Living with primary ciliary dyskinesia

Overview

Primary ciliary dyskinesia (PCD) is a rare inherited condition that affects tiny hair-like structures in the body called cilia. In healthy people, cilia move in a wave-like pattern to help clear mucus, dust, and germs from the airways. In PCD, cilia don't work properly, so mucus builds up in the lungs, ears, sinuses, and other organs. This can lead to repeated infections, breathing problems, and other issues. There is no cure, but with the right care, most people with PCD can manage their symptoms and live a full life.

Primary ciliary dyskinesia is rare. It affects about 1 in 10,000 to 1 in 40,000 people worldwide, though many cases may be undiagnosed because symptoms can be similar to other common breathing problems.

PCD is genetic, meaning it runs in families. Symptoms usually begin in childhood, often with breathing problems, chronic nasal congestion, and ear infections. However, some people are not diagnosed until they are adults, especially if their symptoms are mild or mistaken for asthma or allergies.

Symptoms

Common symptoms

• A chronic, wet cough that lasts most days and brings up mucus, starting in early childhood
• Frequent chest colds, pneumonia, or bronchitis
• Chronic nasal congestion, a constantly runny or stuffy nose, and sinus infections
• Recurring ear infections, especially in children
• Difficulty clearing mucus from the lungs, which may get worse at night or in the morning
• Breathing discomfort, wheezing, or shortness of breath with activity
• In many full-term newborns, unexplained breathing trouble (respiratory distress) shortly after birth
• Fertility problems in adulthood for some people, due to cilia not moving properly in sperm or fallopian tubes

Symptoms in children

• Nose nearly always runs or is blocked from early infancy
• Repeated ear infections, sometimes with glue ear, which can affect hearing
• A wet and rattling cough that is present every day, often starting in the first few weeks of life
• Pneumonia or chest infections that keep coming back
• Unexplained breathing difficulties as a newborn, even without premature birth
• Slow growth or failure to thrive in some children due to ongoing illness

Symptoms in older adults

• Long-standing lung problems, including bronchiectasis, which is permanent widening and scarring of the airways
• Chronic cough that produces a lot of mucus daily and may worsen with age
• Increasing breathlessness and reduced exercise capacity
• Sinus disease and nasal polyps that may need repeated treatment
• Hearing loss related to chronic ear problems
• Thinning of the bones (osteoporosis) in some adults, especially if they take long-term steroid medicines

Causes

Main causes

• Primary ciliary dyskinesia is caused by changes (mutations) in specific genes that affect the structure or function of cilia
• These gene changes are passed down from parents to children in an autosomal recessive pattern, meaning a child must inherit the altered gene from both parents to have the condition
• Because cilia are found in many parts of the body, PCD can affect the lungs, ears, sinuses, organs, sperm, and fallopian tubes

Risk factors

• Having a family history of PCD
• Being born to parents who are closely related (such as cousins), which can increase the risk of rare genetic conditions
• Having siblings with PCD or with mirror-image organ placement

When to see a doctor

See a doctor urgently if:

• If you or your child has persistent coughing, especially with green or yellow mucus, and a sudden change in breathing that doesn't settle quickly
• If symptoms of a chest infection are severe or getting worse despite treatment
• If your child has repeated ear infections and you suspect new hearing loss

Book a routine appointment if:

• If you or your child has a daily productive cough that has lasted more than a few weeks, especially since early childhood
• If there are recurring chest infections, sinus infections, or ear infections without a clear cause
• If you have chronic nasal congestion that doesn't improve with typical treatments
• If you or your child was assigned female at birth and are considering pregnancy, or if you are trying to conceive and have concerns
• If you have unexplained fertility problems and think PCD might be a cause

Diagnosis

Diagnosing PCD usually starts with a detailed medical history and physical exam, especially if symptoms began in infancy and include daily cough, chronic nasal congestion, and ear infections. Because PCD is rare, your doctor may refer you to a specialist center for genetic testing and specialized tests of cilia function.

Tests that may be done

• Measurement of nitric oxide levels in the nose, which is often lower in people with PCD
• Genetic testing, which looks for changes in genes known to cause PCD
• A sample of cells from the nose or windpipe (nasal brushing) to examine cilia under a microscope
• A high-speed video test to see whether cilia are moving normally
• Chest X-ray or CT scan to look for lung changes such as infections or bronchiectasis
• Other tests to check for sinus and ear problems, if needed

What to expect at your appointment

The diagnostic process can take time, and you may need to travel to a specialist clinic. Tests are usually painless, but some, like nasal brushing, can be slightly uncomfortable. You may need to repeat some tests after a period of active infection, because infection can temporarily affect how cilia look and move. If you have PCD, your care team will discuss what this means for you and your family and start planning a treatment approach.

Treatment

There is no cure for PCD, but treatment focuses on keeping airways clear, treating and preventing infections, monitoring lung function, and managing symptoms in other parts of the body. Care is usually provided by a team that includes respiratory doctors, physiotherapists, ear nose and throat specialists, and other experts. The aim is to maintain lung health, reduce complications, and help you live as normally as possible.

Self-care at home

• Perform daily airway clearance (also called chest physiotherapy) to loosen mucus — your physiotherapist can teach you techniques that work for you
• Use a home exercise program recommended by your care team, and stay active in whatever way feels comfortable
• Keep up with routine vaccinations, including flu and pneumonia vaccines, to help prevent infections
• Avoid smoke, pollution, strong fumes, and other lung irritants
• Drink plenty of fluids unless your doctor advises otherwise, to help keep mucus thinner
• Take prescribed medications exactly as directed and finish any courses of antibiotics fully
• Wash your hands often and practice good hygiene to reduce exposure to germs

Medical treatments

Medical treatment for PCD is tailored to each person. It includes inhaled medicines to open the airways and thin mucus, as well as antibiotics for bacterial infections and sometimes daily antibiotics to prevent infections in people who need them. Inhaled corticosteroids may be used if there is an asthma-like component. Ear infections, sinus infections, and hearing problems may be treated with a combination of medicines, sinus rinses, and sometimes ear tubes. Fertility treatments are possible for adults with PCD who want to have children. All treatments must be prescribed and monitored by a qualified healthcare provider — never self-prescribe. The exact approach will depend on your symptoms, lung function, and overall health.

When is surgery considered?

Surgery is not a routine treatment for PCD itself, but it may be needed for complications. Common examples include ear ventilation tubes for chronic ear effusions, sinus surgery for persistent sinus disease or nasal polyps, and lung surgery in rare, severe cases of bronchiectasis or other lung damage. These decisions are made on an individual basis with specialist teams.

Living with this condition

Living with PCD usually involves building a daily routine. Airway clearance is often done once or twice a day, sometimes more during a chest infection. You'll learn to adapt your routine to fit school, work, and social life. Many people with PCD develop a way to manage their symptoms that becomes second nature. It helps to stay connected with your care team, keep regular appointments, and tell them about any changes in your health.

Lifestyle tips

• Keep a daily routine for chest clearance and stick with it, even when you feel well
• Exercise regularly — physical activity helps clear mucus, improves fitness, and supports lung health
• Plan ahead for travel, including packing enough medications and knowing how to access care away from home
• Avoid smoking and secondhand smoke entirely
• Wear a medical alert bracelet or carry information about your condition in case of emergencies
• Join a support group or online community for people with PCD and their families

Diet and exercise

Eat a balanced, varied diet with plenty of fruits, vegetables, whole grains, and lean proteins to support your immune system. Staying well-hydrated is especially important for keeping mucus easier to clear. Exercise is beneficial for PCD — it helps create airway movement, encourages coughing to clear mucus, and keeps your heart and lungs strong. Work with your care team to find an exercise plan that feels achievable. If you have other health issues, ask your doctor or physiotherapist for advice.

Mental health and emotional wellbeing

Living with a chronic illness like PCD can be emotionally and mentally challenging. You may feel tired, frustrated, or embarrassed by a constant cough or the need for daily treatment. Some people experience anxiety or low mood, especially if symptoms are severe or affect daily life. These feelings are common and nothing to be ashamed of. If you are struggling, speak to your healthcare team — they can connect you with mental health support. If you feel overwhelmed or have thoughts of self-harm, please reach out to emergency services or a crisis helpline immediately. You are not alone.

Prevention

Because PCD is a genetic condition, it cannot be prevented. The gene changes are not caused by anything you did. What can be prevented or delayed are some complications, through early diagnosis, regular specialist care, daily airway clearance, respiratory vaccinations, and prompt treatment of infections.

Vaccines

Vaccination is not a treatment for PCD itself, but it is an important way to reduce the risk of respiratory infections. Standard childhood vaccines, the seasonal flu vaccine, and some pneumonia vaccines are often recommended for people with PCD, as they are for many people with long-term lung conditions. Ask your doctor or local health service about the vaccines that are right for you or your child. Do not stop or skip prescribed treatments.

Screening programmes

There is no routine newborn screening for PCD in most countries, although some research is ongoing. If you have a family history of PCD or a child with symptoms, genetic counseling and testing may be available. In some regions, newborn screening programs are beginning to include PCD, but this varies. If you are worried, talk to a healthcare provider about whether testing is appropriate for your family.

Complications

If left untreated

• Permanent lung damage, including bronchiectasis, where airways become enlarged and scarred, making it harder to clear mucus and fight infection
• Chronic respiratory failure, needing oxygen therapy or, in severe cases, lung transplant
• Persistent ear infections that can lead to permanent hearing loss in children and adults
• Sinus disease and nasal polyps that may require repeated surgery
• Reduced exercise capacity and overall poor lung function over time
• Fertility problems, due to sperm mobility issues in males and fallopian tube cilia issues in females
• Severe, repeated pneumonia that can be life-threatening

Long-term outlook

With proper treatment and regular follow-up, many people with primary ciliary dyskinesia live long and fulfilling lives. The outlook has improved dramatically in recent years due to better airway clearance techniques, earlier diagnosis, and improved infection management. Some people need a lot of treatment, but many others lead very active lives with career, family, and hobbies. The key is building a strong relationship with a specialist care team and staying committed to daily management. It is entirely possible to find joy and purpose while living with PCD.
