Auto-immune hemolytic anemia associated with IgA is uncommon.
Case report. - A ten-month-old boy presented with a severe auto-immune hemo
lytic anemia. Direct antiglobin test was positive only for IgA class autoan
tibodies. He recovered with a high dose corticosteroid treatment.
Conclusion. - IgA class autoantibodies should be searched for in the case o
f a high suspicion of auto-immune hemolytic anemia with negative direct ant
iglobin test for IgG and complement. Corticosteroid treatment is most often
successful. (C) 2001 Editions scientifiques et medicales Elsevier SAS.
