Since the Asian Pacific Association for the Study of the Liver (APASL) published guidelines on non-cirrhotic portal fibrosis/idiopathic portal hypertension in 2007, there has been a surge in new information, especially with the introduction of the term porto-sinusoidal vascular disorder (PSVD). Non-cirrhotic intra-hepatic causes of portal hypertension include disorders with a clearly identifiable etiology, such as schistosomiasis, as well as disorders with an unclear etiology such as non-cirrhotic portal fibrosis (NCPF), also termed idiopathic portal hypertension (IPH). This entity is being increasingly recognized as being associated with systemic disease and drug therapy, especially cancer therapy.

Article Synopsis
  • - **ADCs in Cancer Therapy**: Antibody-drug conjugates (ADCs), like ado-trastuzumab emtansine (T-DM1), are a significant breakthrough in cancer treatment, specifically for HER2-positive breast cancer, allowing targeted delivery of drugs to tumor cells while sparing normal tissue, but they can cause severe toxicity requiring monitoring.
  • - **Hepatopulmonary Syndrome (HPS) Cases**: A case series of four patients who received T-DM1 revealed they developed hepatopulmonary syndrome (HPS), which involves severe respiratory issues and is linked to long-term liver damage caused by the drug.
  • - **Need for Awareness**: The findings underscore the importance of recognizing

Article Synopsis
  • - Liver is heavily impacted by alcohol misuse, with conditions ranging from simple fat accumulation to severe liver cirrhosis, and alcohol-associated hepatitis has a high risk of short-term mortality.
  • - Current research on alcohol-associated liver disease (ALD) often overlooks important aspects, focusing mainly on short-term survival instead of broader issues related to alcohol-use disorder.
  • - The authors emphasize the existing gaps in understanding ALD, describe ongoing clinical trials, and outline future research priorities for better treatment and management strategies.

Background & Aims: Kidney dysfunction is a major determinant of prognosis in patients with decompensated cirrhosis awaiting transplantation. We hypothesized that for identical model for end-stage liver disease (MELD) scores at listing, outcomes before and after liver transplantation may vary if the predominant driver of the MELD score is serum creatinine (Cr) vs. serum bilirubin (Br) or international normalized ratio (INR).

Background: The purpose of this study was to define the risk and outcomes of esophageal varices in adults with Fontan palliation and liver cirrhosis undergoing esophagogastroduodenoscopy (EGD).

Method: The results of EGD, abdominal ultrasound, and liver biopsy, as well as clinic notes from the hepatologist, were reviewed to determine the diagnosis of cirrhosis and esophageal varices. The incidence of acute gastrointestinal bleeding complication was assessed among patients with esophageal varices using the time of EGD as the baseline.

Background: Remote patient monitoring (RPM) is an emerging focus in health care, and specialized programs may reduce medical costs, supplement in-office visits, and improve patient satisfaction. In this study, we describe the development, feasibility, and early outcomes of an RPM program for patients with decompensated cirrhosis.

Methods: Forty-six patients were offered enrollment at the time of hospital discharge in the cirrhosis RPM program (CiRPM), of which 41 completed at least 30 days of monitoring.

Background And Aims: In a recent trial, patients with severe alcohol-associated hepatitis treated with anakinra plus zinc (A+Z) had lower survival and higher acute kidney injury (AKI) rates versus prednisone (PRED). We characterize the clinical factors and potential mechanisms associated with AKI development in that trial.

Approach And Results: Data from 147 participants in a multicenter randomized clinical trial (74 A+Z, 73 PRED) were analyzed.

Article Synopsis
  • - A study involving 24 medical specialists developed a clinical decision framework for managing liver cyst infections, which often require long-term hospitalization and can have serious consequences.
  • - The modified Delphi method involved three rounds of surveys and discussions to gather expert opinions on management strategies and define treatment outcomes, resulting in consensus on various aspects of the condition.
  • - The experts identified important indicators like fever and elevated C-reactive protein for treatment decisions, along with subclassifications of liver cyst infections, leading to 26 agreed-upon management statements and two treatment algorithms.

Most patients with alcohol-associated liver disease (ALD) engage in heavy drinking defined as 4 or more drinks per day (56 g) or 8 (112 g) or more drinks per week for women and 5 or more drinks per day (70 g) or 15 (210 g) or more drinks per week for men. Although abstinence from alcohol after diagnosis of ALD improves life expectancy and reduces the risk of decompensation of liver disease, few studies have evaluated whether treatment of alcohol use disorders will reduce progression of liver disease and improve liver-related outcomes. In November 2021, the National Institute of Alcohol Abuse and Alcoholism commissioned a task force that included hepatologists, addiction medicine specialists, statisticians, clinical trialists and members of regulatory agencies to develop recommendations for the design and conduct of clinical trials to evaluate the effect of alcohol use, particularly treatment to reduce or eliminate alcohol use in patients with ALD.
