(aka Immotile Cilia Syndrome)
Epidemiology
- Autosomal recessive
- Prevalence: 1 in 15,000-30,000
- Some cases may actually be acquired (not clear at this time)
Etiology
- Classification of Types:
1) Kartagener’s Syndrome (50% of Primary Ciliary Dyskinesia cases): situs inversus totalis + sinusitis or nasal polyps + sterility + bronchiectasis
2) Sinusitis + Bronchiectasis (25% of cases):
Physiology
- Dysfunctional ciliary motility due to loss of dynein arms
Diagnosis
- PFT’s: mild-moderate obstruction
CXR/Chest CT Patterns:
1) Bronchiectasis:
2) Situs Inversus: 50% have situs inversus totalis
3)
Nasal Mucosal Bx: reveals dysfunctional cilia
Clinical
- Lung Involvement:
1) Bronchiectasis: 50% have clinically significant bronchiectasis
2) Recurrent Pulmonary Infection:
-Other SIte Involvement:
1) Situs inversus (50%): note that onyl 25% ofpatienst with situs inversus will have ciliary dysmotility and bronchiectasis
2) Situs ambiguous: switched ab-dominal contents (gastric bubble appears under right HD) with normal heart position
2) Male sterility:
3) Recurrent sinusitis:
