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]

[38] [39] Conditions that indicate the presence of neutropenic fever are implanted devices; leukemia induction; the compromise of mucosal, mucociliary and cutaneous barriers; a rapid decline in absolute neutrophil count, duration of neutropenia >7–10 days, and other illnesses that exist in the patient. [31] Signs of infection can be subtle.

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 ...

Neutropenic enterocolitis, also known as typhlitis, is an inflammation of the cecum (part of the large intestine) that may be associated with infection. [1] It is particularly associated with neutropenia , a low level of neutrophil granulocytes (the most common form of white blood cells ) in the blood.
In Felty's syndrome, chronic activation of neutrophils progresses to neutropenia and unabated infections. [9] Neutropenia is a decreased concentration of neutrophils in the blood. Neutrophils are the most abundant cells among white blood cells and play an important role in the immune system by destroying bacteria via phagocytosis. Inflammatory ...
