Abstract
Despite promising steps towards the elimination of hepatitis C virus (HCV) in the UK, several indicators provide a cause for concern for future disease burden. We aimed to improve understanding of geographical variation in HCV-related severe liver disease and historic risk factor prevalence among clinic attendees in England and Scotland. We used metadata from 3829 HCV-positive patients consecutively enrolled into HCV Research UK from 48 hospital centres in England and Scotland during 2012-2014. Employing mixed-effects statistical modelling, several independent risk factors were identified: age 46-59 y (ORadj 3.06) and ≥60 y (ORadj 5.64) relative to <46 y, male relative to female sex (ORadj 1.58), high BMI (ORadj 1.73) and obesity (ORadj 2.81) relative to normal BMI, diabetes relative to no diabetes (ORadj 2.75), infection with HCV genotype (GT)-3 relative to GT-1 (ORadj 1.75), route of infection through blood products relative to injecting drug use (ORadj 1.40), and lower odds were associated with black ethnicity (ORadj 0.31) relative to white ethnicity. A small proportion of unexplained variation was attributed to differences between hospital centres and local health authorities. Our study provides a baseline measure of historic risk factor prevalence and potential geographical variation in healthcare provision, to support ongoing monitoring of HCV-related disease burden and the design of risk prevention measures.

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
Background/Aims This study aimed to elucidate the epidemiological and clinical characteristics of chronic hepatitis C (CHC) patients in South Korea from 2007 to 2017 and to compare the treatment patterns between two periods before and after the first approval of direct-acting antivirals (DAA) in South Korea in 2015. Methods This prospective, multicenter cohort enrolled 2,758 patients with hepatitis C virus (HCV) viremia at seven tertiary centers, and clinical data were prospectively collected with questionnaire surveys focused on lifetime risk factors related to HCV infection. Results The HCV patients had a mean age of 57.3 years (50.8% male). Among them, 14.3% showed a positive history of transfusion before HCV screening and 5.6% reported intravenous drug use (IVDU), with significant differences in these risk factors between men and women. The proportions of patients with chronic hepatitis, liver cirrhosis and hepatocellular carcinoma (HCC) were 69.5%, 18.9%, and 11.5%, respectively. The mean alanine aminotransaminase level was within the upper normal limit at 49.9%, and the major genotypes were 1b (48.2%) and 2 (46.4%). The overall treatment rate was 53.8%, showing a rapid transition from interferon-based therapy to DAA therapy. In the post-DAA-approval era, the untreated group was older, had a higher prevalence of HCC, and had less education than the treated group. Conclusions More than 90% of CHC patients were over 40 years old, the major genotypes were 1b and 2, and IVDU was observed in less than 6% of CHC patients. Approximately half of the patients underwent antiviral therapy even in the DAA era, showing an unmet need with regard to HCV elimination.

Abstract
The rate of clinical liver disease progression in this cohort of HCV mono-infected and HIV/HCV co-infected individuals was higher than previously reported. Risk of clinical liver disease progression was associated with level of immune suppression, and was more pronounced in women. Background. Hepatitis C virus (HCV) infection is a leading cause of liver-related morbidity and mortality in the United States, and injection drug users are at particularly high risk. Methods. This prospective observational cohort study assessed the rate of, and risk factors for, clinical liver disease progression in a cohort of HCV monoinfected and human immunodeficiency virus (HIV)/HCV coinfected drug users using unadjusted and multivariate Cox proportional hazards regression analyses. Results. Of 564 subjects including 421 (75%) with HIV/HCV coinfection and 143 with HCV monoinfection, 55 (10%) had clinical liver disease progression during follow-up with a rate of 25.3 events per 1000 person-years. In unadjusted analysis, there was an interaction between sex and HIV status. In sex-stratified multivariate analysis, HIV/HCV-coinfected women with CD4 <200 cells/mm3 had 9.99 times the risk of liver disease progression as HCV-monoinfected women (confidence interval [CI], 1.84–54.31; P = .008), and white women had a trend towards increased risk of liver disease progression compared with non-white women (hazard ratio, 2.84; CI, .93–8.68; P = .07). Human immunodeficiency virus/HCV-coinfected men with CD4 <200 cells/mm3 had 2.86 times the risk of liver disease progression as HCV-monoinfected men (CI, 1.23-6.65; P = .01). Conclusions. Hepatitis C virus-monoinfected and HIV/HCV-coinfected drug users had high rates of clinical liver disease progression. In those with HIV infection, liver disease progression was associated with advanced immune suppression. This effect was strikingly more pronounced in women than in men.

Abstract
OBJECTIVES The aim of this study was to describe the proportion of liver-related diseases (LRDs) as a cause of death in HIV-infected patients in France and to compare the results with data from our five previous surveys. METHODS In 2010, 24 clinical wards prospectively recorded all deaths occurring in around 26 000 HIV-infected patients who were regularly followed up. Results were compared with those of previous cross-sectional surveys conducted since 1995 using the same design. RESULTS Among 230 reported deaths, 46 (20%) were related to AIDS and 30 (13%) to chronic liver diseases. Eighty per cent of patients who died from LRDs had chronic hepatitis C, 16.7% of them being coinfected with hepatitis B virus (HBV). Among patients who died from an LRD, excessive alcohol consumption was reported in 41%. At death, 80% of patients had undetectable HIV viral load and the median CD4 cell count was 349 cells/μL. The proportion of deaths and the mortality rate attributable to LRDs significantly increased between 1995 and 2005 from 1.5% to 16.7% and from 1.2‰ to 2.0‰, respectively, whereas they tended to decrease in 2010 to 13% and 1.1‰, respectively. Among liver-related causes of death, the proportion represented by hepatocellular carcinoma (HCC) dramatically increased from 5% in 1995 to 40% in 2010 (p = 0.019). CONCLUSIONS The proportion of LRDs among causes of death in HIV-infected patients seems recently to have reached a plateau after a rapid increase during the decade 1995-2005. LRDs remain a leading cause of death in this population, mainly as a result of hepatitis C virus (HCV) coinfection, HCC representing almost half of liver-related causes of death.

Abstract
Killer immunoglobulin-like receptors and their human leukocyte antigen class I ligands have a critical role in natural killer cell response to viral pathogens and tumors. To investigate whether killer immunoglobulin-like receptor genes could influence the chronic course of hepatitis C virus infection and/or progression to hepatocellular carcinoma we retrospectively analyzed a cohort of 228 patients transplanted for hepatitis C virus-induced cirrhotic end stage liver disease, combined or not with hepatocellular carcinoma. We found that patients completely lacking activating killer immunoglobulin-like receptor genes had a high risk of developing hepatocellular carcinoma. Hepatitis C viral genotype and viral load are other risk factors that can influence the course of chronic hepatitis C virus infection. In our study, the risk conferred by hepatitis C viral genotypes was enhanced in patients lacking activating killer immunoglobulin-like receptors. These results point to an important role for activating killer immunoglobulin-like receptors in the control of hepatitis C virus infection and progression to hepatocellular carcinoma. In clinical practice, assessment of killer immunoglobulin-like receptor and hepatitis C viral genotype combinations should allow for more accurate monitoring of patients with chronic hepatitis C virus infection.

Abstract
BACKGROUND Hepatitis C virus (HCV)/human immunodeficiency virus (HIV) co-infection has become a serious public health problem especially in high risk groups such as injection drug users in China. However, the impact of HIV infection and antiretroviral therapy (ART) on HCV viral load which is usually regarded as a predictor of liver disease progress had not been well studied in this country. OBJECTIVES To explore correlations of HIV co-infection and ART with plasma HCV load among HCV-infected patients in an ethnic minority area in Yunnan Province, China. PATIENTS AND METHODS HCV/HIV co-infected patients and HCV mono-infected controls were examined and compared for plasma HCV RNA and related risk factors. RESULTS A total of 145 HCV/HIV co-infected patients and 25 HCV mono-infected controls were studied. The majority of the participants were male, belonged to an ethnic minority and were younger than 45 years old. HCV viral suppression rate with undetectable plasma HCV viral load was 28.3% in the HCV/HIV co-infected patients, 36% among HCV mono-infected controls and 29.4% overall. ART-prescribed HCV/HIV co-infected patients had significantly higher HCV viral loads (IQR: (3.80-6.44)*log(10) copies ml-1) than those naïve to ART (IQR: (undetectable-6.41)*log(10) copies ml-1) and HCV mono-infected patients (IQR: (undetectable-5.44)*log(10) copies ml-1). Men, from the Dai minority and those with more than six years education, were also shown to have a higher plasma HCV viral load,according to multiple logistic regression analysis. CONCLUSIONS ART potentially increases the plasma HCV viral load among HCV/HIV coinfected patients in an ethnic minority area in China. Future large scale prospective cohort studies are needed to address the controversy associated between HIV co-infection and the natural history of HCV.

Abstract
BACKGROUND Few studies have evaluated the histological aspects of hepatitis C virus (HCV) infection in hemodialysis patients and the factors related to the progression of hepatic fibrosis in this population have not been defined. AIM To evaluate the influence of host-related factors on the fibrosis progression in end-stage renal disease (ESRD) patients with HCV infection. METHODS HCV-infected ESRD patients who submitted to liver biopsy were included. The fibrosis stages were classified according to METAVIR scoring system. For the identification of factors associated with more advanced liver fibrosis, the patients were classified into two groups: group 1, absence of septal fibrosis (F0-1) and group 2, presence of septal fibrosis (F2-4). Groups 1 and 2 were compared regarding demographic, epidemiological, and laboratory variables and logistic regression analysis was used to identify the variables that were independently associated with the presence of septal fibrosis. RESULTS A total of 216 ESRD patients (63% men, 44+/-11 years) were included. In the histological analysis, the fibrosis stages were as follows: F0=36%, F1=41%, F2=12%, F3=7, and 4% had cirrhosis (F4). In the logistic regression model, the variables that were independently associated with the presence of septal fibrosis were duration of infection, estimated age at infection, coinfection with HBV and aspartate aminotransferase levels. CONCLUSION These findings support the importance of obtaining an adequate immune response to HBV vaccination and careful monitoring of liver disease in patients who become infected at an advanced age and/or those presenting elevated aspartate aminotransferase levels, as these are the main factors associated with the presence of septal fibrosis in ESRD patients.

Abstract
PURPOSE OF REVIEW A growing number of veterans in the Veterans Health Administration are coinfected with HIV and hepatitis C virus. This review covers timely research relative to comorbid conditions that are common in this population including psychiatric diagnoses, substance use disorders and neurocognitive problems. RECENT FINDINGS Current literature on the psychiatric, substance use disorders and cognitive problems of the coinfected population show that not only are rates of morbidity higher in the coinfected population but that this affects antiviral treatments as well. There is new evidence that brain injuries and infiltration of the virus into the central nervous system may be responsible for cognitive dysfunction. Cotesting, particularly in hepatitis C infected individuals, is not done routinely despite shared risk factors. SUMMARY With this understanding of the comorbidities of the coinfected population, integrated healthcare models involving mental health, internal medicine, substance abuse treatment and internal medicine are crucial to work with these medically and psychologically complex patients.

Abstract
OBJECTIVE The objective of this study was to determine the prevalence and genotype distribution of chronic hepatitis C virus (HCV) infection in a penitentiary population. The secondary objective was to describe histological findings in liver of the biopsied population, and identify risk factors associated with liver fibrosis and inflammatory activity. METHODS Among 800 inmates, 730 accepted HCV antibody screening and PCR confirmation. Sociodemographic, behavioral, and incarceration-related variables were analyzed. Liver biopsy was offered to individuals with chronic HCV infection. Advanced liver disease was defined as fibrosis 3 and/or an inflammatory activity index score 8). RESULTS HCV antibodies were found in 279 inmates. PCR confirmed HCV infection in 250 inmates, yielding a prevalence of 34.2% (95% confidence interval [CI]: 30.8-37.8). Intravenous drug use was independently associated with HCV infection, odds ratio (OR) 51.7 (95% CI: 31-86). Genotypes were 1a 32.9%, 3 29.7%, 1b 18.4% and 4 17.1%. Fifty-one liver biopsies were performed; advanced liver disease was found in 7 patients (13.7%) based on fibrosis and in 31 patients (60.7%) based on the inflammatory activity index. High AST and ALT levels were associated with advanced liver disease established on both fibrosis and inflammatory activity (P<.05). Lengthy intravenous drug use was associated with inflammatory activity (P=.02; OR 1.2; 95% CI: 1.03-1.7). CONCLUSIONS Persistent HCV infection is highly prevalent among prison inmates and is associated with intravenous drug abuse. HCV genotype diversity is higher in prison inmates than in the general population. Higher transaminase levels are associated with advanced liver disease.

Abstract
Two national HCV projections have been published in France which assumed that a part of observed hepatocellular carcinoma (HCC) deaths is a consequence of HCV epidemic. They applied the back-calculation method, in combination with a Markov model, to reconstruct the past history of HCV infection and then to predict HCV-related mortality. A preliminary model was first developed in the absence of effective therapy. It allowed testing many assumptions to model HCV natural history that were compatible with observed incidence of HCV-related HCC deaths. This model was then updated to take into account the availability of treatment and more recent epidemiological data. These two models are described in detail and results are discussed with a view to addressing the models' limitations. The models offered a useful tool to assess public health policy scenarios in planning healthcare responses to the HCV epidemic.

Abstract
Infection with hepatitis C virus (HCV) is a major cause of chronic liver disease. Hepatic fibrosis may develop in subjects with chronic HCV infection, culminating in cirrhosis and an increased risk of hepatocellular carcinoma. The rate of development of fibrosis varies substantially between individuals; while it is influenced by a number of demographic and environmental factors, these account for only a small proportion of the variability. There are no clinical markers or tests that predict the rate of fibrosis progression in an individual subject. Thus, there has been increasing interest in the influence of host genetic factors on the rate of disease progression, and whether a genetic signature can be developed to reliably identify individuals at risk of severe disease. Numerous case-control, candidate gene, allele-association studies have examined the relationship between host single nucleotide polymorphisms or other genetic mutations and fibrosis in patients with chronic HCV infection. However, these studies have generally been irreproducible and disappointing. As seen with genetic studies for other diseases, small study cohorts and poor study design have contributed to limited meaningful findings. The successful determination of genetic signatures for fibrosis progression in chronic HCV will require multicenter collaborations using genome-wide association studies, with large, phenotypically well-defined sample sets. While these studies will require a significant financial commitment, a successful outcome offers the potential for personalized therapy and better patient management.

Abstract
OBJECTIVES To estimate stage-specific transition probabilities in individuals coinfected with HIV and hepatitis C virus (HCV), to examine the effect of covariates on these rates, and to investigate the effect of HIV on HCV-related cirrhosis in the era of highly active antiretroviral therapy (HAART). DESIGN Systematic review of natural history studies among HCV-infected individuals. METHODS Markov maximum likelihood estimation method was used to estimate stage-specific transition probabilities. A meta-analysis was performed to obtain pooled transition probabilities, and a meta-regression to investigate the impact of covariates on these rates. Risk of cirrhosis between individuals monoinfected with HCV and coinfected with HIV/HCV were compared by HAART status. RESULTS The estimated mean (95% confidence intervals) annual transition probabilities of 3567 individuals coinfected with HIV/HCV (n = 17 studies) were as follows: fibrosis stage (F) F0 --> F1 0.122 (0.098-0.153); F1 --> F2 0.115 (0.095-0.140); F2 --> F3 0.124 (0.097-0.159); and F3 --> F4 0.115 (0.098-0.135) units/year. The prevalence of cirrhosis after 20 and 30 years of HCV infection was 21% (16-28%) and 49% (40-59%), respectively. Longer duration of HCV infection was significantly associated with slower rate of fibrosis progression. The overall rate ratio of cirrhosis between individuals coinfected with HIV/HCV and monoinfected with HCV (n = 27 studies) was 2.1 (1.5-3.0), 2.5 (1.8-3.4) in the non-HAART group, and 1.7 (1.1-2.8) in the HAART group. CONCLUSION The rate of fibrosis progression among individuals coinfected with HIV/HCV appears constant. Our results confirm that chronic hepatitis C outcomes are worse among coinfected individuals. Over the period studied, HAART did not appear to fully correct the adverse effect of HIV infection on HCV prognosis.

Abstract
Progression of chronic hepatitis is highly variable among individuals, as the result of several host, viral and environmental factors. The latter have been extensively investigated in order to ameliorate hepatitis C outcome, particularly in difficult-to-treat patients. Over the last decade, several studies have shown that a combination of HCV infection and high levels of alcohol abuse results in synergistic acceleration of liver fibrogenesis. In addition, recent data indicate that light alcohol intake may also exacerbate fibrosis progression. It has also been suggested that cigarette smoking may enhance activity grade in patients with chronic hepatitis C, thereby increasing progression of fibrosis. This assumption mostly relies on epidemiological evidences in the absence of pathogenic studies. Finally, cannabis use is increasingly emerging as a novel co-morbidity in patients with chronic hepatitis C. Indeed, regular cannabis smoking is an independent predictor of both fibrosis and steatosis severity in infected patients. In addition, experimental studies have shown that cannabinoid CB1 receptors enhance liver fibrogenesis and steatogenesis by distinct mechanisms, therefore strongly supporting epidemiological findings. Altogether, patients should be informed of the deleterious impact of alcohol, tobacco and cannabis use and should be offered appropriate support to achieve abstinence.

Abstract
HCV and HIV infections are very common among injection drug users (IDUs). It is well known that 80-90% of HIV-infected IDUs are also infected with HCV. Furthermore, patients with HCV/HIV co-infection are at a higher risk of progressing to end-stage liver disease, namely cirrhosis. Even though there is increasing global awareness of HCV/HIV co-infection and extended therapeutic programs for this infected population, little is known about the HCV/HIV pathophysiology that mediates the rapid progression to hepatic disease. Liver disease caused by HCV/HIV co-infection is characterized by inflammation and cell-death. Recent reports suggest that the HIV and HCV envelope proteins may induce apoptosis and inflammation in hepatocytes via a novel pathway involving collaborative signaling. Moreover, HCV/HIV co-infection may also alter the cytokine production in vivo. Further studies to elucidate the molecular mechanisms of HCV and HIV-mediated pathogenesis will help in the development of therapeutic strategies against HCV/HIV co-infection in these patients.

Abstract
BACKGROUND & AIMS We systematically reviewed the literature examining the association of human immunodeficiency virus (HIV) and antiretroviral therapy (ART) with liver disease in patients with hepatitis C virus (HCV) infection. METHODS PubMed was searched for studies examining hepatic fibrosis, cirrhosis, decompensated liver disease, hepatocellular carcinoma, and liver-related death. Thirty-nine reports (describing 34 unique studies) met inclusion criteria. Information was abstracted on study design, sampling frame, inclusion/exclusion criteria, sample size, results, and covariates used for adjustment. Because of the heterogeneity among study designs, a meta-analysis was not conducted. RESULTS Nine of the 12 cross-sectional studies showed a statistically significant association between HIV co-infection and fibrosis or cirrhosis, whereas 7 retrospective cohort studies were inconsistent. Six studies examined decompensated liver disease as the outcome: 5 of these found a significantly increased risk in patients with HIV co-infection. The 7 studies examining liver-related death showed a trend toward an association with HIV co-infection, although only 4 were statistically significant. Four studies examined the effect of HIV on hepatocellular carcinoma, 2 of which found no association. Of 10 studies that investigated the effect of ART on the risk of liver disease, half reported a significant protective association. CONCLUSIONS HIV co-infection is associated with an increased risk of advanced liver disease in hepatitis C virus-infected patients. Data on hepatocellular carcinoma are sparse, but an association is plausible given the increased risk of advanced liver disease. In contrast, data for an effect of ART are plentiful, but findings are inconsistent. More robust studies are needed on this topic.

Abstract
BACKGROUND Since the discovery of the hepatitis C virus (HCV), extensive literature has emerged on alcohol and HCV interaction. GOAL To understand the impact of alcohol and HCV infection on the severity of liver disease and the mechanisms of interaction between the two. STUDY Of 1269 articles (1991 to 2006) searched through MEDLINE and cited cross references, 133 were thoroughly reviewed to assess: (a) prevalence of combined alcohol use and HCV, (b) severity of liver disease (c) treatment response, and (d) mechanisms of interaction between HCV and alcohol. Data on study design, patient demographics, diagnostic tests used, and study outcomes were extracted for critical analysis. RESULTS Prevalence of HCV is 3-fold to 30-fold higher in alcoholics compared with the general population. Patients with HCV infection and alcohol abuse develop more severe fibrosis with higher rate of cirrhosis and hepatocellular cancer compared with nondrinkers. Increased oxidative stress seems to be the dominant mechanism for this synergism between alcohol and the HCV. Abstinence is the key to the management of liver disease due to HCV and alcohol. Data have shown that lower response rates to interferon in alcoholics with HCV infection are likely due to noncompliance. CONCLUSIONS Alcoholics with HCV infection have more severe liver disease compared with nondrinkers. Patients should be encouraged to enroll in rehabilitation programs so as to improve treatment adherence and response.

Abstract
Hepatitis virus coinfections [HBV plus HCV coinfection (HBV/HCV) or HBV plus HDV coinfection (HBV/HDV)] may progress more rapidly to cirrhosis than hepatitis B or C monoinfections in immunocompetent patients. Only limited information is available on the outcome of coinfected patients after liver transplantation. We studied survival rates of 204 patients with viral hepatitis transplanted at our center between 1972 and 1997. HBV/HDV and HBV/HCV coinfections were present in 23 and nine individuals, respectively, while 97 patients had monoinfection by HCV and 75 had HBV monoinfection. Survival of coinfected patients was significantly longer than that of monoinfected patients (14.4 +/- 0.9 vs. 8.5 +/- 0.6 yr; p = 0.0003). The same was true for graft survival (p = 0.0002). In Cox's regression, viral coinfection (p = 0.0001), absence of hepatocellular carcinoma (HCC) (p = 0.00001) and no retransplantation (p = 0.02) were independently associated with patient survival. After exclusion of patients with HCC (n = 62), survival of coinfected patients was still significantly longer than that of monoinfected individuals (p = 0.002). The improved outcome was similar for both HBV/HDV and HBV/HCV coinfections. In contrast to immunocompetent patients, individuals with multiple hepatitis virus infections had an improved outcome after liver transplantation. Thus, viral coinfections may be associated with ameliorated courses of diseases under certain conditions.

Abstract
High levels of hepatitis C virus (HCV) RNA are associated with a poor response to treatment of chronic hepatitis C, and a substantial reduction in HCV RNA levels predicts a favorable treatment response. We prospectively studied time-dependent and time-independent predictors of HCV RNA levels in 264 drug users with chronic HCV infection. Interviews on medical history and high-risk behaviors, phlebotomy for HIV viral load, serum HCV RNA levels as measured by the COBAS Amplicor HCV Monitor (Roche Diagnostics, Branchburg, NJ), and a lymphocyte subset assay were performed. Factors associated with HCV RNA levels over time were analyzed using a linear mixed model. Nearly 70% of the participants were men, two thirds were Hispanic, and the mean age was 46 years. HCV RNA levels increased over time. Older age (P < 0.001), HIV seropositivity (P = 0.03), and HCV nongenotype 1 (P = 0.05) were predictors of higher HCV RNA levels on multivariate analysis. Among 142 HIV-seropositive participants, a detectable HIV-1 viral load (P < 0.001) and recent alcohol use (P = 0.02) were predictors of higher HCV RNA levels. The predictors of higher HCV RNA levels found in this longitudinal study are consistent with those of prior cross-sectional studies. Further studies are warranted to determine if treatment of alcohol use affects HCV RNA levels.

Abstract
Co-infection by the hepatitis C virus (HCV) is observed in up to 30% of HIV-infected individuals. In studies conducted in the 'pre-HAART era', the late consequences of HCV-related chronic liver disease were overshadowed by extra-hepatic causes of deaths, related to severe immune deficiency, and the impact of HCV infection on mortality of HIV-infected patients was low. While the development of HAART has resulted in a significant decrease in morbidity and mortality amongst HIV-infected patients, this clear benefit allowed the expression of liver-related complications associated with HCV chronic infection. The impact of HCV on HIV remains debated but HIV infection significantly modifies the natural history of HCV infection. HIV infection increases levels of HCV viraemia by 2- to 8-fold, resulting in a significant decrease in spontaneous recovery of acute hepatitis. HIV co-infection also worsens the histological course of HCV infection by increasing and accelerating the risk of cirrhosis or leading to rare but lethal fibrosing cholestatic hepatitis. Liver disease is now one of the leading causes of morbidity and mortality in co-infected patients, even if HAART and especially protease inhibitors, may decrease the severity of the liver disease and the liver-related mortality. Several non-exclusive pathogenic processes explain the increasing rate of liver complications associated with HCV-related liver disease.

Abstract
Cirrhosis is the end-stage consequence of fibrosis progression in patients with chronic hepatitis C. The median time from infection to cirrhosis is 30 years, with a high inter-individual variability, which is now better understood. Several factors have been clearly shown to be associated with fibrosis progression rate: duration of infection, age, male gender, alcohol consumption, HIV co-infection and low CD4 count. Metabolic conditions such as steatosis, being overweight and diabetes are emerging as independent co-factors of fibrogenesis. The recent validation of non-invasive biomarkers should facilitate the study of fibrosis progression in large populations.

Abstract
BACKGROUND & AIMS A convincing, yet inconsistent, pattern has emerged that demonstrates increased progression of HCV-related liver disease with heavy alcohol use. The aim was to perform a meta-analysis to quantify the effect of alcohol on cirrhosis risk among persons infected with HCV. METHODS A meta-analysis of 20 articles, involving more than 15,000 HCV chronically infected persons, published between 1995 and 2004 was undertaken to explore the relationship between advanced liver disease and the consumption of alcohol. RESULTS The pooled relative risk of cirrhosis associated with heavy alcohol intake (defined in the range of at least 210-560 g per week) was 2.33 (95% confidence interval, 1.67-3.26) by the random effects model. The risk of HCV-related liver disease associated with heavy alcohol intake increased with severity of the outcome; the lowest (1.63; 95% confidence interval, 1.22-2.17) and highest (3.54; 2.14-5.85) pooled relative risk estimates were obtained for advanced fibrosis and decompensated cirrhosis, respectively. The regression effect of alcohol might, however, be underestimated in studies investigating the risk of HCV-related cirrhosis because they necessarily include patients undergoing liver biopsy and could therefore under-represent heavy alcohol users. CONCLUSIONS The evidence overwhelmingly shows a worsened outcome for those with chronic HCV and concurrent alcohol use. Studies varied widely in their definition of significant alcohol intake, and so the true threshold above which alcohol accelerates HCV disease progression remains uncertain. Alcohol consumption should be minimized as much as possible in those who have chronic HCV until a safe threshold is more definitively determined.

Abstract
Nearly 40% of human immunodeficiency virus- (HIV-) infected veterans on highly active antiretroviral therapy (HAART) in the United States are coinfected with hepatitis C virus (HCV). With the increased survival due to declining opportunistic infections as a result of HAART, HCV-associated liver disease has become a leading cause of death in HIV-infected individuals. HCV infection has been shown to lead to rapid progression of HCV-related liver disease in HIV infection. Results from recent clinical trials in HIV/HCV-coinfected patients show improved response rates using pegylated formulations of interferon plus ribavirin when compared to standard interferon plus ribavirin. However, the treatment of HCV in HIV/HCV-coinfected patients can be complicated by the hepatotoxic and myelosuppressive effects of HIV therapy and HIV infection itself. Prior to initiating HCV therapy, HIV therapy should be optimized by improving immune suppression and avoiding specific antiretroviral drugs that may cause hepatotoxicity and myelosuppression. In the event of treatment-related neutropenia or anemia during HCV therapy, the use of growth factors should be considered to maximize sustained virologic response to HCV therapy. In HIV/HCV-coinfected patients with end-stage liver disease, liver transplantation is being investigated and shows promise as a potential therapeutic option. With the recent advances in the treatment of HCV in HIV/HCV-coinfected individuals, all HIV/HCV-coinfected patients eligible for HCV treatment should be evaluated for HCV combination therapy with careful consideration of their HIV disease.

Abstract
Liver disease in patients coinfected with HIV and hepatitis C virus (HCV) has received increasing attention in recent years. Steatosis is accepted as an important contributor to liver disease in patients with HCV, but despite coinfected patients having several reasons to have steatosis, the prevalence and significance of such changes has received scant attention. We examined steatosis in an unselected cohort of coinfected patients and compared its prevalence and predictors with findings in monoinfected patients, where these relationships have been established. We studied 92 coinfected and 372 monoinfected patients undergoing staging liver biopsy. Baseline characteristics of the two groups differed significantly, pointing at different contributors to steatosis in each. Histological inflammation and fibrosis were very similar in the two groups, but steatosis was less in coinfected patients. Steatosis had a univariate association with fibrosis in both groups, but retained a multivariate association only in monoinfected patients. Other multivariate predictors of steatosis in monoinfected patients were the accepted variables of elevated body mass index, male sex, and genotype 3a infection, as well as age. In coinfected patients, however, age was the only multivariate predictor. Undetectable HIV viral load was associated with steatosis in coinfected patients in univariate analysis, but highly active antiretroviral therapy or its individual components could not be initially linked to steatosis. In conclusion, steatosis is less common in HIV/HCV coinfected patients than similar HCV monoinfected patients, and predictors of steatosis differ between the two groups.

Abstract
In at-risk populations, shared routes of transmission lead to high rates of concordance between infection with human immunodeficiency virus (HIV) type 1 and hepatitis C virus (HCV). In the era of highly active antiretroviral therapy (HAART), end-stage liver disease (ESLD) has emerged as a leading cause of mortality in coinfected patients. HAART-related toxicities have been implicated, especially when given to patients with viral hepatitis. Rates of response to treatment for HCV infection in coinfected patients continue to lag behind those in monoinfected patients, even with the advent of pegylated interferons. Liver transplantation has been approached with caution in this population because of concern about the sequelae of immunosuppression and HAART-related hepatotoxicity, and results have been conflicting. Clinical and serological markers of ESLD in coinfected patients, management of cirrhosis, and the appropriateness of transplantation are discussed.

Abstract
BACKGROUND Liver failure is an increasing cause of death in human immunodeficiency virus-hepatitis C virus (HIV-HCV) co-infected patients. Here, histopathological features of fatal liver disease in HIV-HCV co-infected patients were comparatively assessed. METHODS Liver biopsies of seven HIV-HCV co-infected patients with clinically imminent liver death and advanced immune deficiency were studied. Biopsies of seven asymptomatic patients with stable hepatic and immune functions, who were matched according to their documented duration of HIV-HCV co-infection, served as controls. Inflammatory and fibrotic changes as well as hepatocellular steatosis and cholestasis were assessed semiquantitatively by established scores. RESULTS All patients with fatal liver disease had severe immunodeficiency and jaundice, while biliary ducts were patent. Unexpectedly, the extent of hepatic steatosis, inflammatory activity and fibrosis was strikingly similar in both study groups. Importantly, liver failure was observed even in the absence of marked fibrosis. Lobular bilirubinostasis was the only feature that significantly distinguished patients with advanced immunodeficiency and fatal liver disease from the control group. CONCLUSION Thus, rapid deterioration of liver function and death can occur in HIV-HCV co-infected patients with advanced immunodeficiency even when liver histology does not reveal markers of end-stage liver disease. Jaundice and marked bilirubinostasis in the absence of biliary tract obstruction seem to herald this complication of chronic hepatitis C in HIV infection.

Abstract
BACKGROUND Despite previous study, it remains unclear whether hepatitis C virus (HCV) coinfection affects the progression of human immunodeficiency virus (HIV) type 1 infection. The Women and Infants Transmission Study provided an opportunity to assess this issue. METHODS Longitudinal data on 652 HIV-1-infected women enrolled in the study before the availability of highly active antiretroviral therapy (HAART; 1989-1995) were analyzed. Random effects models were used to determine whether HCV coinfection was associated with different CD4+ cell percentages and HIV-1 RNA levels over time, and Cox proportional hazards models were used to compare the rates of clinical progression to acquired immunodeficiency syndrome (AIDS) or death. RESULTS Of 652 women, 190 (29%) were HCV infected. During follow-up, 19% of women were exposed to HAART. After controlling for indicators of disease progression (CD4+ cell percentages and HIV-1 RNA levels determined closest to the time of delivery in pregnant women), ongoing drug use, receipt of antiretroviral therapy, and other important covariates, no differences were detected in the HIV-1 RNA levels, but the CD4+ cell percentages were slightly higher in HCV-infected women than in HCV-uninfected women. During follow-up, 48 women had progression to a first clinical AIDS-defining illness (ADI), and 26 died with no documented antecedent ADI. In multivariable analyses, HCV-infected participants did not have faster progression to a first class C AIDS-defining event or death (relative hazard, 0.75; 95% confidence interval, 0.37-1.53). CONCLUSIONS In this cohort, the rate of clinical progression of HIV-1 infection was not greater for HCV-infected women.

Abstract
Retrospective cross-sectional studies indicate that 20% with chronic hepatitis C virus (HCV) infection become cirrhotic within 20 years. Known risk factors for advanced hepatic fibrosis include age at time of infection, male sex, excess alcohol consumption and cytokine polymorphisms. Prospective study to assess and identify factors predictive of change in hepatic fibrosis stage in chronic HCV infection by interval protocol liver biopsy was performed. One hundred and five patients with paired liver biopsy specimens separated by a mean 41 months were recruited from a cohort of 823 HCV carriers. Five per cent developed worsening hepatic fibrosis by more than two stages. In 43% there was no change in fibrosis stage. Excessive alcohol intake currently (P = 0.037) or previously (P = 0.07) predicted progression. In contrast, always having a normal alanine transaminase (P = 0.038) and always being negative in serum for HCV RNA (P =0.067) predicted no progression. Three models were developed to predict outcome. Progressive fibrosis was predicted by baseline fibrosis (P = 0.018), steatosis (P = 0.02) and age (P = 0.017). The rate of progressive fibrosis was predicted by baseline fibrosis (P = 0.0002), steatosis (P =0.039) and lobular inflammation (P = 0.09). Fibrosis stage on the second biopsy was predicted by baseline fibrosis alone (P = 0.01). The rate of progression varies widely. Alcohol misuse is an important co-factor. Progressive fibrosis can be predicted at first liver biopsy, where baseline fibrosis is most critical, allowing targeted therapy for those with early disease and a significant risk of progression.

Abstract
OBJECTIVES This study was conducted to determine whether HIV coinfection increases the risk of cirrhosis in HCV-infected patients in the HAART and pre-HAART eras. Further, the risk of hepatocellular carcinoma was also examined. METHODS This retrospective cohort study was conducted among HCV-infected veterans who were seen at one of the 172 Veterans Health Administration hospitals between October 1, 1991 and September 30, 2000. Patients with prerecorded advanced liver disease were excluded. Incidence rates, cumulative incidence, and Cox proportional hazard ratios were calculated. RESULTS There were 26,641 patients with HCV-only and 4,761 patients with HCV-HIV coinfection. The unadjusted incidence rate of cirrhosis was lower in patients with coinfection than HCV-only (p < 0.01). After controlling for demographics and confounders (including alcoholism and chronic hepatitis B), coinfection was not significantly associated with cirrhosis. However, there was an increased risk of cirrhosis in patients with coinfection compared to HCV-only during the pre-HAART era (before October 1, 1996) (hazard ratio = 1.48, 1.06-2.07, p= 0.02), but not among patients who entered the cohort during the HAART era. The unadjusted incidence rate of hepatocellular carcinoma in patients with coinfection and HCV-only was 1.3 and 2/1,000 person-years, respectively (p= 0.04). In the multivariate model, coinfection was not associated with hepatocellular carcinoma (hazard ratio = 0.84, p= 0.40). CONCLUSIONS Coinfection was a significant risk factor for cirrhosis only during the pre-HAART era and was not associated with hepatocellular carcinoma, irrespective of time period.

Abstract
BACKGROUND The deterioration of chronic hepatitis C is frequent in kidney recipients and results in a decrease in survival of patients and allografts. Interferon is contraindicated because of the risk of rejection and its low efficacy. The aim of this study was to analyze the biologic, virologic, and histopathologic efficacy of ribavirin alone in kidney allograft recipients with hepatitis C. METHODS Thirteen kidney recipients (eight men and five women, 46+/-11 years of age) with severe Metavir score of fibrosis (eight F3 and five F4) were treated with ribavirin alone during 22.4+/-13.9 months. Liver biopsy was performed before and during therapy, with a mean interval time of 5.7+/-9.3 years. RESULTS The transaminase level decreased significantly (128+/-77 vs. 53+/-28, P=0.001) without significant change of serum quantitative hepatitis C virus load. The comparison of pretreatment and on-treatment biopsy specimens showed a significant decrease in the activity Metavir score (1.23+/-1.01 vs. 2.46+/-0.78, P=0.05) and a nonsignificant trend for a decrease in the fibrosis score. Ribavirin tolerance was fair, and only one patient required erythropoietin therapy. CONCLUSIONS Ribavirin alone in kidney allograft recipients results in biologic and histologic improvement without a virologic response and is reasonably well tolerated.

Abstract
BACKGROUND The impact of immune reconstitution on liver fibrosis in HIV/hepatitis C virus (HCV) patients is unknown. In this case-control study, we investigated the impact of HIV infection on the severity of liver fibrosis and identified related factors. METHODS We studied 116 HIV/HCV patients and 235 HCV only patients all untreated for HCV. Each co-infected patient was matched with two singly-infected patients according to gender, age at contamination and duration of infection. Liver biopsy was analysed using the METAVIR score. RESULTS Alcohol consumption and route of contamination differed between HCV-infected and HCV/HIV co-infected patients. Among co-infected patients, a F3-F4 Metavir score was significantly more frequent than in mono-infected patients. Co-infected patients with severe fibrosis (F3-F4) had higher transaminase, ferritin levels and lower CD4 T-cell count than patients with none to moderate fibrosis (F0-F2). Although median duration of treatment with nucleoside analogues, non-nucleoside analogues and protease inhibitors were comparable in both groups, the delay between the presumed date of contamination and treatment initiation with highly active antiretroviral therapy (HAART) was significantly longer for patients with severe fibrosis than those with none to moderate fibrosis. Finally, the mean rate of fibrosis progression was significantly slower among patients exposed to HAART. CONCLUSION Early antiretroviral therapy in co-infected HIV-HCV patients may slow liver fibrosis progression.

Abstract
Liver transplantation (LT) in human immunodeficiency virus (HIV)-positive individuals is considered to be an experimental therapy with limited reported worldwide experience, and little long-term survival data. Published data suggest that the short-term outcome is encouraging in selected patients. Here, we report our experience in 14 HIV-infected liver allograft recipients, and compare outcomes between those coinfected with hepatitis C virus (HCV) and the non-HCV group. A total of 14 HIV-infected patients (12 male, 2 female, age range 26-59 years) underwent LT between January 1995 and April 2003. Indications for LT were HCV (n = 7), hepatitis B virus (HBV; n = 4), alcohol-induced liver disease (n = 2), and seronegative hepatitis (n = 1); 3 patients presented with acute liver failure. At LT, CD4 cell counts (T-helper cells that are targets for HIV) ranged from 124 to 500 cells/microL (mean 264), and HIV viral loads from <50 to 197,000 copies/mL. Nine of 12 patients were exposed to highly active antiretroviral therapy (HAART) before LT. In the non-HCV group (n = 7), all patients are alive, all surviving more than 365 days (range 668-2,661 days). No patient has experienced HBV recurrence, and graft function is normal in all 7 patients. However, 5 of 7 HCV-infected patients died after LT at 95-784 days (median 161 days). A total of 4 patients died of complications due to recurrent HCV infection and sepsis, despite antiviral therapy in 3 of them. A total of 3 patients experienced complications relating to HAART therapy. In conclusion, outcome of LT in HIV-infected patients with HBV or other causes of chronic liver disease indicates that LT is an acceptable therapeutic option in selected patients. However, longer follow-up in larger series is required before a conclusive directive can be provided for HCV / HIV coinfected patients requiring LT.

Abstract
The objective of this study was to assess the prevalence of hepatitis B virus and possible risk factors for this disease in 401 patients infected with the human immunodeficiency virus, followed at the University Hospital of the Ribeirão Preto Medical School, São Paulo State University. Each participant was submitted to a specific questionnaire and had a blood sample tested for the serologic markers HBsAg, total anti-HBcAg, anti-HBsAg and anti-HCV, using ELISA technique. The overall prevalence of hepatitis B markers was 40.9%, with 8.5% for HBsAg, 39.7% for total anti-HBcAg and 5.5% for anti-HBsAg. The variables that showed association with HBV were: age, higher education level, history of jaundice, time spent in prison, having a homosexual partner and positive markers for anti-HCV. Co-infection HBV/HCV was present in 20.4% of the participants.

Abstract
BACKGROUND Although hepatitis C virus (HCV) recurrence is almost universal after orthotopic liver transplantation (OLT), the impact of viral infection on liver graft is highly variable and difficult to predict. Because of the possible relationship between replicative senescence (RS) and the accelerated development of liver fibrosis, we aimed to assess the potential role of RS in the severity of HCV-related chronic hepatitis recurrence after OLT. METHODS One hundred three liver biopsies from 56 patients receiving transplants for HCV-related cirrhosis were studied, including 30 revascularization biopsies and 52 and 21 biopsies performed during and beyond the first year of OLT, respectively. The presence of senescent cells in liver grafts was assessed by the senescence-associated beta-galactosidase (SA-beta-Gal) staining method. Chronic hepatitis was defined by fibrosis stage and necrotico-inflammatory activity grade using the METAVIR score. RESULTS A total of 34 of the 103 (33%) frozen liver biopsies displayed SA-beta-Gal-positive cells, including 6 (20%) of the revascularization biopsies, 14 (34%) of the biopsies performed within the first year, and 10 (46%) of the biopsies performed beyond 1 year of follow-up. The presence of senescent cells in revascularization biopsies was significantly associated with the degree of ischemic necrosis at time of OLT (P = 0.01) and hepatitis C recurrence in the first year after OLT (P = 0.05). Furthermore, the presence of RS in the biopsy performed within the first year was associated with further development of fibrosis (P = 0.05). CONCLUSIONS These data show that RS has a significant impact upon the course of liver transplantation, especially in the long-term progression of fibrosis observed in HCV-infected patients.

Abstract
Liver enzyme elevations are common in human immunodeficiency virus (HIV)-infected patients, and their diagnosis or management may be difficult because of the intricacies of the pathogenic mechanisms involved. These include hepatotoxicity related to the highly active antiretroviral therapy (HAART) regimen, idiosyncratic or immunoallergic mechanisms, and direct cytotoxicity enhanced by an underlying liver disease. Liver enzyme abnormalities may also reflect hepatitis B (HBV) or hepatitis C (HCV) infection, which each have their own risks for chronic immune-mediated liver disease (including hepatitis flare after immune reconstitution) and of direct cytotoxicity. Finally, other factors may affect liver deterioration, including alcohol-related liver disease, nonalcoholic steatohepatitis associated with metabolic syndromes (e.g., hyperlipidemia, diabetes, or being overweight) that are potentially HAART related, and use of medication or illicit drugs (e.g., methamphetamine). A better understanding of these complex interactions, including adjustments of dosages of antiretroviral drugs, will probably help in the management of HIV-infected patients with liver enzyme abnormalities.

Abstract
We analysed liver histology findings in a large cohort of patients with chronic hepatitis C and in roughly half of them their response to interferon-alpha-based on iron parameters and HFE status. Histological activity and virological response to antiviral therapy (n = 146) were analysed in 273 immunocompetent and nonalcoholic patients with chronic hepatitis C, in terms of serum iron load, intrahepatic iron load (n = 110) and HFE mutations. Patients who were heterozygous for the C282Y and H63D mutations exhibited higher iron serum parameters than subjects without these mutations. The intrahepatic iron load was higher in H63D patients only. No association was observed between HFE mutations and histological activity. Increased iron parameters were associated with liver disease severity by univariate analysis only. Genotype 1 and ferritinaemia were associated with a poor response to antiviral therapy, whereas the H63D mutation emerged as a positive predictive factor for end of treatment and sustained antiviral response. Therefore, in chronic hepatitis C patients serum and intrahepatic iron levels were weakly correlated with histological activity, while HFE mutations were not. As for the response to interferon-alpha, elevated ferritinaemia constituted a negative predictive factor whereas the H63D mutation was a positive one. The H63D mutation might form part of an immunogenetic profile influencing the response to interferon therapy.

Abstract
Heavy alcohol use contributes to liver disease in the setting of chronic hepatitis C virus (HCV) infection. Whether this is true for light or moderate alcohol use has not been demonstrated. Light alcohol use has survival benefits at a population level and is practiced by most patients with chronic HCV infection. In this study, 800 patients with HCV undergoing liver biopsy at three sites had detailed alcohol histories recorded and the relationship between alcohol and hepatic fibrosis was assessed. On univariate analysis, heavy alcohol use (>50 g/day) was associated with an increase in mean fibrosis (P =.01). Such an association could not be demonstrated for light and moderate alcohol use. For each category of alcohol intake (none, light, moderate, and heavy), a spectrum of fibrosis was observed. On multivariate analysis, age, serum alanine aminotransferase (ALT), and histological inflammation were the independent predictors of fibrosis (P = <.0001,.0003, <.0001, respectively). In conclusion, heavy alcohol use exerts a greater effect on fibrosis than light or moderate use. There is a range of fibrosis at each level of alcohol use. Age, serum ALT, and inflammation are independently associated with fibrosis in multivariate analysis, highlighting the fact that variables other than alcohol intake predominate in the production of hepatic fibrosis.

Abstract
Predictors of hepatitis C virus (HCV)-related liver disease posttransplantation are still unclear. The impact of HCV genotype on outcome of transplantation has been studied, but conclusions are not in agreement. The role of HCV genotype 4 on the result of liver transplantation requires further study. The aim of this study is to examine the outcome of liver transplantation for patients with HCV genotype-4 infection. The study group included 128 patients who underwent transplantation for HCV infection: 28 patients, genotype 1; 11 patients, genotype 2; 19 patients, genotype 3; and 32 patients, genotype 4. For 64 of 128 patients, genotype was known and an assessable histological specimen was available. Median interval from transplantation to biopsy was 1.92 years (range, 0.24 to 11.48 years). Twenty-six percent of HCV genotype-4 patients developed either severe fibrosis or cirrhosis versus 6.7% in the genotype non-4 group (P =.04). A statistically significant greater fibrosis progression rate was observed in genotype-4 than genotype non-4 patients. In univariate and multivariate analysis, rapid liver fibrosis was associated with the presence of HCV genotype-4 infection. In addition, donor and recipient age and graft warm ischemic time also were associated with rate of fibrosis progression. Five-year cumulative rates for the development of cirrhosis or severe liver fibrosis were 84% in genotype-4 and 24% in genotype non-4 patients (P =.02). Five-year survival rates for patients with genotypes 1, 2/3, and 4 were 72%, 80%, and 79%, respectively (P =.8). In conclusion, 5-year survival for patients who underwent transplantation for HCV genotype-4 infection was similar to that of genotype non-4 patients; however, more severe fibrosis and rapid fibrosis progression was observed after transplantation in patients with genotype-4 infection.

Abstract
Genome heterogeneity may be related to the wide variability of clinical and pathological features in hepatitis C virus (HCV)-related chronic liver disease. This paper addresses the possible association between HCV subtypes and clinical and histological features of chronically infected patients. Sixty-eight consecutive liver biopsies of chronic hepatitis constituted the basis of the study. HCV genotyping was performed on frozen tissue. Grading of necroinflammatory activity and staging of fibrosis were histologically assessed. Serologic HCV-RNA and liver function were assessed at the same time. All information was compared with clinical data including age, sex, HCV serology, and probable data and route of infection. Two cases were excluded as inadequate tissue was available. Five cases were negative to HCV-RNA in both serum and tissue. In 61 cases HCV RNA was present at the same time in serum and liver tissue. Forty-four patients were men (72%) and 17 (28%) were women. Two peaks of age were observed: 1 in the 4th decade of life, the 2nd in the 7th. The 2 groups had different HCV genotypes. Patients with genotypes 1b (mean age 50.7 years), 2c (mean age 61.3 years), and a subgroup of coinfections (mean age 60 years) were older than patients with genotypes 1a (mean age 35.5 years), 3 (mean age 36 years), and a subgroup of coinfections (mean age 33 years). Patients with genotypes 1b, 2, or 2c and a subgroup of coinfections more frequently had a history of blood transfusion and or surgical intervention dating up to 49 years previously. Patients with HCV 1a, 3, and a subgroup of coinfections frequently admitted a period of intravenous drug abuse. Patients with advanced liver disease, i.e., severe fibrosis and cirrhosis, showed the same 2 peaks of incidence: in the 4th and 7th decades of life, the first group mainly comprising patients with HCV types 1a and 3, the second, patients with HCV types 1b and 2c. Both these groups shared a clinical history of a long-standing infection. Two profiles of patients emerged. The largest group was composed of elderly patients, infected by HCV genotypes 1b or 2c, with a history of blood transfusion and/or surgery, presenting an advanced stage of liver disease (namely, severe fibrosis or cirrhosis). The second group was composed of younger patients, mainly in the 4th decade of life, infected by HCV types 3 or 1a, often presenting with chronic hepatitis in the stage of severe fibrosis or cirrhosis. The latter could be the profile of HCV infection in the near future.

Abstract
PURPOSE To evaluate tolerance and efficacy of an open-label interferon-ribavirin treatment and their determinants in 62 HCV-HIV coinfected patients in routine followup. METHOD Patients received at least 6 and up to 12 months of combination interferon alpha-2b (peg or not) plus ribavirin. Determinants of therapeutic success were estimated by a multivariate logistic regression. RESULTS Five patients stopped the study, 4 were lost to follow-up, and 53 participated in the entire therapeutic protocol. Among these 53, the end-of-treatment results showed complete clearance of HCV-RNA in 17 (32%). A sustained virologic response (SVR) after 6 or 9 months was observed in 9 (17%) patients, 3 relapsed, and data were not available for 5. Genotype 3a (odds ratio [OR] = 14.4; confidence interval [CI] = 1.84-110.3) favored SVR and treatment with protease inhibitor (PI) therapeutic resistance (OR = 14.4; CI = 1.01-200); as well, a higher fibrosis score tended to increase resistance (p =.11). Adverse events were reported by 24/53 patients (45.3%). CONCLUSION HCV therapy associating interferon and ribavirin in HCV-HIV coinfected patients is well accepted even if tolerance is moderate. Treatment permitted SVR in at least 17% of the cases. This is likely when patients initiate treatment at the early fibrosis stage and are infected with genotype 3a. The potential interaction with PI therapy should be explored.

Abstract
The aims of this study were to assess the sociodemographic, epidemiological, clinical, and biological characteristics of French patients co-infected with human immunodeficiency virus-hepatitis C virus (HIV-HCV), as well as the management of their HCV infection. Data on 509 HIV-HCV co-infected patients, followed up at six French University Hospitals, were collected using a questionnaire. Student's t-test, Pearson's chi-square, Fisher's exact, and Fisher-Freeman-Halton's exact tests were used. The mean age of the patients was 38.3 years, and the male to female sex ratio 2.08; 88% of patients were born in Metropolitan France, and 20% were dependent on health benefits; 74% were intravenous drug users and 14% blood or blood product recipients. Forty-seven percent were in CDC classification stage A, 18% had a CD4+ count of <200, and 79% were undergoing current antiretroviral treatment. HCV RNA was positive in 84% (50% type 1, 13% untypable). Forty-four percent had normal alanine aminotransferase (ALT) levels, 24% alcohol consumption >15 g/day, and 51% had undergone liver biopsy (10% of which had cirrhosis). Histological grade was not related to ALT level or CD4+ count. Overall, 40% of patients had been treated for HCV infection. HCV treatment was significantly associated with performance of liver biopsy, histological grade, ALT level, CD4+ count, Centers for Disease Control (CDC) classification, but not with age or alcohol consumption. Rate of early response to treatment was fifty percent among patients treated with bitherapy. Eighty-nine percent of all patients with previous or current anti-HCV treatment had undergone liver biopsy. In conclusion, despite the difficulties in managing hepatitis C in HIV-infected patients, almost one-half of all patients in this study had received anti-HCV treatment.

Abstract
In the United States, an estimated 200,000 persons are infected with both hepatitis C virus (HCV) and human immunodeficiency virus (HIV). As the lives of HIV-infected persons have been prolonged by use of highly active antiretroviral therapy, liver disease has emerged as an important, and in some settings, the leading cause of morbidity and mortality. Human immunodeficiency virus infection appears to adversely affect all stages of hepatitis C infection, leading to increased viral persistence and accelerated progression of HCV-related liver disease. In turn, hepatitis C may affect the management of HIV infection, increasing the incidence of liver toxicity caused by antiretroviral medications. The medical management of hepatitis C in HIV-infected persons remains controversial, in part because of the complexity of both infections and potential drug interactions, but chiefly because there is so little published information. Nonetheless, the burden of liver disease is too high to delay management of HIV/HCV-coinfected persons while awaiting better data. Instead, the management of hepatitis C today must be based on data generated on persons without HIV and an understanding of both infections. Properly designed studies of therapy in HIV/HCV-coinfected persons are needed to help guide management of these patients in the future.
