Clin Mol Hepatol 2022;28(2):219-231.
Published online July 20, 2021
DOI: https://doi.org/10.3350/cmh.2021.0082
Background/Aims
Sarcopenia is an independent prognostic factor of liver cirrhosis (LC). However, the association between LC-related systemic inflammation and sarcopenia is unclear.
Methods
Sprague-Dawley rats were treated with thioacetamide (TAA) or saline as a control. Rifaximin was administered to TAA-induced LC rats. Enzyme-linked immunosorbent assay was performed to measure inflammatory mediators in rat serum. RT-PCR was performed to measure the molecular expression in tissues. Hematoxylin and eosin (H&E) staining and immunohistochemistry were performed to investigate tissue pathology. Serum tumor necrosis factor-α levels, liver stiffness (LS), and the L3 skeletal muscle index (L3SMI) were measured in 60 patients with chronic liver disease.
Results
LC and sarcopenia were successfully induced by TAA. Serum TNF-α levels were increased in LC rats and correlated with myostatin expression, muscle weight, and myofiber diameter. The expression of intestinal occludin and zona occludens-1 was reduced in LC rats and associated with serum TNF-α levels and sarcopenia. In patients with LS ≥7 kPa or sarcopenia, serum TNF-α levels were significantly increased, which was also confirmed when we raised the LS cutoff to 10 kPa. The L3SMI was inversely correlated with serum TNF-α levels in patients with LS ≥7 kPa. TNF-α was reduced by rifaximin, which might have resulted in reduced expression of muscular MuRF1 and myostatin and improvements in myofiber diameters within muscle tissues.
Conclusions
These results suggest that serum TNF-α is associated with LC-related sarcopenia. Rifaximin might be effective in reducing serum TNF-α levels and improving sarcopenia in LC, but these results need to be validated in future studies.

Hepatic neoplasm

Clin Mol Hepatol 2017;23(2):128-137.
Published online May 10, 2017
DOI: https://doi.org/10.3350/cmh.2016.0071
Background/Aims
Metronomic chemotherapy (MET) is frequently administered in comparatively low doses as a continuous chemotherapeutic agent. The aim of this study was to evaluate the feasibility and overall survival (OS) of MET compared to sorafenib for advanced hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT).
Methods
A total of 54 patients with advanced HCC and PVTT who had undergone MET were analyzed between 2005 and 2013. A total of 53 patients who had undergone sorafenib therapy were analyzed as the control group. The primary endpoint of this study was OS.
Results
The median number of MET cycles was two (1-15). The OS values for the MET group and sorafenib group were 158 days (132-184) and 117 days (92-142), respectively (P=0.029). The Cox proportional-hazard model showed that a higher risk of death was correlated with higher serum alpha fetoprotein level (≥400 mg/dL, hazard ratio [HR]=1.680, P=0.014) and Child-Pugh class B (HR=1.856, P=0.008).
Conclusions
MET was associated with more favorable outcomes in terms of overall survival than was sorafenib in patients with advanced HCC with PVTT, especially in patients with poor liver function. Therefore, MET can be considered as a treatment option in patients with advanced HCC with PVTT and poor liver function.

Viral hepatitis

Efficacy and safety of daclatasvir and asunaprevir for hepatitis C virus genotype 1b infection
Hee Chul Nam, Hae Lim Lee, Hyun Yang, Myeong Jun Song
Clin Mol Hepatol 2016;22(2):259-266.
Published online June 25, 2016
DOI: https://doi.org/10.3350/cmh.2016.0020
Background/Aims
The treatment strategy for hepatitis C virus (HCV) has been changing rapidly since the introduction of direct-acting antivirals such as daclatasvir (DCV) and asunaprevir (ASV). We evaluated the efficacy and safety of DCV and ASV for HCV in real-life practice.
Methods
Patients were treated with 60 mg of DCV once daily plus 200 mg of ASV twice daily for 24 weeks, and followed for 12 weeks. The primary endpoint was a sustained virological response at 12 weeks after treatment (SVR12) and safety.
Results
This retrospective study included eight patients with chronic HCV genotype 1b infection. All of the enrolled patients were diagnosed with liver cirrhosis, and their mean age was 65.75 years. One patient was a nonresponder and two patients relapsed with previous pegylated interferon (PegIFN) and ribavirin (RBV) treatment. None of the patient showed NS5A mutation. An SVR12 was achieved in 88% of cases by the DCV and ASV combination therapy. The serum transaminase level and the aspartate-aminotransferase-to-platelet ratio were improved after the treatment. DCV and ASV were well tolerated in most of the patients, with treatment discontinuation due to adverse events (elevated liver enzyme and decompensation) occurring in two patients.
Conclusions
In this study, combination of DCV and ASV treatment achieved a high sustained virological response with few adverse events even in those with cirrhosis, advanced age, and nonresponse/relapse to previous interferon-based therapy. Close monitoring of safety issues may be necessary when treating chronic HCV patients receiving DCV and ASV, especially in older patient and those with cirrhosis.
