Acute Eosinophilic Pneumonia in a Patient with Inflammatory Bowel Disease
Published on: 2014-02-01
Acute eosinophilic pneumonia (AEP) is an uncommon respiratory disease characterized by increased eosinophilis in bronchoalveolar lavage fluid. It may be triggered by a drug, infection, or dust. The etiology may also be idiopathic, in which case the patient is usually a young, previously healthy smoker. We report a case of AEP in an elderly non-smoking patient with ulcerative colitis, treated with a total colectomy one decade prior to presentation. Though cases of AEP have been reported in association with anti-metabolite therapy for inflammatory bowel disease, our patient was not taking any such medications. He also did not have exposure to any other known triggers of AEP, and did not fit the usual clinical picture of idiopathic AEP. Therefore, we suspect that this case of AEP was a complication of the patient’s inflammatory bowel disease itself.
