Neutropenia in Refugee Patients
Overview
Neutropenia is a common incidental finding in refugee patients. The most frequent cause in patients of African or Middle Eastern descent is benign ethnic neutropenia (BEN), a benign genetic condition with no increased risk of infection.
Benign Ethnic Neutropenia (BEN)
BEN is characterised by:
* Persistent mild neutropenia (ANC typically greater than 1.0, rarely below 1.0)
* Appropriate ethnic background (African, Middle Eastern)
* No history of recurrent infections
BEN is a genetic condition. It is more likely if other family members are also neutropenic.
Management by ANC Level
ANC (x10^9/L) | Action |
>1.5 | No follow-up required |
1.0-1.5 (mild) | Repeat at least one CBC (minimum 2 weeks apart). If still mild and not trending down in a patient of African or Middle Eastern descent, consider BEN. |
0.5-1.0 (moderate) | Repeat CBC and blood smear. Evaluate for other causes on history and exam. |
<0.5 (severe) | If symptomatic: evaluate urgently, preferably in hospital. If asymptomatic: call Hematology before referring. |
When to Investigate Further
Investigate for other causes (medications, infection, malignancy, liver disease) if:
* Patient has a history of recurrent infections
* Patient is of non-African/Middle Eastern ethnicity
* ANC is below 1.0 without a family history of neutropenia
* Patient has systemic symptoms such as fever, weight loss, or lymphadenopathy
