B-type natriuretic peptide and renal function in Japanese patients with type 2 diabetes mellitus: The Dogo Study.

This study included 671 Japanese patients with type 2 diabetes mellitus. BNP levels were divided at quartile points on the basis of the distribution. We used four outcomes regarding the renal function: 1) chronic kidney disease (CKD): estimated glomerular filtration rate (eGFR) < 60ml/min/1.72m(2), 2) advanced CKD: eGFR < 30ml/min/1.72m(2), 3) microalbuminuria: urinary albumin creatinine ratio (UACR) ≥ 30 mg/g creatinine, and 4) macroalbuminuria: UACR ≥ 300 mg/g creatinine. The prevalence values of CKD, advanced CKD, microalbuminuria, and macroalbuminuria were 26.2%, 2.4%, 30.4%, and 9.1%, respectively. Highest BNP (≥ 39.2 ng/ml) was independently positively associated with microalbuminuria and macroalbuminuria (adjusted ORs, 2.81 [95% CI: 1.63-4.89] and 2.82 [95% CI: 1.19-7.12], respectively). High BNP was not associated with advanced CKD or CKD. There was a statistically significant positive exposure-response relationships between the BNP level and advanced CKD, microalbuminuria, and macroalbuminuria (p for trend = 0.025, 0.001, and 0.013, respectively). BNP level may be independently positively associated with advanced CKD, microalbuminuria, and macroalbuminuria but not CKD in Japanese patients with type 2 diabetes mellitus.
