FREQUENCY OF ASPIRIN RESISTANCE IN PATIENTS WITH TYPE 1 AND 2 DIABETES MELLITUS AND ITS ASSOCIATION WITH METABOLIC PARAMETERS

Objectives: In the present study, we aimed to determine the prevalence of aspirin resistance in patients with Type 1 and 2 diabetes and to study its association with metabolic parameters. Methods: Aspirin resistance of patients (n=158) with Type 2 Diabetes Mellitus (DM) who presented to the center after 7 days of regular aspirin use were compared to age-mathced (55±19) healthy controls (n=164). Similarly, aspirin resistance of patients (n=30) diagnosed with Type 1 DM were compared to age-matched (27±7) healthy subjects (n=41) as the control group. Platelet Function Analyzer (PFA)-100 was used to evaluate the efficacy of aspirin. Results: Aspirin resistance was identified in 72 of 158 patients with Type 2 DM (45.6%) and in 47 of 164 healthy controls (28.6%) (p=0.001). Aspirin resistance had a prevalence of 50% in patients with Type 1 DM and was significantly higher compared to the control group of 41 healthy subjects (12.2%) (p=0.001). No correlations were noted between aspirin resistance and sex, smoking, HbA1c, hypertension and aspirin dose. There was a significant relation between aspirin resistance and LDL-cholesterol in patients with Type 2 DM (p=0.020). Conclusion: Patients with Type 1 and Type 2 DM had a higher frequency of aspirin resistance than the control group. Therefore, treatment choices including administering higher doses of aspirin or using other antiplatelet agents such as clopidogrel should be considered to prevent thrombocytic events in diabetes mellitus.
