Filter by:This study will follow-up a cohort of patients from the Birmingham and Lambeth Liver Evaluation Strategies (BALLETS) study using a database search based on their individual National Health Service (NHS) numbers. The investigators will interrogate the Hospital Episode Statistics database and the Office of National Statistics database, and examine three categories of end points: death, inpatient attendance primarily due to liver disease, and outpatient attendance primarily due to liver disease. A logistic regression analysis will then be conducted to determine associations between these end points and the presence, and degree, of fatty liver in the original BALLETS study, adjusted for age, sex, alcohol intake, BMI, and baseline ALT measurement.
Major abdominal surgery - like non-laparoscopic bowel resection, liver, gastric, or pancreas surgery - is performed under general anesthesia. Pain control for after the surgery can be achieved purely with intravenous and oral pain medication or in combination with freezing of the nerves. Nerve freezing (nerve block) placed before surgery has the potential to substantially reduce the amount of inhaled anesthetic given to the patient during surgery. This can benefit the patient with being more awake and crisp more quickly after surgery. It can also reduce cost to the system. A further benefit which has received very little attention so far, is that reducing the amount of inhaled anesthetic given also lowers the environmental footprint created by the anesthetic. The investigators of the proposed study plan to quantify the amount of inhaled anesthetic used for each case and will compare how the consumption is affected by whether the epidural block is applied before or after surgery. Patients will have a nerve block catheter (epidural catheter) placed prior to the induction of general anesthetic by an experienced regional anesthesiologist. The epidural catheter will be bolused with a solution to which the anesthesiologist is blinded which will either be local anesthetic or dextrose (sham). The general anesthetic will be conducted according to a the protocol with the aim of maintaining a standard anesthetic depth monitored by patient state index (PSI). Measurements of the MAC-Value (minimum alveolar concentration) of inhaled anesthetic will be recorded every five minutes and will be noted down by a blinded observer. At the end of the case the anesthesiologist blinded to the solution will inject another solution (now a dextrose (sham) or local anesthetic before the patient is woken up.
The gut microbiota is critical to health and functions with a level of complexity comparable to that of an organ system. Dysbiosis, or alterations of this gut microbiota ecology, have been implicated in a number of disease states. Fecal microbiota transplantation (FMT), defined as infusion of feces from healthy donors to affected subjects, is a method to restore a balanced gut microbiota and has attracted great interest in recent years due to its efficacy and ease of use. FMT is now recommended as the most effective therapy for CDI not responding to standard therapies. Recent studies have suggested that dysbiosis is associated with a variety of disorders, and that FMT could be a useful treatment. Randomized controlled trial has been conducted in a number of disorders and shown positive results, including alcoholic hepatitis, Crohn's disease (CD), ulcerative colitis (UC), pouchitis, irritable bowel syndrome (IBS), hepatic encephalopathy and metabolic syndrome. Case series/reports and pilot studies has shown positive results in other disorders including Celiac disease, functional dyspepsia, constipation, metabolic syndrome such as diabetes mellitus, multidrug-resistant, hepatic encephalopathy, multiple sclerosis, pseudo-obstruction, carbapenem-resistant Enterobacteriaceae (CRE) or Vancomycin-resistant Enterococci (VRE) infection, radiation-induced toxicity, multiple organ dysfunction, dysbiotic bowel syndrome, MRSA enteritis, Pseudomembranous enteritis, idiopathic thrombocytopenic purpura (ITP), and atopy. Despite FMT appears to be relatively safe and efficacious in treating a wide range of disease, its safety and efficacy in a usual clinical setting is unknown. More data is required to confirm safety and efficacy of FMT. Therefore, the investigators aim to conduct a pilot study to investigate the efficacy and safety of FMT in a variety of dysbiosis-associated disorder.
This randomised controlled trial will determine if exercise (150 - 200 min per week, 6 weeks) can beneficially modify liver fat quality in non alcohol fatty liver disease patients with type 2 diabetes mellitus (n = 26, 13 per group). Liver fat quality will be assessed via magnetic resonance (3T) spectroscopy (1H-MRS) using validated methods.
A defect of the immune response has been described in patients with severe liver disease. This immune-paresis is partly driven by a compensatory anti-inflammatory response following a systemic inflammatory response syndrome and affects the innate immune response. The innate immune defect has been described in patients with advanced cirrhosis and more significantly in patients with acute liver failure or acute on chronic liver failure (ACLF). The monocytes/macrophages pro-inflammatory response and finally the antimicrobial response are thus strongly impaired, leading to higher sepsis risk. The monocytes/macrophages phenotype associated with these functional alterations has been widely described, with a weaker expression of Human Leukocyte Antigen - DR isotype (HLA-DR) on the monocytes surface, correlated with poor outcomes. The low monocytic expression of HLA-DR, its functional and clinical impact has been widely described in the context of septic shock with similar pathophysiological mechanisms. Liver transplantation (LT) is often the only therapeutic option for patients with advanced liver failure. Post-transplant survival of the most severe patients is similar to the survival in the whole population of LT patients, but the complication rate remains higher, with a major risk of infection. Currently used immunosuppression protocols do not take into account the quality of pre-transplant immune response. Some treatments, such as corticosteroids, which are widely used for the induction of post-transplant immunosuppression, may affect the innate immune response. However, it has been shown that low expression of post-transplant monocyte HLA-DR was associated with a greater risk of septic complication. The general objective of this study is to focus on the evolution of a robust marker of immune dysfunction, HLA-DR monocyte expression, before and following LT, and to analyse its post LT expression depending on the level of pre-transplant expression as well as its association with post-transplant complications. This study will bring new insights for the design of a prospective study on the relevance of adapting post-transplant immunosuppression protocols to HLA-DR expression on monocytes surface, which is a robust marker of the innate immune response. Evaluation of innate immune dysfunction pre-LT by quantification of monocytic HLA-DR expression and monitoring of its post-LT kinetics may be relevant for assessing post-transplant immune status and adapting immunosuppressive therapy. A descriptive, observational study associating clinical and biological data is needed to confirm the relevance of HLA-DR expression quantification on the surface of monocytes in a population of selected patients, before and after LT. These data will allow setting up a prospective interventional study reporting the possible benefit of post-transplant immunosuppressive treatment modulation, according to the HLA-DR monocyte dosage and its kinetics evolution. The main objective of this study is to describe the association between evolution of monocytic HLA-DR expression on monocytes/macrophages surface during the first month after LT and the occurrence of one of the 2 following clinical events reflecting a post LT immune dysfunction (acute cell rejection and sepsis).
This study is a randomized pilot seeking to address low patient adherence to a low sodium diet as a strategy to improve outcomes of patients with cirrhosis of the liver. In coordination with the Metropolitan Area Neighborhood Nutrition Alliance (MANNA) of Philadelphia, patients in the intervention cohort will receive low sodium MANNA meals to encourage improved dietary compliance. Outcomes of these interventional patients will be compared to those receiving standard of care--namely, educational intervention by physicians supplemented by occasional counseling from dieticians during clinic visits encouraging a low sodium diet. Dietary compliance will be evaluated by urine sodium and salt affinity tests and used as a positive marker for improved outcomes. The target population of this study is patients diagnosed with cirrhosis of the liver, aged 18-85 years living within the MANNA-serviced area.
This study is a randomized controlled trial comparing a simple telehealth intervention implemented after hospital discharge to standard of care, specifically looking at the number of hospital readmissions throughout the course of the study. All cirrhotic patients admitted to the Hepatology service at The Hospital of the University of Pennsylvania will be approached and consenting patients will be randomized to one of the two arms as outlined below. Patients will be followed for 90 days with daily texts and weekly phone calls. The rates of 30 and 90 day readmission as well as the days to readmission will be compared between the two study groups.
The aim of this study is to determine the risk factors for major complications following liver resection in the setting of a general surgery-teaching department in Morocco, North Africa
The main aim of this single-site prospective study is to use serum liver function tests and FibroScan as assessment tools to measure liver disease in pregnant women with or without liver disease at King's College Hospital. This will be assessed during each trimester of pregnancy. FibroScan will assess liver stiffness in these participants and will be used as a surrogate marker for fibrosis.
The purpose of this study is to determine whether patients with stage 1-3 NASH-related fibrosis are able to complete a single vigorous-intensity interval training (VIIT) session on an indoor rowing machine and provide blood samples before and afterwards. The results of this study will provide the foundation for future research on the role of VIIT in treating NASH.
