Interest in the procedure increased in the 1990s due to the development of more effective methods for harvesting granulocytes and a growing population of people with severe neutropenia from chemotherapy. However, the treatment's efficacy remains poorly understood and its use is controversial. [2] [3] [4]
The most important and often life-saving treatment is the preventive therapy of granulocyte colony-stimulating factor (G-CSF), in the form of filgrastim, which regulates the production of neutrophils within the bone marrow, but shortens the neutropenic cycle to about 7-14 days and the duration of the severe condition.
Neutropenia is an abnormally low concentration of neutrophils (a type of white blood cell) in the blood. [4] Neutrophils make up the majority of circulating white blood cells and serve as the primary defense against infections by destroying bacteria, bacterial fragments and immunoglobulin-bound viruses in the blood.

Immunoglobulin therapy is the use of a mixture of antibodies (normal human immunoglobulin) to treat several health conditions. [13] [14] These conditions include primary immunodeficiency, immune thrombocytopenic purpura, chronic inflammatory demyelinating polyneuropathy, Kawasaki disease, certain cases of HIV/AIDS and measles, Guillain–Barré syndrome, and certain other infections when a ...
Leukapheresis (/ ˌ l u ˈ k ʌ f ɜːr iː s ɪ s / ⓘ) is a laboratory procedure in which white blood cells are separated from a sample of blood. It is a specific type of apheresis, the more general term for separating out one particular constituent of blood and returning the remainder to the circulation.
There is some variability in the neutrophil counts depending upon when the sample is taken, where the blood sample is taken from, and the system used by the medical lab for measuring the blood cells, but any significant reduction in function or number below the appropriate range may predispose individuals to infections.
In people with cancer who have febrile neutropenia (excluding patients with acute leukaemia), oral treatment is an acceptable alternative to intravenous antibiotic treatment if they are hemodynamically stable, without organ failure, without pneumonia and with no infection of a central line or severe soft-tissue infection. [11]
Autoimmune neutropenia (AIN) is a form of neutropenia which is most common in infants and young children [1] where the body identifies the neutrophils as enemies and makes antibodies to destroy them. Primary autoimmune neutropenia, another name for autoimmune neutropenia, is an autoimmune disease first reported in 1975 that primarily occurs in ...
