Case report: A ten-month-old boy presented with a severe auto-immune hemolytic anemia. Direct antiglobin test was positive only for IgA class autoantibodies. He recovered with a high dose corticosteroid treatment.
Conclusion: IgA class autoantibodies should be searched for in the case of a high suspicion of auto-immune hemolytic anemia with negative direct antiglobin test for IgG and complement. Corticosteroid treatment is most often successful.
