Abstract
PURPOSE Hepatitis C virus (HCV) infection remains a major health problem and one of the leading causes of chronic liver disease worldwide. The purpose of this paper was to summarize knowledge about the epidemiology of HCV genotype (GT) 4 infection, similarities and differences with other genotypes, specific problems associated with this genotype, and treatment regimens used to treat GT4-infected patients. METHODS We performed an accurate search for literature using the PubMed database to select high-quality reviews and original articles concerning this topic. RESULTS GT4 with a global prevalence of 8% takes third place, closing the global HCV podium in terms of frequency. However, there are regions where GT4 infections are dominant, such as sub-Saharan and North Africa, and the Middle East. The disease course and complications are generally similar to those of chronic hepatitis C caused by other genotypes, although the faster progression of fibrosis was demonstrated in patients with coexisting schistosomiasis. In the era of interferon-based therapy, GT4-infected patients were described as difficult to treat due to suboptimal response. A breakthrough in the treatment of HCV-infected patients, including those with GT4 infection, was the introduction of direct-acting antiviral drugs. CONCLUSIONS The availability of safe and effective therapy has created a real opportunity for HCV eradication in line with the goal set by the World Health Organization. An example of a country where this is happening is Egypt, where GT4 accounts for more than 90% of HCV infections. There, broad access to therapy has been effectively supported by population-based screening.

Metabolomic changes after DAAs therapy are related to the improvement of cirrhosis and inflammation in HIV/HCV-coinfected patients. Pharmacotherapy 2022; 147:112623. [PMID: 35032770 DOI: 10.1016/j.biopha.2022.112623] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 01/05/2022] [Accepted: 01/05/2022] [Indexed: 12/21/2022]
Abstract
BACKGROUND A better understanding of the evolution of cirrhosis after hepatitis C virus (HCV) clearance is essential since the reversal of liver injury may not happen. We aimed to assess the evolution of plasma metabolites after direct-acting antivirals (DAAs) therapy and their association with liver disease scores in HIV/HCV-coinfected patients with advanced HCV-related cirrhosis. METHODS We performed a prospective study in 49 cirrhotic patients who started DAAs therapy. Data and samples were collected at baseline and 36 weeks after SVR. Metabolomics analysis was carried out using gas chromatography-mass spectrometry and liquid chromatography-mass spectrometry. Inflammation-related biomarkers were analyzed using ProcartaPlex Immunoassays. RESULTS At 36 weeks after SVR, patients experienced significant decrease in taurocholic acid, 2,3-butanediol, and LPC(18:0); while several phosphatidylcholines (LPC(16:1), LPC(18:1), LPC(20:4), and PC(16:0/9:0(CHO))/PC(16:0/9:0(COH)), 2-keto-n-caproic acid/2-keto-isocaproic acid and N-methyl alanine increased, compared to baseline. The plasma decrease in taurocholic acid was associated with a reduction in Child-Turcotte-Pugh (CTP) (AMR=3.39; q-value=0.006) and liver stiffness measurement (LSM) (AMR=1.06; q-value<0.001), the plasma increase in LPC(20:4) was related to a reduction in LSM (AMR=0.98; q-value=0.027), and the rise of plasma 2-keto-n-caproic acid/2-keto-isocaproic acid was associated with a reduction in CTP (AMR=0.35; q-value=0.004). Finally, plasma changes in taurocholic acid were directly associated with inflammation-related biomarkers, while changes in LPC(20:4) were inversely associated. CONCLUSIONS Plasma metabolomic profile changed after HCV clearance with all oral-DAAs in HIV/HCV-coinfected with advanced HCV-related cirrhosis. Changes in plasma levels of LPC (20: 4), 2-keto-n-caproic acid/2-keto-isocaproic acid, and taurocholic acid were related to improvements in cirrhosis scores and inflammatory status of patients.

Abstract
BACKGROUND & AIMS Despite a marked reduction in new cases of cirrhosis caused by HCV infection, over 500,000 new cirrhosis cases in this category were estimated globally in 2019. This contribution quantifies the relationship between alcohol use and the progression of liver disease in people with HCV infections. METHODS The causal impact of different levels of alcohol use on cirrhosis has previously been established. The quantification of this relationship was undertaken based on a systematic search of the literature and a meta-analysis. We limited our search to longitudinal and case-control studies with biologically verified outcomes. Different sensitivity analyses were conducted to check on key assumptions and on the generalizability of the relationship. RESULTS Alcohol use has a dose-dependent relationship with incident cirrhosis, which is linear on the log-linear level, and thus exponential on the level of odds ratios or other risk indicators. Each standard drink of 12 grams of pure alcohol per day increases the risk by about 11%. The results were stable regardless of the statistical model used, level of adjustment, quality of the study, or outcome (i.e., cirrhosis, decompensated cirrhosis, liver-related death). CONCLUSIONS Alcohol use has a marked impact on the progression of HCV infections to cirrhosis and more severe liver outcomes. LAY SUMMARY Alcohol consumption has a significant impact on the progression of liver disease in people with HCV infections. Each alcoholic drink per day is associated with an increase in the risk of cirrhosis of 11%.

Abstract
HIV coinfection is associated with more rapid liver fibrosis progression in hepatitis C (HCV) infection. Recently, much work has been done to improve outcomes of liver disease and to identify targets for pharmacological intervention in coinfected patients. In this study, we analyzed clinical data of 1,858 participants from the Women's Interagency HIV Study (WIHS) to characterize risk factors associated with changes in the APRI and FIB-4 surrogate measurements for advanced fibrosis. We assessed 887 non-synonymous single nucleotide variants (nsSNV) in a subset of 661 coinfected participants for genetic associations with changes in liver fibrosis risk. The variants utilized produced amino acid substitutions that either altered an N-linked glycosylation (NxS/T) sequon or mapped to a gene related to glycosylation processes. Seven variants were associated with an increased likelihood of liver fibrosis. The most common variant, ALPK2 rs3809973, was associated with liver fibrosis in HIV/HCV coinfected patients; individuals homozygous for the rare C allele displayed elevated APRI (0.61, 95% CI, 0.334 to 0.875) and FIB-4 (0.74, 95% CI, 0.336 to 1.144) relative to those coinfected women without the variant. Although warranting replication, ALPK2 rs3809973 may show utility to detect individuals at increased risk for liver disease progression.

Abstract
Hepatitis infection in HIV positive individuals with liver diseases causes high mortality worldwide. HIV worsens the pathological effect of hepatitis viruses and potentiates reactivation of latent hepatitis infections due to reduced immunity. This research therefore aimed to study the occurrence of HIV and hepatitis viruses among liver diseases patients (LVDP) attending tertiary hospitals in Osun State, southwestern Nigeria. A total of 121 LVDP blood samples collected were tested for HIV and Hepatitis B, C, and E using and enzyme linked Immunossorbent assay (ELISA). Data were analyzed using packages within SPSS and P ≤ 0.05 was considered significant. Prevalence of 32.2%, 0.8%, 10.7%, and 18.2% for HBsAg, Anti-HCV, HEV-IgM, and HIV were found respectively. Marital status showed a significant association with HEV-IgM infection (χ2 = 9.869, P = .020). The prevalence of HBsAg, HEV, and HIV among LVDP in Osun State is alarming and health education among the patients and general populace is hereby advocated. High HEV-IgM seroprevalence implies that HEV routine screening should be incorporated into blood screening. Since HEV is associated with unhygienic practice, people should be enlightened on how to improve their living conditions.

Abstract
AIM More than 1400 Japanese hemophiliacs acquired HIV infection around 1983 through contaminated blood products imported from the USA, most of whom also acquired hepatitis C virus (HCV) infection. To delineate the HCV genetic relations in HIV-coinfected hemophiliacs, we analyzed stocked plasma samples of the patients seen at the largest referral center for HIV care in Japan. METHODS Hepatitis C virus full-genome sequences were amplified and determined using next-generation sequencing, and genotyping and phylogenetic analyses of these sequences were carried out. The results of these hemophiliacs were compared with those of previously studied HIV-coinfected Japanese non-hemophiliacs who had undergone similar analysis of HCV full-genome sequences. RESULTS From 1997 to the end of 2017, 72 HIV-infected Japanese hemophiliacs regularly visited our outpatient clinic. Of these, 51 patients had detectable plasma HCV-RNA. The HCV full genome was successfully amplified and sequenced in 50 patients. Not only HCV genotypes 1b (28%) and 2a (6%), which are common in Japan, but also HCV genotypes 1a (32%) and 3a (22%) were identified at high frequency. A single case of intergenotypic recombinant form (2b/1a) and a single case of mixed infection (1a and 3a) were also identified. Each sequence derived from hemophiliacs was more than 0.05 genetic distance away from the other sequences in phylogenetic analysis. CONCLUSIONS Various HCV genotypes were identified in Japanese hemophiliacs, a finding that reflects the HCV genotypic distribution in the USA. The genetic distance among them are the results of viral evolution in each patient plus HCV genetic diversity in the USA.

Abstract
OBJECTIVE To evaluate the progression of liver stiffness after treatment with direct antiviral agents (DAAs), to identify predictive factors of fibrosis regression and to analyze the changes of scores AST-to-platelet ratio index (APRI) and Fibrosis-4 (FIB-4) after treatment. DESIGN Multicenter prospective cohort study of HIV/HCV co-infected patients conducted within the GECMEI cohort, Spain. METHODS Individuals were eligible if they were willing to start DAAs and underwent two transient elastographies: at baseline and after the end of treatment (EOT). All patients with detectable HCV RNA naïve to DAAs were consecutively enrolled from nine medical hospitals. Liver stiffness results were categorized in four Metavir stages (F1: <7.1; F2 : 7.1--9.5; F3 : 9.5--2.4; F4: >12.4 kPa). The APRI and FIB-4 scores were calculated at baseline, EOT and 12 weeks after EOT. RESULTS One hundred and seventy-eight patients were examined throughout a follow-up of 16.3 months (IQR: 12.5-25). The median of liver stiffness decrease was 2.6 kPa (IQR: 0-6.3). A greater improvement was observed in F3-F4 compared with F1-F2, (6.4 vs. 0.91 kPa, P < 0.001; P = 0.001, respectively). A decline between baseline and EOT measures was observed in APRI and FIB-4 (P < 0.001). Sustained virological response (SVR12) achievement was the only predictor of fibrosis regression [OR:17.4 (95% CI: 1.8-164.6; P = 0.013)]. CONCLUSION Most patients experienced a significant reduction of liver stiffness and APRI and FIB-4 scores. This improvement was greater in those with advanced liver disease. SVR12 was the only predictor of fibrosis regression. The significance of this reduction is unclear and could reflect a decline in inflammation rather than true fibrosis regression.

Abstract
BACKGROUND Hepatitis B and C virus (HBV and HCV) are the two most common infections among human immunodeficiency virus (HIV)-infected patients. OBJECTIVE To identify the frequency of HIV subtypes and HCV genotypes in HIV-coinfected patients. METHODS A cross-sectional and retrospective study was carried out into two reference centers in Southern Brazil between January 1, 2002 and June 30, 2016. The Abbott Real Time HCV Genotype II system was used for routine diagnostics to determine the HCV genotype based on dual-target real-time PCR. Proviral HIV-1 RNA was extracted from serum samples and fragments of the pol gene were generated by PCR. The HIV-1 PT and RT gene sequences were submitted to Maximum Likelihood Phylogenetic analysis by collecting reference sequences from the HIV-1 group M subtype of the Los Alamos database. RESULTS During the study period, 3340 patients with HIV were diagnosed at both referral centers, of which 4.97% (166/3340) had HBV and/or HCV coinfection. Seroprevalence of HIV-HBV, HIV-HCV and HIV-HBV-HCV was 37.4%, 58.4%, and 4.2%, respectively. HIV-HCV-coinfected patients had a lower median nadir CD4+ T-cell count when compared to HIV-HBV-coinfected patients (P=0.01). Among those coinfected with HCV, HCV-1 (HCV-1) and HCV-3 (HCV-3) genotypes were the most prevalent, being detected in 73.8% and 21.4%, respectively. Among the HCV-1 coinfected patients, 79.3% and 20.1% had subtypes 1a and 1b, respectively. HIV subtype B was the most prevalent in HIV-coinfected patients. There was no significant difference regarding nadir CD4+ T-cell count and HIV viral load when compared to coinfected with HCV-1 with HCV-3, as well as those co-infected with HCV-1a with HCV-1b. CONCLUSION In the present study, a higher frequency of subtype B of HIV and HCV-1 were found in HIV-coinfected patients. Further larger-scale and long-term studies are needed to better understand the effect of HCV genotypes in HIV-infected patients.

Abstract
: Elevation of liver transaminases is common in patients infected with the HIV. Although this is usually an incidental finding during regular work-up, HIV-infected patients with transaminase elevations require additional visits for laboratory studies and clinical assessments, and often undergo interruptions and changes in antiretroviral therapy (ART). Alanine aminotransferase is present primarily in the liver, thus being a surrogate marker of hepatocellular injury. Aspartate aminotransferase is present in the liver and other organs, namely cardiac and skeletal muscle, kidney and brain. Serum levels of both liver transaminases predict liver-related mortality. Moreover, serum fibrosis biomarkers based on alanine aminotransferase and aspartate aminotransferase predict all-cause mortality. In a busy clinical setting, a diagnostic approach to elevated liver transaminases could be complicated given the frequency and nonspecificity of this finding. Indeed, HIV-infected individuals present multiple risk factors for liver damage and chronic elevation of transaminases, including coinfection with hepatitis B and C viruses, alcohol abuse, hepatotoxicity due to ART, HIV itself and frequent metabolic comorbidities leading to nonalcoholic fatty liver disease. This review provides an update on epidemiology of elevated liver transaminases, summarizes the main etiologic contributors and discusses the prognostic significance and a pragmatic approach to this frequent finding in the clinical practice of HIV medicine. With the aging of the HIV-infected population following the successful implementation of ART in Western countries, liver-related conditions are now a major comorbidity in this setting. As such, clinicians should be aware of the frequency, clinical significance and diagnostic approach to elevated liver transaminases.

Abstract
Lipodystrophy is a group of clinically heterogeneous, inherited or acquired, disorders characterized by complete or partial absence of subcutaneous adipose tissue that may occur simultaneously with the pathological, ectopic, accumulation of fat in other regions of the body, including the liver. Fatty liver adds significantly to hepatic and extra-hepatic morbidity in patients with lipodystrophy. Lipodystrophy is strongly associated with severe insulin resistance and related comorbidities, such as hyperglycemia, hyperlipidemia and nonalcoholic fatty liver disease (NAFLD), but other hepatic diseases may co-exist in some types of lipodystrophy, including autoimmune hepatitis in acquired lipodystrophies, or viral hepatitis in human immunodeficiency virus (HIV)-associated lipodystrophy. The aim of this review is to summarize evidence linking lipodystrophy with hepatic disease and to provide a special focus on potential therapeutic perspectives of leptin replacement therapy and adiponectin upregulation in lipodystrophy.

Abstract
Despite successful HIV suppression by antiretroviral treatment (ART), immune activation may persist in HIV patients, contributing to an impaired immunological reconstitution and disease progression. Information regarding Hepatitis C virus (HCV) coinfection as a factor that accounts for immune activation in HIV subjects remains unclear. Furthermore, most studies have been carried out considering HIV/HCV patients as a whole, without taking into account the presence or absence of liver damage. Therefore, it is unknown if HCV and/or its liver-related disease could act as two independent factors contributing to the immune activation. In this study, we investigated the presence of immune activation in a cohort of 50 HIV/HCV patients by measuring cytokine levels, CD4+ T-cell counts and CD4/CD8 ratios. Six patient groups were defined according to HIV viral load, HCV status, and liver disease to assess the impact of each of these factors on immune activation and reconstitution in HIV/HCV patients. Only subjects with controlled HIV infection and cleared HCV displayed immunological parameters within normal ranges. The mere presence of HCV contributes to immune activation leading to an inappropriate immunological reconstitution. This state exacerbates in the presence of HCV-associated liver disease. Our results suggest that ART is not enough to suppress immune activation in the context of HIV/HCV coinfection, since both HCV and its liver-related disease would contribute to the immune activation. Given that immune activation worsens immunological reconstitution and clinical status, these results support the priority of HCV treatment in HIV/HCV patients and suggest the monitoring of their liver status.

Abstract
The rates of both HIV and HCV are exploding among the People Who Inject Drugs (PWID) subpopulation in the People's Republic of Bangladesh. 5,586 HIV confirmed cases have been reported since the first case of HIV was identified in 1989, of which, 865 new cases (15.5%) have been reported in the year 2017 alone. Among the new cases, 330 (38.2%) were from PWID population. The HCV prevalence is also high in Dhaka, with 40% of the PWID with unknown HIV status and 60.7% co-infected with HIV. The predominant HIV-1 strains circulating in the population are subtype C (41.4%) followed by CRF07 BC (24.2%), CRF01 AE (9.1), A1 (6.6%), and B (2.5%). HCV subtypes 3a and 3b are the most prevalent circulating strains (88.5%) among PWID. Harm reduction interventions particularly Needle Syringe Program (NSP) for PWID have been operating in Bangladesh since 1998. Opioid Substitution Therapy (OST) commenced in 2010 but only covers 2.9% of the total estimated PWID population in the country. A preliminary assessment of the needle/syringe sharing networks of HIV positive PWID was made in order to determine the HIV status among needle/syringe sharing partners. From a network of 36 HIV positive PWID seeds, 96 needle/syringe sharing partners were identified, of which 10 were HIV positive. Characterization of the nature of transmission within PWID networks is required in order to develop clinical services aimed at this vulnerable subpopulation and to halt the epidemic.

Abstract
BACKGROUND Early identification of patients with chronic viral hepatitis coinfected with human immunodeficiency virus (HIV) is essential for optimal care. The objectives of this study were to estimate the prevalence of HIV coinfection among patients newly diagnosed with chronic viral hepatitis, HIV testing prevalence, and identify factors associated with coinfection. METHODS Patients with chronic viral hepatitis newly enrolled in The Danish Database for Hepatitis B and C between 2002 and 2015 were identified. The HIV coinfection prevalence was calculated, and risk factors associated with HIV coinfection were estimated by logistic regression. RESULTS In total, 8490 patients were included: 3091 had chronic hepatitis B (CHB), 5305 had chronic hepatitis C (CHC), and 94 had CHB and CHC. The prevalence of HIV coinfection was 4.4% (95% confidence interval [CI], 4.0-4.9) and was higher among CHC and CHB-CHC patients than CHB patients with a prevalence of 5.3% (95% CI, 4.7-5.9), 6.4% (95% CI, 2.4-13.4), and 2.9 (95% CI, 2.3-3.5), respectively (P < .0001). The HIV testing prevalence increased from 65% to 88% between 2002 and 2014 concurrently with a decrease in the HIV coinfection prevalence from 7.8% (95% CI, 5.5-10.7) to 1.6% (95% CI, 0.7-3.2). Age 35-50 years, male sex, and sexual route of viral hepatitis transmission were associated with HIV coinfection with odds ratios of 4.42 (95% CI, 1.40-13.94), 2.21 (95% CI, 1.74-2.81), and 8.81 (95% CI, 6.30-12.33), respectively. CONCLUSIONS The prevalence of HIV coinfection among patients with newly diagnosed chronic viral hepatitis decreased concurrently with an increase in HIV testing prevalence.

Abstract
BACKGROUND Chronic Hepatitis C virus (cHCV) is a major health issue worldwide. New effective direct-acting anti-viral (DAA) drugs such as the combination sofosbuvir/velpatasvir, represent an important turning point, given the high sustained virologic response (SVR) rates associated with their use. OBJECTIVES To estimate the cost and effects of two different treatment strategies based on sofosbuvir/velpatasvir. Strategy 1: treating all patients, including those in the early stages of fibrosis; Strategy 2: reserving treatments for patients at more advanced stages of disease (≥ F3). The analysis compares the incremental cost-effectiveness ratio (ICER) of Strategy 1 versus Strategy 2 in a cohort of HCV-infected patients and a cohort of hepatitis C virus (HCV)-human immunodeficiency virus (HIV) patients. METHODS A Markov model simulating the natural history of the disease was built considering a 60-year time horizon and two cohorts of 1000 patients aged ≥ 35 years. Disease morbidity was classified according to the METAVIR classification. The robustness of the model was tested using deterministic and probabilistic sensitivity analyses (PSA). RESULTS In both cohorts, Strategy 1 results in higher resource consumption and a greater number of quality-adjusted life-years (QALYs) compared with Strategy 2. The ICERs for the cohort of HCV patients and the cohort of co-infected HCV/HIV patients ranged between €15,555-74,804/QALY and €10,708-55,138/QALY, respectively, depending on the assumed cost of the treatment. In the PSA, the ICER distribution remained below the threshold of €30,000/QALY in 96 and 97% of the scenarios in the cohorts of HCV and HCV/HIV patients, respectively. CONCLUSIONS Extending the treatment of HCV to patients at an early stage of HCV infection is estimated to be cost effective from the perspective of the Italian Healthcare System.

Abstract
Background Heavy alcohol use can lead to progressive liver damage, especially in individuals with chronic hepatitis C (HCV); however, the impact of nonheavy use is not clear. We studied long-term effects of modest alcohol use on fibrosis progression in a large cohort of women coinfected with human immunodeficiency virus (HIV)/HCV. Methods Alcohol intake was ascertained every 6 months and use categorized as abstinent, light (1-3 drinks/week), moderate (4-7 drinks/week), heavy (>7 drinks/week), and very heavy (>14 drinks/week). Fibrosis progression was defined as the change in Fibrosis-4 Index for Liver Fibrosis (FIB-4) units per year using random-intercept, random-slope mixed modeling. Results Among 686 HIV/HCV-coinfected women, 46.0% reported no alcohol use; 26.8% reported light use, 7.1% moderate use, and 19.7% heavy use (6.7% had 8-14 drinks/week and 13.0% had >14 drinks/week) at cohort entry. Median FIB-4 at entry was similar between groups. On multivariable analysis, compared to abstainers, light and moderate alcohol use was not associated with fibrosis progression (0.004 [95% confidence interval {CI}, -.11 to .12] and 0.006 [95% CI, -.18 to .19] FIB-4 units/year, respectively). Very heavy drinking (>14 drinks/week) showed significant fibrosis acceleration (0.25 [95% CI, .01-.49] FIB-4 units/year) compared to abstaining, whereas drinking 8-14 drinks per week showed minimal acceleration of fibrosis progression (0.04 [95% CI, -.19 to .28] FIB-4 units/year). Conclusions Light/moderate alcohol use was not substantially associated with accelerated fibrosis progression, whereas drinking >14 drinks per week showed increased rates of fibrosis progression. Women with HIV/HCV infection should be counseled against heavy alcohol consumption, but complete abstinence may not be required to prevent accelerated liver fibrosis progression.

Abstract
A DNA methylation (DNAm) signature (the "Horvath clock") has been proposed as a measure of human chronological and biological age. We determined peripheral blood DNAm in patients with nonalcoholic steatohepatitis (NASH) and assessed whether accelerated aging occurs in these patients. DNAm signatures were obtained in patients with biopsy-proven NASH and stage 2-3 fibrosis. The DNAm profile from one test and two validation cohorts served as controls. Age acceleration was calculated as the difference between DNAm age and the predicted age based on the linear model derived from controls. Hepatic collagen content was assessed by quantitative morphometry. The Horvath clock accurately predicts the chronological age of the entire cohort. Age acceleration was observed among NASH subjects compared with control data sets and our test controls. Age acceleration in NASH subjects did not differ by fibrosis stage but correlated with hepatic collagen content. A set of 152 differentially methylated CpG islands between NASH subjects and controls identified gene set enrichment for transcription factors and developmental pathways. Patients with NASH exhibit epigenetic age acceleration that correlates with hepatic collagen content.

Abstract
BACKGROUND In patients with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) co-infection, HIV can modulate HCV replication and immune response as well as accelerate liver fibrosis. The role of miRNA in HIV/HCV co-infection is not fully elucidated. The aim of this study was to examine the differential expression of miRNAs in the liver. MATERIAL AND METHODS Thirteen patients who had undergone a liver transplant (7 HCV-infected and 6 HIV/HCV-co-infected patients) were examined using a miRNA array containing 1347 human miRNAs. To confirm the microarray results, data for 20 patients (10 HCV-infected and 10 HIV/HCV-co-infected) were validated using real-time polymerase chain reaction probing for miR101b, miR149, and miR200c. This miRNA was selected based on microarray results and its biological significance in liver fibrosis. RESULTS Microarray analysis revealed 22 miRNAs that were differentially expressed in the HIV/HCV-co-infected group compared to the HCV-infected group (p<0.05). The expression of miR-101b and miR149 was significantly decreased in the HIV/HCV-co-infected group compared to that in the HCV-infected group (miR101b, 0.103±0.09 vs. 0.0157±0.0093, p=0.007; miR149, 0.152±0.159 vs. 0.0192±0.015, p=0.025). CONCLUSIONS HIV/HCV co-infection may promote liver fibrosis by modulating miRNA expression.

Abstract
Background Hepatitis B (HBV) and C (HCV) are important causes of morbidity and mortality in people living with human immunodeficiency virus (HIV). The burden of these co-infections in sub-Saharan Africa is still unclear. We estimated the prevalence of the hepatitis B surface antigen (HBsAg) and hepatitis C antibody (HCVAb) among HIV-infected individuals in Rwanda and identified factors associated with infection. Methods Between January 2016 and June 2016, we performed systematic screening for HBsAg and HCVAb among HIV-positive individuals enrolled at public and private HIV facilities across Rwanda. Results were analyzed to determine marker prevalence and variability by demographic factors. Results Overall, among 117,258 individuals tested, the prevalence of HBsAg and HCVAb was 4.3% (95% confidence interval [CI] (4.2–4.4) and 4.6% (95% CI 4.5–4.7) respectively; 182 (0.2%) HIV+ individuals were co-infected with HBsAg and HCVAb. Prevalence was higher in males (HBsAg, 5.4% [5.1–5.6] vs. 3.7% [3.5–3.8]; HCVAb, 5.0% [4.8–5.2] vs. 4.4% [4.3–4.6]) and increased with age; HCVAb prevalence was significantly higher in people aged ≥65 years (17.8% [16.4–19.2]). Prevalence varied geographically. Conclusion HBV and HCV co-infections are common among HIV-infected individuals in Rwanda. It is important that viral hepatitis prevention and treatment activities are scaled-up to control further transmission and reduce the burden in this population. Particular efforts should be made to conduct targeted screening of males and the older population. Further assessment is required to determine rates of HBV and HCV chronicity among HIV-infected individuals and identify effective strategies to link individuals to care and treatment.

Abstract
BACKGROUND While highly active anti-retroviral therapy (HAART) has improved survival of HIV-infected patients, there is increasing liver disease and progressive Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) related liver disease. AIMS To study the liver function tests (LFT) and HBV and HCV co-infection in HIV-infected patients. MATERIAL AND METHODS All HIV-positive patients presenting to a tertiary level hospital from April 2009 to April 2011 were evaluated. Baseline LFT, CD4/CD8 counts, ultrasound abdomen, HBsAg, IgG anti-HBc, HBVDNA, Anti-HCV and HCVRNA were done in all patients. LFT was repeated monthly or more frequently with anti-tubercular therapy (ATT)/HAART. RESULTS Abnormal LFT were seen in 143/320 (44.6%) HIV-infected patients (n = 320; M-282, F-38; mean age-35.4 ± 7.3 years). Baseline LFT was abnormal in 48 (15%) [hepatotropic viruses-19, alcohol-24, NAFLD-1, disseminated TB-1, idiopathic-03). Subsequent LFT derangement developed in 95/272 (34.9%). In the majority, the LFT abnormality was mild (119/143-83.2%) and multi-factorial [HAART 132 (76.4%), alcohol 69 (48.2%), ATT 31 (21.7%), HBV 16 (11.2%), HCV 15 (10.4%)]. Using multivariate analysis, abnormal LFT were associated with HAART (OR, 5.92; 95%CI, 2.83-12.37), ATT (OR, 2.06; 95%CI, 1.06-3.99) or HCV infection (OR, 2.54; 95%CI, 1.03-6.26). Significant hepatotoxicity requiring drug modification was seen in only 7 cases. HBV, HCV and HBV + HCV co-infection were seen in 37 (11.6%), 28 (8.8%) and 2 (0.6%) respectively. Occult co-infections were rare [HBV-1 (0.3%); HCV-3 (0.9%)]. CONCLUSION While LFT abnormalities in HIV are common, they are usually mild and multifactorial. HBV and HCV co-infections were seen in 11.6% and 8.8%, respectively. Occult HBV and HCV infections were rare.

Abstract
BACKGROUND Treatment of HCV/HIV coinfection is now largely based on utilization of direct acting agents. Pretreatment viral resistant-associated variants (RAVs) and host liver condition may affect the sustained virological response. In this study, we explored relative prevalence of protease resistance-associated mutations, the evolution of those RAVs after 12 weeks of pegylated interferon alfa exposure, and the role hepatic fibrosis might have on RAV display. METHODS Thirty nonresponder HCV/HIV-coinfected subjects were evaluated before and after 12 weeks of PegIFN treatment. Ultra-deep sequence analysis of NS3 RAVs was performed. Hepatic fibrosis was determined by sensitive computer-assisted histomorphometry determination. RESULTS At baseline, protease inhibitor RAVs were present in 73.3% of patients and expanded to 83.3% of patients after 12 weeks of PegIFN exposure. Q80K showed the highest prevalence before and after treatment at 46.7% and 56.7%, respectively. The presence of Q80K is positively correlated with percent collagen content of the liver tissue. CONCLUSIONS Key RAVs for HCV protease inhibitors are present in a major portion of the HCV/HIV-coinfected population before therapy. Some variants get selected after exposure. Correlation of Q80K with collagen content of the liver suggests that compartmentalization within the liver may contribute to persistence of mutations less fit than wildtype.

Abstract
OBJECTIVE Liver disease is a frequent cause of morbidity and mortality in HIV infection. We examined the relationship of cocaine use, liver disease progression and mortality in an HIV-infected cohort. METHODS Consent was obtained from 487 HIV+ participants, a subset of the Miami Adult Studies on HIV (MASH) cohort. Participants were eligible if they were followed for at least two years, completed questionnaires on demographics and illicit drug use and had complete metabolic panels, CD4 cell counts and HIV-viral loads. FIB-4 was calculated and cut-off points were used for staging liver fibrosis. Death certificates were obtained. RESULTS Participants were 65% men, 69% Black and 81% were on ART at recruitment. Cocaine was used by 32% of participants and 29% were HIV/HCV co-infected. Mean age was 46.9 ± 7.7 years, mean CD4 cell count was 501.9 ± 346.7 cells/μL and mean viral load was 2.75 ± 1.3 log10 copies/mL at baseline. During the follow-up, 27 patients died, with a mortality rate of 28.2/1000 person-year. Cocaine was used by 48% of those who died (specific mortality rate was 13/1000 person-year). Those who died were more likely to use cocaine (HR=3.8, P=0.006) and have more advanced liver fibrosis (HR=1.34, P<0.0001), adjusting for age, gender, CD4 cell count and HIV-viral load at baseline and over time. Among the HIV mono-infected participants, cocaine users were 5 times more likely to die (OR=5.09, P=0.006) than participants who did not use cocaine. CONCLUSION Cocaine use and liver fibrosis are strong and independent predictors of mortality in HIV infected and HIV/HCV co-infected adults. Effective interventions to reduce cocaine use among people living with HIV (PHLW) are needed.

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
INTRODUCTION Chronic HIV/hepatitis C virus (HCV) coinfection carries increased risk of cirrhosis, hepatocellular carcinoma, and death. Due to anti-inflammatory properties, 3-hydroxy-3methylglutaryl coenzyme A (HMG-CoA) inhibitors (statins) may be useful adjunctive therapy to reduce liver disease progression. METHODS Clinical information was extracted from the Veterans Affairs HIV and HCV Clinical Case Registries (1999-2010). HIV-related variables included combination antiretroviral therapy era of diagnosis, CD4 cell count, and percentage time with undetectable HIV viral load. Metabolic variables included diabetes, low high-density lipoprotein (HDL), and hypertension. Statin use was measured as percentage time with active prescription (time-updated throughout the follow-up period). Cox proportional hazards analysis was used to determine risk factors for cirrhosis (International Classification of Diseases-9 or aminotransferase-to-platelet ratio index >2) overall and in groups stratified by alanine aminotransferase (ALT) level above and below 40 IU/l. RESULTS The cohort included 5985 HIV/HCV coinfected veterans. The majority was black race, and the mean age at index date was 45 years. Statin use was significantly protective of cirrhosis for patients with ALT 40 IU/l or less; for every 30% increase in time on statin, there was a 32% decreased risk of developing cirrhosis (hazard ratio 0.68, 95% confidence interval 0.47-0.98). Diabetes and low HDL were significantly associated with cirrhosis in patients with ALT greater than 40 IU/l (hazard ratio 1.15, P < 0.04 and hazard ratio 1.3, P < 0.0001). CONCLUSION Statin drug use is beneficial in mitigating the risk of liver disease progression for HIV/HCV coinfected patients without advanced liver disease. Low HDL and diabetes in coinfected patients with abnormal ALT have greater risk of cirrhosis development.

Abstract
Hepatitis C virus infection is a hot topic for both effective treatment and elevated cost. This case series describes the cost saving for the healthcare system of any nation of treating HCV in many situations, including that of overt cirrhosis. Case#1 is of a HCV/HIV infected cirrhotic patient with MELD score of 17, Child Pugh score B, recurrent esophageal bleeds ceased after successful treatment with sofosbuvir and simepravir. Case#2 is a patient also co-infected with HCV/HIV MELD score of 18, Child Pugh score B, with grade 3 esophageal varices and frequent bleed with significant anemia. With a regimen of sofosbuvir and ribavirin the patient had no more hospitalization for GI bleed. HCV infection is still underdiagnosed, picking up on it early, sufficient treatment and follow up may reduce healthcare costs in the long run by significant measures.

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
Generalized CD8+ T-cell impairment in chronic hepatitis C virus (HCV) infection and the contribution of liver-infiltrating CD8+ T-cells to the immunopathogenesis of this infection remain poorly understood. It is hypothesized that this impairment is partially due to reduced CD8+ T-cell activity in response to cytokines such as IL-7, particularly within the liver. To investigate this, the phenotype and cytokine responsiveness of blood- and liver-derived CD8+ T-cells from healthy controls and individuals with HCV infection were compared. In blood, IL-7 receptor α (CD127) expression on bulk CD8+ T-cells in HCV infection was no different than controls yet was lower on central memory T-cells, and there were fewer naïve cells. IL-7-induced signalling through phosphorylated STAT5 was lower in HCV infection than in controls, and differed between CD8+ T-cell subsets. Production of Bcl-2 following IL-7 stimulation was also lower in HCV infection and inversely related to the degree of liver fibrosis. In liver-derived CD8+ T-cells, STAT5 activation could not be increased with cytokine stimulation and basal Bcl-2 levels of liver-derived CD8+ T-cells were lower than blood-derived counterparts in HCV infection. Therefore, generalized CD8+ T-cell impairment in HCV infection is characterized, in part, by impaired IL-7-mediated signalling and survival, independent of CD127 expression. This impairment is more pronounced in the liver and may be associated with an increased potential for apoptosis. This generalized CD8+ T-cell impairment represents an important immune dysfunction in chronic HCV infection that may alter patient health.

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 As the field of antiviral therapy for chronic HCV infection is rapidly evolving, this study aimed to assess the epidemiological changes in patient and disease characteristics among individuals with chronic HCV infection. METHODS This study included all consecutive patients with chronic HCV monoinfection who were referred between 1990 and 2013 to the Erasmus MC University Medical Center Rotterdam, a large tertiary centre in the Netherlands. To identify trends over time, the study population was divided into six equal eras based on date of first visit to the outpatient clinic. RESULTS A total of 1,779 patients were diagnosed with chronic HCV infection. Mean age increased over time from 43.6 (sd 13.8) years to 51.7 (sd 11.2) years (P<0.001). The number of patients who were referred with cirrhosis increased over time, from 31 (25%) patients in Era 1 to 118 (42%) patients in Era 6 (P<0.001), respectively. More patients were referred with HCV genotype 1a and 3 in the last era, with 27 (48.2%) and 15 (14.0%) patients in Era 1 and 58 (54.2%) and 60 (21.8%) patients in Era 6 (P<0.001 both), respectively. The vast majority of patients (69.5%) were born between 1950 to 1975, with 62.5% of the patients being born between 1945 and 1965. CONCLUSIONS The HCV-infected population is ageing and is more often referred with severe liver disease. This study stresses the importance of urgently implementing national HCV screening programmes in order to be able to decrease the future burden of chronic HCV infection in the Netherlands.

[PMID: 26298331 PMCID: PMC4577462 DOI: 10.1016/j.drugpo.2015.07.004] [Citation(s) in RCA: 78] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2015] [Revised: 05/27/2015] [Accepted: 07/07/2015] [Indexed: 12/12/2022]
Abstract
BACKGROUND Understanding HCV disease progression rates among people who inject drugs (PWID) is important to setting policy to expand access to detection, diagnosis and treatment, and in forecasting the burden of disease. In this paper we synthesize existing data on the natural history of HCV among PWID, including fibrosis progression rates (FPR) and the incidence of compensated cirrhosis (CC), decompensated cirrhosis (DC), and hepatocellular carcinoma (HCC). METHODS We conducted electronic and manual searches for published and unpublished literature. Reports were eligible if they (i) included participants who were chronically infected with HCV and reported current or previous injection drug use; (ii) presented original data on disease progression in a study sample comprised of at least 90% PWID; (iii) published between January 1, 1990, and December 31, 2013; and (iv) included data from upper-middle- or high-income countries. Quality ratings were assigned using an adaptation of the Quality In Prognosis Studies (QUIPS) tool. We estimated pooled FPRs using the stage-constant and stage-specific methods, and pooled incidence rates of CC, DC, and HCC. RESULTS Twenty-one reports met the study inclusion criteria. Based on random-effect models, the pooled stage-constant FPR was 0.117 METAVIR units per year (95% CI, 0.099-0.135), and the stage-specific FPRs were F0→F1, 0.128 (95% CI 0.080, 0.176); F1→F2, 0.059 (95% CI 0.035, 0.082); F2→F3, 0.078 (95% CI 0.056, 0.100); and F3→F4, 0.116 (95% CI 0.070, 0.161). The pooled incidence rates of CC, DC, and HCC were 6.6 (95% CI 4.8, 8.4), 1.1 (95% CI 0.8, 1.4), and 0.3 (95% CI -0.1, 0.6) events per 1000 person-years, respectively. Following the stage-constant estimate, average time to cirrhosis is 34 years post-infection, and time to METAVIR stage F3 is 26 years; using the stage-specific estimates, time to cirrhosis is 46 years and time to F3 is 38 years. CONCLUSION Left untreated, PWID with chronic HCV infection will develop liver sequelae (including HCC) in mid- to late-adulthood. Delaying treatment with the new drug regimens until advanced fibrosis develops prolongs the period of infectiousness to perhaps thirty years. Scaling up of effective HCV prevention and early engagement in care and treatment will facilitate the elimination HCV as a source of serious disease in PWID.

Abstract
The Asia-Pacific region bears a high burden of hepatitis C virus (HCV) infections and the largest number of global deaths. Populations most at risk of infection and disease progression include people who inject drugs and those living with HIV. HCV treatment options have rapidly expanded in the past few years through the development of direct-acting antiviral (DAA) medicines, which can cure HCV in over 95% of cases, but are prohibitively expensive. While price is the major barrier to treatment access, voluntary licensing has resulted in limited availability of one DAA (sofosbuvir) through generic manufacturers in India. Regulatory barriers, such as the need for domestic clinical trials, cause further delays in local medicines approvals and access. Intensive advocacy by civil society in combination with mobilisation of global resources for HIV treatment were critical to achieving price reductions in HIV medicines in the early 2000s. While the current global economic situation is less conducive to substantial funding support for HCV treatment, community advocates are building awareness of the growing opportunities for HCV cure. Key immediate steps include the inclusion of DAAs in domestic essential medicines lists, as the World Health Organization has already done for globally, and fast-tracking domestic drug approvals to facilitate government-level price negotiations with originator and generic pharmaceutical companies. Urgent action by a broad range of stakeholders is needed to facilitate access to HCV treatment in order to ensure that the millions of people living with hepatitis C in the Asia-Pacific will not miss out on these life-saving treatments.

Abstract
Several studies have demonstrated that HIV/hepatitis C virus (HCV)-coinfected patients experience more rapid fibrosis progression. In this study, to estimate the annual rate of direct liver fibrosis progression, we used analyses of paired biopsy samples from HIV/HCV-coinfected patients without prior treatment of hepatitis and assessed the possible association of fibrosis progression with certain clinical variables. We evaluated 30 HIV/HCV-coinfected patients, with no history of prior treatment of hepatitis C, who underwent paired liver biopsies. All patients were under antiretroviral therapy at first and second biopsies. The average annual progression rate was 0.13 fibrosis unit/year, with 36.7% of patients defined as progressors. Liver fibrosis progression was associated with alanine aminotransferase (ALT; P < .001) and aspartate aminotransferase (AST; P < .0340) levels over 3 times the upper limit of normal present at first biopsy. Elevated ALT and AST levels appear to be associated with more accelerated liver fibrosis progression among HIV/HCV-coinfected patients.

Abstract
Human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infection is characterized by higher serum HCV RNA loads compared with HCV mono-infection. However, the relationship between HIV and HCV replication remains to be clarified. HIV Vpr has been shown to play an essential role in HIV replication. In this study, we aimed to explore the role of Vpr in HCV replication and pathogenesis. We therefore used the genotype 2a full-length HCV strain JFH1 infection system and the genotype 1b full-length HCV replicon OR6 cell line to analyse the effects of Vpr on HCV replication. We found that Vpr promoted HCV 5′ UTR activity, HCV RNA replication and HCV protein expression in two HCV infection cell models. Additionally, lymphocyte-produced Vpr significantly induced HCV 5′ UTR activity and HCV replication in hepatocytes. We also found that Vpr upregulated the expression of miR-122 by stimulating its promoter activity. Furthermore, an miR-122 inhibitor suppressed the Vpr-mediated enhancement of both HCV 5′ UTR activity and HCV replication. In summary, our results revealed that the Vpr-upregulated expression of miR-122 is closely related to the stimulation of HCV 5′ UTR activity and HCV replication by Vpr, providing new evidence for how HIV interacts with HCV during HIV/HCV co-infection.

Abstract
Background. Human immunodeficiency virus (HIV) coinfection accelerates liver disease progression in individuals with chronic hepatitis C. We evaluated the associations of CD4, HIV RNA, and antiretroviral therapy (ART)-induced CD4 recovery with liver diagnoses in a prospective cohort of injecting drug users (IDUs). Methods. We evaluated 383 coinfected IDUs in the Boston area, prospectively observed for a median of 1.8 years. Liver disease progression included the first occurrence of hepatocellular carcinoma, variceal bleeding, ascites, encephalopathy, or death due to hepatic failure. Multivariable-adjusted extended Cox models were specified to estimate hazard ratios (HRs) for comparisons of CD4, change in CD4 (from nadir), and HIV RNA with respect to liver disease progression events. Results. Twenty-four persons experienced a liver disease progression event over 1155 person-years (2.1 per 100 person-years), including 20 deaths attributed to end-stage liver disease (1.7 per 100 person-years). CD4 at baseline and over follow-up strongly predicted liver disease progression (baseline CD4 <200 vs ≥200: HR = 5.23, 95% confidence interval [CI], 2.30-11.92; time-updated CD4 <200 vs ≥200: HR = 11.79, 95% CI, 4.47-31.07). Nadir CD4 was also a strong indicator (<100 vs ≥100: HR = 3.52, 95% CI, 1.54-8.06). A lack of CD4 recovery (failure to increase 100 cells over nadir) among ART initiators was associated with increased risk (HR = 7.69; 95% CI, 2.60-22.69). Human immunodeficiency virus RNA was not significantly associated with liver disease progression. Conclusions. Impaired immune function was highly predictive of liver disease progression in this cohort of IDUs, and a lack of CD4 recovery on ART was associated with increased risk of progression to HCV-associated liver disease.

Abstract
OBJECTIVES Serum hepatitis C virus (HCV) core antigen (HCVcAg) concentrations correlate with HCV RNA levels in HCV monoinfected patients. Data in HCV/HIV coinfected patients are still limited. We aim to compare the use of HCVcAg measurement with respect to HIV status, HCV genotypes, interferon-lambda-4 (IFNL4) polymorphism and clinical parameters. METHODS We analyzed an untreated cohort of 104 patients with HCV monoinfection and 85 patients with HCV/HIV coinfection. Serum HCVcAg was measured by a commercial chemiluminescent microparticle immunoassay. The presence of IFNL4 polymorphism ss469415590 was identified by real-time PCR. RESULTS log10 HCVcAg levels were significantly correlated with corresponding log10 HCV RNA levels (r = 0.889, p < 0.001), but not with ALT levels and liver stiffness. The correlation between HCV RNA and HCVcAg was particularly high in coinfected patients and those with high viremia. Mean log10 HCVcAg concentration was significantly higher in coinfected patients than in monoinfected patients. Patients harboring the TT/TT genotype of ss469415590 had significantly higher levels of log10 HCVcAg than those with the non-TT/TT genotype. HCVcAg levels were similar across HCV genotypes. CONCLUSIONS HCVcAg concentrations had an excellent correlation with HCV RNA levels, particularly in HCV/HIV-coinfected individuals and might be associated with IFNL4 polymorphism. HCVcAg testing could be used as an alternative to HCV RNA assays in resource-limited settings.

Abstract
PURPOSE A cross-sectional study was performed during 2004 at a large HIV clinic in Spain to identify HIV-HCV coinfected individuals who might be candidates for HCV therapy. METHOD Plasma HCV RNA levels were measured in 405 anti-HCV antibody positive patients. Spontaneous HCV clearance had occurred in 11.4%. Overall, 165 (40.1%) of HCV-HIV coinfected patients had already been exposed to interferon (IFN)-based therapies. Excluding those currently on treatment, the majority of them had either failed (64/142; 45.1%) or not completed therapy (25/142; 17.6%). Other 103 (25.4%) chronic HCV carriers refused treatment or were not considered as appropriate candidates, most often due to low CD4 counts or severe neuropsychiatric conditions. Treatment was deemed feasible and planned in the near future in 91 (22.5%) patients. Unfavorable HCV genotypes (1 and 4) were significantly more frequent in this group of individuals ready for HCV treatment compared to those who had cleared HCV in the past following IFN-based therapies. RESULTS Spontaneous clearance of the HCV infection was low in HIV-coinfected patients. One third of our HIV-HCV coinfected population had already been exposed to HCV therapy, but only a minority had achieved sustained HCV clearance. Half of patients with active HCV replication never exposed to IFN were not considered as appropriate candidates for HCV therapy. CONCLUSION More flexible criteria would considerably increase the number of patients to be treated with IFN-based therapy. The majority of patients ready to initiate HCV therapy have a poor therapeutic profile.

Abstract
The role of host response-related factors in the fast progression of liver disease in individuals co-infected with HIV and HCV viruses remains poorly understood. This study compared patterns of cytokines, caspase-1 activation, endotoxin exposure in plasma as well as interferon signaling in peripheral blood mononuclear cells from HIV/HCV co-infected (HIV(+)/HCV(+)), HCV mono-infected (HIV(-)/HCV(+)), HIV mono-infected (HIV(+)/HCV(-)) female patients and HIV- and HCV-uninfected women (HIV(-)/HCV(-)) who had enrolled in the Women's Interagency HIV Study (WIHS). HIV(+)/HCV(+) women had higher plasma levels of pro-inflammatory cytokines as well as caspase-1 compared with other groups. Both HIV(+)/HCV(+) and HIV(+)/HCV(-) women had significantly higher sCD14 levels compared with other groups. Peripheral blood mononuclear cells from HCV mono-infected patients had reduced levels of phosphorylation of STAT1 compared with other groups as well as lower basal levels of expression of the IFN-stimulated genes, OAS1, ISG15, and USP18 (UBP43). Basal expression of USP18, a functional antagonist of ISG15, as well as USP18/ISG15 ratios were increased in the HIV(+)/HCV(+) group compared with HIV(-)/HCV(+) and HIV(+)/HCV(-) groups. A more pronounced systemic inflammatory profile as well as increased expression ratios of USP18 to ISG15 may contribute to the more rapid progression of liver disease in HIV(+)/HCV(+) individuals.

Abstract
Monitoring of liver fibrosis (LF) is an essential tool for preventing liver-related complications in HIV/HCV co-infected patients. In this study, we compared LF progression by transient elastometry (TE) in 50 HIV/HCV co-infected and 115 HCV mono-infected patients followed in our institution between June 2006 and December 2011. Patients naive to interferon therapy and with at least two measurements of liver stiffness by TE were included. In all, 76% of HIV/HCV co-infected and 75% of HCV mono-infected patients remained in the same stage of LF over time. Conversely, 19% and 15% of HIV/HCV co-infected and HCV mono-infected subjects, respectively, had progression to advanced LF (≥ F3). Our study found a similar proportion of HIV/HCV co-infected and HCV mono-infected patients that developed an advanced LF during the follow-up time considered. Alcohol abuse was the only factor significantly associated with the progression as evidenced by multiple quantile regression analysis.

Abstract
BACKGROUND AND AIM Vitamin D insufficiency plays an important role in liver fibrosis in hepatitis C virus (HCV)-infected patients. We assessed liver fibrosis by transient elastography and 25 hydroxy vitamin D [25(OH)D] status in HCV-infected patients, with (HIV/HCV) or without HIV co-infection (HCV) from Thailand. METHODS Fibrosis stage was defined as mild (< 7.1 kPa); moderate (7.2-9.4 kPa); severe (9.5-14 kPa), and cirrhosis (> 14 kPa). Hypovitaminosis D was defined as 25(OH)D < 30 ng/mL. Logistic regression analyses were used to assess predictors for significant fibrosis. Serum 25(OH) D levels, HCV genotypes (GT), interleukin-28B (IL28B) and HCV-RNA were assessed. RESULTS A total of 331 HCV and 130 HIV/HCV patients were enrolled (70% male, 35% people who inject drugs [PWIDs]). HCV GT distribution was as follows: GT3 47%, GT1 34%, GT6 17%. IL-28B CC genotype (rs12979860) were found in 88% of HIV/HCV and 85% of HCV. In HCV, liver fibrosis was mild in 56.5%; moderate in 18.4%; severe in 12.4%; and cirrhosis in 12.7%. In HIV/HCV, these figures were 30.6%, 27.8%, 17.6%, and 24.1%, respectively. Patients with significant fibrosis were more often male, older, with HIV infection, hypovitaminosis D, and less likely to be infected with GT6. Factors associated with significant fibrosis by multivariate analysis were HIV infection (adjusted odd ratio [95% confidential interval]: 2.67, 1.20-5.93), P = 0.016, Fib-4 score > 1.45 (6.30, 2.70-14.74), P < 0.001, and hypovitaminosis D (2.48, 1.09-5.67), P = 0.031. GT 6 was less likely to have advanced liver fibrosis (0.17, 0.05-0.65), P = 0.01. CONCLUSIONS HIV infection, Fib-4 score > 1.45, and hypovitaminosis D are strong and independent predictors for the presence of advanced fibrosis in our HCV-infected patients. These data highlight the urgent need of HCV treatment and vitamin D supplement in resource-limited settings.

Evaluating Liver Fibrosis by Transient Elastometry in Patients With HIV-HCV Coinfection and Monoinfection. HEPATITIS MONTHLY 2014; 14:e15426. [PMID: 25337140 PMCID: PMC4199183 DOI: 10.5812/hepatmon.15426] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/14/2013] [Revised: 12/23/2013] [Accepted: 02/14/2014] [Indexed: 12/11/2022]
Abstract
BACKGROUND Due to the high efficacy of combination antiretroviral therapy (cART), the number of patients living with HIV is increasing. Chronic HCV infection has become a leading cause of non-AIDS related morbidity and mortality in patients with HIV infection. OBJECTIVES The aim of this cross-sectional study was to identify factors associated with liver fibrosis (LF) in patients with HIV monoinfection and HIV-HCV coinfection. PATIENTS AND METHODS We analyzed LF by transient elastometry ([TE], Fibroscan) in three groups of patients (HIV, HIV-HCV and HCV) followed at the Infectious Diseases Department of University of Ancona, Italy, between October 2009 and November 2012. RESULTS In total, 354 adults including 98 HIV, 70 HIV-HCV and 186 HCV patients were studied. HIV-HCV patients had a longer duration of HIV (P < 0.006) and HCV (P < 0.001) infections. Additionally, they were receiving cART therapy for a longer period (P < 0.001); they had higher prevalence of lipodystrophy (P < 0.001) and higher HCV load (P = 0.004). LF was significantly more pronounced in HCV and HIV-HCV compared to HIV patients (P < 0.001). A total of 13.3%, 39.2% and 51.4% of HIV, HCV and HIV-HCV, respectively, showed a LF ≥ F2. Additionally, a severe LF (F = 4) was significantly more frequent among HIV-HCV compared to other groups. A longer exposure to didanosine, stavudine, lopinavir/ritonavir and fosamprenavir resulted in increased LF by univariate analysis (P ranging from < 0.001 to 0.007). By logistic regression analysis, the only variables significantly associated with increased LF were HCV coinfection, older age, and high AST values (P ranging from < 0.001 to 0.036). CONCLUSIONS HCV coinfection, older age and AST were associated with LF in patients with HIV infection.

Abstract
The management of co-infection with HIV and hepatitis C virus (HCV) is complicated by viral and drug-drug interactions, treatment-related side effects, and the poor response to therapy of certain HCV genotypes. Current or past drug use may also have a negative impact. HEPAVIH (ANRS CO13) is an ongoing French cohort study of co-infected individuals which combines medical and socio-behavioral follow-up. This cohort study aims at analyzing the course of HCV infection and access to HCV treatment in HIV-HCV co-infected patients, using both clinical and patient-reported outcomes. This article documents the main lessons learned to date from the HEPAVIH data and published literature, while describing research prospects and needs requiring further investigation in the field of patient-reported outcomes.

Abstract
Viral diversity is an important predictor of hepatitis C virus (HCV) treatment response and may influence viral pathogenesis. HIV influences HCV variability in the plasma; however, limited data on viral variability are available from distinct tissue/cell compartments in patients co-infected with HIV and HCV. Thus, this exploratory study evaluated diversity of the hypervariable region 1 (HVR1) of HCV in the plasma and liver for 14 patients co-infected with HIV and HCV. Median intra-patient genetic distances and entropy values were similar in the plasma and liver compartments. Positive immune selection pressure was observed in the plasma for five individuals and in the liver for three individuals. Statistical evidence supporting viral compartmentalization was found in five individuals. Linear regression identified ALT (P = 0.0104) and AST (P = 0.0130) as predictors of viral compartmentalization. A total of 12 signature amino acids that distinguish liver from plasma E1/HVR1 were identified. One signature amino acid was shared by at least two individuals. These findings suggest that HCV compartmentalization is relatively common among patients co-infected with HIV and HCV. These data also imply that evaluating viral diversity, including drug resistance patterns, in the serum/plasma only may not adequately represent viruses replicating with in the liver and, thus, deserves careful consideration in future studies.

IRANIAN RED CRESCENT MEDICAL JOURNAL 2014; 16:e13484. [PMID: 24719731 PMCID: PMC3965864 DOI: 10.5812/ircmj.13484] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/09/2013] [Revised: 09/06/2013] [Accepted: 10/07/2013] [Indexed: 11/25/2022]
Abstract
Background: Chronic infection with hepatitis C virus (HCV) is increasingly recognized as a major global health problem. Illicit injection drug use is an important risk factor for the rising hepatitis C virus (HCV) prevalence in IR Iran. Objectives: The objective of this study was to determine the long-term effectiveness (total quality adjusted life years (QALYs) gained) of methadone maintenance treatment (MMT program) in prevention of HCV infection among injecting drug users (IDUs). Materials and Methods: A number of Markov models were developed to model morbidity and mortality among IDUs. The input data used in modeling were collected by a self-reported method from 259 IDUs before registration and one year after MMT and also from previous studies. One way and probabilistic sensitivity analyses were done to show the effects of uncertainty in parameters on number of life years and QALYs saved. The expected consequences were estimated using a life-time time horizon for the two strategies including implementation and not implementation of the MMT program. Results: Our model estimated that total number of discounted life years lived per IDU with and without the MMT program would be 5.15 (5.05 - 5.25) and 4.63 (4.42 - 4.81), respectively. The model also estimated that total number of discounted QALYs lived per IDU with and without the MMT program would be 4.11 (3.86 - 4.41) and 2.45 (2.17 - 2.84). Simulation results indicated that all differences in life years and QALYs lived between the two strategies were statistically significant (p < 0.001). Based on our model, total discounted life years and QALYs saved in a cohort of 1000 IDUs were 1790 (1520 - 2090) and 1590 (1090- 2090), respectively. Conclusions: Considering the high prevalence of illicit injecting drug use in Iran and MMT effectiveness in prevention of HCV infection, it is necessary to develop MMT centers at regional and national levels.

Abstract
Viral hepatitis B and C (HBV, HCV) disproportionately affect people who inject drugs (PWID) across the world. To date there has been little global action focusing on prevention, care and treatment of HBV and HCV among PWID. Here we report on the development process and discuss the implications of evidence informed WHO Guidelines for the Prevention of HBV and HCV in PWID. The World Health Organization (WHO) convened a Guideline Development Panel to develop recommendations on the prevention of HBV and HCV among PWID. The process followed the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. It included the development of PICO (Population, Interventions, Comparator, Outcomes) questions and conducting systematic reviews. Quality of evidence was classified into 4 levels: high, moderate, low, and very low. In the process of moving from evidence to recommendations, the following were considered: quality of evidence, balance of benefits and harms, community values and preferences and resource use. The WHO recommendations include the following for working with PWID: offer the rapid HBV vaccination regimen; offer incentives to increase uptake and completion of the HBV vaccine schedule; needle and syringe programs should also provide low dead-space syringes for distribution; and offer peer interventions to reduce the incidence of viral hepatitis. This guideline complements other WHO documents regarding PWID, including HIV prevention initiatives such as needle and syringe programs and opioid substitution therapy. This guidance offers a first step in the prevention of HBV and HCV among PWID. However, the lack of high quality evidence in this area necessitates further research and resources for implementation.
