Intestinal ion transport and diarrheal disease.
The physiology of intestinal electrolyte transport is currently an area of intense research interest. Also, reports regularly appear that define possible roles of various endocrine, paracrine, and neurohumoral substances in regulating intestinal ion and water flux. A vast body of knowledge has appeared recently that focuses on the action of specific intracellular mediators or second messengers and certain biochemical events that are thought to be involved in this transport process. This area of research has drawn the attention of the clinical investigator as well as the basic scientist because of the implications of these findings to the understanding of secretory disorders of the gastrointestinal tract, in particular diarrheal disease. The purpose of this review is to focus on recent findings reported in three major areas: the physiology of intestinal electrolyte transport and its regulation; the pathophysiology of secretory diarrhea; and current thoughts and practices in the therapeutic approach to the disease.
