there is a well-recognized relationship between aplastic anemia and viral hepatitis. clinically apparent hepatitis precedes aplastic anemia by a period of weeks to months. hepatitis is an infrequent cause of aplastic anemia and is usually severe and fatal if untreated. the clinical features and, particularly the response to immunosuppressive therapy strongly suggest that immune mechanisms media...

Outbreaks of hepatitis-hydropericardium syndrome (HHS) caused by fowl adenovirus serotype 4 (FAdV-4) and inclusion body hepatitis (IBH) related to FAdV-8b FAdV-11 have been increased in chickens China since 2015. Clinical concurrent infections FAdV-4, FAdV-8b, are quite common, yet there no commercially available trivalent vaccines against infection these three serotypes. In our previous study,...

Asymptomatic hepatitis B infection is characterized as a type of hepatitis in which hepatitis B surface antigen is present in the patient's peripheral blood despite the absence of clinical symptoms. Previous studies have shown that a particular genotype may effect clinical manifestations of hepatitis B infection; hence, the aim of the current study was to determine the frequency of hepatitis B ...

Hepatitis A is a very common infection in developing countries. It is frequent in childhood and is mostly asymptomatic in early childhood. However, its clinical presentation may occur over a large spectrum from nonicteric to a fulminating hepatic failure form. The duration of his incubation period was 2-6 weeks and thereafter clinical symptoms such as weakness, appetite and nausea appeared. The...

conclusions one in five patients undergoing maintenance dialysis in hamadan is seropositive for hepatitis e immunoglobulin g antibody. future studies are needed to investigate the factors contributing to the observed high prevalence rate and the possibility of parenteral transmission of hepatitis e. results thirty patients (19.2%), were seropositive. seropositive patients were not significantly...

Pseudoporphyria is an uncommon bullous disease with similar clinical and histopathological findings to porphyria cutanea tarda, in the absence of detectable porphyrin elevation. We present a 34-year-old man with clinical and histological findings compatible with porphyria cutanea tarda, whose his urinary uroporphyrin was negative and we concluded that he was a case of pseudoporphyria. Concomita...

  Background and Objective: Presence of hepatitis B core antibody (anti-HBc) in the absence of hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) is defined, as isolated anti-HBc. little is known about the clinical significance of the isolated anti-HBc in hepatitis B virus (HBV) infections. The aim of this study was to assess the significance of anti-HBc as the onl...

INTRODUCTION Hepatitis B and C coinfection is commonly seen in clinical practice. In coinfected individuals, high levels of hepatitis C viremia are often associated with low levels of serum hepatitis B DNA. Hepatitis B reactivation in hepatitis C-infected patients treated with pegylated interferon and ribavirin has been reported, but severe or fulminant reactivation is uncommon. Hepatitis C tre...

Background and Aims: Hepatitis E virus (HEV) infection is usually a self-limited viral disease that causes acute hepatitis and may progress to chronic hepatitis in immunosuppressed individuals. It seems that hemodialysis patients and HIV infected people are more exposed to HEV infection. The aim of this study was to evaluate the extent of HEV infection in hemodialysis and HIV infected patients ...
