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. These cilia play a crucial role in moving mucus and other substances along the respiratory tract, reproductive system, and other organs.
The prevalence of PCD varies across different populations and regions. It is estimated to affect approximately 1 in every 10,000 to 40,000 individuals worldwide. However, due to underdiagnosis and misdiagnosis, the true prevalence may be higher than reported.
PCD is often diagnosed in childhood or adolescence, but it can also be diagnosed in adulthood. The symptoms of PCD can vary widely, but commonly include chronic respiratory infections, persistent cough, nasal congestion, and fertility issues. The severity of symptoms can also vary, ranging from mild to severe.
Early diagnosis and management of PCD are crucial to prevent complications and improve quality of life. Genetic testing and specialized diagnostic tests, such as nasal nitric oxide measurement and high-speed video microscopy, are used to confirm the diagnosis.
While PCD is a rare disorder, raising awareness among healthcare professionals and the general public is important to ensure timely diagnosis and appropriate management for individuals affected by this condition.
