A purpose of this protocol is to is to compare the metabolites of the toxic bioactivating pathway after acetaminophen alone or acetaminophen followed by Propylene Glycol (PG) and to determine if it prevents the formation of the toxic metabolites of acetaminophen.
This study is a non-intervention, clinical study to test "research use only" APAP protein adducts dipsticks in human blood samples. The study will be conducted in two phases. In phase 1, the research use only dipsticks and dipstick testing components will be tested for feasibility in the emergency department at UAMS. Patients will be enrolled that are having an acetaminophen level obtained as part of their medical evaluation. In phase 2, the research use only dipsticks will be tested in centers that participate in the Acute Liver Failure Study Group (ALFSG), a clinical research network funded by the National Institutes of Diabetes, Digestive and Kidney Diseases (NIDDK). Subjects participating in the clinical registry of the ALFSG will be approached for enrollment. These patients all have the diagnosis of acute liver failure or acute liver injury from a variety of etiologies, including APAP. A single blood sample will be obtained and will be aliquoted for 1) testing by the dipstick and 2) testing by high performance liquid chromatography with electrochemical detection (HPLC-EC) analysis for APAP protein adducts. APAP levels will also be determined from the second aliquot of blood. In both Phase 1 and Phase 2, the dipsticks will be read manually and by dipstick readers by independent testers that are not directly involved in the clinical care of the patients. The results of the two dipstick readings will be recorded, will remain confidential and will not be used in the diagnosis or management of the patient. The results of the dipsticks and HPLC-EC assays will be compared to the final patient diagnoses.
Retrospective chart review of patients who receive N-acetylcysteine for Acetaminophen(APAP) toxicity to assess length of oral vs. IV treatment and the effect of a Clinical Pharmacology and Toxicology division in the management of APAP ingestions.
This study is a non-intervention, multicenter study to address biomarkers of acetaminophen toxicity in children. Specifically, the study will examine acetaminophen (APAP) protein adducts and markers of liver injury in the blood samples of hospitalized children and adolescents who are receiving standard doses of acetaminophen, and children and adolescents who are status post acetaminophen overdose. Ultimately, the data generated from this study will be used to establish second generation biomarkers of acetaminophen toxicity, based on specific adduct proteins, which can be used in future risk assessment studies of children receiving acetaminophen.
