Abstract:
Cyclic neutropenia (CN) is a kind of hereditary disease with periodic onset of neutrophil reduction and recurrent infection,which can be sporadic or familial.CN was firstly reported in 1910,and it was not until 1999 that the cause of the CN was further identified by investigators.Because the incidence of CN is low,the disease is rarely reported in China.CN is caused by mutations in the gene for neutrophil elastase (ELA-2 or ELANE),and it is a rare,inherited autosomal dominant disorder.Diagnosis of CN is based on the medical history and blood cycle characteristics.With the continuous development of medical technology,gene testing has certain significance for the diagnosis of CN.For the treatment,the most important is infection prevention,symptomatic treatment,the use of granulocyte colony-stimulating factor,and so forth.Although CN is a hematological disease,most cases have good prognosis,and will not result in malignant hematological diseases such as leukemia.At present,the doctors' awareness of CN has been lacking,which leads to misdiagnosis.The symptom and sign are not specific at the onset of CN,thus there is often misdiagnosis.In order to deepen the understanding of this disease and improve the skills of diagnosis and treatment,this review summarizes the pathogenesis,clinical manifestation,clinical characteristics,diagnosis and treatment of CN.
