A number of conditions may result in acquired defects in neutrophil function, which may be associated with an increased risk for infection.
Possible neutrophil dysfunctions:
(1) defects in adhesion
(2) defects in cytoplasmic granules
(3) defect in motility and chemotaxis
(4) defects in phagocytosis and killing (defect in oxidative metabolism, other)

• Hematologic disorders include myelodysplasia, myeloproliferative disorders and AML.
• Chronic infections may be a chicken and egg situation (hard to know which came first) and may be associated with other conditions.
