Monocyte count/HDL cholesterol ratio and cardiovascular events in patients with chronic kidney disease

International Urology and Nephrology Aims and scope Submit manuscript

Abstract

Background and aim

Previous studies showed that renal dysfunction was associated with both a reduction in serum high-density lipoprotein (HDL) cholesterol concentration and increased circulating monocyte count. We aimed to investigate the effect of circulating monocyte to serum HDL cholesterol ratio (M/H ratio) on fatal and composite cardiovascular events, in an observational cohort study of chronic kidney disease (CKD) patients.

Materials and methods

A total of 340 subjects with stage 1–5 CKD were followed for a mean follow-up period of 33 (range 2–44) months and assessed for fatal and nonfatal CV events. M/H ratio was calculated for all patients. All-cause mortality and CVE were also analyzed in relation to M/H ratio.

Results

Monocyte/HDL cholesterol ratio was negatively correlated with estimated glomerular filtration rate (eGFR) (r = −0.43, P < 0.001). Notably, both fatal and combined fatal and nonfatal cardiovascular events were more common in patients having a M/H ratio in the third tertile was associated with a hazard ratio of 2.24 and 4.91, respectively, for fatal and composite cardiovascular events compared to being in the first tertile.

Conclusion

Monocyte/HDL cholesterol ratio was increased with decreasing eGFR in predialytic CKD patients. Most importantly, we report for the first time that an increased M/H ratio was cross-sectionally associated with a worse cardiovascular profile and arose as independent predictors of major cardiovascular events during follow-up.
