BACKGROUND
Some cases of paracetamol-induced acute hepatic failure may require liver transplantation but the present shortage of graft urges the search for an alternate therapeutic approach.
METHODS
A 17 year-old girl was admitted for sleepingness and vomiting after about 15 hours of voluntary but denied absorption of paracetamol. Plasma paracetamol concentration was 120 mg/l; factors VII+X level were 55% and factor V 106%. The patient was given IV N-acetylcysteine, 150 mg/kg/30 min, then 50 mg/kg/4 hours. Further decrease in facteur VII level led to pursue administration of N-acetylcysteine (total dose: 350 mg/kg/2 hours). While indication of liver transplantation was considered, clinical and laboratory findings definitely improved.
CONCLUSIONS
N-acetylcysteine may be effective even if administered late. Repeated determination of factor VII could be a good means for managing such a severe condition.
