile ducts, with multiple focal strictures alternating with mild focal dilations of the biliary tree, suggesting a sclerosing cholangiopathy. A transjugular liver biopsy showed a prominent bile ductular reaction, cholangiocyte injury, inflammatory infiltrate rich in neutrophils, biliary infarctions, marked cholestasis, and portal fibrosis, suggesting the diagnosis of post-Covid-19 secondary sclerosing cholangitis. The patient evolved with a continuous deterioration of liver functions, but liver transplantation was not performed due to his poor clinical condition. CONCLUSIONS Post-COVID-19 SSC is a severe disease with no effective clinical treatment and has liver transplantation as the only treatment for a few selected patients.

Cholestasis, which is impaired bile flow from the liver into the intestine, can be caused by cholangitis and/or bile duct obstruction. Cholangitis can arise from bacterial infections and cholelithiasis, however, immune-mediated cholangitis in primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) is characterized by a strong immune response targeting the biliary epithelial cells (BECs). Persistent biliary inflammation further represents a risk for biliary neoplasia, cholangiocarcinoma (CCA) by driving chronic cellular stress in the BECs. Currently, immune-mediated cholangitis is considered a Th1-Th17-dominant disease, however, the presence of Th2-related mast cells (MCs) in tissue samples from PBC, PSC and CCA patients has been described, showing that these MCs are active players in these diseases. Here, we reviewed and discussed experimental and clinical data supporting a pro-fibrotic role for MCs in immune-mediated cholangitis as well as their participation in supporting tumor growth acting as angiogenesis promoters. Thus, although MCs have classically been identified as downstream effectors of Th2 responses in allergies and parasitic infections, evidence suggests that these MCs are relevant players in biliary inflammation and neoplasia. The availability of strategies to prevent MCs' activation represents a therapeutic opportunity in biliary diseases.

Los niveles de bilirrubina sérica normal en el adulto varían entre 0,3 mg/dL y 1,2 mg/dL, y su valor está determinado por la tasa de captación hepática, conjugación y excreción. La ictericia se hace evidente cuando los niveles de bilirrubina sérica se elevan por encima de 2,5 mg/dL a 3 mg/dL, siendo un indicador de enfermedad subyacente. La bilis es producida por los hepatocitos y fluye desde los canalículos, canales de Hering, conductos biliares intrahepáticos, conductos hepáticos derechos e izquierdos hasta llegar al duodeno. A nivel histopatológico, cualquier entidad que lleve a la acumulación intrahepática de bilis por disfunción hepatocelular u obstrucción biliar genera colestasis, que se observa en la biopsia hepática como la acumulación de tapones de color marrón verdoso de pigmento biliar en los hepatocitos, y secundariamente se observan los canalículos dilatados. Las causas de colestasis intrahepática son diversas e incluyen enfermedades como colangitis biliar primaria, colangitis esclerosante primaria, hepatitis autoinmune, hepatitis virales y toxicidad medicamentosa. Esta revisión tiene como objetivo analizar algunos tipos de hiperbilirrubinemia, resaltando sus características histopatológicas.
Normal serum bilirubin levels in adults range from 0.3 mg/dL to 1.2 mg/dL, and its value is determined by the rate of hepatic uptake, conjugation, and excretion. Jaundice becomes apparent when serum bilirubin levels rise above 2.5 mg/dL to 3.5 mg/dL and is an indicator of underlying disease. Bile is produced by hepatocytes and flows from the canaliculi, Hering's canals, intrahepatic bile ducts, and right and left hepatic ducts to the duodenum. Pathologically, any condition that leadsto intrahepatic accumulation of bile due to hepatocellular dysfunction or biliary obstruction, generates cholestasis, which is observed in liver biopsy as the accumulation of greenish-brown deposits of bile pigment in hepatocytes, with dilated canaliculi. The causes of intrahepatic cholestasis are diverse and include diseases such as primary biliary cholangitis and primary sclerosing cholangitis, autoimmune hepatitis, viral hepatitis, and drug toxicity. This review aims to analyze some types of hyperbilirubinemia, highlighting their histopathological characteristics.

La colangitis esclerosante secundaria es una enfermedad poco prevalente, de etiología multifactorial y con una fisiopatología progresiva, caracterizada por obstrucción biliar y fibrosis. Entre las múltiples causas se destacan las siguientes: inmunomediada por IgG4, isquémica, infecciosa y relacionada a medicamentos. En el contexto de la pandemia por SARS-CoV-2, se han reportado algunas series de casos que determinan una asociación entre estas dos entidades. Se presenta el caso de una mujer en la octava década de la vida con infección por SARS-CoV-2 grave, que cursó con ictericia progresiva, perfil hepático con patrón colestásico, y hallazgos imagenológicos de colangitis esclerosante con vía biliar desestructurada de manera difusa, microcálculos y barro biliar. Se diagnosticó colangitis esclerosante secundaria a SARS-CoV-2 y se dio manejo con ácido ursodesoxicólico.
Secondary sclerosing cholangitis is a rare disease of multifactorial etiology with a progressive pathophysiology, characterized by biliary obstruction and fibrosis. Multiple causes include: IgG4-immunemediated, ischemic, infectious and drug-induced. In the context of the SARS-CoV-2 pandemic, some case series have been reported that determine an association between these two entities. We present the case of a woman in her eighth decade with severe SARS-CoV-2 infection that presented with progressive jaundice, liver profile with cholestatic pattern, and imaging findings of sclerosing cholangitis with obliterated bile ducts, microlithiasis and biliary sludge. Sclerosing cholangitis secondary to SARS-CoV-2 was diagnosed and the patient was treated with ursodeoxycholic acid.

Background: Primary sclerosing cholangitis (PSC) is associated with a broad phenotypic spectrum in different populations from diverse ethnic and racial backgrounds. This study aimed to describe the clinical characteristics and outcomes of PSC in a multicenter cohort of patients from Brazil. Methods: Data from the Brazilian Cholestasis Study Group were retrospectively reviewed to assess demographic information and clinical characteristics of PSC, as well as the outcomes, such as transplantation-free survival. Results: This cohort included 210 patients. After excluding 33 (15.7%) patients with PSC and overlap syndrome of autoimmune hepatitis, 177 (97 males, median age 33 (21-42) years) with clear-cut PSC were eligible for this study. Most of the patients (n = 139, 78.5%) were symptomatic, and 104 (58.7%) had advanced PSC at the time of diagnosis. Concurrent inflammatory bowel disease was observed in 78 (58.6%) of the investigated patients (n = 133), and most of them had ulcerative colitis (n = 61, 78.2%). The 1- and 5-year survival free of liver transplantation or death were 92.3 ± 2.1% and 66.9 ± 4.2%, respectively, and baseline advanced PSC, pruritus, and elevated bilirubin levels were independent risk factors for the composite adverse outcome. Females were significantly older and had lower bilirubin levels than males at baseline, but survival was not associated with sex. Approximately 12.4% (n = 22) of patients with PSC died, and 32.8% (n = 58) underwent liver transplantation at a median follow-up time of 5.3 and 3.2 years. Conclusion: Multiethnic Brazilian PSC patients exhibited a less pronounced male predominance and a lower frequency of inflammatory bowel disease than Caucasians. Adverse outcomes were more frequent, probably due to advanced disease at baseline.

OBJECTIVES: To evaluate the prevalence and clinical significance of autoantibodies in children with overweight and obesity with nonalcoholic fatty liver (NAFL) and nonalcoholic steatohepatitis (NASH) compared with those with autoimmune liver disease (ALD). STUDY DESIGN: This was a retrospective, cross-sectional study of children with a biopsy-proven diagnosis of NAFL, NASH, autoimmune hepatitis (AIH), or primary sclerosing cholangitis (PSC) and a body mass index (BMI) >85th percentile treated between 2007 and 2016. RESULTS: A total of 181 patients were identified, including 31 (17%) with NAFL, 121 (67%) with NASH, 12 (6.6%) with ALD (AIH, PSC, or overlap), and 17 (9.4%) with combined ALD and NAFLD. Antinuclear antibody (ANA), anti-actin antibody, and anti-liver kidney microsomal (LKM) antibody were positive in 16.1%, 13.8%, and 0%, respectively, of the patients with NAFL and in 32.8%, 15.5%, and 0%, respectively, of those with NASH. Total immunoglobulin G (IgG) was elevated in 27.3% of the patients with NAFL and in 47.7% of those with NASH, but in 100% of those with ALD. The positive predictive value of LKM was 100% for ALD but only 29% for ANA and 46% for anti-actin antibody. CONCLUSIONS: False-positive rates of autoantibodies were higher in pediatric patients with overweight and obesity with NAFLD compared with the general adult population. Positive LKM had the highest specificity and positive predictive value, and elevated IgG level had the highest sensitivity for ALD. The presence of autoantibodies does not signal more severe NAFLD in children. BMI >98th percentile seems to be an important breakpoint above which ALD is less likely.

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.

OBJECTIVE: To describe the characteristics and clinical course of children and young persons with inflammatory bowel disease (IBD) and sclerosing cholangitis (SC). STUDY DESIGN: Retrospective analysis of clinical characteristics, management, and outcome of two separate cohorts of children and young persons with IBD-SC managed in a tertiary pediatric gastroenterology center and in a tertiary pediatric hepatology center in the UK. RESULTS: Eighty-two pediatric patients (31% female) with IBD-SC and a mean age at diagnosis of 11.9 ± 2.8 years were followed up for a mean of 6.8 ± 3.3 years. The most common type of IBD was ulcerative colitis (55%), followed by unclassified IBD (30%) and Crohn's disease (15%). Autoimmune SC (ASC) was diagnosed in 72%, and small duct SC was diagnosed in 28%. Complication-free and native liver survival were 96% and 100%, respectively, at 5 years after diagnosis and 75% and 88%, respectively, at 10 years after diagnosis. Patients in the gastroenterology center, who were diagnosed with liver disease sooner after diagnosis of IBD compared with the hepatology center cohort (mean, 2.7 ± 6.1 months vs 9.3 ± 19.4 months; P = .03), did not develop liver-related complications during follow-up. CONCLUSIONS: Our data suggest that children with IBD-SC have better clinical outcomes than have been reported previously, particularly if diagnosed early. We recommend prompt assessment for SC, including liver biopsy and biliary imaging, when liver function abnormalities are detected in a children diagnosed with IBD.

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.

Targeted therapies with MAPK inhibitors have proven to modulate the clinical manifestations of patients with Langerhans cell histiocytosis (LCH). We explored the presence of BRAFV600E mutation in our cohort of patients with LCH and cholestasis, sclerosing cholangitis, or liver fibrosis that presented resistance to chemotherapy. The BRAFV600E mutation was detected either in the diagnosis (skin and bone) or liver biopsy in our cohort of 13 patients. Thus, we observed a high incidence of BRAFV600E mutation in 100% either in diagnostic biopsy (skin and bone) or liver biopsy in patients with progressive liver disease, sequela, or liver transplant requirement.

OBJECTIVES: To determine the frequency of the antineutrophil cytoplasmic antibodies (ANCA), antiproteinase-3 and antimyeloperoxidase, in primary sclerosing cholangitis (PSC) with or without inflammatory bowel disease (IBD+ or IBD-) and in different types of autoimmune hepatitis (AIH). Additionally, to verify the agreement between ANCA patterns by indirect immunofluorescence and their antigenic specificities by ELISA. METHODS: For this study, 249 patients were enrolled (42 PSC/IBD+; 33 PSC/IBD-; 31 AIH type-1; 30 AIH type-2; 31 AIH type-3; 52 primary biliary cirrhosis; 30 healthy controls) whose serum samples were tested for ANCA autoantibodies. RESULTS: There were fewer female subjects in the PSC/IBD- group (p=0.034). Atypical perinuclear-ANCA was detected more frequently in PSC/IBD+ patients than in PSC/IBD- patients (p=0.005), and was significantly more frequent in type-1 (p<0.001) and type-3 AIH (p=0.012) than in type-2 AIH. Proteinase-3-ANCA was detected in 25 samples (only one with cytoplasmic-ANCA pattern), and more frequently in PSC/IBD+ than in PSC/IBD- patients (p=0.025). Myeloperoxidase-ANCA was identified in eight samples (none with the perinuclear-ANCA pattern). Among the 62 reactive samples for atypical perinuclear-ANCA, 13 had antigenic specific reactions for proteinase-3 and myeloperoxidase. CONCLUSIONS: PSC/IBD+ differed from PSC/IBD- in terms of sex and proteinase 3-ANCA and atypical perinuclear-ANCA reactivity, the latter of which was more frequently detected in type-1 and type-3 AIH than in type-2 AIH. There was no agreement between ANCA patterns and antigenic specificities in IBD and autoimmune liver diseases, which reinforces the need for proteinase-3 and myeloperoxidase antibody testing.
