Functional MRI to Determine Severity of Cirrhosis
Liver CirrhosisLiver FibrosisThis is a pilot study to investigate the feasibility of a novel MRI technique to assess the severity of liver cirrhosis and predict complications based on functionality and perfusion measurements whilst maintaining image quality. The principal objective of this pilot study is to assess liver function and the future risk of complications in patients with cirrhosis, using novel techniques and measures based on free-breathing Dynamic Contrast Enhanced MRI. Specifically the investigators will assess: Whether sufficient data can be generated in patients with cirrhosis whilst maintaining image quality, and The dynamic range of DCE-MRI measures in patients with cirrhosis. This pilot study will, if successful, provide sufficient data to support applications for larger studies to evaluate the clinical utility of a DCE-MRI imaging biomarker in patients with cirrhosis.

Usefulness of Multi-parametric, Quantitative MR Imaging for Staging of Hepatic Fibrosis in the Patients...
Liver FibrosisLiver fibrosis has been considered as irreversible change. However, recent study showed that early stage liver fibrosis could be reversible and a lot of new drugs are now developing or developed including anti-viral treatment. Liver biopsy is considered as golden standard for the evaluation of liver fibrosis. But biopsy specimen through biopsy only consists of 1/50000 of the whole liver and heterogeneity of liver fibrosis, accurate diagnosis of liver fibrosis is still challenging. Furthermore, its invasive nature, repeated biopsy is practically almost impossible. Hence, non-invasive diagnosis of liver fibrosis is important. In this study we hypothesized that multi-parametric MR imaging including MR elastography, conventional DWI, and IVIM can predict changes of liver stiffness after anti-viral therapy in patients with chronic liver disease. We will enroll 60 biopsy-proven patients and perform multi-parametric MR imaging at the enrollment and one year later to evaluate changes in quantitative values in MR.
An Observational Cohort Study Evaluating Fatty Liver Disease and Liver Fibrosis in Moderate to Severe...
Psoriasis ChronicLiver Fibrosis2 more• Main objectives and outcome measures. Establish prevalence of and factors contributing to fatty liver disease and liver fibrosis in patients with psoriasis. Fatty liver disease diagnosed via ultrasound. Liver fibrosis diagnosed by liver biopsy or non-invasive tests of fibrosis including transient elastography, ultrasound, serum markers of fibrosis including procollagen-3-N-terminal peptide (P3NP). Evaluate non-invasive markers of liver fibrosis in the psoriasis population. Namely transient elastography, standard liver function tests and P3NP. Evaluate the impact of psoriasis disease severity and comorbidities including metabolic syndrome on response to treatment in patients with psoriasis. Data on co-morbid disease collected through questionnaires and review of medical records. Response to treatment assessed using psoriasis area and severity index (PASI) physician global assessment (PGA) and dermatology life quality index (DLQI). Study population: 380 patients with moderate to severe psoriasis will be prospectively recruited to the study. Chief investigator: Professor Jonathan Barker. Co-investigator: Professor Catherine Smith Sponsor/funding organization: Pfizer and Biomedical Research Centre (BRC) at Guys and St Thomas Hospitals Trust
Acoustic Radiation Force Impulse (ARFI)Technology in Prediction of Liver Fibrosis
Liver FibrosisBackground: In patients with chronic liver diseases, liver fibrosis staging is crucial for hazard evaluation of future disease complication development and thus for the optimal decision making on treatment selections.In the era of antiviral and antifibrotic treatments, clinical and research demands are also increasing for non-invasive surveillance of liver fibrosis to evaluate the progression or regression. However, local baseline data on liver stiffness measurement (LSM) using ARFI technique is still lacking in Taiwan, where viral hepatitides are highly endemic. Aim: Using the ARFI elastosonography, we are dedicated to the aims to recruit patients based on strict but appropriate criteria, to complete the correlation and validity studies between ARFI quantification and the referenced METAVIR fibrosis scoring and to conduct subsequent innovative studies on liver diseases. Materials and Methods: We plan to perform the ARFI quantification for each HBV or HCV-infected patient immediately followed by priorly scheduled conventional liver biopsy for METAVIR scoring during the same session of examination. Statistics: The first year's study using ARFI will focus on the correlation testings and validity studies using receiver operating characteristics.

The Relationship Betweensarcopenia And Myosteatosis With The Natural History Of Liver Cirrhosis...
SarcopeniaSarcopenic Obesity2 moreMalnutrition is a common figure associated with liver cirrhosis. The main component of malnutrition in liver cirrhosis is represented by sarcopenia, a condition of a progressive and generalized loss of muscle mass and strength. Many studies have reported that sarcopenia is an independent predictor of morbidity and mortality in cirrhotic patients. Moreover, cirrhotic patients may develop simultaneous loss of skeletal muscle and gain of adipose tissue, culminating in a condition of "sarcopenic obesity". As highlighted by a recent systematic review and meta-analysis [Van Vgut 2017] all the studies on the impact of sarcopenia/sarcopenic obesity and myosteatosis in cirrhotic patients are retrospective studies, mostly involving non-consecutive patients on the list for liver transplantation. Moreover, most of the studies were produced by non-European centers (Canadians,Americans, and Japanese) that published more papers on the same patient series. All these factors have led to a possible selection bias. Furthermore, the methods used to evaluate sarcopenia and myosteatosis were not homogeneous (the entire muscle area, or area of the psoas or psoas diameter) as well as the cut-offs used. For these reasons, we propose a multicentric observational prospective study aimed at analyzing the impact of sarcopenia, sarcopenic obesity and myosteatosis in cirrhotic patients not listed for liver transplantation. Primary endpoint: - Evaluation of the impact of sarcopenia on the mortality of cirrhotic patients not on the waiting list for liver transplantation. Secondary end-point: Evaluation of the impact of sarcopenic obesity and myosteatosis on the mortality of cirrhotic patients not on the waiting list for liver transplantation. Evaluation of the impact of sarcopenia/sarcopenic obesity and myosteatosis on the development of complications (hepatic encephalopathy, bacterial infections, ascites, GI bleeding) in cirrhotic patients not on the waiting list for liver transplantation. Evaluation of the impact of sarcopenia/sarcopenic obesity and myosteatosis on the number of admissions and the days of hospitalization for such complications. Evaluation of the subcutaneous fat impact on mortality and morbidity of cirrhotic patients not on the waiting list for liver transplantation. Concordance analysis of the various methods used (different cut-off/area psoas vs. area of all muscles) for the diagnosis of sarcopenia through the analysis of CT scan.
Sexual Dysfunction in Patients With Chronic Liver Disease
Liver DiseasesLiver CirrhosisThis project will determine the incidence of sexual dysfunction in patients with chronic liver disease, through questionnaires. The questionnaires have been designed to assess several facets of sexual health, e.g. libido, physical symptoms, depression, etc. 150 patients in our liver outpatient department, and 150 healthy volunteers will be asked to fill in the questionnaire in paper form. The results of this project will be used to produce patient resources, advice sheets and educational materials for patients with chronic liver disease. There is also scope to consider possible interventions in the future to improve sexual dysfunction in patients with chronic liver disease.
