“…Although HRCT scanning is widely used for the diagnosis of bronchiectasis (Grenier et al 1986), the subjects in this study were evaluated using conventional spiral CT because they wanted to be examined for the presence of lung cancer. Using a different CT protocol may not have detected the lesions and may have missed the cases of bronchiectasis.…”

“…Diagnosis of bronchiectasis is confirmed by high resolution computed tomography (HRCT), which is both sensitive and specific in detecting pathologically dilated bronchi (Grenier et al 1986). Therefore, we aimed to evaluate the prevalence of bronchiectasis based on computed tomography (CT) findings, the gold standard for the diagnosis of bronchiectasis, in adult subjects who underwent a health screening program and chest CT.…”

Bronchiectasis is one of the common chronic respiratory diseases and associated with respiratory morbidity and mortality. However, neither its prevalence nor its etiology is well-defined. We aimed to estimate the prevalence and risk factors of bronchiectasis in adults. In a retrospective study, we analyzed radiologic findings on chest computed tomography (CT) images performed as part of a health-screening program. From January to December 2008, 1,409 (24.6%) of 5,727 participants in the screening program of a health promotion center at a university hospital underwent chest CT scans based on the subject' s decision. Bronchiectasis was diagnosed, if there was abnormal bronchial dilatation in any area of both lungs on chest CT. Respiratory symptoms, smoking status, and past medical history were also analyzed to define clinical characteristics and risk factors of bronchiectasis. Of 1,409 patients (aged 23-86 years), who were screened for respiratory diseases using chest CT for one year in a health promotion center, 129 patients (9.1%) were diagnosed with bronchiectasis. The prevalence of bronchiectasis was higher in females than in males (11.5% vs. 7.9%, p = 0.022) and increased with age. Respiratory symptoms were reported in 53.7% of subjects. Previous history of tuberculosis (TB) (OR 4.61, 95% CI 2.39-8.88, p = 0.001) and age (OR 2.49, 95% CI 1.56-3.98, p = 0.001) were significantly associated with bronchiectasis. This retrospective analysis of chest CT findings in health screening examinees revealed a very high prevalence of bronchiectasis in adults. Previous TB infection is one of the major causes of bronchiectasis.

“…The use of thin-section CT is superior to chest radiography for the detection of bronchiectasis or mucus plugging (Naidich et al 1982;Grenier et al 1986). Evidence for airway-ectasia was found in all of our patients with DPB.…”

Summary: The usefulness of thin-section computed tomography (CT) in the identification of the specific and clinically relevant pathologic changes in airway disease has been well documented. However, this approach has not been used for objective evaluation in patients with diffuse panbronchiolitis. Therefore attempts were made to use it in patients with diffuse panbronchiolitis. The study group included 12 men and 10 women, 17 to 69 years of age (mean, 47 years) with diffuse panbronchiolitis. All patients were evaluated by thin-section CT and pulmonary function testing. The CT score was calculated by a modified score criteria. The correlations between the CT score and the pulmonary function parameters were assessed by Pearson's linar regression analysis. Bronchiolar inflammation and airway-ectasia were present in all 22 patients. Periairway thickening was present in 17 patients. Pus plugging was present in 18 patients. Two patients had bullae formation, and 6 had air-trapping. Pulmonary collapse or consolidation was evident in 6patients. The CT score demonstrated a significant negative correlation with FEV1% (r=-3.267, p=.0230), %VC (r=-4.658, p=.0018), and arterial blood oxygen concentration (r=-1.009, p=.0381). The thin-section CT findings in patients with diffuse panbronchiolitis closely resembled those in patients with cystic fibrosis, previously described. Furthermore, a CT scoring system is useful for objective evaluation of lung disease severity in patients with diffuse panbronchiolitis.

“…23,25 La prueba más sensible es la tomografía axial computarizada de alta resolución (TACAR). Su sensibilidad es del 96% y su especificidad del 93%, 58 por lo que se considera la técnica diagnóstica de elección. 23,25 El diagnóstico se establece cuando el diámetro interno bronquial es mayor que el diáme-tro externo del vaso adyacente, o bien se visualizan bronquios a menos de 1 cm de la superficie pleural.…”

RESUMENLas bronquiectasias son un problema de salud en países desarrollados y en vías de desarrollo. La fibrosis quística es una causa importante, si bien fuera de ésta existen causas que convierten a las bronquiectasias no relacionadas con fibrosis quística en un diagnóstico frecuente. Su diagnóstico precoz basado en la clínica y posterior confirmación radiológica es el punto de partida para determinar la etiología e instaurar un tratamiento dirigido a la causa subyacente. Para ello es menester una evaluación ordenada y sistemá-tica. Se presenta una revisión sobre la etiología y tratamiento de las bronquiectasias, especialmente de las no relacionadas con fibrosis quística. Palabras clave: bronquiectasias, fibrosis quística, antibióticos, infección bronquial, diagnóstico. SUMMARYBronchiectasis is still an important health problem in both, developed and developing countries. Cystic fibrosis is one of the most important causes, but a great variety of other causes makes non cystic fibrosis bronchiectasis a relatively frequent diagnosis. Early diagnosis based on medical history and radiological confirmation is only the starting point to determine the specific etiology, in order to establish a treatment focused on the underlying cause. For this purpose, an orderly and systematic diagnostic evaluation is required. A review article about bronchiectasis, particularly those not related to cystic fibrosis, is presented.
