Background: CD133 has been postulated to identify cancer stem cells (CSCs) and to play a role in tumorigenesis and cancer progression. The purpose of this study was to explore the impact of CD133 polymorphisms on viral hepatitis-induced liver cirrhosis, as well as hepatocellular carcinoma (HCC) susceptibility and prognosis.
Methodology: CD133 cells were counted and CD133 SNPs (rs3130, rs1029728, rs2240688, and rs2286455) were genotyped in HCV, HCV-liver cirrhosis, HCV-HCC, HBV, HBV-liver cirrhosis, and HBV-HCC patients and disease-free controls.
Results: The percentage of CD133 cells was observed to be significantly higher in HCV- and HBV-associated liver cirrhosis and HCC. Also, the CD133 rs3130 (C > T) TT, rs1029728 (A > G) GG, and rs2240688 (G > T) SNP TT genotypes were associated with a greater risk of liver cirrhosis and HCC development in viral hepatitis patients. Furthermore, in HCV-related HCC, rs3130 TT, rs1029728 GG, or rs2240688 TT genotypes were significantly associated with an increased number and size of focal lesions, but only the rs3130 TT genotype was associated with higher lesion size in HBV-associated HCC. In addition, individuals having rs3130 TT and rs1029728 GG genotypes had a significantly higher percentage of CD133 cells. However, only HCV-infected individuals, carrying rs2240688 TT genotype, had an elevated level of CD133 cells.
Conclusions: CD133 rs3130, rs1029728, and rs2240688 are genetic factors that can influence the susceptibility to liver cirrhosis and cancer, as well as the prognosis. As a result, CD133 cells and CD133 polymorphisms might serve as potential predictors of these illnesses, laying the groundwork for the discovery of novel therapeutic targets.

Lactulose use among patients with alcohol-related liver cirrhosis as a surrogate marker of hepatic encephalopathy: prevalence and association with mortality - a Danish nationwide cohort study.

Background & Aims: Hepatic encephalopathy (HE), one of the most serious prognostic factors for mortality in alcohol-related cirrhosis (ALD cirrhosis), is not recorded in Danish healthcare registries. However, treatment of HE with lactulose, the universal first-line treatment, can be identified through data on filled prescriptions. This study aimed to investigate if lactulose can be used as a surrogate marker of HE.

Background: Chemokines and their receptors, which regulate lymphoid organ development and immune cell trafficking, are integral to the mechanisms underlying viral control, hepatic inflammation, and liver damage in chronic hepatitis C (CHC) infection. This study explores the potential relationship between serum chemokine levels/polymorphisms and hepatitis C infection in affected individuals, with a particular focus on their utility as biomarkers across different stages of fibrosis.
Methods And Results: Serum levels of the chemokines CXCL11, CXCL12, and CXCL16 were measured in patients with mild/moderate and advanced fibrosis due to CHC, as well as in healthy controls, using the ELISA method.

The accurate assessment of body composition in cirrhosis is challenging as fluid accumulation affects most techniques. The whole-body counter is a state-of-the-art method that measures total body potassium (TBK) unbiased by fluid, from which body cell mass (BCM) is derived. This pilot study in 20 patients with cirrhosis evaluated bedside tools including the liver frailty index (LFI), bioimpedance analysis-based phase angle, calf circumference (CC), and BMI (body mass index)/edema-adjusted CC, and explored their association with TBK and BCM.
