Barriers and Facilitators of Hepatitis C Care in Persons Coinfected with Human Immunodeficiency Virus. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:15237. [PMID: 36429957 PMCID: PMC9690547 DOI: 10.3390/ijerph192215237] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Revised: 11/09/2022] [Accepted: 11/13/2022] [Indexed: 06/16/2023]
Abstract
Hepatitis C virus (HCV) and human immunodeficiency virus (HIV) are often co-transmitted. Viral coinfection results in worse outcomes. Persons who inject drugs (PWIDs) face barriers to medical treatment, but HCV treatment is indicated and effective even with ongoing active drug use. We aimed to assess access to HCV care and treatment results in patients coinfected with HIV-HCV. This is a real-world retrospective single-center study of patients followed in the HIV clinic between 2002 and 2018. Linkage to care was defined as achieving care cascade steps: (1) hepatology clinic visit, (2) receiving prescription of anti-HCV treatment, and (3) documentation of sustained virologic response (SVR). Of 1660 patients with HIV, 254 with HIV-HCV coinfection were included. Only 39% of them achieved SVR. The rate limiting step was the engagement into hepatology care. Being a PWID was associated with ~50% reduced odds of achieving study outcomes, active drug use was associated with ~90% reduced odds. Older age was found to facilitate treatment success. Once treated, the rate of SVR was high in all populations. HCV is undertreated in coinfected young PWIDs. Further efforts should be directed to improve access to care in this marginalized population.

Modeling hepatitis C micro-elimination among people who inject drugs with direct-acting antivirals in metropolitan Chicago. PLoS One 2022; 17:e0264983. [PMID: 35271634 PMCID: PMC8912265 DOI: 10.1371/journal.pone.0264983] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Accepted: 02/01/2022] [Indexed: 02/03/2023] Open
Abstract
Hepatitis C virus (HCV) infection is a leading cause of chronic liver disease and mortality worldwide. Direct-acting antiviral (DAA) therapy leads to high cure rates. However, persons who inject drugs (PWID) are at risk for reinfection after cure and may require multiple DAA treatments to reach the World Health Organization's (WHO) goal of HCV elimination by 2030. Using an agent-based model (ABM) that accounts for the complex interplay of demographic factors, risk behaviors, social networks, and geographic location for HCV transmission among PWID, we examined the combination(s) of DAA enrollment (2.5%, 5%, 7.5%, 10%), adherence (60%, 70%, 80%, 90%) and frequency of DAA treatment courses needed to achieve the WHO's goal of reducing incident chronic infections by 90% by 2030 among a large population of PWID from Chicago, IL and surrounding suburbs. We also estimated the economic DAA costs associated with each scenario. Our results indicate that a DAA treatment rate of >7.5% per year with 90% adherence results in 75% of enrolled PWID requiring only a single DAA course; however 19% would require 2 courses, 5%, 3 courses and <2%, 4 courses, with an overall DAA cost of $325 million to achieve the WHO goal in metropolitan Chicago. We estimate a 28% increase in the overall DAA cost under low adherence (70%) compared to high adherence (90%). Our modeling results have important public health implications for HCV elimination among U.S. PWID. Using a range of feasible treatment enrollment and adherence rates, we report robust findings supporting the need to address re-exposure and reinfection among PWID to reduce HCV incidence.

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.

Development of a risk score to guide targeted hepatitis C testing among human immunodeficiency virus patients in Cambodia. World J Hepatol 2021; 13:1167-1180. [PMID: 34630883 PMCID: PMC8473498 DOI: 10.4254/wjh.v13.i9.1167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2021] [Revised: 06/27/2021] [Accepted: 08/24/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The World Health Organization recommends testing all human immunodeficiency virus (HIV) patients for hepatitis C virus (HCV). In resource-constrained contexts with low-to-intermediate HCV prevalence among HIV patients, as in Cambodia, targeted testing is, in the short-term, potentially more feasible and cost-effective.
AIM To develop a clinical prediction score (CPS) to risk-stratify HIV patients for HCV coinfection (HCV RNA detected), and derive a decision rule to guide prioritization of HCV testing in settings where ‘testing all’ is not feasible or unaffordable in the short term.
METHODS We used data of a cross-sectional HCV diagnostic study in the HIV cohort of Sihanouk Hospital Center of Hope in Phnom Penh. Key populations were very rare in this cohort. Score development relied on the Spiegelhalter and Knill-Jones method. Predictors with an adjusted likelihood ratio ≥ 1.5 or ≤ 0.67 were retained, transformed to natural logarithms, and rounded to integers as score items. CPS performance was evaluated by the area-under-the-ROC curve (AUROC) with 95% confidence intervals (CI), and diagnostic accuracy at the different cut-offs. For the decision rule, HCV coinfection probability ≥1% was agreed as test-threshold.
RESULTS Among the 3045 enrolled HIV patients, 106 had an HCV coinfection. Of the 11 candidate predictors (from history-taking, laboratory testing), seven had an adjusted likelihood ratio ≥ 1.5 or ≤ 0.67: ≥ 50 years (+1 point), diabetes mellitus (+1), partner/household member with liver disease (+1), generalized pruritus (+1), platelets < 200 × 109/L (+1), aspartate transaminase (AST) < 30 IU/L (-1), AST-to-platelet ratio index (APRI) ≥ 0.45 (+1), and APRI < 0.45 (-1). The AUROC was 0.84 (95%CI: 0.80-0.89), indicating good discrimination of HCV/HIV coinfection and HIV mono-infection. The CPS result ≥0 best fits the test-threshold (negative predictive value: 99.2%, 95%CI: 98.8-99.6). Applying this threshold, 30% (n = 926) would be tested. Sixteen coinfections (15%) would have been missed, none with advanced fibrosis.
CONCLUSION The CPS performed well in the derivation cohort, and bears potential for other contexts of low-to-intermediate prevalence and little onward risk of transmission(i.e. cohorts without major risk factors as injecting drug use, men having sex with men), and where available resources do not allow to test all HIV patients as recommended by WHO. However, the score requires external validation in other patient cohorts before any wider use can be considered.

Evolution of estimated glomerular filtration rate in human immunodeficiency virus and hepatitis C virus-coinfected patients receiving sofosbuvir-based direct-acting antivirals and antiretroviral therapy. J Viral Hepat 2021; 28:887-896. [PMID: 33759290 DOI: 10.1111/jvh.13502] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Revised: 02/06/2021] [Accepted: 02/26/2021] [Indexed: 12/13/2022]
Abstract
The nephrotoxicity of sofosbuvir (SOF) on human immunodeficiency virus and hepatitis C virus (HIV/HCV)-coinfected patients receiving antiretroviral therapy (ART) remains controversial. We prospectively compared the estimated glomerular filtration rate (eGFR) changes in 167 patients receiving SOF-based direct-acting antivirals (DAAs) who also received tenofovir disoproxil fumarate (TFV)-based (n = 116) and TFV-free ART (n = 51). The eGFR was assessed by the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation, and the eGFR changes between ART regimens were compared by the generalized estimated equation. During DAA treatment, participants on TFV-based ART had a higher eGFR decline than those on TFV-free ART (slope coefficient difference: -0.82 ml/min/1.73 m2 /month [95% CI: -1.21 to -0.43]; p < 0.001), whereas the eGFR changes did not differ between groups (slope coefficient difference: 0.13 ml/min/1.73 m2 /month [95% CI: -0.32 to 0.58]; p = 0.42) after discontinuing DAAs. Participants on TFV TDF-based ART had a higher eGFR decline than those on TFV alafenamide fumarate (TAF)-based ART (slope coefficient difference: -0.31 ml/min/1.73 m2 /month [95% CI: -0.50 to -0.12]; p = 0.01). After discontinuing DAAs, the eGFR changes did not differ between groups (slope coefficient difference: 0.06 ml/min/1.73 m2 /month [95% CI: -0.98 to 1.10]; p = 0.91). In conclusion, HIV/HCV-coinfected patients on TFV-based ART had a slight eGFR decline compared to those on TFV-free ART during SOF-based DAA therapy. A similar trend between TDF-based and TAF-based ART was also observed. Because the differences of eGFR changes are limited, the physicians should not discourage the use of SOF-based DAAs in HIV-positive patients on TFV-based ART.

Abstract
The introduction of clotting factor concentrates has substantially improved the lives of people with clotting factor deficiencies. Unfortunately, the transmission of blood-borne viral infections through these plasma-derived products led to a huge epidemic of human immunodeficiency virus and viral hepatitis in people with haemophilia (PWH). In a significant proportion of PWH exposed to these viruses, the ensuing decades-long chronic infection resulted in excess morbidity and mortality. Fortunately, developments in the safety of blood products, as well as vaccination and highly effective antiviral treatments have improved the prospects of PWH. The present article reviews the background of the viral hepatitis epidemic in PWH, the natural history of hepatitis B and C infections and their long-term management.

Abstract
OBJECTIVES To investigate the effectiveness, safety, and reasons for premature discontinuation of direct-acting antivirals (DAAs) in a diverse population of HIV/hepatitis C virus (HCV) coinfected individuals in Europe. METHODS All HIV/HCV coinfected individuals in the EuroSIDA study that started interferon free DAA treatment between January 6, 2014, and January 3, 2018, with ≥12 weeks of follow-up after treatment stop were included in this analysis. Sustained virological response (SVR) was defined as a negative HCV-RNA result ≥12 weeks after stopping treatment (SVR12). Logistic regression was used to explore factors associated with SVR12. RESULTS 1042 individuals started interferon-free DAA treatment after 1/6/2014 and were included, 862 (82.2%) had a known response to treatment, and 789 [91.5%, 95% confidence interval (CI): 89.7 to 93.4] of which achieved SVR12. There were no differences in SVR12 across regions of Europe (P = 0.84). After adjustment, the odds of achieving SVR12 was lower in individuals that received sofosbuvir/simeprevir ± ribavirin (RBV) [adjusted odds ratio 0.21 (95% CI: 0.08 to 0.53)] or ombitasvir/paritaprevir/dasabuvir ± RBV [adjusted odds ratio 0.46 (95% CI: 0.22 to 1.00)] compared with sofosbuvir/ledipasvir ± RBV. Forty-three (4.6%) individuals had one or more components of their HCV regimen stopped early, most commonly because of toxicity (n = 14); of these 14, 11 were treated with ribavirin. Increased bilirubin was the most common grade 3 or 4 laboratory adverse event (n = 15.3%) and was related to treatment with atazanavir and ribavirin. CONCLUSIONS Our findings from real-world data on HIV/HCV coinfected individuals across Europe show DAA treatment is well tolerated and that high rates of SVR12 can be achieved in all regions of Europe.

National estimates of case-mix, mortality, and economic outcomes among inpatient HIV/AIDS mono-infection and hepatitis C co-infection cases in the US. J Eval Clin Pract 2019; 25:806-821. [PMID: 30485617 DOI: 10.1111/jep.13076] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2018] [Revised: 10/26/2018] [Accepted: 10/29/2018] [Indexed: 12/27/2022]
Abstract
RATIONALE, AIMS, AND OBJECTIVES To assess inpatient clinical and economic outcomes for AIDS/HIV and Hepatitis C (HCV) co-infection in the United States from 2003 to 2014. METHOD This historical cohort study utilized nationally representative hospital discharge data to investigate inpatient mortality, length of stay (LoS), and inflation-adjusted charges among adults (≥18 years). Outcomes were analysed via multivariable generalized linear models according to demographics, hospital and clinical characteristics, and AIDS/HIV or HCV sequelae. RESULTS Overall, 17.8% of the 2.75 million estimated AIDS/HIV inpatient cases involved HCV from 2003 to 2014, averaging 48.5 ± 9.0 years of age and 68.0% being male. Advanced sequalae of AIDS and HCV incurred a LoS of 10.3 ± 11.9 days, charges of $88 789 ± 131 787, and a 16.9% mortality. Many cases involved noncompliance, tobacco use disorders, and substance abuse. Although mortality decreased over time, multivariable analyses indicated that poorer outcomes were generally associated with more advanced clinical conditions and AIDS-associated sequalae, although mixed results were observed for specific manifestations of HCV. Rural residence was independently associated with a 3.26 times higher adjusted odds of mortality from 2009 to 2014 for HIV/HCV co-infection (P < 0.001), although not for AIDS/HCV (OR = 1.38, P = 0.166). CONCLUSION Given the systemic nature and modifiable risks inherent within coinfection, more proactive screening and intervention appear warranted, particularly within rural areas.

Impact of co-infection by hepatitis C virus on immunological and virological response to antiretroviral therapy in HIV-positive patients. Medicine (Baltimore) 2018; 97:e12238. [PMID: 30235668 PMCID: PMC6160110 DOI: 10.1097/md.0000000000012238] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2018] [Accepted: 08/14/2018] [Indexed: 12/12/2022] Open
Abstract
We assessed the effect of co-infection by hepatitis C virus (HCV) on immunological and virological response at 48 weeks from initiation of antiretroviral therapy (ART).We included patients from the Cohort of Spanish HIV Research Network (CoRIS) starting ART between January 2004 and November 2014, had at least 1 CD4 T-cell count and viral load measurements both in the previous 6 months and at 48 (±12) weeks from ART initiation, and HCV serology before ART initiation. We used linear regression for mean differences in CD4 T-cell count increase from ART initiation and logistic regression to estimate odds ratios for virological response.Of 12,239 patients by November 30, 2015, 5070 met inclusion criteria: 4382 (86.4%) HIV mono-infected and 688 (13.6%) HIV/HCV co-infected. Co-infected patients were more likely to have acquired HIV through injecting drugs use (57.4% vs. 1.1%), to be women, older, and Spanish, have a lower educational level, and having started ART with lower CD4 counts and acquired immunodeficiency syndrome. CD4 T-cell count increase at 48 weeks was 229.7 cell/μL in HIV-monoinfected and 161.9 cell/μL in HIV/HCV-coinfected patients. The percentages of patients achieving a virological response at 48 weeks were 87.0% and 78.3% in mono and coinfected patients, respectively. Multivariable analyses showed that at 48 weeks, coinfected patients increased 44.5 (95% confidence interval [CI]: 24.8-64.3) cells/μL less than monoinfected and had lower probability of virological response (odds ratio: 0.62; 95% CI: 0.44-0.88).HIV/HCV-coinfected patients have lower immunological and virological responses at 48 weeks from ART initiation than monoinfected patients.

Abstract
INTRODUCTION Concomitant use of ledipasvir and boosted protease inhibitors (PIs) may increase the risk of tenofovir (TDF) nephrotoxicity, since both these drugs increase TDF levels. Our aim was to evaluate glomerular filtration rate (eGFR) evolution during HCV treatment with sofosbuvir/ledipasvir (SOF/LDV) in HCV/HIV coinfected patients, according to their antiretroviral treatment (ARV). METHODS Observational prospective study of HCV/HIV coinfected patients treated with SOF/LDV. eGFR evolution was evaluated during and 12 weeks after HCV treatment. Patients were categorized in three groups based on ARV regimen: non TDF, non-boosted TDF and TDF + boosted PI. RESULTS We included 273 patients: 145 were receiving a non-TDF regimen, 78 a non-boosted TDF scheme and 50 were receiving TDF + boosted PI. We observed a statistically significant decrease in eGFR during treatment in all groups (non TDF p = 0.03, 95%CI [0.23-3.86], non-boosted TDF p < 0.01, 95%CI [3.36-7.44], TDF + PI p = 0.01, 95%CI [1.09-7.53]). The decrease was more pronounced in those receiving unboosted TDF (- 5.40 ml/min/1.73m2), but differences in eGFR decrease between the three groups were small and not statistically different (p = 0.06). eGFR decrease was greater in patients treated for 24 weeks (p = 0.009) and in cirrhotic patients (p = 0.036). At the end of follow up a recovery of eGFR was observed in all groups. CONCLUSION We observed a significant decrease in eGFR during treatment in all study groups, that was small and reversible after SOF/LDV discontinuation. TDF was not associated with an increase in renal toxicity.

Abstract
Real-time PCR assays for nucleic acid testing (NAT) of hepatitis viruses A-E and for HIV-1 and HIV-2 have been developed; however, a multiplex assay that can simultaneously detect all of these agents is not yet available. Standardized TaqMan assays for detection of hepatitis viruses A-E have been described and applied to TaqMan Array Cards (TAC) which are capable of multiple pathogen detection using a single set of optimized PCR conditions. Assays for three gene regions of HIV-1 (long-terminal repeat (LTR), gag, and polymerase) and HIV-2 (overlap of LTR and gag, protease and integrase) were designed using the hepatitis assay conditions. Nucleic acid extracts of HIV-1-infected samples (44 plasma, 41 whole blood, 20 HIV-1 viral stocks) were tested on the TAC cards; 98 were reactive (92%) with 70 in multiple gene regions. Twenty-four of the 27 (89%) HIV-2 specimens (10 plasma, 1 PBMC lysate, 6 whole blood and 10 plasmids containing HIV-2 polymerase) were detected on TAC. No HIV or hepatitis virus sequences were detected in 30 HIV-negative samples (specificity 100%). Three HBV and 18 HCV co-infections were identified in the HIV-1-infected specimens. Multi-pathogen detection using TAC could provide a rapid, sensitive and more efficient method of surveying for a variety of infectious disease nucleic acids.

Abstract
INTRODUCTION The hepatitis C virus (HCV) has affected an estimated of 80 million individuals worldwide and is a strain on public health. Around 25-30% of patients in Europe and the US who are infected with HIV are coinfected with HCV. Prior to 2013, treatment modalities containing an NS3/4A protease inhibitor in combination with pegylated interferon and ribavirin improved sustained virological response (SVR) rates. However, rates of severe side effects were high. Nowadays, oral direct-acting antiviral (DAA) combination therapy offers excellent treatment efficacy, safety and tolerability. AREAS COVERED This review focuses on the current literature and clinical evidence and their impact regarding NS3/4A protease inhibitors. The pitfalls encountered in treating HIV- and HBV-coinfected patients are also discussed. EXPERT OPINION In the era of DAA treatment, third-generation pan-genotypic NS3/4A protease inhibitors (mainly glecaprevir and voxilaprevir) show high antiviral activity and a genetic resistance barrier with cure rates of over 95% when combined with an NS5A inhibitor, irrespective of baseline resistance associated variants (RASs) being present. These new key components of DAA combination therapy are impressive options to eradicate HCV in the so-called difficult-to-treat population (e.g. compensated cirrhosis, end-stage renal disease and patients who failed previous DAA treatment).

Abstract
BACKGROUND & AIMS Mucosal-associated invariant T (MAIT) cells are important innate T cells with antimicrobial and immunoregulatory activity, recently found to be depleted in blood of patients with HIV and HCV mono-infections. In this study, we assessed the impact of HIV, HCV and HCV/HIV co-infection on circulating and intrahepatic MAIT-cells and correlations with liver fibrosis. METHODS In this cross-sectional study, nine healthy subjects, nine HIV, 20 HCV and 22 HCV/HIV co-infected patients were included. Blood and liver fine needle aspirate biopsies were studied using flowcytometry for CD3+ CD161+ Vα7.2+ MAIT-cell frequency, phenotype and function in HCV mono-infected and HCV/HIV co-infected patients without or with mild fibrosis (Metavir-score F0-F1) or severe fibrosis to cirrhosis (Metavir-score F3-F4). RESULTS Circulating MAIT-cells were decreased in blood of HCV, HIV and HCV/HIV patients with F0-F1. In HCV/HIV co-infected individuals with severe fibrosis to cirrhosis, the frequency of circulating MAIT-cells was even further depleted, whereas their function was comparable to HCV/HIV co-infected patients with low or absent fibrosis. In contrast, in HCV mono-infected patients, MAIT-cell frequencies were not related to fibrosis severity; however, MAIT-cell function was impaired in mono-infected patients with more fibrosis. More advanced liver fibrosis in HCV or HCV/HIV-infected patients was not reflected by increased accumulation of MAIT-cells in the affected liver. CONCLUSIONS Severe liver fibrosis is associated with dysfunctional MAIT-cells in blood of HCV mono-infected patients, and lower MAIT frequencies in blood of HCV/HIV co-infected patients, without evidence for accumulation in the liver.

Abstract
This study aimed to assess attitudes and potential barriers towards treatment in patients with hepatitis C virus (HCV) infection, comparing those with and without HIV coinfection. A cross-sectional survey of 82 HCV-infected adults with and without HIV was conducted in greater Los Angeles between November 2013 and July 2015. Overall, there were 53 (64.6%) with HIV coinfection, 20 (25.0%) with self-reported cirrhosis, and 22 (26.8%) with a history of prior HCV treatment. Of all, 93.2% wanted HCV treatment, but 45.9% were unwilling/unable to spend anything out of pocket, 29.4% were waiting for new therapies, and 23.5% were recommended to defer HCV treatment. HIV/HCV-coinfected patients were more likely to want treatment within one year (90.2% versus 68.2%, p = 0.02), more willing to join a clinical trial (74.5% versus 8.0%, p < 0.01), more willing to take medications twice daily (86.3% versus 61.5%, p = 0.01), and more likely to prefer hepatitis C treatment by an infectious diseases/HIV physician (36.7% versus 4.0%, p < 0.01). Of all, 77.1% of coinfected patients were willing to change antiretroviral therapy if necessary to treat HCV, but only 48.0% of patients were willing to take a medication if it had not been studied in HIV-positive patients. Treatment preferences differ between HIV/HCV-coinfected and HCV-monoinfected patients. Despite a strong willingness among the study cohort to start HCV treatment, other factors such as cost, access to medications, and provider reluctance may be delaying treatment initiation.

Abstract
OBJECTIVE In Thailand, 7.2% of HIV patients are co-infected with hepatitis C virus (HCV), and these patients are treated with peg-interferon + ribavirin (PR) for their HCV infection. This study evaluates efficacy and safety of PR treatment and pharmacokinetics of ribavirin in this population. METHODS HIV/HCV co-infected Thai patients were treated with PR for 24 or 48 weeks. Sustained virological response 24 weeks after the end of treatment (SVR24) was used to describe efficacy. (laboratory) safety parameters and ribavirin plasma concentrations were evaluated during study visits. Ribavirin concentrations were compared with t-tests for patients with and without anaemia (haemoglobin <10 g/dl) and SVR24. RESULTS A total of 101 HIV/HCV co-infected patients were included; 88% were male (n = 88), and 46% were infected with genotype 3. The median (IQR) start dose was 14.28 mg/kg/day. SVR24 rate was 56%. All patients reported at least one (serious) adverse event, of which 28% of patients developed anaemia. Seven patients discontinued treatment due to toxicity issues. Geometric mean (IQR) ribavirin concentration was 1.81 (1.42-2.32) mg/l at week 8 of treatment. At week 8, patients with and without anaemia and SVR had ribavirin concentrations of 2.29 and 1.63 mg/l and 1.91 and 1.74 mg/l, respectively. CONCLUSIONS PR treatment has comparable response rates and toxicity profile in Thai HIV/HCV co-infected patients as in Western HIV/HCV patients. However, ribavirin plasma concentrations were comparable with previously published studies in HIV/HCV co-infected patients, but both, just as SVR rate, were lower than in mono-infected patients.

Abstract
BACKGROUND Direct acting antivirals are expected to drastically reduce the burden of hepatitis C virus (HCV) in people living with Human Immunodeficiency Virus (HIV). However, rates of HCV testing, re-testing and incident infection in this group remain uncertain in Australia. We assessed trends in HCV testing, re-testing and incident infection among HIV-positive individuals, and evaluated factors associated with HCV re-testing and incident infection. METHODS The study population consisted of HIV-positive individuals who visited a sexual health service involved in the Australian Collaboration for Coordinated Enhanced Sentinel Surveillance (ACCESS) between 2007 and 2015. Poisson regression was used to assess trends and to evaluate factors associated with HCV re-testing and incident HCV infection. RESULTS There were 9227 HIV-positive individuals included in our testing rate analysis. Of 3799 HIV-positive/HCV-negative people that attended an ACCESS sexual health service more than once, 2079 (54.7%) were re-tested for HCV and were therefore eligible for our incidence analysis. The rate of HCV testing increased from 17.1 to 51.4 tests per 100 patient years between 2007 and 2015 (p for trend <0.01). Over the same period, HCV re-testing rates increased from 23.9 to 79.7 tests per 100 person years (p for trend <0.01). A clear increase in testing and re-testing began after 2011. Patients who identified as men who have sex with men and those with a history of injecting drug use experienced high rates of HCV re-testing over the course of the study period. Among those who re-tested, 157 incident HCV infections occurred at a rate of 2.5 events per 100 person years. Between 2007 and 2009, 2010-2011, 2012-2013 and 2014-2015, rates of incident HCV were 0.8, 1.5, 3.9 and 2.7 events per 100 person years, respectively (p for trend <0.01). Incident HCV was strongly associated with a history of injecting drug use. CONCLUSIONS High rates of HCV testing and re-testing among HIV-positive individuals in Australia will assist strategies to achieve HCV elimination through rapid treatment scale up. Continued monitoring of HCV incidence in this population is essential for guiding both HCV prevention and treatment strategies.

Around 25-30% of patients in Europe and the US infected with HIV are coinfected with HCV. Despite treatment modalities containing a NS3/4A protease inhibitor in combination with pegylated interferon and ribavirin prior to 2013 improved SVR rates, the amount of severe side effects was high. Nowadays, oral direct-acting antivirals (DAAs) combination therapy offers excellent treatment efficacy, safety and tolerability. This review focuses on current literature and clinical evidence and their impact regarding NS3/4A protease inhibitors. In addition, pitfalls in treatment from HIV- and HBV-coinfected patients will also be discussed. In the era of DAA treatment, the third-generation pan-genotypic NS3/4A protease inhibitors (mainly grazoprevir, glecaprevir and voxilaprevir) show a high antiviral activity and genetic resistance barrier with cure rates of over 95% when combined with an NS5A inhibitor, irrespectively of baseline resistance associated variants (RASs) being present. These new key components of DAA combination therapy are impressive options to eradicate HCV in the so called difficult-to-treat population (e.g. compensated cirrhosis, end-stage renal disease and patients who failed previous DAA treatment).

Abstract
PURPOSE OF REVIEW Availability of direct acting antivirals (DAAs) that demonstrate remarkable clinical efficacy and safety has revolutionized the ability to treat chronic infection with hepatitis C virus (HCV). An equal measure of clinical success has now been achieved in persons coinfected with HCV and the HIV, a historically harder to cure cohort with interferon-based therapy. Global goals include identifying all HIV-HCV-infected persons, gaining access to DAA therapy, preventing de novo and reinfection, and managing the sequelae of chronic infection. This review will discuss advances in the field of HIV-HCV coinfection reported during the last 18 months, and will suggest areas for future investigation. RECENT FINDINGS An expanding body of literature has enhanced our understanding of the clinical and epidemiologic issues surrounding HIV-HCV coinfection. DAA therapy for HCV is highly efficacious in HIV-HCV-coinfected persons if drug-drug interactions are appropriately considered. SUMMARY Eradicating HCV infection in persons with HIV coinfection can be achieved safely and effectively with available DAAs. Economic and social approaches to enable access and delivery of curative HCV therapy to HIV-infected persons require continued research and resource allocation.

HCV coinfection contributes to HIV pathogenesis by increasing immune exhaustion in CD8 T-cells. PLoS One 2017; 12:e0173943. [PMID: 28323897 PMCID: PMC5360268 DOI: 10.1371/journal.pone.0173943] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2016] [Accepted: 03/01/2017] [Indexed: 11/23/2022] Open
Abstract
Background There are several contributors to HIV-pathogenesis or insufficient control of the infection. However, whether HIV/HCV-coinfected population exhibits worst evolution of HIV-pathogenesis remains unclear. Recently, some markers of immune exhaustion have been proposed as preferentially upregulated on T-cells during HIV-infection. Herein, we have analyzed T-cell exhaustion together with several other contributors to HIV-pathogenesis that could be affected by HCV-coinfection. Patients and methods Ninety-six patients with chronic HIV-infection (60 HIV-monoinfected and 36 HIV/HCV-coinfected), and 20 healthy controls were included in the study. All patients were untreated for both infections. Several CD4 and CD8 T-cell subsets involved in HIV-pathogenesis were investigated. Non-parametric tests were used to establish differences between groups and associations between variables. Multivariate linear regression was used to ascertain the variables independently associated with CD4 counts. Results HIV-patients presented significant differences compared to healthy controls in most of the parameters analyzed. Both HIV and HIV/HCV groups were comparable in terms of age, CD4 counts and HIV-viremia. Compared to HIV group, HIV/HCV group presented significantly higher levels of exhaustion (Tim3+PD1- subset) in total CD8+ T-cells (p = 0.003), and higher levels of exhaustion in CD8+HLADR+CD38+ (p = 0.04), CD8+HLADR-CD38+ (p = 0.009) and CD8+HLADR-CD38- (p = 0.006) subsets of CD8+ T-cells. Interestingly these differences were maintained after adjusting by CD4 counts and HIV-viremia. Conclusions We show a significant impact of HCV-coinfection on CD8 T-cells exhaustion, an important parameter associated with CD8 T-cell dysfunction in the setting of chronic HIV-infection. The relevance of this phenomenon on immunological and/or clinical HIV progression prompts HCV treatment to improve management of coinfected patients.

Abstract
The aim of the study was to characterize HCV infection in Northwest Spain and assess the impact of the Spanish Strategic Plan to cure HCV infection. Overall, 387 patients were included (60.9% HIV/HCV coinfected and 28.2% cirrhotic). Of these, 72.9% of patients that were recognized as priority for HCV treatment according to the Spanish Strategic Plan (≥F2, transplant or extrahepatic manifestations), initiated treatment during 2015. Globally, SVR12 was achieved in 96.5% of patients. The implementation of the Spanish Strategic Plan has been critical to advance in HCV cure, but 27.1% of priority patients still remain awaiting HCV treatment initiation.

HCV co-infection and markers of liver injury and fibrosis among HIV-positive childbearing women in Ukraine: results from a cohort study. BMC Infect Dis 2016; 16:755. [PMID: 27955711 PMCID: PMC5153905 DOI: 10.1186/s12879-016-2089-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2016] [Accepted: 12/03/2016] [Indexed: 12/18/2022] Open
Abstract
Background Ukraine’s injecting drug use-driven HIV epidemic is among the most severe in Europe with high burden of HCV co-infection. HIV/HCV co-infected individuals are at elevated risk of HCV-related morbidity, but little is known about burden of liver disease and associated factors in the HIV-positive population in Ukraine, particularly among women. Methods Characteristics of 2050 HIV-positive women enrolled into the Ukrainian Study of HIV-infected Childbearing Women were described by HCV serostatus. Aspartate transaminase (AST) to platelet ratio (APRI) and FIB-4 scores were calculated and exact logistic regression models fitted to investigate factors associated with significant fibrosis (APRI >1.5) among 762 women with an APRI score available. Results Of 2050 HIV-positive women (median age 27.7 years, IQR 24.6-31.3), 33% were HCV co-infected (79% of those with a history of injecting drug use vs 23% without) and 17% HBsAg positive. A quarter were on antiretroviral therapy at postnatal cohort enrolment. 1% of the HIV/HCV co-infected group had ever received treatment for HCV. Overall, 24% had an alanine aminotransferase level >41 U/L and 34% an elevated AST (53% and 61% among HIV/HCV co-infected). Prevalence of significant fibrosis was 4.5%; 2.5% among 445 HIV mono-infected and 12.3% among 171 HIV/HCV co-infected women. 1.2% had a FIB-4 score >3.25 indicating advanced fibrosis. HCV RNA testing in a sub-group of 56 HIV/HCV co-infected women indicated a likely spontaneous clearance rate of 18% and predominance of HCV genotype 1, with one-third having genotype 3 infection. Factors associated with significant fibrosis were HCV co-infection (AOR 2.53 95%CI 1.03-6.23), history of injecting drug use (AOR 3.51 95%CI 1.39-8.89), WHO stage 3-4 HIV disease (AOR 3.47 95%CI 1.51-7.99 vs stage 1-2 HIV disease) and not being on combination antiretroviral therapy (AOR 3.08 95%CI 1.23-7.74), adjusted additionally for HBV co-infection, smoking and age. Conclusions Most HIV/HCV co-infected women had elevated liver enzymes and 12% had significant fibrosis according to APRI. Risk factors for liver fibrosis in this young HIV-positive population include poorly controlled HIV and high burden of HCV. Results highlight the importance of addressing modifiable risk factors and rolling out HCV treatment to improve the health outcomes of this group.

Abstract
INTRODUCTION The sofosbuvir (SOF) plus ledipasvir (LDV) fixed dose combination is the first direct action antiviral (DAA) single-treatment regimen (STR) to be commercialized. It is approved for the treatment of Hepatitis C virus (HCV) genotypes 1,3,4,5 and 6. Following approval in 2014, new pharmacokinetics and pharmacodynamics data were reported, which led to important clinical applications. Areas covered: This article reviews the pharmacokinetic and pharmacodynamic properties of the SOF/LDV fixed dose combination for the treatment of HCV. The topics covered include data regarding the drug´s absorption, distribution, metabolism and excretion and antiviral activity strategies such as the clinical dose selection and treatment duration. Expert opinion: The SOF/LDV fixed dose combination has good pharmacological properties that lead to a high sustained virological response after 12 or 24 weeks of treatment; there is minimal interference with other drugs or associated renal or hepatic impairment, such that dose adjustment is not necessary.

Abstract
HIV-HCV co-infection mostly affects intravenous drug users, in whom prevalence has tended to decrease in recent years, while it has increased in men who have sex with men, with occurrence of acute hepatitis C. Hepatitis C has a poorer prognosis in patients co-infected with HIV, as clinical progression is faster and degree of hepatic fibrosis is greater. However, optimized ARV treatment is clearly associated with slower progression to hepatic complications. Interactions between HCV and HIV drugs are numerous, which underlines the importance of pharmacological advice for HIV-treated patients before they start HCV treatment. In HIV-HCV co-infection, treatment of hepatitis C has to be offered as in mono-infected patients (US and European countries) or to all patients (French guidelines). In most patients, HCV eradication is achieved with different DAA associations, the choice and duration being driven by HCV genotype, hepatic fibrosis stage, and whether patients have been previously treated or not.

Abstract
BACKGROUND Fibrosis progression varies markedly in hepatitis C virus (HCV)-infected individuals. We investigated factors that influence fibrosis progression in chronic HCV infection. METHODS HCV-infected patients who underwent at least 2 liver biopsies were included in this study. Associations between fibrosis progression and epidemiologic, virologic, and disease-associated factors were analyzed using logistic regression and multistate Markov modeling. RESULTS We analyzed 936 biopsy specimens obtained from 378 individuals. Mean age (±SD) at first biopsy was 48.3 ± 9.3 years, 59.3% of patients were male, 59.9% were white, and 86.7% were infected with HCV genotype 1. Fibrosis progression and cirrhosis occurred in 57.4% and 5.8%, respectively. Fibrosis progression between the first and last biopsies was associated with lower fibrosis in the first biopsy specimen (P < .001) and with the occurrence of at least 1 flare in the alanine aminotransferase (ALT) level (>200 U/L; P = .007). We found the highest fibrosis progression rate between stages 0 and 1 and the lowest between stages 2 and 3. Increased necroinflammation and higher ALT level were associated with faster progression. HCV genotype 3-infected patients were more likely to progress to cirrhosis (P < .001). CONCLUSIONS Fibrosis progression in HCV is not linear but varies according to stage, with the highest progression in patients with the lowest fibrosis severity. Patients who experience flares in the ALT level are also more likely to progress.

Abstract
INTRODUCTION Hepatitis C virus (HCV) infection is common in patients with inherited bleeding disorders treated with clotting factor concentrates prior to the introduction of viral inactivation of these products. The long-term consequences of hepatitis C infection in Swedish patients are not fully understood. AIM To examine the impact of HCV infection on liver-related morbidity and mortality in Swedish patients with inherited bleeding disorders. METHODS We retrospectively collected data on 183 patients with inherited bleeding disorders infected with HCV who attended the Coagulation Unit at Karolinska University Hospital, Sweden. Data regarding end-stage liver disease (ESLD), defined as presence of ascites, encephalopathy, variceal bleeding, hepatocellular carcinoma or liver-related death, were collected from the patient records and the national registers. RESULTS The median follow-up time was 35.9 years (IQR 29.0-41.2). A total of 41% had achieved sustained virological response (SVR) after treatment. In total, 14.2% developed ESLD at the median age of 52.6 years (IQR 46.5-64.7). Nineteen (35.8%) of all deaths were due to liver-related causes. Co-infection with human immunodeficiency virus (HIV), older age at time of infection and severe form of bleeding disorder was associated with higher risk of developing ESLD, while SVR was a strong protective factor. CONCLUSIONS This study demonstrated that liver-related morbidity and mortality was significant in patients with bleeding disorders and HCV infection in Sweden. Patients with HCV-infection should be candidates for treatment with the new highly effective antiviral drugs, since SVR proved to be a strong protective factor.

Abstract
The advances in management of patients with acquired immunodeficiency syndrome (AIDS) with highly effective anti-retroviral therapy (HAART) have resulted in increased longevity of patients with human immunodeficiency virus (HIV) infection. AIDS-related illnesses now account for less than 50 % of the deaths, and liver diseases have emerged as the leading cause of death in patients with HIV infection. Chronic viral hepatitis, drug-related hepatotoxicity, non-alcoholic fatty liver disease, and opportunistic infections are the common liver diseases that are seen in HIV-infected individuals. Because of the shared routes of transmission, co-infections with hepatitis B virus (HBV) and hepatitis C virus (HCV) are very common in HIV-infected persons. Hepatitis C is the most common viral hepatitis seen in HIV-infected patients. With the availability of directly acting agents, treatment outcome of HCV is comparable to that seen in non HIV-infected patients. Careful monitoring is required for drug interactions and drug-induced hepatotoxicity and modification of drugs should be done where necessary. The results of liver transplantation in select HIV-infected patients can be comparable with those of HIV-negative patients.

Abstract
India contributes significantly to the global burden of HCV. While the nucleoside NS5B inhibitor sofosbuvir became available in the Indian market in March 2015, the other directly acting agents (DAAs), Ledipasvir and Daclatasvir, have only recently become available in the India. The introduction of these DAA in India at a relatively affordable price has led to great optimism about prospects of cure for these patients as not only will they provide higher efficacy, but combination DAAs as all-oral regimen will result in lower side effects than were seen with pegylated interferon alfa and ribavirin therapy. Availability of these newer DAAs has necessitated revision of INASL guidelines for the treatment of HCV published in 2015. Current considerations for the treatment of HCV in India include the poorer response of genotype 3, nonavailability of many of the DAAs recommended by other guidelines and the cost of therapy. The availability of combination DAA therapy has simplified therapy of HCV with decreased reliance of evaluation for monitoring viral kinetics or drug related side effects.

Abstract
HIV-1 infected patients who acquire HCV infection have higher rates of chronicity and liver disease progression than patients with HCV mono-infection. Understanding early events in this pathogenic process is important. We applied single genome sequencing of the E1 to NS3 regions and viral pseudotype neutralization assays to explore the consequences of viral quasispecies evolution from pre-seroconversion to chronicity in four co-infected individuals (mean follow up 566 days). We observed that one to three founder viruses were transmitted. Relatively low viral sequence diversity, possibly related to an impaired immune response, due to HIV infection was observed in three patients. However, the fourth patient, after an early purifying selection displayed increasing E2 sequence evolution, possibly related to being on suppressive antiretroviral therapy. Viral pseudotypes generated from HCV variants showed relative resistance to neutralization by autologous plasma but not to plasma collected from later time points, confirming ongoing virus escape from antibody neutralization.

Abstract
HCV coinfection has emerged as a major cause of non-AIDS-related morbidity and mortality in HIV-positive patients. As a consequence of the availability of modern combined antiretroviral therapy regimens, for optimally managed HIV/HCV-coinfected patients, the rates of liver fibrosis progression and the risk of liver-related events are increasingly similar to those of HCV-monoinfected patients. Moreover, our understanding of modulators of liver disease progression has greatly improved. In addition to immune status, endocrine, metabolic, genetic and viral factors are closely interrelated and might be important determinants of liver disease progression. In the last decade, a variety of serologic and radiographic tests for noninvasive liver disease staging have been extensively validated and are commonly used in HIV/HCV-coinfected patients. Sustained virologic response prevents end-stage liver disease, hepatocellular carcinoma, and death, with an even greater effect size in HIV-positive compared to HIV-negative patients. As interferon-free regimens achieve comparable rates of sustained virologic response in HIV-negative and HIV-positive patients, HIV/HCV-coinfected patients should from now on be referred to as a special, rather than a difficult-to-treat, population. Our comprehensive review covers all relevant aspects of HIV/HCV coinfection. Beginning with the changing epidemiology, it also provides new insights into the natural history of this condition and gives an overview on non-invasive techniques for the staging of liver disease. Furthermore, it outlines current recommendations for the treatment of acute hepatitis C and summarizes the unprecedented advances in the field of chronic hepatitis C therapy.
