Is There Any Difference in the Plasma Homocysteine Levels of Diabetes Mellitus Type Ii Patients, Impaired Glucose Tolerance Subjects and Normal People?

Introduction: Hyperhomocysteinemia is associated with an increased risk of cardiovascular disease in diabetic patients. The aim of this study was to determine plasma homocysteine levels in diabetics and compare with control persons and also evaluation of correlation between plasma homocysteine concentration and diabetic related variables. Methods: This study was done on 39 type II diabetic patients, 27 subjects with impaired glucose tolerance and 23 normal persons referring to Endocrine and Metabolism Research Center of Medical university of Isfahan. Physical characteristics were recorded. After an overnight fast, a blood sample was drawn for determination of FPG, HbA1c – homocysteine, Cr. Cholesterol – Triglyceride and HDL- Cholesterol. Mean plasma homocysteine levels in the groups were compared by one way ANOVA. The Correlation of different parameters was tested by Pearson’s correlation. Results: There was no statistically significant difference in the plasma homocysteine levels of all the groups.(P=0.71). Correlation between homocysteine levels and HbA1c was not significant (P=0.42) in diabetic patients. Conclusions: The findings suggest that diabetes does not influence plasma homocysteine levels.Also, there is no correlation between plasma homocysteine levels and HbA1c in diabetic patient
