Filter by:Liver transplantation (LT) is a current life-saving procedure performed as an open-abdominal surgery for patients with end-stage liver diseases (ESLD). However, a high risk of post-surgical complications is relevant to major intra-abdominal interventions. In managing post-LT recovery, it is important to consider the extending pre-transplant physical status of ESLD patients concerning an impaired exercise capacity, a prolonged period of deconditioning, fatigue and muscle weakness, which leads to global motor impairment and decreased functional capacity. Sarcopenia and physical deconditioning are known as the hallmark features of ESLD. The quality and the quantity of skeletal muscle mass have been closely correlated with post-transplantation mortality in individuals undergoing LT. In addition to chronic deconditioning or myopathy related to chronic liver failure, post-transplant immunosuppressive medication contributes to increased risk for age-related decline in muscular strength and physical ability. It reportedly persists impaired physical function including reduced muscle strength, which have been consistently associated with impaired quality of life after a liver transplant. Exercise interventions in solid-organ recipients provide improvements in physical function including skeletal muscle strength. The literature has defined many types of exercise-based interventions including aerobic and resistive training or physical activity counselling in improving physical performance tasks, muscle strength and physical domain of quality of life in postoperative liver transplanted adults. Although there are studies in improving muscle performance and functional status, no study conducted in the post-transplant early period and an optimal exercise regimen for post-liver recipients. In the present study, it will be provided a framework for a possible change in practice aiming to improve muscle strength and functionality in liver recipients through a strength training exercise intervention at the early post-transplant period. The purposes of this trial were: 1) to evaluate the feasibility and safety of a strength exercise training program on functional mobility and quality of life of liver transplanted individuals and 2) to initiate physiotherapy protocols in this population. A key component of this approach was that it was individualized, providing one-to-one therapy with tailored progression specific to a person's individual mobility goals.
Major liver surgery is associated with increased incidence of perioperative complications and increased mortality if these are not addressed quickly in a high dependency intensive care unit. Of these, posthepatectomy liver failure (PHLF) represents one of the most important cause of postoperative unfavourable outcome. The present study investigates the correlation between lactate levels and PHLF. Lactate levels were collected at six specific timepoints: preoperative, pre-dissection phase, post-dissection phase, end of surgery and 24-hours and 48-hours in the postoperative period.
Hemoadsorption has been demonstrated to improve liver functional tests in patients with liver failure. The present study investigates the effects of three consecutive sessions of hemoadsorption, performed in accordance to the local protocol for treating patients with acute liver failure, on liver functional tests, severity scores and 30-days mortality. Paraclinical results and severity scores were obtained before and after the three consecutive sessions.
Acute on chronic liver failure (ACLF) is a distinct entity where, because of severe acute hepatic injury, a rapid loss of liver function develops in a patient with previous chronic liver disease(4). These patients have severe hepatic dysfunction, and outcome is defined by functional hepatic reserve and extent of extra-hepatic organ failures(5). Renal failure is a frequent extra-hepatic organ failure, and its presence is an independent prognostic marker for mortality(12). The pathophysiological basis of renal dysfunction in patients with ACLF is different compared to those with decompensated cirrhosis (DC)(6). Systemic inflammation is the hallmark of ACLF, characterized by a cytokine storm wherein there is an increase in both pro- and anti-inflammatory cytokines, such as interleukin (IL)-6, IL-8, IL-1β, and IL-10, leading to circulatory dysfunction and organ failure(3). These patients therefore have a higher incidence and progression of acute kidney injury (AKI). Diagnosis of HRS-AKI in ACLF currently requires 48 h of volume repletion with albumin and diuretic withdrawal. Therefore waiting for 48 hours to start treatment with terlipressin can be associated with worsening of AKI stage, worsening of ACLF stage and thereby suboptimal treatment response and high mortality despite treatment response. Therefore early initiation of terlipressin as continuous infusion after volume repletion with IV albumin in ACLF-AKI is safe and prevents AKI progression by splanchnic vasoconstriction and improved renal perfusion.
Bowel colonization with anti-microbial resistant bacteria increases the risk of clinical infections. Infections caused by anti-microbial resistant bacteria have been associated with increased mortality, prolonged hospital stay, and increased costs. In addition, with the emergence of carbapenemase resistant bacterial species, there may not be any effective therapy for patients infected with such resistant species. Bowel colonization with anti-microbial resistant bacteria is an established risk factor for infections due to resistant bacteria, especially in transplanted patients and in intensive care unit. In this study we will study whether bowel colonisation in Acute on Chronic Liver Failure patient increases the risk of infection development in extra intestinal sites.
The purpose of this study is to determine if medically tailored meals provided for either 2 weeks or 4 weeks (1 meal per day) to a Kaiser Permanente Colorado (KPCO) member after hospital discharge will improve their health. Medically tailored meals (MTM) are meals that are approved by a dietitian and shown to help people with certain health conditions.
Intravenous lipid emulsion (ILE) is an essential component of parenteral nutrition (PN), but also one of the key risk factors for development of intestinal failure associated liver disease (IFALD). The aim of the study was to analyse the influence of ILEs on liver function during long term PN.
Background: Patients with cirrhosis and acute-on-chronic liver failure (ACLF) may have bleeding complications which can lead to increased mortality. Standard coagulation tests (SCTs) like prothrombin time, platelet count and activated partial thromboplastin do not accurately depict in vivo coagulation profile. Point-of-care viscoelastic coagulation testing devices like thrombo-elastography (TEG) and Sonoclot may be better for guiding patient management. Methods: This prospective observational study compared and validated the point of care (POC) tests and SCTs in 70, 72 and 25 persons with ACLF, decompensated cirrhosis and healthy controls respectively.
This study analyses the effect of intravenous branched chain amino acids (BCAA) on overt HE in patients with ACLF. The investigators plan to study the efficacy of combining intravenous BCAA with lactulose versus lactulose alone in the medical management of overt HE in patients with ACLF and its impact on overall survival and improvement in grade of HE.
Background: Previous studies have documented differences in the pharmacokinetics (PK) of a once daily FK506 formulation (Advagraf) based on patient ethnicity. These findings may be of particular relevance to the First Nations population who constitute a large and increasing segment of the liver transplant population in Canada. Aim: The purpose of the present study is to determine whether PK differences exist for Advagraf in First Nations compared to Caucasian liver transplant patients. Objectives: 1. Document and compare PK determinations for Advagraf in First Nations and Caucasian patients with stable liver transplants. 2. Document and compare CYP3A gene expression profiles in the two ethnic populations. Study Design: - single-centre, open-label - consecutive enrollment (N=8/group) - self-identified adult First Nations and Caucasian ethnic cohorts - 7 day steady state conversion (mg/mg/day) from twice to once daily FK506 formulation - timed blood samples at 0, 1.5, 2, 4, 6, and 24 hours post medication - PK determinations:concentration at zero time (C0), time to maximum concentration (Tmax),Area Under the Curve (AUC 0-24), apparent oral clearance (CLoral) and maximum concentration (Cmax) Methods: - whole blood FK506 levels will be measured by UPLC tandem mass spectroscopy - CYP3A allele analyses will be performed by Dr. Richard Kim, University of Western Ontario Relevance: The results of this study will serve to determine whether present guidelines for conversion of twice to once daily FK506 formulations need be modified for First Nations liver transplant patients.
