Long-read deep sequencing analysis of hepatitis B virus quasispecies in two elderly cases of interspousal transmission.

Hepatitis B virus (HBV) can be transmitted within a family, but an interspousal transmission in elderly cases is rare and the change of viral quasispecies during the event is unclear. We experienced two acute hepatitis B males (AH1 and AH2, 67 and 71 years old, respectively) whose HBV was transmitted from their wives with chronic HBV infection (CH1 and CH2, 67 and 66 years old, respectively). To clarify the characteristics of HBV quasispecies in such cases, we performed long-read deep sequencing of HBV preS1/preS2/S domain using samples from the 2 couples.

Change in Liver Function in Durvalumab Plus Tremelimumab Treatment for Unresectable Hepatocellular Carcinoma.

Background/aim: Maintaining liver function throughout the treatment of hepatocellular carcinoma (HCC) is crucial, yet the impact of durvalumab plus tremelimumab (DT) treatment on liver function is not well understood. This multicenter study aimed to examine the changes in liver function during DT treatment.

Patients And Methods: This nationwide multicenter study included 80 patients who received DT treatment for unresectable HCC.

ALBI score predicts morphological changes in esophageal varices following direct-acting antiviral-induced sustained virological response in patients with liver cirrhosis.

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.

Usefulness of the Fibrosis-4 index and alanine aminotransferase at 1 year of nucleos(t)ide analog treatment for prediction of hepatocellular carcinoma in chronic hepatitis B patients.

Aim: Nucleos(t)ide analogs do not completely prevent hepatocellular carcinoma (HCC) in chronic hepatitis B virus infection. This study aimed to evaluate the dynamics of a non-invasive liver fibrosis marker, the Fibrosis-4 (FIB-4) index, for predicting HCC development.

Methods: Among a total of 882 chronically hepatitis B virus infection-infected patients who were treated with nucleos(t)ide analogs, 472 patients without HCC history whose FIB-4 at baseline and 1 year of treatment was obtained were evaluated for the incidence of HCC.

Necessity for surveillance for hepatocellualr carcinoma in older patients with chronic hepatitis C who achieved sustained virological response.

Background And Aim: Hepatocellular carcinoma (HCC) surveillance in low-risk patients (annual incidence <1.5%) is not recommended per the American Association for the Study of Liver Diseases guidelines. Because patients with chronic hepatitis C with non-advanced fibrosis who have achieved sustained virological response (SVR) have a low risk of HCC, HCC surveillance is not recommended for them.

Effects on survival of the adverse event of atezolizumab plus bevacizumab for hepatocellular carcinoma: a multicenter study by the Japan Red Cross Liver Study Group.

This study aimed to describe the real-world efficacy and safety of the combination therapy of atezolizumab and bevacizumab (Atezo/Bev) for unresectable hepatocellular carcinoma (HCC). This retrospective analysis of a multicenter registry cohort included 268 patients treated with Atezo/Bev. The incidence of adverse events (AE) and its impact on overall survival (OS) and progression-free survival (PFS) were analyzed.

Switching to Tenofovir Alafenamide Fumarate in Chronic Hepatitis B Patients Who Had Detectable HBV DNA during Treatment with Entecavir.

Nucleos(t)ide analogues (NAs) suppress hepatitis B virus (HBV) replication, but the risk of hepatocellular carcinoma still remains. The presence of detectable HBV DNA in the serum during NA therapies for chronic hepatitis B patients has been reported to be associated with the risk of hepatocellular carcinoma. In this study, we investigated the antiviral effect of switching from entecavir (ETV) to tenofovir alafenamide fumarate (TAF) in chronic hepatitis B patients who had detectable HBV DNA in the serum at least once within a year.

Optimal threshold of alpha-fetoprotein response in patients with unresectable hepatocellular carcinoma treated with atezolizumab and bevacizumab.

Alpha-fetoprotein (AFP) response (relative decline in AFP) is associated with imaging response evaluated by response evaluation criteria in solid tumors ver1.1 (RECIST) and survival in treatment for hepatocellular carcinoma (HCC). However, the optimal threshold of AFP response is still unknown, especially in atezolizumab and bevacizumab (Atez/Bev) treatment.

Usefulness of neutrophil-to-lymphocyte ratio in predicting progression and survival outcomes after atezolizumab-bevacizumab treatment for hepatocellular carcinoma.

Non-Achievement of Alanine Aminotransferase Normalization Associated with the Risk of Hepatocellular Carcinoma during Nucleos(t)ide Analogue Therapies: A Multicenter Retrospective Study.

Patients with a chronic hepatitis B virus (HBV) infection who are treated with nucleos(t)ide analogues (NAs) are still at risk for hepatocellular carcinoma (HCC), and it has been clinically questioned whether patients with a high risk of HCC can be identified efficiently. We aimed to clarify the risk factors associated with the development of HCC during NA therapies. A total of 611 chronically HBV-infected patients without a history of HCC, who were treated with NAs for more than 6 months (median 72 months), from 2000 to 2021, were included from 16 hospitals in the Tohoku district in Japan.

Efficacy of hepatitis C virus eradication after curative treatment for hepatocellular carcinoma in patients with advanced hepatocellular carcinoma and decreased hepatic functional reserve: A nationwide, multicentre study by the Japanese Red Cross Liver Study Group.

Improvements in the hepatocellular carcinoma (HCC) recurrence rate and survival have been frequently reported following virus eradication after hepatitis C virus (HCV)-related HCC cure. However, the efficacy of direct-acting antiviral (DAA) therapy in patients who included those with advanced HCC and decreased hepatic functional reserve is unknown. A comparative examination was retrospectively conducted of 141 patients with hepatitis C who started DAA therapy within 1 year after undergoing curative HCC treatment and showed a sustained viral response (SVR) and 327 patients who underwent curative treatment for HCV-related HCC and did not subsequently receive antiviral therapy.

A validation study of after direct-acting antivirals recommendation for surveillance score for the development of hepatocellular carcinoma in patients with hepatitis C virus infection who had received direct-acting antiviral therapy and achieved sustained virological response.

Background And Aim: The pathogenic process underlying the development of hepatocellular carcinoma (HCC) is not yet clear in patients with hepatitis C virus (HCV) who have received direct-acting antiviral (DAA) therapy and achieved sustained virological response (SVR). This study validated a composite predictive model for HCC in these patients.

Methods: This study included 3058 patients in whom HCV was eradicated with DAA therapy.

Time-course changes in liver functional reserve after successful sofosbuvir/velpatasvir treatment in patients with decompensated cirrhosis.

Aim: Direct-acting antivirals (DAAs) are currently available even for patients with decompensated cirrhosis. Reportedly, hepatic functional reserve improved in the short term after achievement of sustained virologic response (SVR). We aimed to clarify the outcomes after achievement of SVR in patients with decompensated cirrhosis who were treated by DAAs in real-world clinical practice.

Hepatocellular Carcinoma Risk Assessment for Patients With Advanced Fibrosis After Eradication of Hepatitis C Virus.

The identification of patients with advanced fibrosis who do not need any further hepatocellular carcinoma (HCC) surveillance after the eradication of hepatitis C is pivotal. In this study, we developed a simple serum-based risk model that could identify patients with low-risk HCC. This was a nationwide multicenter study involving 16 Hospitals in Japan.

Real-world clinical outcomes of sofosbuvir and velpatasvir treatment in HCV genotype 1- and 2-infected patients with decompensated cirrhosis: A nationwide multicenter study by the Japanese Red Cross Liver Study Group.

The real-world virological efficacy and safety of interferon-free direct-acting antiviral (DAA) therapy with sofosbuvir (SOF) and velpatasvir (VEL) were assessed in hepatitis C virus (HCV) genotype 1- and 2-infected patients with decompensated cirrhosis. A total of 65 patients with HCV-related decompensated cirrhosis (Child-Pugh score of 7 points or more) who were treated with the SOF/VEL regimen were enrolled. The sustained virological response (SVR) rate and safety profile were analyzed.
