Transition rates to cirrhosis and liver cancer by age, gender, disease and treatment status in Asian chronic hepatitis B patients

Objective: Our study aims to detect the sensitivity of the new biomarker miR-212 existing in serum exosomes along with other hepatocellular carcinoma biomarkers such as AFP (alpha-fetoprotein), CA125 (carbohydrate antigen-ca125), and Hbx protein in the diagnosis of HBV-related liver diseases. We also aim to study the roles of these biomarkers in the progression of chronic hepatitis B and provide scientific data to show the clinical value of these biomarkers. Methods: We selected 200 patients with HBV-infection (58 cases of chronic hepatitis B, 47 cases of hepatocellular carcinoma, 30 cases of compensatory phase cirrhosis, and 65 cases of decompensatory phase cirrhosis), 31 patients with primary liver cancer without HBV infection, and 70 healthy individuals as the control group. The expression level of serum AFP and CA125 was detected with electrochemiluminescence immunoassay. The expression level of the Hbx protein was detected with ELISA. Meanwhile, the expression level of miR-212 in serum was analyzed with RT-qPCR. We collected patients’ clinical information following the Child-Pugh classification and MELD score criterion, and statistical analysis was made between the expression level of miR-212 and the collected clinical indexes. Lastly, we predicted the target genes of the miR-212 and its functions using bioinformatics methods such as cluster analysis and survival prediction. Results: Compared to the control group, the expression level of miR-212 in HBV infected patients was remarkably increased (P<0.05), especially between the HBV-infection Hepatocellular carcinoma group and the non-HBVinfection liver cancer group (P<0.05). The expression of miR-212 was increased in patients’ Child-Pugh classification, MELD score, and TNM staging. Moreover, the sensitivity and specificity of miR-212 were superior to AFP, CA125, and HBx protein. Conclusion: There is a linear relationship between disease progression and expression level of miR-212 in the serum of HBV infected patients. This demonstrates that miR-212 plays a significant role in liver diseases. miR-212 is expected to be a new biomarker used for the diagnosis and assessment of patients with HBV-infection-related liver diseases.

Indigenous Australians are disproportionally affected by hepatitis B compared with non-Indigenous Australians. The higher prevalence of hepatitis B among Indigenous Australians has been linked to an increased incidence of liver cancer in this population. There is evidence that comprehensive programs of hepatitis B virus management, which include liver cancer surveillance and appropriate antiviral therapy, offer a cost-effective approach to reduce the incidence of liver cancer in Australia. This paper reports on data from the first study investigating understandings of hepatitis B and attitudes to treatment among Torres Strait Islanders living with chronic hepatitis B. Forty-two participants completed an interview questionnaire. Participants typically had an unclear understanding of hepatitis B and reported significant gaps in monitoring and follow up. A majority of participants indicated a willingness to use treatment if required. The findings of this study suggest the need for a new service delivery model that is appropriate to remote communities such as the Torres Strait Islands, to improve hepatitis B follow up, disease monitoring and management, and where appropriate, the uptake of treatment.
