Etiological factors in child bronchial asthma

Area of Science:

• Pediatrics
• Immunology
• Allergology

Background:

• Asthma etiology understanding has evolved from solely extrinsic factors.
• Previous statistics on asthma triggers are outdated and limited.
• Childhood bronchial asthma requires updated etiological analysis.

Purpose of the Study:

• To investigate the prevalence of different activating mechanisms in childhood bronchial asthma.
• To analyze the influence of bacterial factors versus extrinsic factors in pediatric asthma.
• To evaluate the role of age, family history, and allergic comorbidities in asthma development.

Main Methods:

• Retrospective analysis of 700 pediatric bronchial asthma case histories.
• Data collection included sex, age of onset, family history, and allergic disorders.
• Intracutaneous testing and disease evolution over a minimum three-year treatment period were assessed.

Main Results:

• A purely bacterial cause was identified in 54% of cases.
• Purely extrinsic factors accounted for 10% of cases.
• Bacterial asthma, including mixed cases, constituted 94.7% of the study population, predominantly in children under one year.

Conclusions:

• Bacterial factors play a crucial role in the development of childhood bronchial asthma.
• Early-onset asthma in infants is strongly associated with bacterial triggers.
• Re-evaluation of asthma management strategies considering bacterial etiology is recommended.
