Abstract

Aim of the work: To assess the carotid artery intima-media thickness (IMT) as an index of subclinical atherosclerosis in patients with primary osteoarthritis (OA) and its correlation to severity and insulin resistance (IR). Patients and methods: This study included 40 primary OA patients (28 with predominant knee OA and 12 with hip OA) and 15 age and sex matched controls. They were subjected to full medical history, thorough clinical examination and radiological assessment by plain X-rays of knee and hip joints scored according to the Kellgren-Lawrence grading. In patients and control, the IR was calculated by the homeostasis model assessment (HOMA) and carotid IMT measured by ultrasonography. Results: There was significant increased carotid IMT in OA patients (0.82. ±. 0.12. mm) compared to controls (0.61. ±. 0.02. mm) (p<. 0.001) with cut-off value of 0.65. mm. There was significant higher HOMA in OA patients (2.55. ±. 0.8) compared to controls (1.79. ±. 0.44) (p<. 0.001). OA patients with IMT. >. 0.65. mm (n= 34) had longer duration (9. ±. 2.56y), higher Kellgren-Lawrence score (2.89. ±. 0.45) and higher HOMA (3.8. ±. 0.53) compared to those patients with IMT. <. 0.65. mm (n= 6) (3.41. ±. 2.09. y, 2.01. ±. 0.26 and 2.23. ±. 0.32 respectively). Multi-regression analysis showed that disease duration, Kellgren-Lawrence Grading and HOMA are the best sensitive discriminators for patients having carotid intima >0.65. mm. (F ratio 36.54, p<. 0.001). Conclusion: Osteoarthritis patients have higher risk of subclinical atherosclerosis independent of traditional risk factors. The severity of OA may contribute to the progression of atherosclerotic disease. Measurement of insulin resistance in OA patients can identify those with higher risk of subclinical atherosclerosis and may help in their follow up and early intervention. © 2013.
