Granulocyte transfusions in children using filter-collected cells.

Twenty-three children with various stages and morphologic types of leukemia were treated with multiple granulocyte transfusions obtained by filtration leukapheresis when neutropenia-associated infection appeared unresponsive to antibiotics. All children meeting the above qualifications were given granulocyte transfusions during this time period. Twenty-one of 23 became afebrile during or shortly after the transfusions; one died with disseminated Herpes simplex; and one became well enough to be discharged, although he was never free of fever. Frequent mild to moderate fever and chills were noted. One child developed a severe pulmonary reaction followed by resolution of pneumonia. Filtration leukapheresis is a useful adjunct in controlling severe infections in neutropenic children.
