功能性消化不良患者血清Ghrelin及瘦素水平变化

目的 探讨功能性消化不良(FD)患者血清Ghrelin及瘦素水平变化及其临床意义.方法 60例FD患者,其中餐后不适综合征(PDS)30例,上腹痛综合征(EPS)30例,健康对照者30名,分别采用酶联免疫法和放射免疫法检测血清Ghrelin及瘦素水平.结果 FD组血清Ghrelin水平较对照组明显减低(P<0.01);FD组血清瘦素水平也较对照组明显减低(P<0.05);PDS组血清Ghrelin和瘦素水平较对照组明显减低(P<0.01),且较EPS组明显减低(P<0.01);而EPS组血清Ghrelin和瘦素水平与对照组比较,差异无统计学意义(P>0.05).结论 FD患者血清Ghrelin和瘦素水平减低主要是由PDS患者血清水平改变所致.PDS的病理机制可能主要与胃肠运动异常相关;血清Ghrelin和瘦素在FD发病过程中存在相互作用,对其的检测可能有助于FD分型和指导治疗.

Variation of serum ghrelin and leptin in patients with functional dyspepsia

Objective To investigate the alteration of serum ghrelin and leptin in patients with functional dyspepsia (FD) and their clinical significance. Methods Sixty patients with FD [-30 patients with postprandial distress syndrome(PDS) and 30 patinets with epigastric pain syndrome(EPS)] were enrolled. Thirty healthy subjects were severed as controls. The serum ghrelin and leptin were measured by enzyme linked immunosorbent assay and radioimmunosorbent assay, respectively. Results The concentrations of serum ghrelin and leptin were both significantly lower in patients with FD than in controls (P<0.01). Meanwhile, the concentrations of serum ghrelin and leptin in PDS patients were significantly lower compared with controls (P<0.01) and EPS patients (P<0.01). There was no significant difference in levels of serum ghrelin and leptin between controls and EPS patients(P>0.05). Conclusions The alterations of serum ghrelin and leptin in PDS patients are responsible for their reduction in FD patients. The PDS may he associated with abnormalities in gastrointestinal motility. There is an interaction between serum ghrelin and leptin in development of FD. The detection of serum ghrelin or leptin is helpful in classification and treatment of FD.
