Bronchodilator response to inhaled beta-2 agonist and anticholinergic drugs in patients with bronchiectasis.
An increase in incidence of reversible airflow obstruction and bronchial hyperresponsiveness occurs in patients with bronchiectasis. We conducted a study to assess the efficacy of bronchodilators in the treatment of bronchiectasis.. Twenty-four patients with confirmed bronchiectasis were studied. Each patient inhaled fenoterol 400 microg administered by metered dose inhaler via a spacer after a baseline lung function and a lung function test was repeated 30 min later. This was followed by a second dose of fenoterol 5 mg via nebulizer and another lung function test 30 min later. A repeat study was done at least 24 h later with ipratropium bromide 40 microg by metered dose inhaler and 500 microg by a nebulizer.. The results showed a significant improvement from baselines (mean percentage change +/- SD) of peak expiratory flow rate (PEF) by 8.5 +/- 8.72% and 15.3 +/- 11.63%, forced expiratory volume in 1 s (FEV1) by 8.77 +/- 9.69% and 10.2 +/- 12.2% and forced vital capacity (FVC) by 10.25 +/- 11.61% and 10.09 +/- 10.88% after low- and high-dose fenoterol, respectively. The improvements after low- and high-dose ipratropium bromide for PEE FEV1 and FVC were 9.89 +/- 9.35% and 14.39 +/- 12.82%, 9.38 +/- 10.41% and 13.52 +/- 17.09%, and 8.03 +/- 10.85% and 9.63 +/- 13.85%, respectively. Eleven patients (45.8%) responded to one or both bronchodilators significantly (> 15% improvement in FEV1). Five patients (20%) responded to both, three (12%) to fenoterol alone and another three (12%) to ipratropium bromide alone.. There is significant bronchodilator response in a subset of patients with bronchiectasis and patients with bronchiectasis should therefore undergo bronchodilator testing. Skin prick testing against a panel of nine allergens done on each individual yielded a positive result in 13 patients (54.2%).

High Frequency of Allergic Bronchopulmonary Aspergillosis in Bronchiectasis-COPD Overlap.
Allergic bronchopulmonary aspergillosis (ABPA) is associated with frequent exacerbations and poor outcomes in chronic respiratory disease, but remains underdiagnosed. The role of fungal sensitization in bronchiectasis-COPD overlap (BCO) is unknown.. What is the occurrence and clinical relevance of Aspergillus sensitization and ABPA in BCO when compared with individuals with COPD or bronchiectasis without overlap?. Prospective, observational, cross-sectional study.. We prospectively recruited 280 patients during periods of clinical stability with bronchiectasis (n = 183), COPD (n = 50), and BCO (n = 47) from six hospitals across three countries (Singapore, Malaysia, and Scotland). We assessed sensitization responses (as specific IgE) to a panel of recombinant Aspergillus fumigatus allergens and the occurrence of ABPA in relationship to clinical outcomes.. Individuals with BCO show an increased frequency and clinical severity of ABPA compared with those with COPD and bronchiectasis without overlap. BCO-associated ABPA is associated with more severe disease, higher exacerbation rates, and lower lung function when compared with ABPA occurring in the absence of overlap. BCO with a severe bronchiectasis severity index (BSI; > 9) is associated significantly with the occurrence of ABPA that is unrelated to underlying COPD severity.. BCO demonstrates a high frequency of ABPA that is associated with a severe BSI (> 9) and poor clinical outcomes. Clinicians should maintain a high index of suspicion for the potential development of ABPA in patients with BCO with high BSI.

Increased Chitotriosidase Is Associated With Aspergillus and Frequent Exacerbations in South-East Asian Patients With Bronchiectasis.
Chitinase activity is an important innate immune defence mechanism against infection that includes fungi. The 2 human chitinases: chitotriosidase (CHIT1) and acidic mammalian chitinase are associated to allergy, asthma, and COPD; however, their role in bronchiectasis and bronchiectasis-COPD overlap (BCO) is unknown.. What is the association between chitinase activity, airway fungi and clinical outcomes in bronchiectasis and bronchiectasis-COPD overlap?. A prospective cohort of 463 individuals were recruited across five hospital sites in three countries (Singapore, Malaysia, and Scotland) including individuals who were not diseased (n = 35) and who had severe asthma (n = 54), COPD (n = 90), bronchiectasis (n = 241) and BCO (n = 43). Systemic chitinase levels were assessed for bronchiectasis and BCO and related to clinical outcomes, airway Aspergillus status, and underlying pulmonary mycobiome profiles.. Systemic chitinase activity is elevated significantly in bronchiectasis and BCO and exceed the activity in other airway diseases. CHIT1 activity strongly predicts bronchiectasis exacerbations and is associated with the presence of at least one Aspergillus species in the airway and frequent exacerbations (≥3 exacerbations/y). Subgroup analysis reveals an association between CHIT1 activity and the "frequent exacerbator" phenotype in South-East Asian patients whose airway mycobiome profiles indicate the presence of novel fungal taxa that include Macroventuria, Curvularia and Sarocladium. These taxa, enriched in frequently exacerbating South-East Asian patients with high CHIT1 may have potential roles in bronchiectasis exacerbations.. Systemic CHIT1 activity may represent a useful clinical tool for the identification of fungal-driven "frequent exacerbators" with bronchiectasis in South-East Asian populations.

Chronic suppurative lung disease in a developing country: impact on child and parent.
To investigate the impact of chronic suppurative lung disease (CSLD) on growth and lung function in the child as well as quality of life of the child and parent.. Cross-sectional study in 60 children with CSLD, bronchiectasis (including cystic fibrosis) and bronchiolitis obliterans. Thirty-five parents were interviewed while the remaining patients' data were collated from medical notes. Anthropometric measurements at first diagnosis and at interview were compared. The most recent lung function was also collected. The Parent Cough-Specific Quality of Life (PC-QOL) and the Depression, Anxiety and Stress (DASS21) questionnaires were administered to parents.. The median (range) age at diagnosis was 1.3 (0.2-11) years. The median (IQR) duration between anthropometric measurements was 35 (15, 59) months. Children with cystic fibrosis (CF) had improvements both in weight and BMI, whereas children with non-CF CSLD had no improvements in any growth parameter. Seventy-eight percent of children who performed spirometry had values <80% of normal predicted value. PC-QOL scores were low. Frequent exacerbations (more than twice in the past 6 months) and cough (more than 2 days/week) were not associated with significantly lower PC-QOL scores. Seventy-seven percent of interviewed parents had abnormal DASS21 scores with 54% being stressed and 51% being depressed. Mental health was better in parents of children with CF.. CSLD had a negative impact on growth, lung function, and quality of life. Children with CF had a better outcome in growth as well as better parental mental health compared to children with other etiologies. Pediatr Pulmonol. 2014; 49:435-440. © 2013 Wiley Periodicals, Inc.

Clinical and high resolution computed tomography characteristics of patients with rheumatoid arthritis lung disease.
Rheumatoid arthritis (RA) is a systemic disease of unknown cause. A variety of pulmonary disorders have been described in association with RA. Among the most common are interstitial lung disease (ILD) and bronchiectasis.. This study aims to determine the characteristics of RA patients with lung disease in relation to clinical characteristics, pulmonary function test (PFT) and high resolution computed tomography (HRCT) thorax.. This is a 6-months cross-sectional study involving 63 consecutive RA patients in an outpatient rheumatology clinic. Patients had a mean disease duration of 5 years and above. Disease activity and severity was assessed by Disease Activity Score 28 (DAS28), Health Assessment Questionnaire (HAQ) and Rheumatoid Arthritis Articular Damage (RAAD) score. Full pulmonary function test (PFT) and HRCT of thorax were performed.. The prevalence of RA-ILD is 44% and 67% of patients are asymptomatic. There was significant higher proportion (68%) in patients of Chinese ethnicity who have ILD. Diffusion capacity of carbon monoxide was abnormal in all patients and forced expiratory flow (FEF)(25-75%) was low in 16%. Restrictive pattern was 66.7% by PFT. The most common HRCT findings were reticulation (46%) followed by ground glass opacities (38.1%) and bronchiectasis (28.6%). There was no association between ILD and male gender, duration of the disease, smoking, rheumatoid factor, extra-articular manifestations, disease activity or severity.
