Filter by:This research study is being done to learn what effect 7 days of treatment with the Selective Cytopheretic Device (SCD) will have on these white blood cells in the bloodstream of patients with hepatorenal syndrome and to learn whether it has any effect on the blood circulation and kidney function.
Hepatorenal syndrome is a functional renal impairment occurring in cirrhotic patients . It develops secondary to splanchnic arterial vasodilatation which decreases the effective blood volume, activate the renin-angiotensin-aldosterone system, and stimulate of sympathetic nervous system.This study aims to compare the efficacy of nor-epinephrine versus midodrine/ octreotide, together with intravenous albumin on renal functions of patients with hepatorenal acute kidney injury.
Hepatorenal syndrome-acute kidney injury (HRS-AKI), a potentially reversible renal failure, is a serious, rapidly progressing, often fatal, complication of decompensated cirrhosis. Terlipressin is a synthetic vasopressin analogue that acts as a systemic vasoconstrictor via the vascular vasopressin V1 receptors. In HRS-AKI patients the strong V1 receptor-mediated vasoconstrictor activity of terlipressin, particularly in the splanchnic area, increases effective intravascular volume and mean arterial pressure (MAP), ameliorates renin-angiotensin-aldosterone system and sympathetic nervous system hyperactivity, and improves renal blood flow. The INFUSE trial will evaluate the use of continuous terlipressin infusion in patients on the liver transplant waiting list with HRS-AKI.
Evaluation of non-invasive prognostic parameters in patients developing ACLF and renal failure in patients receiving and not receiving transjugular intrahepatic portosystemic shunt (TIPS). Patients are cared according to the local standardized follow up program. Clinical and laboratory data from standard patient care are evaluated for potential prognostic value.
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.
Hepatorenal syndrome is a life-threatening medical condition and a serious complication of advanced liver scarring (cirrhosis). It consists of a deterioration of the function of the kidneys caused by a severe alteration in the circulation (blood flow to the kidneys) due to liver cirrhosis. Only around half of the patients respond to treatment which consists of intravenous medication. Moreover, the adrenal glands, which are located on the kidneys, also suffer an alteration in the blood flow leading to deterioration in their function as well. Thus, these patients produced less cortisol than needed; this situation is called "relative adrenal insufficiency". Cortisol is an important hormone necessary in extreme situations such as severe diseases. This is a study which will assess the relationship between the presence of adrenal dysfunction and failure to treatment in patients with hepatorenal syndrome.
Hepatorenal syndrome (HRS) is a disease in which patients with cirrhosis (end stage liver failure) develop secondary kidney injury and failure. The current treatment available in the United States is a combination of octreotide and midodrine, which are meant to decrease the release of those hormones and raise the blood pressure, respectively, which would increase blood flow to the kidneys. Angiotensin 2 (Ang2) is a new vasopressor drug that was approved by the FDA in December 2017 for patients with low blood pressure and has been shown to have similar effects to octreotide and midodrine. This study will investigate whether Ang2 reverses HRS among patients admitted to the intensive care unit (ICU) at Ronald Reagan Medical Center. Our study population will be patients with HRS who are already or will be admitted to the ICU. HRS will be defined by new internationally accepted guidelines published by the International Club of Ascites. All patients who are consented will undergo an Ang2 response trial, where low-dose Ang2 will be administered for 4 hours to see how the patients respond. This will help us characterize the nature of the patients' kidney failure for later analysis. Patients will then be randomized into the control group or the study group. Patients in the control group will receive octreotide (a subcutaneous injection) and midodrine (an oral drug). Patients in the study group will continue receiving intravenous infusion of Ang2. Patients in both groups will also receive albumin, a protein found commonly in human blood. Treatment will continue in both groups for four days, until complete reversal of HRS, dialysis, or death. Our primary outcome will be rate of reversal of HRS, defined as improvement in kidney function.
Hepatorenal syndrome (HRS) is defined as a functional renal failure in a patient with chronic liver disease, or liver cirrhosis.The splanchnic circulation undergoes severe vasodilation, as a result of portal hypertension, causing an underfilling of systemic arteries.This results in intense renal vasoconstriction and functional renal failure. The best treatment options for HRS I would be a drug which has renal vasodilator property and additional splanchnic vasoconstriction. An increase in circulating blood volume would be of additional benefit. Currently Terlipressin is considered superior to other drugs in the management of HRS I. Other drugs in use are Noradrenaline and Midodrine. Albumin is added to these drugs in order to expand plasma volume. Terlipressin, a Vasopressin analog, has agonistic activity at V1 receptors. Noradrenaline acts as an agonist at α-adrenergic receptors with mild β-agonistic activity. The two major drugs used in the management of HRS act at different receptors and have completely varied mechanisms of action. Thus, a combination therapy would improve the rate of response considerably. There have been multiple studies, measuring the efficacy, safety and dosing of both drugs, but none combining both Terlipressin and Noradrenaline. Hence our study would be a pioneer in formulating a new and possibly more efficacious treatment protocol for patients of Type I HRS, in whom the treatment options are otherwise very limited. If successful, this would open new horizons of therapy for Terlipressin refractory HRS, which, otherwise is an ominous condition.
The aim of this study is to investigate i) whether two biomarkers (urine NAG, urinary cystatin C) could be predictive factor in patient with liver cirrhosis, , and ii) whether these biomarkers can predict response of terlipressin.
Heptorenal syndrome (HRS) is divided into two types. A non-acute kidney injury (NAKI-HRS), which is predominantly related to end-stage disease and a more acute kidney injury (HRS-AKI). HRS-AKI is potentially reversible and develops subsequent to aggravation of a systemic circulatory vasodilatation, that triggers renal vasoconstriction and deteriorates renal perfusion and function. The albumin and terlipressin response is evaluated clinically, routinely for a week and reduces mortality with 23% compared to no treatment. Only 40-50% of the patients with HRS-AKI respond to the treatment with terlipressin. The treatment of hepatorenal syndrome (HRS-AKI) is aimed at improving blood flow to the kidneys. Flow changes associated to development of HRS have only sparsely been studied and not previously by MR technique and no previous studies have evaluated changes in flow induced by terlipressin. It has been hypothesized that development of HRS is associated to a deterioration in heart function with development of cardiomyopathy, which together with renal vasoconstriction leads to renal failure. Simultaneous MR-assessments of cardiac function and flows (especially the renal flow) in HRS-AKI have not previously been performed. The aim of the project is to develop new, fast and non-invasive methods to evaluate hemodynamic changes and individual pharmacological terlipressin response in patients with acute hepatorenal syndrome (type HRS-AKI) We expect a higher increase in renal blood flow in terlipressin-responders compared to terlipressin-non-responders and non-responders will generally have a lower basic renal flow and a decreased cardiac output. Study design and patients The study design is experimental and includes 30 cirrhotic patients with HRS-AKI. Patients with HRS-AKI are MR scanned before and 17 minutes after their first dose of terlipressin. ECHO is performed before first dose of Terlipressin and is repeated after one of the first doses of terlipressin. Clinically efficacy is defined in accordance to international guidelines at day-7 and 90 days mortality is registered. The screening period and treatments follow international and national guidelines for acute renal failure in patients with cirrhosis.
