Abstract The importance of hepatitis B virus (HBV) genotypes for disease progression and response to interferon‐alpha‐based treatment is well established. While almost all patients in the Mediterranean area are infected with HBV genotype D, A dominant Northern Europe. However, distribution unknown several Central Eastern European countries. Data described 1313 HBsAg‐positive recruited at 14 referral centers eight There were only very few cases B, C, E, F, H infection while D found 42% 48%...

<h3>Background</h3> Tryptophan metabolism via the kynurenine pathway is considered link between immune and endocrine systems. Dysregulation of serotonergic transmission can stem from direct influence interferon-α on activity receptors 5-HT<sub>1A</sub> 5-HT<sub>2A</sub>, its indirect effect tryptophan metabolism. Induction increases concentration neurotoxic metabolites, derivatives linked to onset depression. The aim our study was evaluate relationships depressive symptoms kynurenine,...

Killer cell immunoglobulin-like receptors (KIR) are the most polymorphic of natural killer (NK) cells. Their activity diversifies functions NK cells in antiviral immune response, so presence certain KIR may affect transmission HIV-1. The aim study was to evaluate influence genes on susceptibility HIV-1 infection Polish population depending route exposure. We determined frequencies activating (2DS1, 2DS2, 2DS3, 2DS4f, 2DS4del, 2DS5, 3DS1) and inhibitory (2DL1, 2DL2, 2DL3, 2DL5, 3DL1) KIRs...

Summary. Detection of residual HCV in individuals with SVR after treatment CHC can be significantly heightened by analyzing ex vivo mitogen‐activated T and B lymphocytes applying sensitive nucleic acid amplification assays. However, it remained unknown if synergistic activation monocytes would further augment detection, viral replication becomes universally upregulated treated cells, examining sequential sera lymphoid cells improve detection occult infection. Using paired collected 1 year...

To gain insight into HIV transmission we estimated the proportion of those recently infected. We examined data from HIV-positive patients and a random 10% sample HIV-negative tested at Voluntary Counseling Testing sites in Poland 2006. Archived samples positive were by three assays to differentiate recent long-standing infection. Using logistic regression, association infection (at least one assay) with age, sex, exposure category, interval between self-reported previous test. Of 13,511...

We assessed the prevalence of anti-hepatitis C virus (anti-HCV) antibodies and markers hepatitis B (HBV) infection in patients three haemodialysis centres before initiating anti-HBV vaccinations. Of 94 patients, 39 (41.5%) were anti-HCV positive (+) 81 (86.2%) core antigen (HBc) positive. There was a high rate anti-HBc positivity among (92.3%), although presence not significantly related to each other. Multiple blood transfusions (> 5 units) risk factor for development HCV (P < 0.02), while...

Based on investigations of liver biopsy material, certain cellular genes have been implicated as correlates success or failure to interferon alpha-ribavirin (IFN/RBV) therapy against hepatitis C. The current study aimed at determining whether expression host thought be relevant HCV replication in the would correlated with infection status peripheral blood mononuclear cells (PBMCs) and also patient responsiveness IFN/RBV treatment. Therefore, PBMCs from patients chronic C responding (n = 35)...

Cytokine response against hepatitis C virus (HCV) is likely to determine the natural course of infection as well outcome antiviral treatment. However, role particular cytokines remains unclear.

Twenty-six different transcripts measured quantitatively peripheral blood mononuclear cells (PBMC) before after therapy correlated clinical liver...

The prevalence of HCV infection in people with hemophilia is substantially higher than that the general population (63% - 98%). Multiple transfusions and substitutive therapy have also been linked to a high risk HBV HIV transmission. However, other blood-borne viral infections this less well known.This study aimed assess co-infection viruses Polish HCV-infected hemophiliacs.Seventy-one individuals, majority whom were male (94.36%), who had congenital bleeding disorders (60 A, five B, six...

Hepatitis C virus (HCV) is a primarily hepatotropic virus, but hepatocytes are not the only localization of its replication. It still unclear if extrahepatic HCV replication, measured as detection RNA negative strand in peripheral blood mononuclear cells (PBMCs) before initiation treatment, has an influence on therapy response. Detection sites for assessment efficacy routinely used clinical practice. The aim study was to evaluate whether replication PBMCs affects rate sustained virological...

Hepatitis C virus (HCV) resistance-associated variants (RAVs) have been shown to adversely affect treatment response of direct-acting antivirals. Identifying pre-existing RAVs and transmission networks among HIV/HCV genotype 1 (G1)-infected patients from Poland will assist in shaping surveillance strategies for HCV.NS3 NS5A sequences were obtained samples 112 antiviral-naive G1 (45 G1a 67 G1b), which 74 chronically infected 38 diagnosed with acute hepatitis (AHC). identified using...
