失代偿期肝硬化
  • 文章类型: Journal Article
    目的:慢性丙型肝炎(CHC)相关的失代偿期肝硬化与较低的SVR-12发生率和直接作用抗病毒药物(DAA)后疾病严重程度的变量回归相关。我们评估了SVR-12、再补偿率(BavenoVII标准)、以及这些患者的生存。
    方法:在2018年7月至2023年7月之间,DAAs治疗后失代偿性CHC相关性肝硬化患者,对SVR-12进行评估,然后进行6个月的随访。
    结果:在6516例肝硬化患者中,1152例失代偿期肝硬化(年龄53.2±11.5岁,63%的男性,MELD-Na:16.5±4.6,87%基因型3)入组。一个疗程后SVR-12为81.8%;额外治疗后最终SVR为90.8%。失代偿事件包括腹水(1098,95.3%),肝性脑病(191,16.6%),静脉曲张出血(284,24.7%)。86%的腹水消退(24%的患者实现利尿剂戒断)。再补偿发生在284(24.7%),中位时间为16.5(IQR-14.5-20.5)个月。关于多变量Cox比例风险分析,低胆红素(aHR-0.6,95CI-0.5-0.8,P<0.001),INR(aHR-0.2,95CI:0.1-0.3,P<0.001),没有大的食管静脉曲张(aHR-0.4,95CI:0.2-0.9,P=0.048),或胃静脉曲张(aHR-0.5,95CI:0.3-0.7,P=0.022)可预测再补偿。门脉高压症(PHT)进展158例(13.7%),4%的患者再出血。既往代偿失调伴静脉曲张破裂出血(aHR-1.6,95CI:1.2-2.8,P=0.042),大静脉曲张的存在(aHR-2.9,95CI:1.3-6.5,P<0.001)与PHT进展相关。在221例(19%)中发现了进一步的代偿失调;145例患者死亡,6例接受了肝移植。MELDNa下降≥3的是409(35.5%),最终MELDNa评分<10的是335(29%),但尽管有SVR-12,但仍有2.9%的人发展为HCC。
    结论:SVR-12在HCV相关的失代偿期肝硬化中占主导地位的基因型3人群中,在公共卫生环境中,在4年的随访中,24.7%的患者获得了再补偿。尽管SVR-12,新的肝失代偿发展在19%和HCC发展在2.9%的患者。
    OBJECTIVE: Chronic hepatitis C-related decompensated cirrhosis is associated with lower sustained virologic response (SVR)-12 rates and variable regression of disease severity after direct-acting antiviral agents. We assessed rates of SVR-12, recompensation (Baveno VII criteria), and survival in such patients.
    METHODS: Between July 2018 and July 2023, patients with decompensated chronic hepatitis C-related cirrhosis after direct-acting antiviral agents treatment were evaluated for SVR-12 and then had 6-monthly follow-up.
    RESULTS: Of 6516 patients with cirrhosis, 1152 with decompensated cirrhosis (age 53.2 ± 11.5 years; 63% men; Model for End-stage Liver Disease-Sodium [MELD-Na]: 16.5 ± 4.6; 87% genotype 3) were enrolled. SVR-12 was 81.8% after 1 course; ultimately SVR was 90.8% after additional treatment. Decompensation events included ascites (1098; 95.3%), hepatic encephalopathy (191; 16.6%), and variceal bleeding (284; 24.7%). Ascites resolved in 86% (diuretic withdrawal achieved in 24% patients). Recompensation occurred in 284 (24.7%) at a median time of 16.5 (interquartile range, 14.5-20.5) months. On multivariable Cox proportional hazards analysis, low bilirubin (aHR, 0.6; 95% confidence interval [CI], 0.5-0.8; P < 0.001), INR (aHR, 0.2; 95% CI, 0.1-0.3; P < 0.001), absence of large esophageal varices (aHR, 0.4; 95% CI, 0.2-0.9; P = 0.048), or gastric varices (aHR, 0.5; 95% CI, 0.3-0.7; P = 0.022) predicted recompensation. Portal hypertension progressed in 158 (13.7%) patients, with rebleed in 4%. Prior decompensation with variceal bleeding (aHR, 1.6; 95% CI, 1.2-2.8; P = 0.042), and presence of large varices (aHR, 2.9; 95% CI, 1.3-6.5; P < 0.001) were associated with portal hypertension progression. Further decompensation was seen in 221 (19%); 145 patients died and 6 underwent liver transplantation. A decrease in MELDNa of ≥3 was seen in 409 (35.5%) and a final MELDNa score of <10 was seen in 335 (29%), but 2.9% developed hepatocellular carcinoma despite SVR-12.
    CONCLUSIONS: SVR-12 in hepatitis C virus-related decompensated cirrhosis in a predominant genotype 3 population led to recompensation in 24.7% of patients over a follow-up of 4 years in a public health setting. Despite SVR-12, new hepatic decompensation evolved in 19% and hepatocellular carcinoma developed in 2.9% of patients. (ClinicalTrials.gov, Number: NCT03488485).

    有关质子泵抑制剂(PPI)使用与肝性脑病(HE)之间关联的数据相互矛盾,多中心研究的数据很少。这项研究的目的是剖析PPI使用与最小(MHE)和明显HE(OHE)之间的潜在关联。
    分析了在欧洲和美国七个中心招募的肝硬化患者的数据。MHE由心理测量肝性脑病评分(PHES)定义。在用PHES测试的当天记录PPI的使用。随访患者发生OHE和死亡/肝移植。
    共纳入1,160例MELD中位数为11例的患者(Child-Pugh分期:A49%/B39%/C11%)。58%的患者使用PPI。中位随访时间为18.1个月,在此期间,230例(20%)出现了OHE发作,224例(19%)达到死亡/肝移植复合终点。在多变量分析中,PPI的使用与基线时MHE的存在和随访期间的OHE发展都不相关。这些发现在Child-PughA或B肝硬化患者的亚组分析中以及排除有OHE病史的患者后是一致的。PPI使用也与较高的OHE风险无关,有治疗指征的患者和无指征的患者均不适用。
    使用PPI与肝硬化患者HE的高风险无关。基于这些发现,目前,在普遍接受的适应症的情况下,不应禁止处方。

    UNASSIGNED: Data on the association between proton pump inhibitor (PPI) use and hepatic encephalopathy (HE) are conflicting, and data from multicentre studies are scarce. The aim of this study was to dissect the potential association between PPI use and minimal (MHE) and overt HE (OHE).
    UNASSIGNED: Data from patients with cirrhosis recruited at seven centres across Europe and the US were analysed. MHE was defined by the psychometric hepatic encephalopathy score (PHES). PPI use was recorded on the day of testing with PHES. Patients were followed for OHE development and death/liver transplantation.
    UNASSIGNED: A total of 1,160 patients with a median MELD of 11 were included (Child-Pugh stages: A 49%/B 39%/C 11%). PPI use was noted in 58% of patients. Median follow-up time was 18.1 months, during which 230 (20%) developed an OHE episode, and 224 (19%) reached the composite endpoint of death/liver transplantation. In multivariable analyses, PPI use was neither associated with the presence of MHE at baseline nor OHE development during follow-up. These findings were consistent in subgroup analyses of patients with Child-Pugh A or B cirrhosis and after excluding patients with a history of OHE. PPI use was also not associated with a higher risk of OHE, neither in patients with an indication for treatment nor in patients without an indication.
    UNASSIGNED: PPI use is not associated with a higher risk of HE in patients with cirrhosis. Based on these findings, at present, a prescription should not be prohibited in case of a generally accepted indication.

    我们的目的是探讨FFP输血与有显著凝血功能障碍的DC患者预后之间的关系。在倾向评分匹配(PSM)后,对总共693例具有明显凝血功能障碍的DC患者进行了分析,每组233例患者。接受FFP输血的患者与接受PSM常规治疗的患者相匹配。回归分析显示FFP输血在30天内无益处(HR:1.08,95%CI0.83-1.4),90天(HR:1.03,95%CI0.80-1.31)和住院(HR:1.30,95%CI0.90-1.89)死亡率,与肝功能衰竭风险增加相关(OR:3.00,95%CI1.78-5.07),肾衰竭(OR:1.90,95%CI1.13-3.18),凝血失败(OR:2.55,95%CI1.52-4.27),呼吸衰竭(OR:1.76,95%CI1.15-2.69),和循环衰竭(OR:2.15,95%CI1.27-3.64),甚至与LOSICU(β:2.61,95%CI1.59-3.62)和LOS医院(β:6.59,95%CI2.62-10.57)的延长有关。在敏感性分析中,多变量分析(HR:1.09,95CI0.86,1.38),IPTW(HR:1.11,95CI0.95-1.29)和CAPS(HR:1.09,95%CI0.86-1.38)显示FFP输注对30天死亡率没有有益影响。平滑曲线拟合显示肝功能衰竭的风险,肾衰竭和循环衰竭增加了3%,分别为2%和2%。FFP输血每增加1ml/kg。我们发现两组在第0、3、7、14天的CLIF-SOFA和MELD评分没有显着差异。与常规组相比,INR,APTT,FFP输血组TBIL显著升高,而PaO2/FiO2在14天内显著下降。总之,FFP输血对30天没有有益作用,90天,住院死亡率,与LOSICU和LOS医院的时间延长有关,肝功能衰竭的风险增加,肾衰竭,凝血失败,呼吸衰竭和循环衰竭事件。然而,大,多中心,随机对照试验,未来仍需要前瞻性队列研究和外部验证来验证FFP输血的疗效。
    We aimed to explore the association between FFP transfusion and outcomes of DC patients with significant coagulopathy. A total of 693 DC patients with significant coagulopathy were analyzed with 233 patients per group after propensity score matching (PSM). Patients who received FFP transfusion were matched with those receiving conventional therapy via PSM. Regression analysis showed FFP transfusion had no benefit in 30-day (HR: 1.08, 95% CI 0.83-1.4), 90-day (HR: 1.03, 95% CI 0.80-1.31) and in-hospital(HR: 1.30, 95% CI 0.90-1.89) mortality, associated with increased risk of liver failure (OR: 3.00, 95% CI 1.78-5.07), kidney failure (OR: 1.90, 95% CI 1.13-3.18), coagulation failure (OR: 2.55, 95% CI 1.52-4.27), respiratory failure (OR: 1.76, 95% CI 1.15-2.69), and circulatory failure (OR: 2.15, 95% CI 1.27-3.64), and even associated with prolonged the LOS ICU (β: 2.61, 95% CI 1.59-3.62) and LOS hospital (β: 6.59, 95% CI 2.62-10.57). In sensitivity analysis, multivariate analysis (HR: 1.09, 95%CI 0.86, 1.38), IPTW (HR: 1.11, 95%CI 0.95-1.29) and CAPS (HR: 1.09, 95% CI 0.86-1.38) showed FFP transfusion had no beneficial effect on the 30-day mortality. Smooth curve fitting demonstrated the risk of liver failure, kidney failure and circulatory failure increased by 3%, 2% and 2% respectively, for each 1 ml/kg increase in FFP transfusion. We found there was no significant difference of CLIF-SOFA and MELD score between the two group on day 0, 3, 7, 14. Compared with the conventional group, INR, APTT, and TBIL in the FFP transfusion group significantly increased, while PaO2/FiO2 significantly decreased within 14 days. In conclusion, FFP transfusion had no beneficial effect on the 30-day, 90-day, in-hospital mortality, was associated with prolonged the LOS ICU and LOS hospital, and the increased risk of liver failure, kidney failure, coagulation failure, respiratory failure and circulatory failure events. However, large, multi-center, randomized controlled trials, prospective cohort studies and external validation are still needed to verify the efficacy of FFP transfusion in the future.

    方法:这项研究是一个开放标签,剂量递增,单臂第一阶段审判。根据'3+3'规则,在每个群组(5.0×107、1.0×108、1.5×108或2.0×108个细胞)中以预定剂量单次注射UC-MSC。主要评估措施将包括不良事件的发生率和终末期肝病模型(MELD)评分从基线到第28天的变化。次要评估措施将在基线和每个随访点进行评估。这些措施将包括MELD评分从基线到每个随访点的变化,与失代偿期肝硬化相关的每种并发症的发生率,无肝移植生存率和肝功能衰竭的发生率,其他相关措施。所有患者均随访24个月。本研究将评估使用UC-MSCs治疗失代偿期肝硬化患者是否安全和可耐受。
    背景:该研究已获得中国人民解放军总医院的批准(批准号:2018-107-D-4)。一旦进行,这项研究的结果将发表在同行评审的期刊上.
    背景:NCT05227846。
    There are limited therapeutic options to efficiently treat patients with decompensated liver cirrhosis. This trial aims to explore the efficacy and safety of human umbilical cord-derived mesenchymal stem cells (UC-MSCs) for the treatment of patients with decompensated liver cirrhosis.
    This study is an open-label, dose-escalation, one-armed phase I trial. A single injection of UC-MSCs will be administered in a predetermined dose in each cohort (5.0×107, 1.0×108, 1.5×108 or 2.0×108 cells) according to the \'3+3\' rule. The primary evaluation measures will include the incidence of adverse events and the change in the Model for End-stage Liver Disease (MELD) score from baseline to the 28th day. Secondary evaluation measures will be evaluated at baseline and at each follow-up point. These measures will include the change in the MELD score from baseline to each follow-up point, the incidence of each complication associated with decompensated cirrhosis, liver transplant-free survival and the incidence of liver failure, among other relevant measures. All patients will be followed up for 24 months. This study will evaluate whether the use of UC-MSCs to treat patients with decompensated liver cirrhosis is safe and tolerable.
    The study has been approved by the Chinese People\'s Liberation Army General Hospital (Approval#: 2018-107-D-4). Once conducted, the results from the study will be published in a peer-reviewed journal.

    肝肾综合征-急性肾损伤(HRS-AKI)在终末期肝病患者中具有显著的发病率和死亡率。用于治疗HRS-AKI的特利加压素于2022年9月获得FDA批准。美国实施特利加压素,然而,由于缺乏关于最佳患者群体和管理模式的本地数据,以及对移植优先级的影响。INFUSE研究旨在评估在患有晚期肝病和HRS-AKI的移植候选人中连续输注特利加压素的使用。
    50名患有HRS-AKI的前瞻性患者将接受单次推注0.5mg特利加压素,然后连续输注2至8mg/天的特利加压素长达14天。队列将被列出的内容丰富,在评估中,或者有资格进行肝移植,ACLF3级,MELD≥35,血清肌酐>5.0mg/dL者将被排除.50名接受米多君加奥曲肽或去甲肾上腺素治疗HRS-AKI的患者将作为回顾性比较队列。
    INFUSE研究旨在评估特利加压素连续输注在大部分符合移植条件的HRS-AKI患者中的安全性和有效性,并提供基于美国的移植结果数据。这项新的研究设计同时减轻特利加压素不良事件,同时为患者提供肾脏益处。从而解决了HRS-AKI患者未满足的医疗需求,这些患者的治疗选择有限,并且在美国等待肝移植.
    UNASSIGNED: Hepatorenal syndrome-acute kidney injury (HRS-AKI) carries significant morbidity and mortality among those with end-stage liver disease. Bolus terlipressin for treatment of HRS-AKI received FDA approval in September 2022. US implementation of terlipressin, however, is hindered by the paucity of local data on the optimal patient population and administration mode, as well as the effect on transplant priority. The INFUSE study is designed to evaluate the use of continuous terlipressin infusion among transplant candidates with advanced liver disease and HRS-AKI.
    UNASSIGNED: Fifty prospective patients with HRS-AKI will receive a single bolus of terlipressin 0.5 mg followed by continuous infusions of terlipressin from 2 to 8 mg/day for up to 14 days. The cohort will be enriched with those listed, in evaluation, or eligible for liver transplantation, while those with ACLF grade 3, MELD ≥35, and serum creatinine >5.0 mg/dL will be excluded. Fifty patients who received midodrine plus octreotide or norepinephrine for HRS-AKI will serve as a retrospective comparator cohort.
    UNASSIGNED: The INFUSE study aims to assess the safety and efficacy of continuous terlipressin infusion among largely transplant-eligible patients with HRS-AKI, and to provide US-based data on transplant outcomes. This novel study design simultaneously mitigates terlipressin adverse events while providing renal benefits to patients, thus addressing the unmet medical need of those with HRS-AKI who have limited treatment options and are awaiting liver transplantation in the US.

    目的:在未治疗的HBV相关失代偿期肝硬化中,腹水和出血患者之间的再代偿是未知的。
    方法:在这项回顾性多中心研究中,首次发生腹水和/或静脉曲张破裂出血失代偿事件时,纳入初治HBV相关失代偿患者.进一步的并发症和临床特征收集使用标准病例报告表每6个月到5年的抗病毒治疗。再代偿被定义为在Child-PughA和/或MELD<10内保持无代偿一年并实现肝功能。
    结果:完全,腹水组298例(298例/383例,77.8%)初治失代偿患者170例(170例/298例,57.0%),出血组85例(85例/383例,22.2%)患者33例(33例/85例,38.8%),实现了补偿。腹水组5年复偿率高于出血组(63.3%vs.46.5%,p=0.012),分别。腹水组实现再补偿的患者第二次代偿率低于出血组(第5年:26.7%vs.43.3%,p=0.032)。具体来说,腹水组的再补偿患者主要有5年的进一步腹水率(24.0%)和更低的进一步出血率(6.0%),这与出血组的模式不同,进一步腹水的发生率较低(16.0%,p=0.599)和明显更高的进一步出血率(33.9%,p<0.001)。两名患者的长期预后均较好(第5年的死亡率/LT率:0.6%vs.3.0%,p=0.196)。
    结论:腹水患者通过抗病毒治疗可以获得比出血患者更高的再补偿率。在防止进一步出血方面,腹水组的再代偿患者预后较好。
    OBJECTIVE: Recompensation between patients with ascites and bleeding was unknown in treatment-naïve HBV-related decompensated cirrhosis.
    METHODS: In this retrospective multi-center study, treatment-naïve HBV-related decompensated patients were enrolled at first decompensating event of ascites and/or variceal bleeding. Further complications and clinical characteristics were collected using standard case report form every 6 months to year-5 of antiviral treatment. Recompensation was defined as maintaining free of decompensation for one year and achieving liver function within Child-Pugh A and/or MELD < 10.
    RESULTS: Totally, 170 (170/298, 57.0%) patients in ascites group of 298 (298/383, 77.8%) treatment-naïve decompensated patients and 33 (33/85, 38.8%) in bleeding group of 85 (85/383, 22.2%) patients, achieved recompensation. Ascites group had higher 5-year rate of recompensation than bleeding group (63.3% vs. 46.5%, p = 0.012), respectively. Patients achieving recompensation in ascites group maintained lower rate of second decompensation than these in bleeding group (at year-5: 26.7% vs. 43.3%, p = 0.032). Specifically, recompensated patients in ascites group had predominantly 5-year rate of further ascites (24.0%) and lower rate of further bleeding (6.0%), which differed from the pattern of these in bleeding group, with lower rate of further ascites (16.0%, p = 0.599) and significantly higher rate of further bleeding (33.9%, p < 0.001). Both patients had superior long-term prognosis (death/LT rate at year-5: 0.6% vs. 3.0%, p = 0.196).
    CONCLUSIONS: Ascites patients could achieve higher rate of recompensation through antiviral therapy than bleeding patients. Recompensated patients in ascites group had better prognosis in terms of preventing further bleeding.

    目的:最近的PREDICT研究表明,急性失代偿期(AD)肝硬化患者在入院后90天内可呈现三种不同的临床表型:(1)ACLF前,发展急性对慢性肝功能衰竭(ACLF);(2)不稳定的失代偿期肝硬化(UDC),没有ACLF的AD再次入院和(3)稳定的失代偿期肝硬化(SDC),不提出再接纳或ACLF。本研究旨在从外部验证这三个不同轨迹的存在,并确定每个轨迹发生的预测因素。
    方法:基线数据,在AD患者的前瞻性队列中分析了3个月ACLF和再入院发生率以及1年生存率。使用多项多变量模型来评估基线特征与临床轨迹之间的关联。
    结果:在入选的311名患者中,55%符合SDC的标准,UDC为18%,ACLF之前为27%,表现出明显不同的1年死亡率:ACLF前65%,UDC46%,SDC21%(p<.001)。肝性脑病(HE)的存在与UDC相关(p=0.043),而SDC没有腹水(p=0.017)。在实验室参数中,MELD-Na(p=.001)和C反应蛋白(p=.009)的升高以及血红蛋白(p=.004)和白蛋白(p=.008)的降低与ACLF前水平相关.
    结论:本研究证实AD患者有三种不同的临床轨迹和不同的死亡率。除了肝硬化的严重程度,与C反应蛋白的关联支持了全身性炎症在ACLF病理生理学中的主要作用.最后,HE与UDC表型相关,强调出院后需要更好地管理这种并发症。
    The PREDICT study recently showed that acutely decompensated (AD) patients with cirrhosis can present three different clinical phenotypes in the 90 days after admission: (1) pre-ACLF, developing acute-on-chronic liver failure (ACLF); (2) unstable decompensated cirrhosis (UDC), being re-admitted for AD without ACLF and (3) stable decompensated cirrhosis (SDC), not presenting readmission or ACLF. This study aimed to externally validate the existence of these three distinct trajectories and to identify predictors for the occurrence of each trajectory.
    Baseline data, 3-month ACLF and readmission incidence and 1-year survival were analysed in a prospective cohort of patients admitted for AD. A multinomial multivariable model was used to evaluate the association between baseline features and clinical trajectories.
    Of the 311 patients enrolled, 55% met the criteria for SDC, 18% for UDC and 27% for pre-ACLF, presenting a significantly different 1-year mortality: pre-ACLF 65%, UDC 46%, SDC 21% (p < .001). The presence of hepatic encephalopathy (HE) was associated with UDC (p = .043), while the absence of ascites to SDC (p = .017). Among laboratory parameters, an increase in MELD-Na (p = .001) and C-reactive protein (p = .009) and a decrease in haemoglobin (p = .004) and albumin (p = .008) levels were associated with pre-ACLF.
    The present study confirms that AD patients have three different clinical trajectories with different mortality rates. Besides the severity of cirrhosis, the association with C-reactive protein supports the predominant role of systemic inflammation in ACLF pathophysiology. Finally, HE is associated with the UDC phenotype highlighting the need for better management of this complication after discharge.

    目的:在回顾性病例对照研究中,采用XGBoost算法评估失代偿期肝硬化(DC)患者感染的有效预测因子。
    方法:回顾性收集5家三级医院收治的6,648例DC患者的临床资料。通过单变量分析和最小绝对收缩和选择算子(LASSO)回归确定具有显着差异的指标。进一步使用基于多树极端梯度增强(XGBoost)机器学习的模型对从LASSO中选择的特征的重要性进行排名,并随后使用简单树XGBoost模型构建感染风险预测模型。最后,将简单树XGBoost模型与传统逻辑回归(LR)模型进行了比较。通过受试者工作特征曲线下面积(AUROC)评估模型的性能,灵敏度,和特异性。
    结果:六个功能,包括总胆红素,血钠,白蛋白,凝血酶原活性,白细胞计数,选择中性粒细胞与淋巴细胞的比率作为DC患者感染的预测因子。通过这些特征进行的简单树XGBoost模型可以准确预测感染风险,训练集中的AUROC为0.971,灵敏度为0.915,特异性为0.900。简单树XGBoost模型在训练集上的性能优于传统LR模型,内部验证集,和外部特征集(P<0.001)。
    结论:基于医疗资源有限的DC患者可获得的最少量临床数据开发的简单树XGBoost预测模型可以帮助初级保健医生及时识别潜在的感染。
    OBJECTIVE: To appraise effective predictors for infection in patients with decompensated cirrhosis (DC) by using XGBoost algorithm in a retrospective case-control study.
    METHODS: Clinical data were retrospectively collected from 6,648 patients with DC admitted to five tertiary hospitals. Indicators with significant differences were determined by univariate analysis and least absolute contraction and selection operator (LASSO) regression. Further multi-tree extreme gradient boosting (XGBoost) machine learning-based model was used to rank importance of features selected from LASSO and subsequently constructed infection risk prediction model with simple-tree XGBoost model. Finally, the simple-tree XGBoost model is compared with the traditional logical regression (LR) model. Performances of models were evaluated by area under the receiver operating characteristic curve (AUROC), sensitivity, and specificity.
    RESULTS: Six features, including total bilirubin, blood sodium, albumin, prothrombin activity, white blood cell count, and neutrophils to lymphocytes ratio were selected as predictors for infection in patients with DC. Simple-tree XGBoost model conducted by these features can predict infection risk accurately with an AUROC of 0.971, sensitivity of 0.915, and specificity of 0.900 in training set. The performance of simple-tree XGBoost model is better than that of traditional LR model in training set, internal verification set, and external feature set (P < 0.001).
    CONCLUSIONS: The simple-tree XGBoost predictive model developed based on a minimal amount of clinical data available to DC patients with restricted medical resources could help primary healthcare practitioners promptly identify potential infection.

  • 文章类型: Multicenter Study
    目标:尽管韩国有治疗慢性丙型肝炎病毒(HCV)感染的直接抗病毒药物(DAA),仍然需要可以在存在肝功能损害的情况下使用的泛基因型方案,合并症,或先前治疗失败。我们调查了sofosbuvir-velpatasvir和sofosbuvir-velpatasvir-voxilaprevir在HCV感染的韩国成年人中12周的疗效和安全性。
    方法:这个阶段3b,多中心,开放标签研究包括2个队列.在队列1中,具有HCV基因型1或2的参与者,并且在基于干扰素的治疗中初治或有治疗经验的参与者,接受sofosbuvir-velpatasvir400/100mg/天。在队列2中,先前接受含NS5A抑制剂方案≥4周的HCV基因型1感染个体接受sofosbuvir-velpatasvir-voxilaprevir400/100/100mg/天。失代偿期肝硬化是一种排除标准。主要终点是SVR12,定义为治疗后12周HCVRNA<15IU/mL。
    结果:在接受sofosbuvir-velpatasvir的53名参与者中,52(98.1%)取得SVR12。未达到SVR12的单个参与者在第15天经历无症状的3级ASL/ALT升高并停止治疗。事件在没有干预的情况下解决。接受sofosbuvir-velpatasvir-voxilaprevir治疗的所有33名参与者(100%)均达到SVR12。总的来说,sofosbuvir-velpatasvir和sofosbuvir-velpatasvir-voxilaprevir是安全且耐受性良好的。队列1中的三名参与者(5.6%)和队列2中的一名参与者(3.0%)出现严重不良事件,但没有一个被认为与治疗相关。没有报告死亡或4级实验室异常。
    结论:在韩国HCV患者中,使用sofosbuvir-velpatasvir或sofosbuvir-velpatasvir-voxilaprevir治疗是安全的,并导致较高的SVR12发生率。
    Despite the availability of direct-acting antivirals (DAAs) for chronic hepatitis C virus (HCV) infection in Korea, need remains for pangenotypic regimens that can be used in the presence of hepatic impairment, comorbidities, or prior treatment failure. We investigated the efficacy and safety of sofosbuvir-velpatasvir and sofosbuvir-velpatasvir-voxilaprevir for 12 weeks in HCV-infected Korean adults.
    This Phase 3b, multicenter, open-label study included 2 cohorts. In Cohort 1, participants with HCV genotype 1 or 2 and who were treatment-naive or treatment-experienced with interferon-based treatments, received sofosbuvir-velpatasvir 400/100 mg/day. In Cohort 2, HCV genotype 1 infected individuals who previously received an NS5A inhibitor-containing regimen ≥ 4 weeks received sofosbuvir-velpatasvir-voxilaprevir 400/100/100 mg/day. Decompensated cirrhosis was an exclusion criterion. The primary endpoint was SVR12, defined as HCV RNA < 15 IU/mL 12 weeks following treatment.
    Of 53 participants receiving sofosbuvir-velpatasvir, 52 (98.1%) achieved SVR12. The single participant who did not achieve SVR12 experienced an asymptomatic Grade 3 ASL/ALT elevation on day 15 and discontinued treatment. The event resolved without intervention. All 33 participants (100%) treated with sofosbuvir-velpatasvir-voxilaprevir achieved SVR 12. Overall, sofosbuvir-velpatasvir and sofosbuvir-velpatasvir-voxilaprevir were safe and well tolerated. Three participants (5.6%) in Cohort 1 and 1 participant (3.0%) in Cohort 2 had serious adverse events, but none were considered treatment-related. No deaths or grade 4 laboratory abnormalities were reported.
    Treatment with sofosbuvir-velpatasvir or sofosbuvir-velpatasvir-voxilaprevir was safe and resulted in high SVR12 rates in Korean HCV patients.

    肝性脑病(HE)影响肝硬化患者的生存和生活质量。然而,缺乏HE住院后临床病程的纵向数据.目的是评估因HE住院的肝硬化患者的死亡率和再入院风险。
    我们在25个意大利转诊中心前瞻性招募了112例因HE住院的肝硬化患者(HE组)。一个队列的256名患者住院失代偿期肝硬化无HE作为对照组(无HE组)。他住院后,患者随访12个月直至死亡或肝移植(LT).
    随访期间,HE组34例(30.4%)死亡,15例(13.4%)行LT,在无HE组中,有60例患者(23.4%)死亡,50例患者(19.5%)接受了LT。在整个队列中,年龄(HR1.03,95%CI1.01-1.06),HE(HR1.67,95%CI1.08-2.56),腹水(HR2.56,95%CI1.55-4.23),和钠水平(HR0.94,95%CI0.90-0.99)是死亡的重要危险因素。在HE组中,腹水(HR5.07,95%CI1.39-18.49)和BMI(HR0.86,95%CI0.75-0.98)是死亡的危险因素,HE复发是再次住院的首要原因。
    因失代偿期肝硬化住院的患者,与其他失代偿事件相比,HE是死亡的独立危险因素,也是再次住院的最常见原因。因HE住院的患者应被评估为LT的候选人。
    UNASSIGNED: Hepatic encephalopathy (HE) affects the survival and quality of life of patients with cirrhosis. However, longitudinal data on the clinical course after hospitalization for HE are lacking. The aim was to estimate mortality and risk for hospital readmission of cirrhotic patients hospitalized for HE.
    UNASSIGNED: We prospectively enrolled 112 consecutive cirrhotic patients hospitalized for HE (HE group) at 25 Italian referral centers. A cohort of 256 patients hospitalized for decompensated cirrhosis without HE served as controls (no HE group). After hospitalization for HE, patients were followed-up for 12 months until death or liver transplant (LT).
    UNASSIGNED: During follow-up, 34 patients (30.4%) died and 15 patients (13.4%) underwent LT in the HE group, while 60 patients (23.4%) died and 50 patients (19.5%) underwent LT in the no HE group. In the whole cohort, age (HR 1.03, 95% CI 1.01-1.06), HE (HR 1.67, 95% CI 1.08-2.56), ascites (HR 2.56, 95% CI 1.55-4.23), and sodium levels (HR 0.94, 95% CI 0.90-0.99) were significant risk factors for mortality. In the HE group, ascites (HR 5.07, 95% CI 1.39-18.49) and BMI (HR 0.86, 95% CI 0.75-0.98) were risk factors for mortality, and HE recurrence was the first cause of hospital readmission.
    UNASSIGNED: In patients hospitalized for decompensated cirrhosis, HE is an independent risk factor for mortality and the most common cause of hospital readmission compared with other decompensation events. Patients hospitalized for HE should be evaluated as candidates for LT.
