Insights

DNase treatment rapidly improved clinical symptoms within 2 hours and radiologic findings within 24 hours in pediatric patients with atelectasis. This suggests DNase may be an effective treatment for infectious atelectasis in children without cystic fibrosis.

Area of Science:

  • Pulmonology
  • Pediatric Medicine
  • Pharmacology

Background:

  • Atelectasis lacks evidence-based treatments.
  • Persistent atelectasis in children often requires novel therapeutic approaches.
  • Current treatments like bronchodilators and physiotherapy are not always effective.

Purpose of the Study:

  • To evaluate the clinical and radiologic effects of DNase in pediatric patients with persistent atelectasis.
  • To assess DNase efficacy in non-cystic fibrosis children unresponsive to standard therapies.
  • To identify potential complications associated with DNase treatment for atelectasis.

Main Methods:

  • Retrospective descriptive study of non-cystic fibrosis pediatric patients treated with DNase (nebulized or endotracheal).
  • Inclusion criteria: persistent atelectasis unresponsive to bronchodilators and physiotherapy.
  • Endpoints: blood pCO2, heart rate, respiratory rate, FiO2, and chest X-ray scores before and after treatment.

Main Results:

  • Significant clinical improvement in most parameters within 2 hours (p < 0.01).
  • Significant improvement in chest X-ray scores within 24 hours (p < 0.001).
  • Temporary airway obstruction and desaturations occurred in 3 patients, possibly due to mucus mobilization.

Conclusions:

  • DNase demonstrated rapid clinical and radiologic improvement in pediatric patients with infectious atelectasis.
  • DNase may be a viable treatment option for atelectasis in non-cystic fibrosis pediatric patients.
  • Potential for mucus mobilization complications necessitates careful monitoring.

Atelectasis II: Pathophysiology

Atelectasis develops when alveoli lose their air and collapse inward. Because lung tissue is naturally elastic, these air sacs shrink rather than remaining open. Collapsed alveoli are no longer ventilated, reducing their role in gas exchange. Blood flow may continue in these regions, creating a ventilation–perfusion mismatch. Clinical findings include decreased breath sounds, dullness to percussion, reduced chest expansion, and decreased tactile fremitus as sound transmission through collapsed...
Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...
Cystic Fibrosis: Management01:24

Cystic Fibrosis: Management

Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Breathing01:05

Breathing

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...
Chronic Obstructive Pulmonary Disease II: Emphysema01:23

Chronic Obstructive Pulmonary Disease II: Emphysema

Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.
