RESUMEN

The patterns of white blood cell parameters and mean peroxidase index (MPXI) changes in recombinant human granulocyte colony-stimulating factor (rhG-CSF) prophylactic patients, receiving myelosuppressive chemotherapy, have been studied in 8 cases, using flow cytochemistry blood autoanalyser (Technicon R H*1). No severe neutropenia (absolute neutrophil count, ANC < 0.50 x 10(9)/L) appeared in 6 rhG-CSF primary prophylactic patients, but severe neutropenia was noticed in 2 rhG-CSF secondary prophylactic patients for a period less than 1 week. In most of the cases the significant increase of neutrophil during leukocytosis occurred within 24 hours after starting rhG-CSF prophylaxis, and decreased within 24 hours after the end of rhG-CSF prophylaxis. There was a small degree of lymphocytosis, monocytosis, and basophilia in some cases. From this study, there were no significant changes of MPXI during rhG-CSF prophylaxis, the neutrophils produced during proliferative response to rhG-CSF possessed normal myeloperoxidase (MPO) activity. We concluded that the information obtained from automated blood cell analyser Technicon R H*1 especially MPXI and ANC, could be very useful for monitoring rhG-CSF prophylactic patients receiving myelosuppressive chemotherapy. The advantages of the MPXI over other methods is its simplification when performed as part of a routine complete blood count (CBC) on an automated hematology instrument, and its ability to measure even severe neutropenic samples.
