Introduction: Assessing the histological character liver fibrosis by transient hepatic elastography (TE) by Fibroscan has several advantages when compared with liver biopsy and can indicate repeatedly; therefore it can help us to follow up the treatment of chronic hepatitis B. This study is aimed at assessing the biochemical, viral and liver elasticity responses in patients with chronic hepatitis B after 12 months of entecavir treatment. Methods: Prospective, open, non-controlled study. 75 patients over 16 years old were diagnosed with chronic hepatitis B and treated with Entecavir 0.5 mg orally 2 hours after meal during 12 months. Using Fibroscan to assess the liver fibrosis according to the METAVIR classification. Results: ALT decreased rapidly after 3 months of treatment. There were differences in ALT at baseline, compared with ALT at 3 months, 6 months and 12 months (p < 0.05). HBV-DNA responsed below detection thredsold is 32%, 54.7% and 84% after 3, 6, 12 months of treatment, respectively (p<0.05). The change in the Fibroscan value > 1KPa at 6 months was 53.3% after treatment, and this was lower than this proportion at 12 months (61.3%) (p<0.001). Conclusion: Fibroscan may be used as a mean to monitor the responses to HBV treatment besides the biochemical and viral responses. Key words: Chronic B hepatitis, Entecavir, Elastography, Fibroscan

Abstract Background Accurate assessment of liver fibrosis is important to identify patients with chronic hepatitis B (CHB) who require antiviral therapy. As liver biopsy is invasive and costly, non-invasive tests of liver fibrosis are increasingly being used. Aims We aimed to evaluate the performance of the aspartate aminotransferase-to-platelet ratio index (APRI), Fibrosis 4 index (FIB-4), and transient elastography (TE) in predicting fibrosis in patients with CHB. Methods We retrospectively analyzed a prospectively enrolled cohort of consecutive adults with CHB who underwent liver biopsy for routine clinical indications (ALT &gt; ULN and HBV DNA &gt; 2,000 IU/ml) from January 2018 to December 2019. Demographic information, routine biochemistry, HBV serology including HBV DNA, abdominal ultrasound, fibrosis stage by liver biopsy and TE data were collected. Positive predictive values (PPV) and negative predictive values (NPV) were calculated using published cut-off values with liver biopsy as the reference standard. Results Fifty-five patients of Asian ethnicity (mean age 46 years, 65% male) were included. Most patients were HBeAg-negative (67%) and treatment-naïve (80%). Eleven (20%) patients had advanced fibrosis (F3-F4 METAVIR) and 4 (7%) patients had cirrhosis (F4). APRI &lt;0.50 had a NPV of 73% for significant fibrosis (F2-F4) and APRI &gt;1.50 had a PPV of 33% for significant. All 4 patients with cirrhosis were misclassified as having no cirrhosis with an APRI &lt;1. FIB-4 &lt;1.45 had a NPV of 90% for advanced fibrosis (F3-F4). No patient, including 11 patients with advanced fibrosis, had a FIB-4 above the cut-off value to detect advanced fibrosis (&gt;3.25). TE data was available for 38 patients. TE &lt;7.25 kPa had a NPV of 78% for significant fibrosis and TE &gt;12.4 kPa had a PPV of 50% for cirrhosis. Conclusions In Asian patients with CHB and a low prevalence of advanced fibrosis or cirrhosis, APRI, FIB-4, and TE performed well in excluding those with advanced fibrosis but were unable to accurately identify those with significant/advanced fibrosis and cirrhosis. Further studies with larger numbers of CHB patients are needed to confirm our results. Funding Agencies None

BACKGROUND: Liver biopsy for evaluation of liver fibrosis has several adverse effects, for which reason noninvasive tests have been developed.AIM: To evaluate the usefulness of noninvasive biomarkers, qHBsAg and HBV DNA levels in predicting liver fibrosis in patients with hepatitis Be antigen (HBeAg) negative chronic hepatitis B (CHB).MATERIAL AND METHODS: This prospective study included 50 patients with HBeAg negative CHB. All patients underwent laboratory and serology testing, quantification of HBV DNA and HBs antigen. The liver stiffness was measured with elastography. The patients were analysed for APRI and FIB-4, quantitative hepatitis Bs antigen and HBV DNA.RESULTS: Logistic regression analysis showed that greatest significance in predicting liver fibrosis has FIB-4 (Wald = 3.24, P = 0.07), followed by HBV DNA ≥ 2 000 IU/ml ≤ 20 000 IU/ml (Wald = 2.86, P = 0.09), qHBsAg (Wald = 2.17, P = 0.14), HBV DNA > 20 000 IU/ml (Wald = 0.58, P = 0.45), APRI (Wald = 0.04, P = 0.84).CONCLUSION: the FIB-4 index has the greatest value in predicting liver fibrosis while APRI has the lowest; the more advanced liver disease is associated with lower serum level of quantitative HBs antigen. Combination of noninvasive blood biomarkers and imaging tests can provide better diagnostic accuracy and exclude the need for liver biopsy.

Background & Aims. Assess the clinical utility of the Prati criteria and normal ALT (<40 IU/L) in a cohort of patients with chronic hepatitis B infection (CHB). Methods. Serology, radiology, and histology were obtained in 140 patients with CHB. Results. HBeAg+ group: 7 patients (7/56−12% HBeAg+ group) misclassified as “immunotolerant”, with HBV DNA > 6 log copies/ml and normal ALT, who in fact had moderate/severe fibrosis on liver biopsy. HBeAg− group: 10 patients with normal ALT and moderate/severe fibrosis on liver biopsy; 4 of these patients had >3 log copies/ml HBV DNA levels and 6 patients misclassified as “inactive carriers” with negative HBV DNA levels normal ALT and moderate/severe fibrosis (6/84−7% HBeAg− group). Two male HBeAg+ and three male HBeAg- patients with ALT between 20 and 30 IU/L and moderate/severe fibrosis on liver biopsy would have been further mischaracterised using the Prati criteria for normal ALT. Age and ethnic group were more important predictors of moderate/severe fibrosis in multivariate analysis. Conclusion. HBeAg status, age, ethnic origin with longitudinal assessment of LFTs and viral load should be studied in patients with “normal ALT” at the upper end of normal range (ALT 20–40 IU/L) to appropriately classify patients and identify patients for liver fibrosis assessment to inform treatment decisions.

Abstract Background/Aims: We aimed to describe spontaneous short-term hepatitis B Virus (HBV) DNA level fluctuations and to assess the usefulness of quantitative HBsAg (qHBsAg) in Tunisian patients with HBeAg-negative chronic HBV infection.Patients and methods: We included 174 treatment-naïve patients with chronic HBeAg-negative HBV. A one-year prospective follow-up was carried out with serial determinations of HBV DNA, alanine aminotransferase levels and qHBsAg. Patients were classified into three groups: inactive carriers (G1), patients with HBeAg negative chronic hepatitis B (CHB) (G2) and patients with indeterminate state (G3). For this latter group, a liver biopsy was indicated.Results: Only genotype D was detected. During the follow-up, 21.6% and 19.5% of patients with low initial (<2000 IU/mL) and intermediate viral load (2000-20000 IU/mL), experienced a subsequent increase in their HBV DNA levels above 2000 and 20000 IU/mL, respectively. Significant variations of HBV DNA levels (≥0.5 log10 IU/mL) were observed in 61.1% of patients at 6 months-interval. Among the 174 patients, 89 (51.1%) belonged to G1, 33 (19%) to G2 and 52 (29.9%) to G3. Fourteen patients have undergone liver biopsy, among whom 7 (50%) showed moderate to severe liver disease. Combination of HBV DNA <2000 IU/mL and qHBsAg <832 IU/mL excluded CHB in 98.4% of cases.Conclusions: This study highlights the large short-term HBV DNA fluctuations in Tunisian patients with HBeAg negative chronic HBV of genotype D. HBV DNA < 2000 IU/mL along with qHBsAg < 832 IU/mL excluded CHB in 98.4% of cases. Significant proportion of patients with indeterminate state within genotype D would have HBeAg negative CHB.

Oxidative stress plays a pivotal role in the progression of chronic hepatitis B; however, it is unclear whether the status of blood oxidative stress and antioxidant components differs depending on the degree of hepatic fibrosis. To explore the relationship between oxidative stress/antioxidant capacity and the extent of hepatic fibrosis, fifty-four subjects with liver fibrosis (5.5 ≤ liver stiffness measurement (LSM) score ≤ 16.0 kPa) by chronic hepatitis B virus (HBV) were analyzed. From the analysis of eight kinds of serum oxidative stress/antioxidant profiles and liver fibrosis degrees, the level of total antioxidant capacity (TAC) reflected a negative correlation with the severity of hepatic fibrosis (Pearson correlation, r = −0.35, p = 0.01). Moreover, TAC showed higher sensitivity (73.91%) than the aspartate transaminase (AST) to platelet ratio index (APRI, 56.52%) in the receiver operating characteristic (ROC) curves. Interestingly, the TAC level finely reflected the fibrosis degree in inactive carriers (HBV DNA < 2000 IU/mL), while the APRI did in active carriers (HBV DNA > 2000 IU/mL). In conclusion, TAC is a promising biomarker for evaluating the progression of liver fibrosis in patients with HBV, and this finding may indicate the involvement of TAC-composing factors in the pathogenesis of hepatic fibrosis in chronic HBV carriers.

Background: The quantification of HBsAg provides different and complementary information that helps in determination of the different phases of chronic hepatitis B viral infection, evaluation and follow-up of liver disease progression as well as in treatment individualization.Aim: To evaluate the clinical significance of quantitative HBsAg (qHBsAg) in patients with HBeAg negative chronic hepatitis (CHB) and its correlation with the serum levels of alanine aminotransferase (ALT), quantitative HBV DNA and liver fibrosis.Subjects and Methods: The study included 53 treatment naïve patients with HBeAg negative chronic hepatitis B. All patients underwent complete laboratory and serology testing, quantification of HBV DNA and HBs antigen. The liver stiffness was measured with elastography. Patients’ demographic characteristics, viral and biochemical markers were recorded at one point of time.Results: Correlation analysis between the qHBsAg and ALT showed an significant, positive correlation between the parameters for R=0.42 and p<0.05; there was statistically non-significant positive correlation for R=0.25 and p>0.05 between qHBsAg and HBV DNA. There was a positive correlation between qHBsAg and liver fibrosis for R=0.08 and p>0.05. The serum levels of HBsAg had greater impact on the serum levels of ALT compared to that of HBV DNA for R=0.15 and p>0.05.Conclusion: Patients with higher ALT values and higher liver fibrosis score have higher qHBsAg; qHBsAg can reflect the serum HBV DNA levels.
