目的
2
通过对维持性血液透析患者血清胆汁酸谱的靶向定量检测,探讨终末期肾病(end-stage renal disease,ESRD)胆汁酸谱的变化与代谢并发症及预后的关系。
方法
2
收集2013年12月至2016年12月重庆医科大学附属第二医院77例维持性血液透析患者(ESRD组)及本院体检中心30名健康对照(HC组)的血液标本,采用超高效液相色谱-串联质谱方法对其进行血清胆汁酸的靶向定量检测。结合单变量与多变量统计分析对终末期肾病患者与健康对照进行胆汁酸谱的差异分析。
结果
2
检测出6种胆汁酸在组间差异具有统计学意义,其中ESRD组鹅脱氧胆酸、脱氧胆酸、胆酸水平明显降低,甘氨鹅脱氧胆酸、牛磺鹅脱氧胆酸、甘氨胆酸水平明显升高(
P
<
0.05)。亚组分析提示牛磺胆酸、牛磺鹅脱氧胆酸、牛磺猪胆酸、牛磺α鼠胆酸水平在健康对照、终末期肾脏病存活组及死亡组呈逐渐升高趋势,差异具有统计学意义(
P
<
0.01)。
结论
2
终末期肾脏病胆汁酸代谢紊乱与脂代谢异常及不良预后有关。
Objective
2
To explore the association of serum bile acid profile with metabolic complications and outcomes in patients with end-stage renal disease (ESRD) on maintenance hemodialysis.
Methods
2
Between December
2013 and December
2016
77 patients with ESRD on maintenance hemodialysis and 30 healthy subjects were recruited from the Second Affiliated Hospital of Chongqing Medical University. Fasting blood samples were collected from all the subjects
and a targeted metabolomics approach based on ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was used to determine the changes in serum bile acids between the ESRD patients and the healthy subjects. Univariate and multivariate analyses were performed to screen the differential bile acids between the two groups.
Results
2
Six differential bile acids were identified as probable biomarkers for differentiation between ESRD patients and healthy subjects. The levels of chenodeoxycholic acid
deoxycholic acid
and cholic acid were significantly decreased
and the levels of glycochenodeoxycholic acid
taurochenodeoxycholic acid
and
glycocholic acid were significantly increased in ESRD patients(
P
<
0.05). Subgroup analyses suggested that the levels of taurocholic acid
taurochenodeoxycholic acid
taurohyocholic acid
and tauro α-muricholic acid all increased significantly and progressively in the order of the healthy control group
ESRD survival group
and ESRD death group(
P
<
0.01).
Conclusion
2
The serum bile acid profile of ESRD patients is significantly different from that of healthy subjects
suggesting the association of bile acid metabloism disorder with the occurrence of dyslipidemia and a poor prognosis of ESRD.
