BACKGROUND: HIV/hepatitis C-coinfected persons experience more rapid liver disease progression than hepatitis C virus (HCV) monoinfected persons, even in the setting of potent antiretroviral therapy. METHODS: We sought to articulate the role of macrophage activation and inflammation in liver disease progression by measuring serial soluble markers in HIV/HCV-coinfected women. We compared markers measured during retrospectively defined periods of rapid liver disease progression to periods where little or no liver disease progression occurred...

Soluble mannose receptor (sMR) and soluble haemoglobin scavenger receptor (sCD163) are macrophage activation markers which have previously been demonstrated to be increased in patients with inflammation, auto-immunity and malignancies. To investigate the clinical diagnostic and prognostic significance of preoperative serum sMR and sCD163, the present study investigated 143 gastric cancer (GC) patients, 66 subjects with benign gastric disease and 59 healthy controls, using an ELISA assay. Preoperative serum levels of sMR and sCD163 ranged from 0...

BACKGROUND: Recently moderate-virulence classical swine fever virus (CSFV) strains have been proven capable of generating postnatal persistent infection (PI), defined by the maintenance of viremia and the inability to generate CSFV-specific immune responses in animals. These animals also showed a type I interferon blockade in the absence of clinical signs. In this study, we assessed the infection generated in 7-week-old CSFV PI wild boars after infection with the African swine fever virus (ASFV)...

Chronic immune activation persists despite antiretroviral therapy (ART) in HIV+ individuals and underpins an increased risk of age-related co-morbidities. We assessed the Frailty Index in older HIV+ Australian men on ART. Immunometabolic markers on monocytes and T cells were analyzed using flow cytometry, plasma innate immune activation markers by ELISA, and lipidomic profiling by mass spectrometry. The study population consisted of 80 HIV+ men with a median age of 59 (IQR, 56-65), and most had an undetectable viral load (92%)...

BACKGROUND: Metabolic syndrome (MetS) and nonalcoholic fatty liver disease have become a common finding in HIV-infected patients. However, the severity, risk factors and pathogenesis of liver fibrosis in this population have been poorly documented. OBJECTIVES: To assess the impact of MetS on liver fibrosis and analyze the association between MetS, liver fibrosis and markers of adipose tissue and macrophage activation. METHODS: In a matched cohort of HIV-1-monoinfected patients with and without MetS, after exclusion of other causes of liver disease, we assessed liver stiffness measurement and measured levels of serum adipokines, homeostasis model assessment index and soluble CD163 (sCD163) and CD14 as markers of fat, insulin resistance and macrophage/monocyte activation, respectively...

BACKGROUND: TNF-like weak inducer of apoptosis (TWEAK), its receptor fibroblast growth factor-inducible 14 (Fn14) and its scavenger receptor CD163 (sCD163) have known associations with many autoimmune diseases. However, the role of the TWEAK axis in autoimmune thyroid disease (AITD) remains unclear. Therefore, the aim of this study was to investigate the role of the TWEAK-Fn14 axis in the pathogenesis of AITD. METHODS: Serum levels of soluble TWEAK (sTWEAK) and sCD163 were measured in 38 patients with Graves' disease (GD), 40 patients with Hashimoto's thyroiditis (HT), and 40 healthy controls (HCs)...

BACKGROUND AND AIM: Liver macrophages are activated in chronic hepatitis B virus (CHB) infection and play a pivotal role in hepatic inflammation and fibrosis. However, their role during anti-viral treatment is unclear. The soluble (s) macrophage activation markers, sCD163 and mannose receptor (sMR), are released during liver damage and their serum levels reflect liver disease severity and portal hypertension. We aimed to investigate associations between sCD163 and sMR and histopathological activity and fibrosis, and changes in sCD163, sMR and hepatic CD163-expression following anti-viral treatment in CHB patients...
