Primary Ciliary Dyskinesia: Causes, Symptoms, and Treatment

What kind of doctor treats Primary Ciliary Dyskinesia?
A lung specialist called a pulmonologist usually treats primary ciliary dyskinesia. This is a rare condition some people are born with that affects tiny hair-like parts in the airways. Many patients also see an ear, nose, and throat doctor. A primary care doctor often helps coordinate the whole care team.
What it is
Primary ciliary dyskinesia, or PCD, is a disease people are born with. It affects cilia, tiny hair-like parts that line the airways and ears. In PCD, cilia do not move the way they should, so mucus builds up and infections happen more often.
Symptoms
Symptoms often start in babies or young children. Common signs include a long-lasting stuffy nose, a wet-sounding cough, and frequent ear, sinus, and chest infections. Over time, repeated lung infections can damage the lungs.
Causes and who gets it
PCD is a genetic disease. A child must get one changed gene from each parent, and the parents usually have no symptoms. Experts think about 1 in 10,000 to 1 in 15,000 babies is born with it.
How doctors diagnose it
Doctors may start with a special camera test that looks at how cilia move in a sample from the nose. Genetic testing can confirm the diagnosis. Diagnosis can take time because the condition is rare.
Treatment
There is no cure for PCD, but treatment can help clear mucus and lower the number of infections. Many people do airway clearance, using special breathing methods or a vibrating vest. Doctors may prescribe antibiotics when infections happen.
When to see a doctor
Talk to a doctor if a child has a wet cough that lasts more than a few weeks or keeps getting ear or sinus infections. Anyone with PCD should see their care team regularly, because early treatment helps protect the lungs.
What kind of doctor treats it
A pulmonologist usually leads PCD care. Ear, nose, and throat doctors treat the ear and sinus problems. Some centers have PCD clinics with several specialists in one place. A direct primary care or concierge doctor can manage routine infections and refer the patient to a pulmonologist when needed.
Common questions
Is PCD the same as cystic fibrosis?
No, they are different diseases, but both cause mucus to build up in the lungs and lead to repeated infections. The genes involved and the treatments are not the same. Doctors can tell them apart with genetic testing and other tests.
Can people with PCD have children?
Many people with PCD can have children, though some men have lower fertility because cilia also help sperm move. Fertility treatments can help many couples. Anyone with PCD who wants a family can talk with a doctor about options.
Will my child outgrow PCD?
No, PCD is a lifelong condition because it comes from the genes a person is born with. Symptoms can get better or worse over time, and results differ from person to person. Regular care helps many people stay well.
How is PCD different from asthma?
Asthma is a condition where the airways swell and narrow, often with wheezing that comes and goes. PCD causes constant mucus buildup and repeated infections from cilia that do not move well. Some people have both conditions at once.
