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

Labor analgesia (LA) is associated with the potential hazard of high-risk delivery, such as cesarean section (CS) and instrumental vaginal delivery (IVD), and adverse neonatal outcomes such as neonatal asphyxia and respiratory distress. The objective was to examine the impact of LA on mode of delivery and neonatal outcomes and to counsel pregnant women about a potentially higher risk and allow them to decide LA or non-LA. This retrospective cohort study containing 5,184 pregnant women analyzed the association between LA and both mode of delivery and neonatal outcomes. LA increased the risk of IVD (Adjusted Odds Ratio [AOR] 3.25, 95% confidence interval [95%CI] 2.51–4.20) but decreased that of CS (AOR 0.52, 95%CI 0.44–0.60). Two factors (advanced maternal age [AOR 1.70, 95%CI 1.33–2.17] and primipara [AOR 4.72, 95%CI 3.30–6.75]) increased the risk of IVD. We should carefully consider the indication of LA for cases with these two factors since LA can increase the risk of IVD and adverse neonatal outcomes.

AIM We analyzed the impact of hepatitis C virus eradication by direct-acting antiviral (DAA) therapy on the risk of development of hepatocellular carcinoma (HCC), prognosis, and portal hypertension in patients with liver cirrhosis. METHODS The rate of HCC development and overall survival after achievement of sustained virological response (SVR) in 173 DAA-treated compensated cirrhosis patients without HCC history were retrospectively compared with that of 125 cirrhosis patients who achieved SVR by interferon (IFN)-based therapy or that of 85 cirrhosis patients who failed to respond to anti-HCV therapy. Changes in esophagogastric varices (EGV) and incidence of portosystemic encephalopathy were analyzed in 87 consecutive cirrhosis patients. RESULTS The cumulative HCC development rates at 1, 3, and 5 years were 2%, 7%, and 7% for the DAA-SVR group, significantly lower than the 3%, 7%, and 18% for the non-SVR group (log-rank, P

The current status of Helicobacter pylori infection in Japan has not been investigated. We evaluated the status of H. pylori infection in a Japanese general population using large-scale resident-register-based sampling.All 6069 adults in a rural town and 6000 adults in two urban cities (3000 each), selected by register-based random sampling, were enrolled in our health check-up program. Antibody titers against Helicobacter pylori (cut-off value was 3 U/mL by Eiken E-plate) were evaluated, and subjects with a positive result were encouraged to undergo further examinations.A total of 1586 subjects participated in serum sampling. The overall prevalence of H. pylori infection was 40.0% (634/1586), and it increased with age both in rural and urban areas. Although the overall positive rate was higher in the rural area (49.4%) than in the urban areas (35.6 and 32.3%), there was no difference in H. pylori status of younger subjects between the two areas. Among 634 patients with a positive titer, 374 (59.0%) underwent further examinations including endoscopic examination, and 180/634 (28.4%) patients received eradication therapy. Gastric neoplasms (three adenocarcinomas and one adenoma) were found in our screening program.We clarified population-based random sampling data of H. pylori infection in a Japanese general population. In younger subjects, a decrease in the prevalence of H. pylori infection was confirmed both in rural and urban areas. This provides basic information for establishing a strategy to reduce gastric cancer deaths.

Background: We previously reported the trends of etiologies of hepatocellular carcinoma (HCC) between 1995 and 2009. By updating this study, we aimed to evaluate the incidence of HCC with non- hepatitis B viral and non- hepatitis C viral (NBNC) etiologies and explore the clinical characteristics, also.Methods: Consecutive 2171 HCC patients at our institution were enrolled between 1992 and 2018 in this retrospective cohort study. A comparative study was conducted by dividing into two groups, an early group from 1992 to 2009 and a late group from 2010 to 2018.Results: NBNC-HCC account for 514 patients (23.6%). The proportion of NBNC-HCC has continued to increase from 26.5% in 2009 to 46.3% in 2018. NBNC-HCC were getting older (median ages, 67 to 73 years). Type 2 diabetes mellitus (48.5% to 60.3%: P=0.008), hypertension (48.5% to 57.4%: P=0.047), and hyperlipidemia (39.2% to 53.8%: P=0.001) has increased significantly in recent years. The median FIB-4 index have decreased (4.37 to 3.61: P=0.026) and the median platelet counts have increased (15.1 to 17.9: P=0.013) significantly. Among 514 NBNC-HCC, 194 patients underwent hepatic resection in which 14.9%, 29.3%, and 55.8% were based on nonalcoholic steatohepatitis (NASH), alcoholic liver disease (ALD), and cryptogenic, respectively. Cirrhosis was detected in 72.4%, 38.6%, and 15.5% of NASH, ALD and cryptogenic, respectively. The prevalence of cirrhosis in NASH were significantly higher than other groups (PConclusions: NBNC-HCC has rapidly been increasing in recent years even in regional university hospital. The presence of metabolic syndrome may be important risk factors. Furthermore, HCC from non-cirrhotic liver needs attention carefully. Accordingly, it is speculated that these patients should receive periodic surveillance for HCC development.

AIM Liver biopsy is still required for the diagnosis of hepatocellular ballooning and inflammation, which are important histological features of non-alcoholic steatohepatitis. We undertook this multicenter, cross-sectional study to identify novel blood markers for the diagnosis of hepatocellular ballooning. METHODS We enrolled 176 patients, of whom 132 were proven by liver biopsy as having non-alcoholic fatty liver disease (NAFLD) and classified as non-ballooning (ballooning grade 0) (n = 83) or ballooning (ballooning grade 1 and 2) (n = 49) by a central pathology review. We carried out gas chromatography-mass spectrometry, hydrophilic interaction liquid chromatography tandem mass spectrometry, and lipidomics with plasma. RESULTS As correlates of hepatocellular ballooning, among the clinical parameters, serum type IV collagen 7S correlated most significantly with the ballooning grade (correlation coefficient [CC] = 0.463; P

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

Background and Aim The relationship between the presence of villous edema (VE) in portal hypertensive enteropathy (PHE) and clinical factors remains unclear. The aim of this study was to reveal the clinical factors related to VE in patients with liver cirrhosis (LC), and investigate the clinical significance of VE. Methods Between February 2009 and September 2016, 363 consecutive patients with liver cirrhosis underwent capsule endoscopy (CE) for diagnosing PHE at Hiroshima University Hospital. We evaluated the relationship between the presence of VE and patients’ clinical characteristics, findings of esophagogastroduodenoscopy and computed tomography, and survival time. Results VE was observed in 131 patients (36%), and severe lesions were found in 71 (20%). The presence of VE was significantly greater in patients with Child-Pugh classification B or C, esophageal varices (EVs), portal hypertensive gastropathy (PHG), ascites, portal vein thrombosis (PVT), and splenomegaly. In multivariate analysis, Child-Pugh class B or C, EVs, PVT, and splenomegaly were significant predictive factors for the presence of VE. Severe VE was significantly greater in patients with Child-Pugh class B or C, serum albumin level ≤3.2 mg/dL, PHG, and PVT. In multivariate analysis, PHG, Child-Pugh class B or C, PVT, and serum albumin level ≤3.2 mg/dL were significant predictive factors for severe VE. Conclusions Clinical factors related to portal hypertension were significantly correlated with VE. In particular PVT was correlated with the appearance and exacerbation of VE. Periodic CE in LC patients may lead to early detection of portal hypertension and PVT.

Background/Aims: The clinical course and exacerbation of portal hypertensive enteropathy (PHE) are yet to be fully clarified. This study aimed to identify factors related to PHE exacerbation in patients with liver cirrhosis (LC). Methods: Fifty patients with LC (33 male; mean age, 67 years), who underwent capsule endoscopy (CE) at the Hiroshima University Hospital between February 2009 and September 2015, were followed up for >6 months. Exacerbation is defined as the appearance of new lesions or worsening of existing lesions. The association between PHE exacerbation and the clinical factors was evaluated. Results: PHE exacerbation was identified in 24 out of 50 (48%) of cases: erythema (14 cases); angioectasia (11 cases); erosions (9 cases); villous edema (8 cases); and esophageal varices (EVs; 6 cases). The following factors were significantly associated with PHE exacerbation: portosystemic shunts, EVs and portal hypertensive gastropathy (PHG) exacerbation. After therapy, CE findings among the 24 cases were as follows: villous edema (19 cases); erythema (17 cases); angioectasia (16 cases); erosions (12 cases); and EVs (9 cases), and no observable abnormalities in 2 cases. On multivariate analysis, exacerbation of EVs and PHG were independent predictors of PHE exacerbation. Conclusion: EVs and PHG exacerbation may predict PHE exacerbation in patients with LC.

AIM The aim of this study was to determine the risk factors for worsening of gastroesophageal varices (GEVs) and development of portosystemic encephalopathy in patients with hepatitis B virus (HBV)-related cirrhosis during nucleos(t)ide analog (NA) treatment. METHODS One hundred and thirty-seven patients with HBV-related cirrhosis were enrolled in this retrospective cohort study. Findings of portal hemodynamics with computed tomography, liver function, and endoscopic examinations during NA treatment were assessed. RESULTS Among 137 patients, feeding vessels for GEVs (left gastric vein, posterior gastric vein, and short gastric vein) were present in 56 (41%) patients, and extrahepatic portosystemic shunt (paraesophageal vein, paraumbilicul vein, and splenorenal shunt) were present in 36 (26%) patients at the start of NA treatment. Although NA treatment was successful, significant improvements were not observed in portosystemic collateral vessels 3 years after NA treatment and GEVs were exacerbated in 48 (35%) patients. The cumulative 5- and 10-year exacerbation rate of GEVs was 27% and 50%, respectively. By multivariate analysis, the existence of feeding vessels for GEVs at the start of NA treatment was the independent predictive factor for the exacerbation of GEVs (P

The risk factors in the progression of nonalcoholic fatty liver disease (NAFLD) have not been fully clarified. Porphyromonas gingivalis (P.g) has been considered to be a confounding risk factor for systemic diseases. We aimed to evaluate the effect of P.g infection on risk of progression to NASH. (1) Serum IgG antibody titers against P.g fimbriae (fimA) in 200 biopsy-proven NAFLD patients were measured by ELISA and compared with histological findings. (2) C57BL/6J mice were fed a control diet (CD) or high-fat diet (HFD) with or without P.g-odontogenic infection and analyzed histologically. Mouse livers were analyzed using CE–TOFMS and LC–TOFMS. (1) A significant correlation between fibrosis progression and antibody titers against P.g possessing fimA type 4 was identified (P = 0.0081). Multivariate analysis identified older age and type 4 P.g-positivity as risk factors for advanced fibrosis. (2) Fibrosis and steatosis were more severe in HFD P.g(+) mice compared with HFD P.g(−) mice. In metabolome analysis, fatty acid metabolism was significantly disrupted with HFD in P.g-infected mouse livers. Monounsaturated/saturated fatty acid ratios were significantly higher in the HFD P.g(+) group than in the HFD P.g(−) group (P

Background/Aim To evaluate the safety and efficacy of stereotactic body radiotherapy (SBRT) for the treatment of hepatocellular carcinoma (HCC) in elderly patients. Methods From 2008 to 2015, 117 patients with HCC (≦3 nodules, ≦30 mm in diameter, Child-Pugh score ≦7, no vascular or extracellular metastasis) were treated with SBRT at our hospital. We evaluated overall survival (OS), disease-free survival (DFS), local control, and adverse events. Patients were stratified according to age 75 years and older (elderly group, n = 54) and age younger than 75 years (young group, n = 63). Results The median OS in the elderly group was not significantly different from that in the young group (52 months vs. not reached, P = 0.27). The 1, 2 and 3-year OS rates were 96.2%, 77.6% and 63.9%, respectively, in the elderly group, and 96.8%, 84.8% and 67.7%, respectively, in the young group. The median DFS in the elderly group was significantly shorter than that in the young group (13 vs. 25 months, respectively; P = 0.03). The 1, 2 and 3-year DFS rates were 50.6%, 30.4% and 26.6%, respectively, in the elderly group and 66.5%, 50.7% and 45.3%, respectively, in the young group. The 3-year local tumor control rate in the elderly group was 98.1%, and that in the young group was 98.4% (P = 0.83). There was no difference between groups in the incidence of any adverse events. Conclusions SBRT can be effective and safe for the treatment of HCC in elderly patients.

The urea cycle converts ammonia and produces urea. One form of urea cycle abnormality is ornithine transcarbamylase (OTC) deficiency. This hereditary disorder is associated with hyperammonemia. OTC deficiency commonly appears during neonatal and early childhood life and is rare in adults. We report a 69-year-old man who presented at the local hospital with 3-day loss of appetite, early morning vomiting, and state of confusion. Blood ammonia was 293 μg/dl. At 2-3 h after admission, the patient went into a deep coma. He was intubated and admitted immediately to the intensive care unit. Treatment, including sustained hemodialysis, failed to lower blood ammonia level. His grandchild died of OTC deficiency at 6 year of age. Computed tomography, magnetic resonance imaging and esophagogastroduodenoscopy showed no abnormalities. On admission to our hospital, he complained of vomiting and disturbance of consciousness, hyperammonemia, and normal anion gap. Genetic analysis showed A208T mutation. The deceased grandchild with OTC deficiency also had the same mutation. Long-term hemodialysis coupled with administration of L-arginine and lactulose resulted in improvement of blood ammonia level. Early diagnosis and treatment of adult-onset OTC deficiency are essential to avoid serious complications.

Aim To compare the efficacy and safety of edoxaban and warfarin for treatment of portal vein thrombosis (PVT) following danaparoid sodium in patients with liver cirrhosis. Methods Fifty cirrhotic patients with PVT treated initially for 2 weeks with danaparoid sodium were enrolled in this retrospective cohort study. Treatment was later switched to either edoxaban (n = 20) or warfarin (n = 30). We compared the efficacy and safety of edoxaban and warfarin for up to 6 months. The PVT volume was measured by dynamic computed tomography before treatment, at 2 weeks, and at 1, 3, and 6 months. Results There were no significant differences in the clinical characteristics of patients in the two groups. Treatment with edoxaban reduced the volume of PVT from 1.42 cm3 at 2 weeks to 0.42 cm3 at 6 months, and prevented exacerbation of PVT at 6 months after treatment with danaparoid sodium (P = 0.016). In contrast, treatment with warfarin resulted in increased PVT volume from 1.73 cm3 at 2 weeks to 2.85 cm3 at 6 months, despite the control of the international normalized ratio in 57% of the patients (P = 0.005). Multivariate regression analysis identified edoxaban therapy as the single significant and independent determinant of PVT reduction at 6 months (P = 0.0014, hazard ratio 6.400). Clinically significant gastrointestinal bleeding was encountered in 3 of 20 (15%) patients of the edoxaban group and 2 of 30 (7%) of the warfarin group (P = 0.335). Conclusion Edoxaban following danaparoid sodium is an effective anticoagulant and could be potentially considered as one of the treatment options for PVT in cirrhotic patients.

Background and Aims Daclatasvir and asunaprevir combination therapy has shown a high virological response for chronic genotype 1 hepatitis C virus (HCV) infected-patients. However, the real-world efficacy and safety of the therapy for patients with cirrhosis are unknown. Methods A total of 252 patients with genotype 1 HCV infection (158 with chronic hepatitis and 94 with compensated liver cirrhosis) were treated with 24 weeks of daclatasvir and asunaprevir combination therapy. Plasma concentrations of daclatasvir and asunaprevir at day 5 of treatment, end-of-treatment response, sustained virological response (SVR), and the frequencies of adverse events were analyzed. Result Plasma asunaprevir concentration was significantly higher, and daclatasvir concentration tended to be higher, in cirrhosis patients compared with chronic hepatitis patients. End-of-treatment response was achieved in 95.6% and 94.7% of chronic hepatitis and cirrhosis patients, respectively, and SVR was achieved in 94.3% and 92.6%. Although pre-treatment NS5A drug resistant-associated variants were detected, a high SVR rate was achieved when the population frequency of the variant was low. The frequencies of treatment-related adverse events in cirrhosis patients were similar to those in chronic hepatitis patients. Treatment discontinuation due to adverse events occurred in three and two patients in chronic hepatitis and cirrhosis groups, respectively; however, four out of five patients with treatment discontinuation nonetheless achieved SVR. Conclusion Patients with compensated liver cirrhosis have similar virological response and tolerance for daclatasvir plus asunaprevir therapy to patients with chronic hepatitis. This combination therapy might offer a safe and effective treatment for chronic HCV infected-patients with compensated cirrhosis.

Objective: To evaluate the impact of hepatitis C virus (HCV) eradication on the clinical outcome of patients with HCV-related advanced hepatocellular carcinoma (HCC) treated with sorafenib. Methods: A total of 58 HCV-related advanced HCC patients with Child-Pugh grade A disease who were treated with sorafenib were enrolled in this retrospective cohort study. Of these, 27 patients were HCV RNA negative as a result of previous antiviral therapy (sustained viral response [SVR] group), while the remaining 31 were HCV RNA positive (non-SVR group). Results: The response rate, disease control rate and median time to progression in the SVR group (6, 46.0%, and 3.8 months, respectively) were similar to those in the non-SVR group (3, 51.5%, and 2.7 months, respectively). On the other hand, the median time to treatment failure (TTTF), post-progression survival (PPS), and overall survival (OS) were significantly longer in the SVR group than in the non-SVR group (9.7, 8.5, and 15 months vs. 5.9, 5.2, and 9.3 months; p = 0.023, 0.02, and 0.014, respectively). On multivariate analysis, SVR was identified as a significant and independent determinant of PPS (p = 0.009), TTTF (p = 0.028), and OS (p = 0.01). Conclusion: HCV eradication before sorafenib treatment for HCV-related advanced HCC could prolong PPS and TTTF and improve OS.

Aims We retrospectively analyzed the clinical outcome and prognostic parameters in patients with hepatocellular carcinoma (HCC) and bone metastases who had received treatment with zoledronic acid (ZOL). Methods Ninety-nine HCC patients with bone metastases who had been treated with ZOL were enrolled in this retrospective cohort study. We analyzed the prognostic factors, including serum N-telopeptide of type I collagen (NTX) levels, as bone metabolism markers. Results The median overall survival (OS) time was 11.5 months. Child–Pugh grade A (P = 0.004) and intrahepatic tumor stage (IHTS) T0–3 (P = 0.010) correlated significantly with favorable OS. In 46 patients with grade A and T0–3, receiver operating characteristic curve analysis defined 16 nmol BCE/L serum NTX as the cut-off level for median OS. Multivariate analysis identified baseline serum NTX

Introduction: Portal hypertensive enteropathy (PHE) is a well-known small-bowel lesion that occurs with liver cirrhosis (LC) and is associated with increased hepatic venous pressure. However, it is unclear how esophageal varices (EV) treatment actually affects PHE. We aimed to analyze the effects of EV treatment on PHE. Methods: Among LC patients who underwent capsule endoscopy (CE) more than twice to confirm PHE at our hospital from February 2009 to September 2018, we targeted those with no change in the Child-Pugh classification after EV treatment for the prevention of bleeding. Patients were assigned to groups based on the EV treatment method (endoscopic injection sclerotherapy [EIS] group or endoscopic variceal ligation [EVL] group). We analyzed the PHE findings before and after treatment, and we investigated changes in the collateral vein using computed tomography imaging. Results: We analyzed 42 LC patients (27 men; mean age, 65.3 years); 20 were in the EIS group and 22 were in the EVL group. Exacerbation of PHE was significantly prevalent in the EIS group (90%) compared to that in the EVL group (50%). CE of PHE showed significantly prevalent exacerbation of villous edema in the EIS group (65%) compared to that in the EVL group (23%). Stenosis or disappearance of the feeding vessel (55%) and exacerbation of the hepatofugal collateral vein (35%) were significantly prevalent in the EIS group. Conclusions: EIS exacerbates PHE, especially villous edema, in LC patients with changes in collateral circulation.

Beckwith-Wiedemann syndrome (BWS) is a congenital overgrowth syndrome that is occasionally associated with hyperinsulinemic hypoglycemia (HH) in the neonatal period. Sotos syndrome (SS) and Kabuki syndrome (KS) are other malformation syndromes that may be complicated with HH, however, the detailed clinical characteristics of HH accompanied with these syndromes remain unclear. We herein conducted a nationwide questionnaire survey in Japan. We sent a primary questionnaire concerning the clinical experience for these syndromes to 347 perinatal care institutions. As a result, 222 departments or hospitals returned the questionnaires and the total numbers of BWS, SS, and KS patients were 113, 88, and 51, respectively. We sent a secondary questionnaire to 31 institutions where patients with these syndromes presented with HH during infancy. The secondary questionnaires were returned from the institutions and the numbers of patients were 16 for BWS, 9 for SS, and 3 for KS, respectively. Then, we compared the clinical characteristics of infants suffering from transient HH with and without these dysmorphic syndromes. As a result, BWS, SS, and KS patients showed significantly larger body size, lower Apgar scores, higher insulin levels at HH, and shorter durations of HH than non-dysmorphic infants with transient HH. We propose that a careful observation for the signs of HH, even if not specific to the syndromes, is important for the diagnosis of patients with BWS, SS, and KS in the postnatal period. © 2016 Wiley Periodicals, Inc.

Polymorphisms in the inosine triphosphatase (ITPA) gene is associated with anemia induced by peg-interferon (PEG-IFN) plus ribavirin (RBV) treatment for patients with chronic hepatitis C virus (HCV) infection. However, the effect of ITPA polymorphism on sofosbuvir plus RBV treatment is unknown. Two hundred and forty-four patients with chronic HCV genotype 2 infection without decompensated liver cirrhosis were treated with sofosbuvir plus RBV for 12 weeks. The effects of ITPA polymorphism on hemoglobin levels and RBV dose reduction and treatment response were analyzed. ITPA (rs1127354) was genotyped using the Invader assay. Multivariate regression analysis was performed to identify factors associated with sustained virological response (SVR). Overall, SVR12 was achieved in 231 (94.7%) patients, based on intention to treat analysis. During the therapy, reduction of hemoglobin levels was significantly greater in ITPA genotype CC patients than CA/AA patients. Therefore, the cumulative proportion of patients with RBV dose reduction was significantly higher and total dose of RBV was significantly lower in patients with CC genotype compared to CA/AA genotypes. SVR12 rates were similar between ITPA genotypes CC and CA/AA (94.7 and 94.4%, respectively, P = 0.933). Multivariate logistic regression analysis identified FIB4 index

Background & Aims FibroScan® is a tool for the noninvasive diagnosis of hepatic fibrosis. Previous studies have compared liver stiffness to percutaneous liver biopsy findings, but there were no studies which compared liver stiffness to liver resection specimen findings. The aim of this study was to compare FibroScan® measurements to resected liver specimen findings. Methods From April 2011 to November 2015, a total of 114 patients with liver tumor and hepatitis C were enrolled. We divided them into two groups (training set and validation set). The first 66 patients who had liver resection from April 2011 to June 2014 were considered the training set, and the other 48 patients from August 2014 to November 2015 formed the validation set. Liver stiffness was measured by FibroScan® before surgery, and specimens obtained by liver resection were evaluated according to the METAVIR system. Results Using Spearman rank correlation analysis, a positive correlation between liver stiffness measurement and liver fibrosis stage was observed (r = 0.786, p

Background: We assessed the risk factors for the development of hepatocellular carcinoma (HCC) following successful eradication of hepatitis C virus (HCV) with interferon (IFN) therapy in a long-term, large-scale cohort study. Methods: We reviewed 1094 consecutive patients with HCV who achieved sustained virological response (SVR) following IFN therapy between January 1995 and September 2013. Results: During the observation period (median 50 months: range 13–224), 36 (3%) of 1094 patients developed HCC after SVR. The median period from SVR to diagnosis of HCC was 37 months (range 17–141), and the cumulative rates of HCC at 5, 10, and 15 years were 4%, 6%, and 12%, respectively. Multivariate analysis identified old age (≥60 years, HR, 3.1: 95%CI, 1.3–6.6: P = 0.009), male sex (HR, 12.0: 95%CI, 2.8–50.0: P

Aim Older patients with chronic hepatitis C have a lower virological response to interferon (IFN)-based treatments compared to younger patients. A single nucleotide polymorphism in the IFN-λ-4 (IFNL4) gene has a potent predictive effect on treatment response to IFN-based treatments. The efficacy of simeprevir (SMV) plus pegylated-IFN (PEG-IFN) and ribavirin therapy and the predictive value of IFNL4 on the outcome of therapy for older patients have not been addressed. Methods This retrospective multicenter study included 234 consecutive Japanese patients with genotype 1 chronic hepatitis C. We assessed the predictive factors for sustained virological response (SVR) to SMV, PEG-IFN, and ribavirin triple therapy in 170 younger (

Aim Polymorphisms in the ITPA gene influence anemia during peg-interferon (PEG-IFN) and ribavirin (RBV) therapy, but their effects during triple therapy with simeprevir, PEG-IFN, and RBV are not sufficiently known. Methods We analyzed 212 patients with genotype 1 chronic hepatitis C, who were treated with simeprevir plus PEG-IFN/RBV triple therapy, and assessed the effect of the ITPA polymorphism on hemoglobin levels and RBV dose reduction. ITPA (rs1127354) and IFNL4 (ss469415590) polymorphisms were genotyped using the Invader assay. A stepwise multivariate regression analysis was carried out to identify factors associated with outcome of the therapy. Results Reduction of hemoglobin levels was similar between patients treated with simeprevir plus PEG-IFN/RBV and those treated with PEG-IFN/RBV therapy. In simeprevir plus PEG-IFN/RBV-treated patients, decreases in hemoglobin levels were faster and greater, and the cumulative proportion of patients with ribavirin dose reduction was significantly greater in ITPA genotype CC patients than in CA/AA patients. The total dose of simeprevir and PEG-IFN was similar between ITPA genotype CC and CA/AA patients. In contrast, the total dose of RBV was lower in patients with the CC genotype. Multivariate analysis showed that the IFNL4 TT/TT genotype, but not the ITPA SNP genotype, treatment history (treatment-naive or relapse during prior treatment), and treatment completion were significantly associated with outcome of therapy. Conclusion ITPA polymorphism influences hemoglobin levels and incidence of RVB dose reduction during simeprevir triple therapy, indicating the importance of monitoring anemia during treatment, particularly for ITPA genotype CC patients.

Recently, treatments for chronic hepatitis C virus (HCV) infection have been drastically improved by the development of direct-acting antiviral agents. In September 2014, dual oral therapy using daclatasvir (DCV) and asunaprevir (ASV) was approved for the treatment of chronic HCV infection in Japan. We treated a patient with HCV-related liver cirrhosis with severe leg edema due to chronic renal dysfunction using this dual oral therapy. Although serum alanine aminotransferase increased rapidly during the first week of treatment, the antiviral therapy was able to continue, and liver function recovered spontaneously. After 1 month of treatment, serum HCV RNA became continuously undetectable, and serum albumin level gradually increased. Throughout the therapy, serum creatinine level nearly normalized, and leg edema gradually improved. These improvements continued after the combination therapy was completed. HCV RNA remained undetectable following the end of therapy, and sustained virological response at 12 weeks was achieved. It has been reported that chronic HCV infection is associated with renal dysfunction and that HCV eradication can improve it. DCV and ASV combination therapy is safe for patients who have renal dysfunction and may be a suitable therapy for chronic hepatitis C patients with renal dysfunction.

Objectives This study aimed to assess the value of preoperative fluorine 18 fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET-CT) for predicting microvascular invasion (MVI) in small hepatocellular carcinoma (HCC). Methods We retrospectively examined 60 patients who received F-FDG PET-CT prior to hepatic resection for small HCC (≤30 mm) with subsequent MVI confirmation by histopathology. The associations between PET-positive status and tumor factors were assessed. Furthermore, independent predictors for MVI and diagnostic utility of each MVI predictor were assessed. Results Multivariate analysis revealed the presence of MVI as an independent predictor of PET-positive status (P = 0.023). Maximum standardized uptake value (SUVmax) of 3.2 or greater (P = 0.017) and lens culinaris agglutinin a-reactive α-fetoprotein (AFP-L3) 19% or greater (P = 0.010) were independent predictors of MVI. Areas under the receiver operating characteristic curves for SUVmax of 3.2 or greater, AFP-L3 19% or greater, and both factors combined for predicting MVI were 0.712 (0.493-0.932), 0.755 (0.563-0.947), and 0.856 (0.721-0.991), respectively. The sensitivity and specificity for predicting MVI were 77.8% and 74.5% for SUVmax of 3.2 or greater, 66.7% and 84.3% for AFP-L3 19% or greater, and 88.9% and 82.4% for the combination. Conclusions F-FDG PET-CT and AFP-L3 may be useful for predicting MVI in small HCC, and the combination of the 2 factors provided reliable assessment for selection of suitable hepatic resection and liver transplantation candidates.

To assess the outcome of stable disease (SD) patients with advanced hepatocellular carcinoma (HCC) by tumor markers after the first course of hepatic arterial infusion chemotherapy (HAIC). The study subjects were 156 HCC patients treated with HAIC and classified as Child Pugh A, with no extrahepatic metastasis, and no history of sorafenib treatment. In the study and validation cohorts, the AFP and DCP ratios of patients who were considered SD to the first course of HAIC were analyzed by AUROC for a prediction of response to the second course of HAIC. The imaging response to the first course of HAIC was classified as partial response (PR), SD and progressive disease (PD) in 29 (18.8%), 80 (51.9%), and 44 (28.6%) patients respectively. For SD patients, the a-fetoprotein (AFP) and des-y-carboxy prothrombin (DCP) ratios of patients who were considered SD to the first course of HAIC were analyzed by the receiver operating characteristic curve for prediction of response to the second course of HAIC in the study cohorts. The area under the curve of AFP ratio was 0.743. The area under the curve of DCP ratio was 0.695. The cut-off values of AFP and DCP ratios were 1.3 and 1.0, respectively. In the validation cohort, the accuracy of the prediction of response in this validation cohort (71.4%) showed no significant difference compared to that in the study cohort (72.4%) (p = 1.0). The results suggested that patients with a high tumor marker ratio could be switched to alternative therapeutic regimens despite the SD response to HAIC.

Background In patients with advanced hepatocellular carcinoma (HCC), evidence is unclear as to whether hepatic arterial infusion chemotherapy (HAIC) or sorafenib is superior. We performed a prospective, open-label, non-comparative phase II study to assess survival with HAIC or HAIC converted to sorafenib. Methods Fifty-five patients were prospectively enrolled. Patients received HAIC as a second course if they had complete response, partial response, or stable disease (SD) with an alpha fetoprotein (AFP) ratio 1 and a DCP ratio > 1 or disease progression. The primary endpoint was the 1-year survival rate. Secondary endpoints were the 2-year survival rate, HAIC response, survival rate among HAIC responders, progression-free survival, and adverse events. Results Of the 55 patients in the intent-to-treat population, the 1-year and 2-year survival rates were 64.0 and 48.3%, respectively. After the first course of HAIC, one (1.8%) patient showed complete response, 13 (23.6%) showed partial response, 30 (54.5%) had SD, and 10 (18.1%) patients had progressive disease. Twenty-three patients (41.8%) had SD with AFP ratios 1 and DCP ratios > 1. Thirty-seven patients (68.5%) were responders and 17 (30.9%) were non-responders to HAIC. In responders, the 1-year and 2-year survival rates were 78 and 62%, respectively. Conclusion Given the results of this study, this protocol deserves consideration for patients with advanced HCC. This trial was registered prospectively from December 12. 2012 to September 1. 2016.

The aim of this study was to determine the risk factors for worsening of gastroesophageal varices (GEVs) and development of portosystemic encephalopathy in patients with hepatitis B virus (HBV)-related cirrhosis during nucleos(t)ide analog (NA) treatment.One hundred and thirty-seven patients with HBV-related cirrhosis were enrolled in this retrospective cohort study. Findings of portal hemodynamics with computed tomography, liver function, and endoscopic examinations during NA treatment were assessed.Among 137 patients, feeding vessels for GEVs (left gastric vein, posterior gastric vein, and short gastric vein) were present in 56 (41%) patients, and extrahepatic portosystemic shunt (paraesophageal vein, paraumbilicul vein, and splenorenal shunt) were present in 36 (26%) patients at the start of NA treatment. Although NA treatment was successful, significant improvements were not observed in portosystemic collateral vessels 3 years after NA treatment and GEVs were exacerbated in 48 (35%) patients. The cumulative 5- and 10-year exacerbation rate of GEVs was 27% and 50%, respectively. By multivariate analysis, the existence of feeding vessels for GEVs at the start of NA treatment was the independent predictive factor for the exacerbation of GEVs (P 0.001). Eight patients who had extrahepatic portosystemic shunt at the start of NA treatment developed portosystemic encephalopathy during follow-up. The 3- and 5-year incidence of that was 5% and 8%, respectively.The presence of portosystemic collateral vessels at the start of NA treatment increases the risk of GEVs worsening and development of portosystemic encephalopathy in patients with HBV-related cirrhosis, despite improvement of liver function and success in reducing viral loads with NA treatment.

The relationship between the presence of villous edema (VE) in portal hypertensive enteropathy and clinical factors remains unclear. The aim of this study was to reveal the clinical factors related to VE in patients with liver cirrhosis (LC), and investigate the clinical significance of VE.Between February 2009 and September 2016, 363 consecutive patients with LC underwent capsule endoscopy for diagnosing portal hypertensive enteropathy at Hiroshima University Hospital. We evaluated the relationship between the presence of VE and patients' clinical characteristics, findings of esophagogastroduodenoscopy and computed tomography, and survival time.Villous edema was observed in 131 patients (36%), and severe lesions were found in 71 (20%). The presence of VE was significantly greater in patients with Child-Pugh classification B or C, esophageal varices, portal hypertensive gastropathy (PHG), ascites, portal vein thrombosis (PVT), and splenomegaly. In multivariate analysis, Child-Pugh class B or C, esophageal varices, PVT, and splenomegaly were significant predictive factors for the presence of VE. Severe VE was significantly greater in patients with Child-Pugh class B or C, serum albumin level ≤ 3.2 mg/dL, PHG, and PVT. In multivariate analysis, PHG, Child-Pugh class B or C, PVT, were significant predictive factors for severe VE.Clinical factors related to portal hypertension were significantly correlated with VE. In particular PVT was correlated with the appearance and exacerbation of VE. Periodic capsule endoscopy in LC patients may lead to early detection of portal hypertension and PVT.

To evaluate the safety and efficacy of stereotactic body radiotherapy (SBRT) for the treatment of hepatocellular carcinoma (HCC) in elderly patients.From 2008 to 2015, 117 patients with HCC (≤3 nodules, ≤30 mm in diameter, Child-Pugh score ≤7, and no vascular or extracellular metastasis) were treated with SBRT at our hospital. We evaluated overall survival (OS), disease-free survival (DFS), local control, and adverse events. Patients were stratified according to age 75 years and older (elderly group, n = 54) and age younger than 75 years (young group, n = 63).The median OS in the elderly group was not significantly different from that in the young group (52 months vs. not reached, P = 0.27). The 1-, 2-, and 3-year OS rates were 96.2%, 77.6%, and 63.9%, respectively, in the elderly group, and 96.8%, 84.8%, and 67.7%, respectively, in the young group. The median DFS in the elderly group was significantly shorter than that in the young group (13 vs. 25 months, respectively; P = 0.03). The 1-, 2-, and 3-year DFS rates were 50.6%, 30.4%, and 26.6%, respectively, in the elderly group and 66.5%, 50.7%, and 45.3%, respectively, in the young group. The 3-year local tumor control rate in the elderly group was 98.1%, and that in the young group was 98.4% (P = 0.83). There was no difference between groups in the incidence of any adverse events.Stereotactic body radiotherapy can be effective and safe for the treatment of HCC in elderly patients.

The risk of hepatocellular carcinoma (HCC) development is reduced following viral elimination by interferon therapy in chronic hepatitis C patients. However, the risk in patients treated with interferon-free direct-acting antivirals (DAAs) is unknown. We evaluated chronic hepatitis C patients who achieved viral eradication by pegylated-interferon plus ribavirin (PEG-IFN/RBV, n = 244) or daclatasvir plus asunaprevir (DCV/ASV, n = 154) therapy. None of the patients had prior history of HCC or antiviral therapy. The median observation period after the end of treatment for the PEG-IFN/RBV and DCV/ASV groups were 96 (range 10-196) and 23 (range 4-78) months, respectively. During the observation period, HCC developed in 13 (5.3%) and 7 (4.5%) patients in the PEG-IFN/RBV and DCV/ASV groups, respectively. The cumulative HCC development rate after 1-, 3- and 5-years (0.4%, 3% and 5% for the PEG-IFN/RBV group and 0.6%, 9% and 9% for the DAA group, respectively) were similar between the two groups. Propensity score matching analysis also showed no significant difference in HCC development rates between the two groups. Serum AFP levels decreased to similar levels between PEG-IFN/RBV and DCV/ASV groups following the achievement of viral eradication. The risk for HCC development following viral eradication by IFN-free DAA therapy may be similar to that in IFN-based therapy.

Combination of sofosbuvir plus ledipasvir therapy has been expected to enhance sustained virological response (SVR) rates in hepatitis C virus (HCV) genotype 1 chronic infected patients. We analyzed the emergence of drug resistance-associated variants (RAVs) in treatment failure and changes in lipid profiles in sofosbuvir/ledipasvir-treated patients. A total of 176 patients with chronic HCV genotype 1 infection without decompensated liver cirrhosis were treated with sofosbuvir/ledipasvir for 12 weeks. NS5A and NS5B RAVs were determined by either Invader assay or direct sequencing. Serum lipid-related markers were measured at the start of treatment and at week 4 in patients who received sofosbuvir/ledipasvir and ombitasvir/paritaprevir/ritonavir therapies. SVR was achieved in 94.9% (167 out of 176) of patients. SVR12 rate was 97.1% for patietns with low frequncy (25%) of baseline NS5A RAVs, but 82.8% for patients with high frequency (75%) of NS5A RAVs. In multivariate regression analysis, higher albumin (odds ratio [OR] = 0.020 for presence; P = 0.007), and NS5A-L31/Y93 RAVs with a population frequency75% (OR = 29.860 for presence; P = 0.023) were identified as significant independent predictors for SVR12. NS5A-Y93H substitutions were detected in all nine treatment failures at HCV relapse, and three out of six patients with NS5A inhibitor-naïve patients achieved additional NS5A RAVs. Serum low-density lipoprotein cholesterol and apolipoprotein B levels were significantly elevated at week 4 in sofosbuvir/ledipasvir-treated patients. These elevations were greater than in ombitasvir/paritaprevir/ritonavir-treated patients. In conclusion, NS5A multi-RAVs are likely to develop in patients who fail to respond to sofosbuvir/ledipasvir therapy. Inhibition of HCV replication with sofosbuvir might affect lipid metabolism.

Wisteria floribunda agglutinin positive human Mac-2-binding protein glycosylation isomer (M2BPGi) is a novel serum glycomarker for liver fibrosis. However, it is not known whether or not M2BPGi reflects only liver fibrosis. We measured serum M2BPGi levels in patients with acute liver injury.Fifty-one patients with acute liver injury were enrolled. M2BPGi levels were measured at the initial visit and at achievement of recovery. The relationship between M2BPGi values at the initial visit and clinical outcomes was analyzed.Serum M2BPGi levels at the initial visit were elevated in 47 of 51 acute liver injury patients (8.33 ± 7.56 cutoff index). M2BPGi values were associated with prothrombin activity (r = -0.600, P = 0.001), total bilirubin level (r = 0.588, P = 0.001), and Model for End-Stage Liver Disease score (r = 0.490, P = 0.001) but not with aspartate aminotransferase (r = -0.070) and alanine aminotransferase (r = -0.073) levels. M2BPGi values at the initial visit were significantly higher in patients with acute liver failure (diagnosed by prothrombin activity of 40% or less; P 0.001), subsequent development of hepatic coma (P = 0.036), and subsequent requirement of liver transplant (P = 0.014), and in a patient who died (P = 0.045). M2BPGi values decreased after aminotransferase level normalization in patients who recovered from acute liver injury; however, M2BPGi level was not a predictive factor for recovery with medical therapy.Serum M2BPGi values increased in patients with acute liver injury and decreased following recovery. The marker seems to reflect not only liver fibrosis but also other factors, such as liver inflammation, liver damage, and hepatocyte regeneration.

Aim The predictive value of the recently identified interferon-λ (IFNL)4 polymorphism on the outcome of telaprevir (TVR), pegylated interferon (PEG IFN) plus ribavirin (RBV) combination therapy for chronic hepatitis C is unknown. Methods We assessed predictive factors for sustained virological response (SVR) for TVR, PEG IFN plus RBV combination therapy in 283 genotype 1 chronic hepatitis C patients. IFNL4 polymorphism ss469415590 was analyzed by Invader assay. Results SVR rates for patients with IFNL4 TT/TT genotype were significantly higher than for those with the IFNL4 TT/ΔG or ΔG/ΔG genotypes (93% and 59%, respectively, P

Background The aim of this study was to evaluate the birth and discharge dates of neonates and analyze their distribution over days of the week and the old lunar calendar. Methods A retrospective study of the neonates discharged in the years 1990, 2000, 2005, and 2010 was conducted in a general hospital in Tokyo, Japan. Data are represented as odds ratios (OR) of the total number of discharges per day divided by the expected number of days per year, for each day of the week as well as each 6 day cycle of the lunar calendar. Results The timing of discharge has an uneven distribution across the days of the week, with weekday discharge rates significantly lower than weekend discharge rates. This uneven distribution is particularly significant in the preterm subgroup. In contrast, there is a minor uneven distribution of births across the days of the week and that of discharges across the 6 day cycle of the lunar calendar. Logistic regression analysis for 2005 and 2010 identified admission fee paid by insurance and prematurity as significant factors associated with weekend/holiday discharge (OR, 1.84; 95% confidence interval [CI]: 1.23–2.75; OR, 1.71; 95%CI: 1.15–2.55, respectively). The average length of stay of neonates discharged on the weekend was longer than that for those discharged on a weekday, in both term and preterm infants. Conclusions Japanese parents prefer the convenience of weekends over old superstitions about using the lunar calendar to determine the discharge date.

To compare the efficacy and safety of edoxaban and warfarin for treatment of portal vein thrombosis (PVT) following danaparoid sodium in patients with liver cirrhosis.Fifty cirrhotic patients with PVT treated initially for 2 weeks with danaparoid sodium were enrolled in this retrospective cohort study. Treatment was later switched to either edoxaban (n = 20) or warfarin (n = 30). We compared the efficacy and safety of edoxaban and warfarin for up to 6 months. The PVT volume was measured by dynamic computed tomography before treatment, at 2 weeks, and at 1, 3, and 6 months.There were no significant differences in the clinical characteristics of patients in the two groups. Treatment with edoxaban reduced the volume of PVT from 1.42 cmEdoxaban following danaparoid sodium is an effective anticoagulant and could be potentially considered as one of the treatment options for PVT in cirrhotic patients.

Older patients with chronic hepatitis C have a lower virological response to interferon (IFN) treatment compared to younger patients. The efficacy of telaprevir (TVR) and PEG-IFN plus ribavirin combination therapy and the predictive value of recently identified IFN lambda (IFNL) 4 polymorphisms on the outcome of therapy for older patients have not been addressed.We assessed predictive factors for sustained virological response (SVR) to triple therapy in 226 younger (≤65 years) and 87 older (65 years) Japanese patients with chronic genotype 1 hepatitis C. IFNL4 polymorphism ss469415590 was analyzed by Invader assay.The SVR rate for older patients was slightly lower than for younger patients (69 vs. 82%, P = 0.043). In the older group, the SVR rate for patients with the IFNL4 TT/TT genotype was significantly higher than patients with TT/ΔG or ΔG/ΔG genotypes (81.8 and 42.9%, P = 0.003). In multivariate regression analysis, rapid virological response (OR 36.601, P = 0.002) and IFNL4 TT/TT genotype (OR 19.502, P = 0.009) were identified as significant independent predictors for SVR in older patients. Treatment-related decreases in hemoglobin and increases in serum creatinine were higher in older patients than younger patients. Reduction of initial TVR dose to 1,500 mg per day alleviated these adverse events without compromising SVR rate in older patients.Analysis of IFNL4 polymorphisms is a valuable predictor in older patients receiving TVR triple therapy. 1,500 mg per day is a suitable initial TVR dose for older Japanese patients.

Background Delay of umbilical cord clamping by at least 1 min is recommended for newborns not requiring resuscitation in the International Liaison Committee On Resuscitation–Consensus on Science with Treatment Recommendations (ILCOR-CoSTR) 2010 guidelines. The delay in clamping improves iron status through early infancy but may increase the likelihood of jaundice requiring phototherapy. The present study investigated the relationship between umbilical cord hemoglobin and the rate of jaundice requiring phototherapy in healthy Japanese newborns. Methods Cord hemoglobin was measured in healthy newborns and the rate of infants receiving phototherapy for jaundice and other data were obtained from medical records. Results Jaundice requiring phototherapy mostly occurred in association with high cord blood hemoglobin, which is increased by delayed cord clamping. Conclusions Higher cord hemoglobin may increase neonatal jaundice in newborns in Japan, therefore the present results support the Japan Resuscitation Council guideline 2010, which does not recommend delay of umbilical cord clamping by at least 1 min, in contrast to the ILCOR guidelines.

Aim Acoustic radiation force impulse (ARFI) technology, involving the shear wave velocity (SWV) with virtual touch tissue quantification (VTTQ), are currently available for the assessment of liver fibrosis, while there is no index derived from the combination of SWV and blood tests. The aim of this study was to develop a new index for assessment of liver fibrosis. Methods The subjects were 176 consecutive patients with hepatitis C (training set [n = 120] and validation set [n = 56]) who underwent liver biopsy in our institution. Results In the training set, SWV, international normalized ratio (INR) and alanine aminotransferase (ALT) correlated independently and significantly with fibrosis. According to this, we developed the VIA index = −1.282 + 0.965 × SWV + 1.785 INR + 0.00185 ALT. The areas under the receiver–operator curve (AUROC) of the VIA index were 0.838 for the diagnosis of significant fibrosis (≥F2), 0.904 for the severe fibrosis (≥F3) and 0.958 for the cirrhosis (F4) in the training set. While in the validation set, AUROC of the VIA index were 0.917 for F2 or higher, 0.906 for F3 or higher and 1.000 for F4, respectively. AUROC of the VIA index was improved compared to SWV alone, equivalent for VIA for the diagnosis of F2 or higher, and superior to that of FIB-4 index and aspartate aminotransferase-to-platelet ratio index for the diagnosis of F3 or higher and F4. Conclusion The VIA index is potentially more useful for assessment of liver fibrosis than SWV alone, and easily and accurately measures liver fibrosis stage.

Aim Steatosis is a common histological feature of chronic liver disease, especially alcoholic and non-alcoholic fatty liver disease, as well as chronic hepatitis C. A recent study showed that evaluating the controlled attenuation parameter (CAP) with transient elastography was an efficient way of non-invasively determining the severity of hepatic steatosis. The objective of this study was to prospectively evaluate the utility of CAP for diagnosing steatosis in patients with chronic liver disease. Methods One hundred and fifty-five consecutive patients with suspected chronic liver disease underwent steatosis diagnosis using CAP, blood sample analyses, computed tomography for assessing the liver/spleen ratio and liver biopsy. Steatosis was graded according to the percentage of fat-containing hepatocytes: S0, less than 5%; S1, 5–33%; S2, 34–66%; and S3: more than 66%. Results The CAP was significantly correlated with steatosis grade, and there were significant differences between the CAP value of the S0 patients and those of the patients with other grades of steatosis. S0 and S1–3 hepatic steatosis were considered to represent mild and significant steatosis, respectively. The CAP values of the patients with mild and significant steatosis were significantly different (P

AbstactBackground and Aims To compare the tumor control and safety of stereotactic body radiation therapy (SBRT) combined with transcatheter arterial chemoembolization (TACE) for small, solitary, and hypervascular hepatocellular carcinoma (HCC) with TACE alone. Methods Three hundred and sixty-five HCC patients who had solitary, ≤ 3 cm, and hypervascular nodule were treated with TACE. Among them, 30 patients followed by SBRT (SBRT group) and 38 patients without additional therapy and previous HCC treatment (control group) were enrolled in this retrospective cohort study. Local tumor progression, complication, and disease-free survival were compared between these groups. Results There was no difference in clinical background between these groups. Complete response to therapy was noted in 29 (96.3%) patients of the SBRT group, and in only one (3.3%) patient of the TACE group (P

Chronic hepatitis C virus (HCV) infection is associated with renal dysfunction. Daclatasvir and asunaprevir combination therapy showed a high virological response for genotype 1 chronic HCV-infected patients with renal dysfunction on hemodialysis. However, the safety and efficacy of the therapy for patients with renal dysfunction who are not on hemodialysis are not well-known. In total, 147 patients with chronic HCV genotype 1 infection were treated with 24 weeks of daclatasvir plus asunaprevir therapy. Among these patients, 126 had normal renal function (estimated glomerular filtration rate [eGFR] ≥ 50 ml/min/1.73 m2) and 21 had renal dysfunction (eGFR

Biomarkers predicting the response to the anticancer treatment and prognosis in patients with advanced hepatocellular carcinoma (HCC) are required. Recently, high mobility group box 1 (HMGB1) was reported to promote HCC progression and be associated with poor prognosis for patients with HCC. The purpose of this study was to assess serum HMGB1 concentrations before and during sorafenib treatment or hepatic arterial infusion chemotherapy (HAIC) and to explore the ability of serum HMGB1 concentrations to predict prognosis. Serum HMGB1 concentrations were measured in 71 and 72 patients with advanced HCC treated with sorafenib and HAIC, respectively, to assess their usefulness for prediction of the response to the treatment and prognosis. Multivariate analysis identified high HMGB1 at 4 weeks (P = 0.001), high α-fetoprotein (AFP) at baseline (P = 0.025), tumor liver occupying rate (P = 0.009) and modified RECIST (mRECIST, P

Daclatasvir and asunaprevir combination therapy has shown a high virological response for chronic genotype 1 hepatitis C virus (HCV) infected-patients. However, the real-world efficacy and safety of the therapy for patients with cirrhosis are unknown.A total of 252 patients with genotype 1 HCV infection (158 with chronic hepatitis and 94 with compensated liver cirrhosis) were treated with 24 weeks of daclatasvir and asunaprevir combination therapy. Plasma concentrations of daclatasvir and asunaprevir at day 5 of treatment, end-of-treatment response, sustained virological response (SVR), and the frequencies of adverse events were analyzed.Plasma asunaprevir concentration was significantly higher, and daclatasvir concentration tended to be higher, in cirrhosis patients compared with chronic hepatitis patients. End-of-treatment response was achieved in 95.6% and 94.7% of chronic hepatitis and cirrhosis patients, respectively, and SVR was achieved in 94.3% and 92.6%. Although pre-treatment NS5A drug resistant-associated variants were detected, a high SVR rate was achieved when the population frequency of the variant was low. The frequencies of treatment-related adverse events in cirrhosis patients were similar to those in chronic hepatitis patients. Treatment discontinuation due to adverse events occurred in three and two patients in chronic hepatitis and cirrhosis groups, respectively; however, four out of five patients with treatment discontinuation nonetheless achieved SVR.Patients with compensated liver cirrhosis have similar virological response and tolerance for daclatasvir plus asunaprevir therapy to patients with chronic hepatitis. This combination therapy might offer a safe and effective treatment for chronic HCV infected-patients with compensated cirrhosis.

Daclatasvir and asunaprevir combination therapy has shown a high virological response for chronic genotype 1 hepatitis C virus (HCV)-infected patients. However, the safety and efficacy of the therapy for older patients are unknown. One hundred seventy patients younger than 75 years and 139 patients aged 75 years or older with genotype 1 HCV infection were treated for 24 weeks with daclatasvir plus asunaprevir. Pretreatment drug-resistance-associated variants at NS5A-L31 and NS5A-Y93 were determined by the Invader assay. Virological response and adverse events according to age were analyzed. The sustained virological response (SVR) rate for older patients was similar to that for younger patients (97.1 and 92.4 % respectively). In multivariate regression analysis, prior simeprevir treatment (odds ratio 56.6 for absence; P
