neutropenia

Neutropenia is a condition characterized by an abnormally low count of neutrophils, a type of white blood cell. This reduction in neutrophils, which are crucial for fighting bacterial infections, can lead to frequent and severe infections.12

Neutropenia can be caused by various factors, including:
* Drug reactions: Certain medications can trigger an immune response where antibodies destroy neutrophils.1
* Bone marrow damage: Chemotherapy drugs used for cancer treatment, as well as other medications like pain relievers and antihistamines, can harm the bone marrow, affecting neutrophil production.1
* Infections and diseases: Conditions such as typhoid fever, measles, HIV infection, and diseases affecting the bone marrow or spleen are also associated with neutropenia.1
* Radiation: High doses of radiation can also cause neutropenia.1

While neutropenia itself may not cause symptoms, the increased susceptibility to infections is a significant concern. Treatment focuses on addressing the underlying cause of the low neutrophil count.1
