Treating short bowel syndrome with pharmacotherapy.

INTRODUCTION: Short bowel syndrome (SBS) has traditionally been regarded as a rapidly fatal medical catastrophe. The advent of pharmacological options directly targeting disease pathophysiology justified this review. AREAS COVERED: Since the 1970s, home parenteral nutrition has reduced mortality, converting SBS into a chronic and disabling compensated and occasionally curable illness. Off-label antidiarrheal drugs and related products, though having minimal scientific evidence of efficacy, represent the standard-of-care and are here reviewed. Trophic intestinal hormones, including GLP-2 and its analogs, have great promise for alleviating malabsorption, the most important symptom within a nonsurgical, routine outpatient framework. Current indications involve adults with massive intestinal losses (fecal wet weight >1500 g/day). Surgical options such as intestinal lengthening or transplantation are also addressed although these options are considerably more aggressive and have stricter indications. EXPERT OPINION: GLP-2 analogs are the first candidates from a pioneering pharmacotherapic family within the SBS framework, namely disease-modifying, absorption-restoring agents. This family of drugs, potentially applicable in all contexts of severe intestinal loss, could become the therapeutic benchmark of the near future.
