ABSTRACT
To determine the serological levels of inflammatory markers and autoimmunity in patients with T1D compared with controls, and determined its relation to the duration of diabetes. Methods: We selected 139 patients with T1D without chronic complications of diabetes, and 110 control subjects without family history of diabetes. Serological ultrasensitive C-reactive protein levels (usCRP), interleukin- 6 and adhesion protein VCAM through ELISA assay were determined. Autoimmune profile was also analyzed through GAD65, IA-2 and ZnT8 autoantibodies. Results: Increased levels of usCRP 1.74 (0.10 to 13.6) vs 1.08 (0.40 to 3.70) ng/ml (p < 0.03), VCAM 236.0 (122.2 to 693.5) vs 185.4 (101.3 to 421.3) ng/ml, p < 0.02 and IL-6 1.73 (0.40 to 9.10) vs 1.28 (0.30 to 4.60) ng/ml, p < 0.05 was found in the group of T1D patients compared with the control group. When analyzing inflammatory markers according to age groups (0-10 years and > 10 years), the values of usCRP were higher in the second group. There was no significant association between patients with DM1 and autoimmune positive profile with a higher frequency of markers of inflammation. Conclusions: These results suggest the presence of pro-inflammatory state is considerably more frequent in patients with T1D. The increased level of usCRP and IL -6 and according to age of the patients could indicate a possible role of adiposity and weight gain during the adolescence in the higher frequency of inflammatory markers in T1D patients...
