/objective: There are no large, multi-centre studies of Australians with bronchiectasis. The Australian Bronchiectasis Registry (ABR) was established in 2015 to create a longitudinal research platform. We aimed to describe the baseline characteristics of adult ABR participants and assess the impact of disease severity and exacerbation phenotype on quality of life (QoL).
Key findings of this national survey of non-cystic fibrosis bronchiectasis epidemiology were that its prevalence, incidence and mortality have all increased over recent years; we estimate that around 212,000 people are currently living with bronchiectasis in the UK, very much higher than commonly quoted figures. Bronchiectasis is more common in females than males; 60% of diagnoses are made in the over-70 age group. Regional differences in prevalence, incidence, mortality, and hospital admission were identif...
Objective assessment of symptoms in bronchiectasis is important for research and in clinical practice. The COPD Assessment Test (CAT) is a short, simple assessment tool widely used in chronic obstructive pulmonary disease (COPD). The items included in the CAT are not specific to COPD and also reflect the dominant symptoms of bronchiectasis. We therefore performed a study to validate the CAT as an outcome measure in bronchiectasis.
Bronchiectasis is an increasingly recognised respiratory condition with limited therapeutic options and a complex spectrum of clinical manifestations that invariably includes chronic cough. As the primary presentation of bronchiectasis in most cases, chronic cough and its mechanistic underpinnings are of central importance but remain poorly understood in this setting. Bronchiectasis is also increasingly identified as an underlying cause of chronic cough highlighting the interrelationship between the two con...
Chronic rhinosinusitis (CRS) is associated with bronchiectasis; however, this relationship has not been well studied in the United States (US) population. In this work we aimed to determine the prevalence of CRS among patients with bronchiectasis affiliated with a US tertiary medical center and identify which comorbid diseases are associated with the presence of CRS in patients with bronchiectasis.
Quality of life (QoL) is known to be impaired in patients with bronchiectasis, which is generally attributed to exacerbations and chronic pulmonary symptoms. The aim of this study was to determine if aetiology and disease severity are associated with QoL in bronchiectasis.
Pseudomonas aeruginosa is one of the most common pathogens isolated from respiratory tract specimen in patients with bronchiectasis which is considered highly responsible for pathogenicity, progression and clinical outcomes of bronchiectasis.
Bronchiectasis is associated with morbidity, low exercise capacity and poor quality of life. There is a paucity of data on exercise capacity using cardiopulmonary exercise test (CPET) in non-cystic fibrosis (CF) bronchiectasis. Our aim was to compare exercise capacity using CPET in CF and non-CF bronchiectasis patients.
: Bronchiectasis is increasingly recognised as a major cause of morbidity and mortality worldwide. It affects children of all ethnicities and socioeconomic backgrounds and represents a far greater burden than cystic fibrosis (CF). Bronchiectasis often begins in childhood and the radiological changes can be reversed, when mild, with optimal management. As there are limited paediatric studies in this field, current treatment approaches in children are based largely upon adult and/or CF studies. The recent est...
About 25% of the patients with bronchiectasis are likely to develop a chronic colonization with Pseudomonas aeruginosa. A better understanding of predictors of acquiring Pseudomonas within the patient population may facilitate future focused research. The aim of this retrospective observational study was to investigate predicting factors for P. aeruginosa colonization in patients with bronchiectasis. This was a single-center retrospective cohort study using a bronchiectasis database which consisted of 211 p...
We compared the anti-inflammatory effects of phosphodiesterase type 4 (PDE4) inhibitor roflumilast with CHF6001, a novel PDE4 inhibitor designed for inhaled administration, using human alveolar macrophages (AM) and lung tissue explants models.
Pseudomonas aeruginosa could acquire a mucoid phenotype due to mutations in mucA (mucoid Pseudomonas aeruginosa - mPA) that is a hallmark of poor prognosis in patients with bronchiectasis. Despite the higher prevalence of Pseudomonas aeruginosa in bronchiectasis, how mPA and non-mucoid Pseudomonas aeruginosa (non-mPA) phenotypes could affect viscoelastic properties of sputum is unknown. Our aim was to determine the relationship between Pseudomonas aeruginosa phenotypes isolation, the viscoelastic properties...
Non cystic fibrosis bronchiectasis (NCBE) is an increasingly recognized chronic, progressive respiratory disorder with significant morbidity also in children and adolescents.
The term bronchiectasis describes a complex and heterogeneous clinical syndrome which can be characterized by chronic respiratory symptoms and permanent dilation of the airways due to multiple causes. Understanding what "complex" and "heterogeneous" precisely means in the context of bronchiectasis disease is challenging. Complexity means that bronchiectasis has several components with "nonlinear dynamic interactions", whereas Heterogeneity indicates that not all the potential components that define bronchie...
In this retrospective study we evaluated the demographic and clinical characteristic of adult Aboriginal Australian patients with a clinical diagnosis of COPD with and without bronchiectasis from the remote communities of the Northern Territory of Australia.
Severe asthma and bronchiectasis are heterogeneous diseases that contribute to disability beyond the pulmonary system. The magnitude of the impact that these extrapulmonary features has on health-related quality of life (HRQoL) is unknown.
We aimed to evaluate the coping styles and social support perceived by the children with two different chronic diseases (cancer and bronchiectasis), their mothers' coping styles and compare them with a control group without any chronic physical or psychiatric disorder.
a)We conducted a review of the current evidence relating to antibiotic duration in the short and long-term management of non-cystic fibrosis bronchiectasis.
Neutrophil elastase (NE) is a crucial marker of neutrophilic inflammation. We aimed to compare different techniques to detect active NE in sputum samples of 50 Bronchiectasis (BE) and 50 Cystic Fibrosis (CF) patients. Three methods including a ProteaseTag® Active NE Immunoassay (ELISA) and two enzymatic digestion assays (chromogenic -CS- and fluorogenic -FS- substrate) were compared. Results of active NE were also correlated with clinical data. The three methods provided statistically different values for ...
Non-cystic fibrosis bronchiectasis (NCFB) is characterized by airway mucus accumulation and sputum production, but the role of mucus concentration in the pathogenesis of these abnormalities has not been characterized.
Health-related Quality of Life (QoL) is one of the most important endpoints in bronchiectasis (BE). However, the majority of HRQoL questionnaires are time-consuming or not validated in BE. The COPD Assessment Test (CAT) in an easy-to-use questionnaire. The objective of this study was to perform a complete validation of CAT in BE.
Mucociliary clearance is a main defense mechanism of the airway and is impaired in ciliary dyskinesia. The objective of this study was to evaluate the prevalence of chronic rhinosinusitis (CRS) and its characteristics in bronchiectasis patients suspected of harboring ciliary dyskinesia.
The recently published guidelines of the Spanish Society of Pulmonology and Thoracic Surgery encourage physicians to use outpatient antimicrobial therapy to treat exacerbations in patients with non-cystic fibrosis bronchiectasis (NCFB). The published literature on this topic, however, is scarce.
Plasma drug concentrations, spectrum of antibacterial activity and minimum inhibitory concentration (MIC) had been widely considered as markers of the efficacy of antibiotics. Nonetheless, in several cases, antibiotics characterized by all these features were ineffective for the treatment of respiratory tract infections. A typical paradigm represented the case of patients with non-CF bronchiectasis who do not always benefit from antibiotics and thus experiencing increased sputum production, worse quality of...
