Autoimmune liver diseases (AILD) involve dysregulated CD4 T cell responses against liver self-antigens, but how these autoreactive T cells relate to liver tissue pathology remains unclear. Here we perform single-cell transcriptomic and T cell receptor analyses of circulating, self-antigen-specific CD4 T cells from patients with AILD and identify a subset of liver-autoreactive CD4 T cells with a distinct B-helper transcriptional profile characterized by PD-1, TIGIT and HLA-DR expression. These cells share clonal relationships with expanded intrahepatic T cells and exhibit transcriptional signatures overlapping with tissue-resident T cells in chronically inflamed environments.

Article Synopsis
  • A systematic review and meta-analysis were conducted to evaluate the effectiveness and safety of naltrexone as a treatment for amphetamine-type stimulant use disorder (ATSUD) using data from several medical databases.
  • Five randomized placebo-controlled trials involving 419 participants were analyzed, showing no significant difference in outcomes such as reductions in stimulant use, treatment retention, or cravings between naltrexone and placebo groups.
  • The study concluded that there is insufficient evidence to support the use of naltrexone alone for treating ATSUD, highlighting the need for more research to find effective pharmacotherapies alongside psychosocial treatments.

The Hierarchical Taxonomy of Psychopathology (HiTOP) is a dimensional framework for psychopathology advanced by a consortium of nosologists. In the HiTOP system, psychopathology is grouped hierarchically from super-spectra, spectra, and subfactors at the upper levels to homogeneous symptom components and maladaptive traits and their constituent symptoms, and maladaptive behaviors at the lower levels. HiTOP has the potential to improve clinical outcomes by planning treatment based on symptom severity rather than heterogeneous diagnoses, targeting treatment across different levels of the hierarchy, and assessing distress and impairment separately from the observed symptom profile.

  • Relapse after stopping immunosuppression treatment is common in Autoimmune Hepatitis (AIH) patients, and there's a need for better non-invasive biomarkers to predict this risk.
  • The study analyzed blood samples from 58 active AIH patients, 56 in remission, and 31 with NASH, focusing on the levels of activated T cell subsets and the cytokine BAFF.
  • Results showed that increased frequencies of certain activated T cells and high BAFF levels in remission patients were strongly linked to a higher chance of relapse after treatment withdrawal, suggesting these could serve as useful biomarkers for monitoring AIH.

Background And Aims: Baveno VII consensus suggests that screening endoscopy can be spared in patients with compensated cirrhosis when spleen stiffness measurement (SSM) by vibration-controlled transient elastography (VCTE) is ≤40 kPa as they have a low probability of high-risk varices (HRV). Conversely, screening endoscopy is required in all patients with porto-sinusoidal vascular disorder (PSVD). This study aimed to evaluate the performance of SSM-VCTE to rule out HRV in patients with PSVD and signs of portal hypertension.
