Migratory pulmonary infiltrates in a patient treated with sotalol

Beta-blockers may induce several types of adverse respiratory reaction such as asthma, interstitial lung disease with or without pleural effusion, systemic lupus erythematosus or hypersensitivity pneumonitis. More recently, bronchiolitis obliterans with organizing pneumonia (BOOP) has been described. We report here on pulmonary migratory infiltrates with combined histopathological features of both BOOP and eosinophilic pneumonia in a woman treated with sotalol long-term. The patient improved only partially with steroids. Tapering off corticosteroid dosage resulted in relapse, and complete recovery was only obtained after sotalol was stopped.
