Brief Summary:
Bronchiectasis is defined as abnormal chronic dilatation of one or more bronchi. Patients have a structural abnormality of the bronchial wall that predisposes them to bacterial infection likely due to impaired mucus clearance. A vicious cycle of chest infections and chronic lung inflammation can lead to further damage of the bronchial wall and spread of disease to normal areas of bystander lung.

Condition or disease Intervention/treatment
Bronchiectasis Combination Product: Pulmonary function tests,Bronchiectasis severity index score

Detailed Description:

A search for an underlying cause, which may be amenable to a targeted intervention to prevent ongoing damage, is essential but often fruitless, and the focus of therapy rapidly turns to empiric treatments to prevent infective exacerbations and retard disease progression. The British Thoracic Society Bronchiectasis management guidelines provide an in-depth summary of the available literature and are an excellent tool for guiding treatment decision making. However, they do not provide guidance on which patients are most likely to benefit from specific interventions.Disease severity in bronchiectasis is hard to define. Radiological severity grading scores exist; however, there is often a disconnect between radiological severity, symptom burden and disease progressionIn 2014, competing bronchiectasis severity scores were published (FACED and the Bronchiectasis Severity Index (BSI).

In each of these, a combination of patient demographics, symptom scores, comorbidities, and clinical, radiological and microbiological parameters were used to construct scoring systems.

In case of the BSI, it predicted future mortality, and in the case of FACED, extended to prediction of future exacerbation frequency, hospitalisation and quality of life.These severity scores have utility in identifying an individual's risk of disease progression to a predefined outcome and aid in sub classifying this heterogeneous group of patients in a manner that may pave the way to future mechanistic studies, which explain how these different disease phenotypes arise and inform the development of targeted therapeutics.

Actual Study Completion Date : January 1, 2019

Intervention Details:
  • Combination Product: Pulmonary function tests,Bronchiectasis severity index score

    Pulmonary function tests: including spirometry, DLCO, and lung volumes. Sputum investigations: The following investigations will be performed on fresh sputum samples; gram stains and culture, smear and culture for mycobacteria and fungi and antibiotic sensitivity tests Bronchoscopy: Bronchoscopy with bronchoalveolar lavage will be used to obtain specimens for staining and culture to identify type of colonization.

    Radiology: All patients will have a chest radiograph (PA and lateral) and high-resolution computed tomography (HRCT) scan.

    Bronchiectasis severity index score parameters FACED Score

Primary Outcome Measures :
  1. ( Severity of Bronchiectasis will be measured according to BSI scoring system and FACED scoring system [ Time Frame: Baseline ]

    BSI (Bronchiectasis severity index) score parameters include: Age, Body mass index, %FEV1 predicted, Previous Hospital admissions, Number of exacerbations in previous year, MRC dyspnea scale, Pseudomonas colonization, colonization with other organisms and radiological severity.


    0-4 points Mild bronchiectasis 5-8points Moderate bronchiectasis 9+ points Severe bronchiectasis FACED score F - FEV1 A - Age C - Chronic colonization E - Radiological Extension D - Dyspnea


    0-2 points Mild bronchiectasis 3-4 points Moderate bronchiectasis 5-7 points Severe bronchiectasis

Secondary Outcome Measures :
  1. management of bronchectasis according to severity index [ Time Frame: Baseline ]
    we will modify treatment of bronchectasis according to different phenotypes of bronchiectasis and severity score.
