Abstract:

Background: Hepatitis B Virus (HBV) and Human Immunodeficiency Virus (HIV) co-infection in South Africa is estimated between 5-17%; however research determining this prevalence is lacking. With co-infection there is increased risk of liver cirrhosis, end stage liver disease, death as well as higher rates of chronic Hepatitis B infection. Chronic HBV develops in 20% of HIV positive individuals when compared to less than 5% in HIV negative individuals. This also further complicates Highly Active AntiRetroviral Treatment (HAART). Methods: A retrospective observational quantitative, cross-sectio

Thesis (MScMedSc)--Stellenbosch University, 2014.<br>ENGLISH ABSTRACT: Despite the decreased rate of HBV horizontal transmission in South Africa (SA) due to the HB vaccine, the risk of perinatal transmission remains of concern, especially in HIV/HBV co-infected women. Loss of HBV immune control, resulting in higher HBV replication and thus increasing the risk of transmission is described in HIV/HBV co-infected women. Chronic hepatitis is a well-recognized risk factor for hepatocellular carcinoma (HCC). The presence of specific HBV mutations has been reported in chronic and HCC patients and is

Introduction International guidelines endorse the screening of patients for human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV) and Chlamydia trachomatis before assisted reproductive techniques (ART). At present no such guidelines exists in South Africa. At the Reproductive and Endocrine Unit (referred to as “the Unit”) of Steve Biko Academic Hospital, all patients with unknown HIV status are counselled and a blood sample is collected during the initial visit for automated laboratory based HIV screening.

The level of expression of 30 genes was assessed by a real-time reverse transcription-polymerase chain reaction approach at Hep-G2, Huh7 and 4 HBV-positive HCCs. The most informative genes were selected as diagnostic indices. As a result, 9 out of the 30 genes were differentially expressed in HCC. Moreover, 5 out of these 9 genes were eventually selec

Patients with chronic HBV infection are at risk of developing cirrhosis or hepatocellular carcinoma (HCC). Once CHB patients get suitable treatment, the progression to further sequalae could be stopped. The benefits would not be only to the individual, but to the society as a whole.

碩士<br>國立陽明大學<br>臨床醫學研究所<br>102<br>ENGLISH ABSTRACT More than 350 million people are chronically infected with the hepatitis B virus (HBV). Previous reports have indicated that the immune mechanism plays a significant role in the pathogenesis of chronic hepatitis B (CHB). Recently, novel antiviral agents, including pegylated interferon and nucleot(s)ide analogues (NUCs) have been approved in the treatment of CHB. NUCs are effective in suppressing HBV replication, but the rate of achieving hepatitis B e antigen (HBeAg) loss or seroconversion is still unsatisfactory. It would be valuable to de
