Infections in non-neutropenic patients
Patients with normal or relatively normal neutrophil count may also have atypical infections in leukemia. These patients may be subject to steroids and other immunosuppressive agents that increase the risk of infections such as meningitis by Listeria monocytogenes or pneumonia by Pneumocystis jirovecci. In cases of listeriosis, ampicillin is often the drug of choice, but doctors may also consider using vancomycin, fluoroquinolones and even carbapenems depending on the sensitivity of the strain.
Other infections in this group of patients include viral infections (Herpes zoster virus, and Epstein-Barr virus), tuberculosis and atypical mycobacterial infections in cases of chronic leukemia.
