Parenteral Nutrition Associated Liver DiseaseEssential Fatty Acid Deficiency3 moreThis study will demonstrate Short-, mid-, and long-term safety in pediatric patients with Parenteral Nutrition-Associated Cholestasis treated with Omegaven®, which is indicated as a source of calories and fatty acids in this patient population
A Study of LY3314814 in Participants With Liver Impairment
Hepatic ImpairmentThe purpose of the study is to determine whether LY3314814 can be safely prescribed in participants with liver impairment without a dose adjustment. Participants will be on study for 11 days with follow-up about 7 days afterward.
FDGal PET/CT to Detect Hepatocellular Carcinoma
Hepatocellular CarcinomaLiver Cirrhosis1 moreLiver cancer is one of the leading causes of cancer death among Asian men. If diagnosed early the disease is treatable with surgery. Current conventional imaging modalities have limitations to early detection. This study proposes to use 18F-FGal and 18F-FDG PET/CT scans to compare the clinical efficacy of diagnosing hepatocellular carcinoma (a type of liver cancer) using these PET/CT scans.
Longitudinal Outcomes in Hepatic Resection
Liver DiseasesSurgeryThis observational registry of patients undergoing liver surgery collects patients both retrospectively and prospectively. Patients undergoing liver resection for any non-transplant indication will be evaluated for clinical outcomes (such as surgical complications, survival, and disease progression) based on clinical and patient factors (like indication, age, and other treatments for the disease).
Cellular Immune Responses in the Liver in Chronic Hepatitis C (CHC) Patients
Hepatitis CChronic2 moreIn order to persist in the liver, HCV has numerous nonspecific and specific strategies to overcome the immunity of the host. The crucial step in the establishment of viral persistence and chronic hepatitis is the avoidance of specific antiviral cellular immune response in the liver. Treatment with pegylated interferon alpha (IFNα) in combination with ribavirin (RBV) is the standard therapy for chronic hepatitis C is. The response to IFNα / RBV therapy depends on the effective cellular antiviral immune response in the liver. The understanding of the interaction between HCV and cellular immune response is important for the effective use of existing diagnostic techniques, the Individual control and adjustment of the current therapeutic approaches and the development of future therapeutic and immunization strategies. In this study, the investigators want to investigate cellular Immune responses in the liver of HCV infected patients and characterize the influence of these immune responses to the response to IFNα / RBV therapy.
A Study to Evaluate Vaccines Against COVID-19 in the Real World
Chronic Liver DiseaseHepatic CarcinomaSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and the resulting coronavirus disease 2019 (COVID-19) have afflicted tens of millions of people in a worldwide pandemic. Considering its high mortality and rapid spread, an effective vaccine is urgently needed to control this pandemic. Recently, mass vaccination campaigns using newly approved vaccines, ranging from conventional viral and protein-based vaccines to those that are more cutting edge, including DNA- and mRNA-based vaccines are beginning in many parts of the world. Randomized clinical trials of different vaccines reported efficacies for preventing COVID-19 in the range of 50% to 95%. Although these randomized clinical trials are considered the "gold standard" for evaluating intervention effects, they have notable limitations of sample size and subgroup analysis, restrictive inclusion criteria, and a highly controlled setting that may not be replicated in a mass vaccine rollout. The aim of this study is to evaluate the safety, tolerability, immunogenicity, and efficacy of different vaccines against COVID-19 under real-world practice conditions.
Natural History of Non Alcoholic Fatty Liver Disease and Predictors of Advanced Fibrosis
Non-alcoholic Steatohepatitis (NASH)The prevalence of non-alcoholic fatty liver disease (NAFLD ) in the American population is approximately 30% in adults and 10% in children, making it the most common. Cause of chronic liver disease in the United States. Although the majority of patients with NAFLD have a benign clinical course, the development of non-alcoholic steatohepatitis (NASH ), with necro-inflammation and progressive fibrosis, increases the risk for development of cirrhosis and its complications. Among patients with NASH, approximately 28% develop cirrhosis over an 8-year follow-up period. NASH and advanced fibrosis is associated with increased morbidity and mortality among those patients with advanced histologic severity such as NASH and fibrosis the gold standard for diagnosing and staging NAFLD is liver biopsy. Liver biopsy is associated with costs and risks that make it impractical for generalized use in a condition that affects such a high portion of the population. Furthermore, liver biopsy is also limited by significant sampling error in NAFLD. Thus, there is a pressing need for accurate non-invasive predictors of NAFLD that would also allow differentiation of those subjects at higher risk of disease progression. At present, in the clinical setting, some demographic factors, blood tests, and imaging studies can be used to predict a higher risk of disease in patients being evaluated for NAFLD. These predictors, however, are of limited sensitivity and specificity compared with liver biopsy. The development and validation of accurate predictors and scoring systems to identify patients at higher risk for NASH and fibrosis would allow identification of subjects who would benefit the most from liver biopsy and potentially help monitor disease
Surgical Treatment of Hydatid Liver Disease
Hydatid CystHepaticThe goal of this observational study is to show that cyst extraction with pericyst reduction and omentopexy is a suitable treatment for liver hydatid disease caused by E.Granulossus with a low rate of complication and recurrence.
Effect of Patient Demographics, Comorbidities, and Medications on Severity of NASH Fibrosis
Non-Alcoholic Fatty Liver DiseaseNon Alcoholic SteatohepatitisFew studies have evaluated an extensive list of possible risk factors for NAFLD for their association with presence and severity of histologic features. We wish to conduct a retrospective study on these possible factors (including demographics, comorbid diseases, and medications) for their association, if any, with severity of histopathologic findings. This study hypothesize that certain risk factors, specifically those contributing to or consisting of metabolic syndrome, will have higher NASH Fibrosis stages.
Mean Systemic Filling Pressure Trends in Liver Transplant Recipients
Liver Transplant; ComplicationsLiver Diseases1 morePatients with end stage liver disease undergoing liver transplantation have varying degrees of intraoperative haemodynamic unstability during various phases of transplantation. It is difficult to determine the cause for hemodynamic instability in these patients and to predict the best treatments. Currently, cardiovascular resuscitation options are triggered by arterial pressure and cardiac output (CO) measures, focusing on the oxygen delivery side of the circulation. The primary determinants of cardiac output reside on the venous side. Veins are 30-50 times more compliant than arteries and contain approximately 75% of the total blood volume. Mean systemic filling pressure provides vital information on this venous side of the circulation. Mean systemic filling pressure , which is defined as the pressure equal to the pressure which would be measured if the heart should suddenly stop pumping and all (arterial and venous) the pressures in the entire circulatory system should be brought to equilibrium instantaneously, is a good, complete and reliable reflection of the total intravascular fluid compartment. We would study the Mean systemic filling pressure in liver transplant recipients and record hemodynamic, respiratory, cardiac and renal function prospectively. Follow up data for 7 days for respiratory, cardiac and renal complications will be collected, along with hospital stay, ICU stay and mortality. The association between Mean systemic filling pressure and these outcomes will be analyzed.
