Filter by:Tenofovir alafenamide (TAF) and entecavir (ETV) are the preferred agents in patients with predisposing factors for nephrotoxicity, but few studies to date have directly compared the renal safety of the two antiviral drugs in patients with acute-on-chronic liver failure (ACLF). Hence, the investigators compared the risk of kidney function decline among patients with HBV related acute-on-chronic liver failure (HBV-ACLF) treated with ETV or TAF.From April 2020 to June 2021, a total of 272 HBV-related ACLF hospitalized patients in the Xiangya Hospital of Central South University were enrolled in this prospective study. Chronic hepatitis B was diagnosed by hepatitis B surface antigen and/or hepatitis B virus deoxyribonucleic acid (HBV-DNA) positivity for ≥6 months. ACLF was diagnosed based on the criteria proposed by the APASL Working Party. All patients received antiviral therapy with TAF (25 mg QD, n=100) or ETV (0.5mg QD, n=172), and comprehensive medical treatments. Clinical and laboratory data were collected to evaluate the progression of chronic kidney disease (CKD) .
Monitoring and Assessment: Transient Elastography will be performed in morning hours using the FibroScan apparatus (Echosens), which consists of a 5-MHz ultrasound transducer probe mounted on the axis of a vibrator. The tip of the transducer (M-or XL probe) will be covered with a drop of gel and placed perpendicularly in the intercostal space, with the patient lying in dorsal decubitus position with the right arm in the maximal abduction. Under control, in time motion and in A-mode, the operator will choose a liver portion within the right liver lobe, at least 6-cm thick and free of large vascular structures, and the gallbladder. Liver stiffness (LS) will be measured on a cylinder of hepatic tissue of 1 cm of diameter and 4 cm of length. For assessing the splenic stiffness (SS), the patient will be in supine position with left arm in maximum abduction. Ultrasonography will be used to identify and locate the spleen parenchyma, to choose the right place for SS measurement, and to measure the spleen diameter (long axis). Transducer will be placed in the left intercostal spaces, with location indicated by the ultrasound. A median value of 10 successful acquisitions, expressed in kPa, will be kept as a representative of the LS and SS measurements. The LS and SS measurement failure will be recorded when no value will be obtained after at least 10 shots. The results will be considered unreliable in the following circumstances: valid shots fewer than 10, success rate < 60%, or interquartile range / LS >30 %. Liver and splenic stiffness, LSPS score (LS measurement × spleen diameter / platelet count), Platelet count to spleen diameter ratio (PSR) will be calculated. Patient will also undergo upper g.i. endoscopy on same day. HVPG and TJLB will be done if indicated. The study will assess whether the stiffness scores correlate with presence of esophageal varices. Optimum cutoffs will be calculated for predicting the presence of esophageal varices. - Study design: A Cross-Sectional Study - Study period: 12 months - Sample size with justification: Consecutive Patients of ACLF from approval of study to 12 months. ACLF patients will be screened and eligible patients will be taken in to the study. - Intervention: Patients of ACLF will undergo upper g.i. endoscopy, liver and splenic stiffness measurement. HVPG and TJLB will be done in the patients only if clinically indicated.
Citrate has been proposed as anticoagulation of choice in continuous renal replacement therapy (CRRT). However, little is known about the pharmacokinetics (PKs) and metabolism of citrate in liver failure patients who require CRRT with regional citrate anticoagulation (RCA).
Cirrhosis is a condition characterized by diffuse fibrosis, severe disruption of the intrahepatic arterial and venous flow, portal hypertension and, ultimately, liver cell failure. Traditionally, cirrhosis has been dichotomised in compensated and decompensated, and the transition to decompensated cirrhosis happens when any of the following hallmarks occurs: presence of ascites, variceal haemorrhage and/ or hepatic encephalopathy (HE) . In Egypt, HCV is the main cause of liver cirrhosis followed by HBV
Acute on chronic liver failure (ACLF) is a distinct entity where, because of severe acute hepatic injury, a rapid loss of liver function develops in a patient with previous chronic liver disease(4). These patients have severe hepatic dysfunction, and outcome is defined by functional hepatic reserve and extent of extra-hepatic organ failures(5). Renal failure is a frequent extra-hepatic organ failure, and its presence is an independent prognostic marker for mortality(12). The pathophysiological basis of renal dysfunction in patients with ACLF is different compared to those with decompensated cirrhosis (DC)(6). Systemic inflammation is the hallmark of ACLF, characterized by a cytokine storm wherein there is an increase in both pro- and anti-inflammatory cytokines, such as interleukin (IL)-6, IL-8, IL-1β, and IL-10, leading to circulatory dysfunction and organ failure(3). These patients therefore have a higher incidence and progression of acute kidney injury (AKI). Diagnosis of HRS-AKI in ACLF currently requires 48 h of volume repletion with albumin and diuretic withdrawal. Therefore waiting for 48 hours to start treatment with terlipressin can be associated with worsening of AKI stage, worsening of ACLF stage and thereby suboptimal treatment response and high mortality despite treatment response. Therefore early initiation of terlipressin as continuous infusion after volume repletion with IV albumin in ACLF-AKI is safe and prevents AKI progression by splanchnic vasoconstriction and improved renal perfusion.
Bowel colonization with anti-microbial resistant bacteria increases the risk of clinical infections. Infections caused by anti-microbial resistant bacteria have been associated with increased mortality, prolonged hospital stay, and increased costs. In addition, with the emergence of carbapenemase resistant bacterial species, there may not be any effective therapy for patients infected with such resistant species. Bowel colonization with anti-microbial resistant bacteria is an established risk factor for infections due to resistant bacteria, especially in transplanted patients and in intensive care unit. In this study we will study whether bowel colonisation in Acute on Chronic Liver Failure patient increases the risk of infection development in extra intestinal sites.
Background: Patients with cirrhosis and acute-on-chronic liver failure (ACLF) may have bleeding complications which can lead to increased mortality. Standard coagulation tests (SCTs) like prothrombin time, platelet count and activated partial thromboplastin do not accurately depict in vivo coagulation profile. Point-of-care viscoelastic coagulation testing devices like thrombo-elastography (TEG) and Sonoclot may be better for guiding patient management. Methods: This prospective observational study compared and validated the point of care (POC) tests and SCTs in 70, 72 and 25 persons with ACLF, decompensated cirrhosis and healthy controls respectively.
This study analyses the effect of intravenous branched chain amino acids (BCAA) on overt HE in patients with ACLF. The investigators plan to study the efficacy of combining intravenous BCAA with lactulose versus lactulose alone in the medical management of overt HE in patients with ACLF and its impact on overall survival and improvement in grade of HE.
Ineffective hemostasis or a paradoxical prothrombotic state of Acute-on-chronic liver disease (ACLF) has been well established. Thrombelastography measures the dynamics of thrombin production and provides a global assessment of coagulation incorporating the cumulative effect of the interactions at various levels between plasma components and cellular component of coagulation. And through the platelet mapping, it can help provide a picture of patients' function of platelet. Based on the primary result of our derivation cohort(NCT03281278), ACLF patients with high ADP inhibition rate had high 28-day mortality.This multicenter validation cohort aims to validate the predictive role of platelet mapping in ACLF prognosis, organ failure developments and short term mortality.
Acute-on-chronic liver failure (ACLF) is an acute deterioration of chronic liver diseases, which progresses rapidly, with a mortality rate of more than 50%.MELD score is used to evaluate the patients' condition. However, MELD score only concerned about the variables of total bilirubin, international normalize ratio (INR) and creatinine which is not enough to access ACLF patients' condition accurately. Scholars of US and China suggested to divided ACLF patients into 3 subgroups base on the different "chronic liver disease" . Type A ACLF patients have chronic liver disease without cirrhosis. Type B ACLF patients with compensated cirrhosis, while type C ACLF patients with decompensated cirrhosis. Currently, no studies have assessed the prognosis of different types of ACLF patients, especially for HBV-related ACLF patients. Investigators conducted a retrospective study which enrolls HBV-related ACLF patients between January 2010 and March 2018 in the Third Affiliated Hospital of Sun Yat-sen University. Clinical data, survival time and information regarding liver transplantation after enrolment were collected. A nomogram was formulated based on the results of multivariable Cox regression analysis. The performance of the nomogram was evaluated by the concordance index (C-index) and assessed by comparing nomogram-predicted vs observed Kaplan-Meier estimates of survival probability, and bootstraps with 1000 resamples were applied to these activities. Comparisons between the nomogram, MELD Score，MELD-Na Score and CTP Score in the entire population were performed and were tested by the C-index. A larger C-index indicated more accurate prognostic stratification.
