Background/aims: The role of liver biopsy has been questioned in the management of patients with hepatitis C viral (HCV) infection. The aims of this study were to determine the impact of clinical parameters and degree of inflammation and steatosis on liver fibrosis.
Patients/methods: Clinical data and liver histology findings in 510 HCV patients were analysed.
Results: Hepatitis C virus genotype 1 (GT-1) was found in 38%, GT-2 in 15% and GT-3 in 45% of patients. In liver biopsy specimens, inflammation activity was present in 68%, increased fibrosis in 19% and marked steatosis in 17% of patients. Independent clinical risk factors for the increased fibrosis were patients' age at biopsy, body mass index (BMI) and duration of HCV. Steatosis and inflammation activity were independent histological risk factors for fibrosis only in GT-1; in GT-3, only inflammation correlated independently with fibrosis.
Conclusions: Age at liver biopsy, BMI and duration of HCV were independent risk factors for increased fibrosis in HCV patients. Steatosis as a risk factor for fibrosis is evident in GT-1. When scoring liver biopsies of HCV patients, the degree of steatosis should be included in addition to fibrosis and inflammation activity.

Sorafenib (Sora) is a first-line treatment for patients with advanced hepatocellular carcinoma (HCC). It can significantly improve the survival rate of patients with advanced HCC, but it is prone to drug resistance during treatment, so the therapeutic effect is extremely limited. Here, we demonstrate that an elevated expression of protein kinase p38γ in hepatocellular carcinoma cells diminishes the tumor cells' sensitivity to Sora.

No therapy has been shown to reduce the risk of major adverse liver outcomes (MALO) in patients with cirrhosis due to metabolic dysfunction-associated steatohepatitis (MASH). The Surgical Procedures Eliminate Compensated Cirrhosis In Advancing Long-term (SPECCIAL) observational study compared the effects of metabolic surgery and nonsurgical treatment in patients with obesity and compensated histologically proven MASH-related cirrhosis. Using a doubly robust estimation methodology to balance key baseline characteristics between groups, the time-to-incident MALO was compared between 62 patients (68% female) who underwent metabolic surgery and 106 nonsurgical controls (71% female), with a mean follow-up of 10.

Advanced hepatocellular carcinoma (HCC) poses treatment challenges, especially where access to multi-kinase inhibitors and ICIs is limited by high costs and lack of insurance. This study evaluates the effectiveness of 5-fluorouracil (5-FU) plus platinum-based chemotherapy as an alternative systemic treatment for advanced HCC. A retrospective analysis of advanced HCC patients treated with 5-FU plus platinum-based chemotherapy was conducted.

Mitochondrial function is crucial for hepatic lipid metabolism. Current research identifies two types of mitochondria based on their contact with lipid droplets: peridroplet mitochondria (PDM) and cytoplasmic mitochondria (CM). This work aimed to investigate the alterations of CM and PDM in metabolic dysfunction-associated steatotic liver disease (MASLD) induced by spontaneous type-2 diabetes mellitus (T2DM) in db/db mice.
