Answer

Idiopathic methemoglobinemia can occur in association with systemic acidosis. This typically occurs in infants younger than 6 months and is usually caused by dehydration and diarrhea. Idiopathic methemoglobinemia is exacerbated by the lower levels of methemoglobin reductase enzyme found in infants (50% of adult levels).
