ObjectiveThe association between daptomycin exposure and eosinophilic pneumonia (EP) is mainly based on case reports. The purpose of this study was to evaluate the clinical characteristics and provide more evidence for better identify and management of daptomycin-induced eosinophilic pneumonia in clinical practice.MethodsLiterature from 1991 to October 31, 2021 on EP induced by daptomycin were collected for retrospective analysis.ResultsA total of 47 patients (40 male and 7 female) from 35 studies were included. The median age was 67 years (range 28-89), and 78.7% of patients were ≥60 years. Daptomycin was mainly used in patients undergoing osteoarticular infections (63.8%). Typical initial symptoms were fever (91.5%), cough (55.3%) and dyspnea (59.6%). The median onset time of symptom was 3 weeks. EP recurred in 14.9% of patients after the re-administration of daptomycin, and 57.1% of EP recurred within 24h. Most cases were accompanied by marked accumulation of eosinophils in peripheral (41 cases) and/or bronchoalveolar lavage fluid (27 cases). The main radiological features were pulmonary infiltration, ground glass opacity or consolidation in CT/CXR. All patients had symptom resolution after discontinuation of daptomycin except for one patient died due to the progression of the primary disease, the median time to symptoms relief was 3 days. Corticosteroids have been shown to help symptoms relief in some cases (59.6%).ConclusionDaptomycin-induced eosinophilic pneumonia is a rare and serious complication. Physicians should consider eosinophilic pneumonia as a differential diagnosis when receiving daptomycin therapy, particularly in elderly male patients.Copyright © 2022 Elsevier España, S.L.U.
