AIM To observe the imbalance between T helper cell Th1 and Th2 cytokines in several chronic hepatitis disease at different stages of disease progression. METHODS We measured the cytokine levels of Th1 (IL-2 and IL-2R), Th2 (IL-10) and the pro-inflammatory cytokines (IL-6 and IL-6R and TNF and TNF-RI and II) by the ELISA technique in the sera of 33(More)
OBJECTIVE Viral infection, especially caused by herpes viruses, is now recognized as an important cause of morbidity and mortality in immunocompromised cancer patients. This study aimed at studying seroprevalence of 3 herpes viruses Herpes simplex virus types 1 and 2 (HSV 1 and 2), Epstein-Barr virus (EBV), and cytomegalovirus (CMV) in children with acute(More)
Combined pegylated interferon-α and ribavirin therapy has sustained virological response (SVR) rates of 54% to 61%. Pretreatment predictors of SVR to interferon therapy have not been fully investigated yet. The current study assesses a group of chemokines that may predict treatment response in Egyptian patients with chronic HCV infection. CXCL5, CXCL9,(More)
BACKGROUND/AIM Infection with hepatitis C virus (HCV) frequently results in a persistent infection, suggesting that it has evolved efficient mechanism(s) for blocking the host cell's innate antiviral response. The immune response to virus infection results in activation or direct induction of the interferon regulatory factors (IRFs), which are a family of(More)
BACKGROUND Helicobacter pylori is one of the most common bacterial strains causing chronic infections, affecting over one half of the world's population. There is increasing interest in noninvasive methods for diagnosing H. pylori infection. The aim of the study was to evaluate 3 different noninvasive methods of diagnosis: the stool antigen test (HpSA), the(More)
Hepatitis C virus (HCV) genome contains two envelope proteins (E1 and E2) responsible for the virus entry into the cell. There is a substantial lack of sequences covering the full length of E1/E2 region for genotype 4. Our study aims at providing new sequences as well as characterizing the genetic divergence of the E1/E2 region of HCV 4a using our new(More)
BACKGROUND BACKGROUND AND AIM Human papilloma viruses (HPVs) are small DNA tumor viruses that infect epithelial tissues and cause warts. One of the viral genes responsible for HPV's oncogenic activity is E6 which is known to inactivate the cellular p53 tumor suppressor gene. We aim to detect the presence of HPV infection and its different types in human(More)
BACKGROUND Human papillomavirus (HPV) types 16 and 18 are associated with cervical carcinogenesis. This is possibly achieved through an interaction between HPV oncogenic proteins and some cell cycle regulatory genes. However, the exact pathogenetic mechanisms are not well defined yet. METHODS We investigated 110 subjects (43 invasive squamous cell(More)
The global rising incidence of hepatocellular carcinoma (HCC), which parallels the increase of hepatitis C virus (HCV) prevalence, has sparked a renewed interest in discovering additional HCC serum markers. In this study, we investigated the clinical use of serum E-cadherin, ICAM, MMP-2, VEGF, OPN and β-catenin as potential diagnostic makers for(More)
Recently, a novel virus designated SEN virus (SENV), which is thought to be related to posttransfusion hepatitis, was discovered. The aim of the present study was to investigate the prevalence and clinical significance of 2 SENV variants (SENV-D and SENV-H) in patients with hepatocellular carcinoma (HCC) and healthy adults. Also, to investigate the possible(More)
