Abstract
Chronic infection with the hepatitis C virus (HCV) remains a major health problem affecting approximately 58 million people worldwide. In the era of interferon (IFN)-based regimens, patients particularly infected with genotypes 1 and 4 achieved a low response rate. The implementation of direct-acting antivirals changed the landscape of HCV treatment. The increase in effectiveness provided us with the hope of eliminating HCV as a significant public threat by 2030. In the following years, there was an observed improvement in the treatment of HCV with genotype-specific regimens and highly effective pangenotypic options that are the most recent stage of the revolution. The optimization of therapy was accompanied by changes in the patient profile from the beginning of the IFN-free era over time. Patients treated with antiviral therapies were younger in successive periods, less burdened with comorbidities and comedications, more frequently treatment-naïve and had less advanced liver disease. Before the IFN-free era, specific subpopulations such as patients with HCV/HIV coinfection, those with a history of previous treatment, patients with renal impairment or with cirrhosis had lower chances for a virologic response. Currently, these populations should no longer be considered difficult to treat. Despite the high effectiveness of HCV therapy, there is a small percentage of patients with treatment failure. However, they can be effectively retreated with pangenotypic rescue regimens.

Pangenotypic and Genotype-Specific Antivirals in the Treatment of HCV Genotype 4 Infected Patients with HCV Monoinfection and HIV/HCV Coinfection. J Clin Med 2022; 11:jcm11020389.

Abstract
The introduction of the direct-acting antivirals (DAA) has substantially improved the effectiveness of the therapy in patients with chronic hepatitis C. We aimed to compare the efficacy of pangenotypic and genotype-specific DAA in the cohort of genotype (GT) four patients with HCV monoinfection and HIV coinfection. A total of 662 GT4-infected patients treated in 2015–2020—of whom 168 (25.3%) were coinfected with HIV, selected from the retrospective EpiTer-2 database—were enrolled in the analysis. Among HIV-coinfected patients, 54% (90) were treated with genotype-specific regimens and 46% (78) with pangenotypic options, while among HCV-monoinfected patients, the rates were 72% and 28%, respectively. Significantly higher rate of males (67.9% vs. 57.7%, p = 0.01), a lower rate of liver cirrhosis (10.2% vs. 18.1%, p = 0.02), and higher of treatment-naïve patients (87.5% vs. 76.7%, p = 0.003) were documented in the HIV coinfected population. The overall sustained virologic response after exclusion of non-virologic failures was achieved in 98% with no significant difference between HIV-positive and HIV-negative patients, 96.2% vs. 98.5%, respectively. While the genotype-specific regimens resulted in a similar cure rate regardless of the HIV status, the pangenotypic options were more efficacious in patients with HCV monoinfection (99.3% vs. 94.4%, p = 0.05). Hereby, we demonstrated the high effectiveness and good safety profile of the DAA therapy in the population of HCV GT4 infected patients with HIV coinfection supporting the current recommendations to treat HCV/HIV coinfected patients with the same options as those with HCV monoinfection.

Immunological and Clinical Impact of DAA-Mediated HCV Eradication in a Cohort of HIV/HCV Coinfected Patients: Monocentric Italian Experience. Diagnostics (Basel) 2021; 11:2336.

Abstract
HCV treatment became available for all infected patients regardless of their comorbidities, especially for HIV coinfected subjects, leading to an improvement in both clinical and immunological conditions. We retrospectively analyzed a cohort of HIV/HCV coinfected patients treated with DAA therapies; data regarding epidemiological, viral-immunological, and hepatic parameters before and after DAA administration have been collected. Drug-drug interactions between DAA and both antiretroviral therapy and non-ART-drugs were also evaluated; the study showed the efficacy of DAA schedules in HCV eradication also for HIV/HCV patients with multiple comorbidities and assuming many different drugs. Principal issues are still represented by drug interactions, pill burden, and patients' compliance. These concerns have to be taken into account, especially in HIV patients for whom the immunological state and ART interactions should always be considered.

Abstract
BACKGROUND The current recommendation for treating hepatitis C virus (HCV) in HIV patients includes the combination of sofosbuvir (SOF) and daclatasvir (DCV). DCV should be used at different doses to compensate for interactions with antiretroviral therapy (ART). Up to three pills a day might be required which will significantly add to the pill burden of these patients. In this study, we have used a single-tablet approach to treating HCV-HIV coinfection. METHODS Patients coinfected with HIV and HCV were prospectively enrolled from 10 centers throughout the country. Patients received a single once-daily fixed dose combination (FDC) pill containing 400 mg SOF and 30, 60 or 90 mg DCV depending on the type of ART they were receiving for 12 or 24 weeks. (ClinicalTrials.gov ID: NCT03369327). RESULTS Two hundred thirty-three patients were enrolled from 10 centers. Twenty-three patients were lost to follow-up and two patients died from causes unrelated to treatment. Two hundred eight patients completed the treatment course of which 201 achieved SVR (96.6%). CONCLUSION Single-tablet combination of DCV and SOF is an effective and safe treatment for patients coinfected with HIV and HCV. The combination works well in patients on ART in which dose adjustment is required. Patients with cirrhosis, previous treatment failure and various genotypes respond identically. The expenses of genotyping can be saved.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2020; 86:102974. [PMID: 33068831 DOI: 10.1016/j.drugpo.2020.102974] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2020] [Revised: 09/11/2020] [Accepted: 09/14/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND Globally, research on the co-infection of the human immunodeficiency virus (HIV) and hepatitis C virus (HCV) among people who inject drugs is growing. However, studies in resource-poor countries remain limited. Therefore, we conducted this study to explore factors associated with HIV/HCV co-infection among people who inject drugs in Cambodia. METHODS This national survey was conducted in 2017 in the capital city and 11 provinces. We used a 'peer-based social network recruitment' method to recruit 286 participants for face-to-face interviews and HIV and HCV testing. A modified Cox proportional hazard model was used to identify risk factors associated with HIV/HCV co-infection. RESULTS The prevalence of HIV and HCV was 15.4% and 30.4%, respectively. Of the total, 9.4% of the participants were HIV/HCV co-infected, and 61.4% of the HIV-infected participants were co-infected with HCV. About half (56.8%) of the participants tested HIV positive were aware of their HIV status; of whom, 83.3% were on antiretroviral therapy. Only 11.5% of the participants with HCV antibody positivity were aware of their HCV infection status; of whom, 50.0% were on HCV treatment. The adjusted prevalence ratio (APR) of HIV/HCV co-infection was significantly higher among women than among men and among participants who lived on the streets than among those living with their family or relatives. The APR of HIV/HCV co-infection was also significantly higher among participants who had received methadone maintenance therapy than those who had not received it. CONCLUSIONS The prevalence of HIV/HCV co-infection among people who inject drugs in Cambodia was considerably high. Intervention programs are required to increase access to harm-reduction interventions among most marginalized people who inject drugs to prevent HIV and HCV infection. HCV screening services should be expanded in this key population, given its small population size and the availability of directly-acting antiviral agents in the country.

Abstract
BACKGROUND Because of shared modes of transmission, patients with hepatitis C virus (HCV) infection are often co-infected with other types of hepatitis viruses and/or HIV. We studied HCV viral load and its genotype patterns among HCV mono- and HCV/HIV co-infected Illicit Drug Users in Fars province-Iran. METHODS Totally, 580 HCV seropositive IDUs referred to Prof. Alborzi Clinical Microbiology Research Center, Shiraz, Iran, without receiving any anti-HCV treatment, were enrolled. After their HCV infections were reconfirmed by one step rapid diagnostic test, HCV RNA level and HCV genotypes were determined by Taq-man real-time PCR assays. Their HIV serostatus was determined and seropositive patients were excluded from the group. In addition, 104 HIV/HCV co-infected IDUs referred from Shiraz Behavioral Diseases Consultation Center (SBDC) were assessed for HCV RNA level and HCV genotype patterns, as well. RESULTS The overall estimated HIV prevalence was 6.7% (39/580) among HCV seropositive IDUs. Genotype 1, the most prevalent genotype in both groups, was detected in 69% and 49% of co- and mono-infected IDUs, respectively. Median HCV viral load was significantly higher in HIV/HCV co-infected patients, compared with that among HCV mono-infected counterparts. CONCLUSIONS Given the higher baseline HCV viral load and GT1 attributed to poorer treatments response, HCV treatment must be more considered among HCV/HIV co-infected IDUs, compared to those mono-infected with HCV.

Abstract
Recombination in RNA virus is a rare event in the survival and evolution to evade host immune system. This is increasing within high risk group population (HRG) due to super infection that occurs by continuous sharing of common drug equipment by HCV infected or HIV-HCV co-infected recurrent drug users. Recombination causes impediment to vaccine development and therapeutic intervention as standard HCV treatment is still genotype specific. Blood samples of 194 people who inject drugs (PWID) were collected from an Opioid Substitution Therapy Centre in Kolkata, India. HCV sero-reactivity was checked by ELISA. Detection of HCV RNA by nested RT-PCR and genotyping by DNA sequencing were done. Phylogenetic analysis, Simplot, Bootscan plot, Recombination Detection Program were used for recombinant strain identification. Out of 80 HCV sero-reactive samples, 77 were RNA positive (96.25%). Out of 74 HIV mono-infected individuals, 12 HCV sero-nonreactive samples were HCV RNA positive. Out of total 89 RNA positive samples, 64 paired partial core and NS5B region (71.9%) were sequenced by Sanger's method. Two major genotypes (1 and 3), four subtypes and an inter-genotype recombinant strain (3a/1a) with a novel breakpoint in the NS4B coding region were found.

Abstract
BACKGROUND Human immunodeficiency virus (HIV)/hepatitis C virus (HCV) coinfection has become a serious public health problem. The influence of HIV/HCV coinfection on plasma HCV RNA loads and clinical criteria which are usually regarded as a predictor of the progress of liver disease have not been reliably evaluated. OBJECTIVES This study investigated the impact of HIV infection on HCV RNA load and clinical indexes in Yazd and Tehran. MATERIALS AND METHODS HCV/HIV-coinfected patients and HCV-monoinfected controls were examined and compared for plasma HCV RNA and related risk factors such as HCV genotypes, liver enzymes, and transmission routes. RESULTS A total of 54 HCV/HIV-coinfected patients and 88 HCV-monoinfected controls were studied. The HCV RNA load mean was significantly higher in HCV/HIV-coinfected patients than in HCV-monoinfected patients (p < 0.001). HCV RNA load mean in patients infected with HCV without anti-HCV therapy was lower than HIV/HCV patients with and without highly active antiretroviral therapy that this difference was significant (p < 0.001). The HCV RNA levels were significantly higher in HIV/HCV genotype 3a coinfected patients than in genotype 3a monoinfected patients (p < 0.001). HIV RNA levels were lower in genotype 1a infected patients than in genotype 3a infected patients, but this difference was not significant statistically. The ALT mean levels were significantly higher in genotype 3a HIV/HCV-coinfected patients than in genotype 3a HCV-monoinfected patients (p < 0.001). CONCLUSIONS HIV/HCV coinfection leads to a significant increase in plasma HCV RNA. Further evaluations of the effects of ART and HIV infection on the course of HCV infection and the response to treatment against HCV infection in other and different genotypes are also needed. Moreover, HIV-infected patients should be screened regularly for HCV coinfection, particularly if they are in high-risk groups such as IDUs and recipients of blood transfusions.

Abstract
BACKGROUND Highly effective hepatitis C virus (HCV) direct-acting antiviral therapies that do not require modification of human immunodeficiency virus (HIV) antiretroviral regimens are needed. We evaluated the efficacy and safety of daclatasvir + sofosbuvir (DCV + SOF) for 12 weeks by antiretroviral (ARV) regimen in HIV-HCV-coinfected patients. METHODS In the randomized, open-label ALLY-2 study, HIV-HCV-coinfected patients received 8 or 12 weeks of once-daily DCV 60 mg (dose-adjusted as-necessary for concomitant ARVs) + SOF 400 mg. Results were stratified by ARV class for the 151 patients who received 12 weeks of DCV + SOF. RESULTS Fifty-one patients were HCV treatment experienced, 100 were treatment naive, 89% male and 33% black. HCV genotypes were: genotype 1a (GT1a; 69%), GT1b (15%), GT2 (8%), GT3 (6%), and GT4 (2%). Sustained virologic response 12 weeks post-treatment (SVR12) was 97% and was similar across ARV regimens (P = .774): protease inhibitor-based, 97% (95% confidence interval [CI], 90%-99.7%); nonnucleoside reverse transcriptase inhibitor-based, 100% (95% CI, 91%-100%); and integrase inhibitor based, 95% (95% CI, 83%-99.4%). SVR12 among patients receiving either tenofovir disoproxil fumarate or abacavir as part of their antiretroviral therapy regimen was 98% (95% CI, 93%-99.5%) and 100% (95% CI, 85%-100%), respectively. Age, gender, race, cirrhosis, HCV treatment history, GT , and baseline HCV RNA did not affect SVR12. No discontinuations were attributed to treatment-related adverse events. CONCLUSIONS DCV + SOF x12 weeks is a highly efficacious, all-oral, pan-GT HCV treatment for HIV-HCV coinfected patients across a broad range of ARV regimens. CLINICAL TRIALS REGISTRATION NCT02032888.

Reduced healthcare utilization following successful hepatitis C virus treatment in HIV-co-infected patients with mild liver disease. J Viral Hepat 2016; 23:123-9. [PMID: 26511293 PMCID: PMC4924594 DOI: 10.1111/jvh.12484] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2015] [Accepted: 08/31/2015] [Indexed: 12/27/2022]
Abstract
New direct-acting antivirals (DAA) for hepatitis C virus (HCV) infection have achieved high cure rates in many patient groups previously considered difficult-to-treat, including those HIV/HCV co-infected. The high price of these medications is likely to limit access to treatment, at least in the short term. Early treatment priority is likely to be given to those with advanced disease, but a more detailed understanding of the potential benefits in treating those with mild disease is needed. We hypothesized that successful HCV treatment within a co-infected population with mild liver disease would lead to a reduction in the use and costs of healthcare services in the 5 years following treatment completion. We performed a retrospective cohort study of HIV/HCV-co-infected patients without evidence of fibrosis/cirrhosis who received a course of HCV therapy between 2004 and 2013. Detailed analysis of healthcare utilization up to 5 years following treatment for each patient using clinical and electronic records was used to estimate healthcare costs. Sixty-three patients were investigated, of whom 48 of 63 (76.2%) achieved sustained virological response 12 weeks following completion of therapy (SVR12). Individuals achieving SVR12 incurred lower health utilization costs (£5,000 per-patient) compared to (£10 775 per-patient) non-SVR patients in the 5 years after treatment. Healthcare utilization rates and costs in the immediate 5 years following treatment were significantly higher in co-infected patients with mild disease that failed to achieve SVR12. These data suggest additional value to achieving cure beyond the prevention of complications of disease.

Abstract
HIV infection may enhance immune-activation, while little is known regarding the role of HCV infection. This study investigates the impact of HCV in HIV coinfected patients with undetectable viraemia under HAART on the levels of peripheral T cell's immune-activation. We determined T lymphocytes subsets to characterize immune-activation defined as CD38 and/or HLA-DR expression in chronic monoinfected HCV, HIV, and HIV/HCV coinfected subjects. One hundred and fifty six patients were divided into three groups: (i) 77 HIV+ patients; (ii) 50 HCV+ patients; and (iii) 29 coinfected HIV/HCV patients. The level of CD4(+) was significantly higher in HCV+ than in HIV+ or in coinfected HIV/HCV subjects. The frequencies of CD4(+) CD38(+) /HLA-DR(-) , CD4(+) CD38(-) /HLA-DR(+) and CD4(+) CD38(+) /HLA-DR(+) in HIV+ patients were comparable to those measured in coinfected patients, but statistically higher than those observed in HCV+ subjects. The percentage of CD8(+) was comparable in HIV-1+ patients and coinfected HIV/HCV but the results obtained in both groups were significantly higher compared to the results obtained in HCV patients. The level of CD8(+) CD38(+) /HLA-DR(-) showed values lower in HIV+ patients than in that monoinfected HCV and coinfected HIV/HCV patients. The frequencies of CD8(+) CD38(-) /HLA-DR(+) were higher in HIV+ patients compared to HCV+ and coinfected HIV/HCV patients. HIV/HCV coinfected group showed highest levels of CD8(+) CD38(+) /HLA-DR(+) . HIV plays a pivotal role to determine the immune activation in the host. The role of HCV needs of further investigations but our data show that HCV mainly influences the immune-activation of the pool of CD8, but also probably plays a supporting additive effect on CD4 immune-activation.

Abstract
BACKGROUND Vietnam bears a high burden of hepatitis C virus (HCV) and HIV infection among persons who inject drugs (PWID). The high prevalence of HCV and HIV occurs in a context of stigma and limited preventive interventions for PWID. OBJECTIVES This study aims to estimate the prevalence of HCV, HIV, and HIV/HCV coinfection among PWID and to explore their associations with lifetime injection behaviors. METHODS A total of 1434 PWID were recruited from the Thai Nguyen Province of Vietnam between 2005 and 2007. Participants responded to a structured questionnaire and provided blood samples at baseline. A cross-sectional analysis of data collected at baseline was carried out. Factors associated with HCV monoinfection and HIV/HCV coinfection were evaluated by multinomial logistic regression. RESULTS The prevalences of HIV and HCV were 35.1 and 88.8%, respectively, and the prevalences of HIV/HCV coinfection and HCV monoinfection were 34.8 and 53.9%, respectively. After adjusting for confounders in multivariate analysis, ever reusing a syringe and needle was found to be significantly associated with HIV monoinfection [adjusted odds ratio (AOR), 3.13; 95% confidence interval (CI), 1.99-4.94] and HIV/HCV coinfection (AOR, 3.34; 95% CI, 2.02-5.51). Ever sharing diazepam or novocaine was also found to be significantly associated with HIV monoinfection (AOR, 2.14; 95% CI, 1.38-3.32) and HIV/HCV coinfection (AOR, 2.47; 95% CI, 1.57-3.90). CONCLUSION Our findings demonstrate a high burden of HIV and HCV infection among PWID in Vietnam. Lifetime injection behaviors, including sharing of diazepam or novocaine, may account for the high prevalence of HIV and HCV. Improving prevention and ensuring access to care remain critically important for this vulnerable population.

Abstract
INTRODUCTION There are several clinical trials and prospective studies which support the use of direct-acting antiviral agents (DAAs) in hepatitis C virus (HCV)-coinfected patients. In this review, the safety of DAAs in HCV patients coinfected with hepatitis B virus (HBV) or HIV has been evaluated. AREAS COVERED All available prospective studies, clinical trials and congress abstracts in the English language that assessed the safety and efficacy of DAAs in HCV coinfections have been considered. EXPERT OPINION The newer DAAs in the treatment of HCV/HIV-coinfected patients resolved major limitations of the first-generation protease inhibitors including complex dosing, poor tolerability and interactions with antiretroviral drugs. There are not yet enough data regarding the safety and efficacy of DAAs in some coinfected patients with comorbidities, nor for pregnant, lactating or pediatric patients. Evaluating the safety and efficacy of these agents in these subgroups with HCV coinfection is recommended for future studies. The role of new direct-acting antiviral-based therapy for the treatment of patients with HCV/HBV coinfection remains to be evaluated.

Abstract
There are an estimated 40 million HIV infected individuals worldwide, with chronic liver disease being the 2nd leading cause of mortality in this population. Elevated liver functions are commonly noted in HIV patients and the etiologies are varied. Viral hepatitis B and C, fatty liver and drug induced liver injury are more common. Treatment options for viral hepatitis C are rapidly evolving and are promising, but treatments are limited for the other conditions and is primarily supportive. Opportunistic infections of the liver are now uncommon. Irrespective of etiology, management requires referral to specialized centers and with due diligence mortality can be reduced.

Abstract
Nevirapine (NVP) is an effective nonnucleoside reverse transcriptase inhibitor (NNRTI) of particular interest as it is often used in resource limited countries. However, one of the main concerns with the use of NVP is hepatotoxicity and elevation of liver enzymes as a consequence of highly active antiretroviral therapy (HAART) containing NVP is more often reported in HIV patients coinfected with hepatitis C virus than in HIV-monoinfected patients. To discover possible markers of NVP induced hepatotoxicity, serum and urine samples from twenty-five HIV or HIV/HCV patients, all of whom had received NVP continuously for at least four months, and healthy controls were subjected to in-solution or in-gel proteomic analysis. A total of 83 differentially regulated proteins consisted of 34 proteins identified in serum by in-solution analysis, 2 proteins identified from serum in a 2D gel electrophoresis analysis, and 47 proteins identified in urine in an in-solution analysis. Three proteins, namely, haptoglobin, Rho-related BTB domain containing protein 3, and death-associated protein kinase 3, were selected for further validation by Western blot analysis and results showed that haptoglobin has potential for further development as an additional marker of NVP induced hepatotoxicity.

Abstract
Hepatitis C virus (HCV) infection is a major cause of morbidity and mortality in the HIV co-infected population. Interferon-alpha (IFN-α) remains a major component of anti-HCV therapy despite its deleterious effects on the immune system. Furthermore, IFN-α was recently shown to diminish the size of the latent HIV reservoir. The objectives of this study were to monitor the impact of IFN-α on T cell phenotype and proliferation of HIV and HCV-specific T cells during IFN therapy, and to identify immune markers that can predict the response to IFN in HICV/HIV co-infected patients. We performed longitudinal analyses of T cell numbers, phenotype and function in co-infected patients undergoing IFN-α therapy with different outcomes including IFN-α non-responders (NR) (n = 9) and patients who achieved sustained virologic response (SVR) (n = 19). We examined the expression of activation (CD38, HLA-DR), functional (CD127) and exhaustion markers (PD1, Tim-3, CD160 and CD244) on total CD4 and CD8 T cells before, during and after therapy. In addition, we examined the HIV- and HCV-specific proliferative responses against HIV-p24 and HCV-NS3 proteins. Frequencies of CD127+ CD4 T cells were higher in SVR than in NR patients at baseline. An increase in CD127 expression on CD8 T cells was observed after IFN-α therapy in all patients. In addition, CD8 T cells from NR patients expressed a higher exhaustion status at baseline. Finally, SVR patients exhibited higher proliferative response against both HIV and HCV antigens at baseline. Altogether, SVR correlated with higher expression of CD127, lower T cell exhaustion status and better HIV and HCV proliferative responses at baseline. Such factors might be used as non-invasive methods to predict the success of IFN–based therapies in co-infected individuals.

Abstract
BACKGROUND Many patients with chronic hepatitis C virus (HCV) being treated with pegylated interferon (peg-IFN) plus ribavirin (RBV) do not respond to therapy and do not clear the virus. Standard of care during the era of dual therapy was to discontinue the patient's therapy based on insufficient decreases in viral load after 12 and/or 24 weeks on therapy. OBJECTIVES We identified patient characteristics that were significant predictors of discontinuation as a result of lack of efficacy (LOE) in a national database of US veterans with genotypes 1 and 4. METHODS We identified US veterans who received care at Veterans Affairs medical centers in 2004-2009 and who had lab-confirmed HCV diagnoses and initiated therapy with peg-IFN plus RBV. Patients who discontinued therapy early were classified as either LOE or non-LOE discontinuers based on pharmacy refill patterns and laboratory response data. Predictors of LOE discontinuation were identified using univariate and multivariable Cox proportional hazards modeling. RESULTS Of 321 238 HCV patients with an ICD-9 diagnosis code, 31 215 (9.7%) initiated dual therapy with peg-IFN plus RBV, and 10 333 (3.2%) met all inclusion criteria and were included in the analysis. Overall, 13.6% of the cohort was classified as LOE. Significant predictors of LOE discontinuation included treatment for drug abuse (hazard ratio [HR] = 2.18), age >65 years (HR = 1.75), antiretroviral therapy for HIV (HR = 1.48), black race (HR = 1.47), platelet count >100/mm3 (HR = 1.46), and drug therapy for insomnia (HR = 1.40). CONCLUSIONS We identified risk factors for discontinuation caused by LOE. Future work should focus on determining whether these characteristics are also predictive of triple-therapy LOE discontinuations.

Abstract
Background In HIV infected patients, the impact of ribavirin (RBV) pharmacology on sustained virologic response (SVR) to hepatitis C virus (HCV) treatment has not been fully investigated. The objective of this study was to compare the early RBV plasma exposure between a population of HIV-HCV coinfected patients and an HCV monoinfected group. Methods Early RBV plasma exposure (expressed as Area Under the Curve (AUC) from 0 to 4 h) after a 600 mg first dose of RBV was measured in a population of HIV-HCV coinfected patients in comparison with an HCV monoinfected group. Peripheral blood samples were collected before the 600 mg RBV first dose (T0) to ensure no detectable baseline plasma RBV, and then 30 mn, 1, 2 and 4 hours after RBV intake (T0.5, T1, T2 and T4). Results Eighty-six patients with chronic hepatitis C entered the study among whom 23 (27%) were HIV-HCV coinfected. Coinfected patients had a significantly lower RBV-AUC 0-4h (median: 1469 μg*h/L [range 936–3677]) compared with monoinfected patients (2030 μg*h/L [851–7700]; p = 0.018). This RBV under exposure in coinfected patients persisted after normalization of AUC to RBV dose per kilogram of body weight (182 μg*h/L [110–425] versus 271 μg*h/L [82–1091], p = 0.001). Conclusions These results suggest that lower early bioavailability of RBV could be one of the reasons for lower SVR in HIV-HCV coinfected patients treated with pegylated interferon/RBV combination therapy. RBV plasma underexposure seems to be associated with the immunological status of the patients with lower AUC0-4h values observed in the more immunosuppressed coinfected patients.

Abstract
HIV-1/HCV co-infection is a significant health problem. Highly active antiretroviral treatment (HAART) against HIV-1 has proved to be fairly successful. On the other hand, direct acting antiviral drugs against HCV have improved cure rates but high cost and development of drug resistance are important concerns. Therefore PEGylated interferon (PEG-IFN) and ribavirin (RBV) still remain essential components of HCV treatment, and identification of host factors that predict IFN/RBV treatment response is necessary for effective clinical management of HCV infection. Impaired dendritic cell (DC) and T cell responses are associated with HCV persistence. It has been shown that IFN/RBV treatment enhances HCV-specific T cell functions and it is likely that functional restoration of DCs is the underlying cause. To test this hypothesis, we utilized an antibody cocktail (consisting of DC maturation, adhesion and other surface markers) to perform comprehensive phenotypic characterization of myeloid DCs (mDCs) and plasmacytoid DCs (pDCs) in a cohort of HIV-1/HCV co-infected individuals undergoing IFN/RBV treatment. Our results show that pre-treatment frequencies of mDCs are lower in non-responders (NRs) compared to responders (SVRs) and healthy controls. Although, the treatment was able to restore the frequency of mDCs in NRs, it downregulated the frequency of CCR7+, CD54+ and CD62L+ mDCs. Pre-treatment frequencies of pDCs were lower in NRs and decreased further upon treatment. Compared to SVRs, NRs exhibited higher ratio of PD-L1+/CD86+ pDCs prior to treatment; and this ratio remained high even after treatment. These findings demonstrate that enumeration and phenotypic assessment of DCs before/during therapy can help predict the treatment outcome. We also show that before treatment, PBMCs from SVRs secrete higher amounts of IFN-γ compared to controls and NRs. Upon genotyping IFNL3 polymorphisms rs12979860, rs4803217 and ss469415590, we found rs12979860 to be a better predictor of treatment outcome. Collectively, our study led to identification of important correlates of IFN/RBV treatment response in HIV-1/HCV co-infected individuals.

Abstract
Little is known about the epidemiological characteristics of HIV/hepatitis C virus (HCV) co-infection in cities in China with low HIV prevalence. This study evaluated the level of exposure to different risk factors associated with HCV transmission and characterized the distribution of HCV genotypes in 356 HIV-1-positive patients in Wuhan, central China. HIV transmission routes were distributed as follows: heterosexual contact, male-to-male sexual contact, intravenous drug use, blood transfusion, and unknown route. HCV antibodies were detected by a third-generation enzyme-linked immunosorbent assay. HCV-positive plasmas were subjected to RNA extraction, RT-PCR amplification, and sequencing. Phylogenetic analysis characterized HCV subtypes and the evolutionary origin of circulating HCV strains. Ninety-two of 356 (25.8%) patients infected with HIV were anti-HCV-positive. Among co-infected patients, the predominant risk for HCV transmission was intravenous drug use (87.3%). Six HCV subtypes (1a, 1b, 2a, 3a, 3b, and 6a) were detected. HCV genotype 6a was most prevalent, occurring in 39.3% of all patients, followed by genotypes 1b (24.7%), 3b (18.0%), and 3a (9.8%). The least frequent genotypes were 1a (4.9%) and 2a (3.3%). Intravenous drug use was strongly associated with genotype 6a, and infection by blood or blood product transfusion was strongly associated with genotype 1b. Genotype 2a was detected only among those infected by male-to-male sexual contact. The distribution of HCV subtypes suggests that the city plays a crucial role as a hub of HCV transmission in China. Exposure to multiple risk factors associated with HCV transmission was common among patients co-infected with HIV and HCV.

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
Introduction Despite recommendations for generation-based HCV and once lifetime HIV screening, thousands of individuals in the U.S. still remain untested and undiagnosed. This cross-sectional study examines the correlates of HCV and HIV monoinfection and HIV/HCV coinfection in an urban Northeast setting. Methods Utilizing an electronic database from a mobile medical clinic in New Haven, CT from January 2003 to July 2011, 8,311 individuals underwent structured health assessment and screening for HIV and HCV. Results HIV [N = 601 (8.0%)] and HCV [N = 753 (10.1%)] infection were identified, and 197 (26.1%) of the 753 with HCV were coinfected with HIV. Both monoinfection and coinfection status were independently correlated with crack cocaine use and increasing age. HIV/HCV coinfection was correlated with men having sex with men (MSM) (AOR = 38.53, p<0.0080), shooting gallery use (AOR = 3.06, p<0.0070), and not completing high school (AOR = 2.51, p<0.0370). HCV monoinfection correlated with health insurance (AOR = 2.16, p<0.0020), domestic violence (AOR = 1.99, p<0.0070), and being Hispanic (AOR = 2.63, p<0.0001), while HIV monoinfection correlated with having had syphilis (AOR = 2.66, p<0.0001) and being Black (AOR = 1.73, p = 0.0010). Conclusions Though HIV and HCV share common transmission risk behaviors, independent correlates with viral infection status in an urban Northeast setting are distinct and have important implications for surveillance, healthcare delivery, disease prevention, and clinical care.

Abstract
Co-infection with either HIV or HBV in chronic hepatitis C patients is common, since all these viruses share transmission routes and geographical distribution. Interaction between these viruses generally amplifies liver damage, increasing the risk of developing end-stage liver disease and hepatocellular carcinoma. HIV-HCV co-infection is associated with poorer response to antiviral therapy. New antivirals against HCV are eagerly awaited for this population. HBV-HCV dual infections are less common. The principles guiding indication of therapy in monoinfected patients should be followed considering which virus replicates in persons with serological markers of dual HBV-HCV infection. Although there is growing evidence supporting the use of direct acting antivirals (DAA) in dually infected patients with active HCV replication, prospective trials should be conducted to demonstrate their benefit, assessing carefully the rate and clinical consequences of HBV rebounds.

Abstract
Innate immunity provides frontline antiviral protection and bridges adaptive immunity against virus infections. However, viruses can evade innate immune surveillance potentially causing chronic infections that may lead to pandemic diseases. Porcine reproductive and respiratory syndrome virus (PRRSV) is an example of an animal virus that has developed diverse mechanisms to evade porcine antiviral immune responses. Two decades after its discovery, PRRSV is still one of the most globally devastating viruses threatening the swine industry. In this review, we discuss the molecular and cellular composition of the mammalian innate antiviral immune system with emphasis on the porcine system. In particular, we focus on the interaction between PRRSV and porcine innate immunity at cellular and molecular levels. Strategies for targeting innate immune components and other host metabolic factors to induce ideal anti-PRRSV protection are also discussed.

Abstract
OBJECTIVES The C allele of the single nucleotide polymorphism rs12979860, located near the interleukin-28B (IL-28B) gene, has a strong impact on hepatitis C virus (HCV) treatment response, as well as on spontaneous viral clearance. In patients with chronic hepatitis C (CHC), genotype CC carriers harbour HCV genotype 3 more commonly than those with non-CC genotypes. The aim of this study was to compare the HCV genotype distributions, according to IL-28B genotype, in HIV-infected patients with CHC and those with acute hepatitis C (AHC). METHODS The rs12979860 genotype was determined by polymerase chain reaction (PCR) in two subpopulations of HIV-infected patients. The first consisted of 80 German patients with AHC. The second consisted of 476 patients with CHC, belonging to one German and two Spanish cohorts. RESULTS In the AHC group, 31 (81.6%) rs12979860 CC carriers were infected with HCV genotype 1 or 4 vs. 32 (76.2%) among non-CC carriers (P=0.948). In patients with CHC, among those with the CC genotype, 119 (54.6%) were infected with HCV genotype 1 or 4 and 99 (45.4%) with genotype 2 or 3, whereas in the subset with non-CC genotypes, 200 (77.5%) harboured HCV genotype 1 or 4 and 58 (22.5%) genotype 2 or 3 (P<0.001). CONCLUSIONS Among HIV-infected patients with CHC, those bearing the IL-28B genotype CC were more commonly infected with genotype 3 than subjects with non-CC genotypes, whereas in HIV-infected subjects with AHC this finding was not obtained. These results strongly suggest that the protective effect of the CC genotype against evolution to CHC is mainly exerted in patients infected with HCV genotype 1 or 4.

Abstract
BACKGROUND Human leukocyte antigen (HLA) class I and II genotype is associated with clearance of hepatitis C virus (HCV) infection, but little is known regarding its relation with HCV viral load or risk of liver disease in patients with persistent HCV infection. METHODS High-resolution HLA class I and II genotyping was conducted in a prospective cohort of 519 human immunodeficiency virus (HIV)-seropositive and 100 HIV-seronegative women with persistent HCV infection. The end points were baseline HCV viral load and 2 noninvasive indexes of liver disease, fibrosis-4 (FIB-4), and the aspartate aminotransferase to platelet ratio index (APRI), measured at baseline and prospectively. RESULTS DQB1*0301 was associated with low baseline HCV load (β = -.4; 95% confidence interval [CI], -.6 to -.3; P < .00001), as well as with low odds of FIB-4-defined (odds ratio [OR], .5; 95% CI, .2-.9; P = .02) and APRI-defined liver fibrosis (OR, .5; 95% CI, .3-1.0; P = .06) at baseline and/or during follow-up. Most additional associations with HCV viral load also involved HLA class II alleles. Additional associations with FIB-4 and APRI primarily involved class I alleles, for example, the relation of B*1503 with APRI-defined fibrosis had an OR of 2.0 (95% CI, 1.0-3.7; P = .04). CONCLUSIONS HLA genotype may influence HCV viral load and risk of liver disease, including DQB1*0301, which was associated with HCV clearance in prior studies.

Abstract
Abstract Our objective was to evaluate the liver toxicity of antiretroviral regimens including fosamprenavir plus ritonavir (FPV/r) 1400/100 mg once daily (QD) in HIV/hepatitis C virus (HCV)-coinfected patients. This was a prospective cohort study that included 117 HIV/HCV-coinfected patients who started FPV/r 1400/100 mg QD-based antiretroviral therapy (ART) and who neither had received a previous antiretroviral regimen containing FPV nor had a past history of virologic failure while receiving protease inhibitors (PI). The primary end point of the study was the occurrence of grade 3-4 liver enzymes elevations (LEE) within 1 year after starting FPV/r QD. Factors potentially associated with grade 3-4 LEE, including baseline liver fibrosis, were analyzed. Eleven (9%) patients had a grade 3-4 LEE during the follow-up, resulting in an incidence of severe liver toxicity of 9% (95% confidence interval 4.1-14.6%). None of these cases led to FPV/r discontinuation. Baseline liver fibrosis could be assessed in 97 (83%) patients. Six of 71 patients (8%) with significant fibrosis had a grade 3-4 LEE versus 2 of 26 (8%) without significant fibrosis (p=1.0). Twenty (21%) patients had cirrhosis at baseline. There were no cases of LEE among cirrhotics. In conclusion, the incidence of severe liver toxicity after 1 year of therapy with FPV/r QD-based ART in HIV/HCV-coinfected patients is similar to what has been reported with other boosted PIs. In addition, the presence of significant fibrosis or cirrhosis was not associated with the emergence of liver toxicity. Thus, ART regimens containing FPV/r QD may be considered safe in HIV/HCV-coinfected patients, including those with cirrhosis.

Abstract
Chronic hepatitis B virus (HBV) infection affects up to 14% of people living with HIV and AIDS (PLWHA) and is associated with a higher risk of non-AIDS death. While great advances have been made in the therapeutic management of co-infection with HIV and HBV, nothing is known about perceived health in people living with HIV and HBV. This study aimed at characterizing individuals with poor perceived overall health among 308 HIV-HBV co-infected individuals enrolled between May 2002 and May 2003 in a three-year French cohort. A binary score for perceived overall health (good vs. poor) was calculated from individuals' responses to the COOP-WONCA charts at cohort enrolment and at quarterly visits throughout the follow-up. Mixed models were used to explore factors associated with this score. At enrolment, 190 individuals (62%) reported poor overall health. In the multivariate analysis, low CD4 percentage, co-infection with hepatitis C or D viruses, HIV diagnosis before 1996 and HBeAg positivity were independently associated with poor perceived overall health. Poor perceived health concerns a considerable portion of individuals living with HIV and HBV. Individuals with wild-type HBV and multiple hepatitis infection require better clinical management. Further research is needed for hepatitis D virus infection, for which treatment options are currently very limited.

Abstract
UNLABELLED Acute hepatitis C continues to be a concern in men who have sex with men (MSM), and its optimal management has yet to be established. In this study, the clinical, biological, and therapeutic data of 53 human immunodeficiency virus (HIV)-infected MSM included in a multicenter prospective study on acute hepatitis C in 2006-2007 were retrospectively collected and analyzed. The mean hepatitis C virus (HCV) viral load at diagnosis was 5.8 ± 1.1 log(10) IU/mL (genotype 4, n = 28; genotype 1, n = 14, genotype 3, n = 7). The cumulative rates of spontaneous HCV clearance were 11.0% and 16.5% 3 and 6 months after diagnosis, respectively. Forty patients were treated, 38 of whom received pegylated interferon and ribavirin. The mean duration of HCV therapy was 39 ± 17 weeks (24 ± 4 weeks in 14 cases). On treatment, 18/36 (50.0%; 95% confidence interval 34.3-65.7) patients had undetectable HCV RNA at week 4 (RVR), and 32/39 (82.1%; 95 confidence interval 70.0-94.1) achieved sustained virological response (SVR). SVR did not correlate with pretreatment parameters, including HCV genotype, but correlated with RVR (predictive positive value of 94.4%) and with effective duration of HCV therapy (64.3% for 24 ± 4 weeks versus 92.0% for longer treatment; P = 0.03). CONCLUSION The low rate of spontaneous clearance and the high SVR rates argue for early HCV therapy following diagnosis of acute hepatitis C in HIV-infected MSM. Pegylated interferon and ribavirin seem to be the best option. The duration of treatment should be modulated according to RVR, with a 24-week course for patients presenting RVR and a 48-week course for those who do not, irrespectively of HCV genotype.

Abstract
The linkage between drug use, particularly injection drug use, and HIV/AIDS, hepatitis C (HCV), and tuberculosis (TB) has been recognized since the beginning of the HIV pandemic. These comorbid conditions affect drug users worldwide and act synergistically, with resultant adverse biologic, epidemiologic, and clinical consequences. Prevention, care, and treatment of TB and HCV can be successful, and both diseases can be cured. Special clinical challenges among drug users, however, can result in increased morbidity, mortality, and decreased therapeutic success. Among these are limited disease screening, inadequate and insensitive diagnostics, difficult treatment regimens with varying toxicities, and complicated pharmacokinetic and pharmacodynamic drug interactions. These may result in delayed diagnosis, deferred treatment initiation, and low completion rates, with the potential for generation and transmission of drug resistant organisms. Strategies to address these challenges include outreach programs to engage substance abusers in nonmedical settings, such as prisons and the streets, active screening programs for HIV, HCV, and TB, increased and broadened clinician expertise, knowledge and avoidance of drug interactions, attention to infection control, use of isoniazid preventive therapy, and creative strategies to insure medication adherence. All of these require structural changes directed at comprehensive prevention and treatment programs and increased collaboration and integration of needed services for substance abusers.

Abstract
Interferon-α (IFN-α)-based therapy is presently the standard treatment for hepatitis C virus (HCV)-infected patients. Despite good effectiveness, this cytokine is associated with major side effects, including significant lymphopenia, that limits its use for HIV/HCV-coinfected patients. Interleukin-7 (IL-7) has recently shown therapeutic potential and safety in several clinical trials designed to demonstrate T-cell restoration in immunodeficient patients. The purpose of this study was to evaluate, in simian immunodeficiency virus-infected rhesus macaques, the relevance of IL-7 therapy as a means to overcoming IFN-α-induced lymphopenia. We showed that low-dose IFN-α treatment induced strong lymphopenia in chronically infected monkeys. In contrast, high-dose IFN-α treatment stimulated IL-7 production, leading to increased circulating T-cell counts. Moreover, IL-7 therapy more than abrogated the lymphopenic effect of low-dose IFN-α. Indeed, the association of both cytokines resulted in increased circulating T-cell counts, in particular in the naive compartments, as a consequence of central and peripheral homeostatic functions of the IL-7. Finally, reduced PD-1 expression by memory CD8(+) T cells and transient T-cell repertoire diversification were observed under IL-7 therapy. Our data strongly suggest that IL-7 immunotherapy will be of substantial benefit in the treatment of HIV/HCV coinfection and should enhance the likelihood of HCV eradication in poorly responding patients.

Abstract
Adjuvant interferon (IFN)-alpha remains the standard adjuvant therapy for intermediate and high-risk melanoma after definitive surgical resection. Data addressing the role and safety of adjuvant immunotherapy in HIV-infected patients with melanoma are lacking. We report on an HIV(+) patient who received IFN-alpha as adjuvant treatment for high-risk melanoma. To our knowledge, this is the first reported case of such an approach.

Abstract
Patients co-infected with the human immunodeficiency virus (HIV) and the hepatitis C virus (HCV) are fraught with a rapid fibrosis progression rate and with complications of portal hypertension (PHT) We aimed to assess the influence of immune function [Centers of Disease Control and Prevention (CDC) stage] on development of PHT and disease progression in HIV-HCV co-infection. Data of 74 interferon-naïve HIV-HCV co-infected patients undergoing liver biopsy, measurement of portal pressure and of liver stiffness and routine laboratory tests (including CD4+ cell count, HIV and HCV viral load) were analysed. Time of initial exposure (risk behaviour) was used to assess fibrosis progression. Fibrosis progression, time to cirrhosis and portal pressure were correlated with HIV status (CDC stage). HIV-HCV patients had rapid progression of fibrosis [0.201 +/- 0.088 METAVIR fibrosis units/year (FU/y)] and accelerated time to cirrhosis (24 +/- 13 years), high HCV viral loads (4.83 x 10(6) IU/mL) and a mean HVPG at the upper limit of normal (5 mmHg). With moderate or severe immunodeficiency, fibrosis progression was even higher (CDC-2 = 0.177 FU/y; CDC-3 = 0.248 FU/y) compared with patients with higher CD4+ nadirs (CDC-1 = 0.120 FU/y; P = 0.0001). An indirect correlation between CD4+ cell count and rate of fibrosis progression (R = -0.6654; P < 0.001) could be demonstrated. Hepatic venous pressure gradient (HVPG) showed early elevation of portal pressure with median values of 4, 8 and 12 mmHg after 10, 15 and 20 years of HCV infection for CDC-3 patients. Patients treated with highly active anti-retroviral therapy (HAART) had similar rates of progression and portal pressure values than patients without HAART. Progression of HCV disease is accelerated in HIV-HCV co-infection, being more pronounced in patients with low CD4+ cell count. A history of a CD4+ cell nadir <200/microL is a risk factor for rapid development of cirrhosis and PHT. Thus, HCV treatment should be considered early in patients with HIV-HCV co-infection and largely preserved CD4+ cell counts.

Abstract
BACKGROUND Co-infection with HIV-1 and HCV is a significant global public health problem and a major consideration for anti-HIV-1 treatment. HCV infection among HIV-1 positive people who are eligible for the newly launched nationwide anti-HIV-1 treatment program in China has not been well characterized. METHODOLOGY A nationwide survey of HIV-1 positive injection drug uses (IDU), former paid blood donors (FBD), and sexually transmitted cases from multiple provinces including the four most affected provinces in China was conducted. HCV prevalence and genetic diversity were determined. We found that IDU and FBD have extremely high rates of HCV infection (97% and 93%, respectively). Surprisingly, people who acquired HIV-1 through sexual contact also had a higher rate of HCV infection (20%) than the general population. HIV-1 subtype and HCV genotypes were amazingly similar among FBD from multiple provinces stretching from Central to Northeast China. However, although patterns of overland trafficking of heroin and distinct HIV-1 subtypes could be detected among IDU, HCV genotypes of IDU were more diverse and exhibited significant regional differences. CONCLUSION Emerging HIV-1 and HCV co-infection and possible sexual transmission of HCV in China require urgent prevention measures and should be taken into consideration in the nationwide antiretroviral treatment program.

Abstract
BACKGROUND/AIMS HIV and hepatitis C virus (HCV) share common modes of transmission, resulting in about 33% incidence of coinfection among people infected with HIV. The survival benefit from highly effective antiretroviral therapy (HAART) for HIV infection is resulting in an increased incidence of hepatocellular carcinoma (HCC) in this population. There are no reports to date regarding the coadministration of HAART and sorafenib for hepatocellular carcinoma. METHODS We report the case of a 42-year-old male patient coinfected with HIV and HCV who developed advanced HCC not amenable to curative therapy. The patient was treated with sorafenib, an oral multikinase inhibitor shown to lead to a longer median survival time and time to progression in patients with advanced HCC. Antiretroviral therapy was continued during sorafenib therapy. RESULTS The patient achieved a partial tumor response after 3 months and continued to respond at subsequent assessments. His serum alpha-fetoprotein normalized from 2,172 IU/ml to 2 IU/ml. He had durable stable disease after 23 months of therapy. Antiretroviral therapy was efficacious (CD4(+) lymphocyte count, 377/microl; HIV viremia, <50 copies/ml). The simultaneous administration of these therapies was well tolerated. No grade 3 or 4 toxicities were observed. Exacerbation of pre-existing hypertension, grade 2 diarrhea, and grade 1 skin reaction were observed. CONCLUSIONS This is the first report in which sorafenib has been successfully used to treat HCC in a patient with HIV-HCV coinfection.

Abstract
BACKGROUND Autophagy has been reported to play a pivotal role on the replication of various RNA viruses. In this study, we investigated the role of autophagy on hepatitis C virus (HCV) RNA replication and demonstrated anti-HCV effects of an autophagic proteolysis inhibitor, chloroquine. METHODS Induction of autophagy was evaluated following the transfection of HCV replicon to Huh-7 cells. Next, we investigated the replication of HCV subgenomic replicon in response to treatment with lysosomal protease inhibitors or pharmacological autophagy inhibitor. The effect on HCV replication was analyzed after transfection with siRNA of ATG5, ATG7 and light-chain (LC)-3 to replicon cells. The antiviral effect of chloroquine and/or interferon-alpha (IFNalpha) was evaluated. RESULTS The transfection of HCV replicon increased the number of autophagosomes to about twofold over untransfected cells. Pharmacological inhibition of autophagic proteolysis significantly suppressed expression level of HCV replicon. Silencing of autophagy-related genes by siRNA transfection significantly blunted the replication of HCV replicon. Treatment of replicon cells with chloroquine suppressed the replication of the HCV replicon in a dose-dependent manner. Furthermore, combination treatment of chloroquine to IFNalpha enhanced the antiviral effect of IFNalpha and prevented re-propagation of HCV replicon. Protein kinase R was activated in cells treated with IFNalpha but not with chloroquine. Incubation with chloroquine decreased degradation of long-lived protein leucine. CONCLUSION The results of this study suggest that the replication of HCV replicon utilizes machinery involving cellular autophagic proteolysis. The therapy targeted to autophagic proteolysis by using chloroquine may provide a new therapeutic option against chronic hepatitis C.

Abstract
Hepatitis C infection is a major problem for approximately 250,000 HIV-infected persons in the United States. Although HIV infection is well-controlled in most of this population, they suffer liver-associated morbidity and mortality. Conversely, hepatitis C virus (HCV) treatment uptake remains quite low (15%-30%). Therefore, the purpose of this qualitative study was to explore HCV treatment experiences and decision making in adults with HIV infection. The study sample included 39 coinfected adults; 16 in the HCV-treated cohort (who were interviewed a maximum of 3 times) and 23 in the HCV-nontreatment cohort. Analysis of interviews identified 2 treatment barriers (fears and vicarious experiences) and 4 facilitating factors (experience with illness management, patient-provider relationships, gaining sober time, and facing treatment head-on). Analysis of these data also revealed a preliminary model to guide intervention development and theoretical perspectives. Ultimately, research is urgently needed to test interventions that improve HCV evaluation and treatment uptake among HIV-infected patients.

Abstract
Alcoholic liver disease (ALD) and hepatitis C virus (HCV) infection represent, either alone or in combination, more than two thirds of all patients with liver disease in the Western world. This review discusses the epidemiology and combined impact of ALD and HCV on the progression of liver disease. ALD and HCV affect the progression of liver disease to liver cirrhosis and hepatocellular carcinoma (HCC) in a synergistic manner. Thus, the risk for HCC increases five times with a daily alcohol consumption of 80 g; in the presence of HCV it is increased 20-fold, and a combination of both risk factors leads to a more than 100-fold risk for HCC development. Alcohol consumption also decreases the response to interferon treatment which is probably due to a lack of compliance than a direct effect on HCV replication. Several molecular mechanisms are discussed that could explain the synergistic interaction of alcohol and HCV on disease progression. They include modulation of the immune response and apoptosis, increased oxidative stress via induction of CYP2E1 and the hepatic accumulation of iron. Thus, both HCV and alcohol independently cause hepatic iron accumulation in > 50% of patients probably due to suppression of the liver-secreted systemic iron hormone hepcidin. A better understanding of hepcidin regulation could help in developing novel therapeutic approaches to treat the chronic disease in the future. For now, it can be generally concluded that HCV-infected patients should abstain from alcohol and alcoholics should be encouraged to participate in detoxification programs.

Abstract
Liver diseases associated with hepatitis C virus (HCV) infection have become the major cause of mortality in patients with human immunodeficiency virus (HIV) infection since the introduction of highly active anti-retroviral therapy. HCV-related liver disease is more severe in HIV-infected patients than in non-HIV-infected patients, but the standard therapies used to treat chronic hepatitis C in HCV/HIV coinfected patients are the same as those for patients infected with HCV alone. HIV protease inhibitors might have potential to down-regulate HCV load of HCV/HIV coinfected patients. In this study, we evaluated the effects of nelfinavir on intracellular HCV replication using the HCV replicon system. We constructed an HCV replicon expressing a neomycin-selectable chimeric firefly luciferase reporter protein. Cytotoxicity and apoptosis induced by nelfinavir were assessed and synergism between nelfinavir and interferon (IFN) was calculated using CalcuSyn analysis. Nelfinavir dose-dependently repressed HCV replication at low concentrations (IC(50), 9.88 micromol/L). Nelfinavir failed to induce cytotoxicity or apoptosis at concentrations that inhibited HCV replication. Clinical concentrations of nelfinavir (5 micromol/L) combined with IFN showed synergistic inhibition of HCV replication in our replicon model. Our results suggest that the direct effects of nelfinavir on the HCV subgenome and its synergism with IFN could improve clinical responses to IFN therapy in HCV/HIV coinfected patients.

Abstract
BACKGROUND How coinfection with hepatitis C virus (HCV) impacts on the trajectory of kidney function in human immunodeficiency virus (HIV)-infected patients is unclear. This study examined the effect of HCV infection on kidney function over time in women infected with HIV. STUDY DESIGN Retrospective observational cohort. SETTING & PARTICIPANTS Study sample included participants from the Women's Interagency HIV Study who were HIV infected and had undergone HCV antibody testing and serum creatinine measurement at baseline. PREDICTOR HCV seropositivity. OUTCOMES & MEASUREMENT Estimated glomerular filtration rate (eGFR) calculated from semi-annual serum creatinine measurements using the 4-variable Modification of Diet in Renal Diseases (MDRD) Study equation. Linear mixed models were used to evaluate the independent effect of HCV seropositivity on eGFR over time, adjusting for demographic factors, comorbid conditions, illicit drug use, measures of HIV disease status, use of medications, and interactions with baseline low eGFR (<60 mL/min/1.73 m(2)). RESULTS Of 2,684 HIV-infected women, 952 (35%) were found to be HCV seropositive. In 180 women with chronic kidney disease (CKD) at baseline (eGFR < 60 mL/min/1.73 m(2)), HCV seropositivity was independently associated with a fully adjusted net decrease in eGFR of approximately 5% per year (95% confidence interval, 3.2 to 7.2) relative to women who were seronegative. In contrast, HCV infection was not independently associated with a decrease in eGFR in women without low eGFR at baseline (P < 0.001 for interaction). LIMITATIONS The MDRD Study equation has not been validated as a measure of GFR in persons with HIV or HCV infection. Proteinuria was not included in the study analysis. Because the study is observational, effects of residual confounding cannot be excluded. CONCLUSIONS In HIV-infected women with CKD, coinfection with HCV is associated with a modest, but statistically significant, decrease in eGFR over time. More careful monitoring of kidney function may be warranted for HIV-infected patients with CKD who are also coinfected with HCV.
