PDE5A-Positive Cancer-Associated Fibroblasts Drive Immune Exclusion in Gastric Cancer — Therapeutic Rationale for Combining PDE5 Inhibition with LAG3 Blockade

Single‑cell and spatial profiling identify a PDE5A+ CAF subset that remodels stroma, activates PI3K/AKT/mTOR–CXCL12 signaling, and recruits exhausted LAG3+ CD8 T cells, promoting immune exclusion in gastric cancer. Vardenafil plus LAG3 blockade restores antitumour immunity in preclinical models, supporting biomarker‑driven combination trials.
Peginterferon Add‑On to siRNA JNJ‑73763989 Yields Deep HBsAg Declines but Not Durable Off‑Therapy Cure in HBeAg‑Positive CHB: Phase 2 REEF‑IT Results

Peginterferon Add‑On to siRNA JNJ‑73763989 Yields Deep HBsAg Declines but Not Durable Off‑Therapy Cure in HBeAg‑Positive CHB: Phase 2 REEF‑IT Results

In the phase 2 REEF‑IT trial, pegylated interferon‑α2a added to siRNA JNJ‑73763989 produced large HBsAg reductions and transient seroclearance in some untreated HBeAg‑positive patients, but no participant reached the prespecified sustained off‑therapy HBsAg loss endpoint at 24 weeks.

Not All ‘Indeterminate’ HBV Is Equal: Specific Indeterminate Types Carry Markedly Higher Long‑Term HCC Risk

A multinational cohort study of 1,986 patients with indeterminate chronic hepatitis B (CHB) shows large differences in long‑term hepatocellular carcinoma (HCC) risk by baseline indeterminate subtype and by phase transition, identifying subgroups that may benefit from earlier antiviral therapy and intensified surveillance.

Immune-related adverse events strongly predict early graft rejection after liver transplant in HCC patients treated with checkpoint inhibitors

A multicentre retrospective cohort found that pretransplant immune-related adverse events (irAEs) markedly increase the risk of early liver allograft rejection after liver transplantation for hepatocellular carcinoma (HCC). IrAEs, short ICI washout, and younger recipient age were independent predictors.

Predicting Early Acute Kidney Injury After Liver Transplantation: A Clinically Useful 48‑Hour Risk Model

A single-center study developed and internally validated a 48‑hour post‑liver transplant AKI risk model using five readily available preoperative and intraoperative variables (HE, alcohol cirrhosis, ALBI ≥ −1.78, operation time ≥560 min, and FFP transfusion). The model showed good discrimination (AUC ≈0.76).

Higher Early IV Fluid Rates Tied to More SIRS but Lower BUN Rise in Acute Pancreatitis: Findings From an International Cohort Presented at ACG 2025

An international prospective cohort found that higher early IV fluid rates were associated with lower odds of BUN rise but higher odds of new or persistent SIRS at 6 and 24 hours after presentation, highlighting confounding issues and the need to individualize resuscitation.

Enhancing Prognostication in Chronic Liver Disease: The Role of Liver Corrected T1 and Magnetic Resonance Elastography in Real-World Clinical Practice

This study highlights the complementary utility of liver corrected T1 (cT1) and magnetic resonance elastography (MRE) for predicting chronic liver disease progression, emphasizing the critical prognostic role of disease activity beyond fibrosis severity, especially in steatotic liver disease.
