Recent studies indicate that atherosclerotic process is associated with bone metabolism. The aim of this study was to evaluate carotid intima media thickness (CIMT) and its association with bone mineral density and bone turnover markers as well as inflammation markers in type 2 diabetic male patients.
Material-method: 184 type 2 diabetic males (56±8 y) and 85 non-diabetic control subjects (52±7 y) were recruited. Bone mineral density was measured by dual X-ray absorptiometry at lumbar spine and proximal femoral areas. Carotid intima media thickness was evaluated by Doppler ultrasound. Serum osteocalcin, CTX, intact parathyroid hormone (iPTH), hsCRP and HbA1c were measured.
Results are shown in table 1:
Diabetic subjects | Control subjects | P | |
Serum calcium (mg/dl) | 9.91±0.4 | 9.8±05 | 0.03 |
Serum phosphorus (mg/dl) | 3.59±0.57 | 3.39±0.52 | 0.02 |
Serum PTH (pg/mL) | 49.7±24 | 53±22 | Ns |
Osteocalcin (ng/ml) | 6.8±3.4 | 9.5±4 | 0.0001 |
CTX (ng/ml) | 0.27±0.16 | 0.38±0.1 | 0.004 |
hsCRP (mg/L) | 3.66±4 | 2.11±1 | 0.01 |
HbA1c (%) | 7.02±1.7 | 5.1±0.32 | 0.0001 |
Fasting blood glucose (mg/dl) | 151±65 | 92.62±7.9 | 0.0001 |
Density of Proximal Femur (gr/cm2) | 0.91±0.1 | 0.93±0.1 | 0.4 |
CIMT (mm) | 0.70±0.16 | 0.61±0.23 | 0.008 |
There was a negative correlation between bone mineral content of femur neck and CIMT in diabetic patients (r=−0, 22 P=0.008).
Conclusion: Atherosclerosis and bone mineral density (BMD) may be related through similar or common pathophysiological mechanisms in type 2 diabetics. Low-grade inflammation may be one of the pathologic mechanisms that depressed bone turnover in diabetic patients.
