We thank Dr Balta and colleagues1 for their interest in our work, and would like to respond to their recent article. 2 We agree concerning the importance of investigating the pathological status in patients with masked hypertension (MHT), including inflammation markers. We reanalyzed the association between endothelial dysfunction (ie, the flow-mediated vasodilation [FMD] magnitude [DFMD] and the integrated FMD response [FMD-AUC120]) and other pathological status. We also measured the urinary albumin-creatinine ratio (UACR) in our studies3, 4 (Table). The UACR in the patients with sustained hypertensive (office blood pressure [BP]≥ 140/90 mm Hg and home BP≥ 135/85 mm Hg) was significantly higher than that among both the patients with white-coat hypertension (office BP≥ 140/90 mm Hg and home BP< 135/85 mm Hg) and the patients with normotension (office BP< 140/90 mm Hg and home BP< 135/85 mm Hg). The differences in UACR in the MHT group and those in the normotensive patients were not statistically significant, but the underlying reason might be a type II error. This finding was similar to that obtained in our previous study. 5 FMD-AUC120 was significantly inversely associated with log UACR (r= À0. 18, P=. 008), but DFMD was not associated with log UACR (r= À0. 06, P=. 35). FMDAUC120 reflected kidney disease, but DFMD did not. The UACR was significantly higher in the patients in the lowest tertile for FMD-AUC120 (FMD-AUC120< 5.0 mmxs, n= 86) than in the patients in the highest tertile for FMD-AUC120 (FMD-AUC120≥ 11.0 mmxs, n= 86 [P<. 001]; Figure, panel A), but the UACR was similar in the patients in the lowest and highest tertiles for DFMD (P= 1.0; Figure, panel B). We did not evaluate sedentary habits or liver function. We measured the high-sensitivity CRP (hsCRP) level, but log-hsCRP was not associated with DFMD or with FMD-AUC120.As Dr Balba commented, 1 endothelial dysfunction, which was measured as FMD (not DFMD, but FMDAUC120), might be associated with kidney disease. However, in our patient population, there was no association between FMD and inflammation. We previously demonstrated that FMD-AUC120 was associated with the Framingham risk score, 3 and further studies
