Histopathological evaluation of cirrhosis reversal / 中华肝脏病杂志

A normal liver can develop cirrhosis through long-term and repeated stimulation from various etiologies. Histological manifestations like the collapse of hepatic lobular structure (including microvascular structure) and the formation of pseudolobules can lead to portal hypertension and even decompensated cirrhosis. More and more evidence suggests that effective etiological treatment can not only delay but also reverse the progression of cirrhosis. The mechanism of cirrhosis reversal mainly includes the degradation of extracellular matrix, hepatocyte regeneration, and hepatic lobular remodeling. The "gold standard" for the evaluation of cirrhosis reversal at present is still a liver biopsy. Therefore, the histopathological evaluation of cirrhosis reversal is very important for determining the disease's prognosis, efficacy, and mechanism of exploration.

Interpretation of the essential updates in guidelines for the prevention and treatment of chronic hepatitis B (Version 2022) / 中华肝脏病杂志

Chinese Society of Hepatology and Chinese Society of Infectious Diseases, Chinese Medical Association update the guidelines for the prevention and treatment of chronic hepatitis B (version 2022) in 2022. The latest guidelines recommend more extensive screening and more active antiviral treating for hepatitis B virus infection. This article interprets the essential updates in the guidelines to help deepen understanding and better guide the clinical practice.

Regression of liver fibrosis: evidence and challenges / 中华医学杂志(英文版)

It has been reported that liver fibrosis could be reversed after eliminating liver injuries. This article systematically summarizes the evidence of fibrosis regression based on histology, liver stiffness, and serum biomarkers, and discusses several clinically relevant challenges. Evidence from liver biopsy has been regarded as the gold standard in the assessment of fibrosis regression. Semi-quantitative staging and grading systems are traditionally and routinely used to define regression. Recently, the predominantly regressive, indeterminate, and predominantly progressive score was proposed, based on the regressive features from "hepatic repair complex", to provide additional information regarding the quality of fibrosis. For non-invasive assessment, although liver stiffness and serum biomarkers could be applied to reflect the dynamic changes of liver fibrosis, other confounding factors such as liver inflammation have to be considered. In conclusion, both histology and non-invasive methods can provide evidence regarding fibrosis regression. The predictive value of fibrosis regression in long-term prognosis warrants further investigation.

Baseline Hepatitis B Virus DNA Level is a Promising Factor for Predicting the 3 (rd) Month Virological Response to Entecavir Therapy: A Study of Strict Defined Hepatitis B virus Induced Cirrhosis / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Cirrhosis is a common complication of chronic hepatitis B. It remains unclear if viral and biochemical parameters at baseline affect virological response to entecavir and therefore warrant investigation. In the present study, we aimed to evaluate the efficacy of entecavir therapy by monitoring virological response at the end of the 3 rd month of treatment and try to figure out whether baseline factors could help predict it in a cohort of hepatitis B virus (HBV) compensated cirrhosis patients and to determine the cut-off value of a predicting parameter.</p><p><b>METHODS</b>A total of 91 nucleos(t)ide-naïve patients with HBV induced cirrhosis (compensatory stage) were enrolled in a prospective cohort. HBV DNA and alanine aminotransferase (ALT) were tested at baseline and monitored every 3-6 months after starting therapy.</p><p><b>RESULTS</b>Of all 91 patients, the median follow-up time was 12 (9-24) months. Overall, 64 patients (70.3%) achieved virological response in the 3 rd month. Univariate analysis showed that the 3 rd month virological response can be predicted by baseline HBV DNA levels (P < 0.001, odds ratio [OR]: 2.13, 95% confidence interval [CI]: 1.44-3.15), ALT value (P = 0.023, OR: 1.01, 95% CI: 1.00-1.01) and hepatitis B e antigen (HBeAg) negativity (P = 0.016, OR: 0.30, 95% CI: 0.11-0.80). Multiple regression analysis showed baseline HBV DNA level was the only parameter related to full virological response. Higher baseline HBV DNA strata indicated a higher probability that HBV DNA remains detectable at the 3 rd month (P = 0.001). Area under receiver operating characteristic curve for determining the 3 rd month virological response by baseline HBV DNA was 77.6% (95% CI: 66.7-85.2%), with a best cut-off value of 5.8 log 10 .</p><p><b>CONCLUSIONS</b>Baseline HBV DNA, HBeAg negativity, and ALT were independent factors contributing to virological response at the 3 rd month. Further, multiple regression showed that HBV DNA level was the only parameter predicting full virological response as early as the 3 rd month, in this cirrhosis cohort.</p>
