Abstract
Mutations in the non-structural protein regions of hepatitis C virus (HCV) are a cause of a non-sustained virological response (SVR) to treatment with direct-acting antivirals (DAAs) for chronic hepatitis; however, there are non-SVR cases without these mutations. In this study, we examined immune cell profiles in peripheral blood before and after ombitasvir/paritaprevir/ritonavir treatment and screened for genes that could be used to predict the therapeutic effects of DAAs. Fluorescence-activated cell sorting analysis indicated that the median frequencies of programmed cell death-1-positive (PD-1+) effector regulatory T cells (eTregs), PD-1+CD8+ T cells, and PD-1+Helper T cells were decreased significantly in SVR cases, but without significant changes in non-SVR cases. The frequency of PD-1+ naïve Tregs was significantly higher in the SVR group than in the non-SVR group before and after treatment. Similar results were found in patients treated with other DAAs (e.g., daclatasvir plus asunaprevir) and supported an immune response after HCV therapy. RNA-sequencing analysis indicated a significant increase in the expression of genes associated with the immune response in the SVR group, while genes related to intracellular and extracellular signal transduction were highly expressed in the non-SVR group. Therefore, we searched for genes associated with PD-1+ eTregs and CD8+ T cells that were significantly different between the SVR and non-SVR groups and found that T-box transcription factor 21 was associated with the non-SVR state. These results indicate that PD-1-related signaling pathways are associated with a non-SVR mechanism after DAAs treatment separate from mutation-related drug resistance.

Abstract
Human enteroviruses are the major pathogens causing hand-foot-and-mouth disease in infants and young children throughout the world, and infection with enterovirus is also associated with severe complications, such as aseptic meningitis and myocarditis. However, there are no antiviral drugs available to treat enteroviruses infection at present. In this study, we found that 4'-fluorouridine (4'-FlU), a nucleoside analog with low cytotoxicity, exhibited broad-spectrum activity against infections of multiple enteroviruses with EC50 values at low micromolar levels, including coxsackievirus A10 (CV-A10), CV-A16, CV-A6, CV-A7, CV-B3, enterovirus A71 (EV-A71), EV-A89, EV-D68, and echovirus 6. With further investigation, the results indicated that 4'-FlU directly interacted with the RNA-dependent RNA polymerase of enterovirus, the 3D pol, and impaired the polymerase activity of 3D pol, hence inhibiting viral RNA synthesis and significantly suppressing viral replication. Our findings suggest that 4'-FlU could be promisingly developed as a broad-spectrum direct-acting antiviral agent for anti-enteroviruses therapy.

Abstract
BACKGROUND The chronic kidney disease (CKD) population, including kidney transplant recipients (KTRs) and subjects on renal replacement therapy, is particularly vulnerable to unfavorable outcomes from chronic hepatitis C (CHC). Currently, there are oral direct-acting antiviral agents (DAAs) available to eradicate the virus with favorable short-term outcomes; however, their long-term effects are lacking. The aim of the study is to assess the long-term efficacy and safety of DAA therapy in the CKD population. METHODS An observational, cohort single-center study was performed. Fifty-nine CHC subjects with CKD, treated with DAAs between 2016 and 2018, were enrolled in the study. Safety and efficacy profiles were assessed, including sustained virologic response (SVR), occult hepatitis C infection (OCI) incidence, and liver fibrosis. RESULTS SVR was achieved in 96% of cases (n = 57). OCI was diagnosed only in one subject following SVR. Significant liver stiffness regression was observed 4 years after SVR compared to baseline values (Mdn = 6.1 kPa, IQR = 3.75 kPa; 4.9 kPa, IQR = 2.9 kPa), p < 0.001. The most common adverse events were anemia, weakness, and urinary tract infection. CONCLUSION DAAs provide a safe and effective cure for CHC in both CKD patients and KTRs with a favorable safety profile in the long-term follow-up.

Abstract
BACKGROUND Second generation direct acting antivirals (DAAs) drastically changed the landscape of chronic HCV (CHCV). Aim of this paper was to assess the effectiveness of DAAs, also looking at the demographic characteristics of subjects enrolled. RESEARCH DESIGN AND METHODS Ambispective multi-center real-life study conducted among patients with CHCV treated with DAAs in Campania Region (Southern Italy). Patient were enrolled in two cohorts according to time of enrolment. RESULTS 1,479 patients were enrolled. Patients aged ≥60 years were 74.7% in the historic cohort (953 patients) and 70.2% in the prospective cohort (526 patients. Patients aged ≥ 60 years showed a higher prevalence of genotype 1b (p<0.001) and 2 (p<0.001), while patients aged < 60 years showed a higher prevalence of genotype 1a (p<0.001), 3 (p<0.001) and 4 (p<0.05). SVR12 was 98.5% in both cohorts. SVR12 was similar among patients of the prospective cohort aged < and ≥ 60 years (99.4% vs 98.1%). SVR12 among patients with and without cirrhosis was 96.0% and 98.9%, respectively. CONCLUSIONS DAAs provide high efficacy also in harder to treat patients. The effectiveness of DAAs is leading to a shift in patients characteristics with a greater prevalence of younger subjects and persons with mild liver disease.

Non-Invasive Indirect Markers of Liver Fibrosis after Interferon-Free Treatment for Hepatitis C. J Clin Med 2021; 10:jcm10173951.

Abstract
The effectiveness of interferon-free therapy during the course of HCV infection has already been confirmed. Liver fibrosis can be assessed in several ways, from biopsies to imaging tests. The present study evaluates the usefulness of non-invasive indirect biomarkers of liver fibrosis (APRI, GAPRI, FORNS, FIB-4, the AP index and HUI score) as markers of the effective treatment of HCV with the 3D regimen. Blood samples were collected from 70 patients suffering from chronic hepatitis C. Patients received the 3D AbbVie regimen for hepatitis C. All patients had HCV genotype 1b. The APRI, GAPRI, FIB-4, FORNS, HUI and AP index (age–platelet score) values were calculated with their respective algorithms. The stage of fibrosis was evaluated on the basis of a liver biopsy and confirmed by FibroScan-based transient elastography. An undetectable level of HCV RNA after 12 weeks of treatment with the 3D regimen indicates 100% eradication of hepatitis C virus. After the treatment, non-invasive indirect markers of liver fibrosis achieved levels below the limit for significant fibrosis, Thus, non-invasive indirect biomarkers of hepatic fibrosis failed to detect the presence of significant fibrosis, which was proved in histopathological examination. However, the eradication of hepatitis C virus by means of the 3D regimen treatment does not mean that patients were completely cured.

Abstract
Hepatitis C virus genotype 4 (HCV-GT4) is a risk factor for cirrhosis, hepatocellular carcinoma and liver failure. A combination of three new direct-acting antivirals ombitasvir, paritaprevir, and ritonavir has been recommended for treatment of HCV-GT4 infection. The current study was aimed to assess the efficacy and safety of this combination plus ribavirin in non-cirrhotic, treatment-naïve and -experienced Egyptians with HCV-GT4 infection in a real-world setting. A total of 255 Egyptians with HCV-GT4 infection were enrolled, including 82 treatment-experienced and 173 treatment-naïve patients. All of them completed 12-week treatment protocol of ombitasvir, paritaprevir and ritonavir as an oral dose combination with ribavirin. Virological response (VR) was measured, as well as the biochemical parameters related to treatment efficacy and adverse events at baseline and after treatment, at 4 (VR4) and 12 (VR12) weeks post-treatment. The results showed that the VR4 rates were 98.8% in both groups, and VR12 rates were 97.7% and 96.3% in treatment-naïve and -experienced patients, respectively, with no significant differences found between the groups concerning VR4 (P=0.9) and VR12 (P=0.3). The most common adverse events were headache and fatigue, which were significantly more common (P=0.001 and 0.003, respectively) in treatment-experienced than in treatment-naïve group. The quadruple regimen was well-tolerated, and the reported adverse events were generally mild to moderate. This real-world setting study confirms that the combination of ombitasvir, paritaprevir, ritonavir, and ribavirin is highly effective in the treatment of HCV- GT4 infection with a good safety and tolerability profile.

Abstract
BACKGROUND Isoquinoline analogs are an important, structurally diverse class of compounds that are extensively used as pharmaceuticals. Derivatives containing the isoquinoline scaffold have become a focus of therapeutic research because of their wide range of biological characteristics. Examples of these drugs, many of which are in clinical application or at the pre-clinical stage, are used to treat a broad swathe of ailments, such as tumors, respiratory diseases, infections, nervous system diseases, cardiovascular and cerebrovascular diseases, endocrine and metabolic diseases. METHODS Data were collected from PubMed, Web of Science, and SciFinder, through searches of drug names. RESULTS At least 38 isoquinoline-based therapeutic drugs are in clinical application or clinical trials, and their chemical structure and pharmacokinetics are described in detail. CONCLUSION The isoquinoline ring is a privileged scaffold which is often preferred as a structural basis for drug design, and plays an important role in drug discovery. This review provides a guide for pharmacologists to find effective preclinical/clinical drugs and examines recent progress in the application of the isoquinoline scaffold.

Abstract
Abstract
Background: Hepatitis C virus can be eradicated with antiviral therapy, thus reducing the risk of disease progression and death associated with the final stage of liver disease.
Methods: 241 patients received PrOD+RBV for 12 weeks. Clinical and laboratory data were assessed at baseline, week 4, 8, 12 (end of treatment, EOT), and 12 weeks after therapy (sustained virological response, SVR). Subsequently, biological and virological measurements were performed at least 48 weeks after obtaining SVR12 in responder patients.
Results: Per protocol SVR12 rate was 97,6%. Severe adverse events were reported in 3 patients (1.24%) and led to treatment discontinuation (liver decompensation). One 58-year-old patient who completed the treatment died before SVR evaluation due to acute mesenteric ischemia (not related to antiviral therapy). Baseline total bilirubin above 2 mg/dl can be considered a predictive factor for non-response to PrOD+RBV treatment (p = 0.004). Of the 30 patients evaluated at least 48 weeks after SVR no one presented relapses, with no statistically significant differences in biological parameters changes and no adverse events were noted during the 48-week follow up period.
Conclusion: Our study revealed the high effectiveness and good safety profile of PrOD +RBV in patients with genotype-1b HCV compensated cirrhosis (Child Pugh A) which were maintained during a 48-week period after treatment finalization.

Abstract
BACKGROUND In England, choice of hepatitis C therapy is determined by national contracts that change with time, facilitating comparisons between different regimens. England has a diverse population with hepatitis C including large proportions of uncommon viral genotypes. AIM To evaluate efficacy of directly acting anti-viral treatments for hepatitis C in England using real-world data from the national treatment registry. METHODS Sustained virological response (SVR) rates 12 weeks after treatment completion for patients treated between 2014 and August 2018 who attended for SVR tests were analysed in univariate subgroups using Chi-squared tests. Multivariate models were constructed with clinically relevant variables to determine predictors of SVR and evaluate the impact of treatment regimens. RESULTS SVR data were available on 14,603 treated patients. The overall SVR rate was 95.59% [95% CI 95.25%-95.91%]. Multivariable regression modelling in patients with genotype 1 infection showed that the odds of SVR with elbasvir/grazoprevir were higher than for those treated with sofosbuvir/ledipasvir (OR 1.891, 95% CI 1.072-3.336, P = 0.028). For genotype 3, we found no significant difference between any of the treatment regimens. Patients who completed at least one third of the planned treatment duration achieved SVR rates in excess of 80%. CONCLUSIONS All of the currently licensed hepatitis C direct-acting anti-viral regimens had similar efficacy (>95%) in an unselected population. Noncompletion of planned treatment duration still resulted in over 80% SVR rates provided that more than one third of treatment was completed.

PURPOSE Since 2017 treatment-naïve patients infected with genotype 1b of hepatitis C virus and minimal or moderate fibrosis can be treated with Ombitasvir/Paritaprevir/ritonavir + Dasabuvir (OPrD) for 8 weeks according to updated Summary of Product Characteristics. The aim of our study was to assess the comparative efficacy of 8 and 12-weeks therapy with OPrD in large cohort of patients eligible for 8 weeks regimen treated in real-world setting. MATERIALS AND METHODS We analysed data of 3067 HCV genotype 1b infected patients treated with OPrD between 2015 and 2017. Final analysis included patients with none, minimal or moderate fibrosis (F0-F2). RESULTS A total of 771 patients were enrolled in the study, including 197 (26%) treated for 8-weeks and 574 patients fulfilling criteria for 8-weeks but assigned to 12-weeks regimen. Majority of patients had no or minimal fibrosis (F0-F1). Longer treatment duration was more often administered in patients with moderate fibrosis, comorbidities, concomitant medications. SVR was achieved in 186 (94%) patients treated for 8 weeks and 558 (97%) for 12 weeks (p = 0.07). After exclusion of lost to follow-up patients, sustained virological response (SVR) rate reached 95% and 99%, respectively (p = 0.01). We were not able to identify factors associated with non-response. CONCLUSIONS This real-word experience study confirmed similar, high effectiveness of 8 and 12-weeks regimens of OPrD in genotype 1b HCV infected patients with non-advanced fibrosis. Despite of reduced SVR rate after 8-weeks regimen, there is no need to extend therapy to 12-weeks in vast majority of such patients and no need to add ribavirin.

Intention-to-treat assessment of glecaprevir + pibrentasvir combination therapy for patients with chronic hepatitis C in the real world. Hepatol Res 2019; 49:1365-1373. [PMID: 31323165 DOI: 10.1111/hepr.13410] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2019] [Revised: 06/20/2019] [Accepted: 07/11/2019] [Indexed: 02/08/2023]
Abstract
AIMS We assessed the problems and efficacy of glecaprevir + pibrentasvir (GLE/PIB) therapy for patients infected with hepatitis C virus (HCV) in the real world. METHOD A total of 423 patients infected with HCV who started treatment at eight different centers in Japan were enrolled in the study. Glecaprevir (300 mg) and pibrentasvir (120 mg) were given once daily for 8 weeks to 246 non-cirrhotic direct-acting antiviral (DAA)-naive patients with HCV genotype (GT)-1 or -2, and for 12 weeks to patients who: were DAA-naive cirrhotic (n = 55), had experienced DAA failure (n = 78), were cirrhotic and had DAA failure (n = 37), and were other GT-1/2 (n = 7). Anti-HCV efficacy was defined as a sustained virologic response 12 weeks post-treatment (SVR12). The evaluation was undertaken in an intention-to-treat (ITT) population and in patients who were assessed at SVR12 (modified ITT population). RESULTS In the ITT population, 220 (89%) patients on the 8-week regimen and 164 (93%) patients on the 12-week regimen achieved SVR12. The 30 dropout patients were predominantly men and with GT-2. All other DAA-naive GT-1 patients achieved SVR12. The 12-week regimen resulted in 100% SVR12 in 41 GT-2 patients. Nine patients did not achieve SVR12: two DAA naive with GT-2a, two GT-3b patients, two GT-1 patients with discontinuation, and three other GT-1 patients with a history of DAA failure. Four of seven patients who discontinued treatment due to severe adverse effects were more than 75 years old. CONCLUSIONS Glecaprevir + pibrentasvir had a remarkable anti-HCV effect in GT-1 and GT-2 patients, but not in GT-3b patients. Although this therapy was reasonably safe, it is necessary to carefully consider elderly and dropout patients.

Real-world safety and efficacy of paritaprevir/ritonavir/ombitasvir plus dasabuvir ± ribavirin in patients with hepatitis C virus genotype 1 and advanced hepatic fibrosis or compensated cirrhosis: a multicenter pooled analysis. Sci Rep 2019; 9:7086. [PMID: 31068655 PMCID: PMC6506536 DOI: 10.1038/s41598-019-43554-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2018] [Accepted: 04/27/2019] [Indexed: 02/08/2023] Open
Abstract
Paritaprevir/ritonavir, ombitasvir, and dasabuvir (PrOD) with or without ribavirin shows favorable results in hepatitis C virus genotype 1 (HCV-1) patients in terms of safety and efficacy, but real-world data remain limited for those with advanced hepatic fibrosis (fibrosis 3, F3) or compensated cirrhosis (F4). A total of 941 patients treated in four hospitals (the Keelung, the Linkuo, the Chiayi and the Kaohsiung Chang Gung Memorial Hospital) through a nationwide government-funded program in Taiwan were enrolled. Patients with HCV and advanced hepatic fibrosis or compensated cirrhosis received 12 weeks of PrOD in HCV-1b and 12 or 24 weeks of PrOD plus ribavirin therapy in HCV-1a without or with cirrhosis. Advanced hepatic fibrosis or compensated cirrhosis was confirmed by either ultrasonography, fibrosis index based on 4 factors (FIB-4) test, or transient elastography/acoustic radiation force impulse (ARFI). The safety and efficacy (sustained virologic response 12 weeks off therapy, SVR12) were evaluated. An SVR12 was achieved in 887 of 898 (98.8%) patients based on the per-protocol analysis (subjects receiving ≥1 dose of any study medication and HCV RNA data available at post-treatment week 12). Child-Pugh A6 (odds ratio: 0.168; 95% confidence interval (CI): 0.043–0.659, p = 0.011) was the only significant factor of poor SVR12. Fifty-four (5.7%) patients were withdrawn early from the treatment because of hepatic decompensation (n = 18, 1.9%) and other adverse reactions. Multivariate analyses identified old age (odds ratio: 1.062; 95% CI: 1.008–1.119, p = 0.024) and Child-Pugh A6 (odds ratio: 4.957; 95% CI: 1.691–14.528, p = 0.004) were significantly associated with hepatic decompensation. In conclusion, this large real-world cohort proved PrOD with or without ribavirin to be highly effective in chronic hepatitis C patients with advanced hepatic fibrosis or compensated cirrhosis. However, Child-Pugh A6 should be an exclusion criterion for first-line treatment in these patients.

Abstract
OBJECTIVE Direct-acting antiviral agents (DAAs) have been approved for treating hepatitis C virus (HCV) infection in China. However, they are substantially more expensive. The current analysis will investigate the cost-effectiveness of novel regimens compared with pegylated interferon and ribavirin (PR) therapies for informing Chinese decision-makers. METHODS A Markov model was developed to measure economic and health outcomes of novel regimens for genotype 1b, 2, 3, and 6 HCV infections compared with PR treatment. Clinical, cost, and utility inputs were gathered from published sources. Discounted quality-adjusted life-years (QALYs), costs, and incremental cost-effectiveness ratios (ICERs) are shown. The uncertainty was facilitated by one-way and probabilistic sensitivity analyses. RESULTS For genotype 1b HCV infection, the combination of paritaprevir, ritonavir, ombitasvir and dasabuvir was cost-saving compared with four competing alternatives. The ICERs of sofosbuvir plus ribavirin for genotypes 2 and 3 were lower than the threshold ($18,234/QALY). Among available strategies for patients with genotype 6, sofosbuvir in combination with ribavirin was the cost-saving alternative compared with PR. The results were robust to sensitivity analyses. CONCLUSIONS For both genotype 1b and 6 HCV infections in the context of Chinese patients, there were combinations of DAAs that were cost-saving compared with the usual PR treatment, and cost-effective for genotypes 2 and 3.

Abstract
AIM Although the development of new direct-acting antivirals (DAAs) for the treatment of chronic hepatitis C virus (HCV) infection has markedly advanced, the effects of cirrhosis on DAA treatment remain unclear. We aimed to clarify the impact of cirrhosis on DAA treatment of patients infected with HCV. METHODS This large-scale, multicenter, retrospective study consisted of 2130 HCV genotype 1b-infected patients who were treated with one of the following DAA combination therapies: asunaprevir/daclatasvir (ASV/DCV), ledipasvir/sofosbuvir (LDV/SOF), or paritaprevir/ombitasvir/ritonavir (PTV/OBV/r). Ninety-two patients (4.3%) previously received DAA-based treatment. Seven hundred and forty-five patients (34.9%) had cirrhosis. RESULTS Overall, the sustained virologic response (SVR) rate was 93.0%. The SVR rates in patients who received ASV/DCV, LDV/SOF, or PTV/OBV/r were 90.0%, 96.9%, and 97.6%, respectively. The SVR rate in patients with cirrhosis (89.1%) was significantly lower than that in patients without cirrhosis (95.1%, P = 6.94 × 10-7 ). In the multivariate analysis for the overall cohort, absence of cirrhosis (P = 1.26 × 10-3 ), no previous DAA-based treatment (P = 2.54 × 10-14 ), low HCV-RNA levels (P = 1.64 × 10-6 ), wild-type non-structural protein 5A L31/Y93 (P = 7.33 × 10-13 ), and DAA regimen (LDV/SOF or PTV/OBV/r) (P = 1.92 × 10-14 ) were independent factors contributing to SVR. Except for patients with DAA-based treatment history, absence of cirrhosis (P = 2.15 × 10-3 ; odds ratio, 2.51) was an independent factor contributing to SVR in 2038 DAA-naïve patients. CONCLUSION This study suggests that the presence of cirrhosis reduces the SVR rate of DAA treatment, regardless of the type of DAA treatment.

Abstract
Interferon-alpha (IFN-α)-based therapy is associated with several hematological adverse events in hepatitis C virus (HCV)-infected patients with advanced fibrosis. We performed this study to evaluate the association between Fibrosis-4 (Fib-4) index and hematological adverse events in patients with chronic HCV infection, undergoing IFN-α-based triple therapy. We included 120 HCV-infected patients, receiving triple therapy: weekly PegIFN-α, daily ribavirin (1,000-1,200 mg), and daily sofosbuvir (400 mg) for 12 weeks. We compared Fib-4 scores for patients who developed hematological adverse events at weeks 4 (w4) and w12 of treatment and w12 post-treatment versus those who did not. Treatment with the aforementioned triple regimen was associated with a sustained virological response (SVR)-12 rate of 93.9%. We found no significant associations (P > 0.05) between SVR12 rate and the degree of fibrosis or the risk of hematological adverse events. The Fib-4 score could predict patients who developed hematological adverse events (anemia, leukopenia, and neutropenia) in the first month of treatment, but not in later stages. A Fib-4 cutoff value of 3.59 had high specificity for anemia, leukopenia, and neutropenia (85.1%, 87.2%, and 88.2%, respectively), but had low sensitivity for detecting the 3 events. In conclusion, the Fib-4 score may predict early hematological adverse effects in HCV-infected patients on IFN-based triple therapy.

Abstract
Background Data on the treatment of patients with hepatitis C virus (HCV)/human immunodeficiency virus (HIV) coinfection remains limited. A comprehensive analysis was performed to evaluate the efficacy and safety of ombitasvir (OBV)/paritaprevir (PTV)/ritonavir(r) ± dasabuvir (DSV) ± ribavirin (RBV) for treatment in HCV/HIV coinfected patients. Methods We systematically searched and included studies that enrolled patients with HIV/HCV coinfection using the OBV/PTV/r ± DSV ± RBV regimens and reported sustained virological response after 12 weeks (SVR12) end-of-treatment. Heterogeneity of results was assessed and pooled SVR rates were computed with 95% confidence intervals (95%CI). Subgroup analysis and assessment of publication bias through Egger’s test were further performed. Results Ten studies containing 1358 coinfected patients were included in this study. The pooled estimate of SVR12 was 96.3% (95%CI: 95.1–97.4). Subgroup analysis showed that pooled SVR12 rate was 96.2% (95% CI: 94.8–97.4) for patients with genotype (GT) 1 and 98.8% (95% CI: 95.1–100.0) for those with GT4. The SVR12 rates for the treatment-naïve (TN) and treatment-experienced (TE) patients were 96.8% (95% CI, 94.8–98.5) and 98.9% (95% CI, 96.4–100.0), respectively. Pooled SVR12 rate was 97.8(95%CI: 94.6–99.8) for patients with cirrhosis and 96.7% (95%CI: 95.3–97.8) without cirrhosis. The pooled incidence of any adverse events (AEs) and serious adverse events (SAEs) was 73.9% (95%CI: 38.1–97.6) and 2.7% (95%CI: 0.0–9.5). Publication bias did not exist in this study. Conclusions The comprehensive analysis showed high efficacy for the OBV/PTV/r ± DSV ± RBV regimen in patients coinfected with HIV and HCV, regardless of genotypes, history of treatment and the presence or absence of cirrhosis.

Sustained Virological Response in Special Populations with Chronic Hepatitis C Using Interferon-Free Treatments: A Systematic Review and Meta-analysis of Observational Cohort Studies. Clin Drug Investig 2018; 38:389-400.

Abstract
BACKGROUND AND OBJECTIVES Hepatitis C treatment has changed considerably in recent years, and many interferon (IFN)-free therapies are now available. Considering the high rates of sustained virological response (SVR) presented by clinical trials for these treatments, high rates of effectiveness are also expected in real-world clinical practice. Hence, this study aimed to conduct a systematic review and meta-analysis of observational cohort studies to evaluate the clinical effectiveness and safety of IFN-free therapies for hepatitis C. METHODS The search was performed in four electronic databases and included cohort studies that evaluated IFN-free schemes and provided data on SVR at 12 weeks after the end of treatment (SVR12) as the primary outcome. Overall and subgroup meta-analyses of patients' clinical conditions (e.g. co-infection with human immunodeficiency virus (HIV), cirrhosis, liver transplant, specific genotypes, and other conditions) were performed. RESULTS Sixty-eight studies encompassing a total of 24,151 patients were included for quantitative and qualitative analyses, evaluating six treatments: sofosbuvir with ledipasvir, daclatasvir, or simeprevir; daclatasvir with asunaprevir; paritaprevir/ritonavir in combination with ombitasvir and dasabuvir; and sofosbuvir with ribavirin. The overall analysis showed SVR rates of 88-96% for all treatments except sofosbuvir combined with ribavirin, which had SVR rates of approximately 80%. The results of subgroup analyses showed that the genotype 3 virus appears to be the most difficult to treat. CONCLUSION In order to choose the best treatment option, it is necessary to consider the patients' conditions and characteristics. In conclusion, the use of IFN-free therapies meets the high expectations created by clinical trials, including patients in special clinical conditions.

Abstract
PURPOSE Introduction of the direct-acting antivirals (DAAs) for treatment of chronic hepatitis C (CHC) infection has been challenging in all health systems. In Sweden, a national protocol for managed introduction was developed. It was optional, but all county councils agreed to implement and follow it. The purpose of this study was to study (a) cure rates among all patients initiated on treatment in 2014-2015, (b) prescribers' adherence to the drug recommendations and treatment eligibility criteria in the protocol, and (c) introduction rate in the six Swedish healthcare regions. METHOD A cross-sectional study where national data from the Prescribed Drug Register and the quality register InfCare Hepatitis defined the study population, and clinical data from the Patient Register and InfCare Hepatitis were used to monitor outcomes. Descriptive statistics were used. RESULTS A total of 3447 patients were initiated on treatment during 2014-2015. The overall cure rate, based on data from 85% of the cohort, was 96%, with variation between genotypes. Adherence to drug recommendations increased over time and varied between 43.2 and 94.2%. Adherence to the treatment eligibility criteria was initially 80% and increased to 87% when treatment restrictions were widened. The introduction rate differed initially between the regions and reached stable levels 15-18 months after the launch of the first DAA. CONCLUSION The estimated overall cure rate was 96%, with some variations between genotypes. A high level of adherence to the introduction protocol as well as similar introduction rates in the health care regions indicate that the introduction protocol, alongside with other measures taken, contributed considerably to a rapid uptake and equal distribution of DAAs in Sweden.
