Assessment of Increase in Aortic and Carotid Intimal Medial Thickness in Type 1 Diabetic Patients.

AIM

To assess aortic and carotid intima-media thickness (aIMT and cIMT) in diabetic patients.

PATIENTS AND METHODS

The study included 75 type 1 diabetic patients and 30 age and sex matched healthy volunteer. A blood sample was taken for analysis of HbA1 and lipid profile and the urine sample was taken for analysis of albumin/creatinine ratio. aIMT and cIMT via ultrasound were also done.

RESULTS

cIMT & aIMT were significantly higher in diabetics. aIMT was found to be significantly higher than cIMT in diabetic patients (0.72 ± 0.11 vs. 0.52 ± 0.06, P = 0.0001). Ten of our patients (14%) with normal cIMT revealed significantly increased aIMT. aIMT had a significant positive correlation with age of patients, waist/hip ratio & cIMT.

CONCLUSION

Diabetic patients had increased aIMT and cIMT with a relatively greater increase in the aIMT than in the cIMT. Because atherosclerosis begins first in the intima of the aorta, these data suggest that the aIMT might provide the best currently available noninvasive marker of preclinical atherosclerosis in children. We recommend frequent follow up of diabetic patients for early detection of diabetic complication.
