Abstract

Purpose

Total parenteral nutrition causes liver damage in patients with short bowel syndrome (SBS), in whom intestinal failure-associated liver disease (IFALD) is the strongest risk factor for mortality. We previously demonstrated the efficacy of dipeptidyl peptidase-4 inhibitors (DPP4-Is) for nutritional absorption and intestinal barrier function enhancement. Herein, we investigated the efficacy of DPP4-Is in preventing liver damage in SBS rat models.

Methods

Rats were allocated to one of five groups: normal saline (NS) + sham, DPP4-I + sham, NS + SBS, DPP4-I + SBS, and GLP-2 + SBS. DPP4-I or NS was administered orally once daily. Serum aspartate aminotransferase, alanine aminotransferase (ALT), alkaline phosphatase, and total bile acid levels were measured to assess liver function. Moreover, we evaluated liver damage using the SAF (steatosis activity fibrosis) score, which is also used to assess nonalcoholic steatohepatitis.

Results

ALT levels and SAF scores were significantly lower in the DPP4-I + SBS group than in the NS + SBS group. Jejunal and ileal villus heights were significantly higher in the DPP4-I + SBS group than in the GLP-2 + SBS group.

Conclusions

The downregulation of ALT levels and SAF scores triggered by DPP4-I use may be correlated with DPP4-I-induced adiposis inhibition in SBS and NASH models. Therefore, DPP4-I may be used to reduce IFALD in patients with SBS.
