ALTERATION OF SEROTONIN POSITIVE CELLS IN COLONIC MUCOSA OF PATIENTS WITH INFLAMMATORY BOWEL DISEASE

摘要

BACKGROUND AND AIMS: THERE HAVE BEEN DESCRIBED INCREASED MUCOSAL DENSITIES OF SEROTONIN POSITIVE NEUROENDOCRINE CELLS IN INFLAMMATORY BOWEL DISEASE (IBD) . THE AIM OF OUR STUDY IS TO DETERMINE THE SEROTONIN POSITIVE NEUROENDOCRINE CELLS DENSITIES IN COLONIC MUCOSA OF PATIENTS WITH IBD. METHODS: COLONIC BIOPSIES FROM 18 PATIENTS WITH IBD ( 8 ULCERATIVE COLITIS, 10 CHRON’S DISEASE) AND 16 HEALTHY CONTROLS WERE EVALUATED HISTOPATOLOGIC WITH HEMATOXYLINEOSIN AND IMMUNOHISTOCHEMICAL WITH SEROTONIN ANTIBODIES. RESULTS: NE CELLS POSITIVE FOR 5-HT WERE COUNTED ON A TOTAL MEDIAN NUMBER OF 20.7 (1,80) CRYPTS IN IBD GROUP AND 25.65(2,64) CRYPTS IN CONTROLS. THE TOTAL DENSITIES/SUBJECT OF 5-HT POSITIVE CELLS WERE SIGNIFICANTLY HIGHER IN IBD GROUP COMPARED TO CONTROLS: 0.56(0.11,1.87) FOR IBD GROUP AND 0.28(0.14,0.71) FOR CONTROLS, P=0.004. CONCLUSION: OUR STUDY SHOWED AN INCREASED DENSITY OF SEROTONIN POSITIVE NEUROENDOCRINE CELLS IN IBD COLITIS WHEN COMPARED TO HEALTHY CONTROLS.
