Serum substance P and vasoactive intestinal peptide levels in infants with acute intussusception.

Abstract

ObjectiveWe aimed to investigate the role of the intestinal neurotransmitters vasoactive intestinal peptide (VIP) and substance P (SP) at different time points in infants with acute intussusception.MethodsThirty patients who were diagnosed with acute intussusception were enrolled in the study and classified as the experimental group. Another 30 patients with an indirect inguinal hernia who had no intestinal injury were included as the control group. Serum SP and VIP levels at different time points, including pre- and postoperation, were detected by enzyme-linked immunosorbent assay and compared between the two groups.ResultsSerum SP levels in patients with acute intussusception were significantly higher than those in controls. However, with recovery of acute intussusception, SP levels gradually decreased after treatment. Serum VIP levels in patients with acute intussusception were significantly lower than those in controls. However, with recovery of acute intussusception, VIP levels gradually increased after treatment.ConclusionsSP and VIP levels may have a potential relationship with the pathogenetic process of intussusception.
