Filter by: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 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 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.
Several drugs and chemotherapies seem to have an impact on the hepatological system. This study investigates reports of hepatological toxicities, including the International classification of disease ICD-10 for treatments in the World Health Organization (WHO) global Individual Case Safety Report (ICSR) database (VigiBase).
Pevonedistat is a medicine to treat people with blood cancers or solid tumors. The main aim of the study is to learn about the levels of pevonedistat in the blood of participants with blood cancers or solid tumors, who also have severe kidney problems or mild to moderate liver problems. The information from this study will be used to work out the best dose of pevonedistat to give people with these conditions in future studies. At the first visit, the study doctor will check who can take part in the study. This study is in 2 parts: A and B. Part A Participants will be placed into 1 of 4 treatment groups depending on how severe their kidney and liver problems are. All participants will receive 1 dose of pevonedistat as a slow injection in their vein (infusion). Then, the study doctors will check the levels of pevonedistat in the blood of the participants for 3 days after the infusion. They will also check if the participants have any side effects from pevonedistat. Participants will be asked to continue to Part B. Those who don't want to continue will visit the clinic 30 days later for a final check-up. Part B Participants who agree to participate into Part B will receive an infusion of pevonedistat on specific days during a 21-day or 28-day cycle. The cycle time will depend on what type of cancer the participants have. Participants will also be treated with standard of care medicines for their kidney and liver problems during this time. In the first cycle, the study doctors will also check the levels of pevonedistat in the blood and urine of participants for 3 days after the infusion. Participants will continue with cycles of treatment together with standard of care medicines until their condition gets worse or they have too many side effects from the treatment. When treatment has finished, participants will visit the clinic 10 days later for a final check-up.
This study aims to determine the repeatability and reproducibility of Quantitative Magnetic Resonance Cholangiopancreatography (MRCP). Imaging scientists at Perspectum Diagnostics have developed a hessian-based mathematical model to enhance conventional MRCP to a 3D geometric model of the biliary tree, 'Quantitative MRCP'. This enables advanced quantitative measurement of bile duct width, orientation, branching point and curvative metrics. The technology has been validated against 3D printed phantoms for accuracy, and early clinical research has demonstrated the technology has potential for clinical impact, with improvement in radiologist performance versus conventional non-enhanced MRCP imaging (Vikal et al 2017). Quantitative MRCP aims to act as a tool to not only improve assessment of the current status of the biliary tree, but also act as a mechanism to track change within the ducts. Thus, it must be established that any change between scans is due to change in the physiology of the individual and not due to a quirk or fault of the technology. In order to achieve this a series of scans will be performed on an individual over a short period of time, for which the condition of the biliary tree within that individual can be assumed to be constant. Between each scan, subject and coil repositioning will occur. The study will recruit a group of adult volunteers, from both diseased groups and healthy groups in order to achieve a range of physiological biliary metrics.
The purpose of this randomized trial is to examine the effects of a ketogenic diet on non-alcoholic fatty liver disease (NAFLD). Twenty-four participants with NAFLD will be randomized to receive a ketogenic meal plan or control (standard weight loss meal plan). Participants will be followed up to 28 days after initiation of the diet intervention.
ERAS protocols have been utilized extensively in abdominal and non abdominal surgery over the past 20 years. These protocols incorporate evidence based, multi-disciplinary peri-operative care components. Compliance with these protocols is associated with reduced length of stay, reduced morbidity and reduced hospital costs. ERAS protocols within HPB units are les well established with less evidence supporting their use. Liver resection protocols are increasing in use, but ERAS post Whipples resection is less established. In the HPB unit at the Royal Infirmary of Edinburgh, the liver HPB protocol is in use but a recent audit identified that that the compliance rate is low with compliance rates as low as 30 per cent in some care domains.
Mexico occupies the first place worldwide in childhood obesity. Its urban and indigenous communities present different levels of westernization which have triggered different epidemiological diseases. This study aims to treat and prevent obesity and related diseases. A school-based multi-component intervention program is developed in three ethnic groups with varying levels of westernization: Mestizos, Seris and Yaquis. Measurements are obtained to evaluate obesity, cardiovascular, diabetes risk, hepatic and renal function, and physical fitness. The intervention consists on Physical Activity (PA), Health Education (HE) and Nutrition (NP) programs carried out in six urban (Mestizo ethnic group) and indigenous schools (Seri and Yaqui ethnic groups). A total of 800 participants were part of the PA and HE programs (Education Arm), and 117 of them were also part of the NP program (Nutrition Arm). Measurement differences, after and before treatments are used to assess the intervention effect by age, sex, ethnicity, nutritional status, and treatments. Expanded access is not applicable to this study. The Government's Secretary of Education does not allow developing a plan to share individual data of participants.
