ABSTRACT
BACKGROUND: This study aimed to clarify the morphological changes in esophageal varices after achieving sustained virological response (SVR) with direct-acting antivirals (DAAs) in patients with cirrhosis. METHODS: A total of 243 patients underwent esophagogastroduodenoscopy before DAA treatment and after achieving SVR. Morphological changes in esophageal varices were investigated using esophagogastroduodenoscopy. RESULTS: This study comprised 125 males and 118 females with a median age of 68 years. Esophageal varices at baseline were classified into no varix in 155 (63.8%), F1 in 59 (24.3%), F2 in 25 (10.3%) and F3 in 4 (1.6%) patients. The improvement, unchanged, and aggravation rates of esophageal varices after SVR were 11.9%, 73.3%, and 14.8%, respectively. High ALBI score at SVR12 was an independent factor associated with post-SVR esophageal varices aggravation (p = 0.045). Time-dependent receiver operating characteristic (ROC) curve analysis revealed a cut-off value of - 2.33 for ALBI score at SVR12 in predicting post-SVR esophageal varices aggravation. Of the 155 patients without esophageal varices at baseline, 17 developed de novo post-SVR esophageal varices. High ALBI score at SVR12 was a significant independent factor associated with de novo post-SVR esophageal varices (p = 0.046). ROC curve analysis revealed a cut-off value of - 2.65 for ALBI score at SVR12 in predicting de novo post-SVR esophageal varices. CONCLUSIONS: Patients with cirrhosis can experience esophageal varices aggravation or de novo esophageal varices, despite achieving SVR. In particular, patients with high ALBI score at SVR12 have a high likelihood of developing post-SVR esophageal varices aggravation or de novo post-SVR esophageal varices.

AIM: An association between hepatitis B core-related antigen (HBcrAg) kinetics and hepatocarcinogenesis during nucleoside (t)id analog (NA) treatment has recently been reported. HBcrAg kinetics and factors associated with HBcrAg response during tenofovir alafenamide (TAF) administration remain unclear. In this multicenter retrospective study, we aimed to clarify the efficacy and safety of TAF in treatment-naïve patients with chronic hepatitis B, focusing on the reduction in HBcrAg levels. METHODS: Patients were treated with TAF monotherapy for 96 weeks, and the kinetics of HBcrAg during treatment and the factors associated with HBcrAg response (defined as a change in HBcrAg of -1 log IU/mL from baseline) were evaluated. RESULTS: The study population comprised 241 patients, 36.9% of whom were HBeAg-positive. The median baseline HBcrAg level was 4.7 log IU/mL. The median change in HBcrAg from baseline was -1.1 log IU/mL at 96 weeks after treatment. The HBcrAg response rate at 96 weeks was 56.6% (43/76). Multivariate analysis revealed high alanine transaminase level as an independent baseline factor associated with HBcrAg response at 96 weeks of treatment (p = 4.53 × 10-6). No correlation was found between the HBcrAg and hepatitis B surface antigen kinetics in patients treated with TAF monotherapy. CONCLUSIONS: In TAF monotherapy for patients with chronic hepatitis B, HBcrAg levels were significantly decreased and baseline alanine transaminase level is an important factor associated with HBcrAg reduction. As no correlation was found between HBcrAg and reduced hepatitis B surface antigen levels in this study, HBcrAg kinetics in addition to hepatitis B surface antigen may need to be monitored during TAF treatment.
ABSTRACT
BACKGROUND AND AIM: The benefits of entecavir (ETV) versus tenofovir disoproxil fumarate (TDF) in reducing the development of chronic hepatitis B (CHB)-related hepatocellular carcinoma remain controversial. Whether mortality rates differ between patients with CHB treated with ETV and those treated with TDF is unclear. METHODS: A total of 2542 patients with CHB treated with either ETV or TDF were recruited from a multinational cohort. A 1:1 propensity score matching was performed to balance the differences in baseline characteristics between the two patient groups. We aimed to compare the all-cause, liver-related, and non-liver-related mortality between patients receiving ETV and those receiving TDF. RESULTS: The annual incidence of all-cause mortality in the entire cohort was 1.0/100 person-years (follow-up, 15 757.5 person-years). Patients who received TDF were younger and had a higher body mass index, platelet count, hepatitis B virus deoxyribonucleic acid levels, and proportion of hepatitis B e-antigen seropositivity than those who received ETV. The factors associated with all-cause mortality were fibrosis-4 index > 6.5 (hazard ratio [HR]/confidence interval [CI]: 3.13/2.15-4.54, P < 0.001), age per year increase (HR/CI: 1.05/1.04-1.07, P < 0.001), alanine aminotransferase level per U/L increase (HR/CI: 0.997/0.996-0.999, P = 0.003), and γ-glutamyl transferase level per U/L increase (HR/CI: 1.002/1.001-1.003, P < 0.001). No significant difference in all-cause mortality was observed between the ETV and TDF groups (log-rank test, P = 0.69). After propensity score matching, no significant differences in all-cause, liver-related, or non-liver-related mortality were observed between the two groups. CONCLUSIONS: Long-term outcomes of all-cause mortality and liver-related and non-liver-related mortality did not differ between patients treated with ETV and those receiving TDF.

Elevated serum gamma-glutamyl transferase (GGT) levels are associated with chronic hepatitis B (CHB)-related hepatocellular carcinoma. However, their role in predicting mortality in patients with CHB treated with nucleotide/nucleoside analogs (NAs) remains elusive. Altogether, 2843 patients with CHB treated with NAs were recruited from a multinational cohort. Serum GGT levels before and 6 months (Month-6) after initiating NAs were measured to explore their association with all-cause, liver-related, and non-liver-related mortality. The annual incidence of all-cause mortality was 0.9/100 person-years over a follow-up period of 17,436.3 person-years. Compared with patients who survived, those who died had a significantly higher pretreatment (89.3 vs. 67.4 U/L, p = 0.002) and Month-6-GGT levels (62.1 vs. 38.4 U/L, p < 0.001). The factors associated with all-cause mortality included cirrhosis (hazard ratio [HR]/95% confidence interval [CI]: 2.66/1.92-3.70, p < 0.001), pretreatment GGT levels (HR/CI: 1.004/1.003-1.006, p < 0.001), alanine aminotransferase level (HR/CI: 0.996/0.994-0.998, p = 0.001), and age (HR/CI: 1.06/1.04-1.07, p < 0.001). Regarding liver-related mortality, the independent factors included cirrhosis (HR/CI: 4.36/2.79-6.89, p < 0.001), pretreatment GGT levels (HR/CI: 1.006/1.004-1.008, p < 0.001), alanine aminotransferase level (HR/CI: 0.993/0.990-0.997, p = 0.001), age (HR/CI: 1.03/1.01-1.05, p < 0.001), and fatty liver disease (HR/CI: 0.30/0.15-0.59, p = 0.001). Pretreatment GGT levels were also independently predictive of non-liver-related mortality (HR/CI: 1.003/1.000-1.005, p = 0.03). The results remained consistent after excluding the patients with a history of alcohol use. A dose-dependent manner of <25, 25-75, and >75 percentile of pretreatment GGT levels was observed with respect to the all-cause mortality (trend p < 0.001). Pretreatment serum GGT levels predicted all-cause, liver-related, and non-liver-related mortality in patients with CHB treated with NAs.

AIM: Cabozantinib (CAB), a multiple kinase inhibitor, has been approved for use in patients with previously treated unresectable hepatocellular carcinoma (uHCC). However, real-world clinical data are lacking, particularly clinical data regarding dose modifications of CAB. We analyzed the clinical outcomes of CAB in uHCC and compared treatment outcomes between the full- and reduced-dose groups. METHODS: This multicenter, observational study included patients with uHCC who were treated with CAB from March 2021 to April 2022. Patient characteristics, efficacy, and safety were compared between the full- and reduced-dose groups. RESULTS: Twenty-six patients from eight institutes were analyzed. Cabozantinib was administered as a third-line or later treatment in 25 (96.2%) patients and postimmunotherapy in 21 (80.5%) patients. There were 15 patients in the full-dose group (60 mg CAB) and 11 in the reduced-dose group (40 or 20 mg CAB). The objective response rate (ORR) and disease control rate (DCR) were not significantly different between the two groups. The ORR was 6.7% for the full-dose group and 9.1% for the reduced-dose group, and the DCR was 53.4% and 81.8%, respectively. Progression-free survival analysis showed no significant differences between the two groups. The incidence of decreased appetite, fatigue, and diarrhea, and the rate of discontinuation and dose reduction, was significantly higher in the full-dose group. CONCLUSIONS: Our study suggests that the efficacy and safety of CAB in real-world clinical practice are comparable to those of the phase III trial (CELESTIAL), and that dose reduction of CAB may be a safer treatment option.
ABSTRACT
Hepatocellular carcinoma (HCC) can de novo develop in patients with chronic hepatitis C even after the achievement of sustained virologic response (SVR). We characterized de novo HCC after SVR, comparing it with HCC that developed in patients during persistent hepatitis C virus (HCV) infection. Characteristics, survival rates, and recurrence rates after curative treatment in 178 patients who developed initial HCC after SVR diagnosed between 2014 and 2020 were compared with those of 127 patients with initial HCC that developed during persistent HCV infection diagnosed between 2011 and 2015; HCC was detected under surveillance in both groups. HCC was less advanced and liver function worsened less in patients with SVR than in patients with persistent HCV. The survival rate after diagnosis was significantly higher for patients with SVR than for patients with persistent HCV (1-, 3-, and 5-year survival rates, 98.2%, 92.5%, and 86.8% versus 89.5%, 74.7%, and 60.8%, respectively; P < 0.001). By contrast, the recurrence rate after curative treatment was similar between groups (1-, 3-, and 5-year recurrence rates, 11.6%, 54.6%, and 60.4% versus 24.0%, 46.7%, and 50.4%, respectively; P = 0.7484). Liver function improved between initial HCC diagnosis and recurrence in patients with SVR (P = 0.0191), whereas it worsened in the control group (P < 0.001). In addition, patients with SVR could receive curative treatment for recurrence more frequently than patients with persistent HCV (80.4% versus 47.8%, respectively; P = 0.0008). Conclusion: Survival of patients with de novo HCC after SVR was significantly higher than that of patients in whom HCC developed during persistent HCV infection, despite similar rates of recurrence after curative treatment. A higher prevalence of curative treatment for recurrent HCC and improved liver function contributed to this result.
ABSTRACT
There are limited studies that have evaluated the long-term outcomes in patients with hepatocellular carcinoma (HCC) recurrence after direct-acting antiviral (DAA) treatment. In this retrospective study, we aimed to investigate the recurrence rates, recurrence factors, and prognosis of 130 patients who were treated with IFN-free DAA treatment after treatment for HCC. The median observation time was 41 ± 13.9 months after DAA treatment. The recurrence rates of HCC were 23.2%, 32.5%, 46.3%, and 59.4% at 6, 12, 24, and 36 months, respectively. A multivariate analysis showed that palliative treatment prior to DAA treatment (HR = 3.974, 95% CI 1.924-8.207, p = 0.0006) and alpha-fetoprotein at sustained virological response 12 (HR = 1.048, 95% CI 1.016-1.077, p = 0.0046) were associated with independent factors for HCC recurrence (HCC-R). The 12-, 24-, and 36-month overall survival rates were 97.6%, 94.0%, and 89.8%, respectively. The 12-, 24-, and 36-month survival rates of the non-recurrence and recurrence groups were 97.7%, 97.7%, and 94.1% and 97.6%, 92.3%, and 87.9%, respectively (p = 0.3404). The size of the main tumor lesion and the serological data were significantly improved at the time of HCC-R after DAA treatment. This study showed an improved prognosis regardless of recurrence rate, which suggests that DAA treatment in HCV patients should be considered.
ABSTRACT
Objective Pegylated-interferon monotherapy is the standard treatment for patients with chronic hepatitis B; however, the factors associated with its therapeutic effects remain unclear. Methods Patients with chronic hepatitis B were treated with pegylated interferon α-2a for 48 weeks. We evaluated the kinetics of hepatitis B surface antigen (HBsAg) during treatment and follow-up periods and the factors associated with an HBsAg response (defined as a change in HBsAg of ≥-1 log IU/mL from baseline). Results The study population comprised 50 patients. The median baseline levels of hepatitis B virus DNA and HBsAg were 5.00 and 3.40 log IU/mL. The median values of HBsAg reduction from baseline were -0.44 (n=48), -0.41 (n=40), and -0.68 (n=11) log IU/mL at the end of treatment and at 48 and 144 weeks post-treatment, respectively. The rates of HBsAg response were 24.0% and 22.5% at the end of treatment and at 48 weeks post-treatment, respectively. A multivariate analysis identified HBsAg <3.00 log IU/mL as an independent baseline factor contributing to the HBsAg response at the end of treatment and 48 weeks post-treatment (p=1.07×10-2 and 4.42×10-2, respectively). There were significant differences in the reduction of the HBsAg levels at 12 weeks of treatment and in the incidence of serum ALT increase during treatment between patients with and without an HBsAg response. Conclusion These findings suggest that the baseline HBsAg level, HBsAg kinetics at 12 weeks of treatment, and ALT increase during treatment are important factors contributing to the HBsAg response in pegylated interferon α-2a monotherapy for patients with chronic hepatitis B.

BACKGROUND AND AIM: Although tenofovir alafenamide (TAF), as well as entecavir (ETV), is widely used as first-line treatment for patients with chronic hepatitis B, there are only a few studies comparing sequential therapy from ETV to TAF and continuous ETV monotherapy in patients with maintained virologic response to ETV. METHODS: In a retrospective multicenter study, we investigated the efficacy and safety of sequential therapy from ETV to TAF (ETV-TAF group) and compared them with continuous ETV monotherapy (ETV group), using propensity score matching, in chronic hepatitis B patients. RESULTS: From 442 patients, we analyzed 142 patients from each group comprising 71 patients matched for several data, including age, HBV genotype, hepatitis B envelope antigen, cirrhosis, alanine aminotransferase, platelet count, prior ETV monotherapy period, and hepatitis B surface antigen (HBsAg) change during prior ETV monotherapy. In the ETV-TAF group, HBsAg levels significantly decreased from baseline to 48 weeks after switching to TAF (-0.02 log IU/mL, P = 0.038). HBcrAg levels also significantly decreased after switching to TAF (-0.1 log IU/mL, P = 0.004). However, there were no significant differences in the reduction of HBsAg and HBcrAg levels between the ETV-TAF and ETV groups. There was no significant difference in the change of estimated glomerular filtration rate levels from baseline to 48 weeks between the two groups. CONCLUSIONS: The present study indicated that the efficacy, especially of the HBsAg-reducing action, and safety of sequential therapy from ETV to TAF were similar to those of continuous ETV monotherapy among chronic hepatitis B patients with maintained virologic response to ETV.
ABSTRACT
AIM: Presently, no standardized definition or acceptable diagnostic criteria have been established for acute presentation of autoimmune hepatitis (AP-AIH), making it difficult to differentiate that condition from drug-induced liver injury (DILI). This study aimed to characterize clinical and histological features for distinguishing between AP-AIH and DILI. METHODS: Clinical, biochemical, and histological characteristics of AP-AIH and DILI in clinically well-characterized cases were compared in a standardized manner to clarify differences. RESULTS: In clinical evaluations, immunoglobulin G level and rate of anti-nuclear antibody positivity were greater in AP-AIH than DILI cases. As for diagnosis of each condition, significant (P < 0.01) differences were found for 10 features: lobular necrosis/inflammation, cobblestone appearance of hepatocytes, plasma cell infiltration in liver parenchyma, centrilobular fibrosis, hepatic rosette formation in areas with cobblestone appearance, portal inflammation, interface hepatitis, prominent plasma cells in portal areas, bile duct injury, and hepatic rosette formation in periportal areas. The area under the curve and cut-off values for the combination of these 10 features were 0.95 and 9 (sensitivity 86%, specificity 90%), respectively. CONCLUSION: Combinations of histological features were found to be helpful for differentiating AP-AIH from DILI, but we were not able to statistically identify an individual feature as definitive.
ABSTRACT
Direct acting antivirals (DAA) have recently been developed to treat patients with hepatitis C virus (HCV) infection, and interferon-free DAA treatment has improved the cure rate of patients. However, the occurrence rate of hepatocellular carcinoma (HCC) following HCV eradication remains unknown. Therefore, the present study aimed to identify predictors of HCC occurrence following DAA treatment. Among 1,454 patients infected with HCV, 1,088 patients who achieved sustained virologic response and who had no history of HCC treatment were recruited between September 2014 and November 2018. The incidence of HCC in patients infected with HCV following DAA treatment, and the predictors contributing to HCC occurrence were identified using clinicopathological characteristics and blood test results. During the present study, 26 patients developed HCC. The incidence of HCC was 0.61, 1.88, 2.82 and 3.71% at 6, 12, 18 and 24 months after treatment with DAA, respectively. The results of multivariate analysis identified age [hazard ratio (HR), 1.0729; P=0.0044] and α-fetoprotein (AFP) level after DAA treatment (HR, 1.0486; P=0.0486) as independent factors that may contribute to HCC occurrence following DAA treatment. By using these two factors, a novel scoring system (0-2 points) was established to predict HCC occurrence following HCV eradication by DAA treatment. The incidence of HCC at 2 years was 0.3% in the 0 points group, 6.27% in the 1 point group and 18.37% in the 2 points group. In conclusion, AFP level after DAA treatment and age at DAA administration were identified as independent predictors of HCC occurrence in patients that were treated with DAA. The scoring system that was established in the present study is simple and easy, and using pre-treatment factors may be a convenient tool to predict the risk of HCC occurrence in HCV-free patients following DAA treatment.
ABSTRACT
BACKGROUND AND AIM: The prognosis of cirrhotic patients with hepatic edema is poor. Although several short-term predictors of tolvaptan (novel diuretic agent) treatment for such patients have been reported, the factors related to long-term survival are still unclear. METHODS: Among 459 patients with hepatic edema enrolled in a retrospective, multicenter collaborative study, we analyzed 407 patients who received tolvaptan. RESULTS: Patients consisted of 266 men and 141 women, with the median age of 68 years (range, 28-93 years). The frequency of short-term responders to tolvaptan was 59.7% (243/407). In the Cox regression analysis, short-term response to tolvaptan, low average dosages of furosemide and spironolactone during tolvaptan treatment, Child-Pugh classification A and B, and absence of hepatocellular carcinoma were independent factors contributed to 1-year survival. The 1-year and long-term cumulative survival rates in short-term responders were significantly higher than those in non-responders (P = 0.011 and 0.010, respectively). Using a receiver operating characteristic curve analysis, the optimal cut-off values of average daily dosages of furosemide and spironolactone for predicting 1-year survival were 19 and 23 mg/day, respectively. The long-term cumulative survival rates in patients who received a mean dosage of spironolactone < 23 mg/day during tolvaptan treatment were significantly higher than those receiving a mean dosage of ≥ 23 mg/day (P = 0.001). CONCLUSIONS: The present study suggests that the short-term response to tolvaptan and low dosages of conventional diuretics during tolvaptan treatment might improve the 1-year and long-term survival rates in cirrhotic patients with hepatic edema.

BACKGROUND: We investigated changes in patient characteristics, rate of sustained virologic response (SVR), and factors associated with SVR after anti-hepatitis C virus (HCV) therapy with direct-acting antiviral (DAA) regimens in real-world practice in Japan, where patients with HCV are characterized by older age and high prevalence of cirrhosis and hepatocellular carcinoma (HCC). METHODS: Changes in patient characteristics and SVR rates were evaluated from medical records among 10 688 patients who started interferon (IFN)-free DAA therapy between September 2014 and June 2018 in a nationwide, multicenter study. Factors associated with failure of SVR were analyzed. In particular, effects of cirrhosis or history of HCC on SVR were assessed by exact matching. RESULTS: Patient age was becoming younger and baseline liver fibrosis was becoming milder over time. Overall SVR rate was 95.4%. The SVR rates increased over time in patients without a history of IFN-free DAA therapy. Multivariate analysis revealed that cirrhosis was unfavorably associated with achievement of SVR in both patients with genotype 1 (odds ratio, 1.68; 95% confidence interval [CI], 1.27-2.21) and genotype 2 (odds ratio, 1.69; 95% CI, 1.01-2.78). Comparisons after exact matching showed that the SVR rate was significantly lower in patients with cirrhosis than without it, whereas patients with and without a history of HCC had similar SVR rates. CONCLUSIONS: Background characteristics of patients who undergo IFN-free DAA therapy are changing in Japan. Patients without a history of IFN-free DAA therapy have high SVR rates. Exact matching confirmed that cirrhosis significantly influences the achievement of SVR in real-world settings.
ABSTRACT
BACKGROUND: The virological efficacy and safety of the direct-acting antiviral (DAA) regimen consisting of daclatasvir, asunaprevir, and beclabuvir (DCV/ASV/BCV) for patients chronically infected with hepatitis C virus (HCV) genotype 1 have not been previously evaluated in Japanese real-world settings. METHODS: In a Japanese nationwide multicenter study, the rate of sustained virologic response (SVR) and safety were analyzed in 91 patients who started the DCV/ASV/BCV regimen between November 2016 and July 2017. SVR rates were compared based on baseline patient characteristics. RESULTS: More than 60% of patients had a history of failure to achieve SVR with interferon (IFN)-free DAA therapy. Overall, 50 of 91 patients (54.9%) achieved SVR. Multivariate analysis identified a history of failure with IFN-free DAA therapy and pretreatment HCV RNA levels as factors significantly associated with treatment failure. Whereas the SVR rate in patients without a history of IFN-free DAA therapy was 91.7% (33 of 36 patients), it was only 30.9% (17 of 55 patients) among patients with a history of IFN-free DAA therapy. The rate of discontinuation due to an adverse event was 4.4%. CONCLUSIONS: Many patients treated with the DCV/ASV/BCV regimen have a history of a failure to achieve SVR with previous IFN-free DAA therapy. SVR rate was not as high as that in pre-approval clinical trial of this regimen in IFN-free DAA-naïve patients. In addition, most patients with a history of failure with IFN-free DAA therapy, particularly the DCV/ASV regimen, showed resistance to this regimen.

BACKGROUND: The aim of this study is to ascertain whether the TLL1 variant at rs17047200 is associated with the development of HCC after achieving sustained virological response (SVR) by interferon (IFN)-free therapy for chronic hepatitis C (CHC). METHODS: A total of 1029 Japanese CHC patients with the following inclusion criteria were enrolled: (i) achieved SVR by IFN-free therapy, (ii) followed up at least 1 year from the end of treatment (EOT) (median 104 weeks), (iii) no history of hepatocellular carcinoma (HCC) by 1 year from the EOT. RESULTS: Nineteen patients developed HCC (HCC group) and 1010 did not (non-HCC group). The proportion of rs17047200 AT/TT was significantly higher in the HCC group than the non-HCC group (47.4% vs. 20.1%, P = 0.008). Multivariate analysis showed that higher levels of α-fetoprotein, FIB-4 and rs17047200 AT/TT were independent risk factors for developing HCC (HR = 3.22, P = 0.021 for α-fetoprotein > 4.6 ng/ml; HR = 3.89, P = 0.036 for FIB-4 > 2.67; HR = 2.80, P = 0.026 for rs17047200 AT/TT). Cumulative incidence of HCC was significantly higher in patients with rs17047200 AT/TT than in those with AA (P = 0.006). Comparing clinical characteristics according to the TLL1 genotypes, patients with rs17047200 AT/TT had significantly lower platelet counts and higher levels of FIB-4 than those with AA (P = 0.011 and 0.032, respectively). CONCLUSIONS: The TLL1 variant was independently associated with HCC development after HCV eradication by IFN-free regimen. It might be involved in hepatic fibrogenesis and thereby carcinogenesis.

BACKGROUND: The real-world virological efficacy and safety of an interferon (IFN)-free direct-acting antiviral (DAA) therapy with elbasvir (EBR) and grazoprevir (GZR) were evaluated in Japanese patients chronically infected with hepatitis C virus (HCV) genotype 1. METHODS: The rate of sustained virologic response (SVR) and safety were analyzed in patients who started the EBR/GZR regimen between November 2016 and July 2017. SVR rates were compared based on patient baseline characteristics. RESULTS: Overall, 371 of 381 patients (97.4%) achieved SVR. Multivariate analysis identified a history of failure to IFN-free DAA therapy and the presence of double resistance-associated substitutions (RASs) in HCV non-structural protein 5A (NS5A) as factors significantly associated with failure to EBR/GZR treatment. The SVR rates of patients with a history of IFN-free DAA therapy and those with double RASs were 55.6 and 63.6%, respectively. In all other subpopulations, the SVR rates were more than 90%. There were no severe adverse events associated with the treatment. CONCLUSIONS: The EBR/GZR regimen yielded high virological efficacy with acceptable safety. Patients with a history of failure to IFN-free DAA therapy or with double RASs in HCV-NS5A remained difficult to treat with this regimen.

OBJECTIVE: To determine the relationship between treatment outcomes and hand-foot syndrome (HFS), and the relationship between survival rate and post-progression treatment after sorafenib therapy. METHODS: The study assessed 314 patients with advanced hepatocellular carcinoma (HCC) treated with sorafenib at 5 general hospitals in Kagawa Prefecture, Japan. RESULTS: At the start of sorafenib therapy, 23.6% of the patients had HCC of a Child-Pugh class other than A. The initial sorafenib dose was 800 mg in 9.2% of the patients and 400 mg in 64.3%. Time to progression was 129 days (95% CI: 87.3-170.7) and the median overall survival (OS) was 392 days (95% CI: 316.0-468.0). The OS of the patients with Child-Pugh class A HCC was significantly better than that of the patients with Child-Pugh class B HCC (p < 0.0001). The survival curves for Child-Pugh class A-5 points and class A-6 points were significantly different, with that for class A-5 points being better (p < 0.0001). A significant difference was observed between the patients who exhibited HFS and those who did not, with the former exhibiting a better survival rate (p < 0.001). In addition, the survival rate of the patients who received post-progression treatment after sorafenib therapy was significantly better than that of the patients who did not (p < 0.001). CONCLUSION: In sorafenib therapy, patients with HFS and those who received post-progression treatment exhibited good OS.

AIM: Acute-onset autoimmune hepatitis (AIH) histopathologically presents with features of acute hepatitis and lacks a specific diagnostic method. Also, AIH is often difficult to differentiate from drug-induced liver injury (DILI). We aimed to investigate the final clinical diagnosis of these cases, and compare the clinical, biochemical, and histological characteristics of AIH vs. DILI. METHODS: We examined the Digestive Disease Week Japan 2004 (DDW-J) scale scores, AIH scores, clinical data, and pathological findings in 20 patients in whom it was difficult to differentiate autoimmune liver disease from DILI. RESULTS: In cases with a DDW-J scale score of ≥5, there was a good correlation between the final diagnosis and DDW-J scale assessments, but in cases with a DDW-J scale score of â¦4 they did not correlate well. The scores for pathological findings, such as cobblestone hepatocellular change (p = 0.015), interface hepatitis (p = 0.012), and prominent plasma cells in portal areas (p = 0.011), were higher in the AIH group than in the DILI group. CONCLUSION: This study showed that DDW-J scale was useful for differentiating AIH from DILI in cases with a DDW-J scale score of â§5. The histologic features of AIH were characterized by cobblestone hepatocellular change, interface hepatitis, and plasma cell infiltration of the portal region.

AIM: This study explored treatment outcomes of sofosbuvir (SOF)/ledipasvir (LDV) therapy for chronic hepatitis C patients with and without prior daclatasvir (DCV)/asunaprevir (ASV) therapy. METHODS: Overall, 530 Japanese patients who were infected with hepatitis C virus genotype 1 received SOF/LDV therapy for 12 weeks, and resistance-associated variants (RAVs) in the hepatitis C virus non-structural protein (NS)5A and NS5B regions were assessed at baseline and virological relapse by direct sequencing. RESULTS: Sustained virological response (SVR) rates did not significantly differ between patients with and without NS5A Y93H/N (94.2% [113/120] vs. 97.7% [345/353]), but the SVR rate was significantly lower in patients with prior DCV/ASV therapy compared to those without (69.2% [18/26] vs. 98.4% [496/504], P < 0.001). Among 26 patients with prior DCV/ASV therapy, the prevalence of NS5A multi-RAVs (≥2) was similar between responders and non-responders (61% [11/18] vs. 75% [5/8]), but all patients without RAVs achieved SVR. Multivariate analysis showed that prior DCV/ASV therapy and history of hepatocellular carcinoma were independently associated with treatment failure (odds ratio, 37.55; 95% confidence interval, 10.78-130.76; P < 0.001 for prior DCV/ASV therapy; odds ratio, 4.42; 95% confidence interval, 1.09-18.04; P = 0.03 for the history of HCC). All SOF/LDV failure patients (n = 8) with prior DCV/ASV treatment had two or more factors of cirrhosis, IL28B unfavorable genotype, and baseline NS5A multi-RAVs. The multiple NS5A RAVs had increased but NS5B substitutions, C316N/A207T/A218S or L159F, had not changed at the time of relapse. CONCLUSIONS: Prior DCV/ASV therapy is associated with failure of SOF/LDV therapy due to multiple RAVs.
ABSTRACT
BACKGROUND & AIMS: Anti-hepatitis C virus (HCV) therapy by interferon (IFN)-free regimen with oral direct-acting antiviral drugs are tolerable in aged patients, with fewer adverse effects than IFN-based therapies. We investigated the efficacy and tolerability of an IFN-free anti-HCV therapy in extremely aged patients, as well as the survival benefit of sustained virologic response (SVR). METHODS: Following IFN-free therapy with daclatasvir and asunaprevir, tolerability and SVR rate were compared between 115 HCV genotype 1-infected patients aged 80years or older, 151 patients in their 70s (⩾70 and <80years), and 115 patients under the age of 70. One-year mortality and morbidity in patients aged ⩾80years were compared between SVR patients and propensity score-matched patients with persistent HCV infection. RESULTS: The SVR rate was 96.5% in patients ⩾80years, comparable to that in patients aged ⩾70 and <80years (95.4%) and patients aged <70years (93.9%). There were no differences in treatment discontinuation rate (2.6%, 1.3%, and 0.9%, respectively). One-year mortality was significantly lower in SVR patients (2.7%) than in patients with persistent HCV infection (15.3%, p=0.0016). Whereas 1-year mortality due to liver-related diseases was 8.1% in patients with persistent HCV infection who were aged ⩾80years, no SVR patients died from liver diseases within 1-year after the end of therapy. CONCLUSIONS: IFN-free therapy for HCV infection was associated with high tolerability and antiviral efficacy, even in patients aged ⩾80years. In addition, there seemed to be a survival benefit from the eradication of HCV in this population. LAY SUMMARY: IFN-free therapy with oral direct-acting antiviral drugs (daclatasvir and asunaprevir) for HCV infection showed similar tolerability and antiviral efficacy in patients aged ⩾80years as in younger patients (patients aged ⩾70 and <80years and patients aged <70years), with an SVR rate over 90% and no severe adverse effects. There was a survival benefit from the eradication of HCV even in patients aged ⩾80years.
