abstract background: hepatitis b virus (hbv) infection in patients who lack detectable hepatitis b surface antigen (hbsag) is called occult hepatitis b infection. such infections have been frequently identified in patients with chronic hepatitis cliver disease, but their prevalence is not known. methods: 207 patients with chronic hepatitis c who were hcv -rna and antihcv positive were studied f...

results the results of this study indicated that the overall hepatitis b vaccine acceptance rate was acceptably high. among all, 53.5% correctly identified that a vaccine to prevent hepatitis b virus infection had been available, 15% had a negative opinion, and 31.5% were neutral. the rations of all three doses of vaccination were 69.3%. conclusions among the respondents, 87% were currently mar...

today, chronic viral hepatitis is considered as a public health problem in the world. totally, 5% of the world population, especially in asia and africa suffer from this problem. the prevalence of acute hepatitis in america is 0.1-0.2 percent, 50% of those with hepatitis c (hcv) and 5-10% of them with hepatitis b (hcv) develop chronic hepatitis. determining hbv and hcv genotypes is important to...

Background: Hemophilia A and B are the most frequent congenital coagulation disorders. This study was conducted to determine the prevalence of hepatitis B, C and human immunodeficiency viruses among hemophilic patients in Hamadan, Iran. Patients and Methods: In this study, patients with hemophilia A and B treated in Hamedan Hemophilia Center, Hamedan, Iran, were screened for hepatitis B, C and...

BACKGROUND Since the introduction of Highly Active Anti-Retroviral Therapy and the dramatic improvement in the prognosis of individuals with Human Immunodeficiency Virus, liver disease due to chronic viral hepatitis has become as important cause of morbidity and mortality in co-infected individuals. The objective of the study was to determine the Sero-prevalence of Hepatitis B Virus, Hepatitis ...

Background: Scleroderma is a chronic systemic disorder that affects the connective tissues. It is characterized by several immune manifestations, inflammation, vascular damage, and fibrosis. Some of the viral infections with complex mechanisms are involved in the development and progression of many autoimmune diseases, such as scleroderma. The present study aimed to investigate the serological ...

conclusions overall, we found that obi was rare, but that the prevalence of obi was slightly higher in jiangsu than in other areas of china. methods all donor samples were routinely screened by double enzyme-linked immunosorbent assay (elisa) for hepatitis c virus (hcv), hepatitis b virus (hbv), human immunodeficiency virus (hiv), treponema pallidum (tp), and alanine aminotransferase (alt). sin...

background hepatitis b is the most common chronic viral infection in humans and the most common cause of death among viral hepatitis. as 70% to 80% of chronic hepatitis cases are caused by hbv in iran, this virus alone is considered the most important cause of liver diseases and the major cause of mortality arising from viral hepatitis cases in iran. objectives we planned this study to determin...

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...
