Acute Eosinophilic Pneumonia Secondary to Daptomycin

Area of Science:

• Infectious Diseases
• Pulmonology
• Pharmacology

Background:

• Daptomycin is a crucial antibiotic for treating Gram-positive bacterial infections, often reserved for severe cases.
• Acute eosinophilic pneumonia (AEP) is a recognized, albeit rare, adverse drug reaction associated with certain medications.

Observation:

• A 79-year-old male patient developed AEP following the initiation of daptomycin therapy for a knee arthroplasty infection.
• The patient presented with symptoms consistent with AEP shortly after starting the antibiotic.

Findings:

• Discontinuation of daptomycin and appropriate medical management resulted in significant improvement of the patient's AEP symptoms.
• This case confirms AEP as an uncommon but potential side effect of daptomycin treatment.

Implications:

• Early identification of AEP in patients receiving daptomycin is critical for timely intervention.
• Awareness of this adverse event is important for clinicians managing severe infections with daptomycin.
• This case underscores the need for vigilance regarding potential drug-induced pulmonary complications.
