Diabetes mellitus (DM) and hepatitis C virus (HCV) infection are prevalent diseases globally and emerging evidence demonstrates the bidirectional association between the two diseases. Direct-acting antivirals (DAAs) for HCV have a high treatment success rate and can significantly reduce the risks of short and long-term complications of HCV infection. However, despite the evidence of the association between diabetes and HCV and the benefits of anti-HCV treatment, previously published guidelines did not focus on the universal HCV screening for patients with diabetes and their subsequent management once confirmed as having HCV viremia. Nonetheless, screening for HCV among patients with diabetes will contribute to the eradication of HCV infection. Thus, the three major Taiwan medical associations of diabetes and liver diseases endorsed a total of 14 experts in the fields of gastroenterology, hepatology, diabetology, and epidemiology to convene and formulate a consensus statement on HCV screening and management among patients with diabetes. Based on recent studies and guidelines as well as from real-world clinical experiences, the Taiwan experts reached a consensus that provides a straightforward approach to HCV screening, treatment, and monitoring of patients with diabetes.

A strategy to prevent hepatitis B virus (HBV) virologic reactivation (HBVr) and clinical reactivation (CR) during direct acting antiviral (DAA) treatment of hepatitis C virus (HCV)/HBV dual infection remains an unresolved issue. Noncirrhotic patients with dual HCV/HBV infection were enrolled and allocated randomly to 1 of 3 groups as follows: 12 weeks of DAA alone (group 1), 12 weeks of DAA plus 12 weeks of entecavir (group 2), or 12 weeks of DAA plus 24 weeks of entecavir (group 3). The entire study duration was 72 weeks. The primary end point was the occurrence of HBVr (defined by an increase of HBV DNA level >10-fold with quantifiable HBV DNA at baseline or the presence of HBV DNA with prior unquantifiable HBV DNA) and CR (defined by serum alanine aminotransferase level >2-fold the upper limit of normal in addition to HBVr). Fifty-six patients were allocated randomly as follows: 20 patients in group 1, 16 patients in group 2, and 20 patients in group 3. In group 1, HBV DNA levels increased significantly as early as 4 weeks after initiation of DAA and persisted until the end of the study. During DAA treatment, HBVr occurred in 50% in group 1 vs 0% in group 2 and 0% in group 3 (P <.001), whereas the majority of HBVr in groups 2 and 3 occurred 12 weeks after cessation of entecavir (cumulative incidence, 93.8% in group 2 and 94.7% in group 3). Three patients (5.4%; 1 in each group) showed CR at week 48 and did not receive entecavir treatment. Twelve weeks of entecavir is suggested to be co-administered with DAA for HCV/HBV dually infected patients. ClinicalTrials.gov no: NCT04405011. [ABSTRACT FROM AUTHOR]

Background: Hepatitis C virus (HCV) genotype 6 mainly distributes in Southeast Asia and South China. Because of the low prevalence in developed countries, optimal treatment for HCV genotype 6 in real-world setting remains to be determined. We aimed to evaluate the effectiveness and safety of sofosbuvir/velpatasvir (SOF/VEL) and glecaprevir/pibrentasvir (GLE/PIB) for patients with HCV genotype 6 infection in Taiwan.Methods: A total of 286 patients with chronic hepatitis C (CHC) genotype 6, 161 receiving 12-week SOF/VEL and 125 receiving 8-week GLE/PIB, were enrolled. All patients were followed up for 12 weeks after treatment completion. Demographic information, HCV viral load (VL), profiles of lipid and sugar, and adverse events were recorded and reviewed.Results: Sustained virological response (SVR) rates of SOF/VEL and GLE/PIB evaluated by intention-to-treat analysis were 99.38% and 100%, respectively. SVR achieved 100%, regardless of cirrhosis or viral load (cutoff: 6 MIU/mL), of both regimens by per-protocol analysis. Skin itching was the most common adverse event, with an overall incidence of 6.64% which was more prevalent in GLE/PIB (12.0%) than SOF/VEL (2.48%). A significant decrease in the estimated glomerular filtration rate was observed in patients receiving SOF/VEL but not in those receiving GLE/PIB at the time of SVR. No patient discontinued treatment due to adverse event.Conclusion: The high SVR and excellent safety of SOF/VEL and GLE/PIB in real-world setting reveals that the two DAA regimens are favorable options for treatment of HCV genotype 6 in Taiwan and Asia.

Background/purpose: The Taiwan Association for the Study of the Liver (TASL) HCV Registry (TACR) is a nationwide registry of chronic hepatitis C patients in Taiwan. This study evaluated antiviral effectiveness of ledipasvir (LDV)/sofosbuvir (SOF) in patients in the TACR.Methods: Patients enrolled in TACR from 2017-2020 treated with LDV/SOF were eligible. The primary outcome was the proportion of patients with sustained virologic response 12 weeks after end of treatment (SVR12).Results: 5644 LDV/SOF ± ribavirin-treated patients were included (mean age: 61.4 years; 54.4% female). Dominant viral genotypes were GT1 (50.8%) and GT2 (39.3%). 1529 (27.1%) patients had liver cirrhosis, including 201 (3.6%) with liver decompensation; 686 (12.2%) had chronic kidney disease. SVR12 was achieved in 98.6% of the overall population and in 98.2% and 98.7% of patients with and without cirrhosis, respectively. SVR12 rates in patients with compensated cirrhosis treated with LDV/SOF without RBV were >98%, regardless of prior treatment experience. SVR12 was 98.6%, 98.4%, 100%, 100%, and 98.7% among those with GT1, GT2, GT4, GT5, and GT6 infections, respectively. Although patient numbers were relatively small, SVR12 rates of 100% were reported in patients infected with HCV GT2, GT5, and GT6 with decompensated cirrhosis and 98% in patients with severely compromised renal function. LDV/SOF adherence ≤60% (P < 0.001) was the most important factor associated with treatment failure. Incidence of adverse events was 15.8%, with fatigue being the most common.Conclusion: LDV/SOF is effective and well tolerated in routine clinical practice in Taiwan. Cure rates were high across patient populations. [ABSTRACT FROM AUTHOR]

Background/purpose: Direct-acting antiviral agents (DAAs) have revolutionized the paradigm for HCV treatment. However, patients with HBV and HCV co-infection receiving DAAs are at significant risk of HBV reactivation, with limited literature addressing the roles of serum chemokines/chemokines. We aimed to explore the profiles and predictive value of serum cytokines/chemokines regarding HBV reactivation in this clinical setting.Methods: From 2017 to 2019, 25 patients with HBV and HCV co-infection scheduled for DAA therapy were prospectively enrolled. At enrolment and after DAA treatment, serial serum cytokine/chemokine levels were examined. The baseline and dynamic levels were compared between those with versus without HBV virologic (defined by an increase of serum HBV DNA to >10 times) and clinical reactivation (defined by > 1.5-fold elevated ALT level than nadir and >100 U/L; or > 2-fold increase from nadir and greater than the upper normal limit, in addition to virologic reactivation).Results: There were 20 patients (80%) experiencing HBV virologic reactivation and 6 patients (24%) experiencing clinical reactivation. Patients with clinical reactivation had higher pre-treatment TNF-alpha (27.93 versus 18.85 pg/mL, P = 0.015), lower week-4 IFN-gamma (1.07 versus 8.74 pg/mL, P = 0.020) levels and significant declines of CCL2 and TNF-alpha (P < 0.05). Single or combination of these cytokines helped predict clinical reactivation (all P < 0.05).Conclusion: Higher serum TNF-alpha at baseline and lower IFN-gamma at week 4 were associated with mild clinical reactivation of HBV in patients with HBV/HCV co-infection receiving DAAs. Combination of these cytokines reliably predicted HBV reactivation early. [ABSTRACT FROM AUTHOR]

Background/purpose: Genotype 2 (GT2) hepatitis C virus infection is the second common genotype in Taiwan. Real-world experience of ledipasvir/sofosbuvir (LDV/SOF) for GT2 infection is limited. The aim of this study is to evaluate the effectiveness and safety of LDV/SOF in patients with GT2 chronic hepatitis C (CHC) infection.Methods: CHC patients with GT2 infection receiving 12 weeks LDV/SOF from three hospitals were enrolled. HCV RNA was checked at baseline, end-of-treatment and 12 weeks after completing treatment. Demographic data, adverse events, renal function and metabolic profiles were recorded.Results: Among 392 enrolled patients, 33 patients (8.4%) were cirrhotic. Sustained virological response (SVR) rate was 96.7% (379/392) by intention-to-treat analysis and 97.2% (379/390) by per-protocol analysis. The SVR rate was lower in cirrhotic patients than in non-cirrhotic patients (90.6% vs 97.8%, p = 0.053). Two cirrhotic patients who took LDV/SOF plus ribavirin both achieved SVR. Neither drug-related severe adverse events nor discontinuation due to drug-related adverse event were reported. The estimated glomerular filtration rate (eGFR) remained stable in patients with chronic kidney disease 3a/3b.Conclusion: Twelve weeks of LDV/SOF treatment provided an excellent and safe regimen for GT2 CHC infection, particularly in non-cirrhotic patients.

Background/purpose: The assessment of drug-drug interaction (DDI) is important not only for safety but also for maintaining the efficacy of direct acting antivirals in chronic hepatitis C (CHC). This study aims to evaluate DDI before and during elbasvir/grazoprevir (EBR/GZR) treatment.Methods: CHC patients who treated with EBR/GZR in five hospitals were enrolled. The patients' demographic data, comorbidities, concomitant medications taken before and during EBR/GZR were recorded. DDI was evaluated using a tool from the HEP Drug Interactions (www.hep-druginteractions.org) website. In addition to the evaluation of DDI for EBR/GZR, the virtual DDI of ledipasvir/sofosbuvir (LDV/SOF), sofosbuvir/velpatasvir (SOF/VEL) and glecaprevir/pibrentasvir (GLE/PIB) were evaluated. Degrees of DDI were classified as "do not co-administer", "potential interaction", and "potentially weak interaction".Results: A total of 460 patients were enrolled. At baseline, 80.1% of patients had one or more comorbidities and 72.8% took one or more medications. Cardiovascular diseases (43.9%), gastrointestinal diseases (37.4%), and metabolic diseases (36.7%) were the three most common comorbidities. The prevalence of DDI before EBR/GZR treatment was 12.8% (59 patients). Among the same population, the prevalence of virtual DDI of SOF/VEL, GLE/PIB, and LDV/SOF were 38.5% (179 patients), 48.8% (220 patients), and 57.0% (262 patients), respectively. During EBR/GZR treatment, 167 patients (36.3%) took newly prescribed medications. One patient (0.2%) and seven patients (1/5%) exhibited do-not-co-administer and potential interaction with EBR/GZR, respectively.Conclusion: DDI was limited in treatment with EBR/GZR. DDI can occur upon the administering of a new medication during antiviral treatment and attention should be paid to it.Trial Registration Number: NCT03706222. [ABSTRACT FROM AUTHOR]

Background/purpose: While direct-acting antiviral regimens have been approved for chronic hepatitis C (CHC) patients in Taiwan, reimbursement is limited to certain populations. Thus, pegylated interferon plus ribavirin (PEG-IFN/RBV) remains the standard of care for many patients. The aim of this study was to investigate the percentage of CHC patients who were recommended and willing to receive PEG-IFN/RBV, and to identify reasons why patients were not recommended or unwilling to receive treatment.Methods: 822 Taiwanese CHC patients were enrolled from May-August 2016 in this cross-sectional study. PEG-IFN/RBV recommendation and patient willingness to receive treatment were evaluated through surveys. Patient characteristics associated with treatment recommendation and willingness were assessed.Results: 311 (37.8%) patients were recommended PEG-IFN/RBV while 102 (12.4%) were willing to follow treatment recommendation. Rates of recommendation and willingness were lower in treatment-experienced, hepatitis C virus genotype 1 (GT1) and cirrhotic patients, and those treated in Northern Taiwan. Multivariate analyses found factors such as prior treatment experience, GT1, cirrhosis and low hemoglobin levels to be associated with lower recommendation rates while advanced age, GT1 and low baseline viral loads were associated with lower willingness rates. Physicians' top reasons for not recommending PEG-IFN/RBV included the wish to wait for better treatment options (60.3%), prior treatment failure (21.3%) and patients' advanced age (20.9%). Patients were unwilling to receive treatment mainly due to concerns about side effects (91.4%), the wish to wait for better treatment options (71.3%) and inconvenience (25.4%).Conclusion: A minority of Taiwanese CHC patients were recommended PEG-IFN/RBV, of which few were willing to receive treatment.

Background and Purpose: Sofosbuvir (SOF) and daclatasvir (DCV) treatment achieves excellent efficacy and safety in treating chronic hepatitis C (CHC) with various genotypes. Real world experience of SOF/DCV regimen to treat genotype 2 CHC was scanty in Asia. This study aimed to evaluate the effectiveness and safety of SOF/DCV with or without ribavirin to treat genotype 2 CHC patients in real world practice in Taiwan.Methods: Patients with genotype 2 CHC treated with 12-week of SOF/DCV or SOF/DCV/ribavirin were enrolled prospectively. Effectiveness was evaluated by sustained virological response (SVR) which was defined as undetectable hepatitis C virus (HCV) RNA at post-treatment week 12. Adverse events were recorded for safety analysis.Results: In total of 32 patients were enrolled from October 2016 to June 2017. All were infected with genotype 2 HCV. Sixteen patients (50%) exhibited cirrhosis including 6 patients with decompensation. Regimens of SOF/DCV and SOF/DCV/ribavirin were used to treat 14 and 18 patients, respectively. SVR was achieved in all 31 patients (100%) who completed follow-up. Significantly higher levels of cholesterol (p = 0.013) and higher low density lipoprotein-cholesterol (p = 0.015) were exhibited after successful viral clearance. SOF/DCV/ribavirin regimen resulted in more adverse events, significantly higher bilirubin levels, and decline of hemoglobin during treatment than SOF/DCV regimen. Four patients with chronic kidney disease maintained renal function during treatment. Overall, SOF/DCV or SOF/DCV/ribavirin treatment was well tolerated.Conclusion: SOF/DCV with or without ribavirin is highly effective and safe for patients with genotype 2 HCV infection in real-world experience in Taiwan.

Background/purpose: Treatment with daclatasvir plus asunaprevir (DCV + ASV) for 24 weeks provided a sustained virologic response (SVR) rate of over 90% in hepatitis C virus genotype 1b (HCV-1b) infected patients without non-structural 5A (NS5A) resistance-associated substitutions (RASs) at the L31 and Y93 sites. In this study, we investigated whether adding ribavirin to the DCV + ASV combination could shorten the original treatment regimen to 12 weeks without compromising the treatment efficacy for HCV-1b patients without NS5A RASs.Methods: In the prospective, open-label, single-arm, nationwide multi-center phase III study, a total of 70 interferon-naïve or interferon-experienced HCV-1b patients without baseline L31/Y93 RASs received daclatasvir (60 mg/day) and asunaprevir (100 mg twice daily) plus weight-based ribavirin (1000-1200 mg/day) for 12 weeks, with a 12-week post-treatment follow-up. The primary end-point was the rate of undetectable HCV RNA 12 weeks post-treatment (SVR12).Results: The SVR12 rate was 97.1% (68/70) and 100% (68/68) in the full-analysis-set and the per-protocol population, respectively. None of the 68 patients who completed the 12-week treatment experienced relapse during post-treatment follow-up. Two patients withdrew from the study at treatment days 21 and 34 due to anorexia and fatigue, which were considered ribavirin-related and resolved post medication cessation. A total of 4 serious adverse events were reported and considered treatment-unrelated. No deaths or grade 4 adverse events requiring hospitalization was observed throughout the study.Conclusion: Truncated regimen of DCV + ASV plus ribavirin for 12 weeks was highly effective and safe in HCV-1b patients without NS5A L31/Y93 RAS.

The effect of race on routinely available noninvasive tests of fibrosis is incompletely understood. This study evaluated the performance of noninvasive tests among white and Asian patients in the STELLAR trials (NCT03053050 and NCT03053063), which evaluated selonsertib in patients with advanced (F3-F4) fibrosis due to nonalcoholic steatohepatitis (NASH). Baseline liver biopsies were centrally read using the NASH Clinical Research Network system, and 4 noninvasive tests (Nonalcoholic fatty liver disease fibrosis score [NFS], Fibrosis-4 index [FIB-4], Enhanced Liver Fibrosis test [ELF], and liver stiffness by vibration-controlled transient elastography) were measured. The performance of these tests to discriminate advanced fibrosis was evaluated using areas under the receiver operating characteristics curves with 5-fold cross-validation repeated 100 times. Among 3207 patients screened with evaluable liver histology, 2281 were whites and 762 were Asians. Seventy-two percent of whites and 67% of Asians had advanced fibrosis. The areas under the receiver operating characteristics curves of the noninvasive tests for advanced fibrosis were similar in whites and Asians: 0.73 and 0.75 for NFS, 0.78 and 0.80 for FIB-4, 0.79 and 0.81 for ELF, and 0.80 and 0.83 for liver stiffness, respectively. At the published cutoffs, the tests had similar sensitivities and specificities in the 2 groups. However, the sensitivities of NFS, FIB-4, and ELF were low in both white and Asian patients younger than 40 years. In the global phase III STELLAR trials, the diagnostic performance of routinely available noninvasive tests for the detection of advanced fibrosis due to NASH was acceptable and similar between white and Asian patients.

Sofosbuvir is approved for chronic hepatitis C (CHC) patients with severe chronic kidney disease (CKD). The impact of sofosbuvir-based therapy on renal function augmentation on a real-world nationwide basis is elusive. The 12,995 CHC patients treated with sofosbuvir-based (n = 6802) or non–sofosbuvir-based (n = 6193) regimens were retrieved from the Taiwan nationwide real-world HCV Registry Program. Serial estimated glomerular filtration rate (eGFR) levels were measured at baseline, end of treatment (EOT), and end of follow-up (EOF) (3 months after EOT). The eGFR decreased from baseline (91.4 mL/min/1.73 m2) to EOT (88.4 mL/min/1.73 m2; P <.001) and substantially recovered at EOF (88.8 mL/min/1.73 m2) but did not return to pretreatment levels (P <.001). Notably, a significant decrease in eGFR was observed only in patients with baseline eGFR ≥90 mL/min/1.73 m2 (from 112.9 to 106.4 mL/min/1.73 m2; P <.001). In contrast, eGFR increased progressively in patients whose baseline eGFR was <90 mL/min/1.73 m2 (from 70.0 to 71.5 mL/min/1.73 m2; P <.001), and this increase was generalized across different stages of CKD. The trend of eGFR amelioration was consistent irrespective of sofosbuvir usage. Multivariate adjusted analysis demonstrated that baseline eGFR >90 mL/min/1.73 m2 was the only factor independently associated with significant slope coefficient differences of eGFR (–1.98 mL/min/1.73 m2; 95% confidence interval, –2.24 to –1.72; P <.001). The use of sofosbuvir was not an independent factor associated with eGFR change. Both sofosbuvir and non–sofosbuvir-based regimens restored renal function in CHC patients with CKD, especially in those with significant renal function impairment. [ABSTRACT FROM AUTHOR]

Background/purpose: Aeromonas infections, rarely reported in Western countries, are not uncommon infectious diseases in Taiwan. The clinical manifestations and prognostic factors of Aeromonas spontaneous bacterial peritonitis (SBP) in patients with liver cirrhosis were investigated.Methods: We reviewed the medical charts and microbiological records of liver cirrhosis patients with Aeromonas SBP between January 1990 and December 2005, in a medical center in southern Taiwan.Results: Thirty-one liver cirrhosis patients developed Aeromonas SBP within a 16-year period. The majority (26, 84%) had concurrent Aeromonas bacteremia. A. sobria (55%) and A. hydrophila (45%) were the causative species. The predominant clinical manifestations included fever (84%), abdominal pain (74%), hypotension on admission (48%), altered mental status (45%), and acute renal failure (42%). Gram-negative bacilli were found in Gram staining of ascitic fluids in 27% of 26 patients, while aeromonads were isolated from ascitic fluids in 55% of 31 patients. The yield rate of ascitic fluid cultures decreased greatly, if paracentesis was performed at > 3 hours after the administration of antimicrobial therapy. All but one patient received in-vitro-active antimicrobial agents within 48 hours, but the all-cause mortality rate was 56%. Initial high Pitt's bacteremia score was independently associated with a fatal outcome in multivariate analysis.Conclusion: Aeromonas SBP is a fatal disease, and must be included in the differential diagnosis of SBP in patients with advanced liver cirrhosis in endemic areas.

Background & Aims Transient elastography (TE) is a noninvasive technique used to measure liver stiffness to estimate the severity of fibrosis. The range of liver stiffness measurements (LSMs) in healthy individuals is unclear. We performed a systematic review to determine the range of LSMs, examined by TE, in healthy individuals and individuals who are susceptible to fibrosis. Methods We collected data from 16,082 individuals, in 26 cohorts, identified from systematic searches of Embase, Ovid MEDLINE, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews for studies of liver stiffness measurements. Studies analyzed included apparently healthy adults (normal levels of liver enzymes, low-risk alcohol use patterns, and negative for markers of viral hepatitis). The presence of diabetes, hypertension, dyslipidemia, or steatosis, based on ultrasound examination, was known for most participants. We performed a meta-analysis of data from individual participants. The cohort was divided into 4 groups; participants with a body mass index <30 kg/m2 were examined with the medium probe and those with a body mass index ≥30 kg/m2 were examined with the extra-large probe. Linear regression models were conducted after adjusting for potential confounding factors of LSMs. We performed several sensitivity analyses. Results We established LSM ranges for healthy individuals measured with both probes—these did not change significantly in sensitivity analyses of individuals with platelets ≥150,000/mm3 and levels of alanine aminotransferase ≤33 IU/L in men or ≤25 IU/L in women. In multivariate analysis, factors that modified LSMs with statistical significance included diabetes, dyslipidemia, waist circumference, level of aspartate aminotransferase, and systolic blood pressure at examination time. Significant increases in LSMs were associated with the metabolic syndrome in individuals examined by either probe. Diabetes in obese individuals increased the risk of LSMs in the range associated with advanced fibrosis. Conclusions In a systematic review and meta-analysis of data from individual participants, we established a comprehensive set of LSM ranges, measured by TE in large cohorts of healthy individuals and persons susceptible to hepatic fibrosis. Regression analyses identified factors associated with increased LSMs obtained by TE with the medium and extra-large probes. [ABSTRACT FROM AUTHOR]
