Mr. Harper comes to your office after 10 years. The last time you saw him, you prescribed him triple therapy antibiotics for his H. pylori infection and counseled him on the his use of NSAIDS and its role in exacerbating his disease process. He now returns to you again on the urge of his doting wife. While she initially believed Mr. Harper was on a new routine because of his noticeable weight loss, she now fears he looks emaciated and does not understand why. On questioning him, you find out the Mr. Harper finished his course of antibiotics, but did not take it on the schedule you prescribed; eventually taking them on a prolonged self-directed course. He now has regular epigastric pain. You confirm with Mr. Harper that he has continued his lifestyle of alcohol abstinence.
