Bronchiectasis is a pathologic description of lung damage characterized by inflamed and dilated thick-walled bronchi. These findings may result from a number of possible causes and these may influence treatment and prognosis. The aim of this study was to determine causative factors in 150 adults with bronchiectasis (56 male, 94 female) identified using high-resolution computerized tomography. Relevant factors were identified in the clinical history; cystic fibrosis gene mutation analysis was performed; humoral immune defects were determined by measuring immunoglobulins, IgG subclasses and functional response to Pneumovax II vaccine; assessment was made of neutrophil function (respiratory burst, adhesion molecule expression, and chemotaxis); ciliary function was observed and those likely to have allergic bronchopulmonary aspergillosis (ABPA) were identified. Causes identified were: immune defects (12 cases), cystic fibrosis (4), Young's syndrome (5), ciliary dysfunction (3), aspiration (6), panbronchiolitis (1), congenital defect (1), ABPA (11), rheumatoid arthritis (4), and early childhood pneumonia, pertussis, or measles (44). Intensive investigation of this population of patients with bronchiectasis led to identification of one or more causative factor in 47% of cases. In 22 patients (15%), the cause identified had implications for prognosis and treatment.

The majority of bronchial and interstitial diseases of the adult are accompanied by bronchiolar inflammation, but over time the use of the term "bronchiolitis" has been limited to a few specific affections. Bronchiolitis with predominantly alveolar involvement Some "bronchiolites" emphasize the problem of an interstitial pneumopathy, since the disease predominantly involves the alveolar spaces. Only a few bronchiolites are severely damaging: bronchiolitis obliterans with organizing pneumonia and interstitial pneumopathy with respiratory bronchiolitis. These predominantly alveolar affections reveal the clinical (crepitant rales), radiographic (multiple or even diffuse opacities), and functional aspects (restrictive ventilation problems). Brochiolitis with obstructive airway problems In this case the disease predominantly involves the bronchioles and spares the alveolar tissue. The term "bronchiolitis" is in this case perfectly justified. The clinical picture is evocative with obstructed airway and a clear pulmonary parenchyma on the thoracic x-ray. These affections belong to the obstructive broncho-pneumopathy group. The prototype is brochiolitis obliterans, the anatomic correlation of which is generally constrictive bronchiolitis obliterans. Occasionally primitive, it frequently complicates the progression of many morbid states (transplants, collagenosis, inhaled or ingested toxic substances.). Diffuse panbronchiolitis Other "bronchiolites" deviate from this framework and are accompanied by marked lesions of other respiratory tracts (membrane bronchioles, cartilage bronchi, mucosa, ear nose and throat). The prototype is panbronchiolitis, described in the Far East. It is exceptional in Europe, where similar but nosologically different clinical aspects are observed during various diseases: cystic fibrosis, Young's syndrome, hypogammaglobulinemia, bone marrow transplant, context of HIV or haemorrhagic recto-colitis.
