Tu1478 – Rest-B Study: Liver Fibrosis Regression Assessed by Transient Elastography (TE) in Patients with Chronic Hepatitis B (CHB) on Long Term Maintenance Therapy with Tenofovir Disoproxil Fumarate (TDF)

Abstract Background and aim Mac-2-binding protein glycosylation isomer (M2BPGi) is a novel serum diagnostic marker for liver fibrosis in various liver diseases. We aimed to evaluate its role in assessment of liver fibrosis in chronic hepatitis B infection (CHB) with reference to liver stiffness measurement (LSM) by transient elastography (Fibroscan). Design and Methods A case control study. 50 CHB patients with LSM by transient elastography technology and retrievable serum samples and 20 normal volunteers as a control group were recruited. Results 50 CHB patients (M: F = 30:20; mean age 43years ± 10.58) and 20 normal control volunteers (M: F = 12:8; mean age 37years ± 14.5) were recruited. The mean M2BPGi values for control group, F0-F1, F2, F3 and F4 progressively increased with more advanced stages of liver fibrosis: 0.282, 0.719, 1.322, 1.65 and 1.904 COI, respectively (p < 0.001). M2BPGi levels correlated well with liver stiffness (r = 0.911) and moderately with FIB-4 (r = 0.682), and with APRI (r = 0.536) (all p < 0.001). Using cut-off values of 0.455, 1.02, 1.16, 1.66 and 1.71COI for control, F0-F1, F2, F3 and F4 groups, respectively, the AUROCs were 0.996, 0.996, 0.691, 0.794 and 1.00 for control, F0-F1, F2, F3 and F4 groups, respectively. There was a statistically significant but with weak positive correlation between M2BPGi serum level and INR (r = 0.333, p = 0.018). And there was a statistically significant but with weak negative correlation between M2BPGi serum level and platelet count (r = -0.41, p = 0.003) and HBV DNA (r = -0.373, p = 0.008).There was a statistically significance between M2BPGi serum level and the history of varices (p = 0.023) Conclusions WFA+-M2BP is an accurate serum indicator for assessing different stages of liver fibrosis. WFA+-M2BP provides a simple and reliable alternative or complementary method to liver biopsy and FibroScan.

Abstract The assessment of liver fibrosis in patients with chronic hepatitis B (CHB) is of great importance in evaluating the phases of chronic hepatitis B viral infection, prompt administration of antiviral therapy, prevention of disease progression and late complications of CHB infection. Aim: to investigate the clinical significance of quantitative HBs antigen as a predictor for liver fibrosis in patients with HBe antigen negative chronic hepatitis B and inactive carriers. Material and Methods: the study included 44 treatment naïve patients with chronic hepatitis B, divided into two groups, HBeAg negative chronic HBV infection or inactive carriers (IC) and HBeAg negative chronic hepatitis B patients. All patients underwent laboratory, serologic testing, ultrasound and transient elastography (TE). In both patient groups, quantitative HBs antigen (HBsQ), alanine aminotransferase (ALT), hepatitis B virus deoxyribonucleic acid (HBV DNA) and liver fibrosis were analyzed. Results: The value of HBsQ is significantly higher in patients with HBeAg negative CHB 2477.02±4535.44 IU/ml than in the IC group 8791±11891 IU/ml; Z=3.32, p<0.001 (p=0.0009). In IC patients, 1 (4.76%) had fibrosis and 20 (95.24%)) did not have fibrosis. Out of 23 patients with HBeAg negative chronic hepatitis B, 8 (34.78%) had fibrosis and 15 (65.22%) did not have fibrosis. Patients with HBeAg negative hepatitis B had significantly higher liver fibrosis than IC; Fisher Exact Test p<0.05 (p=0.02). The increase of HBsQ for one single unit (IU/ml) does not have predictive value for fibrosis (Ext (B) =1.00), 95% C.I. for EXP (B): 1.00-1.00 / p>0.05. Conclusion: Quantitative hepatitis B surface antigen has intermediate weak statistically insignificant prediction for liver fibrosis R=0.25 (p<0.10).
