Relationship between plasma adiponectin, visfatin, leptin, and resistin levels and the onset of colonic polyps in prediabetes

Abstract

Objective To explore the relationship between plasma adiponectin, visfatin, leptin, and resistin levels, and the onset of colonic polyps in prediabetes subjects. Methods A total of 468 prediabetes subjects, who received colonoscopy examination, were enrolled in this study, including 248 cases of colon polyps (polyps group with prediabetes) and 220 cases without colonic mucosal lesions (polyps-free group with prediabetes). According to the clinical characteristics of colonic polyps, colonic polyps patients with prediabetes were subdivided into single polyp group, multiple polyps group, low-risk polyps group, and high-risk polyps group, respectively. In addition, 108 subjects with normal glucose tolerance, who were matched with prediabetes subjects on gender and age, were selected as control group, and 46 cases of them were refered to polyps group with normal glucose tolerance and 62 cases were refered to polyps-free group with normal glucose. Plasma adiponectin, visfatin, leptin, and resistin levels were measured in all subjects, and related risk factors of colonic polyps in prediabetes patients were analyzed. Results Not only in normal glucose tolerance subjects, but also in prediabetes subjects, plasma visfatin levels in polyps group were significantly higher than those in polyps-free group (P 0.05), respectively. In addition, in prediabetes subjects, plasma visfatin levels increased (P 0.05). Moreover, plasma adiponectin levels decreased significantly in high-risk polyps group with prediabetes than in low-risk polyps group with prediabetes [(3.7±2.9 vs 7.4±3.5) mg/L, P 0.05). The multivariate logistic regression analysis found that adiponectin was an independent protective factor for colon polyps, multiple colon polyps and high-risk colon polyps. Conclusion The changes of plasma adiponectin levels might be associated with onset of colonic polyps in prediabetes.
