摘要
目的探讨低渗非离子型造影剂对2型糖尿病(T2DM)及Ⅰ~Ⅲ期糖尿病肾病(DN)患者肾功能的影响。方法选择2011年9月—2013年8月在广西医科大学第一附属医院行肾脏CT灌注成像检查的患者50例,其中T2DM及Ⅰ~Ⅲ期DN患者25例(观察组),健康志愿者25例(对照组)。观察两组受试者造影剂肾病(CIN)发生情况,灌注前及灌注后第1、3天空腹血糖、24 h尿微量清蛋白、24 h尿蛋白定量、血尿素氮、血肌酐、血尿酸、估算肾小球滤过率(C-GFR)及造影相关并发症情况。结果两组受试者均未发生CIN。两组间比较,空腹血糖、24 h尿微量清蛋白、24 h尿蛋白定量、血尿素氮、血肌酐及C-GFR间差异均有统计学意义(P〈0.05),血尿酸间差异无统计学意义(P〉0.05);组内比较,除空腹血糖、血尿酸差异有统计学意义外,余指标差异均无统计学意义(P〉0.05)。两组受试者均未发生造影相关并发症。结论 T2DM及Ⅰ~Ⅲ期DN并非肾脏CT灌注成像检查的绝对禁忌证,在做好病例筛选及充分水化治疗的基础上,采用低渗非离子型造影剂对其进行肾脏CT灌注成像检查是比较安全的,对患者肾功能无明显影响,不会增加CIN发生风险。
Objective To investigate the effect of hypotonic non-ionic contrast agents on renal function in patients with type 2 diabetes mellitus(T2DM) or stageⅠ-Ⅲ diabetic nephropathy(DN).Methods From September 2011 to August2013,25 patients with T2DM or stageⅠ-Ⅲ DN(study group),25 healthy subjects(control group) underwent CT perfusion imaging of kidney.The incidence of contrast-induced nephropathy(CIN),fasting blood glucose(FBG),24 h urine albumin,24 h urine protein quantitation(UPQ),blood urea nitrogen(BUN),creatinine(Cr),uric acid(UA),estimated glomerular filtration rate(C-GFR) and contrast-related complications were observed before infusion and on days 1,3 after infusion.Results CIN did not occurred in 2 groups.There was significant difference in FBG,24 h urine albumin,24 h UPQ,BUN,Cr,C-GFR between 2 groups(P〈0.05),there was no in UA(P〉0.05).In intra-group comparison,there was no difference in all indicators except in FBG,UA(P〉0.05).No contrast-related complication occurred in 2 groups.Conclusion T2DM and stage Ⅰ-Ⅲ DN are not absolute contraindications of renal CT perfusion imaging.Based on patients' screening and adequate hydration therapy,hypotonic non-ionic contrast agents is safe without obvious effects on patients' renal function,not to increase CIN risks.
