Serum beta2M significant predictor of all-cause and CVD mortality in patients on maintenance hemodialysis
The serum beta2M level may be a significant predictor of the risk of all-cause and CVD mortality in maintenance hemodialysis patients suggests a new study published in the BMC Nephrology
The association between serum β2-microglobulin (β2M) levels and the risk of all-cause and cardiovascular disease (CVD) mortality and the incidence of cardiovascular events (CVEs) in patients undergoing maintenance hemodialysis (MHD) is inconclusive. Furthermore, no study has been performed in China on the significance of serum β2M levels in MHD patients. Therefore, this study investigated the aforementioned association in MHD patients.
In this prospective cohort study, 521 MHD patients were followed at Dalian Municipal Central Hospital affiliated with Dalian University of Technology from December 2019 to December 2021. The serum β2M levels were categorized into three tertiles, and the lowest tertile served as the reference group. Survival curves were calculated by the Kaplan–Meier method. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox proportional hazard models. Sensitivity analysis was performed by excluding patients with CVD at baseline.
