Background and purpose: Hepatitis Delta Virus (HDV) agent, or HDV, is a defective RNA virus that infects with HBV (Hepatitis B Virus). 15 millions people around the world are infected to HDV. There are different statistics in Iran and other countries about HDV incidence, according to accomplished studies. This study was done for determining HDV incidence in sari and considering its correlativ...
Abstract Background Thalassemia patients that are conventionally treated by a regular transfusion regimen are exposed to blood born viral infections.The aim of this study was to investigate the seroprevalence of hepatitis B virus (HBV), hepatitis C virus (HCV) , and human Immunodeficiency virus(HIV) among all multitransfused thalassemia patients in west north of Iran. Material and methods A...
background hepatitis e virus (hev) infection is a self-limited hepatitis and the most common cause of acute adult hepatitis in asia. young adults and middle-aged populations are more likely to be infected than other age groups. objectives the aim of this study was to determine the seroprevalence of anti-hev among injection drug users (idus) compared to non-idus. patients and methods this was a ...
Hepatitis B virus(HBV) is the cause of hepatitis and hepatic cancer. Each year more than 800 thousands die from HBV infection and its complication in the world. More than 350 million people are the career of this virus in the world and careers are the main source of this disease in community. Approximately 3% of Iranians are virus career, but in USA and Western European countries this rate ...
Background and purpose: Viral hepatitis is a systemic infection that mainly affects the liver. We studied the prevalence of skin lesions and infectious diseases including hepatitis A and B virus infection in patients attending Qaemshahr Razi Teaching Hospital, Iran 2013-2015. Materials and methods: In this retrospective descriptive study, records of patients diagnosed with hepatitis were inv...
Hepatitis viruses (HAV, HBV, HCV, HDV and HEV) are attributed to a wide spectrum of acute and chronic liver diseases, including carcinomas. Worldwide, >250 million become chronically infected by HBV and ~150 million by HCV every year. Though, new hepatotropic viruses, such as HGV, GBV, TTV and SENV are identified in chronic liver diseases, thousands still suffer of unknown etiology. Despite a p...
Abstract Background and Objectives Hepatitis C virus is the main cause of hepatitis C infection that usually has no symptoms at early stages. Studies have shown changes in the expression level of microRNAs in various diseases such as hepatitis. MiR-199a and miR-196b have an inhibitory effect on hepatitis C virus. In a recent study, we examined the expression levels of miR-199a and miR-196b in ...
Background & Aims: Hepatitis B infection is a global health problem. Hepatitis B virus can escape from the innate immune system, however adaptive immune system mainly acts against it. Transforming growth factor (TGF-) has three isoforms in mammals. Several studies have recently shown that TGF-1 suppresses replication of hepatitis B virus. Moreover, high expression of this factor is effective in...
Abstract Background: Investigators were suspicious of tyrosine-methionine-aspartate-aspartate (YMDD) mutations occurred only in patients who were treated by lamivudine. However, YMDD mutations of hepatitis B virus gene (HBV DNA) in patients with chronic hepatitis B (CHB) untreated with antiviral medicines was reported in some studies. The aim of this study was to evaluate YMDD mutations in Ira...
Background and Aims: Hepatitis D virus (HDV) can infect human population either as a superinfection or concurrent hepatitis B virus (HBV) infection. It is expected that presence of HDV infection is more prevalent in endemic HBV areas. Overall 5% of Iranian general populations are chronic HBV carriers. The aim of this study was to determine the seroprevalence of HDV and its clinical impact in ...
