title: [Case of minocycline-induced acute eosinophilic pneumonia accompanied by marked neutrophilia in the peripheral blood].
abstract: A 37-year-old woman presenting with high fever, dry cough and progressive dyspnea was admitted to our hospital. She took 100 mg of minocycline hydrochloride orally because of a common cold one day prior to her admission. A chest CT scan showed diffuse ground-glass opacities with interlobular septal thickening and thickening of bronchovascular bundles. An analysis of bronchoalveolar lavage fluid showed an increase in both the total cell counts and the number of eosinophils. The result of a lymphocyte stimulation test performed on peripheral blood lymphocytes was positive for minocycline. This patient had a history of pneumonia with similar clinical and radiographic findings, which had developed while receiving minocycline. As a result, we made a diagnosis of minocycline-induced acute eosinophilic pneumonia. Her symptoms and radiographic findings improved within a few days after admission. Corticosteroid therapy was effective. A marked increase of peripheral blood neutrophils were noted on admission. The serum levels of IL-8 and G-CSF increased at the early phase of the disease, but thereafter decreased in association with neutrophils, thus suggesting the contribution of these cytokines to the early phase neutrophilia in this case.
