Metabolic management after sustained virologic response in elderly patients with hepatitis C virus: A multicenter study.

AIMS: Hepatocellular carcinoma (HCC) develops even in patients with hepatitis C virus (HCV) eradication by direct-acting antiviral agents. Fatty liver and metabolic dysfunction are becoming major etiologies of HCC. We aimed to evaluate the impact of metabolic dysfunction-associated steatotic liver disease (MASLD), a new definition of steatotic liver disease, on the development of HCC after HCV eradication. METHODS: We enrolled 1280 elderly patients with HCV eradication and no history of HCC. We evaluated α-fetoprotein (AFP), Fibrosis-4 index and MASLD after 24 weeks of sustained virological response. Decision tree analysis was used to investigate factors associated with HCC development after HCV eradication. RESULTS: A total of 86 patients (6.7%) developed HCC during the follow-up period (35.8 ± 23.7 months). On multivariate analysis, serum AFP level (HR 1.08, CI 1.04-1.11, P = 0.0008), Fibrosis-4 index (HR 1.17, CI 1.08-1.26, P = 0.0007), and MASLD (HR 3.04, CI 1.40-6.58, P = 0.0125) at 24 weeks of sustained virological response were independent factors associated with HCC development. In decision tree analysis, the initial classifier for HCC development was AFP ≥7 ng/mL. However, in patients with AFP <7 ng/mL, MASLD, rather than Fibrosis-4 index, was the classifier for HCC development. No significant difference was observed in the cumulative incidence of HCC between patients with AFP ≥7 ng/mL and patients with AFP <7 ng/mL and MASLD. CONCLUSION: MASLD at 24 weeks of sustained virological response is a risk factor for HCC development in elderly patients with HCV eradication. Additionally, decision tree analysis revealed that MASLD was associated with HCC development, even in patients with serum AFP levels <7 ng/mL.

A combination of hepatic encephalopathy and body mass index was associated with the point of no return for improving liver functional reserve after sofosbuvir/velpatasvir treatment in patients with hepatitis C virus-related decompensated cirrhosis.

AIMS: The real-world efficacy of sofosbuvir/velpatasvir treatment for patients with hepatitis C virus-related decompensated cirrhosis is unclear. We aimed to identify factors that improve liver functional reserve after treatment. METHODS: This was a multicenter retrospective study of 12-week sofosbuvir/velpatasvir treatment. A total of 48 patients with Child-Pugh (CP) class B or C were enrolled at 11 institutions. We evaluated changes in liver functional reserve at 24 weeks post-treatment. RESULTS: At baseline, 40 and eight patients were CP class B and C, respectively. The overall rate of sustained virologic response 12 weeks post-treatment was 95.8% (46/48). Serum albumin, alanine aminotransferase and α-fetoprotein levels, and the FIB-4 index were significantly improved post-treatment (P < 0.05). Among patients who achieved sustained virologic response 12 weeks post-treatment, those with CP class A increased from 0 to 24 patients (56%) at 24 weeks post-treatment. In multivariate analysis, body mass index (BMI) ≥25 was an independent factor that inhibited CP class improvement (P < 0.05). In decision tree analysis, after treatment, the initial divergent variable for CP class improvement was hepatic encephalopathy, followed by serum sodium level and BMI. CONCLUSION: Sofosbuvir/velpatasvir treatment improved the liver functional reserve in patients with hepatitis C virus-related decompensated cirrhosis at 24 weeks post-treatment. However, BMI ≥25 inhibited improvement in CP class. Additionally, decision tree analysis revealed that a combination of hepatic encephalopathy, serum sodium levels, and BMI were diversity profiles associated with no improvement in liver functional reserve after the treatment.

Hepatitis C Virus Elimination Using Direct Acting Antivirals after the Radical Cure of Hepatocellular Carcinoma Suppresses the Recurrence of the Cancer.

It remains unclear whether hepatocellular carcinoma (HCC) recurrence in hepatitis C virus (HCV)-infected patients can be suppressed by the elimination of the virus using direct-acting antivirals (DAAs) after radical HCC treatment. We evaluated the sustained inhibitory effect of DAAs on HCC recurrence after curative treatment. This multicenter retrospective study included 190 HCV-positive patients after radical treatment for early-stage HCC. Patients were classified into the DAA treatment group (n = 70) and the non-DAA treatment group (n = 120) after HCC treatment. After propensity score matching (PSM), 112 patients were assessed for first and second recurrences using the Kaplan-Meier method and analyzed using a log-rank test. The first recurrence rates at 1 and 3 years were 3.6% and 42.1% in the DAA treatment group and 21.7% and 61.9% in the non-DAA treatment group, respectively (p = 0.0026). Among 85 patients who received radical treatment, the second recurrence rate at 3 years was 2.2% in the DAA treatment group and 33.9% in the non-DAA treatment group (p = 0.0128). In HCV-positive patients with early-stage HCC, the first and second recurrences were suppressed by DAA therapy after radical treatment, suggesting that the inhibitory effect of DAA therapy on HCC recurrence was sustained.

Evaluation of Resistance-Associated Substitutions in NS5A Using Direct Sequence and Cycleave Method and Treatment Outcome with Daclatasvir and Asunaprevir for Chronic Hepatitis C Genotype 1.

BACKGROUND: The aim of this study was to evaluate the efficacy of daclatasvir plus asunaprevir therapy in patients infected with hepatitis C virus and determine its relevance to resistant variants. METHODS: A total of 629 consecutive patients infected with hepatitis C virus genotype 1 were assessed. Daclatasvir (60 mg/day) plus asunaprevir (200 mg/day) was given for 24 weeks. The virological responses and resistance-associated substitutions of hepatitis C virus mutants were examined by the direct sequence and cycleave methods were evaluated. RESULTS: Overall, 89.4% (555/621) of patients exhibited a sustained virological response (SVR). The SVR rates in the patients with wild type, mixed, and mutant type Y93 by direct sequencing were 92.5% (520/562), 70.3% (26/37), and 42.9% (9/21), respectively. The SVR rates in the patients with 100%, 90%, 80%-30%, and 20%-0% Y93 wild by the cycleave method were 93.4% (456/488), 88.2%(30/34), 56.0%(14/25), and 36.8%(7/19), respectively. In contrast, the SVR rates for the wild type and mixed/mutant type L31 by direct sequencing were 90.2% (534/592) and 72.4% (21/29), respectively. In the multivariate analyses, the wild type Y93, no history of simeprevir therapy, the wild type L31, and low HCV RNA level were independent factors of SVR. CONCLUSION: NS5A resistance-associated substitutions, especially Y93H, were major factors predicting the SVR. Although direct sequencing can predict the SVR rate, the cycleave method is considered to be more useful for predicting the SVR when used in combination.

The importance of a prior psychiatric examination in pegylated interferon and ribavirin combination treatment for chronic hepatitis C.

UNLABELLED: Some patients receiving pegylated interferon and ribavirin treatment for chronic hepatitis C are forced to discontinue the treatment due to psychiatric disorders. We performed a retrospective study to evaluate whether pre-treatment psychiatric examinations could increase successful completion rates for this treatment. METHODS: A total of 535 patients who started pegylated interferon-α-2b and ribavirin treatment at 6 hospitals affiliated with our hospital were included in this study. The patients were divided into two groups. Those who had visited a psychiatric clinic before treatment were Group A (N=223), and those who did not visit a psychiatric clinic before treatment were Group B (N=312). We analyzed the rate of discontinuation due to psychiatric disorders in the two groups. RESULTS: The rate of discontinuation due to psychiatric disorders in Group A was found to be significantly lower than that of Group B (1.8% (4/223) vs. 6.1% (19/312), P=0.035). In Group A, 6.1% (4/65) discontinued the treatment due to psychiatric disorders, while the comparable rate in Group B was 27% (19/68) (P=0.0004). Among patients who presented with psychiatric symptoms during treatment, the rate of treatment completion was significantly higher in Group A than in Group B (69.2% (18/26) vs. 5.0% (1/20), P=0.0067). In patients with a history of psychiatric symptoms, no discontinuation due to psychiatric disorder was observed in Group A. CONCLUSIONS: A psychiatric examination before pegylated interferon and ribavirin treatment was found to positively contribute to the successful completion of the treatment.

Association of exogenous insulin or sulphonylurea treatment with an increased incidence of hepatoma in patients with hepatitis C virus infection.

BACKGROUND: Diabetes mellitus is frequently seen in hepatitis C patients and is often treated with antidiabetic agents that increase serum insulin levels. Because insulin is a growth-promoting hormone, antidiabetic agents could pose a risk for hepatocellular carcinoma (HCC). AIM: The aim of this study was to investigate an association between antidiabetic therapies and the incidence of HCC in hepatitis C patients with diabetes mellitus. METHODS: A nested case-control study was conducted. Participants were recruited from a cohort study, in which patients with hepatitis C were consecutively registered. Participants were assigned to an HCC group (n=138) or a non-HCC group (n=103). To identify independent factors, variables including use of antidiabetic agents were analysed by logistic regression analysis. RESULTS: Besides ageing, being male, cirrhosis and hypoalbuminaemia, use of exogenous insulin and a second-generation sulphonylurea were significant independent factors associated with an incidence of HCC [odds ratio (OR) 2.969, 95% confidence interval (CI) 1.293-6.819, P<0.0103 and OR 6.831, 95% CI 1.954-23.881, P<0.0026 respectively). In stratified analyses, the impact of these antidiabetic agents was more evident in patients who were non-cirrhotic than in those who were cirrhotic. CONCLUSIONS: Exogenous insulin and a second-generation sulphonylurea were independent variables associated with an incidence of HCC in hepatitis C patients with diabetes mellitus. This association was evident in patients who were non-cirrhotic. To verify a causal relationship between these antidiabetic agents and the development of HCC, a prospective cohort study is required.

Markedly prolonged jaundice from simultaneous infection with hepatitis E virus and leptospira.

We treated a patient simultaneously infected with hepatitis E virus and Leptospira interrogans, both acquired in China. Severe hyperbilirubinemia required nearly 200 days to resolve, transminase elevation showed a fluctuating course, and liver biopsy specimens showed fibrosis unusual for hepatitis E. Leptospirosis appeared to have altered the course of hepatitis E virus infection in this patient, even though infection with Leptospira was cleared with antibiotics by 50 days after the onset of the hepatitis symptoms.
