Filter by:Children with lung and airway malformations or early structural lung damage face significant challenges, often leading to recurrent respiratory infections, hospitalizations, and decreased quality of life. Despite various interventions, effective strategies are urgently needed. The link between these conditions and persistent bacterial bronchitis remains unclear, possibly due to compromised airways and reduced mucociliary clearance. Although antibiotics can alleviate symptoms, relapse is common. Experts often prescribe prophylactic azithromycin, despite limited evidence of its benefits. Azithromycin shows promise due to its anti-inflammatory and immunomodulatory effects but lacks thorough evaluation in this population. To address this gap, we propose a double-blind, randomized controlled trial to assess azithromycin's effectiveness and safety in preventing respiratory infections in children with these conditions. This research aims to inform clinical practice and improve the health of affected children and their families.
Introduction: Children born with a blind-ending gullet (oesophagus), or Oesophageal Atresia (OA), need to undergo surgical correction in the first week of life. OA is often accompanied by a weakened windpipe (trachea), known as tracheomalacia (TM). TM entails that the windpipe collapses during expiration. Severe TM can cause respiratory symptoms, including frequent respiratory tract infections and blue spells, that can potentially lead to life-threatening events. In some patients, major secondary surgical treatment may be indicated. This surgical procedure involves widening the trachea (using sutures) to prevent collapse, known as secondary posterior tracheopexy (SPT). Prior to performing this SPT, complications and negative consequences of TM may have already occurred. This may be prevented by performing this procedure during the primary OA correction, called a primary posterior tracheopexy (PPT). The aim of this trial is to determine if a PPT can decrease - or prevent - tracheal collapse in newborns with OA and TM, compared to a wait-and-see policy (no-PPT). Methods: This is an international multicentre double-blind randomised controlled trial. Seventy eight children with OA type C will be included. Patients will be included after written parental informed consent. Half of the patients will be randomly allocated to the PPT-group and half to the no-PPT-group. The degree and location of TM are evaluated through preoperative, intraoperative and two postoperative videoscopic examinations of the trachea (tracheobronchoscopy). Whether TM symptoms occur is assessed during three routine follow-up consultations until the age of 6 months. The primary outcome is the degree of collapse of the tracheal wall during the intraoperative tracheobronchoscopy (after performing the PPT/no-PPT), measured in percentages. Risks and burden: Since OA correction with PPT (more recently implemented in centres of expertise) and without PPT (wait-and-see policy) are both accepted and safe treatment options, participating in the trial does not pose an increased risk or burden with regards to the treatment. Performing tracheobronchoscopies may pose a potential burden. However, a tracheobronchoscopy is a routine diagnostic procedure commonly used to safely assess the trachea. Complications of a tracheobronchoscopy are rare. Also, many of the tracheobronchoscopies are routinely performed as part of standard care for these patients, regardless of the trial.
The purpose of this pilot interventional study is to evaluate the use of Dynamic Airway Computed Tomography (DA-CT) for diagnosis of tracheomalacia in children 0-18 years for whom flexible bronchoscopy has been performed. The primary aims are to evaluate the diagnostic accuracy, image quality, and radiation exposure of DA-CT as a potential noninvasive alternative to the gold standard of flexible bronchoscopy in the diagnosis of tracheomalacia. The results from this pilot study will help to estimate sample size for a larger-scale study with more precise estimates of DA-CT diagnostic potential.
This is a phase I study to evaluate the safety, efficacy and tolerability of a novel tracheal replacement therapy using cadaveric de-cellularised tracheal scaffold and patients' own mesenchymal cells isolated from a sample of their bone marrow in patients' who suffer from severe tracheal malacia or stenosis.
The purpose of this study is to evaluate respiratory symptoms and their impact in the quality of life and after treatment of the respiratory condition (tracheobronchomalacia - TBM).
The main purpose of this study is use a new type of measurement to help decide what kind of therapy would help people with a collapsing windpipe or tracheomalacia.
