Background & Aims: Biliary abnormalities in autoimmune hepatitis (AIH) and interface hepatitis in primary biliary cholangitis (PBC) occur frequently, and misinterpretation may lead to therapeutic mistakes with a negative impact on patients. This study investigates the use of a deep learning (DL)-based pipeline for the diagnosis of AIH and PBC to aid differential diagnosis.

Methods: We conducted a multicenter study across six European referral centers, and built a library of digitized liver biopsy slides dating from 1997 to 2023.

Background & Aims: Noninvasive tests (NITs) for ruling-out clinical significant portal hypertension (CSPH) and high-risk varices (HRVs) in patients with primary biliary cholangitis (PBC) and compensated advanced chronic liver disease (cACLD) are lacking. We evaluated NITs in these patients and the influence of cholestasis on their performance.

Methods: Consecutive patients from the "Italian PBC registry" and 2 United Kingdom large-volume PBC referral centers with upper endoscopy within 6 months from biochemical evaluation and transient elastography were included.

Purpose: In cases of perihilar focal liver lesions, distinguishing between benign strictures and malignancies is critical to prevent unnecessary surgery. Although the use of contrast-enhanced CT or MRI in combination with clinical and laboratory findings can aid in diagnosis, histologic examination is often necessary. Histologic specimens can be obtained through various techniques, including ERCP-guided brush cytology or intraductal biopsy, cholangioscopy-directed biopsy or endoscopic ultrasound (EUS).

Article Synopsis
  • The study explores the use of AI chatbots, specifically ChatGPT-4, as a tool for personalized counseling for Autoimmune Hepatitis (AIH) patients, assessing their performance on twelve specific patient inquiries.
  • Key metrics evaluated include accuracy, completeness, comprehensiveness, and safety of the chatbot’s responses, rated by a group of 11 experts using various scales.
  • Results reveal that while the chatbot provides good comprehensive information, its reliability is questionable, especially in diagnosing inquiries, indicating a need for further research before integrating it into clinical settings.

Porto-sinusoidal vascular disorder (PSVD) encompasses a group of vascular disorders characterized by lesions of the portal venules and sinusoids with clinical manifestations ranging from non-specific abnormalities in serum liver enzymes to clinically overt portal hypertension and related complications. Several reports have documented cases of PSVD in patients with systemic autoimmune conditions, such as systemic lupus erythematosus, systemic sclerosis, and rheumatoid arthritis. It is of note that these diseases share specific pathophysiological features with PSVD, including endothelial dysfunction, vascular inflammation, and molecular signatures.
