RESUMEN
BACKGROUND: Mean platelet volume (MPV) is associated with cardiovascular morbidity and mortality in type 2 diabetic patients. However, the effects of blood glucose regulation and treatment regime on MPV has not been adequately studied in type 2 diabetic patients. Aims: We studied the effects of blood glucose regulation and treatment regimen on mean platelet volume in Type 2 diabetic patients. SUBJECTS AND METHODS: A total of 232 diabetic patients who were admitted to the hospital in short intervals of 3 months in the last 2 years were included in the study. When the second admission HbA1c was greater than the first admission HbA1c, they were classified as being in the deteriorated blood glucose regulation group, otherwise they were classified in the improved blood glucose regulation group. Also, the deteriorated and improved blood glucose regulation groups were classified based on therapy modalities as the sulfonylurea + metformin group and the insulin + metformin group. Paired t-test was used for comparison of the groups. RESULTS: Of the 232 patients, 98 (42.2%) were male and 134 (57.8%) were female. There were 126 (55.2%) patients using sulfonylurea + metformin, while 106 (44.8%) patients were using insulin + metformin. MPV levels were significantly increased in patients with deteriorating glucose regulation (p = 0.003). This increase in MPV was only seen in the oral hypoglycemic treatment group (p = 0.003). CONCLUSIONS: Our results suggested a close relationship between poor glycemic control and increased platelet activity in type 2 diabetic patients with oral antidiabetic therapy when compared to the insulin and metformin therapy modality.
