The Absence of Hepatitis C Virus Infection Among Patients with Hepatitis B virus in Mashhad, Iran

Background and Aims: Many studies have provided evidence for the role of hepatitis B and C viruses in the development of liver cancer. Although the routine treatment is available for both conditions, no definite guideline is available to treat patients dually infected with HBV and HCV. This study was performed to determine the frequency of HBV/HCV-coinfection in Mashhad, North-East of Iran. Mat...

Sequence-based genotyping of hepatitis B virus in general popula-tion

    Background: Hepatitis B Virus (HBV) causes acute and chronic liver disease worldwide. HBV has eight genotypes (A to H) which is the reflection of its genome with their characteristic geographical distribution. Each genotype could have different pathogenic and therapeutic characteristics. There have been few records on HBV genotyping in general population from our region. This study aimed to...

CHARACTERISTICS AND PREVALENCE OF OCCULT HEPATITIS B VIRUS INFECTION IN PATIENTS WITH HEPATITIS C IN IRAN

 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 stu...

Prevalence of Hepatitis B virus, Hepatitis C virus and human immunodeficiency virus infections among patients candidate for orthopedic trauma surgeries

Background: Infectious diseases are major public health problems, among which blood-borne ones are the most important infections. Patients who undergo orthopedic surgery are at higher risk of transmitting infectious diseases from and to others, due to repeated blood examinations and injection, drains secretion and receiving blood products.
