Which are the symptoms of Cyclic Neutropenia?

Cyclic Neutropenia is a rare hematological disorder characterized by recurrent episodes of abnormally low levels of neutrophils, a type of white blood cell, typically occurring in a predictable 21-day cycle. Common symptoms during these nadir periods include mouth ulcers, fever, infections, and inflammation, which resolve as neutrophil counts recover.

What are the most common symptoms of Cyclic Neutropenia?

The clinical presentation of Cyclic Neutropenia revolves around the periodic drop in neutrophils. During the low-count phase (nadir), which usually lasts 3 to 7 days, patients commonly experience:

• Recurrent fever and chills


• Painful aphthous stomatitis (mouth ulcers)


• Gingivitis (gum inflammation) and periodontitis


• Skin infections or abscesses


• Pharyngitis (sore throat)


• Lymphadenopathy (swollen lymph nodes)

How does Cyclic Neutropenia impact daily quality of life?

For the 25 members of the Cyclic Neutropenia community on DiseaseMaps.org, the primary burden is the predictability—and yet the disruption—of these cycles. Quality of life is often impacted by the chronic nature of oral pain, which can make eating and speaking difficult, and the anxiety surrounding the risk of secondary infections during the neutropenic phase.

When should I seek immediate medical attention?

While Cyclic Neutropenia symptoms are often manageable, patients must be vigilant for signs of severe infection. Seek emergency care if you experience a high fever (typically over 38.3°C or 101°F), signs of sepsis, or rapidly spreading skin infections, as the body’s inability to mount an effective immune response during the nadir can make minor infections progress to life-threatening emergencies quickly.

How does the severity of Cyclic Neutropenia vary?

The severity of Cyclic Neutropenia is highly variable between individuals. Some patients may only experience mild oral discomfort and fatigue, while others may suffer from severe, recurring systemic infections. Because Cyclic Neutropenia is usually caused by mutations in the ELANE gene, genetic factors play a significant role in determining the intensity of the cycles and the overall clinical course.

Next steps

• Consult a hematologist or immunologist to establish a baseline for your specific cycle.


• Maintain a symptom diary to track the timing of your Cyclic Neutropenia episodes.


• Join the Cyclic Neutropenia community at DiseaseMaps.org to connect with others sharing similar experiences.


• Discuss the use of Granulocyte Colony-Stimulating Factor (G-CSF) with your physician to potentially shorten the duration of neutropenic periods.
