摘要
目的:比较分析不同胰岛功能指标在胰岛素瘤和胰岛素自身免疫综合征(IAS)中的诊断价值。方法:回顾性分析我院2005年1月-2019年3月明确诊断的胰岛素瘤和IAS病例,比较分析胰岛素(INS)、胰岛素释放指数(IRI)、胰岛素释放修正指数(修正IRI)、C肽、C肽释放指数(CPI)、C肽释放修正指数(修正CPI)、胰岛素/C肽在两组诊断价值以及低血糖发作时胰岛素与C肽相关性研究。结果:胰岛素瘤组24例,IAS组9例,各指标在胰岛素瘤组和IAS组中均有差异。IAS组INS、IRI、修正IRI、C肽、CPI、修正CPI、胰岛素/C肽都高于胰岛素瘤组(均P<0.01)。低血糖发作时,IAS组INS与C肽之间相关性不显著,在胰岛素瘤组中相关性为0.695(P<0.01)。结论:利用各胰岛功能指标在胰岛素瘤和IAS中的差异表达,有助于提高胰岛素瘤和IAS在临床中的鉴别诊断。
Objective:To evaluate the diagnostic value of different islet function indices in insulinoma and insulin autoimmune syndrome(IAS).Methods:The clinical date of patients with insulinoma and insulin autoimmune syndrome were retrospectively analyzed from January 2005 to March 2019.The diagnostic value of insulin(INS),insulin release index(IRI),amended IRI,C-peptide,CPI,amended CPI,insulin/C-peptide in insulinoma and IAS were compared and the relationship between insulin and C-peptide during hypoglycemia were compared.Results:There were 24 cases in insulinoma group and 9 cases in IAS group,each index had significant differences between the two groups.The data of two groups showed that the expression level of insulin,insulin release index,amended IRI,C-peptide,CPI,amended CPI,insulin/C-peptide of the IAS group were higher than those in the insulinoma group(all P<0.05).There was no significant correlation between INS and C-peptide in IAS group when hypoglycemia,and the correlation in insulinoma group was 0.695,P<0.01.Conclusion:The differential expression of various islet function indexes in insulinoma and IAS is helpful to improve the differential diagnosis of insulinoma and IAS.
