Neumonía eosinofílica crónica secundaria a levetiracetam

Abstract

Eosinophilic pulmonary diseases constitute a very heterogeneous group of diseases that share clinical manifestations, radiological and/or laboratory findings. Therefore, it is necessary to know the diagnostic criteria for each disease. Chronic idiopathic eosinophilic pneumonia is the most common eosinophilic pneumonia in non-tropical areas where parasitic infections is low. If a clear cause is identified, the most frequent is secondary to drugs and/or toxins. We present the case of a 21-year-old man diagnosed with chronic eosinophilic pneumonia secondary to treatment with levetiracetam, a generally safe and widely accepted drug in routine clinical practice. A search for the etiology of eosinophilic pulmonary diseases is essential, because identifying a possible cause would allow the withdrawal of the causative agent and to start corticosteroid therapy, so we could prevent the associated morbidity and mortality.
