J Clin Med 2024; 13:2939. [PMID: 38792479 PMCID: PMC11121813 DOI: 10.3390/jcm13102939] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2024] [Revised: 05/10/2024] [Accepted: 05/14/2024] [Indexed: 05/26/2024] Open
Abstract
Background: Chronic hepatitis C (HCV) infection presents global health challenges with significant morbidity and mortality implications. Successfully treating patients with cirrhosis may lead to mortality rates comparable to the general population. This study aims to utilize machine learning techniques to create predictive mortality models for individuals with chronic HCV infections. Methods: Data from chronic HCV patients at Sultan Qaboos University Hospital (2009-2017) underwent analysis. Data pre-processing handled missing values and scaled features using Python via Anaconda. Model training involved SelectKBest feature selection and algorithms such as logistic regression, random forest, gradient boosting, and SVM. The evaluation included diverse metrics, with 5-fold cross-validation, ensuring consistent performance assessment. Results: A cohort of 702 patients meeting the eligibility criteria, predominantly male, with a median age of 47, was analyzed across a follow-up period of 97.4 months. Survival probabilities at 12, 36, and 120 months were 90.0%, 84.0%, and 73.0%, respectively. Ten key features selected for mortality prediction included hemoglobin levels, alanine aminotransferase, comorbidities, HCV genotype, coinfections, follow-up duration, and treatment response. Machine learning models, including the logistic regression, random forest, gradient boosting, and support vector machine models, showed high discriminatory power, with logistic regression consistently achieving an AUC value of 0.929. Factors associated with increased mortality risk included cardiovascular diseases, coinfections, and failure to achieve a SVR, while lower ALT levels and specific HCV genotypes were linked to better survival outcomes. Conclusions: This study presents the use of machine learning models to predict mortality in chronic HCV patients, providing crucial insights for risk assessment and tailored treatments. Further validation and refinement of these models are essential to enhance their clinical utility, optimize patient care, and improve outcomes for individuals with chronic HCV infections.

Abstract
Hepatitis C virus (HCV) infection is common in the United States and leads to significant morbidity, mortality, and economic costs. Simplified screening recommendations and highly effective direct-acting antivirals for HCV present an opportunity to eliminate HCV. The objective of this study was to increase testing, linkage to care, treatment, and cure of HCV. This was an observational, prospective, population-based intervention program carried out between September 2014 and September 2018 and performed in three community health centers, three large multiclinic health care systems, and an HCV patient education and advocacy group in King County, WA. There were 232,214 patients included based on criteria of documented HCV-related diagnosis code, positive HCV laboratory test or prescription of HCV medication, and seen at least once at a participating clinical site in the prior year. Electronic health record (EHR) prompts and reports were created. Case management linked patients to care. Primary care providers received training through classroom didactics, an online curriculum, specialty clinic shadowing, and a telemedicine program. The proportion of baby boomer patients with documentation of HCV testing increased from 18% to 54% during the project period. Of 77,577 baby boomer patients screened at 87 partner clinics, 2,401 (3%) were newly identified HCV antibody positive. The number of patients staged for treatment increased by 391%, and those treated increased by 1,263%. Among the 79% of patients tested after treatment, 95% achieved sustained virologic response. Conclusion: A combination of EHR-based health care system interventions, active linkage to care, and clinician training contributed to a tripling in the number of patients screened and a more than 10-fold increase of those treated. The interventions are scalable and foundational to the goal of HCV elimination.

Abstract
The management of hepatitis C virus (HCV) infections has changed dramatically in recent years with the use of direct antiviral agents (AADs). New AADs have excellent safety profile and demonstrated to be highly effective. Interferon free regimens are now recommended for children and adolescents but significant barriers for treatment exist. Overcoming those barriers will facilitate HCV elimination. This review covers varied topics to familiarize providers with the current status of pediatric HCV management in light of newly available DAAs medications.

[PMID: 32145260 DOI: 10.1016/j.jhep.2020.02.022] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2019] [Revised: 02/06/2020] [Accepted: 02/18/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND & AIMS Treating HCV infection reduces overall mortality and reduces the risk of multiple extrahepatic complications. Whether the reduction in mortality is primarily due to a reduction in liver-related causes or extrahepatic complications is unknown. METHODS We identified HCV-positive individuals treated for HCV, and propensity score-matched them to HCV-positive/untreated and HCV-uninfected individuals in ERCHIVES between 2002-2016. We extracted cause of death data from the National Center for Health Statistics' National Death Index. Viral hepatitis-associated liver-related mortality rates among treated and untreated HCV-infected persons were calculated by treatment and attainment of sustained virologic response (SVR). RESULTS Among 50,674 HCV-positive/treated (Group A), 31,749 HCV-positive/untreated (Group B) and 73,526 HCV-uninfected persons (Group C), 8.6% in Group A, 35.0% in Group B, and 14.3% in Group C died. Among those who died, viral hepatitis-associated liver-related mortality rates per 100 patient-years (95% CI) were: 0.28 (0.27-0.30) for Group A; 1.44 (1.38-1.49) for Group B; and 0.06 (0.05-0.06) for Group C; (p <0.0001 for both comparisons). Among HCV-positive/treated persons, rates were 0.06 (0.05-0.06) for those with SVR vs. 0.78 (0.74-0.83) for those without SVR. In competing risks Cox proportional hazards analysis, treatment with all-oral DAA regimens (adjusted hazard ratio 0.11; 95% CI 0.09-0.14) and SVR (adjusted hazard ratio 0.10; 95% CI 0.08-0.11) were associated with reduced hazards of liver-related mortality. CONCLUSIONS Treatment for HCV is associated with a significant reduction in viral hepatitis-associated liver-related mortality, which is particularly pronounced in those treated with DAA regimens and those who attain SVR. This may account for a significant proportion of the reduction in all-cause mortality reported in previous studies. LAY SUMMARY Treating hepatitis C virus (HCV) infection is known to reduce overall mortality. However, whether the reduction in mortality is primarily due to a reduction in liver-related causes or extrahepatic complications was previously unknown. Herein, we show that while treating HCV with direct-acting antiviral regimens has numerous extrahepatic benefits, a significant benefit can be attributed specifically to the reduction in liver-related mortality.

Abstract
OBJECTIVE To assess the impact of direct acting anti-viral (DAA) therapy for hepatitis C virus (HCV) infection on changes in pain intensity and prescription opioid use among Veterans. METHODS We conducted a retrospective cohort study of Veterans with HCV who were seen in a rheumatology clinic at least once while receiving DAA therapy between January 1, 2010 and December 31st 2016. Demographic characteristics, HCV status, HCV treatment characteristics, numeric rating scale (NRS) pain scores and opioid prescription data were extracted from the electronic medical record. Pain scores were averaged over 6 months prior to HCV treatment and 6 months after completion of treatment. Prescription opioid dose was converted to a morphine equivalent daily dose (MEDD) and averaged across the two 6-month intervals. Generalized estimating equations were used to model the change in average pain and MEDD from pre- to post-HCV treatment. Effect size was assessed using Cohen's d. RESULTS A total of 121 Veterans, 91% male with average age of 59 were included. Average pre-treatment pain was 4.4 (SD 2.4). The average reduction in pain scores was 0.6 points (P = 0.02, Cohen's d = 0.22) after treatment. Among 67 patients prescribed chronic opioid therapy at baseline, average pre-treatment MEDD was 52.4 mg (SD = 62.5 mg) and post-DAA treatment average MEDD was 49.5 mg (SD = 69.3 mg), representing a decrease by 2.9 mg (P < 0.01, Cohen's d = 0.14). Opioid dose reduction was seen in 43/67 patients and 12 patients discontinued opioids entirely. CONCLUSION Among US Veterans, subjective pain scores had modest improvement and opioid prescriptions were mildly reduced following treatment with DAA.

Abstract
Background The association between liver stiffness measurements (LSM) and mortality has not been fully described. In particular the effect of LSM on all-cause mortality taking sustained virological response (SVR) into account needs further study. Methods HIV/HCV participants in the French nation-wide, prospective, multicenter ANRS CO13 HEPAVIH cohort, with ≥1 LSM by FibroScan (FS) and a detectable HCV RNA when the first valid FS was performed were included. Cox proportional hazards models with delayed entry were performed to determine factors associated with all-cause mortality. LSM and SVR were considered as time dependent covariates. Results 1,062 patients were included from 2005 to 2015 (69.8% men, median age 45.7 years (IQR 42.4–49.1)). 21.7% had baseline LSM >12.5 kPa. Median follow-up was 4.9 years (IQR 3.2–6.1). 727 (68.5%) were ever treated for HCV: 189 of them (26.0%) achieved SVR. 76 deaths were observed (26 liver-related, 10 HIV-related, 29 non-liver-non-HIV-related, 11 of unknown cause). At the age of 50, the mortality rate was 4.5% for patients with LSM ≤12.5 kPa and 10.8% for patients with LSM >12.5 kPa. LSM >12.5 kPa (adjusted Hazard Ratio [aHR] = 3.35 [2.06; 5.45], p<0.0001), history of HCV treatment (aHR = 0.53 [0.32; 0.90], p = 0.01) and smoking (past (aHR = 5.69 [1.56; 20.78]) and current (3.22 [0.93; 11.09]) versus never, p = 0.01) were associated with all-cause mortality independently of SVR, age, sex, alcohol use and metabolic disorders. Conclusion Any LSM >12.5 kPa was strongly associated with all-cause mortality independently of SVR and other important covariates. Our results suggest that close follow-up of these patients should remain a priority even after achieving SVR.

Abstract
BACKGROUND Direct-acting antiviral (DAA) drugs have been highly effective in the treatment of chronic hepatitis C (HCV) infection. Limited data exist comparing the safety, tolerability, and efficacy of DAAs in African-American (AA) patients with chronic hepatitis C genotype 1 (HCV GT-1) in the community practice setting. We aim to evaluate treatment response of DAAs in these patients. PATIENTS AND METHODS All the HCV GT-1 patients treated with DAAs between January 2014 and January 2018 in a community clinic setting were retrospectively analyzed. Pretreatment baseline patient characteristics, treatment efficacy with a sustained virologic response at 12 weeks post-treatment (SVR12), and adverse reactions were assessed. RESULTS Two-hundred seventy-eight patients of AA descent were included in the study. One-hundred sixty-two patients were treated with ledipasvir/sofosbuvir (SOF)±ribavirin, 38 were treated with simeprevir/SOF±ribavirin, and 38 patients were treated with SOF/velpatasvir. Overall, SVR at 12 weeks was achieved in 94.6% in patients who received one of the three DAA regimens (93.8% in ledipasvir/SOF group, 92.1% in simeprevir/SOF group, and 97.4% in SOF/velpatasvir group). Previous treatment experience, HCV RNA levels and HIV status had no statistical significance on overall SVR achievement (P=0.905, 0.680, and 0.425, respectively). Compensated cirrhosis in each of the treatment groups did not influence overall SVR of 12. The most common adverse effect was fatigue (27%). None of the patients discontinued the treatment because of adverse events. CONCLUSION In the real-world setting, DAAs are safe, effective, and well tolerated in African-American patients with chronic HCV GT-1 infection with a high overall SVR rate of 94.6%. Treatment rates did not differ on the basis of previous treatment and compensated cirrhosis status.

Abstract
BACKGROUND Chronic kidney disease (CKD) was a relative contraindication to hepatitis C virus (HCV) treatment in the interferon/ribavirin era. AIM To determine the efficacy, tolerability and safety of sofosbuvir/ledipasvir (SOF/LDV) and paritaprevir/ritonavir/ombitasvir/dasabuvir (PrOD) regimens in persons with CKD. METHODS We identified persons initiated on a SOF/LDV or PrOD regimen from October 30, 2014 to April 30, 2016. We excluded those with missing HCV genotype or eGFR values. We determined treatment completion and sustained virologic response (SVR) rates, and proportion developing worsening renal function or grade 3/4 haematologic toxicity. RESULTS Among 13 663 persons on SOF/LDV±ribavirin, 14% and 1% persons had CKD Stage 3 and 4-5 respectively, 67.8% completed treatment, 98.2% achieved SVR. Treatment completion or SVR rates did not decline with advanced CKD or ribavirin administration. Among 3961 persons on PrOD±ribavirin, 9% and 3% persons had CKD Stage 3 and 4-5, respectively, 74.0% completed treatment and 98.2% achieved SVR. A decrease in treatment completion rates was seen in CKD stage 4-5 and those on ribavirin, but this did not impact SVR rates. A >10 mL/min/1.73 m2 drop in eGFR from baseline was observed in 30%-38% of persons with baseline eGFR ≥60 mL/min/1.73 m2 , but in only 0%-6% with CKD4-5. Grade 3/4 anaemia was more frequent in persons with CKD4-5, but ribavirin co-administration did not appear to affect this. CONCLUSIONS SOF/LDV and PrOD achieved high SVR rates in CKD population. Treatment completion rates were lower than expected. A decline in eGFR and development of anaemia were observed in a substantial proportion of persons, but the clinical implications remain unclear.

Abstract
Recent preclinical studies have suggested an antifibrotic role for tricyclic antidepressants (TCA). Using the Electronically Retrieved Cohort of hepatitis C virus (HCV) Infected Veterans, we aimed to evaluate the impact of TCA use on fibrosis progression and development of hepatocellular carcinoma (HCC) among HCV-infected persons. Subjects were categorized according to use of TCAs, selective serotonin reuptake inhibitors (SSRI) or no antidepressants. TCAs or selective serotonin uptake inhibitors use was defined according to cumulative defined daily dose (cDDD), and categories were mutually exclusive. Subjects with HIV coinfection, hepatitis B surface antigen (HbsAg) positivity, cirrhosis or HCC at baseline were excluded. Outcomes were liver fibrosis progression measured by APRI scores and incident HCC. We utilized Cox proportional hazards regression to determine predictors of cirrhosis, defined as APRI > 2, and incident hepatocellular carcinoma (iHCC). Among 128 201 eligible HCV+ persons, 4% received TCAs, 43% received selective serotonin uptake inhibitors, and 53% received no antidepressants. Fewer TCAs users had drug abuse (34% and 43%) and alcohol abuse (32% vs 42%) compared to selective serotonin uptake inhibitor users. After adjusting for age, baseline APRI score, diabetes, hypertension, alcohol use, drug abuse and HCV RNA levels, TCAs use was associated with decreased risk of cirrhosis (hazard ratio [HR] = 0.77, 95% CI = 0.60, 0.99) and delayed time to development of cirrhosis, but not with decreased iHCC. In conclusion among a large cohort of HCV-positive Veterans, TCAs use was associated with decreased fibrosis progression and lower risk of developing cirrhosis. These data provide supportive evidence for the beneficial effects of TCAs on progression of liver fibrosis in patients with chronic HCV infection.

Race affects SVR12 in a large and ethnically diverse hepatitis C-infected patient population following treatment with direct-acting antivirals: Analysis of a single-center Department of Veterans Affairs cohort. Pharmacol Res Perspect 2018; 6:e00379. [PMID: 29484189 PMCID: PMC5821896 DOI: 10.1002/prp2.379] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2017] [Accepted: 11/16/2017] [Indexed: 12/13/2022] Open
Abstract
Hepatitis C virus (HCV) infection is a major cause of chronic liver disease. HCV cure has been linked to improved patient outcomes. In the era of direct-acting antivirals (DAAs), HCV cure has become the goal, as defined by sustained virological response 12 weeks (SVR12) after completion of therapy. Historically, African-Americans have had lower SVR12 rates compared to White people in the interferon era, which had been attributed to the high prevalence of non-CC interleukin 28B (IL28B) type. Less is known about the association between race/ethnicity and SVR12 in DAA-treated era. The aim of the study is to evaluate the predictors of SVR12 in a diverse, single-center Veterans Affairs population. We conducted a retrospective study of patients undergoing HCV therapy with DAAs from 2014 to 2016 at the VA Greater Los Angeles Healthcare System. We performed a multivariable logistic regression analysis to determine predictors of SVR12, adjusting for age, HCV genotype, DAA regimen and duration, human immunodeficiency virus (HIV) status, fibrosis, nonalcoholic fatty liver disease (NAFLD) fibrosis score, homelessness, mental health, and adherence. Our cohort included 1068 patients, out of which 401 (37.5%) were White people and 400 (37.5%) were African-American. Genotype 1 was the most common genotype (83.9%, N = 896). In the adjusted models, race/ethnicity and the presence of fibrosis were statistically significant predictors of non-SVR. African-Americans had 57% lower odds for reaching SVR12 (adj.OR = 0.43, 95% CI = 1.5-4.1) compared to White people. Advanced fibrosis (adj.OR = 0.40, 95% CI = 0.26-0.68) was also a significant predictor of non-SVR. In a single-center VA population on DAAs, African-Americans were less likely than White people to reach SVR12 when adjusting for covariates.

Abstract
Background Interferon-based regimens are associated with a substantial survival benefit for persons infected with hepatitis C virus (HCV). Survival data with direct-acting antiviral agents are not available. We conducted this study to quantify the effect of paritaprevir/ritonavir, ombitasvir, dasabuvir (PrOD) and ledipasvir/sofosbuvir (LDV/SOF) regimens upon mortality. Methods In the Electronically Retrieved Cohort of HCV Infected Veterans (ERCHIVES), a well-established national cohort of HCV-infected Veterans, we identified HCV-infected persons initiated on PrOD or LDV/SOF, excluding those with human immunodeficiency virus, hepatitis B surface antigen positivity, hepatocellular carcinoma, or missing HCV RNA or FIB-4 scores. For each case, we identified a propensity score-matched control never initiated on treatment. Primary outcome was survival. Outcomes were assessed using frequency of events, Kaplan-Meier curves, and Cox proportional hazards regression analyses. Results We identified 1473 persons on PrOD, 5497 on LDV/SOF, and 6970 propensity score-matched untreated persons. Treated persons were more likely to be obese and have cirrhosis, but less likely to have stage 3-5 chronic kidney disease (CKD), alcohol or drug abuse or dependence diagnosis, and anemia. The proportion of persons who died was higher in the untreated group compared with either treatment group (PrOD, 0.3%; LDV/SOF, 1.4%; untreated controls, 2.5%; P < .001). A significantly larger percentage of treated patients survived to 18 months of follow-up, compared with untreated controls (P < .001). In multivariable Cox regression analysis, treatment with either regimen (hazard ratio [HR], 0.43; 95% confidence interval [CI], .33-.57) and attainment of sustained virologic response (SVR) were associated with significantly lower mortality (HR, 0.57; 95% CI, .33-.99). Conclusions Treatment with PrOD or LDV/SOF and SVR are associated with a significant mortality benefit, apparent within the first 18 months of treatment.

Abstract
AIM To define predictors of functional benefit of direct-acting antivirals (DAAs) in patients with chronic hepatitis C virus (HCV) infection and liver cirrhosis.
METHODS We analysed a cohort of 199 patients with chronic HCV genotype 1, 2, 3 and 4 infection involving previously treated and untreated patients with compensated (76%) and decompensated (24%) liver cirrhosis at two tertiary centres in Germany. Patients were included with treatment initiation between February 2014 and August 2016. All patients received a combination regimen of one or more DAAs for either 12 or 24 wk. Predictors of functional benefit were assessed in a univariable as well as multivariable model by binary logistic regression analysis.
RESULTS Viral clearance was achieved in 88% (175/199) of patients. Sustained virological response (SVR) 12 rates were as follows: among 156 patients with genotype 1 infection the SVR 12 rate was 90% (n = 141); among 7 patients with genotype 2 infection the SVR 12 rate was 57% (n = 4); among 30 patients with genotype 3 infection the SVR 12 rate was 87% (n = 26); and among 6 patients with genotype 4 infection the SVR 12 rate was 67% (n = 4). Follow-up MELD scores were available for 179 patients. A MELD score improvement was observed in 37% (65/179) of patients, no change of MELD score in 41% (74/179) of patients, and an aggravation was observed in 22% (40/179) of patients. We analysed predictors of functional benefit from antiviral therapy in our patients beyond viral eradication. We identified the Child-Pugh score, the MELD score, the number of platelets and the levels of albumin and bilirubin as significant factors for functional benefit.
CONCLUSION Our data may contribute to the discussion of potential risks and benefits of antiviral therapy with individual patients infected with HCV and with advanced liver disease.

Abstract
Background Low serum vitamin D levels in chronic hepatitis C (CHC) is associated with advanced liver fibrosis; and there remains an imprecise relationship with the treatment response based on the vitamin D levels. Previous studies have shown conflicting results on the vitamin D levels, and association with treatment response in CHC treated with interferon-based regimens. Methods Patients with CHC treated with direct-acting antivirals (DAAs) between January 2016 and December 2017 in the community clinic setting were retrospectively analyzed. Pretreatment baseline patient characteristics, treatment efficacy with the sustained virologic response at 12 weeks post-treatment (SVR 12) were assessed in CHC patients with deficient, insufficient, and normal levels of vitamin D measured before the initiation of DAA therapy. Results Two hundred and ninety-one patients were included in the study. Direct-acting antivirals included in the study were ledipasvir/sofosbuvir ± ribavirin, ombitasvir + paritaprevir + ritonavir + dasabuvir ± ribavirin, and sofosbuvir/velpatasvir. An overall sustained virologic response was achieved in 95% (n = 276) of patients. SVR 12 rates among patients with vitamin D deficiency, vitamin D insufficiency and normal vitamin D levels were 92%, 96.2%, and 97.2% respectively and was not statically significant (P = 0.214). A total of 71 patients were cirrhotic. The prevalence of vitamin D insufficiency (20 - 29.9 ng/mL) and deficiency (< 20 ng/mL) was significantly higher in cirrhotic patients (P = 0.01). Despite this, pretreatment vitamin D levels did not show any impact on the virologic response. The most common adverse effect observed was fatigue. None of the patients had to discontinue the treatment due to adverse events. Conclusions DAAs are safe and effective with a high overall SVR 12 in CHC and treatment response does not depend on the pretreatment vitamin D levels. The prevalence of both vitamin D insufficiency and deficiency was observed to be higher in cirrhotic cohorts compared to non-cirrhotic counterparts.

Abstract
Solid tumors are much more common than hematologic malignancies. Although severe and prolonged neutropenia is uncommon, several factors increase the risk of infection in patients with solid tumors, and the presence of multiple risk factors in the same patient is not uncommon. These include obstruction (most often caused by progression of the tumor), disruption of natural anatomic barriers such as the skin and mucosal surfaces, and treatment-related factors such as chemotherapy, radiation, diagnostic and/or therapeutic surgical procedures, and the increasing use of medical devices such as various catheters, stents, and prostheses. Common sites of infection include the skin and skin structures (including surgical site infections), the bloodstream (including infections associated with central venous catheters), the lungs, the hepato-biliary and intestinal tracts, and the urinary tract, and include distinct clinical syndromes such as post-obstructive pneumonia, obstructive uropathy, and neutropenic enterocolitis. The epidemiology of most of these infections is changing with resistant organisms [MRSA, Pseudomonas aeruginosa, extended spectrum beta-lactamase (ESBL)-producing organisms] being isolated more often than in the past. Polymicrobial infections now predominate when deep tissue sites are involved. Conservative management of most of these infections (antibiotics, fluid and electrolyte replacement, bowel rest when needed) is generally effective, with surgical intervention being reserved for the drainage of deep abscesses, or to deal with complications such as intestinal obstruction or hemorrhage. Infected prostheses often need to be removed. Reactivation of certain viral infections (HBV, HCV, and occasionally CMV) has become an important issue, and screening, prevention and treatment strategies are being developed. Infection prevention, infection control, and antimicrobial stewardship are important strategies in the overall management of infections in patients with solid tumors. Occasionally, infections mimic solid tumors and cause diagnostic and therapeutic challenges.

Abstract
Abstract
Background:
The high cost of new hepatitis C (HCV) treatments has resulted in “watchful waiting” strategies being developed to safely delay treatment, which will in turn delay viral load suppression (VLS).
Objective:
To document if delayed VLS adversely impacted patient risk for adverse events and death.
Methods:
187,860 patients were selected from the Veterans Administration’s (VA) clinical registry (CCR), a longitudinal compilation of electronic medical records (EMR) data for 1999–2010. Inclusion criteria required at least 6 months of CCR/EMR data prior to their HCV diagnosis and sufficient data post-diagnosis to calculate one or more FIB-4 scores. Primary outcome measures were time-to-death and time-to-a composite of liver-related clinical events. Cox proportional hazards models were estimated separately using three critical FIB-4 levels to define early and late viral response.
Results:
Achieving an undetectable viral load before the patient’s FIB-4 level exceed pre-specified critical values (1.00, 1.45 and 3.25) effectively reduced the risk of an adverse clinical events by 33–35% and death by 21–26%. However, achieving VLS after FIB-4 exceeds 3.25 significantly reduced the benefit of viral response.
Conclusions:
Delaying VLS until FIB-4 >3.25 reduces the benefits of VLS in reducing patient risk.

Abstract
BACKGROUND Ribavirin is a key component of several hepatitis C virus (HCV) treatment regimens. However, its utility in combination with newer directly acting anti-viral agents regimens is unclear. AIM To determine the SVR rates with paritaprevir/ritonavir/ombitasvir/dasabuvir (PrOD) regimen ± ribavirin and compare this with sofosbuvir/simeprevir and sofosbuvir/ledipasvir regimens. METHODS We used Electronically Retrieved Cohort of HCV Infected Veterans (ERCHIVES), a well-established national cohort of HCV-infected Veterans to identify HCV genotype 1 infected persons initiated on the above regimens. We excluded those with HIV coinfection, positive HBsAg and missing HCV RNA. RESULTS We identified 1235 persons on PrOD (75.5% ribavirin), 1254 on sofosbuvir/simeprevir (16.9% ribavirin) and 4247 on sofosbuvir/ledipasvir (23.3% ribavirin). Among HCV genotype 1a infected persons, ribavirin was prescribed to 99.2% on PrOD, 18.2% on sofosbuvir/simeprevir and 23.3% on sofosbuvir/ledipasvir. The SVR rates ranged from 92.6% to 100% regardless of the treatment regimen, presence of cirrhosis or HCV subtype, except in PrOD group without ribavirin, HCV genotype 1a without cirrhosis (SVR 80%, N = 5). There were minor, clinically insignificant differences in SVR rates in those treated with or without ribavirin in each of the treatment groups, regardless of presence of cirrhosis at baseline. In multivariable logistic regression analysis, ribavirin use was not associated with achieving SVR in any group. CONCLUSIONS In HCV genotype 1 infected persons, PrOD, sofosbuvir/simeprevir and sofosbuvir/ledipasvir regimens, are associated with high rates of SVR in actual clinical settings, which are comparable to clinical trials results (except PrOD genotype 1a with cirrhosis where the number was too small). The benefit of adding ribavirin to these regimens in the ERCHIVES treated cohort is not established.

Abstract
BACKGROUND & AIMS Role of non-adherence upon virological success with newer oral regimens is unknown. We sought to determine the impact of treatment adherence upon virological outcomes in hepatitis C virus (HCV) infected persons on sofosbuvir (SOF)-based regimens, using pharmacy prescription data as a measure of adherence. METHODS We analysed HCV infected persons in Electronically Retrieved Cohort of HCV Infected Veterans, who were initiated on SOF-based regimens, excluding those with human immunodeficiency virus, positive hepatitis-B surface antigen, hepatocellular carcinoma and missing HCV RNA. RESULTS The final dataset included following regimens: SOF+simeprevir (SIM) (n = 1050), SOF+ledipasvir (LDV) (n = 974), SOF+ribavirin (RBV) (n = 663, genotype 2 or 3), and SOF+pegylated interferon (PEG)+RBV (n = 519, genotype 1 or 4). Those treated with a SOF-based regimen were older and more likely to have cirrhosis, diabetes, chronic kidney disease, higher HCV RNA levels, higher body mass index, compared with 1652 controls receiving a boceprevir-based (BOC) regimen. Sustained virological response (SVR12) rates for the SOF+SIM and SOF+LDV groups did not decline significantly even when as low as 50% of the full course was prescribed (except SOF+LDV, 90-99% prescriptions had SVR12 of 84.6%; n = 13). SOF+RBV for genotype 2/3 who received 50-80% of the prescriptions, 23/34 (67.6%) achieved SVR12. For persons with genotype 1/4 infection treated with SOF+PEG+RBV, no declines in SVR12 were seen with lower rates of prescriptions (40/43, or 93% SVR12 rate). CONCLUSIONS Sofosbuvir-based treatment regimens are highly effective in achieving SVR12. This efficacy is not significantly affected when treated persons receive less than a full prescribed course of treatment.

Improved Survival Among all Interferon-α-Treated Patients in HCV-002, a Veterans Affairs Hepatitis C Cohort of 2211 Patients, Despite Increased Cirrhosis Among Nonresponders. Dig Dis Sci 2016; 61:1744-56. [PMID: 27059981 PMCID: PMC5308124 DOI: 10.1007/s10620-016-4122-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2015] [Accepted: 03/06/2016] [Indexed: 02/06/2023]
Abstract
BACKGROUND As the era of interferon-alpha (IFN)-based therapy for hepatitis C ends, long-term treatment outcomes are now being evaluated. AIM To more fully understand the natural history of hepatitis C infection by following a multisite cohort of patients. METHODS Patients with chronic HCV were prospectively enrolled in 1999-2000 from 11 VA medical centers and followed through retrospective medical record review. RESULTS A total of 2211 patients were followed for an average of 8.5 years after enrollment. Thirty-one percent of patients received HCV antiviral therapy, 15 % with standard IFN/ribavirin only, 16 % with pegylated IFN/ribavirin, and 26.7 % of treated patients achieved sustained virologic response (SVR). Cirrhosis developed in 25.8 % of patients. Treatment nonresponders had a greater than twofold increase in the hazard of cirrhosis and hepatocellular carcinoma, compared to untreated patients, whereas SVR patients were only marginally protected from cirrhosis. Nearly 6 % developed hepatocellular carcinoma, and 27.1 % died during the follow-up period. Treated patients, regardless of response, had a significant survival benefit compared to untreated patients (HR 0.58, CI 0.46-0.72). Improved survival was also associated with college education, younger age, lower levels of alcohol consumption, and longer duration of medical service follow-up-factors typically associated with treatment eligibility. CONCLUSIONS As more hepatitis C patients are now being assessed for all-oral combination therapy, these results highlight that patient compliance and limiting harmful behaviors contribute a significant proportion of the survival benefit in treated patients and that the long-term clinical benefits of SVR may be less profound than previously reported.

Economic and Public Health Impacts of Policies Restricting Access to Hepatitis C Treatment for Medicaid Patients. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2016; 19:326-34. [PMID: 27325324 PMCID: PMC4916393 DOI: 10.1016/j.jval.2016.01.010] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/04/2015] [Revised: 01/24/2016] [Accepted: 01/27/2016] [Indexed: 05/27/2023]
Abstract
BACKGROUND Interferon-free hepatitis C treatment regimens are effective but very costly. The cost-effectiveness, budget, and public health impacts of current Medicaid treatment policies restricting treatment to patients with advanced disease remain unknown. OBJECTIVES To evaluate the cost-effectiveness of current Medicaid policies restricting hepatitis C treatment to patients with advanced disease compared with a strategy providing unrestricted access to hepatitis C treatment, assess the budget and public health impact of each strategy, and estimate the feasibility and long-term effects of increased access to treatment for patients with hepatitis C. METHODS Using a Markov model, we compared two strategies for 45- to 55-year-old Medicaid beneficiaries: 1) Current Practice-only advanced disease is treated before Medicare eligibility and 2) Full Access-both early-stage and advanced disease are treated before Medicare eligibility. Patients could develop progressive fibrosis, cirrhosis, or hepatocellular carcinoma, undergo transplantation, or die each year. Morbidity was reduced after successful treatment. We calculated the incremental cost-effectiveness ratio and compared the costs and public health effects of each strategy from the perspective of Medicare alone as well as the Centers for Medicare & Medicaid Services perspective. We varied model inputs in one-way and probabilistic sensitivity analyses. RESULTS Full Access was less costly and more effective than Current Practice for all cohorts and perspectives, with differences in cost ranging from $5,369 to $11,960 and in effectiveness from 0.82 to 3.01 quality-adjusted life-years. In a probabilistic sensitivity analysis, Full Access was cost saving in 93% of model iterations. Compared with Current Practice, Full Access averted 5,994 hepatocellular carcinoma cases and 121 liver transplants per 100,000 patients. CONCLUSIONS Current Medicaid policies restricting hepatitis C treatment to patients with advanced disease are more costly and less effective than unrestricted, full-access strategies. Collaboration between state and federal payers may be needed to realize the full public health impact of recent innovations in hepatitis C treatment.

Abstract
BACKGROUND & AIMS Sofosbuvir is widely prescribed for treatment of HCV infection. We compared the sustained virologic response rates (SVR12) and the haematologic toxicity of various sofosbuvir-based regimens in routine clinical practice. METHODS We used ERCHIVES (Electronically Retrieved Cohort of HCV infected Veterans) to identify HCV-infected persons initiated on sofosbuvir-based regimens. Treatment duration and regimen were defined as per labelling guidelines. We excluded persons with HIV, positive hepatitis-B surface antigen, hepatocellular carcinoma and missing HCV RNA. RESULTS Among 4257 sofosbuvir-treated persons, sofosbuvir/simeprevir (30%), sofosbuvir/ledipasvir (29%) and sofosbuvir/ribavirin (23%) were the most common combinations prescribed. The mean age (SD) was 60.22 (6.3) years, 96% were male, 22.4% were black, 37.2% had cirrhosis, 29.7% were treatment-experienced; baseline mean HCV RNA was 6.73 log lIU/ml. Comorbidities included: 40.2% alcohol abuse or dependence, 39.7% drug abuse or dependence, 25.1% diabetes and 14.4% stage 3-5 chronic kidney disease. Overall, 86.7% completed a full course of treatment. Overall, SVR12 rates were 88-98% in the sofosbuvir/simeprevir group and 93-98% in the sofosbuvir/ledipasvir group and did not vary based on previous treatment history or cirrhosis at baseline. For genotype 2/3 patients treated with sofosbuvir/ribavirin, SVR12 rates ranged from 69 to 87% with lowest rates in treatment-experienced cirrhotics. For the sofosbuvir/simeprevir and sofosbuvir/ledipasvir groups, grade3/4 haematologic adverse events were uncommon; these trended back close to baseline values after completion of treatment. CONCLUSIONS Sofosbuvir-based regimens in clinical practice are associated with SVR rates comparable to those seen in clinical trials and low rates of grade 3/4 haematological adverse events.

Abstract
BACKGROUND AND AIMS Supervised injection facilities (legally sanctioned spaces for supervised consumption of illicitly obtained drugs) are controversial public health interventions. We determined the optimal number of facilities in two Canadian cities using health economic methods. DESIGN Dynamic compartmental model of HIV and hepatitis C transmission through sexual contact and sharing of drug use equipment. SETTING Toronto and Ottawa, Canada. PARTICIPANTS Simulated population of each city. INTERVENTIONS Zero to five supervised injection facilities. MEASUREMENTS Direct health-care costs and quality-adjusted life-years (QALYs) over 20 years, discounted at 5% per year; incremental cost-effectiveness ratios. FINDINGS In Toronto, one facility cost $4.1 million and resulted in a gain of 385 QALYs over 20 years, for an incremental cost-effectiveness ratio (ICER) of $10,763 per QALY [95% credible interval (95CrI): cost-saving to $278,311]. Establishing one facility in Ottawa had an ICER of $6127 per QALY (95CrI: cost-saving to $179,272). At a $50,000 per QALY threshold, three facilities would be cost-effective in Toronto and two in Ottawa. The probability that establishing three, four, or five facilities in Toronto was cost-effective was 17, 21, and 41%, respectively. Establishing one, two, or three facilities in Ottawa was cost-effective with 13, 35, and 41% probability, respectively. Establishing no facility was unlikely to be the most cost-effective option (14% in Toronto and 10% in Ottawa). In both cities, results were robust if the reduction in needle-sharing among clients of the facilities was at least 50% and fixed operating costs were less than $2.0 million. CONCLUSIONS Using a $50,000 per quality-adjusted life-years threshold for cost-effectiveness, it is likely to be cost-effective to establish at least three legally sanctioned spaces for supervised injection of illicitly obtained drugs in Toronto, Canada and two in Ottawa, Canada.

Abstract
BACKGROUND AND AIMS We aimed to assess the incidence and progression of chronic kidney disease (CKD) following hepatitis C virus (HCV) seroconversion. METHODS This retrospective cohort study included Veterans with a confirmed HCV seroconversion between 2001 and 2014 and Veterans with negative HCV testing over the same time period. The outcomes included development of advanced CKD (eGFR < 60 mL/min/1.73 m(2) on two separate occasions at least 90 days apart, plus a ≥ 10 mL/min/1.73 m(2) decline from baseline) and progressive CKD (decline in eGFR of ≥ 30 mL/min/1.73 m(2) from baseline). Multivariable Cox proportional hazards models were used to evaluate the association between HCV and incident advanced and progressive CKD. RESULTS The final cohort consisted of 71,528 Veterans, including 2589 with recently seroconverted HCV. Over a mean follow-up of 6 years, 36% of patients with and 31% without HCV developed advanced CKD (p < 0.001), and 35% of patients with vs. 26% without HCV developed progressive CKD (p < 0.001). After controlling for traditional risk factors, recently seroconverted HCV+ patients were significantly less likely to develop advanced CKD (HR 0.86; 95% CI 0.79, 0.92), and HCV status was not significantly associated with progressive CKD (HR 0.93; 95% CI 0.86, 1.00). Factors associated with developing advanced and progressive CKD included older age, female sex, diabetes, hypertension, development of cirrhosis, and substance abuse. CONCLUSIONS In this cohort of newly infected US Veterans, HCV infection was associated with decreased incidence of advanced and unchanged risk of progressive CKD, suggesting a larger role for traditional risk factors in the development of CKD after HCV seroconversion.

Abstract
UNLABELLED Recently approved, interferon-free medication regimens for treating hepatitis C are highly effective, but extremely costly. We aimed to identify cost-effective strategies for managing treatment-naïve U.S. veterans with new hepatitis C medication regimens. We developed a Markov model with 1-year cycle length for a cohort of 60-year-old veterans with untreated genotype 1 hepatitis C seeking treatment in a typical year. We compared using sofosbuvir/ledipasvir or ombitasvir/ritonavir/paritaprevir/dasabuvir to treat: (1) any patient seeking treatment; (2) only patients with advanced fibrosis or cirrhosis; or (3) patients with advanced disease first and healthier patients 1 year later. The previous standard of care, sofosbuvir/simeprevir or sofosbuvir/pegylated interferon/ribavirin, was included for comparison. Patients could develop progressive fibrosis, cirrhosis, or hepatocellular carcinoma, undergo transplantation, or die. Complications were less likely after sustained virological response. We calculated the incremental cost per quality-adjusted life year (QALY) and varied model inputs in one-way and probabilistic sensitivity analyses. We used the Veterans Health Administration perspective with a lifetime time horizon and 3% annual discounting. Treating any patient with ombitasvir-based therapy was the preferred strategy ($35,560; 14.0 QALYs). All other strategies were dominated (greater costs/QALY gained than more effective strategies). Varying treatment efficacy, price, and/or duration changed the preferred strategy. In probabilistic sensitivity analysis, treating any patient with ombitasvir-based therapy was cost-effective in 70% of iterations at a $50,000/QALY threshold and 65% of iterations at a $100,000/QALY threshold. CONCLUSION Managing any treatment-naïve genotype 1 hepatitis C patient with ombitasvir-based therapy is the most economically efficient strategy, although price and efficacy can impact cost-effectiveness. It is economically unfavorable to restrict treatment to patients with advanced disease or use a staged treatment strategy. (Hepatology 2016;63:428-436).

Abstract
BACKGROUND Changes in lipid levels over time after acquiring HCV infection, and how they differ from HCV-uninfected persons are unknown. METHODS We used ERCHIVES to identify those with a known HCV seroconversion window and persistently negative controls. We excluded subjects with HIV and hepatitis B and those who received lipid lowering agents. Total Cholesterol (TC), low-density lipoproteins (LDL), high-density lipoproteins (HDL), triglycerides (TG) and non-HDL cholesterol were retrieved at yearly intervals and plotted over time. RESULTS Among 1,270 HCV+ and 5,070 HCV- subjects, median age [IQR] was 47[37,53] for HCV+ and 52[47,57] for the HCV- group; 69% were White and 91% were males in each group. Mean BMI [SD] was 26.94[6.73] in the HCV+ and 28.15 [5.98] in the HCV- group (P < 0.001). Over a 10-year follow-up period among HCV+ persons, TC decreased by (mean (SD) mg/dL) 12.06(36.95), LDL by 9.22(31.44), TG by 13.58(87.01) and non-HDL-C by 12.55(35.14). Among HCV- persons, TC cholesterol decreased by 4.15(31.21), LDL by 4.16(26.51); TG by 4.42(82.34) and non-HDL-C by 5.78(30.17). CONCLUSIONS After HCV acquisition, TC, LDL, TG and non-HDL-C progressively decline over time independent of BMI and liver fibrosis. Consequences of lipid changes and the need and optimal timing of lipid lowering therapy in HCV+ persons require further study.

Abstract
BACKGROUND In this era of a constantly changing landscape of antiviral treatment options for chronic viral hepatitis C (CHC), shared clinical decision-making addresses the need to engage patients in complex treatment decisions. However, little is known about the decision attributes that CHC patients consider when making treatment decisions. We identify key patient-centered decision attributes, and explore relationships among these attributes, to help inform the development of a future CHC shared decision-making aid. METHODS Semi-structured qualitative interviews with CHC patients at four Veterans Health Administration (VHA) hospitals, in three comparison groups: contemplating CHC treatment at the time of data collection (Group 1), recently declined CHC treatment (Group 2), or recently started CHC treatment (Group 3). Participant descriptions of decision attributes were analyzed for the entire sample as well as by patient group and by gender. RESULTS Twenty-nine Veteran patients participated (21 males, eight females): 12 were contemplating treatment, nine had recently declined treatment, and eight had recently started treatment. Patients on average described eight (range 5-13) decision attributes. The attributes most frequently reported overall were: physical side effects (83%); treatment efficacy (79%), new treatment drugs in development (55%); psychological side effects (55%); and condition of the liver (52%), with some variation based on group and gender. Personal life circumstance attributes (such as availability of family support and the burden of financial responsibilities) influencing treatment decisions were also noted by all participants. Multiple decision attributes were interrelated in highly complex ways. CONCLUSIONS Participants considered numerous attributes in their CHC treatment decisions. A better understanding of these attributes that influence patient decision-making is crucial in order to inform patient-centered clinical approaches to care (such as shared decision-making augmented with relevant decision-making aids) that respond to patients' needs, preferences, and circumstances.

Abstract
This review will focus on the efficacy and tolerability of the combination of sofosbuvir and simeprevir in genotype 1 chronic HCV infection. The goal of HCV therapy is to attain cure, which is defined by the US FDA as a sustained virologic response (SVR) or undetectable HCV RNA 12 weeks after HCV therapy, based on data confirming that over 99% patients who achieve this milestone have durable clearance of the infection. SVR12 (undetectable HCV RNA 12 weeks post-treatment) is the mostly commonly used end point to evaluate effectiveness of HCV therapy and will be used interchangeably with SVR in this review. Some of the data presented in this paper are from peer reviewed abstracts presented in major international conferences and are not yet published as manuscripts.

Abstract
Effectiveness, safety and tolerability of boceprevir (BOC) and telaprevir (TPV) in actual clinical settings remain unknown. We determined rates of sustained virologic response (SVR) and haematologic adverse effects among persons treated with BOC- or TPV-containing regimens, compared with pegylated interferon/ribavirin (PEG/RBV). Using an established cohort of hepatitis C virus (HCV)-infected persons, Electronically Retrieved Cohort of HCV Infected Veterans (ERCHIVES), we identified those treated with a BOC- or TPV-containing regimen and HCV genotype 1-infected controls treated with PEG/RBV. We excluded those with HIV coinfection and missing HCV RNA values to determine SVR. Primary endpoints were SVR (undetectable HCV RNA ≥12 weeks after treatment completion) and haematologic toxicity (grade 3/4 anaemia, neutropenia and thrombocytopenia). We evaluated 2288 persons on BOC-, 409 on TPV-containing regimen and 6308 on PEG/RBV. Among these groups, respectively, 31%, 43% and 9% were treatment-experienced; 17%, 37% and 14% had baseline cirrhosis; 63%, 54% and 48% were genotype 1a. SVR rates among noncirrhotics were as follows: treatment naïve: 65% (BOC), 67% (TPV) and 31% (PEG/RBV); treatment experienced: 57% (BOC), 54% (TPV) and 13% (PEG/RBV); (P-value not significant for BOC vs TPV; P < 0.0001 for BOC or TPV vs PEG/RBV). Haematologic toxicities among BOC-, TPV- and PEG/RBV-treated groups were as follows: grade 3/4 anaemia 7%, 11% and 3%; grade 4 thrombocytopenia 2.2%, 5.4% and 1.7%; grade 4 neutropenia 8.2%, 5.6% and 3.4%. SVR rates are higher and closer to those reported in pivotal clinical trials among BOC- and TPV-treated persons compared with PEG/RBV-treated persons. Haematologic adverse events are frequent, but severe toxicity is uncommon.

Abstract
UNLABELLED 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) have been variably noted to affect hepatitis C virus (HCV) treatment response, fibrosis progression, and hepatocellular carcinoma (HCC) incidence, with some having a more potent effect than others. We sought to determine the impact of adding statins to antiviral therapy upon sustained virological response (SVR) rates, fibrosis progression, and HCC development among HCV-infected persons using the Electronically Retrieved Cohort of HCV Infected Veterans (ERCHIVES), an established, longitudinal, national cohort of HCV-infected veterans. Within ERCHIVES, we identified those who received HCV treatment and a follow-up of >24 months after treatment completion. We excluded those with human immunodeficiency virus coinfection, hepatitis B surface antigen positivity, cirrhosis, and HCC at baseline. Our main outcomes were liver fibrosis progression measured by FIB-4 scores, SVR rates, and incident HCC (iHCC). Among 7,248 eligible subjects, 46% received statin therapy. Statin use was significantly associated with attaining SVR (39.2% vs. 33.3%; P < 0.01), decreased cirrhosis development (17.3% vs. 25.2%; P < 0.001), and decreased iHCC (1.2% vs. 2.6%; P < 0.01). Statins remained significantly associated with increased odds of SVR (odds ratio = 1.44; 95% confidence interval [CI] = 1.29, 1.61), but lower fibrosis progression rate, lower risk of progression to cirrhosis (hazard ratio [HR] = 0.56; 95% CI = -0.50, 0.63), and of incident HCC (HR = 0.51; 95% CI = 0.34, 0.76) after adjusting for other relevant clinical factors. CONCLUSIONS Statin use was associated with improved virological response (VR) rates to antiviral therapy and decreased progression of liver fibrosis and incidence of HCC among a large cohort of HCV-positive Veterans. These data support the use of statins in patients with HCV.

Abstract
Chronic hepatitis C virus (HCV) viral infection is the most common blood-borne viral infection and approximately 2%-3% of the world’s population or 170-200 million people are infected. In the United States as many as 3-5 million people may have HCV. Psychiatric and substance use disorders (SUDs) are common co-morbid conditions found in people with HCV and are factors in predisposing people to HCV infection. Also, these co-morbidities are reasons that clinicians exclude people from antiviral therapy in spite of evidence that people with HCV and co-morbid psychiatric and SUD can be safely and effectively treated. Furthermore, the neuropsychiatric side effects of interferon (IFN), until recently the mainstay of antiviral therapy, have necessitated an appreciation and assessment of psychiatric co-morbidities present in people with HCV. The availability of new medications and IFN-free antiviral therapy medication combinations will shorten the duration of treatment and exposure to IFN and thus decrease the risk of neuropsychiatric side effects. This will have the consequence of dramatically altering the clinical landscape of HCV care and will increase the number of eligible treatment candidates as treatment of people with HCV and co-morbid psychiatric and SUDs will become increasingly viable. While economically developed countries will rely on expensive IFN-free antiviral therapy, less developed countries will likely continue to use IFN-based therapies at least until such time as IFN-free antiviral medications become generic. The current manuscript discusses the efficacy and viability of treating HCV in people with psychiatric and SUDs comorbidities, the treatment of the neuropsychiatric side effects of IFN -based therapies and the impact of new medications and new treatment options for HCV that offer the promise of increasing the availability of antiviral therapy in this vulnerable population.

Abstract
IMPORTANCE Knowing the rate of liver fibrosis progression in hepatitis C virus (HCV)-infected persons can help inform patients and providers (clinicians, medical institutions or organizations, and third-party payers) in making treatment decisions. OBJECTIVE To determine the rate and factors associated with liver fibrosis progression and hepatic decompensation in persons after acquiring HCV infection. DESIGN, SETTING, AND PARTICIPANTS Secondary data analysis of persons in the Electronically Retrieved Cohort of HCV Infected Veterans (ERCHIVES), a national Veterans Affairs (VA) database, between 2002 and 2012. Among 610 514 persons in ERCHIVES (half were HCV positive), we identified those with an initial negative and subsequent positive test result for HCV antibody and positive HCV RNA test result (HCV+). Controls had 2 negative HCV antibody test results (HCV-) in a comparable time frame and were matched 1:1 on age (in 5-year blocks), race, and sex. We excluded persons with human immunodeficiency virus, hepatitis B, less than 24 months of follow-up, hepatocellular carcinoma, and cirrhosis at baseline. MAIN OUTCOMES AND MEASURES Progression of liver fibrosis as estimated by the Fibrosis-4 (FIB-4) index; development of cirrhosis, defined by a FIB-4 score greater than 3.5; and development of hepatic decompensation. RESULTS The evaluable data set consisted of 1840 persons who were HCV+ and 1840 HCV- controls. The HCV+ persons were younger and had a lower mean (SD) body mass index (27.39 [5.51] vs 29.49 [6.16]; P < .001), a higher prevalence of alcohol and drug abuse and dependence diagnoses, and higher serum aminotransferase levels, but had a lower prevalence of diabetes and hypertension. Fibrosis progression started early after infection among HCV+ persons and tapered off after 5 years. A total of 452 cirrhosis and 85 hepatic decompensation events were recorded. After 10 years of follow-up, HCV+ persons were more likely to have a diagnosis of cirrhosis compared with HCV- controls (18.4% vs 6.1%). Nine years after diagnosis of cirrhosis, hepatic decompensation events were uncommon but had a higher rate in the HCV+ group (1.79% vs 0.33%). CONCLUSIONS AND RELEVANCE Persons who seroconverted for HCV have a more rapid progression of liver fibrosis and accelerated time to development of cirrhosis after seroconversion compared with HCV- controls. Fibrosis progression occurs early after infection; however, hepatic decompensation is uncommon after diagnosis of cirrhosis.

Abstract
Chronic hepatitis C virus (HCV) is the most common blood-borne pathogen in the United States. HCV disproportionately affects Veterans Affairs (VA) health-care users: 174,302 HCV-infected veterans were in VA care in 2013, making the VA the world's largest HCV care provider. This systematic review identified 546 articles related to HCV in the VA. After assessment by 2 independent reviewers, 28 articles describing prevalence and treatment of HCV in VA users ultimately met inclusion criteria. Most VA patients currently living with HCV infection were born between 1945 and 1965 and were infected with HCV between 1970 and 1990. To prevent HCV-related complications such as cirrhosis, hepatocellular carcinoma, and death, medical personnel must identify and treat HCV. However, antiviral therapy has historically been limited by medication side effects, contraindications, and patient acceptance. Although treatment initiation rates are higher in the VA than in the general United States, only 23% of VA HCV patients have received treatment and, of those, only a minority were cured. Recent development of more effective and tolerable antiviral agents represents a major pharmacological breakthrough. Eradication of HCV is theoretically possible for the majority of HCV patients for the first time, although new barriers, such as high drug costs, may limit future uptake.

Abstract
The care of hepatitis C virus (HCV) in African Americans represents an opportunity to address a major health disparity in medicine. In all facets of HCV infection, African Americans are inexplicably affected, including in the prevalence of the virus, which is higher among them compared with most of the racial and ethnic groups. Ironically, although fibrosis rates may be slow, hepatocellular carcinoma and mortality rates appear to be higher among African Americans. Sustained viral response (SVR) rates have historically significantly trailed behind Caucasians. The reasons for this gap in SVR are related to both viral and host factors. Moreover, low enrollment rates in clinical trials hamper the study of the efficacy of anti-viral therapy. Nevertheless, the gap in SVR between African Americans and Caucasians may be narrowing with the use of direct-acting agents. Gastroenterologists, hepatologists, primary care physicians, and other health-care providers need to address modifiable risk factors that affect the natural history, as well as treatment outcomes, for HCV among African Americans. Efforts need to be made to improve awareness among health-care providers to address the differences in screening and referral patterns for African Americans.

Abstract
BACKGROUND Triple therapy for the treatment of hepatitis C virus (HCV) with first-generation directly acting antiviral agents, the non-structural serine protease inhibitors boceprevir (BOC) and telaprevir have resulted in improved sustained virologic response (SVR) rates. However, a high incidence of adverse events (AEs), high pill burdens and drug interactions remain significant barriers to successful completion of therapy. The aim of this study was to evaluate the AEs observed with BOC triple therapy in comparison to IFN-free sofosbuvir/ribavirin (SOF/RBV) therapy in HCV monoinfected, genotype-1 (GT-1) individuals. METHODS We retrospectively evaluated HCV monoinfected, treatment-naïve or -experienced, GT-1 individuals treated with either BOC/IFN/RBV at the Veterans Affairs Medical Center, Baltimore (n = 97) or SOF/RBV in the NIAID SPARE clinical trial (n = 60). AEs, namely hematologic (hemoglobin, neutrophil and platelet counts), hepatic (alanine transaminase or bilirubin) and renal (eGFR), were measured according to the DAIDS toxicity table (version 1.0). RESULTS BOC/IFN/RBV was associated with significantly more AEs, most commonly neutropenia, anemia and thrombocytopenia. In the SOF/RBV cohort, five (8 %) patients discontinued treatment early, but none (0 %) were because of AEs, while 60 (62 %) patients on triple therapy discontinued treatment early, 34 (57 %) because of AEs. SVR24 rates were 68 versus 34 % with SOF/RBV versus BOC/IFN/RBV. CONCLUSIONS SOF/RBV treatment was associated with fewer side effects than BOC-based triple therapy, appearing to be a safer and more tolerable alternative for HCV GT-1 subjects. These results show that emerging IFN-free therapies may enhance patient adherence, allowing treatment of larger number of patients with improved efficacy.

Abstract
Chronic hepatitis C virus infection affects around 150 million persons, and 350,000 persons worldwide die of this disease each year. Although the data on its natural history are incomplete, after the acute infection, most patients develop chronic forms of hepatitis C with variable stages of fibrosis. In these patients, continual inflammatory activity can cause significant fibrosis, cirrhosis, decompensation of the liver disease, or hepatocarcinoma. In the next few years, it is expected that hepatitis C virus infection and its complications will significantly increase, as will the incidence of hepatocarcinoma in Spain. This review presents the data on the natural history of hepatitis C virus infection and discusses the potential impact of antiviral therapy on the distinct stages of the disease.

Abstract
BACKGROUND Hepatitis C virus infection affects around 3% of the world population or approximately 160 million people. A variable proportion (5% to 40%) of the infected people develop clinical symptoms. Hence, hepatitis C virus is a leading cause of liver-related morbidity and mortality with hepatic fibrosis, end-stage liver cirrhosis, and hepatocellular carcinoma as the dominant clinical sequelae. Combination therapy with pegylated (peg) interferon-alpha and ribavirin achieves sustained virological response (that is, undetectable hepatitis C virus RNA in serum by sensitivity testing six months after the end of treatment) in approximately 40% to 80% of treated patients, depending on viral genotype. Recently, a new class of drugs have emerged for hepatitis C infection, the direct acting antivirals, which in combination with standard therapy or alone can lead to sustained virological response in 80% or more of treated patients. Aminoadamantanes, mostly amantadine, are antiviral drugs used for the treatment of patients with chronic hepatitis C. We have previously systematically reviewed amantadine versus placebo or no intervention and found no significant effects of the amantadine on all-cause mortality or liver-related morbidity and on adverse events in patients with hepatitis C. Overall, we did not observe a significant effect of amantadine on sustained virological response. In this review, we systematically review aminoadamantanes versus other antiviral drugs. OBJECTIVES To assess the beneficial and harmful effects of aminoadamantanes versus other antiviral drugs for patients with chronic hepatitis C virus infection by conducting a systematic review with meta-analyses and trial sequential analyses of randomised clinical trials. SEARCH METHODS The Cochrane Hepato-Biliary Group Controlled Trials Register (1996 to December 2013), the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 11 of 12, 2013), MEDLINE (1946 to December 2013), EMBASE (1974 to December 2013), Science Citation Index EXPANDED (1900 to December 2013), the WHO International Clinical Trials Registry Platform (www.who.int/ictrp), Google Scholar, and Eudrapharm up to December 2013. Furthermore, full text searches were conducted until December 2013. SELECTION CRITERIA Randomised clinical trials assessing aminoadamantanes in participants with chronic hepatitis C virus infection. DATA COLLECTION AND ANALYSIS Two authors independently extracted data. RevMan Analysis was used for statistical analysis of dichotomous data using risk ratio (RR) with 95% confidence intervals (CI). Methodological domains were used to assess the risk of systematic errors ('bias'). We used trial sequential analysis to assess risk of random errors ('play of chance'). MAIN RESULTS Six randomised clinical trials with 581 participants with chronic hepatitis C were included. All trials had high risk of bias. The included trials compared amantadine versus other antiviral drugs: ribavirin, mycophenolate mofetil, interferon-alpha, or interferon-gamma. Standard antiviral therapy (interferon-alpha, interferon-alpha plus ribavirin, or peg interferon alpha) was administered equally to the intervention and the control groups in five trials, depending on when the trial was conducted. Four trials compared amantadine versus ribavirin. There were no deaths or liver-related morbidity in the two intervention groups (0/216 (0%) versus 0/211 (0%); 4 trials; very low quality of the evidence). The lower estimated risk for (serious) adverse events leading to treatment discontinuation with amantadine was imprecise (RR 0.56, 95% CI 0.27 to 1.16; based on 10/216 (5%) versus 18/211 (9%) participants in 4 trials; very low quality of the evidence). There were more participants with failure of sustained virological response in the amantadine group than in the ribavirin group (206/216 (96%) versus 176/211 (84%); RR 1.14, 95% CI 1.07 to 1.22, 4 trials; low quality of the evidence). Amantadine versus ribavirin more often failed to achieve end-of follow-up biochemical response (41/46 (89%) versus 31/46 (67%); RR 1.31, 95% CI 1.05 to 1.63; 2 trials; very low quality of the evidence). One trial compared amantadine versus mycophenolate mofetil. There were no significant differences between the two treatment groups, except that amantadine was inferior to mycophenolate mofetil regarding the outcome failure to achieve end-of treatment virological response (low quality of evidence). One trial each compared amantadine versus interferon-alpha or interferon-gamma. Both comparisons showed no significant differences in the treatment outcomes (very low quality of the evidence). The observed effects could be due to real effects, systematic errors (bias), or random errors (play of chance). This possible influence on the observed effect by play of chance is due to the fact that trial sequential analyses could not confirm our findings. We were not able to perform meta-analyses on failure of histological improvement and quality of life due to lack of valid data in all trial comparisons. AUTHORS' CONCLUSIONS This systematic review has identified evidence of very low quality for the key outcomes of all-cause mortality or liver-related morbidity and adverse events in people with chronic hepatitis C when treated with amantadine compared with ribavirin, mycophenolate, interferon-alpha, or interferon-gamma. The timeframe for measuring the composite outcome was insufficient in the included trials. There was low quality evidence that amantadine led to more participants who failed to achieve sustained virological response compared with ribavirin. This observation may be real or caused by systematic errors (bias), but it does not seem to be caused by random error (play of chance). Due to the low quality of the evidence, we are unable to determine definitively whether amantadine is less effective than other antivirals in patients with chronic hepatitis C. As it appears less likely that future trials assessing amantadine or potentially other aminoadamantanes for patients with chronic hepatitis C would show strong benefits, it is probably better to focus on the assessments of other direct acting antiviral drugs. We found no evidence assessing other aminoadamantanes in randomised clinical trials in order to recommend or refute their use.

Abstract
BACKGROUND Interferon-containing regimens for the treatment of hepatitis C virus (HCV) infection are associated with increased toxic effects in patients who also have cirrhosis. We evaluated the interferon-free combination of the protease inhibitor ABT-450 with ritonavir (ABT-450/r), the NS5A inhibitor ombitasvir (ABT-267), the nonnucleoside polymerase inhibitor dasabuvir (ABT-333), and ribavirin in an open-label phase 3 trial involving previously untreated and previously treated adults with HCV genotype 1 infection and compensated cirrhosis. METHODS We randomly assigned 380 patients with Child-Pugh class A cirrhosis to receive either 12 or 24 weeks of treatment with ABT-450/r-ombitasvir (at a once-daily dose of 150 mg of ABT-450, 100 mg of ritonavir, and 25 mg of ombitasvir), dasabuvir (250 mg twice daily), and ribavirin administered according to body weight. The primary efficacy end point was a sustained virologic response 12 weeks after the end of treatment. The rate of sustained virologic response in each group was compared with the estimated rate with a telaprevir-based regimen (47%; 95% confidence interval [CI], 41 to 54). A noninferiority margin of 10.5 percentage points established 43% as the noninferiority threshold; the superiority threshold was 54%. RESULTS A total of 191 of 208 patients who received 12 weeks of treatment had a sustained virologic response at post-treatment week 12, for a rate of 91.8% (97.5% CI, 87.6 to 96.1). A total of 165 of 172 patients who received 24 weeks of treatment had a sustained virologic response at post-treatment week 12, for a rate of 95.9% (97.5% CI, 92.6 to 99.3). These rates were superior to the historical control rate. The three most common adverse events were fatigue (in 32.7% of patients in the 12-week group and 46.5% of patients in the 24-week group), headache (in 27.9% and 30.8%, respectively), and nausea (in 17.8% and 20.3%, respectively). The hemoglobin level was less than 10 g per deciliter in 7.2% and 11.0% of patients in the respective groups. Overall, 2.1% of patients discontinued treatment owing to adverse events. CONCLUSIONS In this phase 3 trial of an oral, interferon-free regimen evaluated exclusively in patients with HCV genotype 1 infection and cirrhosis, multitargeted therapy with the use of three new antiviral agents and ribavirin resulted in high rates of sustained virologic response. Drug discontinuations due to adverse events were infrequent. (Funded by AbbVie; TURQUOISE-II ClinicalTrials.gov number, NCT01704755.).

Abstract
Background. Understanding the predictors of mortality in individuals with human immunodeficiency virus and hepatitis C virus (HIV/HCV) coinfection can be useful in management of these patients. Methods. We used the Electronically Retrieved Cohort of HCV Infected Veterans (ERCHIVES) for these analyses. Multivariate Cox-regression models were used to determine predictors of mortality. Results. Among 8,039 HIV infected veterans, 5251 (65.3%) had HCV coinfection. The all-cause mortality rate was 74.1 (70.4-77.9) per 1000 person-years (PY) among veterans with HIV/HCV coinfection and 39.8 (36.3-43.6) per 1000 PY for veterans with HIV monoinfection. The multivariable adjusted hazard ratio (95% confidence interval) of all-cause mortality for HCV infection was 1.58 (1.36-1.84). Positive predictors of mortality included decompensated liver disease (2.33 (1.98-2.74)), coronary artery disease (1.74 (1.32-2.28)), chronic kidney disease (1.62 (1.36-1.92)), and anemia (1.58 (1.31-1.89)). Factors associated with reduced mortality included HCV treatment (0.41 (0.27-0.63)) and higher CD4 count (0.90 (0.87-0.93) per 100 cells/ μ L higher count). Data were insufficient to make informative analyses of the role of HCV virologic response. Conclusion. HCV coinfection was associated with substantial increased risk of mortality among HIV infected veterans. HCV treatment was associated with significantly lower risk of mortality.

Abstract
BACKGROUND Infection with the hepatitis C virus (HCV) has been considered a major cause of mortality, morbidity and resource utilisation in the US. In addition, HCV is the main cause of hepatocellular cancer (HCC) in the US. Recent developments in the diagnosis and treatment of HCV, including new recommendations pertaining to screening for HCV by the Centers for Disease Control and Prevention and newer treatment regimens with high efficacy, short duration and the potential for interferon-free therapies, have energised the health care practitioners regarding HCV management. AIM To assess the full impact of HCV burden on clinical, economic and patient-reported outcomes. METHODS An expert panel was convened to assess the full impact of HCV burden on a number of important outcomes using an evidence-based approach predicated on Grading of Recommendations Assessment, Development and Evaluation methodology. The literature was summarised, graded using an evidence-based approach and presented during the workshop. Workshop presentations were intended to review recent, relevant evidence-based literature and provide graded summary statements pertaining to HCV burden on topics including the relationships between HCV and the development of important outcomes. RESULTS The associations of HCV with cirrhosis, HCC, liver-related mortality, type 2 diabetes mellitus, rheumatological diseases and quality of life impairments are supported by strong evidence. Also, there is strong evidence that sustained viral eradication of HCV can improve important outcomes such as mortality and quality of life. CONCLUSIONS The current evidence suggests that HCV has been associated with tremendous clinical, economic and quality of life burden.

Abstract
BACKGROUND Pegylated interferon (peginterferon) plus ribavirin is the recommended treatment for patients with chronic hepatitis C, but systematic assessment of the effect of this treatment compared with interferon plus ribavirin is needed. OBJECTIVES To systematically evaluate the benefits and harms of peginterferon plus ribavirin versus interferon plus ribavirin for patients with chronic hepatitis C. SEARCH METHODS We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Science Citation Index-Expanded, and LILACS. We also searched conference abstracts, journals, and grey literature. The last searches were conducted in September 2013. SELECTION CRITERIA We included randomised clinical trials comparing peginterferon plus ribavirin versus interferon plus ribavirin with or without co-intervention(s) (e.g., other antiviral drugs) for chronic hepatitis C. Quasi-randomised and observational studies retrieved through the searches for randomised clinical trials were also considered for reports of harms. Our primary outcomes were liver-related morbidity, all-cause mortality, serious adverse events, adverse events leading to treatment discontinuation, other adverse events, and quality of life. Our secondary outcome was sustained virological response in serum, that is, undetectable hepatitis C virus RNA in serum by sensitive tests six months after the end of treatment. DATA COLLECTION AND ANALYSIS Two review authors independently used a standardised data collection form. We meta-analysed data with both fixed-effect and random-effects models. For each outcome, we calculated the odds ratio (OR) (for liver-related morbidity or all-cause mortality) or the risk ratio (RR) along with 95% confidence interval (CI) based on intention-to-treat analysis. We used domains of the trials to assess the risk of systematic errors (bias) and trial sequential analyses to assess the risk of random errors (play of chance).For each outcome, we calculated the RR with 95% CI based on intention-to-treat analysis. Effects of interventions on outcomes were assessed according to GRADE. MAIN RESULTS We included 27 randomised trials with 5938 participants. All trials had high risk of bias. We considered that the risk of bias did not impact on the quality of evidence for liver-related mortality and adverse event outcomes, but it did for virological response. All trials compared peginterferon alpha-2a or peginterferon alpha-2b plus ribavirin versus interferon plus ribavirin for participants with chronic hepatitis C. Three trials administered co-interventions (amantadine hydrochloride 200 mg daily to both intervention groups), and 24 trials were conducted without co-interventions. The effect observed between the two intervention groups regarding liver-related morbidity plus all-cause mortality (5/907 (0.55%) versus 4/882 (0.45%) was imprecise: OR 1.14 ( 95% CI 0.38 to 3.42; five trials; low quality of evidence), as was the risk of adverse events leading to treatment discontinuation (332/2692 (12.3%) versus 409/2176 (18.8%); RR 0.86, 95% CI 0.68 to 1.09; 15 trials; low quality of evidence) or regarding adverse events leading to treatment discontinuation (332/2692 (12.3%) versus 409/2176 (18.8%); RR 0.86, 95% CI 0.66 to 1.12; 17 trials; low quality of evidence). However, peginterferon plus ribavirin versus interferon plus ribavirin significantly increased the risk of neutropenia (332/2202 (15.1%) versus 117/1653 (7.1%); RR 2.15, 95% CI 1.76 to 2.61; 13 trials), thrombocytopenia (65/1113 (5.8%) versus 23/1082 (2.1%); RR 2.63, 95% CI 1.68 to 4.11; 10 trials), arthralgia (517/1740 (29.7%) versus 282/1194 (23.6%); RR 1.19, 95% CI 1.05 to 1.35; four trials), injection site reaction (627/1168 (53.7%) versus 186/649 (28.7%); RR 1.71, 95% CI 1.50 to 1.93; four trials), and nausea (606/1784 (34.0%) versus 354/1239 (28.6%); RR 1.13, 95% CI 1.01 to 1.26; four trials). The most frequent adverse event was fatigue, which occurred in 57% of participants (2024/3608). No significant difference was noted between peginterferon plus ribavirin versus interferon plus ribavirin in terms of fatigue (1177/2062 (57.1%) versus 847/1546 (54.8%); RR 1.01, 95% CI 0.96 to 1.07; 12 trials). No significant differences were reported between the two treatment groups regarding anaemia, headache, rigours, myalgia, pyrexia, weight loss, asthenia, depression, insomnia, irritability, alopecia, pruritus, skin rash, thyroid malfunction, decreased appetite, or diarrhoea. We were unable to identify any data on quality of life. Peginterferon plus ribavirin versus interferon plus ribavirin seemed to significantly increase the number of participants achieving sustained virological response (1673/3300 participants (50.7%) versus 1081/2804 patients (36.7%); RR 1.39, 95% CI 1.25 to 1.56; I2 = 64%; 27 trials; very low quality of evidence). However, the risk of bias in the 13/27 (48.1%) trials reporting on this outcome was high and was considered only 'lower' in the remainder. Because the conventional meta-analysis did not reach its required information size (n = 14,486 participants), we used trial sequential analysis to control for risks of random errors. Again, in this analysis, the estimated effect was statistically significant in favour of peginterferon. Subgroup analyses according to risk of bias, viral genotype, baseline viral load, past treatment history, and type of intervention yielded similarly significant results favouring peginterferon over interferon on the outcome of sustained virological response. AUTHORS' CONCLUSIONS Peginterferon plus ribavirin versus interferon plus ribavirin seems to significantly increase the proportion of patients with sustained virological response, as well as the risk of certain adverse events. However, we have insufficient evidence to recommend or reject peginterferon plus ribavirin for liver-related morbidity plus all-cause mortality compared with interferon plus ribavirin. The clinical consequences of achieved sustained virological response are unknown, as sustained virological response is still an unvalidated surrogate outcome. We found no evidence of the potential benefits on quality of life in patients with achieved sustained virological response. Further high-quality research is likely to have an important impact on our confidence in the estimate of patient-relevant outcomes and is likely to change our estimates.There is very low quality evidence that peginterferon plus ribavirin increases the proportion of patients with sustained virological response in comparison with interferon plus ribavirin. There is evidence that it also increases the risk of certain adverse events.

Abstract
BACKGROUND A combination of weekly pegylated interferon (peginterferon) alpha and daily ribavirin still represents standard treatment of chronic hepatitis C infection in the majority of patients. However, it is not established which of the two licensed peginterferon products, peginterferon alpha-2a or peginterferon alpha-2b, is the most effective and has a better safety profile. OBJECTIVES To systematically evaluate the benefits and harms of peginterferon alpha-2a versus peginterferon alpha-2b in head-to-head randomised clinical trials in patients with chronic hepatitis C. SEARCH METHODS We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, Science Citation Index Expanded, and LILACS until October 2013. We also searched conference abstracts, journals, and grey literature. SELECTION CRITERIA We included randomised clinical trials comparing peginterferon alpha-2a versus peginterferon alpha-2b given with or without co-intervention(s) (for example, ribavirin) for chronic hepatitis C. Quasi-randomised studies and observational studies as identified by the searches were also considered for assessment of harms. Our primary outcomes were all-cause mortality, liver-related morbidity, serious adverse events, adverse events leading to treatment discontinuation, other adverse events, and quality of life. The secondary outcome was sustained virological response in the blood serum. DATA COLLECTION AND ANALYSIS Two authors independently used a standardised data collection form. We meta-analysed data with both the fixed-effect and the random-effects models. For each outcome we calculated the relative risk (RR) with 95% confidence interval (CI) based on intention-to-treat analysis. We used domains of the trials to assess the risk of systematic errors (bias) and trial sequential analyses to assess the risks of random errors (play of chance). Intervention effects on the outcomes were assessed according to GRADE. MAIN RESULTS We included 17 randomised clinical trials which compared peginterferon alpha-2a plus ribavirin versus peginterferon alpha-2b plus ribavirin in 5847 patients. All trials had a high risk of bias. Very few trials reported data on very few patients for the patient-relevant outcomes all-cause mortality, liver-related morbidity, serious adverse events, and quality of life. Accordingly, we were unable to conduct meta-analyses on all-cause mortality, liver-related morbidity, and quality of life. Twelve trials reported on adverse events leading to discontinuation of treatment without clear evidence of a difference between the two peginterferons (197/2171 (9.1%) versus 311/3169 (9.9%); RR 0.84, 95% CI 0.57 to 1.22; I2 = 44%; low quality evidence). A trial sequential analysis showed that we could exclude a relative risk reduction of 20% or more on this outcome. Peginterferon alpha-2a significantly increased the number of patients who achieved a sustained virological response in the blood serum compared with peginterferon alpha-2b (1069/2099 (51%) versus 1327/3075 (43%); RR 1.12, 95% CI 1.06 to 1.18; I2= 0%, 12 trials; moderate quality evidence). Trial sequential analyses supported this result. Subgroup analyses based on risk of bias, viral genotype, and treatment history yielded similar results. Trial sequential analyses supported the results in patients with genotypes 1 and 4, but not in patients with genotypes 2 and 3. AUTHORS' CONCLUSIONS There is lack of evidence on patient-important outcomes and paucity of evidence on adverse events. Moderate quality evidence suggests that peginterferon alpha-2a is associated with a higher sustained virological response in serum than with peginterferon alpha-2b. This finding may be affected by the high risk of bias of the included studies . The clinical consequences of peginterferon alpha-2a versus peginterferon alpha-2b are unknown, and we cannot translate an effect on sustained virological response into comparable clinical effects because sustained virological response is still an unvalidated surrogate outcome for patient-important outcomes. The lack of evidence on patient-important outcomes and the paucity of evidence on adverse events means that we are unable to draw any conclusions about the effects of one peginterferon over the other.

Abstract
The impact of pretreatment anaemia on survival in individuals with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) co-infection is not known. Moreover, HCV treatment is offered less frequently to individuals with anaemia, due to haematological side effects of the treatment regimen. This study aimed to determine the effect of HCV treatment on survival among HCV/HIV co-infected individuals with pretreatment anaemia using the Electronically Retrieved Cohort of HCV-Infected Veterans (ERCHIVES). Individuals with HCV/HIV co-infection were included in current analyses. Participants were considered treated if they were prescribed ≥ 4 weeks of HCV treatment. All-cause mortality data were obtained using record linkage. Survival analyses were performed using Cox proportional hazard models. Among 5000 HCV/HIV co-infected individuals, 1671 (33.4%) had pretreatment anaemia. In a follow-up period of up to 7 years (19,500 person-years), individuals with anaemia had significantly higher mortality rate compared with those without anaemia [144.2 (95% CI: 134.5-154.7) vs 47.5 (44.0-51.2) per 1000 person-years, respectively]. Among individuals with anaemia, HCV treatment was associated with significantly lower mortality rate [66.6 (44.3-100.2) vs 149.6 (139.2-160.5) per 1000 person-years, for treated vs untreated, respectively]. Treatment remained associated with substantial survival benefit after taking into account the effect of multiple comorbidities (hazards ratio: 0.34, 95% CI: 0.21-0.62). These data suggest that HCV/HIV co-infected individuals with pretreatment anaemia have significantly higher mortality compared with those without anaemia. HCV treatment is associated with substantial survival benefit in this group. Additional studies are needed to determine strategies to improve HCV treatment rates among this group.

Abstract
BACKGROUND & AIMS Hepatitis C virus (HCV) genotype 4 (G4) infection is common in the Middle East. Post-treatment long-term outcomes have not been reported in these patients. This study evaluates these outcomes in patients after interferon-based therapy. PATIENTS AND METHODS A total of 157 patients were followed from June 2001 to February 2012. Descriptive and analytical statistics, cumulative outcomes and the independent predictors of disease progression were calculated. RESULTS The overall age was 48.0 ± 11.8 years, 75 (47.8%) were males and 53 (70.7%) of 75 who were genotyped had G4. The follow-up period was 63.8 ± 32.8 months. Sustained virological response (SVR) was achieved in 62 (39.5%) and 24 (45.3%) patients in the whole group and the G4 subgroup respectively. Among the whole cohort and the G4 subgroup, disease progressed in 59 (37.6%) and 21 (39.6%), respectively, with less progression in the SVR groups; 15/62 (24.2%) and 3/24 (12.5%) compared with non-responders; 44 (46.3%) and 18 (62.1%) with P = 0.01 and 0.001 respectively. Multivariate logistic regression analysis showed that having diabetes mellitus (P = 0.03), higher baseline APRI score (P = 0.00) and non-SVR (P = 0.00) were independent predictors of disease progression. G4 patients showed similar results, but 'non-SVR' (P = 0.00) was the only independent predictor of progression. Eight patients died and four developed HCC all among the non-SVR group only. CONCLUSIONS This study describes, for the first time, the natural history and demonstrates the beneficial long-term effects of interferon-based therapy in HCV G4 patients.

Abstract
BACKGROUND & AIMS Individuals with chronic hepatitis C virus (HCV) infection and pretreatment anemia are less likely to begin and complete a full course of treatment for HCV. However, among those who are treated for HCV infection, the effect of treatment on mortality is not clear. METHODS We performed a retrospective analysis of 200,139 HCV-infected veterans using data from the Electronically Retrieved Cohort of Hepatitis C-Infected veterans (2001-2008). The effects of treatment and treatment duration on survival were compared based on data from 1820 treated and 27,690 untreated anemic HCV-infected veterans. The association between HCV treatment and mortality was estimated using the Cox proportional hazard models, with adjustments for potential confounders. The main outcome was all-cause mortality. RESULTS In multivariable analysis, pretreatment anemia was associated significantly with African American race (odds ratio [OR], 2.03; 95% confidence interval [CI], 1.95-2.11), chronic kidney disease (OR, 3.36; 95% CI, 3.23-3.51), and decompensated liver disease (OR, 3.69; 95% CI, 3.53-3.86). All-cause mortality for treated, anemic, HCV-infected veterans was lower (54.2 per 1000 person-years; 95% CI, 49.2-59.7 per 1000 person years) than for untreated, anemic HCV-infected veterans (146.8 per 1000 person-years; 95% CI, 144.2-149.4 per 1000 person-years). The adjusted hazard ratio for treatment of HCV in anemic veterans was 0.45 (95% CI, 0.39-0.51), which was reduced after exclusion of comorbidities (hazard ratio, 0.28; 95% CI, 0.22-0.37). CONCLUSIONS Based on a retrospective analysis of a veterans database, HCV therapy increases survival rates of individuals with pretreatment anemia. Additional studies are needed to determine strategies to increase rates of HCV therapy for this group.

Abstract
Background The long-term consequences of unsuccessful interferon-α based hepatitis C treatment on liver disease progression and survival have not been fully explored. Methods and Findings We performed retrospective analyses to assess long-term clinical outcomes among treated and untreated patients with hepatitis C virus in two independent cohorts from a United States Veterans Affairs Medical Center and a University Teaching Hospital. Eligible patients underwent liver biopsy during consideration for interferon-α based treatment between 1992 and 2007. They were assessed for the probability of developing cirrhosis and of dying during follow-up using Cox proportional hazards models, stratified by pretreatment liver fibrosis stage and adjusted for known risk factors for cirrhosis and characteristics affecting treatment selection. The major predictor was a time-dependent covariate for treatment outcome among four patient groups: 1) patients with sustained virological response to treatment; 2) treatment relapsers; 3) treatment nonresponders; and 4) never treated patients. Treatment nonresponders in both cohorts had a statistically significantly increased hazard of cirrhosis compared to never treated patients, as stratified by pretreatment liver fibrosis stage and adjusted for clinical and psychosocial risk factors that disproportionately affect patients who were ineligible for treatment (Veterans Affairs HR = 2.35, CI 1.18–4.69, mean follow-up 10 years, and University Hospital HR = 5.90, CI 1.50–23.24, mean follow-up 7.7 years). Despite their increased risk for liver disease progression, the overall survival of nonresponders in both cohorts was not significantly different from that of never treated patients. Conclusion These unexpected findings suggest that patients who receive interferon-α based therapies but fail to clear the hepatitis C virus may have an increased hazard of cirrhosis compared to untreated patients.

Abstract
UNLABELLED Hepatitis C is the most prevalent bloodborne viral disease in the United States and the deadliest. This year, the U.S. Preventive Services Task Force (USPSTF) will update its 2004 hepatitis C guideline, which recommends against screening asymptomatic adults for hepatitis C. This guideline has hampered public health efforts to encourage screening and identify and refer infected persons for care by declaring that such interventions were not supported by the evidence. A draft revision of the guideline, released on November 26, 2012, concludes that testing persons born between 1945 and 1965 probably has at least a small net benefit, but stops short of definitively recommending that this cohort be screened. This article examines the Task Force's process for writing its guidelines. It recommends that the Task Force adopt a balanced approach to evaluating the benefits and harms of screening; use the preponderance of the evidence as a standard for evaluating interventions that target serious public health problems; be transparent about the value judgments that go into its decisions; consider the wide variation in disease prevalence in diverse patient populations; and recommend screening asymptomatic adults for hepatitis C. CONCLUSION By taking a broader view of the evidence, the Task Force can write new guidelines that will serve efforts to curb the hepatitis C epidemic, rather than frustrate them.

Abstract
BACKGROUND While current medications used to treat patients with chronic hepatitis C virus (HCV) effectively produce sustained viral response (SVR), postponement of therapy is often times attributed to patient perceptions of unfavourable outcomes. However, an instrument to assess patient perceptions of therapy (i.e. treatment satisfaction) has not been developed. AIM To describe the development and validation the chronic Hepatitis C Virus Treatment Satisfaction (HCVTSat) instrument. METHODS Focus groups, expert review and cognitive debriefing were used to develop a draft 37-item instrument (scale: 1 = not important at all; 5 = extremely important). The preliminary instrument was administered to a pre-test sample of 145 patients through Mayo Clinic, Rochester, MN. A refined HCVTSat was administered to a main sample of 333 participants with a chronic HCV diagnosis through Harris Interactive. RESULTS The HCVTSat was completed by 333 participants with an average age of 51 (s.d. = 12.1) years, 55% male, current or previous HCV treatment experience, and a diagnosis of HCV for approximately 12 (s.d. = 8.9) years. Twelve items for the 3 dimensions, Treatment Experience (TE), Side Effects (SE) and Social Aspects (SA), were internally consistent (Cronbach's α range: 0.70-0.90), responsive and valid. Confirmatory factor analysis (goodness-of-fit indexes: χ(2) = 20.9, df = 23, P = 0.59; CFI = 1.00, GFI = 0.99, TFI = 1.00, RMSEA = 0.001) revealed a better fit with 9 items. All path coefficients were significant (P < 0.05). SE and SA were strong predictors of TE, while TE was positively associated with the 1-item global measure of TS (path coefficient = 0.12). CONCLUSIONS The 10-item HCVTSat demonstrated valid psychometric properties and assessed patient satisfaction with HCV therapies. However, additional studies are needed to validate the HCVTSat in conjunction with SVR and in patients in underrepresented populations.

Abstract
BACKGROUND The recent approval of two protease inhibitors, boceprevir and telaprevir, is likely to change the management of chronic hepatitis C virus (HCV) genotype 1 infection. OBJECTIVES We evaluated the long-term clinical outcomes and the cost effectiveness of therapeutic strategies using boceprevir with peginterferon plus ribavirin (PR) in comparison with PR alone for treating HCV genotype 1 infection in Portugal. METHODS A Markov model was developed to project the expected lifetime costs and quality-adjusted life-years (QALYs) associated with PR alone and the treatment strategies outlined by the European Medicines Agency in the boceprevir summary of product characteristics. The boceprevir-based therapeutic strategies differ according to whether or not the patient was previously treated and whether or not the patient had compensated cirrhosis. The model simulated the experience of a series of cohorts of chronically HCV-infected patients (each defined by age, sex, race and fibrosis score). All treatment-related inputs were obtained from boceprevir clinical trials - SPRINT-2, RESPOND-2 and PROVIDE. Estimates of the natural history parameters and health state utilities were based on published studies. Portugal-specific annual direct costs of HCV health states were estimated by convening a panel of experts to derive health state resource use and multiplying the results by national unit costs. The model was developed from a healthcare system perspective with a timeframe corresponding to the remaining duration of the patients' lifetimes. Both future costs and QALYs were discounted at 5 %. To test the robustness of the conclusions, we conducted deterministic and probabilistic sensitivity analyses. RESULTS In comparison with the treatment with PR alone, boceprevir-based regimens were projected to reduce the lifetime incidence of advanced liver disease, liver transplantation, and liver-related death by 45-51 % and increase life expectancy by 2.3-4.3 years. Although the addition of BOC increased treatment costs by €13,300-€19,700, the reduction of disease burden resulted in a decrease of €5,400-€9,000 in discounted health state costs and an increase of 0.68-1.23 in discounted QALYs per patient. The incremental cost-effectiveness ratios of the boceprevir-based regimens compared with PR among previously untreated and previously treated patients were €11,600/QALY and €8,700/QALY, respectively. The results were most sensitive to variations in sustained virologic response rates, discount rates and age at treatment. CONCLUSIONS Adding boceprevir to PR was projected to reduce the number of liver complications and liver-related deaths, and to be cost effective in treating both previously untreated and treated patients.
