We illustrate an unusual paediatric case of transient 5-oxoprolinuria presenting during an episode of severe sepsis with concomitant paracetamol use. The 15-month-old patient had an extremely high anion gap metabolic acidosis. The anion gap is the difference in the measured cations (positively charged ions) and the measured anions (negatively charged ions) in serum, plasma, or urine.

A growing number of case reports and case series describe high anion gap metabolic acidosisTypically 5-oxoprolinuria or 5-oxoprolinemia occurs in the setting of inborn genetic errors in glutathione metabolism.Clinicians should first exclude commoner and treatable causes of HAGMA, such as When acidosis is present on blood tests, the first step in determining the cause is determining the anion gap. If the anion gap is high (>12 mEq/L), there are several potential causes. High anion gap metabolic acidosis is a form of metabolic acidosis characterized by a high anion gap Pts receiving high rates of these drugs may develop a hyperosmolar anion- gap metabolic acidosis, due mostly to increased lactate, often accompanied by acute kidney failure. Pyroglutamic aciduria ( 5-oxoprolinuria) is a high anion-gap acidosis caused by dysfunction of the A rare cause of high anion gap acidosis is 5-oxoproline (pyroglutamic acid), an organic acid intermediate of the gamma-glutamyl cycle. Acetaminophen and several other drugs have been implicated in the development of transient 5-oxoprolinemia in adults. The transient 5-oxoprolinuria with normal glutathione concentration appeared to be the only obvious cause of the severe high anion gap metabolic acidosis in this patient.
