Background/Aim. Results of studies which have proved an increased inflammatory activity in diabetes type 1, have been published over recent years. One of possible mechanisms that are used to explain chronic inflammation in diabetes is the state of hyperglycemia leading to the enhanced synthesis of glycosylation end products (AGEs) which activate macrophages, increase the oxidative stress and affect the synthesis of interleukins (IL-1, IL-6), tumor necrosis factor-α (TNF-α) and C-reactive protein (CRP). The aim of the study was to determine the inflammatory markers (CRP, IL-6, TNF-α) in patients with diabetes type 1 and to establish their correlation with glucoregulation parameters and other cardiovascular risk factors as well as to compare them with the healthy controls. Methods. The study included 76 patients with diabetes type 1 and 30 healthy controls. We determined values of inflammatory markers (CRP, IL-6, TNF-α) and glucoregulation parameters (fasting glucose HbA1c). Results. The values of CRP (p = 0.014), IL-6 (p = 0.020) and TNF-α (p = 0.037) were statistically significantly higher in the diabetic patients than in the healthy controls. There was a positive correlation between CRP with postprandial glycemia (p = 0.004); the multivariate regression analysis revealed a statistically significant correlation between CRP and age (p = 0.001), smoking (p = 0.055), fasting glucose (p = 0.021) and triglycerides (p = 0.048) as well as between IL-6 and LDLcholesterol (p = 0,009). No statistically significant correlations were found between glycosilated hemoglobin (HbA1c) and the inflammatory markers (CRP, IL-6 and TNF-α). Conclusion. The patients with type 1 diabetes were found to have a low level of inflammatory activity manifested by the increased values of CRP, IL-6 and TNF-α. |
