Abstract
INTRODUCTION Sarcopenia is a syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength, which is commonly associated with various chronic diseases, including chronic liver diseases. Growing lines of evidence indicate that sarcopenia not only correlates with the clinical outcomes and survival of patients undergoing liver transplant, but also serves as a prognostic factor for candidates of liver transplantation and patients with hepatocellular carcinoma. Areas covered: In this review, we conducted a narrative review and search of literature from PubMed, Ovid MEDLINE, and the Cochrane Library database up to August 2018. Studies relevant to the emerging data of sarcopenia and chronic liver diseases were examined and discussed. Expert commentary: Although sarcopenia has been shown to play a vital role in the outcomes of cirrhotic patients with or without liver transplant, its impact on non-cirrhotic patients remains unclear and deserves future research efforts. To develop an effective and practical measurement of sarcopenia has become an urgent issue in the management of patients with chronic liver diseases.

Gene 2018; 649:74-79. [PMID: 29374597 DOI: 10.1016/j.gene.2018.01.077] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2017] [Revised: 01/06/2018] [Accepted: 01/23/2018] [Indexed: 12/14/2022]
Abstract
Ghrelin (GHRL) has important implications for liver disease. It has anti-inflammatory effects, regulates cell proliferation, modulates the fibrogenic response and protects liver tissue. Genetic variations in the GHRL gene may play a crucial role in the development of chronic hepatitis (CH), liver cirrhosis (LC) and hepatocellular carcinoma (HCC). Therefore, we examined the association of GHRL gene polymorphisms (rs26312 and rs27647), and its serum level to virologic responses to combined sofosbuvir and Simeprevir therapy for a course of 12 successive weeks in Egyptian chronic hepatitis C (CHC) patients. METHODS Human genomic and clinical data were collected from 100 Egyptian participants in this study, 90 HCV patients who received sofosbuvir and Simeprevir and 10 non-HCV healthy subjects. Genotyping of GHRL rs26312 and rs27647, were determined with the TaqMan qRT-PCR allele detection assay. The serum GHRL concentrations were determined using enzyme-linked immunosorbent assay (ELISA). RESULTS GHRL polymorphisms (rs26312 and rs27647) genotype distributions and allele frequencies did not differ between HCV patients and normal healthy subjects or between patient groups when compared according to the therapeutic response. In addition, we found significant lower serum GHRL levels in CHC patients compared with the healthy controls. However, there was no significant association of the GHRL rs26312 and rs27647 polymorphisms with GHRL levels in CHC patients. We conclude that GHRL SNPs (rs26312 and rs27647) do not affect response to combined sofosbuvir and Simeprevir treatment in chronic Egyptian HCV patients.

Effect of IL15 rs10833 and SCARB1 rs10846744 on virologic responses in chronic hepatitis C patients treated with pegylated interferon-α and ribavirin. Gene 2017; 630:28-34. [PMID: 28827115 DOI: 10.1016/j.gene.2017.08.005] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2017] [Revised: 07/22/2017] [Accepted: 08/03/2017] [Indexed: 12/20/2022]
Abstract
The scavenger receptor type B class I (SCARBI) is known to be involved in the entry of hepatitis C virus (HCV) into the host, while interleukin-15 (IL15) is an important cytokine in both the innate and acquired immune responses against HCV infection. We investigated the association of IL15 rs10833 or SCARB1 rs10846744 polymorphisms with treatment responses in patients with chronic HCV (CHC). SCARB1 rs10846744 and IL15 rs10833 were identified in 365 treatment-naïve CHC patients through genotyping by TaqMan® Real-Time PCR and PCR-restriction fragment length polymorphism (RFLP), respectively. Of these 365 CHC treatment-naïve patients, rapid virological response (RVR), complete early virological response (cEVR), and sustained virological response (SVR) were observed in 53.2%, 76.4%, and 66.0% of the patients, respectively. Multivariate logistic regression analysis revealed that RVR was associated with sex (P=0.016), aspartate aminotransferase (AST) (P=0.026), IL15 rs10833 (AA) genotype (P<0.001), and SCARB1 rs10846744 (CC) genotype (P<0.001), while there was a relationship between alanine aminotransferase (ALT) (P=0.013) and IL15 rs10833 (AA) genotype (P<0.001) with cEVR. Age (<40years) (P=0.001), AST (P=0.029), ALP (P=0.028), HCV genotypes (P=0.005), HCV viral load (P=0.026), IL15 rs10833 (AA) genotype (P<0.001), and SCARB1 rs10846744 (CC) genotype (P=0.001) were strongly associated with SVR. In conclusion, the SCARB1 rs10846744 (CC) and IL15 rs10833 (AA) genotypes can be considered as powerful predictors of treatment responses in CHC patients treated with an interferon-based therapy.

Abstract
The association between serum hepatitis C virus (HCV) load and hepatic injury in HCV-infected patients has been extensively investigated. The present study aimed to investigate the association between HCV load in hepatic parenchyma cells and hepatic injury in HCV-infected patients. A total of 56 HCV-infected patients were included in the present retrospective study. The serum HCV mRNA was determined using quantitative polymerase chain reaction, while the hepatic parenchyma cell volume and HCV mRNA in hepatic parenchyma cells were also determined. Hepatic injury was evaluated on the basis of the severity of inflammation and fibrosis. The results demonstrated that there were evident differences in the mean serum HCV RNA levels and the HCV load/parenchyma cell volume among the various grades of hepatic inflammation (G1-G4) when groups with the least and most inflammation were compared (G1 vs. G4; P<0.05). Significant differences in the HCV load existed between groups divided according to the fibrosis grade; in addition, differences existed between fibrosis grades S1 and S2, and S2 and S4 when comparing serum HCV RNA levels (P<0.05). Similarly, differences existed between every two fibrosis stages (S0 vs. S4, S2 vs. S3, and S2 vs. S4; P<0.05) when viral loads and parenchyma cell volumes were compared (F=2.860, P<0.05). Furthermore, the fibrosis staging was correlated with the viral load/parenchyma cell volume (F=2.670, P<0.05). In conclusion, hepatic fibrosis grade was found to be associated with HCV load in parenchyma cells. The results of the present study demonstrated that the viral load in parenchyma cells is a more appropriate index compared with the serum viral load for evaluating HCV replication in hepatocytes, and may function as an important factor in HCV-infected hepatic injury evaluation.

Abstract
The scavenger receptor type B class I(SR-BI) is a receptor for high-density lipoproteins(HDL) and one of entry factors for hepatitis C virus(HCV). We examined the association of single nucleotide polymorphisms(SNPs) of the SCARB1 gene, which encodes SR-BI, with virologic responses to pegylated interferon-based treatment in Asian chronic hepatitis C(CHC) patients. Human genomic and clinical data were collected from 156 consecutive Taiwanese HCV genotype 1 or 2 patients who received pegylated interferon plus ribavirin therapy and 153 non-HCV healthy subjects. Three SNPs(rs10846744, rs5888, and rs3782287) of the SCARB1 gene that have been linked to humans diseases were investigated. rs10846744 rather than rs5888 or rs3782287 was associated with serum HCV RNA level and sustained virologic response(SVR) to pegylated interferon plus ribavirin therapy in CHC patients(GG vs. non-GG genotype, Adjusted Odds Ratio, 95% CI: 0.32, 0.11–0.95, P = 0.039). Among patients with IL28B rs8099917 non-TT genotypes, those with rs10846744 non-GG genotype had a higher SVR rate than those with GG genotypes. In addition, patients with GG genotype had a higher fasting blood glucose level than those with CC genotype. In conclusion, SCARB1 gene polymorphisms may serve as a potential predictor of treatment responses in CHC patients receiving interferon-based therapy. (ClinicalTrials.gov number, NCT02714712).
