RESUMEN
BACKGROUND/AIMS: Hepatitis C virus (HCV) eradication using antiviral agents augments the metabolic profile. Changes in glycated hemoglobin (HbA1c) levels in chronic hepatitis C patients who receive glecaprevir/pibrentasvir (GLE/PIB) remain elusive. METHODS: Data from 2417 patients treated with GLE/PIB from the Taiwan HCV Registry were analyzed, and pretreatment HbA1c levels were compared with 3-months after the-end-of treatment levels. A sustained virological response (SVR) was defined as undetectable HCV RNA at 12 weeks after the end of treatment. A significant change in HbA1c level was defined as the 75th percentile of the change in the HbA1c level before and after treatment (decrement >0.2%). RESULTS: Serum HbA1c levels decreased significantly (6.0 vs 5.9%, P < 0.001). Post-treatment HbA1c levels decreased in all subgroups, except in non-SVR patients (5.7 vs 5.7%, P = 0.79). Compared to patients without significant HbA1c improvement (decrement >0.2%), those with HbA1c improvement were older (60.2 vs 58.6 years, P < 0.001), had higher serum creatinine levels (1.9 vs 1.6 mg/dL, P < 0.001), triglycerides (129.8 vs 106.2 mg/dL, P < 0.001), fasting glucose (135.8 vs 104.0 mg/dL, P < 0.001), and pretreatment HbA1c (7.1 vs 5.7%, P < 0.001) and had a higher proportion of male sex (57.9% vs 50.9%, P = 0.003), diabetes (84.3 vs 16.8%, P < 0.001), more advanced stages of chronic kidney disease (CKD) (15.7 vs 11.1 %, P < 0.001), anti-diabetic medication use (47.3 vs 16.4%, P < 0.001) and fatty liver (49.6 vs 38.3 %, P < 0.001). Multivariate analysis revealed that the factors associated with significant HbA1c improvement were age (odds ratio [OR]/95% confidence intervals [CI]: 1.01/1.00-1.02, P = 0.01), HbA1c level (OR/CI: 2.83/2.48-3.24, P < 0.001) and advanced CKD stages (OR/CI: 1.16/1.05-1.28, P = 0.004). If the HbA1c variable was not considered, the factors associated with significant HbA1c improvement included alanine aminotransferase level (OR/CI, 1.002/1.000-1.004, P = 0.01), fasting glucose level (OR/CI: 1.010/1.006-1.013, P < 0.001), and diabetes (OR/CI: 3.35/2.52-4.45, P < 0.001). CONCLUSIONS: The HbA1c levels improved shortly after HCV eradication using GLE/PIB. The improvement in glycemic control can be generalized to all subpopulations, particularly in patients with a higher baseline HbA1c level or diabetes.
RESUMEN
BACKGROUND: Chronic hepatitis C (CHC) increases the risk of liver cirrhosis (LC) and hepatocellular carcinoma (HCC). This nationwide cohort study assessed the effectiveness of viral eradication of CHC. METHODS: The Taiwanese chronic hepatitis C cohort and Taiwan hepatitis C virus (HCV) registry are nationwide HCV registry cohorts incorporating data from 23 and 53 hospitals in Taiwan, respectively. This study included 27,577 individuals from these cohorts that were given a diagnosis of CHC and with data linked to the Taiwan National Health Insurance Research Database. Patients received either pegylated interferon and ribavirin or direct-acting antiviral agent therapy for > 4 weeks for new-onset LC and liver-related events. RESULTS: Among the 27,577 analyzed patients, 25,461 (92.3%) achieved sustained virologic response (SVR). The mean follow-up duration was 51.2 ± 48.4 months, totaling 118,567 person-years. In the multivariable Cox proportional hazard analysis, the hazard ratio (HR) for incident HCC was 1.39 (95% confidence interval [CI]: 1.00-1.95, p = 0.052) among noncirrhotic patients without SVR compared with those with SVR and 1.82 (95% CI 1.34-2.48) among cirrhotic patients without SVR. The HR for liver-related events, including HCC and decompensated LC, was 1.70 (95% CI 1.30-2.24) among cirrhotic patients without SVR. Patients with SVR had a lower 10-year cumulative incidence of new-onset HCC than those without SVR did (21.7 vs. 38.7% in patients with LC, p < 0.001; 6.0 vs. 18.4% in patients without LC, p < 0.001). CONCLUSION: HCV eradication reduced the incidence of HCC in patients with and without LC and reduced the incidence of liver-related events in patients with LC.
RESUMEN
INTRODUCTION: Eight-week glecaprevir/pibrentasvir (GLE/PIB) is indicated for treatment-naïve (TN) patients with chronic hepatitis C (CHC), with or without compensated cirrhosis. Given that the Taiwanese government is committed to eliminating hepatitis C virus (HCV) by 2025, this study aimed to measure real-world evidence for TN patients using 8-week GLE/PIB in the Taiwan HCV Registry (TACR). METHODS: The data of patients with CHC treated with 8-week GLE/PIB were retrieved from TACR, a nationwide registry program organized by the Taiwan Association for the Study of the Liver (TASL). Treatment efficacy, defined as a sustained virologic response at posttreatment week 12 (SVR12), was assessed in the modified intention-to-treat (mITT) population, which excluded patients who were lost to follow-up or lacked SVR12 data. The safety profile of the ITT population was assessed. RESULTS: A total of 7246 (6897 without cirrhosis; 349 with cirrhosis) patients received at least one dose of GLE/PIB (ITT), 7204 of whom had SVR12 data available (mITT). The overall SVR12 rate was 98.9% (7122/7204) among all patients, 98.9% (6780/6856) and 98.3% (342/348) among patients without and with cirrhosis, respectively. For the selected subgroups, which included patients with genotype 3 infection, diabetes, chronic kidney disease, people who injected drugs, and those with human immunodeficiency virus coinfection, the SVR12 rates were 95.1% (272/286), 98.9% (1084/1096), 99.0% (1171/1183), 97.4% (566/581), and 96.1% (248/258), respectively. Overall, 14.1% (1021/7246) of the patients experienced adverse events (AEs). Twenty-two patients (0.3%) experienced serious AEs, and 15 events (0.2%) resulted in permanent drug discontinuation. Only one event was considered treatment drug related. CONCLUSION: Eight-week GLE/PIB therapy was effective and well tolerated in all TN patients, regardless of cirrhosis status.
RESUMEN
BACKGROUND: Large-scale real-world data of the 8-week glecaprevir/pibrentasvir (GLE/PIB) therapy for treatment-naïve patients of chronic hepatitis C virus (HCV) infection with compensated cirrhosis is scarce. METHODS: The TASL HCV Registry (TACR) is an ongoing nationwide registry program that aims to set up a database and biobank of patients with chronic HCV infection in Taiwan. In this study, data were analyzed as of 31 October 2021 for treatment-naïve HCV patients with compensated cirrhosis receiving 8-week GLE/PIB therapy. Effectiveness reported as sustained virologic response at off-therapy week 12 (SVR12) and safety profiles were assessed. Patient characteristics potentially related to SVR12 were also evaluated. RESULTS: Of the 301 patients enrolled, 275 had available SVR12 data. The SVR12 rate was 98.2% (270/275) in the modified intention-to-treat (mITT) population and 89.7% (270/301) in the ITT population. For those mITT patients with genotype 3, FibroScan > 20 kPa, platelet < 150,000/µl, and FibroScan > 20 kPa and platelet < 150,000/µl, the SVR12 rates were 100% (6/6), 100% (12/12), 98.0% (144/147), 100% (7/7), respectively. Overall, 24.9% (75/301) patients experienced adverse events (AEs). The most frequent AEs (> 5%) included fatigue (9.0%) and pruritus (7.0%). Seven (2.3%) patients experienced serious AEs and two (0.7%) resulted in permanent drug discontinuation. None of them were considered as GLE/PIB-related. CONCLUSIONS: In this large-scale real-world Taiwanese cohort, 8-week GLE/PIB therapy was efficacious and well tolerated for treatment-naïve compensated cirrhosis patients. SVR12 rates were similarly high as in the clinical trials, including those with characteristics of advanced liver disease.

BACKGROUND: Real-world data are scarce about the effectiveness and safety of sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) for retreating East Asian patients with hepatitis C virus (HCV) infection who previously received NS5A direct-acting antivirals (DAAs). We conducted a multicenter study to assess the performance of SOF/VEL/VOX in patients who were not responsive to prior NS5A inhibitors in Taiwan. METHODS: Between September 2021 and May 2022, 107 patients who failed NS5A inhibitor-containing DAAs with SOF/VEL/VOX salvage therapy for 12 weeks were included at 16 academic centers. The sustained virologic response at off-treatment week 12 (SVR12) was assessed in the evaluable (EP) and per-protocol (PP) populations. The safety profiles were also reported. RESULTS: All patients completed 12 weeks of treatment and achieved an end-of-treatment virologic response. The SVR12 rates were 97.2% (95% confidence interval (CI) 92.1-99.0%) and 100% (95% CI 96.4-100%) in EP and PP populations. Three (2.8%) patients were lost to off-treatment follow-up and did not meet SVR12 in the EP population. No baseline factors predicted SVR12. Two (1.9%) not-fatal serious adverse events (AE) occurred but were unrelated to SOF/VEL/VOX. Sixteen (15.0%) had grade 2 total bilirubin elevation, and three (2.8%) had grade 2 alanine transaminase (ALT) elevation. Thirteen (81.3%) of the 16 patients with grade 2 total bilirubin elevation had unconjugated hyperbilirubinemia. The estimated glomerular filtration rates (eGFR) were comparable between baseline and SVR12, regardless of baseline renal reserve. CONCLUSIONS: SOF/VEL/VOX is highly efficacious and well-tolerated for East Asian HCV patients previously treated with NS5A inhibitor-containing DAAs. CLINICAL TRIALS REGISTRATION: The study was not a drug trial. There was no need for clinical trial registration.

Aluminum has been extensively used as a conductor material in numerous electronic devices, including solar cells, light-emitting diodes (LEDs), organic LEDs (OLEDs), and thin-film transistors. However, its spiking surface and easy electromigration have limited its performance. To overcome this, a trace amount of nonprecious copper dopant has been proven effective in enhancing device reliability. Nevertheless, a comprehensive investigation regarding the effect of copper doping on the morphology at the aluminum conductor-organic interface is yet to be done. We had hence fabricated a series of green OLED devices to probe how copper doping affected the aluminum conductor, morphologically and electrically, and the corresponding device's efficiency and lifetime performance. We found 4 wt % copper doping to be highly effective in enabling a spike-less and smoother aluminum interface, which in turn enabled the fabrication of devices with much higher efficiency and lifetime. Specifically, the corresponding power efficacy at 1000 cd/m2 was increased from 32 to 42 lm/W and the lifetime increased from 75 to 263 h, an increment of 250%. Atomic force microscopy confirmed that the copper doping did help smooth out the conductor interface as deposited and reduce electromigration upon operation.
RESUMEN
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.

To clarify the predictive factors of significant platelet count improvement in thrombocytopenic chronic hepatitis C (CHC) patients. CHC patients with baseline platelet counts of <150 × 103/µL receiving direct-acting antiviral (DAA) therapy with at least 12-weeks post-treatment follow-up (PTW12) were enrolled. Significant platelet count improvement was defined as a ≥10% increase in platelet counts at PTW12 from baseline. Platelet count evolution at treatment week 4, end-of-treatment, PTW12, and PTW48 was evaluated. This study included 4922 patients. Sustained virologic response after 12 weeks post-treatment was achieved in 98.7% of patients. Platelet counts from baseline, treatment week 4, and end-of-treatment to PTW12 were 108.8 ± 30.2, 121.9 ± 41.1, 123.1 ± 43.0, and 121.1 ± 40.8 × 103/µL, respectively. Overall, 2230 patients (45.3%) showed significant platelet count improvement. Multivariable analysis revealed that age (odds ratio (OR) = 0.99, 95% confidence interval (CI): 0.99-1.00, p = 0.01), diabetes mellitus (DM) (OR = 1.20, 95% CI: 1.06-1.38, p = 0.007), cirrhosis (OR = 0.66, 95% CI: 0.58-0.75, p < 0.0001), baseline platelet counts (OR = 0.99, 95% CI: 0.98-0.99, p < 0.0001), and baseline total bilirubin level (OR = 0.80, 95% CI: 0.71-0.91, p = 0.0003) were independent predictive factors of significant platelet count improvement. Subgroup analyses showed that patients with significant platelet count improvement and sustained virologic responses, regardless of advanced fibrosis, had a significant increase in platelet counts from baseline to treatment week 4, end-of-treatment, PTW12, and PTW48. Young age, presence of DM, absence of cirrhosis, reduced baseline platelet counts, and reduced baseline total bilirubin levels were associated with significant platelet count improvement after DAA therapy in thrombocytopenic CHC patients.

INTRODUCTION: Pangenotypic direct-acting antivirals are expected to cure hepatitis C virus (HCV) in more than 95% of treated patients. However, data on the effectiveness and safety of sofosbuvir/velpatasvir (SOF/VEL) in Taiwan are limited. This study aims to characterize the patient population in the nationwide Taiwan Association for the Study of the Liver (TASL) HCV Registry and evaluate treatment outcome in Taiwanese patients receiving SOF/VEL. METHODS: This study was a retrospective-prospective, observational, multicenter, real-world analysis. Adults with chronic hepatitis C were treated with SOF/VEL 400/100 mg ± ribavirin for 12 weeks. The primary outcome was sustained virologic response 12 weeks after end of therapy (SVR12). Factors associated with not achieving SVR12 were evaluated using logistic regression and covariate analysis. Safety was also assessed. RESULTS: In total, 3480 patients were included: 86.8% genotype 1/2, 2.8% genotype 3, 0.1% genotype 4/5, 9.6% genotype 6; unclassified, 0.8%; 12.2% compensated cirrhosis; 3.3% decompensated cirrhosis; and 15.8% chronic kidney disease. Overall SVR12 rate was 99.4% (genotype 1, 99.5%; genotype 2, 99.4%; genotype 3, 96.9%; genotype 4, 100%; genotype 6, 99.7%). SVR12 rates among patients with compensated cirrhosis, decompensated cirrhosis, and chronic kidney disease stages 4-5 were 99.5%, 100%, and 100%, respectively. There were 21 patients (0.6%) who did not achieve SVR12. Factors associated with failure were treatment adherence below 60%, high viral load, and genotype 3 (p < 0.001, p = 0.028, and p = 0.001, respectively). Adverse events occurred in 10% of patients; 0.6% were serious and one was related to treatment. Treatment discontinuation occurred in 0.3% of patients; none were treatment related. The estimated glomerular filtration rate remained stable throughout treatment and follow-up, regardless of baseline values and cirrhosis status. CONCLUSION: SOF/VEL was highly effective and well tolerated in Taiwanese patients, irrespective of viral genotype, liver disease severity, and comorbidities.
RESUMEN
BACKGROUND & AIMS: 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. METHODS: 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). RESULTS: 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. CONCLUSIONS: Both sofosbuvir and non-sofosbuvir-based regimens restored renal function in CHC patients with CKD, especially in those with significant renal function impairment.

OBJECTIVE: Data regarding the real-world effectiveness and safety of sofosbuvir/velpatasvir (SOF/VEL) with or without low-dose ribavirin (RBV) in patients with chronic hepatitis C virus (HCV) infection and severe renal impairment (RI) are limited. We evaluated the performance of SOF/VEL with or without low-dose RBV in HCV-infected patients with chronic kidney disease stage 4 or 5. DESIGN: 191 patients with compensated (n=181) and decompensated (n=10) liver diseases receiving SOF/VEL (400/100 mg/day) alone and SOF/VEL with low-dose RBV (200 mg/day) for 12 weeks were retrospectively recruited at 15 academic centres in Taiwan. The effectiveness was determined by sustained virological response at off-treatment week 12 (SVR12) in evaluable (EP) and per-protocol populations (PP). The safety profiles were assessed. RESULTS: The SVR12 rates by EP and PP analyses were 94.8% (95% CI 90.6% to 97.1%) and 100% (95% CI 97.9% to 100%). In patients with compensated liver disease, the SVR12 rates were 95.0% and 100% by EP and PP analyses. In patients with decompensated liver disease, the SVR12 rates were 90.0% and 100% by EP and PP analyses. Ten patients who failed to achieve SVR12 were attributed to non-virological failures. Among the 20 serious adverse events (AEs), none were judged related to SOF/VEL or RBV. The AEs occurring in ≥10% included fatigue (14.7%), headache (14.1%), nausea (12.6%), insomnia (12.0%) and pruritus (10.5%). None had ≥grade 3 total bilirubin or alanine aminotransferase elevations. CONCLUSION: SOF/VEL with or without low-dose RBV is effective and well-tolerated in HCV-infected patients with severe RI.

The study evaluated the real-world treatment outcomes of Glecaprevir/pibrentasvir (GLE/PIB) including effectiveness, safety and healthcare resource utilization based on a nation-wide registry in Taiwan. The Taiwan HCV Registry (TACR) is a nation-wide platform organized and supervised by the Taiwan Association for the Study of the Liver. Data were analyzed for patients treated with GLE/PIB, including 3144 patients who had treatment outcome available. The primary endpoint was sustained virological response (SVR12, undetectable HCV RNA throughout 12 weeks of end-of-treatment). The overall SVR12 rate was 98.9% (3110/3144), with 98.8%, 99.4% and 100% in patients receiving 8 weeks, 12 weeks, and 16 weeks of GLE/PIB respectively. The SVR12 rate in the treatment-naïve cirrhotic patients receiving 8 weeks of GLE/PIB was 98.2% (108/110). The most common AEs were fatigue (7.5%), pruritus (6.7%) and dizziness (1.5%). The mean number of outpatient visits during the GLE/PIB was 5.94 visits for patients treated with 8 weeks, significantly different from the patients treated with 12 weeks of GLE/PIB (6.90 visits). The results support the effectiveness and safety of GLE/PIB treatment in real-world clinical practice, and provide further evidence that the shorter, 8-week GLE/PIB regimen is effective and cost-saving.

BACKGROUND/AIMS: Real-world studies assessing the effectiveness and safety of sofosbuvir/velpatasvir (SOF/VEL) plus ribavirin (RBV) for Child-Pugh B/C hepatitis C virus (HCV)-related cirrhosis are limited. METHODS: We included 107 patients with Child-Pugh B/C HCV-related cirrhosis receiving SOF/VEL plus RBV for 12 weeks in Taiwan. The sustained virologic response rates at off-treatment week 12 (SVR12) for the evaluable population (EP), modified EP, and per-protocol population (PP) were assessed. Thesafety profiles were reported. RESULTS: The SVR12 rates in the EP, modified EP and PP were 89.7% (95% confidence interval [CI], 82.5-94.2%), 94.1% (95% CI, 87.8-97.3%), and 100% (95% CI, 96.2-100%). Number of patients who failed to achieve SVR12 were attributed to virologic failures. The SVR12 rates were comparable regardless of patient characteristics. One patient discontinued treatment because of adverse events (AEs). Twenty-four patients had serious AEs and six died, but none were related to SOF/VEL or RBV. Among the 96 patients achieving SVR12, 84.4% and 64.6% had improved Child-Pugh and model for endstage liver disease (MELD) scores. Multivariate analysis revealed that a baseline MELD score ≥15 was associated with an improved MELD score of ≥3 (odds ratio, 4.13; 95% CI, 1.16-14.71; P=0.02). Patients with chronic kidney disease (CKD) stage 1 had more significant estimated glomerular filtration rate declines than patients with CKD stage 2 (-0.42 mL/min/1.73 m2/month; P=0.01) or stage 3 (-0.56 mL/min/1.73 m2/month; P<0.001). CONCLUSION: SOF/VEL plus RBV for 12 weeks is efficacious and well-tolerated for Child-Pugh B/C HCV-related cirrhosis.

BACKGROUND: Data regarding the real-world effectiveness and safety of sofosbuvir/velpatasvir (SOF/VEL) for East Asian patients with chronic hepatitis C virus (HCV) infection and compensated liver disease are limited. We evaluated the performance of SOF/VEL for 12 weeks for HCV-infected patients with compensated liver disease in a large real-world cohort in Taiwan. METHODS: Between July 2019 and March 2020, 1880 HCV-infected patients with compensated liver disease who received SOF/VEL 400/100 mg once daily for 12 weeks were included at 15 academic centers in Taiwan. The sustained virologic response at off-treatment week 12 (SVR12) was assessed for evaluable (EP) and per-protocol populations (PP). The tolerance was also reported. RESULTS: The SVR12 rates by EP and PP analyses were 95.6% [1798 of 1880 patients; 95% confidence interval (CI) 94.6-96.5%] and 99.3% (1798 of 1811 patients; 95% CI 98.8-99.6%), respectively. Among 82 patients who failed to achieve SVR12, 13 (15.9%) were attributed to virologic failures. The SVR12 rates were comparable regardless of baseline characteristics. A total of 1859 (98.9%) patients completed 12-week SOF/VEL treatment. Four (0.2%) patients discontinued treatment due to adverse events (AEs). All patients with serious AEs or deaths were judged not related to SOF/VEL. The AEs occurring in ≥ 10% included headache (16.8%), fatigue (16.2%), nausea (11.8%), and insomnia (11.1%). Nine (0.5%) and 2 (0.1%) patients had grade 3 total bilirubin and alanine aminotransferase elevations. CONCLUSIONS: SOF/VEL for 12 weeks is efficacious and well-tolerated by chronic HCV-infected patients with compensated liver disease in Taiwan.

BACKGROUND/AIMS: Direct-acting antivirals (DAAs) are highly effective in treating chronic hepatitis C virus (HCV)-infected patients. The real-world treatment outcome in Taiwanese patients on a nationwide basis is elusive. METHODS: The Taiwan HCV Registry (TACR) programme is a nationwide registry platform including 48 study sites, which is organized and supervised by the Taiwan Association for the Study of the Liver. The primary endpoint was sustained virological response (SVR12, undetectable HCV RNA 12 weeks after end-of-treatment). RESULTS: A total of 13 951 registered patients with SVR12 data available were analysed (mean age, 63.0 years; female, 55.9%; HCV genotype-1 [GT1], 57.9%; cirrhosis, 38.4%; preexisting hepatocellular carcinoma [HCC], 10.6%; and hepatitis B virus coinfection, 7.7%). The overall SVR12 rate was 98.3%, with 98.7%, 98.0%, 98.4% and 97.4% in treatment-naïve noncirrhotic, treatment-naïve cirrhotic, treatment-experienced noncirrhotic and treatment-experienced cirrhotic patients, respectively. The SVR12 rate was > 95% across all subgroups except treatment-experienced cirrhotic patients who received sofosbuvir/ribavirin (88.7%), treatment-naïve noncirrhotic patients (94.8%) and treatment-experienced cirrhotic (94.8%) patients who received daclatasvir/asunaprevir. The most important factor associated with treatment failure was DAA adherence < 60% ( adjusted odds ratio [aOR]/95% confidence interval [CI]: 117.1/52.4-261.3, P < .001), followed by GT3/GT2 (aOR/CI: 5.78/2.25-14.9, P = .0003 and aOR/CI: 1.55/1.05-2.29, P = .03, compared with GT1), active hepatocellular carcinoma (aOR/CI: 4.29/2.57-7.16, P < .001), the use of sofosbuvir/ribavirin (aOR/CI: 2.51/1.67-3.77, P < .001) and daclatasvir/asunaprevir (aOR/CI: 3.29/1.94-5.58, P < .001), decompensated liver cirrhosis (aOR/CI: 2.50/1.20-5.22, P = .02) and high HCV viral loads (aOR/CI: 2.16/1.57-2.97, P < .001). CONCLUSIONS: DAAs are highly effective in treating Taiwanese HCV patients in the real-world setting. Maintaining DAA adherence and selecting highly efficacious regimens are keys to ensure treatment success.
