OBJECTIVES: The aim of this study was to compare liver-related mortality and liver-related hospitalizations for persons living with HIV (PLWH) with and without hepatitis C virus (HCV) exposure, and to estimate the fraction of liver disease attributable to chronic HCV coinfection. METHODS: An ambispective cohort study followed PLWH between 1993 and 2014. PLWH were classified into three groups: those who were HIV-monoinfected, those who cleared HCV spontaneously and those with chronic HCV coinfection...

Background: Oxidative stress and reduced antioxidants may be a trigger for liver fibrogenesis. Reducing oxidative stress through higher antioxidant concentration may be a potential antifibrotic target.Objective: We aimed to investigate longitudinally whether plasma zinc, an antioxidant, is related to mitochondrial oxidative stress and the progression of liver fibrosis in the Miami Adult Studies in HIV (MASH) cohort.Methods: A prospective observational cohort study was conducted in 487 predominantly African American HIV-monoinfected and HIV/hepatitis C virus (HCV)-coinfected adults with a mean ± SD age of 47...

Interleukin-32 (IL-32) is a novel cytokine involved in inflammation and cancer development. IL-32 gene consists of eight small exons, and IL-32 mRNA has nine alternative spliced isoforms, and was thought to be secreted because it contains an internal signal sequence and lacks a transmembrane region. IL-32 is initially expressed selectively in activated T cells by mitogen and activated NK cells and their expression is strongly augmented by microbes, mitogens, and other cytokines. The IL-32 is induced mainly by pathogens and pro-inflammatory cytokines, but IL-32 is more prominent in immune cells than in non-immune tissues...

BACKGROUND: HIV+ patients on highly active antiretroviral therapy (HAART) with suppressed viral loads have a low incidence of HIV-associated dementia, but increased prevalence of milder forms of HIV-associated neurocognitive disorders (HAND). These milder forms of HAND are often associated with minimal histological abnormalities, and their pathophysiology is unclear. Comorbidities, altered amyloid metabolism, accelerated brain aging, and activated interferon responses are suspected to play a role in HAND pathogenesis in HAART-treated persons...

HIV/AIDS remains a major public health issue. In 2014, it was estimated that 36.9 million people are living with HIV worldwide, including 2.6 million children. Since the advent of combination antiretroviral therapy (cART), in the 1990s, treatment has been so successful that in many parts of the world, HIV has become a chronic condition in which progression to AIDS has become increasingly rare. However, while people with HIV can expect to live a normal life span with cART, lifelong medication is required and cardiovascular, renal, liver, and neurologic diseases are still possible, which continues to prompt research for a cure for HIV...

With the advent and subsequent success of antiretroviral therapy, human immunodeficiency virus (HIV) infection has largely become a chronic condition and is increasingly seen alongside metabolic disorders such as dyslipidaemia and insulin resistance. Furthermore, the administration of antiretroviral therapy (ART) itself is associated with an increase in the incidence of metabolic risk factors (namely insulin resistance, lipoatrophy, dyslipidaemia, and abnormalities of fat distribution in HIV patients). Thus, further challenges in the management of HIV patients include the management of diabetes and the metabolic syndrome, non-alcoholic fatty liver disease (NAFLD)...

Non-alcoholic fatty liver disease is one of the most frequent chronic hepatic conditions worldwide. The spectrum of non-alcoholic fatty liver disease goes from hepatic steatosis to steatohepatitis, cirrhosis, and hepatocellular carcinoma. Risk factors for non-alcoholic fatty liver disease are metabolic, mainly obesity and the accompanying consequences. Treatment and prevention of non-alcoholic fatty liver disease should target those metabolic abnormalities. The frequency of and the factors associated with hepatic steatosis in HIV infection seem to be similar to those reported in the general population, though direct comparisons are lacking...

The pathogenic mechanisms of the accelerated progression of liver injury in HIV/HCV coinfection are incompletely understood. The progression of liver disease is variable between individuals having similar risk factors, suggesting that genetic background is an important contributor. The aim of this review is to give a summary of all single nucleotide polymorphisms associated with the severity of liver disease in patients coinfected with HIV and HCV reported in the literature. Therefore, a systematic search for articles published was made, 17 of which were selected for this review...

BACKGROUND: The data on hepatitis b virus (HBV) infection in immigrants population are scanty. The porpoise of this study was to define the demographic, virological, and clinical characteristics of subjects infected with HBV chronic infection in a cohort of immigrants living in Naples, Italy. METHODS: A screening for HBV infection was offered to 1,331 immigrants, of whom 1,212 (91%) (831 undocumented immigrants and 381 refugees) accepted and were screened for hepatitis B surface antigen (HBsAg) and anti-hepatitis B core antibody (HBc)...

BACKGROUND: Hepatitis C virus (HCV) screening has taken on new importance as a result of updated guidelines and new curative therapies. Relatively few studies have assessed HCV infection in homeless populations, and a minority include women. We assessed prevalence and correlates of HCV exposure in a cohort of homeless and unstably housed women in San Francisco, and estimated the proportion undiagnosed. METHODS: A probability sample of 246 women were recruited at free meal programs, homeless shelters, and low-cost single room occupancy hotels in San Francisco; women with HIV were oversampled...

BACKGROUND: In chronic hepatitis C, the European Association for the Study of the Liver - Asociacion Latinoamericana para el Estudio del Higado recommends performing transient elastography and a blood test to diagnose significant fibrosis; test concordance confirms diagnosis. AIM: To validate this rule and improve it by combining a blood test, FibroMeter (virus second generation, Echosens, Paris, France) and transient elastography (constitutive tests) into a single combined test, as suggested by the American Association for the Study of Liver Diseases and the Infectious Diseases Society of America...

Silymarin (SM), and its flavonolignan components, alter cellular metabolism and inhibit inflammatory status in human liver and T cell lines. In this study, we hypothesized that SM suppresses both acute and chronic immune activation (CIA), including in the context of HIV infection. SM treatment suppressed the expression of T cell activation and exhaustion markers on CD4+ and CD8+ T cells from chronically-infected, HIV-positive subjects. SM also showed a trend towards modifying CD4+ T cell memory subsets from HIV+ subjects...

BACKGROUND: Although Mycobacterium tuberculosis (TB) infection may cause extrapulmonary disease in HIV-infected adults, HIV-associated hepatic TB has been poorly characterized. Our objective was to describe hepatic TB in HIV-infected adults. METHODS: Retrospective study of patients diagnosed with hepatic TB from 2005-2012 at Infectious Diseases Clinic, King Edward VIII Hospital, Durban, South Africa. RESULTS: Among twenty cases of histology-confirmed HIV-associated hepatic TB, median CD4 count was 47 cells/μl (inter-quartile range 27-107 cells/μl) and 75% (15/20) of patients had pre-existing pulmonary TB...

The mechanisms involved in the chronic hepatitis C progression are incompletely understood. The aim was to analyze the association between 2'5'oligoadenylate synthetase 1,2 and 3 (OAS1-3) and myxovirus resistance proteins 1 (Mx1) polymorphisms and severity of liver disease in human immunodeficiency virus (HIV)/hepatitis C virus (HCV) coinfected patients. We performed a cross-sectional study in 219 patients that underwent a liver biopsy. DNA genotyping for Mx1 (rs469390), OAS1 (rs2285934), OAS2 (rs1293762) and OAS3 (rs2010604) was performed by using GoldenGate assay...

BACKGROUND: Reduction of premature mortality is a UN Sustainable Development Goal. Unlike other high-income countries, age-adjusted mortality in the USA plateaued in 2010 and increased slightly in 2015, possibly because of rising premature mortality. We aimed to analyse trends in mortality in the USA between 1999 and 2014 in people aged 25-64 years by age group, sex, and race and ethnicity, and to identify specific causes of death underlying the temporal trends. METHODS: For this analysis, we used cause-of-death and demographic data from death certificates from the US National Center for Health Statistics, and population estimates from the US Census Bureau...

Viral liver diseases are frequent co-morbidities and major contributors to death in HIV-positive individuals on antiretroviral therapy. Whereas cure of hepatitis C and control of hepatitis B with antivirals avert liver disease progression in most HIV-coinfected patients, the lack of satisfactory treatment for hepatitis delta virus (HDV) infection remains a major threat for developing cirrhosis and liver cancer in this population. In the European Union and North America, sexual contact has replaced injection drug use has major transmission route for HDV in HIV-positive persons...

Liver-related morbidity and mortality is expanding in people living with HIV. Hepatocellular carcinoma (HCC), the third most lethal malignancy on a global scale, is a dominant complication of chronic liver disease and cirrhosis in patients with coexisting hepatitis. HIV infection further complicates the clinical heterogeneity of HCC, posing concurrent challenges stemming from the underlying immunological status of the patients and the ongoing need for combined antiretroviral therapy. In this article, we review the multiple clinical implications that characterize the multidisciplinary management of HCC in the context of HIV infection...

Visceral involvement in AIDS-related Kaposi's sarcoma is common, but it is rarely seen in the absence of cutaneous disease. Most patients with gastrointestinal tract Kaposi's sarcoma remain asymptomatic and are often diagnosed on endoscopy or autopsy. We report a case of a 24-year-old homosexual man who presented with rectal pain and bleeding and was found to have skin-sparing, disseminated Kaposi's sarcoma with rectum, liver, lungs, and lymph node involvement. Despite treatment with highly active anti-retroviral therapy, he developed multiorgan failure resulting in death...
