    Abstract Abstract Liver stiffness measurement (LSM) is a useful tool for assessing advanced liver fibrosis, an important risk factor for hepatocellular carcinoma (HCC) following hepatitis C (HCV) eradication. This study aimed to clarify the non-invasive factors associated with HCC following sustained virological response (SVR) and to identify the low-risk group. 567 patients without history of HCC who achieved SVR at 24 weeks (SVR24) after IFN-free treatment were retrospectively analyzed. The cumulative incidence of HCC and the risk factors were examined using pre-treatment and SVR24 data. The median observation period was 50.2 months. Thirty cases of HCC were observed, and the 4-year cumulative incidence of HCC was 5.9%. In multivariate analysis, significant pre-treatment factors were age ≥ 71 years (hazard ratio [HR]: 3.402) and LSM ≥ 9.2 kPa (HR: 6.328); SVR24 factors were age ≥ 71 years (HR: 2.689) and LSM ≥ 8.4 kPa (HR: 6.642). In cases with age < 71 years and LSM < 8.4 kPa at the time of SVR24, the 4-year cumulative incidence of HCC was as low as 1.1%. Both pre-treatment LSM (≥ 9.2 kPa) and SVR24 LSM (≥ 8.4 kPa) and age (≥ 71 years) are useful in predicting the risk of HCC after SVR with IFN-free treatment. Identification of low-risk individuals may improve the efficiency of follow-up.

    Abstract For long-term treatment of hepatitis B virus (HBV) infection, switching from tenofovir-disoproxil-fumarate (TDF) to tenofovir-alafenamide (TAF) may prevent renal dysfunction and bone loss. However, the precise effects of this switch on the blood lipid profile remain to be clarified. This is an important issue as TDF is known to have effects on both low- and high-density lipids. Therefore, our retrospective multi-center study aimed to evaluate the effects of switching from TDF to TAF on the lipid profile of patients with HBV infection. Samples were obtained prior to the switch from TDF to TAF and at 6-12 months after TAF initiation. In some cases, additional samples obtained pre- and post-TDF administration were available for analysis. Serum cholesterol levels, including oxidized-low-density lipoprotein (LDL) and non-high-density lipoprotein-cholesterol (HDL-c), and the rate of dyslipidemia, according to the NCEP-ATP III lipid risk classification, were analyzed. The data from 69 patients were analyzed, including 33 patients with pre- and post-TDF-initiation serum samples. Total cholesterol (T-chol), HDL-c, LDL-c, non-HDL-c, and oxidized LDL levels increased significantly after switching to TAF. With regard to sequential changes pre- to post-TAF, TDF was associated with significantly lower serum T-chol, HDL-c, and oxidized LDL-c levels, with T-chol, HDL-c, LDL-c, and oxidized LDL-c levels increasing significantly after the switch. The switch from TDF to TAF was also associated with an increase in the rate of dyslipidemia, from 33% to 39%, with an increase in the rate of severe dyslipidemia of 1.4% and 5.8%, based on T-chol and LDL-c levels. Of note, no cases of severe dyslipidemia were detected pre-TAF treatment. As oxidized LDL-c and non-HDL-c are strongly associated with atherosclerosis development, careful monitoring of lipid is needed after switching from TDF to TAF in this clinical population.

    Abstract A deteriorated liver functional reserve during systemic therapy for unresectable hepatocellular carcinoma (HCC) causes poor patient outcomes. We aimed to identify predictive factors associated with the deterioration of Child-Pugh score at 8 weeks after lenvatinib initiation. Patients with adequate clinical data and baseline preserved serum samples available were included. Baseline fibroblast growth factor (FGF)19 and 21, angiopoietin (ANG)2, and vascular endothelial growth factor (VEGF) levels were evaluated. Thirty-seven patients were included, and 6, 15, 14, and 2 experienced complete response, partial response, stable disease, and progressive disease, respectively. Twenty-four (65%) and 13 (35%) patients showed a maintained/improved and deteriorated Child-Pugh-score, respectively. While baseline clinical data, treatment response, and laboratory data were similar between these two patient groups, baseline ANG2 and VEGF levels were significantly higher (P = 0.0017) and lower (P = 0.0231), respectively, in patients with deteriorated Child-Pugh score than in those without. Based on receiver operating characteristic curve analysis, cut-off values for ANG2 and VEGF were found to be 3,108 pg/mL and 514.9 pg/mL, respectively. Among patients with low VEGF and high ANG2, 89% (8/9) exhibited a deteriorated Child-Pugh score, whereas none of the patients (0/9) with high VEGF and low ANG2 did. The deterioration of the Child-Pugh score in patients with unresectable HCC who are treated with lenvatinib may be predictable based on combined baseline serum ANG2 and VEGF levels.

    Abstract Abstract We previously revealed that Angiopoietin-2 (Ang2) predicts non-regression of liver fibrosis based on liver stiffness measurement (LSM) at 24 weeks after anti-hepatitis C virus (HCV) treatment. In this study, we extended the observational period to 96 weeks to investigate the factors associated with non-regression after treatment with direct-acting-antivirals (DAAs). Patients treated with DAAs who underwent transient elastography at baseline and 24 and 96 weeks after DAA therapy were included. Baseline and post-treatment serum Ang2 levels were measured. Liver fibrosis stages were defined based on LSM. Multivariate regression was used to evaluate factors associated with non-regression of liver fibrosis between various time points. In total, 110 patients were included. Of these, 11% showed non-regression of LSM-based fibrosis stage at 96 weeks after DAA therapy. In multivariate analysis, advanced liver fibrosis stage and high baseline Ang2 levels were significantly associated with non-regression at 96 weeks. In patients with advanced liver fibrosis (F3/4), baseline Ang2 levels were associated with non-regression of liver fibrosis stage. Between SVR24 and SVR96, post-treatment Ang2 levels and controlled attenuation parameter values at SVR24 were significantly associated with non-regression of liver fibrosis stage in patients with F3/4. Thus, serum Ang2 levels are an important target for monitoring and therapy.

    Abstract Abstract We aimed to evaluate factors associated with changes in skeletal muscle mass in hepatitis C virus (HCV)-infected patients after treatment with direct-acting antivirals (DAAs). Consecutive HCV-infected patients after treatment with DAA were recruited into the study. Patients who achieved sustained virological response (SVR); and had complete clinical information, preserved serum samples at baseline and SVR48, and skeletal muscle mass evaluations based on the psoas muscle mass index (PMI) on computed tomography at baseline and ≥ 12 months were included. Altogether, 70.7% of patients (41/58) showed increased PMI after DAA therapy, and mean relative PMI was significantly higher after DAA therapy than at baseline. There were no significant associations between baseline clinical factors routinely examined in clinical practice and increased PMI. Among factors reported to be associated with skeletal muscle loss in patients with chronic liver disease, serum zinc levels and total and free carnitine levels increased significantly after DAA therapy and only changes in serum free carnitine levels were significantly associated with an increased PMI (r = 0305, P = 0.020). In conclusion, increased skeletal muscle mass after successful HCV eradication by DAAs was significantly associated with increased serum-free carnitine levels. l-carnitine supplementation may be beneficial in patients with low skeletal muscle mass after DAA.
