Primary immunodeficiency disorders (PIDs) are caused by 1 or more defects of the immune system. Patients are more likely to experience recurrent and/or severe infections and tend to develop a wide range of complications. Respiratory diseases are the main and initial manifestation in most cases and the most common complication. Pulmonary complications cause significant morbidity and mortality in patients with PIDs. Early diagnosis and appropriate treatment can prevent or at least slow the development of respiratory complications. Since the spectrum of pulmonary complications in PIDs is broad, we divided pulmonary complications into upper respiratory complications (eg, sinusitis, otitis media, and laryngeal angioedema) and lower respiratory complications (eg, pneumonia, bronchitis, bronchiectasis, interstitial lung diseases, organizing pneumonia, pulmonary adenopathies and malignancies, hyperreactive airway diseases, pulmonary dysgenesis, and adverse reactions to treatment). This review covers the main respiratory manifestations in patients with PIDs.
