Hemolytic disease of the newborn due to anti-Dib.

A case of moderately severe erythroblastosis fetalis due to anti-Dib is reported. The mother was a Mexican-Indian woman who had received three units of blood following the delivery of a normal infant three years previously. The affected infant required phototherapy and two exchange transfusions. Although the units were incompatible, the infant tolerated the procedures well and appeared normal when last seen at the age of 2 1/2 months. This case brings to 11 the total number of instances of anti-Dib reported.
