15. A 50-year-old man is seen in the emergency department
complaining of abdominal pain and diarrhea. After evaluation
and rehydration, the patient is discharged home with a diagnosis of viral gastroenteritis. During his workup, however, the intern taking care of the patient ordered a full array of liver function tests, which revealed an elevated gamma-glutamyl ranspeptidase (GGT). The patient was advised to follow up with his primary care physician. The patient now presents in the clinic for evaluation of this isolated laboratory abnormality.He reports
feeling healthy since recovering and never having a history
of liver trouble.When asked, he reports drinking only socially and denies any illicit drug use. Current medications
include acetaminophen for osteoarthritis, atorvastatin
for dyslipidemia, amiodarone for a persistent
supraventricular tachycardia, and metformin for recently
diagnosed diabetes. In addition to these conditions, he
suffers from depressive symptoms and was recently fired
from his job. Physical examination is unremarkable
except for mild rhinophyma. Which of the following is
most likely to explain this patient™s elevated GGT level?
(A) Acetaminophen
(B) Alcohol
© Amiodarone
(D) Atorvastatin
(E) Metformin
