    未经证实:肝硬化患者常出现贫血,并被确定为不良结局的预测因子。如死亡率增加和慢性急性肝衰竭的发生。迄今为止,补充铁对这些不良结局的可能影响没有很好的描述.因此,我们旨在评估铁补充剂在肝硬化患者中的作用及其改善预后的能力。
    UNASSIGNED:对2018年7月至2019年12月在埃森大学医院收治的肝硬化连续门诊患者进行了实验室诊断。在回归模型中评估与无移植存活的关联。
    UNASSIGNED:共纳入317名肝硬化门诊患者,其中61人接受了肝移植(n=19)或死亡(n=42)。在多元Cox回归分析中,男性(危险比[HR]=3.33,95%CI[1.59,6.99],p=0.001),终末期肝病评分模型(HR=1.19,95%CI[1.11,1.27],p<0.001)和6个月内血红蛋白水平的增加(ΔHb6)(HR=0.72,95%CI[0.63,0.83],p<0.001)与无移植生存率相关。关于血红蛋白增加的预测,利福昔明的摄入(β=0.50,SDβ=0.19,p=0.007)和铁补充剂(β=0.79,SDβ=0.26,p=0.003)是多变量分析中的显著预测因子.
    UASSIGNED:在肝硬化患者中,血红蛋白水平的升高与无移植生存率的改善有关。因为血红蛋白增加的预测显著依赖于利福昔明和铁的补充,这两种药物的应用会对这些患者的预后产生重要影响。
    UNASSIGNED:贫血在肝硬化患者中非常常见,已知是阴性结果的预测因子,但是对这些个体的铁替代作用知之甚少。在我们的队列中,血红蛋白水平升高可改善肝硬化患者的无移植生存率.血红蛋白水平的增加主要是由铁补充引起的,并且在同时使用铁和利福昔明的情况下甚至更强。
    未经评估:UME-ID-10042。
    UNASSIGNED: Anaemia is frequently observed in patients with cirrhosis and was identified as a predictor of adverse outcomes, such as increased mortality and occurrence of acute-on-chronic liver failure. To date, the possible effects of iron supplementation on these adverse outcomes are not well described. We therefore aimed to assess the role of iron supplementation in patients with cirrhosis and its capability to improve prognosis.
    UNASSIGNED: Laboratory diagnostics were performed in consecutive outpatients with cirrhosis admitted between July 2018 and December 2019 to the University Hospital Essen. Associations with transplant-free survival were assessed in regression models.
    UNASSIGNED: A total of 317 outpatients with cirrhosis were included, of whom 61 received a liver transplant (n = 19) or died (n = 42). In multivariate Cox regression analysis, male sex (hazard ratio [HR] = 3.33, 95% CI [1.59, 6.99], p = 0.001), model for end-stage liver disease score (HR = 1.19, 95% CI [1.11, 1.27], p <0.001) and the increase of haemoglobin levels within 6 months (ΔHb6) (HR = 0.72, 95% CI [0.63, 0.83], p <0.001) were associated with transplant-free survival. Regarding the prediction of haemoglobin increase, intake of rifaximin (beta = 0.50, SD beta = 0.19, p = 0.007) and iron supplementation (beta = 0.79, SD beta = 0.26, p = 0.003) were significant predictors in multivariate analysis.
    UNASSIGNED: An increase of haemoglobin levels is associated with improvement of transplant-free survival in patients with cirrhosis. Because the prediction of haemoglobin increase significantly depends on rifaximin and iron supplementation, application of these two medications can have an important impact on the outcome of these patients.
    UNASSIGNED: Anaemia is very common in patients with cirrhosis and is known to be a predictor of negative outcomes, but little is known about the effect of iron substitution in these individuals. In our cohort, increase of haemoglobin levels improved transplant-free survival of patients with cirrhosis. The increase of haemoglobin levels was mainly induced by iron supplementation and was even stronger in the case of concomitant use of iron and rifaximin.
    UNASSIGNED: UME-ID-10042.

    未经证实:在患有Child-PughB肝硬化和急性静脉曲张破裂出血(AVB)的个体中,BavenoVII研讨会建议Child-Pugh评分为8~9分,初次内镜检查时出现活动性出血(ChildB8-9+AB标准)的患者采用先发制人TIPS.然而,该标准是否优于CLIF-Consortium急性失代偿评分(CLIF-CAD)尚不清楚.
    UNASSIGNED:回顾性分析了来自中国13家大学医院的1,021例Child-PughB肝硬化和AVB患者的数据,这些患者接受了先发制人TIPS(n=297)或药物加内镜治疗(n=724)2010年至2019年之间。在校正混杂因素后,使用竞争风险回归模型比较两组之间的结果。使用获益一致性统计量(c-for-benefit)评估模型预测治疗获益的能力(治疗组之间的风险差异)。
    UNASSIGNED:与药物加内镜治疗相比,先发制人TIPS与死亡率降低相关(校正风险比0.62,95%CI0.44至0.88)。较高的基线CLIF-CAD评分与更大的生存获益相关(即,更大的绝对死亡率风险降低)。在调整了混杂因素后,在CLIF-CADs≥48或Child-PughB8-9伴活动性出血的个体中观察到生存获益,但在CILF-CAD<48、无活动性出血或Child-PughB7伴活动性出血的患者中没有。CILF-CAD预测生存获益的获益率高于儿童B8-9+AB标准。
    未经证实:在患有Child-PughB肝硬化和AVB的个体中,CLIF-CAD预测先发制人TIPS的生存益处,优于儿童B8-9+AB标准。应进行前瞻性验证以确认此结果,尤其是肝硬化的其他病因。
    未经批准:在这项研究中,在Child-PughB肝硬化和急性静脉曲张破裂出血的个体中,CLIF-Consortium急性失代偿(CLIF-CAD)评分可以预测先发制人TIPS的生存获益,CLIF-CAD评分较高的患者从抢先性TIPS中获益更多。此外,CLIF-CAD评分优于儿童B8-9加上活动性出血标准,在区分那些获得更多益处的人与从先发制人的提示中获益较少。根据前瞻性验证,CLIF-CAD评分可作为选择模型,用于确定谁应该接受抢先TIPS.
    UNASSIGNED: Among individuals with Child-Pugh B cirrhosis and acute variceal bleeding (AVB), the Baveno VII workshop recommended pre-emptive TIPS in those with a Child-Pugh score of 8-9 and active bleeding at initial endoscopy (Child B8-9 + AB criteria). Nevertheless, whether this criterion is superior to the CLIF-Consortium acute decompensation score (CLIF-C ADs) remains unclear.
    UNASSIGNED: Data on 1,021 consecutive individuals with Child-Pugh B cirrhosis and AVB from 13 university hospitals in China who were treated with pre-emptive TIPS (n = 297) or drug plus endoscopic treatment (n = 724) between 2010 to 2019 were retrospectively analysed. A competing risk regression model was used to compare the outcomes between the two groups after adjusting for confounders. The concordance-statistic for benefit (c-for-benefit) was used to evaluate a models\' ability to predict treatment benefit (risk difference between treatment groups).
    UNASSIGNED: Pre-emptive TIPS was associated with reduced mortality compared to drug plus endoscopic treatment (adjusted hazard ratio 0.62, 95% CI 0.44 to 0.88). A higher baseline CLIF-C AD score was associated with greater survival benefit (i.e., larger absolute mortality risk reduction). After adjusting for confounders, a survival benefit was observed in individuals with CLIF-C ADs ≥48 or Child-Pugh B8-9 with active bleeding, but not in those with CILF-C ADs <48, no active bleeding or Child-Pugh B7 with active bleeding. The c-for-benefit of CILF-C ADs for predicting survival benefit was higher than that of Child B8-9+AB criteria.
    UNASSIGNED: In individuals with Child-Pugh B cirrhosis and AVB, CLIF-C ADs predicts survival benefit from pre-emptive TIPS and outperforms the Child B8-9+AB criteria. Prospective validation should be performed to confirm this result, especially for other aetiologies of cirrhosis.
    UNASSIGNED: In this study, among individuals with Child-Pugh B cirrhosis and acute variceal bleeding, the CLIF-Consortium acute decompensation (CLIF-C AD) score could predict the survival benefit from pre-emptive TIPS, with patients with higher CLIF-C AD scores benefiting more from pre-emptive TIPS. Furthermore, the CLIF-C AD score outperformed the Child B8-9 plus active bleeding criteria in terms of discriminating between those who obtained more benefit vs. less benefit from pre-emptive TIPS. Depending on prospective validation, the CLIF-C AD score could be used as the model of choice to determine who should undergo pre-emptive TIPS.

    急性对慢性肝衰竭(ACLF)是发生在肝硬化患者的临床综合征,其特征是急性恶化,器官衰竭和高短期死亡率。酒精是ACLF的主要原因之一,也是最常见的慢性肝病的病因。在酒精性肝炎(AH)患者中,ACLF是一种常见且严重的并发症。其特征在于与感染风险增加相关的免疫功能障碍和最终诱导器官衰竭的高级全身性炎症。ACLF的诊断和严重程度决定AH预后,因此,ACLF预后评分应用于有器官衰竭的严重AH。皮质类固醇仍然是严重AH的一线治疗,但当ACLF相关时,它们似乎不足。已经确定并正在研究包含过度炎症反应和减少感染的新治疗靶标。肝移植仍然是严重AH和ACLF最有效的治疗方法之一,适当的器官分配是一个日益严峻的挑战。因此,对病理生理学有清晰的认识,AH中ACLF的临床意义和管理策略对肝病学家至关重要,在这篇综述中简要叙述了这一点。
    Acute-on-chronic liver failure (ACLF) is a clinical syndrome that occurs in patients with cirrhosis and is characterised by acute deterioration, organ failure and high short-term mortality. Alcohol is one of the leading causes of ACLF and the most frequently reported aetiology of underlying chronic liver disease. Among patients with alcoholic hepatitis (AH), ACLF is a frequent and severe complication. It is characterised by both immune dysfunction associated to an increased risk of infection and high-grade systemic inflammation that ultimately induce organ failure. Diagnosis and severity of ACLF determine AH prognosis, and therefore, ACLF prognostic scores should be used in severe AH with organ failure. Corticosteroids remain the first-line treatment for severe AH but they seem insufficient when ACLF is associated. Novel therapeutic targets to contain the excessive inflammatory response and reduce infection have been identified and are under investigation. With liver transplantation remaining one of the most effective therapies for severe AH and ACLF, adequate organ allocation represents a growing challenge. Hence, a clear understanding of the pathophysiology, clinical implications and management strategies of ACLF in AH is essential for hepatologists, which is narrated briefly in this review.

    尽管腹水是肝硬化中最常见的第一失代偿事件,作为单指标失代偿的腹水后的临床病程尚不明确。因此,这项多中心研究的目的是系统地研究腹水作为第一个失代偿事件后进一步失代偿的发生率和类型,并评估死亡的危险因素。
    在2003年至2021年期间,在2所大学医院(帕多瓦和维也纳)共纳入622例肝硬化患者,其中2/3级腹水作为单指标失代偿事件。进一步失代偿的事件,肝移植,并记录死亡。
    平均年龄为57±11岁,大多数患者为男性(n=423,68%),酒精相关(n=366,59%)和病毒性(n=200,32%)肝病为主要病因。总的来说,323例(52%)患者表现为2级和299例(48%)3级腹水。演示时Child-Pugh评分中位数为8(IQR7-9),终末期肝病(MELD)的平均模型为15±6。在49个月的中位随访期间,350例(56%)患者经历了进一步的代偿失调:顽固性腹水(n=130,21%),肝性脑病(n=112,18%),自发性细菌性腹膜炎(n=32,5%),肝肾综合征-急性肾损伤(n=29,5%)。静脉曲张出血作为孤立的进一步失代偿事件是罕见的(n=18,3%),而非出血的进一步失代偿(n=161,26%)和≥2次伴随的进一步失代偿事件(n=171,27%)是常见的.仅81例(13%)患者使用了经颈静脉肝内门体分流术。在出现2级腹水的患者中,MELD≥15表明进一步失代偿的相当大风险(子分布风险比[SHR]2.18;p<0.001;1年发病率:<10:10%vs.10-14:13%vs.≥15:28%)和死亡率(SHR1.89;p=0.004;1年发病率:<10:3%vs.10-14:6%vs.≥15:14%)。重要的是,在整个3级腹水的MELD地层中,死亡率同样很高(p=n.s.对于不同的MELD地层;1年发病率:<10:14%vs.10-14:15%vs.≥15:20%)。
    腹水患者经常发生单指标代偿失调事件,很少发生出血。虽然2级腹水和MELD<15的患者似乎有良好的预后,在所有MELD地层中,3级腹水患者的死亡风险很高.
    失代偿(肝功能恶化导致的症状发展)标志着肝硬化患者病程的转折点。腹水(即,腹部积液)是最常见的第一次代偿失调事件,然而,对于将腹水发展为单一的首次失代偿事件的患者的临床过程知之甚少.在这里,我们表明,腹水的严重程度与死亡率有关,在中度腹水患者中,广泛使用的预后MELD评分可以预测患者预后.
    UNASSIGNED: Although ascites is the most frequent first decompensating event in cirrhosis, the clinical course after ascites as the single index decompensation is not well defined. The aim of this multicentre study was thus to systematically investigate the incidence and type of further decompensation after ascites as the first decompensating event and to assess risk factors for mortality.
    UNASSIGNED: A total of 622 patients with cirrhosis presenting with grade 2/3 ascites as the single index decompensating event at 2 university hospitals (Padova and Vienna) between 2003 and 2021 were included. Events of further decompensation, liver transplantation, and death were recorded.
    UNASSIGNED: The mean age was 57 ± 11 years, and most patients were male (n = 423, 68%) with alcohol-related (n = 366, 59%) and viral (n = 200,32%) liver disease as the main aetiologies. In total, 323 (52%) patients presented with grade 2 and 299 (48%) with grade 3 ascites. The median Child-Pugh score at presentation was 8 (IQR 7-9), and the mean model for end-stage liver disease (MELD) was 15 ± 6. During a median follow-up period of 49 months, 350 (56%) patients experienced further decompensation: refractory ascites (n = 130, 21%), hepatic encephalopathy (n = 112, 18%), spontaneous bacterial peritonitis (n = 32, 5%), hepatorenal syndrome-acute kidney injury (n = 29, 5%). Variceal bleeding as an isolated further decompensation event was rare (n = 18, 3%), whereas non-bleeding further decompensation (n = 161, 26%) and ≥2 concomitant further decompensation events (n = 171, 27%) were frequent. Transjugular intrahepatic portosystemic shunt was used in only 81 (13%) patients. In patients presenting with grade 2 ascites, MELD ≥15 indicated a considerable risk for further decompensation (subdistribution hazard ratio [SHR] 2.18; p <0.001; 1-year incidences: <10: 10% vs. 10-14: 13% vs. ≥15: 28%) and of mortality (SHR 1.89; p = 0.004; 1-year incidences: <10: 3% vs. 10-14: 6% vs. ≥15: 14%). Importantly, mortality was similarly high throughout MELD strata in grade 3 ascites (p = n.s. for different MELD strata; 1-year incidences: <10: 14% vs. 10-14: 15% vs. ≥15: 20%).
    UNASSIGNED: Further decompensation is frequent in patients with ascites as a single index decompensation event and only rarely owing to bleeding. Although patients with grade 2 ascites and MELD <15 seem to have a favourable prognosis, those with grade 3 ascites are at a high risk of mortality across all MELD strata.
    UNASSIGNED: Decompensation (the development of symptoms as a result of worsening liver function) marks a turning point in the disease course for patients with cirrhosis. Ascites (i.e. , the accumulation of fluid in the abdomen) is the most common first decompensating event, yet little is known about the clinical course of patients who develop ascites as a single first decompensating event. Herein, we show that the severity of ascites is associated with mortality and that in patients with moderate ascites, the widely used prognostic MELD score can predict patient outcomes.

    缺乏接受包括单独抗凝在内的药物治疗的Budd-Chairi综合征(BCS)患者的长期预后数据。
    连续患者(N=138,平均值[标准差,SD]年龄29.3[12.9]岁;66名男性)患有BCS,仅接受药物治疗,包括抗凝治疗,纳入最少随访12个月.初始反应被分类为完全(CR),部分(PR)或无应答(NR),并作为应答丧失(LoR)或应答维持(MoR)进行随访。基线的关联,评估了具有不同反应的临床和生化参数.
    76例患者(55.1%)有CR,26例(18.8%)有PR,36例(26.1%)有NR。具有PR或NR的人后来都没有CR。在中位随访40(范围12-174)个月时,LoR在PR组比CR组更常见(12[46.2%]vs18[23.7%],P=0.03)。LoR与腹水的存在相关(比值比[OR]1.5;95%置信区间[CI]0.06-0.71),基线和随访期间的胃肠道出血(OR1.33;95%CI0.09-0.82)或黄疸(OR1.01;95%CI0.11-0.97)(OR0.018;95%CI1.006-1.030)。NR(28[77.8%])死亡率高于CR(15[19.7%],P=0.001)和PR(8[30.8%],P=0.001)。在二元逻辑回归分析中,基线时腹水的存在与LoR相关(OR0.303[0.098-0.931]).
    初始CR患者的生存率优于无反应者。三分之一的人在后续行动中有LoR。基线时腹水的存在与LoR相关。
    UNASSIGNED: There is lack of data on long-term outcomes of patients with Budd-Chairi Syndrome (BCS) treated with medical therapy including anticoagulation alone.
    UNASSIGNED: Consecutive patients (N = 138, mean [standard deviation, SD] age 29.3 [12.9] years; 66 men) with BCS, treated with medical therapy alone including anticoagulation, with minimum follow-up of 12 months were included. Initial response was classified as complete (CR), partial (PR) or nonresponse (NR) and on follow-up as loss of response (LoR) or maintenance of response (MoR). The association of baseline, clinical and biochemical parameters with different responses was evaluated.
    UNASSIGNED: Seventy-six patients (55.1%) had CR, 26 (18.8%) had PR and 36 (26.1%) had NR. None with PR or NR had CR later. At a median follow-up of 40 (range 12-174) months, LoR was more common in PR group than in CR group (12 [46.2%] vs 18 [23.7%], P = 0.03). LoR was associated with presence of ascites (odds ratio [OR] 1.5; 95% confidence interval [CI] 0.06-0.71), gastrointestinal bleed (OR 1.33; 95% CI 0.09-0.82) or jaundice (OR 1.01; 95% CI 0.11-0.97) at baseline and duration of follow-up (OR 0.018; 95% CI 1.006-1.030). Mortality was higher in NR (28 [77.8%]) compared with CR (15 [19.7%], P = 0.001) and PR (8 [30.8%], P = 0.001). On binary logistic regression analysis, presence of ascites at baseline was associated with LoR (OR 0.303 [0.098-0.931]).
    UNASSIGNED: Patients with initial CR have better survival than nonresponders. One-third had LoR on follow-up. The presence of ascites at baseline is associated with LoR.

    肝脏包括具有不同功能的实质和非实质细胞。肝硬化通常因门脉高压的发展及其相关并发症而复杂化。因此,肝硬化的评估应包括其结构的评估,肝组织和非肝组织的功能和门静脉高压症的血流动力学评估。没有单一的测试可以评估所有肝功能并评估门静脉高压症的患病率和严重程度。常见的测试,如血清胆红素,肝酶(丙氨酸[ALT]和天冬氨酸氨基转移酶[AST],血清碱性磷酸酶γ谷氨酰转肽酶[GGT]),血清白蛋白和凝血酶原时间评估肝功能部分评估肝功能。定量肝功能,如吲哚菁清除试验[ICG-K],美沙西丁呼气试验[MBT]用于评估肝脏的动态状态,但有其自身的局限性和可用性。通过瞬时弹性成像评估肝脏,基于MRI的99mTc偶联脱唾液酸糖蛋白美溴芬素扫描有助于临床医生评估肝功能,手术后留下的肝脏功能容量和门静脉高压[PH]。肝静脉压力梯度仍然是评估门静脉高压的金标准,但具有侵入性,并非在所有中心都可用。各种指标形式的血液参数组合,如纤维化评分4[FIB-4],Lok指数,终末期肝病模型(MELD)和Child-TurcottePugh评分等评分在临床实践中通常用于评估肝功能。
    The liver comprises both parenchymal and non-parenchymal cells with varying functions. Cirrhosis is often complicated by the development of portal hypertension and its associated complications. Hence, assessment of liver in cirrhosis should include assessment of its structural, function of both hepatic and non-hepatic tissue and haemodynamic assessment of portal hypertension. There is no single test that can evaluate all functions of liver and assess prevalence and severity of portal hypertension. Commonly available tests like serum bilirubin, liver enzymes (alanine [ALT] and aspartate aminotransferase [AST], serum alkaline phosphatase [ALP], gamma glutamyl transpeptidase [GGT]), serum albumin and prothrombin time for assessment of liver functions partly assess liver functions. quantitative liver functions like indocyanine clearance tests [ICG-K], methacetin breath test [MBT] were developed to assess dynamic status of liver but has its own limitation and availability. Imaging based assessment of liver by transient elastography, MRI based 99 mTc-coupled asialoglycoprotein mebrofenin scan help the clinician to assess liver function, functional volume of liver left after surgery and portal hypertension [PH]. Hepatic venous pressure gradient still remains the gold standard for the assessment of portal hypertension but is invasive and not available in all centres. Combinations of blood parameters in form of various indices like fibrosis score of 4 [FIB-4], Lok index, scores like model for end stage liver disease (MELD) and Child-Turcotte Pugh score are commonly used for assessing liver function in clinical practice.

    目的:含Ig结构域的V-set4(VSIG4)是一种免疫调节性巨噬细胞补体受体,可调节先天和适应性免疫,并影响细菌感染的解决。鉴于其在腹膜巨噬细胞(PMs)上的表达,我们假设腹膜VSIG4浓度在自发性细菌性腹膜炎(SBP)患者中的预后作用.
    方法:我们从肝硬化患者中分离PMs,并通过流式细胞术分析VSIG4表达和释放,实时定量PCR,ELISA,和共聚焦显微镜。我们测量了120例SBP患者和40例无SBP患者的腹水中可溶性VSIG4浓度,并使用Kaplan-Meier统计方法研究了腹水中可溶性VSIG4与SBP后90天生存率的关系。Cox回归,和竞争风险回归分析。
    结果:静息时VSIG4表达高,大型PM,共表达CD206,CD163和酪氨酸蛋白激酶Mer(MERTK)。SBP患者PMs中VSIG4基因表达降低,消退后恢复正常。在SBP期间,VSIG4hiPM耗尽(25%与57%;p<0.001),腹水中的可溶性VSIG4在SBP患者中高于无SBP患者(0.73vs.0.35μg/ml;p<0.0001)。通过Toll样受体(TLR)激动剂或体外活细菌感染的PM活化导致表面VSIG4的丧失和可溶性VSIG4的释放。机械上,PM中VSIG4的脱落是蛋白酶依赖性的,并且容易受到微管运输抑制。腹水中可溶性VSIG4超过血清浓度,并与血清肌酐相关,SBP期间终末期肝病评分和C反应蛋白的模型。1.0206μg/ml或更高的浓度表明90天死亡率增加(风险比1.70;95%CI1.01-2.86;p=0.046)。
    结论:在SBP期间,VSIG4从活化的PMs释放到腹水中。较高的腹膜VSIG4水平表明患者具有器官衰竭和不良预后。
    背景:发生腹水的肝硬化患者感染和死亡的风险增加。我们的研究表明,在感染腹水的患者中,补体受体VSIG4由常驻巨噬细胞释放到可以测量的腹液中。腹水中这种蛋白质水平升高的患者在90天内死亡的风险很高。
    OBJECTIVE: V-set Ig-domain-containing 4 (VSIG4) is an immunomodulatory macrophage complement receptor modulating innate and adaptive immunity and affecting the resolution of bacterial infections. Given its expression on peritoneal macrophages (PMs), we hypothesised a prognostic role of peritoneal VSIG4 concentrations in patients with spontaneous bacterial peritonitis (SBP).
    METHODS: We isolated PMs from patients with cirrhosis and analysed VSIG4 expression and release by flow cytometry, quantitative real-time PCR, ELISA, and confocal microscopy. We measured soluble VSIG4 concentrations in ascites from 120 patients with SBP and 40 patients without SBP and investigated the association of soluble VSIG4 in ascites with 90-day survival after SBP using Kaplan-Meier statistics, Cox regression, and competing-risks regression analysis.
    RESULTS: VSIG4 expression was high on resting, large PMs, which co-expressed CD206, CD163, and tyrosine-protein kinase Mer (MERTK). VSIG4 gene expression in PMs decreased in patients with SBP and normalised after resolution. During SBP, VSIG4hi PMs were depleted (25% vs. 57%; p <0.001) and soluble VSIG4 in ascites were higher in patients with SBP than in patients without (0.73 vs. 0.35 μg/ml; p <0.0001). PM activation by Toll-like receptor (TLR) agonists or infection with live bacteria in vitro resulted in a loss of surface VSIG4 and the release of soluble VSIG4. Mechanistically, shedding of VSIG4 from PMs was protease-dependent and susceptible to microtubule transport inhibition. Soluble VSIG4 in ascites exceeded serum concentrations and correlated with serum creatinine, model for end-stage liver disease score and C-reactive protein during SBP. Concentrations of 1.0206 μg/ml or higher indicated increased 90-day mortality (hazard ratio 1.70; 95% CI 1.01-2.86; p = 0.046).
    CONCLUSIONS: VSIG4 is released from activated PMs into ascites during SBP. Higher peritoneal VSIG4 levels indicate patients with organ failure and poor prognosis.
    BACKGROUND: Patients with liver cirrhosis who develop ascites have an increased risk of infection and mortality. Our study shows that in patients with infected ascites, the complement receptor VSIG4 is released by resident macrophages into the abdominal fluid where it can be measured. Patients with elevated levels of this protein in ascites are at high risk of dying within 90 days.

    目的:乙型肝炎病毒(HBV)感染是世界上主要的健康问题。理发师应对尖锐设备造成的频繁擦伤/撕裂,使他们成为高危人群。确定HBsAg阳性状态排除了人群中大多数传播库。然而,隐匿性乙型肝炎仍然是传播源。这项研究的目的是研究为武装部队客户服务的理发师隐匿性HBV感染的患病率,并评估他们对HBV传播的知识和预防措施。
    方法:本研究包括79名HBsAg阴性理发师,并对免疫接种和预防措施的状况进行了访谈。抗HBc总和HBVDNA水平与完整的血象一起测量,LFT,PTINR,超声腹部和肝脏的Fibroscan。
    结果:隐匿性乙型肝炎的患病率为3.79%。在抗HBc总阳性的理发师中,100%被发现有复制HBVDNA状态。所有理发师(100%)都不知道HBV传播的存在和模式,从未进行过HBV筛查;98.73%的理发师遵循不当的消毒做法,从未进行过免疫接种。
    结论:理发师隐匿性HBV感染的患病率,没有免疫接种,无意识和不适当的消毒做法很容易传播给不知情的客户。教育理发师很重要,建立通用消毒程序,并在贸易工作开始之前实施强制乙型肝炎疫苗接种制度。
    OBJECTIVE: Hepatitis B virus (HBV) infection is a major health problem in the world. Barbers deal with frequent abrasions/lacerations due to sharp equipment, making them a high-risk group. Determination of HBsAg positive status excludes most reservoirs of transmission in the population. However, Occult Hepatitis B continues to be a source of transmission. The aim of this study was to study the prevalence of occult HBV infection in barbers serving the armed forces clientele and evaluate their knowledge and preventive practices against HBV transmission.
    METHODS: Seventy-nine HBsAg negative barbers were included in this study and interviewed for the status of immunisation and preventive practices. Anti-HBc total and HBV DNA levels were measured along with a complete haemogram, LFT, PT INR, ultrasound abdomen and Fibroscan of the liver.
    RESULTS: The prevalence of occult Hepatitis B status was 3.79%. Among barbers who were anti-HBc total positive, 100% were found to have replicative HBV DNA status. All barbers (100%) were unaware of the existence and modes of HBV transmission and were never screened for HBV; 98.73% of barbers followed improper disinfection practices and were never immunised.
    CONCLUSIONS: The prevalence of occult HBV infection in barbers, absence of immunisation, unawareness and improper disinfection practices are significantly at risk for transmission to the unaware clients. It is important to educate barbers, establish a universal disinfection procedure and implement a system of compulsory Hepatitis B vaccination before the commencement of their trade work.

    慢性急性肝衰竭(ACLF)的特征是器官衰竭,短期死亡率高,and,病理生理上,紊乱的炎症反应。细胞外基质(ECM)与炎症反应的调节密切相关。本研究旨在确定ACLF中ECM更新的生物标志物的改变及其与炎症的关联。器官衰竭,和死亡率。
    我们研究了283例因患有或不患有ACLF的急性代偿失调(AD)而入院的肝硬化患者,64例稳定期肝硬化患者,和30个健康对照。一个验证队列(25ACLF,包括9名健康对照)。测量血浆PRO-C3、PRO-C4、PRO-C5、PRO-C6和PRO-C8(即III-VI型和VIII型胶原形成)以及C4M和C6M(即IV型和VI型胶原降解)。对肝脏活检进行PRO-C6的免疫组织化学(AD[n=7],ACLF[n=5])。进行竞争风险回归分析以探索具有28天和90天死亡率的ECM更新的生物标志物的预后价值。
    与AD相比,ACLF中的PRO-C3和PRO-C6增加(分别为p=0.089和p<0.001),而胶原降解标志物C4M和C6M相似。PRO-C3和PRO-C6均与肝功能和炎症标志物密切相关。仅PRO-C6与肝外器官衰竭和28天和90天死亡率相关(风险比[HR;对数标度]6.168,95%CI2.366-16.080,p<0.001,和3.495,95%CI1.509-8.093,p=0.003,分别)。这些发现在验证队列中是一致的。在ACLF患者的肝活检中观察到高PRO-C6表达。
    这项研究表明,第一次,ACLF中严重的间质胶原净沉积的证据,并对PRO-C6与(肝外)器官衰竭和死亡率之间的关联进行了新的观察。需要进一步的研究来确定这些观察的致病意义。
    本研究描述了在慢性急性肝衰竭(ACLF)中III型和VI型胶原蛋白的更新中断。这些胶原蛋白的血浆生物标志物(PRO-C3和PRO-C6)与肝功能障碍和炎症的严重程度有关。PRO-C6,也称为激素内毒素,还发现与急性代偿失调和ACLF的多器官功能衰竭和预后有关。
    UNASSIGNED: Acute-on-chronic liver failure (ACLF) is characterised by organ failure(s), high short-term mortality, and, pathophysiologically, deranged inflammatory responses. The extracellular matrix (ECM) is critically involved in regulating the inflammatory response. This study aimed to determine alterations in biomarkers of ECM turnover in ACLF and their association with inflammation, organ failures, and mortality.
    UNASSIGNED: We studied 283 patients with cirrhosis admitted for acute decompensation (AD) with or without ACLF, 64 patients with stable cirrhosis, and 30 healthy controls. A validation cohort (25 ACLF, 9 healthy controls) was included. Plasma PRO-C3, PRO-C4, PRO-C5, PRO-C6, and PRO-C8 (i.e. collagen type III-VI and VIII formation) and C4M and C6M (i.e. collagen type IV and VI degradation) were measured. Immunohistochemistry of PRO-C6 was performed on liver biopsies (AD [n = 7], ACLF [n = 5]). A competing-risk regression analysis was performed to explore the prognostic value of biomarkers of ECM turnover with 28- and 90-day mortality.
    UNASSIGNED: PRO-C3 and PRO-C6 were increased in ACLF compared to AD (p = 0.089 and p <0.001, respectively), whereas collagen degradation markers C4M and C6M were similar. Both PRO-C3 and PRO-C6 were strongly associated with liver function and inflammatory markers. Only PRO-C6 was associated with extrahepatic organ failures and 28- and 90-day mortality (hazard ratio [HR; on log-scale] 6.168, 95% CI 2.366-16.080, p <0.001, and 3.495, 95% CI 1.509-8.093, p = 0.003, respectively). These findings were consistent in the validation cohort. High PRO-C6 expression was observed in liver biopsies of patients with ACLF.
    UNASSIGNED: This study shows, for the first time, evidence of severe net interstitial collagen deposition in ACLF and makes the novel observation of the association between PRO-C6 and (extrahepatic) organ failures and mortality. Further studies are needed to define the pathogenic significance of these observations.
    UNASSIGNED: This study describes a disrupted turnover of collagen type III and VI in Acute-on-chronic liver failure (ACLF). Plasma biomarkers of these collagens (PRO-C3 and PRO-C6) are associated with the severity of liver dysfunction and inflammation. PRO-C6, also known as the hormone endotrophin, has also been found to be associated with multi-organ failure and prognosis in acute decompensation and ACLF.
