| Abstract | Background: Beta-2 microglobulin (B2M) is considered as a surrogate marker for middle molecule uremic toxins and a key component in dialysis-related amyloidosis. However, few studies have evaluated role of B2M in patients with chronic kidney disease (CKD). Objectives: The purpose of this study was to evaluate the association of plasma B2M level with some metabolic and cardiac performance factors in patients with CKD. Patients and Methods: In this case-control study, we measured plasma B2M level in 86 patients with different stages of CKD and 78 age- and sex-matched individuals, as healthy control group. Then we investigated the association between plasma B2M level and left ventricular hypertrophy, ejection fraction (EF), and left ventricular end-diastolic diameter (LVEDD) in echocardiography and some inflammatory and metabolic factors in patients with CKD. Results: Mean plasma B2M level was significantly higher in patients with CKD than in control group (P < 0.001). It was directly correlated with serum C-reactive protein (r = 0.167, P < 0.001), phosphate (r = 0.112, P < 0.001) levels, and left ventricular mass index (r = 0.438, P < 0.001) and LVEDD (r = 0.275, P < 0.001) in echocardiography. It was also inversely correlated with glomerular filtration rate (r = -0.033, P < 0.001), albumin (r = -0.521, P < 0.001), hemoglobin (r = -0.748, P < 0.001), and EF (r = -0.625, P < 0.001). Conclusions: Our findings suggested that plasma B2M level is inversely associated with GFR and EF and directly correlated with some metabolic and cardiac performance factors. | en |
