Background & Aims

Direct-acting antiviral agents (DAA)-mediated HCV cure correlates with better outcomes, but there are insufficient data on detailed mortality-related risk factors after cure. This study sought to clarify mortality and associated risk factors post-HCV cure.

Methods

The study included HCV patients with sustained virological response following DAA (DAA-SVR) from 39 REAL-C centres in North America, Europe and Asia-Pacific. The primary outcome was all-cause mortality in DAA-SVR patients. Mortality rate per 1000 patient-years (PY) was calculated as the number of deaths divided by total PY multiplied by 1000.

Results

A total of 10 034 DAA-SVR patients (stratified by cirrhosis status: 5611 non-cirrhosis, 4153 compensated, 270 decompensated) were included. With a median follow-up of 4.76 PY, 4.9% (491) died. The all-cause mortality rates were 6.2, 13.1, 60.0 and 10.4 per 1000 PY for patients without cirrhosis, compensated and decompensated cirrhosis, and overall patients, respectively. The 5-year cumulative survival was 95.1% (94.5%–95.6%) overall, with the lowest rate of 73.9% (67.0%–79.5%) in decompensated cirrhosis. Non-liver-related death was the main cause in non-cirrhosis (non-liver-related vs. liver: 5.2 vs. 0.8 per 1000 PY)/compensated cirrhosis (8.2 vs. 4.8 per 1000 PY), while liver-related death was dominant in decompensated cirrhosis (24.7 vs. 33.8 per 1000 PY). Risk factors for higher mortality included age > 65 (3.2-fold), male (1.5-fold), cirrhosis (decompensated 7.6-fold) and baseline DM (1.5-fold).

Conclusion

This study showed significant age, sex, fibrosis stage and DM differences in mortality and causes among DAA-SVR patients. It provided granular subgroup data for precision medicine to support individualised care, future modelling studies and public health planning.

背景与目的:直接作用抗病毒药物(DAA)介导的HCV治愈与更好的预后相关,但关于治愈后死亡相关危险因素的详细数据不足。本研究旨在澄清hcv治愈后的死亡率和相关危险因素。方法:该研究纳入了来自北美、欧洲和亚太地区39个REAL-C中心的DAA (DAA- svr)后持续病毒学反应的HCV患者。主要终点是DAA-SVR患者的全因死亡率。每1000病人年死亡率(PY)的计算方法为死亡人数除以总PY乘以1000。结果:共纳入10034例DAA-SVR患者(按肝硬化状态分层:非肝硬化5611例,代偿4153例,代偿270例)。中位随访时间为4.76个月,4.9%(491)死亡。无肝硬化患者、代偿性和失代偿性肝硬化患者和整体患者的全因死亡率分别为6.2、13.1、60.0和10.4 / 1000 PY。总体5年累积生存率为95.1%(94.5%-95.6%),失代偿期肝硬化最低生存率为73.9%(67.0%-79.5%)。非肝脏相关死亡是非肝硬化(非肝脏相关vs.肝脏:5.2 vs. 0.8 / 1000 PY)/代偿性肝硬化(8.2 vs. 4.8 / 1000 PY)的主要原因,而肝脏相关死亡在失代偿性肝硬化中占主导地位(24.7 vs. 33.8 / 1000 PY)。较高死亡率的危险因素包括年龄(3.2倍)、男性(1.5倍)、肝硬化(代偿失代偿7.6倍)和基线糖尿病(1.5倍)。结论:本研究显示DAA-SVR患者的死亡率和病因在年龄、性别、纤维化分期和DM方面存在显著差异。它为精准医疗提供了细粒度的亚组数据,以支持个性化护理、未来的建模研究和公共卫生规划。

不可切除的肝细胞癌(HCC)的治疗前景已经被基于免疫检查点抑制剂的联合治疗方案所改变。在IMbrave150试验之后,atezolizumab + bevacizumab (Atez/Bev)已成为肝功能保留患者首选的一线全身治疗方案。然而,这一范式几乎完全建立在Child-Pugh A级肝硬化患者的证据之上,这使得现实世界中相当大比例的患者,即Child-Pugh B级(CP-B)患者,处于持续的证据缺口中。在日常实践中,临床医生经常面临这样的困境:是为CP-B肝功能患者提供积极的全身治疗,还是默认最佳支持治疗。传统上,CP-B被视为免疫治疗的相对禁忌症,主要是由于对安全性(如出血风险)和有限的生存获益的担忧[2,3]。然而,CP-B代表了一个异质人群,将其作为一个统一的类别可能会过度简化一个更加微妙的临床现实。在这种背景下,Sasaki及其同事b[4]的多中心回顾性研究提供了及时和临床相关的见解。通过分析日本10家机构近800名接受Atez/Bev治疗的患者,包括相当大的CP-B患者队列,作者解决了随机试验在很大程度上避免的问题:“哪些CP-B肝功能患者仍然可以从一线免疫治疗的联合治疗中受益?”与之前的真实世界报告一致,该研究证实,与CP-A患者相比,CP-B患者的无进展生存期和总生存期更短[5,6]。值得注意的是,Atez/Bev的安全性在两组之间大致相当,停药率和免疫相关不良事件发生率相似。虽然出血相关事件在CP-B患者中更为频繁,但当分析仅限于一线治疗时,这种超额风险被减弱,这加强了患者选择和治疗时机的重要性。本研究最引人注目的贡献不在于重申CP-B结果较差,而在于证明CP-B结果并不统一。值得注意的是,Child-Pugh评分本身未能对CP-B的预后进行有意义的分层。相比之下,改良的白蛋白-胆红素(mALBI)分级明确区分了结果截然不同的患者。具体而言,CP-B和mALBI≤2b级患者的无进展生存期和总生存期与先前报道的全身治疗结果相比有利,而mALBI 3级患者的结果则令人沮丧,这与最佳支持治疗相似。这些发现表明,肝脏功能储备,而不是单独的Child-Pugh分级,应该指导治疗决策。在这种情况下,mALBI分级似乎提供了更细粒度和临床可操作的肝功能评估。与将CP-B视为二元排除标准不同,本研究支持一种更精细的方法,即选择CP-B患者,例如mALBI分级≤2b的患者,可能是Atez/Bev的合理候选者。相反,mALBI 3级患者似乎不太可能获得有意义的益处,支持治疗或参加临床试验可能会更好。研究结果还提出了关于方案选择的重要考虑。含贝伐单抗的治疗存在固有的出血风险,尤其是门静脉高压症患者[1,2]。尽管目前的研究表明,在精心挑选的CP-B患者中,安全性是可以接受的,但它也强调了警惕风险评估的必要性,特别是在后期的治疗中。是否无vegf的免疫治疗方案可能为边缘肝储备患者提供一个更安全的选择仍然是一个悬而未决的问题。Sasaki等人目前的研究强调了一个简单但重要的信息:CP-B不是一块巨石。通过将重点从分类分类转移到功能分层,本研究为将基于免疫治疗的治疗扩展到精心挑选的患者提供了一个实用的框架,否则这些患者可能会被拒绝积极治疗。这样一来,它使该领域向晚期HCC的真正个体化治疗迈进了一步。考虑到在CP-B肝功能患者中进行前瞻性试验的固有挑战,高质量的真实数据可以为服务不足的患者群体提供重要指导。作者声明无利益冲突。数据共享不适用于本文,因为在当前研究期间没有生成或分析数据集。

Background

Systemic therapy combined with transcatheter arterial chemoembolization (TACE) is the main treatment strategy for patients with unresectable hepatocellular carcinoma (uHCC). Nevertheless, there are currently few direct comparative studies between different combined treatment regimens. Therefore, this study aims to compare the efficacy and safety of sintilimab and bevacizumab biosimilar (IBI305) versus PD-1 inhibitor and tyrosine kinase inhibitor (TKI) combined with TACE in the treatment of uHCC.

Methods

This retrospective study included 225 patients with uHCC who received either TACE combined with sintilimab and IBI305 (TSB group, n = 84) or other PD-1 inhibitors and TKIs (TTP group, n = 141). This study evaluated overall survival (OS) as the primary outcome, with secondary endpoints encompassing progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR)and treatment-related adverse events (TRAEs). To mitigate potential confounding biases across the two cohorts, propensity score matching (PSM) was employed.

Results

Following PSM, 136 uHCC patients were included, with 68 in both the TSB and TTP groups. There was no statistical difference in OS (p = 0.18) or PFS (p = 0.34) between the TSB group and the TTP group. According to both RECIST1.1 and mRECIST criteria, there were no notable changes in ORR or DCR. Both groups demonstrated manageable toxicity profiles. Subgroup analysis suggested that whereas patients with large tumours (HR, 0.33; p = 0.024), solitary lesions (HR, 0.16; p < 0.001) or portal vein tumour thrombosis (HR, 0.43; p = 0.033) derived greater survival benefit from the TSB regimen, those with multifocal tumours (HR, 1.86; p = 0.033) benefited more from the TTP regimen.

Conclusions

The TSB and TTP regimens offer comparable efficacy and safety in uHCC, yet the TSB regimen appears to offer greater benefit in specific patient subgroups.

背景:全身治疗联合经导管动脉化疗栓塞(TACE)是不可切除肝细胞癌(uHCC)患者的主要治疗策略。然而,目前很少有不同联合治疗方案之间的直接比较研究。因此,本研究旨在比较辛替单抗和贝伐单抗生物类似药(IBI305)与PD-1抑制剂和酪氨酸激酶抑制剂(TKI)联合TACE治疗uHCC的疗效和安全性。方法:本回顾性研究纳入了225例接受TACE联合西替单抗和IBI305 (TSB组,n = 84)或其他PD-1抑制剂和TKIs (TTP组,n = 141)治疗的uHCC患者。该研究评估了总生存期(OS)作为主要终点,次要终点包括无进展生存期(PFS)、客观缓解率(ORR)、疾病控制率(DCR)和治疗相关不良事件(TRAEs)。为了减轻两个队列之间潜在的混淆偏差,采用倾向评分匹配(PSM)。结果:PSM后纳入136例uHCC患者,其中TSB组和TTP组均有68例。TSB组与TTP组的OS (p = 0.18)、PFS (p = 0.34)差异均无统计学意义。根据RECIST1.1和mRECIST标准,ORR和DCR均无显著变化。两组均表现出可控的毒性。亚组分析表明,大肿瘤患者(HR, 0.33; p = 0.024),孤立病变患者(HR, 0.16; p)。结论:TSB和TTP方案在uHCC中具有相当的疗效和安全性,但TSB方案似乎在特定患者亚组中具有更大的益处。

Background & Aims

Metabolic dysfunction-associated steatotic liver disease (MASLD) and pancreatic steatosis (PS) are interconnected ectopic fat conditions linked to cardiometabolic dysregulation. Their combined effect on the long-term risk of cardiometabolic multimorbidity (CMM; ≥ 2 of diabetes, hypertension, coronary heart disease, and stroke) and cardiac remodelling remains unclear.

Methods

We examined cross-sectional associations between PS and the severity of MASLD histology in a biopsy-proven MASLD cohort from China. Subsequently, using the UK Biobank, we assessed the long-term risk of developing both incident CMM and cardiac structural/functional alterations (via cardiac magnetic resonance [CMR]) associated with single-organ versus dual-organ steatosis. Exploratory proteomic profiling was performed to identify potential molecular pathways.

Results

In the biopsy-proven cohort (n = 482), both continuous pancreatic proton density fat fraction and PS status were associated with severe hepatic steatosis, lobular inflammation, and fibrosis (all p < 0.05). In the UK Biobank cohort (n = 16 408; median follow-up of 5.6 years), the coexistence of MASLD and PS additively increased the risk of new-onset CMM (HR = 2.013, 95% CI: 1.219–3.322, p = 0.006). Dual-organ steatosis was also associated with marked cardiac alterations, specifically increased left ventricular mass and impaired ventricular function. Proteomics revealed upregulation of lysosomal catabolic and glycosaminoglycan-degrading pathways in dual-organ steatosis compared to single-organ steatosis. Gene Ontology highlighted heparan sulphate proteoglycan catabolism as a hallmark of dual-organ involvement.

Conclusion

PS is associated with greater severity of MASLD histology, and the concomitant involvement of both the liver and pancreas drives a higher risk of CMM and cardiac remodelling.

背景与目的:代谢功能障碍相关的脂肪性肝病(MASLD)和胰腺脂肪变性(PS)是相互关联的异位脂肪状况,与心脏代谢失调有关。它们对心脏代谢多病(CMM;≥2的糖尿病、高血压、冠心病和中风)和心脏重构的长期风险的综合影响尚不清楚。方法:我们在来自中国的活检证实的MASLD队列中研究了PS与MASLD组织学严重程度之间的横断面关联。随后,我们使用UK Biobank,评估了发生CMM和心脏结构/功能改变(通过心脏磁共振[CMR])与单器官和双器官脂肪变性相关的长期风险。进行探索性蛋白质组学分析以确定潜在的分子途径。结果:在活检证实的队列中(n = 482),连续胰腺质子密度脂肪分数和PS状态都与严重的肝脏脂肪变性、小叶炎症和纤维化相关(均为p)。结论:PS与更严重的MASLD组织学相关,同时累及肝脏和胰腺会增加CMM和心脏重构的风险。

Background

Chronic liver diseases (CLD) leading to liver fibrosis and cirrhosis are a major cause of morbidity and mortality in sub-Saharan Africa and pose a significant burden on its health care systems. We aimed to elucidate the prevalence of fibrosis/cirrhosis in patients seeking health care in Kumasi, Ghana, and its underlying aetiologies.

Methods

In this cross-sectional study, we performed sonography, transient elastography as well as biochemical and virological analyses.

Results

Transient elastography indicated fibrosis/cirrhosis in 24.5% (113/461) of participants. Liver cirrhosis was significantly associated with known hepatitis B virus (HBV) infection, lack of formal education, hospitalisation, and male sex. Prevalence of active hepatitis B was significantly higher in patients with liver cirrhosis compared to controls (54.6% [30/55] vs. 17.1% [19/111]), as was anti-HBc (94.6% [52/55] vs. 80.2% [89/111]). CLD was mainly attributed to HBV (27.3%, 30/110), alcohol abuse (11.8%, 13/110), a combination of both (10.9%, 12/110), and metabolic dysfunction-associated steatotic liver disease (MASLD) (20%, 22/110). Antiviral treatment was indicated in 24 patients with active hepatitis B (number-needed-to-screen: 19.2). Hepatitis C and D viruses were of minor importance (2.7% [3/110] and 0.9% [1/110], respectively).

Conclusions

We found a high prevalence of CLD, predominantly caused by HBV, MASLD and alcohol. We confirmed the use of transient elastography as a non-invasive and easily applicable tool in resource-limited settings. Our findings underscore the need for systematic screening of hospitalised patients, especially men, in sub-Saharan Africa. Comprehensive screening, treatment, vaccination and prevention programs for HBV, as the leading cause of chronic liver disease, are warranted.

背景:导致肝纤维化和肝硬化的慢性肝病(CLD)是撒哈拉以南非洲发病率和死亡率的主要原因,并对其卫生保健系统构成重大负担。我们的目的是阐明在加纳库马西求医的患者中纤维化/肝硬化的患病率及其潜在的病因。方法:在横断面研究中,我们进行了超声、瞬态弹性成像以及生化和病毒学分析。结果:瞬时弹性成像显示24.5%(113/461)的参与者有纤维化/肝硬化。肝硬化与已知乙型肝炎病毒(HBV)感染、缺乏正规教育、住院和男性显著相关。肝硬化患者的活动性乙型肝炎患病率明显高于对照组(54.6%[30/55]对17.1%[19/111]),抗hbc患者的患病率也明显高于对照组(94.6%[52/55]对80.2%[89/111])。CLD主要归因于HBV(27.3%, 30/110)、酒精滥用(11.8%,13/110)、两者联合(10.9%,12/110)和代谢功能障碍相关的脂肪变性肝病(MASLD)(20%, 22/110)。24例活动性乙型肝炎患者接受了抗病毒治疗(需要筛查的人数:19.2)。丙型肝炎病毒和丁型肝炎病毒影响较小(分别为2.7%[3/110]和0.9%[1/110])。结论:我们发现CLD的患病率很高,主要由HBV、MASLD和酒精引起。我们确认瞬态弹性成像是一种非侵入性的、在资源有限的情况下易于应用的工具。我们的研究结果强调了对撒哈拉以南非洲地区住院患者,特别是男性进行系统筛查的必要性。HBV作为慢性肝病的主要病因,全面的筛查、治疗、疫苗接种和预防计划是必要的。

Background

Hepatitis B virus (HBV) genomes integrated into human DNA significantly contribute to surface antigen (HBsAg) production and may drive hepatocellular carcinoma (HCC). Long-read sequencing methods like Nanopore offer advantages over short-read next-generation sequencing (NGS) by providing continuous reads of whole transcripts, but their application to HBV integration analysis remains limited.

Objective

To develop and apply a method combining semi-nested PCR with Nanopore sequencing to analyse HBV transcripts, including canonical RNA, HBV–human fusion transcripts, and spliced forms in patients with HBV- or hepatitis D virus (HDV)-induced liver disease.

Methods

Nine liver-transplanted patients with HBV- or HDV-related cirrhosis or HCC were studied. Semi-nested PCR was used to amplify all HBV transcripts, followed by Nanopore sequencing. The approach allowed differentiation between canonical (cccDNA-derived) and fusion transcripts. Reads containing the 3′ redundancy beyond nucleotide 1826, exclusive to cccDNA-derived RNA, were quantified to determine the source of HBV RNA.

Results

Unique and total HBV-human fusion RNA reads correlated with serum levels of HBV DNA and HBsAg. Integration-derived RNA accounted for a median of 97% (range: 16%–100%) of HBV RNA. PreS1 RNA levels were much lower than preS2 but sufficient for HDV particle production in an HDV patient without cccDNA-derived transcripts.

Conclusion

This method enables a simplified and comprehensive analysis of HBV transcripts. The results highlight the predominance of integration-derived RNA and support the presence of cccDNA-independent hepatitis D virus production. Nanopore sequencing offers valuable insights into HBV and HDV biology, supporting its role in understanding viral pathogenesis and therapeutic targeting.

背景:乙型肝炎病毒(HBV)基因组整合到人类DNA中,显著促进表面抗原(HBsAg)的产生,并可能驱动肝细胞癌(HCC)。像Nanopore这样的长读测序方法通过提供全转录本的连续读取,比短读下一代测序(NGS)具有优势,但它们在HBV整合分析中的应用仍然有限。目的:建立并应用半巢式PCR与纳米孔测序相结合的方法来分析HBV转录物,包括HBV-或丁型肝炎病毒(HDV)诱导的肝病患者的典型RNA、HBV-人融合转录物和剪接形式。方法:对9例肝移植合并HBV或HBV相关肝硬化或HCC患者进行研究。采用半巢式PCR扩增所有HBV转录本,然后进行纳米孔测序。这种方法可以区分标准转录本(cccdna衍生)和融合转录本。对cccdna衍生的RNA中含有超过核苷酸1826的3'冗余的Reads进行定量,以确定HBV RNA的来源。结果:HBV-人融合RNA的独特和总读数与血清HBV DNA和HBsAg水平相关。整合源性RNA中位数占HBV RNA的97%(范围:16%-100%)。PreS1 RNA水平远低于preS2,但在没有cccdna衍生转录物的HDV患者中,PreS1 RNA水平足以产生HDV颗粒。结论:该方法可以简化和全面地分析HBV转录本。结果强调整合衍生RNA的优势,并支持存在不依赖cccdna的丁型肝炎病毒生产。纳米孔测序为HBV和HDV生物学提供了有价值的见解,支持其在理解病毒发病机制和治疗靶向方面的作用。

Reads containing the 3′ redundancy beyond nucleotide 1826, exclusive to cccDNA-derived RNA, were quantified to determine the source of HBV RNA.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Unique and total HBV-human fusion RNA reads correlated with serum levels of HBV DNA and HBsAg. Integration-derived RNA accounted for a median of 97% (range: 16%–100%) of HBV RNA. PreS1 RNA levels were much lower than preS2 but sufficient for HDV particle production in an HDV patient without cccDNA-derived transcripts.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>This method enables a simplified and comprehensive analysis of HBV transcripts. The results highlight the predominance of integration-derived RNA and support the presence of cccDNA-independent hepatitis D virus production. Nanopore sequencing offers valuable insights into HBV and HDV biology, supporting its role in understanding viral pathogenesis and therapeutic targeting.</p>\u0000 </section>\u0000 </div>","PeriodicalId":18101,"journal":{"name":"Liver International","volume":"46 3","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12902805/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146181101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
