Filter by:The AIM of the study is to study the efficacy of intravenous albumin and standard medical treatment as compared to standard medical treatment alone in ameliorating/preventing SIRS and improving survival at 28 days .The project will be conducted in ILBS from august 2018 to December 2019Concept is to understand the immunology, pathophysiology and effects of albumin in the management of ACLF for betterment of the patient's condition and early recovery. All ACLF patients will be included as per the inclusion and exclusion criteria , after taking informed consent from the patient or their relatives. Will be evaluated for the possible risk factors for the development of SIRS/sepsis in ACLF patients and possible beneficial factors for resolution of SIRS /sepsis in ACLF patients. The effects of albumin administration as per this protocol versus standard medical treatment alone will be reviewed If patient develops allergic reactions to albumin, fluid overload, albumin will be stopped and patient will be treated accordingly to medical condition.
This is a Phase 3, multicenter, randomized, controlled, parallel-group, open-label study to evaluate the effects of plasma exchange using human serum albumin 5% (PE-A 5%) in acute-on-chronic liver failure (ACLF) subjects. The study will involve approximately 40 study centers in the United States, Canada, and Europe with expertise in the management of subjects with ACLF. Subjects with ACLF at a high risk of hospital mortality will be enrolled. The study will consist of a Screening Period during which subjects will be randomized (1:1) to receive either standard medical treatment (SMT) + PE-A 5% (treatment group) or SMT only (control group), followed by a Treatment Period, and a Follow-up Period. The Treatment Period for subjects in the SMT+ PE-A 5% treatment group will be between 7 and 17 days, depending on ACLF evolution. The Treatment Period for subjects in the SMT control group will be a minimum of 7 days for all subjects and up to 17 days depending on the ACLF evolution. Subjects in this group will receive SMT according to the institution's standards. The Follow-up Period for subjects in both groups will be 90 days.
HBV-related acute-on-chronic liver failure (ACLF) is a clinical syndrome defined as acute hepatic insult with diagnosed or undiagnosed chronic liver disease. Current clinical guidelines advocate oral antiviral treatment in HBV-related ACLF. However, no conclusion on which nucleoside analogue is the most satisfactory drug for the treatment of HBV-related liver failure has not been reached yet. In this cohort study, the investigators will compare the efficacy, safety, and tolerability of tenofovir alafenamide (TAF), Tenofovir Disoproxil Fumarate (TDF) and entecavir (ETV) in HBV-related ACLF in China. In addition, the drug metabolism characteristics of TAF will be explored in such severe liver injury population of HBV-ACLF.
Hepatectomy is an essential treatment for various benign and malignant diseases of the liver. However, post-hepatectomy liver failure (PHLF) is still a life-threatening complication after hepatectomy. The pathophysiological mechanism of PHLF has not yet been fully elucidated, and there is still a lack of effective strategies for either prevention or therapy of PHLF. Sphingolipids include ceramides (CER), sphingomyelins (SM), glycosphingolipids (GSL), sphingosine (SPH), and sphingosine-1-phosphate (S1P) are multi-functional lipids that regulates cell proliferation, cell survival, cell death, inflammation, tissue fibrosis, cancer cell metastasis, and invasion. Liver is a main organ for metabolizing sphingolipids, dysregulation of specific sphingolipids is associated with several liver diseases, therefore sphingolipids have been proposed to be biomarkers of liver diseases, including hepatitis, liver cancer, fatty liver diseases, and liver fibrosis. Moreover, several studies have shown CER, SPH and S1P are critical in regulating pathophysiology of liver diseases, including liver regeneration, necrosis, and inflammation. Given that PHLF causes dramatic dysregulation in biochemical metabolism in liver, the investigators hypothesize that dysregulation of sphingolipid metabolism may also occur in PHLF, and the dysregulation of specific sphingolipids may serve as a biomarker or regulator during progression and recovery of PHLF. This project will examine the association between sphingolipid metabolism and PHLF. Levels of sphingolipid metabolites and their related enzymes in plasma and liver tissue of patients with hepatic resection will be measured by using liquid chromatograph/electrospray ionization/mass spectrometry (LC-ESI-MS/MS) and high-throughput real-time quantitative PCR. This project will facilitate us to identify specific sphingolipid metabolites as biomarker and regulator of PHLF.
The aim of this study is to validate and develop a new diagnostic and prognostic approach for assessment of liver function in children and adolescents with acute liver failure and chronic liver insufficiency. A carefully selected panel of functional and genomic tests along with diagnostic imaging and analysis of the microbiota will be performed in children and adolescents with acute liver failure and chronic liver insufficiency at Rigshospitalet. The tests will be performed in a serial manner in order to detect changes in outcomes. The study is an unblinded descriptive study, and approximately 20 patients with acute liver failure and 100 patients with chronic liver disease will be included in the project. This study will be the first of it's kind worldwide. The investigators expect the study to improve future diagnostic and prognostic accuracy and help the clinicians in identifying those patients in which the liver will regenerate itself, from those patients in which a liver transplantation will be lifesaving. Furthermore this study aims to help the clinicians in defining the optimal time for pediatric liver transplant in a narrow window of opportunity.
Extended hepatectomies of 4 or more segments are complicated by high rates of morbidity and mortality, mainly related to hepatic liver failure. Nowadays, preoperative assessment of the future remnant liver is just performed through its volumetric measurement by computed tomography. Nevertheless, this volumetric assessment does not reflect the hepatocellular function of the future remnant liver that can be disturbed in case of vascular and/or biliary obstruction, chemotherapy-induced liver injuries or steatosis in overweight patients. Literature data (albeit originating from a single centre in Europe) have suggested that (99m)Tc-mebrofenin hepatobiliary scintigraphy could be useful in evaluating the function of the future remnant liver. The aim of this prospective multicentric study is to determine the predictive value of hepatobiliary scintigraphy in assessing the risk of postoperative liver failure of extended hepatectomies of 4 or more segments in noncirrhotic liver.
This ring aimed to preserve an intra-hepatic porto-caval gradient inferior to 5 mm Hg during and after major hepatectomy (48h) to protect the liver during the initial phases of liver regeneration. Morphological features of MID-AVRTM allow its intra corporeal opening and percutaneously removal after an balloon inflation with 5 ml of physiological serum. MID-AVRTM had been developed in pig where it had proved its efficiency to improve liver function after 75% hepatectomy and its capacity to be removed percutaneously. Aim of this feasibility study (Phase I/II) is to prove in series of 3 evaluable patients (Phase A) then 6 evaluable patients (Phase B) that MID-AVRTM could be used in human without deleterious consequence. In phase A, MID-AVRTM is dispose around the portal vein before and during a major hepatectomy performed on healthy liver and removed before abdominal closure. If phase A results confirmed that MID-AVRTM well modulates portal pressure and is easily opened and removed by acute inflation, the phase B will be started. In phase B, MID-AVRTM will be dispose around the portal vein before major hepatectomy on healthy liver and conserved 48 hours before to be removed percutaneously at the operating room.
The purpose of this study is to determine whether Icotinib is efficient and safe in treating advanced non-small cell lung cancer (NSCLC) patients with hepatic insufficiency.
The cerebrovascular autoregulation (AR) is impaired in patients with hepatic encephalopathy. Patients with the indication to liver transplantation mostly have mild to severe hepatic encephalopathy. Transplantation should recover the encephalopathy. The aim of the study is to investigate the AR during liver transplantation, with the questions if the AR is impaired at the beginning of surgery and if there are changes in AR. For follow up the AR will be measured at the first days after transplantation at the ICU.
This clinical investigation of the hepatocyte matrix implant is an evaluation blinded non-randomized and monocentric pilot study of Phase I, which is conducted as a therapeutic investigation. Randomization is not possible due to ethical and practical reasons. This study has already been approved in Switzerland and has been adapted to Indonesian Law and disease. This new treatment procedure has already been successfully used on the basis of compassionate use in Germany. The hepatocyte matrix implant is a new patented procedure consisting of bio-matrix technology. A formaldehyde-free special matrix consisting of self-dissolving polymers is applied as a carrier substance and is cultivated with human autologous cells using a special technique. Clinically the bio artificial liver replacement tissue for patients with end-stage hepatic disease has been developed as a first application. In this procedure autologous hepatocytic tissue and pancreatic tissue is removed (liver resection and pancreatic biopsy) from the patient in a first surgical procedure. The tissue is sent to a specialized Cell Culture Laboratory. The laboratory is GMP certified for this procedure. The cells are processed according to SOPs in a special perfusion procedure and prepared on several platelets of matrices (platelets of 20 mm diameter and 4mm thickness). After completion of the laboratory process the bio tissues are implanted into the mesentery of the small intestine during a second operation. The cells are growing controlled on the matrix, take on the capillaries of the patient and thus connect to the blood circulation. The implanted cells multiply by a specific factor and independently take over the metabolic function of the original liver after two to four weeks. In the following process the carrier matrix dissolves completely and implanted cells develop into liver cell tissue.
