Autoimmune hemolytic anemia with warm antibodies in children: retrospective analysis of 51 cases.

In this paper, research based on 51 children with a positive antiglobulin test is presented. Eighteen of the children had acute anemia and 33 had chronic anemia. Two clinical patterns were distinguished: an acute transient type and a prolonged chronic type. Corticosteroid therapy was effective in all acute cases but its results were variable in the chronic cases. The acute form was more frequent in young children, while chronic autoimmune hemolytic anemia (AIHA) occurred mainly among children at puberty. In the chronic form of the disease, it was sometimes necessary to add immunosuppressive drugs and in two cases to perform a splenectomy.
