Eosinophilic pneumonia presenting as life-threatening ARDS

Area of Science:

• Pulmonology
• Critical Care Medicine
• Psychiatry

Background:

• A 25-year-old woman presented with acute respiratory failure and shock 24 hours after psychiatric hospitalization.
• Her medical history included a suicide attempt with lye ingestion and initiation of new medications (paroxetine, alprazolam, valproic acid) and smoking.

Observation:

• The patient required intensive care unit admission with mechanical ventilation and vasopressor support.
• Initial diagnosis considered healthcare-associated pneumonia, but chest radiography showed bilateral infiltrates.
• Peripheral blood eosinophilia and bronchoalveolar lavage findings (50% eosinophils) suggested an alternative diagnosis.

Findings:

• The patient was treated with corticosteroids for suspected eosinophilic pneumonia.
• Following steroid administration, she rapidly improved, discontinuing vasopressors within 24 hours.
• She was successfully extubated 4 days after starting steroid therapy.

Implications:

• This case highlights eosinophilic pneumonia as a potential cause of acute respiratory failure in patients with specific medication exposures and recent psychiatric hospitalization.
• Early recognition and prompt treatment with corticosteroids are crucial for favorable outcomes.
• The interplay between psychiatric treatment, medication, and respiratory complications warrants further investigation.
