Insights
Primary ciliary dyskinesia (PCD) is often diagnosed late in childhood. Key symptoms include neonatal respiratory distress, chronic cough, and rhinosinusitis, prompting a need for increased clinical awareness.
Area of Science:
- Pediatric Pulmonology
- Rare Diseases
- Genetics
Background:
- Primary ciliary dyskinesia (PCD) is a rare genetic disorder affecting approximately 1 in 15,000 individuals.
- It leads to recurrent respiratory infections, progressive lung damage, and hearing loss, often with delayed diagnosis.
- Early recognition is crucial for timely management and improved patient outcomes.
Purpose of the Study:
- To review the presenting clinical features of children diagnosed with PCD.
- To analyze diagnostic patterns over a 30-year period at Australia's primary PCD diagnostic service.
- To identify common symptom clusters associated with PCD in pediatric patients.
Main Methods:
- Retrospective review of pediatric patients diagnosed with PCD between 1982 and 2012.
- Inclusion criteria: diagnosis confirmed by nasal ciliary brushing, electron microscopy, or suggestive phenotype with genetic factors.
- Data collection focused on presenting symptoms, situs abnormalities, family history, and age at diagnosis.
Main Results:
- Out of 1,037 referred patients, 8.1% (84 children) were diagnosed with PCD.
- The median age at diagnosis was 6.4 years, indicating significant diagnostic delay.
- Common symptoms included neonatal respiratory distress (57%), recurrent cough (81%), rhinosinusitis (71%), and recurrent otitis media (49%).
- Situs abnormalities were present in 46% of patients, and bronchiectasis was noted in 32% at presentation.
Conclusions:
- PCD remains under-recognized by healthcare professionals.
- A combination of neonatal respiratory distress, chronic suppurative cough, and rhinosinusitis is a frequent presentation.
- Increased awareness of PCD's clinical manifestations can lead to earlier diagnosis and better long-term outcomes.
Aim:
Primary ciliary dyskinesia (PCD) is a rare (1:15,000) condition resulting in recurrent suppurative respiratory tract infections, progressive lung damage and hearing impairment. As the diagnosis is often delayed for years, the purpose of this study was to review the presenting features of children with PCD attending Australia's initial diagnostic PCD service over a 30-year period.
Method:
A retrospective review of the symptoms of children diagnosed with PCD at Concord Hospital between 1982 and 2012 was undertaken.
Results:
One thousand thirty-seven paediatric patients were referred for assessment and underwent nasal ciliary brushing. Eighty-four (8.1%) had PCD based on microscopic analysis of nasal cilia. This included 81 with ciliary ultrastructural abnormalities demonstrated on electron microscopy and 3 with a suggestive phenotype, reduced ciliary beat frequency and a family history of PCD. The median age at diagnosis was 6.4 years (range 0.1 to 18.2 years). Forty-six per cent had situs abnormalities and 31% had a family member with PCD. Recurrent cough (81%), rhinosinusitis (71%), recurrent otitis media (49%) and neonatal respiratory distress (57%) were reported. Bronchiectasis at presentation was documented in 32%. Situs abnormalities and neonatal respiratory distress were present together in 26%.
Conclusion:
PCD remains under-recognised by health-care workers. The combination of neonatal respiratory distress, chronic suppurative cough and rhinosinusitis was the most common documented symptom cluster at presentation in cases of PCD. A heightened awareness of the clinical features of the disease may help to lower the age at diagnosis, facilitate appropriate treatment and improve long-term outcomes.
