Serum PreS1 and HBsAg ratio reflects liver fibrosis and predicts the development of hepatocellular carcinoma in chronic hepatitis B patients.

While the preS1 region of the large hepatitis B surface protein plays an essential role in hepatitis B virus (HBV) infection, the effect of preS1 on liver fibrosis and hepatocarcinogenesis in chronic hepatitis B (CHB) patients is not well known. In this study, we measured serum preS1 levels by chemiluminescent immunoassay technology in 690 CHB patients and evaluated the correlation between serum preS1 levels and HBV, liver function markers and liver inflammation, fibrosis assessed by histological findings. Predictive factors for hepatocellular carcinoma (HCC) development in patients who had no previous history of HCC at the time of preS1 level measurement were also analysed. Median hepatitis B surface antigen (HBsAg) and preS1 levels were 3.08 log IU/mL and 98 ng/mL, respectively. PreS1 values were significantly correlated with serum HBsAg (p <0.001), hepatitis B core-related antigen (HBcrAg) (p <0.001) and HBV DNA levels (p <0.01). PreS1 values were also significantly correlated with serum alanine aminotransferase levels (p <0.001) and were significantly higher in patients who had higher grading of liver inflammatory activity (p <0.05). HBsAg level was correlated, but preS1/HBsAg ratio reflected liver fibrosis staging more directly than HBsAg alone. Multivariate analysis identified age ≥53 years (hazard ratio [HR], 18.360 for <53 years; p = 0.021) and preS1/HBsAg ratio ≥0.12 (HR, 6.205 for <0.12; p = 0.040) as significant and independent factors for HCC development in CHB patients. The preS1/HBsAg ratio directly reflects liver fibrosis, and the ratio might be a predictive marker for HCC development in CHB patients.

Increasing incidence of non-HBV- and non-HCV-related hepatocellular carcinoma: single-institution 20-year study.

BACKGROUND: We previously reported on the trends in the etiologies of hepatocellular carcinoma (HCC) diagnosed in patients between 1995 and 2009. The aims of our updated study were to evaluate the incidence, nonhepatitis B and nonhepatitis C viral (NBNC) etiologies, and clinical characteristics of HCCs occurring in patients between 1992 and 2018. METHODS: The study enrolled 2171 consecutive patients with HCC between 1992 and 2018. Their medical records were reviewed. The patients were divided into two groups, patients with early diagnoses from 1992 to 2009 and those with late diagnoses from 2010 to 2018. RESULTS: NBNC-HCC occurred in 514 patients (23.6%). The percentage of patients with HCC who had NBNC-HCC increased from 26.5% in 2009 to 46.3% in 2018. Patients with NBNC-HCC were older (median ages from 67 to 73 years). Type 2 diabetes mellitus (48.5-60.3%: P = 0.008), hypertension (48.5-57.4%: P = 0.047), and hyperlipidemia (39.2-53.8%: P = 0.001) increased significantly in recent years. The median FIB-4 index decreased (4.37-3.61: P = 0.026) and the median platelet count increased (15.1-17.9 × 104/µL: P = 0.013). Among the 514 patients with NBNC-HCC, 194 underwent hepatic resection for nonalcoholic steatohepatitis (NASH) (15%), alcoholic liver disease (ALD) (29%), and cryptogenic hepatitis (56%). Cirrhosis was detected in 72%, 39%, and 16% of patients with NASH, ALD, and cryptogenic hepatitis, respectively. The prevalence of cirrhosis in patients with NASH was significantly higher than the prevalence of cirrhosis in the other groups (P < 0.001). Overall, 70% of the non-malignant liver tissue of patients with NBNC-HCC was not involved with cirrhosis. On the other hand, the median FIB-4 index in patients with cryptogenic HCC was 2.56, which was a significantly lower value than those values in the other groups of patients. The FIB-4 index considered as one of useful screening of HCC. CONCLUSIONS: The prevalence of NBNC-HCC has increased rapidly even in a regional university hospital. Metabolic syndrome may be an important risk factor for HCC. HCC was also found in patients with non-cirrhotic livers. The FIB-4 index may be a useful screening method for HCC in patients with NBNC.

Risk factors for histological progression of non-alcoholic steatohepatitis analyzed from repeated biopsy cases.

BACKGROUND AND AIM: The most important prognostic factor for non-alcoholic steatohepatitis (NASH) is liver fibrosis. The aim of this study is to examine clinical parameters involved in pathological progression in NASH patients who underwent repeated liver biopsy and to analyze the response to treatment with respect to NASH-related single nucleotide polymorphisms (SNPs). We performed longitudinal analysis of genetic and clinical factors associated with progression of NASH. METHODS: Eighty NASH patients who had undergone serial liver biopsies were enrolled in this retrospective cohort study. Histological exacerbation was determined based on non-alcoholic fatty liver disease activity score (NAS) and liver fibrosis. RESULTS: About 22.5% had progression of fibrosis, 22.5% had improvement of fibrosis, and 55.0% had no change. NAS increased in 12.5%, decreased in 61.3%, and remained stable in the remaining 26.3%. We examined factors associated with histological progression versus non-progression. Poor response of alanine aminotransferase (ALT) levels, increase in HbA1c levels, and presence of the tumor necrosis factor risk allele in the rs1799964 SNP were identified as independent risk factors contributing to histological progression in NASH patients. In addition, we found that the histological progression rate varies with ALT response, HbA1c levels, and rs1799964 genotype. CONCLUSIONS: In this study, we clarified the serum ALT level and the clinical significance of HbA1c to evaluate the progression of fibrosis in Japanese NASH patients. Furthermore, the tumor necrosis factor SNP was more likely to be involved in the response than PNPLA3 SNP. By simultaneously evaluating three factors, it is possible to estimate the risk of histological progression more accurately.

The impact of interferon-free direct-acting antivirals on clinical outcome after curative treatment for hepatitis C virus-associated hepatocellular carcinoma: Comparison with interferon-based therapy.

BACKGROUND AND AIM: To examine the effect on recurrence and survival of treatment by interferon (IFN)-free direct-acting antivirals (DAA) for patients with hepatitis C virus (HCV)-associated hepatocellular carcinoma (HCC) who underwent primary curative treatment. METHODS: This was a retrospective cohort study of 250 patients with HCV who had received curative treatment for primary HCC. As anti-HCV treatment after HCC treatment, 38 patients received IFN-free DAA therapy (DAA patients) and 94 received IFN-based therapy (IFN patients). The recurrence of HCC and overall survival of the patient groups were compared in a case-control study. RESULTS: The cumulative HCC recurrence rates at 1, 3, and 5 years were 5%, 39%, and 39% for DAA patients and 0%, 46%, and 62% for IFN patients, respectively (P = 0.370). Multivariate analysis of the HCC recurrence identified treatment responses (sustained virological response [SVR]: hazard ratio [HR] 2.237; P = 0.003) as an independent predictive factor. The cumulative overall survival rates at 3 and 5 years were 96%, 96% for DAA patients and 93%, 73% for IFN patients, respectively ( P = 0.163). Multivariate analysis identified treatment responses (SVR: HR 8.742; P < 0.001) as independent predictors of overall survival. Propensity score matching analysis showed no significant difference in HCC development rates and overall survival rates in the two groups. CONCLUSIONS: We found that SVR obtained after curative treatment for primary HCC suppressed recurrence and improved overall survival. And, IFN-free DAA therapy after curative treatment for primary HCC could predict improving overall survival and suppressed HCC recurrence.

Comparison of Outcome of Hepatic Arterial Infusion Chemotherapy Combined with Radiotherapy and Sorafenib for Advanced Hepatocellular Carcinoma Patients with Major Portal Vein Tumor Thrombosis.

OBJECTIVE: To compare the outcome of hepatic arterial infusion chemotherapy combined with radiotherapy (HAIC + RT) versus sorafenib monotherapy in patients with advanced hepatocellular carcinoma (HCC) and major portal vein tumor thrombosis (PVTT). METHODS: This retrospective study included 108 HCC patients with PVTT of the main trunk or first branch and Child-Pugh ≤7. Sixty-eight received HAIC + RT and 40 received sorafenib. Patients were then assigned to the HAIC + RT group (n = 36) and the sorafenib group (n = 36) through case-control matching. The decision to treat with HAIC + RT or sorafenib was left to the attending physician. RESULTS: The median overall, progression-free, and postprogression survival were significantly longer in the HAIC + RT group than in the sorafenib group (9.9 vs. 5.3, p = 0.002; 3.9 vs. 2.1, p = 0.048; and 3.7 vs. 1.9 months, p = 0.02, respectively). Multivariate analysis identified HAIC + RT (hazard ratio = 2.02; 95% confidence interval, 1.14-3.57; p = 0.01) as a significant and independent determinant of overall survival. CONCLUSIONS: In patients with advanced HCC and major PVTT, survival was significantly longer in those treated with HAIC + RT than with sorafenib.

Clinical outcomes of sorafenib treatment failure for advanced hepatocellular carcinoma and candidates for regorafenib treatment in real-world practice.

AIM: As second-line therapy, regorafenib has been shown to provide a survival benefit for patients with hepatocellular carcinoma (HCC) who progress on sorafenib. In this retrospective study, we assessed the clinical outcomes of sorafenib treatment failure with regard to second-line chemotherapy. METHODS: Patients (n = 160) with advanced HCC, Child-Pugh A liver function and Eastern Cooperative Oncology Group performance status (ECOG PS) 0-1 treated with sorafenib between June 2009 and September 2016 were enrolled. Among 147 patients with progressive disease (PD), we defined those with Child-Pugh A liver function and ECOG PS 0-1 at progression as candidates for second-line chemotherapy and those who had tolerated sorafenib (≥400 mg/day for ≥20 of the last 28 days of treatment) as candidates eligible for regorafenib treatment. RESULTS: Among all 160 patients, median overall survival was 10 months, and median progression-free survival was 3.5 months. Among the 147 patients with PD, 74 (50.3%) were candidates for second-line chemotherapy, and 45 (30.6%) were eligible for regorafenib treatment. The median post progression survival of the candidates for second-line chemotherapy (8.8 months) was statistically longer (P = 0.0002) than that of the non-candidates (3.6 months). Predictive factors for candidates were absence of macroscopic vascular invasion (MVI) (odds ratio [OR], 0.39; P = 0.009) and serum albumin >3.5 g/dL (OR, 3.3; P = 0.005) at sorafenib initiation. CONCLUSION: Among patients with PD on sorafenib, approximately 30% were eligible for regorafenib treatment, whereas few patients with MVI or hypoalbuminemia at sorafenib initiation were eligible for regorafenib treatment.

Comparison of hepatic arterial infusion chemotherapy between 5-fluorouracil-based continuous infusion chemotherapy and low-dose cisplatin monotherapy for advanced hepatocellular carcinoma.

AIM: The aim of this study is to compare the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) between 5-fluorouracil (5-FU)-based continuous infusion chemotherapy and low-dose cisplatin (CDDP) monotherapy in patients with advanced hepatocellular carcinoma (HCC). METHODS: Patients were grouped according to HAIC regimen (5-FU group, n = 317/CDDP group, n = 66). A two-to-one match was created using propensity score analysis (5-FU group, n = 102/CDDP group, n = 51). After matching, response rate (RR) and adverse events as primary end-points, and survival and progression-free survival as secondary end-points, were analyzed. RESULTS: In the analysis of primary end-points, the RR in the 5-FU group was significantly higher than in the CDDP group (32.4% vs. 15.7%, P = 0.033). In patients with a Child-Pugh (CP) score of 5-7, the RR in the 5-FU group was significantly higher than that in the CDDP group (36.1% vs. 15.4%, P = 0.020). In those with a CP score of 8-9, there was no significant difference in RR between the two groups (15.8% vs. 16.6%, P = 1.000). The reservoir system-related complications were 9.8% in the 5-FU group, and there was no significant difference in the incidence of grade 3/4 adverse events between the two matched groups (P > 0.05). In terms of secondary end-points, the median survival time was 9.1 and 8.7 months for the 5-FU and CDDP groups, respectively (P = 0.4917). Progression-free survival was 3.9 months for the 5-FU group and 4.9 months for the CDDP group (P = 0.4). CONCLUSIONS: 5-Fluorouracil-based continuous infusion chemotherapy could be suitable for advanced HCC patients with a CP score of 5-7 considering the treatment response.

Efficacy of Lusutrombopag for Thrombocytopenia in Patients with Chronic Liver Disease Scheduled to Undergo Invasive Procedures.

Objective Lusutrombopag is a thrombopoietin receptor agonist that improves thrombocytopenia in patients with chronic liver disease scheduled to undergo invasive procedures. However, information on the efficacy of repeated lusutrombopag treatment and factors associated with the treatment is scarce. We analyzed the efficacy of repeated lusutrombopag treatment and the factors associated with a response to lusutrombopag. Methods Thirty-nine patients with chronic liver disease who received lusutrombopag treatment before undergoing invasive procedures were enrolled in this retrospective study. Of the 39 patients, 10 received lusutrombopag treatment multiple times for a total of 53 regimens of lusutrombopag treatment. Changes in platelet counts, the effects of repeated lusutrombopag treatment, and factors associated with response to lusutrombopag were analyzed. Results The median platelet count increased significantly from 4.5×104/µL before lusutrombopag treatment to 7.2×104/µL before the invasive procedure (p<0.01), and patients undergoing 49 of the 53 (92%) treatment regimens succeeded in undergoing invasive procedures without needing platelet transfusions. In patients who received lusutrombopag treatment repeatedly, the median platelet count significantly increased following the second administration of lusutrombopag, and the effects of lusutrombopag were similar between the first and second administration. A multivariate analysis identified the absence of diabetes mellitus (odds ratio, 5.56 for presence; p=0.04) as a significant and independent predictor of a response to lusutrombopag. Conclusion Lusutrombopag treatment significantly increased platelet counts in patients with chronic liver disease, making it possible to receive invasive procedures. The treatment produced identical effects when it was repeated. The efficacy of lusutrombopag might be decreased in patients with diabetes mellitus.

Levocarnitine Use Is Associated With Improvement in Sarcopenia in Patients With Liver Cirrhosis.

Although the effect of levocarnitine (L-carnitine) on hyperammonemia has been reported in patients with liver cirrhosis (LC), its effect on sarcopenia remains to be elucidated. We assessed the effects of L-carnitine on sarcopenia in patients with LC. We retrospectively evaluated 52 patients with LC who were treated with L-carnitine for more than 3 months between February 2013 and June 2017. Computed tomography was used to measure the cross-sectional area of the skeletal muscles at the level of the third lumbar vertebra. The relative change in skeletal muscle index (SMI) per year (ΔSMI/year) was computed in each patient. We evaluated the relationship between ΔSMI/year and various parameters, such as age, sex, liver functional reserve, and dose of L-carnitine. The median ΔSMI/year for all patients was -0.22%. The ΔSMI/year values in Child-Pugh classes A, B, and C were not significantly different among the three groups. There was no significant relationship between ΔSMI/year and sex, age, body mass index, and sarcopenia. Multivariate analysis showed that only a high dose of L-carnitine (odds ratio [OR], 4.812; 95% confidence interval [CI], 1.233-18.784; P = 0.024) was associated with increased muscle mass. The L-carnitine high-dose group included a significantly larger number of patients with increased muscle mass compared with the low-dose group (OR, 3.568; 95% CI, 1.138-11.185; P = 0.027). Administration of L-carnitine led to a significant and gradual reduction in serum ammonia levels. Conclusion: L-carnitine seems to suppress the progression of sarcopenia dose dependently, and this was noted to be associated with the improvement of hyperammonemia in patients with LC.
