This article gives an excerpt of key statements from this position paper.

In March 2025， the American Association for the Study of Liver Diseases published its latest practice statement on metabolic dysfunction-associated steatotic liver disease （MASLD） in children. Compared with previous guidelines， this statement adopts the latest nomenclature and diagnostic criteria for MASLD， emphasizes hepatic steatosis in the presence of at least one cardiovascular metabolic risk factor， and elaborates on the unique epidemiological characteristics， pathophysiological patterns， and natural history of pediatric MASLD. Based on evidence-based medicine， the statement provides comprehensive guidance on the screening， diagnosis， treatment and monitoring of MASLD in children and emphasizes that lifestyle interventions form the cornerstone of treatment， and at present， there are still no drugs approved for the treatment of MASLD in children. This article gives an excerpt of the key recommendations in the practice statement.

Objective:To evaluate the prevalence of hepatitis C virus (HCV) infection among patients attending a comprehensive tertiary hospital in Beijing and to pinpoint the key demographics for anti-HCV screening.Methods:A comprehensive retrospective analysis was undertaken, examining data from 631 424 patients who underwent anti-HCV testing between 2017 and 2023. Testing for anti-HCV was conducted using the Abbott i2000 fully automated chemiluminescent immunoassay analyzer. HCV nucleic acid testing was performed with the Roche Cobas AmpliPrep/Cobas TaqMan 96 fluorescent quantitative PCR system, while HCV genotyping was achieved through sequencing.Results:The positive rate of HCV antibodies demonstrated a gradual decline over the years, decreasing from 1.62% in 2017 to 1.01% in 2023. The overall positive rate stood at 1.36% (8 574/631 424), with a nucleic acid testing rate of 59.24% (5 079/8 574) and a nucleic acid positive rate of 34.28% (1 741/5 079). The majority of anti-HCV positive patients came from the department of hepatology (12.17%), followed by hepatobiliary surgery (3.03%), emergency medicine (1.68%), cardiovascular medicine (1.24%) and ophthalmology clinic (1.23%). Notably, the anti-HCV positive rate was significantly elevated in the ≥40 years old group compared to the <40 years old group, with statistical significance ( χ2=1 892.577, P=0.000). The highest anti-HCV positive rates were observed within the 60-69- and 80-99-years old brackets (both at 1.85%), while the peak HCV RNA positive rate was recorded in the 50-59 years old group (27.08%). Females exhibited a significantly higher positive rate (18.53%) than males (15.75%) ( χ2=8.066, P<0.01). When anti-HCV levels surpassed 9 S/CO, the HCV RNA positive rate was notably high, exceeding 38.97%. Intriguingly, at antibody levels ranging from 15 to 16 S/CO, the HCV RNA positive rate climbed to a maximum of 56.17%. Conclusions:This study has successfully identified the key populations for anti-HCV screening: Patients aged over 40, particularly female patients within the 50-69 age bracket; Patients in hepatology, hepatobiliary surgery, emergency medicine, cardiovascular medicine and ophthalmology departments.

Objective:To explore the predictive value of baseline serum levels of hepatitis B virus (HBV) RNA for HBeAg seroconversion in chronic hepatitis B (CHB) subjects with advanced fibrosis/compensated cirrhosis undergoing tenofovir disoproxil fumarate (TDF) therapy.Methods:A case-control study was conducted on 141 patients with CHB combined with advanced fibrosis/compensated cirrhosis who were treated with TDF and tested at Peking University People′s Hospital from January 2015 to December 2020. Patients were divided into HBeAg seroconversion (16 cases) group and non-seroconversion (59 cases) group based on whether HBeAg seroconversion occurred at 240 weeks after treatment. The patients were divided into HBeAg positive and negative groups at baseline (75 and 66 cases, repectively) and at 12 weeks treatment (61 and 80 cases, repectively). The baseline serum levels of relevant indicators were analyzed. HBV RNA levels were measured at baseline and at 240 weeks after treatment. The correlation between HBV RNA and HBV DNA was analyzed using Pearson correlation analysis, and the predictive value was evaluated using the receiver operating characteristic (ROC) curve.Results:For the 75 HBeAg-positive patients at baseline, 21.3% (16/75) achieved HBeAg seroconversion. The HBV DNA and HBV RNA in the HBeAg-positive group were significantly higher than that in the HBeAg-negative group (all P<0.001). Compared with the non-seroconversion group, the HBeAg seroconversion group had significantly lower baseline serum levels of HBV RNA ( P<0.05). Pearson correlation analysis showed that serum HBV RNA levels were positively correlated with HBV DNA in both baseline and 12 weeks HBeAg-negative group and HBeAg-positive group, respectively (baseline: r=0.718, 0.794, P<0.001; 12 weeks: r=0.689, 0.750, P<0.001). ROC curve showed that baseline levels of HBV RNA could be used as a predictor of HBeAg seroconversion in CHB patients with advanced fibrosis/compensated cirrhosis treated with TDF. The area under curve was 0.781, the sensitivity was 75.0%, and the specificity was 78.0%. Conclusion:Baseline serum levels of HBV RNA has a predictive value for HBeAg seroconversion in CHB patients with advanced fibrosis/compensated cirrhosis treated with TDF.

Hepatitis C virus （HCV） can develop into liver cirrhosis or hepatocellular carcinoma， imposing a heavy burden on the patient’s family and the society. Hepatitis C is one of the major public threats for humans， and eliminating hepatitis C is a common goal of all humans. Direct-acting antiviral agents （DAAs） are currently a relatively safe treatment regimen for hepatitis C that can reach a relatively high cure rate and can target different HCV genotypes， making it possible to eliminate HCV infection. China actively promotes the clinical application of DAAs， accelerates drug approval， improves the accessibility of DAAs， and strengthens population intervention. National Medical Insurance Administration has gradually included DAAs in the national medical insurance directory， providing strong support for eliminating HCV infection. In response to the WHO’s goal of eliminating viral hepatitis as a public health hazard by 2030， China has successively released national strategic plans and action plans in recent years， making significant achievements in HCV infection elimination， forming a joint prevention and control system across multiple sectors of the society， and ultimately achieving the goal of eliminating HCV infection. With a focus on the current status of HCV infection in China and prominent prevention and control strategies， this article analyzes and summarizes the practical process of the prevention， control， and micro-elimination of HCV infection， in order to provide a policy reference for carrying out HCV elimination in China and help to achieve the goal of comprehensive elimination of HCV infection.

Pyroptosis is a newly discovered kind of cell death modality that, due to its association with innate immunity, plays a crucial role in cytolysis and inflammatory cytokine release during host defense against infection. In recent years, studies have shown that pyroptosis plays an important role in the occurrence and development of liver diseases. This article introduces and elaborates on the most recent research progress on pyroptosis in liver diseases based on the morphological features, molecular and pathophysiological mechanisms.

Chronic hepatitis D is a kind of severe viral hepatitis caused by co-infection with hepatitis D virus (HDV) and hepatitis B virus (HBV) or infection with HDV on the ground of HBV infection. Patients with hepatitis D who are infected with HBV often have faster disease progression and a worse prognosis. However, the public and clinicians have always paid little attention to chronic hepatitis D. Coupled with the limitations of detection methods and the absence of a screening system, the HDV screening rate in various regions of the world is at a low level. Consequently, the enthusiasm for screening, diagnosis, and treatment has been further reduced by the inadequate effectiveness of previous treatment methods. In recent years, progress has been made in the research and development of anti-HDV drugs, and a variety of drugs have already entered the clinical trial stage, and some have already been approved for commercialization in specific parts of the world. In this context, the world is also actively exploring effective ways to increase the HDV screening rate. The reflex test model can effectively raise the HDV screening rate and serve as a reference for HDV screening in other countries and regions, as demonstrated by studies conducted in the United Kingdom, France, and Spain, among others. This article will review the detection methods, screening, diagnosis, and treatment current status, as well as the progress in drug research and development, in order to help clinical physicians understand chronic HDV diagnosis and treatment.
