AI Article Synopsis
- Liver fibrosis treatment options are currently limited, primarily relying on liver transplantation, due to its complex progression and lack of significant indicators affecting drug efficacy.
- A novel fluoropolymer has been developed for high drug loading of sorafenib and effective delivery of miR155 inhibitor, targeting hepatic stellate cells and kupffer cells to improve treatment outcomes.
- The study suggests that combined chemotherapy and gene therapy is more beneficial when administered early in the liver fibrosis progression, as it enhances therapeutic efficiency and helps prevent recurrence.
Article Abstract
The treatment options of liver fibrosis remain limited except for liver transplantation due to the complexity and slow development in its progression. Besides, liver fibrosis recurrence and intervention time have not been reported as significant indicators to affect the anti-fibrotic efficacy of tested drugs/strategies. Herein, a novel fluoropolymer is developed to achieve high drug loading of sorafenib and efficient delivery of miR155 inhibitor (anti-miR155) for dual-targeting of hepatic stellate cells (HSCs) and kupffer cells (KCs), and we report a detailed plan on the design of treatment regimen to reveal the relationship between chemogene therapy, intervention time and fibrosis recurrence. Such a combined chemo-gene therapy of sorafenib and anti-miR155 can achieve superior therapeutic efficiency by polarizing the pro-inflammatory M1 to anti-inflammatory M2 of KCs and inhibiting the proliferation of HSCs. Importantly, efficacy and recurrence prevention of chemogene therapy earlier in the liver fibrosis will be more effective than the treatment at later stage. In conclusion, this work proposes a novel strategy to improve the efficacy and prevent recurrence of liver fibrosis by dual-regulating of KCs and HSCs, and emphasizes the importance of therapy earlier in the treatment of liver fibrosis.

Genetic predisposition of metabolic dysfunction-associated steatotic liver disease: a population-based genome-wide association study.
Hepatol Int
January 2025
Division of Gastroenterology and Hepatology, Department of Internal Medicine, National Taiwan University Hospital, Taipei, Taiwan.
Background/purpose: Although metabolic dysfunction-associated steatotic liver disease (MASLD) has been proposed to replace the diagnosis of non-alcoholic fatty liver disease (NAFLD) with new diagnostic criteria since 2023, the genetic predisposition of MASLD remains to be explored.
Methods: Participants with data of genome-wide association studies (GWAS) in the Taiwan Biobank database were collected. Patients with missing data, positive for HBsAg, anti-HCV, and alcohol drinking history were excluded.

Department of Minimally Invasive Interventional Radiology, The Second Affiliated Hospital of Guangzhou Medical University, Guangzhou, 510260, Guangdong, China.
The neutrophil-to-lymphocyte ratio (NLR) may predict outcomes in end-stage liver disease, but its value after transjugular intrahepatic portosystemic shunt (TIPS) is unclear. This study explored the link between NLR and long-term outcomes in decompensated cirrhosis patients post-TIPS. We retrospectively analyzed 184 patients treated between January 2016 and December 2021, noting demographic data, lab results, and follow-up outcomes, including liver transplantation or death.

Budd-Chiari syndrome with obstruction in the inferior vena cava causes increased venous pressure in the azygous-hemiazygous system and paravertebral venous plexus, which is transmitted to the epidural venous plexus, devoid of the valves. It causes epidural venous plexus engorgement and venous congestion and may present rarely with low back pain or radiating pain. However, patients developing lower limb weakness as a complication of Budd-Chiari syndrome is an infrequent and severe presentation.

Purpose: Liver disease is associated with a range of extrahepatic complications, which have recently been expanded to include ophthalmic conditions. However, evidence is lacking regarding its impact on primary open-angle glaucoma (POAG). This study aimed to investigate whether major liver diseases, including metabolic dysfunction-associated steatotic liver disease (MASLD), alcoholic liver disease (ALD), viral hepatitis, and liver fibrosis and cirrhosis, were associated with POAG.
