Editorial: Functional Dyspepsia Treatment: Trials and Tribulations of Targeted Strategies.

While functional dyspepsia (FD) is an exceedingly common disorder, the number of treatment options remains limited, and strategies for the individualized implementation of these therapies largely are lacking. In the current issue of American Journal of Gastroenterology, Saito and colleagues report on a secondary analysis of data from the Functional Dyspepsia Treatment Trial, specifically examining the role of two candidate genetic markers in predicting FD response to antidepressant treatments. Though the current study yielded a negative result, it nevertheless emphasizes the importance of our continued pursuit of therapeutic biomarkers in order to move beyond "one-size-fits-all" approaches to the treatment of FD and related disorders.
