Predominance of nocturnal hypertension in pediatric renal allograft recipients

: Hypertension is common in children with end‐stage renal disease who have undergone renal transplantation. We performed ambulatory blood pressure monitoring (ABPM) in renal allograft recipients who were on stable maintenance immunosuppressive medications and were more than six months post‐transplant. Echocardiographic measurement of left ventricular mass index (LVMI) was obtained at the time of ABPM. Twenty‐nine children with a mean age of 14.8 yr (8–18 yr) were evaluated 4.3 yr (0.6–12.8 yr) after deceased donor (n = 13) or living donor (n = 16) transplantation. BP levels were higher during sleep compared with when awake using the 95th percentile to standardize mean BP for each period: mean BP was expressed as a standard deviation score (SDS) for each time period, awake vs. sleep: systolic (s) BP SDS were 0.43 ± 1.3 vs. 1.29 ± 1.2 (p
