What does ARD stand for?

• A. Antibiotic-responsive diarrhea
• B. Microbiota-responsive diarrhea
• C. Food-responsive enteropathy
• D. Steroid-responsive enteropathy

Answer: (A)

ARD stands for antibiotic-responsive diarrhea. The main idea being tested is what the acronym ARD means in chronic enteropathy: it refers to diarrhea that improves with antibiotic therapy, pointing to a microbial or dysbiosis-related component rather than a purely dietary or immunologic cause. Because antibiotics are the clue in ARD, this expansion is the best fit. In this framework, other terms describe different response patterns—food-responsive enteropathy means the diarrhea responds to dietary changes, steroid-responsive enteropathy to immunosuppressive treatment, and a term like microbiota-responsive diarrhea isn’t a standard designation. Understanding ARD helps guide management, highlighting when an antibiotic trial is a reasonable step to assess likelihood of bacterial-driven disease.
