Chronic hepatitis B has highly a dynamic course with significant fluctuations of HBV-DNA and ALT impeding assessment of disease activity. New biomarkers of inflammatory versus noninflammatory stages of HBV infection are urgently needed. Cytokeratin 18 epitope M30 (M30 CK-18) is a sensitive marker of cell death. We aimed to investigate an association between serum M30 CK-18 and histological activity and phase of HBV infection. 150 Caucasian patients with HBV-infection were included in the study. Serum M30 CK-18 levels reflected phase of disease, being significantly higher in both HBeAg(+) and HBeAg(−) hepatitis B in comparison to HBsAg(+) carrier groups. The highest serum M30 CK-18 levels were observed in subjects with the most advanced stages of HBV. Moreover, its serum concentrations correlated with both inflammatory activity and fibrosis advancement (ANOVA P<0.001). Importantly, serum M30 CK-18 levels were able to discriminate patients with mild versus moderate-advanced fibrosis (AUC: 0.86) and mild versus active liver inflammation (AUC: 0.79). M30 CK-18 serum concentration has good sensitivity and specificity in discriminating mild versus moderate/severe fibrosis and inflammation even in patients with normal ALT activity. This study suggests M30 CK-18 as a potential noninvasive marker of disease activity and also a marker of phase of persistent HBV infection.

We have conducted a pilot study to identify the association between the HBsAg level and activity of the pathological process in the liver, as well as possibility of quantitative assessment of HBsAg for monitoring chronic liver diseases caused by hepatitis B virus (HBV) and hepatitis D virus (HDV). Objective. To assess the possibility of using HBsAg levels as a predictor of disease activity and prognosis in patients with chronic HBV infection with delta-agent. Patients and methods. We analyzed serum specimens from 30 patients with HDV and HBV co-infection. Among 15 patients with chronic hepatitis B with delta-agent, there were 5 HBV DNA positive and 10 HBV DNA negative. Among patients with liver cirrhosis, HBV DNA was detected in 11 individuals, while 4 individuals had undetectable HBV DNA levels. Results. We found that mean HBsAg level in patients with chronic HBV infection and negative HBV DNA was 1.9 ± 0.56 IU/mL. Mean HBsAg level in patients with chronic HBV infection with delta-agent and positive HBV DNA was 4.3 ± 0.62 IU/mL (p < 0.05). High HBsAg levels correlated with elevated ALT in patients with chronic hepatitis B and delta-agent. Patients with liver cirrhosis caused by HDV had normal ALT levels, but elevated bilirubin concentrations regardless of HBV DNA presence and HBsAg level. Conclusion. High levels of HBsAg can be considered as a predictor of active disease in patients with chronic HBV infection with delta-agent and also a marker of transformation of chronic hepatitis B with delta-agent into liver cirrhosis. Key words: chronic hepatitis B with delta agent, liver cirrhosis, enzyme-linked immunosorbent assay, HBsAg levels, polymerase chain reaction

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.

Immunity against hepatitis B virus (HBV) infection is complex and not entirely understood so far, including the decisive factors leading to the development of chronic hepatitis B. This lack of a mechanistic understanding of HBV-specific immunity is also caused by a limited number of suitable animal models. Here, we describe the generation of a recombinant adenovirus expressing an HBV 1.3-overlength genome linked to luciferase (Ad-HBV-Luc) allowing for precise analysis of the quantity of infected hepatocytes. This enables sensitive and close-meshed monitoring of HBV-specific CD8 T cells and the onset of anti-viral immunity in mice. A high dose of Ad-HBV-Luc developed into chronic hepatitis B accompanied by dysfunctional CD8 T cells characterized by high expression of PD1 and TOX and low expression of KLRG1 and GzmB. In contrast, a low dose of Ad-HBV-Luc infection resulted in acute hepatitis with CD8 T cell-mediated elimination of HBV-replicating hepatocytes associated with elevated sALT levels and increased numbers of cytotoxic HBV-specific CD8 T cells. Thus, the infectious dose was a critical factor to induce either acute self-limited or chronic HBV infection in mice. Taken together, the new Ad-HBV-Luc vector will allow for highly sensitive and time-resolved analysis of HBV-specific immune responses during acute and chronic infection.

Hepatitis B Virus (HBV) infection can causes spectrum of diseases ranging from clinically asymptomatic state to the development of cirrhosis and hepatocellular carcinoma (HCC). There is ongoing debate in the management of asymptomatic patients with chronic hepatitis B virus (CHBV) infection with high DNA and normal ALT level. It has been recently shown that a significant proportion of patients with CHBV infection with high DNA and normal ALT level have significant histological abnormality. So this study was aimed to see the histological changes in patients with CHBV infection with high DNA and ALT level <2 times of upper limit of normal (ULN). Total 64 patients were included in this cross sectional study. Mean age was 29 years, 55 (85.9%) patients were men. Forty patients (62.5%) were HBeAg positive. Thirty seven (57.8%) patients had normal ALT levels and 27 patients (42.2%) had ALT levels 1-2 x ULN. Out of 64 patients 46.8% had significant histological abnormalities. Among them 31.2% had significant fibrosis and 26.5% had significant necroinflammatory changes. Among 37 patients with normal ALT levels 35% had significant histological abnormalities. But among 27 patients with ALT levels of 1-2 x ULN, 63% had significant histological abnormalities. In this series significant histological abnormalities were found in 40% of HBeAg+ve cases and 58.3% of HBeAg-ve cases. But this difference was not statistically significant. It was also found that patients with significant histological abnormalities were significantly older and had a lower median HBV DNA level, lower mean platelet count, lower mean prothrombin activity ratio and lower mean albumin level than patients with nonsignificant histological changes. In logistic regression analysis it was found that serum ALT levels and age at which patients entered the study were independently associated with the risk for significant histological abnormalities.Faridpur Med.

Thrombocytopenia is a relatively uncommon extra-hepatic manifestation of uncomplicated chronic hepatitis B virus (HBV) infection. This study has two aims: to assess the prevalence of thrombocytopenia in non-cirrhotic patients with chronic hepatitis B (CHB); and to determine the association of certain variables with thrombocytopenia in Duhok province. It is a case control study conducted in Azadi Teaching Hospital during June 2016 - May 2019. Chronic active hepatitis B was defined according to the following parameters: the presence of detectable hepatitis B surface antigen (HBsAg) in the blood longer than six months, positive or negative HBeAg, HBV-DNA level >2000 IU/ml, elevated ALT, and/or at least moderate histopathological fibrosis. Thrombocytopenia was defined as platelet counts below 150,000/μl. The obtained results were analyzed by entering data into Microsoft Excel 2010. A total of 379 CHB patients and 200 cases as control were enrolled in this study. Their mean ages were 33.62 ± 14.48 and 40.72 ± 18.56 for HBV and control cases, respectively. There were 236 (62.27%) males in the HBV patients and 109 (54.50%) males in the control group. Comparing both groups, significant association was found between HBV and younger age, cigarette smoking, and alcohol consumption. Chronic active hepatitis B without liver cirrhosis was strongly associated with an increased rate of thrombocytopenia. This finding is paramount as it is statistically significant (P = 0.042). Significant association with younger age and Syrian nationality was found more in CHB patients with thrombocytopenia compared to non-thrombocytopenic. In conclusion, chronic active hepatitis B is strongly associated with thrombocytopenia. As hypersplenism resulting from liver cirrhosis was excluded in our patients, the cause of thrombocytopenia is due to other mechanisms. Therefore, it is important to consider CHB in the differential diagnosis of patients presenting with isolated thrombocytopenia. Older age and Syrian nationality were predictors for developing thrombocytopenia in chronic active HBV infection. Asian J. Med. Biol. Res. June 2019, 5(3): 207-211
