Introduction. Bone mineral density (BMD) was significantly lower in heart failure patients. Our aim was to evaluate the relationship between BMD and fasting serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) concentration in renal transplant recipients. Methods. Fasting blood samples were obtained from 69 renal transplant recipients. BMD was measured by dual energy x-ray absorptiometry in lumbar vertebrae (L2eL4). Serum NT-proBNP levels were measured by electrochemiluminescence immunoassay. Results. Among the renal transplant recipients, 8 patients (11.6%) had osteoporosis and 28 (40.6%) had osteopenia; 33 had a normal BMD. Increased serum NT-proBNP (P < .001) and decreased body mass index (P = .033) and body weight (P = .010) were significantly correlated with low lumbar T-score cutoff points between groups (normal, osteopenia, and osteoporosis). Women had lower lumbar BMD than did men (P = .013). Menopause in women (P = .005), use of tacrolimus (P = .020), and use of cyclosporine (P = .046) among renal transplant recipients were associated with lower lumbar BMD. Multivariate forward stepwise linear regression analysis of the significant variables revealed that logtransformed NT-proBNP (β, -0.545; R2 = 0.331; P < .001), and body weight (β, 0.273, R2 = 0.104; P = .005) were independent predictors of lumbar BMD values among the renal transplant recipients. Conclusions. Serum NT-proBNP concentrations correlate negatively with lumbar BMD values among renal transplant recipients and may be an alternative to energy x-ray absorptiometry for identifying at risk of osteoporosis in renal transplant recipients.
