Medication Summary
Select antibiotics for infections according to the same principles and standards of care as for other patients. Prophylactic antibiotics may be considered but are required infrequently since the advent of granulocyte colony-stimulating factor (G-CSF) in 1987. Staphylococci and streptococci are the most common causes of infections. Frequent or long-term antibiotic use may result in infections from resistant bacteria, anaerobic bacteria, yeast, fungi, and parasites.
G-CSF requires long-term daily administration to maintain clinical benefit. The absolute neutrophil count (ANC) should not be the sole indicator of clinical efficacy. Individually adjust dosages on the basis of both the patient's clinical course and the ANC.
Consider bone marrow transplantation only in patients unresponsive to therapy with G-CSF or in those with leukemic transformation.
Colony-stimulating factors
Class Summary
These agents are used to stimulate neutrophil production and act as hematopoietic growth factors that stimulate the development of granulocytes. They are used to treat or prevent neutropenia.
Filgrastim (G-CSF, Neupogen)
Recombinant methionyl human G-CSF (r-metHuG-CSF) consisting of a 175-amino acid protein with a molecular weight of 18,800 d. Produced by Escherichia coli bacteria into which the human G-CSF gene is inserted. This protein has an amino acid sequence identical to the natural sequence predicted from human DNA sequence analysis, except for the addition of an N -terminal methionine necessary for expression in E coli. Because it is produced in E coli, product is nonglycosylated and thus differs from G-CSF isolated from human cells.
