BACKGROUND: We recently reported the real-world changes in the etiologies of liver cirrhosis (LC) based on nationwide survey data and assessed the etiologies of LC with hepatocellular carcinoma (HCC). METHODS: Fifty-five participants from 68 institutions provided data on 23,637 patients with HCC-complicated LC. The changing trends in etiologies were assessed. We further analyzed the data from 29 hospitals that provided the annual number of newly identified HCC-complicated LC patients from 2008 to 2016 (N = 9362) without any missing years and assessed the transition in the real number of newly identified HCC-complicated LC cases. RESULTS: In the overall cohort, hepatitis C virus (HCV) infection (60.3%) and hepatitis B virus (HBV) infection (12.9%) were the leading and third-most common causes of HCC-complicated LC in Japan, respectively. HCV infection was found to be the leading cause throughout Japan. The rate of viral hepatitis-related HCC decreased from 85.3 to 64.4%. Among non-viral etiologies, notable increases were observed in nonalcoholic steatohepatitis (NASH)-related HCC (from 1.5 to 7.2%) and alcoholic liver disease (ALD)-related HCC (from 8.5 to 18.6%). Regarding the real number of newly diagnosed patients, the number of patients with viral hepatitis-related HCC decreased, while the number of patients with non-viral HCC, particularly NASH-related HCC, increased. CONCLUSIONS: Viral hepatitis has remained the main cause of HCC in Japan. However, the decrease in viral hepatitis-related HCC, particularly HCV-related HCC highly contributed to the etiological changes. In addition, the increased incidence of non-viral HCC, particularly NASH-related HCC, was involved in the changing etiologies of HCC-complicated LC in Japan.

A 64-year-old man in whom benign hyperbilirubinemia had been identified was found to suffer from acute hepatitis E. Laboratory examination of the patient revealed high transaminase levels and hyperbilirubinemia, suggesting acute hepatitis, while the prothrombin time was within the normal range. The transaminase levels decreased and prothrombin time remained within the normal range; however, hyperbilirubinemia worsened to 39 mg/dl. The patient developed the complications of acute renal failure and sepsis, and eventually died. An autopsy was performed that showed no liver atrophy, liver fibrosis progression, or massive necrosis. The lung and kidney were revealed to be positive for fungal infection. The kidney was revealed to exhibit tubular conges-tion with bile. The present case offers information on the clinical course of acute hepatitis E in relatively elderly patients.

Health-related quality of life (HRQOL) is lower in individuals with autoimmune hepatitis (AIH) than in the general population. However, previous evaluations of HRQOL for AIH have included a broad range of disease activities. The aim of this study was to clarify HRQOL among patients with AIH in remission.We assessed HRQOL in patients with AIH in remission, patients with chronic hepatitis C (CHC) with eradicated hepatitis C virus (HCV) and patients with primary biliary cholangitis (PBC) using the Japanese version of the Chronic Liver Disease Questionnaire (CLDQ).Participants comprised 62 patients with AIH in remission, 39 patients with CHC with eradicated HCV and 66 patients with PBC. Median ages of patients were 63, 69, and 64 years, respectively. Overall score (5.6 vs 5.9, P = .02) and fatigue (5.2 vs 5.6, P = .01) and worry (5.6 vs 6.0, P = .01) domain scores of the CLDQ were significantly lower in patients with AIH in remission than in CHC with eradicated HCV, and similar to scores except for the systemic symptoms domain in patients with PBC. Disease duration was associated with lower scores on systemic symptoms and activity domains of the CLDQ in patients with AIH in remission.Patients with AIH in remission show impaired HRQOL associated with disease duration.

The Japanese diagnostic guidelines for autoimmune hepatitis (AIH) were proposed in 2014. This study aimed to determine the trends and characteristics of AIH based on a Japanese nationwide survey. Data for 796 patients who were newly diagnosed with AIH from 2014 to 2017 were collected from January to March, 2019 from 54 hospitals throughout Japan. Clinical characteristics, including treatment, were compared with those reported in a prior 2015 survey. The population had a median age of 63 years at diagnosis, and the male to female ratio was 1:5.3. The numbers of women was significantly lower in this survey than in the 2015 survey. Moreover, the incidence of AIH with histological acute hepatitis increased significantly from 11.0 to 21.7%. The changes in the laboratory findings, such as in transaminase and immunoglobulin G levels and antinuclear antibody titers, as well as in prednisolone treatment, reflected an increasing incidence of acute AIH. The clinical characteristics of AIH changed rapidly, in parallel with the increasing incidence of acute AIH. The elucidation and diagnosis of AIH with acute hepatitis are important in the management of AIH.

Radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) is a promising method for controlling tumors, although it does not entirely eliminate recurrence. Oxidative stress is associated with the progression of hepatocarcinogenesis, while also acting as an anticancer response. The objective of the present study was to investigate the factors influencing post-RFA outcomes. We recruited 235 newly diagnosed HCC patients who received RFA for single tumors. The patients with recurrence were sub-grouped into early and segmental recurrence groups. The characteristics of the sub-grouped patients were evaluated, including by measuring oxidative stress marker reactive oxygen metabolites and antioxidant marker OXY-adsorbent tests. The factors associated with poor survival were a high Child-Pugh score and early recurrence within 2 years in the same segment. The patients who experienced recurrence within 2 years in the same segment showed a larger tumor diameter than did others. According to a multivariate analysis, the OXY values were also significantly low in these patients. In conclusion, maintaining the antioxidant reservoir function with a high OXY value might be necessary to prevent early recurrence within the RFA-treated segment.

Language：English Publishing type：Research paper (scientific journal)

Introduction: Molecular targeting drugs are recommended as second-line treatment for intrahepatic advanced hepatocellular carcinoma (HCC). However, in Asia, hepatic arterial infusion chemotherapy (HAIC) is also considered as a second-line treatment because it improves the survival of responders. The aim of this study was to predict responders and non-responders to HAIC with low-dose cisplatin plus 5-fluorouracil (LFP) using tumor markers. Objective and Methods: The data of 47 patients who received LFP for the first time in our hospital were analyzed retrospectively. We evaluated the association between treatment response by Response Evaluation Criteria in Solid Tumors and the changing ratio of the serum concentration of α-fetoprotein (AFP), Lens culinaris agglutinin-reactive fraction of AFP (AFP-L3), and des-γ-carboxy prothrombin (DCP) 2 weeks after LFP initiation. Results: The number of patients showing a complete response (CR), a partial response (PR), stable disease (SD), and progressive disease (PD) was 0 (0%), 20 (43%), 18 (38%), and 9 (19%), respectively. The AFP ratio showed significant positive correlations for PR vs. SD (p = 0.004) and PR vs. PD (p = 0.003). The DCP ratio correlated significantly for PR vs. SD (p = 0.02). The optimal cutoff values for responders were 0.79 for the AFP ratio and 0.53 for the DCP ratio. Prediction using both or either cutoff value showed 93% sensitivity, 53% specificity, a 94% negative predictive value, and a 57% positive predictive value. Conclusion: Optimal cutoff values for AFP and DCP ratios enable prediction of nonresponders to HAIC with LFP. This simple and early assessment method allows the use of HAIC and molecular targeting drugs for HCC treatment.

Chronic viral hepatitis B and C and non-alcoholic fatty liver disease (NAFLD) have been widely acknowledged to be the leading causes of liver cirrhosis and hepatocellular carcinoma. As anti-viral treatment progresses, the impact of NAFLD is increasing. NAFLD can coexist with chronic viral hepatitis and exacerbate its progression. Oxidative stress has been recognized as a chronic liver disease progression-related and cancer-initiating stress response. However, there are still many unresolved issues concerning oxidative stress, such as the correlation between the natural history of the disease and promising treatment protocols. Recent findings indicate that oxidative stress is also an anti-cancer response that is necessary to kill cancer cells. Oxidative stress might therefore be a cancer-initiating response that should be down regulated in the pre-cancerous stage in patients with risk factors for cancer, while it is an anti-cancer cell response that should not be down regulated in the post-cancerous stage, especially in patients using anti-cancer agents. Antioxidant nutrients should be administered carefully according to the patients' disease status. In this review, we will highlight these paradoxical effects of oxidative stress in chronic liver diseases, pre- and post-carcinogenesis.

Transition in the etiology of liver cirrhosis in Japan: a nationwide survey. Reviewed

Journal of gastroenterology 55 ( 3 ) 353 - 362 2020.3

Language：English Publishing type：Research paper (scientific journal)

BACKGROUND: To assess the recent real-world changes in the etiologies of liver cirrhosis (LC) in Japan, we conducted a nationwide survey in the annual meeting of the Japan Society of Hepatology (JSH). METHODS: We investigated the etiologies of LC patients accumulated from 68 participants in 79 institutions (N = 48,621). We next assessed changing trends in the etiologies of LC by analyzing cases in which the year of diagnosis was available (N = 45,834). We further evaluated the transition in the real number of newly identified LC patients by assessing data from 36 hospitals with complete datasets for 2008-2016 (N = 18,358). RESULTS: In the overall data, HCV infection (48.2%) was the leading cause of LC in Japan, and HBV infection (11.5%) was the third-most common cause. Regarding the transition in the etiologies of LC, the contribution of viral hepatitis-related LC dropped from 73.4 to 49.7%. Among the non-viral etiologies, alcoholic-related disease (ALD) and nonalcoholic steatohepatitis (NASH)-related LC showed a notable increase (from 13.7 to 24.9% and from 2.0 to 9.1%, respectively). Regarding the real numbers of newly diagnosed patients from 2008 to 2016, the numbers of patients with viral hepatitis-related LC decreased, while the numbers of patients with non-viral LC increased. CONCLUSIONS: HCV has remained the main cause of LC in Japan; however, the contribution of viral hepatitis as an etiology of LC is suggested to have been decreasing. In addition, non-viral LC, such as ALD-related LC and NASH-related LC, is suggested to have increased as etiologies of LC in Japan.

A 78-year-old man with chronic hepatitis C underwent hepatectomy for hepatocellular carcinoma (HCC) 11 years prior to presentation. He was diagnosed with multiple intrahepatic recurrences of HCC with portal vein invasion and received hepatic arterial infusion chemotherapy (HAIC) with cisplatin. He developed abdominal pain, diarrhea, and blood-stained stool following treatment. Computed tomography revealed significant bowel wall thickening throughout the colon. Colonoscopy revealed reddish edematous mucosa with a reduced vascular pattern without ischemic changes. Conservative treatment with total parenteral nutrition improved his condition and his imaging findings. This is the first report of severe colitis following HAIC with cisplatin.

BACKGROUND: Mutations in the human telomerase reverse transcriptase (hTERT) gene promoter have been reported in hepatocellular carcinoma (HCC); however, analyses of these mutations in liquid biopsies have been technically difficult because of the high GC content of the regions of interest within this promoter. We evaluated the feasibility and prognostic value of hTERT promoter mutations identified in circulating cell-free DNA (cfDNA) from the serum of patients with HCC. OBJECTIVE: A cohort of HCC patients (n = 36) who were curatively treated by surgical resection between June 2003 and September 2014 were enrolled in this study. METHODS: The presence of hTERT promoter mutations in cfDNA from the patients' serum was analyzed via modified droplet digital polymerase chain reaction, and associations were sought between specific promoter mutations and patients' disease-free survival (DFS). RESULTS: The G>A hTERT mutation at -124 bp was detected in the serum of 25 patients (69%). Although no marked differences were observed between the characteristics of the serum mutation-positive and serum mutation-negative patient groups, the DFS of patients with the mutation was significantly shorter than that of the serum mutation-negative patients (p = 0.02). Among 18 clinicopathologic and background liver factors examined, the presence of the -124 bp G>A mutation was an independent and significant predictor of patients' DFS (hazard ratio = 3.01, 95% confidence interval 1.11-10.5, p = 0.03) in multivariate analyses. CONCLUSIONS: The -124 bp G>A hTERT promoter mutation was observed in the serum of 69% of HCC patients who underwent surgical resection and was an independent predictor of disease progression in HCC.

This study will assess the safety and efficacy of the administration of adenoviral vector expressing the human-reduced expression in immortalized cells (Ad-REIC) to a liver tumor in patients with hepatocellular carcinoma (HCC) or liver metastasis of pancreatic cancer. A Phase I clinical study of Ad-REIC administration to a liver tumor in a patient with HCC or liver metastasis of pancreatic cancer will be conducted. The study is a single-arm, prospective, nonrandomized, noncomparative, open-label, single-center trial performed in Okayama University Hospital, Okayama, Japan. Ad-REIC will be injected into the liver tumor under ultrasound guidance. Ad-REIC administration will be repeated a total of three-times every 2 weeks. The primary end point is the dose-limiting toxicity and incidence of adverse events. The secondary end points are the objective response rate and disease control rate. This study aims to expand the indication of Ad-REIC by assessing its safety and efficacy in patients with HCC or liver metastasis of pancreatic cancer.
