Key result
In patients with chronic kidney disease, carotid intima-media thickness showed significant positive correlations with age (r=+0.332, p=0.003) and BMI (r=+0.294, p=0.008), but not with eGFR.
Why the study?
Carotid artery intima media thickness strongly predicts cardiovascular events, prompting investigation of its correlation with age, body mass index, and glomerular filtration rate in chronic kidney disease.
Do age, BMI, and eGFR correlate with carotid intima-media thickness in patients with chronic kidney disease?

Do age, BMI, and eGFR correlate with carotid intima-media thickness in patients with chronic kidney disease?
In patients with chronic kidney disease stages 3-5, traditional atherosclerotic risk factors like age and BMI correlate positively with carotid intima-media thickness, whereas eGFR does not show a significant independent correlation.
Introduction: Ultrasound measurements of the intima media thickness (IMT) in the carotid arteries is a strong predictor for cardiovascular events both in the general and diseased population. Materials & Methods: This cross-sectional analytic study was conducted to observe correlation of CIMT with age, body mass index (BMI) and glomerular filtration rate (GFR) in chronic kidney disease (CKD). The study was done in Department of Nephrology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh, on 80 chronic kidney disease patients, from July 2014 to June 2015. All the biochemical parameters were measured according to the standard laboratory techniques. Body mass index (BMI) was calculated by person’s body weight divided by height. Glomerular filtration rate (GFR) was calculated using the modification of diet in renal disease (MDRD) formula. CIMT measurement was done by duplex study of carotid vessels through high resolution B-mode ultrasound. Results: Mean age of the patients was 36.1±9.5 years. 20 (25%), 26 (32.5%) and 34 (42.5%) patients were in CKD stage 3, 4 and 5 respectively. Age, serum creatinine and GFR showed statistically significant difference among stage 3, 4 and 5 CKD patients (p<0.001). However, no difference was evident in BMI and mean CIMT among stage 3, 4 and 5 CKD patients. Significant positive correlations were found between age and CIMT (r=+0.332; p=0.003) and BMI and CIMT (r=+0.294; p=0.008). However, no significant correlation was evident with estimated glomerular filtration rate (eGFR) and CIMT (r=–0.181; p=0.109). Conclusion: Age, serum creatinine and estimated glomerular filtration rate showed statistically significant difference among different stages of CKD patients (stage 3, 4 and 5). There were significant positive correlations found in between age and CIMT as well as BMI and CIMT in chronic kidney disease patients, with an exception to GFR and CIMT.

Kaiser et al. (2021) conducted a cross-sectional in chronic kidney disease (CKD) (n=80). Age, BMI, and GFR was evaluated on Correlation of carotid intima-media thickness (CIMT) with age, BMI, and GFR (r=+0.332 for age, r=+0.294 for BMI, p=0.003 for age, 0.008 for BMI). In patients with chronic kidney disease, carotid intima-media thickness showed significant positive correlations with age (r=+0.332, p=0.003) and BMI (r=+0.294, p=0.008), but not with eGFR.
