摘　　要：Daptomycin induced acute eosinophilic pneumonia is a rare and potentially life threatening condition characterized by rapid respiratory failure, pulmonary infiltrates and eosinophilia. Risk factors for acute eosinophilic pneumonia include smoking, environmental irritants or inhalants and certain medications such as Daptomycin [1]. In this review of literature, we aim to explore the potential triggers for developing acute eosinophilic pneumonia in patients exposed to Daptomycin. The exact immune mechanism for daptomycin induced AEP is unknown, however the current proposed mechanism describes a T helper 2 lymphocyte response to inactivated daptomycin in the pulmonary surfactant, which leads to eosinophilia. Disordered T regulatory cell function is seen in patients with certain cancers, allergies and autoimmune conditions. We propose that patients with these underlying risk factors may be at increased risk of developing AEP after becoming exposed to Daptomycin. Understanding potential risk factors is crucial for health care workers as it allows them to identify susceptible populations, explore preventative measures and treat accordingly.Daptomycin induced acute eosinophilic pneumonia is a rare and potentially life threatening condition characterized by rapid respiratory failure, pulmonary infiltrates and eosinophilia.
