زمینه و اهداف: عفونت های ناشی از هپاتیت B و HIV از جمله معضلات بهداشت جهانی هستند. حدود 10 % از افراد حامل ویروس HIV همزمان مبتلا به‌عفونت هپاتیت B نیز می‌باشند که جمعیتی حدود 4 میلیون نفر را در جهان شامل می‌شوند. در این مطالعه، به‌تعیین فراوانی ژنوتایپ و ساب‌تایپ HBV در بیماران ایرانی دچار عفونت همزمان HIV/HBV و بیماران مبتلا به‌بیماری هپاتیت B به‌تنهایی پرداخته شد. روش بررسی: سرم 58 بیمار...
Hepatitis B virus (HBV) diversity has not been previously studied in Cape Verde. The archipelago was discovered in 1460 by Portuguese explorers, who brought African slaves to colonise the islands. In this study, we investigated the HBV characteristics from 183 HBsAg-positive Cape Verdean individuals. Phylogenetic analysis of the pre-S/S region and the full-length genomes revealed 54 isolates wi...
Hepatitis B Virus (HBV) infection is a major health problem in the developing countries counting Pakistan. This study aimed to examine causes and molecular prevalence of HBV district Bannu Khyber Pakhtunkhwa province,
Background: Hepatitis B surface antigen (HBsAg) is one of the main proteins of HBV envelop and its serum quantitative measurement is the most common quantitative test for monitoring the progress of Chronic Hepatitis B. Although measurement of serum HBV DNA copy number is a gold standard method for displaying viral load, the test is relatively expensive and it is not readily available everywhere...
Aims: Healthy gut microbiome plays a crucial role in the treatment of Hepatitis B Virus (HBV) infection and chronic liver disease. Based on existing studies, we aimed to explore difference efficacy Fecal Microbiota Transplantation (FMT) patients with different stages HBV-related Methods: In this study, 10 HBV HBeAg-negative infection, 8 Chronic (CHB) hepatitis cirrhosis Child-Pugh score A, 9 B/...
The presence of hepatitis B virus (HBV) covalently closed circular DNA (cccDNA) and the permanent integration of HBV DNA into the host genome confers the risk of viral reactivation and hepatocellular carcinoma. Nucleoside/nucleotide analogs alone have little or no capacity to eliminate replicative HBV templates consisting of cccDNA or integrated HBV DNA. Recently, CRISPR/Cas9 technology has bee...
Hepatitis B virus (HBV) barely induces host interferon (IFN)-stimulated genes (ISGs), which allows efficient HBV replication in the immortalized mouse hepatocytes as per human hepatocytes. Here we found that transfection of Isg20 plasmid robustly inhibits the HBV replication in HBV-infected hepatocytes irrespective of IRF3 or IFN promoter activation. Transfection of Isg20 is thus effective to e...
The CRISPR/Cas9 system is a novel genome editing technology which has been successfully used to inhibit HBV replication. Here, we described a novel gRNA-microRNA (miRNA)-gRNA ternary cassette driven by a single U6 promoter. With an anti-HBV pri-miR31 mimic integrated between two HBV-specific gRNAs, both gRNAs could be separated from the long transcript of gRNA-miR-HBV-gRNA ternary cassette thro...
چکیده: زمینه و هدف: اعتیاد تزریقی یکی از مهمترین عوامل خطر برای عفونت هپاتیت ویروسی و ویروس نقص ایمنی انسانی (Human Immunodoficiency Virus=HIV) می باشد. مطالعه حاضر برای تعیین میزان شیوع سرمی هپاتیت C (HCV) و B (HBV) و HIV در معتادان تزریقی و همچنین بررسی برخی عوامل خطر در این گروه انجام شد. روش بررسی: این مطالعه در سال 1383 در شهرکرد به صورت توصیفی - تحلیلی انجام شد. تعداد 133 نفر از معتادا...
BACKGROUND Hepatitis B virus (HBV) genotypes can influence treatment outcome in HBV-monoinfected and human immunodeficiency virus (HIV)/HBV-coinfected patients. Tenofovir disoproxil fumarate (TDF) plays a pivotal role in antiretroviral therapy (ART) of HIV/HBV-coinfected patients. The influence of HBV genotypes on the response to antiviral drugs, particularly TDF, is poorly understood. METHOD...
