Autoimmune neutropenia (AIN) is a form of neutropenia which is most common in infants and young children [1] where the body identifies the neutrophils as enemies and makes antibodies to destroy them. Primary autoimmune neutropenia, another name for autoimmune neutropenia, is an autoimmune disease first reported in 1975 that primarily occurs in ...
Neutropenia itself is a rare entity, but can be clinically common in oncology [35] and immunocompromised individuals as a result of chemotherapy (drug-induced neutropenia). Additionally, acute neutropenia can be commonly seen from people recovering from a viral infection or in a post-viral state.
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 ...
Symptoms of neutropenia are associated with the underlying cause of the decrease in neutrophils. For example, the most common cause of acquired neutropenia is drug-induced, so an individual may have symptoms of medication overdose or toxicity. Treatment is also aimed at the underlying cause of the neutropenia. [21]
Although mutations of more than 15 genes cause severe congenital neutropenia (in a general sense) [19] not all of these are usually considered as SCN. Clinical usage excludes two broad categories of congenital neutropenia. Diseases are excluded that overtly affect multiple systems rather than impacting myelopoiesis most prominently.
Hematologic abnormalities: neutropenia may be intermittent or persistent and is the most common hematological finding. Low neutrophil counts leave patients at risk of developing severe recurrent infections that may be life-threatening.
Autoimmune disease is the second most common clinical manifestation and one that most often requires treatment. The most common autoimmune presentations include autoimmune cytopenias, which can be mild to very severe and intermittent or chronic. [5] These include autoimmune hemolytic anemia, autoimmune neutropenia, and autoimmune thrombocytopenia.
In 88% to 100% of patients with SDS, neutropenia—generally defined as a neutrophil count of less than 1,500 109/L—is the most prevalent sign of bone marrow failure. About two thirds of patients have intermittent neutropenia, while the remaining third have chronic neutropenia. Neutrophil counts can be anywhere from normal to very low. [17]
