Primary Ciliary Dyskinesia

Disease database

Primary Ciliary Dyskinesia (PCD) is a rare genetic disorder that affects the function of cilia, which are tiny hair-like structures found on the surface of cells in various parts of the body. These cilia play a crucial role in moving mucus and other substances along the respiratory tract, reproductive system, and other organs. When the cilia are not functioning properly, it can lead to a range of symptoms and complications.

Chronic Cough

One of the most common symptoms of PCD is a chronic cough that persists for an extended period of time. This cough is often productive, meaning that it produces phlegm or mucus. The cough may be worse in the morning or after physical activity. It is important to note that a chronic cough can have various causes, so it is essential to consult a healthcare professional for an accurate diagnosis.

Recurrent Sinusitis

Individuals with PCD often experience recurrent sinus infections, known as sinusitis. The cilia in the nasal passages are responsible for clearing mucus and preventing bacteria and other pathogens from causing infections. When the cilia are not functioning properly, mucus can accumulate, leading to frequent sinus infections. Symptoms of sinusitis may include facial pain, nasal congestion, and post-nasal drip.


Bronchiectasis is a condition characterized by the widening and scarring of the airways in the lungs. In PCD, the impaired ciliary function can lead to the accumulation of mucus in the airways, which can become a breeding ground for bacteria. Over time, this can cause inflammation and damage to the airways, resulting in bronchiectasis. Symptoms of bronchiectasis may include chronic cough, shortness of breath, and recurrent chest infections.


PCD can also affect the reproductive system, leading to infertility in both males and females. In males, the impaired ciliary function can prevent sperm from reaching the egg, while in females, it can interfere with the movement of the egg through the fallopian tubes. Infertility can be a challenging aspect of PCD for individuals and couples who wish to start a family. However, assisted reproductive technologies, such as in vitro fertilization, may offer options for those affected by PCD.

Situs Inversus

Situs inversus is a condition in which the organs in the chest and abdomen are reversed or mirrored from their normal positions. It is estimated that approximately 50% of individuals with PCD also have situs inversus. This means that their heart is located on the right side of the chest instead of the left, and other organs may also be reversed. Situs inversus does not typically cause any health problems, but it can complicate medical procedures and diagnoses.

Otitis Media

Otitis media, or middle ear infection, is a common complication of PCD. The impaired ciliary function in the Eustachian tubes, which connect the middle ear to the back of the throat, can lead to the accumulation of fluid and bacteria in the middle ear. This can cause pain, hearing loss, and recurrent infections. Prompt treatment of otitis media is essential to prevent complications and preserve hearing.

Hearing Loss

Hearing loss can occur in individuals with PCD due to recurrent ear infections and damage to the middle ear. It is important to monitor hearing regularly and seek appropriate interventions, such as hearing aids, if necessary. Early intervention can help minimize the impact of hearing loss on communication and overall quality of life.

Respiratory Distress in Neonates

PCD can present with respiratory distress in newborns, often shortly after birth. The impaired ciliary function can lead to difficulty in clearing mucus from the airways, resulting in respiratory distress. Prompt medical attention is crucial in these cases to ensure adequate oxygenation and support for the newborn.

Treatment and Management

While there is currently no cure for PCD, there are various treatment and management strategies that can help alleviate symptoms and improve quality of life. These may include:

  • Regular airway clearance techniques, such as chest physiotherapy and the use of devices like a flutter valve or positive expiratory pressure mask, to help clear mucus from the airways.
  • Antibiotics to treat and prevent respiratory infections.
  • Nasal saline rinses to help keep the nasal passages clear.
  • Hearing aids or other interventions for individuals with hearing loss.
  • Fertility treatments, such as in vitro fertilization, for individuals experiencing infertility.

It is important for individuals with PCD to work closely with a multidisciplinary healthcare team, including pulmonologists, otolaryngologists, and fertility specialists, to develop a personalized treatment plan. Regular monitoring and follow-up appointments are essential to manage symptoms and prevent complications.

In conclusion, Primary Ciliary Dyskinesia is a complex genetic disorder that affects multiple systems in the body. It can cause chronic cough, recurrent sinusitis, bronchiectasis, infertility, situs inversus, otitis media, hearing loss, and respiratory distress in neonates. While there is no cure for PCD, early diagnosis and appropriate management can help individuals lead fulfilling lives and minimize the impact of the disease on their overall health and well-being.
