A 70-year-old man is evaluated for a persistent leukocytosis. The most likely diagnosis in otherwise unexplained leukocytosis in a hospitalized patient is less than .01). He was hospitalized 10 days ago for a severe exacerbation of chronic obstructive pulmonary disease. They described three patterns: one in which leukocytosis occurred at the onset of diarrhea; a pattern in which unexplained leukocytosis occurred days prior to diarrhea; and a pattern in which patients treated for infection with leukocytosis had a worsening of their leukocytosis at the onset of diarrheal symptoms. He was intubated for 3 days, was diagnosed with a left lower lobe pneumonia, and was treated with antibiotics. Treatment with metronidazole led to a resolution of leukocytosis in all the The elevation and rapidity of increase are dose related. His white blood cell count on admission was 20,000 per mc L. 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. It dropped as low as 15,000 on day 6 but is now 25,000, with 23,000 polymorphonuclear leukocytes (10% band forms). Importantly, increased band forms (greater than 6%) and toxic granulation rarely ever occur with steroid-induced leukocytosis, and the presence of these features should strongly suggest a different cause.

What should we think of in the patient whose WBC climbs in the hospital, and the cause isn’t readily apparent? Often, the patient may well be improving from the condition that they were originally hospitalized for, but the climbing WBC count is concerning and often delays discharge. terbinafine for dogs side effects From the *Centro Nacional de Enfermedades Reumáticas, Servicio de Reumatología, Hospital Universitario de Caracas, Caracas, Venezuela; and †Division of Rehabilitation Sciences/Sealy Center on Aging, University of Texas, Medical Branch, Galveston, Texas.

It is important for clinicians to be aware of this expected side effect and to understand the rationale for such an increase as well as appropriate interpretation of the labs given the patient's clinical condition. Keeping all of these things in mind will help clinicians avoid unnecessary medical work-up for other conditions and avoid patient exposure to additional drug therapy that is not warranted, such as intravenous antibiotics. The long-term pattern of prednisone-induced leukocytosis was examined in 80 patients. Our results disclosed an extremely variable leukocytic response, in which the white blood cell count surpassed 20,000/mm as early as the first day of treatment, an increase that persisted for the duration of therapy. 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. The leukocytosis was attributed predominantly to a rise in the polymorphonuclear white blood cells, a phenomenon that coincided with monocytosis, eosinopenia and a variable degree of lymphopenia. It can be concluded that even small doses of prednisone, administered over a prolonged period of time, can induce extreme and persistent leukocytosis. This observation is of consequence especially when infection is suspected, particularly in an immunocompromised host.
