Sažetak
Advanced glycation process is one of the main pathogenic mechanisms linked to the development of diabetic sequels. The evidence that AGEs have antigenic properties led to a hypothesis that AGE as an antigen continuously formed in a diabetic body may arouse an autoimmune response. The incidence of serum antibodies to AGEs and AGE levels was assessed in 97 IDDM patients and 26 age-matched healthy controls. AGE antibody titer was defined as a ratio of antibody binding to AGE- modified HSA versus binding to unmodified HSA (human serum albumin) using a solid phase ELISA. A purified immunoglobulin fraction from human plasma (1660 healthy donors) of normal subclass distribution was used as a standard. By means of immunoassay, we assessed the antibody ratio and AGE levels in the serum of healthy volunteers (1.27?0.13 ; AGE=14.1?1.9 U/mg ; n=26) (mean?SD), newly-detected IDDM (1.21?0.17 ; AGE=27.7?6.1 U/mg ; HbA1c=12.8?4.4% n=21), IDDM patients with (0.91? 0.2 ; AGE=31.4?7.9 U/mg ; HbA1c=9.4?2.7% n=27) and withouth (1.07?0.2 ; AGE=33.0?7.1 U/mg ; HbA1c=9.5? 3.1% n=27) microangiopathy, and diabetic patients with end stage renal disease (ESRD) (0.81?0.1 ; AGE=24.6?3.8 U/mg ; n=22). In patients with clinically established retinopathy and/or nephropathy the antibody ratio was lower than in patients without complications (0.86?0.2 vs 1.14? 0.2, p<0.001), irrespectively of their glycemic status. The antobody ratio did not correlate with either HbA1c or serum AGEs. Diabetes duration was a major correlating factor (r=0.3, p<0.001), but there was no correlation with age. AGE levels correlated significantly with HbA1c (r=0.6, p<0.001) in all patient groups. These data indicate an autoimmune response of diabetic subjects to the proteins modified by advanced glycation. Long-term presence of both antigens and antigen-specific antibodies might be the cause of a series of undesired phenomena. There is possibility that AGE antibodies form immune complexes, which are believed to have a role in atherogenesis. Therefore, additional studies are needed to establish the role and significance of autoantibodies against AGE in atherogenic processes in diabetes.
