    Residual lung abnormality following COVID-19 hospitalisation is characterised by biomarkers of epithelial injury

    , EBioMedicine, ISSN: 2352-3964

    Some survivors of acute COVID-19 infection have long-term symptoms that could suggest ongoing lung impairment. Searches performed in MEDLINE and Embase for SARS-COV-2 studies with radiological lung follow-up estimated that 50% of participants had inflammatory patterns and 29% had fibrotic patterns at a median of 3 months post infection. Analysis of the UK nationwide Post-hospitalisation COVID-19 Study at 5-months follow-up suggested that up to 11% of people discharged from hospital following COVID-19 infection were at-risk of radiological residual lung abnormalities, such as ground glass opacity and reticulation. In people with pulmonary fibrosis, these radiological patterns are often consistent with persistent epithelial lung injury. Biomarker studies have identified associations with COVID-19 severity, however there are few studies that explore the relationship between biomarkers of epithelial injury and parenchymal lung abnormalities post-hospitalisation.

    A Prospective Study of Fibrosis in the Lung Endpoints (PROFILE): characteristics of an incident cohort of patients with idiopathic pulmonary fibrosis

    , BMJ Open Respiratory Research, ISSN: 2052-4439

    Background: Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive fibrotic lung disease. The PROFILE study was a prospective, observational cohort study designed to better define the natural history of IPF, understand disease biology and identify biomarkers to support disease management and enhance clinical trial design.Methods: Individuals with an incident diagnosis of IPF were recruited between 2010 and 2017 across two co-ordinating centres in the UK. Demographics, clinical measurements and blood samples were obtained at baseline, and 1, 3, 6, 12, 24, 36 months. Disease progression events were defined as death or relative FVC decline>10% at 12 months. Survival estimates were modelled using cox proportional hazards; longitudinal lung function decline was estimated using mixed effect models, specified with restricted cubic splines, a random intercept for participant and random effect for study visit. All models were adjusted for baseline age, sex and continuous baseline percent predicted forced vital capacity (ppFVC).Results: A total of 632 participants were recruited, 77.1% were male and mean age at enrolment was 70.4 years (SD 8.4). Mean baseline ppFVC was 79.5% (SD 19.2), mean percent predicted DLCO (ppDLCO) was 45.7% (SD 15.1). A total of 304 (48.1%) participants met disease progression criteria at 1 year. Median survival was 3.7 years (95%CI 3.3; 4.0). More severe baseline physiology, 12-month relative lung function decline ≥10%, older age, and short telomeres were independent risk factors for mortality. Twelve-month estimated change in ppFVC was -5.28% (95%CI -6.34; -4.22) with an average FVC decline of 186.9ml (95%CI -225.4.0; -148.5), 12-month estimated change in ppDLCO was -3.35% (95%CI -4.30; -2.40).Conclusion: The PROFILE cohort confirms that untreated, IPF is inexorable progressive and inevitably fatal with a poor median survival from diagnosis.

    Detecting Small Airways Dysfunction in Asthma: Rationale, Findings, and Future of ATLANTIS.

    , J Allergy Clin Immunol Pract, Vol: 14, Pages: 56-66

    Small airway dysfunction (SAD) is both common and clinically relevant in patients with asthma. However, there is no recognized "gold standard" approach for the identification of SAD in clinical practice. The ATLANTIS (AssessmenT of smalL Airways involvemeNT In aSthma) study was a prospective (1-year follow-up), multicenter, international observational study that aimed to identify the best, or best combination of biomarkers, physiological tests, and imaging markers for the determination of the presence of SAD, and to evaluate the contribution of SAD across all asthma severities to meaningful clinical asthma outcomes. A large number of analyses from the ATLANTIS study have been conducted or are planned. This narrative review summarizes the key findings to date and the future directions. Perhaps the most important finding so far is that a "toolbox" of spirometry, oscillometry, and a small airways dysfunction questionnaire can detect SAD with high accuracy (area under the receiver operating characteristic curve 0.96 and positive likelihood ratio 12.8). Further, collaboration with other consortia has demonstrated the use of oscillometry to identify asthma phenotypes. We advocate the adoption of the ATLANTIS toolbox into interventional studies in asthma-and if validated, this could form a useful part of research and daily clinical practice.

    Exploring geographic differences in IgE response through network and manifold analyses.

    , J Allergy Clin Immunol, Vol: 157, Pages: 262-272

    BACKGROUND: Component-resolved diagnostics allow detailed assessment of IgE sensitization to multiple allergenic molecules (component-specific IgEs, or c-sIgEs) and may be useful for asthma diagnosis. However, to effectively use component-resolved diagnostics across diverse settings, it is crucial to account for geographic differences. OBJECTIVE: We investigated spatial determinants of c-sIgE networks to facilitate development of diagnostic algorithms applicable globally. METHODS: We used multiplex component-resolved diagnostics array to measure c-sIgE to 112 proteins in an international collaboration of several studies: WASP (World Asthma Phenotypes; United Kingdom, New Zealand, Brazil, Ecuador, and Uganda), U-BIOPRED (Unbiased Biomarkers for the Prediction of Respiratory Disease Outcomes; 7 European countries), and MAAS (Manchester Asthma and Allergy Study, a UK population-based birth cohort). Hierarchical clustering on low-dimensional representation of co-occurrence networks ascertained sensitization and c-sigE clusters across populations. Cross-country comparisons focused on a common subset of 18 c-sIgEs. We investigated sensitization networks across regions in relation to asthma severity. RESULTS: Sensitization profiles shared similarities across regions. For 18 c-sIgEs shared across study populations, the response structure enabled differentiation between different geographic areas and study designs, revealing 3 clusters: (1) Uganda, Ecuador, and Brazil, (2) U-BIOPRED children and adults, and (3) New Zealand, United Kingdom, and MAAS. Spectral clustering identified differences between clusters. We observed constant, almost parallel shifts between severe and nonsevere asthma in each country. CONCLUSIONS: Patterns of c-sIgE response reflect geographic location and study design. However, despite geographic differences in c-sIgE networks, there is a remarkably consistent shift between networks of subjects with nonsevere and severe asthma.

    Looking beyond bronchopulmonary dysplasia: prematurity-associated lung disease and its phenotypes.

    , Lancet Respir Med, Vol: 14, Pages: 60-71

    Preterm birth is increasingly recognised as a determinant of chronic respiratory disease across the life course. In this Series on prematurity-associated lung disease (PLD), we introduce the concept of PLD as a unifying framework for the diverse pulmonary consequences of preterm birth. Historically, most attention has focused on extremely preterm infants (<28 weeks of gestation) who develop bronchopulmonary dysplasia (BPD), yet not all infants with BPD have long-term morbidity. Conversely, those born very (28-31 weeks), moderate (32-33 weeks), or late (34-36 weeks) preterm also have increased risk for developing lung disease. Multiple factors beyond BPD-including gestational age and intrauterine growth restriction-contribute to PLD development. Recently described PLD phenotypes include prematurity-associated obstructive lung disease, prematurity-associated preserved ratio impaired spirometry, and prematurity-associated dysanapsis. Each phenotype reflects distinct early-life exposures and mechanisms, with differing implications for prognosis. Defining these phenotypes provides a foundation for personalised monitoring and targeted therapeutic strategies.

    Exploring health professional views of management for preschool wheeze: a qualitative study.

    , Arch Dis Child

    OBJECTIVE: This study aimed to explore health professionals' perspectives on the management of preschool wheeze, including their views on using tests to guide treatment for children with recurrent wheeze. DESIGN: Purposive and snowball sampling were used in this qualitative study to recruit health professionals with experience of managing children with pre-school wheeze from primary and secondary care settings across England. Semi-structured interviews were conducted via Microsoft Teams. Transcripts were analysed thematically, supported by the use of NVivo software, to identify key themes. RESULTS: 14 health professionals participated: four general practitioners, four general paediatricians, four hospital asthma nurses, one tertiary respiratory paediatrician and one primary care nurse. Participants agreed that preschool wheeze remains a significant disease. Thematic analysis identified four key themes: (1) challenges with diagnostic terminology, where a lack of consistent terminology was considered to impact communication and management; (2) diagnostic uncertainty, where the absence of objective tests for early asthma diagnosis negatively contributed to management plans; (3) current practice of investigating children with preschool wheeze, where participants described a lack of infrastructure and approach to performing tests in primary and secondary care; and (4) treatment considerations in which parents' medication beliefs were thought to influence adherence to prescribed treatments. There were differences in the views regarding the management of preschool wheeze between primary and secondary care professionals. CONCLUSION: Health professionals' views highlight inconsistent use of diagnostic terminology for preschool wheeze, contributing to variation in management. Integrated care pathways and infrastructure are urgently needed to improve outcomes for children with preschool wheeze.

    Clustering lung function and symptom profiles for asthma risk stratification

    , Scientific Reports, ISSN: 2045-2322

    Asthma is a heterogeneous condition often studied through wheeze alone, yet the interplay between lung function and reported symptoms remains underexplored. To capture this heterogeneity, we applied Bayesian Profile Regression to data from school-age children in two prospective birth cohorts, integrating airway hyperresponsiveness, lung function, bronchodilator reversibility, allergic sensitisation, reported symptoms, and physician diagnosis. In the Manchester Allergy and Asthma Study (discovery cohort), five reproducible clusters were identified: HA-LLF (high asthma-low lung function), HA-NLF (high asthma-near-normal lung function), LA-LLF (low asthma-low lung function), LA-NLF (low asthma-normal lung function), and INT-SYM (intermediate asthma with prominent symptoms). The HA-LLF and HA-NLF clusters had very high asthma prevalence (80–100%), but differed markedly in lung function, airway responsiveness, bronchodilator reversibility, sensitisation, and symptom burden. The LA-HLF and LA-NLF clusters with low asthma prevalence (<5%) displayed contrasting lung function profiles, while INT-SYM (~50% asthma prevalence) was largely defined by prominent symptoms such as chest tightness and shortness of breath. These subtypes were replicated in an independent cohort, Isle of Wight. Our findings demonstrate that integrating physiological, immunological, and symptom-based measures yields clinically meaningful asthma subtypes beyond wheeze-based definitions and may support more precise disease classification.

    Preschool wheeze endotypes and their association with asthma attacks and ICS response

    , ERJ Open Research, ISSN: 2312-0541

    Background: Eosinophilic airway inflammation predicts asthma attacks and inhaled corticosteroid (ICS) response in adults; similar mechanisms may apply to preschool wheeze. This study assessed whether blood eosinophil count (BEC) alone or combined with allergic sensitisation and fractional exhaled nitric oxide (FeNO) was associated with future wheeze attacks. Methods: Ninety-five preschool children (aged 12-59 months) with clinician-confirmed wheeze were recruited from primary and secondary care. At baseline, finger-prick BEC, skin-prick testing for allergic sensitisation and offline FeNO were performed. Children were followed for eight-to-nine months. The primary outcome was the number of acute wheeze attacks diagnosed during unscheduled visits to an emergency department or general practitioner, documented by parental reports, medical records, or oral corticosteroid prescriptions. Exploratory analyses examined ICS association with wheeze attack odds across different biomarker subgroups. Results: Children with BEC had higher wheeze attack odds over nine months [N=60, Odds ratio (OR):4.27, 95%CI:1.7–11.38]. Odds were greatest in those with BEC and FeNO ppb (N=12, OR:60.74, 95%CI:2.98–1238.9). ICS prescription was associated with reduced three-month wheeze attack odds among children with elevated BEC (N=21, OR:0.11, 95% CI:0.02–0.49) or allergic sensitisation (N=19, OR:0.11, 95%CI:0.01–0.65), with further reduction when both were combined (N=10, OR:0.06, 95%CI:0.002–0.59). Conclusion: Elevated BEC may identify preschool children at increased wheeze attack odds, particularly when combined with FeNO. ICS treatment was associated with odd reduction in children with elevated BEC or allergic sensitisation. These findings provide rationale for future randomised controlled trials comparing biomarker-guided and symptom-based treatment strategies.
