title: Autoimmune hemolytic anemia associated with IgG auto anti-N.
abstract: A second case of autoimmune hemolytic anemia mediated by an IgG auto Anti-N is described. The patient's red blood cells were sensitized with both IgG and complement. The serum antibody was not inactivated by 2-mercaptoethanol treatment, and reacted by indirect antiglobulin test at 37 C with monospecific anti-IgG. The IgG antibody eluted from the red blood cells and in the serum showed anti-N specificity. The patient was thought to have systemic lupus erythematosus. Following steroid therapy, the hemolytic anemia resolved with disappearance of the anti-N.
