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 AND AIMS Liver biopsy is standard for assessment of disease severity in patients with chronic HCV. However, associated risks have led to the development of simple non-invasive models. However, their utility in those with normal ALT is unknown. METHODS FIB-4 and APRI were calculated for patients with HIV-HCV coinfection undergoing biopsy. The performance of each model and AUROC for predicting significant fibrosis (Ishak 4-6) were determined for the entire cohort and stratified by elevated (≥60 U/l in men and ≥40 U/l in women) and normal ALT. RESULTS Two-hundred and ninety-five liver biopsies from 237 patients were included. Elevated ALT was observed in 55, and 15% had significant fibrosis. The AUROC curve for patients with elevated ALT was 0.8 for FIB-4 and 0.76 for APRI, compared with 0.90 for the FIB-4 and 0.85-0.95 for the APRI in those with normal ALT. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of FIB-4 were 1.0, 0.91, 0.50, and 1.0 for patients with normal ALT; the values were 0.67, 0.99, 0.67, and 0.99 for APRI. CONCLUSIONS Both FIB-4 and APRI are useful for highly accurate identification of those without advanced fibrosis. However, because they have poor positive predictive value, liver biopsy will continue to be used for assessment of patients with coinfection.

Abstract
BACKGROUND & AIMS Fibrosis progression might be accelerated in patients who are coinfected with human immunodeficiency virus (HIV) and HCV (HIV/HCV). However, no studies have directly compared fibrosis progression by paired liver biopsy between patients infected with HIV and HCV versus those infected with only HCV. METHODS Liver biopsy samples were collected from patients with HIV/HCV (n = 306) and those with HCV; biopsies from 59 without a sustained virologic response (SVR) or cirrhosis were matched with those from patients with only HCV (controls) for initial fibrosis stage, demographics, and HCV treatment. For HIV/HCV patients, categorical variables at baseline and the area under the curve of continuous variables per unit time were analyzed for associations with fibrosis progression. RESULTS Liver biopsies from HIV/HCV patients had more piecemeal necrosis than controls (P = .001) and increased lobular inflammation (P = .002); HIV/HCV patients also had shorter intervals between liver biopsies (4.7 vs 5.9 years, P < .0001). Between the first and second biopsies, fibrosis remained unchanged or progressed 1 or 2 units in 55%, 18%, and 18% of HIV/HCV patients, respectively, compared with 45%, 30%, and 9% of controls. The fibrosis progression rate was similar between HIV/HCV and control patients (0.12 ± 0.40 vs 0.091 ± 0.29 units/y; P = .72). In paired biopsies from 66 patients, including those with SVR, there were no associations between fibrosis progression and demographics; numbers of CD4+ T cells; levels of aspartate aminotransferase or alanine aminotransferase; use of highly active antiretroviral therapy; response to HCV therapy (no treatment, SVR, or non-response); baseline levels of FIB-4; or histologic features including inflammation, fibrosis, or steatosis. CONCLUSIONS On the basis of analysis of liver biopsy samples, fibrosis progression was similar between HIV/HCV-infected and HCV-infected patients; no clinical or laboratory parameters predicted disease progression.

Abstract
Liver fibrosis progress slowly in patients with chronic hepatitis C and persistently normal alanine aminotransferase (PNALT) compared to subjects with elevated aminotransferases. Differences in liver fibrosis according to human immunodeficiency virus (HIV) status in this population have not been examined. All patients with serum hepatitis C virus (HCV)-RNA and PNALT who underwent liver fibrosis assessment using elastometry since 2004 at three different European hospitals were evaluated. Patients previously treated with interferon were excluded. PNALT was defined as ALT below the upper limit of normality in at least three consecutive determinations within the last 12 months. Fibrosis stage was defined as mild (Metavir F0-F1) if stiffness < or =7.1 kPa; moderate (F2) if 7.2-9.4 kPa; severe (F3) if 9.5-14 kPa, and cirrhosis (F4) if >14 kPa. A total of 449 HIV-negative and 133 HIV-positive patients were evaluated. HIV-negative patients were older (mean age 51.8 vs 43.5 years) and more frequently females (63%vs 37%) than the HIV counterparts. Mean serum HCV-RNA was similar in both the groups (5.9 vs 5.8 log IU/mL). Overall, 78.8% of the HIV patients were on HAART and their mean CD4 count was 525 (+/-278) cells/microL. In HIV-negatives, liver fibrosis was mild in 84.6%; moderate in 8.7%, severe in 3.3% and cirrhosis was found in 3.3%. In HIV patients, these figures were 70.7%, 18.8%, 6%, and 4.5%, respectively. In the multivariate logistic regression analysis, older age (odds ratio or OR: 1.04; 95% confidence interval or CI: 1.02-1.07; P < 0.001) and being HIV+ (OR: 2.6; 95% CI: 1.21-5.85; P < 0.01) were associated with severe liver fibrosis or cirrhosis (F3-F4). Thus, severe liver fibrosis and cirrhosis are seen in 6.6% of the HCV-monoinfected and in 10.5% of HCV-HIV co-infected patients with PNALT. Some degree of liver fibrosis that justifies treatment is seen in 15% of the HCV-monoinfected but doubles to nearly 30% in HIV-HCV co-infected patients with PNALT.

Abstract
BACKGROUND Insulin resistance (IR), the major feature of the metabolic syndrome, is also common in patients with chronic HCV infection. Liver fibrosis and steatosis are known potential outcome of chronic hepatitis B or C infection. Studies have shown that HIV positive individuals co-infected with HCV have more rapid live disease progression than those with HIV alone. Few data have reported the influence of IR on steatosis and fibrosis in the context of HIV-HCV coinfection. AIM To test the association among insulin resistance (IR), liver fibrosis and liver steatosis in HIV-HCV and HCV-infected patients. PATIENTS AND METHODS A total of 170 HIV-HCV-infected patients matched by age, gender and genotype with 170 HCV mono-infected patients were included. Patients were considered to be IR when the homeostasis model assessment of IR >2. Significant fibrosis was considered if METAVIR >or=F2 and significant steatosis if >or=10%. RESULTS Insulin resistance was independently associated in HCV patients with fibrosis [odds ratio (OR) = 2.04 (95% CI 1.02-4)], a body mass index (BMI) >25 kg/m(2) [OR = 3.33 (1.47-7.69)] and steatosis [OR = 3.33 (1.67-6.67)]. Fibrosis >or=F2 was associated in HCV patients with high liver activity grade (>or=A2) [OR = 8.33 (3.85-16.67)], male gender [OR = 3.03 (1.33-7.14)] and IR [OR = 2.44 (1.15-5)]. In HIV-HCV patients, >or=A2 [OR = 5.56 (1.64-20)] was associated with fibrosis. Steatosis >or=10% was associated in HCV patients with IR [OR = 3.13 (1.59-6.25) and >or=F2 (OR = 2.22 (1.15-4.17)]. In HIV-HCV, a BMI >25 kg/m(2) [OR = 3.85 (1.64-9.10)], >or=A2 [OR = 2.16 (1.02-4.55); P = 0.044] and nucleoside reverse transcriptase inhibitor [OR = 3.61 (1.19-10.96); P = 0.023] were independently associated with significant liver steatosis. CONCLUSIONS Insulin resistance is associated with liver fibrosis and steatosis in HCV mono-infected, but not in HIV-HCV co-infected patients. Significant liver fibrosis is associated with IR independent of liver steatosis only in HCV mono-infected patients.

Abstract
PURPOSE The purpose of this study was to review the current management of hepatitis C virus (HCV) in persons coinfected with HIV. DATA SOURCES Comprehensive review of current scientific literature derived from electronic databases, article bibliographies, and conference abstracts. CONCLUSIONS HCV treatment is feasible in the individual coinfected with HIV; however, therapy is complex and requires intensive monitoring and support to achieve the outcome of viral eradication. New strategies to improve HCV treatment rates, adherence to therapy, and virological response rates are needed in this patient population. IMPLICATIONS FOR PRACTICE Nurse practitioners are crucial to the management of the HIV/HCV-coinfected patient. This patient population requires detailed clinical monitoring, education, side effect management, and strategies to improve adherence to therapy.

Abstract
BACKGROUND/AIMS To compare non-invasive biological liver fibrosis scores, as alternatives to liver biopsy, in HIV/HCV co-infected patients. METHODS Two hundred and seventy-two HIV/HCV patients, nai ve for HCV treatment, underwent liver biopsy [197 (72%) men, 39.9 years, fibrosis stage (Metavir) F1 (25%), F2 (40%), F3 (25%), F4 (10%), median CD4 486/mm(3) and median HIV viral load 3.5log. Fibrotest (FT), Hepascore (HS), Fibrometer (FM), SHASTA, APRI, Forns index, and Fib-4 were tested in order to differentiate patients with mild to moderate fibrosis (F2) and those with advanced fibrosis (F3). The AUROC and the rate of well-classified patients were compared to liver biopsy. RESULTS FT, HS, and FM were able to stage liver fibrosis in all patients with AUROCs of 0.78, 0.84 and 0.89 for the diagnosis of F2, respectively. The correlation coefficient indexes were 0.37, 0.46 and 0.48, respectively. The rates of well-classified patients were 62%, 68% and 71%, respectively. Fib-4, APRI and the Forn's index were only able to stage 37-61% of patients and showed lower accuracies. Using a combination of FT, HS and FM did not significantly increase the performance of each test. CONCLUSIONS In HIV/HCV co-infected patients, Fibrometer, Hepascore and Fibrotest outperformed other non-invasive liver fibrosis biomarkers for the prediction of significant liver fibrosis.

Abstract
Background Non-invasive liver fibrosis scores have been proposed as alternatives to liver biopsy (LB) in hepatitis C virus (HCV)-infected patients. Here, we aimed to assess the effect of antiviral treatment on non-invasive serological markers of liver fibrosis in HIV–HCV-coinfected patients. Methods We included 114 HIV–HCV-coinfected patients with LBs performed before and 6 months after the end of treatment (week 72; W72). Fibrotest, the Forn's index, age-platelet ratio index, SHASTA, FIB-4, Hepascore and Fibrometer scores were assessed. There were 29 (25%) patients who achieved sustained virological response (SVR). Results At baseline (BL), all non-invasive fibrosis scores except the Forn's index did not show significantly lower values in SVR patients. At W72, all non-invasive scores, except Hepascore, showed a significant decrease in SVR patients ( P<0.01). There was a significant difference in fibrosis stages on LBs between BL and W72 in SVR and non-SVR patients. Conclusions In HIV–HCV-coinfected patients, HCV clearance is associated with a significant reduction in non-invasive fibrosis serological markers, which most likely reflect the histological improvement associated with SVR. If confirmed, such results will reinforce the reliability of these markers in the follow-up after HCV treatment.

Abstract
This study aimed to investigate whether HIV and HIV-related factors are associated with spontaneously resolved hepatitis C virus (HCV) infection and levels of hepatitis C viremia. Among 351 anti-HCV(+) injection drug users, with and without HIV infection, multivariate methods were used to evaluate whether HIV status and HIV viral load, CD4 T-cell count, and concurrent HIV antiretroviral therapy were associated with (1) spontaneously resolved HCV infection and (2) HCV RNA levels. In 186 HIV patients, decreased HCV resolution was independently associated with Black race and modestly associated with CD4 T-cell count <200 cells/ml. Among 310 patients with persistent HCV infection, higher HCV RNA levels were independently associated with HIV status but not with other HIV-related factors. HIV may be associated with persistent HCV infection in patients with low CD4 T-cell counts. Moreover, HIV is associated with increased HCV viral load, which may attenuate response to HCV antiviral treatment in coinfected patients.

Abstract
PURPOSE OF REVIEW Chronic hepatitis C is currently one of the leading causes of hospitalization and death in HIV+ persons. Treatment is particularly challenging in coinfected patients due to lower efficacy and more side effects. RECENT FINDINGS The combination of pegylated interferon plus ribavirin is the current treatment of choice. In the absence of contraindications, treatment should be provided with no restrictions up front (e.g., asking unnecessarily for a liver biopsy) and revisited at weeks 4 and 12. Treatment should only be continued in early virological responders. The use of standard ribavirin doses (1000-1200 mg/day) and for at least 12 months is crucial to maximize the effect of therapy. In patients with rapid virological response (undetectable viraemia at week 4), shorter periods of therapy (24 weeks) may be advisable for hepatitis C virus genotypes 2 and 3. Patients with low CD4 percentages should defer treatment and prioritize highly active antiretroviral therapy. Didanosine should never be co-administered with ribavirin due to potential life-threatening complications. When possible, zidovudine, stavudine and abacavir should be replaced by other agents having no deleterious interactions with ribavirin. SUMMARY The treatment of chronic hepatitis C has become a priority in hepatitis C virus/HIV-coinfected patients, and the best results are obtained by tailoring therapy to the individual patient's characteristics.

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 Previous studies of patients with hepatitis C virus (HCV) infection looking at the effect of human immunodeficiency virus (HIV) co-infection on biochemical parameters and HCV RNA level have shown conflicting results. Accurate characterization of the effect of HIV is important for evaluation and treatment of HCV in co-infected persons. METHODS We studied 315 HCV mono-infected and 75 HCV-HIV co-infected subjects to determine the effect of HIV on biochemical parameters and HCV RNA and to determine the predictors of elevated serum alanine aminotransferase (ALT) levels and HCV RNA levels. RESULTS The co-infected subjects were more likely to be African-American (55% vs 26%, P < 0.0005), have used injection drugs (68% vs 60%, P = 0.02), have detectable HCV RNA (84% vs 70.5%, P = 0.018), have HCV RNA levels >6 log10 IU/mL (60% vs 38%, P = 0.001), and have lower mean serum ALT levels (50.4 IU/mL vs 73.7 IU/mL, P = 0.006). In multivariable analyses, the following factors predicted an ALT level >50 IU/mL: log10 HCV RNA (OR, 1.15; 95% CI, 1.00 to 1.32); HIV co-infection (OR, 0.48; 95% CI, 0.25 to 0.89); and having ever been treated for HCV (OR, 1.92; 95% CI, 1.16 to 3.18). The only significant predictor of HCV RNA level >6 log10 IU/mL was HIV co-infection (OR, 2.75; 95% CI, 1.46 to 5.15). Significant predictors of having a detectable HCV RNA level were female sex (OR, 3.81; 95% CI, 1.18 to 12.25); HIV co-infection (2.45; 95% CI, 1.14 to 5.26); and ever being treated for HCV (OR, 1.96; 95% CI, 1.10 to 3.48). CONCLUSIONS HCV-HIV co-infected persons have higher HCV RNA levels but lower serum ALT levels than HCV mono-infected patients. Criteria for performing liver biopsy and treating HCV infection in co-infected patients may need to be revisited.

Abstract
HIV and hepatitis C virus (HCV) are global health concerns, and coinfection with these viruses is common due to shared routes of transmission. Mortality rates from AIDS and HIV-associated opportunistic infections have decreased since the institution of highly active antiretroviral therapy, but the incidence of liver-related mortality in coinfected patients has subsequently risen significantly. This increase in progression of liver disease and its subsequent increased mortality have spurred research into the optimization of evaluation and management of the HIV-HCV coinfected patient.

Abstract
HIV, hepatitis C virus, and hepatitis B virus are global health concerns. Due to shared routes of transmission, coinfection is common. The incidence of liver-related mortality in coinfected patients has risen significantly since the inception of highly active antiretroviral therapy, a treatment that has helped decreased mortality rates from AIDS and opportunistic infections. This trend has led to increased research into the evaluation and management of the coinfected patient. This article details the principles of successful management of this challenging patient population.

Abstract
Insulin resistance is associated with highly active antiretroviral therapy in HIV-infected patients, and the risk of developing insulin resistance is increased in hepatitis C virus (HCV)-infected patients. The aim of the present study was to determine whether hepatitis C virus infection constitutes an additional risk factor for insulin resistance or other prothrombotic conditions in HIV-HCV coinfected patients under highly active antiretroviral therapy. One hundred eighteen HIV-infected patients were studied: 50 who had no history of anti-HIV treatment and 68 who were receiving therapy with highly active antiretroviral treatment. The treatment-naive group consisted of 35 HCV-negative subjects and 15 HCV-positive ones. Within the treated group, 50 patients were HCV negative and 18 were HCV positive. For each patient, the lipid profile was determined and the following values measured: glucose, soluble P-selectin (as a marker of platelet activation), soluble thrombomodulin, von Willebrand factor and soluble vascular cell adhesion molecule-1 (as endothelial markers), and insulin resistance. No significant difference (p>0.05) for any variable was found among subjects with or without HCV coinfection in the treatment-naïve group. Among patients under highly active antiretroviral therapy, however, those with HCV coinfection showed higher values (p<0.05) for insulin resistance (homeostasis model assessment value: 2.65 vs. 1.79), glucose (93 vs. 86 mg/dl), endothelial markers (von Willebrand factor, 204 vs. 123%; soluble vascular cell adhesion molecule-1, 650 vs. 482 ng/ml), and platelet activation marker (soluble P-selectin, 78 vs. 51 ng/ml) in parallel with lower CD4+ cells counts (289 vs. 402 cells/mm3) and higher HIV-1 viral loads (305 vs. 50 copies/ml) compared to patients without HCV coinfection. Glucose, soluble P-selectin, and von Willebrand factor were independently related to HCV infection. The presence of HCV coinfection during HIV treatment was closely related to higher values of insulin resistance, to activated platelets, and to endothelial perturbation in parallel with lower CD4+ cell counts and higher HIV-1 viral loads compared to patients without HCV coinfection. On the basis of these results, it may be preferable to treat HCV infection prior to initiating treatment for HIV infection in HIV-HCV-coinfected patients.

Abstract
OBJECTIVES The aim of this study was to further explore the severity of liver disease and its predictors in a cohort of hepatitis C virus (HCV) infected patients, some of whom were coinfected with the human immunodeficiency virus (HIV). METHODS This is a retrospective, cross-sectional study of patients undergoing liver biopsy to stage HCV disease prior to consideration of anti-HCV therapy. RESULTS A total of 92 HIV-HCV coinfected and 372 HCV monoinfected patients were included. As might be expected, coinfected patients differed from monoinfected patients in a number of ways, including having lower body mass index (BMI), and lower alcohol intake. Liver disease was very similar between the two groups, with mean fibrosis score of 1.45 u for coinfected and 1.53 u for monoinfected (p = NS). Histological inflammation score dominated multivariate models of fibrosis when it was included in them. When only clinical predictors were used in multivariate models, BMI and type 2 diabetes had independent associations in monoinfected patients, whereas low CD4 count, current or nadir, was the only variable with an independent association in coinfected patients. CONCLUSIONS Coinfected patients do not have uniformly worse liver disease than monoinfected patients. Immune compromise plays an important role in liver disease in coinfected patients, and the role of other clinical factors in liver disease may differ between these two groups, as well.

Abstract
Liver biopsy remains the gold standard in the assessment of severity of liver disease. Noninvasive tests have gained popularity to predict histology in view of the associated risks of biopsy. However, many models include tests not readily available, and there are limited data from patients with HIV/hepatitis C virus (HCV) coinfection. We aimed to develop a model using routine tests to predict liver fibrosis in patients with HIV/HCV coinfection. A retrospective analysis of liver histology was performed in 832 patients. Liver fibrosis was assessed via Ishak score; patients were categorized as 0-1, 2-3, or 4-6 and were randomly assigned to training (n = 555) or validation (n = 277) sets. Multivariate logistic regression analysis revealed that platelet count (PLT), age, AST, and INR were significantly associated with fibrosis. Additional analysis revealed PLT, age, AST, and ALT as an alternative model. Based on this, a simple index (FIB-4) was developed: age ([yr] x AST [U/L]) / ((PLT [10(9)/L]) x (ALT [U/L])(1/2)). The AUROC of the index was 0.765 for differentiation between Ishak stage 0-3 and 4-6. At a cutoff of <1.45 in the validation set, the negative predictive value to exclude advanced fibrosis (stage 4-6) was 90% with a sensitivity of 70%. A cutoff of >3.25 had a positive predictive value of 65% and a specificity of 97%. Using these cutoffs, 87% of the 198 patients with FIB-4 values outside 1.45-3.25 would be correctly classified, and liver biopsy could be avoided in 71% of the validation group. In conclusion, noninvasive tests can accurately predict hepatic fibrosis and may reduce the need for liver biopsy in the majority of HIV/HCV-coinfected patients.

Abstract
BACKGROUND AND AIMS The significance of normal alanine aminotransferase (ALT) levels in patients with HIV/hepatitis C virus (HCV) coinfection is not well understood. METHODS We performed a cross-sectional retrospective analysis on consecutive HIV/HCV-coinfected patients (n = 89) who underwent a liver biopsy during a 2-year period. Similar data were also collected on HCV-monoinfected patients (n = 117). RESULTS Mean ALT levels and the percentage of patients with normal ALT (< or =40 U/L) levels were similar in HIV/HCV-coinfected (mean +/- SD, 81.7 +/- 56.1 U/L; 21%) and HCV-monoinfected patients (97.3 +/- 100.7 U/L; 18%; P = 0.19 and 0.54, respectively). Coinfected patients, however, had significantly advanced necroinflammation (P= 0.001) and fibrosis (P = 0.02) compared with monoinfected patients. The percentage of patients with advanced necroinflammation (grades 3 or 4) was lower in HCV-monoinfected patients with normal ALT levels compared with those with elevated ALT (5% vs 20%, respectively). In contrast, the percentage of coinfected patients with advanced necroinflammation was similar whether the patient had normal or elevated ALT levels (32% vs 37%, respectively). CONCLUSIONS In coinfected patients, normal ALT levels are not an indicator of mild necroinflammation and may not portend a more benign disease course.

Abstract
Hepatitis C virus (HCV) coinfection is common in patients infected with human immunodeficiency virus (HIV), because the viruses share common routes of transmission. With the marked increase in life expectancy of HIV-infected patients associated with the use of highly active antiretroviral therapy, HCV infection has become a significant cause of morbidity and mortality in coinfected patients. As a result, there has been increasing attention to adequate assessment of HCV infection during the last several years. Unlike liver enzymes and HCV RNA levels, which can fluctuate widely and do not correlate with the severity of disease, liver biopsy has become the cornerstone in the evaluation of chronic HCV infection. However, there remain important questions and controversies related to adequately determining the histological severity of liver disease and the role of liver biopsy in HIV-HCV-coinfected patients.

Abstract
In the era of antiretroviral therapy (ART), liver disease has emerged as an important cause of death among persons with human immunodeficiency virus (HIV)/hepatitis C virus (HCV) coinfection. The objective of this study was to estimate the burden of liver disease and evaluate determinants of liver fibrosis and necroinflammatory activity among HIV/HCV coinfected patients receiving ART. We studied 112 randomly selected and 98 referred HCV-infected patients undergoing care in the Johns Hopkins University HIV clinic. Liver disease was characterized clinically and histologically. Of the 210 individuals studied--64% of whom had received ART within 2 years of liver disease assessment--33% had no fibrosis (F0), and 26% had bridging fibrosis or cirrhosis (> or =F3). The median necroinflammatory activity score was 3 (range, 0-9 of 18). ART was not associated with fibrosis; however, significantly less hepatic necroinflammatory activity was observed among persons who had received highly active antiretroviral therapy longer (P = .02) and more effectively (defined by HIV RNA suppression; P < .01). Twelve percent of individuals had previous ART-associated liver enzyme elevations (grades 3-4), but liver fibrosis was not more severe if the liver enzyme elevation resolved. On the other hand, liver fibrosis was more severe in persons with persistent liver enzyme elevations (grades 1-4). In conclusion, despite widespread exposure to ART and documented instances of ART-related hepatitis, we found no evidence that ART caused serious histological liver disease. Recognition of bridging fibrosis and cirrhosis in some but not most patients underscores the importance of identifying and treating liver disease in HIV/HCV coinfected persons.

Abstract
HIV infection is believed to adversely affect the progression of hepatitis C virus (HCV)-related liver disease. However, information regarding HIV and HCV coinfection in the era of highly active antiretroviral therapy (HAART) is scarce. A cross-sectional study in 75 HCV/HIV-coinfected patients (most of them on HAART) and 75 HCV-monoinfected patients paired by age, sex, and date of liver biopsy analyzed the association of HIV infection with advanced liver fibrosis (Knodell fibrosis stages 3 + 4). The median CD4 cell count in HIV-coinfected patients was 546 cells/microl; 78.7% had an HIV-1 viral load <1000 copies/ml and 88% were on antiretroviral therapy. The percentage of patients harboring genotype 4 and with a higher HCV viral load was greater in the HIV-coinfected group. HCV/HIV-coinfected patients had more advanced liver fibrosis (Knodell fibrosis stages 3 + 4) than HCV-monoinfected patients (46.7% vs. 12%, p < 0.0001). In the univariate analysis, the factors associated with advanced liver disease were male sex (OR: 2.7, 95% CI: 1.05-7.1), history of injecting drug use (OR: 4.6, 95% CI: 2.0-10.2), HIV infection (OR: 6.4, 95% CI: 2.7-14.7), and previous exposure to therapy with protease inhibitors (OR: 3.0, 95% CI:1.4-6.3). In the multivariate analysis; only male sex (OR: 3.17, 95% CI: 1.152-8.773) and HIV infection (OR: 6.85, 95% CI: 2.93-16.005) were associated with advanced liver fibrosis. HIV infection is associated with advanced liver fibrosis. HIV/HCV-coinfected individuals on HAART are at risk of developing end-stage liver disease despite virological success and immunological reconstitution.

Abstract
OBJECTIVES To describe changes in the proportions of patients admitted to hospital and the duration of admission during the month of March between 1995 and 2003 and to describe the factors related to admission for 9802 patients from EuroSIDA, a pan-European, observational cohort study. METHODS Generalized estimating equations were used to determine changes over time in the proportion of patients admitted and the median duration of admission. Logistic regression was used to determine factors related to admission in March 1995, March 1998 and March 2001. RESULTS The proportion of patients admitted during March declined from 7.4% in 1995 to 2.6% in 2003. After adjustment, the estimated reduction in the proportion of patients admitted was 5.5% per year [95% confidence interval (CI) 2.5-8.5%; P=0.0004], a 26% reduction. The median duration of hospital admission declined by 58% from 12 days in 1995 [interquartile range (IQR) 5-19 days] to 5 days in 2003 (IQR 3-12 days), a significant decline of 0.7 days per year after adjustment (95% CI 0.5-0.9 days; P=0.031). Patients with a lower CD4 lymphocyte count, and with an AIDS diagnosis made within the 3 months prior to March, all had increased odds of admission during March 1995, 1998 or 2001. In March 2001, patients whose treatment regimen was changed as a consequence of toxicities had increased odds of admission [odds ratio (OR) 2.34; 95% CI 1.26-4.37; P=0.0074]. In addition, patients who were hepatitis C virus-positive during March 2001 (OR 1.66; 95% CI 1.02-2.68; P=0.041) had increased odds of admission. CONCLUSIONS There has been a considerable decline in both the proportion of patients admitted to hospital and the median duration of the stay. Patients with hepatitis C had increased odds of admission, but there was little evidence of an increase in admissions among patients taking highly active antiretroviral therapy (HAART) associated with serious adverse events, although longer follow up is required.

Abstract
Hepatitis C virus (HCV) infection is frequent in human immunodeficiency virus (HIV)-infected patients. It is known to have an aggressive course in significantly immunosuppressed patients, and cirrhosis C has become one of the main causes of mortality in HIV-HCV coinfected patients since the improvement of antiretroviral therapy. The reasons for this severe fibrotic evolution are unclear. This prospective study compared chronic HCV lesions, liver immunocompetent cells, fibrosis and liver HCV loads in 2 cohorts of naive patients referred for HCV treatment: 33 HIV-HCV coinfected patients with CD4 >250/microL and 33 HCV-infected patients matched for the main risk factors of fibrosis. Fibrosis, particularly perisinusoidal fibrosis, was more marked in the coinfected patients. This occurred in the absence of a significant difference in disease activity. The number of CD3+ cells in the liver was higher in the HIV-HCV patients than in the HCV patients. Conversely, the number of liver CD4+ cells was lower in HIV-HCV patients than in HCV patients. The numbers of CD8+ and CD68+ cells were similar in the 2 groups. Finally, liver HCV load, assessed by immunostaining and reverse-transcription polymerase chain reaction, was similar in the 2 groups. We conclude that in the population of HIV-HCV coinfected patients with low-level immunosuppression referred for HCV treatment, fibrosis is worse than in HCV patients and the proportion of CD4+ lymphocytes among CD3+ cells is markedly decreased in the liver, whereas intrahepatic viral load is similar. Our data confirm the need to treat such patients against HCV, and suggest that HIV infection could favor fibrosis via the modulation of the intrahepatic immune response.

Abstract
Hepatitis C virus (HCV) coinfection is common among individuals with HIV, and the progression of liver disease is accelerated in coinfected individuals compared with those with HCV alone. HCV coinfection also can decrease tolerability of highly active antiretroviral therapy. Additionally, the presence of HCV appears to increase morbidity and mortality in these individuals, and as such the management of both HCV and HIV in coinfected individuals requires careful consideration. Although coinfected patients should be considered for HCV therapy, the limited information to date indicates a lower rate of virologic response with current HCV therapies. Moreover, interactions between HCV and HIV antiviral medications may occur and potentially affect treatment efficacy. Thus, the decision to undertake HCV treatment must be individualized.

Abstract
We review the evaluation and treatment of patients with drug addictions complicated by other acute or chronic diseases from the perspective of the hospital setting. The spectrum of drug addiction's complications is broad and in many instances it is predetermined by the abuse substance and its administration route. Some complications of intravenous drug addiction have dramatically decreased in the last few years as a result of a better knowledge of hygienic customs and after the implementation of some health interventions such as the provision of sterile injectable devices. Two highly prevalent infections --HIV/AIDS and hepatitis C-- remain from the period in which most HIV infections owed to the intravenous use of heroin. Of note, these two infections largely account for the survival and quality of life of those who quit their addiction. On the other hand, it is still common the hospitalization of patients with both alcohol dependence and intercurrent diseases in whom their drug addiction may pass unnoticed. Other common situations include the treatment of acute patients with cocaine addiction and psychiatric comorbidity, patients under methadone therapy and, in general, all those cases in which, in emergency, ordinary hospital wards and specialized units, a wide differential diagnosis is raised when there is a coexistence of signs and symptoms common to an addiction, infection and/or intoxication. An integral vision of drug addiction and its complications, as well as the clinical evaluation of all health problems, is fundamental for the prognosis and treatment of these patients.

Abstract
Strategies for the diagnosis and treatment of chronic hepatitis C continue to evolve. Liver biopsy is now used selectively rather than routinely, and the combination peginterferon plus ribavirin is the treatment of choice for the majority of patients.

Abstract
BACKGROUND Highly active antiretroviral therapy (HAART) has improved the prognosis of HIV infection. However, replication of hepatitis C virus (HCV) is not inhibited by HAART, and treatment-related hepatotoxicity is common. To clarify the effect of HAART in HIV/HCV-coinfected patients, we studied liver-related mortality and overall mortality in 285 patients who were regularly treated during the period 1990-2002 at our department. METHODS Survival was analysed retrospectively by Kaplan-Meier and Cox's regression analyses after patients (81% haemophiliacs) had been stratified into three groups according to their antiretroviral therapy (HAART n=93, available after 1995; treatment exclusively with nucleoside analogues n=55, available after 1992; or no treatment, n=137). FINDINGS Liver-related mortality rates were 0.45, 0.69, and 1.70 per 100 person-years in the HAART, antiretroviral-treatment, and untreated groups. Kaplan-Meier analysis of liver-related mortality confirmed the significant survival benefit in patients with antiretroviral therapy (p=0.018), and regression analysis identified HAART (odds ratio 0.106 [95% CI 0.020-0.564]), antiretroviral treatment (0.283 [0.103-0.780]), CD4-positive T-cell count (0.746 [0.641-0.868] per 0.05x10(9) cells/L), serum cholinesterase (0.962 [0.938-0.986] per 100 U/L), and age (1.065 [1.027-1.105] per year) as independent predictors of liver-related survival. Severe drug-related hepatotoxicity was seen in five patients treated with nucleoside analogues alone and 13 treated with HAART. No patient died from drug-related hepatotoxicity. INTERPRETATION In addition to improved overall survival, antiretroviral therapy significantly reduced long-term liver-related mortality in our patients. This survival benefit seems to outweigh by far the associated risks of severe hepatotoxicity.

Abstract
With highly active antiretroviral therapy (HAART), HIV-infected patients can now live longer and healthier lives, and other comorbid diseases, such as chronic hepatitis C, have emerged as a significant health concern. Coinfection with the hepatitis C virus (HCV) may limit life expectancy because it can lead to serious liver disease including decompensated liver cirrhosis and hepatocellular carcinoma. HCV-induced fibrosis progresses faster in HIV/HCV-coinfected persons, although HAART may be able to decrease this disease acceleration. Combination therapy for HCV with interferon and ribavirin can achieve a sustained viral response, although at a lower rate than in HCV-monoinfected patients. Combination treatment with pegylated interferon and ribavirin will probably emerge as the next HCV therapy of choice for HIV/HCV-coinfected patients. HCV combination therapy is generally safe, but serious adverse reactions, like lactic acidosis, may occur. Cytopenia may present a problem leading to dose reductions, but the role of growth factors is under study. All HIV/HCV-coinfected patients should be evaluated for therapy against the hepatitis C virus. A sustained viral load will probably lead to regression of liver disease, and even interferon-based treatment without viral clearance may slow down progression of liver disease. HIV/HCV-coinfected patients who have progressed to end-stage liver disease have few therapeutic options other than palliative care, since liver transplants are generally unavailable. The mortality post-transplant may be higher than in HCV-monoinfected patients. We are entering an era where safe and effective HCV therapy is being defined for HIV/HCV-coinfected patients, and all eligible patients should be offered treatment.
