AIH and PBC

Perceived stigma (PS) adversely impacts psychosocial and disease outcomes in patients with chronic liver diseases (CLD), and those with autoimmune hepatitis (AIH) may be at risk for PS given inaccurate assumptions about the origin of their diagnosis. The aims of the current study are to describe the frequency of PS in patients with AIH, compare rates of PS in AIH to rates of PS in primary biliary cholangitis (PBC) and CLD, and examine demographic correlates of PS. 262 adults with AIH (95% female, Mage  = 51...

Autoimmune liver diseases (AILDs) are complex diseases with unknown causes and immune-mediated pathophysiology. In primary biliary cholangitis (PBC) and autoimmune hepatitis (AIH) disease modifying drugs are available which improve patient quality and quantity of life. In primary sclerosing cholangitis (PSC) no medical therapy is available and the only accepted treatment is liver transplantation (LT). PBC, PSC and AIH possess features that describe the archetype of patients within each disorder. On the other hand, the classical disorders are not homogeneous, and patients within each diagnosis may present with a range of clinical, biochemical, serological, and histological findings...

UNLABELLED: Primary biliary cholangitis (PBC) is a chronic autoimmune cholestatic liver disease. If this disease is not treated, it might lead to fibrosis, cirrhosis, and its associated complications.1 Early recognition of this entity and immediate institution of therapy are the primary prognostic modifiers.2 Anti-nuclear autoantibodies can be used for diagnosis, particularly the anti-gp 210 and anti-Sp100 antibodies. Our aim in this study is to describe the epidemiology, clinical, biochemical, and immunological aspects of patients with PBC, thus, emphasizing the role of those antibodies...

Two patients were incidentally diagnosed with intra-abdominal lymphadenopathy on imaging examinations. Although endoscopic ultrasound-guided fine needle aspiration of these areas of lymphadenopathy was performed, their causes remained undetermined. Neither patients had abnormal hepatic enzyme levels at the time lymphadenopathy was detected, but they developed hepatitis 20 months and five months later, respectively. The laboratory data and/or histopathological findings suggested primary biliary cholangitis/cirrhosis (PBC) and autoimmune hepatitis (AIH), respectively...

We present 3 cases of autoimmune liver disease in human immunodeficiency virus (HIV)-infected patients and describe the different diagnostic and therapeutic approaches used in each case. The first patient was diagnosed with primary biliary cholangitis (PBC) with features of autoimmune hepatitis (AIH), requiring second-line therapy due to incomplete response to ursodeoxycholic acid. The second patient was diagnosed with AIH with features of PBC and had the particular challenges of presenting with advanced liver fibrosis and having a past history of disseminated cytomegalovirus infection...

INTRODUCTION: Standardization of diagnostic criteria of autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC) variant syndrome (AIH-PBC VS) has not been achieved so far and evidence-based recommendations for monitoring and treatment of the disease are still lacking. Our study aimed to assess the prevalence, biochemical, and serological features, as well as the clinical course, of VS. METHODS: We performed a retrospective study including all patients with VS between 1999 and 2020 in four German centers...

BACKGROUND & AIMS: Concurrent fatty liver disease represents an emerging challenge in the care of individuals with autoimmune liver diseases (AILD). Therefore, we aimed to validate the ultrasound-based method of controlled-attenuation parameter (CAP) as a non-invasive tool to detect hepatic steatosis in individuals with AILD. METHODS: The diagnostic performance of CAP to determine biopsy-proven hepatic steatosis (>5%) was assessed in individuals with AILD (autoimmune hepatitis [AIH], primary biliary cholangitis [PBC], primary biliary cholangitis [PSC], or variant syndromes) who underwent liver biopsy at the University Medical Center Hamburg-Eppendorf between 2015-2020 by calculating the area under the receiver operating characteristic (AUROC) curves...

BACKGROUND: Noninvasive methods have been developed to detect fibrosis in many liver diseases due to the limits of liver biopsy. However, previous studies have focused primarily on chronic viral hepatitis and nonalcoholic fatty liver disease. The diagnostic value of transient elastography for autoimmune liver diseases (AILDs) is worth studying. AIM: To compare the diagnostic accuracy of imaging techniques with serum biomarkers of fibrosis in AILD. METHODS: The PubMed, Cochrane Library and EMBASE databases were searched...

BACKGROUND: Patients with autoimmune hepatitis-primary biliary cholangitis (AIH-PBC) overlap syndrome have a worse prognosis compared to AIH or PBC alone and accurately predicting the severity and dynamically monitoring the progression of disease are therefore essential. We aimed to develop a nomogram-based model to predict advanced liver fibrosis in patients with AIH-PBC overlap syndrome. METHODS: A total of 121 patients with AIH-PBC overlap syndrome were retrospectively included and randomly assigned to a development set and a validation set...

This study aimed to evaluate the clinical value of the monocyte to high-density lipoprotein cholesterol ratio (MHR) and alkaline phosphatase-to-platelet ratio (APPR) in the diagnosis and prognosis of primary biliary cholangitis (PBC). Clinical and laboratory data were retrospectively collected and analyzed from 92 PBC patients, 92 patients with autoimmune hepatitis (AIH), 120 patients with chronic hepatitis B (CHB) and 124 healthy controls (HCs). We compared the levels of MHR and APPR among the groups with PBC, AIH, CHB and HCs, and analyzed the correlations between MHR and APPR with laboratory indices including aspartate aminotransferase platelet ratio index, fibrosis index based on 4 factors, and Mayo score in PBC...

There was evidence that pANCA (perinuclear antineutrophil cytoplasmic antibodies) in autoimmune liver diseases react with human beta-tubulin-5 (TBB5). Here we re-evaluate the specificity and clinical relevance of anti-TBB5 antibodies. Patients with untreated autoimmune hepatitis (AIH; n=53), AIH under immunosuppressive therapy (AIH-IS; n=125), primary sclerosing cholangitis (PSC; n=40), primary biliary cholangitis (PBC; n=250), non-autoimmune liver diseases (n=158), inflammatory bowel diseases (IBD; n=30), and healthy individuals (n=62) were tested by enzyme linked immunosorbent assay (ELISA) for IgG- and IgA-antibodies against recombinant human TBB5...

INTRODUCTION: Scurfy mice have a complete deficiency of functional regulatory T cells (Treg) due to a frameshift mutation in the Foxp3 gene. The impaired immune homeostasis results in a lethal lymphoproliferative disorder affecting multiple organs, including the liver. The autoimmune pathology in scurfy mice is in part accompanied by autoantibodies such as antinuclear antibodies (ANA). ANA are serological hallmarks of several autoimmune disorders including autoimmune liver diseases (AILD)...

BACKGROUND: Epidemiological studies have indicated a potential link between the gut microbiome and autoimmune liver disease (AILD) such as autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC). The relationship between the gut microbiome and autoimmune liver disease is still uncertain due to confounding variables. In our study, we aim to shed light on this relationship by employing a two-sample Mendelian randomization approach. METHODS: We conducted a two-sample Mendelian randomization (MR) study using the R package "TwoSampleMR"...

BACKGROUND AND AIMS: Patients with some chronic liver diseases have increased risk of diabetes. Whether this is also the case for patients with autoimmune liver diseases is unknown. The study aimed to calculate risk and worldwide prevalence of diabetes in patients with autoimmune hepatitis (AIH), primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC). METHODS: We performed a case-control study using data from the United Kingdom Biobank (UKB) and compared frequency of type 1 diabetes (T1D) and type 2 diabetes (T2D) in AIH and PBC with age-, sex-, BMI- and ethnicity-matched controls...

Autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC) are autoimmune liver diseases that target the liver and have a wide spectrum of presentation. A global overview of quantitative variations on the salivary proteome in presence of these two pathologies is investigated in this study. The acid-insoluble salivary fraction of AIH and PBC patients, and healthy controls (HCs), was analyzed using a gel-based bottom-up proteomic approach combined with a robust machine learning statistical analysis of the dataset...

BACKGROUND: (Auto)immune mediated and cholestatic liver disease (AILD) includes autoimmune hepatitis (AIH), primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC). Especially AIH is characterized by the presence of autoantibodies and elevated serum immunoglobulins. In rheumatoid arthritis, autoantibodies against post-translational modifications (PTMs) such as citrullination (Cit) and carbamylation (CarP) are used as diagnostic and prognostic markers, respectively. We studied the presence of six anti-PTM antibodies in patients with the three AILDs and non-AILD...

BACKGROUND AIMS: Primary sclerosing cholangitis (PSC) is a chronic progressive liver disease characterized by infiltration of intrahepatic tissue-resident memory CD8+ T cells (TRM). Itaconate has demonstrated therapeutic potential in modulating inflammation. An unmet need for PSC is the reduction of biliary inflammation, and we hypothesized that itaconate may directly modulate pathogenic TRM. METHODS: The numbers of intrahepatic CD103+ TRM were evaluated by immunofluorescence in PSC (n = 32) and serum levels of itaconate in PSC (n = 64), primary biliary cholangitis (PBC) (n = 60), autoimmune hepatitis (AIH) (n = 49), and healthy controls (n = 109) were determined by LC-MS/MS...

BACKGROUND: Hepatocellular carcinoma (HCC) is a primary tumor of the liver. The majority of HCCs are associated most frequently with chronic B or C viral hepatitis, alcohol intake or aflatoxin exposure. Cirrhosis is a strong risk factor associated with HCC. The causes of liver cirrhosis are chronic viral hepatitis, alcohol intake, metabolic diseases (NAFLD), hemocromathosis, alfa 1 antitrypsisn deficiency. All aetiologic forms of cirrhosis are at risk to be complicated by HCC development, but the risk is higher for patients diagnosed with chronic viral hepatitis...

OBJECTIVES: The diagnosis of autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and AIH-PBC overlap syndrome (OS) relies on their histologic features and clinical findings. In this study, we aimed to identify specific morphologic features of these diseases and evaluate their clinical correlation. METHODS: We included initial biopsies from untreated patients with AIH (n = 14), PBC (n = 10), and OS (n = 7). Histologic features of the portal tract, portal-lobular interface, and hepatic lobule, fibrosis, as well as clinical data including serology, autoantibodies, treatment, and prognosis were reviewed and analyzed...
