Prehabilitation and Posttransplant Training Program in Liver Transplantation

PreLiveR-T consists of a prospective randomized clinical trial conducted in an adult population that is a candidate for liver transplantation (LT) at the Hospital La Fe Valencia (Spain). The study is structured in three phases: I) Prehabilitation (2 months before LT); II) Training, divided in two successive periods: Supervised training (months 3-6 after LT) and Unsupervised training (6-12 months after LT); III) Long-term follow-up (2 years after LT). Primary outcomes are related to post-surgery evolution (morbidity and mortality, hospitalization length, etc.). As a secondary outcomes are collected those related to: functional capacity, muscle strength and quality of life.

Organ Dysfunction Associated With Intra Abdominal Pressures in Liver Transplantation

Patients with end stage liver disease have varying degrees of intra-abdominal hypertension (IAH) due to the presence of ascites. The perioperative events may either relieve or aggravate the intra-abdominal pressures. Intra-abdominal hypertension has damaging effect on various organ systems. There is an increase in intracranial pressures and a decrease in cerebral perfusion pressures associated with IAH . In the heart, there is an increase of right atrial pressures, increase in systemic vascular resistance and decrease in cardiac output . Pulmonary complications include increase in the peak, mean and plateau airway pressures, with decreased compliance . Renal dysfunction is an early effect of raised intra-abdominal pressure, resulting from decreased renal blood flow, shunting of blood to the medulla, mechanical compression of the kidneys and increased pressures in the renal veins . We would study the intra-abdominal pressures in liver transplant recipients and record hemodynamic, respiratory, cardiac and renal function prospectively. Follow up data for 6 days for neurological, respiratory, cardiac and renal complications will be collected, along with hospital stay, ICU stay and mortality. The association between intra-abdominal pressures and these outcomes will be analysed.

Monocytic Expression of HLA-DR After Liver Transplantation

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).

Prevention of Post-TIPS Hepatic Encephalopathy by Administration of Rifaximin and Lactulose

Rationale: Hepatic encephalopathy (HE) is a major and common complication in patients with liver cirrhosis. HE can be classified in the extensive range of neurocognitive deterioration as minimal HE (MHE), covert HE (grade I), or overt HE (OHE, grade II-IV). Liver cirrhosis is the most common cause of portal hypertension (PH). Patients who develop complications of PH, like variceal bleeding or refractory ascites, can benefit from a Transjugular Intrahepatic Portosystemic Shunt (TIPS) placement. Unfortunately, post-TIPS HE is a common and often severe complication. Incidence of new onset or worsening of HE after TIPS is approximately 20-45%. Currently there is no strategy to prevent post-TIPS HE.

Give a MANNA a Fish, Teach a MANNA to Fish

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.

TIPS Plus Transvenous Obliteration for Gastric Varices

Variceal hemorrhage (VH) from gastric varices (GVs) results in significant morbidity and mortality among patients with liver cirrhosis. In cases of acute bleeding, refractory bleeding, or high risk GVs, the transjugular intrahepatic portosystemic shunt (TIPS) creation and transvenous variceal obliteration procedures have used to treat GVs. While these techniques are effective, each is associated with limitations, including non-trivial rebleeding and hepatic encephalopathy rates for TIPS and aggravation of esophageal varices, development of new or worsening ascites, and formation of difficult to treat ectopic varices for transvenous obliteration. Increasingly, however, TIPS and transvenous obliteration are viewed as complimentary procedures that can be combined to reduce bleeding risk and ameliorate sequelae of portal hypertension. Yet, despite a strong mechanistic basis for their combination, there are few studies investigating the combined effectiveness of TIPS plus transvenous obliteration. Thus, the aim of this single center prospective pilot study is to assess the effectiveness and safety of combined TIPS creation plus transvenous obliteration for the treatment of GVs, with the overall goal of improving the clinical outcomes of patients with VH related to GVs. The work proposed could lead to important advances in the treatment of bleeding complications due to liver cirrhosis.

Cirrhosis Care Alberta (CCAB): A Pragmatic Type II Hybrid Effectiveness Implementation Trial

Liver cirrhosis is the leading cause of morbidity and premature mortality in patients with digestive disease. There are many gaps in care which contribute to a high rate of hospital readmissions (44 percent at 90 days) and inadequate quality of care. Currently, there is a lack of structured processes to initiate best practice support for medical and broader health needs of high risk patients. The cirrhosis care Alberta program (CCAB) is a 3 year multi-component quality improvement initiative which will aim to improve quality of care, reduce acute care utilization and be satisfactory to both patients and providers. Best practice support will be provided in the areas of: Evidence based management of cirrhosis, alcohol use support, frailty, advance care planning, home-hospital-home transitions including standardized outpatient monitoring and structured urgent access for rapid, on-demand outpatient assessment.

Angiotensin 2 for AKI After OLT

Kidney injury is a common complication following liver transplantation and is associated with a higher complication rate and increased risk of death. While there are many factors that likely contribute to kidney injury in the perioperative period, a relative low serum level of angiotensin 2 (Ang 2) (a protein hormone that causes blood vessels to narrow) found in patients with liver cirrhosis (late stage of liver damage) may increase their risk of developing acute kidney injury (sudden episode of kidney failure or damage). We propose to investigate how early administration of Ang 2, a new vasopressor drug approved by the FDA in December 2017 for patients with low blood pressure, during the intra-operative period of liver transplant surgery affects the rate of kidney injury after transplantation. Patients who are deemed appropriate candidates for the study will be randomized 1:1 to the treatment and control groups. The intervention period of the study will occur in the operating room during transplant surgery and will be performed by their anesthesiologists. In the Treatment group, patients will receive Ang 2 infusions in addition to other standard vasopressors while patients in the control group will receive standard vasopressors alone. The infusion of Ang 2 in the treatment group will continue through the duration of the surgery and will be stopped prior to leaving the operating room. Both the treatment group and the control group will then be followed for 14 days to evaluate rates of kidney injury and to look for any complications. The follow up period will be extended to 28 days to look at in-hospital mortality rates in both groups. The daily follow up analysis will occur while the enrolled patients are inpatient following their transplantation surgery and will be done by looking at lab values and other data that is routinely gathered by their managing teams. This study will serve as a pilot study to evaluate feasibility of our protocol and to collect some preliminary data on the use of Ang 2 in this patient population. As such we plan to enroll approximately 30 patients who have accepted an offer to receive a donor liver. We hope to reach our goal enrollment within 5 months of starting the study.

Cirrhosis Medical Home

To address the health care system's lack of care coordination, the Institute of Medicine and Centers for Medicare and Medicaid Services recommend the development of collaborative care models (CCM) in a wide range of clinical settings. CCMs are intended to provide coordinated, personalized care pragmatically using care coordinators. CCMs have successfully improved care in multiple patient populations, ranging from frail older adults to depression. In contrast, for patients with cirrhosis, there is a paucity of data to support the benefit of CCM in this medically complex and vulnerable population. At Indiana University, researchers have over 20 years of experience in developing, testing, and implementing CCMs successfully for patients living with dementia or depression. Building on these successes, we have customized the CCM to best meet the unique and complex biopsychosocial needs of patients with cirrhosis: the Cirrhosis Medical Home.
