title: Clinical experience with the use of rhG-CSF in secondary autoimmune neutropenia.
abstract: This paper outlines the impact of granulocyte-colony stimulating factor (G-CSF) used as a single modality therapy in 17 patients with secondary autoimmune neutropenia (S-AIN) who had been treated a multiple number of times previously. Fifteen of these patients had demonstrable antineutrophil antibodies and two had cellular S-AIN with haemopoietic inhibitory T-cells present in the marrow. Prior to treatment, all had had problems with infection. All patients responded within 7 days of commencement of treatment. Provided G-CSF neutrophil counts were maintained above 1 x 109/l, no further infections occurred. This was achievable by using G-CSF administered as infrequently as once every 8 days. Eight of the 17 patients remained on G-CSF, although five switched to the glycosylated form because of side-effects. None have developed osteoporosis despite 47.29 patient years of total experience with G-CSF. In conclusion both glycosylated and nonglycosylated G-CSF can be used effectively in treating AIN on a long-term basis.
