Re: American Gastroenterological Association Institute Guideline on therapeutic drug monitoring in inflammatory bowel disease
The recently published American Gastroenterological Association (AGA) guideline on therapeutic drug monitoring (TDM) in inflammatory bowel disease (IBD) provides important and useful perspectives for individuals caring for and managing individuals with IBD and also for researchers focusing on this area (1). The guideline reviews key aspects of the roles that TDM increasingly has in the management of individuals with IBD and highlights key concepts. It also illustrates that many of these areas are supported by scanty evidence. Consequently, this also serves to prompt further study that might expand the evidence base accordingly.
