Abstract :

Amiodarone is highly efficacious as a medical therapy for cardiac arrhythmias. Amiodarone pulmonary toxicity, which can be presented as eosinophilic pneumonia, organizing pneumonia, acute respiratory distress syndrome (ARDS), diffuse alveolar hemorrhage, or pulmonary nodules and masses, is one of many severe potential side effects of this medication. The mechanisms involved in amiodarone-induced lung injury remain unclear, but may include direct toxic effect or an indirect immunologic reaction. This case involves a patient who developed amiodarone toxicity requiring intubation secondary to ARDS after a short course on a low dose of the medication. In this study a 79-year-old female who was presented to the emergency department with a two-day history of productive cough, pleurisy, worsening fatigue, and shortness of breath was considered. She had been on amiodarone for the previous six weeks for treatment of atrial flutter/fibrillation. Chest computed tomography showed diffused patchy foci of ground glass opacification in both lungs, likely secondary to a drug reaction from amiodarone toxicity. Patient had increased oxygen requirements throughout her hospitalization despite treatment with high dose steroids, diuresis and empiric antibiotic coverage. She required non-invasive ventilation with increasing frequency, later requiring intubation, and eventual withdrawal from life-sustaining measures. Amiodarone toxicity is a diagnosis of exclusion and remains perplexing from both a management and prognostic perspective. There are documented effects on the thyroid, heart, liver, skin, bone marrow, eyes, and lungs. While toxicity is rare, the potential complications can be lethal. Therefore, this medication should be used with caution due to its potential unpredictable side effect profile.
