introduction: tt virus (ttv) is an unenveloped single-stranded circular dna virus. sensitive pcr (polymerase chain reaction) methods with primers designed for very conserved regions of the viral genome (utr) indicate high prevalence (> 90%) of ttv infection in general population of many countries world-wide. although there has been no evidence of its relation to any liver or other specific dise...

OBJECTIVES To evaluate the current seroprevalence of antibodies against hepatitis A virus (HAV) in a sample of schoolchildren above 10 years of age and to determine the prevalence of HAV-induced hepatitis in adults at a tertiary care hospital in northern India between January 1992 and December 2000. METHODS Sera from 276 male and 224 female schoolchildren aged 10-17 years were tested for anti...

background hepatitis delta virus (hdv) is dependent on the hepatitis b virus for transmission and propagation. based on isolated hdv sequences from different parts of the world, at least three major different genotypes with different geographic distributions are suggested. studies have shown that genotype 1 is the predominant genotype of hdv in different parts of iran; however, the genotype dis...

conclusions although hdv had low prevalence in our area, it is vital to plan preventive strategies for hdv spread as well as hbv prevention. it is particularly important to suspect hdv infection in active hbv carriers to manage a particularly severe dual infection. hdv infection should be suspected even in negative hbsag patients having “isolated anti-hbc” profile. results prevalence of hdv was...

one of the most serious kinds of hepatitis is hepatitis b. this condition is more common than aids, and is 100 time more contagious. in iran the most common cause of acute and chronic hepatitis, liver cirrhosis, and also hepatocellar carcinoma in adults, is hepatitis b. more than two billion people are infected and more than 350 million of individuals are carriers of this virus in the entire wo...

Hepatitis Delta virus (HDV) is a degenerate RNA virus or virusoid and a satellite of Hepatitis B virus (HBV). Three distinct genotypes are described for HDV; genotype I is distributed worldwide but other genotypes appear to be more restricted geographically. In the present study, an RT-nested PCR method was set up to detect delta infection from serum samples. Moreover, the target amplified sequ...

BACKGROUND Hepatitis B virus (HBV), hepatitis D virus (HDV), and human immunodeficiency virus (HIV) are transmitted by blood transfusion. Thus, hemodialysis (HD) patients are more prone to become the carriers of these infections due to their treatment demands. OBJECTIVES The aim of this study was to assess the prevalence of HBV and HIV infections among HD patients in Bandar Abbas, Iran, 2015....

AIM OF THE STUDY To assess the prevalence and severity of vitamin D insufficiency in patients with hepatitis C virus (HCV) infection and in patients with hepatitis B virus (HBV) infection. MATERIAL AND METHODS This prospective study included 90 patients with chronic hepatitis C and 35 patients with chronic hepatitis B admitted to the Infectious Diseases Department between March 2013 and May 2...
