Neutropenia, a subtype of leukopenia, refers to a decrease in the number of circulating neutrophil granulocytes, the most abundant white blood cells. The terms leukopenia and neutropenia may occasionally be used interchangeably, as the neutrophil count is the most important indicator of infection risk. Agranulocytosis is an acute form of ...
Viruses that infect neutrophil progenitors can also be the cause of neutropenia. Viruses identified that have an effect on neutrophils are rubella and cytomegalovirus. [1] Though the body can manufacture a normal level of neutrophils, in some cases the destruction of excessive numbers of neutrophils can lead to neutropenia. These are: [1]
The following terms can be used to specify the type of granulocyte referenced: Inadequate numbers of neutrophils: neutropenia (most common) Inadequate numbers of eosinophils: eosinopenia (uncommon) Inadequate numbers of basophils: basopenia (very rare) In a general sense the pathogenesis of neutropenia can be divided into two categories;
A major challenge in treating FS is recurring infection caused by neutropenia. Therefore, in order to decide upon and begin treatment, the cause and relationship of neutropenia with the overall condition must be well understood. [9] Most of the traditional medications used to treat RA have been used in the treatment of Felty's syndrome.
Some drugs, such as prednisone, have the same effect as cortisol and adrenaline (epinephrine), causing marginated neutrophils to enter the blood stream. Overdoses of some drugs can cause very high levels of neutrophils in the blood. [citation needed] There is a single case report of severe neutrophilia with bupropion overdose. [3]
Signs and symptoms are nonspecific and generally related to the blood cytopenias: Anemia (low RBC count or reduced hemoglobin) – chronic tiredness, shortness of breath, chilled sensation, sometimes chest pain [6] Neutropenia (low neutrophil count) – increased susceptibility to infection [7]
This is noticed in some patients who are taking antipsychotic medication. Morning pseudoneutropenia is thought to be due to diurnal variation in the amount of circulating white blood cells and changes in the levels of hematopoietic cytokines and granulocyte colony stimulating factor (GCSF). [ 1 ]
The treatments for cytopenia vary depending on the type of cytopenia. The treatment for anemia is rest and a diet consisting of high iron foods. Medication can also be used such as: [citation needed] Epoetin alfa, a synthetic erythropoietin that stimulates stem cells to produce red blood cells.
