Filter by:Malnutrition is prevalent among chronic liver disease patients. Inadequate ingestion and/or metabolic alterations modify the body composition and biological functions. The purpose of this study is to determine whether whey protein comsumption, due to amino acid profile, digestibility and bioactive compounds may be beneficial for patients waiting for liver transplantation
The purpose of this study is to further evaluate the immunogenicity and safety of 10μg/0.5ml Recombinant Hepatitis B Vaccines(Saccharomyces Cerevisiae) in the Healthy Neonates.
Human immunodeficiency virus (HIV) infection is a major global health issue with up to 40 million people infected worldwide. Due to highly active antiretroviral therapy, mortality related to acquired immunodeficiency syndrome (AIDS) has been reducing in the last decades. However, liver disease remains as an important cause of severe complications and death. Hepatic fibrosis progression is the main responsible for liver-related outcomes in HIV-positive patients. Co-infection by hepatitis B (HBV) or hepatitis C virus (HCV) is highly prevalence in HIV patients. Chronic viral co-infection induces faster liver fibrosis progression compared to mono-infected HIV. However, published data have been reporting presence of significant liver fibrosis in HIV without HBV or HCV infection. This might be related to direct action of HIV in hepatocytes or association with others factors, such as non-alcoholic fatty liver disease (NAFLD). NAFLD is associated with metabolic factors, such as obesity and type-2 diabetes mellitus. However, antiretroviral drugs may induce abnormal body fat distribution (lipodistrophy) and insulin resistance playing an important role on this process. Liver biopsy has been historically considered as the gold standard to evaluate liver injury. However, this painful method presents several limitations. Therefore, several non-invasive methods for estimation of liver fibrosis, such as biomarkers (APRI, FIB-4, FibroTest and FibroMeter) and transient elastography by Fibroscan, have been developed as an alternative to liver biopsy. The diagnostic performance and prognostic value of biomarkers and transient elastography have been validated in patients with chronic liver diseases. However, few data are available in HIV patients, especially in those without chronic viral co-infection. Therefore, patients, medical doctors and scientific community will be beneficiated by the future application of non-invasive methods for estimation of liver injury in clinical practice in HIV patients.
Patients who accept long-term parenteral nutrition tend to suffer from liver injury. The mechanism for this injury has two possible explanations. The first possible reason is intrinsic toxic effects of parenteral nutrition. The second is the basic pathological condition of intestinal failure which includes infection, bacterial translocation, etc. Cholestasis is the lethal presentation of this kind of liver disease. Farnesoid X receptor (FXR) is a member of ligand-activated nuclear receptor superfamily. FXR serves as a sensor for bile acids and promotes enterohepatic clearance of bile acids by controlling the expression of genes involved in their transport and metabolism. Considering the activation of vitamin D receptor (VDR) by vitamin D can induce FXR-related genes in the liver.The hypothesis of this study is that vitamin D plays a key role in the prevention and reversion of the liver via VDR and/or FXR signaling pathway. Using a mouse cholestasis model based on short bowel syndrome and parenteral nutrition, the researchers will investigate the dynamic change of plasma vitamin D level. Afterward, intravenous supplement of vitamin D was added to this model to demonstrate vitamin D can ameliorate cholestasis. An in vitro system was developed to investigate the importance of FXR signaling pathway in this effect.
Visceral obesity and adipose inflammation is considered a driving force of obesity-related systemic disease, e.g. cardiometabolic disease, liver cirrhosis and chronic kidney disease (CKD). Inflammatory resolution is actively regulated by specialized pro-resolving mediators (SPMs), including the endogenous eicosanoid LXA4. Impairment of SPMs may underlie development of obesity-related pathology.We hypothesize that obese patients who develop obesity-related disease do so because they suffer from impaired endogenous production of pro-resolving lipids. This will result in aggravated adipose inflammation and fibrosis, which contribute to the systemic pathologies. We thus wish to investigate adipose inflammation and the pro-resolving lipid profile of obese subjects with and without obesity associated metabolic disease. We also aim to investigate whether LXA4, LXB4 and other anti-inflammatory agents (such as AICAR) can alter the phenotype of human adipose macrophages in ex vivo tissue culture. We also investigate basic pathways in inflammatory regulation and obesity related cardiometabolic disease.
The objective of the SIM trial is to investigate whether using the Surefire Infusion System during holmium-166 radioembolization increases the posttreatment tumor to non-tumor activity concentration ratio, compared with using a standard end-hole microcatheter.
The aim of the present study is to evaluate whether the use of indocyanine green fluorescent cholangiography is responsible in a decrease of biliary fistula's rate in patients with liver diseases requiring liver resection.
The purpose of this study is to validate the first round HCV early dynamics discovery within a larger population.
Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease in the United States. The cause of NAFLD is poorly defined but is thought to involve complex interactions of genetic and environmental factors. NAFLD is often associated with the traits of the metabolic syndrome including diabetes, high cholesterol or elevated blood pressure. Currently, there are no accurate noninvasive means of evaluating NAFLD and its more serious form which includes inflammation that may lead to severe scarring in the liver. The goal of this study is to evaluate shared genetic factors that underlie NAFLD and features of the metabolic syndrome as determined by blood work and radiographic studies in a cohort of twins and first degree relatives.
The purpose of this research is to compare the classical procedure with intrahepatic Glisson's approach for laparoscopic anatomical hepatectomy. The validity, feasibility and limitations were assessed objectively through our clinical prospective study. The investigators expect laparoscopic anatomical hepatectomy with intrahepatic Glisson's approach is safe, effective and feasible.
