BACKGROUND Human immunodeficiency virus type 2 (HIV-2) infection is characterized by a slower progression than HIV type 1. It is not known whether markers of inflammation such as high-sensitivity C-reactive protein (hsCRP), interleukin 6 (IL-6), and soluble CD14 (sCD14) may predict disease progression among HIV-2 patients. METHODS We performed longitudinal retrospective analysis using 384 sam...
COVID-19 has become a planetary emergency which is seriously threatening human health. Comparative studies can shed light on the molecular mechanisms of formation humoral antiviral immunity in persons who have undergone disease and been vaccinated against SARS-CoV-2 virus. Serum levels biomarkers inflammation cytokine storm (procalcitonin, sCD14, sLBP, sTREM1, IL-6, IL-8, IL-10, sWnt5a, TNFα TN...
In this study we sought to determine the contribution of microbial translocation to febrile episodes with no attributable microbiological cause (Fever of Unknown Origin, FUO) in an adult febrile neutropaenic cohort. Endotoxin concentrations were measured with the chromogenic Limulus Amoebocyte Assay and used as a direct measure of bacterial products whilst soluble CD14 (sCD14), measured with EL...
PURPOSE The detection of bacterial lipopolysaccharide (LPS) by human cells is facilitated by LPS-binding protein (LBP) and soluble (s)CD14. The effects of these proteins on chemokine release and adhesion molecule expression in cultured human corneal fibroblasts were examined. METHODS The release of chemokines into culture supernatants and the expression of the intercellular adhesion molecule ...
BACKGROUND Cell-wall components of Gram-positive and Gram-negative bacteria induce the production of cytokines in human peripheral blood mononuclear cells. These cytokines are the main mediators of local or systemic inflammatory reaction that can contribute to the development of innate immunity. AIMS This study was performed to analyze the involvement of CD14 molecule in the activation of hum...
Background. We assessed immune activation after antiretroviral therapy (ART) initiation to understand clinical failure in diverse settings. Methods. We performed a case-control study in ACTG Prospective Evaluation of Antiretrovirals in Resource-Limited Settings (PEARLS). Cases were defined as incident World Health Organization Stage 3 or 4 human immunodeficiency virus (HIV) disease or death, ...
PURPOSE Lipopolysaccharides (LPS), a major component of the cell membrane of gram-negative bacteria, are the main stimulants of the host immune response, initiating inflammatory changes and responsible for periodontal tissue destruction. The mCD14, which is found primarily on monocytes and macrophages, is the key membranous receptor involved in LPS binding. CD14 is also present in the serum as ...
Intercellular adhesion molecule 1 (ICAM-1) is involved in the accumulation and activation of leukocytes in inflammatory diseases such as periodontitis. As reported previously, ICAM-1 is up-regulated on cultured human gingival fibroblasts (HGF) by exposure to lipopolysaccharide (LPS), suggesting a specific LPS recognition mechanism. We therefore investigated the role of CD14, an LPS receptor, in...
OBJECTIVE Timely detection of serious bacterial infections or prediction of sepsis and death is of paramount importance in neutropenic patients especially in oncology settings. The aim of this study was to determine a rapid and secure predictor of sepsis in severe neutropenic cancer children. METHODS In addition to blood culture, we have evaluated serum soluble CD14 on this role and measured ...
OBJECTIVES Several clinical trials have demonstrated that daily treatment of HIV-infected individuals with the antiherpes drug acyclovir slightly decreases HIV-1 viral load and slows disease progression. This study examines if this slowing in clinical progression is a direct cause of the decrease in viral load or an indirect effect of lower immune activation due to lower levels of herpetic reac...
