Non-Cystic-Fibrosis Bronchiectasis in Children: A Persisting Problem in Developing Countries

Background: Non-cystic-fibrosis (non-CF) bronchiectasis in childhood is still one of the most common causes of childhood morbidity in developing countries. The management of these patients remains problematic, and there are few studies of long-term outcome. Objective: The aim of this retrospective study was to define the general characteristics, underlying causative factors and long-term follow-up results of non-CF bronchiectasis patients. Methods: One hundred and eleven consecutive children, diagnosed with non-CF bronchiectasis were included in the study. General characteristics and underlying causes were recorded from the medical records. Clinical outcomes were evaluated in terms of lung function tests, annual exacerbation rates and patient/parent perception of health status. Results: Mean age of the patients was 7.4 ± 3.7 years at presentation, and patients had been followed 4.7 ± 2.7 years on average. In 62.2% of the patients, an underlying etiology was identified, whereas postinfectious bronchiectasis was the most common (29.7%). In spite of intensive medical treatment, 23.4% of the patients required surgery. The annual lower respiratory infection rate has decreased from a mean of 6.6 ± 4.0 to 2.9 ± 2.9 during follow-up (p < 0.0001). Lung function tests were also found to be improved (mean FEV1% 63.3 ± 21.0 vs. 73.9 ± 27.9; p = 0.01; mean FVC% 68.1 ± 22.2 vs. 74.0 ± 24.8; p = 0.04). There was clinical improvement in both the surgical (73%) and medical (70.1%) groups (p > 0.05). Conclusion: In conclusion, bronchiectasis remains a disease of concern to pediatricians, particularly in developing countries. Infections are still important causes of bronchiectasis, and clinical improvement can be achieved by appropriate treatment. Although medical treatment is the mainstay of management, surgery should be considered in selected patients.

Obstructive sleep disordered breathing in 2- to 18-year-old children: Diagnosis and management

This document summarises the conclusions of a European Respiratory Society Task Force on the diagnosis and management of obstructive sleep disordered breathing (SDB) in childhood and refers to children aged 2–18 years. Prospective cohort studies describing the natural history of SDB or randomised, double-blind, placebo-controlled trials regarding its management are scarce. Selected evidence (362 articles) can be consolidated into seven management steps. SDB is suspected when symptoms or abnormalities related to upper airway obstruction are present (step 1). Central nervous or cardiovascular system morbidity, growth failure or enuresis and predictors of SDB persistence in the long-term are recognised (steps 2 and 3), and SDB severity is determined objectively preferably using polysomnography (step 4). Children with an apnoea–hypopnoea index (AHI) >5 episodes·h−1, those with an AHI of 1–5 episodes·h−1 and the presence of morbidity or factors predicting SDB persistence, and children with complex conditions (e.g. Down syndrome and Prader–Willi syndrome) all appear to benefit from treatment (step 5). Treatment interventions are usually implemented in a stepwise fashion addressing all abnormalities that predispose to SDB (step 6) with re-evaluation after each intervention to detect residual disease and to determine the need for additional treatment (step 7). Management of obstructive sleep disordered breathing in childhood should follow a stepwise approach http://ow.ly/SdKwD

Flexible bronchoscopy for diagnosis and follow up of childhood endobronchial tuberculosis.

Background: In this study, our aim was to determine the clinical and bronchoscopic outcome of the endobronchial tuberculosis (ETB). Methods: Patients with suspected tuberculosis (TB) or TB patients with an inadequate response to 8 weeks of antituberculosis treatment were enrolled in the study. Results: Seventy patients were included to the study and 118 flexible bronchoscopies were performed. ETB was present in 33 (47%) patients. There was isolated compression in 14 cases, caseous lesions in 13, granuloma formation in 6, polypoid lesions in 2, adenopathy protrusion in 1, and mucosal erosion in 1 case. The mean duration of bronchoscopic resolution of endobronchial lesions was 5.50 ± 2.74 months. Mycobacterium tuberculosis was isolated from gastric lavage in 10% and from bronchoalveolar lavage in 12.8% of 70 cases. When both of the procedures were performed concurrently, the isolation rate increased to 20%. Transient hypoxia resolving with nasal O2 was observed in 3 patients as a complication of bronchoscopy. Conclusions: Bronchoscopy offered a safe and rapid means of confirming the diagnosis of ETB.

Home Ventilation for Children with Chronic Respiratory Failure in Istanbul

Background: The number of children on home mechanical ventilation (HMV) has increased markedly in Europe and North America but little is known about the HMV use and outcomes in children in Turkey. Objective: To review clinical conditions and outcome of children who were discharged from the hospital on respiratory support. Methods: Thirty-four patients assessed at the Marmara University Hospital in Istanbul who had been receiving ventilatory support at home for more than 3 months were included in the study. Results: Thirty-four patients with a median age of 5.1 years were discharged home with ventilatory support. HMV was started in 2001 at our institution and the number of children treated has increased substantially since then (2001: n = 1, 2002: n = 3, 2003: n = 3, 2004: n = 2, 2005: n = 14, 2006: n = 11).Ventilatory support was started at a median age of 1.8 years and continued for 13 months. Eleven (32.4%) patients received invasive mechanical ventilation via tracheostomy and 23 (67.6%) patients received noninvasive mechanical ventilation. Sixteen children (47.1%) were on noninvasive mechanical ventilation via nasal mask while 7 (20.6%) used a face mask. Seven (20.6%) patients received ventilatory support for 24 h and 27 (79.4%) patients were supported only during sleep. Twenty-four (70.6%) children received supplemental oxygen in addition to ventilatory support. Three patients successfully came off ventilatory support; 11 patients died during follow-up. None of the patients had home nursing and there were no life-threatening complications. Conclusions: A rapidly rising trend of HMV use in chronic respiratory failure (CRF) has been observed in this study. HMV can be safely applied in selected children with CRF with close monitoring and proper follow-up in developing countries despite the lack of home nursing.

Withdrawal of inhaled steroids in children with non‐cystic fibrosis bronchiectasis

Background:  To study the effects of inhaled steroid withdrawal on bronchial hyperreactivity, sputum inflammatory markers and neutrophilic apoptosis in children with non‐cystic fibrosis (non‐CF) bronchiectasis.

Effect of night symptoms and disease severity on subjective sleep quality in children with non-cystic-fibrosis bronchiectasis.

Night‐time symptoms and hypoxemia during sleep may affect sleep quality in children with chronic lung disease such as bronchiectasis. Poor sleep quality may impair growth, learning, and emotional development of children. Our aim was to assess the sleep quality and associated factors in children with non‐cystic fibrosis bronchiectasis.

Flexible bronchoscopy as a valuable tool in the evaluation of persistent wheezing in children

BACKGROUND Persistent wheezing is a common problem in early childhood and leads to a diagnostic dilemma, excessive investigations, drug administration and additional cost. OBJECTIVE To determine the efficacy and the safety of FOB in children with persistent wheezing despite bronchodilator and inhaled steroid therapy. METHODS Patients with persistent wheezing that lasted at least 6 weeks and did not respond to bronchodilator and inhaled steroid therapy and to whom flexible bronchoscopy was performed were included to the study. RESULTS Between 1997 and 2009; 113 patients were enrolled to the study. Sixty-three percent of the children were male. Median age was 14 months at presentation and median duration of symptoms was 5 months. Bronchoscopy revealed pathological findings in 48% of the patients. Thirty-eight patients had malacia disorders, 14 had foreign body aspiration and two had external compression of airways which were later diagnosed as vascular ring. Major and minor complications were not seen in 92% of the patients while transient hypoxia was seen in 6%, stridor in 1% and tachycardia in 1% of the patients. CONCLUSION Flexible bronchoscopy provided rapid and definitive diagnosis for our patients with persistent wheezing without any major complications. This study is one of the largest studies concerning persistent wheezing. Early bronchoscopic evaluation can reduce cost by providing rapid and accurate diagnosis and preventing unnecessary investigations and drug administration. Flexible bronchoscopy is a safe procedure and should be considered in the evaluation of children with persistent wheezing.

How do we recognize the child with OSAS

Obstructive sleep‐disordered breathing includes a spectrum of clinical entities with variable severity ranging from primary snoring to obstructive sleep apnea syndrome (OSAS). The clinical suspicion for OSAS is most often raised by parental report of specific symptoms and/or abnormalities identified by the physical examination which predispose to upper airway obstruction (e.g., adenotonsillar hypertrophy, obesity, craniofacial abnormalities, neuromuscular disorders). Symptoms and signs of OSAS are classified into those directly related to the intermittent pharyngeal airway obstruction (e.g., parental report of snoring, apneic events) and into morbidity resulting from the upper airway obstruction (e.g., increased daytime sleepiness, hyperactivity, poor school performance, inadequate somatic growth rate or enuresis). History of premature birth and a family history of OSAS as well as obesity and African American ethnicity are associated with increased risk of sleep‐disordered breathing in childhood. Polysomnography is the gold standard method for the diagnosis of OSAS but may not be always feasible, especially in low‐income countries or non‐tertiary hospitals. Nocturnal oximetry and/or sleep questionnaires may be used to identify the child at high risk of OSAS when polysomnography is not an option. Endoscopy and MRI of the upper airway may help to identify the level(s) of upper airway obstruction and to evaluate the dynamic mechanics of the upper airway, especially in children with combined abnormalities.
