Active clinical trials for "Liver Diseases"

This is a single-center observational study on adolescents to determine predictors of the early steps of the formation of atherosclerosis and to quantify their influence on Intima-Media-Thickness of the carotid artery and the aorta and on the Pulse-Wave Velocity. A long-term follow-up by means of record linkage is furthermore planned to evaluate the effect of early atherosclerosis and the cardiovascular risk profile on future morbidity with a special focus cardio- and cerebrovascular events.

Investigator seeks to determine wether integrating an addiction team into a liver transplantation unit improves the prognosis of patients with alcohol-related liver disease requiring liver transplantation. Our hypothesis is that patients managed by an addiction team before and after liver transplantation have less frequent alcohol relapses, thus decreasing the risk of cardiovascular complications, de novo cancer, recurrence of alcohol-related cirrhosis, and consequently increasing their overall survival.

Frequently patients with advanced liver disease experience physical and emotional symptoms during their hospitalization that can may cause a level of discomfort to both the patient and the family members that surround them. This study involves the early introduction of a team of clinicians that specialize in the lessening (palliation) of many of these discomforting symptoms. This team of clinicians is called the palliative care team and they focus on ways to improve pain and other symptom management and to assist patients and their families in coping with the physical, emotional and social issues associated with a diagnosis of advanced liver disease. The team consists of physicians and advance practice nurses who have been specially trained in the care of patients facing serious illness and their caregivers. The investigators are studying the feasibility of delivering this program, the acceptability and satisfaction with the program, and changes in the quality of life, illness understanding, and symptoms of hospitalized patients who receive the program and their caregivers. The study will use a series of questionnaires to measure the study participants' quality of life, physical symptoms, illness and prognostic understanding, and mood. Study questionnaires will be completed in the hospital, home or clinic. Qualitative interviews will be conducted with hepatology and palliative care clinicians as well as patients and caregivers.

COVID-19 pandemic with SARS-CoV-2 infection has become a global challenge. Though most cases of COVID-19 are mild, the disease can also be fatal. Patients with liver disease are more susceptible to damage from SARS-CoV-2 infection considering their immunocompromised status. Therefore, early inoculation of SARS-CoV-2 vaccine in patients with liver disease is an important protective measure. However, information on the effectiveness and safety of the COVID-19 vaccine for liver disease remains to be determined. This muilticentre study (CHESS2101) aims to study the effectiveness and safety of the COVID-19 vaccination for patients with liver disease.

Liver transplantation are surgeries associated with important bleeding and often require perioperative red blood cell (RBC) transfusions. Overall, between 20 and 85 % of liver transplant recipients receive at least one RBC transfusion during their surgery. Such transfusions are consistently associated with higher morbidity and mortality, although this causal association is still under debate in many surgical populations. Despite the lack of clear causative association between perioperative transfusions and worse outcomes, minimizing bleeding and transfusions is believed to improve postoperative outcomes. Many perioperative variables are associated with higher blood loss and need for perioperative transfusions: liver disease severity, preoperative anemia and coagulopathy, higher cardiac filling pressures and higher fluid administration, among others. However, few perioperative interventions have been shown to reduce bleeding and transfusion requirements in this population. Among them, the use of intraoperative phlebotomies to reduce portal and hepatic venous pressure during the dissection phase is a promising one, also described in liver resection surgery. To further investigate the effects of intraoperative phlebotomies on intraoperative bleeding, perioperative transfusions and mortality, the Principal Investigator will conduct a retrospective cohort study with a propensity score based causal analysis.

Liver transplantation is the only treatment for end-stage liver disease. It is a high-risk surgery that can cause heavy intraoperative bleeding. Bleeding and transfusions of blood products are themselves associated with several postoperative complications. Few data have suggested beneficial interventions that can decrease this bleeding. Such interventions are necessary in order to improve these patients' outcomes. In order to better understand the potential therapeutic targets, a better comprehension of the variables associated with such bleeding is essential. Several previous studies have demonstrated a weak association between usual clotting times and bleeding in this population. However, few studies have evaluated the association between the concentration of fibrinogen and bleeding in this population. The primary objective of this study is to assess the association between preoperative serum fibrinogen concentration and the volume of intraoperative bleeding. The secondary objective is to assess the association between preoperative serum fibrinogen concentration and the number of red blood cell units transfused during the intraoperative and immediate postoperative periods. The hypothesis of the study is that a low concentration of preoperative fibrinogen will be associated with an increase in intraoperative bleeding and red blood cell transfusions.

The study is based on data from morbidly obese patients who fulfilled the criteria for bariatric surgery during 2016-2018 at the Department of Surgery, University Hospital Ostrava, Czech Republic.

This prospective randomized trial evaluates the role of customized dietary and physical activity intervention on the progression of Non-Alcoholic Fatty Liver Disease (NAFLD) in patients with obesity and presenting at least three of the main Metabolic Syndrome traits. The project proposes a personalized nutritional intervention based on a Mediterranean customized diet which introduces plenty of antioxidant and anti-inflammatory bioactive components, coupled with physical activity promotion to prevent and reverse NAFLD among obese patients with metabolic syndrome. This will be compared with two more dietary strategies including a Mediterranean Diet intervention with seven meals a day and the conventional dietary approach proposed by the American Association for the Study of Liver Diseases (AASLD).

The first aim of this study is to assess oxidative stress and nutritional status in patients with elevated liver enzymes who were found to have either simple steatosis (SS) or nonalcoholic steatohepatitis (NASH) or normal histological findings on liver biopsy by measuring liver lipid peroxides and tumor necrosis factor (TNF)-α, liver pathology and immunohistochemistry, liver function tests, liver and red blood cell membrane fatty composition, insulin resistance (IR) parameters, plasma lipid peroxides, plasma antioxidant vitamins and antioxidant power, lipid profile, subject demographics, medical history and medication use. The second aim is to detect differences in hepatic gene expression (messenger RNA, mRNA) and epigenetic regulation (micro RNA, miRNA) between patients with SS or NASH and healthy controls, in addition to determine in patients with non-alcoholic fatty liver disease (NAFLD = SS+NASH combined) whether there is an association between hepatic n-3 PUFA content and gene expression. The third aim is to determine the intestinal microbiome (microbial composition and metagenome) in patients with SS or NASH and healthy controls.

The main purpose of this study is to measure how much of the study drug called baricitinib gets into the blood stream and how long it takes the body to get rid of it. Healthy participants and those with liver disease may enroll. The study will last about 7 days for each participant, not including screening.
