Plasma Free Amino Acids in Patients With Hepatic Encephalopathy

Hepatic Encephalopathy

This is study to investigate the plasma free amino acids profile in patients with decompensated liver cirrhosis and hepatic encephalopathy and its relation to the nutritional state of these patients. To investigate the plasma free amino acids relation to the nutritional state of patients with liver cirrhosis and hepatic encephalopathy. To determine the effectiveness, cost, cost-benefit and in-hospital prognosis of branched chain amino acid (BCAA) infusion as an adjuvant to conventional mainstay therapy in the treatment of hepatic encephalopathy due to liver cirrhosis. To determine the effectiveness of branched chain amino acid (BCAA) infusion on improving amino acid imbalance and Fischer ratio (Branched chain amino acids/Aromatic amino acids ratio).

Role of MRI in Detection of Minimal Hepatic Encephalopathy

Liver CirrhosesHepatic Encephalopathy

Introduction Liver cirrhosis (LC) is irreversible fibrosis of the liver (1) and it remains a public health problem. One of the complications of the cirrhosis is hepatic encephalopathy (HE) which is defined as brain dysfunction caused by liver insufficiency. Pathophysiological mechanisms of HE are complex and multifactorial. Recognition of beginning stages of HE, such as minimal HE (mHE) is of most importance. Objectives and originality of the project Diagnosis of mHE can be challenging, time-consuming and, at least to some extent, subjective. This project will assess the role of magnetic resonance (MR) in mHE diagnosis with emphasis on multimodal imaging technique. With advanced magnetic resonance (MR) techniques, in-vivo detection of intracellular water content, estimation pH and metabolites levels with millimolar concentrations can be easily performed. This will offer to explore possible pathophysiological mechanisms of HE and to evaluate the results from previous, studies that were mainly performed on animal models or cell cultures. By our best knowledge, multimodal MR approach as the investigators propose in this application has not been yet performed. The investigators will use advanced MR techniques which are currently not available in the clinical setting and require multicenter collaboration. Methods The investigators will include 10-20 patients of both genders with hyperammonemia and mHE and 10-20 patients of both genders with HE. Diagnosis of HE will be made based on results of validated neuropsychiatric test. Age-matched and gender-matched control group with no gastrointestinal, neurological or psychiatric complaints and normal levels of ammonia in the blood. Patients with mHE/HE will be included from outpatient clinic of the Department of gastroenterology, University Medical Centre (UMC) Ljubljana. Healthy controls (HC) will be invited to join via internet advertisement. Contraindications for HC will include gastrointestinal (emphasis on liver disease), neurological or psychiatric complaints. Grade of mHE/HE will be classified according to West-Haven (WH) classification. Patients with different degree of liver cirrhosis, which will be scored with the Child-Pugh (CP) score, and with no contraindications for MR (e.g. presence of metal in body) will be included. Blood levels of liver enzymes and ammonia will be measured in all participants. MR scanning will include: T1- and T2-weighted MR, MRS (MEGA-PRESS and PRESS) in two voxels: striatum and cerebellum. Location will be double-checked by voxel position screenshots. Analysis, with voxel-positioning error compensation will be performed in Gannet (www.gabamrs.com). Moreover, high resolution diffusion weighted imaging (DWI), diffusion kurtosis imaging (DKI), quantitative susceptibility mapping (QSM) will be performed in brain as well. Liver QSM will be executed to assess iron load.

Timing of Acute Palliative Care Consultation in Critically Ill Patients

Multiple Organ FailureEnd Stage Cardiac Failure9 more

A prospective randomized controlled trial studying the ordering of palliative care consultations in the emergency department (Ig) versus later palliative care consultations in the hospital--ICU or hospital ward(Cg). Patients will be randomly allocated to Ig or Cg with a 1:1 ratio.

The International Imaging Registry in Liver Cirrhosis (BAVENO-VI SPSS GROUP).

Liver CirrhosisPortal Hypertension1 more

The purpose of this study is to perform a multicentre registry of cirrhotic patients who had been submitted to an imagining technique in recent years (angio-CT scan or abdominal MRI), in order to collect anatomical and clinical information. The main objective will be focused on the study of portosystemic shunts and their relation with portal hypertension. Patient with liver cirrhosis submitted to an abdominal angio-CT scan or a MRI from year 2010 to 2014 will be included in the study. The chosen imaging technique will be angio-CT preferably, but MRI data will also be available. Patients will be identified in every hospital by means of the registry of coded diagnoses and the lists of complementary tests performed. Clinical and radiological data of every patient will be collected. The clinical variables will be obtained from reviewing the patient clinical history. The radiological parameters will be gathered by means of the systematic review of the angio-CT or MRI.

Prediction of Mortality in Patients Waiting for Liver Transplantation Through Brain Magnetic Resonance...

End Stage Liver DiseaseHepatic Encephalopathy

The purpose of this study is to determine whether hepatic encephalopathy, measured through magnetic resonance imaging, electroencephalogram and neuropsychological evaluation adds prognostic information to patients who are waiting for liver transplantation. If this model improves mortality prediction this might be used in the future for organ allocation.

Cerebrovascular Autoregulation During and After Liver Transplantation

EncephalopathyHepatic2 more

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.

Quantitative Determination of Brain Water Content in Patients During and After Hepatic Encepalopathy...

Hepatic Encephalopathy

There is increasing evidence that the pathophysiology of hepatic encephalopathy (HE) is tightly associated with low-grade cerebral edema. Uptake of ammonia in astrocytes leads to osmotic swelling caused by glutamine formation. Previous studies were performed in covert HE patients or used indirect methods. Methods: The investigators wish to describes quantitative measurement of localized water content using MRI water mapping in a cohort of patients with cirrhosis during an episode of overt HE type C and again after recovery. Furthermore patients with cirrhosis and no history of HE and healthy subjects will be investigated as controls.
