Abstract
Background Current German and European HIV guidelines recommend early evaluation of HCV treatment in all HIV/HCV co-infected patients. However, there are still considerable barriers to initiate HCV therapy in everyday clinical practice. This study evaluates baseline characteristics, “intention-to-treat” pattern and outcome of therapy of HCV/HIV co-infected patients in direct comparison to HCV mono-infected patients in a “real-life” setting. Methods A large, single-center cohort of 172 unselected HCV patients seen at the Infectious Diseases Unit at the University Medical Center Hamburg-Eppendorf from 2000–2011, 88 of whom HCV/HIV co-infected, was retrospectively analyzed by chart review with special focus on demographic, clinical and virologic aspects as well as treatment outcome. Results Antiviral HCV combination therapy with PEG-interferon plus weight-adapted ribavirin was initiated in 88/172 (52%) patients of the entire cohort and in n = 36 (40%) of all HCV/HIV co-infected patients (group A) compared to n = 52 (61%) of the HCV mono-infected group (group B) (p = 0.006). There were no significant differences of the demographics or severity of the liver disease between the two groups with the exception of slightly higher baseline viral loads in group A. A sustained virologic response (SVR) was observed in 50% (n = 18) of all treated HIV/HCV co-infected patients versus 52% (n = 27) of all treated HCV mono-infected patients (p = 0.859). Genotype 1 was the most frequent genotype in both groups (group A: n = 37, group B: n = 49) and the SVR rates for these patients were only slightly lower in the group of co-infected patients (group A: n = 33%, group B: 40% p = 0.626). During the course of treatment HCV/HIV co-infected patients received less ribavirin than mono-infected patients. Conclusion Overall, treatment was only initiated in half of the patients of the entire cohort and in an even smaller proportion of HCV/HIV co-infected patients despite comparable outcome (SVR) and similar baseline characteristics. In the light of newer treatment options, greater efforts to remove the barriers to treatment that still exist for a great proportion of patients especially with HIV/HCV co-infection have to be undertaken.

Abstract
BACKGROUND In HCV genotype 1-infected patients with HIV co-infection, tritherapy [HCV protease inhibitors (PIs) plus peg-interferon and ribavirin] has been shown to have an increased rate of sustained virological response. However, complex drug-to-drug interactions and tolerability issues remain a concern. METHODS Under the auspices of four French scientific societies of medicine, a committee was charged of establishing guidelines on the use of first-generation HCV PIs in these patients. This scientific committee based its work on preliminary results from tritherapy clinical trials in co-infected patients and, since data on these patients are still scarce, on the statements already made by the French Association for the Study of the Liver (AFEF) on the use of tritherapy in HCV mono-infected patients, written in May 2011 and updated in 2012. Each AFEF guideline concerning HCV monoinfection was examined to determine whether it could be used in the context of HIV/HCV coinfection. RESULTS These guidelines are addressed for the treatment of coinfected patients with various profiles, including treatment-naïve or patients with failure to previous bitherapy and mention those patients for whom tritherapy should start or those for whom it should be delayed. Preliminary results of triple therapy as well as factors associated to virological response are also discussed. Other issues include virological monitoring, clinical and virological criteria to stop therapy, practical treatment management, treatment adherence and the management of side effects and interactions with antiretroviral drugs. These guidelines were submitted for critical review to independent experts.

Abstract
There is scarce information about the impact of antiviral treatment on subsequent progression of liver fibrosis in HIV-infected patients with chronic hepatitis C who experience different outcomes following peginterferon-ribavirin therapy. We conducted a retrospective study of a cohort of HIV/HCV-coinfected patients with longitudinal assessment of liver fibrosis using elastometry. Patients were split out into four groups according to the prior peginterferon-ribavirin response: sustained virological response (SVR), relapse (R), partial response (PR) and null response (NR). A group of untreated, coinfected patients was taken as control. Significant liver fibrosis progression (sLFP) was defined as a shift from baseline Metavir estimates ≤ F2 to F3-F4, or by >30% increase in liver stiffness in patients with baseline F3-F4. Conversely, significant liver fibrosis regression (sLFR) was defined as a shift from baseline Metavir estimates F3-F4 to ≤ F2, or by >30% reduction in liver stiffness in patients that kept on F3-F4. A total of 498 HIV/HCV-coinfected patients were examined. They were classified as follows: 138 (27.7%) SVR, 40 (8%) R, 61 (12.2%) PR, 71 (14.3%) NR and 188 (37.8%) naive. After a mean follow-up of 53.3 months, sLFP occurred less frequently in patients with SVR (7.2%) compared with R (25%; P = 0.002), PR (23%; P = 0.002), NR (29.6%; P < 0.001) and naïve (19.7%; P = 0.002). Conversely, sLFR was 26.1% in SVR compared with 10% in R (P = 0.03), 14.8% in PR (P = 0.06), 16.9% in NR (P = 0.07) and 10.6% in naïve (P < 0.001). Sustained clearance of serum HCV-RNA following a course of antiviral treatment is the major determinant of liver fibrosis regression in HIV/HCV-coinfected patients.

Abstract
The incidence rate of hepatic decompensation was higher in patients with human immunodeficiency virus (HIV)/hepatitis B virus (HBV)/hepatitis C virus (HCV) triple infection than in those with HIV/HCV coinfection (24.1 vs 10.8 events per 1000 person-years; hazard ratio [HR], 1.89; 95% confidence interval [CI], 1.12-3.18). Compared with HIV/HCV-infected patients, the rate of decompensation was increased among HIV/HBV/HCV-infected patients receiving no anti-HBV therapy (HR, 2.48; 95% CI, 1.37-4.49) but not among those who did receive such therapy (HR, 1.09; 95% CI, .40-2.97).

Abstract
Co-infection with HIV and HCV is associated with accelerated progression of liver disease and increased complications compared with HCV infection alone. Treatment of HCV and achievement of a sustained virologic response (SVR) can improve outcomes in these patients. Even after clearance of the hepatitis C virus, however, patients remain at risk, albeit diminished, for the complications of chronic liver disease. As such, longitudinal monitoring of treated patients remains important for clinicians caring for this population. This article summarizes the benefits and persistent risks after attaining SVR. It reviews the natural history of fibrosis and addresses the monitoring and management of progressive liver disease.

Abstract
The estimated prevalence of hepatitis C virus (HCV) infection in India is between 0.5 and 1.5% with hotspots showing much higher prevalence in some areas of northeast India, in some tribal populations and in certain parts of Punjab. Genotype 3 is the most prevalent type of infection. Recent years have seen development of a large number of new molecules that are revolutionizing the treatment of hepatitis C. Some of the new directly acting agents (DAAs) like sofosbuvir have been called game-changers because they offer the prospect of interferon-free regimens for the treatment of HCV infection. These new drugs have not yet been approved in India and their cost and availability is uncertain at present. Till these drugs become available at an affordable cost, the treatment that was standard of care for the whole world before these newer drugs were approved should continue to be recommended. For India, cheaper options, which are as effective as the standard-of-care (SOC) in carefully selected patients, are also explored to bring treatment within reach of poorer patients. It may be prudent to withhold treatment at present for selected patients with genotype 1 or 4 infection and low levels of fibrosis (F1 or F2), and for patients who are non-responders to initial therapy, interferon intolerant, those with decompensated liver disease, and patients in special populations such as stable patients after liver and kidney transplantation, HIV co-infected patients and those with cirrhosis of liver.

Abstract
HCV and HIV co-infection is associated with accelerated hepatic fibrosis progression and higher rates of liver decompensation and death compared to HCV monoinfection, and liver disease is a leading cause of non-AIDS-related mortality among HIV-infected patients. New insights have revealed multiple mechanisms by which HCV and HIV lead to accelerated disease progression, specifically that HIV infection increases HCV replication, augments HCV-induced hepatic inflammation, increases hepatocyte apoptosis, increases microbial translocation from the gut and leads to an impairment of HCV-specific immune responses. Treatment of HIV with antiretroviral therapy and treatment of HCV have independently been shown to delay the progression of fibrosis and reduce complications from end-stage liver disease among co-infected patients. However, rates of sustained virologic response with PEG-IFN and ribavirin have been significantly inferior among co-infected patients compared with HCV-monoinfected patients, and treatment uptake has remained low given the limited efficacy and tolerability of current HCV regimens. With multiple direct-acting antiviral agents in development to treat HCV, a unique opportunity exists to redefine the treatment paradigm for co-infected patients, which incorporates data on fibrosis stage as well as potential drug interactions with antiretroviral therapy.

Abstract
BACKGROUND Few studies have explored how utilization of outpatient services differ for HIV/HCV coinfected patients compared to HIV or HCV monoinfected patients. The objectives of this study were to (1) compare annual outpatient clinic visit rates between coinfected and monoinfected patients, (2) to compare utilization of HIV and HCV therapies between coinfected and monoinfected patients, and (3) to identify factors associated with therapy utilization. METHODS Data were from the 2005-2010 U.S. National Hospital Ambulatory Medical Care Surveys. Clinic visits with a primary or secondary ICD-9-CM codes for HIV or HCV were included. Coinfection included visits with codes for both HIV and HCV. Monoinfection only included codes for HIV or HCV, exclusively. Patients <15 years of age at time of visit were excluded. Predictors of HIV and HCV therapy were determined by logistic regressions. Visits were computed using survey weights. RESULTS 3,021 visits (11,352,000 weighted visits) met study criteria for patients with HIV/HCV (8%), HIV (70%), or HCV (22%). The HCV subgroup was older in age and had the highest proportion of females and whites as compared to the HIV/HCV and HIV subgroups. Comorbidities varied significantly across the three subgroups (HIV/HCV, HIV, HCV): current tobacco use (40%, 27%, 30%), depression (32%, 23%, 24%), diabetes (9%, 10%, 17%), and chronic renal failure (<1%, 3%, 5%), (p < 0.001 for all variables). Annual visit rates were highest in those with HIV, followed by HIV/HCV, but consistently lower in those with HCV. HIV therapy utilization increased for both HIV/HCV and HIV subgroups. HCV therapy utilization remained low for both HIV/HCV and HCV subgroups for all years. Coinfection was an independent predictor of HIV therapy, but not of HCV therapy. CONCLUSION There is a critical need for system-level interventions that reduce barriers to outpatient care and improve uptake of HCV therapy for patients with HIV/HCV coinfection.

Abstract
BACKGROUND The incidence and determinants of hepatic decompensation have been incompletely examined among patients co-infected with HIV and hepatitis C virus (HCV) in the antiretroviral therapy (ART) era, and few studies have compared outcome rates with those of patients with chronic HCV alone. OBJECTIVE To compare the incidence of hepatic decompensation between antiretroviral-treated patients co-infected with HIV and HCV and HCV-monoinfected patients and to evaluate factors associated with decompensation among co-infected patients receiving ART. DESIGN Retrospective cohort study. SETTING Veterans Health Administration. PATIENTS 4280 co-infected patients who initiated ART and 6079 HCV-monoinfected patients receiving care between 1997 and 2010. All patients had detectable HCV RNA and were HCV treatment-naive. MEASUREMENTS Incident hepatic decompensation, determined by diagnoses of ascites, spontaneous bacterial peritonitis, or esophageal variceal hemorrhage. RESULTS The incidence of hepatic decompensation was greater among co-infected than monoinfected patients (7.4% vs. 4.8% at 10 years; P < 0.001). Compared with HCV-monoinfected patients, co-infected patients had a higher rate of hepatic decompensation (hazard ratio [HR] accounting for competing risks, 1.56 [95% CI, 1.31 to 1.86]). Co-infected patients who maintained HIV RNA levels less than 1000 copies/mL still had higher rates of decompensation than HCV-monoinfected patients (HR, 1.44 [CI, 1.05 to 1.99]). Baseline advanced hepatic fibrosis (FIB-4 score >3.25) (HR, 5.45 [CI, 3.79 to 7.84]), baseline hemoglobin level less than 100 g/L (HR, 2.24 [CI, 1.20 to 4.20]), diabetes mellitus (HR, 1.88 [CI, 1.38 to 2.56]), and nonblack race (HR, 2.12 [CI, 1.65 to 2.72]) were each associated with higher rates of decompensation among co-infected patients. LIMITATION Observational study of predominantly male patients. CONCLUSION Despite receiving ART, patients co-infected with HIV and HCV had higher rates of hepatic decompensation than HCV-monoinfected patients. Rates of decompensation were higher for co-infected patients with advanced liver fibrosis, severe anemia, diabetes, and nonblack race. PRIMARY FUNDING SOURCE National Institutes of Health.

Abstract
Sustained virologic response rates for hepatitis C virus are difficult to achieve in patients infected with human immunodeficiency virus, especially if they have other poor predictors of response. Rates of sustained virologic response for hepatitis C virus genotype 1 in patients with end stage kidney disease are lower than patients with normal renal function. We present the first case report of a co-infected African American man with end stage kidney disease, who was haemodialysis dependant, and an interferon non-responder with advanced liver fibrosis, who achieved sustained virologic response on a telaprevir-based regimen.

Abstract
Treating hepatitis C virus (HCV) in HIV/HCV co-infected patients is a challenge. Even if the benefits of achieving a sustained virological response are clear, the rates achieved with the combination of pegylated-interferon and ribavirin are disappointing. The addition of direct acting antiviral agents (DAAs) to the treatment of hepatitis C is revolutionizing the treatment of HCV in mono-infected patients. Even if there have not been any agents approved for the treatment of co-infected patients, many studies specifically designed for this population are ongoing. This article reviews available data on the use of DAAs in co-infected patients and the challenges associated with these new drugs.

Abstract
OBJECTIVES We examined HCV exposure prevalence and predictors among persons in the United States born during 1945-1965. METHODS With data from the 1999-2008 National Health and Nutrition Examination Survey, we calculated the proportion of persons born during 1945-1965 who tested positive for HCV antibody (anti-HCV) and analyzed the prevalence by sociodemographic and behavioral risk factors. RESULTS Anti-HCV prevalence in the 1945-1965 birth cohort was 3.2% (95% confidence interval [CI] = 2.8%, 3.8%), substantially higher than among other adults (0.9%). Within the cohort, anti-HCV prevalence was higher among non-Hispanic Blacks (6.4%; 95% CI = 5.3%, 7.7%), persons with injection drug use histories (56.8%; 95% CI = 48.4%, 64.8%), and persons with elevated alanine aminotransferase levels (12.7%; 95% CI = 10.7%, 15.1%). Injection drug use (adjusted odds ratio = 98.4; 95% CI = 58.8, 164.5) was the strongest anti-HCV prevalence predictor. Among anti-HCV-positive persons, 57.8% reported having 2 or more alcoholic drinks daily. CONCLUSIONS With the high prevalence of HCV among persons born during 1945-1965, the increasing morbidity and mortality associated with HCV, and reductions in liver cancer and HCV-related mortality when HCV is eradicated, it is critically important to identify persons with HCV and link them to appropriate care.

Abstract
A new transiently induced region (interferon-λ 4 protein; IFNL4) harbouring a dinucleotide variant ss469415590 (TT or ΔG), upstream of IFNL3 (IL28B), was recently found to be associated with hepatitis C virus (HCV) clearance. To determine the effect of IFLN4 ss469415590 variation on the HCV response to IFN-based therapy in HCV/HIV-1 coinfected patients, ss469415590 was genotyped in a cohort of 207 patients from our clinic. Treatment failure occurred in 77% of minor ΔG-allele carriers versus 48% of noncarriers, indicating that the ΔG allele was strongly associated with treatment failure. Importantly, multivariate logistic analysis revealed that ss469415590 genotype was a better predictor of treatment failure than rs12979860.

Abstract
In the United States, more than 1.1 million individuals are infected with the human immunodeficiency virus (HIV). These patients exhibit a high frequency of coinfections with other hepatotropic viruses and ongoing fibrosis, leading to cirrhosis and liver-related mortality. Etiologies of liver disease include viral hepatitis coinfections, drug-related hepatotoxicity, fatty liver disease, and direct and indirect effects from HIV infection, including increased bacterial translocation, immune activation, and presence of soluble proteins, that modulate the hepatic cytokine environment. New treatments for hepatitis C virus (HCV) using direct-acting agents appear viable, though issues related to intrinsic toxicities and drug-drug interactions remain. Recent research suggests that acute HCV infection, unrecognized hepatitis D infection, and hepatitis E may all represent emergent areas of concern. Antiretroviral agents, including those used in recent years, may represent risk factors for hepatic injury and portal hypertension. Key issues in the future include systematic implementation of liver disease management and new treatment in HIV-infected populations with concomitant injection drug use, alcohol use, and low socioeconomic status.

Chronic hepatitis C virus infection is associated with all-cause and liver-related mortality in a cohort of HIV-infected patients with alcohol problems. Addiction 2014; 109:62-70.

Abstract
AIMS To assess the association between hepatitis C virus (HCV) infection and overall and liver-related death in human immunodeficiency virus (HIV)-infected patients with alcohol problems. DESIGN We analyzed data from a cohort of HIV-infected adults with current or past alcohol problems enrolled between 2001 and 2003, searching for causes of death until 2010 using the National Death Index. SETTING AND PARTICIPANTS Participants were HIV-infected adults with current or past alcohol problems, recruited in Boston, MA from HIV clinics at two hospitals, homeless shelters, drug treatment programs, subject referrals, flyers and another cohort study with comparable recruitment sites. MEASUREMENTS The primary and secondary outcomes were all-cause and liver-related mortality, respectively. The main independent variable was hepatitis C virus (HCV) RNA status (positive versus negative). Mortality rates and Kaplan-Meier survival curves were calculated by HCV status for both overall and liver-related mortality. Cox proportional hazards models were used to assess the association between HCV infection and overall and liver-related death, adjusting for alcohol and drug use over time. FINDINGS A total of 397 adults (50% HCV-infected) were included. As of 31 December 2009, 83 cohort participants had died (60 HCV-infected, 23 HCV-uninfected; log-rank test P < 0.001), and 26 of those deaths were liver-related (21 HCV-infected, five HCV-uninfected; log-rank test P < 0.001). All-cause and liver-related mortality rates were 4.68 and 1.64 deaths per 100 person-years for HCV-infected patients and 1.65 and 0.36 per 100 person-years for those without HCV, respectively. In the fully adjusted Cox model, HCV infection was associated with both overall [hazard ratio (HR) = 2.55, 95% confidence interval (CI) = 1.50-4.33, P < 0.01], and liver-related mortality (HR = 3.24, 95% CI = 1.18-8.94, P = 0.02]. CONCLUSION Hepatitis C virus infection is associated independently with all-cause and liver-related mortality in human immunodeficiency virus-infected patients with alcohol problems, even when accounting for alcohol and other drug use.

Abstract
Evaluation of metabolic factors and elevated γ-glutamyltransferase (GGT) levels as independent predictors of treatment failure in a thoroughly documented cohort of HIV-/HCV-coinfected patients (HIV/HCV). Sixty-four HIV/HCV patients treated with pegylated interferon-α-2a plus ribavirin (PEGIFN + RBV) at the Medical University of Vienna within a prospective trial were included in this study. In addition, 124 patients with HIV/HCV from the AIFA-HIV and AHIVCOS cohorts were included as a validation cohort. Advanced liver fibrosis, GGT elevation, insulin resistance (IR) and low CD4+ nadir were defined as METAVIR F3/F4, GGT levels >1.5× sex-specific upper limit of normal, homoeostasis model assessment of insulin resistance >2 and CD4+ nadir <350 cells/μL, respectively. HCV-genotype 1/4 (OR26.3; P = 0.006), advanced liver fibrosis (OR20.2; P = 0.009), interleukin 28B rs12979860 non-C/C SNP (OR8.27; P = 0.02) and GGT elevation (OR7.97; P = 0.012) were independent predictors of treatment failure, while both IR (OR3.51; P = 0.106) and low CD4 + nadir (OR2.64; P = 0.263) were not independently associated with treatment failure. A statistically significant correlation between GGT elevation and prior alcohol abuse (r = 0.259; P = 0.039), liver steatosis (r = 0.301; P = 0.034) and low-density lipoprotein-cholesterol (r = -0.256; P = 0.041) was observed. The importance of GGT elevation as an independent predictor of treatment failure was confirmed in a validation cohort (OR2.76; P = 0.026). While GGT elevation emerged as an independent predictor of treatment failure in both the derivation and the validation cohort, no independent associations between metabolic factors and treatment failure were observed. Thus, our findings suggest that GGT elevation is an independent predictor of treatment failure in HIV/HCV that can easily be incorporated into predictive algorithms.

Abstract
BACKGROUND The aim of this study was to evaluate strategies for assignment of HIV-HCV genotype-1-coinfected patients (HIV-HCV-GT1) to either dual-therapy or direct-acting antiviral agent (DAA)-based triple-therapy. METHODS A total of 148 treatment-naive HIV-HCV-GT1 who received antiviral therapy with pegylated interferon/ribavirin were included in this multinational, retrospective analysis. Patients with rapid virological response (RVR) were treated for 48 weeks, while patients without RVR received either 48 or 72 weeks of treatment. IL28B rs12979860 (IL28B) non-C/C, advanced liver fibrosis and high HCV RNA were considered as established risk factors for treatment failure. RESULTS A trend toward higher sustained virological response (SVR) rates in patients with IL28B C/C (65% [37/57] versus 51% [40/79]; P=0.097) was observed. Higher SVR rates were observed in patients without advanced liver fibrosis (61% [47/77] versus 42% [22/52]); P=0.036) and without high HCV RNA (73% [35/48] versus 49% [49/100]; P=0.006), as well as in patients with RVR (90% [35/39] versus 45% [49/109]; P<0.001). SVR rates varied statistically significantly between the risk factors for treatment failure subgroups (86% [6/7] versus 69% [34/49] versus 48% [21/44] versus 20% [4/20] for zero, one, two and three risk factors, respectively; P<0.001). In patients without RVR, higher rates of SVR were observed in those treated for 72 weeks (62% [23/37]), when compared to patients treated for 48 weeks (36% [26/72]; P=0.01). CONCLUSIONS RVR had an excellent positive predictive value for the response to dual-therapy in HIV-HCV-GT1, emphasizing the utility of a lead-in phase for assigning these patients to dual-therapy or DAA-based triple-therapy. The use of an IL28B-guided approach was suboptimal, while a combination of established baseline predictors may provide guidance for individual treatment decisions prior to the initiation of antiviral therapy. However, the extension of treatment duration to 72 weeks in HIV-HCV-GT1 without RVR should be strongly considered if triple-therapy is not available.

Abstract
Despite the major advances in the management of HIV infection, HIV-infected patients still have greater morbidity and mortality than the general population. Serious non-AIDS events (SNAEs), including non-AIDS malignancies, cardiovascular events, renal and hepatic disease, bone disorders and neurocognitive impairment, have become the major causes of morbidity and mortality in the antiretroviral therapy (ART) era. SNAEs occur at the rate of 1 to 2 per 100 person-years of follow-up. The pathogenesis of SNAEs is multifactorial and includes the direct effect of HIV and associated immunodeficiency, underlying co-infections and co-morbidities, immune activation with associated inflammation and coagulopathy as well as ART toxicities. A number of novel strategies such as ART intensification, treatment of co-infection, the use of anti-inflammatory drugs and agents that reduce microbial translocation are currently being examined for their potential effects in reducing immune activation and SNAEs. However, currently, initiation of ART before advanced immunodeficiency, smoking cessation, optimisation of cardiovascular risk factors and treatment of HCV infection are most strongly linked with reduced risk of SNAEs or mortality. Clinicians should therefore focus their attention on addressing these issues prior to the availability of further data.

Abstract
There are few data about the long-term histological outcome of HIV-/HCV-coinfected patients after therapy with interferon and ribavirin. We performed an observational study of 216 patients who received therapy against HCV and who had at least three successive transient elastographies (TE) during the follow-up. The primary endpoint was confirmed fibrosis regression, defined as a reduction of at least 1 point in Metavir fibrosis score, confirmed and without worsening in successive TE. At baseline, 23% had fibrosis stage 4 or cirrhosis. Overall, 82 (38%) achieved sustained virological response (SVR), without differences in baseline fibrosis or time of follow-up. Confirmed fibrosis regression was observed in 55% of patients, higher for SVR (71% vs 44%; P < 0.01), and the likelihood of achieving fibrosis regression at 3, 5 and 7 years was 0.17, 0.51 and 0.67, respectively, for SVR patients, in comparison with 0.02, 0.23 and 0.41 for no SVR patients (P < 0.01, log-rank test at any time point). Progressive regression, defined as continuous improvement in successive TE, was observed in 62% of patients with advanced liver fibrosis or cirrhosis who achieved SVR. In a Cox regression model, only SVR (HR, 4.01; 95% CI, 2.33-7.57; P < 0.01) and a younger age (HR, 1.14; 95% CI, 1.05-1.25; P < 0.01; per year) were associated with fibrosis regression. This study confirms that the rate of liver fibrosis regression increases during the follow-up after SVR to interferon therapy in HIV-/HCV-coinfected patients.

Abstract
Hepatitis C (HCV) coinfection is the leading cause of liver-related morbidity and is a leading cause of mortality in human immunodeficiency virus (HIV)-infected individuals in the antiretroviral therapy era. Direct-acting antiviral (DAA) therapies are transforming how HCV is treated with significant improvements in efficacy and tolerability. In this article, DAA agents expected to be available in 2014 are reviewed, including telaprevir, boceprevir, sofosbuvir, simeprevir, faldaprevir, and daclatasvir. Available data regarding clinical efficacy, adverse effects, and drug interactions in HIV-HCV coinfection are discussed. The management of adverse effects of HCV therapy and treatment considerations in patients with cirrhosis are also reviewed.

Abstract
OBJECTIVES The aim of the study was to assess the progression of liver fibrosis in HIV/hepatitis C virus (HCV)-coinfected patients with no or mild-to-moderate fibrosis (stages F0-F2). METHODS Liver fibrosis was reassessed by transient elastometry (TE) between January 2009 and November 2011 in HIV/HCV-coinfected patients with stage F0-F2 fibrosis in a liver biopsy performed between January 1997 and December 2007. Patients with liver stiffness at the end of follow-up < 7.1 kPa were defined as nonprogressors, and those with values ≥ 9.5 kPa or who died from liver disease were defined as progressors. Cirrhosis was defined as a cut-off of 14.6 kPa. The follow-up period was the time between liver biopsy and TE. Cox regression models adjusted for age, gender and liver fibrosis stage at baseline were applied. RESULTS The median follow-up time was 7.8 years [interquartile range (IQR) 5.5-10 years]. The study population comprised 162 patients [115 (71%) nonprogressors and 47 (29%) progressors; 19 patients (11.7%) had cirrhosis]. The median time from the diagnosis of HCV infection to the end of follow-up was 20 years (IQR 16.3-23.1 years). Three progressors died from liver disease (1.8%). The variables associated with a lower risk of progression were age ≤ 38 years (hazard ratio (HR) 0.32; 95% confidence interval (CI) 0.16-0.62; P = 0.001], having received interferon (HR 2.18; 95% CI 1.14-4.15; P = 0.017), being hepatitis B virus surface antigen (HBsAg) negative (HR 0.20; 95% CI 0.04-0.92; P = 0.039), and baseline F0-F1 (HR 0.43; 95% CI 0.28-0.86; P = 0.017). CONCLUSIONS A high proportion of patients with stage F0-F2 fibrosis progress to advanced liver fibrosis. Advanced liver fibrosis must be included in the list of diseases associated with aging. Our results support the recommendation to offer HCV antiviral therapy to HIV/HCV-coinfected patients at early stages of liver fibrosis.

Abstract
Despite modern effective HIV treatment, hepatitis C virus (HCV) co-infection is associated with a high risk of progression to end-stage liver disease (ESLD) which has emerged as the primary cause of death in this population. Clinical interest lies in determining the impact of clearance of HCV on risk for ESLD. In this case study, we examine whether HCV clearance affects risk of ESLD using data from the multicenter Canadian Co-infection Cohort Study. Complications in this survival analysis arise from the time-dependent nature of the data, the presence of baseline confounders, loss to follow-up, and confounders that change over time, all of which can obscure the causal effect of interest. Additional challenges included non-censoring variable missingness and event sparsity. In order to efficiently estimate the ESLD-free survival probabilities under a specific history of HCV clearance, we demonstrate the double-robust and semiparametric efficient method of Targeted Maximum Likelihood Estimation (TMLE). Marginal structural models (MSM) can be used to model the effect of viral clearance (expressed as a hazard ratio) on ESLD-free survival and we demonstrate a way to estimate the parameters of a logistic model for the hazard function with TMLE. We show the theoretical derivation of the efficient influence curves for the parameters of two different MSMs and how they can be used to produce variance approximations for parameter estimates. Finally, the data analysis evaluating the impact of HCV on ESLD was undertaken using multiple imputations to account for the non-monotone missing data.

Abstract
OBJECTIVE According to the European AIDS Clinical Society (EACS) guidelines for response-guided therapy (RGT) of chronic hepatitis C virus (HCV) infection in HIV-positive patients, HCV-genotype (GT) and rapid virologic response (RVR) exclusively determine the duration of antiviral therapy with pegylated interferon and ribavirin (PEGIFN+RBV). The aim of this study was to investigate the impact of interleukin 28B rs12979860 single nucleotide polymorphism (IL28B) and liver fibrosis stage on RGT in HIV/HCV-coinfected patients. DESIGN Four hundred and thirty HIV/HCV-coinfected patients treated with PEGIFN+RBV were included in this multinational, retrospective analysis. METHODS Advanced liver fibrosis was defined as either METAVIR F3/F4 or liver stiffness more than 9.5 kPa. RESULTS In patients with GT1/4 without RVR (GT1/4-noRVR), higher sustained virologic response (SVR) rates were observed in patients with extended treatment duration (48 weeks: 35% vs. 72 weeks: 60%; P = 0.008). In GT1/4-noRVR patients without advanced liver fibrosis (48 weeks: 45% vs. 72 weeks: 61%; P = 0.176), or with IL28B C/C (48 weeks: 48% vs. 72 weeks: 69%; P = 0.207), SVR rates did not vary significantly throughout the treatment duration subgroups. In contrast, in patients with advanced liver fibrosis (48 weeks: 11% vs. 72 weeks: 45%; P = 0.031), or IL28B non-C/C (48 weeks: 28% vs. 72 weeks: 56%; P = 0.011), extended treatment duration was associated with substantially higher SVR rates. GT2/3 patients with RVR (GT2/3-RVR) with shortened treatment duration (24 weeks) displayed SVR rates ranging from 83 to 100%, regardless of IL28B and liver fibrosis stage. CONCLUSION Our study confirms the concept of RGT in HIV/HCV coinfection and supports the extension of therapy duration to 72 weeks for patients with GT1/4-noRVR, especially in patients with IL28B non-C/C or advanced liver fibrosis. The results of our study strongly support the shortening of therapy duration to 24 weeks in GT2/3-RVR patients, regardless of IL28B and advanced liver fibrosis.

Abstract
Antiretroviral-related hepatotoxicity occurs commonly in patients with human immunodeficiency virus (HIV). Liver injury ranges from unconjugated hyperbilirubinemia and nodular regenerative hyperplasia to lactic acidosis and toxic hepatitis. Effective antiretroviral therapy has changed coinfected patients' primary morbidities and mortality to chronic liver disease rather than complications from HIV. Treatment for hepatitis C virus (HCV) is strongly encouraged early in all coinfected patients. However, drug-drug interactions must be considered to ensure safe and tolerable use alone or in combination with antiretroviral therapies. The first-generation and newer HCV direct-acting antivirals are promising in coinfected patients, with minimal side effects and hepatotoxicity.

Abstract
Morbidity and mortality from co-morbid hepatitis C (HCV) infection in HIV co-infected patients are increasing; hence, the management of hepatitis co-infection in HIV is now one of the most important clinical challenges. Therefore, the development of direct acting antivirals (DAAs) for treatment of HCV has been eagerly awaited to hopefully improve HCV treatment outcome in co-infected individuals. Indeed, the availability of the first HCV protease inhibitors (PI) boceprevir and telaprevir for HCV genotype 1 patients has changed the gold standard of treating hepatitis C allowing for substantially improved HCV cure rates under triple HCV-PI/pegylated interferon/ribavirin therapy. Moreover, numerous other new DAAs are currently being studied in co-infected patient populations, also exploring shorter treatment durations and interferon-free treatment approaches promising much easier and better tolerated treatment regimens in the near future. Nevertheless, numerous challenges remain, including choice of patients to treat, potential for drug-drug interactions and overlapping toxicities between HIV and HCV therapy. The dramatically improved rates of HCV cure under new triple therapy, however, warrant evaluation of these new treatment options for all co-infected patients.

Abstract
Liver disease is currently one of the leading causes of hospitalization and death in HIV-positive individuals. Coinfection with the hepatitis C virus (HCV) is a major contributor to this trend. Besides hepatic damage, which is enhanced in the presence of HIV-associated immunosuppression, HCV may contribute to disease in coinfected individuals by potentiating immune activation and chronic inflammation, which ultimately account for an increased risk of cardiovascular events, kidney disease, and cancers in this population. Fortunately, hepatitis C therapeutics has entered a revolutionary era in which we hope that most patients treated with the new oral direct-acting antivirals (DAA) will be cured. However, many challenges preclude envisioning a prompt elimination of HCV from the coinfected population. Issues that should be addressed include the following: (1) rising incidence of acute hepatitis C in men who have sex with men, and expansion/recrudescence of injection drug use in some settings/regions; (2) adverse drug interactions between antiretrovirals and DAA; and (3) high cost of DAA, which may lead many to defer or fail to access appropriate therapy.

Abstract
Hepatitis C virus (HCV) treatment is rapidly changing but little is known about patients' attitudes and knowledge about HCV. This study used a cross-sectional survey to examine the relationship between HCV knowledge and attitudes towards HCV in patients with HCV mono-infection and HIV/HCV co-infection. Subsequently, an education intervention was developed with an abridged version of the cross-sectional survey administered before and after the education session to assess changes in knowledge and attitudes. 292 people participated in the cross-sectional survey, and 87 people participated in the education intervention. In the cross-sectional survey, the mean knowledge score regarding HCV was low (<50% of the total possible score). Mono-infected and co-infected individuals shared similar knowledge deficits and attitudes towards HCV despite having distinct demographic differences. Attitudes endorsed by patients included the following: 57% feared the consequences of HCV on their life, 37% felt HCV was not fatal, 27% did not believe they needed HCV medication, 21% felt ashamed of having HCV and 16% felt HCV treatment was not important. Attitudes that reflected indifference and shame towards HCV were associated with lower knowledge scores (HCV knowledge score of 15.1 vs. 17.5, P < 0.01 for indifference and 15.3 vs. 17.2 for shame, P = 0.02). The education intervention improved knowledge scores but did not modify the assessed attitudes. Intervention studies are needed to effectively change attitudes towards HCV infection and treatment.

Abstract
We are entering an important new chapter in the story of hepatitis C virus (HCV) infection. There are clear challenges and opportunities. On the one hand, new HCV infections are still occurring, and an estimated 185 million people are or have previously been infected worldwide. Most HCV-infected persons are unaware of their status yet are at risk for life-threatening diseases such as cirrhosis and hepatocellular carcinoma (HCC), whose incidences are predicted to rise in the coming decade. On the other hand, new HCV infections can be prevented, and those that have already occurred can be detected and treated--viral eradication is even possible. How the story ends will largely be determined by the extent to which these rapidly advancing opportunities overcome the growing challenges and by the vigor of the public health response.

Abstract
BACKGROUND Uptake of treatment for hepatitis C virus (HCV) is low in Canada despite its publicly funded health care system. We explored the uptake of HCV treatment within the Canadian Co-infection Cohort to determine if some treatment centres have been more successful than others at starting patients with HIV-HCV coinfection on HCV treatment. METHODS We estimated the variation between 16 centres in the uptake of HCV treatment using a Weibull time-to-event model with adjustment for patient characteristics that are thought likely to influence the uptake of treatment. We asked the principal investigator at each centre about access to hepatitis-related specialists and services and the importance of various criteria when determining if a patient with HIV-HCV coinfection should receive treatment for HCV. RESULTS Among 681 untreated patients in the Canadian Co-infection Cohort, 163 patients with HIV-HCV coinfection started HCV treatment over a period of 1827 patient-years (9 per 100 patient-years). Even after adjustment for case mix, there was still appreciable variation in treatment uptake between centres, with mean hazard ratios of 0.43 (95% credible interval 0.11-1.3) and 3.6 (95% credible interval 1.7-8.4) for the centres least and most likely to start an average patient with HIV-HCV coinfection on HCV treatment. The most important criteria reported by principal investigators for determining eligibility for treatment were severity of fibrosis, current psychiatric comorbidities, current alcohol intake, past HCV treatment and a history of reinfection with HCV. However, the opinions were wide-ranging: 8 of the 15 criteria elicited both the responses "less important" and "very important." INTERPRETATION The magnitude of the centre effects and diverse opinions about the importance of treatment eligibility criteria suggest that provider-related barriers to HCV treatment uptake are as important as patient-related barriers.

Abstract
Where active antiretroviral therapy (ART) is accessible, human immunodeficiency virus (HIV) is a survivable illness and effective ART can reduce HIV transmission. Chronic hepatitis C virus (HCV) has emerged as a threat to the survival of individuals harboring both HCV and HIV, due to high prevalence and aggressive disease course. The HCV/HIV coinfection epidemic has been driven by people who inject drugs (PWID), although incident HCV is rising among HIV-infected men who have sex with men in the absence of drug injection. Coinfected individuals warrant aggressive treatment of both viruses; although early ART initiation is recommended to reduce the rate of liver disease progression, the most effective way to decrease HCV-related morbidity and mortality in coinfection is to achieve HCV viral eradication. Direct-acting antiviral (DAA) agents will soon revolutionize HCV treatment. Clinical data are needed regarding the efficacy of DAAs in coinfected PWID. Drug-drug interaction studies between ART, DAAs, and opiate substitution therapy must be expedited. Coinfected PWID should have equitable and universal access to HIV/AIDS, HCV, and addiction prevention, care, and treatment. Essential basic steps include improving screening for both infections and engaging coinfected PWID in HIV and HCV care early after diagnoses. Developing strategies to expand access to HCV therapy for coinfected PWID is imperative to stem the HCV epidemic and limit the morbidity and mortality of those at greatest risk for HCV disease progression. The ultimate goal must be the elimination of HCV from all coinfected PWID.

Abstract
BACKGROUND Among patients with hepatitis C virus (HCV) monoinfection, 25-hydroxyvitamin D [25(OH)D] concentrations are positively associated with a response to peg-interferon/ribavirin. Data on the relation between 25(OH)D concentrations and HCV treatment response in HIV-infected patients are limited. OBJECTIVE The objective was to determine whether baseline 25(OH)D concentrations predict virologic response in HIV/HCV co-infected patients and to examine variables associated with 25(OH)D concentrations ≥30 ng/mL. DESIGN Data and samples from 144 HCV genotype 1, treatment-naive patients from a completed HCV treatment trial were examined in this retrospective study. Early virologic response (EVR) was defined as ≥2 log10 reduction in HCV RNA and/or HCV RNA <600 IU/mL at week 12 of peg-interferon/ribavirin treatment. Baseline 25(OH)D was measured by liquid chromatography/tandem mass spectrometry. RESULTS Compared with the non-EVR control group (n = 68), the EVR group (n = 76) was younger, had fewer cirrhotic subjects, had a higher proportion with the IL28B CC genotype, had a higher albumin concentration, and had a lower HCV viral load at baseline (P ≤ 0.05). The difference in baseline 25(OH)D concentrations between EVR and non-EVR patients was not statistically significant (median: 25 ng/mL compared with 20 ng/mL; P = 0.23). Similar results were found for sustained virologic response (SVR). In multivariable analysis, white and Hispanic race-ethnicity (OR: 6.26; 95% CI: 2.47, 15.88; P = 0.0001) and ritonavir use (OR: 2.68; 95% CI: 1.08, 6.65; P = 0.033) were associated with higher 25(OH)D concentrations (≥30 ng/mL). CONCLUSION Baseline 25(OH)D concentrations did not predict EVR or SVR. Because ritonavir impairs the conversion of 25(OH)D to the active metabolite, utilization of 25(OH)D may have been impaired in subjects taking ritonavir. This trial was registered at www.clinicaltrials.gov as NCT00078403.

Abstract
BACKGROUND & AIMS The influence of HCV-RNA levels and genotype on HCV disease progression is not well studied. The prognostic value of these markers was investigated in HIV/HCV co-infected individuals from the EuroSIDA cohort. METHODS EuroSIDA is a prospective cohort of 18,295 HIV-1 infected patients in 105 centres across Europe, Israel, and Argentina. All subjects with known HCV antibody (HCVAb) status (n=13,025) were enrolled in the present study. RESULTS 4044 (31.0%) patients had detectable HCVAb. After adjustment, HCVAb+ patients had an increased incidence of liver-related death (LRD) compared to HCVAb- individuals (IRR 8.90; 95% CI 5.60-14.14, p<0.0001). Information on HCV-RNA was available for 2709 (67.0%) HCVAb+ patients and 2010 (74.2%) were HCV-RNA+. Of 1907 patients with measured HCV genotype, 1008 (52.9%), 62 (3.3%), 567 (29.7%), and 270 (14.2%) were infected with genotype 1, 2, 3 and 4, respectively. Patients with detectable HCV-RNA had similar incidence of non-LRD, but higher incidence of LRD compared to HCVAb+ aviremic patients (adjusted IRR 1.18; 95% CI 0.93-1.50, p=0.17) and (adjusted IRR 2.11; 95% CI 1.30-3.42, p=0.0025), respectively. In patients with HCV viremia, HCV-RNA levels and HCV genotype did not influence the risk of non-LRD or LRD. CONCLUSIONS HCV seropositive HIV patients had a 9-fold increased risk of LRD compared to patients who were HCV seronegative. Risk of death from any cause or LRD was not influenced by level of HCV viremia or HCV genotype.

Abstract
Hepatitis C virus (HCV) infection is the most common etiology of chronic liver disease in Western countries. Morbidity and mortality due to HCV-related end-stage liver disease are increasing, just as novel therapeutics arrive with the promise of better cure rates that prevent these complications. However, substantial barriers to successful application of these novel treatments remain, including the lack of providers with sufficient knowledge to address this epidemic. To address these deficits, this article aims to provide a general framework with algorithms to guide initial management decisions for HCV genotype 1 infection, the most commonly found genotype, based on therapies approved as of 2013.

Abstract
Hepatitis C virus (HCV) and human immunodeficiency virus (HIV) share a common route of transmission so that about one third of HIV infected individuals show HCV co-infection. Highly active antiretroviral therapy has offered a longer and better life to infected patients. While has removed AIDS-related diseases from the list of most common causes of death their place has been taken by complications of HCV infection, such as cirrhosis, end stage liver disease and hepatocellular carcinoma (HCC). HIV/HCV co-infection requires complex management, especially when HCC is present. Co-infected patients with HCC undergo the same therapeutic protocol as their mono-infected counterparts, but special issues such as interaction between regimens, withdrawal of therapy and choice of immunosuppressive agents, demand a careful approach by specialists. All these issues are analyzed in this minireview.

Abstract
BACKGROUND Rates of sustained virological response (SVR) to peginterferon-ribavirin are low in patients with hepatitis C virus (HCV) genotype 1 and HIV. We aimed to assess efficacy and safety of triple therapy with boceprevir plus pegylated interferon alfa-2b (peginterferon) and ribavirin, which increases rates of SVR in patients with HCV alone. METHODS In our double-blind, randomised controlled phase 2 trial, we enrolled adults (18-65 years) with untreated HCV genotype 1 infection and controlled HIV (HIV RNA <50 copies per mL) at 30 academic and non-academic study sites. We randomly allocated patients (1:2) according to a computer generated sequence, stratified by Metavir score and baseline HCV RNA level, to receive peginterferon 1·5 μg/kg per week with weight-based ribavirin (600-1400 mg per day) for 4 weeks, followed by peginterferon-ribavirin plus either placebo (control group) or 800 mg boceprevir three times per day (boceprevir group) for 44 weeks. Non-nucleoside reverse-transcriptase inhibitors, zidovudine, and didanosine were not permitted. The primary efficacy endpoint was SVR (defined as undetectable plasma HCV RNA) at follow-up week 24 after end of treatment. We assessed efficacy and safety in all patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, number NCT00959699. FINDINGS From Jan 15, 2010, to Dec 29, 2010, we enrolled 99 patients, 98 of whom received at least one treatment dose. 40 (63%) of 64 patients in the boceprevir group had an SVR at follow-up week 24, compared with ten (29%) of 34 control patients (difference 33·1%, 95% CI 13·7-52·5; p=0·0008). Adverse events were more common in patients who received boceprevir than in control patients: 26 (41%) versus nine (26%) had anaemia, 23 (36%) versus seven (21%) pyrexia, 22 (34%) versus six (18%) decreased appetite, 18 (28%) versus five (15%) dysgeusia, 18 (28%) versus five (15%) vomiting, and 12 (19%) versus two (6%) neutropenia. Three patients who received boceprevir plus peginterferon-ribavirin and four controls had HIV virological breakthrough. INTERPRETATION Boceprevir in combination with peginterferon-ribavirin could be an important therapeutic option for patients with HCV and HIV. FUNDING Merck.

Abstract
BACKGROUND & AIMS Sustained viral response (SVR) after therapy with interferon-ribavirin (IF-RB) reduces liver-related (LR) complications and mortality in HIV/HCV-co-infected patients. Here, we assess the impact of end-of-treatment response with subsequent relapse (REL) on LR events (LR death, liver decompensation, hepatocellular carcinoma, or liver transplantation), and liver stiffness (LS) by transient elastography. METHODS We analyzed the GESIDA 3603 Cohort (HIV/HCV-co-infected patients treated with IF-RB in 19 centers in Spain). Response to IF-RB was categorized as SVR, REL, and no response (NR). The study started when IF-RB was stopped and ended at death or the last follow-up visit. Multivariate regression analyses were adjusted for age, sex, HIV category of transmission, CDC clinical category, nadir CD4+ cell count, HCV genotype, HCV-RNA viral load, and liver fibrosis. RESULTS Of 1599 patients included, response was categorized as NR in 765, REL in 250 and SVR in 584. Median follow-up was more than 4 years in each group. Taking the group of patients with NR as reference, we found that the adjusted hazard ratios (95% confidence interval) of liver-related events (liver-related death, liver decompensation, hepatocellular carcinoma, liver transplantation) for patients with REL and for patients with SVR were 0.17 (0.05; 0.50) and 0.03 (0; 0.20), respectively. We also found that SVR was followed by less liver stiffness than both REL and NR. However, REL was associated with less liver stiffness than NR. CONCLUSIONS Best outcomes were achieved with an SVR. However, REL was associated with less LR mortality, decompensation, and liver stiffness than NR.

Abstract
BACKGROUND Chronic hepatitis C virus (HCV) infection has become a leading cause of non-acquired immunodeficiency syndrome (AIDS)-related morbidity and mortality for human immunodeficiency virus (HIV)-infected persons in the highly active antiretroviral therapy (HAART) era. Despite injection drug use (IDU) remaining the main route of HCV infection, recent reports indicate outbreaks of acute HCV infection among HIV-infected men who have sex with men (MSM) and sexually transmitted infections in the absence of IDU. METHODS We conducted a retrospective observational study of behavioural and demographic factors of patients with and without incident HCV infection among HIV-infected individuals followed at the AIDS Clinic of the Infectious Disease Department of the University of Ancona from 1989 to 2011. RESULTS Overall, 440 patients were considered; a total of 145 patients had initial positive HCV antibody test results (HCV+); a total of 295 patients had initial negative HCV antibody test results (HCV-). In the latter population, 14 seroconverted to HCV antibody (neoHCV), with an overall incidence of 0.59 per 100 person-years. While IDU was the principal risk factor of HCV+, the main route of transmission of incident HCV infection was sexual transmission. The HCV- group was significantly older than the other two groups and showed a significantly lower CD4 count at HIV diagnosis than neoHCV. Being Italian and having a low level of education were significantly more represented in HCV+. Younger age at HIV infection, IDU and additional risk factors other than sexual transmission significantly affected the probability of being HCV+. The cumulative probability of developing HCV infection in the HCV- group was calculated to be 6% at 15 years. CONCLUSIONS The epidemiology of the newly acquired HCV in HIV+ persons is changing. Therefore, a frequent and constant counselling about HCV infection is desirable and a periodical screening test is mandatory.

Abstract
Hepatitis C virus (HCV) and HIV are common coinfections that convey a shortened lifespan, mostly related to liver disease. Treatment against HCV in the coinfected patient is notoriously more complex and challenging. There are no optimal treatment algorithms for HIV/HCV coinfected patients as efficacy of approved anti-HCV therapies is low with relevant side effects. The use of direct-acting antivirals for anti-HCV therapy has the potential to improve therapeutic efficacy, but also increase side effects and drug-drug interactions. In spite of all of this, the most important and significant fact is that chronic hepatitis C is potentially curable, and the eradication of the HCV infection is a crucial outcome in this population. The establishment of a productive collaboration among the regulatory agencies, the medical community and the pharmaceutical industry could lead to faster access to more effective HCV therapies for the coinfected patient and eventually stop the progression of liver disease in these patients.

Abstract
PURPOSE OF REVIEW Successful treatment of hepatitis C virus (HCV) infection is necessary for the survival of HIV-infected patients. This review covers the outcomes of current therapy, first-generation HCV direct-acting antivirals (DAAs) and their drug-to-drug interactions (DDIs). Understanding DDIs between HIV antiretroviral therapy (ART) and the DAAs in development is important to assure the best management of the HIV/HCV coinfected individuals. RECENT FINDINGS The two first-in-class DAAs were approved for clinical use in 2011. The first trials with boceprevir or telaprevir added to standard therapy in HIV/HCV coinfected patients revealed triple therapy to be efficacious with significantly improved sustained virological response rates. However, these DAAs were associated with more and worse adverse effects, as well as with significant DDIs with multiple drugs, including ART. Early data on DAAs in development suggest improved efficacy and safety and the potential for lesser DDIs. SUMMARY Anti-HCV therapy is fundamental in coinfected patients, but the approved therapies are suboptimal. The first-generation of approved HCV DAAs improved efficacy of therapy in coinfected patients, but have multiple safety concerns, including potentially serious drug interactions with ART. Early results from newer DAAs are promising.

Abstract
BACKGROUND HCV virus (HCV) is a significant global problem with wide-ranging socio-economic impacts. Because of the high morbidity and mortality associated with end-stage liver disease, cirrhosis, and hepatocellular carcinoma (HCC), the economic burden of HCV infection is substantial. OBJECTIVES This study aimed to estimate the direct medical care costs of chronic HCV infection. PATIENTS AND METHODS For this cross-sectional study, 365 courses of HCV treatment were extracted from medical records of 284 patients being referred to Tehran HCV clinic, a clinical clinic of Baqiyatallah Research Center for Gastroenterology and Liver diseases, from 2005 to 2010. All the patients had been diagnosed with HCV. Direct medical care costs for each course of HCV treatment have been calculated based on Purchasing Power Parity Dollar (PPP$). RESULTS Average direct medical costs for the courses treated with conventional interferon plus ribavirin (INF-RBV) were 4,403 PPP$, and 20,010 PPP$ for peg-interferon plus ribavirin (PEG-RBV) courses. There was an increase of the direct costs in both courses of treatment to achieve Sustain Viral Response (SVR). The costs amounted to 10,072 PPP$ in (INF-RBV) treatment and 34,035 PPP$ in (PEG-RBV). The significant difference between the costs of these two courses of treatment is attributable to high cost of Peg-interferon. This indicates that the medication costs are the dominant costs. CONCLUSIONS According to the results, total direct medical costs for HCV patients in Iran exceeded 12 billion PPP$ in (INF-RBV) treatment and 55 billion PPP$ in (PEG-RBV).

Abstract
BACKGROUND Liver disease is currently one of the leading causes of death in HIV individuals. Hepatic fibrosis largely mediates this effect and infection with hepatitis C virus (HCV) is the most common cause. Few studies have examined so far the predictive value of liver fibrosis staging on mortality and liver decompensation in HIV/HCV-coinfected patients. METHODS A prospective programme of liver fibrosis assessment using transient elastometry has been ongoing at our institution since 2004. Data from all HIV/HCV-coinfected patients who underwent a transient elastometry examination and have at least 18 months of follow-up were selected for the current analysis. RESULTS A total of 545 HIV/HCV-coinfected patients were examined (mean age 41 years, 71% men, 81% IDUs, mean BMI 23.3 kg/m2, HBsAg+ 4.2%, alcohol abuse 8.4%, mean CD4 cell count 519 cells/μl). The mean follow-up was 70.9 ± 15.7 months. During follow-up, 12 patients (2.2%) died, four of them due to hepatic complications. Liver-related events (ascites, encephalopathy, oesophageal varices or hepatocellular carcinoma) appeared in 53 patients (10%). In the multivariate analysis, baseline liver stiffness was the strongest predictor of liver-related complications [odds ratio (OR) 1.12, 95% confidence interval (CI) 1.08-1.16, P < 0.0001] and of all-cause mortality (OR 1.09, 95% CI 1.01-1.19, P = 0.02). The achievement of sustained virological response following peginterferon/ribavirin therapy during the study period was protective against the development of liver-related events (OR 0.02, 95% CI 0-0.23, P = 0.01). CONCLUSION Liver fibrosis staging, as measured by transient elastometry, predicts liver-related complications and all-cause mortality in HIV/HCV-coinfected patients on antiretroviral therapy.

Abstract
OBJECTIVES Buprenorphine is associated with enhanced human immunodeficiency virus (HIV) treatment outcomes including increased antiretroviral therapy initiation rates, adherence, and CD4 cell counts among HIV-infected opioid-dependent individuals. Buprenorphine facilitates hepatitis C virus (HCV) treatment in opioid-dependent patients with HCV monoinfection. Less is known about buprenorphine's role in HIV/HCV coinfection. METHODS We conducted a retrospective chart review to evaluate HCV care for HIV-infected buprenorphine patients in the first 4 years of buprenorphine's integration into a Rhode Island HIV clinic. RESULTS Sixty-one patients initiated buprenorphine. All had HCV antibody testing; 57 (93%) were antibody-positive. All antibody-positive patients underwent HCV RNA testing; 48 (84%) were RNA-positive. Of these, 15 (31%) were not referred to HCV care. Among chronically infected patients, 3 received HCV treatment after buprenorphine; all had cirrhosis and none achieved viral eradication. At buprenorphine induction, most patients had inadequately controlled HIV infection, with detectable HIV RNA (59%) or CD4 cell count less than or equal to 350/μL (38%). CONCLUSIONS Buprenorphine has shown limited success to date as a bridge to HCV treatment within an HIV clinic. Buprenorphine's stabilization of opioid dependence and HIV disease may permit the use of HCV therapy over time.

Abstract
BACKGROUND The objective of this study was to determine the impact of sustained virologic response (SVR) to pegylated interferon (peg-IFN) plus ribavirin (RBV) on the incidence of liver-related complications and overall mortality in human immunodeficiency virus (HIV)-infected patients with compensated hepatitis C virus (HCV)-related cirrhosis. METHODS We included in this prospective cohort study 166 coinfected patients with compensated cirrhosis, who received peg-IFN plus RBV, to assess the time from the starting date of HCV therapy to the first hepatic decompensation and death due to any cause. RESULTS SVR was observed in 43 (25%) individuals. Two (4.6%) patients with SVR developed liver decompensation vs 33 (26.8%) individuals without SVR (P = .002). The incidence of liver-related complications was 0.89 cases per 100 person-years (95% confidence interval [CI], .11-3.1) in SVR patients and 6.4 cases per 100 person-years (95% CI, 4.5-8.9) in non-SVR patients. Factors independently associated with liver decompensation were non-SVR (hazard ratio [HR], 8.1; 95% CI, 1.08-61.5; P = .042) and MELD score ≥9 at baseline (HR, 2.9; 95% CI, 1.2-7.2; P = .016). Two (4.6%) patients with SVR died due to any cause compared with 22 (17.9%) individuals without SVR (P = .02). MELD score ≥9 (HR, 3.1; 95% CI, 1.3-7.7; P = .011) and non-SVR (HR, 8.0; 95% CI, 1.07-61; P = .043) were independently associated with overall mortality. CONCLUSIONS The achievement of SVR following peg-IFN plus RBV markedly reduces the incidence of liver-related decompensation and the overall mortality in HIV/HCV-coinfected patients with compensated cirrhosis.
