Background: High-dose (HD) tigecycline is often required for severe multidrug-resistant gram-negative infections in liver failure patients, despite package recommendations to halve the dose for those with severe liver impairment. This study evaluated the efficacy and safety of different tigecycline doses in this population.
Research Design And Methods: A retrospective cohort of 192 patients with Child-Pugh grade C liver failure was divided into label-dose (LD), standard-dose (SD), and HD groups. Primary and secondary outcomes included microbial eradication, mortality, and adverse effects.
Results: The SD group achieved higher microbial eradication than LD, with comparable efficacy to HD but fewer adverse events, such as fibrinogen requirements. High-dose treatment increased mortality risk (Hazard Ratio: 1.85, = 0.062). Optimal microbial eradication and minimized adverse effects occurred with the SD group at 7 days of treatment.
Conclusions: Standard-dose tigecycline offers a balanced approach to microbial eradication and safety, making it preferable in liver failure patients.

Liver Transplant Provider Perspectives on Posttransplant Management of Alcohol Use Disorder.
Transplant Direct
April 2025
Group for Research, education, and the Future of Transplantation (GRaFT), Transplant Surgery Department, Massachusetts General Hospital, Boston, MA.
Background: Liver transplantation (LT) is the standard treatment for liver failure secondary to alcohol-associated liver disease, but limited literature and best practices exist for post-LT treatment of alcohol use disorder (AUD). This study explores current AUD management practices and providers' perceived barriers to effective post-LT AUD management.
Methods: A 45-item survey on post-LT AUD treatment practices was distributed to members of the American Society of Transplant Surgeons, the Association of Consult/Liaison Psychiatry Transplant Special Interest Group, and both the American Society of Transplantation's Liver and Intestine Community of Practice and Psychosocial and Ethics Community of Practice discussion boards, between December 2021 and April 2022.
Low-Level Viremia Impairs Efficacy of Immune Checkpoint Inhibitors in Unresectable Hepatocellular Carcinoma.

State Key Laboratory of Organ Failure Research, Guangdong Provincial Key Laboratory of Viral Hepatitis Research, Department of Infectious Diseases, Nanfang Hospital, Southern Medical University, Guangzhou, Guangdong, People's Republic of China.
Background And Aims: The impact of low-level viremia(LLV) on the efficacy of immune checkpoint inhibitors (ICIs) in unresectable hepatocellular carcinoma(uHCC) patients remains unclear. This study aims to investigate the effect of LLV on the outcomes of ICIs-based therapy in patients with uHCC.
Methods: In this multicenter retrospective study, we included patients with uHCC who received ICIs-based therapy at four centres between January 2019 and December 2022.
Short and Long-Term Outcomes of Liver Transplantation in Pediatric Patients With Inborn Errors of Metabolism: A Single-Center Study.

Department of General Surgery, Başkent University Faculty of Medicine, Ankara, Turkey.
Background: Inborn errors of metabolism (IEMs) are inherited diseases causing significant morbidity and mortality, particularly in childhood. Liver transplantation (LT) can be curative or partially effective for these diseases. LT for IEMs has increased, making IEMs the second most common reason for pediatric LT after biliary atresia.

Aflatoxin, produced by and fungi, contaminates a broad range of crops such as maize, nuts, and cotton. Aflatoxin exposure causes growth failure, immune suppression, and liver cancer. While several systematic reviews have assessed the link between aflatoxin exposure and growth development in humans, there is a lack of reviews on the associations between aflatoxin exposure and micronutrient levels/status.
