In homocystinuria due to cystathionine beta synthase (CBS) deficiency or classical homocystinuria, decreased blood cysteine levels are observed. Cysteine is essential for the synthesis of molecules such as glutathione and taurine. Main functions of glutathione are to detoxify drugs and to scavenge reactive oxygen species. N-acetylcysteine is a commercially available drug chemically similar to cysteine. In CBS deficient animal models, N-acetylcysteine supplementation improves cy...
The purpose of this study is determine if oral N-acetylcysteine is effective in lowering homocysteine in individuals with homocystinuria.
OBJECTIVES: I. Determine the safety and efficacy of a short course (72 hours) of intravenous acetylcysteine in patients with acute liver failure for whom no antidote or specific treatment is available.
We have completed patient enrollment in the the double blind, randomized, placebo-controlled trial of intravenous (IV) N-acetylcysteine (NAC) vs. placebo for the treatment of non-acetaminophen ALF. The purpose of this study is to examine the safety and efficacy of intravenous NAC in children with ALF for whom no antidote or other specific treatment is available. Inclusion in the NAC Study required enrollment in the Pediatric Acute Liver Failure (PALF) Study Registry.

Acetaminophen is commonly used to treat fever or pain. Your body clears acetaminophen by processing it in the liver. During the processing, some of the acetaminophen may bind to proteins in the liver. The protein-acetaminophen product is called an "adduct". After a large acetaminophen overdose, the liver has to process a lot of acetaminophen, so large amounts of adducts are formed. However, we have found that lower levels may be formed even when people take recommended doses. T...
N-acetylcysteine is an inexpensive agent with a benign side effect profile with preliminary studies in humans suggesting efficacy for the treatment of cocaine dependence. N-acetylcysteine has been used in clinical medicine for nearly three decades to treat chronic lung conditions, acetaminophen overdose, and experimentally to treat cocaine dependence. It is generally safe and well tolerated. The present pilot study seeks to explore safety and tolerability, ad lib smoking, vis...
This proposed study is a multi-center open label study to determine if N-acetylcysteine has any survival benefits in patients with ALF.
The primary purpose of this study is determine if a new formulation of Acetadote is at least as effective as the current formulation in the prevention and treatment of acetaminophen overdose related liver injury.
OBJECTIVES: I. Determine basal and postmethionine plasma homocysteine in patients with premature vascular disease, cystathionine beta-synthase (CBS) or methylenetitrahydrofolate reductase (MTHFR) deficiency, and in obligate heterozygotes for CBS or MTHFR. II. Determine whole-body homocysteine metabolic rates with isotopically-labeled methionine.
It is widely believed that people who abuse alcohol can sustain a liver injury after taking doses of acetaminophen just above the recommended maximum dose. This study is designed to look at the interaction between acetaminophen, liver injury and alcohol abuse. Subjects will undergo baseline tests to ensure that they do not have liver damage at the time of enrollment. Each subject will be randomly assigned to receive either a therapeutic dose of acetaminophen or a placebo three...
The purpose of the study is to characterize the clinical course of Cystathionine Beta-synthase Deficiency Homocystinuria (CBSDH) in pediatric and adult patients under current clinical management practices
The objective of this study is to determine whether acetaminophen (APAP), N-acetylcysteine (NAC), and APAP in combination with NAC will inhibit lipid peroxidation in aneurysmal subarachnoid hemorrhage (aSAH), utilizing F2-IsoPs as biomarkers for lipid peroxidation.
our practice for the past 10 years we have noticed a transitional impairment of liver function (elevated liver enzymes, total and direct bilirubin, and elevated serum lactate levels) following donors' liver resection. Several drugs have been investigation on liver regeneration , proven benefit of N-Acetylcysteine (NAC) on rats with steatohpatitis
The study objective was to evaluate the safety of ten consecutive days of therapeutic acetaminophen dosing in moderate alcohol consumers. The main outcome was liver injury (measured by an increase in mean serum ALT or AST levels). Patients were randomly assigned to 10 days of acetaminophen or placebo. Blood tests were measured at baseline, day 4 and day 11 to look for injury. We hypothesized that there would be no difference in liver enzymes between the two groups.
N-acetylcysteine (NAC) is used to treat Tylenol toxicity. NAC is a rich source of the sulfhydryl group (SH) which is important for replenishing the body's glutathione stores. Glutathione acts as a free radical scavenger, to decrease the damage that would be caused by those toxic radicals. Patients who undergo orthotopic liver transplantation (OLT) have a high incidence of post-operative renal dysfunction. The most common etiology of post-operative renal dysfunction is related t...
Tuberculosis is one of the major health problems in developing countries. Isoniazid, rifampin and pyrazinamide, the first line drugs used for tuberculosis chemotherapy, are associated with hepatotoxicity. The rate of hepatotoxicity has been reported to be much higher in developing countries compared to that in advanced countries with a similar dose schedule. Oxidative stress has proposed as one of the mechanisms responsible for anti-tuberculosis drugs induced hepatic injury. T...
N-acetylcysteine is a medication that has most commonly been used in the past to prevent liver damage after an acetaminophen overdose. N-acetylcysteine has also been used in patients with pre-existing kidney damage to prevent further kidney damage resulting from dye that is used in tests such as angiograms (dye studies). This study hopes to prove that this medication may also help to protect kidneys from the damage caused by the heart-lung machine during cardiac surgery. This d...
This study evaluates the use of N-acetylcysteine in the treatment of alcohol and cocaine use disorders. Alcohol users will be split in two groups, one will receive the active N-acetylcysteine and the other placebo. The same division will occur with cocaine users. The effects of N-acetylcysteine in adherence, abstinence, psychiatric symptoms and stress biomarkers will be evaluated.
The aim of this research project is to compare the effect of an aerobic exercise session in two different populations. Sampling biological material and collecting health-related personal data entails minimal risks and burdens. Participants will be asked to perform 30 minutes of an aerobic exercise on an ergocycle at a fixed power output to correspond to a moderate intensity for a sedentary population.
Although acetaminophen is the most commonly used nonprescription drug in the USA, little is known regarding the influence of genes and race/ethnicity on acetaminophen disposition. The investigators long-term goal is to understand the causes of differences in acetaminophen disposition between people that are the result of genetic variation and ethnicity and may predispose individuals to a higher risk of acetaminophen hepatotoxicity. The aim of this particular study is to measur...
The objective of this observational study is to assess improvement of quality of life in the patients who are administered Tramadol 37.5mg/Acetaminophen 325mg tablets for 10~14 weeks according to the investigator's discretion in clinical practice.
The main objective of this study is to investigate the effect of Prometheus liver support dialysis on intracranial pressure, cerebral metabolism and circulation in patients with acute liver failure.
There is limited research on the clinical outcome differences between intravenous (IV) acetaminophen versus oral (PO) acetaminophen. With the costs of intravenous acetaminophen sometimes being almost 100 times the cost of PO acetaminophen, it is not only important fiscally but also clinically to differentiate the benefits of IV vs PO acetaminophen. The proposed research study is to determine the clinical advantages of IV vs PO acetaminophen during the post-operative recovery ti...
