Case Reports5-oxoproline-induced anion gap metabolic acidosis after an acute acetaminophen overdose.
Metabolic acidosis after acute acetaminophen overdose is typically attributed to either transient lactic acidosis without evidence of hepatic injury or hepatic failure. High levels of the organic acid 5-oxoprolinuria are usually reported in patients with predisposing conditions, such as sepsis, who are treated in a subacute or chronic fashion with acetaminophen. ⋯ Urinalysis revealed elevated levels of 5-oxoproline, suggesting that the patient's acute acetaminophen overdose was associated with marked anion gap metabolic acidosis due solely to 5-oxoproline without hepatic complications. The acidosis fully resolved with N-acetylcysteine treatment and supportive care including hydration.
