A 70 year old man has diabetes, cardiopathy and Parkinson´s disease and has been treated with enalapril, metformin, aspirin, amiodarone, and levodopa. Due to symptoms of malaise, cognitive impairment, and depression, he seeks the advice of a family physician. Blood tests revealed his TSH levels were over 40 mU/mL. At this point, medical management of this patient should include the withdrawal of a medication the patient has been taking, a blood test for an antibody and the prescription of a new drug. The drug that should be withdrawn, the antibody that he should be tested for and the new drug that should be prescribed are, respectively:
A amiodarone, antithyroid peroxidase (anti-TPO) and levothyroxine.
B levodopa, antithyrotrophin receptor (TRAb) and liothyronine.
C amiodarone, antithyrotrophin receptor (TRAb) and levothyroxine.
D levodopa, antithyroid peroxidase (anti-TPO) and levothyroxine.
E amiodarone, antithyroid peroxidase (anti-TPO) and liothyronine.
