Insights

Pediatric bronchiectasis exacerbations often present with cough changes. Oral antibiotics fail in 35% of cases, with prophylactic antibiotics increasing this risk.

Area of Science:

  • Pediatric Pulmonology
  • Respiratory Medicine
  • Clinical Research

Background:

  • Children with bronchiectasis experience frequent acute pulmonary exacerbations.
  • Many exacerbations necessitate hospitalization due to treatment failure with oral therapies.
  • Standardized definitions and data on exacerbation features are limited.

Purpose of the Study:

  • To identify clinical and investigational features of exacerbations in pediatric non-cystic fibrosis bronchiectasis.
  • To determine the proportion of exacerbations unresponsive to oral antibiotics.
  • To identify factors associated with oral therapy failure.

Main Methods:

  • Retrospective cohort study of 115 exacerbations in 30 children with non-cystic fibrosis bronchiectasis.
  • Data on clinical features, investigations, and treatments were extracted and analyzed.
  • Diagnosis of bronchiectasis was confirmed by High-Resolution Computed Tomography (HRCT) of the chest.

Main Results:

  • Increased cough frequency (88%) and altered cough character (67%) were most common symptoms.
  • Fever (28%), increased sputum volume (42%), and purulence (35%) were frequent.
  • 35% of exacerbations failed oral antibiotic therapy, requiring hospitalization.
  • Prophylactic antibiotic use was a significant predictor of oral therapy failure (aOR 6.77, p=0.003).

Conclusions:

  • Key clinical features of pediatric non-CF bronchiectasis exacerbations include cough changes and worsening chest signs.
  • A significant proportion of exacerbations do not resolve with oral antibiotics.
  • Prophylactic antibiotic use is associated with an increased risk of oral therapy failure in pediatric bronchiectasis exacerbations.

Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features

Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...

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-IV: Assessement and Diagnostic Studies

Assessing and diagnosing Chronic Obstructive Pulmonary Disease (COPD) involves a detailed approach that includes a comprehensive review of medical history, physical examination, and a variety of diagnostic tests. This thorough evaluation is essential to ensure an accurate diagnosis and guide effective management strategies.

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...

Chronic Obstructive Pulmonary Disease IV: Clinical Manifestations

Chronic Obstructive Pulmonary Disease, or COPD, is a long-term condition marked by persistent and only partially reversible airflow limitation. It involves two overlapping conditions—chronic bronchitis and emphysema—which often co-appear but differ in dominant symptoms and underlying mechanisms.Chronic Bronchitis FeaturesChronic bronchitis presents with a persistent productive cough and thick, sometimes purulent mucus due to airway inflammation, enlarged mucus glands, and goblet cell...

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.
