background worldwide, the incidence of inflammatory bowel disease (ibd) is increasing. this study aims to evaluate the diagnostic value of two serological markers, atypical perinuclear anti-neutrophil cytoplasmic antibodies (atypical-p-anca) and anti-saccharomyces cerevisiae antibodies (asca), with the intent to determinetheir relationship to ulcerative colitis (uc) and crohn's disease (cd), in...

Viral hepatitis is the most common cause of serious health problems such as liver cirrhosis and hepatocellular carcinoma (HCC). Leading to immunodeficiency disorders through different mechanisms, Human Immunodeficiency Virus (HIV) causes the development of severe secondary infections. Hepatitis A (HAV) is thought to spread by the faecal-oral route, while Hepatitis B (HBV), Hepatitis C (HCV) and...

This study was undertaken to evaluate an enzyme immunoassay (EIA) for hepatitis C virus antibody detection (anti-HCV), using just one antigen. Anti-HCV EIA was designed to detect anti-HCV IgG using on the solid-phase a recombinant C22 antigen localized at the N-terminal end of the core region of HCV genome, produced by BioMérieux. The serum samples diluted in phosphate buffer saline were added ...

BACKGROUND Occult hepatitis C virus (HCV) infection is defined as the presence of HCV-RNA in liver or peripheral blood mononuclear cells (PBMCs) in the absence of detectable hepatitis C antibody (anti-HCV) or HCV-RNA in the serum. Low concentrations of HCV-RNA may be detected in PBMCs of hemodialysis (HD) patients and this could have a great impact on the management of HD patients. OBJECTIVES...

BACKGROUND Control of hepatitis C virus infection (HCV) is an increasingly important issue. Enhancing screening coverage is necessary to discover more HCV infected subjects in community. However, a substantial population is unaware of HCV infection that needs more attention. AIM The aims of this study were to evaluate the status of HCV infected residents in remote villages, to compare charact...

BACKGROUND Symmetric polyarthritis associated with hepatitis C virus (HCV) infection frequently displays a clinical picture like rheumatoid arthritis (RA). Antibodies to cyclic citrullinated peptide (CCP) have high specificity for the diagnosis of RA. This study examined the frequency and clinical significance of anti-CCP antibodies in patients with chronic HCV infection, with and without manif...

The aim of this study was to propose a protocol for assessment of markers of infection with hepatitis B virus (HBV) and hepatitis C virus (HCV) in exposed health care professionals and to define criteria for evaluation of fitness for the job of the infected personnel. The study comprised 800 persons involved in operative procedures, including 414 surgeons, 275 nurses, and 111 anaesthetists. A g...

The aims of the present study were to profile seroprevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, and possible risk factors among hemodialysis (HD) patients in private hemodialysis units (HDU) in Surabaya, Indonesia. Sera were obtained from 180 HD patients in 4 different private HDUs and tested for hepatitis B surface antigen (HBsAg) and antibody to HCV (anti-HCV)....

The natural history of chronic hepatitis C (HCV) infections in long-term leukemia survivors has not been well characterized. We studied the prevalence of HCV infections, measured HCV RNA levels, and evaluated the severity of liver disease in patients with leukemia who achieved long-term remissions after intensive chemotherapy or bone marrow transplantation (BMT). HCV antibody tests were perform...

Hepatitis B virus/hepatitis C virus (HBV/HCV) dual infection is common among high-risk individuals. To characterize the virological and immunological features of patients with HBV/HCV dual infection, we enrolled 1,049 individuals who have been identified as injection drug users. Patients were divided into single and dual infection groups according to the serological markers. We found the averag...
