[Severe autoimmune immunoglobulin A hemolytic anemia in a 10-month-old infant]. / Anémie hémolytique auto-immune sévère à immunoglobulines A chez un nourrisson de dix mois.

ABSTRACT

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.
