Abstract:
Objective To investigate the clinical value in changes of serum glutamic acid decarboxylase antibody (GAD-Ab) ,islet cell antibodies(ICA) ,insulin autoantibodies (IAA) and high-sensitivity C-reactive protein (hs-CRP) and renal function in elderly type 2 diabetic patients .Methods 122 cases of endocrine inpatient in our hospital had been diagnosed with type 2 diabetes were chosen from January 2012 to December 2012 .They were divided into islet autoimmunity antibody positive group (n=21) and islet autoimmunity antibody negative group (n=101) according to the antibody test results ,Fasting C-peptide(FCP) ,2-hour postprandial C-peptide(2 h CP) ,glycosylated hemoglobin(HbA1c) ,high-sensitivity-CRP(hs-CRP) and renal function[urea (UREA) ,creatinine (Cr) ,microalbuminuria(urinary mALB) ,urinary β2-microglobulin (urinary β2-MG)]were detected .Test results were statistically analyzed and compared .Results At least one Islet autoimmune antibodies were found in 21 cases of 122 elderly patients with type 2 diabetes .The positive rate was 17 .21% .GAD-Ab was detected positive in 14 cases(11 .47% ) ,ICA was detected positive in 10 ca-ses(8 .19% ) ,IAA was detected positive in 1 case(0 .82% ) ,Two antibodies were detected positive together in 4 patients(3 .27% ) , Three antibodies were not detected positive together .The levels of hs-CRP ,UREA and Cr in Islet autoantibodies positive group were higher then in islet autoimmunity antibody negative group ,the difference was statistically significant (P<0 .05) .The levels of FCP ,2 h CP ,HbA1c ,urinary mALB and urinary β2-MG in both group ,the difference was not statistically significant (P>0 .05) . Conclusion Chronic inflammation and the appearance of islet autoantibodies are closely related to the damage of islet cell function . It has a higher value in monitoring complications and efficacy through understanding islet autoantibodies ,inflammation and changes in renal function in elderly type 2 diabetes .
