Introduction[edit | edit source]
Neutropenia is a low level of neutrophils in the blood[1]. Neutrophils are a type of white blood cell, that support the immune system to fight injection by ingesting and killing invading microorganisms[2]. Neutropenia is defined as less than 1500 neutrophils per micro-litre of blood. It can be classed as mild (1000 to 1500 neutrophils per micro-litre), moderate (500 to 1000 neutrophils per micro-litre) or severe (less than 500 neutrophils per micro-litre)[3]. Neutropenia leads to an increased risk of infection and this risk is directly correlated with how long a patient has been neutropenic and how severe the neutropenia is. [3].
Aetiology[edit | edit source]
Neutropenia can develop due to a wide range of one or more causes[4].
Neutropenia can be caused by[5]:
- Congenital neutropenia
- Infection
- Medicine, including Chemotherapy
- Autoimmune response
- Malignancy
- Dietary deficiencies
Clinical Presentation[edit | edit source]
Neutropenia itself is asymptomatic until an infection develops, whereby fever is the primary symptom[6]. Usual signs of inflammation and infection can occur but may be reduced in neutropenic patients, due to the reduced immune response[7].
Diagnostic Procedures[edit | edit source]
- Subjective assessment to get full medical history[8].
- Physical examination for focal symptoms[6].
- Full blood count including creatinine and CRP[7].
- Chest radiography for patients with respiratory symptoms[7].
- Bacteria and fungi cultures[7].
Management[edit | edit source]
- Antibiotics: timely administration when a patient is febrile significantly improves mortality rate[9][10].
- Intervention to treat the underlying cause of the neutropenia[11].
- Granulocyte-colony stimulating factor (G-CSF): stimulates the bone marrow to produce neutrophils[11].
- Basic lifestyle modifications are advised to reduce risk of infection[11].
