Studies conducted in patients with end-stage renal disease (ESRD) showed that calcification in vascular structures is an important component of the atherosclerosis process. GLA rich protein (GRP) has been suggested as a potential marker for vascular calcification. We investigated the relationship between GRP levels, carotid intima media thickness and inflammatory parameters in patients with predialysis stage 3, 4 and 5 CKD.Material and Methods: A total of 106 patients aged ≥ 18 years with CKD stage 3, stage 4 and non-dialysis stage 5 and 25 healthy volunteers were enrolled in the study. Patients with obesity, uncontrolled hypertension, coronary artery disease, with active cancer or liver disease, malignant hematologic disorders, acute renal failure, acute or chronic infections were excluded. As the control group, healthy volunteers without any known illness, regular drug use, smoking, alcohol use, and obesity were recruited.Results: Patients were divided into two groups as those with CIMT below 0.90 mm and those with CIMT 0.90 mm and above. There was no significant difference between the two groups in terms of the presence of HT and DM. While the CRP values of the group with high CIMT were found to be significantly higher (p=0.005), the GLA rich protein levels of this group were found to be significantly higher (p=0.019).Conclusion: In our study, it was determined that there was a positive correlation between GRP levels and CIMT in patients with predialysis CKD, and GRP levels were higher in patients with CIMT above 0.90 mm. These findings suggest that GRP levels can be used as a cardiovascular event biomarker in patients with CKD.Keywords: chronic kidney disease, carotid intima media thickness, inflammation, GLA rich protein
