Filter by:This study involves utilizing a noninvasive computer application (Neurofit) that performs oculometric assessment of dynamic visual processing in patients with liver cirrhosis to see if the presence of advance liver disease influences eye movement metrics.
This is a global study to compare the effects of AXA1665, an orally active mixture of amino acids, compared to placebo, on cognitive and physical function, as well as the safety and tolerability of AXA1665.
Individuals with cirrhosis are likely to develop overt hepatic encephalopathy for which diagnostic modalities and treatment options are limited. The purpose of this study is to determine if individuals with cirrhosis who experience hepatic encephalopathy would benefit from investigational microbiota restoration therapy due to their inherent cognitive alterations. Analysis for a correlation between changes in microbiome composition and specific blood biomarkers could allow for earlier diagnosis of HE which could then be treated earlier and with novel treatments.
A total of 46 patients diagnosed with liver cirrhosis will be recruited. All patients will be evaluated with five psychometric tests and critical flicker frequency to diagnosis minimal hepatic encephalopathy (MHE). A breath test sample will be performed in all patients with MHE with 10 g of lactulose to establish the diagnosis of small intestinal bacterial overgrowth (SIBO). Patients diagnosed with EHM and SIBO will be randomized to receive per day 1200 mg of rifaximin (group A) or placebo (group B) for 2 weeks. A complete medical history, nutritional assessment, biochemical studies, and evaluation of quality of life will be performed in all patients included in the study. Besides the initial visit, patients will receive subsequent care 2, 4, 8, 12, and 24 weeks after the beginning of the study.
A total of 80 patients diagnosed with liver cirrhosis and minimal hepatic encephalopathy will be recruited. They will be randomized to receive high protein diet ( n = 40) and a normal protein diet ( n = 40 ) during one month. Randomization will be conducted by an external monitor and will keep the secret codes until the end of the study. All patients will be provided with structured menus and two snacks a day as an amaranth protein supplement. The supplement will content the same amount of fiber but the protein content will vary depending on the group to which the patient is assigned.
Transjugular intrahepatic portosystemic shunt (TIPS) is the first-line therapy for patients with cirrhosis and refractory ascites. However, mental changes known as hepatic encephalopathy (HE) frequently occur after TIPS. There is no effective method to predict HE after TIPS. Oral glutamine challenge (OGC) and psychometric tests have been used to assess the risk for HE, but never in patients undergoing TIPS. Severe muscle loss may also predispose patients to HE. The aim of the present study is to assess if both the OGC and psychometric tests can accurately predict the development of overt HE after TIPS. Patients will be studied before TIPS and followed after TIPS for the development of HE. The role of muscle loss in favoring HE, as well as is possible reversibility after TIPS will also be investigated.
100 ambulatory cirrhotic patients attending a liver transplant clinic will undergo a comprehensive clinical evaluation for severity of liver disease, anemia, depression, and fatigue. Fatigue will be assessed with the FIS and sub-maximal exercise capacity with the 6-minute walk test (6MWT), a standardized exercise test that measures the distance that a patient is capable of walking in 6 minutes (6MWD). Depression will be assessed by using three well-known questionnaires. The SF-36, Beck's Depression Inventory (BDI-II), EQ-5D, and the Psychological General Well-Being Index (PGWBI). Univariate analysis will be performed to select the factors that potentially are associated with the scores as indicated by a P value <.20; the selected factors will then be entered in a stepwise regression to create a multivariate model giving the combination of factors that are significantly associated with the measure of fatigue and depression. Hemoglobin (Hb) levels will then be added to the model in order to test its significance while controlling for the other factors.
This is a prospective study designed to examine the role of bacterial overgrowth and delayed intestinal transit and the effect of Rifaximin with hepatic encephalopathy (HE). This study is divided into Phase A and Phase B. The purpose of Phase A is to test patients with cirrhosis to determine if they have bacterial overgrowth which may lead to slow intestinal transit and hepatic encephalopathy. The purpose of Phase B is to investigate whether the improvement found in patients with hepatic encephalopathy taking Rifaximin is also related to decreased bacterial overgrowth. Subjects' mental capacity will be assessed at each visit via interview, brief mental status, questionnaires and psychometric evaluation. Any subject who appears to have lost capacity to continue participation, as evidenced by HE grade 2 or higher, a lack of attentiveness, concentration, or understanding of evaluation, will be discontinued from the study. Female subjects of childbearing potential will be asked to comply with the use of contraception during the Phase B study period as well as throughout the time they remain on study drug.
The purpose of the study is to evaluate the safety of Rifaximin or placebo in subjects with severe hepatic impairment and Hepatic Encephalopathy.
The purpose of this study is to determine whether taking Rifaximin (Xifaxan) in conjunction with the use of nutritional concepts is effective in improving morbidity and quality of life in cirrhotic patients suffering from hepatic encephalopathy (HE).
