Seroreversion of hepatitis B surface antigen among subjects with resolved hepatitis B virus infection: A community-based cohort study. J Gastroenterol Hepatol 2021; 36:3239-3246. [PMID: 34318943 DOI: 10.1111/jgh.15640] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Revised: 06/28/2021] [Accepted: 07/22/2021] [Indexed: 12/09/2022]
Abstract
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.

Enhanced enzymatic production of cholesteryl 6'-acylglucoside impairs lysosomal degradation for the intracellular survival of Helicobacter pylori. J Biomed Sci 2021; 28:72.

Abstract
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.

J Formos Med Assoc 2021; 121:1273-1282. [PMID: 34625346 DOI: 10.1016/j.jfma.2021.09.009] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2020] [Revised: 07/21/2021] [Accepted: 09/13/2021] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND/PURPOSE Switching to a tenofovir alafenamide (TAF)-containing regimen has been reported to be associated with body weight gain in human immunodeficiency virus-infected subjects. We aimed to investigate the body weight change and virological, hepatic, and renal outcomes of TAF switching among chronic hepatitis B (CHB) patients. METHODS This retrospective study included 121 CHB patients who were switched to TAF after >12 months of treatment with another nucleot(s)ide analog (NUC). All patients were monitored for 12 months. RESULTS The cohort was mostly Asian (96.7%) with a mean age of 55 years, 72% male, 14% cirrhosis, 21% HBeAg positive, and 75% with prior use of tenofovir disoproxil fumarate. At 12 months after TAF switching, their body weight significantly increased from 66.4 ± 11.8 to 67.8 ± 12.3 kg (p < 0.001), and 21.1% of the subjects had a ≥5% weight gain. Patients without diabetes or hypertension were more likely to have a body weight gain. Meanwhile, the complete viral suppression rate increased significantly from 89.3% to 96.2% (p = 0.016). The rate of alanine aminotransferase normalization also increased significantly from 71.1% to 87.6% (p < 0.001) by local criteria and from 58.7% to 70.2% (p = 0.029) by AASLD criteria. The mean eGFR (mL/min/1.73 m2) did not change (88.2 ± 18.8 vs. 87.2 ± 17.5, p = 0.28). However, for the subgroup with GFR <90 at TAF switching, there was a significant improvement in eGFR (72.9 ± 12.0 vs. 75.7 ± 14.2, p = 0.027). CONCLUSION In real-world NUC-experienced CHB patients, unexpected body weight gain was observed after TAF switching. The mechanism needs to be investigated in the future.

Abstract
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.

Abstract
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.

A Systematic Study of the Stability, Safety, and Efficacy of the de novo Designed Antimicrobial Peptide PepD2 and Its Modified Derivatives Against Acinetobacter baumannii. Front Microbiol 2021; 12:678330. [PMID: 34220763 PMCID: PMC8250858 DOI: 10.3389/fmicb.2021.678330] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Accepted: 05/27/2021] [Indexed: 12/12/2022] Open
Abstract
Searching for new antimicrobials is a pressing issue to conquer the emergence of multidrug-resistant (MDR) bacteria and fungi. Antimicrobial peptides (AMPs) usually have antimicrobial mechanisms different from those of traditional antibiotics and bring new hope in the discovery of new antimicrobials. In addition to antimicrobial activity, stability and target selectivity are important concerns to decide whether an antimicrobial peptide can be applied in vivo. Here, we used a simple de novo designed peptide, pepD2, which contains only three kinds of amino acid residues (W, K, L), as an example to evaluate how the residues and modifications affect the antimicrobial activity against Acinetobacter baumannii, stability in plasma, and toxicity to human HEK293 cells. We found that pepI2 with a Leu→Ile substitution can decrease the minimum bactericidal concentrations (MBC) against A. baumannii by one half (4 μg/mL). A D-form peptide, pepdD2, in which the D-enantiomers replaced the L-enantiomers of the Lys(K) and Leu(L) residues, extended the peptide half-life in plasma by more than 12-fold. PepD3 is 3-residue shorter than pepD2. Decreasing peptide length did not affect antimicrobial activity but increased the IC50 to HEK293 cells, thus increased the selectivity index (SI) between A. baumannii and HEK293 cells from 4.7 to 8.5. The chain length increase of the N-terminal acyl group and the Lys→Arg substitution greatly enhanced the hemolytic activity, hence those modifications are not good for clinical application. Unlike colistin, the action mechanism of our peptides relies on negatively charged lipids rather than lipopolysaccharides. Therefore, not only gram-negative bacteria but also gram-positive bacteria can be killed by our peptides.

Abstract
Uraemic patients undergoing haemodialysis are at high risk of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. We aimed to evaluate the evolutionary seroprevalence of viral hepatitis and the gap in HCV care cascades in this special population by a large-scale surveillance study in Taiwan. Uraemic patients on maintenance haemodialysis from 22 sites (FORMOSA-LIKE group) in 2012 (n = 1,680) and 2019 (n = 2,326) were recruited for this study. The distributions and sequential changes of viral hepatitis markers were analysed. The prevalence of anti-HCV antibody and hepatitis B surface antigen (HBsAg) seropositivity was 13.6% (316/2326) and 11.5% (267/2326), respectively, in 2019 compared with 17.3% (290/1680, P = .002) and 13.6% (229/1680, P = .046), respectively, in 2012. The HCV-viremic rate among anti-HCV-seropositive patients was significantly lower in 2019 than in 2012 (56.3% [178/316] vs. 73.8% [214/290], P < .001). The HCV treatment rate increased from 2.3% (5/217) in 2012 to 21.7% (49/226) in 2019 (P < .001). In the sequential analysis of the 490 patients who participated in both screens, 17 of the 55 HCV-viremic patients became HCV RNA seronegative, including 13 by antivirals and four spontaneously. By contrast, one anti-HCV-seropositive but nonviremic patient became viremic, and six anti-HCV-seronegative patients became anti-HCV-seropositive in 2019. The annual incidence of new HCV was 0.2%/year. Seven HBsAg-seropositive patients experienced HBsAg loss (1.25%/year). Two patients had new anti-HBc seropositivity (new HBV exposure: 0.57%/year). The seroprevalence of viral hepatitis decreased in an 8-year follow-up but remained prevalent, and the treatment of HCV infection was underutilized in uraemic patients. Additional efforts are needed to enhance the HCV treatment uptake of uraemic patients. Clinical Trial IDs: NCT03803410, NCT01766895.

Abstract
The spreading of viral hepatitis among injecting drug users (IDU) is an emerging public health concern. This study explored the prevalence and the risks of hepatitis B virus (HBV), hepatitis C virus (HCV) and hepatitis D virus (HDV) among IDU-dominant prisoners in Taiwan. HBV surface antigen (HBsAg), antibodies to HCV (anti-HCV) and HDV (anti-HDV), viral load and HCV genotypes were measured in 1137(67.0%) of 1697 prisoners. 89.2% of participants were IDUs and none had HIV infection. The prevalence of HBsAg, anti-HCV, dual HBsAg/anti-HCV, HBsAg/anti-HDV, and triple HBsAg/anti-HCV/anti-HDV was 13.6%, 34.8%, 4.9%, 3.4%, and 2.8%, respectively. HBV viremia rate was significantly lower in HBV/HCV-coinfected than HBV mono-infected subjects (66.1% versus 89.9%, adjusted odds ratio/95% confidence intervals [aOR/CI] = 0.27/0.10-0.73). 47.5% anti-HCV-seropositive subjects (n = 396) were non-viremic, including 23.2% subjects were antivirals-induced. The predominant HCV genotypes were genotype 6(40.9%), 1a(24.0%) and 3(11.1%). HBsAg seropositivity was negatively correlated with HCV viremia among the treatment naïve HCV subjects (44.7% versus 72.4%, aOR/CI = 0.27/0.13-0.58). Anti-HCV seropositivity significantly increased the risk of anti-HDV-seropositivity among HBsAg carriers (57.1% versus 7.1%, aOR/CI = 15.73/6.04-40.96). In conclusion, IUDs remain as reservoirs for multiple hepatitis viruses infection among HIV-uninfected prisoners in Taiwan. HCV infection increased the risk of HDV infection but suppressed HBV replication in HBsAg carriers. An effective strategy is mandatory to control the epidemic in this high-risk group.

Abstract
OBJECTIVES Hepatitis C virus (HCV) infection is the leading cause of cirrhosis and hepatocellular carcinoma worldwide. Tzukuan, located in the southwestern area of Taiwan, is an HCV hyperendemic area (>30%). This study aimed to assess the changing epidemiological characteristics of HCV infection and to evaluate the long-term outcomes after the implementation of public health strategies for two decades. DESIGN A population-based retrospective cohort study. SETTING A comprehensive care programme was implemented, namely COMPACT Study, in Tzukuan since 1997. PARTICIPANTS A total of 10 714 residents participated the screening. OUTCOME MEASURES The HCV status, demographic and clinical profiles of the participants were recorded and validated annually from 2000 through 2019. RESULTS The HCV infection prevalence rates were 21.1% (1076/5099) in 2000-2004, 18.8% (239/1269) in 2005-2009, 14.1% (292/2071) in 2010-2014 and 10.3% (234/2275) in 2015-2019 (p for trend test <0.0001). Among them, 1614 underwent repeated tests during the follow-up period. The annual incidence rates were 0.54% in 2005-2009, 0.4% in 2010-2014 and 0.22% in 2015-2019, respectively (p=0.01). In addition to old age, lower education level was a major risk factor for HCV infection across different periods. HCV infection prevalence rate among those illiterates reached 40.9%, followed by 28.5% in those with elementary school level, and <10% in those with high school or higher levels. The major risk factor has shifted from iatrogenic exposure in 2000-2009 to household transmission after 2010. CONCLUSIONS HCV infection has been decreasing and the epidemiological features are changing in the hyperendemic area by continuing education, prevention and treatment strategies.

Concordance of SVR12, SVR24 and SVR durability in Taiwanese chronic hepatitis C patients with direct-acting antivirals. PLoS One 2021; 16:e0245479.

Abstract
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.

Reactivation of fetal hemoglobin (HbF) expression by therapeutic agents has been suggested as an alternative treatment to modulate anemia and the related symptoms of severe β-thalassemia and sickle cell disease (SCD). Hydroxyurea (HU) is the first US FDA-approved HbF inducer for treating SCD. However, approximately 25% of the patients with SCD do not respond to HU. A previous study identified TN1 (1) as a small-molecule HbF inducer. However, this study found that the poor potency and oral bioavailability of compound 1 limits the development of this inducer for clinical use. To develop drug-like compounds, further structure-activity relationship studies on the purine-based structure of 1 were conducted. Herein, we report our discovery of a more potent inducer, compound 13a, that can efficiently induce γ-globin gene expression at non-cytotoxic concentrations. The molecular mechanism of 13a, for the regulation HbF expression, was also investigated. In addition, we demonstrated that oral administration of 13a can ameliorate anemia and the related symptoms in SCD mice. The results of this study suggest that 13a can be further developed as a novel agent for treating hemoglobinopathies, such as β-thalassemia and SCD.

Abstract
Background/Aims Direct‐acting antivirals (DAAs) have been approved for hepatitis C virus (HCV) treatment in patients with end-stage renal disease (ESRD) on hemodialysis. Nevertheless, the complicated comedications and their potential drug-drug interactions (DDIs) with DAAs might limit clinical practice in this special population. Methods The number, class, and characteristics of comedications and their potential DDIs with five DAA regimens were analyzed among HCV-viremic patients from 23 hemodialysis centers in Taiwan. Results Of 2,015 hemodialysis patients screened in 2019, 169 patients seropositive for HCV RNA were enrolled (mean age, 65.6 years; median duration of hemodialysis, 5.8 years). All patients received at least one comedication (median number, 6; mean class number, 3.4). The most common comedication classes were ESRD-associated medications (94.1%), cardiovascular drugs (69.8%) and antidiabetic drugs (43.2%). ESRD-associated medications were excluded from DDI analysis. Sofosbuvir/velpatasvir/voxilaprevir had the highest frequency of potential contraindicated DDIs (red, 5.6%), followed by glecaprevir/pibrentasvir (4.0%), sofosbuvir/ledipasvir (1.3%), sofosbuvir/velpatasvir (1.3%), and elbasvir/grazoprevir (0.3%). For potentially significant DDIs (orange, requiring close monitoring or dose adjustments), sofosbuvir/velpatasvir/voxilaprevir had the highest frequency (19.9%), followed by sofosbuvir/ledipasvir (18.2%), glecaprevir/pibrentasvir (12.6%), sofosbuvir/velpatasvir (12.6%), and elbasvir/grazoprevir (7.3%). Overall, lipid-lowering agents were the most common comedication class with red-category DDIs to all DAA regimens (n=62), followed by cardiovascular agents (n=15), and central nervous system agents (n=10). Conclusions HCV-viremic patients on hemodialysis had a very high prevalence of comedications with a broad spectrum, which had varied DDIs with currently available DAA regimens. Elbasvir/grazoprevir had the fewest potential DDIs, and sofosbuvir/velpatasvir/voxilaprevir had the most potential DDIs.

Abstract
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.

Abstract
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
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
BACKGROUND & AIMS The outcome of HBV infection, including the 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 pre-treatment 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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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
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.

Abstract
OBJECTIVE The treatment outcome of direct-acting antivirals (DAAs) in chronic hepatitis C patients with hepatocellular carcinoma (HCC) is controversial. The current study aimed to address the treatment efficacy and safety of DAAs in patients with curative or active HCC, compared with those of patients without HCC. DESIGN A prospective cohort study SETTING: A medical centre and two regional hospitals in Taiwan PARTICIPANTS: A total of 713 Taiwanese patients (601 non-HCC, 74 curative HCC and 38 active HCC patients) who received standard-of-care DAAs were consecutively enrolled in the study. MAIN OUTCOME MEASUREMENT The primary objective was to determine treatment efficacy, defined as undetectable hepatitis C virus RNA throughout 12 weeks of the post-treatment follow-up period (sustained virological response 12 [SVR12]). RESULTS The overall SVR12 rate was 96.9%. The SVR12 rate was similar between the patients with HCC and those without HCC (95.5% vs 97.2%, p=0.37). The HCC patients were divided into two groups, those with curative HCC and those with viable HCC; a substantially but not significantly lower SVR rate, 92.1% (35/38), was observed in the patients with viable HCC compared with the SVR rate, 97.3% (72/74), in those with curative HCC (p=0.33). Compared with the patients with curative HCC, the patients with viable HCC had a significantly higher proportion of serious adverse events (10.5% vs 1.0%, p=0.002), early treatment discontinuation (10.5% vs 2.8%, p=0.03) and mortality (5.3% vs 0.1%, p=0.008). CONCLUSIONS An equivalently high SVR rate was observed in patients with either past or active HCC compared with those without HCC. The safety concerns in the HCC patients did not compromise treatment efficacy.

Abstract
Essentials Uncertainty remains about antiplatelets for vascular access patency in hemodialysis patients. 95 971 people under hemodialysis were followed in a claims database in Taiwan. Aspirin reduced vascular access failure rate and did not increase major bleeding rate. Clopidogrel, Aggrenox, and warfarin might increase major bleeding rate. SUMMARY: Background Dialysis adequacy is a major determinant of survival for patients with end-stage renal disease. Good vascular access is essential to achieve adequate dialysis. Objectives This study evaluated the impacts of different drugs on the vascular access failure rate of an arteriovenous fistula or an arteriovenous graft and the rate of major bleeding in hemodialysis patients. Patients and methods We studied patients with end-stage renal disease registered in the Taiwan National Health Insurance program from 1 January 1997 to 31 December 2012. A total of 95 971 patients were enrolled in our study. Vascular access dysfunction was defined as the need for thrombectomy or percutaneous angioplasty. Major bleeding was defined as emergency department visits or hospitalization with a primary diagnosis of gastrointestinal bleeding or intracerebral hemorrhage. The adjusted odds ratios between person-quarters with or without antiplatelet or oral anticoagulant use were calculated using a generalized estimating equation. Results The odds ratio of vascular access failure was 0.21 (0.11-0.39) for aspirin, 0.76 (0.74-0.79) for clopidogrel, 0.67 (0.59-0.77) for dipyridamole, 0.67 (0.53-0.86) for Aggrenox and 0.96 (0.90-1.03) for warfarin. The highest odds ratio for intracerebral hemorrhage was 5.33 (1.25-22.72) in younger patients using Aggrenox. The highest odds ratio for gastrointestinal bleeding was 1.34 (1.10-1.64) for clopidogrel. Conclusion Antiplatelet agents, but not warfarin, might reduce the vascular access thrombosis rate. The gastrointestinal bleeding rate was increased in the group using clopidogrel. Aggrenox should be used with caution in young individuals because it might increase the rate of intracerebral hemorrhage.

Association between cryoglobulinemia and liver fibrosis in chronic hepatitis C patients. J Gastroenterol Hepatol 2018; 33:1897-1903. [PMID: 29737561 DOI: 10.1111/jgh.14275] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2018] [Revised: 04/11/2018] [Accepted: 04/23/2018] [Indexed: 01/14/2023]
Abstract
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.
