Reduction of Night-time Blood Pressure in Pediatric Renal Transplant Recipients

The proposed study investigated the effect of chronotherapeutic alteration of anti-hypertensive medication on nocturnal hypertension and end-organ injury in pediatric renal transplant recipients who are non-dippers. Additionally, the investigators examined the association between response to intervention, serum adiponectin levels and adiponectin gene polymorphisms. The investigators hypothesized that (1) evening administration of anti-hypertensive medication will convert subjects from non-dipper to dipper status, improve mean nocturnal blood pressure (BP), and improve nocturnal BP load, (2) evening administration of anti-hypertensive medication will reduce albuminuria, left ventricular mass index (LVMI), rate of decline of glomerular filtration rate (eGFR) and will decrease pulse wave velocity (PWV).
