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 . [ 5 ]
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 ...
After the first year of life neutropenia is defined by absolute counts less than 1500/uL. Neutropenia may be primary in which it is the only blood abnormality seen. In secondary neutropenia, other primary conditions occur, including other autoimmune diseases, infections, and cancers. Neutropenia is considered chronic when it persists for more ...
The Multinational Association for Supportive Care in Cancer (MASCC) risk index can be used to identify low-risk patients (score ≥21 points) for serious complications of febrile neutropenia (including death, intensive care unit admission, confusion, cardiac complications, respiratory failure, kidney failure, low blood pressure, bleeding, and ...
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 ]
Cyclic neutropenia (CyN) is a rare hematologic disorder and form of congenital neutropenia that tends to occur approximately every three weeks and lasting for few days at a time due to changing rates of neutrophil production by the bone marrow.
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. Darbepoetin alfa stimulates red blood cells but requires less daily doses and less disruption in activities.
Diagnosis is established based upon several tests, among which can be blood tests (neutropenia, white blood cell count), urinalysis (increased urinary organic acid levels), echocardiography (cardiac ultrasound, to assess (and detect abnormalities in) the heart's structure, function and condition), and, with reasonable suspicion of Barth ...
