[Amiodarone-induced pulmonary fibrosis]

Abstract

The most feared side-effect of long-term amiodarone therapy is progressive alveolitis/pneumonitis leading to pulmonary fibrosis. The case history of a patient is presented who received amiodarone unnecessarily in a high dose (600 mg/day) for 4 years: drug-induced dermatopathy, hypothyroidism and lung fibrosis developed. After cessation of amiodarone treatment the pulmonary complication did not disappear therefore glucocorticoid therapy was introduced. New-onset improductive cough, dyspnea, fever and/or enhanced erythrocyte sedimentation rate may suggest the presence of amiodarone pulmonary toxicity and may form the basis of indication of high-resolution computed tomography (HRCT). Amiodarone-induced pulmonary involvement can be shown by HRCT early, before the appearance of any considerable abnormality of chest radiography.
