Human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) are the three most common chronic viral infections seen in the world. All three viruses share modes of transmission and hence co-exist in the same host at significantly high rates. HIV-induced immunosuppression has deleterious effects on the natural history, pathophysiology, diagnosis, therapeutic responses...

INTRODUCTION We set out to determine the seroprevalence of hepatitis B and hepatitis C viruses among human immunodeficiency virus infected individuals and its impact on pattern of presentation. METHODOLOGY A serological study for hepatitis B and hepatitis C viruses was performed on 260 HIV-positive individuals. These patients were tested for the presence of hepatitis B surface antigen and ant...

OBJECTIVE To estimate the prevalence of hepatitis B virus and C virus infections and their genotypes and analyze the risk factors for the markers of exposure to hepatitis B virus in female sex workers in a region of intense sex trade. METHODS This is a cross-sectional study performed with four hundred and two female sex workers in Goiânia, Brazil. Data have been collected using the Respondent...

BACKGROUND The World Health Organisation estimates that 2 billion people have been infected with hepatitis B and about 180 million people infected with hepatitis C worldwide. More than 350 million have chronic hepatitis B and 130 million have chronic hepatitis C infection. Most infections of hepatitis B and C are from unsafe injection practices, both medical and nonmedical; from household conta...

background association of hepatitis b virus (hbv) genotype c with hepatocellular carcinoma (hcc) development remains controversial. hbv basal core promoter (bcp) double mutations (t1762a1764) are very strong confounding factors of genotypes b and c in hcc development. objectives to investigate the association of hbv genotype c with hcc development after controlling for bcp double mutations. mat...

Background: Although regular frequent blood transfusion improves overall survival of multi-transfused patients like β-thalassemic ones, it carries a definite risk of infection with blood-borne viruses such as viral hepatitis. This study was done to determine seropositivity of hepatitis B virus (HBV), hepatitis C virus (HCV), and Human Immunedeficiency Virus (HIV) infections among β-th...

conclusions hepatitis a causes an acute infection. the patients usually recover after a few weeks or months. fulminant hepatitis can be observed in hav infection but chronic infection does not exist. extrahepatic complications and cardiac disorders are often reported in association with hepatitis c and b viruses, but they are very rare in hav infections. case presentation we present a 14-year-o...

Background: Libya is one of the largest country in Africa and it has the longest cost in the Mediterranean basin facing the European countries. The prevalence of viral hepatitis in Libya is not well documented. Here in we report on the largest cross sectional study in Libya including a total of sixty five thousands, seven hundred and sixty one [65761] individuals in order to ; evaluate the epid...
