Categories:
Idiopathic neutropenia is an acquired form of severe chronic neutropenia whose cause is unknown.[1] Neutropenia is a blood condition that causes a reduced number or complete absence of neutrophils, a type of white blood cell that is responsible for much of the body's protection against infection. Symptoms include fever, moth sores, and other types of infections. Neutropenia idiopathic may occur in children and adults.[2] Frequency and severity of infections appear to be directly related to neutrophil count; while clinical problems in individual patients may vary, in general, those patients with more severe neutropenia have more frequent infections.[3] Most patients respond well to granulocyte-colony stimulating factor (G-CSF).[4] Long-term treatment is usually required.[2][3]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.

Healthcare Resources

Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.

Patient Registry

  • A registry supports research by collecting of information about patients that share something in common, such as being diagnosed with Idiopathic neutropenia. The type of data collected can vary from registry to registry and is based on the goals and purpose of that registry. Some registries collect contact information while others collect more detailed medical information. Learn more about registries.
