The Influence of Autophagy on Fatty Liver
Non-alcoholic Fatty Liver DiseaseObesityNon-alcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease worldwide. It is not known why only some obese subjects develop NAFLD. In recent years, a growing body of evidence showed a crucial role of autophagy in in the regulation of liver fat storage. The purpose of this study is to determine whether autophagy pathway-related genetic polymorphisms affect NAFLD.
Longitudinal Study of Mitochondrial Hepatopathies
Acute Liver FailureMitochondrial Diseases4 moreThe specific aims of this study are (1) to determine the clinical phenotypes and natural history of hepatic RC and FAO disorders, (2) to determine the correlation between genotype and phenotype, (3) to determine if circulating biomarkers reflect diagnosis and predict liver disease progression and survival with the native liver, (4) to determine the clinical outcome of these disorders following liver transplantation, and (5) to develop a repository of serum, plasma, urine, tissue and DNA specimens that will be used in ancillary studies. To accomplish these aims, the ChiLDREN investigators at clinical sites (currently 15 sites) will prospectively collect defined data and specimens in a uniform fashion at fixed intervals in a relatively large number of subjects. Clinical information and DNA samples to be collected from subjects and their parents will enhance the potential for meaningful research in these disorders. A biobank of subject specimens and DNA samples will be established for use in ancillary studies to be performed in addition to this study.
The Danish Childhood Obesity Biobank
ObesityMetabolic Disease3 moreThe Danish Childhood Obesity Biobank aims to produce a scientific platform for research in obesity: Bio-clinical data are collected from two cohorts - an obesity clinic cohort and a population-based cohort. The biobank thus facilitates translation between research and clinical practice of obesity treatment and related complications.
Nonalcoholic Fatty Liver Disease in HIV Database
NAFLDNASH - Nonalcoholic Steatohepatitis1 moreNonalcoholic fatty liver disease (NAFLD) is a spectrum of liver conditions associated with fat accumulation that ranges from benign, non-progressive liver fat accumulation to severe liver injury, cirrhosis, and liver failure. The spectrum of NAFLD encompasses simple nonalcoholic steatosis (nonalcoholic fatty liver [NAFL]) and nonalcoholic steatohepatitis (NASH) in which there is evidence of hepatocellular injury and/or fibrosis. NAFLD is the most common liver disease in adults and the second leading cause for liver transplantation in the U.S. The natural history of NAFLD in the general population has been well described. The NASH Clinical Research Network (NASH CRN) was established by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) in 2002 to further the understanding of the diagnosis, mechanisms, progression and therapies of NASH. This effort has resulted in numerous seminal studies in the field. However, NASH CRN studies have systematically excluded persons living with HIV (PLWH) , as NAFLD in PLWH was thought to be different from that in the general population due to HIV infection, antiretroviral therapy (ART), concomitant medications and co-infections. This resulted in major knowledge gaps regarding NAFLD in the setting of HIV infection. Thus, the natural history of NAFLD in PLWH is largely unknown. The goal of this ancillary study of NAFLD and NASH in Adults with HIV (HIV NASH CRN), is to conduct a prospective, observational, multicenter study of NAFLD in PLWH (HIV-associated NAFLD).
Safety and Immune Response of COVID-19 Vaccination in Patients With Chronic Liver Diseases
Liver DiseasesCovid191 moreOn 11 February 2020, the International Committee for the Classification of Viruses named the disease caused by SARS-CoV-2 infection in humans as the new coronavirus pneumonia (coronavirus disease 2019, COVID-19). Due to the characteristics of liver microcirculation disturbance and immune function disorder in patients with chronic liver diseases (such as immune liver disease, chronic hepatitis C, liver cirrhosis, liver cancer, etc.), those patients has a higher risk of infection than the general population during the epidemic period. More attention should be paid to personal protection and disease prevention. Vaccination of COVID-19 vaccine can effectively prevent COVID-19 virus infection and delay or prevent patients from developing into critical illness and reduce mortality. To evaluate the safety and effectiveness of COVID-19 vaccine in those patients with chronic liver diseases, and to guide the COVID-19 vaccination more scientifically, reasonably and effectively, this study was carried out.

The Sonic Incytes Liver Incytes System, Evaluation of Liver Fibrosis and Steatosis Versus MRE and...
Non-Alcoholic Fatty Liver Disease (NAFLD)Non-Alcoholic Steatohepatitis (NASH)2 moreThe main purpose of this study is to compare the effectiveness of various non-invasive elastography techniques at determining liver stiffness measures in human subjects. Specifically, the investigators are comparing MRE and FibroScan to Vibroelastography (VE, Liver Incytes System). These techniques are used to measure stiffness in the liver.
Quantitative Ultrasound Techniques for Diagnosis of Nonalcoholic Steatohepatitis
Nonalcoholic Fatty Liver Disease (NAFLD)Nonalcoholic Steatohepatitis (NASH)Nonalcoholic fatty liver disease is the most common liver disease in Western countries, due in large part to its association with type 2 diabetes and obesity. The more advanced form of this disease is known as nonalcoholic steatohepatitis (NASH). If left untreated, NASH can evolve to cirrhosis, the late stage of fibrosis. Once cirrhosis is established, patients are at increased risk of developing gastrointestinal bleeding, liver cancer and liver failure that may require transplantation. A liver biopsy is currently needed to diagnose the severity of fatty liver disease but this is usually not indicated in asymptomatic patients. This procedure requires the insertion of a needle inside the liver to remove a small piece of tissue for examination under microscope. Liver biopsy is an invasive procedure with a small risk of major complications such as bleeding in 0.5% of cases. It is also affected by sub-optimal sampling leading to diagnostic errors Ultrasound is optimum for screening patients with or without symptoms because it is a safe and widely available technology to scan the whole liver. Members of our team have developed Advanced ultrasound techniques that provide unique information not possible with state-of-the-art techniques. Unlike liver biopsy, these techniques would be applicable even in asymptomatic patients because it is non-invasive. This research proposal proposes a novel approach for diagnosis of NASH and will be the first study to measure individual components of NASH (fat, inflammation and fibrosis) with quantitative ultrasound (QUS) scores. This study is timely because NASH is the second leading cause of liver transplantation in North America and is predicted to become the leading indication in the near future.
MRI Biomarkers in as Predictor of Clinical Endpoints in Pediatric Autoimmune Liver Disease
Autoimmune Liver DiseaseAutoimmune Hepatitis1 moreAutoimmune liver diseases (AILD), which include Primary Sclerosing Cholangitis (PSC) and Autoimmune Hepatitis (AIH) are a common etiological factor for chronic liver disease among adolescents. This is a longitudinal study to identify surrogate endpoints with an accurate predictive value for the progression of hepatobiliary damage in subjects with pediatric onset AILD. This study will involve collection of MRI-based data at the time of enrollment and at year 1 and 2 of follow up, and collection of clinical data for 10 years following enrollment. There is a strong possibility that MRI quantitative techniques may be more sensitive to disease progression than standard clinical and laboratory tests. To investigate predictivity of MRI based biomarkers, summary measures of MRCP/MREL from baseline, Year 1 and Year 2, e.g. change rate, maximum, and average will be calculated as predictors for Year 10 clinical outcomes. The same predictors will also be used to model native liver survival in a proportional hazard regression. Findings from this study may be used to assess disease progression and to predict complications and survival of liver disease patients.
