Neuromonitoring of critically ill patients in the intensive care unit (ICU) is challenging. Clinical scoring systems produce insufficient information with deeply sedated patients, and disturbances of normal hemostasis limit the use of invasive intra-cranial pressure measurements. EEG based monitoring algorithms have been introduced into the operation theater and general anaesthesia, but these algorithms cannot be used in the intensive care setting without modifications. EEG is also susceptible to electrical disturbances, such as those created by patient movement. The study is conducted in Finland, in the intensive care unit of the Surgical Hospital of Helsinki. The total number of patients in this study is 20, and it is a part of a larger neuromonitoring study with a total of 110 patients. The patients are divided into four subgroups, as follows: 1. patients admitted to ICU with acute liver failure, 2. patients admitted to the postoperative cardio-thoracic ICU after cardiac surgery with perioperative total heart arrest, 3. patients admitted to the ICU because of status epilepticus and finally 4. patients in critical condition, admitted to the ICU after any surgery. This study concentrates on the first group of patients with acute liver failure. Clinical care of patients is not altered. When arriving into the ICU EEG-monitoring will added to routine monitoring. To evaluate the neurological status the following tests are performed: clinical test, blood tests and transcranial doppler ultrasound. The Entropy of EEG is measured along with the raw EEG signal. The recruiting of study patients was begun in December 2005 and the final study patients were recruited in December 2011. GE Healthcare Finland supplies the entropy monitoring devices and pays the salary of the research nurses who collect the study data. Clinical investigators will not receive funding from any commercial company. All patients (or their next of kin) included have given their written informed consent for inclusion in the study. The aim of this study is to find new factors and new non-invasive techniques, which correlate with the neurological state and outcome of patients suffering critical illness.
This phase 2 study is developed to evaluate the effect of ELAD on overall survival (OS) in subjects with acute liver failure (ALF) compared to matched historical controls.
After successful screening diagnosis of cirrhosis and/or acute or chronic liver failure will be made. These patients will undergo detail clinical, biochemical and microbiological examination at baseline. Clinical examination and Biochemical evaluation will be done daily and signs of infection will be noted. Patients will undergo microbiological screening for infection every 48 hours. Patients suspected or diagnosed to be suffering from infections will be treated as per ILBS (Institute of Liver and Biliary Sciences) antibiotic policy. Site and etiology (bacterial and/or fungal) of infections will be noted in all patients at admission in liver specialty ICU (Intensive Care Unit) and during the ICU (Intensive Care Unit) stay. All the patients will be followed until discharge or death in ICU (Intensive Care Unit).
Transient elastography is novel non-invasive method for assessment of hepatic fibrosis in patients with chronic liver disease, by measuring liver stiffness. Transient elastography is a user friendly technique that can be easily performed at bedside or in outpatient clinic with immediate results and good reproducibility. Liver stiffness values ranges from 2.5 to 75 kPa with lower values <6kPa suggest no fibrosis where as higher values above 14kPa suggests cirrhosis. In the present study the investigators hypothesis that the investigators can differentiate ACLF and acute severe viral hepatitis based on fibroscan as patients with underlying fibrosis with superadded inflammation would have higher fibroscan value than when patient have only inflammation with no underlying fibrosis and hence the investigators can avoid unnecessary test in such subgroup.
Pharmacokinetics of Buprenorphine and Naloxone in Subjects with Mild to Severe Hepatic Impairment and in HCV-Seropositive Subjects, and in Healthy Volunteers.
HBV-related liver failure (HBV-LF), a dramatic clinical syndrome, is characterized with massive necrosis of liver cells. Liver transplantation might be the most effective therapy for HBV-LF. However, there are a lot of problems such as lack of donors, surgical complications, transplant rejection, and high cost, which could limit the application of liver transplantation. It is demonstrated that mesenchymal stem cells could directionally differentiate into hepatocytes and cholangiocytes in injured liver, as well as reduce inflammation of the liver by immune regulation. In this study, we assess the safety and efficacy of human bone marrow and umbilical cord mesenchymal stem cells transplantation for patients with HBV-LF.
This study was to predict 3-month mortality risk of acute-on-chronic hepatitis B liver failure (ACHBLF) on an individual patient level using artificial neural network (ANN) system. The area under the curve of receiver operating characteristic (AUROC) were calculated for ANN and MELD-based scoring systems to evaluate the performances of the ANN prediction.
The purpose of this study is to investigate safety and efficacy of intravenously injected 0.4% 13-C-Methacetin solution for the determination of liver function with the LiMAx-test on patients with partial liver resection. The LiMAx-test is compared with an untreated control group and post-surgical management of both groups is investigated.
It is a cohort to evaluate the power of different diagnostic tests in predicting the prognosis of patients with severe liver disease. Patients with decompensated liver cirrhosis on the waiting list for liver transplantation will be evaluated with comparison of different diagnostic tests according to the MELD score (Model for End-Stage Liver Disease), MELD-Na (Model for End-Stage Liver Disease and sodium), indocyanine green clearance test, hepatic venous pressure gradient and transient elastography. All patients will be submitted to all the tests and prospectively followed for 6 months, to establish mortality and complications related to liver disease in order to define the value of each method to predict outcomes.
