Do Steroids Increase Wbc?

Prednisone can increase WBC as early as the first day of therapy. The elevation and rapidity of increase are dose related. The important pearl is that steroid-induced leukocytosis involves an increase of polymorphonuclear white blood cells with a rise in monocytes and a decrease in eosinophils and lymphocytes.

How long is WBC elevated after steroids?

Although the degree of leukocytosis was related to the dosage administered, it did appear sooner with higher doses. Leukocytosis reached maximal values within two weeks in most cases, after which the white blood cell count decreased, albeit not to pretreatment levels.

Why do steroids cause elevated WBC?

WBC trafficking from the endothelium into the tissues is therefore altered. This demargination effect, coupled with the release of immature WBCs from the bone marrow by steroids, explains why we see an apparent increase in WBC.
