Abstract:
Background:The pathophysiology of functional dyspepsia(FD)is complicated and unclarified yet. Gastrointestinal hormone dysfunction may contribute to the development of FD. Aims:To investigate the correlation of different subtypes of FD with gastrointestinal hormone motilin(MTL),neuropeptide Y(NPY)and leptin(LEP). Methods:A total of 57 FD patients fulfilling Rome Ⅲ criteria were recruited and divided into epigastric pain syndrome(EPS)group(n = 24)and postprandial distress syndrome( PDS) group( n = 33 ). Ten healthy volunteers were served as controls. Fast and postprandial levels of MTL,NPY and LEP in peripheral blood were detected by radioimmunoassay. Results:Peripheral levels of fast MTL in EPS and PDS groups[(182. 90 ± 108. 57)pg/ mL and(145. 21 ± 67. 18)pg/ mL vs.(224. 47 ± 64. 55)pg/ mL,P < 0. 05],fast NPY in EPS group[(57. 40 ± 28. 75)pg/ mL vs.(90. 75 ± 49. 57)pg/ mL,P < 0. 01], and fast and postprandial NPY in PDS group[fast level:(38. 25 ± 20. 66)pg/ mL vs. (90. 75 ± 49. 57)pg/ mL,P <0. 01;postprandial level:(30. 26 ± 15. 12)pg/ mL vs.(65. 23 ± 54. 42)pg/ mL,P < 0. 01]were significantly lower than those in control group at same time points,especially the PDS group. Fast and postprandial levels of NPY were significantly lower in PDS group than in EPS group at same time points( P < 0. 05). No significant differences were observed in peripheral LEP levels among the three groups at any time points(P > 0. 05). Conclusions:The pathogenic mechanism of FD is related to the level of gastrointestinal hormones,and is different in EPS and PDS subtypes. Reduced MTL and NPY levels might be involved in the pathogenesis of PDS.
