"Among the patients who had acute liver failure due to antiepileptics, one-year survival was only 27 percent in patients less than 18 years old compared to 75 percent in patients 18 years old or older," the authors report. Interestingly, these patients were least likely to be listed as status 1 and spent the most time waiting for an organ. Also, the warm and cold ischemia times were longest for this group of patients. "The relatively low survival probability persisted after controlling for these variables in multivariate analysis," the authors report. The reasons for the decreased survival in this group could not be elucidated based on the available data.
Examining the different demographic and clinical factors for each patient and donor, the researchers noted that, "elevated serum creatinine, being on life support, and drug-induced acute liver failure due to antiepileptics (at age less than 18) were found to be independent pretransplant predictors of poor survival."
Using the entire study population, the researchers developed a prognostic model which showed strong predictive ability.
An accompanying editorial by Paul B. Watkins of the Institute for Drug Safety at the Hamner Institutes of Health Sciences, Research Triangle, NC and Paul H. Hayashi of the University of North Carolina , commends the authors for adding valuable information about acute liver failure caused by drugs. In particular, "the identification of poorer outcome for children with anti-epileptic drug induced acute liver failure is intriguing and points out the need for more focused research on drug induced liver injury in pediatric populations
