Evaluation of the Impact of Glycemic Control on Mean Platelet Volume and Platelet Activation in Children with Type 1 Diabetes

Abstract

Abstract Objective The studies evaluating cases with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) in the adult population reported hyperreactive platelets and increased activation of prothrombotic factors, resulting in an increased risk of thrombosis. The aim of this study was to evaluate the effects of poor glycemic control and the duration of diabetes on platelet parameters in pediatric population. Methods The study included 366 children, out of which 144 (39.3%) were included in the T1DM group and 222 (60.6%) in the healthy control group. The platelet count, mean platelet volume (MPV), platelet distribution width and plateletcrit values were recorded. The children with T1DM were divided into three groups as per their glycated hemoglobin (HbA1c) levels, good (<7.5%), moderate (7.5–9%) and poor metabolic control (>9%). Results No significant difference in the MPV level between the T1DM (7.41 ± 1.49 fl) and control (7.15 ± 1.23 fl) groups was observed. However, the MPV levels were significantly higher in the poor glycemic control group than in the healthy control group (p = 0.026). Furthermore, as the duration of diabetes and HbA1c levels increased, the MPV levels also increased (p < 0.001, p = 0.441). Conclusion This study suggested as the duration of diabetes and HbA1c levels increased, the MPV levels also increases. Evaluation of hematological parameters can be a cheap and useful method in the evaluation of diabetes regulation in patients with diabetes.
