The association of vitamin D with hepatitis B virus replication: Bystander rather than offender.

The association of vitamin D with hepatitis B virus replication: Bystander rather than offender. J Formos Med Assoc. 2020 Jan 10;: Authors: Wang CC, Tzeng IS, Su WC, Li CH, Lin HH, Yang CC, Kao JH Abstract BACKGROUND/PURPOSE: Low vitamin D is frequent in hepatitis B virus (HBV)-infected patients and several studies show an inverse association of serum vitamin D level with HBV viral load. However, the causal relationship remains unclear. METHODS: HBV carriers receiving regular 6-month surveillance without current antiviral treatment or cirrhosis were invited to participate into this trial. The markers of HBV replication included serum HBV DNA and quantitative HBsAg (qHBsAg) levels. Those with undetectable HBV DNA or sufficient vitamin D levels, cancer or electrolyte imbalance were excluded. The eligible subjects were randomized to receive either vitamin D supplement 2000 IU per day for 2 months (vitamin D group) or none (control group). RESULTS: A total of 196 HBV carriers (93 males and 103 females; mean age 51.9 ± 10.0 years) were screened. Of them, 28 patients had undetectable serum HBV DNA levels, which is defined as spontaneous viral clearance. The vitamin D levels were not different between patients with detectable HBV DNA and those without (p = 0.18). After exclusion, 149 patients were randomized to two groups: 75 in vitamin D group and 74 in control group. After 2 months vitamin D supplement, the serum vitamin D...

Abstract Primary liver cancer is the third leading cause of cancer-related death worldwide. Most patients are diagnosed at late stages with poor prognosis, thus identification of modifiable risk factors for primary prevention of liver cancer is urgently needed. The well-established risk factors of liver cancer include chronic infection with hepatitis B virus (HBV) or hepatitis C virus (HCV), heavy alcohol consumption, metabolic diseases such as obesity and diabetes, and aflatoxin exposure. However, a large proportion of cancer cases worldwide cannot be explained by current known risk factors. Dietary factors have ...

It turns out that many more people than just boomers can benefit from testing for hepatitis C, a viral infection of the liver that often causes no symptoms. If you’re a member of the baby-boom generation (born between 1946 and 1964), your doctor may have already recommended the test. But those born before or after those years may not have known about the test unless they had a risk factor for hepatitis C, such as a history of intravenous drug use. A new guideline is changing this approach. Why the different recommendations for baby boomers? In 2012–2013, the CDC and the US Preventive Services Task Force (USPSTF...

ConclusionsElderliness, male sex, elevated ALT, AST, NLR, AFP, cirrhosis, HBeAg+, and no ‐antiviral treatment were independent risk factors for HBV‐HCC. AASLD standard of ALT cut‐off value may not be suitable for the Chinese population. Regular monitoring of HCC among HBeAg‐ patients with abnormal AFP may improve the management of HBV ‐HCC. The diagnostic performance of AFP combined with ALT, AST, and NLR for HBV‐HCC was superior to single biomarker or any other combinations among these patients, and its diagnostic equation can be used as useful tool for differentiation of HBV‐HCC from CHB.

This study revealed a distinct mechanism underling the regulation of HBV replication mediated by SOX9. HBV induces SOX9 mRNA and protein expression in human hepatoma cells, including HepG2.2.15, HepG2, Huh7, and HepG2-NTCP cells. Further study demonstrated that HBV activates SOX9 expression at the transcriptional level through inducing SOX9 promoter activity and HBc could induce the activity of SOX9 promoter. Interestingly, SOX9 in turn represses HBV replication in human hepatoma cells. More importantly, SOX9 inhibits HBV infection in HepG2-NTCP cells and C57/BL6 mice. Detailed study revealed that SOX9 suppresses HBV repli...

Abstract DNA methylation is one of the epigenetic mechanisms to regulate gene expression and frequently occurs in human cancer cells. T-cadherin (CDH13) is a new member of the cadherin superfamily and possesses multiple functions. Our study included 26 normal controls (NCs), 65 chronic hepatitis B patients (CHB), 14 liver cirrhosis patients (LC) and 157 hepatocellular carcinoma patients (HCC). We mainly focused on the mRNA expression and methylation status of CDH13 in peripheral blood mononuclear cells (PBMCs), which were detected by semi-quantitative real-time polymerase chain reaction (RT-qPCR) and methylation-s...

n Lee Chen Tyan Hepatocellular carcinoma (HCC) is among the ten most commonly diagnosed cancers and the fourth leading cause of cancer-related death. Patients with hepatitis B virus (HBV) infection are prone to developing chronic liver diseases (i.e., fibrosis and cirrhosis), and the HBV X antigen plays an important role in the development of HCC. The difficulty in detecting HCC at the early stages is one of the main reasons that the death rate approximates the incidence rate. The regulators controlling the downstream liver protein expression from HBV infection are unclear. Mass spectrometric techniques and cu...

ConclusionA substantial further reduction in cases of HCC requires a wider application of universal HBV vaccination and effective treatment of HBV- and HCV-related chronic hepatitis and cirrhosis, more effective campaigns to favor correct dietary habits and reduce alcohol consumption and the intensification of studies on HCC pathogenesis for future optimized prevention strategies.
