International Hepatology

The European Association for the Study of the Liver (EASL) Annual Meeting was successfully held in Milan, Italy, from June 5 to 8, 2024. During the conference, four research posters from Professor Wei Lu 's team at the Hepatobiliary Tumor Department of Tianjin Medical University Cancer Institute and Hospital were presented. These studies cover the fields of liver cancer, cholangiocarcinoma, and liver cirrhosis. This report provides an overview of their findings for our readers.

Acute-on-chronic liver failure (ACLF) is a complex syndrome characterized by acute deterioration of liver function in patients with chronic liver disease, accompanied by high mortality rates due to liver and extrahepatic organ failure. The short-term mortality rate of medical comprehensive treatment for ACLF can reach 50% to 90%. Given the high mortality and complex pathogenesis, research and treatment strategies for ACLF are particularly important. At the 2024 European Association for the Study of the Liver (EASL) Annual Meeting, Professor Hai Li from Renji Hospital, affiliated with Shanghai Jiao Tong University, provided insightful commentary on three significant research findings in the ACLF field. These studies delve into the roles and effects of immunosuppression and microbiome variations in acute decompensation (AD) of cirrhosis and ACLF, offering new perspectives for understanding the complex mechanisms of liver disease progression and potential targets for developing new ACLF treatment strategies.

Traditionally, radiation dosage for yttrium-90 (90Y) resin microsphere radiation segmentectomy (RS) was determined using body surface area or partition models, which often resulted in lower prescription activities. Recent studies have used the Medical Internal Radiation Dosimetry (MIRD) formula to determine radiation doses, providing higher tumor absorption doses. A recent retrospective study published in Radiology by Beth Israel Deaconess Medical Center, Harvard Medical School, demonstrated that hepatocellular carcinoma (HCC) patients receiving 90Y resin microsphere RS achieved high tumor absorption doses and sustained tumor remission with good safety profiles. International Hepatology invited Professor Lin Zhang from the Tsinghua University Affiliated Beijing Tsinghua Chang Gung Hospital Hepato-Pancreato-Biliary Interventional Center to introduce and comment on this study.

From June 5-8, 2024, the European Association for the Study of the Liver (EASL) Annual Meeting was held in Milan, Italy. This event brought together over 7,000 liver disease specialists from around the world. On the third day of the conference, "Hepatology Digest" invited Dr. Wenyi Gu, a protégé of Professors Jonel Trebicka from University Hospital Münster and Hai Li from Renji Hospital Affiliated with Shanghai Jiao Tong University School of Medicine, to share her insights on two exciting studies presented at this year's Milan EASL conference and her takeaways from the event.

From June 5 to 8, 2024, the European Association for the Study of the Liver (EASL) Annual Meeting was successfully held in Milan, Italy. During the conference, Professor Liang Peng's team from the Third Affiliated Hospital ,Sun Yat-sen University unveiled the significant link between hepatocyte pyroptosis and acute-on-chronic liver failure (ACLF). The research found that IL-1β released from pyroptotic hepatocytes activates the IL1R1/MyD88/TBK1 pathway in neutrophils, promoting the formation of neutrophil extracellular traps (NETs) and exacerbating liver injury. Through bioinformatics analysis, mouse model experiments, and clinical patient data validation, the team confirmed this mechanism and identified IL-1R1 and MyD88 as potential therapeutic targets for ACLF. This discovery provides new perspectives and strategies for the treatment of ACLF.

With the rapid development of modern medical technology, non-invasive assessment methods have attracted more and more attention. In the field of metabolically associated fatty liver disease (MAFLD), liver hardness measurement (LSM) has become an important indicator for non-invasive assessment of liver-related events. At the annual meeting of the European Association for the Study of the Liver (EASL) this year, Dr.Terry Yip of the Chinese University of Hong Kong presented an exciting research result, which explored the prognostic significance of liver hardness measurement in patients with MAFLD through a large-scale international collaborative study. The study provides a new perspective for clinicians and patients, revealing the great potential of non-invasive assessment in the management of liver disease.

From June 5 to 8, 2024, the European Association for the Study of the Liver (EASL) Annual Meeting was held in Milan, Italy. This major event brought together over 7,000 professionals, including clinicians, researchers, healthcare workers, patient representatives, and industry experts. During the conference, Professor Jian Gao Fan from the Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine presented a poster titled “ASC41, a selective THR-β agonist significantly reduces liver fat and ALT in biopsy-confirmed MASH patients after 12-week treatment: an interim analysis of a 52-week serial liver biopsy study,” which attracted considerable attention. Professor Fan shared with us the main findings and clinical significance of this research.

Chronic hepatitis B (CHB) remains a significant global health issue. At this year's European Association for the Study of the Liver (EASL) Annual Meeting, the functional cure of CHB emerged as a focal point of research. "Hepatology Digest" had the privilege of speaking with Mr. Graham Griffiths, Chief Brand Officer at Barinthus Biotherapeutics, to gain insights into the conference highlights and the latest advancements in CHB treatment. Mr. Griffiths not only shared his key takeaways from the event but also detailed the progress made in the pursuit of a functional cure for CHB. He emphasized that combining various therapeutic strategies holds promise for more effective treatments and expressed optimism about the collaborative spirit and innovative potential showcased at the conference.

Acute liver failure (ALF) is a severe liver injury caused by factors such as drugs, viruses, and ischemia-reperfusion injury, leading to massive hepatocyte apoptosis, necrosis, and potentially irreversible liver damage. The condition progresses rapidly, with high short-term mortality rates and poor prognosis, while medical treatment options are limited. Although liver transplantation is an effective strategy for treating ALF, its high cost, scarcity of donor livers, and lifelong requirement for immunosuppressants limit its clinical application. Therefore, new treatment methods for ALF are urgently needed. On June 7, 2024, at the European Association for the Study of the Liver (EASL) annual meeting in Milan, a study by Professor Yu Chen's team from Beijing YouAn Hospital, Capital Medical University, was presented as a poster (Abstract No. FRI-347). This study revealed the mechanism by which liver-derived stem cells (HYX1) can be used to treat ALF, providing new insights for the future clinical treatment of ALF.

Chronic hepatitis B (CHB) is a global public health issue, with hepatocellular carcinoma (HCC) being one of its most severe complications. Traditional viral markers have limited efficacy in predicting HCC risk, highlighting the need for new viral predictive indicators. On June 5, 2024, at the European Association for the Study of the Liver (EASL) annual meeting in Milan, Italy, Professor Jian Sun's team from Nanfang Hospital, Southern Medical University, presented a compelling poster on the predictive role of serum HBV RNA reduction in HCC risk among CHB patients undergoing nucleos(t)ide analog (NA) therapy (Abstract No. LBP-037).
