The primary objective of the Pediatric Acute Liver Failure (PALF) study is to collect, maintain, analyze, and report clinical, epidemiological, and outcome data in children with ALF, including information derived from biospecimens.
Minimal Hepatic Encephalopathy in Hereditary Hemorrhagic Telangiectasian
Hepatic EncephalopathyMinimal Brain DysfunctionHHT or Rendu-Osler-Weber disease is a genetic disease with an autosomal dominant inheritance pattern, characterized by widespread telangiectases that can involve several organs including the intestinal tract and the liver. Liver involvement by HHT is characterized by widespread diffuse liver vascular malformations that give origin to arteriovenous, arterioportal and portovenous shunts. The prevalence of hepatic involvement in HHT can reach 78%. Less commonly, patients may also develop porto-systemic encephalopathy (PSE). However, there are no studies on the possibility that patients with HHT might develop mHE, a highly plausible hypothesis considering the presence of diffuse macroscopic and microscopic porto-systemic shunt in this pathological condition.
A Retrospective, Open-label, Uncontrolled Cohort Study to Assess the Effectiveness and Safety of...
Hepatic EncephalopathyThis is a retrospective study in adult patients with cirrhosis and grade 3 or 4 HE (West Haven Criteria) to evaluate the effectiveness and safety of lactulose retention enema in the treatment of deep grade HE (West Haven Criteria). The study will be conducted retrospectively in a multi center of a multispecialty tertiary care hospital in India, in which lactulose retention enema is the mainstay of management of cirrhotic patients with grade 3 or 4 HE (West Haven criteria). Dosing of lactulose retention enema in this study will be done according to the dosing described for rectal administration of lactulose (India): 300ml of lactulose mixed with 700ml of potable water to be used as a retention enema; the enema is to be retained for 30-60 minutes and repeated every 4-6 hours until the patient is able to take oral medication. This treatment regime is also the standard protocol of management of deep grade HE (West Haven criteria) in the study centers. The standard treatment protocol of deep grade HE (West Haven criteria) of the study centers will also ensure that all known contraindications of lactulose will be respected before administration of lactulose retention enema to the study patients. The retrospective hospital records of the patient population of interest within the past 6 months will be identified, and these records will be used to collect data required for analysis.
HepQuant to Predict Hepatic Encephalopathy After TIPS
Hepatic EncephalopathyCirrhosis1 moreA pilot study to determine if a simple blood test can predict patients at risk for significant episodes of confusion and disorientation that can occur in patients who receive an artificial shunt through the liver to control complications of liver disease.
Secondary Prophylaxis of Hepatic Encephalopathy in Cirrhosis
Hepatic EncephalopathyHepatic encephalopathy (HE), a challenging complication of advanced liver disease, occurs in approximately 30-45% of patients with cirrhosis. The treatment of choice is non-absorbable disaccharides, such as lactulose and lactitol.Probiotics are effective in the treatment of minimal hepatic encephalopathy which precipitates hepatic encephalopathy. The investigators will assess the effects of lactulose and probiotics for the prevention of recurrence of HE (secondary prophylaxis) in patients after the recovery of an episode of overt hepatic encephalopathy.
The Effect of a Large-volume Paracentesis on Fatigue, Sleep, and Quality of Life in Cirrhosis
CirrhosisHepatic Encephalopathy2 moreAscites is the accumulation of fluid within the peritoneal cavity of the abdomen. It is a frequent complication of cirrhosis that is associated with significant morbidity and poor quality of life. Large-volume ascites has been associated with impaired pulmonary function. In a previous study, the presence and severity of ascites were determined to be significant determinants of fatigue. In this study, we will determine whether large-volume ascites contributes to fatigue by assessing the response to drainage of ascites by means of a procedure called large-volume paracentesis. We hypothesize that treatment of ascites with a single large-volume paracentesis leads to decreased fatigue and improved quality of life and that this improvement is associated with improved sleep pattern. 20 patients with cirrhosis with refractory ascites requiring regular drainage of ascites fluid by large-volume paracenteses will be recruited for the study. All patients will undergo a complete clinical and physical examination for liver function, including blood tests. Hepatic encephalopathy, a change in mental status associated with liver dysfunction, will be assessed by obtaining historical data and by means of simple bedside neuropsychological examinations. Study visits will take place on two consecutive days, with each visit lasting approximately 2-3 hours. Immediately prior to a large-volume paracentesis, patients will complete standardized questionnaires for fatigue severity, quality of life, quality of sleep, and a physical assessment of fatigue by means of a 6-minute walk test. Repeat evaluations will be performed 1 day after the procedure. Statistical analysis will then be performed to determine the effect of the paracentesis on the various clinical assessments.
Effect of Music on Attention and Prospective Memory in Hepatic Encephalopathy
CirrhosisHepatic EncephalopathyHepatic encephalopathy (HE) is a potentially reversible, metabolically caused complication of acute or chronic liver diseases such as cirrhosis. Due to the diseased liver's inability to remove toxins such as ammonia, which is produced in the gastrointestinal tract, the ammonia accumulates in the brain and causes forgetfulness, confusion, disorientation, concentration and memory problems, changes in mood, decreased alertness and responsiveness, changes in sleep habits, muscle tremors and stiffness, speech impairments, uncontrollable movements, agitation. This study will examine music as a possible external factor that could contribute to impairment in attention and progressive memory in cirrhotic patients while driving. Sustaining attention is important for learning and remembering new information, for e.g. keeping the car within lane and paying attention to cyclists and pedestrians. Prospective memory is the ability to remember to perform previously intended tasks at the appropriate time or occasion, for instance remembering the correct exit while driving on the highway. Impairment in any of these areas may result in serious consequences for patient with cirrhosis. There is evidence that some subsets of cirrhotic patients have a diminished ability to drive and significantly more motor vehicle crashes and traffic violations. In these patients, listening to music while driving may further jeopardize their driving ability, which in turn may lead to reduced quality of life and increased medical costs (from motor vehicle accidents). This is a cross-sectional study designed to determine if there is any effect of listening to music on attention and prospective memory in patients with cirrhosis. For these purposes, subjects will be asked to come for one study visit, which will last approximately 2 hours. During this visit, subjects will undergo a series of screening procedures (consent, assignment of subject identification number, demographics, medical history, physical examination, vitals, height, weight, and eligibility assessment). If they are found eligible, subjects will undergo several neuropsychological assessments to measure any effect of music on attention and prospective memory. These assessments include including Number Connection Test (NCT), Digit Symbol Test (DST), Cambridge Prospective Memory Test (CAMPROMPT) and Inhibitory Control Test (ICT).
