Tracheal obstruction associated with a fungus ball. A case of primary tracheal candidiasis
Abstract:
An elderly patient developed acute respiratory failure secondary to airway obstruction by a Candida fungus ball which probably developed secondary to the use of broad-spectrum antibiotics when the patient had a decreased gag reflex while in a semicomatose state. The frequency of pulmonary fungus balls and their precipitating causes are briefly discussed. This potentially frequent, previously unreported complication should be recognized as a contributing factor in the development of acute respiratory failure requiring management by bronchoscopic techniques, as opposed to intubation.
Insights
A Candida fungus ball caused acute respiratory failure in an elderly patient, likely due to antibiotics and a reduced gag reflex. This complication may require bronchoscopic intervention instead of intubation.
Area of Science:
- Pulmonology
- Infectious Diseases
- Critical Care Medicine
Background:
- Broad-spectrum antibiotic use can disrupt normal flora, increasing the risk of opportunistic fungal infections.
- A decreased gag reflex, often seen in semicomatose patients, impairs airway protection and can lead to aspiration.
- Candida species are common causes of opportunistic infections, particularly in immunocompromised or debilitated individuals.
Observation:
- An elderly, semicomatose patient with a decreased gag reflex developed acute respiratory failure.
- Airway obstruction was identified as the cause, specifically a fungus ball composed of Candida.
- The fungus ball formation was suspected to be secondary to prior broad-spectrum antibiotic therapy.
Findings:
- Pulmonary fungus balls, while not frequently reported, can cause significant airway obstruction.
- This case highlights a previously underrecognized complication of antibiotic use and altered consciousness.
- The patient's acute respiratory failure was successfully managed with bronchoscopic techniques, avoiding endotracheal intubation.
Implications:
- Clinicians should consider pulmonary fungus balls as a potential cause of acute respiratory failure in at-risk patients.
- Recognition of this complication is crucial for appropriate and timely management.
- Bronchoscopic removal of fungus balls offers an alternative to intubation, potentially reducing associated risks.
