Advances in Understanding Recurrent Pulmonary Infections Following Foreign Body Aspiration: A Narrative Review

Area of Science:

• Pulmonology
• Infectious Diseases
• Foreign Body Aspiration

Background:

• Recurrent pulmonary infections (RPIs) are complex and challenging to diagnose, often stemming from aspiration or foreign bodies.
• These infections can involve bacterial, viral, or fungal agents, leading to lung inflammation and damage.
• RPIs are associated with poor prognosis and significant mortality from pulmonary causes.

Purpose of the Study:

• To review the pathogenesis, diagnosis, management, and prevention of RPIs caused by foreign body aspiration.
• To highlight the increased risk in pediatric and elderly populations.
• To inform future research, prevention, and treatment strategies for RPIs.

Main Methods:

• This study is a narrative review of current knowledge.
• It synthesizes information on RPIs secondary to foreign body aspiration.
• Emphasis is placed on clinical presentations, diagnostic methods, and treatment approaches.

Main Results:

• Foreign body aspiration is a key risk factor for RPIs.
• Pediatric and elderly individuals are particularly vulnerable.
• Effective management includes appropriate antimicrobial therapy and foreign body removal.

Conclusions:

• Understanding RPIs from foreign body aspiration is vital for clinical management.
• Timely diagnosis and intervention, including foreign body removal, are critical.
• Improved strategies are needed to reduce RPI incidence and mortality.
