Hepatomegaly, decrease in the liver paranchymal echo and increase in the gallbladder wall thickness has been shown in acute viral hepatitis. The present study was done to determine sonographic changes in acute viral hepatitis. We performed liver and bile ducts sonography and specific tests on 42 patients (mean age: 31.5 and 61% male) with acute viral hepatitis. Gallbladder wall thickness was se...
Two antigen-antibody systems were Out of 42 sera from patients with acute viral hepatitis 33 were positive for HBsAg,all HBsAg positive individuals possessed anti-HBc. From 11 blood donors sera 8 were positive for HBsAg and 9 were Positive for anti-HBc;2 leprosy sera were tested,both of them were positive for HBsAg and anti-HBc. 5 miscellaneous samples,z·were positive for HBsAg and anti-HBc...
Abstract Background and Objective: Hepatitis delta virus is an imperfect virus with RNA and its activity depends on the presence of hepatitis B virus. This virus can lead to acute and chronic diseases in the liver. This study aimed to detect the hepatitis delta virus in blood donors with positive Hepatitis B Surface Antigens (HBsAg). Material and Methods: In this Study, 350 serum sa...
background viral hepatitis is a systemic infection affecting the liver predominantly. almost all cases of acute viral hepatitis are caused by one of five viral agents: hav, hbv, hcv, hdv and hev. the present study aimed to find out the frequency of various forms of viral hepatitis (hav, hbv, and hcv), route of transmission, the history of vaccination against hepatitis b, and clinical findings i...
conclusions elevated aminotransferases in chb patients are most commonly caused by exacerbation of chb. nevertheless, when hbv dna is not elevated, other reasons should be excluded. amongst others, superinfection with another hepatotropic virus can be the reason for decompensation of chronic hepatitis b. this case report describes an asymptomatic hev superinfection followed by a flare in hbv re...
Background & Aim: HBV is hepatotrophic virus that usually causes infection without any symptoms and it is a very important infective factor in patients with acute lymphoblastic leukemia because they need blood products during their treatment. Because of the importance of this subject the aim of this study was to use hepatitis B virus vaccination in patients who did not have immunity for thi...
Background and purpose: Acute viral hepatitis is one of the world's health problems today. An outbreak of hepatitis A virus occurred in a rural area in Mazandaran province, north of Iran, 2019. This research aimed at examining this outbreak in detail in order to study the epidemiological and economic burden, and the possible source of pollution. Materials and methods: This descriptive case...
abstract background: hepatitis b virus infection is an important cause of liver morbidity and mortality worldwide. hdv changes the natural course of hbv. the prevalence of hdv infection wasn’t determined in the various groups of hbv infection (carriers, acute hepatitis, chronic hepatitis, cirrhosis and hcc) in iran. we aimed to research the prevalence of hepatitis d virus infection in various...
conclusions fulminant hepatitis b is associated with distinct mutational patterns of hbv, underlining that genomic diversity of the virus is an important factor determining its pathogenicity. results the most commonly detected diversities affect regulatory motifs of hbv in the core and s region, indicating that these alterations may convert the virus to an aggressive strain. moreover, mutations...
Viral hepatitis is one of five infectional factors cause early death in all over the world. Every day at least one million people die because of viral hepatitis. Six hepatitis viruses have been known until now. They are A, B, C, D, E, G, and it is probable that at least two other kinds i.e. F, and H, will be known soon. Only hepatitis B is a DNA virus, and the others are RNA viruses. All viruse...
