Background and Objectives: Immune deficiency syndrome is an epidemic disease. During immunodeficiency caused by HIV, infections such as tuberculosis, hepatitis B and hepatitis C may occur. Given that the transmission of these infections is similar to that of HIV, the risk of HIV infection with these infections is high. The purpose of this study was to determine the prevalence of common HIV infe...
Hepatitis B and C viruses are major public health problems. These viruses can chronically lead to liver disease such as fibrosis, cirrhosis, and hepatocellular carcinoma, which often increase mortality in these patients. According to previous studies, the liver is highly affected by changes in the microbiota of gastrointestinal tract and immune system damage caused by inflammation due to viral ...
background occult hepatitis b virus infection (obi) is defined as the presence of hepatitis b virus (hbv) dna in the liver and/or in the serum of patients with negative results of hepatitis b s antigen (hbsag) test with or without serological markers of previous viral exposure. the impact of obi in patients with chronic hepatitis c (chc) is still unclear. objectives the aim of this study was to...
background: in patients with hepatitis b and c, environmental factors such as smoking and alcohol can cause liver fibrosis progression. but opium effects on liver fibrosis progression are not clear. this study was designed to assess the relationship of opium user and liver fibrosis progression. methods: in this case-control study, sixty patients in hepatitis b group and sixty patients in hepati...
