What is cyclic neutropenia?
Neutropenia is the medical term for a decrease in the number of white blood cells called neutrophils. Neutrophils are a very important part of the immune system. Neutrophils protect the body against bacterial infections. A person who has low neutrophils may be more susceptible to bacterial infections.
Cyclic neutropenia is a disorder that causes frequent infections and other health problems in affected individuals. People with this condition have recurrent episodes of neutropenia. The episodes of neutropenia are usually apparent at birth or soon afterward. For most affected individuals, neutropenia recurs every 21 days and lasts about 3 to 5 days.
What are the symptoms of cyclic neutropenia?
People with cyclic neutropenia typically develop recurrent infections of the sinuses, respiratory tract, and skin. Additionally, people with this condition often develop open sores (ulcers) in the mouth and colon, inflammation of the throat (pharyngitis) and gums (gingivitis), recurrent fever, or abdominal pain. People with cyclic neutropenia have these health problems only during episodes of neutropenia. At times when their neutrophil levels are normal, they are not at an increased risk of infection and inflammation
How is cyclic neutropenia diagnosed?
Diagnosis requires repeated blood tests at least two to three times per week for four to six weeks in order to document the cyclical nature of the neutropenia. Cyclic neutropenia can also be confirmed with gene testing. This disorder is associated with a known genetic mutation called ELANE. Occasionally a bone marrow test is required. Since this disorder is inherited, other family members may also be tested.
How is cyclic neutropenia treated?
Patients with cyclic neutropenia require prompt treatment of fevers and infections with antibiotics.
Treatment with a medication called granulocyte colony-stimulating factor (G-CSF) can help to increase the neutrophil count. Once the neutrophil count is within a normal range, generally the problems with infections will also improve. This medication is given by injection every day to every few days depending on the response.
