Leukopenia

Leukopenia or leukocytopenia is a decrease in the number of leukocytes in the peripheral blood below the physiological limit (ie approximately 4×109/l). It can often be caused by neutropenia or lymphocytopenia.

Other causes include infections (most often bacterial sepsis, infectious mononucleosis or hepatitis B virus ), adverse drug effects (most often chemotherapeutics, thyrostatics, antibiotics, analgesics, antiphlogistics, or neuropsychotropic drugs ), or it can be an accompanying phenomenon of other diseases, like systemic or bone marrow disease.
