Background: The aim of the present study was to compare the histological characteristics of livers between chronic hepatitis C (CHC) patients with and without hepatitis B virus (HBV) coinfection. Methods: A total of 336 CHC patients (male/female: 204/132, mean age: 46.1 ± 11.7 years) were enrolled in the study; 32 patients (9.8%) were positive for hepatitis B surface antigen (HBsAg). The histological characteristics of livers were described according to the Knodell and Scheuer scoring system. Results: The proportion of non-intralobular necrosis (score 0) was significantly lower and the mean intralobular necrosis score was higher among CHC patients with HBV coinfection than those without coinfection (43.8% vs 64.5%; 0.84 ± 1.05 vs 0.53 ± 0.89). The epidemiological and virological parameters, and other histological scores (periportal necrosis, portal inflammation, total necroinflammation and fibrosis) were not significantly different between these two groups. Conclusion: Chronic hepatitis C patients with HBV coinfection tend to have more severe intralobular necrosis than those with isolated HCV infection. [ABSTRACT FROM AUTHOR]

Background and Aim: A number of hepatitis C virus (HCV) patients without a rapid virological response (RVR) achieved a sustained virological response (SVR) with peginterferon-α-2a/ribavirin. The aim of this study was to identify factors associated with SVR in non-RVR patients. Methods: Baseline and on-treatment factors were used to explore the prognostic factors for SVR in 113 HCV genotype-1 (HCV-1) and 20 HCV-2 non-RVR patients in two randomized trials. Results: The SVR rate in HCV-1 patients with a complete early virological response (cEVR) and partial early virological response was 91.9% versus 45% ( P < 0.001) and 21.4% versus 10% ( P = 0.62), respectively, after 48 and 24 weeks of treatment. The SVR rate in HCV-2 patients with a cEVR was 90.9% versus 57.1% ( P = 0.25), respectively, after 24 and 16 weeks of treatment. Multivariate analysis showed that cEVR and standard regimen were independently associated with SVR. Viral kinetic study revealed that HCV viral loads < 10 000 IU/mL at week 4 were the best predictor of cEVR for both HCV-1 and HCV-2 non-RVR patients with the accuracy of 81% and 95%, respectively, and also of SVR with the accuracy of 78% and 92%, respectively, in patients receiving standard of care. The most important independent predictors for cEVR were HCV viral loads < 104 IU/mL at week 4, followed by increased ribavirin dose within 12 weeks of treatment. Conclusions: Achieving a cEVR with standard of care is the most important predictor of SVR in non-RVR patients. Week 4 viral loads < 10 000 IU/mL could accurately predict cEVR early and following SVR in non-SVR patients. [ABSTRACT FROM AUTHOR]

Background. The present study evaluated the efficacy and safety of pegylated interferon (PegIFN)/ribavirin treatment in elderly patients with hepatitis C virus (HCV) infection. Methods. Seventy elderly patients with hepatitis C virus (HCV) infection (group A; age, ⩾65 years) and 140 sex- and HCV genotype-matched controls (group B; age, 50-64 years) were allocated to receive a PegIFN-α-2a/ ribavirin standard-of-care regimen. Results. Group A had a significantly higher rate of treatment discontinuation (21.4% vs 6.4%; P=.001) and grade 3 or 4 adverse events (34.3% vs 20%; P=.002) than group B. In intention-to-treat analysis, the sustained virologic response (SVR) rate was substantially lower in group A than in group B (67.1% vs 78.6%; P=.07). The inferiority of the SVR rate in group A was observed among patients with HCV genotype 1 (HCV-1) (51.9% vs 75.9%; P=.03) but not among patients with HCV genotype 2 or 3 (HCV-2/3) (76.7% vs 80.2%; P=.65). Among patients in group A who had a rapid virologic response, those infected with HCV-1 and those infected with HCV- 2/3 had similar SVR rates (80% and 87.9%, respectively). For patients receiving treatment for >80% of its expected duration, SVR rates were similar between the 2 groups (80.4% vs 82.6%, respectively), regardless of viral genotype. Conclusions. Older patients with HCV infection, especially those in the subgroup infected with HCV-1, had a greater frequency of adverse events and poorer adherence to the standard-of-care regimen, which may be the major reason for treatment inferiority.

Background: Polymerase chain reaction (PCR) methods play an essential role in providing data relating to diagnosis, monitoring and treatment of hepatitis C virus (HCV) infection. The real-time reverse transcription PCR (RT-PCR) assay is an established and promising tool in terms of quantifying HCV RNA for clinical application. This study aimed to evaluate the performance characteristics of a real-time RT-PCR-based test in a clinical setting. Methods: Validation and reproducibility tests were performed using a standard panel. Sera from 197 chronic HCV patients were analyzed by the real-time RT-PCR assay and the results were compared with the Versant bDNA3.0 assay (bDNA3.0). Results: The real-time RT-PCR assay showed an acceptable linear response (r2=0.989–0.995) in the serial dilutions regarding genotypes 1b, 2a, 2b and 1b+2a. HCV viral loads were quantifiable in all 197 patients (100%) by the real-time RT-PCR assay and in 194 (98.5%) by the bDNA3.0. HCV RNA quantification values measured by the real-time RT-PCR and bDNA3.0 assays were positively correlated (Pearson's correlation coefficient r=0.734, p<0.001). The real-time RT-PCR assay values were on average 0.13 logs higher than the bDNA3.0 results. The correlation coefficients with genotypes 1b, 2a, 2b and mixed were 0.737, 0.711, 0.791 and 0.766, respectively (p<0.01). Conclusions: The real-time RT-PCR assay showed comparable performance with bDNA3.0 regarding quantification of HCV viral loads with genotype 1 and 2 HCV infections. Clin Chem Lab Med 2008;46:475–80.

To assess the efficacy of 24- or 48-week peginterferon/ribavirin treatment of Taiwanese patients with chronic hepatitis C virus genotype-1b (HCV-1b) infection, and to identify subgroups of patients in whom the 48-week treatment has benefits. Methods: We assigned 60 patients receiving peginterferon-α-2b (80–100 mcg/week) plus ribavirin (1000–1200 mg/day), depending on body weight, for 24 or 48 weeks, with a 3:1 randomization ratio. Results: The sustained virological response (SVR) rate was significantly higher in the 48-week (80.0%, 12/15) than in the 24-week group (48.9%, 22/45, P<0.05). The 60 patients were classified into two subgroups according to the presence of unfavorable baseline predictors: viral loads ≥400 000 IU/ml or a hepatic fibrosis score of 3–4. In 19 patients without an unfavorable predictor, the SVR rate was comparable in the 24-week (78.6%) and 48-week (75.0%) groups; in patients with either unfavorable predictors, the SVR rate was significantly higher in the 48-week (81.1%, 9/11) than in the 24-week group (36.7%, 11/30, P=0.015). The discontinuation rate was significantly higher in the 48-week (20.0%, 3/15) than in the 24-week group (2.2%, 1/45, P<0.05). Conclusion: A 48-week course of peginterferon-α-2b/ribavirin was more effective than a 24-week course in Taiwanese HCV-1b patients, mainly in those with high viral loads and/or advanced hepatic fibrosis.

The G→A transition in the tumor necrosis factor (TNF)- αa promoter region at position -308 (TNF3O8.2) and -238 (TNF238.2) were determined in 141 patients with chronic hepatitis C virus (HCV) infection. Patients received combination therapy with high-dose interferon (IFN)-α and ribavirin for 24 weeks. A total of 100 patients (70.9%) had a sustained virologic response (SVR) after treatment. The TNF3O8.2 allele was independently associated with an SVR, particularly in patients with HCV genotype lb infection and >200,000 IU of HCV RNA/mL in serum. In conclusion, the response to combination therapy with high-dose IFN-α and ribavirin may be associated, at least in part, with host genetic factors. [ABSTRACT FROM AUTHOR]

The immune response of patients with chronic liver disease tends to be lower after receiving their second coronavirus disease 2019 (COVID‐19) vaccine dose, but the effect of a third vaccine dose on their immune response is currently unknown. We recruited 722 patients without previous severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection from three hospitals. The patients received homologous (MMM) and heterologous (AZAZBNT, AZAZM) boosters, where AZ, BNT, and M denoted the AZD1222, BNT162b2, and mRNA‐1273 vaccines, respectively. Serum IgG spike antibody levels were measured at a mean 1.5 ± 0.7 (visit 1) and 5.0 ± 0.5 (visit 2) months after the third vaccine booster. A threshold of 4160 AU/mL was considered significant antibody activity. In both visits, the patients who received the MMM booster had higher anti‐S‐IgG levels than those who received the AZAZBNT and AZAZM boosters. Patients with active hepatocellular carcinoma (HCC) had lower anti‐S‐IgG levels than the control group (761.6 vs. 1498.2 BAU/mL; p = 0.019) at visit 1. The anti‐S‐IgG levels decreased significantly at visit 2. The patients with significant antibody activity had a lower rate of liver cirrhosis with decompensation (0.7% decompensation vs. 8.0% non‐decompensation and 91.3% non‐liver cirrhosis, p = 0.015), and active HCC (1.5% active HCC vs. 3.7% non‐active HCC and 94.7% non‐HCC, p < 0.001). Receiving the MMM booster regimen (OR = 10.67, 95% CI 5.20–21.91, p < 0.001) increased the odds of having significant antibody activity compared with the AZAZBNT booster regimen. Patients with active HCC had a reduced immune response to the third COVID‐19 vaccine booster. These findings underscore the importance of booster vaccinations, especially in immunocompromised patients, with superior efficacy observed with the homologous mRNA‐1273 regimen.

The accuracy of noninvasive seromarkers in predicting liver fibrosis in metabolic dysfunction‐associated fatty liver disease (MAFLD) patients with or without viral hepatitis is elusive. The AST to platelet ratio index (APRI), fibrosis‐4 index (FIB‐4), and NAFLD fibrosis score (NFS) were assessed in 871 MAFLD patients who received elastography in a viral hepatitis‐endemic area. The area under the receiver operating characteristic (AUROC) curve increased substantially with increasing fibrotic stage across the three biomarkers. APRI (AUROC range 0.73–0.80) and FIB‐4 (AUROC range 0.66–0.82) performed better than NFS (AUROC range 0.63–0.75). When patients were divided into viral and non‐viral MAFLD groups, a better AUROC of APRI (range 0.76–0.80) and FIB‐4 (range 0.68–0.78) than NFS (range 0.62–70) existed only in viral MALFD but not in non‐viral MAFLD. Regarding the NFS, the AUROC was higher in non‐viral MAFLD (range 0.69–0.86) and outperformed viral MAFLD at all fibrotic stages. The accuracy in predicting liver fibrosis increased with the advancement of liver disease for the three biomarkers. NFS exerted better diagnostic accuracy in non‐viral than in viral MAFLD patients across different fibrotic stages. The best accuracy was 91.1% using the cutoff value of −9.98 for the NFS in predicting liver cirrhosis in non‐viral MAFLD patients. The APRI and FIB‐4 performed better than the NFS in predicting liver fibrosis in MAFLD as a whole. The suboptimal performance and accuracy of the NFS existed only in viral MAFLD patients. Caution should be taken when assessing the NFS in MAFLD patients with viral hepatitis. [ABSTRACT FROM AUTHOR]

We aimed to investigate the association between air pollution and advanced fibrosis among patients with metabolic associated fatty liver disease (MAFLD) and chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections. A total of 1376 participants who were seropositive for HBV surface antigen (HBsAg) or antibodies to HCV (anti‐HCV) or had abnormal liver function in a community screening program from 2019 to 2021 were enrolled for the assessment of liver fibrosis using transient elastography. Daily estimates of air pollutants (particulate matter ≤2.5 μm in diameter [PM2.5], nitrogen dioxide [NO2], ozone [O3] and benzene) were aggregated into mean estimates for the previous year based on the date of enrolment. Of the 1376 participants, 767 (52.8%) and 187 (13.6) had MAFLD and advanced fibrosis, respectively. A logistic regression analysis revealed that the factors associated with advanced liver fibrosis were HCV viremia (odds ratio [OR], 3.13; 95% confidence interval [CI], 2.05–4.77; p < 0.001), smoking (OR, 1.79; 95% CI, 1.16–2.74; p = 0.01), age (OR, 1.04; 95% CI, 1.02–1.05; p < 0.001) and PM2.5 (OR, 1.10; 95% CI, 1.05–1.16; p < 0.001). Linear regression analysis revealed that LSM was independently correlated with PM2.5 (β: 0.134; 95% CI: 0.025, 0.243; p = 0.02). There was a dose‐dependent relationship between different fibrotic stages and the PM2.5 level (the PM2.5 level in patients with fibrotic stages 0, 1–2 and 3–4: 27.9, 28.4, and 29.3 μg/m3, respectively; trend p < 0.001). Exposure to PM2.5, as well as HBV and HCV infections, is associated with advanced liver fibrosis in patients with MAFLD. There was a dose‐dependent correlation between PM2.5 levels and the severity of hepatic fibrosis. [ABSTRACT FROM AUTHOR]

Background and aims: Fatty liver disease (FLD) is associated with several metabolic derangements. We conducted a retrospective cross-sectional and longitudinal study to evaluate the role of FL severity in the risk of new-onset and co-existing hypertension (HTN) and diabetes mellitus (DM). Methods: The cross-sectional cohort consisted of 41,888 adults who received health checkups in a tertiary hospital of Taiwan from 1999 to 2013. Of them, 34,865 without HTN and/or DM at baseline and within 1 year after enrollment were included as a longitudinal cohort (mean, 6.45 years for HTN; 6.75 years for DM). FL severity based on the degree of hepatic steatosis was assessed by ultrasound sonography. Results: In cross-sectional cohort, 22,852 (54.6%) subjects had FL (18,203 [43.46%] mild FL and 4,649 [11.10%] moderate/severe FL); 13.5% (n = 5668) had HTN; and 3.4% (n = 1411) had DM. Moderate/severe FL and mild FL had significantly higher risks of existing HTN (adjusted odds ratio/95% confidence interval [CI] 1.59/1.43–1.77 and 1.22/1.13–1.32, respectively). In longitudinal cohort, 3,209 and 822 subjects developed new-onset HTN and DM, respectively (annual incidence, 14.3 and 3.5 per 1000 person-years; 10-year cumulative incidence, 14.35% and 3.89%, respectively). Moderate/severe and mild FL had significantly higher risks of new-onset HTN (adjusted hazard ratio [aHR]/CI 1.54/1.34–1.77 and 1.26/1.16–1.37, respectively) and DM (aHR/CI 5.88/4.44–7.81 and 3.22/2.56–4.07, respectively). Resolved FL during follow-up decreased the risk of HTN and/or DM. Conclusions: Patients with FL are at high risk of prevalent and incident HTN and/or DM. The risk increases with the severity of FL.

Background and Aim: The prevalence of metabolic dysfunction‐associated fatty liver disease (MAFLD) and its interplay with hepatitis B virus (HBV) and hepatitis C virus (HCV) in terms of liver disease severity is elusive. Methods: A mass surveillance program was conducted in a viral hepatitis endemic area. The objective was to identify MAFLD/non‐MAFLD subjects with advanced liver disease. Results: Two thousand two hundred and forty‐two (41.7%) of the 5378 subjects were identified as having MAFLD, and 375 (7.0%) had advanced liver disease. The proportions of anti‐HCV and HBsAg seropositivity were 19.3% and 9.7%, respectively. The proportions of advanced fibrosis in subjects with non‐viral hepatitis (NBNC), HBV and HCV infection were 2.8%, 5.7% and 23.4%, respectively. Subjects with MAFLD had a significantly higher proportion of advanced fibrosis (8.7% vs 5.7%, P < 0.001). Factors associated with advanced fibrosis included age (odds ratio [OR]/95% confidence interval [CI]: 4.8/3.7–6.0, P < 0.001), male sex (OR/CI: 1.3/1.0–1.7, P = 0.019), anti‐HCV seropositivity (OR/CI: 5.9/4.6–7.5, P = 0.019), MAFLD‐lean metabolic dysregulation (MS) (OR/CI: 2.6/1.3–5.2, P = 0.005; compared with the non‐MAFLD group) and MAFLD‐diabetes (OR/CI: 1.5/1.1–2.1, P = 0.008; compared with the non‐MAFLD group). MAFLD did not aggravate liver disease severity in patients with viral hepatitis. However, among NBNC subjects, factors associated with advanced liver disease included MAFLD‐lean MS group (OR/CI: 9.1/2.4–34.6, P = 0.001; compared with non‐MAFLD group) and MAFLD‐DM group (OR/CI: 2.0/1.2–3.2, P = 0.004; compared with non‐MAFLD group). Conclusions: MAFLD patients with diabetes and metabolic dysregulation had a higher risk of advanced liver disease. The effect was more significant in non‐viral hepatitis subjects in a community level. [ABSTRACT FROM AUTHOR]

Patients with serious mental illness have a higher risk of hepatitis C virus (HCV) infection but suboptimal HCV care. The current study aimed to facilitate HCV treatment uptake by implementing an integrated outreach care model. Multidisciplinary outreach screening followed by HCV reflex testing and onsite treatment for schizophrenia patients was accomplished through the coordination of nongovernmental organizations, remote specialists, and local care providers. The objective was microelimination effectiveness, defined as the multiplication of the rates of anti‐HCV antibodies screening, accurate HCV RNA diagnosis, treatment allocation, treatment completion, and sustained virological response (SVR12; no detectable HCV RNA throughout 12 weeks in the post‐treatment follow‐up period). A total of 1478 of the 2300 (64.3%) psychiatric patients received HCV mass screening. Seventy‐three (4.9%) individuals were seropositive for anti‐HCV antibodies. Of the 73 anti‐HCV seropositive patients, all (100%) received HCV reflex testing, and 29 (37.7%) patients had HCV viremia. Eight patients (34.8%) had advanced liver disease, including 3 with liver cirrhosis and 2 with newly diagnosed hepatocellular carcinoma. Twenty‐three of the 24 (95.8%) patients who stayed in the healthcare system received and completed 8 weeks of glecaprevir/pibrentasvir treatment and post‐treatment follow‐up without significant DDIs or adverse events. The SVR12 rate was 100%. The microelimination effectiveness in the current study was 61.6%. Individuals with serious mental illness are underserved and suffer from diagnostic delays. This patient‐centered and integrated outreach program facilitated HCV care in this marginalized population. [ABSTRACT FROM AUTHOR]

Background The World Health Organization has established interim guidance for hepatitis C virus (HCV) elimination. We aimed to prove the concept of "treatment as prevention" by conducting a prospective HCV elimination program for hemodialysis (HD) patients. Methods A universal HCV screen was launched in 22 HD centers in 2019. HCV-viremic patients were linked to care with direct-acting antivirals (DAAs). The second screen was performed in 2021 to evaluate the effect of link-to-care in lowering the prevalence of HCV viremia and the incidence of HCV new/re-infections. Results Of 2336 patients enrolled in the first screening in 2019, 320 (13.7%) were seropositive for anti-HCV and 181 (7.7%) were HCV-viremic. Of 152 patients successfully linked to treat with DAA, 140 (92.1%) patients achieved a sustained virological response. Of them, 1733 patients participated in the second surveillance. Five anti-HCV-negative patients experienced anti-HCV seroconversion. Of 119 DAA-cured patients and 102 spontaneous HCV clearance patients, none had HCV reinfection. The annual incidence of HCV new infection was 0.1%. Sixty-one of the 620 (9.8%) newly enrolled patients were anti-HCV-seropositive in the second survey. The overall HCV-viremic rate decreased from 7.7% in 2019 to 0.6% (15/2353) in 2021. At the institutional level, 45.5% (10/22) eradicated HCV and 82% (18/22) of HD units had no HCV new infections or reinfections. Conclusions The link-to-care project proved the concept of "treatment as prevention" by which HCV microelimination helps to prevent reinfection and new infections in the HD population. Trial registration: ClinicalTrials.gov identifier: NCT03803410 and NCT03891550. [ABSTRACT FROM AUTHOR]

Unawareness of hepatitis B virus (HBV) infection and lack of surveillance may serve as major barriers to HBV control and contributors to severe hepatocellular carcinoma (HCC) at presentation. This study evaluated the risk of HBV unawareness and its relationship with HCC severity. This retrospective study was conducted in a tertiary hospital in Taiwan. Patients with HBV‐related HCC diagnosed from 2011 to 2021 were enrolled. The demographic, clinical, and HCC characteristics were collected and compared between patients with HBV unawareness and awareness with and without surveillance. Of 501 HBV‐related HCC patients enrolled, 105 (21%) patients were unaware of HBV infection at the time of HCC diagnosis. Patients with HBV unawareness were significantly younger and had poorer liver function than those with HBV awareness. Patients with HBV unawareness also had a significantly higher rate of detectable HBV DNA and an advanced stage of HCC. Ninety‐one (23%) of the HBV‐aware patients did not receive regular surveillance. Patients with HBV unawareness and awareness without surveillance shared similar clinical characteristics with more severe HCC status. Further regression analysis demonstrated that HBV awareness with periodic surveillance was associated with early stage HCC. Meanwhile, we observed that there was no change in the proportion of HBV awareness over the past 10 years. Patients with surveillance also had better HCC survival than patients without surveillance or unawareness. HBV unawareness and lack of regular surveillance correlated with advanced HCC at presentation. Efforts to improve HBV education, disease awareness, and HCC surveillance are needed.

Background/Aims: Vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is one of the best policies to control COVID-19 pandemic. The serological response to COVID-19 vaccination in Taiwanese patients with different comorbidities is elusive. Methods: Uninfected subjects who received 3 doses of mRNA vaccines (BNT162b2 [Pfizer-BioNTech, BNT] and mRNA-1273 [Moderna]), viral vector-based vaccines (ChAdOx1-S (AZD1222, AZ) or protein subunit vaccines (Medigen COVID-19 vaccine) were prospectively enrolled. The SARS-CoV-2-IgG spike antibody level was determined within three months after the 3rd dose of vaccination. The Charlson Comorbidity Index (CCI) was applied to determine the association between vaccine titers and underlying comorbidities. Results: A total of 824 subjects were enrolled in the current study. The proportions of CCI scores of 0–1, 2–3 and > 4 were 52.8% (n = 435), 31.3% (n = 258) and 15.9% (n = 131), respectively. The most commonly used vaccination combination was AZ–AZ–Moderna (39.2%), followed by Moderna–Moderna–Moderna (27.8%). The mean vaccination titer was 3.11 log BAU/mL after a median of 48 days after the 3rd dose. Factors associated with potentially effective neutralization capacity (IgG level ≥ 4160 AU/mL) included age ≥ 60 years (odds ratio [OR]/95% confidence interval [CI]: 0.50/0.34–0.72, P < 0.001), female sex (OR/CI: 1.85/1.30–2.63, P = 0.001), Moderna–Moderna-based vaccination (compared to AZ–AZ-based vaccination, OR/CI: 6.49/3.90–10.83, P < 0.001), BNT–BNT-based vaccination (compared to AZ–AZ-based vaccination, OR/CI: 7.91/1.82–34.3, P = 0.006) and a CCI score ≥ 4 (OR/CI: 0.53/0.34–0.82, P = 0.004). There was a decreasing trend in antibody titers with increasing CCI scores (trend P < 0.001). Linear regression analysis revealed that higher CCI scores (β: − 0.083; 95% CI: − 0.094–0.011, P = 0.014) independently correlated with low IgG spike antibody levels. Conclusions: Subjects with more comorbidities had a poor serological response to 3 doses of COVID-19 vaccination. [ABSTRACT FROM AUTHOR]

Hepatitis C virus (HCV) eradication through antivirals ameliorates metabolic profiles. The changes in 2‐h plasma glucose (2HPG) levels by oral glucose tolerance test (OGTT), in chronic hepatitis C (CHC) patients who receive directly acting antivirals (DAAs) was elusive. Five hundred and thirty‐three CHC patients who achieved sustained virological response (SVR, undetectable HCV RNA throughout 3 months after the end‐of‐treatment) by DAAs were consecutively enrolled. Pre‐ and posttreatment 2HPG levels and glucose status were compared. The proportion of patients with improved, worsened, and stable 2HPG was 14.4% (n = 77), 18.6% (n = 99), and 67.0% (n = 357), respectively. Compared with patients with worsening 2HPG, those with improved 2HPG had a higher proportion of cirrhosis (45.5% vs. 24.2%, p = 0.004) and higher pretreatment 2HPG levels (175.3 vs. 129.5 mg/dl, p < 0.001). High baseline 2HPG was independently associated with improved 2HPG in multivariate analysis (odds ratio [OR]/CI: 1.05/1.03–1.06, p < 0.001). When baseline 2HPG was not taken into account, cirrhosis was the only factor independently associated with improved 2HPG status (OR/CI: 2.58/1.29–5.15, p = 0.007). Linear regression analysis revealed that factors independently correlated to changes in 2HPG levels were female sex (β: 8.78; 95% CI:2.34, 15.22; p = 0.01), diabetes (β: −27.72; 95% CI: −50.16, −5.28; p = 0.02), liver cirrhosis (β: −8.91; 95% CI: −16.75, −2.20; p = 0.01), and genotype 1 of HCV (β: −0.12; 95% CI: −15.19, −2.43; p = 0.01). 2HPG improved after HCV eradication by DAAs, particularly in cirrhotic patients.

Understanding the barriers and tackling the hurdles of hepatitis C virus (HCV) care cascades is key to HCV elimination. The current study aimed to investigate the rates of disease awareness, link‐to‐care, and treatment uptake of HCV in a hyperendemic area in Taiwan. Tzukuan residents from 2000 to 2018 were invited to participate in the questionnaire‐based interviews for HCV. The rates of disease awareness, accessibility, and anti‐HCV therapy were evaluated in anti‐HCV‐seropositive participants. Among 10,348 residents, 1789 (17.3%) were anti‐HCV seropositive. Of these 1789 anti‐HCV‐seropositive participants, data of 594 participants from questionnaire‐based interviews in 2005–2018 were analyzed for HCV care cascades. Overall, 24.9% of anti‐HCV‐seropositive HCV participants had disease awareness, 53.9% of aware participants had accessibility, and 79.8% of assessed participants had received HCV treatment, with a community effectiveness of 10.7%. HCV prevalence decreased over time, from 21.2% in the early cohort to 9.3% in the recent cohort. Disease awareness increased over time, from 15.6% to 41.7%, with the community effectiveness increasing from 1.3% to 28.8%. Lower education levels and normal liver biochemistry were associated with a lower rate of disease awareness. Notably, 68% of participants with abnormal liver biochemistry and 69% of those with advanced fibrosis (FIB‐4 > 3.25) were unaware of their HCV disease. We demonstrated huge gaps in disease awareness, link‐to‐care, and treatment uptake in the HCV care cascade in an HCV‐hyperendemic area, even in the initial era of direct‐acting antiviral agents. There is an urgent need to overcome these hurdles to achieve HCV elimination. [ABSTRACT FROM AUTHOR]

Background: High dosage and longer duration of antiviral treatment has been suggested to treat cryoglobulinemia patients. We aimed to investigate the efficacy of antiviral treatment in cryoglobulinemia patients and analyze the associated factors of persistent cryoglobulinemia. Methods: Totally 148 patients after completion of anti-HCV treatment were enrolled in our study. Serum cryoglobulinemia precipitation was assessed and analyzed for the associated factors after antiviral therapy. Results: Fifty-one (34.5%) out of 148 patients were positive for serum cryoglobulinemia after completion of antiviral therapy. In multivariate analysis, advanced fibrosis (Odds Ratio [OR]– 4.13, 95% Confidence Interval [95% CI]– 1.53–11.17, p = 0.005) and platelet counts (OR-0.98, 95% CI– 0.97–0.99, p = 0.010) were independently and significantly associated with persistent cryoglobulinemia. The factors associated with the persistent cryoglobulinemia in SVR patients were advanced fibrosis (OR-1.93, 95% CI– 1.02–3.65, p = 0.041) and platelet count (OR-0.98, 95% CI– 0.96–0.99, p = 0.041) by multivariate analysis. Multivariate logistic regression analysis showed persistent (OR-4.83, 95% CI– 1.75–13.36, p = 0.002) was significantly associated with advanced fibrosis in patients with cryoglobulinemia follow up after antiviral therapy. Conclusions: The prevalence of the persistent cryoglobulinemia is 34.5% after completing antiviral therapy and it is associated with advanced fibrosis, also HCV clearance. [ABSTRACT FROM AUTHOR]

The role of Wisteria floribunda agglutinin‐positive Mac‐2 binding protein (WFA+‐M2BP) in the prediction of disease severity in nonalcoholic fatty liver disease (NAFLD) remains elusive. This study evaluated the performance of WFA+‐M2BP in predicting fibrosis in patients with NAFLD. A total of 80 patients with biopsy‐proven nonalcoholic steatohepatitis (NASH) were enrolled. Serum WFA+‐M2BP levels were measured using standard methods. The fibrosis‐4 (FIB‐4) index was also measured. The mean values of WFA+‐M2BP were 1.0, 1.0, 0.8, and 2.2 in Metavir fibrosis stage F0, F1, F2, and F3‐4, respectively (linear trend p = 0.005). The optimal cut‐off value of WFA+‐M2BP in predicting advanced fibrosis (F3‐4) was 1.37 cut‐off index (COI), yielding the sensitivity, specificity, positive predictive value (PPV), negative predictive value, and accuracy of 75.0, 79.4, 39.1, 94.7, and 78.7%, respectively (p < 0.001). Combining WFA+‐M2BP with FIB‐4 significantly increased the diagnostic performance for advanced fibrosis, yielding specificity, PPV, and accuracy of 100, 100, and 93%, respectively. The significant factors predicting advanced liver fibrosis in the multivariate regression analysis were WFA+‐M2BP ≥ 1.37 COI (OR/confidence interval [CI]: 9.49/1.63–55.21, p = 0.01) and FIB‐4 ≥ 2.80 (OR/CI: 38.18/4.89–297.93, p = 0.001). Monitoring WFA+‐M2BP is suitable for noninvasive assessment of liver fibrosis in NASH patients, particularly in combination with FIB‐4. [ABSTRACT FROM AUTHOR]

Background and aims: The itemization difference of patient-reported outcome (PRO) in hepatitis patients with different etiologies remains elusive in Asia. We aimed to assess the characteristics and the difference of health-related quality of life (HRQoL) in chronic hepatitis B (CHB), chronic hepatitis C (CHC), and non-alcoholic fatty liver disease (NAFLD) patients. Methods: We conducted the study in an outpatient setting. The 36-Item Short Form Health Survey (SF-36) was completed by the patients upon the initial diagnosis and recruitment for a long-term follow-up purpose. The PRO results were also assessed by disease severity. Results: There were 244 patients (198 males) of CHB, 54 patients (29 males) of CHC, and 129 patients (85 males) of NAFLD, respectively. CHC patient had the mean score of 67.1 ± 23.3 in physical component summary (PCS) of the SF-36 health survey, which was significantly lower than CHB patients (76.4 ± 19.5), and NAFLD patients (77.5 ± 13.7), respectively (p = 0.001). The significantly lower performance of PCS in CHC patients was mainly attributed to the lower performance in physical functioning and bodily pain components. Higher fibrosis 4 index scores were significantly associated with lower PCS scores in all patient groups. There was no significant difference of mean mental component summary (MCS) between groups. However, NAFLD patients had significantly lower mental health scores than other groups (p = 0.02). Conclusions: The significant difference of HRQoL exists in hepatitis patients with different etiologies. Disease severity leads to a lower PCS performance. [ABSTRACT FROM AUTHOR]

Key points: Question: Is hepatitis C virus (HCV) micro-elimination achievable at the hospital level with the structured strategies? Findings: The multidirectional program included the HCV reflex test for hospital personnel, outpatient surveillance, a call-back system, and surveillance of cancer patients prior to chemotherapy. Through the plans of the study, 97.8% of the HCV-viremic patients successfully received linkage-to-treat. The results of each strategy sufficiently met the 2030 elimination goal by the World Health Organization (WHO). Meaning: HCV micro-elimination is achievable at the hospital level based on patient safety, staff occupational safety and infection control. Background and aims: Scarce data are available on in-hospital hepatitis C virus (HCV) micro-elimination strategies. This pilot study was prospectively conducted to assess the outcomes of HCV in-hospital micro-elimination program (HCV-HELP) in a single center in Taiwan. Methods: The study included the HCV reflex test for plans A (hospital personnel), B (outpatient surveillance), C (a call-back system for anti-HCV+ patients), and D (surveillance of cancer patients prior to chemotherapy). The primary outcome measurement was that > 80% of eligible patients were enrolled in linkage-to-treat; the secondary outcome measurement was the surveillance efficacy. Results: We recruited 930, 6072, 2376 and 233 participants into plans A, B, C, and D, respectively, from Oct 2020 to May 2021. The anti-HCV-seropositivity prevalences were 0.22% for plan A, 4.3% for B, and 3.9% for D. Two staff members were identified as HCV-viremic in plan A; these staff members successfully achieved a sustained virological response (SVR). We identified 39, 95 and 2 HCV-viremic patients in plans B, C, and D, respectively. Of these 138 HCV-viremic patients, 135 (97.8%) received direct-acting antiviral therapy, and 134 achieved SVR. Two 4-month phases were stratified to compare efficacies in the liver clinic. In the late phase, the adjusted number of HCV-viremic patients was 4.36/10,000 outpatient visits (90/200,689), which was 3.18-fold higher than that of the early phase (1.37/10,000 outpatient visits [30/212,658], odds ratio 3.18; 95% confidence interval 2.10–4.81, p < 0.0001). Conclusion: HCV micro-elimination is achievable at the hospital level as per the structured HCV-HELP study. [ABSTRACT FROM AUTHOR]

Background and Aims: Regorafenib has demonstrated its survival benefit for unresectable hepatocellular carcinoma (uHCC) patients in a phase III clinical trial. We aimed to assess the efficacy and tolerability of regorafenib and the predictors of treatment outcomes in Taiwanese patients. Methods: We analyzed the survival, best overall response, predictors of treatment outcomes, and safety for uHCC patients who had tumor progression on sorafenib therapy and received regorafenib as salvage therapy between March 2018 and November 2020. Results: Eighty‐six patients with uHCC were enrolled (median age, 66.5 years; 76.7% male). The median regorafenib treatment duration was 4.0 months (95% confidence interval [CI], 3.6–4.6). The most frequently reported adverse events were hand‐foot skin reaction (44.2%), diarrhea (36.0%), and fatigue (29.1%). No unpredictable toxicity was observed during treatment. The median overall survival (OS) with regorafenib was 12.4 months (95% CI, 7.8–17.0) and the median progression‐free survival (PFS) was 4.2 months (95% CI, 3.7–4.7). Of 82 patients with regorafenib responses assessable, 4 patients (4.9%) achieved a partial response, and 33 (40.2%) had stable disease, leading to a disease control rate (DCR) of 45.1% (n = 37). Patients possessing baseline AFP < 400 ng/ml exhibited a markedly longer median OS, median PFS, and higher DCR compared with their counterparts (15.7 vs. 8.1 months, 4.6 vs. 3.7 months, 60.9% vs. 27.5%, respectively). Despite possessing high baseline AFP levels, patients with early AFP response (>10% reduction at 4 weeks or >20% reduction at 8 weeks after regorafenib administration) exhibited comparable treatment outcomes to those with baseline AFP < 400 ng/ml. Conclusions: The results of this real‐world study verified the tolerability and efficacy of regorafenib treatment for uHCC patients who failed prior sorafenib therapy, especially for those with lower baseline AFP levels or with early AFP response.

Background and Aim: Hepatitis B virus (HBV) surface antigen (HBsAg) seroreversion usually occurs during immunosuppressive therapy. The risk and factors of HBsAg seroreversion from resolved HBV infection in the general population remained unclear. Methods: This retrospective study enrolled subjects with resolved HBV infection and who had received at least two times of screening in a longitudinal community screening program. HBsAg, hepatitis B surface antibody (anti‐HBs), and hepatitis C virus antibody (anti‐HCV) were tested every time in all subjects. The primary endpoint was HBsAg seroreversion. Results: Of the 7630 subjects enrolled, 5158 (67.6%) subjects had positive anti‐HBs at baseline. HBsAg seroreversion occurred in 84 subjects during 42 815‐person‐year follow‐up with an annual incidence of 0.2% and a 10‐year cumulative risk of 1.9%. Anti‐HBV treatment‐experienced subjects had a significantly higher risk of HBsAg seroreversion than anti‐HBV treatment‐naive subjects (83/310 [26.8%] vs 1/7320 [0.01%], P < 0.001). Lower rates of positive anti‐HBs and anti‐HCV were observed in anti‐HBV treatment‐experienced subjects who developed HBsAg seroreversion. Both positive anti‐HBs (hazard ratio/95% confidence interval: 0.56/0.348–0.903, P = 0.017) and positive anti‐HCV (hazard ratio/95% confidence interval: 0.08/0.030–0.234, P < 0.001) were independent factors of HBsAg seroreversion in anti‐HBV treatment‐experienced subjects. Less than 5% of the HBsAg seroreverters had clinical hepatitis flare at HBsAg seroreversion. The HBsAg titer was low, and only transient reappeared in most of the HBsAg seroreverters. Conclusions: Subjects with resolved HBV infection were at a minimal risk of HBsAg seroreversion, unless with prior anti‐HBV treatment experience. Fortunately, even with a reappearance of HBsAg, it was transient and clinically non‐relevant. [ABSTRACT FROM AUTHOR]

Background: During autophagy defense against invading microbes, certain lipid types are indispensable for generating specialized membrane-bound organelles. The lipid composition of autophagosomes remains obscure, as does the issue of how specific lipids and lipid-associated enzymes participate in autophagosome formation and maturation. Helicobacter pylori is auxotrophic for cholesterol and converts cholesterol to cholesteryl glucoside derivatives, including cholesteryl 6ʹ-O-acyl-α-d-glucoside (CAG). We investigated how CAG and its biosynthetic acyltransferase assist H. pylori to escape host-cell autophagy. Methods: We applied a metabolite-tagging method to obtain fluorophore-containing cholesteryl glucosides that were utilized to understand their intracellular locations. H. pylori 26695 and a cholesteryl glucosyltransferase (CGT)-deletion mutant (ΔCGT) were used as the standard strain and the negative control that contains no cholesterol-derived metabolites, respectively. Bacterial internalization and several autophagy-related assays were conducted to unravel the possible mechanism that H. pylori develops to hijack the host-cell autophagy response. Subcellular fractions of H. pylori-infected AGS cells were obtained and measured for the acyltransferase activity. Results: The imaging studies of fluorophore-labeled cholesteryl glucosides pinpointed their intracellular localization in AGS cells. The result indicated that CAG enhances the internalization of H. pylori in AGS cells. Particularly, CAG, instead of CG and CPG, is able to augment the autophagy response induced by H. pylori. How CAG participates in the autophagy process is multifaceted. CAG was found to intervene in the degradation of autophagosomes and reduce lysosomal biogenesis, supporting the idea that intracellular H. pylori is harbored by autophago-lysosomes in favor of the bacterial survival. Furthermore, we performed the enzyme activity assay of subcellular fractions of H. pylori-infected AGS cells. The analysis showed that the acyltransferase is mainly distributed in autophago-lysosomal compartments. Conclusions: Our results support the idea that the acyltransferase is mainly distributed in the subcellular compartment consisting of autophagosomes, late endosomes, and lysosomes, in which the acidic environment is beneficial for the maximal acyltransferase activity. The resulting elevated level of CAG can facilitate bacterial internalization, interfere with the autophagy flux, and causes reduced lysosomal biogenesis. [ABSTRACT FROM AUTHOR]

Background: The efficacy and safety of insulin sensitizer in Asians with non-alcoholic steatohepatitis (NASH) remain elusive. Aims: The double-blind, randomized, placebo-controlled trial was conducted aiming to investigate the efficacy and safety of pioglitazone in NASH patients. Methods: A total of 90 NASH patients (66 males, age = 44.1 ± 12.7 years) were prospectively randomized into oral pioglitazone 30 mg/day (Arm A) or placebo (Arm B) for 24 weeks. The primary endpoint was the efficacy of pioglitazone in reducing inflammation and liver fat at end-of-treatment (EOT). NASH resolution/improvement without fibrosis worsening was also evaluated. Results: At EOT, there was a significantly decline of alanine aminotransferase (86.9 ± 34.3 to 45.7 ± 35.8 IU/L, p = 0.003) level in Arm A patients. In intention-to-treat analysis among 66 patients who completed paired biopsies, The NAFLD activity score (NAS) of 30 Arm A patients significantly decreased from 4.27 ± 1.14 at baseline to 2.53 ± 1.63 at EOT (p < 0.0001), whereas there was no significant change in patients of Arm B (3.94 ± 1.41 vs 3.94 ± 1.51, p = 1.0). NASH improvement without worsening of fibrosis was achieved in 46.7% (14/30) patients in Arm A, compared to 11.1% (4/36) patients in Arm B (p = 0.002). Liver fat content reduced (20.2 ± 9.0 to 14.3 ± 6.9%, p < 0.0001) on MRI–PDFF in Arm A compared to their counterparts. No significant difference of adverse events occurred between groups. Conclusions: A 24-week pioglitazone treatment was well-tolerated and effective in improving liver histology and reducing liver steatosis in Asian NASH patients.

Background and Aim: Hemodialysis patients are at increased risk of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. Both HBV and HCV infections lead to risks of end‐stage liver diseases and extrahepatic manifestations. This study aimed to investigate hepatic and extrahepatic comorbidities in hemodialysis patients with HBV or HCV infections compared with those without viral hepatitis. Methods: A total of 1910 hemodialysis patients, including 159 HCV viremic patients (HCV group), 217 seropositive for HBV surface antigen (HBsAg, HBV group) and 1534 seronegative for both anti‐HCV and HBsAg (non‐B and non‐C [NBNC] group), from 23 hemodialysis centers were enrolled. Comorbidities were classified into 10 categories by the International Classification of Diseases‐10th Revision. Results: Among the 1910 patients, the mean age was 64.6 years, and 52.7% were male patients. A total of 1834 (96%) patients had at least one comorbidity, and the mean number of comorbidities was 2.9 ± 1.5 per person. The three most common comorbidities were hypertension, diabetes, and ischemic heart diseases. The mean number of comorbidities per person was significantly higher in the HCV group (3.3 ± 1.7) than in the HBV (2.7 ± 1.5, P < 0.001) and NBNC groups (2.9 ± 1.5, P = 0.004), mainly due to the higher prevalence of ischemic heart disease, respiratory disorders, and mental/behavioral disorders. The HBV and NBNC groups exhibited comparable burdens of comorbidities. Conclusions: Hemodialysis patients had a high prevalence of multiple comorbidities. Hemodialysis patients with HCV exhibited a higher burden of comorbidities, especially ischemic heart diseases, respiratory disorders, and mental/behavioral disorders, than HBV and NBNC patients did.

Background/Aims: Undetectable HCV RNA 12 weeks after the end of treatment (SVR12) has been the valid efficacy endpoint in the era of direct-acting antivirals (DAAs). Its concordance with SVR4 and SVR24 and long-term durability is unknown in Taiwanese chronic hepatitis C (CHC) patients. Methods: A total of 1080 CHC patients who received all-oral DAAs and an achieved end-of-treatment virological response (EOTVR), defined as undetectable HCV RNA at the end of therapy, were consecutively enrolled. HCV RNA was monitored 4, 12, and 24 weeks after EOT. Patients who achieved SVR24, defined as undetectable HCV RNA 24 weeks after EOT, were followed annually for assessing SVR durability. Results: Eleven (1.02%) patients experienced HCV RNA reappearance after EOT. The most frequent timing of RNA reappearance was observed at SVR4 (n = 7), followed by SVR12 (n = 3) and SVR 24 (n = 1). The positive predictive value (PPV) and negative predictive value (NPV) of SVR4 in predicting SVR12 were 99.7% and 100%, respectively, whereas the PPV and NPV of SVR12 in predicting SVR24 were 99.9% and 100%, respectively. Pyrosequencing confirmed delayed relapse rather than reinfection for the patient who had detectable HCV RNA at SVR24. Among 978 patients who achieved SVR24, after a median follow-up period of 17.3±8.2 months, the SVR durability is 100% up to a 4-year follow-up. Conclusion: Achievement of SVR12 provides excellent durability of HCV seroclearance after DAA therapy. On-demand HCV RNA beyond SVR12 should be recommended for patients with unexplainable abnormal liver function or high-risk behaviors. [ABSTRACT FROM AUTHOR]

Whether patients with advanced hepatocellular carcinoma (aHCC) benefit from hepatitis C virus (HCV) eradication is uncertain. We aimed to investigate whether a survival benefit was conferred by HCV eradication in aHCC patients. This retrospective cohort study enrolled 168 HCV‐infected aHCC patients from April 2013 to January 2019. All patients were treated with sorafenib. Endpoints included overall survival (OS), progression free survival (PFS), and time to liver decompensation. Patients with undetectable HCV RNA exhibited reduced aspartate aminotransferase and alpha fetoprotein levels, as well as an attenuated proportion of aHCC at initial diagnosis but increased albumin and mean sorafenib daily dosing. Patients with undetectable HCV RNA exhibited significantly longer OS compared to patients with detectable or unknown HCV RNA, which was an independent factor of OS (HR: 0.56, 95% CI: 0.350‐0.903, P =.017). Patients with undetectable HCV RNA also presented a trend for longer PFS (HR 0.68, 95% CI: 0.46‐1.00, P =.053). The survival benefit was considered with respect to the significantly prolonged time to Child‐Pugh B scores in patients with undetectable HCV RNA (HR 0.59, 95% CI: 0.38‐0.92, P =.020). Patients with detectable HCV RNA at sorafenib initiation who further received direct acting antiviral therapy also had significantly longer OS (HR 0.11, 95% CI: 0.02‐0.81, P =.030) and PFS (HR 0.23, 95% CI: 0.06‐0.99, P =.048). In conclusion, abolishing HCV viremia preserves liver function and confers a survival benefit in advanced HCC patients on sorafenib treatment. [ABSTRACT FROM AUTHOR]

Background: The accurate assessment of liver fibrosis among hemodialysis patients with chronic hepatitis C (CHC) is important for both treatment and for follow up strategies. Applying the non-invasive methods in general population with viral hepatitis have been successful but the applicability of the aminotransferase/platelet ratio index (APRI) or the fibrosis-4 index (FIB-4) in hemodialysis patients need further evaluation. Materials and methods: We conducted a prospective, multi-center, uremic cohort to verify the applicability of APRI and FIB-4 in identifying liver fibrosis by reference with the standard transient elastography (TE) measures. Results: There were 116 CHC cases with valid TE were enrolled in our analysis. 46 cases (39.6%) were classified as F1, 35 cases (30.2%) as F2, 11 cases (9.5%) as F3, and 24 cases (20.7%) as F4, respectively. The traditional APRI and FIB-4 criteria did not correctly identify liver fibrosis. The optimal cut-off value of APRI was 0.28 and of FIB-4 was 1.91 to best excluding liver cirrhosis with AUC of 76% and 77%, respectively. The subgroup analysis showed that female CHC hemodialysis patients had better diagnostic accuracy with 74.1% by APRI. And CHC hemodialysis patients without hypertension had better diagnostic accuracy with 78.6% by FIB-4. Conclusions: This study confirmed the traditional category level of APRI and FIB-4 were unable to identify liver fibrosis of CHC hemodialysis patients. With the adjusted cut-off value, APRI and FIB-4 still showed suboptimal diagnostic accuracy. Our results suggest the necessary of TE measures for liver fibrosis in the CHC uremic population.

Hepatitis C virus (HCV) eradication deteriorates lipid profiles. Although HCV eradication may reduce the risk of vascular events as a whole, whether deteriorated lipid profiles increases the risk of cardio‐cerebral disease in certain patients is elusive. Serial lipid profiles were measured before, during, at and 3 months after the end of direct‐acting antivirals (DAAs) therapy, and annually thereafter in chronic hepatitis C patients who achieved a sustained virological response (SVR, undetectable HCV RNA at posttreatment week 12). The primary end‐point was the occurrence of the events. A total of 617 patients were included, with a mean follow‐up period of 26.8 months (range: 1‐65 months). The total cholesterol and low‐density lipoprotein cholesterol (LDL‐C) levels increased significantly from treatment week 4 to 2 years after treatment. Logistic regression analysis revealed that the factors independently associated with a significant cholesterol increase included age (odds ratio [OR]/95% confidence intervals [CIs]:1.02/1.006‐1.039, P =.007) and smoking (OR/CI:3.21/1.14‐9.02, P =.027). Five patients developed cardio‐cerebral diseases during 1376 person‐years follow‐up period. Compared to patients without vascular events, a significantly higher proportion of those with vascular events experienced an LDL‐C surge >40% (80% vs 19.9%, P =.001). Cox‐regression analysis revealed that an LDL‐C surge >40% was the only factor predictive of vascular events (HR/CI: 15.44/1.73‐138.20, P =.014). Dyslipidemia occurred after HCV eradication, and it was associated with the risk of cardio‐cerebrovascular diseases. Attention should also be paid to the extrahepatic consequence beyond liver‐related complications in the post‐SVR era. [ABSTRACT FROM AUTHOR]

Background and Aims: The features of non-viral, nonalcohol hepatocellular carcinoma (NBNC-HCC) remain elusive. The aim of this study was to investigate this clinical characteristics and overall survival of NBNC-HCC compared to hepatitis B- (HBV-HCC) and hepatitis C-related (HCV-HCC) HCC.Methods: We analyzed the etiologies, fibrosis stages, clinical data, and outcomes of newly diagnosed patients with HCC.Results: A total of 1777 HCC patients were recruited, including 332 patients with NBNC-HCC, 682 patients with HBV-HCC, 680 patients with HCV-HCC, and 83 patients with HBV/HCV HCC. Patients with NBNC-HCC were older (69.9 ± 11.9 years). Patients with NBNC-HCC exhibited a higher prevalence of diabetes (43.9%) compared to the HBV-HCC (27.1%, p < 0.05) and HCV-HCC (30.2%, p < 0.05) groups. Compared to patients from the viral-related HCC groups, patients with NBNC-HCC exhibited a significantly lower fibrosis stage. NBNC-HCC patients exhibited a higher proportion of Barcelona Clinic Liver Cancer (BCLC) classification stage C and stage D compared to patients from the HBV-HCC and HCV-HCC groups. With a mean of 2.33 ± 2.31 years of follow-up, the median survival of patients with NBNC-HCC was 1.75 (95% CI 1.33-2.17) years, which was significantly lower than that of patients with HBV-HCC (p = 0.041) and HCV-HCC (p < 0.001).Conclusions: Patients with NBNC-HCC have a higher risk of diabetes than patients with HCC of viral etiologies. Although patients with NBNC-HCC exhibited a milder fibrosis stage, their more advanced HCC stages and worse overall survival should be taken into consideration in clinical care.

Background and Aim: Hepatitis C virus eradication via the use of antivirals ameliorates metabolic profiles. The changes in serum uric acid (SUA) levels in chronic hepatitis C patients who receive antivirals are not well understood. We aimed to address this issue by comparing the SUA changes before and after the achievement of a sustained virological response (which is defined as hepatitis C virus RNA seronegativity at 12 weeks after the end of treatment). Methods: Two hundred and thirteen sustained virological response patients who were treated by directly acting antivirals were consecutively enrolled. Pretreatment and post‐treatment SUA levels were compared. Hyperuricemia was defined as a uric acid level > 7.0 mg/dL in men and > 6.0 mg/dL in women. Results: The SUA levels significantly decreased after treatment, as compared to the pretreatment levels (5.6 ± 1.5 vs 6.0 ± 1.7 mg/dL, respectively; P < 0.001). The proportion of hyperuricemia incidences significantly decreased after treatment (25.8% vs 35.7%, respectively; P = 0.001). The improvement was only observed in patients with a fibrosis‐4 index (FIB‐4) < 6.5 (25.7% vs 37.1%, P = 0.001) but not in those patients with a FIB‐4 ≧ 6.5 (26.3% vs 28.9%, P = 1.00). A multivariate analysis revealed that the factor that was associated with significantly decreased SUA levels was FIB‐4 < 6.5 (odds ratio [OR]/95% confidence interval [CI]: 3.22/1.04–9.95, P = 0.04) and estimated glomerular filtration rate < 60 mL/min/1.73 m2 (OR/CI: 4.34/1.94–9.73, P < 0.001). There existed a trend of a higher proportion of patients with significant SUA improvement along with the decrement of FIB‐4 (29.7%, 25%, and 10.5% in patients with FIB‐4 < 3.25, 3.25–6.5, and > 6.5, respectively; trend P = 0.03). Conclusions: SUA levels were significantly decreased in chronic hepatitis C patients after viral eradication. The improvement was particularly enhanced in patients with mild liver disease.

Background and Aim: Ribavirin (RBV) remains crucial in difficult‐to‐cure chronic hepatitis C patients receiving directly acting antivirals (DAAs). The current study aimed to address whether RBV enhanced early viral kinetics in patients with DAAs. Methods: Hepatitis C virus (HCV) genotype‐1b patients were allocated to daclatasvir/asunaprevir +weight‐based RBV (1000–1200 mg/day) for 12–24 weeks. HCV RNA levels were compared at day 1, week 1, week 2, and week 4 of treatment. Results: The sustained virological response rate was 100% (67/67) and 96.7% (59/61) in the RBV and non‐RBV group, respectively. The HCV RNA levels at treatment week 2 (W2) were significantly lower in the RBV group than in the non‐RBV group (0.42 ± 0.81 log IU/mL vs 0.79 ± 1.03 log IU/mL, P = 0.04). Among the intermediate responders who remained to have detectable RNA after W1 of treatment, patients with RBV had a significantly higher rate of undetectable HCV RNA (71.4% vs 36.0%, P = 0.003) and lower HCV RNA level at W2 (0.55 ± 0.89 log IU/mL vs 1.32 ± 1.04 log IU/mL, P = 0.001). A more significant magnitude of HCV RNA reduction was also noted from baseline to day 1 (3.15 ± 0.38 log IU/mL vs 2.80 ± 0.70 log IU/mL, P = 0.009) and W1 to W2 (1.40 ± 0.65 log IU/mL vs 0.88 ± 0.78 log IU/mL, P = 0.007) in the RBV group compared to the non‐RBV group among the intermediate responders. Logistic regression analysis revealed that adding RBV independently predicted undetectable HCV RNA at W2 (odds ratio/confidence interval: 4.74/1.54–14.57, P = 0.007) in the intermediate responders. Conclusions: Adding RBV to DAAs improved early viral kinetic, in particular, for intermediate responders. [ABSTRACT FROM AUTHOR]

Sorafenib is currently the first‐line therapy for advanced hepatocellular carcinoma (aHCC) patients. However, the outcomes and prognostic factors of sorafenib therapy have not been well investigated. We aimed to investigate the pretreatment factors and outcomes among Taiwanese aHCC patients receiving sorafenib treatment. A total of 347 patients with aHCC and well‐compensated liver cirrhosis (Child‐Pugh A) status receiving sorafenib were consecutively enrolled from March 2013 through December 2016. Pre‐treatment clinical data and viral hepatitis markers were collected and analyzed with their outcomes. The primary endpoint of the study was overall survival. The factors associated with overall survival were also investigated. The median overall survival of all the patients was 238 days (range, 9‐1504 days) with a 1‐year overall survival of 43.2%. Positive hepatitis B surface antigen and absence of portal vein thrombosis (PVT) were independent factors associated with better overall survival. The median duration of sorafenib therapy was 93.0 days (range, 4‐1504 days). After stopping sorafenib, the median survival was 93.0 days (range, 1‐1254 days). The 1‐year survival after stopping sorafenib was 21.2%. In chronic hepatitis B patients, total bilirubin level was the only factor associated with overall survival. Hepatitis C antibody RNA negativity, tumor size, PVT, and white blood cell count were the independent factors associated with survival among those chronic hepatitis C patients. There were different prognostic factors stratified by viral etiologies in aHCC patients receiving sorafenib. Viral eradication increased survival in chronic hepatitis C patients.

Background: We aimed to investigate the long-term outcomes in hepatitis B (HBV)/hepatitis C virus (HCV) dual-infected patients after anti-HCV therapy.Methods: A total of 192 HBV/HCV dual-infected patients who had received pegylated interferon treatment were recruited. The investigation outcomes included HBV DNA ≥2000 IU/mL, with or without alanine aminotransferase (ALT) ≥2-fold the upper limit of normal, and hepatitis B surface antigen (HBsAg) seroclearance.Results: Four (2.1%) patients developed early HBV reactivation before the end of treatment. Fifty (26.6%) of the remaining patients had an episode of HBV DNA ≥2000 IU/mL in a mean follow-up of 68.8 months. The risk was 4.6 per 100 person years. Only 19 (10.1%) patients developed concomitant ALT flare with oral HBV antiviral therapy; the risk was 1.7 per 100 person years. Despite HBV flare, 67 (34.9%) patients had a favorable outcome of HBsAg seroclearance. The probability was 5.7 per 100 person years. A pretreatment HBV DNA level of 300 IU/mL served as an independent predictor for all the outcomes. The combined pretreatment HBV DNA level and HCV response further enhanced the prediction of HBV flare and HBsAg seroclearance.Conclusions: A pretreatment HBV DNA level of 300 IU/mL predicts HBV flare and HBsAg seroclearance after anti-HCV therapy.

Background and Aim: The prevalence of mixed cryoglobulinemia is 15–50% in chronic hepatitis C (CHC) patients, and these patients are in an increased risk of liver fibrosis and cirrhosis, but it is controversial. This study aimed to reveal the prevalence of mixed cryoglobulinemia in Asian population and to determine the relationship between presence of serum cryoglobulinemia and liver fibrosis in CHC patients with or without liver biopsy. Methods: In total, 2255 treatment‐naïve patients retrospectively enrolled in our study. Serum cryoglobulinemia precipitation, liver biopsy, and four indexes of fibrosis (FIB4) were assessed to detect the associated factors. Results: Three hundred sixty‐four (32%) out of 1135 liver biopsy patients and 341 (30.4%) out of 1120 non‐biopsy patients were positive for serum cryoglobulinemia. Multivariate analysis revealed that male gender, hepatitis C virus RNA, platelet and advanced fibrosis (odds ratio [OR] 1.40, 95% confidence interval [CI] 1.05–1.87, P = 0.021) were significantly associated with the presence of cryoglobulinemia in the liver biopsy proven patients. The presence of serum cryoglobulinemia (OR 1.43, 95% CI 1.04–1.96, P = 0.026) was associated with advanced liver fibrosis (F3 and F4) by multivariate logistic regression analysis. In patients without liver biopsy, FIB4 (OR 1.72, 95% CI 1.30–2.27, P = 0.0001) was associated with the presence of serum cryoglobulinemia, and also cryoglobulinemia (OR 1.74, 95% CI 1.32–2.30, P = 0.0001) was associated with high FIB4 (≥ 3.25) patients. Conclusion: The prevalence of the presence of serum cryoglobulinemia is 30.4–32% in CHC patients and associated with advanced fibrosis in liver biopsy proven patients and high‐FIB4 (≥ 3.25) patients without liver biopsy.

Background and Aim Hepatitis B virus (HBV) may reactivate when treating chronic hepatitis C (CHC) with direct acting antivirals (DAA). We aim to investigate the risk of HBV reactivation during DAA therapy. Methods Chronic hepatitis C patients receiving pan-oral DAA therapy from December 2013 to August 2016 were evaluated. Fifty-seven patients that had a past HBV infection (negative hepatitis B surface antigen [HBsAg] and positive hepatitis B core antibody) and seven patients that had a current HBV infection (positive HBsAg) were enrolled. Serum HBV and hepatitis C virus (HCV) markers were regularly measured. The endpoints were the HCV sustained virological response (SVR) and the HBV virological/clinical reactivation. Results The overall SVR12 rate was 96.9%, and two patients, one with positive HBsAg, had a relapse of HCV. No episodes of HBV virological reactivation were observed among the patients with a past HBV infection. For the seven patients with a current HBV infection, HBV virological reactivation was found in four (57.1%) of the seven patients. Clinical reactivation of HBV was observed in one patient with pretreatment detectable HBV DNA and recovered after entecavir administration. For the other three patients with HBV virological reactivation, the reappearance of low level HBV DNA without clinical reactivation was observed. HBsAg levels demonstrated only small fluctuations in all the patients. Conclusions There was a minimal impact of hepatitis B core antibody seropositivity on HCV efficacy and safety. For CHC patients with current HBV infection, the risk of HBV reactivation was present, and monitoring the HBV DNA level during therapy is warranted. [ABSTRACT FROM AUTHOR]

Background: The impact of additional extra-hepatic primary cancer (EHPC) on the outcomes of patients with hepatocellular carcinoma (HCC) remains uncertain. Methods: We retrospectively analyzed the cancer registration database from a tertiary hospital in Southern Taiwan. Patients who were diagnosed with HCC from 2008 to 2012 were enrolled. Overall survival (OS), HCC-specific survival and recurrence after curative therapy were analyzed and compared between the patients with and the patients without EHPC. Results: EHPC was found in 121/1506 (8.0%) patients. HCC patients with EHPC were older, more likely to be classified as Child-Pugh A, less likely to have viral hepatitis B or C, more likely to be single, had early stage HCC and received curative therapy for HCC. The OS did not significantly differ between the patients with and without EHPC(p = 0.061). However, significantly higher HCC-specific survival was observed in patients with EHPC (p<0.001), and a higher rate of non-HCC mortality was demonstrated in patients with EHPC (54.4% vs 9.3%). The subgroup analysis revealed better OS in patients with EHPC who were older than 65, had viral hepatitis B or C, had non-stage 1 HCC, had non-early stage BCLC and received non-curative therapy. Conversely, patients with HCC stage 1 who received curative therapy exhibited worse OS if they also had EHPC. The analysis of recurrence after curative therapy showed no difference between the two groups. Conclusions: Our results implied that EHPC did not affect OS, but HCC-related survival was better in patients with EHPC. Based on these findings, the management of additional primary cancer is warranted. [ABSTRACT FROM AUTHOR]
