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 ...
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]
Agranulocytosis, also known as agranulosis or granulopenia, is an acute condition involving a severe and dangerous lowered white blood cell count (leukopenia, most commonly of neutrophils) and thus causing neutropenia in the circulating blood. [1] It is a severe lack of one major class of infection-fighting white blood cells.
Like neutropenia, lymphocytopenia may be acquired or intrinsic and there are many causes. [19] This is not a complete list. Inherited immune deficiency – severe combined immunodeficiency , common variable immunodeficiency , ataxia–telangiectasia , Wiskott–Aldrich syndrome , immunodeficiency with short-limbed dwarfism , immunodeficiency ...
Leukopenia – a deficiency of white blood cells, or leukocytes [1] Neutropenia – a type of leukopenia, with a specific deficiency in neutrophils [2] Thrombocytopenia – a deficiency of platelets; Pancytopenia – when all three types of blood cells; red blood cells, white blood cells, and platelets, are all deficient.
Cyclic neutropenia (CyN), like severe congenital neutropenia (SCN), is a rare disorder. It is considered that in the general population, CyN has a frequency of one in one million. [ 1 ] It is the result of autosomal dominant mutation in ELANE gene located on the short arm (p) of chromosome 19 (19p13.3), the gene encoding neutrophil elastase ...
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]
MDS is diagnosed with any type of cytopenia (anemia, thrombocytopenia, or neutropenia) being present for at least 6 months, the presence of at least 10% dysplasia or blasts (immature cells) in 1 cell lineage, and MDS associated genetic changes, molecular markers or chromosomal abnormalities. [36] A typical diagnostic investigation includes:
