BACKGROUND & AIMS The quantifiable level of HBsAg has been suggested as a predictor of treatment response in chronic hepatitis B. However, there is limited information on HBsAg levels considering the dynamic natural course of HBV-infection. This study aimed to determine HBsAg levels in the different phases of HBV-infection in European HBsAg-positive(More)
BACKGROUND Hepatitis B surface antigen (HBsAg) loss is the ultimate goal of antiviral therapy and its prediction may be important for treatment individualization. Quantitative HBsAg (qHBsAg) has been shown to predict response to interferon-α, but few studies have analysed qHBsAg during treatment with nucleoside/nucleotide analogues (NAs). Serum(More)
OBJECTIVES Psoriasis has been considered as a systemic disease associated with obesity, cardiovascular diseases and metabolic syndrome. Adipokines have influence on many metabolic processes. Aim of this study was to evaluate the effect of conventional topical treatment on serum adiponectin and leptin levels in patients with psoriasis. METHODS Forty-nine(More)
Metabolic and morphologic abnormalities as well as disturbances in bone mineral density (BMD) are prevalent among HIV-infected patients, particularly during highly active antiretroviral treatment (HAART) [1–3]. Hyperlipidaemia may affect up to 60–80% of HIV-infected patients treated with protease inhibitors (PI) and is commonly associated with abnormalities(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)
AIM To provide the clinical and epidemiological data of inflammatory bowel disease (IBD) patients of North-Eastern Poland. METHODS A total of 248 IBD patients diagnosed and hospitalized in the Department of Infectious Diseases in Bialystok between 1990 and 2003 were included in the study. We analyzed age, sex, education, characteristics of job, type of(More)
AIM The prevalence of renal disease in human HIV-infected individuals varies between 2% and 10%. Many reports have demonstrated the beneficial effect of antiretroviral (ARV) therapy on slowing the progression of renal diseases. The aim of our cross-sectional study was to determine serum cystatin C concentration in different stages of HIV infection and the(More)
Recent studies provided in vivo evidences of an increased angiogenesis in animal model of portal hypertension and cirrhosis which was linked to increased expression of vascular endothelial growth factor. The aim of study was to evaluate the plasma concentration of VEGF and its receptors in liver cirrhosis and the possible association with the degree of(More)
BACKGROUND MR proton spectroscopy (1H MRS) enables early detection of metabolic changes, which occur in the course of AIDS Dementia Complex Syndrome (ADC). The goal of the study was the evaluation of highly active antiretroviral therapy (HAART) and its influence on the character and intensity of metabolic changes in brain 1H MRS spectra in clinically(More)
BACKGROUND & AIMS Pegylated interferon-alpha (PEG-IFNalpha), in combination with ribavirin, controls hepatitis C virus (HCV) infection in approximately 50% of patients by mechanisms that are not completely understood. Beside a direct antiviral effect, different immunomodulatory effects have been discussed. Natural killer (NK) cells might be associated with(More)
