Background and Aims: The predominantly progressive, indeterminate, and predominantly regressive (P-I-R) classification extends beyond staging and provides information on dynamic changes of liver fibrosis. However, the prognostic implication of P-I-R classification is not elucidated. Therefore, in the present research, we investigated the utility of P-I-R classification in predicting the on-treatment clinical outcomes., Approach and Results: In an extension study on a randomized controlled trial, we originally enrolled 1000 patients with chronic hepatitis B and biopsy-proven histological significant fibrosis, and treated them for more than 7 years with entecavir-based therapy. Among the 727 patients with a second biopsy at treatment week 72, we compared P-I-R classification and Ishak score changes in 646 patients with adequate liver sections for the histological evaluation. Progressive, indeterminate, and regressive cases were observed in 70%, 17%, and 13% of patients before treatments and 20%, 14%, and 64% after 72-week treatment, respectively, which could further differentiate the histological outcomes of patients with stable Ishak scores. The 7-year cumulative incidence of HCC was 1.5% for the regressive cases, 4.3% for the indeterminate cases, and 22.8% for the progressive cases ( p <0.001). After adjusting for age, treatment regimen, platelet counts, cirrhosis, Ishak fibrosis score changes, and Laennec staging, the posttreatment progressive had a HR of 17.77 (vs. posttreatment regressive; 95% CI: 5.55-56.88) for the incidence of liver-related events (decompensation, HCC, and death/liver transplantation)., Conclusions: The P-I-R classification can be a meaningful complement to the Ishak fibrosis score not only in evaluating the histological changes but also in predicting the clinical outcomes., (Copyright © 2023 The Author(s).

Background & Aims: Chronic hepatitis B (CHB) and liver fibrosis are associated with a high risk of hepatocellular carcinoma (HCC) development. We assessed whether entecavir (ETV) plus Biejia-Ruangan compound (BRC), an anti-fibrotic traditional Chinese medicine, can further reduce the risk of HCC in treatment-naïve Chinese patients with CHB and an Ishak fibrosis score of ≥3 points derived from our parent double-blind randomized placebo-controlled trial., Methods: After a 72-week comparison between ETV+BRC and ETV+placebo treatment, participants were eligible to enter an open-label treatment phase and were followed up every 6 months. The primary [secondary] endpoints were the incidence of HCC [liver-related deaths, non-HCC events, and non-liver-related deaths]. Modified intention-to-treat (mITT), intention-to-treat (ITT), and per-protocol (PP) populations were defined for the time-to-event analysis., Results: A total of 1,000 patients were recruited; the median age was 42.0 years; 69.9% were male and 58.3% were HBeAg positive. In the mITT population, the 7-year cumulative incidence of HCC [liver-related deaths] was 4.7% [0.2%] for ETV+BRC, which was significantly lower than 9.3% [2.2%] for ETV monotherapy (p = 0.008 [p = 0.030]). Notably, ETV+BRC treatment yielded a lower incidence of HCC in those who did not achieve regression of fibrosis at week 72 than ETV monotherapy (p = 0.018). There were no differences in the other 2 secondary endpoints or safety profiles between the groups. Multivariable Cox proportional regression analysis, including the treatment allocation as a parameter, also demonstrated that ETV+BRC treatment was associated with a reduced incidence of HCC. The ITT and PP analyses showed consistent results., Conclusions: ETV plus BRC combination treatment could further reduce the risk of HCC and liver-related deaths in patients with CHB and advanced fibrosis or cirrhosis, which may have important clinical implications for HCC prevention., Lay Summary: Patients with chronic hepatitis B virus infection are at an increased risk of developing liver cancer (specifically hepatocellular carcinoma [HCC]). While there are effective antiviral treatments that can suppress the virus in chronically infected patients, the risk of HCC remains. Herein, we show that adding a traditional Chinese medicine called Biejia-Ruangan compound to an antiviral reduced the risk of HCC in patients with chronic hepatitis B., Competing Interests: Conflict of interest The authors declare no conflicts of interest that pertain to this work.

Introduction: Little reliable evidence has been reported regarding usefulness of liver stiffness measurement (LSM) for monitoring the hepatic fibrosis changes during treatment. We aimed to assess the association between changes in LSM and histological outcomes in patients with chronic hepatitis B., Methods: In this prospective multicenter study, 727 treatment-naive patients receiving entecavir-based therapy, who underwent paired biopsies at treatment baseline and week 72, were analyzed. Changes in LSM were defined as ≥30% decrease, minor change, and ≥30% increase. Multivariate logistic regression was used to estimate odds ratios (ORs) of changes in LSM on clinical outcomes accounting for regression to the mean. A new on-treatment LSM threshold was established by receiver operating curve., Results: Overall regression of fibrosis, improvement of inflammation, significant histological response, virologic response, alanine aminotransferase normalization, and hepatitis B e antigen seroconversion were 51.2%, 74.4%, 22.0%, 86.0%, 83.5%, and 13.3%, respectively. The association between changes in LSM and improvement of inflammation was nonlinear (P = 0.012). LSM decrease ≥30% was associated with regression of fibrosis (OR 1.501, 95% confidence interval [CI] 1.073-2.099, P = 0.018), significant histological response (OR 1.726, 95% CI 1.124-2.652, P = 0.013), and alanine aminotransferase normalization (OR 2.149, 95% CI 1.229-3.757, P = 0.007). After adjusting for regression to the mean, LSM increase ≥30% became negatively associated with the above 3 outcomes. A new on-treatment LSM cutoff value of 5.4 kPa was established for indicating the significant histological response., Discussion: Changes in LSM are unreliable to estimate regression of fibrosis during treatment; the established cutoff value of on-treatment LSM can optimize monitoring strategy for histological outcomes in patients with chronic hepatitis B., (Copyright © 2021 The Author(s).

Background: HBeAg-positive chronic infection is a unique phase of chronic hepatitis B virus (HBV) infection. Current guidelines advise against starting antiviral treatment for HBeAg-positive chronic hepatitis B virus (HBV) infection patients, some data suggest treating such patients may reduce the risk of hepatocellular carcinoma. We aimed to explore whether these patients can have evident histological liver injury (EHLI), and develop a non-invasive model for identifying EHLI in such patients., Method: We assessed whether HBeAg-positive chronic HBV infection patients can have EHLI defined by Ishak fibrosis stage ≥3 and/or histologic activity index ≥ 9 in a prospective multicenter study. Logistic and Lasso regression was used to select the optimal predictors. We used Akaike information criterion, discrimination improvement, net reclassification improvement to develop and validate models predicting EHLI risk in training cohort and two external validation cohorts., Findings: Of these 336 patients met the inclusion criteria, 181(54%) were HBeAg-positive chronic HBV infection, of whom 60 patients (33%) had EHLI, the proportion of significant fibrosis was higher than that of significant inflammation (33% vs. 8%, P < 0.001). Age, liver stiffness measurement, ALT, alkaline phosphatase, and albumin were identified as independent predictors for EHLI and used to develop a nomogram that have been demonstrated having a good performance in predicting EHLI with AUROCs of 0.92(95%CI: 0.86-0.99) in the training cohort (n = 233) and 0.90(95%CI: 0.84-0.95) in validation cohort 1(n = 103), significant correcting current guidelines recommendations overestimating insignificant or significant histological disease. After 72-weeks entecavir treatment for HBeAg-positive chronic HBV infection patients with EHLI identified by nomogram, histological improvement occurred in 40 of 49(82%), 38(78%) had fibrosis reversal, and 35(73%) no longer had EHLI., Interpretation: In HBeAg-positive chronic HBV infection patients, 33% has EHLI. The nomogram developed in this study can accurately identify HBeAg-positive chronic HBV infection patients with EHLI, and that responded very well to antiviral therapy., Funding: This study was funded by the State Key Projects Specialized on Infectious Disease, Chinese Ministry of science and technology (2013ZX10005002; 2018ZX10725506), National Natural Science Foundation of China (81970525) and Beijing Key Research Project of Special Clinical Application (Z151100004015221)., Competing Interests: Declaration of Competing Interest The authors declare no conflicts of interest., (Copyright © 2021 The Authors.

Objective: Patients diagnosed with hepatitis B virus (HBV)-related hepatic cirrhosis have the potential for progression to hepatocellular carcinoma (HCC) even while undergoing long-term nucleos(t)ide analog (NA) therapy. This study investigated the predictors for the progression of hepatic cirrhosis to HCC under long-term NA therapy., Methods: This retrospective study enrolled 898 patients diagnosed with HBV-related hepatic cirrhosis. They received NA therapy between January 2012 and January 2015. The values for the liver stiffness measurement (LSM), laboratory tests, and disease history were collected. The diagnostic specificity of the serum, was assessed with a receiver operating characteristic curve., Results: The overall 2- and 3-year cumulative incidence of HCC was 6.8% and 15.15%, respectively. The LSM values were higher in the patients who had progressed to HCC. The serum PIVKA-II levels were more efficient than the serum AFP levels for the diagnosis of early HCC as the larger area under curve (0.866 vs. 0.687). The multivariate logistic regression analysis showed that HCC occurrence was significantly associated with the baseline LSM value (odds ratio = 1.035). At the end of the study, the death rate for the patients with larger LSM values was higher than that for those with lower LSM values (67.88% vs. 39.90%)., Conclusion: Patients with HBV-related cirrhosis have the potential for progression to HCC even under long-term NA therapy. The LSM value and the serum PIVKA-II level are significant predictors of HCC occurrence.

Objectives: Chronic hepatitis B (CHB) can progress into liver fibrosis and cirrhosis with poor outcomes. Early and accurate diagnosis of liver fibrosis/cirrhosis is important to guide the preventive strategy of their related complications., Methods: A Chinese multicenter cross-sectional study was conducted to develop and validate a novel noninvasive program for staging liver fibrosis in untreated patients with CHB. Liver histology was evaluated independently by 2 pathologists. The alanine aminotransferase ratio, Hepascore, and aspartate aminotransferase to platelet index values were calculated. Liver stiffness measurement (LSM) and diameter of the spleen were measured. Logistic regression with ℓ1 penalty of regression coefficients was used to select the optimal predictors. The diagnostic accuracy for the stage of liver fibrosis was assessed by the area under the receiver operator characteristic curve with 95% confidence interval (CI)., Results: A total of 1,200 patients with CHB were included, of whom 800 and 400 were in training and validation sets, respectively. LSM, platelets, age, hyaluronic acid, and diameter of the spleen were the top 5 predictors associated with any stage of liver fibrosis and integrated into a novel noninvasive program, named as the Chin-CHB score. The area under the receiver operator characteristic curve of the Chin-CHB score was 0.893 (95% CI: 0.77-0.92) for diagnosing significant fibrosis, 0.897 (95% CI: 0.85-0.95) for advanced fibrosis, and 0.909 (95% CI: 0.87-0.95) for cirrhosis. The diagnostic performance of the Chin-CHB score was similar between training and validation sets. The Chin-CHB score had better diagnostic performance than aspartate aminotransferase to platelet index, alanine aminotransferase ratio, LSM alone, and Hepascore for diagnosing any stage of liver fibrosis., Conclusions: The Chin-CHB score had good diagnostic performance for any stage of liver fibrosis.

Background: Chronic hepatitis B (CHB) can progress to cirrhosis, hepatocellular carcinoma (HCC) and ultimately liver-related death. Although oral antiviral therapy for patients with CHB reduces the risk of such complications, once cirrhosis is established, the benefits of antiviral therapy are not robustly demonstrated. According to traditional Chinese medicine (TCM), some Chinese herbal medicines promote blood circulation and soften hard masses, and therefore they may block and reverse hepatic fibrosis. The aim of this study is to evaluate the effects of TCM tablets of the compound biejia ruangan (RGT) administered for fibrosis, and entecavir (ETV), on the development of HCC in patients with CHB or hepatitis B virus (HBV)-related compensated cirrhosis., Methods/design: This multicenter, centrally randomized, double-blind, placebo-controlled, parallel-group study is planned to complete within 5 years. For the study, 1,000 with CHB or HBV-related compensated cirrhosis are randomly assigned in a 1:1 ratio to a treatment group (0.5 mg ETV once daily; 2 g RGT three times daily) or a control group (0.5 mg ETV once daily; 2 g RGT dummy agent three times daily). The primary end points are the development of HCC and liver-related death. Secondary end points include disease progression and overall survival., Discussion: Although antiviral therapy can achieve sustained suppression of HBV replication, thereby preventing cirrhosis, patients with CHB treated with nucleos(t)ide analogs (NUCs) retain a higher risk for HCC compared with patients with inactive disease. Although previous clinical trials with RGT have confirmed the efficacy of blocking and reversing hepatic fibrosis in patients with CHB or compensated cirrhosis, the long-term risk for HCC or disease progression in these patients treated with combination of RGT and NUCs compared with NUCs alone is unclear. Therefore, it is necessary to investigate the effects of the RGT blockade and reversal of hepatic fibrosis on the development of HCC in patients with CHB or HBV-related compensated cirrhosis in large, prospective, multicenter, double-blind, randomized, controlled trials in China., Trial Registration: ClinicalTrials.gov Identifier: NCT01965418.
