Active clinical trials for "Acute-On-Chronic Liver Failure"

In this study, all patients with ACLF (Acute on Chronic Liver Failure) with grade III/IV HE (Hepatic Encephalopathy) getting admitted in our institute will be enrolled after the fulfilment of inclusion/exclusion criteria and consent of the patient's attendants. Investigation of the patient (as mentioned in the proforma) will be done. Intervention step 1: liq Lactulose 100 mL stat followed by 30 mL/ hourly through NG/NJ route + Lactulose enema 3rd hourly - till 4 time soft stool is passed, then 30 mL through enteral route 6th hourly (If patient has no bowel sounds, only enema will be given) Intervention step 2: (after 24 hours of introduction of step 1, if no rapid reduction in ammonia to <70mcg/dL) Randomization to L or R arm R Arm (Addition of Rifaximin) Continuation of Lactulose + addition of Rifaximin 400 mg 8th hourly through enteral route L Arm (Lactulose only) Continuation of Lactulose therapy for further 48 hours.

Point-of-care echocardiography (POC-Echo) is used to determine left ventricular systolic and diastolic dysfunction (LVDD), inferior vena cava (IVC) dynamics and volume status in cirrhosis and Acute-on-chronic liver failure ACLF accurately. We will assess IVC dynamics, LV systolic function [LV ejection fraction (EF) & cardiac output (CO)], and diastolic dysfunction (E/e', e' and E/A ratio) and urinary biomarkers (cystatin C and NGAL) in patients with cirrhosis and ACLF with hepatorenal syndrome-acute kidney injury (HRS-AKI).

Data for stool microbiome will be collected for all the chronic hepatitis B subjects (pre cirrhotic,compensated,decompensated and reactivation). All the in and out patient with Hepatitis B reactivation will be recruited and randomized into two arms. Group 1 Tenofovir Group 2 Tenofovir with FMT (Fecal Microbiota Transplant). Tenofovir would be given 300 mg once daily FMT through NJ (Naso-Jejunal) tube for 7 days.

Acute-on-chronic liver failure (ACLF) refers to a liver failure syndrome in which some patients with chronic liver disease with relatively stable liver function suffer from acute liver decompensation and liver failure due to the effects of various acute injury factors，while acute liver failure (ALF) refers to a potentially reversible disorder that was the result of severe liver injury, with an onset of encephalopathy within 8 weeks of symptom appearance and in the absence of pre-existing liver disease. Liver transplantation is the only curative treatment for this type of end-stage liver disease, but the rapid disease progression and lack of donors limit its application. The potential of MSCs to repair or regenerate damaged tissue and suppress immune responses makes them promising in the treatment of liver diseases, especially in the field of liver transplantation. Many studies have shown that MSC-based therapies can reduce the symptoms of liver disease due to their paracrine effects. It has been confirmed in previous studies that infusion of allogeneic MSCs is safe and convenient for patients with ACLF and improve liver function and decrease the incidence of severe infections. Compared to the cells they derive from, mesenchymal stem cells-derived extracellular vesicles (MSC-EVs) are gradually gaining attention for their enhanced safety, as they do not replicate or cause microvascular embolism, and can be easily stored without losing their properties. It represents a novel and effective cell-free therapeutic agent as alternative to cell-based therapies for liver diseases, and liver failure was also concerned. This study was designed to evaluate the safety and efficacy of MSC-EVs in ACLF/ALF .

To investigate the safety of Stemchymal® via intravenous (IV) infusion in acute liver failure (ALF) and acute on chronic liver failure (ACLF) patients.

Study design-Open label randomized controlled trial Study period-2 years Study population-All patients of ACLF admitted to ILBS for a period of two years from Feb 2017 to Dec 2018 All the patients of ACLF will receive standard medical therapy and will be randomized within 48 hours of admission into three groups after screening for exclusion and inclusion criteria.(1:2:2) Group A-Standard Medical Therapy only Group B-Standard Medical therapy + Plasma exchange + GCSF Group C-Standard Medical Therapy + GCSF

Hepatic encephalopathy is a frequent complication of both acute liver failure (ALF) and acute-on-chronic liver failure (ACLF) and could be responsible among other neurological complications of residual impairment after liver transplantation. Specific metabolomic studies have shed light into pathophysiology. Nevertheless, whether HE metabolomic fingerprints differ between HE in ALF and HE in ACLF and their evolution after liver transplantation (LT) is unknown. The aim of our study is to analyse the metabolomic fingerprint in plasma of 2 different groups of patients before and after LT: hospitalized patients with ALF and HE hospitalized patients with ACLF and HE We will analyse metabolomic results to explore if there is any difference in metabolomic fingerprints between these 2 groups and if LT modify the metabolomic fingerprint in plasma in these 2 groups and in the same way. We will collect blood samples in these 2 groups on the day of HE occurring and then on day 1, day 7 and day 30 (+/- 2 days) after LT. We aim to enroll 10 patients in ALF group and 20 patients in ACLF group. Inclusion criteria are defined as age > 18 years, patient presenting with ALF (Synthetic liver failure (INR > 1.5) with hepatic encephalopathy (grade 1-4 of West-Haven classification), without pre-existing hepatopathy, HE beginning within <26 weeks) or ACLF (≥ grade 1 from CANONIC criteria), and clinical HE (grade 1-4 of West-Haven classification) on the day of enrolment. Exclusion criteria are defined as age < 18 years, absence of HE, LT without pre-existing HE, patients who already undergone a LT, legally protected person. An EDTA blood sample will be collected, centrifuged and frozen on the day of enrolment, then on day 1, day 7 and day 30 (+/- 2 days) after LT. Metabolomic analyses will be performed by different techniques but especially with high resolution liquid phase mass spectrometry in collaboration with CEA. Statistical analyses will be both univariate (Mann-Whitney or Wilcoxon tests) and multivariate (with a classical and adapted method for metabolomic studies: Partial Least-Squares Discriminant Analysis (PLS-DA)). We expect to identify different metabolomic fingerprints between HE in both ALF and ACLF patients as well as different kinetics for symptoms resolution after LT. The long-term objective is to target the specific metabolic pathways for each group in order to allow development of new targeted drugs against HE in these 2 different conditions.

Acute-on-chronic liver failure (ACLF) refers to the acute deterioration of liver function in patients with chronic liver disease. Neutrophils are a major component of the innate immune system, and previous studies have revealed enhanced production of neutrophil extracellular traps (NETs) in ACLF. However, there is still a lack of systematic research on the correlation between NETs and the prognosis of ACLF. We screened NETs related biomarkers through bioinformatics analysis, which play an important role in the diagnosis of ACLF. This study will explore whether these NETs related biomarkers also play an important role in the prognosis of ACLF and further investigate their role in the pathogenesis of ACLF.

CPFA is currently used in the treatment of severe sepsis with the intention of removing the proinflammatory mediators from the systemic circulation. Some evidence exists about the bilirubin adsorbing ability of the neutral styrenic resin which is part of the extracorporeal circuit of CPFA. The aim of this study is to assess efficacy and safety of CPFA in extracorporeal detoxification of liver toxins in patients affected by acute or acute-on-chronic liver failure.
