Active clinical trials for "Liver Diseases"

Patient with Advanced Chronic Liver Disease often present portal hypertension which may lead to bleading or ascites. One of the treatment of portal hypertension in these patients is the placement of a Transjugular Intrahepatic Portosystemic Shunt (TIPS). The indications for placing TIPS take on various clinical presentations, the most classic being digestive haemorrhage by rupture of oesophageal and/or gastric varices and refractory ascites. TIPS placement involves changes in haemodynamics and liver function that may alter the patients' condition and quality of life. Very few articles have evaluated the quality of life of these patients and when quality of life is evaluated it is mostly with not adapted or not validated scales. The main objective of this study is to evaluate the quality of life of patients who have undergone TIPS using a validated and standardised quality of life questionnaire (the SF-36 questionnaire).

The investigators use machine learning capabilities on massive electronic health records for the purpose of developing a model that prioritizes individuals at high risk of progressing to liver cirrhosis, and validating it with participants that the model found to be at high risk. constructing and validating a reliable model, with sufficient accuracy to justify further and expensive means of detection, will enable treating patients with damaged liver at an early enough stage to allow improvement of the liver condition.

The global rise in the prevalence of obesity paved the way for the increased prevalence of yet another obesity-related complication significant enough to be considered within the roster of major public health threats: non-alcoholic fatty liver disease (NAFLD). In this follow-up study, the investigators will attempt to decipher the natural history of hepatic steatosis among patients with type 2 diabetes mellitus (T2DM) using state-of-the-art methods in a well-characterized Saudi cohort. The investigators aim also to validate existing biomarkers of disease severity and explore the pathogenesis of progressive disease using metabolic profiling technologies. A total of 1000 adult Saudi patients (males and females) with T2DM will be recruited. Those with co-morbidities, including hepatic decompensation, will be excluded. Participants will be followed three times for a total of 10 years/patient (Year 2, Year 5, and Year 10), and measures such as dietary evaluations, anthropometrics, and urine, stool, and blood examinations will be performed. Patients who develop NAFLD will be noted, and patterns/changes in the metabolic profile will be examined. For this specific grant (the first 2 years of the whole project), the investigators will be able to recruit the study cohort, do the baseline anthropometric, imaging, and biochemical measurements, and report the prevalence of NAFLD among patients with T2DM. This information will be the basis of subsequent follow-up and allow for validating potential diagnostic and prognostic biomarkers. This project will be of high importance at the national level since it will create awareness in the local medical community of the current severity status of NAFLD in the kingdom and will be used as a tool to promote public health awareness in the community.

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 aim of this retrospective and prospective study is to evaluate the 20-year prognosis value of non-invasive methods for the diagnosis of chronic liver disease for predicting survival and complications of cirrhosis.

The purpose of this study is to identify individuals who have suffered a liver injury arising as an idiosyncratic reaction to a prescription drug or a complementary and alternative medicine. Recently added acute cases enrollment that meets criteria to the protocol. Also added Fibroscans to the protocol that will be completed at baseline and follow-up on chronic subjects.

Chronic hepatitis B (CHB) affects an estimated 292 million people, and causes approximately 800,000 people deaths per year from liver-related complications including cirrhosis and hepatocellular carcinoma, remaining a major global public health issue.Meanwhile, with the improvement of living standards and changes in lifestyle and dietary habits, non-alcoholic fatty liver disease (NAFLD) has become another important cause of liver cirrhosis and HCC.HBV combined with NAFLD inevitably develops into continuous or intermittent liver inflammation and fibrosis, which greatly increases the risk of cirrhosis, liver cancer and even end-stage liver disease. We aimed to investigate the risk factors and establish diagnostic models for hepatic inflammation, fibrosis in patients with CHB associated NAFLD. In addition, to find risk factors for liver cirrhosis, liver cancer or liver failure in patients with CHB-related NAFLD.

This research study is being conducted to find out more about techniques to non-invasively evaluate liver disease. The investigators are testing a new technology to evaluate the liver (LiverScope®), and they will compare it to other methods to evaluate the liver, including advanced conventional liver MR and liver FibroScan® ultrasound exams. MR exams and FibroScan® ultrasound exams are common exams used to monitor NAFLD. Conventional MR scanners use magnetic fields and radio waves to make pictures of the liver. LiverScope® is a small, portable MR-based device that uses similar, but simplified technology, and can be used on top of an exam table in an outpatient setting. LiverScope® currently is not approved for clinical use. In this study the investigators will learn how LiverScope® measurements of the liver compare to MR. Study participants will be asked to complete a one-time visit which includes: LiverScope exam MR exam FibroScan exam (optional) Blood draw Completion of study questionnaires

The investigators will conduct an open label, experimental medicine study exploring the diurnal patterns of hepatic lipid metabolism in NAFLD and non-NAFLD participants (determined by Transient elastography (TE) with controlled attenuation parameter (CAP)). We will also determine whether the diurnal patterns of lipid metabolism in NAFLD participants can be modified using lifestyle and weight loss intervention. Fourteen participants without NAFLD will have morning and evening metabolic investigations (visit 1M & 1E) to assess for changes in lipid flux pathways across the course of the day. After morning and evening investigations their involvement in the clinical study will then end. Seventeen NAFLD participants will also have identical baseline morning and evening investigation after which they will be enrolled into a 12-week lifestyle and weight loss programme. After 12-weeks, all 17 participants with NAFLD will have a follow up CAP, and morning and evening metabolic investigations (visit 2M & 2E).
