Abstract
Over the past 4 decades, the clinical care of people living with HIV (PLWH) evolved from treatment of acute opportunistic infections to the management of chronic, noncommunicable comorbidities. Concurrently, our understanding of adipose tissue function matured to acknowledge its important endocrine contributions to energy balance. PLWH experience changes in the mass and composition of adipose tissue depots before and after initiating antiretroviral therapy, including regional loss (lipoatrophy), gain (lipohypertrophy), or mixed lipodystrophy. These conditions may coexist with generalized obesity in PLWH and reflect disturbances of energy balance regulation caused by HIV persistence and antiretroviral therapy drugs. Adipocyte hypertrophy characterizes visceral and subcutaneous adipose tissue depot expansion, as well as ectopic lipid deposition that occurs diffusely in the liver, skeletal muscle, and heart. PLWH with excess visceral adipose tissue exhibit adipokine dysregulation coupled with increased insulin resistance, heightening their risk for cardiovascular disease above that of the HIV-negative population. However, conventional therapies are ineffective for the management of cardiometabolic risk in this patient population. Although the knowledge of complex cardiometabolic comorbidities in PLWH continues to expand, significant knowledge gaps remain. Ongoing studies aimed at understanding interorgan communication and energy balance provide insights into metabolic observations in PLWH and reveal potential therapeutic targets. Our review focuses on current knowledge and recent advances in HIV-associated adipose tissue dysfunction, highlights emerging adipokine paradigms, and describes critical mechanistic and clinical insights.

Comparison of the prevalence, severity, and risk factors for hepatic steatosis in HIV-infected and uninfected people. BMC Gastroenterol 2019; 19:52. [PMID: 30987601 PMCID: PMC6466708 DOI: 10.1186/s12876-019-0969-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2018] [Accepted: 03/28/2019] [Indexed: 12/26/2022] Open
Abstract
Background Hepatic steatosis is prevalent in Western countries, but few studies have evaluated whether the frequency and severity of steatosis are greater in the setting of HIV infection. We compared the prevalence and severity of hepatic steatosis between HIV-infected (HIV+) and uninfected persons and identified factors associated with greater steatosis severity within both groups. Methods We performed a cross-sectional study among participants without cardiovascular disease who participated in a substudy of the Veterans Aging Cohort Study. Hepatic steatosis was defined by noncontrast computed tomography (CT) liver-to-spleen (L/S) attenuation ratio < 1.0. Multivariable linear regression was used to: 1) evaluate the association between HIV infection and severity of hepatic steatosis, as measured by absolute liver attenuation, and 2) identify factors associated with greater severity of steatosis, by HIV status. Results Among 268 participants (median age, 55 years; 99% male; 79% black; 23% obese; 64% HIV+ [91% on antiretroviral therapy]), the overall prevalence of steatosis was 7.8% and was similar between HIV+ and uninfected individuals (13 [7.6%] versus 8 [8.2%], respectively; p = 0.85). Participants with HIV, the majority of whom received antiretroviral therapy, had a higher mean absolute liver attenuation (mean difference, 5.68 Hounsfield units; p < 0.001), correlating with lesser hepatic steatosis severity, compared to uninfected participants. After adjusting for covariates, only advanced hepatic fibrosis was associated with greater severity of steatosis in HIV+ persons (p = 0.03) and uninfected individuals (p < 0.001). Conclusions In this sample of participants without cardiovascular disease, the prevalence of hepatic steatosis by noncontrast abdominal CT was not different by HIV status. Increasing severity of steatosis was independently associated with advanced hepatic fibrosis in both groups.

Steatosis Rates by Liver Biopsy and Transient Elastography With Controlled Attenuation Parameter in Clinical Experience of Hepatitis C Virus (HCV) and Human Immunodeficiency Virus/HCV Coinfection in a Large US Hepatitis Clinic. Open Forum Infect Dis 2019; 6:ofz099. [PMID: 30968054 PMCID: PMC6451651 DOI: 10.1093/ofid/ofz099] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2018] [Revised: 02/12/2019] [Accepted: 02/25/2019] [Indexed: 12/21/2022] Open
Abstract
Background Steatosis contributes to liver fibrosis in hepatitis C virus (HCV) and human immunodeficiency virus (HIV)/HCV coinfection. Liver biopsy (LB) is the reference standard for grading steatosis and staging fibrosis, yet recent advances in noninvasive modalities have largely supplanted LB, which may limit recognition of steatosis. We evaluated steatosis rates by LB and transient elastography (TE) with controlled attenuation parameter (CAP) among HCV-infected and HIV/HCV-coinfected patients in a US clinic. Methods Patients with chronic HCV infection during pretreatment evaluation by LB (n = 421; December 2001 through May 2014) and TE with CAP (n = 1157; May 2016 through May 2017) were included. Fibrosis and steatosis rates by LB and TE with CAP were stratified by HCV versus HIV/HCV coinfection status. Results Steatosis was not reported in 26.1% of LBs. Moderate to severe steatosis (grade ≥S2) was detected more often with CAP than with LB (in 24.0% vs 11.4% of patients, respectively). Median CAP values were higher in patients with HCV monoinfection than in those with coinfection (230 vs 215.5 dB/m, respectively; P < .001). With TE, the rate of advanced fibrosis (values F3–F4) was higher in HCV monoinfection than in coinfection (25.9% vs 14.8%, respectively; P <.001). With both LB and TE, advanced fibrosis (F3–F4) was significantly associated with moderate to severe steatosis (S2–S3) in HCV monoinfection compared with HIV/HCV coinfection (33.3% vs 4.4%, respectively for LB [P = 0.003] and 36.0% vs 29.0% for TE [P = 0.008]). Conclusions In patients with chronic HCV undergoing liver fibrosis staging, steatosis was detected more often with CAP than LB, with median CAP values higher in HCV monoinfection than HIV/HCV coinfection. Steatosis severity may be increasing in the modern HCV treatment era.

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
BACKGROUND Little is known about the importance of liver fibrosis and fatty liver in HIV-monoinfected individuals without hepatitis virus co-infection, particularly among the Asian population. AIM To evaluate prevalence and risk factors for liver fibrosis and fatty liver in Asian HIV-monoinfected individuals. METHODS Eighty asymptomatic HIV-monoinfected individuals (tested negative for HBV/HCV) were compared with 160 matched HIV-uninfected healthy controls. Transient elastography and proton-magnetic resonance spectroscopy ((1) H-MRS) were performed to measure liver stiffness and hepatic steatosis respectively. Blood samples were analysed for metabolic profiles and markers of steatohepatitis (e.g. cytokeratin-18). RESULTS All HIV-infected individuals (mean ± s.d. age 54 ± 11 years, male 93%, Chinese 94%; diagnosis median duration 8 (IQR 4-13 years) were stable on anti-retrovirals (PI-based 58.7%, NNRTI-based 25.0% integrase-inhibitors 16.3%); diabetes, dyslipidaemia, and metabolic syndrome were common. Fatty liver disease was detected in 28.7%. There was significantly higher degree of liver stiffness [4.9 (IQR 4.1-6.2) kPa vs. 4.2 (IQR 3.6-5.0) kPa, P < 0.001], and greater proportions developed significant fibrosis (7.0 kPa, 14.3% vs. 3.1%, P = 0.001) and cirrhosis (10.3 kPa, 5.2% vs. 0.6%, P = 0.040) compared with controls. HIV infection was an independent risk factor for significant fibrosis (adjusted OR 4.00, 95% CI 1.29-12.41, P = 0.016). HIV-infected individuals with fatty liver had excessive liver stiffness and fibrosis. Two cases of asymptomatic hepatocellular carcinoma were detected. CONCLUSIONS HIV-monoinfected patients are at risk for liver fibrosis and cirrhosis. HIV-related mechanisms and fatty liver disease may play important roles. Screening and intervention to prevent severe outcomes should be considered.

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
This study analysed the impact of PNPLA3 variants on liver histology of 168 HIV/hepatitis C virus (HCV)-coinfected patients who were naïve for HCV treatment. A athologist unaware of the patients' condition graded liver fibrosis and necroinflammation (Ishak) and steatosis (Kleiner). Patients were tested for PNPLA3 variants and genotyped for the PNPLA3 rs738409 C to G variant underlying the I148M substitution. All were hepatitis B surface antigen negative and stated no alcohol abuse. The mean age was 40.6 (37.6-44.1) years, 72.6% were males, 42% had HCV genotype 3, 38.9% HCV genotype 1 and 79.2% were receiving highly active antiretroviral therapy. The 79 patients with the PNPLA3 p.148I/M or M/M variants more frequently showed severe steatosis (score 3-4) than the 89 with PNPLA3 p.148I/I (43% vs. 24.7%, p 0.001), whereas no difference was observed in the degree of necroinflammation or fibrosis. Compared with 112 patients with lower scores, 56 with severe steatosis showed higher body mass index (p 0.03), higher rate of HCV genotype 3 (55.6% vs. 35.2%, p 0.01), PNPLA3 p.148I/M or M/M (60.7% vs. 39.3%, p 0.01) and lower CD4(+) cells/mm(3) (514.00 (390.5-673.0) vs. 500.00 (399.0-627.0); p 0.002). At multivariate analysis, body mass index (p 0.01), HCV genotype 3 (p 0.006), CD4(+) cell count (p 0.005) and PNPLA3 p.148I/M or M/M variants (p 0.01) were found to be independent predictors of severe liver steatosis. The PNPLA3 p.148 I/M or M/M variants and CD4(+) cell count were the only independent predictors of severe steatosis in patients with HCV non-3 genotypes. This is the first study to show that among HIV/HCV-coinfected patients the PNPLA3 p.148I/M or M/M variant have substantially less impact on steatosis for those with HCV genotype 3 than non-genotype 3.

Abstract
There are an estimated 40 million HIV infected individuals worldwide, with chronic liver disease being the 2nd leading cause of mortality in this population. Elevated liver functions are commonly noted in HIV patients and the etiologies are varied. Viral hepatitis B and C, fatty liver and drug induced liver injury are more common. Treatment options for viral hepatitis C are rapidly evolving and are promising, but treatments are limited for the other conditions and is primarily supportive. Opportunistic infections of the liver are now uncommon. Irrespective of etiology, management requires referral to specialized centers and with due diligence mortality can be reduced.

Abstract
OBJECTIVES Human immunodeficiency virus (HIV) infection and antiretroviral therapy (ART) may increase the risk of fatty liver disease. We determined the prevalence of and risk factors for fatty liver by comparing HIV-infected men with HIV-uninfected men who have sex with men in the Multicenter AIDS Cohort Study (MACS). METHODS In 719 MACS participants who consumed less than three alcoholic drinks daily, fatty liver was defined as a liver-to-spleen attenuation ratio <1 on noncontrast computed tomography (CT). We genotyped single nucleotide polymorphisms in the patatin-like phospholipase domain-containing 3 (PNPLA3) gene and in other genes previously associated with nonalcoholic fatty liver disease. Risk factors for fatty liver were determined using multivariable logistic regression. RESULTS Among 254 HIV-uninfected men and 465 HIV-infected men, 56% were White with median age 53 years and median body mass index 25.8 kg/m(2). The vast majority of HIV-infected men (92%) were on ART, and 87% of the HIV-infected men were treated with a nucleoside reverse transcriptase inhibitor for a median duration of 8.5 years. Overall, 15% of the cohort had fatty liver, which was more common in the HIV-uninfected compared with the HIV-infected men (19 vs. 13%, P=0.02). In multivariable analysis, HIV infection was associated with a lower prevalence of fatty liver (odds ratio (OR)=0.44, P=0.002), whereas a higher prevalence of fatty liver was seen in participants with PNPLA3 (rs738409) non-CC genotype (OR=2.06, P=0.005), more abdominal visceral adipose tissue (OR=1.08 per 10 cm(2), P<0.001), and homeostatic model assessment of insulin resistance (HOMA-IR) ≥4.9 (OR=2.50, P=0.001). Among HIV-infected men, PNPLA3 (rs738409) non-CC genotype was associated with a higher prevalence of fatty liver (OR=3.30, P=0.001) and cumulative dideoxynucleoside exposure (OR=1.44 per 5 years, P=0.02). CONCLUSIONS CT-defined fatty liver is common among men at risk for HIV infection and is associated with greater visceral adiposity, HOMA-IR, and PNPLA3 (rs738409). Although treated HIV infection was associated with a lower prevalence of fatty liver, prolonged exposure to dideoxynucleoside analogs is associated with higher prevalence.

Abstract
: Insulin resistance is associated with nonresponse to hepatitis C virus (HCV) treatment. In this multicenter, single-arm pilot study, adult, HIV/HCV genotype 1-coinfected previous nonresponders to peginterferon/ribavirin (PegIFN/RBV) with homeostatic model assessment of insulin resistance >2.5 were treated with pioglitazone (PIO) for 24 weeks followed by PegIFN/RBV/PIO. Three of 19 subjects (15.8%) achieved undetectable HCV RNA at week 24 of PegIFN/RBV/PIO, which was not significantly different than the historical null rate of 10% (P = 0.29, lower limit of the exact 1-sided 90% confidence interval 5.9%). Over the 24 weeks of PIO monotherapy, alanine aminotransferase and aspartate aminotransferase declined significantly and correlated with improved metabolic parameters.

Abstract
BACKGROUND The combination of transient elastometry with a controlled attenuation parameter (CAP) is available to evaluate hepatic steatosis (HS) along with liver stiffness. AIMS To assess the concordance of CAP measurements between two independent observers in patients infected by HIV and/or hepatitis virus, as well as to determine the concordance of classification of the grade of HS using two cut-off values. MATERIALS AND METHODS In a cross-sectional prospective study, CAP-enabled transient elastometry acquisitions were performed by two independent observers in patients with HIV or hepatitis virus infection. The interobserver concordance between the CAP examinations was assessed using the intraclass correlation coefficient and the concordance in the classification of patients in the grades of HS was characterized using the κ index. RESULTS A total of 118 patients were included. Twenty (17%) patients were HIV monoinfected, 44 (37.3%) were hepatitis C virus monoinfected, and 52 (44%) had HIV/hepatitis C virus coinfection. The median (Q1-Q3) of the absolute difference of CAP values between the two observers was 20 (10-41) dB/m. The overall intraclass correlation coefficient was 0.84 (95% confidence interval: 0.77-0.88). The corresponding figures for liver stiffness measurements were 0.9 (0.4-2.6) kPa and 0.96 (95% confidence interval: 0.94-0.97). The κ indexes for the concordance of classification for the presence of HS, cut-off of 215 dB/m, and significant HS, cut-off of 252 dB/m, were 0.53 and 0.62, respectively. CONCLUSION The determination of HS by means of CAP in HIV and/or hepatitis virus infection represents an observer-independent and easily performable method. However, the use of cut-off values for the classification of patients is suboptimal.

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.

Absence of liver steatosis in HIV-HCV co-infected patients receiving regimens containing tenofovir or abacavir. Infection 2012; 41:425-9. [PMID: 23225268 DOI: 10.1007/s15010-012-0378-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2012] [Accepted: 11/24/2012] [Indexed: 12/31/2022]
Abstract
BACKGROUND In human immunodeficiency virus-hepatitis C virus (HIV-HCV) co-infected patients, steatosis has been independently associated with a number of antiretroviral drugs, including stavudine, especially in patients with non-3 HCV genotypes. We retrospectively investigated the presence of steatosis among HIV-HCV co-infected and HCV mono-infected patients, and the role of tenofovir disoproxil fumarate (TDF) or abacavir (ABC) in determining hepatic steatosis. METHODS Liver steatosis was retrospectively evaluated in all consecutive biopsies performed in the period 2000-2008 in HCV mono-infected and HIV-HCV co-infected patients. A steatosis rate of >5 % was considered to be significant, and a multivariate logistic analysis was performed to evaluate factors associated with steatosis. RESULTS In total, 393 HCV-infected patients underwent liver biopsy during the study period, of whom 205 (52.2 %) were co-infected with HIV. A steatosis rate of >5 % was diagnosed in 33.0 % of HCV mono-infected and in 47.8 % of HIV-HCV co-infected patients (P = 0.003). The rate of steatosis was higher in patients resuming antiretroviral therapy (54.7 %) than in naïve patients (33.3 %; P = 0.006). When the overall population was considered, steatosis was associated to HCV genotype 3 [odds ratio (OR) 4.53, 95 % confidence interval (CI) 2.71-7.58; P < 0.001]. In terms of the use of nucleos(t)ide drugs in HIV co-infected patients, multivariate analysis showed that only in patients with HCV genotypes other than genotype 3 was steatosis related to the use of stavudine (OR 5.38, 95 % CI 1.18-24.53; P = 0.03). The use of TDF (OR 1.07, 95 % CI 0.39-2.88; P = 0.898) or ABC (OR 0.592, 95 % CI 0.09-4.07; P = 0.594) was not associated with steatosis. CONCLUSION In HCV mono-infected and HIV-HCV co-infected patients, steatosis appears to be a virus-mediated effect of HCV genotype 3. In HIV patients infected with HCV genotypes other than genotype 3, the risk of developing steatosis was higher in those patients resuming antiretroviral regimens containing old drugs rather than the new antiretrovirals.

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
Background In HIV and hepatitis C virus (HCV) coinfected patients, the role of antiretroviral therapy (ART) on hepatic steatosis (HS) remains controversial. Methods HIV/HCV coinfected patients receiving ART and previously untreated for HCV who underwent a liver biopsy were included. Cumulative duration of exposure to each antiretroviral was recorded up to liver biopsy date. Logistic regression analyses evaluated factors associated with steatosis and its severity. Results 184 patients were included: median age 41years, 84% male, 89% Caucasian, 61% with a past history of intravenous drug use. HCV genotypes were 1 (55%), 2 (6%), 3 (26%), and 4 (13%). Median HCV-RNA was 6.18 log10 IU/ml. HIV-RNA was undetectable (<400 copies/ml) in 67% of patients. Median CD4 count was 321/mm3. All patients had been exposed to nucleoside reverse transcriptase inhibitors (median cumulative exposure 56months); 126 received protease inhibitors (23months), and 79 non-nucleoside reverse transcriptase inhibitors (16months). HS was observed in 102 patients (55%): 41% grade 1; 5% grade 2, and 9% grade 3. In multivariate analysis, HCV genotype 3 and HCV viral load were moderately associated with mild steatosis but strongly with grade 2-3 steatosis. After adjustment for the period of biopsy, no association was detected between HS and exposure to any antiretroviral class or drug, or duration of ART globally or comparing genotype 3 to others. Conclusions Among our ART-treated HIV-HCV cohort predominantly infected with genotype 1, 55% of patients had HS which was associated with HCV-related factors, but not ART class or duration of exposure.

Abstract
BACKGROUND AND AIMS To promote our understanding of the relative contribution of metabolic and viral factors, the independent predictors of fatty liver and insulin resistance (IR) were assessed by comparing patients with nonalcoholic fatty liver disease (NAFLD) to individuals with virus-associated fatty liver disease (VAFLD): human immunodeficiency virus (HIV)-VAFLD, hepatitis C virus (HCV)-VAFLD and HIV-HCV-VAFLD. METHODS One hundred eighty eight consecutive patients with viral infections (103 HIV, 85 patients with HCV genotype 1 infection: 45 mono-infected and 40 HIV/HCV co-infected) with or without steatosis and 126 NAFLD patients were analyzed. Steatosis was diagnosed by ultrasonography. To assess the odds ratio (OR) of steatosis and IR, HCV and NAFLD, respectively, were used as the reference values. IR was evaluated through homeostasis model (HOMA) and the metabolic syndrome (MetS) using standard criteria. RESULTS The prevalence of VAFLD was 47%. Multivariate logistic regression analysis was carried out using HCV as the reference. VAFLD was predicted by HIV, HIV/HCV, female gender, waist circumference (WC) and HOMA (OR = 3.99, 3.76, 2.80, 1.08 and 1.18). According to multiple linear regression using NAFLD as the reference, IR was predicted by HCV, HIV and HIV/HCV, WC, triglycerides (coefficient beta = 2.25, 0.99, 1.86, 0.08, 0.05, respectively). In linear models, for any given number of components of MetS, HCV and HCV/HIV-associated fatty liver disease had greater HOMA compared to NAFLD (p <0.001). CONCLUSIONS Whereas HIV confers a higher risk of steatosis, VAFLD is associated with higher IR than NAFLD and such an effect is specifically linked to HCV rather than to HIV infection.

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
PURPOSE OF REVIEW Antiretroviral drugs are associated with hepatotoxicity. Progress in our knowledge on the prevalence, contributory factors and mechanisms is reviewed. RECENT FINDINGS Liver toxicity is highly prevalent and a major cause of hospitalization among HIV-infected individuals. Liver steatosis is probably more frequent in the setting of hepatitis C virus coinfection but is also seen in noncoinfected patients. Among the individual drugs, severe liver toxicity is more strongly associated with nevirapine, and the mitochondrial toxicity of some nucleoside analogues. Mitochondrial toxicity can also induce or contribute to steatohepatitis, with dietary uridine supplementation as a possible strategy of prevention. Atazanavir inhibits UDP-glucuronosyltransferase, which in Gilberts' syndrome has been associated with breast cancer. A UDP-glucuronosyltransferase gene promoter variant predisposes to hyperbilirubinemia. Tipranavir induces elevated transaminases more frequently than boosted comparator protease inhibitors. CCR5 inhibitors may predispose to hepatotoxic events by causing an imbalance in the cytokine response. SUMMARY Hepatotoxicity is associated with all classes of antiretroviral agents and continues to contribute to hospitalization.

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
Clinical progression of chronic hepatitis C depends on several cofactors, which also have a negative affect on the rate of response to interferon-alpha-based therapy. Given the current worldwide prevalence of the metabolic syndrome, the impact of obesity and insulin resistance, and of their histopathological correlate, hepatic steatosis, on the natural history and management of chronic hepatitis C is undoubtedly very important. We will review some of the current knowledge on the clinical consequences of overweight/obesity, steatosis and insulin resistance on chronic hepatitis C, and discuss how this issue may be dealt with in clinical practice.

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
OBJECTIVE To describe the prevalence and factors associated with nonalcoholic fatty liver disease (NAFLD) among HIV-infected persons not infected with hepatitis C virus (HCV). DESIGN : A cross-sectional study among HIV-infected patients in a large HIV clinic. METHODS NAFLD was defined as steatosis among patients without viral hepatitis (B or C) coinfection or excessive alcohol use. The prevalence of NAFLD was identified by ultrasound examination evaluated by 2 radiologists blinded to the clinic information; liver biopsies were performed on a subset of the study population. Factors associated with NAFLD were evaluated by proportional odds logistic regression models. RESULTS Sixty-seven of 216 patients (31%) had NAFLD based on ultrasound evaluation. Among those with NAFLD, steatosis was graded as mild in 60%, moderate in 28%, and severe/marked in 12%. Factors associated with the degree of steatosis on ultrasound examination in the multivariate model included increased waist circumference [odds ratio (OR) 2.1 per 10 cm, P < 0.001], elevated triglyceride levels (OR 1.2 per 100 mg/dL, P = 0.03), and lower high-density lipoprotein levels (OR 0.7, per 10 mg/dL, P = 0.03). African Americans were less likely to have NAFLD compared with whites (14% vs. 35%), although this did not reach statistical significance (OR 0.4, P = 0.08). Similar associations were noted for the subset of patients diagnosed by liver biopsy. CD4 cell count, HIV viral load, duration of HIV infection, and antiretroviral medications were not independent risk factors associated with NAFLD after adjustment for dyslipidemia or waist circumference. CONCLUSIONS NAFLD was common among this cohort of HIV-infected HCV-seronegative patients. NAFLD was associated with a greater waist circumference, low high-density lipoprotein, and high triglyceride levels. Antiretroviral medications were not associated with NAFLD; prospective studies are needed to confirm this finding.

[PMID: 19096512 PMCID: PMC2593088 DOI: 10.1155/2009/373524] [Citation(s) in RCA: 15] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2008] [Accepted: 08/25/2008] [Indexed: 12/22/2022] Open
Abstract
Highly active antiretroviral therapy (HAART)-associated metabolic complications include lipoatrophy (loss of subcutaneous adipose tissue (SAT)) and insulin resistance. Thiazolidinediones are insulin-sensitizing antidiabetic agents which-as an untoward side effect in obese diabetic patients-increase SAT. Furthermore, troglitazone has improved lipoatrophy and glycemic control in non-HIV patients with various forms of lipodystrophy. These data have led to 14 clinical trials to examine whether thiazolidinediones could be useful in the treatment of HAART-associated metabolic complications. The results of these studies indicate very modest, if any, effect on lipoatrophic SAT, probably due to ongoing HAART negating the beneficial effect. The benefit might be more prominent in patients not taking thymidine analoges. Despite the poor effect on lipoatrophy, thiazolidin-ediones improved insulin sensitivity. However, especially rosiglitazone induced harmful effects on blood lipids. Current data do not provide evidence for the use of thiazolidinediones in the treatment of HAART-associated lipoatrophy, but treatment of lipoatrophy-associated diabetes may be warranted. The role of thiazolidinediones for novel indications, such as hepatosteatosis, should be studied in these patients.

Abstract
UNLABELLED Hepatitis C virus (HCV) is the most common blood-borne infection in developed countries and co-infection with the Human Immunodeficiency Virus (HIV) is frequent in individuals with history of injecting drug use (IDU).We aimed to analyze liver transaminases in HCV monoinfected and HCV/HIV co-infected patients to assess the effect of HIV infection on liver enzyme elevations.We studied 429 current IDUs admitted to substance abuse treatment (82.5% males). Serum samples for liver tests, HIV infection and viral hepatitis serologies were obtained at admission. RESULTS Median age was 30 years (IQR:27-34), median duration of IDU was 10 years (IQR:5-14), 52% of patients were HCV/HIV co-infected, 40.8% were HCV monoinfected, and 7.2% were HCV and HIV- seronegatives. Elevated AST was associated with male gender and lower CD8(+) cell count in the HCV monoinfected patients, and with age and lower cholesterol in the HCV/HIV coinfected subjects. ALT elevation was associated with younger age, higher body mass index and male gender in the monoinfected patients, and with higher CD4(+) cell counts and lower cholesterol in the co-infected group. Male sex was strongly associated with elevated ALT and AST transaminase in the monoinfected but not in dual-infected subjects.These data suggest that the effect of gender on liver enzymes may be lost in patients with HIV infection. The overall differences observed between groups regarding liver enzyme elevations are of clinical relevance in the management of IDUs with chronic hepatitis C.

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.

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.

BMC Res Notes 2008; 1:46.

Abstract
BACKGROUND AND AIMS Patients with HIV and hepatitis C virus (HCV) coinfection are at increased risk of developing hepatic steatosis. The aims of this study were to assess the prevalence of steatosis in a cohort with HIV-HCV coinfection, and to determine an association, if any, between steatosis, antiretroviral therapy (ART), and advanced hepatic fibrosis. PATIENTS AND METHODS HIV-HCV coinfected patients were retrospectively identified from the HIV clinic. ART was classified as none, nucleoside reverse transcriptase inhibitors (NRTIs) only, highly active antiretroviral therapy (HAART) only, and sequential therapy (initial NRTIs followed by HAART). Fibrosis stage and necroinflammation grade were assessed by the modified HAI (Ishak) scoring method. Steatosis was graded as 0-3. RESULTS Sixty patients were identified. The overall prevalence of hepatic steatosis was 58%. Those that received HAART only had a lower prevalence of steatosis (41%) compared to those on NRTIs only (70%) or sequential therapy (82%). Independent predictors of hepatic steatosis were absence of HAART only therapy, OR 2.9, p = 0.09, and presence of cirrhosis, OR 4.6, p = 0.044. Forty five percent of the patients had advanced fibrosis (fibrosis stage >/= 3). NI grade (OR 1.9, p = 0.030), and steatosis grade (OR 3.6, p = 0.045), were independent predictors of advanced fibrosis. CONCLUSION Hepatic steatosis is associated with more advanced hepatic fibrosis in the HIV-HCV coinfected population. HAART only therapy (rather than NRTIs only or sequential therapy) appears to be associated with a lower prevalence of hepatic steatosis. This may be one of the mechanisms by which HAART could attenuate hepatic fibrosis in such a cohort.

Abstract
BACKGROUND Abnormal liver enzymes (LFTs) are frequently seen in HIV patients. Because HCV and HBV overshadow other possible variables, little is known about the prevalence and predictive factors of abnormal LFTs in the absence of viral hepatitis. AIMS To determine the prevalence and factors associated with abnormal LFTs defined as >1.25 ULN. METHODS A retrospective analysis of HIV clinic patients was performed. Variables were determined at the time of abnormal LFTs or by history and included diabetes mellitus (DM), hypertension (HTN), dyslipidemia, HCV and HBV status, metabolic syndrome (MS), and HAART use (NRTI, NNRTI, and PI). RESULTS Patients without HCV/HBV (n = 679/1,208) were younger, Caucasian, had a BMI >30 and had dyslipidemia. The prevalences of elevated LFTs in those without HCV/HBV were AST 20%, ALT 15%, and ALP 43% compared to 64%, 46%, and 63% in those with HCV (all P < 0.0001), and 98% were mild-moderate (grade 1-2). While AST was highly correlated with ALT, neither was associated with increased ALP. In those without HCV/HBV, increased AST was associated with HTN, HIV RNA, and absence of PI use; increased ALT was associated with HTN, HIV RNA, CD4 < 200, MS, and absence of PI use, while increased ALP was associated with age, BMI, CD4%, DM, and NRTI use. CONCLUSIONS Mild-moderate increased liver enzymes are common in HIV patients without HCV/HBV and absence of PI use is independently associated with elevations in both AST and ALT, while features typical of hepatic steatosis (DM and BMI) are only associated with increased ALP.

Abstract
BACKGROUND/AIMS Hepatic steatosis is caused by the complex interaction of host and viral factors, such as metabolic syndrome (MS), alcoholism and HCV genotype, and in HIV-HCV co-infected patients, antiretroviral therapy may also play a role. A large population of patients from the AIDS Pegasys Ribavirin International Co-infection Trial (APRICOT) had paired liver biopsies interpreted and graded for steatosis along with lipid measurements and anthropometric data. METHODS We analyzed these patients to determine the prevalence of steatosis, baseline factors associated with steatosis, effect of steatosis in HCV therapy efficacy and the impact of anti-HCV treatment on steatosis. RESULTS A total of 65/283 (23%) patients with paired biopsies were positive for steatosis. Patients with steatosis were significantly more likely to have HCV genotype 3, bridging fibrosis/cirrhosis, higher HCV RNA levels, increased triglycerides and lower cholesterol levels. The only different body measurement was neck circumference which was greater in patients with steatosis and significantly decreased from baseline during the study. Hip circumference was predictive of steatosis at baseline. CONCLUSIONS Factors associated to the metabolic syndrome are important in co-infected patients. Treatment outcome affected steatosis in that viral eradication reduced steatosis in genotype 3 patients, but altogether steatosis did not affect efficacy of treatment in any genotype.

Abstract
UNLABELLED Hepatic steatosis has been reported in human immunodeficiency virus (HIV)/hepatitis C virus (HCV) coinfection. However, the features of steatohepatitis, including cytologic ballooning and pericellular fibrosis, its risk factors, and the impact on disease severity in such patients are unknown. To assess this, we prospectively reviewed liver histology in consecutive coinfected patients to define the prevalence and severity of the features of steatohepatitis, its risk factors, and its impact on the severity of liver disease. A total of 222 subjects (74% male, mean age 45, 78% African American, 90% genotype 1) were studied. The mean body mass index (BMI) was 26, and 18% had a BMI >30. The prevalence of risk factors for steatosis were: diabetes (31%), hypertension (15%), dyslipidemia (8%), metabolic syndrome (9%), and alcohol abuse (21%). Steatosis was present in 23% and steatohepatitis was present in 17%. The steatosis was mild (5%-33%) in 19%, and moderate to severe (>33%) in 4%. Cytologic ballooning and pericellular fibrosis were present in 30% and 13%, respectively. The mean Ishak score was 6.9, and 33% had bridging fibrosis or cirrhosis. Both steatosis and cytologic ballooning were associated with BMI, metabolic syndrome, and insulin resistance, and presence of either was strongly associated with advanced fibrosis (P < 0.0001). By multiple logistic regressions, the following associations were identified: increased BMI, diabetes, and genotype 3 with steatosis; diabetes with cytologic ballooning; and longer duration of infection with steatohepatitis. CONCLUSION Steatosis and steatohepatitis are present in 23% and 30%, respectively, of patients with HIV/HCV coinfection, and both are associated with an increased risk of having advanced fibrosis. Although we did identify genotype 3, increased BMI, and diabetes as risk factors, we found no independent association with antiretroviral therapy.

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 Significance of steatosis in HIV-HCV coinfection remains controversial. AIM To compare the prevalence and predictors of hepatic steatosis between HIV-HCV and HCV patients matched for steatosis known determinants. METHODS A total of 564 HCV-naive patients undergoing liver biopsy were studied: 137 with HIV-HCV coinfection and 427 with HCV monoinfection, among whom 137 were matched for age, gender, body mass index and HCV genotype. RESULTS Steatosis of any grade (67.1% vs. 41.6%, P < 0.0001), mixed steatosis (55.4% vs. 21.1%, P < 0.0001), severe histological activity (A2-A3: 78.1% vs. 55.5%, P < 0.0001) and severe fibrosis (F3-F4: 33.1% vs. 15.3%, P < 0.0001) were significantly more common in coinfected than in matched monoinfected patients. In multivariate analysis, steatosis was associated only with severe histological activity [odds ratio (OR): 3.1 (95% CI: 1.3-7.1)] in coinfected patients and with elevated body mass index [OR; 1.3 (1.1-1.5)], HCV genotype 3 [OR: 5.6 (2.3-13.9)], severe histological activity [OR: 3.1 (1.3-7.3)] and severe fibrosis [OR: 4.7 (1.3-17.3)] in monoinfected patients. CONCLUSIONS Steatosis is significantly more common and severe in HIV-HCV coinfected than in HCV monoinfected French patients, even after matching for body mass index and HCV genotype. Steatosis is associated only with severe histological activity in coinfected patients and with previously reported factors in monoinfected patients, thus suggesting different underlying mechanisms.

Abstract
In HIV/hepatitis C virus (HCV)-coinfected patients, it is recommended to repeat liver biopsy every 3 years when anti-HCV treatment is not indicated. We studied fibrosis progression in HIV/HCV-coinfected patients, who were not receiving anti-HCV treatment, on the basis of two successive liver biopsies. Thirty-two patients were retrospectively included. Twenty-six patients (79%) were on antiretroviral treatment at the first biopsy. The mean CD4 cell count was 470 +/- 283/mm(3). Three patients were staged F2 and the remainder F0/F1. The median interval between the two biopsies was 49 (24-80) months. At the second biopsy, the stage distribution was F0 0%, F1 41% (n = 13), F2 34% (n = 11), F3 19% (n = 6) and F4 6% (n = 2). The mean fibrosis progression rate (FPR) was 0.25 points/year. Nine patients (28%) were considered as rapid fibrosis progressors (progression by more than two points) and their FPR was 0.5 point/year; comparison of these subjects with the other 23 patients showed no relation between FPR and age, alcohol consumption, CD4+ cell count, HIV viral load, HCV genotype, aspartate aminotransferase or alanine aminotransferase. Analysis of the treatment received between the two liver biopsies did not find any correlation between liver FPR and a specific compound. Fifteen patients started anti-HCV therapy based on the second biopsy. Liver fibrosis in HIV/HCV-coinfected patients should be evaluated at least every 3 years, as nine of 32 (28%) of our patients progressed by at least two fibrosis points despite a high CD4+ cell count. The second biopsy showed that 15 patients (45%) qualified for anti-HCV therapy. Development of noninvasive methods of fibrosis evaluation should permit more frequent monitoring.

Abstract
BACKGROUND Hepatic steatosis is a common feature in liver biopsies from patients with chronic hepatitis C and is associated with fibrosis progression. Patients with HIV infection and hepatitis C virus (HCV) coinfection have more rapid progression of liver fibrosis than patients with HCV infection alone. The prevalence and factors associated with hepatic steatosis are not well defined in HCV-HIV-coinfected patients. METHODS Steatosis was assessed among 148 HCV-HIV-coinfected patients of the Aquitaine Cohort. Steatosis was graded as follows: none, mild (1%-10% of hepatocytes), moderate (11%-30%), severe (31%-60%), and massive (more than 60%). Epidemiologic, clinical, biologic, and therapeutic data were retrieved from the cohort database to investigate the risk factors. RESULTS Steatosis was present in 67% of patients (95% confidence interval [CI]: 59% to 74%) and was at least moderate in 30% (95% CI: 23% to 38%). Steatosis was macrovesicular or mixed (macro- and microvesicular) in 40.5% and 52.8% of patients, respectively. Necroinflammatory activity was the only factor independent of steatosis (adjusted odds ratio = 5.3, 95% CI: 1.6 to 17.9). When necroinflammatory activity was removed from the model, HCV genotype 3 and body mass index (BMI) were significantly associated with steatosis. CONCLUSIONS Liver inflammation, HCV genotype 3, and BMI are associated with steatosis, a common finding in HCV-HIV-coinfected patients.

Abstract
Human immunodeficiency virus/hepatitis C virus (HIV/HCV) co-infection has emerged as a leading cause of liver morbidity in the last two decades. Liver failure is also frequently a cause of death in HIV/HCV co-infected patients. Highly active antiretroviral treatment (HAART) has revolutionized the HIV treatment, leading to a significantly decreased morbidity, prolonged survival, and an overall better outcome of HIV infection. Hepatotoxicity associated with antiretroviral treatment, however, has been recognized as one of the serious complications of the treatment. The effects of HIV infection on the natural history and progression of HCV-associated chronic liver disease that had been well documented in the pre-HAART treatment era have been changing, and there are now many indications that HIV/HCV co-infection should be recognized as an evolving and a challenging disease entity.

Abstract
The evaluation of hepatic histology and treatment of hepatitis C virus (HCV)/HIV-coinfected patients is rapidly changing. HCV has become an important cause of mortality in HIV-infected patients. Consequently, assessment of liver histology in all coinfected patients is particularly important. The evaluation of hepatic histology is shifting from reliance on the liver biopsy toward noninvasive modalities. Additionally, the importance of HCV-associated morbidity and mortality in HIV-infected patients has prompted increasing numbers of these patients to be HCV treatment candidates. Prospective trials in coinfected patients have reported lower sustained virologic responses compared to HCV-monoinfected patients. Consequently, the numbers of coinfected nonresponders to pegylated interferon/ribavirin continues to increase. Because none of the presently available treatment modalities for pegylated interferon/ribavirin nonresponders are clearly efficacious, management decisions must be individualized. The options include, HCV-specific medications, maintenance therapy, the use of alternative interferon formulations, and observation. HCV-specific agents, particularly protease and polymerase inhibitors, show early promise in HCV-monoinfected individuals. Their use in coinfected patients, however, is likely to be delayed for several years, and they are likely to be used in combination with interferon. Low-dose pegylated interferon, administered in an attempt to slow fibrosis progression (maintenance therapy), is being evaluated in several large prospective trials in monoinfected and coinfected patients. Observation may be best for nonresponders with relatively mild hepatic histology. In summary, HCV treatment will likely follow the example forged by HIV. In the near future, combinations of different drugs will likely be used simultaneously to result in durable viral suppression.

Abstract
As persons with HIV live longer, chronic liver disease is increasingly important. Nonalcoholic fatty liver disease (NAFLD) is characterized by excess fat in hepatocytes in patients without significant alcohol use. It can progress from steatosis to nonalcoholic steatohepatitis (NASH) to cirrhosis. Visceral obesity and insulin resistance are integral to the pathogenesis of NAFLD. Patients with HIV are at greater risk of NAFLD due to antiretroviral therapy and viral hepatitis coinfection. Antiretroviral therapy can lead to patterns of injury that include steatosis and NASH. Coinfection with hepatitis C virus increases the risk of insulin resistance and hepatic steatosis, and co-existent features of NASH have also been reported. Histological-based, longitudinal studies are needed that address the interactions of NAFLD and HIV infection, the effects of antiretroviral therapy and hepatotropic virus coinfection, and inform better management strategies.

Abstract
BACKGROUND We conducted a study to determine the prevalence and factors associated with hepatic steatosis in human immunodeficiency virus (HIV)-seropositive patients with hepatitis C and to investigate whether steatosis is associated with liver fibrosis. METHODS Retrospective chart reviews were conducted in 4 hospitals that serve community-based and incarcerated HIV-infected patients who had undergone a liver biopsy for evaluation of hepatitis C virus (HCV) infection during the period of 2000-2003. Demographic characteristics and medication and laboratory data were collected from the time of the biopsy. A pathologist blinded to all clinical data evaluated the specimens. The primary outcome was presence or absence of steatosis. RESULTS Of 260 HIV-HCV-coinfected patients, 183 met inclusion criteria and had a biopsy specimen adequate for review. Steatosis was present in 69% of patients (graded as minimal in 31%, mild in 27%, moderate in 18%, and severe in 1%). Factors associated with steatosis included use of dideoxynucleoside analogues, such as didanosine and stavudine (odds ratio [OR], 4.63; 95% confidence interval [CI], 1.55-13.82). There was a trend toward presence of steatosis and use of other nucleoside analogues or infection with HCV genotype 3 (OR, 2.65 [95% CI, 0.95-7.41] and 3.38 [95% CI, 0.86-13.28], respectively). The presence of steatosis was associated with fibrosis (OR, 1.37; 95% CI, 1.03-1.81). CONCLUSIONS In this multiracial population of HIV-HCV-coinfected patients, steatosis was prevalent and was associated with severity of liver fibrosis. Use of nucleoside analogues (particularly didanosine and stavudine) and HCV genotype 3 infection were associated with hepatic steatosis. The development of steatosis is multifactorial in nature and may play a contributory role in the progression of liver disease in HIV-infected patients.

Abstract
BACKGROUND/AIMS Although steatosis is strongly associated with hepatitis C virus (HCV) infection, little is known about this finding in patients coinfected with human immunodeficiency virus (HIV) and HCV. The aims of the present study were to determine the prevalence and severity of steatosis in HIV/HCV coinfected patients. METHODS Consecutive patients undergoing liver biopsy were prospectively identified and were interviewed to obtain detailed demographic and clinical data. Steatosis was scored according to the percentage of hepatocytes involved: 0 (none), 1 (<33%), 2 (33-66%), or 3 (>66%); fibrosis was scored on a scale from 0 to 4. RESULTS A total of 708 patients were enrolled, including 154 with HIV/HCV coinfection and 554 with HCV monoinfection. Steatosis of any grade (72.1 vs. 52.0%, P<0.001), grade 2/3 steatosis (48.1 vs. 20.2%, P<0.001), and stage 3/4 fibrosis (43.5 vs. 30.0%, P=0.002) were significantly more common in coinfected patients. Compared to HCV monoinfected subjects, HIV/HCV coinfection was associated with a significantly increased odds of steatosis of any grade (OR=3.21; 95% CI, 1.84-5.60) and grade 2/3 steatosis (OR=5.63; 95% CI, 3.05-10.36) after adjusting for potential confounding variables. Among coinfected patients, the fibrosis progression rate increased in a linear fashion with the grade of steatosis. CONCLUSIONS Steatosis is more common and more severe in HIV/HCV coinfected patients than in those with HCV monoinfection.

Abstract
PURPOSE OF REVIEW Publications concerning liver histopathology in fatty liver disease and chronic hepatitis C, iron and copper overload, and liver transplantation from the past year have been surveyed to highlight useful concepts and diagnostic information. RECENT FINDINGS Two microscopic forms of pediatric nonalcoholic steatohepatitis have been described: type 1 in which hepatocyte ballooning and/or pericellular fibrosis accompany the steatosis; and type 2 which has portal tract inflammation and/or fibrosis as the salient accompanying feature. In chronic hepatitis C, the ductular reaction appears to be a major factor associated with fibrosis. In patients transplanted for hepatitis C virus-related cirrhosis, immunostaining of post-transplant liver biopsies for alpha-smooth muscle actin (i.e. in activated hepatic stellate cells) may identify those individuals at risk for severe recurrence. Clinicopathological papers on several forms of non-HFE hemochromatosis were published and Wilson's disease was described in individuals of 60 years or more in age. Cholestasis in childhood was expertly reviewed and histopathologic precursor lesions of hepatocellular carcinoma were also examined in a comprehensive article. SUMMARY Recent publications with impact on liver biopsy interpretation include a morphologic classification of nonalcoholic steatohepatitis in childhood, the differential diagnosis of childhood cholestasis and pathogenetic factors involved in fibrogenesis in chronic hepatitis C.

Abstract
BACKGROUND Liver fibrosis is accelerated in patients coinfected with hepatitis C virus (HCV) and human immunodeficiency virus (HIV). The reasons for this faster liver disease progression are unclear, although higher plasma HCV RNA levels and distinct HCV genotype distribution in this population, compared with in HCV-monoinfected subjects, could play a role. METHODS Liver fibrosis was assessed using elastometry in all consecutive HIV-infected patients with chronic hepatitis C who attended our institution (Hospital Carlos III, Madrid) during the past 12 months. Hepatic stiffness was measured in kiloPascal units (kPa) and was interpreted on the basis of Metavir score: no or mild fibrosis (score, F0-F1) when liver stiffness is < or =7.1 kPa, and fibrosis with septa or cirrhosis (F2-F4) when >7.1 kPa. RESULTS A total of 283 patients (71% were male; mean age, 42 years; 94% were injection drug users and 94% were receiving antiretrovirals; mean CD4 cell count, 554 cells/microL; 72% with plasma HIV RNA level of <50 copies/mL) were analyzed. The mean alanine aminotransferase level was 68 IU/L, and the mean plasma HCV RNA level was 5.9 log IU/mL. HCV genotype distribution was as follows: genotype 1, 60% of patients; genotype 2, 2%; genotype 3, 26%; and genotype 4, 12%. Overall, 164 (58%) of the patients had scores indicating advanced liver fibrosis (F2-F4), as determined using elastometry. In the univariate and multivariate analyses, respectively, a significant odds ratio (OR) for score F2-F4 was found for HCV genotype 3, compared with the other genotypes (OR, 1.9 [95% confidence interval {CI}, 1.1-3.4] vs. 4.3 [95% CI, 1.4-13.3]); for older age (OR, 1.1 [95% CI, 1.03-1.17] vs. 1.1 [95% CI, 1.01-1.25]); and for elevated alanine aminotransferase levels (OR, 1.02 [95% CI, 1.01-1.03] vs. 1.03 [95% CI, 1.01-1.04]). Although patients with HCV genotype 1 had higher mean serum HCV RNA levels than did those with HCV genotype 3 (6.1 log IU/mL vs. 5.7 log IU/mL; P=.01), patients with HCV genotype 3 tended to have F2-F4 scores more frequently than did those with HCV genotype 1 (69% vs. 58%; P = not significant). CONCLUSIONS HCV genotype 3, older age, and elevated alanine aminotransferase levels are independent predictors of advanced liver fibrosis in HCV-HIV-coinfected patients.

Abstract
OBJECTIVE To evaluate the prevalence and severity of steatosis and possible interactions between steatosis, host factors, viral factors, and treatment for HIV infection in HIV-hepatitis C virus (HCV) coinfected patients. METHODS Steatosis was assessed among 395 HIV-HCV coinfected patients who were enrolled in the ANRS trial HC02 Ribavic and for whom histological data were available. Steatosis was graded as follows: 0 (none); 1 (< 30% hepatocytes containing fat); 2 (30-70%); 3 (> 70%). RESULTS Steatosis was present in 241 patients (61%), of whom 149 (38%) had grade 1, 64 (16%) grade 2 and 28 (7%) grade 3. In multivariate analysis, the following five independent risk factors were associated with steatosis: HCV genotype 3 [odds ratio (OR), 3.02; 95% confidence interval (CI), 1.91-4.79; P < 0.0001], the mean METAVIR fibrosis score (OR, 1.43; 95% CI, 1.11-1.84; P = 0.0053), the body mass index (BMI; OR, 1.13; 95% CI, 1.05-1.21; P = 0.0013), HCV viral load (OR. 1.65; 95% CI, 1.22-2.23; P = 0.0012) and ferritin (OR, 1.13; 95% CI, 1.06-1.21; P < 0.0003). As HCV genotype 3 was a risk factor for steatosis, further exploratory analyses were stratified according to the HCV genotype (1 and 3). Factors independently associated with steatosis were BMI and HCV viral load in patients with HCV genotype 3 infection and the mean METAVIR fibrosis score, the BMI and ferritin in patients with HCV genotype 1 infection. CONCLUSION Steatosis is particularly frequent in HIV-HCV coinfected patients, who appear to have the same risk factors for steatosis as HCV monoinfected patients. None of the characteristics of HIV infection, including antiretroviral therapy, was independently associated with steatosis.
