Leukopaenia means a low white cell count, & is quite common
in lupus patients.
If a patient's white blood cell count falls below 3000, they are
thought to have leukopaenia, & it may suggest that they are
about to have a flare.
Corticosteroids can be given to bring the white cell level back
to normal.
But if the cell count is low because the patient is receiving chemotherapy,
a chemical called cytokine may be administered in order to bring
the cell count back to normal, thereby preventing fever or infection.
