INTRODUCTION Human host immune response following infection with the new variant of A/H1N1 pandemic influenza virus (nvH1N1) is poorly understood. We utilize here systemic cytokine and antibody levels in evaluating differences in early immune response in both mild and severe patients infected with nvH1N1. METHODS We profiled 29 cytokines and chemokines(More)
The aim of this prospective study was to analyze the incidence of serious infections and changes in immunological markers after liver transplantation (LT) in a cohort of patients with hepatitis C virus (HCV). This study included 34 patients who had LT, 20 patients with HCV etiology (HCV group), and 14 patients with alcoholic etiology (non-HCV group).(More)
BACKGROUND Noninvasive tests are increasingly being used for the assessment of liver fibrosis. We aimed to develop a serum index for the identification of advanced fibrosis (F>or=3) in HIV/hepatitis C virus (HCV)-coinfected patients. METHODS We carried out a cross-sectional study on a group of 195 patients comprised of an estimation group (EG; n=127) and(More)
BACKGROUND The cytokine profile plays an important role in treatment outcome of hepatitis C virus (HCV) infection, and probably modulates the immune response against HCV. The aim of this study was to evaluate which cytokines affect the response to interferon-α (IFN-α) and ribavirin therapy and how these cytokines change 72 weeks after starting anti-HCV(More)
BACKGROUND Hyaluronic acid (HA) serum levels correlate with the histological stages of liver fibrosis in hepatitis C virus (HCV) monoinfected patients, and HA alone has shown very good diagnostic accuracy as a non-invasive assessment of fibrosis and cirrhosis. The aim of this study was to evaluate serum HA levels as a simple non-invasive diagnostic test to(More)
Background. Use of antiretroviral therapy has resulted in a decrease in morbidity and mortality rates in human immunodeficiency virus type 1 (HIV-1)-infected children.Methods. We performed a retrospective study involving 427 children to determine the effectiveness of different antiretroviral therapy protocols on clinical outcome. The follow-up period was(More)
BACKGROUND CXCL10 may contribute to the host immune response against the hepatitis C virus (HCV), liver disease progression, and response to HCV antiviral therapy. The aim of our study was to analyze the relationship among virological, immunological, and clinical characteristics with plasma CXCL10 levels in human immunodeficiency virus (HIV)/HCV-coinfected(More)
BACKGROUND The introduction of highly active antiretroviral therapy (HAART) has influenced the incidence of cancer in people with human immunodeficiency virus (HIV) infection. The aim of this study was to evaluate changes in the pattern of cancer rates in HIV-infected children on HAART during over a decade of follow-up. PATIENTS AND METHODS We carried out(More)
BACKGROUND Common variable immunodeficiency (CVID) is a very heterogeneous syndrome defined by impaired immunoglobulin production. The primary defect remains unknown, but many reports describe peripheral blood T and B lymphocyte dysfunctions in a substantial proportion of CVID patients. Immunophenotypic alterations on memory B lymphocytes correlate with(More)
The aim of this study was to evaluate the influence of clinical and epidemiological characteristics of 183 HIV/HCV coinfected patients and HCV clearance after antiviral treatment on serum sFas and sFasL levels. Thirty out of 183 patients underwent HCV antiviral therapy with IFN-α + RBV for a duration of 48 weeks. HCV genotype 1 and homeostasis model(More)
