Effectiveness and safety of original and generic sofosbuvir for the treatment of chronic hepatitis C: A real world study

Genotypes of Hepatitis C Virus and Efficacy of Direct-Acting Antiviral Drugs among Chronic Hepatitis C Patients in a Tertiary Care Hospital

Hepatitis C virus (HCV) chronic infection is a major causative factor for several chronic liver diseases, including liver cirrhosis, liver cell failure, and hepatocellular carcinoma. The HCV has seven major genotypes. Genotype 4 is the most prevalent genotype in the Middle East, including Saudi Arabia, followed by genotype 1. The HCV genotype affects the response to different HCV treatments and the progression of liver disease. Currently, combinations of direct-acting antiviral drugs (DAAs) approved for the treatment of HCV achieve high cure rates with minimal adverse effects. Because real-world data from Saudi Arabia about the efficacy of DAAs are still limited, this study was conducted to assess the effectiveness of DAAs in treating patients with chronic hepatitis C and to identify the variables related to a sustained virologic response (SVR) in a real-world setting in Saudi Arabia. This prospective cohort study included 200 Saudi patients with chronic HCV who were 18 years of age or older and had been treated with DAAs at King Abdul-Aziz Specialized Hospital in Taif, Saudi Arabia, between September 2018 and March 2021. The response to treatment was assessed by whether or not an SVR had been achieved at week 12 post treatment (SVR12). An SVR12 was reached in 97.5% of patients. SVR12 rates were comparable for patients of different ages, between men and women, and between patients with and without cirrhosis. In addition, the SVR12 rates did not differ according to the infecting HCV genotype. In this study, the presence of cirrhosis and the patient's gender were independent predictors of who would not reach an SVR12 (known here as the non-SVR12 group) according to the results of univariate and multivariate binary logistic regression analyses based on the determinants of SVR12. In this population of patients with chronic HCV infection, all DAA regimens achieved very high SVR12 rates. The patients' gender and the presence of cirrhosis were independent factors of a poor response.

Effectiveness and safety of generic and brand direct acting antivirals for treatment of chronic hepatitis C

BACKGROUND

Direct acting antivirals (DAAs) are a very effective treatment for hepatitis C virus (HCV). However, brand DAAs are expensive. The licensing of cheaper generic DAAs may address this issue, but there is a lack of clinical studies comparing the efficacy of generic vs brand DAA formulations.

AIM

To compare the efficacy and safety of generic against brand DAAs for chronic hepatitis C treatment in Bahrain.

METHODS

This was a retrospective observational study involving 289 patients with chronic HCV infection during 2016 to 2018. There were 149 patients who were treated with brand DAAs, while 140 patients were treated with generic DAAs. Commonly used DAAs were Ombitasvir/Paritaprevir/Ritonavir ± Dasabuvir ± Ribavirin, and Sofosbuvir/Daclatasvir ± Ribavirin. SVR at 12 wk post treatment was the main outcome variable.

RESULTS

Overall, 87 patients (30.1%) had cirrhosis and 68.2% had genotype 1 HCV infection. At 12 wk post treatment, SVR was achieved by 271 (93.8%) of the patients. In patients who were treated with generic medications, 134 (95.7%) achieved SVR at 12 wk post treatment, compared to 137 (91.9%) among those treated with brand medications (P = 0.19). Having cirrhosis [odds ratio (OR): 9.41, 95% confidence interval (CI): 2.47–35.84] and having HCV genotype 3 (OR: 3.56, 95%CI: 1.03–12.38) were significant independent predictors of not achieving SVR. Alanine transaminase, gamma-glutamyl transpeptidase, and total bilirubin levels decreased significantly following therapy with both generic and brand DAAs.

CONCLUSION

Generic and brand DAAs demonstrate comparable effectiveness in the treatment of chronic hepatitis C patients. Both are safe and equally effective in improving biochemical markers of hepatic inflammation.

Real-World Effectiveness of Direct-Acting Antiviral Regimens against Hepatitis C Virus (HCV) Genotype 3 Infection: A Systematic Review and Meta-Analysis

Patients with hepatitis C virus (HCV) genotype 3 (GT3) infection are resistant to direct-acting antiviral (DAA) treatments. This study aimed to analyze the effectiveness of sofosbuvir (SOF)+daclatasvir (DCV) ± ribavirin (RBV); SOF+velpatasvir (VEL)±RBV; SOF+VEL+voxilaprevir (VOX); and glecaprevir (GLE)+pibrentasvir (PIB) in the treatment of HCV GT3-infected patients in real-world studies. Articles were identified by searching the PubMed, EMBASE, and Cochrane Library databases from January 1, 2016 to September 10, 2019. The meta-analysis was conducted to determine the sustained virologic response (SVR) rate, using R 3.6.2 software. Thirty-four studies, conducted on a total of 7328 patients from 22 countries, met the inclusion criteria. The pooled SVR rate after 12/24 weeks of treatment was 92.07% (95% CI: 90.39-93.61%) for the evaluated regimens. Also, the SVR rate was 91.17% (95% CI: 89.23-92.94%) in patients treated with SOF+DCV±RBV; 95.08% (95% CI: 90.88-98.13%) in patients treated with SOF+VEL±RBV; 84.97% (95% CI: 73.32-93.91%) in patients treated with SOF+VEL+VOX; and 98.54% (95% CI: 96.40-99.82%) in patients treated with GLE+PIB. The pooled SVR rate of the four regimens was 95.24% (95% CI: 93.50-96.75%) in non-cirrhotic patients and 89.39% (95% CI: 86.07-92.33%) in cirrhotic patients. The pooled SVR rate was 94.41% (95% CI: 92.02-96.42%) in treatment-naive patients and 87.98% (95% CI: 84.31-91.25%) in treatment-experienced patients. The SVR rate of GLE+PIB was higher than other regimens. SOF+VEL+VOX can be used as a treatment regimen following DAA treatment failure.

HEPLA: A multicenter study on demographic and disease characteristics of patients with hepatitis C in Latin America

INTRODUCTION AND OBJECTIVES

Currently, there are limited data on the epidemiology and disease characteristics of patients with chronic hepatitis C (CHC) in Latin America. The primary objective of this study was to evaluate demographic and disease characteristics of patients with CHC in Latin America.

PATIENTS AND METHODS

HEPLA was a non-interventional, multicenter study of the epidemiology and disease characteristics of patients with CHC in Argentina, Brazil, Chile, Colombia, and Mexico.

RESULTS

Of the 817 included patients, the median age was 58 years, 53.9% were female, and 39.3% had cirrhosis. Overall, 41.2% were treatment naive, 49.8% were treatment experienced, and 8.9% were currently undergoing treatment. In patients with available data, genotype 1b accounted for 41.6% of infections, followed by genotype 1a (29.9%) and genotype 3 (11.3%). Probable mode of infection was transfusion in 46.8% of patients. Liver-related comorbidities were present in 26.4% of patients and non-liver-related comorbidities were present in 72.3%. Most patients (71.8%) received concomitant medications, with proton-pump inhibitors (20.8%) being the most commonly reported.

CONCLUSIONS

At the time the HEPLA study was carried out, the data from this cross-section of patients in Latin America showed that the CHC population has variation in disease and viral characteristics, with a minority of patients receiving treatment and many patients having advanced disease. Increased awareness and access to treatment are necessary in Latin America in order to meet the goal of hepatitis C virus elimination by 2030.

Effectiveness of direct-acting agents for chronic hepatitis C treatment in South America: A systematic review and meta-analysis

The effectiveness of direct-acting agents (DAAs) for hepatitis C treatment in limited-resource settings remains unclear. We estimated the pooled sustained virological response rates of DAA therapy in South America. We searched online databases for studies that reported 12-week sustained virological response (SVR12) to hepatitis C virus (HCV) treatment in individuals living in South America. Pooled SVR12 in intention-to-treat (ITT) and per-protocol were estimated. Additionally, using all studies with available data, the pooled relative risk (RR) of SVR12 using a random-effects model (DerSimonian-Laird) was estimated to compare effectiveness of DAAs in patients with or without cirrhosis, HIV co-infection or previous HCV therapy. Heterogeneity was assessed using the I² statistics. We identified 20 studies [14 manuscripts and 6 conference abstracts] comprising 7393 individuals from five countries [Brazil (n = 11), Argentina (n = 4), Chile (n = 1), Colombia (n = 1) and Peru (n = 1)] and two South-American collaborations. The pooled overall SVR12 rates [95% confidence interval (CI)] were 92.6% [90.2-94.7] and 95.5% [94.3-96.6] by ITT (11 studies; n = 4,153; I²  = 84.2%) and per-protocol analysis (15 studies; n = 4,833; I²  = 64.5%), respectively. The RR of SVR12 was similar in patients with or without HIV co-infection [4 studies; RR = 1.03 (0.99-1.07)] and those naive compared with treatment experimented-individuals [9 studies; RR = 1.01 (1.00-1.03)], but significantly higher in patients without cirrhosis compared with those with cirrhosis [11 studies; RR = 1.04 (1.02-1.05), P < .001]. DAAs are highly effective for HCV treatment in South America. The use of DAAs should be considered in limited-resource settings to decrease the burden of liver disease in HCV-infected patients.

Decompensated cirrhosis and liver transplantation negatively impact in DAA treatment response: Real-world experience from HCV-LALREAN cohort

INTRODUCTION

Although the effectiveness of direct-acting antivirals (DAAs) for the treatment of chronic hepatitis C virus (HCV) has been reported in real-world settings, predictive factors of treatment failure are lacking. Therefore, we sought to explore the baseline predictors of treatment response to DAAs.

METHODS

This was a prospective multicenter cohort study from the Latin American Liver Research Educational and Awareness Network (LALREAN) including patients who received DAA treatment from May 2016 to April 2019. A multivariate logistic regression model was conducted to identify variables associated with unachieved sustained virological response (SVR), defined as treatment failure (odds ratios [OR] and 95% confidence intervals [CIs]).

RESULTS

From 2167 patients (55.2% with cirrhosis) who initiated DAA therapy, 89.4% completed a full-course treatment (n = 1938). Median treatment duration was 12 weeks, and 50% received ribavirin. Definitive suspension due to intolerance or other causes was observed in only 1.0% cases (n = 20). Overall non-SVR12 was 4.5% (95% CI, 3.5-5.7). There were no significant differences in treatment failure according to HCV genotypes and the degree of fibrosis. Independently associated variables with DAA failure were liver function impairment according to the Child-Pugh score B OR, 2.09 (P = .06), Child-Pugh C OR, 11.7 (P < .0001); and liver transplant (LT) recipient OR, 3.75 (P = .01).

CONCLUSION

In this real-life setting, higher DAA treatment failure rates were observed in patients with decompensated cirrhosis and in LT recipients. These predictive baseline factors should be addressed to individualize the appropriate time-point of DAA treatment (NCT03775798; www.

Hepatitis C: How Good Are Real-Life Data and Do Generics Work

Chronic hepatitis C virus infection remains a national and global public health burden and is associated with significant morbidity and mortality. Oral direct-acting antiviral combination regimens have excellent tolerability and efficacy with rates exceeding 90%. Sustained virologic response is associated with significant improvements in clinical outcomes. However, translation of sustained virologic response rates from trials to community settings has been poor with interferon-based regimens. We review and summarize key datasets from major real-world observational cohort studies. We review preliminary data from oral generic direct-acting antiviral formulations. Future real-world studies are needed to further clarify optimal treatment strategies for difficult-to-treat populations.

Direct-Acting Antivirals and Hepatocellular Carcinoma: No Evidence of Higher Wait-List Progression or Posttransplant Recurrence

The association between direct-acting antivirals (DAAs) and hepatocellular carcinoma (HCC) wait-list progression or its recurrence following liver transplantation (LT) remains uncertain. We evaluated the impact of DAAs on HCC wait-list progression and post-LT recurrence. This Latin American multicenter retrospective cohort study included HCC patients listed for LT between 2012 and 2018. Patients were grouped according to etiology of liver disease: hepatitis C virus (HCV) negative, HCV+ never treated with DAAs, and HCV+ treated with DAAs either before or after transplantation. Multivariate competing risks models were conducted for both HCC wait-list progression adjusted by a propensity score matching (pre-LT DAA effect) and for post-LT HCC recurrence (pre- or post-LT DAA effect). From 994 included patients, 50.6% were HCV-, 32.9% were HCV+ never treated with DAAs, and 16.5% were HCV+ treated with DAAs either before (n = 66) or after LT (n = 98). Patients treated with DAAs before LT presented similar cumulative incidence of wait-list tumor progression when compared with those patients who were HCV+ without DAAs (26.2% versus 26.9%; P = 0.47) and a similar HCC-related dropout rate (12.1% [95% CI, 0.4%-8.1%] versus 12.9% [95% CI, 3.8%-27.2%]), adjusted for baseline tumor burden, alpha-fetoprotein values, HCC diagnosis after listing, bridging therapies, and by the probability of having received or not received DAAs through propensity score matching (subhazard ratio [SHR], 0.9; 95% CI, 0.6-1.6; P = 0.95). A lower incidence of posttransplant HCC recurrence among HCV+ patients who were treated with pre- or post-LT DAAs was observed (SHR, 0.7%; 95% CI, 0.2%-4.0%). However, this effect was confounded by the time to DAA initiation after LT. In conclusion, in this multicenter cohort, HCV treatment with DAAs did not appear to be associated with an increased wait-list tumor progression and HCC recurrence after LT.

Effectiveness of implementing a decentralized delivery of hepatitis C virus treatment with direct-acting antivirals: A systematic review with meta-analysis

Direct-acting agents (DAAs) for hepatitis C virus (HCV) treatment are safe and highly effective. Few studies described the sustained virologic response rates of treatment conducted by non-specialists. We performed a systematic review and meta‐analysis to evaluate the effectiveness of decentralized strategies of HCV treatment with DAAs. PubMed, Embase, Scopus and LILACS were searched until March-2019. Studies were screened by two researchers according to the following inclusion criteria: HCV treatment using DAAs on real-life cohort studies or clinical trials conducted by non-specialized health personnel. The primary endpoint was the sustained virologic response rate at week 12 after the end-of-treatment (SVR12), which is binary at the patient level. Data were extracted in duplicate using electronic-forms and quality appraisal was performed with the NIH Quality Assessment Tool. Heterogeneity was assessed by I² statistics. Random-effects meta-analysis models were used for pooling SVR12 rates. Publication bias was assessed using funnel plots. Among the 130 selected studies, nine papers were included for quantitative synthesis. The quality-appraisal was good for two, fair for three and poor for four studies. The pooled relative risk (RR) of SVR12 was not statistically different between decentralized strategy and treatment by specialists [RR = 1.05; 95% confidence interval (95% CI): 0.98–1.1; I² = 45% (95% CI: 0–84%), p = 0.145]. SVR12 rate for decentralized HCV treatment was 81% [SVR12 95% CI: 72–89%; I² = 93% (95% CI: 88–96%)] and 95% [SVR12 95%CI: 92–98%; I² = 77% (95% CI: 52–89%)] with intention to treat analysis and per-protocol analysis, respectively. SVR12 rates using DAAs managed by non-specialized health personnel were satisfactory and similar to those obtained by specialists. This new delivery strategy can improve access to HCV treatment, especially in resource-limited settings. PROSPERO #: CRD42019122609.

Effectiveness of generic direct-acting agents for the treatment of hepatitis C: systematic review and meta-analysis

Objective

To compare the efficacy of generic direct-acting agents and brand-name medicines for treating hepatitis C virus (HCV) infection by conducting a systematic review and meta-analysis.

Methods

We searched online databases for studies that reported sustained virological responses 12 weeks after the end of HCV treatment with generic direct-acting agents. We derived pooled proportions of treated patients with a sustained virological response from intention-to-treat and per-protocol analyses. In addition, we calculated the pooled relative risk (RR) of a sustained virological response brand-name versus generic direct-acting agents using a random-effects model (DerSimonian-Laird) from the data available. Between-study heterogeneity was assessed using the I² statistic.

Findings

We identified 19 studies involving a total of 57 433 individuals from eight territories or regions. The pooled overall proportions of patients with a sustained virological response were 98% (95% confidence interval, CI: 97-99; 18 studies; I²  = 94.1%) in per-protocol analyses and 96% (95% CI: 93-98; 8 studies; I²  = 68.1%) in intention-to-treat analyses. The likelihood of a sustained virological response with brand-name medicines was similar to that with generic direct-acting agents (RR: 1.00; 95% CI: 0.98-1.02; I²  = 0.0%). The likelihood of a sustained virological response was significantly higher in patients without than with cirrhosis (RR:1.03; 95% CI: 1.01-1.06; 7 studies) but was not significantly affected by either previous treatment (3 studies) or human immunodeficiency virus coinfection (3 studies).

Conclusion

Generic direct-acting agents are highly effective for treating hepatitis C. Generic agents should be considered in resource-constrained settings for decreasing the burden of liver disease in HCV-infected patients.

B.A.R.C.O.S. (Brazilian Argentine Hepatitis C Collaborative Observational Study): Effectiveness and clinical outcomes of HCV treatment with daclatasvir and sofosbuvir with or without ribavirin

Real-world data evaluating the effectiveness of direct-acting antivirals (DAAs) in hepatitis C virus (HCV) treatment have been reported from different regions. Our aim was to evaluate the effectiveness and clinical outcomes of daclatasvir (DCV) and sofosbuvir (SOF) ± ribavirin (RBV) in a prospective multicentre cohort study including patients from Argentina and Brazil who received DCV/SOF ± RBV for 12 or 24 weeks from 2015 to 2018. Multivariable logistic regression models were carried out to identify factors associated with failure to achieve sustained virologic response (SVR) as a primary end point, and to death, decompensation, hepatocellular carcinoma (HCC) or liver transplantation (LT) as a composite secondary end point. From a total of 1517 patients treated with DCV/SOF, 906 completed 12 weeks post-treatment evaluation and were included in the analysis. Overall SVR12 rate was 96.1% (95% CI: 94.6%-97.2%), and 95% (95% CI: 92.8%-96.6%) in patients with cirrhosis. LT recipients and presence of cirrhosis were independently associated with failure to achieve SVR. During post-SVR12 follow-up, cumulative incidence of the secondary end point was 2.4% (95% CI: 1.5%-3.6%); two patients died from nonliver-related causes and two from HCC, five underwent LT, 12 developed HCC and 17 patients developed hepatic decompensation. Independent variables associated with these composite secondary end points were prior to HCV treatment and presence of cirrhosis. In conclusion, although the high pangenotypic effectiveness of DCV/SOF ± RBV was confirmed in our real-life cohort, patients with compensated and decompensated cirrhosis showed higher risk of non-SVR and complication appearance during treatment or after achieving SVR.

Status of Direct-Acting Antiviral Therapy for Hepatitis C Virus Infection and Remaining Challenges

Chronic infection with hepatitis C virus is a major cause of liver disease and hepatocellular carcinoma worldwide. After the discovery of hepatitis C virus 3 decades ago, the identification of the structure of the viral proteins, combined with high-throughput replicon models, enabled the discovery and development of direct-acting antivirals. These agents have revolutionized patient care, with cure rates of more than 90%. We review the status of direct-acting antiviral therapies for hepatitis C virus infection and discuss remaining challenges. We highlight licensed compounds, discuss the potential to shorten therapy even further, and review different options for treatment failure and resistance. We also provide an overview of clinical experience with generic agents and evidence for their efficacy. Finally, we discuss the need for new drugs and outline promising targets for future therapies.

Generic sofosbuvir-based interferon-free direct acting antiviral agents for patients with chronic hepatitis C virus infection: a real-world multicenter observational study

Real-world data regarding the effectiveness and safety of generic sofosbuvir (SOF)-based interferon-free direct acting antiviral agents (DAAs) for patients with chronic hepatitis C virus (HCV) infection remain limited. A total of 517 chronic HCV-infected patients receiving 12 or 24 weeks of SOF-based therapies were retrospectively enrolled in 4 academic centers in Taiwan. The rate of sustained virologic response at week 12 off-therapy (SVR₁₂) and that of treatment completion were assessed. The baseline characteristics and on-treatment HCV viral kinetics to predict SVR₁₂ were analyzed. By evaluable population (EP) analysis, the SVR₁₂ rate was 95.4% (95% confidence interval [CI]: 93.2–96.9%). The SVR₁₂ was achieved in 29 of 34 patients (85.3%, 95% CI: 69.6–93.6%), 130 of 139 patients (93.5%, 95% CI: 88.2–96.6%), 119 of 124 patients (96.0%, 95% CI: 90.9–98.3%) and 215 of 220 patients (97.7%, 95% CI: 94.8–99.0%) who received SOF in combination with ribavirin (RBV), ledipasvir (LDV), daclatasvir (DCV) and velpatasvir (VEL), respectively. Of 517 patients, 514 (99.4%) completed the scheduled treatment. All 15 patients with true virologic failures were relapsers. Two decompensated cirrhotic patients had on-treatment deaths which were not related to DAAs. All 7 patients who were lost to follow-up had undetectable HCV RNA level at the last visit. The SVR₁₂ rates were comparable in terms of baseline patient characteristics and viral decline at week 4 of treatment. In conclusion, generic SOF-based regimens are well tolerated and provide high SVR₁₂ rates in patients with chronic HCV infection.

High efficacy of generic and brand direct acting antivirals in treatment of chronic hepatitis C

BACKGROUND

Direct acting antivirals (DAAs) are highly effective for treatment of hepatitis C (HCV) but brand products are priced beyond the means of most low and middle income countries (LMICs). Although a few DAAs are offered at reduced prices in access programs, they are still beyond affordability in limited resource settings with a large HCV infected population. Cheap generics might fill this economic need, but studies comparing their clinical efficacy to that of original products are limited.

AIM

To compare efficacy of brand and generic DAAs used in the national treatment program in Egypt.

METHODS

HCV treatment eligible patients (n=971) were enrolled. They were treated with 12 weeks of either sofosbuvir-daclatasvir (SOF-DCV) or SOF-ledipasvir (SOF-LDV). Ribavirin (RBV) was added to patients with cirrhosis and to SOF experienced patients. Patients with cirrhosis who were RBV intolerant were treated for 24 weeks without RBV.

RESULTS

Most patients were males (61.4%), treatment naïve (88.6%), without cirrhosis (61.7%), and the mean age was 51.3±11.31 years. Baseline characteristics were not different in patients treated with brand or generic medications regarding age, liver tests, creatinine, platelets, MELD score, baseline HCV-RNA and transient elastography. Overall sustained virologic response (SVR) rate was 98.1%, which was similar for generic and brand drugs (98.2% vs. 98.1%; p=1), and similar with both regimens used (SOF-DCV±RBV: brand: 98.1%, generic 97.8%; p=0.729, SOF-LDV±RBV: brand 98.2%, generic 100%; p=0.729). AST and ALT decreased significantly with initiation of therapy with both generic and original drugs.

CONCLUSION

Generic and brand DAAs are equally effective for achieving SVR and improving aminotransferases.

Generic velpatasvir plus sofosbuvir for hepatitis C virus infection in patients with or without human immunodeficiency virus coinfection

BACKGROUND

Data are limited regarding the effectiveness and safety of generic velpatasvir plus sofosbuvir (VEL/SOF) for hepatitis C virus (HCV) in patients with or without human immunodeficiency virus (HIV) coinfection.

AIM

To evaluate the effectiveness and safety of generic VEL/SOF-based therapy for HCV infection in patients with or without HIV coinfection in Taiwan.

METHODS

Sixty-nine HIV/HCV-coinfected and 159 HCV-monoinfected patients receiving 12 weeks of generic VEL/SOF with or without ribavirin (RBV) for HCV were prospectively enrolled. The anti-viral responses and the adverse events (AEs) were compared between the two groups. The characteristics potentially related to sustained virological response 12 weeks off therapy (SVR₁₂ ) were analysed.

RESULTS

The SVR₁₂ was achieved in 67 HIV/HCV-coinfected patients (97.1%; 95% CI: 90.0%-99.2%) and in 156 HCV-monoinfected patients (98.1%; 95% CI: 94.6%-99.4%) receiving VEL/SOF-based therapy, respectively. The SVR₁₂ rates were comparable between HIV/HCV-coinfected and HCV-monoinfected patients, regardless of pre-specified baseline characteristics. One hundred twenty-two (53.5%) and seven (3.1%) patients had baseline resistance-associated substitutions (RASs) in HCV NS5A and NS5B regions, but the SVR₁₂ rates were not affected by the presence or absence of RASs. One (1.4%) and five (3.1%) patients in the HIV/HCV-coinfected and HCV-monoinfected groups had serious AEs. No patient died or discontinued treatment due to AEs. The eGFR remained stable throughout the course of treatment in HIV/HCV-coinfected patients receiving anti-retroviral therapy containing tenofovir disoproxil fumarate (TDF).

CONCLUSIONS

Generic VEL/SOF-based therapy is well-tolerated and provides comparably high SVR₁₂ rates for HCV infection in patients with and without HIV coinfection.
