dynamics of HBsAg and HBV virological reactivation, among patients coinfected with HCV receiving direct-acting antivirals (DAAs) remains unclear. Thus, we aimed to analyze HBV-related outcomes in these patients. Methods: Serial HBsAg and HBV DNA levels were measured in 79 HBV/HCV-coinfected patients receiving DAAs (13 receiving anti-HBV nucleot(s)ide analog [NUC] therapy simultaneously). The endpoints included HBsAg dynamics and seroclearance, HBV reactivation (HBV DNA >1 log increase or >100 IU/ml if undetectable at baseline) and HBV-related clinical reactivation. Results: HBsAg levels declined from a median of 73.3 IU/ml at baseline to 16.2 IU/ml at the end-of-DAA treatment and increased to 94.1 IU/ml at 12 months post-treatment. During a mean 11.1-months of follow-up, 8 (10.1%) patients experienced HBsAg seroclearance and 30 (38.0%) HBV reactivation (12-month cumulative incidence, 10.3% and 40.4%, respectively). Patients with pre-treatment HBsAg <= 10 IU/ml had a significantly higher rate of HBsAg seroclearance (hazard ratio [HR] 8.52; 95% CI 1.048-69.312) and lower risk of HBV reactivation than those with pre-treatment HBsAg >10 IU/ml (HR 2.88; 95% CI 1.057-7.844) in multivariate analyses. Six patients (4 cirrhotics) not receiving NUC therapy experienced HBV-related clinical reactivation; 3 of the 4 cirrhotics developed liver failure and 2 died despite immediate NUC therapy. Compared to untreated HBV-monoinfected patients, HBV/HCV-coinfected patients without NUC prophylaxis had a similar rate of HBsAg seroclearance, but a significantly higher risk of HBV reactivation following DAA therapy (HR 6.59; 95% CI 2.488-17.432). Conclusions: DAA-treated HBV/HCV-coinfected patients had significantly higher rates of HBV seroclearance, particularly among those with low pre-treatment HBsAg titer, but were at higher risk of HBV reactivation, particularly among those with higher pretreatment HBsAg titer. Prophylactic anti-HBV therapy is essential for cirrhotic patients, irrespective of baseline HBV DNA levels. Lay summary: We studied outcomes relating to hepatitis B virus (HBV) in patients coinfected with both hepatitis B and C. Patients receiving direct-acting antiviral treatment for hepatitis C were more likely to experience seroclearance (or functional cure of HBV), but were also more likely to experience HBV reactivation, which can lead to hepatitis, liver failure and death. In coinfected cirrhotic patients being treated for HCV, prophylactic treatment for HBV is mandatory. (C) 2020 European Association for the Study of the Liver. Published by Elsevier B.V.

Hepatitis C virus (HCV) infections can cause permanent liver-related diseases, including hepatocellular carcinoma (HCC). Low mortality and incidence of HCC have been observed in patients with chronic hepatitis C undergoing direct-acting antiviral therapy. Tumor suppressive let-7 family members are down-regulated in HCC. The present study, therefore, aimed to investigate whether expression levels for the full spectrum of let-7 family members (let-7a, 7b, 7c, 7d, 7e, 7f, 7g, 7i, and miR-98) in the circulatory system are useful as surveillance biomarkers for liver-related diseases to monitor treatment efficacy during HCV infection. To this end, we measured the levels of mature circulating let-7 family members using quantitative reverse transcription-PCR in 236 patients with HCV infection, and 147 age- and sex-matched controls. Using hierarchical cluster analysis and principal component analysis, three clusters were obtained after measuring expression levels of let-7 family members in the patients and controls. Cluster 1 included let-7a/d/e/g, Cluster 2 comprised let-7b and let-7i, and Cluster 3 comprised let-7c/f/miR-98. Let-7b/c/g represented the three clusters and showed the best survival response to liver cancer when analyzed with respect to patient data. Therefore, considering the circulating levels of let7 b/c/g as representatives of the let-7 family may facilitate effective monitoring of liver-related disease.

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.

Background: Hepatitis C virus (HCV) is the most common viral infection among illicit drug users in the world. Although intervention of needle and syringe program and opioid substitution therapy had engaged to prevent HCV infection, the prevalence of HCV infection does not seem to decline. The aim of this study was to estimate the risk of HCV infection in injecting drug users (IDUs) and noninjecting drug users (NIDUs) receiving opioid substitution therapy. Methods: We recruited 1179 heroin-dependent patients (age: 20-66 years) under opioid substitution therapy from 2012 to 2015 in a Psychiatric Center, Southern Taiwan. The data of HCV, hepatitis B virus and HIV infection and liver biochemical examination were obtained. We used multivariate logistic regression analysis to predict the risk of HCV infection. Results: There were 93.1% of IDUs and 68.1% of NIDUs positive for HCV infection. In IDUs, HIV infection, age of heroin initiation, duration and dose of heroin use, frequency of detoxification, and number of criminal conviction were significantly associated with HCV infection. In NIDUs, snort/sniff heroin exhibited a significantly increased risk of HCV infection. Intravenous injecting (odds ratio [OR] = 23.10, 95% CI = 8.04-66.40, p < 0.001), intravenous injecting combined snort/sniff (OR = 12.95, 95% CI = 3.90-42.97, p < 0.001), and snort/sniff (OR = 4.14, 95% CI = 1.30-13.18, p = 0.016) were significantly associated with increased risk of HCV infection compared with smoking. The trend was significant (p for trend <0.001). Conclusion: In Taiwan, IDUs had harmful characteristics compared with NIDUs and both had extremely high prevalence of HCV infection. We provided evidence that snort/sniff is a possible way of leak in HCV infection despite needle-syringes supplement program been provided. Opioid substitution therapy program should include HCV assessment and treatment in the new direct-acting antiviral therapy era.

Background and Aim The serial serologic changes of hepatitis D virus (HDV) infection among chronic hepatitis B virus (HBV) infected patients who received oral nucleotide/nucleoside analogues are elusive. Methods Serum anti-HDV and HDV RNA among chronic hepatitis B (CHB) patients were tested at the time of initiating anti-HBV therapy and subsequently during the follow-up period. Results The seropositive rate of anti-HDV and HDV RNA among 2850 CHB patients, was 2.7% and 0.9%, respectively. Factors associated with anti-HDV seropositivity were platelet counts (odds ratio [OR]/95% confidence intervals [CI]: 0.995/0.992-0.999; P = 0.006), HBV DNA levels (OR/CI: 0.81/0.70-0.94; P = 0.005), and hepatitis B e-antigen (HBeAg) seropositivity (OR/CI: 0.22/0.05-0.95; P = 0.04). The only factor associated with HDV RNA positivity among anti-HDV seropositive patients was age (OR/CI: 0.95/0.90-1.00; P = 0.03). The spontaneous clearance rate of serum anti-HDV antibody was 3.0 per 100 person-years with a median follow-up period of 3.5 years (range 2-12 years), whereas the seroclearance rate of HDV RNA was 4.3 per 100 person-years among anti-HDV seropositive patients after a median follow-up period of 6.0 years (range 2-11 years). A baseline anti-HDV titer < 0.5 cut-off index was the only factor predictive of anti-HDV seroclearance (hazard ratio [HR]/CI: 30.11/3.73-242.85; P = 0.001). Conclusions HDV infection was not common among patients treated for HBV in Taiwan. Seroclearance of anti-HDV and HDV RNA did occur over time, albeit the chance is rare.

Background/Purpose: Chronic kidney disease (CKD) has become a worldwide health problem, leading to high morbidity and mortality, and non-alcoholic fatty liver disease (NAFLD) is considered a risk factor for CKD. The aim of this study was to explore the relationship between NAFLD fibrosis score (NFS) and the estimated glomerular filtration rate (eGFR), and identify possible risk factors related to the NFS among Taiwanese subjects. Methods: Subjects were enrolled from the database of the Department of Preventive Medicine of Kaohsiung Municipal Hsiao-Kang Hospital. The eGFR was calculated according to the Taiwanese Modification of Diet in Renal Disease (TMDRD) equation, and the NFS was employed to evaluate the fibrotic level. Results: In total, 11,376 subjects were enrolled in this study, with a mean age of 52.0 +/- 6.81 years, including 4529 (39.8%) males. A fasting sugar level >= 100 mg/dL (OR = 1.70, 95% CI = 1.52-1.87) and an abnormal waist circumference (OR = 1.81, 95% CI = 1.65-1.99) were significant factors associated with NFS (p < 0.05). Trends of a decreasing TMDRD score and an increasing NFS with increasing age were noted (p < 0.05). The NFS was significantly negatively correlated with the TMDRD score (standard coefficients: -0.067, p < 0.001). Conclusion: A higher NFS is associated with an impaired eGFR in Taiwanese subjects. Controlling risk factors, especially fasting sugar level and waist circumference, may be useful in preventing NFS deterioration, which is negatively correlated with the eGFR.

Introduction: Interferon (IFN) had both antiviral and immunomodulatory effects, and was one of the approved treatments for hepatitis B virus (HBV). Herein, we reviewed the pharmacokinetics and pharmacodynamics of pegylated IFN-? (PegIFN-?) for the treatment of HBV. Areas covered: The steady-state serum levels of PegIFN-? were reached within 5 to 8?weeks, and the week 48 mean trough concentrations were approximately 2-fold higher than week 1. There was also no difference of the pharmacokinetics in male or female, healthy volunteers or patients with hepatitis B or C infection. PegIFN-? did not affect the metabolism of the cytochrome P450 (CYP) isozymes, except inhibition of CYP1A2. There was also no pharmacokinetic interaction between PegIFN-? and HBV nucleot(s)ide analogues (NUCs). Forty-eight weeks of PegIFN-? achieved 32% of HBeAg seroconversion, 32-43% of HBV DNA suppression, 41-59% of ALT normalization, and 3% of HBsAg seroconversion rate with a post-treatment durable response up to 80% in the initial responders. Expert opinion: On-treatment HBsAg titer guided the treatment of HBV with PegIFN-?. The recommendation of PegIFN-? and NUC combination or switch remained controversial. New immunotherapeutic agents are now in development. Although, PegIFN-? should continue to play a role in the treatment of HBV.

Background. A 12-week grazoprevir/elbasvir regimen is highly effective against hepatitis C virus genotype 1 (HCV-1) infection. The efficacy of an 8-week regimen for treatment-naive HCV-1-infected patients with mild fibrosis has not been determined. Methods. Treatment-naive HCV-1b-infected patients with mild fibrosis were randomly assigned to receive 8 (n = 41) or 12 (n = 41) weeks of grazoprevir/elbasvir therapy. The primary end point was a sustained virologic response, defined as an HCV RNA level of < 12 IU/mL, at posttreatment week 12 (SVR12). Results. SVR12 was achieved by 87.8% of patients (36 of 41) in the 8-week arm and 100% (41 of 41) in the 8-week arm of the full-analysis population and by 90.0% (36 of 40) and 100% (41 of 41), respectively, in the per-protocol population (all P = .055). In the 8-week arm, a significantly lower SVR12 rate was observed among patients with a high HCV-1b load, defined as >= 1 500 000 IU/mL (79% vs 100%; P =.042), and among those with a baseline Y93H resistance-associated substitution (RAS) frequency of >15% in HCV nonstructural protein 5A (NS5A; 40.0% vs 97.1%; P = .004). Between-group analysis demonstrated that, among patient with a high HCV-1b load and a baseline Y93H RAS frequency of >15%, those in the 8-week arm had a substantially lower SVR12 rate than those in the 12-week arm (40.0% vs 100.0%). All 4 HCV-1b relapses had a Y93H RAS frequency of >99% at posttreatment week 12. Conclusions. Twelve weeks of grazoprevir/elbasvir therapy is highly effective for treatment-naive patients with mild fibrosis. A truncated, 8-week grazoprevir/elbasvir regimen might be applied for those with low viral loads or without a significant NS5A RAS frequency.

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 m(2) (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.
