Abstract
Background. Diabetes mellitus (DM) is a significant predictor of atherosclerosis, cardiovascular disease, and cardiovascular mortality. It is known that atherosclerosis occurs earlier in patients with diabetes, reducing the duration of their life. Leptin as well as other inflammatory markers can contribute to the progression of atherosclerosis in patients with DM, participate in the development of a local inflammatory reaction.
Aim. Determine the cells immunophenotype of atherosclerotic plaques in patients with diabetes.
Materials and methods. We analyzed 24 patients (20 men and 4 women), who underwent aortofemoral bypass, femoral-tibial bypass or carotid endarterectomy. During the operation, a fragment of the arterial wall with an atherosclerotic plaque was obtained for further immunohistochemical studies. Five histologic plaque characteristics (CD68+, α-SMA, CD34, leptin and leptin receptor) were compared.
Results. No difference in the expression of CD68 (p=0.922), α-SMA (p=0.192), CD34 (p=0.858), leptin receptor (p=0.741) and leptin (p=0.610) in atherosclerotic plaques were observed between patients with and without DM. The lack of significant differences between the two groups was possibly due to the small number of observations with DM. In particular, when assessing the expression of selected markers in atherosclerotic plaques, patients with DM showed significantly more leptin receptors than patients without DM (2160.716 and 1205.88 respectively); and also significantly less CD68+ (0.39 and 0.98 respectively) and α-SMA+ (6.5 and 13.5 respectively).
Conclusion. Based on the expression of CD68, α-SMA, CD34, leptin receptor and leptin, no significant differences were observed in atherosclerotic plaque between patients with and without DM. At the same time, despite the limitations of the study (a small number of patients, moderate severity of DM, elderly patients in the DM group), we found a tendency in the increased number of leptin receptors and a decreased number of α-SMA+, CD68+ in DM atherosclerotic plaques. Further study needed, taking into account the limitations of this work.
