A 15 month old girl with suspected immune neutropenia was treated with high dose immunoglobulin because of recurrent infections over a period of 9 months. Before therapy her neutrophil counts were below 0.5 G/l. With monthly intravenous immunoglobulin her neutrophils remained above 0.5 G/l with one exception. Even after 9 months the patient responded well to therapy, she did not experience new episodes of infections. We suggest that in case of recurrent infections high dose immunoglobulin therapy should be considered in patients with immune neutropenia before the occurrence of life threatening infections.
