title: Severe hemolytic anemia due to auto anti-N.
abstract: Auto anti-N is infrequently encountered and, in most reported cases, does not cause clinical hemolysis. This case reports an auto anti-N associated with severe hemolytic anemia (Hb=2.7 g/dL) in a 6-year-old Caucasian girl with a history of vomiting, fever, and abdominal pain. Upon admission, she was found to have a metabolic acidosis, secondary to her severe anemia, with abnormal liver function tests. As in three other case reports, the autoimmune hemolytic anemia resolved, with disappearance of the auto anti-N, after corticosteroid therapy.
