Streptococcus pneumoniae (pneumococcus) is the main cause of bacterial pneumonia worldwide and has been studied extensively in this context. However, its role in chronic endobronchial infections and accompanying lower airway neutrophilic infiltration has received little attention. Severe and recurrent pneumonia are risk factors for chronic suppurative lung disease (CSLD) and bronchiectasis; the latter causes considerable morbidity and, in some populations, premature death in children and adults. Protracted bacterial bronchitis (PBB) is another chronic endobronchial infection associated with substantial morbidity...

Chronic cough in children is increasingly defined as a cough that lasts more than four weeks. It is recognized as a different entity than cough in adults. As a result, the diagnostic approach and management of chronic cough in children are no longer extrapolated from adult guidelines. These differences are attributed to the various characteristics of the respiratory tract, immunological system and nervous system in children. Specific paediatric guidelines and algorithms for chronic cough are now widely applied...

The most common clinical suppurative lung conditions in children are empyema, lung abscess, and bronchiectasis, and to a less often necrotizing pneumonia. Until recently, bronchiectasis was the most common form of persistent suppurative lung disease in children. Protracted bacterial bronchitis is a newly described chronic suppurative condition in children, which is less persistent but more common than bronchiectasis (1). In addition, the term "chronic suppurative lung disease" has been used recently to describe the clinical features of bronchiectasis when the radiographic features needed to make a diagnosis of bronchiectasis are absent...

BACKGROUND: Wet or productive cough is common in children with chronic cough. We formulated recommendations based on systematic reviews related to the management of chronic wet cough in children (aged ≤ 14 years) based on two key questions: (1) how effective are antibiotics in improving the resolution of cough? If so, what antibiotic should be used and for how long? and (2) when should children be referred for further investigations? METHODS: We used the CHEST expert cough panel's protocol for systematic reviews and the American College of Chest Physicians (CHEST) methodologic guidelines and GRADE framework (the Grading of Recommendations Assessment, Development and Evaluation)...

BACKGROUND: Chronic endobronchial infections in children are responsible for a high disease burden. Streptococcus pneumoniae is frequently isolated; however, few publications have described serotypes associated with non-invasive lower airway infection. METHODS: Paired nasopharyngeal (NP) swabs and bronchoalveolar lavage (BAL) fluids were collected from children undergoing bronchoscopy for chronic cough. NP swabs were also collected from asymptomatic children in otitis media surveillance studies (controls)...

Non-cystic fibrosis bronchiectasis again becomes a major health problem due to inappropriate antibiotic use and increasing frequency of protracted bacterial bronchitis. The aim was to determine the changes in etiology of bronchiectasis. Patients who admitted to Behçet Uz Children Hospital between 2005 and 2015 (n=110) were retrospectively examined. The etiology of bronchiectasis was detected as; primary ciliary dyskinesia 26.4%, protracted bacterial bronchitis 22.8%, primary immune deficiency 11.8%, bronchiolitis obliterans 8...

BACKGROUND: Protracted bacterial bronchitis (PBB) and bronchiectasis are distinct diagnostic entities that share common clinical and laboratory features. It is postulated, but remains unproved, that PBB precedes a diagnosis of bronchiectasis in a subgroup of children. In a cohort of children with PBB, our objectives were to (1) determine the medium-term risk of bronchiectasis and (2) identify risk factors for bronchiectasis and recurrent episodes of PBB. METHODS: One hundred sixty-one children with PBB and 25 control subjects were prospectively recruited to this cohort study...

BACKGROUND: Children with recurrent protracted bacterial bronchitis (PBB) and bronchiectasis share common features, and PBB is likely a forerunner to bronchiectasis. Both diseases are associated with neutrophilic inflammation and frequent isolation of potentially pathogenic microorganisms, including nontypeable Haemophilus influenzae (NTHi), from the lower airway. Defective alveolar macrophage phagocytosis of apoptotic bronchial epithelial cells (efferocytosis), as found in other chronic lung diseases, may also contribute to tissue damage and neutrophil persistence...

Cough is the single most common reason for primary care physician visits and, when chronic, a frequent indication for specialist referrals. In children, a chronic cough (>4 weeks) is associated with increased morbidity and reduced quality of life. One common cause of childhood chronic cough is protracted bacterial bronchitis (PBB), especially in children aged <6 years. PBB is characterized by a chronic wet or productive cough without signs of an alternative cause and responds to 2 weeks of appropriate antibiotics, such as amoxicillin-clavulanate...

Despite the high prevalence of cough in children, the topic has been poorly researched. Although pediatricians recognize that chronic cough in children is different from that in adults, this difference seems less recognizable to other health professionals. During childhood, the respiratory tract and nervous system undergo a series of anatomical and physiological maturation processes that influence the cough reflex. Additionally, immunological responses undergo developmental and memorial processes that make infection and congenital abnormalities the overwhelming cause of cough in children...

Protracted bacterial bronchitis (PBB) is the common cause of chronic cough in children worldwide, but its etiology has not been fully recognized in China. We retrospectively investigated a total of 66 hospitalized infants under the age of three years with chronic wet cough enrolled in the Affiliated Children's Hospital of Soochow University from October 2010 to March 2014. All patients underwent bronchoscopy and broncho-alveolar lavage (BAL) samples were processed for microbiological and cytological analysis...

Pro: Children with chronic cough present a diagnostic challenge. Protracted bacterial bronchitis (PBB) is a chronic, persistent bacterial infection of conducting airways defined by the presence of cough for longer than 4 weeks that resolves with antimicrobial therapy and without an alternative diagnosis. The diagnosis is made by the findings of increased bronchial secretions and edema of the lower airways on flexible bronchoscopy and positive cultures on bronchoalveolar lavage. It is speculated that an initial respiratory insult such as viral infection disrupts normal surface morphology and ciliary function, which leads to chronic self-perpetuating inflammation with the formation of bacterial biofilms, leading to PBB...

BACKGROUND: Clinical symptoms in children with pulmonary diseases are frequently non-specific. Rare diseases such as primary ciliary dyskinesia (PCD), cystic fibrosis (CF) or protracted bacterial bronchitis (PBB) can be easily missed at the general practitioner (GP). OBJECTIVE: To develop and test a questionnaire-based and data mining-supported tool providing diagnostic support for selected pulmonary diseases. METHODS: First, interviews with parents of affected children were conducted and analysed...

BACKGROUND: Wheezing is a common presentation in young children. Diagnosis and treatment of these children can be challenging, as arriving at a final diagnosis often requires a process of elimination. OBJECTIVE: This article aims to provide an algorithm for managing a young child with wheeze in the primary care setting. We will aim to address key questions of some controversy that relate to this algorithm: 1. Does the child actually have wheeze – how accurate is the parents' description? 2...

A chronic 'productive' or 'wet' cough is a common presenting complaint for patients attending the adult respiratory clinic. Most reviews and guidelines suggest that the causes of a productive cough are the same as those of a non-productive cough and as such the same diagnostic pathway should be followed. We suggest a different diagnostic approach for patients with a productive cough, focussing on the conditions that are the most likely causes of this problem. This review is intended to briefly summarise the epidemiology, clinical features, pathophysiology and treatment of a number of conditions which are often associated with chronic productive cough to aid decision making when encountering a patient with this often distressing symptom...

Chronic moist cough in children can be associated with serious pathologies. Protracted bacterial bronchitis remains a clinical diagnosis causing persistent moist cough, disturbed sleep, exercise intolerance and significant levels of morbidity. Management involves minimal investigations and prolonged courses of antibiotics.
