慢性乙型重型肝炎低血糖患者IGF-1水平及其意义

目的探讨慢性乙型重型肝炎(简称慢重肝)低血糖患者血清胰岛素样生长因子-1(IGF-1)水平及其与空腹血糖(FBG)、空腹胰岛素(INS)、总胆红素(TBiL)、白蛋白(ALB)、凝血酶原活动度(PTA)和呼吸商(RQ)的关系。方法以20例慢重肝低血糖患者为研究对象,20例慢性乙型肝炎(慢肝)患者为对照组,用免疫放射法测定比较2组患者血清IGF-1及INS水平,采用间接测热法应用CCM-D营养代谢测试系统检测2组患者的呼吸商,探讨其与IGF-1水平的关系。结果慢重肝组血清IGF-1水平(11.9±2.6)μg/L明显低于慢肝组(159.8±35.7)μg/L(P<0.01);慢重肝组中晚期IGF-1水平为(8.99±4.61)μg/L,病死率为60%,早期IGF-1水平为(15.43±3.70)μg/L,病死率为20%,2组间中晚期、早期IGF-1水平及病死率差异有统计学意义(P<0.01);慢重肝组INS水平(19.2±10.9)mIU/L明显高于慢肝组(10.6±7.3)mIU/L(P<0.05);慢重肝患者IGF-1<19.03μg/L,提示预后不佳;慢重肝组血清IGF-1水平与ALB、PTA、RQ正相关性(B=0.O45、B=0.O32、B=0.O65,P均<0.05),与INS负相关(B=-0.053,P<0.05),与TBiL、FBG无相关性(B=0.32、B=0.78,P均>0.05)。结论慢重肝患者血清IGF-1水平显著下降,且与病情严重程度有关,提示IGF-1是反映慢重肝患者预后指标之一,且与低血糖发生密切相关。

Detection and Clinical Significance of the Serum Free Insulin-like Growth Factor 1 in Patients with Chronic Severe Hepatitis B and Hypoglycemia

Objective To investigate the changes in serum insulin-like growth factor 1(IGF-1) in patients with chronic severe hepatitis B and hypoglycemia and its relationship to the fasting blood glucose and serum insulin, liver functions and respiratory quotient(RQ). Methods Twenty patients with severe chronic hepatitis B and hypoglycemia and 20 patients with chronic hepatitis B only as the control were recruited. The levels of serum insulin-like growth factor(IGF-1) and the fasting insulin were detected with RIA in ...
