Insights
Diagnosis and treatment of Primary Ciliary Dyskinesia (PCD) in Austrian children are inconsistent. Further research is needed to understand disease progression and optimize care for pediatric PCD patients.
Area of Science:
- Pediatric Pulmonology
- Rare Genetic Diseases
- Respiratory Medicine
Background:
- Primary Ciliary Dyskinesia (PCD) is a rare, inherited disorder affecting cilia, leading to recurrent respiratory infections.
- Symptoms include chronic sinusitis, pneumonia, bronchitis, and bronchiectasis, with some patients exhibiting situs inversus.
- Chronic rhinitis is a common early symptom in infants and newborns.
Purpose of the Study:
- To determine the prevalence of pediatric Primary Ciliary Dyskinesia (PCD) in Austria.
- To investigate the diagnostic and therapeutic approaches employed in Austrian clinical centers for PCD.
- To characterize the clinical symptoms observed in children diagnosed with PCD.
Main Methods:
- A questionnaire survey was distributed to all Austrian pediatric respiratory units as part of the European Respiratory Society (ERS) task force on PCD.
- Data on patient numbers, diagnostic methods, and treatments were collected.
- Clinical data from 13 PCD patients at Vienna Children's University Hospital were analyzed for symptom description.
Main Results:
- 48 pediatric PCD patients were identified across 13 Austrian clinics, with a prevalence of 1:48,000 for ages 0-19.
- The median age at diagnosis was 4.8 years, notably lower in patients with situs inversus.
- Diagnosis commonly involved screening tests like the saccharine test and confirmation via electron microscopy, though practices varied significantly.
- Treatment for exacerbations was consistent, but other therapies and diagnostic tests showed considerable inconsistency among hospitals.
- Common symptoms included abundant respiratory secretions, recurrent infections, bronchiectasis, and bronchitis.
Conclusions:
- Significant heterogeneity exists in the diagnosis and treatment of Primary Ciliary Dyskinesia (PCD) across Austria.
- There is a need for prospective studies to better understand the disease's natural course.
- Further research is required to evaluate the efficacy and safety of various treatment strategies for pediatric PCD.
Introduction:
Primary ciliary dyskinesia (PCD) is a rare hereditary recessive disease with symptoms of recurrent pneumonia, chronic bronchitis, bronchiectasis, and chronic sinusitis. Chronic rhinitis is often the presenting symptom in newborns and infants. Approximately half of the patients show visceral mirror image arrangements (situs inversus). In this study, we aimed 1) to determine the number of paediatric PCD patients in Austria, 2) to show the diagnostic and therapeutic modalities used in the clinical centres and 3) to describe symptoms of children with PCD.
Patients, Material And Methods:
For the first two aims, we analysed data from a questionnaire survey of the European Respiratory Society (ERS) task force on Primary Ciliary Dyskinesia in children. All paediatric respiratory units in Austria received a questionnaire. Symptoms of PCD patients from Vienna Children's University Hospital (aim 3) were extracted from case histories.
Results:
In 13 Austrian clinics 48 patients with PCD (36 aged from 0-19 years) were identified. The prevalence of reported cases (aged 0-19 yrs) in Austria was 1:48000. Median age at diagnosis was 4.8 years (IQR 0.3-8.2), lower in children with situs inversus compared to those without (3.1 vs. 8.1 yrs, p = 0.067). In 2005-2006, the saccharine test was still the most commonly used screening test for PCD in Austria (45%). Confirmation of the diagnosis was usually by electron microscopy (73%). All clinics treated exacerbations immediately with antibiotics, 73% prescribed airway clearance therapy routinely to all patients. Other therapies and diagnostic tests were applied very inconsistently across Austrian hospitals. All PCD patients from Vienna (n = 13) had increased upper and lower respiratory secretions, most had recurring airway infections (n = 12), bronchiectasis (n = 7) and bronchitis (n = 7).
Conclusion:
Diagnosis and therapy of PCD in Austria are inhomogeneous. Prospective studies are needed to learn more about the course of the disease and to evaluate benefits and harms of different treatment strategies.
