Abstract Adherence to antiretroviral therapy (ART) has markedly improved HIV disease management, and significantly reduced HIV/AIDS-associated morbidity and mortality. Although recent studies suggest a relationship between smoking and suboptimal adherence to ART, a more in-depth understanding of this relationship is needed. We conducted a secondary analysis using data from a ...

Tobacco use is the largest preventable cause of death in the United States. Associations between cigarette smoking and HIV risk behaviors were examined among 669 injection drug users (IDU) in the 2006 wave of the National HIV Behavioral Surveillance System in Baltimore, Maryland, using respondent-driven sampling. The adjusted prevalence of ...

Aims and objectives.  The present study provided the first examination of cigarette smoking status and motivation before and after the diagnosis of hepatitis B in Chinese hepatitis B smokers. Background.  Cigarette smoking is known to contribute to the severity of chronic liver diseases. However, the rates of cigarette smoking remain ...

Liver disease due to hepatitis C virus (HCV) infection is a leading cause of non-AIDS-related morbidity and mortality in patients infected with HIV. We assessed the frequency of and predictors for initiation of treatment for HCV infection among patients coinfected with HCV/HIV enrolled in the HIV Outpatient Study (HOPS) during ...

Summary.  The efficacy of current hepatitis C therapy in HIV/HCV-coinfected patients is largely dependent on HCV genotype. The annual prevalence of HCV genotypes/subtypes and their influence on HCV clearance with antiviral treatment were examined in a dynamic cohort of HIV/HCV-coinfected patients followed up in Madrid since 2000. Patients entered the ...

Summary.  Hepatitis C virus (HCV) is a widespread chronic infection that shares routes of transmission with human immunodeficiency virus (HIV). Thus, coinfection with these viruses is a relatively common and growing problem. In general, liver disease develops over years with HIV coinfection, when compared to decades in HCV monoinfection. The ...

The pathogenesis of HIV/hepatitis C virus (HCV) coinfection is poorly understood. We examined markers of oxidative stress, plasma antioxidants and liver disease in HIV/HCV-coinfected and HIV-monoinfected adults. Demographics, medical history, and proof of infection with HIV, hepatitis A virus (HAV), hepatitis B virus (HBV) and HCV were obtained. HIV viral ...

Abstract The presence of HBV genomes with deletions at the basal core promoter (BCP) is associated with more aggressive liver disease. This 3-year longitudinal analysis of two HIV-HBV-coinfected patients allowed identification of three deletions with dissimilar abundance and permanence into the HBV quasispecies composition. These deletions may contribute to HBV ...

HIV/hepatitis C virus (HCV) coinfection causes accelerated liver disease compared to HCV monoinfection, and only 30-60% of HIV/HCV-coinfected individuals respond to HCV therapy with pegylated interferon and ribavirin. There are currently no biomarkers that predict treatment response in these coinfected patients. We investigated whether there is an association between HCV ...

Maraviroc is the first CCR5 antagonist to be approved for the treatment of HIV-1 infection. It is generally well tolerated, with a similar side-effect profile to placebo in controlled studies. Many agents used to treat HIV disease are associated with the potential for hepatotoxicity. The hepatic effects of maraviroc were ...

Liver disease related to infection with hepatitis C virus (HCV) and/or hepatitis B virus (HBV) is a frequent cause of morbidity and mortality in those infected with the human immunodeficiency virus (HIV) in this era of highly active antiretroviral therapy (HAART). Although progress has been made in the treatment of ...

Hepatic steatosis is common in persons with HIV and hepatitis C virus (HCV); yet biopsy measurement of steatosis is prone to sampling error. We compared magnetic resonance spectroscopy (MRS) measurement of steatosis to histology in HIV/HCV-coinfected patients and explored the associated adipose tissue and metabolic factors. Cross-sectional analysis of 42 ...

Chronic hepatitis C is an emerging issue in the management of human immunodeficiency virus (HIV) disease because both diseases have the same route of transmission, leading to a very high prevalence of hepatitis C virus (HCV)-coinfection in the HIV-positive patient population. Lopinavir is extensively metabolized by the hepatic cytochrome P450 ...

Patients with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) coinfection for whom prior treatment of HCV with interferon-ribavirin has failed may require subsequent treatment with new HCV protease inhibitors (PIs).

Coinfection with hepatitis B virus (HBV) is not uncommon in human immunodeficiency virus (HIV)-infected individuals and patients with HIV-HBV coinfection are at high risk for progression of liver disease. Current guidelines regarding the treatment of HIV infection recommend that patients who are coinfected with HIV and HBV receive highly active ...

Hepatitis C virus (HCV) infection is the most important cause of chronic hepatitis, cirrhosis and end-stage liver disease leading to liver transplantation worldwide. Chronic infection by HCV causes liver fibrosis, which is accelerated by unknown mechanisms in patients with human immunodeficiency virus-1 (HIV-1) coinfection. Although the genetic variability of both ...

The efficacy of antiviral therapy with pegylated interferon (PEGIFN) plus ribavirin (RBV) in patients with HIV and hepatitis C virus (HCV) coinfection is limited. Intravenous silibinin (ivSIL), a milk thistle extract with proven antiviral effects represents a novel therapeutic strategy for virological nonresponders. We report a case of an HIV-HCV ...

The purpose of this study was to evaluate the relationship between serum filamentous (F)-actin antibody titers and severity of hepatitis present in hepatitis C virus (HCV)-infected patients. Liver biopsy samples from 18 HCV monoinfected and 20 HCV-HIV coinfected patients were graded with respect to the degree of hepatitis activity and ...

Hepatitis B virus is a common cause of acute liver failure. It can be especially problematic in patients coinfected with hepatitis C, hepatitis D or human immunodeficiency virus. In addition, immunosuppression-associated hepatitis B reactivation is being increasingly recognized following chemotherapy, biologic therapy, and organ transplantation. This article highlights treatment options ...

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 ...

OBJECTIVES: Although the reproducibility of transient elastometry (TE) in hepatitis C virus (HCV)-monoinfected patients seems to be high, this may not be the case in HIV/HCV-coinfected patients because of different degrees of steatosis and/or inflammation. This study was aimed to determine the interobserver concordance of TE measurements in HIV/HCV-coinfected patients. ...

A newly described cytokine, interleukin-27 (IL-27), that activates naive CD4 T cells, has recently been shown to be an anti-HIV cytokine.

Statins are effective therapy for hypercholesterolemia and are commonly indicated in patients with HIV and hepatitis C virus infections. Unfortunately, in patients coinfected with these viruses, the safety of statins has not been conclusively evaluated. We retrospectively evaluated five coinfected patients in our outpatient clinic who received statin therapy. Although ...

The most important factors to predict the sustained virological response (SVR) are the genotype and the fibrosis grade, although there are other predictive factors to be considered, mainly in HCV/HIV coinfected patients. To evaluate different prognostic factors to obtain the SVR in HCV monoinfected and HCV/HIV coinfected genotype 1 patients ...

SUMMARY: Patients with inherited bleeding disorders frequently suffer from chronic hepatitis C virus (HCV) mono- or human immunodeficiency virus (HIV)/HCV coinfection. Non-invasive markers for liver fibrosis are warranted for these patients. We tested a large cohort of haemophilic patients with HCV mono- or HIV/HCV coinfection for correlation of transient elastography ...

The association of HIV infection and hepatitis C virus (HCV) infection often occurs because both viruses share the same transmission routes, increasing the possibility of HIV/HCV coinfection. World prevalence greater than 30% of coinfected cases is estimated, and it can reach 90% depending on the transmission route. With the aim ...

Coinfection with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) has emerged as a major cause of morbidity and mortality due to liver disease. Interferon-based therapy response rates have been disappointingly low. Baseline HCV complexity and the relationship between complexity and viral kinetic parameters has not been well described ...

Simple noninvasive tests to predict fibrosis, as an alternative to liver biopsy (LB), are needed. Of these, the aspartate aminotransferase (AST) to platelet ratio index (APRI) and the Forns index (FI) have been validated in HIV/hepatitis C virus (HCV) coinfection. However, these indexes may have lower diagnostic value in situations ...

Among HIV-infected patients, hepatitis C virus (HCV) coinfection is associated with lower cholesterol levels, but it remains unclear how it affects cardiovascular outcomes. We performed logistic regression to evaluate acute myocardial infarction (AMI) and cerebrovascular disease (CVD) events by HCV status among HIV-infected US veterans in the highly active antiretroviral ...

To examine the effect of hepatitis C virus (HCV) on the prevalence of chronic kidney disease (CKD) among veterans with HIV and to evaluate independent associations of HCV and CKD with mortality. We studied a national cohort of HIV-infected patients receiving care through the Veterans Healthcare Administration from 1998 to ...

CCR5 antagonists block HIV cell entry through competitive binding to the CCR5 receptor present on the surface of CD4(+) cells. The CCR5 receptor is also present on CD8(+) cells involved in clearing hepatitis C virus (HCV). The goal of the present study was to examine the short-term safety of a ...

Unexpected cases of severe liver disease in HIV-infected patients have been reported and an association with didanosine (ddI) has been suggested. Transient elastography (TE) might detect patients harbouring such a condition. Our objective was to search for the presence of abnormal liver stiffness (LS) in a cohort of HIV-infected patients ...

The influence of biological sex on human immunodeficiency virus (HIV) antiretroviral treatment outcome is not well described in HIV-hepatitis C (HCV) coinfection. We assessed patients' clinical outcomes of HIV-HCV coinfected patients initiating antiretroviral therapy attending the Ottawa Hospital Immunodeficiency Clinic from January 1996 to June 2008. We assessed 144 males ...

Because high serum low-density lipoprotein (LDL) and total cholesterol concentrations before treatment have been found to be significant positive prognostic factors for a sustained virological response to HCV therapy in monoinfected patients, the aim of this study was to assess this relationship in HIV-HCV-coinfected patients. Pretreatment fasting lipid parameters (in ...

Coinfection with hepatitis B virus (HBV) or hepatitis C virus (HCV) in HIV-infected patients receiving a commonly used nevirapine-based antiretroviral therapy is a major concern for African clinicians owing to its high prevalence, the infrequent testing and treatment of viral hepatitis, and the impact of liver disease on the tolerability ...

Liver disease is a leading cause of morbidity and mortality among patients coinfected with HIV and hepatitis C (HCV), yet few HIV coinfected patients actually receive HCV treatment. Providers must first be willing to prescribe treatment, but the patient ultimately makes the decision to accept or decline a treatment recommendation. ...

HIV/hepatitis C virus (HCV) coinfected patients are known to have lower sustained viral response (SVR) rates than HCV monoinfected patients. However, the role of CD4+ T-cell counts on viral kinetics and outcome is not fully understood. HCV RNA kinetics (bDNA v3, lower limit of detection [LD] = 615 IU/mL) was ...

A 45-year-old male active homosexual was given a diagnosis of HIV-1 and acute hepatitis B in August 2007. Since his liver function became rapidly impaired, anti-HBV therapy with oral administration of entecavir (ETV) was started, and resulted in a favorable outcome. However, serum concentration of HIV-RNA decreased by log 1.26 ...

Replicative senescence of peripheral blood mononuclear cells (PBMC) plays an important role in the pathophysiology of chronic viral infections. Although there are controversial reports concerning telomerase activity in HIV monoinfected subjects, no data on HIV-HCV coinfected individuals is available. In this cross-sectional study telomerase activity was quantified in non-stimulated and ...

Clinical, biological and virological data were collected every 3 months. Liver-related mortality ...

BACKGROUND: CD81 is expressed on lymphocytes and confers HCV viral infectivity support. The aim of our study was to quantify CD81 expression in peripheral blood B- and T-cells of HCV/HIV-coinfected patients and healthy subjects to examine its association with several HCV virological characteristics and the therapeutic responsiveness to HCV antiviral ...

The aim of this study was to evaluate the effect of GB virus C on laboratory markers and histological parameters among HIV-seropositive patients coinfected with HCV. Lower degrees of hepatic lesions were observed in the triple-infected patients, in comparison with HIV-HCV coinfected patients who were negative for GBV-C RNA.

Liver disease is a leading cause of death among patients with HIV coinfected with hepatitis C (HCV); yet, studies show that less than 10% receive HCV treatment, in part because of limited treatment response, high treatment toxicity, and psychosocial barriers to treatment readiness. Using a process model framework, we sought ...

Chronic immune activation is a driver of human immunodeficiency virus type 1 (HIV-1) disease progression. Here, we describe that subjects with chronic hepatitis C virus (HCV)/HIV-1 coinfection display sharply elevated immune activation as determined by CD38 expression in T cells. This occurs, despite effective antiretroviral therapy, in both CD8 and ...

Whether hepatitis C virus coinfection might accelerate atherosclerosis in HIV-infected individuals is unclear. We examined the relationship of HIV and hepatitis C virus with carotid artery intima media thickness and the presence of carotid plaques in the Women's Interagency HIV Study. Hepatitis C virus infection was not associated with greater ...

Hepatic stellate cells (HSCs) mediate hepatitis C virus (HCV)-related liver fibrosis, and increased HSC activation in human immunodeficiency virus (HIV)/HCV coinfection may be associated with accelerated fibrosis. We examined the level of HSC activation in HIV/HCV-coinfected and HCV-monoinfected subjects and its relationship to the level of activation and gene expression ...

BACKGROUND: Liver stiffness (LS) measured by transient elastometry is associated with portal pressure in hepatitis C virus (HCV)-monoinfected patients and could predict the presence of esophageal varices in these subjects.
