L-ornithine L-aspartate in Overt Hepatic Encephalopathy

Cirrhosis of LiverHepatic Encephalopathy

Hepatic encephalopathy (HE) is a potentially reversible functional disorder of the brain with neurological and psychiatric symptoms. HE occurs in up to 70% of patients with cirrhosis at some time during the course of disease. The chief neurotoxin implicated in the development of HE is ammonia. An important aim of treatment of HE is the reduction of the ammonia in the body by lowering the amount of ammonia produced and increasing its detoxification. Enteric production of ammonia can be decreased by non-absorbable disaccharides such as lactulose and antibiotics such as rifaximin. L-ornithine- L-aspartate (LOLA), the salt of the natural amino acids ornithine and aspartate acts through the mechanism of substrate activation to detoxify ammonia. In clinical trials, LOLA has shown a statistically significant effect with respect to reduction in HE grade, reduction of blood ammonia concentration and positive effects on psychomotor function in patients of cirrhosis with minimal HE and overt chronic Grade I HE, as compared to placebo. However, there is lack of data on the efficacy of LOLA in patients with overt acute hepatic encephalopathy which is one of the major causes of hospital admissions and resource utilization in decompensated cirrhotics. Each admission for HE causes a major financial loss to the family and financial burden on the society. Any drug which decreases the hospital stay by rapidly improving HE, will clearly lead to decreased hospital costs to the individual and the society as a whole. Hence, such a trial is a national priority. The investigators hypothesize that LOLA, if added to the standard treatment of overt acute HE (i.e lactulose), may lead to a faster recovery and decrease in hospital stay of these patients. In this prospective, randomized, placebo controlled trial, the investigators aim to evaluate the efficacy of intravenous L-ornithine, L-aspartate in reversal of overt acute hepatic encephalopathy in patients with liver cirrhosis.

Effects of Aerobic Training on Exercise Capacity in Patients With Cirrhosis

Cirrhosis

Cirrhosis is associated with a reduction in muscle mass and exercise capacity. This has an impact or morbidity and mortality. Regular aerobic exercise training is a proven effective therapy to improve exercise capacity in healthy and clinical populations. the effect of this training has not yet been evaluated in cirrhosis. The safety of this intervention also requires further study. Using a randomized controlled design, the investigators aim to conduct a pilot study evaluating the safety and efficacy of eight weeks of aerobic exercise training on aerobic capacity.

Role of Midodrine and Tolvaptan in Patients With Cirrhosis With Refractory or Recurrent Ascites...

CirrhosisRefractory/Recurrent Ascites

The development of ascites in the natural history of cirrhosis heralds a worsening of the prognosis to 50% survival at 2 years, and this deteriorates to 30-50% at 1 year when the ascites becomes refractory to medical therapy. Hemodynamic alterations and their relation to neurohumoral systems are essential in pathophysiology of ascites formation. The theory that best explain the ascites formation and sodium retention in cirrhotics is portal hypertension leading to splanchnic arterial vasodilatation leading to underfilling of arterial circulation which is sensed by the arterial and the cardiopulmonary receptors leading to sympathetic nervous system activation and activation of the anti-natriuretic factors (RAAS and arginine vasopressin), resulting in sodium and water retention. The therapeutic options available for patients with refractory ascites are serial therapeutic paracentesis, liver transplantation and transjugular intrahepatic portosystemic shunts.Vasopressin V2 receptor antagonists antagonize the antidiuretic effects of vasopressin at the V2 receptor located in the renal collecting duct, they increase free water clearance, and thus may be helpful in mobilizing excess water in conditions associated with water retention including cirrhosis. The use of V2 receptor antagonists in cirrhosis with ascites has been shown to be safe and efficacious. Midodrine, an alpha adreno receptor agonist by causing splanchnic vasoconstriction has been used in hepatorenal syndrome (HRS) and for control of ascites in patients with refractory or recurrent ascites. It is possible that vasoconstrictors and aquaretics (V2 receptor antagonists) by acting at different sites in combination may reverse some of the pathogenic events that results in refractory or recurrent ascites.There are no reports on the use of combination of midodrine and tolvaptan in the patients with cirrhosis with ascites. Therefore, we plan to study the role of midodrine, tolvaptan and their combination on systemic hemodynamics, renal functions and control of ascites in patients with cirrhosis and refractory or recurrent ascites.

Effects of Home Based Exercise Therapy in Early Cirrhosis

Cirrhosis

Individuals with Cirrhosis have been shown to have a low aerobic capacity. While supervised exercise training has been shown to be an effective intervention to remedy this, there is currently no data on home based exercise interventions in this population. This study will evaluate the effects of a home based exercise program on the aerobic capacity of enrolled early stage liver cirrhosis patients, as well as changes in quality of life, thigh muscle thickness, and thigh muscle oxygen consumption.

Influence of Probiotics on Infections in Cirrhosis

Liver Cirrhosis

Liver cirrhosis is the 10th most common cause of death in the western world. Infection is the most common precipitant of deterioration of liver function in cirrhosis. Endotoxin, derived from gram-negative organisms in the gut, can enter the circulation due to increased gut permeability and contributes to neutrophil dysfunction, infection risk and mortality in alcoholic cirrhotics. As probiotics decrease gram-negative organisms in the gut and/or decrease gut permeability, the investigators hypothesize that probiotic treatment would restore neutrophil function and prevent infection in alcoholic cirrhosis. The investigators hypothesize that administration of a probiotic mixture in patients with liver cirrhosis will improve innate immune function through alteration of the gut bacterial flora and gut barrier integrity. The aim of this randomised, double-blinded placebo-controlled study is to assess whether food supplementation with probiotic mixture improves neutrophil phagocytic capacity in patients with cirrhosis and decreases the incidence of significant infections. 92 patients with alcoholic cirrhosis will be included according to a sample size calculation from preliminary data. Patients will be randomized in two groups: Group 1 receives a probiotic mixture Group 2 receives a similar looking and tasting placebo without bacteria. The recruited patients will be treated for 6 months. Besides routine clinical and laboratory assessments, neutrophil function, toll-like receptor expression, endotoxin levels, bacterial DNA, cytokine levels, albumin oxidation, gut permeability and analysis of gut microflora will be performed. Furthermore nutritional status and quality of life will be assessed. Primary endpoints will be neutrophil phagocytosis. Secondary endpoints will be significant infection, neutrophil oxidative burst, neutrophil toll-like receptor expression, endotoxin levels, bacterial DNA; cytokine levels, albumin oxidation, gut barrier function and bacterial flora, nutritional status and quality of life. If our hypothesis holds true, probiotics will provide an easily applicable and cost effective method to improve immune function and to prevent infection in liver cirrhosis. It is possible that this can improve survival of patients with liver cirrhosis.

Vitamin E Supplement in Patients With Cirrhosis and Acanthocytosis

Cirrhosis

Acanthocytes, also termed spur cell, are large erythrocytes covered with spike-like projections which are associated with severe hemolytic anemia. In advanced cirrhosis, acanthocytes may account for 20 to 30% of red blood cells. Up to 70% of cirrhotic patients display anemia and hemoglobin level may fall to below 5 gr/L in spur cell anemia. The true incidence of spur cells in cirrhosis is not known precisely but may avoisinate 45%, typically in patients with advanced cirrhosis.The presence of spur cells usually predicts lower survival rates. Vitamin E is an antioxidant compound that is a component of biological membrane that helps to maintain integrity of lipid bilayers. Vitamin E deficiency leads to erythrocyte hemolysis, which is improved by supplemental vitamin E. This study is an open label single arm phase II study in cirrhotic patients treated for 4 weeks with Tocofersolan (Vedrop), a water-soluble derivative of alpha-tocopherol, and thus an orally bio-available source of vitamin E. The aim of this study is to determine the effect of tocofersolan on red blood cell membranes lipid composition in adult patients with cirrhosis and vitamin E deficiency. Secondary endpoints are the effects of tocofersolan on anemia, hemolysis and acanthocytosis; on lipid peroxidation and oxidative stress; the safety of a 4 week treatment of 700 mg/day.
