BACKGROUND HIV/HCV co-infection predisposes to accelerated liver damage and increased both liver-related and unrelated morbidity and mortality in patients with HIV infection. OBJECTIVES The aim of this study was to evaluate the prevalence of HCV infection, seropositivity, risk factors and genotype distribution among treated HIV positive patients.(More)
The outcome of viral infections is dependent on the function of CD8+ T cells which are tightly regulated by costimulatory molecules. The NK cell receptor 2B4 (CD244) is a transmembrane protein belonging to the Ig superfamily which can also be expressed by CD8+ T cells. The aim of this study was to analyze the role of 2B4 as an additional costimulatory(More)
BACKGROUND One of nine types of FABP, intestinal fatty acid binding protein (I-FABP) is primarily limited to the mature enterocytes of the small intestine, with only trace amounts identified in the stomach and large intestine. The aim of this study was to investigate the use of I-FABP as a possible plasma marker of intestinal injury in patients with(More)
BACKGROUND Natural killer (NK) cells are an important component of the innate immune defense against viruses, including hepatitis C virus (HCV). The cell culture system using HCV-permissive Huh-7.5 cells make studies on interaction of NK cells and HCV-infected target cells possible. We used this system to characterize interactions of HCV-infected Huh-7.5(More)
INTRODUCTION Psoriasis is an inflammatory and chronic skin disease associated with obesity, cardiovascular diseases, diabetes and metabolic syndrome. Adipokines, as bioactive substances secreted from adipose tissue, are involved in various metabolic diseases. AIM To investigate the association between psoriasis severity and serum adiponectin and leptin(More)
AIM Antiproliferative, pro-apoptotic and immunosuppressive activity effects suggest crucial role of transforming growth factor (TGF)-beta1, metalloproteinase (MMP)-1 and its tissue inhibitor (TIMP)-1 in the pathogenesis of acute liver injury that in some patients precede development of chronic liver diseases and fibrogenesis. The aim of this study was to(More)
PURPOSE To evaluate proton magnetic resonance spectroscopy (1H MRS) features in order to assess hepatocellular activation in chronic hepatitis C and human immunodeficiency virus/hepatitis C (HIV/HCV) co-infected patients. MATERIAL AND METHODS Liver in vivo 1H MR spectra were obtained in 14 patients with hepatitis C virus infection (HCV), 20 HIV/HCV(More)
HBsAg clearance is associated with clinical cure of chronic hepatitis B virus (HBV) infection. Quantification of HBsAg may help to predict HBsAg clearance during the natural course of HBV infection and during antiviral therapy. Most studies investigating quantitative HBsAg were performed in HBV mono-infected patients. However, the immune status is(More)
OBJECTIVES Pigment epithelium-derived factor (PEDF) is an endogenous most potential angiogenic inhibitor and increased expression of PEDF in intestinal mucosa specimens was shown in the course of ulcerative colitis (UC). The aim of the present study was to evaluate serum concentration of pigment epithelium-derived growth factor, a potent anti-angiogenic(More)
Human immunodeficiency virus (HIV) may be the cause of both primary and secondary brain diseases. In this review general features of HIV-associated neuropathology are discussed. Up to 90% of patients with AIDS have a variety of HIV-related brain diseases. Primary brain diseases including lymphocytic meningitis and HIV encephalitis are attributed directly to(More)
