Chronic neutrophilia

Last edited: 4/10/2026

Overview

Chronic neutrophilia is a persistent elevation of neutrophil counts in the blood. This condition can be associated with various underlying causes, including infections, inflammatory conditions, and hematologic malignancies.

Diagnosis

  • Diagnosis is based on repeated complete blood counts demonstrating an elevated absolute neutrophil count.
  • Further investigation is guided by clinical suspicion and may include inflammatory markers, infectious workup, and peripheral blood smear review.
  • Management

  • Management focuses on identifying and treating the underlying cause of chronic neutrophilia.
  • For asymptomatic individuals with benign causes, observation may be sufficient.
  • For symptomatic patients or those with serious underlying conditions, specific treatments targeting the etiology are required.
  • Special Populations

  • Pediatric patients may require age-specific evaluation and management strategies.
  • Key Recommendations

  • Adherence to prophylaxis in hemophilia patients is influenced by acceptance and self-management skills 1.
  • Learning self-infusion in hemophilia is typically initiated before puberty, with full self-management achieved approximately 10 years later 1.
  • Adherence levels to prophylaxis in hemophilia vary by age, with the highest levels in children (1-12 years) and the lowest in adults aged 25-40 years 1.
