    TBX3在癌症中表现为肿瘤抑制因子或癌蛋白。然而,TBX3功能在肝内胆管癌(iCCA)中仍未确定,致命的原发性肝脏恶性肿瘤,几乎没有全身治疗选择。本研究旨在研究TBX3对iCCA的影响。我们发现TBX3的过表达强烈抑制人iCCA细胞生长。在Akt/FBXW7ΔF小鼠iCCA模型中,Tbx3的过表达减少了体内的胆管癌发生,而Tbx3的诱导型基因敲除加速了iCCA的生长。RNA-seq将MAD2L1鉴定为TBX3过表达细胞中的下调基因,和ChIP证实TBX3与MAD2L1启动子结合。CRISPR介导的Mad2l1敲低显著降低了两种iCCA模型在体内的生长。最后,我们发现TBX3在约20%的人iCCA样本中表达上调,它的高表达与较少的增殖和较好的存活率有关。MAD2L1表达在大多数人iCCA样品中上调,并且与TBX3表达负相关。总之,我们的研究结果表明,TBX3的过表达通过抑制MAD2L1的表达来抑制CCA进展.
    TBX3 behaves as a tumor suppressor or oncoprotein across cancer. However, TBX3 function remains undetermined in intrahepatic cholangiocarcinoma (iCCA), a deadly primary liver malignancy with few systemic treatment options. This study sought to investigate the impact of TBX3 on iCCA. We found that overexpression of TBX3 strongly inhibited human iCCA cell growth. In the Akt/FBXW7ΔF mouse iCCA model, overexpression of Tbx3 reduced cholangiocarcinogenesis in vivo, while inducible genetic knockout of Tbx3 accelerated iCCA growth. RNA-seq identified MAD2L1 as a downregulated gene in TBX3-overexpressing cells, and ChIP confirmed that TBX3 binds to the MAD2L1 promoter. CRISPR-mediated knockdown of Mad2l1 significantly reduced the growth of two iCCA models in vivo. Finally, we found that TBX3 expression is upregulated in ~20% of human iCCA samples, and its high expression is associated with less proliferation and better survival. MAD2L1 expression is upregulated in most human iCCA samples and negatively correlated with TBX3 expression. Altogether, our findings suggest that overexpression of TBX3 suppresses CCA progression via repressing MAD2L1 expression.

    目的:慢性丁型肝炎(CHD)是慢性病毒性肝炎的一种严重形式。估计西班牙的HDV患病率约为乙型肝炎患者的5%。新的抗病毒疗法(Bulevirtide,BLV)在我国被推迟到2024年2月。我们的目的是在BLV批准时,描述西班牙HDV/HBV感染患者的临床特征及其管理中的当前障碍。
    方法:多中心登记,包括在30个西班牙中心积极监测的抗HDV血清学阳性患者。流行病学,在随访开始时和最后一次访视时记录临床和病毒学变量.
    结果:我们确定了329名抗HDV患者,41%为女性,平均年龄51岁。最常见的地理起源是西班牙(53%)和东欧(24%)。来自西班牙的患者年龄较大,HCV和HIV合并感染可能与过去的药物注射有关(p<0.01)。HDV-RNA在评估的221个中的138个为阳性(62%)。肝硬化在33%的诊断中存在,并且在病毒血症患者中更常见(58%vs25%,p<0.01)。经过6(3-12)年的中位随访,44(16%)解决了感染(自发18和Peg-INF后26)。另外10%的患者在随访期间发展为肝硬化(n=137)(45%患有门静脉高压症,14%的肝脏代偿失调)。肝脏疾病进展与持续的病毒血症有关。
    结论:三分之一的冠心病患者在诊断时已经患有肝硬化。阳性病毒血症的持续与肝脏疾病的快速进展有关。重要的是,存在局部确定/定量HDV-RNA的障碍。
    OBJECTIVE: Chronic hepatitis D (CHD) is a severe form of chronic viral hepatitis. The estimated HDV prevalence in Spain is around 5% of patients with hepatitis B. Reimbursement of new antiviral therapies (Bulevirtide, BLV) was delayed in our country until February 2024. We aimed to characterize the clinical profile of patients with HDV/HBV infection in Spain and current barriers in their management at the time of BLV approval.
    METHODS: Multicenter registry including patients with positive anti-HDV serology actively monitored in 30 Spanish centers. Epidemiological, clinical and virological variables were recorded at the start of follow-up and at the last visit.
    RESULTS: We identified 329 anti-HDV patients, 41% were female with median age 51 years. The most common geographical origin was Spain (53%) and East Europe (24%). Patients from Spain were older and had HCV and HIV coinfection probably associated to past drug injection (p<0.01). HDV-RNA was positive in 138 of 221 assessed (62%). Liver cirrhosis was present at diagnosis in 33% and it was more frequent among viremic patients (58% vs 25%, p<0.01). After a median follow-up of 6 (3-12) years, 44 (16%) resolved infection (18 spontaneously and 26 after Peg-INF). An additional 10% of patients developed cirrhosis (n=137) during follow-up (45% had portal hypertension and 14% liver decompensation). Liver disease progression was associated to persisting viremia.
    CONCLUSIONS: One-third of the patients with CHD already have cirrhosis at diagnosis. Persistence of positive viremia is associated to rapid liver disease progression. Importantly, barriers to locally determine/quantify HDV-RNA were present.

    慢性肝病(CLD)导致肝细胞损伤,在几种实质和非实质肝细胞类型中引发促炎状态,最终导致肝纤维化,肝硬化,门静脉高压症(PH)和肝功能衰竭。因此,对炎性体-肝损伤的关键分子驱动因素-的进一步理解支持了新型诊断或预后生物标志物和有效治疗方法的开发.在肝脏疾病中,先天免疫细胞通过Toll样受体(TLRs)和核因子κB(NF-κB)激活细胞内的炎性小体并释放促炎细胞因子(例如IL-1β,IL-18、TNF-α和IL-6)。随后,适应性免疫系统的细胞被招募来助长肝脏炎症,肝实质细胞可能经历由gasderminD介导的程序性细胞死亡,称为焦亡。随着肝脏疾病的进展,向2型炎症反应转变,促进组织修复,也促进纤维发生。炎症体激活也可能发生在肝外部位,如代谢功能障碍相关脂肪性肝炎(MASH)的白色脂肪组织。在终末期肝病中,炎症的耀斑(例如,在严重的酒精相关性肝炎中)会激发功能失调的免疫系统,有助于炎症小体介导的肝损伤,并可能导致器官功能障碍/衰竭,如在急性对慢性肝衰竭(ACLF)中所见。这篇综述概述了当前关于肝脏疾病进展中炎性小体激活的概念以及正在为肝病患者开发的相关生物标志物和治疗方法。
    Chronic liver disease (CLD) leads to hepatocellular injury that triggers a pro-inflammatory state in several parenchymal and non-parenchymal hepatic cell types ultimately resulting in liver fibrosis, cirrhosis, portal hypertension (PH) and liver failure. Thus, an improved understanding of the inflammasomes - as key molecular drivers of liver injury - supports the development of novel diagnostic or prognostic biomarkers and effective therapeutics. In liver disease, innate immune cells respond to hepatic noxes by activating cell-intrinsic inflammasomes via toll-like receptors (TLRs) and nuclear factor kappa-B (NF-κB) and release of pro-inflammatory cytokines (such as IL-1β, IL-18, TNF-α and IL-6). Subsequently, cells of the adaptive immune system are recruited to fuel hepatic inflammation, and liver parenchymal cells may undergo programmed cell-death mediated by gasdermin D, termed pyroptosis. With liver disease progression, there is a shift towards a type 2 inflammatory response, which promotes tissue repair but also fibrogenesis. Inflammasome activation may also occur at extrahepatic sites, such as the white adipose tissue in metabolic dysfunction-associated steatohepatitis (MASH). In end-stage liver disease, flares of inflammation (e.g., in severe alcohol-related hepatitis) that spark on a dysfunctional immune system, contribute to inflammasome-mediated liver injury and potentially result in organ dysfunctions/failures, as seen in acute-on-chronic liver failure (ACLF). This review provides an overview on current concepts regarding inflammasome activation in liver disease progression and related biomarkers and therapeutic approaches that are being developed for patients with liver disease.

    背景:在癌症中,胆囊癌是预后最差的癌症之一。由于靠近管腔结构和胆源性腹膜炎的风险,早期病变难以活检。然而,早期手术是完全治愈的唯一机会。利用风险评分可以表征恶性肿瘤的风险并早期转诊到肿瘤中心,从而为胆囊癌患者带来更好的预后。
    方法:本研究的目的是根据临床表现和影像学检查,制定可疑胆囊病变患者的癌症风险评分。对所有在影像学上有可疑胆囊病变并接受手术治疗的患者进行分析。如果超声显示胆囊壁增厚(超过4毫米)并且计算机断层扫描显示可手术疾病,则考虑对患者进行评分。进行统计分析以得出恶性肿瘤的评分。
    结果:2005年1月至2014年12月,共有175例患者因可疑胆囊病变接受了手术。分析的因素包括临床生化和影像学检查结果。其中,最终组织病理学为良性的71例,恶性的104例。分数是由以下变量构成的:女性,高总胆红素(≥1mg/dL),质量的存在,病灶的局灶性位置,在影像学上存在胆囊结石和肝十二指肠区域淋巴结受累。获得模型得分和修正得分。在这个修改后的分数中,20例预测恶性肿瘤中超过8例,敏感性为78%,特异性为70.4%。用这些变量构建的受试者工作特征(ROC)曲线具有0.828的曲线下面积。模子得分与改良得分之间无统计学差别。
    结论:获得了胆囊癌的术前风险评分,这需要在未来进行前瞻性验证。
    BACKGROUND: Among cancers, carcinoma gallbladder has one of the most dismal prognosis. Early lesions are difficult to biopsy because of proximity to luminal structures and risk of biliary peritonitis. However, early surgery offers the only chance of a complete cure. Utilizing a risk score would allow characterization of the risk of malignancy and early referral to an oncology centre thereby resulting in better outcomes for patients with carcinoma gallbladder.
    METHODS: The aim of this study was to develop a risk score for carcinoma in patients with suspicious gallbladder lesions based on clinical presentation and imaging. All patients with suspicious gallbladder lesions on radiological imaging who underwent surgery were analyzed. Patients were considered for scoring if the ultrasound showed the gallbladder wall thickening (more than 4 mm) and computed tomography scan showed operable disease. Statistical analysis was done to derive a score for malignancy.
    RESULTS: Total 175 patients underwent an operation for suspicious gallbladder lesions from January 2005 to December 2014. The factors analyzed were clinical biochemical and imaging findings. Of these, 71 were benign on the final histopathology and 104 were malignant. The score was constructed with the following variables: female sex, high total bilirubin (≥ 1 mg/dL), presence of a mass, focal location of the lesion, presence of gallbladder stones and nodal involvement in the hepatoduodenal region on imaging. A model score and modified score were obtained. In this modified score, score of more than 8 out of 20 predicted malignancy with a sensitivity of 78% and specificity of 70.4%. Receiver operating characteristic (ROC) curve constructed with these variables had an area under curve of 0.828. There was no statistically significant difference between the model score and the modified score.
    CONCLUSIONS: A pre-operative risk score was obtained for carcinoma gallbladder, which needs to be validated prospectively in future.

    背景:血清生物标志物的价值,特别是甲胎蛋白(AFP)和缺乏维生素K或拮抗剂II(PIVKA-II)诱导的蛋白质,在肝细胞癌(HCC)患者的预后评估和复发监测方面越来越受到重视。这项研究调查了这两种生物标志物的血清学不完全转化(SIC)作为HCC切除术后长期预后指标的意义。
    方法:对AFP(>20ng/mL)或PIVKA-II(>40mAU/mL)阳性且接受治愈性切除的HCC患者队列进行了一项多中心观察性研究。根据其术后AFP和PIVKA-II水平在术后第一次随访(术后4~8周),将这些患者分为血清学不完全转换(SIC)和血清学完全转换(SCC)组.研究终点为复发和总生存期(OS)。
    结果:在1755名患者中,379和1376被归类为患有SIC和SCC,分别。SIC组的1年和5年OS率为67.5%和26.3%,相应的复发率为53.2%和79.0%,虽然SCC组的1年和5年OS率分别为95.8%和62.5%,相应的复发率为16.8%和48.8%,分别(两者P<.001)。多因素Cox回归分析表明,术后SIC是复发增加(HR:2.40,95%CI,2.04-2.81,P<.001)和OS降低(HR:2.69,95%CI,2.24-3.24,P<.001)的独立危险因素。
    结论:结果强调AFP或PIVKA-II的术后不完全转换是重要的预后指标,表明肝癌切除术后肿瘤不良结局的风险较高。这一启示对于完善HCC患者的术后辅助治疗和监测策略具有至关重要的意义。
    BACKGROUND: The value of serum biomarkers, particularly alpha-fetoprotein (AFP) and protein induced by vitamin K absence or antagonist-II (PIVKA-II), gains increasing attention in prognostic evaluation and recurrence monitoring for patients with hepatocellular carcinoma (HCC). This study investigated the implications of serological incomplete conversion (SIC) of these 2 biomarkers as prognostic indicators for long-term outcomes after HCC resection.
    METHODS: A multicenter observational study was conducted on a cohort of HCC patients presenting with AFP (>20 ng/mL) or PIVKA-II (>40 mAU/mL) positivity who underwent curative-intent resection. Based on their postoperative AFP and PIVKA-II levels at first postoperative follow-up (4~8 weeks after surgery), these patients were stratified into the serological incomplete conversion (SIC) and serological complete conversion (SCC) groups. The study endpoints were recurrence and overall survival (OS).
    RESULTS: Among 1755 patients, 379 and 1376 were categorized as having SIC and SCC, respectively. The SIC group exhibited 1- and 5-year OS rates of 67.5% and 26.3%, with the corresponding recurrence rates of 53.2% and 79.0%, respectively; while the SCC group displayed 1- and 5-year OS rates of 95.8% and 62.5%, with the corresponding recurrence rates of 16.8% and 48.8%, respectively (both P < .001). Multivariate Cox regression analysis demonstrated that postoperative SIC was an independent risk factor for both increased recurrence (HR: 2.40, 95% CI, 2.04-2.81, P < .001) and decreased OS (HR: 2.69, 95% CI, 2.24-3.24, P < .001).
    CONCLUSIONS: The results emphasize that postoperative incomplete conversion of either AFP or PIVKA-II is a significant prognostic marker, indicating a higher risk for adverse oncologic outcomes following HCC resection. This revelation has crucial implications for refining postoperative adjuvant therapy and surveillance strategies for HCC patients.

    背景:在肝门部胆管癌(pCCA)切缘处进行浸润性癌的额外切除已成为共识。然而,关于残余胆管上皮内瘤变(BilIN)是否需要额外切除仍存在争议.
    方法:纳入来自两家医院的连续pCCA患者。总结切缘BilIN的发生率和规律。分析切缘阴性(R0)和BilIN切缘患者的预后。森林图的Cox回归用于确定与总生存率(OS)和无复发生存率(RFS)相关的独立危险因素。根据BilIN特征和肿瘤特征进行亚组分析。
    结果:306例pCCA患者接受根治性切除。255有R0边缘,51有BilIN边缘。两组间OS(P=0.264)和RFS(P=0.149)差异无统计学意义。具体来说,BilIN在远端胆管19例,在近端胆管32例。42例患者显示低级别BilIN,和9显示高品位。进一步分析显示,不同位置之间的长期生存率没有显着差异(P=0.354),或不同等级之间(P=0.772)。门静脉浸润,分化差和淋巴结转移被认为是OS和RFS的独立危险因素,而Bilin不是。亚组分析显示,淋巴结转移亚组之间的长期生存没有显着差异,或门静脉浸润亚组之间。
    结论:对于接受根治性切除术的pCCA患者,切除边缘残留Bilin是可以接受的。这些患者不需要额外的切除以达到绝对R0边缘。
    BACKGROUND: Additional resection for invasive cancer at perihilar cholangiocarcinoma (pCCA) resection margins has become a consensus. However, controversy still exists regarding whether additional resection is necessary for residual biliary intraepithelial neoplasia (BilIN).
    METHODS: Consecutive patients with pCCA from two hospitals were enrolled. The incidence and pattern of resection margin BilIN were summarized. Prognosis between patients with negative margins (R0) and BilIN margins were analyzed. Cox regression with a forest plot was used to identify independent risk factors associated with overall survival (OS) and recurrence-free survival (RFS). Subgroup analysis was performed based on BilIN features and tumor characteristics.
    RESULTS: 306 pCCA patients receiving curative resection were included. 255 had R0 margins and 51 had BilIN margins. There was no significant difference in OS (P = 0.264) or RFS (P = 0.149) between the two group. Specifically, 19 patients with BilIN at distal bile ducts and 32 at proximal bile ducts. 42 patients showed low-grade BilIN, and 9 showed high-grade. Further analysis revealed no significant difference in long-term survival between different locations (P = 0.354), or between different grades (P = 0.772). Portal vein invasion, poor differentiation and lymph node metastasis were considered independent risk factors for OS and RFS, while BilIN was not. Subgroup analysis showed no significant difference in long-term survival between the lymph node metastasis subgroup, or between the portal vein invasion subgroup.
    CONCLUSIONS: For pCCA patients underwent curative resection, residual BilIN at resection margin is acceptable. Additional resection is not necessary for such patients to achieve absolute R0 margin.

    目的:门脉高压(PH)是慢性肝病最常见的并发症之一。肝硬化患者的外周5-羟色胺(5-HT)水平升高。我们旨在阐明5-HT受体1A(HTR1A)在门静脉(PV)中对PH的功能和机制。
    方法:采用硫代乙酰胺(TAA)注射诱导PH模型,胆管结扎(BDL)或部分门静脉结扎(PPVL)。使用实时PCR检测HTR1A表达,原位杂交和免疫荧光染色。采用原位门静脉内输注来评估5-HT的效果,HTR1A激动剂8-OH-DPAT,和HTR1A拮抗剂WAY-100635对门静脉压力(PP)的影响。利用Htr1a敲除(Htr1a-/-)大鼠和血管平滑肌细胞(VSMC)特异性Htr1a敲除(Htr1aΔVSMC)小鼠来确认HTR1A对PP的调节作用。
    结果:在PH模型大鼠和肝硬化患者的高血压PV中,HTR1A表达明显升高。此外,8-OH-DPAT增加,但WAY-100635降低大鼠的PP,不影响肝纤维化和全身血流动力学。此外,5-HT或8-OH-DPAT直接诱导分离的PV的收缩。大鼠中Htr1a的遗传缺失和小鼠中VSMC特异性Htr1a的敲除可预防PH的发展。此外,5-HT在PV中通过HTR1A触发cAMP途径介导的PVSMCs收缩。我们还证实了阿尔维林作为HTR1A拮抗剂,并证明了其降低TAA-中PP的能力,BDL-,和PPVL诱导的门脉高压大鼠。
    结论:我们的发现表明,5-HT通过诱导PV收缩促进PH,并确定HTR1A是减弱PH的有前途的治疗靶标。作为HTR1A拮抗剂,阿尔维林有望成为临床PH治疗的候选药物。
    OBJECTIVE: Portal hypertension (PH) is one of the most frequent complications of chronic liver disease. The peripheral 5-Hydroxytryptamine (5-HT) level was increased in cirrhotic patients. We aimed to elucidate the function and mechanism of 5-HT receptor 1A (HTR1A) in portal vein (PV) on PH.
    METHODS: PH models were induced by thioacetamide (TAA) injection, bile duct ligation (BDL) or partial portal vein ligation (PPVL). HTR1A expression was detected using real-time PCR, in situ hybridization and immunofluorescence staining. In situ intraportal infusion was employed to assess the effects of 5-HT, the HTR1A agonist 8-OH-DPAT, and the HTR1A antagonist WAY-100635 on portal pressure (PP). Htr1a knock-out (Htr1a-/-) rats and vascular smooth muscle cell (VSMC)-specific Htr1a knock-out (Htr1aΔVSMC) mice were utilized to confirm the regulatory role of HTR1A on PP.
    RESULTS: HTR1A expression was significantly increased in the hypertensive PV of PH model rats and cirrhotic patients. Additionally, 8-OH-DPAT increased but WAY-100635 decreased PP in rats, without affecting liver fibrosis and systemic hemodynamics. Furthermore, 5-HT or 8-OH-DPAT directly induced the contraction of isolated PVs. Genetic deletion of Htr1a in rats and VSMCs-specific Htr1a knock-out in mice prevented the development of PH. Moreover, 5-HT triggered the cAMP pathway-mediated PVSMCs contraction via HTR1A in PV. We also confirmed alverine as an HTR1A antagonist and demonstrated its capacity to decrease PP in TAA-, BDL-, and PPVL-induced portal hypertensive rats.
    CONCLUSIONS: Our findings reveal that 5-HT promotes PH by inducing the contraction of PV, and identify HTR1A as a promising therapeutic target for attenuating PH. As an HTR1A antagonist, alverine is expected to become a candidate for clinical PH treatment.

    目的:肝硬化患者术后并发症的风险增加。目前尚不清楚术前非手术临床医师访视是否能改善术后预后。我们评估了术前初级保健医师(PCP)和/或胃肠病学家/肝病学家(GI/Hep)访视对肝硬化患者手术后死亡率的影响,并探讨了药物变化和穿刺率作为潜在介质的差异。
    方法:这是退伍军人健康管理局在2008年至2016年间接受手术的肝硬化患者的回顾性队列研究。我们比较了1982例术前PCP和/或GI/Hep就诊的患者与1846例没有术前就诊的倾向匹配的患者。我们使用Cox回归和Fine和Gray竞争风险回归来评估术前就诊类型与术后6个月死亡率之间的关系。
    结果:术前GI/Hep和PCP访视的患者与未术前访视的患者相比,术后死亡率降低了45%(风险比[HR],0.55;95%置信区间[CI],0.35-0.87)。单独使用GI/Hep术前访视观察到较小的效应大小(HR,0.69;95%CI,0.48-0.99)或单纯PCP访视(HR,0.70;95%CI,0.53-0.93)。术前PCP/GI/Hep就诊的患者更有可能使用利尿剂,自发性细菌性腹膜炎的预防,和肝性脑病药物新开始和/或剂量调整,与没有术前访视的患者相比,更有可能接受术前穿刺。
    结论:术前PCP/GI/Hep访视与术后死亡风险降低相关,其中PCP和GI/Hep访视的风险降低最大。这种协同效应突出了多学科方法在肝硬化患者术前护理中的重要性。
    OBJECTIVE: Cirrhosis patients are at increased risk for postoperative complications. It remains unclear whether preoperative nonsurgical clinician visits improve postoperative outcomes. We assessed the impact of preoperative primary care physician (PCP) and/or Gastroenterologist/Hepatologist (GI/Hep) visits on postoperative mortality in cirrhosis patients undergoing surgery and explored differences in medication changes and paracentesis rates as potential mediators.
    METHODS: This was a retrospective cohort study of cirrhosis patients in the Veterans Health Administration who underwent surgery between 2008 and 2016. We compared 1982 patients with preoperative PCP and/or GI/Hep visits with 1846 propensity matched patients without preoperative visits. We used Cox regression and Fine and Gray competing risk regression to evaluate the association between preoperative visit type and postoperative mortality at 6 months.
    RESULTS: Patients with preoperative GI/Hep and PCP visits had a 45% lower hazard of postoperative mortality compared to those without preoperative visits (hazard ratio [HR], 0.55; 95% confidence interval [CI], 0.35-0.87). A smaller effect size was noted with GI/Hep preoperative visit alone (HR, 0.69; 95% CI, 0.48-0.99) or PCP visit alone (HR, 0.70; 95% CI, 0.53-0.93). Patients with preoperative PCP/GI/Hep visits were more likely to have diuretics, spontaneous bacterial peritonitis prophylaxis, and hepatic encephalopathy medications newly initiated and/or dose adjusted and more likely to receive preoperative paracentesis as compared to those without preoperative visits.
    CONCLUSIONS: Preoperative PCP/GI/Hep visits are associated with a reduced risk of postoperative mortality with the greatest risk reduction observed in those with both PCP and GI/Hep visits. This synergistic effect highlights the importance of a multidisciplinary approach in the preoperative care of cirrhosis patients.

    目的:慢性乙型肝炎(CHB)叠加肝性脂肪变性(HS)的全球上升,评估纤维化进展的精确工具。这项研究利用机器学习(ML)来开发该患者人群中晚期纤维化和肝硬化的诊断模型。
    方法:在十个医疗中心接受肝活检的并发HS的幼稚CHB患者作为训练队列和独立的外部验证队列(NCT05766449)。实施六个ML模型来预测晚期纤维化和肝硬化。最终的模型,源自Shapley添加剂扩张,与纤维化-4指数(FIB-4)进行比较,非酒精性脂肪性肝病纤维化评分(NFS),和天冬氨酸转氨酶与血小板比率指数(APRI)使用接受者工作特征曲线下面积(AUROC),和决策曲线分析(DCA)。
    结果:在1,198名合格患者中,随机森林(RF)模型在训练队列中诊断晚期纤维化(RF-AF模型)和诊断肝硬化(RF-C模型)的AUROC为0.778[95%置信区间(CI)0.749-0.807],并在验证队列中保持较高的AUROC。在训练组中,RF-AF模型在HBVDNA≥105IU/ml的患者中获得了0.825(95%CI0.787-0.862)的AUROC,在女性患者中,RF-C模型的AUROC为0.828(95%CI0.774-0.883)。这两种型号的性能优于FIB-4、NFS、和APRI在训练组中,并且在验证队列中也表现良好。
    结论:RF模型提供了可靠的,非侵入性工具,用于识别慢性乙型肝炎患者并发HS的晚期纤维化和肝硬化,在这两种疾病的共同管理方面取得了重大进展。
    OBJECTIVE: The global rise of chronic hepatitis B (CHB) superimposed on hepatic steatosis (HS) warrants non-invasive, precise tools for assessing fibrosis progression. This study leveraged machine learning (ML) to develop diagnostic models for advanced fibrosis and cirrhosis in this patient population.
    METHODS: Treatment-naive CHB patients with concurrent HS who underwent liver biopsy in ten medical centers were enrolled as a training cohort and an independent external validation cohort (NCT05766449). Six ML models were implemented to predict advanced fibrosis and cirrhosis. The final models, derived from Shapley Additive exPlanations, were compared to Fibrosis-4 Index (FIB-4), Nonalcoholic fatty liver disease Fibrosis Score (NFS), and Aspartate transaminase to platelet ratio index (APRI) using the area under receiver operating characteristic curve (AUROC), and decision curve analysis (DCA).
    RESULTS: Of 1,198 eligible patients, the random forest (RF) model achieved AUROCs of 0.778 [95% confidence interval (CI) 0.749-0.807] for diagnosing advanced fibrosis (RF-AF model) and 0.777 (95%CI 0.748-0.806) for diagnosing cirrhosis (RF-C model) in the training cohort, and maintained high AUROCs in the validation cohort. In the training cohort, the RF-AF model obtained an AUROC of 0.825 (95% CI 0.787-0.862) in patients with HBV DNA ≥105 IU/ml, and RF-C model had an AUROC of 0.828 (95% CI 0.774-0.883) in female patients. The two models outperformed FIB-4, NFS, and APRI in the training cohort, and also performed well in the validation cohort.
    CONCLUSIONS: The RF models provide reliable, non-invasive tools for identifying advanced fibrosis and cirrhosis in CHB patients with concurrent HS, offering a significant advancement in the co-management of the two diseases.
