The use of plasmapheresis in a severe case of amiodarone-induced thyrotoxicosis


Advocate Lutheran General Hospital


Amiodarone-induced thyrotoxicosis (AIT) can be difficult to treat since amiodarone's long half-life leads to a persistent effect on thyroid function. We present a case of a 74-year-old male with severe AIT who presented with altered mentation and ultimately required intubation and intensive care for management of thyroid storm. Standard medical therapy for treatment of thyroid storm was initiated immediately, but the patient remained unresponsive with worsening biochemical parameters with increasing total T3 levels and sustained elevated levels of free T4 after 5 days of medical management. Due to the lack of a clinical and biochemical response to conventional medical therapy, the patient was started on plasmapheresis and underwent a total of 7 cycles of plasmapheresis over a period of 10 days. He significantly improved with plasmapheresis and was successfully bridged to a total thyroidectomy, which was completed without complications.
