Acute necrotizing pneumonitis and hyperglycemia after amiodarone therapy. Case report and review of amiodarone-associated pulmonary disease.
Amiodarone is a new and powerful antiarrhythmic agent currently under investigation in North America. In the past two years, there have been increasing reports of serious side effects associated with its use, including 14 cases of pneumonitis or pulmonary fibrosis. This report describes a case of acute necrotizing pneumonitis, a complication that has not been observed previously with amiodarone therapy. Amiodarone also appeared to alter carbohydrate metabolism in this patient. Metabolic changes induced by this drug may be mediated by superoxide radicals. A high index of suspicion for pulmonary complications should be maintained in patients taking amiodarone, and nonspecific respiratory complaints should be investigated carefully.
