Real-world anti-viral treatment decisions among chronic hepatitis C patients in Taiwan: The INITIATE study. J Formos Med Assoc 2018; 118:1014-1023. [PMID: 30448077 DOI: 10.1016/j.jfma.2018.10.020] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2018] [Revised: 08/27/2018] [Accepted: 10/30/2018] [Indexed: 02/07/2023] Open
Abstract
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.

A noninvasive diagnosis of hepatic fibrosis by BioFibroScore® in chronic hepatitis C patients. J Gastroenterol Hepatol 2018; 33:291-297. [PMID: 28548299 DOI: 10.1111/jgh.13834] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2017] [Revised: 05/09/2017] [Accepted: 05/13/2017] [Indexed: 01/18/2023]
Abstract
BACKGROUND AND AIMS The diagnostic accuracy of a novel serological panel (BioFibroScore®) to predict hepatic fibrosis in patients with chronic hepatitis C virus (HCV) infection is unknown. METHODS Three markers of BioFibroScore, including urokinase plasminogen activator, matrix metalloproteinase-9, and beta-2 microglobulin, were retrospectively evaluated in 635 HCV-infected patients who received percutaneous liver biopsy and FibroScan®. The formula of BioFibroScore to predict the severity of hepatic fibrosis was developed by adaptive boosting algorithm. The diagnostic accuracy of hepatic fibrosis was assessed both for BioFibroScore and FibroScan, taking METAVIR fibrosis score as the reference standard. RESULTS Urokinase plasminogen activator and beta-2 microglobulin were positively and matrix metalloproteinase-9 was negatively associated with the severity of hepatic fibrosis. Thirty-five (5.5%) patients had failed FibroScan assessment. By adaptive boosting model for BioFibroScore and the established reference ranges for FibroScan, 85.7% and 89.0% of the patients had an identical result for F0-1, F2, F3, and F4, as compared with liver biopsy. The concordance rate between BioFibroScore and FibroScan was 80.7%. BioFibroScore overestimated and underestimated the stage of hepatic fibrosis in 8.3% and 6.0% patients, and most patients had one stage error. Among patients with failed FibroScan assessment, 82.9% of them were correctly diagnosed by BioFibroScore. Bootstrap analysis for BioFibroScore showed the diagnostic accuracy was 80.9-88.4%. CONCLUSIONS BioFibroScore is accurate to assess the stage of hepatic fibrosis in HCV-infected patients. Applying this noninvasive test can substantially reduce the need for invasive liver biopsy and can play a role for fibrosis evaluation when FibroScan assessment was unavailable or unreliable.

Yu ML. Hepatitis C treatment from "response-guided" to "resource-guided" therapy in the transition era from interferon-containing to interferon-free regimens. J Gastroenterol Hepatol 2017; 32:1436-1442. [PMID: 28124463 DOI: 10.1111/jgh.13747] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2016] [Revised: 01/17/2017] [Accepted: 01/22/2017] [Indexed: 12/13/2022]
Abstract
Peginterferon/ribavirin has been the standard-of-care for chronic hepatitis C virus (HCV) infections: 48 weeks for genotype 1 or 4 (HCV-1/4) and 24 weeks for HCV-2/3. Response-guided therapy recommended shorter 24- and 16-week regimens for HCV-1 with lower baseline viral loads (< 400 000-800 000 IU/mL) and rapid virological response (RVR, undetectable HCV RNA at week 4) and HCV-2/3 with RVR, respectively; and extending to 72 and 48 weeks for HCV-1 slower responders and HCV-2 non-RVR patients, respectively, to improve the efficacy. The progress of directly acting antivirals (DAA), moving from interferon-containing regimens in 2011 to interferon-free regimens in 2013, has greatly improved the treatment success. Interferon-containing regimens include boceprevir or telaprevir or simeprevir or daclatasvir plus peginterferon/ribavirin, 24-48 weeks, for HCV-1 or 4. However, adding these DAA has no benefit for HCV-1 with lower baseline viral loads/RVR. Instead, 12-week sofosbuvir plus peginterferon/ribavirin attained sustained virological response rates of > 90% for HCV-1/3-6. Interferon-free regimens include two main categories: NS5B nucleotide inhibitor (sofosbuvir)-based regimens and NS3/4A inhibitor/NS5A inhibitor-based regimens (daclatasvir/asunaprevir, paritaprevir/r/ombitasvir/dasabuvir and grazoprevir/elbasvir). About 8-24 weeks interferon-free regimens could achieve sustained virological response rates of 82-99% for corresponding HCV genotypes. Although the newly DAA interferon-free regimens have high efficacy and safety, the huge budget impact increases the treatment barriers. The current recommendation should, therefore, base on the availability, indication, and cost-effectiveness in the transition era of DAA. Based on the concept of "resource-guided therapy," peginterferon/ribavirin might be applied for easy-to-treat interferon-eligible patients in resource-constrained areas. Prioritizing patients for interferon-free regimens according to "time-degenerative factors" (age and fibrosis) is justified before the regimens becoming available and affordable.

Abstract
Infection with the hepatitis C virus (HCV) may progress toward chronic hepatitis, liver cirrhosis, and liver cancer. A therapy for patients with chronic HCV infection is the combination of pegylated interferon-α with ribavirin, which increases the rate of sustained virological response (SVR) to 56%. However, a practical biomarker to predict SVR is lacking. T cells expressing the CD45RA isoform are considered naive, and antigenic stimulation converts them to CD45RO+. CD45RO+ T cells exhibit immediate response and high lymphokine production, leading to the maintenance and upregulation of immune reactions. The aim of this study is to clarify the proportions of CD45RA+ and CD45RO+ T cells associated with rapid virological response and SVR. We collected blood samples from 32 HCV patients receiving the combined treatment. The samples were collected before, during 4th, 12th, and 24th therapy weeks, and 4th week posttherapy, and their T cell populations were analyzed using flow cytometry. Twenty-nine patients (90.6%) achieved SVR. There were significant declines in proportions of CD45RA+ cells during 4th, 12th, and 24th therapy weeks, and significant increases in proportions of CD45RO+ cells during 24th therapy week and 4th week posttherapy (P < 0.05). Patients undergoing hepatitis C therapy exhibited lowered CD45RA+ cell proportions and increased CD45RO+ cell proportions. This effect may be important in a patient's response to pegylated interferon-α with ribavirin therapy.

Abstract
Attachment of polyethylene glycol (PEG) molecules to nanoparticles (PEGylation) is a widely-used method to improve the stability, biocompatibility and half-life of nanomedicines. However, the evaluation of the PEGylated nanomedicine pharmacokinetics (PK) requires the decomposition of particles and purification of lead compounds before analysis by high performance liquid chromatography (HPLC), mass spectrometry, etc. Therefore, a method to directly quantify un-decomposed PEGylated nanoparticles is needed. In this study, we developed anti-PEG bioparticles and combined them with anti-PEG antibodies to generate a quantitative enzyme-linked immunosorbent assay (ELISA) for direct measurement of PEGylated nanoparticles without compound purification. The anti-PEG bioparticles quantitative ELISA directly quantify PEG-quantum dots (PEG-QD), PEG-stabilizing super-paramagnetic iron oxide (PEG-SPIO), Lipo-Dox and PEGASYS and the detection limits were 0.01 nM, 0.1 nM, 15.63 ng/mL and 0.48 ng/mL, respectively. Furthermore, this anti-PEG bioparticle-based ELISA tolerated samples containing up to 10% mouse or human serum. There was no significant difference in pharmacokinetic studies of radiolabeled PEG-nanoparticles (Nano-X-111In) through anti-PEG bioparticle-based ELISA and a traditional gamma counter. These results suggest that the anti-PEG bioparticle-based ELISA may provide a direct and effective method for the quantitation of any whole PEGylated nanoparticles without sample preparation.

Abstract
Data are limited on the effectiveness and safety of peginterferon plus ribavirin in HIV-infected Asian patients with acute or chronic HCV infection. HIV-infected Taiwanese patients with acute HCV infection received peginterferon plus weight-based ribavirin for 24 weeks (n = 24), and those with chronic HCV genotype 1 or 6 (HCV-1/6) and HCV genotype 2 or 3 (HCV-2/3) infection received response-guided therapy for 12-72 and 24-48 weeks, respectively (n = 92). The primary endpoint was sustained virologic response (SVR), defined as undetectable HCV RNA 24 weeks off-therapy. The SVR rates were 83% and 72% in patients with acute and chronic HCV infection (p = 0.30), and 68% and 72% in patients with chronic HCV-1/6 and HCV-2/3 infection (p = 0.48), respectively. While no factors predicted SVR in acute HCV and chronic HCV-2/3 infection, age (odds ratio [OR] per 1-year increase: 0.88, 95% confidence interval [CI]: 0.78-0.99, p = 0.04), HCV RNA (OR per 1-log10 increase: 0.18, 95% CI: 0.03-0.98, p = 0.03), IL28B genotype (OR: 5.52, 95% CI: 1.55-12.2, p = 0.02), and RVR (OR: 9.62, 95% CI: 3.89-15.3, p = 0.007) predicted SVR in chronic HCV-1/6 infection. In conclusion, the SVR rates of peginterferon plus ribavirin for 24 weeks and for response-guided 12-72 weeks are satisfactory in HIV-infected Taiwanese patients with acute and chronic HCV infection.

Peginterferon alfa-2a plus Weight-Based or Flat-Dose Ribavirin for Treatment-Naïve Hepatitis C Virus Genotype 2 Rapid Responders: A Randomized Trial. Sci Rep 2015; 5:15255.

Abstract
The impact of ribavirin (RBV) dosage on sustained virologic response (SVR) rates remains elusive in hepatitis C virus genotype 2 (HCV-2) rapid responders receiving 16 weeks of peginterferon (Peg-IFN) plus RBV. Treatment-naïve HCV-2 patients with rapid virologic response (RVR) received Peg-IFN alfa-2a 180 μg/week plus weight-based RBV (1,000 or 1,200 mg/day; cut-off body weight: 75 kg) for 6 weeks, and then randomly received Peg-IFN alfa-2a 180 μg/week plus weight-based (1,000 or 1,200 mg/day; n = 247) or flat-dose (800 mg/day; n = 246) RBV for additional 10 weeks. The primary endpoint was SVR24. Patients receiving weight-based and flat-dose RBV therapies had comparable SVR24 rates (93.5% versus 91.9%, P = 0.49). The risk differences (RDs) of SVR24 receiving weight-based and flat-dose RBV arms were 7.1% [95% CI: 0.7% to 13.6%] in males, and -5.8% [95% CI: -12.1% to 0.5%] in females (interaction P = 0.01). The SVR24 rate was higher in males receiving ≥13 mg/kg/day than those receiving <13 mg/kg/day (96.3% versus 85.1%, P = 0.001). In conclusion, Peg-IFN alfa-2a plus weight-based or flat-dose RBV for 16 weeks provides comparable SVR24 rates in treatment-naïve HCV-2 rapid responders. However, males should receive weight-based RBV to achieve a high SVR24 rate.
