Predictive plasma biomarkers of long-term increase in hepatic steatosis index after HCV eradication in HIV/HCV-coinfected patients. Biomed Pharmacother 2023; 164:114913. [PMID: 37216704 DOI: 10.1016/j.biopha.2023.114913] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 05/17/2023] [Accepted: 05/18/2023] [Indexed: 05/24/2023] Open
Abstract
Hepatic steatosis is a common condition found in the liver of hepatitis C virus (HCV)-infected patients, contributing to more severe forms of liver disease. In addition, the human immunodeficiency virus (HIV) may accelerate this process. Alternatively, several immune checkpoint proteins have been reported to be upregulated and correlated with disease progression during HCV and HIV infections. In steatosis, a detrimental immune system activation has been established; however, the role of the immune checkpoints has not been addressed so far. Thus, this study aimed to evaluate the association between plasma immune checkpoint proteins at baseline (before antiviral therapy) with hepatic steatosis index (HSI) increase at the end of follow-up (∼ five years after sustained virologic response (SVR)). We performed a multicenter retrospective study in 62 patients coinfected with HIV/HCV who started antiviral therapy. Immune checkpoint proteins were analyzed at baseline using a Luminex 200TM analyzer. The statistical association analysis was carried out using Generalized Linear Models (GLM) and Partial Least Squares Discriminant Analysis (PLS-DA). Fifty-three percent of the patients showed HSI increase from baseline to the end of follow-up. Higher immune checkpoint protein levels of BTLA, CD137(4-1BB), CD80, GITR, LAG-3, and PD-L1 before HCV therapy were associated with a long-term increase in HSI after successful HCV therapy, suggesting a potential predictive role for early detection of progression towards steatosis in HIV/HCV-coinfected patients.

Hepatology 2020; 71:1182-1197.

Abstract
BACKGROUND AND AIMS Human immunodeficiency virus (HIV)-hepatitis C virus (HCV)-coinfected patients are at high risk of metabolic complications and liver-related events, which are both associated with hepatic steatosis and its progressive form, nonalcoholic steatohepatitis, a known risk factor for mortality. The fatty liver index (FLI), a noninvasive steatosis biomarker, has recently drawn attention for its clinical prognostic value, although its capacity to predict mortality risk in HIV-HCV-coinfected patients has never been investigated. Using a Cox proportional hazards model for mortality from all causes, with data from the French National Agency for Research on Aids and Viral Hepatitis CO13 HEPAVIH cohort (983 patients, 4,432 visits), we tested whether elevated FLI (≥60) was associated with all-cause mortality. APPROACH AND RESULTS After multiple adjustment, individuals with FLI ≥ 60 had almost double the risk of all-cause mortality (adjusted hazard ratio [95% confidence interval], 1.91 [1.17-3.12], P = 0.009), independently of the following factors: HCV cure (0.21 [0.07-0.61], P = 0.004), advanced fibrosis (1.77 [1.00-3.14], P = 0.05), history of hepatocellular carcinoma and/or liver transplantation (7.74 [3.82-15.69], P < 10-3 ), history of indirect clinical signs of cirrhosis (2.80 [1.22-6.41], P = 0.015), and HIV Centers for Disease Control and Prevention clinical stage C (2.88 [1.74-4.79], P < 10-3 ). CONCLUSIONS An elevated FLI (≥60) is a risk factor for all-cause mortality in HIV-HCV-coinfected patients independently of liver fibrosis and HCV cure. In the present era of nearly 100% HCV cure rates thanks to direct-acting antivirals, these findings encourage the more systematic use of noninvasive steatosis biomarkers to help identify coinfected patients with higher mortality risk.

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

Abstract
Drug-induced liver injury (DILI) due to the use of prescription and non-prescription medication by HIV-positive and HIV-negative patients is one of the main causes of acute liver failure and transplantation in Western countries and, although rare, has to be considered a serious problem because of its unforeseeable nature and possibly fatal course. Drug-induced steatosis (DIS) and steatohepatitis (DISH) are infrequent but well-documented types of DILI. Although a number of commonly used drugs are associated with steatosis, it is not always easy to identify them as causative agents because of the weak temporal relationship between the administration of the drug and the clinical event, the lack of a confirmatory re-challenge, and the high prevalence of non-alcoholic fatty liver disease (NAFLD) in the general population, which often makes it difficult to make a differential diagnosis of DIS and DISH. The scenario is even more complex in HIV-positive patients not only because of the underlying disease, but also because the various anti-retroviral regimens have different effects on liver steatosis. Given the high prevalence of liver steatosis in HIV-positive patients and the increasing use of drugs associated with a potential steatotic risk, the identification of clinical signs suggesting liver damage should help to avoid the possible misdiagnosis of "primary" NAFLD in a patient with DIS or DISH. This review will therefore initially concentrate on the current diagnostic criteria for DIS/DISH and their differential diagnosis from NAFLD. Subsequently, it will consider the different clinical manifestations of iatrogenic liver steatosis in detail, with specific reference to HIV-positive patients. Finally, the last part of the review will be dedicated to the possible effects of liver steatosis on the bioavailability of antiretroviral and other drugs.

Abstract
Liver disease is a leading cause of morbidity and mortality among people with HIV, and in this era of safer and more effective hepatitis C therapy, non-alcoholic fatty liver disease (NAFLD) could soon emerge as the most common liver disease in this population. NAFLD is common among patients with HIV, and might be more likely to progress to non-alcoholic steatohepatitis (NASH) and NAFLD-related fibrosis or cirrhosis in these patients than in individuals without HIV. Several mechanisms of NAFLD pathogenesis are postulated to explain the disease severity in patients with HIV; these mechanisms include the influence of the gut microbiome, and also metabolic, genetic, and immunological factors. Although treatment strategies are currently based on modification of NAFLD risk factors, many new drugs are now in clinical trials, including trials specifically in patients with HIV. Thus, the identification and risk-stratification of patients with HIV and NAFLD are becoming increasingly important for accurately counselling of these patients regarding their prognosis and for establishing the most appropriate disease-altering therapy.

Abstract
Visceral and hepatic adiposities have been associated with both cardiovascular and liver disease and are of concern in HIV-infected persons in the modern era of combination antiretroviral therapy (ART). The development of therapeutic targets to reduce visceral and hepatic adiposities in HIV-infected persons has been slow, because of early reports that attributed the excess adiposity to specific antiretroviral drugs. Visceral adiposity was initially thought to occur as part of a protease inhibitor-induced "HIV-associated lipodystrophy syndrome." Subsequent studies show that visceral adiposity is likely a result of effective ART, recovery of health, and the normal aging process. Visceral adiposity is an established risk factor for hepatic adiposity. Identifying drug targets for non-alcoholic fatty liver disease is under active investigation. The present review summarizes the recent literature on the pathogenesis of visceral and hepatic adiposities in HIV-infected persons, current therapeutic strategies, and novel interventions in HIV-infected and uninfected persons.

Abstract
BACKGROUND AND AIM Previous studies have indicated that neck circumference is a valuable predictor for obesity and metabolic syndrome, but little evidence is available for fatty liver disease. We examined the association of neck circumference with fatty liver disease and evaluated its predictive value in Chinese adults. METHODS This cross-sectional study comprised 4053 participants (1617 women and 2436 men, aged 20-88) recruited from the Health Examination Center in Guangzhou, China between May 2009 and April 2010. Anthropometric measurements were taken, abdominal ultrasonography was conducted and blood biochemical parameters were measured. Covariance, logistic regression and receiver operating characteristic curve analyses were employed. RESULTS The mean neck circumference was greater in subjects with fatty liver disease than those without the disease in both women and men after adjusting for age (P<0.001). Logistic regression analysis showed that the age-adjusted ORs (95% CI) of fatty liver disease for quartile 4 (vs. quartile 1) of neck circumference were 7.70 (4.95-11.99) for women and 12.42 (9.22-16.74) for men. After further adjusting for other anthropometric indices, both individually and combined, the corresponding ORs remained significant (all P-trends<0.05) but were attenuated to 1.94-2.53 for women and 1.45-2.08 for men. An additive interaction existed between neck circumference and the other anthropometric measures (all P<0.05). A high neck circumference value was associated with a much greater prevalence of fatty liver disease in participants with both high and normal BMI, waist circumference and waist-to-hip ratio values. CONCLUSIONS Neck circumference was an independent predictor for fatty liver disease and provided an additional contribution when applied with other anthropometric measures.

Abstract
Human immunodeficiency virus (HIV), Hepatitis B (HBV) and Hepatitis C (HCV) are blood-borne viruses with potentially shared routes of transmission. In high-income settings, the impact of antiretroviral therapy (ART) on survival has unmasked chronic liver disease from viral hepatitis B or hepatitis C as a leading cause of morbidity and mortality in individuals with HIV infection. It is now feared that progressive liver disease may threaten the success of ART programmes in developing countries, where HCV or HBV testing and monitoring are not yet systematic among HIV-infected patients and ART use is generally blind to these co-infections. We set out to review recent data from Sub-Saharan Africa, in order to build a detailed and up-to-date picture of the epidemiology and emerging impact of HBV and HCV coinfection in countries at the heart of the HIV pandemic. There is a preponderance of HIV/HBV coinfection compared to HIV/HCV in this region, and significant caveats exist regarding the accuracy of published HCV seroprevalence surveys. Morbidity and mortality of coinfection is significant, and may be further enhanced in African populations due to the influence of host, viral and environmental factors. Careful scrutiny of the coinfection problem is vital to inform an approach to directing resources, planning public health initiatives, providing clinical care, and guiding future research.

Abstract
Aim To evaluate changes in liver histology in patients with human immunodeficiency virus/hepatitis C virus coinfection non-responders to a suboptimal Interferon + Ribavirine regimen. Materials and methods We investigated 49 patients with two sequential liver biopsies: 18 were non-responders to Interferon + Ribavirine treatment (Group hepatitis C virus Rx) administered after the 1st liver biopsy who underwent a 2nd liver biopsy after a median period of 3.92 year and 31 were patients who remained untreated for hepatitis C virus disease (Group hepatitis C virus untreated) after the 1st liver biopsy because of refusal and underwent a 2nd liver biopsy after a median period of 5.05-years. Most patients in both groups were under highly active antiretroviral therapy. At the time of 1st liver biopsy similar degrees of necro-inflammation, fibrosis and steatosis were observed in both groups. Changes in liver lesions between 1st and 2nd liver biopsys were adjusted for different intervals between liver biopsys by a mathematic formula. Results Liver fibrosis did not change in 88.9% of patients in Group hepatitis C virus Rx and in 77.4% in Group hepatitis C virus untreated. A marked deterioration in liver fibrosis was observed in 5 (16%) patients in Group hepatitis C virus untreated and in none in Group hepatitis C virus treated. Necro-inflammation and steatosis remained substantially unchanged in both groups. Conclusion Liver histology remained substantially unchanged in human immunodeficiency virus/hepatitis C virus patients non-responder to anti-hepatitis C virus therapy over 4 years observation, suggesting an effective anti-hepatitis C virus early treatment for all hepatitis C virus/human immunodeficiency virus coinfected patients who can reasonably tolerate therapy.

Abstract
BACKGROUND AND AIMS Abnormal liver enzymes (LEs) are common in those infected with human immunodeficiency virus (HIV). Histologic data on those with abnormal LE without viral hepatitis are lacking. METHODS HIV-positive subjects without hepatitis C virus, hepatitis B virus, alcohol abuse, and diabetes mellitus with more than 1 abnormal LE, defined as 1.25 ULN in aspartate aminotransferase, alanine aminotransferase, or alkaline phosphatase, over 6 months were included. Subjects underwent a 2-hour oral glucose tolerance test, fasting lipids, insulin and glucose for insulin resistance (IR) by homeostasis model assessment for insulin resistance (HOMA-IR) and dual-energy X-ray absorptiometry for fat distribution. Biopsies were read blindly to clinical data, and scored by Ishak histologic activity index for inflammation and fibrosis and NAFLD activity score. RESULTS Fourteen patients underwent biopsy. All were on highly active antiretroviral therapy with undetectable HIV RNA and mean CD4 614. The histologic activity index scores for inflammation and fibrosis were 3.43(1.4) and 1.71(1.26), respectively, and 2 patients had advanced fibrosis (bridging fibrosis/cirrhosis). The majority (65%) of patients had steatosis: grade 1: 21%, grade 2: 28%, and grade 3: 14%. Hepatocyte ballooning was seen in 7 (40%) but nonalcoholic steatohepatitis (NASH) was diagnosed only in 4 (26%). NAFLD activity score of all biopsies of 3.07 (2.2; range, 0 to 5). HOMA-IR was higher in those with compared with those without steatosis (3.52 vs. 1.91; P = 0.11) and highest in those with NASH (4.89). Using multivariate logistic regression, only increased γ-glutamyl transpeptidase (P = 0.0009) predicted steatosis whereas HOMA-IR (P = 0.0046) predicted NASH. CONCLUSIONS Although steatosis is common in HIV patients with abnormal LE without diabetes mellitus, alcohol, or viral hepatitis coinfection, NASH was observed in only 26%. The only clinical or laboratory feature associated with biopsy proven steatosis and NASH were γ-glutamyl transpeptidase and a calculated measure of insulin resistance, respectively. Further studies are needed in this population to determine the long-term clinical significance.

Abstract
UNLABELLED Hepatic steatosis (HS) is frequent in human immunodeficiency virus (HIV)- and hepatitis C virus (HCV)-coinfected patients. Antiretroviral therapy (ART) and metabolic alterations could induce HS. However, a protective effect of ART has been reported in a paired biopsy study. Thus, our aim was to examine the changes and predictors of HS progression among HIV/HCV-coinfected patients with sequential biopsies. We also evaluated the rates of steatohepatitis and factors associated thereof. HIV-infected patients with detectable serum HCV RNA, who underwent two biopsies, separated at least by 1 year, were included in this retrospective study. HS progression was defined as increase in one or more HS grades. The median (interquartile range) time between biopsies was 3.3 (2.0-5.2) years. Among 146 individuals, HS at baseline was observed in 86 (60%) patients and in 113 (77%) in the follow-up biopsy (P < 0.001). Progression of HS was observed in 60 (40%) patients. HS regressed in 11 (8%) patients. Factors associated with HS progression were changes in fasting plasma glucose (FPG) between biopsies (per 10 mg/dL increase; odds ratio [OR] [95% confidence interval; CI] = 1.4 [1.04-1.8]; P = 0.024) and cumulative use of dideoxynucleoside analogs (per year; OR [95% CI] = 1.5 [1.2-1.8]; P = 0.001). Persistent steatohepatitis or progression to steatohepatitis between biopsies was observed in 27 (18%) patients. Persistence of or progression to steatohepatitis was associated with progression ≥ 1 fibrosis stages between biopsies (OR [95% CI] = 2.4 [1.01-5.7]; P = 0.047). CONCLUSIONS HS progresses frequently and regression is rarely observed in HIV/HCV-coinfected patients, including in those on ART. Cumulative exposure to dideoxynucleoside analogs and increases in FPG are related with HS progression. Stetatohepatitis is frequently observed in these patients and is linked to fibrosis progression.

Abstract
Chronic hepatitis C is an independent risk factor for severe drug hepatotoxicity. Successful treatment of chronic hepatitis C may modulate drug hepatotoxicity, as it is associated with a decline in hepatic enzyme release and halts fibrosis progression in HIV/HCV-coinfected patients. The aim of this study was to determine biological and/or clinical determinants of alanine aminotransferase and/or aspartate aminotransferase elevation (>five-fold above the upper limit of normal in patients with normal baseline levels or >3.5-fold increase from baseline in those with increased baseline levels) in a large prospective cohort of HIV/HCV-coinfected patients on HAART who had previously been treated for HCV infection. Median follow-up exceeded five years. Cox proportional hazards models were used. At baseline, 248 patients had been receiving antiretroviral therapy for a mean of 6.3 (± 3.2) years. Seventy-one patients (29%) had a sustained HCV viral response (SVR). During follow-up, 66 patients (26.6%) received a second course of HCV therapy and 29 (44%) of them had an SVR. Severe transaminitis occurred in 64 patients (26%). In multivariate analysis, no SVR (HR 33.33, 95% CI 4.54-222, P = 0.001) and stavudine-based therapy (HR 2.11, 95% CI 1.12-3.99, P = 0.018) remained significantly associated with severe transaminitis. A SVR to anti-HCV therapy is thus associated with a markedly reduced risk of severe transaminitis during antiretroviral therapy. Treatment of HCV infection should therefore be a priority in HIV-coinfected patients. Stavudine is associated with an increased risk of severe transaminitis.

Abstract
Background Liver fibrosis in human immunodeficiency virus (HIV)-infected individuals is mostly attributable to co-infection with hepatitis B or C. The impact of other risk factors, including prolonged exposure to combined antiretroviral therapy (cART) is poorly understood. Our aim was to determine the prevalence of liver fibrosis and associated risk factors in HIV-infected individuals based on non-invasive fibrosis assessment using transient elastography (TE) and serum biomarkers (Fibrotest [FT]). Methods In 202 consecutive HIV-infected individuals (159 men; mean age 47 ± 9 years; 35 with hepatitis-C-virus [HCV] co-infection), TE and FT were performed. Repeat TE examinations were conducted 1 and 2 years after study inclusion. Results Significant liver fibrosis was present in 16% and 29% of patients, respectively, when assessed by TE (≥ 7.1 kPa) and FT (> 0.48). A combination of TE and FT predicted significant fibrosis in 8% of all patients (31% in HIV/HCV co-infected and 3% in HIV mono-infected individuals). Chronic ALT, AST and γ-GT elevation was present in 29%, 20% and 51% of all cART-exposed patients and in 19%, 8% and 45.5% of HIV mono-infected individuals. Overall, factors independently associated with significant fibrosis as assessed by TE (OR, 95% CI) were co-infection with HCV (7.29, 1.95-27.34), chronic AST (6.58, 1.30-33.25) and γ-GT (5.17, 1.56-17.08) elevation and time on dideoxynucleoside therapy (1.01, 1.00-1.02). In 68 HIV mono-infected individuals who had repeat TE examinations, TE values did not differ significantly during a median follow-up time of 24 months (median intra-patient changes at last TE examination relative to baseline: -0.2 kPa, p = 0.20). Conclusions Chronic elevation of liver enzymes was observed in up to 45.5% of HIV mono-infected patients on cART. However, only a small subset had significant fibrosis as predicted by TE and FT. There was no evidence for fibrosis progression during follow-up TE examinations.

Abstract
Liver disease in human immunodeficiency virus (HIV)-infected individuals encompasses the spectrum from abnormal liver function tests, liver decompensation, with and without evidence of cirrhosis on biopsy, to non-alcoholic liver disease and its more severe form, non-alcoholic steatohepatitis and hepatocellular cancer. HIV can infect multiple cells in the liver, leading to enhanced intrahepatic apoptosis, activation and fibrosis. HIV can also alter gastro-intestinal tract permeability, leading to increased levels of circulating lipopolysaccharide that may have an impact on liver function. This review focuses on recent changes in the epidemiology, pathogenesis and clinical presentation of liver disease in HIV-infected patients, in the absence of co-infection with hepatitis B virus or hepatitis C virus, with a specific focus on issues relevant to low and middle income countries.

Abstract
PURPOSE OF REVIEW Highly active antiretroviral therapy (HAART)-related hepatotoxicity, a relevant side effect in HIV/hepatitis C virus (HCV) co-infected patients, has evolved over time. Antiretroviral therapy might have a positive effect on the liver of HIV/HCV co-infected patients, but data are conflicting. RECENT FINDINGS HIV treatments have evolved and we have currently a drug armamentarium with a good liver safety profile. Most of the current first-line HAART regimens recommended by guidelines fit well to HIV/HCV co-infected patients. There are now multiple retrospective studies that suggest a possible benefit of HIV control and protection of CD4 cell counts to the liver of HIV/HCV co-infected patients. However, data are conflicting at times. This factor along with the methodological limitations of these studies prevent us from drawing definitive conclusions. Even assuming a positive effect, HAART does not appear to fully correct the adverse effect of HIV infection on HCV-related outcomes. In the era of HCV direct antiviral agents, the timing of HIV and HCV therapies has to be individualized in HIV/HCV co-infected patients given the variety of scenarios. SUMMARY With current HIV drug armamentarium it is possible to construct HAART regimens with optimal liver safety profile for HCV co-infected patients. The possible positive effect of HAART on the HCV-infected liver should not distract from the main intervention, which is HCV eradication with specific treatment.

Abstract
Liver damage may result from multiple factors in HIV-infected patients. The availability of reliable noninvasive tools to measure liver fibrosis has permitted the screening of large patient populations. Cross-sectional study of all consecutive HIV outpatients who underwent examination by transient elastometry (FibroScan) at one HIV reference clinic during 2007. Advanced liver fibrosis (ALF) was defined as hepatic stiffness >9.5 kilopascals, which corresponds to Metavir stages F3-F4 in the liver biopsy. A total of 681 consecutive HIV-infected patients (64% injecting drug users; mean age 43; 78% male; 98% on antiretroviral therapy) had at least one valid FibroScan evaluation. ALF was diagnosed in 215 (32%) of them. In the univariate analysis, ALF was significantly associated with older age, low CD4 counts, chronic hepatitis C, past alcohol abuse, elevated ALT, high triglycerides, low cholesterol, high homeostasis model assessment (HOMA) index and exposure to didanosine and/or stavudine. In a multivariate model (OR, 95% CI), chronic hepatitis C (2.83, 1.57-5.08), past alcohol abuse (2.26, 1.37-3.74), exposure to didanosine and/or stavudine (1.85, 1.14-3.01), high HOMA index (1.25, 1.04-1.51), older age (1.09, 1.05-1.14) and elevated ALT (1.04, 1.03-1.06) remained as independently associated with ALF. Therefore, in addition to chronic hepatitis C and alcohol abuse, insulin resistance and/or exposure to dideoxy-nucleosides may contribute to ALF in HIV-infected patients.

Abstract
Highly active antiretroviral therapy (HAART)-related hepatotoxicity complicates the management of patients infected with human immunodeficiency virus (HIV), increases medical costs, alters the prescription patterns, and affects the guideline recommendations. Among the clinical consequences derived from HAART-related liver toxicity, hypersensitivity reactions and lactic acidosis are recognized as acute events with potential to evolve into fatal cases, whereas there seems to be other syndromes not as well characterized but of equal concern as possible long-term liver complications. Belonging to the latter category of syndrome, HAART-related nonalcoholic steatohepatitis, liver fibrosis, portal hypertension, and nodular regenerative hyperplasia are discussed in this review. Updated information on liver toxicity of current antiretroviral drugs, including the most recently licensed, is provided. Management and prevention of liver toxicity among HIV-infected patients treated with HAART are reviewed as well.

Abstract
UNLABELLED Hepatic steatosis (HS) is frequent in patients with hepatitis C virus (HCV) infection, occurring in 40%-80%, associating with metabolic and virus-related factors, namely, genotype 3 and viral load. Human immunodeficiency virus (HIV) infection and antiretroviral treatment seem to be risk factors for HS. Several studies addressed this issue in coinfected patients, with discrepant results. A meta-analysis was performed on the HS risk factors in coinfected patients. Eligible studies were identified through structured keywords including coinfection, HCV, HIV, and steatosis in relevant databases including PubMed. Pooled odds ratios (ORs) and confidence limits (CIs) were obtained with the random-effects model and the DerSimonian-Laird method. Twelve studies, including 1,989 coinfected patients, were selected. Twenty percent were infected with HCV genotype 3. The overall prevalence of HS was 50.8% (23%-72%). Four studies also included 1,540 HCV monoinfected patients, not showing an increased risk for HS in coinfected patients (OR 1.61, 95% CI 0.84-3.10, P = 0.151). In coinfected patients, HS was associated with higher body mass index (OR 1.13, 95% CI 1.07-1.19, P < 0.001), diabetes mellitus (OR 2.32, 95% CI 1.32-4.07, P = 0.003), elevated alanine aminotransferase levels (OR 1.28, 95% CI 1.02-1.61, P = 0.035), necroinflammatory activity (OR 1.72, 95% CI 1.11-2.67, P = 0.016), and fibrosis (OR 1.67, 95% CI 1.20-2.34, P = 0.003). No associations were found between HS and gender, other metabolic factors (dyslipidemia, glucose, metabolic syndrome), HCV-related factors (genotype, viral load), or HIV-related factors (viral load, CD4 count, antiretroviral therapy, and class of medication). CONCLUSION In coinfected patients, HS does not seem to be more frequent than in HCV monoinfected patients and is mostly associated with metabolic factors, such as increased weight, diabetes mellitus, and more severe liver disease. The fact that no associations with HCV factors were found may be due to the small percentage of genotype 3-infected patients.

Abstract
Steatosis is observed in around 25 to 70% of HIV-infected subjects. Steatosis is multifactorial. Steatosis was mainly related to denutrition and opportunistic infections at the Aids era then to nucleosidic analogues and mitochondrial cytopathies. Today, it is mainly associated with HAART- related lipodystrophy, and other classical causes (hyperlipidemia, diabetes, HCV infection) leading to insulin resistance. In the ANRS HC 02 RIBAVIC trial, in 395 co-infected HIV-HCV patients, steatosis was observed in 241 patients (61%). Among them, 38% had a grade I steatosis (less than 30% of fatty hepatocytes), 16% had a grade II steatosis (30 to 70% of hepatocytes) et 7% a grade III (more than 70% of hepatocytes). In multivariate analysis, factors independently associated with steatosis were genotype 3, Metavir fibrosis score, body mass index, HCV viral load and ferritinemia. Lipodystrophy and antiretroviral treatment were rarely associated with steatosis in the ANRS HC 02 RIBAVIC and APRICOT trials. In these trials, steatosis worsened the fibrosis progression but did not impact on the rate of sustained virological response. Finally, steatosis significantly decreases in patients with sustained virological response.

Abstract
Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatosis (NASH) are common conditions in the setting of HIV infection, especially if HCV coinfection or metabolic syndrome's features are present. The factors that contribute to the progression of NAFLD to NASH and fibrosis are not completely known and the role of antiretroviral therapy is especially controversial. Although the natural history of NASH in the setting of HIV infection is unknown, it may emerge as one of the leading causes of liver disease over the long term in these patients. Liver biopsy is still the gold standard for the diagnosis of NASH. Indeed, although non-invasive techniques are promising tools for the diagnosis of NAFLD, they do not assess liver damage. There is no specific therapy for NASH in HIV infection, as the role of glitazones has not been evaluated in these patients.

Abstract
BACKGROUND/AIMS To evaluate the possible influence of baseline insulin resistance in sustained virological response. METHODS One hundred and fifty-five consecutive individuals from a multicentric cohort of HIV/HCV co-infected patients who underwent therapy with pegylated interferon plus ribavirin were included. The main outcome variable was sustained virological response, defined as undetectable plasma HCV RNA at week 24 after the end of the therapy. Insulin resistance was determined using the HOMA method. RESULTS Sustained virological response was achieved in 55 (36%) patients. Forty-two (38%) patients with a HOMA lower than 4 developed sustained virological response vs 13 (29%) of those with a HOMA above 4 (p=0.27). Analyses restricted to patients harbouring genotype 1 or 4 showed similar rates of sustained virological response among patients with a HOMA below and above 4 [19 (27%) vs 7 (24%); p=0.8]. In the multivariate analysis, genotype 3 [AOR 9.26; 95% CI 3.03-28.30; p<0.0001], a baseline HCV viral load below 600.000IU/mL [AOR 2.97; 95% CI 1.03-8.57; p=0.04] and baseline LDL cholesterol above 100mg/dL [AOR 6.62; 95% CI 1.97-22.19; p=0.002] were independently associated with sustained virological response. CONCLUSIONS Insulin resistance is not a relevant predictor of sustained virological response to pegylated interferon plus ribavirin in HIV/HCV co-infected patients.

Abstract
An increasing number of people are chronically infected with HIV and HCV, and/or HBV owing to shared routes of transmission. With the advent of HAART, liver disease secondary to hepatitis co-infections has emerged as a leading cause of morbidity and mortality in HIV-infected persons. There is increasing need to manage dual infection, but treatment is complicated by co-morbidities, overlapping toxicities, drug activities and resistance. A model of treatment that builds on the lessons learned from the treatment of HIV has evolved to maximize success of treating dual infections. This review will address current strategies for the management of HIV in the setting of HCV and HBV co-infection and discuss future treatment directions and challenges.

Abstract
OBJECTIVES Metabolic profiles correlate with hepatitis C virus (HCV) infection and are known to be predictors of virologic responses in chronic hepatitis C patients on interferon-based treatment. However, little is known about the differential association of lipid profiles with hepatitis C viral load between genotype 1 and 2 infections. The aim of this study was to evaluate the impact of lipid profiles on HCV RNA levels in patients with genotypes 1 and 2. METHODS A total of 531 chronic hepatitis C patients infected patients with HCV genotype 1 or 2 were consecutively enrolled. Univariate and multivariate approaches were used to estimate the associations between demographic, metabolic, and viral variables and HCV RNA levels. RESULTS Higher serum triglyceride, total cholesterol, and low-density lipoprotein levels correlated with higher HCV RNA levels. In multivariate analysis, genotype 1 infection, severe hepatitis activity, milder hepatic fibrosis, higher homeostasis model assessment of insulin resistance (HOMA-IR) index and triglyceride levels are associated with higher HCV viral loads (P<0.05). Subanalysis on patients with lower body mass index values showed higher HCV viral load was associated with higher HOMA-IR index and total cholesterol level (P<0.05). After stratification by HCV genotype, lipid profiles were significantly associated with HCV viral load in genotype 2 infection (P<0.05), but not genotype 1 infection. CONCLUSIONS A proportional relationship is found between serum lipid profiles and hepatitis C viral load in patients with genotype 2 infection; however, whether manipulation of lipid profiles would improve the response to current anti-HCV therapy is to be determined in further studies.

Abstract
Background Liver steatosis is a common finding in hepatitis C virus (HCV) infection and is associated with an increased progression of the disease. However, HCV genotype 3 steatosis presents a peculiar and virus-induced pathogenesis. We analysed the effect of HIV coinfection and antiretroviral therapy on hepatic steatosis and the effect of the steatosis on fibrosis in patients with or without HCV genotype 3 infection. Methods All consecutive HIV-infected and uninfected patients who had undergone a liver biopsy for evaluation of HCV infection at the Infectious Diseases Clinic (Modena, Italy) were included in this study. Primary outcomes were the presence or absence of steatosis or the presence of moderate or advanced fibrosis. Results A total of 284 patients were enrolled: 187 infected by HCV and 97 coinfected with HIV and HCV. In HCV genotype 3 patients, only HCV-related variables, such as plasma HCV RNA levels (odds ratio [OR] per log10 1.68, P<0.001) and estimated duration of HCV infection (OR per year 1.17, P=0.004) were associated with steatosis. In patients infected with other HCV genotypes, steatosis was associated with older age (OR per 5 years 1.47, P<0.001), with exposure to d-drugs in HIV–HCV-coinfected patients (OR 2.60, P=0.04) and specifically exposure to stavudine (OR 2.76 HIV–HCV-coinfected versus not HIV-infected patients, P=0.04). Steatosis was independently associated with bridging fibrosis only in patients infected by HCV genotype other than 3 (OR 4.03, P=0.01). Conclusions Hepatic steatosis, in both HCV-monoinfected and in HIV–HCV-coinfected patients, is strongly correlated with HCV genotype 3, probably through interactions between HCV virus and liver cells. HIV-related increase of steatosis in patients with HCV is probably related to anti-retroviral drugs, especially stavudine, in patients infected by HCV genotype other than 3.
