Febrile neutropenia or neutropenic fever is a defined as a single oral temperature value of ≥ 38.3 C (101 F) or a temperature ≥ 38 C (100.4 F) for ≥ 1 hour, with an absolute neutrophil count (ANC) < 1500 cell/microliter. [1] In case of severe neutropenia, the ANC is < 500 cell/microliter. [1]
A fever, when combined with profound neutropenia (febrile neutropenia), is considered a medical emergency and requires broad spectrum antibiotics. An absolute neutrophil count less than 200 is also considered a medical emergency and almost always requires hospital admission and initiation of broad spectrum antibiotics with selection of specific ...
The use of these agents should be considered in individuals exposed to doses above 1.5 Gy, should be given to those who develop fever and neutropenia and should be administered within 48 hours of exposure. An estimation of the exposure dose should be done by biological dosimetry whenever possible and by detailed history of exposure.
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 ...
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.
In the US, efbemalenograstim alfa is indicated to decrease the incidence of infection, as manifested by febrile neutropenia, in adults with non-myeloid malignancies receiving myelosuppressive anti-cancer drugs associated with a clinically significant incidence of febrile neutropenia.
Fever (defined as a temperature >100.3 °F, >38 °C) Enlargement of the spleen; Decreased blood cell counts affecting at least two of three lineages in the peripheral blood: Haemoglobin <9 g/100 ml (in infants <4 weeks: haemoglobin <10 g/100 ml) Platelets <100×10 9 /L (thrombocytopenia) Neutrophils <1×10 9 /L (neutropenia)
Neutropenia indicates a deficiency of neutrophils (the most common granulocyte cell) only. [citation needed] To be precise, neutropenia is the term normally used to describe absolute neutrophil counts (ANCs) of less than 500 cells per microlitre, whereas agranulocytosis is reserved for cases with ANCs of less than 100 cells per microlitre.
