Review Question - QID 212470

A 58-year-old male comes to the clinic complaining of joint pain and diarrhea. He reports that for the past year he has been experiencing aches at various joints including the knees, wrists, and elbows. There is no temporal pattern, and nothing seems to make it better. About 3 months ago he noticed that his stool would float and was difficult to flush. “It seems to get worse when I eat bread but I can’t be sure,” he claims. He reports a 10-pound unintentional weight loss over the past 2 months, fatigue, and diarrhea. He denies ulcers, fever, night sweats, chest pain, or palpitations. A histological sample of his endoscope sample is shown in Figure A. What is the best treatment for this patient?
