Abstract
Aim of the study
Midgut volvulus is a potentially life-threatening condition which is based on intestinal ischemia and reperfusion (I/R) injury. Remote ischemia conditioning (RIC) applied to a limb can protect distant organs such as heart and kidney. The aims of this study were to investigate the effect of RIC on a model of midgut volvulus and to explore its underlying mechanism of action.
Methods
Six-weeks old C57BL/6 mice were studied: (a) sham (n = 4): laparotomy alone. (b) Intestinal I/R injury (n = 5): occlusion of the superior mesenteric artery (SMA) for 45 min followed by reperfusion. (c) Intestinal I/R (as in group above) with RIC immediately after reperfusion (n = 5). RIC consisted of 4 cycles of 5 min hind limb ischemia followed by 5 min reperfusion. 24-h after laparotomy, animals were euthanized, and the small intestine (same distance from cecum) was harvested. The intestine was examined for inflammatory cytokines (TNF-α and IL-6), epithelial proliferation marker Ki67 and stem cell marker Lgr5 expression.
Main results
Compared to sham, the small intestine of IR mice had more intestinal damage, increased expression of inflammatory cytokines, decreased intestinal proliferation and stem cell activity. RIC significantly counteracted all these changes.
Conclusions
Remote ischemia conditioning avoids intestinal damage due to I/R injury. This beneficial effect is associated with decreased intestinal inflammation and enhanced intestinal regeneration. This study implicates that RIC is a novel non-invasive intervention to reduce the intestinal damage occurring in midgut volvulus.
