    背景:建议使用非选择性β受体阻滞剂治疗具有临床意义的门静脉高压症(CSPH)的患者(即,卡维地洛)通过更新BavenoVII共识来预防第一次肝失代偿事件。CSPH定义为肝静脉压力梯度(HVPG)≥10mmHg;然而,HVPG测量由于其侵入性而未被广泛采用。肝硬度(LS)≥25kPa可用作HVPG≥10mmHg的替代品,以统治CSPH,在大多数患者病因中有90%的阳性预测值。一个令人信服的论据是存在使用LS≥25kPa来诊断CSPH,然后开始卡维地洛患者代偿期肝硬化,在此诊断标准下,约5%-6%的患者可能无法从卡维地洛获益,并且有降低心率和平均动脉压的风险.关于使用卡维地洛预防LS诊断的CSPH中肝脏失代偿的随机对照试验仍有待阐明。因此,我们旨在调查LS≥25kPa的代偿性肝硬化患者是否可以从卡维地洛治疗中获益.
    方法:这项研究是一项随机的,双盲,安慰剂对照,多中心试验。我们将随机分配446名成人代偿性肝硬化患者,LS≥25kPa,没有任何先前的失代偿期事件,也没有高风险的胃食管静脉曲张。患者随机分为两组,A组223名受试者,B组223名受试者,A组为卡维地洛干预组,B组为安慰剂组。两组中的所有患者都将接受病因治疗,并以6个月的间隔进行随访。肝硬化相关和肝脏相关死亡失代偿性事件的3年发生率是主要结果。次要结果包括门静脉高压症的每种并发症的发展(腹水,静脉曲张出血或明显的肝性脑病),自发性细菌性腹膜炎和其他细菌感染的发展,新静脉曲张的发展,小静脉曲张生长为大静脉曲张,LS和脾僵硬的δ变化,通过Child-Pugh和终末期肝病评分模型评估肝功能障碍的变化,血小板计数的变化,肝细胞癌的发展,3年随访门静脉血栓形成和不良事件的发展。将执行预定义的中期分析以确保计算是合理的。
    背景:研究方案已获得沈阳市第六人民医院伦理委员会(2023-05-003-01)和中大医院临床研究独立伦理委员会的批准,隶属于东南大学(2023ZDSYLL433-P01)。该试验的结果将提交在同行评审的期刊上发表,并将在国际会议上发表。
    背景:ChiCTR2300073864。
    BACKGROUND: Patients with clinically significant portal hypertension (CSPH) are recommended to be treated with non-selective beta-blockers (ie, carvedilol) to prevent the first hepatic decompensation event by the renewing Baveno VII consensus. CSPH is defined by hepatic venous pressure gradient (HVPG)≥10 mm Hg; however, the HVPG measurement is not widely adopted due to its invasiveness. Liver stiffness (LS)≥25 kPa can be used as a surrogate of HVPG≥10 mm Hg to rule in CSPH with 90% of the positive predicting value in majority aetiologies of patients. A compelling argument is existing for using LS≥25 kPa to diagnose CSPH and then to initiate carvedilol in patients with compensated cirrhosis, and about 5%-6% of patients under this diagnosis criteria may not be benefited from carvedilol and are at risk of lower heart rate and mean arterial pressure. Randomised controlled trial on the use of carvedilol to prevent liver decompensation in CSPH diagnosed by LS remains to elucidate. Therefore, we aimed to investigate if compensated cirrhosis patients with LS≥25 kPa may benefit from carvedilol therapy.
    METHODS: This study is a randomised, double-blind, placebo-controlled, multicentre trial. We will randomly assign 446 adult compensated cirrhosis patients with LS≥25 kPa and without any previous decompensated event and without high-risk gastro-oesophageal varices. Patients are randomly divided into two groups, with 223 subjects in group A and 223 subjects in group B. Group A is a carvedilol intervention group, while group B is a placebo group. All patients in both groups will receive aetiology therapies and are followed up at an interval of 6 months. The 3-year incidences of decompensated events of cirrhosis-related and liver-related death are the primary outcome. The secondary outcomes include development of each complication of portal hypertension individually (ascites, variceal bleeding or overt hepatic encephalopathy), development of spontaneous bacterial peritonitis and other bacterial infections, development of new varices, growth of small varices to large varices, delta changes in LS and spleen stiffness, change in hepatic dysfunction assessed by Child-Pugh and model for end-stage liver disease score, change in platelet count, development of hepatocellular carcinoma, development of portal vein thrombosis and adverse events with a 3-year follow-up. A predefined interim analysis will be performed to ensure that the calculation is reasonable.
    BACKGROUND: The study protocol has been approved by the ethics committees of the Sixth People\'s Hospital of Shenyang (2023-05-003-01) and independent ethics committee for clinical research of Zhongda Hospital, affiliated to Southeast University (2023ZDSYLL433-P01). The results from this trial will be submitted for publication in peer-reviewed journals and will be presented at international conferences.

    背景:尽管2016年普遍获得政府资助的直接作用抗病毒药物(DAA),但澳大利亚的丙型肝炎治疗吸收率已大幅下降。大多数丙型肝炎与注射毒品有关;减少注射毒品(PWID)人群中的丙型肝炎负担是,因此,最重要的是达到消除丙型肝炎的目标。通过PWID增加DAA摄取对于阻断传播和减少发病率是重要的,以及降低发病率和死亡率,提高PWID的生活质量,并达到澳大利亚消除丙型肝炎的目标。
    方法:将进行一组随机交叉试验,包括三个干预组和一个对照组。A组将接受快速丙型肝炎病毒(HCV)抗体检测;B组将接受快速HCV抗体和快速RNA检测;C组将接受快速HCV抗体检测和HCV抗体阳性参与者的当天治疗开始;控制臂将接受标准护理。主要结果将是(a)HCV开始治疗的参与者的比例和(b)HCV达到治愈的参与者的比例。分析将在意向治疗的基础上使用混合效应逻辑回归模型进行。
    背景:该研究已获得Alfred伦理委员会的批准(编号HREC/64731/Alfred-2020-217547)。每位参与者将提供书面知情同意书。可报告的不良事件将报告给审查伦理委员会。研究结果将在科学会议上发表,并在同行评审的期刊上发表。
    背景:NCT05016609。
    该研究于2022年3月9日开始招聘,预计将于2024年12月完成招聘。
    BACKGROUND: Despite universal access to government-funded direct-acting antivirals (DAAs) in 2016, the rate of hepatitis C treatment uptake in Australia has declined substantially. Most hepatitis C is related to injecting drug use; reducing the hepatitis C burden among people who inject drugs (PWID) is, therefore, paramount to reach hepatitis C elimination targets. Increasing DAA uptake by PWID is important for interrupting transmission and reducing incidence, as well as reducing morbidity and mortality and improving quality of life of PWID and meeting Australia\'s hepatitis C elimination targets.
    METHODS: A cluster randomised cross-over trial will be conducted with three intervention arms and a control arm. Arm A will receive rapid hepatitis C virus (HCV) antibody testing; arm B will receive rapid HCV antibody and rapid RNA testing; arm C will receive rapid HCV antibody testing and same-day treatment initiation for HCV antibody-positive participants; the control arm will receive standard of care. The primary outcomes will be (a) the proportion of participants with HCV commencing treatment and (b) the proportion of participants with HCV achieving cure. Analyses will be conducted on an intention-to-treat basis with mixed-effects logistic regression models.
    BACKGROUND: The study has been approved by the Alfred Ethics Committee (number HREC/64731/Alfred-2020-217547). Each participant will provide written informed consent. Reportable adverse events will be reported to the reviewing ethics committee. The findings will be presented at scientific conferences and published in peer-reviewed journals.
    BACKGROUND: NCT05016609.
    UNASSIGNED: The study commenced recruitment on 9 March 2022 and is expected to complete recruitment in December 2024.

    丙型肝炎病毒(HCV)仍然是一个重大的全球健康挑战。根据世界卫生组织,截至2024年,约有5000万人患有慢性丙型肝炎,这对全球发病率和死亡率造成了广泛的影响。几种直接作用抗病毒(DAA)方案的出现和批准显着改善了HCV治疗,提供潜在的高治愈率的慢性丙型肝炎,然而,最终根除HCV的有希望的目标仍然具有挑战性.主要挑战包括不同地区DAA访问的可变性,不同患者人群和HCV基因型/亚型对DAA的反应率略有不同,以及抗性相关替换(RAS)的出现,可能赋予DAAs抗性。因此,需要定期重新评估当前的HCV知识.根据观察到的HCV流行病学趋势的变化,还需要对HCV进行最新的审查。不断发展和批准治疗策略,以及公共卫生政策的变化。因此,目前的全面审查旨在整合流行病学的最新知识,病理生理学,诊断方法,HCV的治疗选择和预防策略,特别关注当前与RAS相关的挑战和疫苗开发的持续努力。这篇评论试图为医疗保健专业人员提供,研究人员,和政策制定者有必要的见解,以更有效地解决HCV负担。我们旨在强调在管理和预防HCV感染方面取得的进展,并强调挑战HCV感染预防的持续障碍。总体目标是与全球卫生目标保持一致,以减轻慢性肝炎的负担,目标是到2030年最终消除其作为公共卫生威胁。
    Hepatitis C virus (HCV) remains a significant global health challenge. Approximately 50 million people were living with chronic hepatitis C based on the World Health Organization as of 2024, contributing extensively to global morbidity and mortality. The advent and approval of several direct-acting antiviral (DAA) regimens significantly improved HCV treatment, offering potentially high rates of cure for chronic hepatitis C. However, the promising aim of eventual HCV eradication remains challenging. Key challenges include the variability in DAA access across different regions, slightly variable response rates to DAAs across diverse patient populations and HCV genotypes/subtypes, and the emergence of resistance-associated substitutions (RASs), potentially conferring resistance to DAAs. Therefore, periodic reassessment of current HCV knowledge is needed. An up-to-date review on HCV is also necessitated based on the observed shifts in HCV epidemiological trends, continuous development and approval of therapeutic strategies, and changes in public health policies. Thus, the current comprehensive review aimed to integrate the latest knowledge on the epidemiology, pathophysiology, diagnostic approaches, treatment options and preventive strategies for HCV, with a particular focus on the current challenges associated with RASs and ongoing efforts in vaccine development. This review sought to provide healthcare professionals, researchers, and policymakers with the necessary insights to address the HCV burden more effectively. We aimed to highlight the progress made in managing and preventing HCV infection and to highlight the persistent barriers challenging the prevention of HCV infection. The overarching goal was to align with global health objectives towards reducing the burden of chronic hepatitis, aiming for its eventual elimination as a public health threat by 2030.

    背景:原发性硬化性胆管炎(PSC)是一种进行性免疫介导的肝病,没有药物治疗可以减缓疾病进展。然而,新疗法的前景令人鼓舞,几项创新的临床试验正在进行中。尽管取得了这些进步,研究的结果存在相当大的异质性,对于衡量什么结果缺乏共识,何时测量以及如何测量。此外,近年来,PSC治疗目标发生了范式转变,从基于生物化学的终点转移到肝纤维化的组织学评估,基于影像学的生物标志物和患者报告的结局指标。大量新的介入试验和不断发展的终点为参与评估新疗法的所有利益相关者提供了机会。为此,有必要通过开发核心结果集(COS)来协调临床试验中使用的措施.
    方法:PSC特异性COS的合成将分四个阶段进行。最初,将进行系统的文献综述,以确定以前在PSC试验中使用的结果,其次是与关键利益相关者进行的半结构化定性访谈。后者可能包括患者,临床医生,研究人员,制药行业代表、医疗保健支付者和监管机构,确定更多重要的结果。使用文献综述和利益相关者访谈产生的结果,将进行国际两轮Delphi调查,以优先考虑纳入COS的结果。最后,将召开一次共识会议,批准COS,并传播研究结果,供未来PSC试验应用.
    背景:本研究已获得东米德兰兹-莱斯特中央研究伦理委员会(Ref:24/EM/0126)的伦理批准。这项研究的COS将广泛传播,包括在同行评审的期刊上发表。国际会议,通过患者支持小组进行推广,并在有效性试验的核心结果衡量(COMET)数据库中提供。
    背景:1239。
    BACKGROUND: Primary sclerosing cholangitis (PSC) is a progressive immune-mediated liver disease, for which no medical therapy has been shown to slow disease progression. However, the horizon for new therapies is encouraging, with several innovative clinical trials in progress. Despite these advancements, there is considerable heterogeneity in the outcomes studied, with lack of consensus as to what outcomes to measure, when to measure and how to measure. Furthermore, there has been a paradigm shift in PSC treatment targets over recent years, moving from biochemistry-based endpoints to histological assessment of liver fibrosis, imaging-based biomarkers and patient-reported outcome measures. The abundance of new interventional trials and evolving endpoints pose opportunities for all stakeholders involved in evaluating novel therapies. To this effect, there is a need to harmonise measures used in clinical trials through the development of a core outcome set (COS).
    METHODS: Synthesis of a PSC-specific COS will be conducted in four stages. Initially, a systematic literature review will be performed to identify outcomes previously used in PSC trials, followed by semistructured qualitative interviews conducted with key stakeholders. The latter may include patients, clinicians, researchers, pharmaceutical industry representatives and healthcare payers and regulatory agencies, to identify additional outcomes of importance. Using the outcomes generated from the literature review and stakeholder interviews, an international two-round Delphi survey will be conducted to prioritise outcomes for inclusion in the COS. Finally, a consensus meeting will be convened to ratify the COS and disseminate findings for application in future PSC trials.
    BACKGROUND: Ethical approval has been granted by the East Midlands-Leicester Central Research Ethics Committee (Ref: 24/EM/0126) for this study. The COS from this study will be widely disseminated including publication in peer-reviewed journals, international conferences, promotion through patient-support groups and made available on the Core Outcomes Measurement in Effectiveness Trials (COMET) database.

    背景:慢性急性肝衰竭(ACLF)是一种流行且危及生命的肝脏疾病,短期死亡率高。尽管最近关于使用间充质干细胞(MSCs)进行ACLF治疗的临床试验显示了有希望的结果,多中心随机对照II期临床试验仍然不常见.该试验的主要目的是评估不同MSC治疗ACLF的安全性和有效性。
    方法:这是一个多中心,双盲,两阶段,随机和安慰剂对照临床试验。在第一阶段,150名ACLF患者将被纳入并随机分配到对照组(50例)或MSC治疗组(100例)。他们将接受安慰剂或脐带衍生的MSC(UC-MSC)治疗三次(在第0、1和2周)。在第二阶段,第一次UC-MSCs输注后28天,MSC治疗组中存活的患者将进一步以1:1的比例随机分为MSC-短和MSC-长的组。他们将在第4周和第5周接受另外两轮安慰剂或UC-MSC治疗。主要终点是无移植存活率和治疗相关不良事件的发生率。次要终点包括国际标准化比率,总胆红素,血清白蛋白,血尿素氮,终末期肝病评分和Child-Turcotte-Pugh评分的模型。
    背景:这项研究已从中国人民解放军总医院第五医学中心获得伦理批准(KY-2023-3-19-1)。研究的所有结果将提交给国际期刊和国际会议,以便在研究完成后发表。
    背景:NCT05985863。
    BACKGROUND: Acute-on-chronic liver failure (ACLF) is a prevalent and life-threatening liver disease with high short-term mortality. Although recent clinical trials on the use of mesenchymal stem cells (MSCs) for ACLF treatment have shown promising results, multicentre randomised controlled phase II clinical trials remain uncommon. The primary aim of this trial is to assess the safety and efficacy of different MSCs treatment courses for ACLF.
    METHODS: This is a multicentre, double-blind, two-stage, randomised and placebo-controlled clinical trial. In the first stage, 150 patients with ACLF will be enrolled and randomly assigned to either a control group (50 cases) or an MSCs treatment group (100 cases). They will receive either a placebo or umbilical cord-derived MSCs (UC-MSCs) treatment three times (at weeks 0, 1 and 2). In the second stage, 28 days after the first UC-MSCs infusion, surviving patients in the MSCs treatment group will be further randomly divided into MSCs-short and MSCs-prolonged groups at a 1:1 ratio. They will receive two additional rounds of placebo or UC-MSCs treatment at weeks 4 and 5. The primary endpoints are the transplant-free survival rate and the incidence of treatment-related adverse events. Secondary endpoints include international normalised ratio, total bilirubin, serum albumin, blood urea nitrogen, model for end-stage liver disease score and Child-Turcotte-Pugh score.
    BACKGROUND: Ethical approval of this study has been obtained from the Fifth Medical Center of the Chinese PLA General Hospital (KY-2023-3-19-1). All results of the study will be submitted to international journals and international conferences for publication on completion of the study.

    背景:ISRCTN14411809。
    OBJECTIVE: The study aimed to assess the feasibility, acceptability and safety of delivering a home-based telehealth exercise intervention to older patients with hepatocellular carcinoma (HCC).
    METHODS: Non-randomised feasibility study.
    METHODS: Patients were recruited from UK outpatient liver cancer clinics.
    METHODS: Patients were aged ≥60 years with HCC, with post-treatment imaging reporting a complete response, partial response or stable disease.
    UNASSIGNED: Patients were invited to attend synchronous online exercise sessions, twice weekly for 10 weeks. Physical function and patient-reported outcomes were assessed pre-intervention and post-intervention. Qualitative data were collected via semistructured interviews after intervention completion.
    METHODS: Recruitment, retention, exercise adherence and safety.
    RESULTS: 40 patients were invited to participate and 19 (mean age 74 years) provided consent (recruitment rate 48%). Patients completed 76% of planned exercise sessions and 79% returned to the clinic for follow-up. Hand grip strength (95% CI 1.0 to 5.6), Liver Frailty Index (95% CI -0.46 to -0.23) and time taken to perform five sit-to-stands (95% CI -3.2 to -1.2) improved from pre-intervention to post-intervention. Patients reported that concerns they had relating to their cancer had improved following the intervention (95% CI 0.30 to 5.85). No adverse events occurred during exercise sessions.Qualitative data highlighted the importance of an instructor in real time to ensure that the sessions were achievable, tailored and well balanced, which helped to foster motivation and commitment within the group. Patients reported enjoying the exercise intervention, including the benefits of peer support and highlighted perceived benefits to both their physical and mental health. Patients felt that the online sessions overcame some of the barriers to exercise participation and preferred attending virtual sessions over face-to-face classes.
    CONCLUSIONS: It is feasible, acceptable and safe to deliver supervised group exercise via videoconferencing to patients with HCC in their own homes. These findings will inform the design of a future, adequately powered randomised controlled trial to evaluate the efficacy of the intervention.

    原发性硬化性胆管炎(PSC)是一种进行性胆汁淤积性肝病,没有许可的治疗方法。先前的全基因组关联研究(GWAS)已经确定了与PSC显着相关的基因,这些是通过系统审查确定的。在这里,我们使用新的网络邻近分析(NPA)方法来鉴定已经获得许可的候选药物,这些药物可能对PSC病理生理学的遗传编码方面产生影响。通过该方法鉴定了超过2000种试剂与PSC中涉及的基因显著相关。最重要的结果包括以前研究过的药物,如甲硝唑,以及生物制剂如巴利昔单抗,abatacept和belatacept.这种计算机模拟分析可能作为开发这种罕见疾病的新型临床试验的基础。
    Primary Sclerosing Cholangitis (PSC) is a progressive cholestatic liver disease with no licensed therapies. Previous Genome Wide Association Studies (GWAS) have identified genes that correlate significantly with PSC, and these were identified by systematic review. Here we use novel Network Proximity Analysis (NPA) methods to identify already licensed candidate drugs that may have an effect on the genetically coded aspects of PSC pathophysiology.Over 2000 agents were identified as significantly linked to genes implicated in PSC by this method. The most significant results include previously researched agents such as metronidazole, as well as biological agents such as basiliximab, abatacept and belatacept. This in silico analysis could potentially serve as a basis for developing novel clinical trials in this rare disease.

    OBJECTIVE: Migrants from high HIV, hepatitis B virus (HBV) or hepatitis C virus (HCV) endemicity regions have a great burden of these infections and related diseases in the host countries. This study aimed to assess the predictive capacity of the Test Rapide d\'Orientation Diagnostique (TROD) Screen questionnaire for HIV, HBV and HCV infections among migrants arriving in France.
    METHODS: An observational and multicentre study was conducted among migrants. A self-questionnaire on demographic characteristics, personal medical history and sexual behaviours was completed.
    METHODS: The study was conducted in the centres of the French Office for Immigration and Integration (OFII).
    METHODS: Convenience sampling was used to select and recruit adult migrants between January 2017 and March 2020.
    METHODS: Participants were tested for HIV, HBV and HCV with rapid tests. For each infection, the test performance was assessed using receiver operating characteristics curves, using area under the curve (AUC) as a measure of accuracy.
    RESULTS: Among 21 133 regular migrants seen in OFII centres, 15 343 were included in the study. The participants\' mean age was 35.6 years (SD±11.1). The prevalence (95% CI) of HBV, HCV and HIV was 2.0% (1.8% to 2.2%), 0.3% (0.2% to 0.4%) and 0.3% (0.2% to 0.4%), respectively. Based on the sensitivity-specificity curve analysis, the cut-off points (95% CI) chosen for the risk score were: 2.5 (2.5 to 7.5) for HBV infection in men; 6.5 (0.5 to 6.5) for HBV infection in women; 9.5 (9.5 to 12.5) for HCV infection; and 10.5 (10.0 to 18.5) for HIV infection. Test performance was highest for HIV (AUC=82.15% (95% CI 74.54% to 87.99%)), followed by that for HBV in men (AUC=79.22%, (95% CI 76.18% to 82.26%)), for HBV in women (AUC=78.83 (95% CI 74.54% to 82.10%)) and that for HCV (AUC=75.95% (95% CI 68.58% to 83.32%)).
    CONCLUSIONS: The TROD screen questionnaire showed good overall performance for predicting HIV, HBV and HCV infections among migrants in OFII centres. It could be used to optimise screening for these infections and to propose rapid screening tests to those who are at high risk.

    自噬增强在脓毒症肝损伤中可以起到保护作用。没有神经,自噬介导的脓毒症肝损伤机制有待进一步研究。我们的研究表明,在败血症条件下,GLI家族锌指2(GLI2)升高,而过氧化物酶体增殖物激活受体α(PPARα)下调。在暴露于LPS的细胞中抑制GLI2或滑膜细胞凋亡抑制剂1(SYVN1)增加PPARα水平,增强细胞活力和自噬,同时抑制细胞凋亡。LPS增强GLI2-SYVN1启动子结合。SYVN1促进泛素介导的PPARα降解。IGF2BP3通过靶向其m6A位点来稳定GLI2mRNA。沉默IGF2BP3导致GLI2和SYVN1降低,但PPARα水平升高,促进细胞存活和自噬,同时抑制细胞凋亡。这被SYVN1过表达抵消。在盲肠结扎和穿刺小鼠中,IGF2BP3、SYVN1或GLI2敲低可改善肝脏损伤并增强自噬。总之,IGF2BP3增强GLI2稳定性,过表达GLI2随后通过与其启动子相互作用促进SYVN1水平,导致PPARα的泛素化降解,从而抑制PPARα介导的自噬,然后加剧脓毒症的肝损伤。
    Autophagy enhancement in septic liver injury can play a protective role. Nerveless, the mechanism of autophagy-mediated septic liver injury needs further investigation. Our study demonstrated that in septic condition, GLI Family Zinc Finger 2 (GLI2) was elevated, whereas peroxisome-proliferator-activated receptor α (PPARα) was downregulated. Suppressing GLI2 or synovialapoptosis inhibitor 1 (SYVN1) in LPS-exposed cells increased PPARα levels, enhanced cell viability and autophagy, while inhibiting apoptosis. LPS enhanced the GLI2-SYVN1 promoter binding. SYVN1 fostered ubiquitin-mediated degradation of PPARα. IGF2BP3 stabilized GLI2 mRNA by targeting its m6A site. Silencing IGF2BP3 led to decreased GLI2 and SYVN1 but increased PPARα levels, promoting cell survival and autophagy, while repressing apoptosis. This was counteracted by SYVN1 overexpression. In cecal ligation and puncture mice, IGF2BP3, SYVN1, or GLI2 knockdown ameliorated liver damage and augmented autophagy. In summary, IGF2BP3 enhanced GLI2 stability, overexpressed GLI2 subsequent promoted SYVN1 levels by interacting with its promoter, leading to ubiquitinated degradation of PPARα, thereby inhibiting PPARα-mediated autophagy and then exacerbating liver injury in sepsis.
