Toxic encephalopathy

This study compares two ways of placing a stent in the liver to prevent repeat bleeding from swollen veins in the throat or stomach in people with cirrhosis. The standard method fully expands the stent, while the new method uses a smaller balloon to keep it slightly narrower. The…

This study tests whether two drugs that calm the immune system—high-dose steroids or anti-thymocyte globulin—can help children with sudden, severe liver failure survive without needing a liver transplant. About 163 children aged 1 to 17 will be randomly assigned to receive one of…

This study looks at whether giving a protein called albumin through a vein can help improve thinking and memory in people with liver cirrhosis who have had episodes of confusion (hepatic encephalopathy). The trial will involve 30 participants who will receive both albumin and a p…

This study tests whether adding the blood thinner apixaban to the heart drug carvedilol can prevent complications like bleeding, fluid buildup, and confusion in people with cirrhosis and high blood pressure in the liver. About 220 adults with stable cirrhosis will take either api…

This study tests whether taking capsules of processed donor stool (fecal transplant) can help people with liver cirrhosis avoid serious infections and hospital stays. About 300 adults with alcohol-related or fatty liver cirrhosis will receive either the transplant or a placebo an…

This study tests a new treatment called RTX001 for people with severe liver scarring (cirrhosis) that has led to complications. RTX001 uses the patient's own immune cells, modified in a lab to reduce inflammation and scarring. The trial will enroll 30 adults to check if the thera…

This study tests a technique called 'underdilated stent' during a liver shunt procedure (TIPS) for people with cirrhosis. The goal is to see if using a smaller balloon to place the stent can lower the risk of hepatic encephalopathy (brain confusion) after the procedure, while sti…

This study tests whether taking a protein supplement (Ensure Enlive) in the late evening and early morning can reduce hospital readmissions for people with hepatic encephalopathy, a brain condition caused by liver disease. The trial enrolls 40 adults with cirrhosis who have been …

This pilot study tests a new cognitive test using building blocks to quickly screen for minimal hepatic encephalopathy (MHE), a subtle brain complication in people with liver disease. Researchers will compare the test's accuracy against standard methods in 100 adults with liver f…

This study tests whether a structured exercise program, with or without nutritional advice, can lower the risk and severity of neurotoxicity (brain-related side effects) caused by CAR-T cell therapy in adults with blood cancers. One hundred participants will be randomly assigned …

This study is testing whether tiny particles in the blood, called extracellular vesicles, can predict nerve damage caused by chemotherapy. Researchers will follow 120 adults with various cancers who are receiving specific chemo drugs. Participants give blood samples and answer qu…

This study looks at how nerves are affected in people who develop nerve damage from the chemotherapy drug cisplatin. Researchers will use a special test to measure nerve activity and compare it to normal nerves. The goal is to better understand this side effect and find early war…

This study tests whether a non-invasive handheld device that measures pupil size and reactivity can predict neurological side effects in patients receiving CAR-T cell therapy for lymphoma. Researchers will monitor 100 adults before and after treatment to see if pupil changes sign…

This study is creating and testing a new questionnaire called LiCCoS for adults with liver cirrhosis. The goal is to help identify common thinking problems like forgetfulness or trouble focusing, which are often missed. About 230 participants will fill out the questionnaire and t…

This pilot study at Mayo Clinic is testing whether a dietary supplement called resistant potato starch can change gut bacteria in people with cirrhosis who have had episodes of confusion (hepatic encephalopathy). Eleven participants will take 20 grams of potato starch twice daily…

This study follows 940 adult cancer patients starting immunotherapy to understand why some develop immune-related side effects, especially those affecting the brain and nerves. Researchers will collect blood samples and health data over time to find early warning signs. The goal …

This study compares two common anesthesia methods—inhaled gases (sevoflurane or desflurane) versus intravenous propofol—in 84 adults having brain tumor surgery. Researchers will measure brain oxygen levels, swelling, and thinking skills after surgery to see which approach better …

This study follows 10,000 people with advanced chronic liver disease at Vienna General Hospital. Researchers will track their health over time, collect blood, urine, and tissue samples, and record complications like bleeding or liver failure. The goal is to better understand how …
