Abstract
Background: Glycoprotein non-metastatic melanoma protein B (GPNMB) is expressed in macrophages during recovery from acute liver injury (ALI) in carbon tetrachloride (CCl4)-induced liver injury model mice. In this retrospective study, we assessed whether GPNMB levels in the serum and injured liver correlate with liver injury severity and prognosis in patients with ALI or acute liver failure (ALF). Methods: The study involved 56 patients with ALI or ALF who visited the Kagoshima University Hospital. Serum GPNMB level was measured over time, and the localization, proportion, origin, and phenotype of GPNMB-expressing cells in the injured liver were assessed. Finally, the phenotypes of human monocyte-derived macrophages and peripheral blood mononuclear cells (PBMCs) of patients with ALI and ALF were analyzed. Results: Peak GPNMB levels were significantly higher in patients with ALF and hepatic encephalopathy (HE), as well as in those who underwent liver transplantation or died, than in others. The peak GPNMB level correlated with prothrombin activity, prothrombin time-international normalized ratio, Model for End-stage Liver Disease score, and serum hepatocyte growth factor level. GPNMB was expressed in CD68-positive macrophages, and its level increased with the severity of liver injury. The macrophages showed the same polarization as M2c macrophages induced with interleukin-10 from human monocytes. Moreover, PBMCs from patients with ALF exhibited an immunosuppressive phenotype. Conclusion: We found that GPNMB levels in the serum and injured liver, which increased in patients with ALF, especially in those with HE, correlated with the severity of liver injury and prognosis of ALI and ALF. Moreover, GPNMB-positive macrophages exhibited the M2c phenotype. Our results indicate that persistently high GPNMB levels may be a prognostic marker in patients with ALI and ALF.

Abstract
The present study clarified the prognosis of intermediate-stage hepatocellular carcinoma (HCC) patients who received lenvatinib (LEN) followed by transcatheter arterial chemoembolization (TACE) on demand. We retrospectively evaluated 88 intermediate-stage HCC patients who received LEN. The median age was 74 (range: 47-92) years old, 67 patients were male, and 82 were classified as Child-Pugh A. LEN was administered until disease progression or discontinuation due to adverse events (AEs). The mean duration of LEN treatment was 7.0 months. The response and disease control rates were 51.1% and 89.8%, respectively. The median progression-free survival and overall survival (OS) after the initiation of LEN were 6.8 months and 29.9 months, respectively. The OS in patients for whom LEN was re-administered after TACE (TACE-LEN) was better than that in patients who received other therapies (e.g., only TACE, TACE-other therapy, or only other therapy) even with propensity score matching (p = 0.008). A Cox proportional hazard analysis showed that TACE-LEN was most strongly associated with the OS (hazard ratio: 0.083, 95% confidence interval: 0.019-0.362, p = 0.001). LEN was administered for approximately 11.1 months after TACE. In intermediate-stage HCC patients who can tolerate LEN without discontinuation due to AEs, TACE-LEN may prolong the prognosis.

Abstract
We treated a case of gastroesophageal varices due to decompensated liver cirrhosis associated with Wilson's disease. The varicose veins penetrated the paraesophageal vein. We performed endoscopic variceal ligation (EVL) on the perforating vein and endoscopic injection sclerotherapy (EIS) distally. However, 5 days after treatment, the patient vomited blood. Esophagogastroduodenoscopy showed bleeding from the ulcer after EVL at the perforating vein. We performed EVL and stopped the bleeding. However, the next day, she vomited blood again and developed hemorrhagic shock. We were able to achieve hemostasis and save the patient's life with combination therapy consisting of percutaneous transhepatic obliteration and Sengstaken-Blakemore tube placement.

Abstract
Background The features of hepatitis C virus patients with a sustained virologic response (SVR) who developed hepatocellular carcinoma (HCC) after direct-acting antiviral (DAA) therapy are unclear. Methods The study population included 1494 DAA-SVR patients without a history of HCC. The cumulative carcinogenesis rate after the end of treatment (EOT) and factors related to HCC were analyzed. Results Sixty (4.0%) patients developed HCC during a median observation period of 47.6 months. At four years, the cumulative carcinogenesis rate was 4.7%. A Cox proportional hazards analysis showed that age ≥73 years (hazard ratio [HR]: 2.148), male sex (HR: 3.060), hyaluronic acid (HA) ≥75 ng/mL (HR: 3.996), alpha-fetoprotein at EOT (EOT-AFP) ≥5.3 ng/mL (HR: 4.773), and albumin at EOT (EOT-Alb) <3.9 g/dL (HR: 2.305) were associated with HCC development. Especially, EOT-AFP ≥5.3 ng/mL was associated with HCC development after 3 years from EOT (HR: 6.237). Among patients who developed HCC, AFP did not increase in patients with EOT-AFP <5.3 ng/mL at the onset of HCC. Of these 5 factors, EOT-AFP ≥5.3 ng/mL was scored as 2 points; the others were scored as 1 point. The 4-year cumulative carcinogenesis rate for patients with total scores of 0–2, 3–4, and 5–6 points were 0.6%, 11.9%, and 27.1%, respectively (p<0.001). Conclusions EOT-AFP ≥5.3 ng/mL is useful for predicting HCC development after an SVR. However, AFP does not increase in patients with EOT-AFP <5.3 ng/mL at the onset of HCC. The combination of EOT-AFP, age, sex, HA, and EOT-Alb is important for predicting carcinogenesis.

Abstract
The prevalence of non-alcoholic fatty liver disease (NAFLD) is continuously increasing, with the proportion of patients with liver carcinogenesis due to non-alcoholic steatohepatitis (NASH) rising accordingly. Although it is important to identify individuals with hepatic carcinogenesis among patients with NAFLD, useful biomarkers have not yet been established. Previously, in a mouse model of diabetes mellitus without genetic modifications, we reported that a high-fat diet increases serine palmitoyltransferase long chain subunit 3 (SPTLC3) expression in liver tissue, accompanied by high frequency of liver carcinogenesis. Serine palmitoyltransferase (SPT) catalyzes the metabolism of fatty acids, particularly sphingolipid synthesis, and SPTLC3 has been identified as its catalytic subunit, but its role in liver disease is unclear. In the present study, the importance of SPTLC3 in NAFLD development was investigated. SPTLC3 mRNA expression was observed in a liver cancer cell line and in liver tissues from patients with NAFLD and liver cancer. In total, 99 patients with NAFLD (66 without hepatocellular carcinoma (HCC) and 33 with HCC were recruited, having been diagnosed by liver biopsy or imaging, along with 6 healthy volunteers (HVs). Serum was collected from patients and HVs, and SPTLC3 level was assessed by ELISA. SPTLC3 expression was higher in non-cancerous compared with that in cancerous liver tissues. Serum SPTLC3 levels were negatively correlated with platelet count and positively correlated with hyaluronic acid levels, suggesting an association with liver fibrosis. Moreover, SPTLC3 levels were significantly higher in the HCC group than in the HV and NAFLD groups. Multivariate analysis of HCC-related factors identified platelets, alanine transferase, albumin and SPTLC3 as independent factors associated with HCC. Furthermore, in patients with other chronic liver diseases (hepatitis B and C, and alcoholic liver disease), no significant differences in serum SPTLC3 levels were observed between patients with or without HCC. Thus, SPTLC3 expression increases specifically with the progression of NAFLD. Overall, the present results indicate that SPTLC3 may be involved in the development of liver carcinogenesis during NAFLD.

Abstract
Highly sensitive Lens culinaris agglutinin-reactive fraction of α-fetoprotein (hs-AFP-L3) is a specific marker for hepatocellular carcinoma (HCC) and has been reliable in cases with a low serum α-fetoprotein (AFP) level. However, the biomarkers that contribute to hepatocarcinogenesis during the long-term observation are not yet clear. The present study reported the clinical utility of hs-AFP-L3 in the long-term observation of patients with chronic liver disease. The subjects were 106 patients with chronic liver disease without HCC or a history of HCC treatment and who had been followed for >12 months. hs-AFP-L3 was measured using cryopreserved serum. The factors contributing to hepatocarcinogenesis were examined using univariate and multivariate analyses. The median observation period was 88 months (15-132 months). The cumulative incidence of HCC was 10.5% at 5 years and 19.6% at 10 years. The univariate analysis revealed that age ≥55 years old, platelet count ≤13.1x104/µl, hyaluronic acid ≥80.8 ng/ml, alanine transaminase ≥47 U/l, AFP ≥6.3 ng/ml, hs-AFP-L3 ≥3.5% and des-γ-carboxy prothrombin (DCP) ≥25 mAU/ml were significant factors. In the multivariate analysis, platelet count ≤13.1x104/µl [hazard ratio (HR), 4.966; 95% confidence interval (CI), 1.597-15.437; P=0.006] and hs-AFP-L3 ≥3.5% (HR, 5.450; 95% CI, 1.522-19.512; P=0.009) were extracted as significant factors contributing to hepatocarcinogenesis. In addition, for cases with AFP <20 ng/ml, a multivariate analysis revealed that hs-AFP-L3 ≥4.9% (HR, 11.608; 95% CI, 2.422-55.629; P=0.002) and DCP ≥25 mAU/ml (HR, 3.936; 95% CI, 1.088-14.231; P=0.037) were significant factors contributing to hepatocarcinogenesis. hs-AFP-L3 is a useful marker for predicting hepatocarcinogenesis in the long-term observation of patients with chronic liver disease.

Abstract
Background
The assessment of residual peri-device leaks (PDL) after percutaneous left atrial appendage closure (LAAC) remains crucial in the post-procedural management. Clinical significance of PDL is still poorly understood and echocardiographic recognition of PDL remains challenging. This study aimed to verify a novel proposed echocardiographic classification for prediction of clinically significant PDL following LAAC.

We retrospectively evaluated our echocardiographic data of 72 patients who underwent percutaneous LAAC at the University Hospital Jena between September 2015 - 2018. All echo images were transferred to a workstation for offline analysis by two independent investigators. Total number of studies was 127. We proposed a morphological classification of LAA devices (Fig. 1A-C) based on the amount of echodensity and luceny inside the devices into three types: type A: homogenous echodensity in 0, 45, 90 and 135°; indicating completely thrombosed device, type B with inhomogeneous echo-lucencies (<50% of device) and type C: partially thrombosed device with echo-lucencies >50% of total, which we labeled “ice-cream cone” sign. Each type was then matched to the degree of PDL and other clinical and paraclinical parameters.
Results
Tab.1 shows patient's characteristics. PDL was found in 21% of patients. Four patients showed regression of PDL after 160 days. Patients with type C had the most percentage of PDL in three types at 6 months follow-up (type A: 7%, type B: 33%, type C 100%, p<0.001). Device size in patients with type C was largest in three types (type A: 25.9±3.6mm, type B: 25.8±3.4mm, type C 29.8±3.0mm, type A vs. B, p=0.018; type B vs. C, p=0.007). Mean compression rate after 45 days was 21±9.3% in type A vs. 14±7.4% in type C (p=0.022). Ice cream sign showed a sensitivity of 53.1%, specificity of 100% and positive predictive value of 100% for prediction of PDL.
Conclusion
Our data demonstrate that: 1) This novel classification irrespective of anticoagulation regimen, can accurately discriminate among various degrees of PDL, in such that type C or “ice cream sign” has a very high positive predictive value for PDL (100%). 2) Type A, the ideal type, is associated with smaller landing zones and a higher compression rate.

Abstract
Introduction
Echocardiographic detection of residual peri-device leakage (PDL) after percutaneous left atrial appendage closure (LAAC) remains crucial. Significance of PDL and cardiac tissue remodeling after LAAC are still poorly understood but might have diagnostic implications. This study aims to characterize and verify if a novel echocardiographic classification system to asses the success of LAAC in combination with quantifiable biomarkers of cardiovascular tissue remodeling can help in the prediction of PDL.
Methods
Patients eligible for LAAC were included. Serum levels of the cardiac remodeling marker Galectin-3 were determined before device implantation (baseline), 45 days (45d) and 6 months (6M) after LAAC using ELISAs. Transesophageal echocardiography (TEE) was carried out to assess success of the LAAC procedure. All echo images were retrospectively evaluated by two independent investigators. Based on the amount of echodensity and luceny inside the devices after LAAC, three types can be distinguished that grade the degree of closure of the LAA. Type A has complete homogenous echodensity in 0, 45, 90 and 135°, indicating completely thrombosed device. Type B shows inhomogeneous echo-lucencies (<50% of device). Type C describes a partially thrombosed device with echo-lucencies >50%. Novel classification according to Hamadanchi, Jena, Germany (Fig. 1).
Results
We included 44 patients (characteristics listed in Table 1). Complete LAAC (without any residual flow) was achieved in 64% (28 patients) after 45 days and in 80% (35 patients) after 6 months. Mean PDL diameter was 3.5±1.5mm. Type A showed the lowest rate of PDL after 45d (Type A: 22% vs. Type B: 33% vs. Type C: 88%; p=0.007) and after 6M (Type A: 12% vs. Type B: 28% vs. Type C: 100%; p=0.002). Galectin-3 levels did not show a relevant difference regarding the type of AF at baseline (paroxysmal AF: 11.7±5.4 ng/ml vs. permanent AF: 12.1±6.3 ng/ml; p=0.45). We observed a significant increase and distribution of serum levels of Galectin-3 [ng/ml] after 45 days among the three types (Baseline: 13.1±5.8; 45d: 16.3±7.2 (Type A) vs. 19.2±8.6 (Type B) vs. 25.8±9.4 (Type C); p=0.031) followed after 6 months by a drop of Galectin-3 for type A and B toward and below baseline levels (6M: 8.9±3.1 (Type A) vs. 12.4±5.5 (Type B)) whereas type C persisted in showing elevated Galectin-3 levels compared to all other types (6M: 17.5±4.5 (Type C); p<0.001), Fig. 2. Correlation analysis shows a significant negative correlation trend between Galectin-3 and mean PDL diameter (−0.51; p=0.016) after 45 days and a relevant positive correlation after 6 months (0.58; p=0.017).
Conclusion
After LAAC, Galectin-3 levels are elevated, as a marker of myocardial fibrosis in the LAA. Depending on the degree of closure of the LAA, Galectin-3 decreases to the baseline level or stays elevated in case of relevant PDL and could therefore be considered as a new biomarker for closure success.

Abstract
Abstract
Introduction
Left atrial cardiac tissue remodeling following left atrial appendage closure (LAAC) is a scientifically neglected phenomenon until now but might have impact on functional outcome of patients suffering from atrial fibrillation (AF). Thus, our study is focused on quantification of key biomarkers reflecting fibrosis development as a major component within cardiovascular tissue remodeling.
Methods
Patients (CHA2DS2VASC score ≥1, HASBLED score ≥3) with bleeding complications under anticoagulation therapy and therefore eligible for LAAC were included in the present study. Serum levels of biomarkers of cardiac fibrosis and remodeling (Galectin-3, ST2/IL-2, ST2/IL-1, B domain containing Tenascin-C (B+ Tn-C), C domain containing Tenascin- C (C+ Tn-C)) were determined before device implantation (baseline), 45 days (45d) and 6 months (6M) after LAAC using commercially available ELISAs. To quantify functional outcome, all patients performed a 6-minutes walk test (6- MWT). Transesophageal echocardiography (TEE) was carried out to assess success of the LAAC procedure regarding peri-device leakage (PDL).
Results
We included 33 patients (age: 73.5±6.7 years; 21 men (64%) and 12 women (36%); BMI: 29.1±5.1 kg/m2; CHA2DS2VASC score: 4.2±1.2; left ventricular ejection fraction: 61.1±9.3%; mean occluder size: 25.9±3.9 mm; type of AF: 46% paroxysmal (15 patients), 55% permanent (18 patients)). Complete LAAC (without any residual low) was achieved in 60% (19 patients) after 45 days and in 87% (29 patients) after 6 months. At baseline, Galectin-3 levels did not show a relevant difference regarding the type of AF (paroxysmal AF: 14.7±5.4 ng/ml vs. permanent AF: 13.1±6.3 ng/ml; p=0.45). We observed a significant increase of serum levels of Galectin-3 [ng/ml] after 45 days vs. baseline (baseline: 13.3±5.8 vs. 45d: 18.3±10.6; p=0.005) with a return to baseline levels after 6 months (baseline: 13.3±5.8 vs. 6M: 12.5±5.4; p=0.28). Compared to patients with successful LAAC, patients with PDL had a trend towards higher levels of Galectin-3 after 6 months (11.3±5.5 ng/ml vs. 16.1±4.1 ng/ml, p=0.09). Measurements of other fibrosis markers were statistically not significantly different. The walking distance measured by the 6-MWT increased significantly from 298.5±89.5 meters at baseline to 335.5±95.1 meters (p=0.04) after 45d and remained significantly elevated after 6M (346.7±122.7 meters; p=0.02).
Conclusion
The implantation of an LAA occluder device is accompanied by significantly increased circulating levels of the fibrosis biomarker Galectin-3 after 45 days in patients with AF. The regression in serum levels after 6 months probably reflects a successful fibrotic remodeling in the left atrial appendage over time and might be used as surrogate parameter for LAAC success. Increased and stable exercise tolerance after 45 days can be observed.

Abstract
BACKGROUND AND AIMS Direct-acting antivirals (DAAs) against hepatitis C virus (HCV) exert high anti-HCV activity and are expected to show anti-inflammatory effects associated with HCV elimination. Furthermore, hepatocellular carcinoma (HCC) is known to dedifferentiate from hypovascular tumors, such as dysplastic nodules or well-differentiated HCC, to hypervascular tumors. We therefore explored whether or not DAAs can suppress the growth and hypervascularization of hypovascular tumors. METHODS We enrolled 481 patients with HCV genotype 1 infection who were treated with Daclatasvir and Asunaprevir therapy. Of these, 29 patients had 33 hypovascular tumors, which were confirmed by contrast-enhanced MRI or CT before therapy. We prospectively analyzed the cumulative incidence of HCC, i.e. the growth or hypervascularization of hypovascular tumors, and compared the HCC development rates between patients with hypovascular tumors and those without any tumors. RESULTS The mean size of the hypovascular tumors was 11.3 mm. Twenty seven of 29 patients who achieved an SVR had 31 nodules, 19 of 31 nodules (61.3%) showed tumor growth or hypervascularization, and 12 (38.7%) nodules showed no change or improvement. The cumulative incidence rates of tumor growth or hypervascularization were 19.4% at 1 year, 36.0% at 2 years, 56.6% at 3 years, and 65.3% at 4 years. Among the patients who achieved a sustained virologic response, the cumulative HCC development rates of patients with hypovascular tumors was significantly higher than in those without any tumors. A Cox proportional hazard analysis showed that a history of HCC therapy, the presence of a hypovascular tumor, and AFP >4.6 ng/mL at the end of treatment were independent risk factors for HCC development. CONCLUSION Hypovascular tumors developed into HCC at a high rate despite the elimination of HCV by DAAs. As patients with hypovascular tumors were shown to have a high risk of HCC development, they should undergo strict HCC surveillance.

Abstract
AIM Direct-acting antiviral (DAA) therapy for hepatitis C virus is associated with high sustained virologic response rates. However, patients for whom DAA therapy fails acquire resistance-associated substitutions (RASs). We therefore evaluated the efficacy of DAA retreatment and factors associated with retreatment failure. METHODS Non-structural 5A RASs were investigated at the start of DAA therapy and at treatment failure in 64 patients with hepatitis C virus genotype 1b for whom DAA combination therapy had failed. A total of 59 patients were introduced to DAA retreatment. The factors associated with retreatment failure were investigated. RESULTS A total of 20 of 43 (46.5%) daclatasvir + asunaprevir-treated patients with virologic failure had no RASs at baseline, and three (15%) acquired P32 deletion RASs. Four of seven sofosbuvir/ledipasvir-treated patients with virologic failure had more than two RASs of NS5A at baseline. The sustained virologic response rates on retreatment were as follows: sofosbuvir/ledipasvir, 81.8%; with elbasvir + grazoprevir, 0%; and glecaprevir/pibrentasvir, 87.5%. Patients for whom sofosbuvir/ledipasvir or elbasvir + grazoprevir failed achieved sustained virologic response with glecaprevir/pibrentasvir. Two of three patients for whom glecaprevir/pibrentasvir retreatment failed had Q24/L28/R30 and A92K RASs; the other had P32 deletion RAS at baseline. Interestingly, 10 of 11 patients with retreatment failure had the interleukin (IL)-28B single-nucleotide polymorphism (SNP) minor allele. A multivariate analysis showed that the IL28B SNP minor allele (P = 0.005, odds ratio 28.291) was an independent risk factor for retreatment failure. CONCLUSIONS In addition to viral factors (e.g. Q24, L28, R30, and A92 or P32 deletion RASs), host factors (e.g. IL28B SNP) are associated with DAA retreatment failure.

Abstract
Abstract
Background
Percutaneous left atrial appendage closure (LAAC) is being established as an alternative option for atrial fibrillation (AF) patients with high bleeding risk. Few studies reported the influence of percutaneous LAAC on left atrial (LA) performance, but most of the studies demonstrated no remarkable changes in their parameters after the procedure.
Method
The study included 95 patients (age: 75±6.7 years, 67% male) whom underwent percutaneous LAAC in a single center between September 2012 and November 2018. LA strain was evaluated at three different time intervals by transesophageal echocardiography (baseline, 45 days and 180 days after procedure). All data were analyzed using a dedicated. 70 patients had atrial fibrillation whereas 25 were in sinus rhythm. Analysis was performed for peak atrial longitudinal strain (PALS) and peak atrial contraction strain (PACS) from segment of lateral wall in mid-esophageal 4 chamber view. The validity of lateral wall left atrial analysis was recently shown by our group. PACS was obtained in patients with sinus rhythm during exams.
Results
Compared to baseline, PALS was significantly increased after 45 days (12.4±8.4% vs 16.0±10.7%, p=0.001) and remained stable after 180 days (13.8±9.0% vs 17.0±12.4%, p=0.098). Even in only patients with atrial fibrillation during exams, it was increased (10.8±7.7% vs 13.4±7.1%, p=0.012 and 8.5±5.1% vs 13.9±8.1%, p=0.014). Similarly, compared with the baseline, PACS was significantly increased after 45 days and 180 days (5.8±3.9% vs 10.6±7.6%, p=0.001 and 4.5±2.6% vs 7.9±3.1%, p=0.036).
The Changes in PALS and PACS
Conclusion
Our study has demonstrated for the first time the improvement in LA strain following LAAC within 45 days of implantation by transesophageal echocardiography and these values were maintained at least for 6 months. Further appraisal is warranted for confirmation of these preliminary findings.

Abstract
A 68-year-old Japanese man with decompensated cirrhosis due to hepatitis C virus (HCV) genotype 1b infection was treated with sofosbuvir (SOF; 400 mg/day), ledipasvir (LDV; 90 mg/day), and ribavirin (RBV; 400 mg/day). Before treatment, his Child-Pugh and Model for End-Stage Liver Disease (MELD) scores were 10 (class C) and 13 points, respectively. Although RBV was initially given at two-thirds the normal dose due to anemia, his hemoglobin level gradually declined, and RBV was reduced to 200 mg daily on day 11, and 200 mg every other day on day 14. His alanine aminotransferase level gradually decreased during combination therapy; and HCV-RNA was undetectable on day 28. He complained of fatigue from day 49, and RBV was ceased. On day 56, he asked to discontinue treatment because of strong fatigue and insomnia. As hepatic encephalopathy occurred just after the cessation of direct-acting antivirals, diuretics were discontinued, and treatment with synthetic disaccharides and intractable antibiotics were given, after which his consciousness returned to normal. Ascites gradually disappeared, and a sustained virologic response (SVR) was achieved. At 1.5 years after treatment, his Child-Pugh and MELD scores had improved to 6 (class A) and 10 points, respectively. Although he did not experience hepatic encephalopathy during the observation period, his blood ammonia concentration persistently increased. We reported a case of decompensated cirrhosis in a patient who achieved SVR with SOF/LDV plus RBV for 8 weeks. Although his liver function improved after treatment, careful long-term observation is required for complications of liver cirrhosis, even after HCV elimination.

Abstract
OBJECTIVE The present study aimed to reveal the factors associated with virologic failure in sofosbuvir and ledipasvir (SOF/LDV)-treated patients, and identify baseline NS5A or NS5B resistance-associated substitutions (RASs). METHODS Four hundred ninety-three patients with Hepatitis C Virus (HCV) genotype 1b infection were treated with SOF/LDV; 31 had a history of interferon (IFN)-free treatment with daclatasvir and asunaprevir. The effect of baseline RASs on the response to SOF/LDV therapy was analyzed. RESULTS Overall, a sustained virologic response at 12 weeks (SVR12) was achieved in 476 patients (96.6%). The SVR12 rates in the patients with IFN-free treatment-naïve and retreatment were 97.6% and 80.6%, respectively. HCV elimination was not achieved in 17 patients, 11 (including 5 with IFN-free retreatment) of whom had virologic failure. Eight patients had coexisting NS5A RASs of Q24, L28 and/or R30, L31, or Y93 and one patient had coexisting NS5A RASs of P32L and A92K. Interestingly, 10 and 8 patients had NS5B A218S and C316N RAS respectively. According to a multivariate analysis, coexisting NS5A RASs, NS5A P32 RAS, NS5B A218 and/or C316 RASs, and γ-glutamyltranspeptidase were associated with virologic failure. In the naïve patients, all patients without NS5B A218 and/or C316 RAS achieved an SVR12. Notably, the SVR12 rates of patients with coexisting NS5A and NS5B RASs were significantly lower (83.3%). CONCLUSIONS Although SOF/LDV therapy resulted in a high SVR12 rate, coexisting NS5A and NS5B RASs were associated with virologic failure. These results might indicate that the coexisting baseline RASs influence the therapeutic effects of SOF/LDV.

Abstract
BACKGROUND Daclatasvir (DCV) and asunaprevir (ASV) combination therapy has been primarily used in patients without NS5A L31 or Y93 resistance-associated substitutions (RASs) before treatment. We examined the characteristics of patients without these baseline RASs who did not achieve hepatitis C virus eradication with DCV and ASV combination therapy and identified new baseline NS5A RASs that are closely associated with failure of combination therapy. METHODS Three hundred thirty-five patients with hepatitis C virus genotype 1 infection with no NS5A L31, NS5A Y93, and NS3 D168 RASs before DCV and ASV combination therapy and no history of protease inhibitor therapy were enrolled. All RASs were evaluated by direct sequencing. RESULTS Sustained virologic response at 12 weeks (SVR12) was achieved in 297 patients (89%). Patients with NS5A Q24, L28, and/or R30 RASs or concomitant NS5A F37 and Q54 RASs had a significantly lower SVR12 rate than patients without these RASs (70% vs 92%, p < 0.001 and 79% vs 92%, p = 0.002 respectively). Multivariate analysis showed that NS5A Q24, L28, and/or R30 RASs and concomitant NS5A F37 and Q54 RASs were significantly associated with virologic failure. The SVR12 rate in patients without NS5A Q24, L28, and/or R30 RASs and concomitant NS5A F37 and Q54 RASs was 96.2% (202/210). CONCLUSIONS In patients without NS5A L31 or Y93 RASs, the presence of NS5A Q24, L28, and/or R30 RASs and concomitant NS5A F37 and Q54 RASs at the baseline was associated with failure of DCV and ASV combination therapy. The coexistence of baseline RASs other than NS5A L31 and Y93 may affect the therapeutic effectiveness of DCV and ASV combination therapy.

Abstract
AIM Tolvaptan, an oral active vasopressin V2 receptor antagonist, is widely used for hepatic edema in Japan, but its clinical benefits have yet to be fully clarified. The present study evaluated the efficacy of tolvaptan in hepatic edema. METHODS The efficacy and treatment regimen of tolvaptan were evaluated in 150 patients with hepatic edema by analyzing the initial (day 14) and long-term (day 90) responses to the drug and their predictive factors. All patients were divided into good (Child-Pugh classification B, and absent of advanced hepatocellular carcinoma) and poor hepatic condition groups, and the response rates were compared between the two groups. RESULTS The initial response rate was 62%, and the long-term response rate was 47%. The assessment of predictive factors for response to tolvaptan showed that serum creatinine and C-reactive protein levels were important predictors of initial response, and that hepatic conditions, such as the Child-Pugh score or presence of hepatocellular carcinoma, as well as initial response, were significant predictors of long-term response. In addition, both the initial and long-term response rates and the cumulative survival rate were found to be higher in the good hepatic condition group than in the poor hepatic condition group, respectively (71% vs. 57%, P = 0.113; 62% vs. 39%, P = 0.009; log-rank test, P < 0.001). CONCLUSION These results suggest that tolvaptan may provide high response rates when used early in the course of hepatic edema, or when both hepatic and renal functions are still retained, leading to an improved disease prognosis.

Abstract
The TATA box-binding factor TFIID mediates transcriptional regulation through interactions with various regulatory factors and putative participation in reconfiguration of nucleosomes, utilizing its components, which include TATA box-binding protein (TBP) and TBP-associated factors (TAFs). Our and other previous studies have elucidated that there exist histone-similar TAFs. Studies on TAFs similar to histone H3 and H4 have revealed their biochemical and structural similarities to the corresponding histones. However, the existence of histone-like interactions involving the other TAFs is still ambiguous. Here we report the analyses with a two-hybrid system of the mutually interacting regions between hTAF(II)80 and hTAF(II)22, which resemble histone H4 and H2B, respectively. The results demonstrate the indispensability of the histone fold motifs of these two TAFs for mutual interaction. Together with earlier biochemical or structural studies, the present results suggest the presence of a histone octamer-like partial TAF complex and its involvement in transcription from chromatin templates.

Abstract
Escherichia coli D2 (serotype 07:H-) that was isolated from a child with diarrhea hybridized with an F1845 DNA probe used to detect diffuse adherence. Strain D2 adhered to tissue culture cells (HeLa and HEp-2 cells) in a clustered pattern but did not autoagglutinate on the cell surface and induced the elongation of microvilli after 3 h of incubation. After 6 h of incubation, the infected cells were positive for fluorescent-actin staining at the site of clustered adherence. When analyzed with a confocal laser scanning microscope, each D2 cell was surrounded by accumulated actin in a capsule-like formation. Capsule-like, accumulated actin was also observed with enteropathogenic E. coli (EPEC), although in this case, actin accumulation was associated with EPEC microcolonies in a localized pattern. Four other strains of F1845 DNA probe-positive, diffusely adhering E. coli were negative for actin accumulation. Strain D2 did not hybridize with EPEC attaching and effacing DNA or EPEC adherence factor DNA probes. In addition, clustered D2 cells were found inside tissue culture cells. The data suggest a novel infectious mechanism as well as genetic heterogeneity of F1845 DNA probe-positive E. coli. Capsule-like, accumulated actin may protect the bacteria from host defense mechanisms.
