Special Issue Information

Dear Colleagues,

A cough is one of the most common complaints in outpatients, and it presents a particularly substantial burden for children and their families. Coughing has diverse and, often, multiple causes. Clinical experience has shown that the cause and pathogenesis of coughing have changed over time from the onset. The most common cause of coughing is upper respiratory tract infection, which usually remits spontaneously. However, the common cold may trigger the appearance of previously asymptomatic asthma, or the exacerbation of chronic obstructive pulmonary disease.

The impact of the COVID-19 pandemic on the identification of coughing may have led to delays in diagnosis, such as refraining from respiratory function tests and consultations. In clinical practice, misdiagnosis is not uncommon. This Special Issue will focus on new insights into coughing from various perspectives with a focus on children and how this associates with future lung health. We look forward to receiving your contributions.

In children and adults, chronic cough is a common symptom presenting to health professionals worldwide. It is internationally accepted that children with chronic cough should be managed with pediatric specific management guidelines. The newly proposed clinical entity of ‘cough hypersensitivity syndrome’ has gained significant attention in adult literature. Given the significant differences between childhood and adult chronic cough, including in respiratory physiology and anatomy, and cough sensitivity, we address the suitability of the use of cough hypersensitivity syndrome in children. We explore these differences between childhood and adult chronic cough, explain what cough hypersensitivity is and highlight why the term cough hypersensitivity syndrome should not be used in children.

The complex nature of chronic bronchitis (CB) and changing definitions have contributed to challenges in understanding its aetiology and burden. In children, CB is characterised by persistent airway inflammation often linked to bacterial infections and is therefore termed “protracted bacterial bronchitis” (PBB). Longitudinal studies suggest that CB in childhood persists into adulthood in a subgroup. It can also be associated with future chronic respiratory diseases including asthma, bronchiectasis, and chronic obstructive pulmonary disease (COPD). Adult CB is traditionally associated with smoking, occupational exposures, and lower socioeconomic status. The interplay between risk factors, childhood CB, adult CB, and other chronic respiratory diseases is intricate, requiring comprehensive longitudinal studies for a clearer understanding of the natural history of CB across the lifespan. Such longitudinal studies have been scarce to date given the logistic challenges of maintaining them over time. In this review, we summarise current evidence on the evolution of the definitions, pathophysiology, risk factors, and consequences of childhood and adulthood chronic bronchitis. Full article

Chronic wet cough for longer than 4 weeks is a hallmark of chronic suppurative lung diseases (CSLD), including protracted bacterial bronchitis (PBB), and bronchiectasis in children. Severe lower respiratory infection early in life is a major risk factor of PBB and paediatric bronchiectasis. In these conditions, failure to clear an underlying endobronchial infection is hypothesised to drive ongoing inflammation and progressive tissue damage that culminates in irreversible bronchiectasis. Historically, the microbiology of paediatric chronic wet cough has been defined by culture-based studies focused on the detection and eradication of specific bacterial pathogens. Various ‘omics technologies now allow for a more nuanced investigation of respiratory pathobiology and are enabling development of endotype-based models of care. Recent years have seen substantial advances in defining respiratory endotypes among adults with CSLD; however, less is understood about diseases affecting children. In this review, we explore the current understanding of the airway microbiome among children with chronic wet cough related to the PBB–bronchiectasis diagnostic continuum. We explore concepts emerging from the gut–lung axis and multi-omic studies that are expected to influence PBB and bronchiectasis endotyping efforts. We also consider how our evolving understanding of the airway microbiome is translating to new approaches in chronic wet cough diagnostics and treatments. Full article

A cough is one of several defensive responses that protect and clear the airways of inhaled, aspirated or locally produced chemicals and matter. The neural components needed to initiate a cough begin to develop in utero, and at birth the airways and lungs already have a rich supply of sensory and motor-neural innervation. However, a cough is not always the primary defensive response to airway challenge in very young infants, but instead develops in the first postnatal months and matures further into puberty. Consequently, the clinical presentation of a troublesome cough in children may not be the same as in adults, exemplified by important differences in cough sensitivity and hypersensitivity between children and adults. This review will summarise key anatomical and functional concepts in airway neurobiology that may improve understanding of coughs in children. Full article
