RESUMO
INTRODUCTION AND OBJECTIVES: Autoimmune liver diseases (AILDs) are rare and require precise evaluation, which is often challenging for medical providers. Chatbots are innovative solutions to assist healthcare professionals in clinical management. In our study, ten liver specialists systematically evaluated four chatbots to determine their utility as clinical decision support tools in the field of AILDs. MATERIALS AND METHODS: We constructed a 56-question questionnaire focusing on AILD evaluation, diagnosis, and management of Autoimmune Hepatitis (AIH), Primary Biliary Cholangitis (PBC), and Primary Sclerosing Cholangitis (PSC). Four chatbots -ChatGPT 3.5, Claude, Microsoft Copilot, and Google Bard- were presented with the questions in their free tiers in December 2023. Responses underwent critical evaluation by ten liver specialists using a standardized 1 to 10 Likert scale. The analysis included mean scores, the number of highest-rated replies, and the identification of common shortcomings in chatbots performance. RESULTS: Among the assessed chatbots, specialists rated Claude highest with a mean score of 7.37 (SD = 1.91), followed by ChatGPT (7.17, SD = 1.89), Microsoft Copilot (6.63, SD = 2.10), and Google Bard (6.52, SD = 2.27). Claude also excelled with 27 best-rated replies, outperforming ChatGPT (20), while Microsoft Copilot and Google Bard lagged with only 6 and 9, respectively. Common deficiencies included listing details over specific advice, limited dosing options, inaccuracies for pregnant patients, insufficient recent data, over-reliance on CT and MRI imaging, and inadequate discussion regarding off-label use and fibrates in PBC treatment. Notably, internet access for Microsoft Copilot and Google Bard did not enhance precision compared to pre-trained models. CONCLUSIONS: Chatbots hold promise in AILD support, but our study underscores key areas for improvement. Refinement is needed in providing specific advice, accuracy, and focused up-to-date information. Addressing these shortcomings is essential for enhancing the utility of chatbots in AILD management, guiding future development, and ensuring their effectiveness as clinical decision-support tools.
RESUMO
Acute hepatitis presenting with blood eosinophilia are scarcely reported. Different clinical courses of autoimmune hepatitis (AIH) have been associated with acute hepatitis with eosinophilia, however it is still unclear if the latter is a common manifestation of different autoimmune diseases, part of a similar spectrum of eosinophil-associated liver injury or even a trigger to AIH. We report a case of a 32 years old woman who presented with subacute hepatitis, peripheral eosinophilia, hypergammaglobulinemia and liver biopsy suggestive of AIH. The role of eosinophils in autoimmune liver diseases deserves further studies in order to clarify its physiopathology aspects.

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.

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.

INTRODUCTION AND OBJECTIVES: It has been proposed that non-invasive methods may replace liver biopsy for the diagnosis of tissue damage in patients with autoimmune liver disease (ALD). The aim of this study was to determine diagnostic performance and degree of concordance between the APRI index and liver biopsy for diagnosing cirrhosis in these patients. MATERIAL AND METHODS: In a cohort of patients with ALD, the value of the APRI index and liver biopsy results were determined according to the METAVIR score. The AUC and the degree of concordance between an APRI value >2 and a METAVIR score of F4 were evaluated as markers of liver cirrhosis, through a kappa statistic. RESULTS: In total, 70 patients (age 51 ± 13 years) were included. The most common autoimmune liver diseases were primary biliary cirrhosis (PBC) (40%), autoimmune hepatitis (AIH) (24.3%) and AIH-PBC overlap syndrome (32.9%). Cirrhosis was confirmed by biopsy in 16 patients (22.9%). 15 patients (21.4%) had an APRI index >2 (Cirrhosis) and only six met both criteria. The AUC of the APRI was 0.77 (95% CI 0.65-0.88). The degree of concordance between the tests was low for an APRI cut-off point >2 (kappa 0.213; 95% CI 0.094-0.332), as well as for cut-off points >1.5, >1 and >0.5 (kappa 0.213, 0.255, 0.257, respectively) CONCLUSION: Our results suggest that there is little concordance between APRI and liver biopsy for the diagnosis of cirrhosis in patients with ALD. It should therefore not be used as a single diagnostic method to determine cirrhosis.

INTRODUCTION AND OBJECTIVES: Patient-reported outcomes (PROs) are important for comprehensive assessment of chronic liver disease (CLD). Latin America and the Caribbean have a high burden of CLD, but PROs are lacking. We assessed health-related quality of life (HRQL) in Cuban patients with compensated CLD. MATERIALS AND METHODS: A cross sectional study performed of adult patients with a diagnosis of chronic viral infection B and C (HBV, HCV), non-alcoholic fatty liver diseases (NAFLD) and autoimmune liver diseases (AILD) including autoimmune hepatitis (AIH), primary biliary cholangitis (PBC) and overlap syndrome (AIH+PBC). PROs were collected using: Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Work Productivity and Activity-Specific Health Problem (WPAI: SHP), and the Chronic Liver Disease Questionnaire (CLDQ)-disease-specific. RESULTS: 543 patients enrolled, n=91 (HBV), n=188 (HCV), n=221 (NAFLD), n=43 (AILD). Of those with AILD, 22 had AIH, 14 PBC, and 7 overlap AIH/PBC. Mean age was 53.5 years, 64.1% female, 69.2% white, and 58.0% employed. Patients with HCV and AILD had more severe liver disease. A significant impairment in PROs was observed in HCV group whereas the AILD patients had more activity impairment. CLDQ-HRQL scores were significantly lower for patients with NAFLD and AILD compared to HBV. Male gender and exercising ≥90min/week predicted better HRQL. The strongest independent predictors of HRQL impairment were fatigue, abdominal pain, anxiety, and depression (p<0.05). CONCLUSIONS: HRQL for Cuban patients with compensated CLD differs according to the CLD etiology. Patients with HCV and AILD had the worst PRO scores most likely related to severe underlying liver disease and/or extrahepatic manifestations.

Systemic lupus erythematosus (SLE) is a multi-organic autoimmune disease with a wide variety of clinical manifestations. However, hepatic dysfunction is not included in the diagnostic criteria for the disease and has not been recognized properly. The spectrum of hepatic involvement described in these patients ranges from abnormalities in liver function tests (LFTs) to fulminant hepatic failure. Usually, abnormalities in LFTs are only mild and transient, have a hepatocellular pattern and are not related to SLE but rather are mostly drug related. The most frequent finding on liver biopsy is steatosis (non-alcoholic fatty liver disease). Patients do not frequently progress to advanced chronic liver disease, and their outcome is favourable. Those who develop cirrhosis have traditional risk factors, such as other non-SLE-related conditions. In this work, we aim to review hepatic manifestations in patients with SLE, as well as the diagnostic and therapeutic approaches used for different liver diseases in these patients.

Introducción: El espectro del compromiso hepático en la enfermedad celíaca es muy amplio e incluye hepatopatías virales y autoinmunes. Objetivo: Caracterizar el comportamiento de los marcadores serológicos de hepatopatías virales y autoinmunes en pacientes celíacos adultos atendidos en el Instituto de Gastroenterología. Materiales y Métodos: Se realizó un estudio observacional descriptivo transversal en el período comprendido entre marzo de 2016 y marzo 2017 en 43 pacientes adultos celíacos atendidos en el Instituto de Gastroenterología de La Habana. A todos, previo consentimiento informado se les realizaron estudios bioquímicos y serológicos para identificar infección por virus de hepatitis B, C y respuesta inmune humoral frente a autoanticuerpos hepáticos y sistémicos. Para el análisis estadístico se emplearon distribuciones de frecuencia y para la comparación entre los grupos se utilizó la probabilidad exacta de Fisher. Se consideró significativo una p < 0,05. Resultados: El 58,1 por ciento de los pacientes presentó hipofosfatasemia y 14 por ciento hipertransaminasemia, sin coincidencias entre los casos registrados. El 100 por ciento de los celíacos fue negativo para el virus de hepatitis C. La positividad de autoanticuerpos hepáticos se registró entre 2,3 por ciento y 14 por ciento de los pacientes evaluados. Existió asociación significativa entre hipertransaminasemia y la presencia de anticuerpos séricos contra la transglutaminasa tisular. Conclusiones: La expresión de marcadores de autoinmunidad hepática en los pacientes celíacos evaluados es frecuente, no así la presencia de marcadores de hepatopatías virales(AU)
Introduction: The spectrum of hepatic involvement in celiac disease is very broad and includes viral and autoimmune hepatopathies. Objective: To characterize the behavior of serologic markers of viral and autoimmune hepatopathies in adult celiac patients treated at the Institute of Gastroenterology. Materials and Methods: A cross-sectional observational study was conducted in 43 adult celiac patients treated at the Institute of Gastroenterology of Havana from March 2016 to March 2017. Prior informed consent, biochemical and serologic studies were carried out in all cases, in order to identify hepatitis B and C virus infections and humoral immune response to liver and systemic autoantibodies. Frequency distributions were used for statistical analysis, and Fisher's exact test was used for the comparison between groups. Results: 58.1 percent of the patients presented hypophosphatasemia and hypertransaminasemia in 14 percent, with no coincidence between the cases recorded. The 100 percent of the celiac patients were negative for hepatitis C virus. The positivity of liver autoantibodies was recorded between 2,3 percent and 14 percent of the patients evaluated. There was a significant association between hypertransaminasemia and the presence of serum antibodies against tissue transglutaminase. Conclusions: The expression markers of liver autoimmunity in celiac patients was frequent, but not the presence of markers of viral hepatopathy(AU)

Primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) are both autoimmune cholestatic liver disease and the association of these two conditions in the same patient is very rare. We report the case of a female patient presenting with a cholestatic liver disease and a panel of autoantibodies specific for PBC, including antibodies to mitochondrial E2-pyruvate dehydrogenase, gp-210 and Sp-100. Beside these findings, the liver biopsy revealed concentric fibrosis of small biliary ducts and the magnetic resonance cholangiography presented no abnormal findings. Diagnosis of small duct PSC/PBC overlapping was done. No description of this association was found in the literature. Clinical and serological features of this unusual finding are discussed.
