Barriers and facilitators of physical activity in children with bronchiectasis: Perspectives from children and parents

BACKGROUND

Current bronchiectasis management guidelines recommend regular physical activity but a large proportion of children with bronchiectasis do not meet public health recommendations which call for 60 min or more of moderate-to-vigorous intensity physical activity daily. Knowing the factors that influence physical activity in children with bronchiectasis is necessary for the development of effective interventions to increase physical activity in this patient group. The objective of this study was to identify facilitators and barriers to physical activity in children with bronchiectasis unrelated to cystic fibrosis (CF) from the perspectives of children and their parents.

MATERIALS AND METHODS

This was a qualitative study informed by the theoretical domains framework (TDF). Children aged 7-15 years (8.8 years, 8.4-11.0) (median, interquartile range) and parents (45.8 years, 39.7-48.3) completed separate, semi-structured interviews (n = 21). Recordings were transcribed verbatim, and barriers and facilitators related to each TDF domain deductively coded. Emergent themes were inductively derived via consensus moderation.

RESULTS

From the perspectives of children, fun with friends, organized sport and activities, and family co-participation in physical activity emerged as facilitators. Inability to keep up with their peers and time on technology emerged as barriers. From the perspectives of parents, instrumental and logistic support for physical activity and supportive social and physical activity environments emerged as facilitators, while management of symptoms associated with bronchiectasis emerged as a barrier.

CONCLUSION

Programs to increase physical activity in children with bronchiectasis should be fun, accessible, provide opportunities for social interaction and address barriers related to exercise tolerance, perceived competence, and presence of respiratory symptoms.

Burden of Care for Children with Bronchiectasis from Parents/Carers Perspective

Bronchiectasis is a neglected chronic respiratory condition. In children optimal appropriate management can halt the disease process, and in some cases reverse the radiological abnormality. This requires many facets, including parental/carer bronchiectasis-specific knowledge, for which there is currently no such published data. Further, the importance of patient voices in guiding clinical research is becoming increasingly appreciated. To address these issues, we aimed to describe the voices of parents of children with bronchiectasis relating to (a) burden of illness and quality of life (QoL), (b) their major worries/concerns and (c) understanding/management of exacerbations. The parents of 152 children with bronchiectasis (median age = 5.8 years, range 3.5-8.4) recruited from the Queensland Children's Hospital (Australia) completed questionnaires, including a parent-proxy cough-specific QoL. We found that parents of children with bronchiectasis had impaired QoL (median 4.38, range 3.13-5.63) and a high disease burden with median 7.0 (range 4.0-10.0) doctor visits in 12-months. Parental knowledge varied with only 41% understanding appropriate management of an exacerbation. The highest worry/concern expressed were long-term effects (n = 42, 29.8%) and perceived declining health (n = 36, 25.5%). Our study has highlighted the need for improved education, high parental burden and areas of concern/worry which may inform development of a bronchiectasis-specific paediatric QoL tool.

A "pretty normal" life: a qualitative study exploring young people's experience of life with bronchiectasis

PURPOSE

Bronchiectasis is a chronic respiratory disease that impacts significantly on quality of life for those who have it. There is a paucity of literature exploring the perspectives of children and young people. The aim of this study was to examine the day-to-day life experience of a group of young people with bronchiectasis.

METHOD

A qualitative study using semi-structured interviews explored fifteen young people's perspectives of life with bronchiectasis. Key themes were identified using an inductive iterative approach through constant comparative analysis guided by Thorne's interpretive description.

RESULTS

Life with bronchiectasis was conceptualized by participants as "Pretty Normal". This consisted of two co-existing life views which represented how young people balanced the ups and downs of adolescence while learning to accommodate the demands of living with bronchiectasis. Three key thematic elements "sore and tired", 'life interrupted and "looking after self", influenced and challenged these two views of life.

CONCLUSIONS

Young people with bronchiectasis portray life as being the same as their peers. Despite this, they recognized that the symptoms, interruptions, and self-management responsibilities led them to find ways of coping and integrating their experience into a new and modified view of normal.

Pathogenesis and Treatment of Refractory Disease Courses in Systemic Juvenile Idiopathic Arthritis: Refractory Arthritis, Recurrent Macrophage Activation Syndrome and Chronic Lung Disease

Systemic juvenile idiopathic arthritis is a distinct and heterogeneous disease presently classified under the umbrella of juvenile idiopathic arthritis, with some patients following a monophasic remitting course, whereas others have persistent disease with chronic organ- and life-threatening complications. Although biologic therapies have revolutionized treatment, recent follow-up studies report significant numbers of children with persistently active disease on long term follow-up. This review focuses on refractory disease courses, specifically refractory arthritis, systemic juvenile idiopathic arthritis with recurrent, or longstanding signs of macrophage activation syndrome, and systemic juvenile idiopathic arthritis associated with suspected, probable, or definite lung disease.

Factors associated with "Frequent Exacerbator" phenotype in children with bronchiectasis: The first report on children from the Australian Bronchiectasis Registry

INTRODUCTION

In adults with bronchiectasis, multicentre data advanced the field including disease characterisation and derivation of phenotypes such as 'frequent exacerbator (FE)' (≥3 exacerbations/year). However, paediatric cohorts are largely limited to single centres and no scientifically derived phenotypes of paediatric bronchiectasis yet exists. Using paediatric data from the Australian Bronchiectasis Registry (ABR), we aimed to: (a) describe the clinical characteristics and compare Indigenous with non-Indigenous children, and (b) determine if a FE phenotype can be identified and if so, its associated factors.

METHODS

We retrieved data of children (aged <18-years) with radiologically confirmed bronchiectasis, enrolled between March 2016-March 2020.

RESULTS

Across five sites, 540 children [288 Indigenous; median age = 8-years (IQR 6-11)] were included. Baseline characteristics revealed past infection/idiopathic was the commonest (70%) underlying aetiology, most had cylindrical bronchiectasis and normal spirometry. Indigenous children (vs. non-Indigenous) had significantly more environmental tobacco smoke exposure (84% vs 32%, p < 0.0001) and lower birth weight (2797 g vs 3260 g, p < 0.0001). FE phenotype present in 162 (30%) children, was associated with being younger (OR_adjusted = 0.85, 95%CI 0.81-0.90), more recent diagnosis of bronchiectasis (OR_adjusted = 0.67; 95%CI 0.60-0.75), recent hospitalization (OR_adj = 4.51; 95%CI 2.45-8.54) and Pseudomonas aeruginosa (PsA) infection (OR_adjusted = 2.43; 95%CI 1.01-5.78). The FE phenotype were less likely to be Indigenous (OR_adjusted = 0.14; 95%CI 0.03-0.65).

CONCLUSION

Even within a single country, the characteristics of children with bronchiectasis differ among cohorts. A paediatric FE phenotype exists and is characterised by being younger with a more recent diagnosis, PsA infection and previous hospitalization. Prospective data to consolidate our findings characterising childhood bronchiectasis phenotypes are required.

Noncystic fibrosis bronchiectasis in children and adolescents: Follow-up over a decade

BACKGROUND

Noncystic fibrosis bronchiectasis (NCFB) is still considered an "orphan disease" in pediatric age.

OBJECTIVE

The study describes the clinical and functional features, the instrumental, and microbial findings of a large cohort of patients with NCFB, followed in a single tertiary level hospital.

METHODS

Children and adolescents diagnosed with NCFB from January 1, 2010 to December 31, 2019 were included. Data from the diagnosis and during the years of follow-up were recorded retrospectively.

RESULTS

One hundred and thirty-eight patients were enrolled. The most common cause of NCFB was postinfectious (33%), followed by primary ciliary dyskinesia (PCD) (30%), esophageal atresia (EA) (9.5%), and secondary immunodeficiency (9.5%). Chronic cough was the most frequent symptom. The median age of symptoms presentation was 3 years (interquartile age [IQR]: 12-84), with a precocious onset in PCD and EA groups. The median age of CT diagnosis was 9 years for all groups but PCD patients who were diagnosed at older age. Lingula, medium, upper, and lower lobes were more involved in PCD group, while diffuse distribution was observed in the postinfectious one. Microbial exams showed Pseudomonas aeruginosa colonization higher in PCD patients (22%). Despite microbial differences in airways colonization, no difference in respiratory exacerbation rate was recorded among groups. Lung function tests demonstrated the stability of forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) over time, except for the secondary immunodeficiency group.

CONCLUSIONS

The role of infections in developed countries should not be underestimated and a major effort to obtain an earlier identification of bronchiectasis should be taken. A prompt diagnosis of NFCB could help to reduce the frequency of exacerbations and improve the stability of lung function over time.

Imaging in non-cystic fibrosis bronchiectasis and current limitations

Non-cystic fibrosis bronchiectasis represents a heterogenous spectrum of disorders characterised by an abnormal and permanent dilatation of the bronchial tree associated with respiratory symptoms. To date, diagnosis relies on computed tomography (CT) evidence of dilated airways. Nevertheless, definite radiological criteria and standardised CT protocols are still to be defined. Although largely used, current radiological scoring systems have shown substantial drawbacks, mostly failing to correlate morphological abnormalities with clinical and prognostic data. In limited cases, bronchiectasis morphology and distribution, along with associated CT features, enable radiologists to confidently suggest an underlying cause. Quantitative imaging analyses have shown a potential to overcome the limitations of the current radiological criteria, but their application is still limited to a research setting.

In the present review, we discuss the role of imaging and its current limitations in non-cystic fibrosis bronchiectasis. The potential of automatic quantitative approaches and artificial intelligence in such a context will be also mentioned.

Clinical and research priorities for children and young people with bronchiectasis: an international roadmap

The global burden of children and young people (CYP) with bronchiectasis is being recognised increasingly. They experience a poor quality of life and recurrent respiratory exacerbations requiring additional treatment, including hospitalisation. However, there are no published data on patient-driven clinical needs and/or research priorities for paediatric bronchiectasis.

Parent/patient-driven views are required to understand the clinical needs and research priorities to inform changes that benefit CYP with bronchiectasis and reduce their disease burden. The European Lung Foundation and the European Respiratory Society Task Force for paediatric bronchiectasis created an international roadmap of clinical and research priorities to guide, and as an extension of, the clinical practice guideline.

This roadmap was based on two global web-based surveys. The first survey (10 languages) was completed by 225 respondents (parents of CYP with bronchiectasis and adults with bronchiectasis diagnosed in childhood) from 21 countries. The parent/patient survey encompassed both clinical and research priorities. The second survey, completed by 258 health practitioners from 54 countries, was limited to research priorities.

The two highest clinical needs expressed by parents/patients were: having an action management plan for flare-ups/exacerbations and access to physiotherapists. The two highest health practitioners’ research priorities related to eradication of airway pathogens and optimal airway clearance techniques. Based on both surveys, the top 10 research priorities were derived, and unanimous consensus statements were formulated from these priorities.

This document addresses parents'/patients' clinical and research priorities from both the parents'/patients' and clinicians' perspectives and will help guide research and clinical efforts to improve the lives of people with bronchiectasis.

Increased mortality in patients with non cystic fibrosis bronchiectasis with respiratory comorbidities

There are limited data regarding whether mortality is higher in patients with non cystic fibrosis bronchiectasis (bronchiectasis) than in those without bronchiectasis. Using 2005-2015 data from the Korean National Health Insurance Service, we evaluated hazard ratio (HR) for all-cause mortality in the bronchiectasis cohort relative to the matched cohort. The effect of comorbidities over the study period on the relative mortality was also assessed. All-cause mortality was significantly higher in the bronchiectasis cohort than in the matched cohort (2505/100,000 vs 2142/100,000 person-years, respectively; P < 0.001). Mortality risk was 1.15-fold greater in the bronchiectasis cohort than in the matched cohort (95% confidence interval [CI] 1.09-1.22); mortality was greatest among elderly patients (HR = 1.17, 95% CI 1.10-1.25) and men (HR = 1.19, 95% CI 1.10-1.29). Comorbidities over the study period significantly increased the risk of death in the bronchiectasis cohort relative to the matched cohort: asthma (adjusted HR = 1.20, 95% CI 1.11-1.30), chronic obstructive pulmonary disease (adjusted HR = 1.24, 95% CI 1.15-1.34), pneumonia (adjusted HR = 1.50, 95% CI 1.39-1.63), lung cancer (adjusted HR = 1.85, 95% CI 1.61-2.12), and cardiovascular disease (adjusted HR = 1.34, 95% CI 1.23-1.45). In contrast, there were no significant differences in the risk of death in patients without bronchiectasis-related comorbidities and the matched cohort, except in the case of non-tuberculous mycobacterial infection. In conclusion, all-cause mortality was higher in patients with bronchiectasis cohort than those without bronchiectasis, especially in elderly patients and men. Comorbidities over the study period played a major role in increasing mortality in patients with bronchiectasis relative to those without bronchiectasis.
