Brief Summary

Hypertension (HTN) affects up to 75% of kidney transplant recipients and is associated with premature death. Nocturnal HTN is a common complication of ongoing essential HTN or a secondary cause of HTN. Both the non dipping of systolic blood pressure (SBP) at night time and the reverse dipping is associated with increased target organ damage and adverse cardiovascular outcomes and possibly allograft survival. Treatment of Nocturnal HTN is critical. Chronotherapy has been shown to be effective in halting progression in patients with diabetic nephropathy and chronic kidney disease. There is not enough data on prevalence and management of nocturnal HTN in transplant patients, which is the object of this study.

chronotherapy

EXPERIMENTAL

Patients identified with Nocturnal Hypertension, will have one of the blood pressure medications switched from daytime dosing to nighttime dosing

Drug: Chronotherapy

Interventions

Patients identified with nocturnal hypertension while treated with blood pressure medications will have one medication switched from daytime to night time dosing in the following preference: 1. ACE or ARB 2. Calcium Channel Blockers 3. Alpha Blocker 4. Beta Blocker If patient is on only one daytime BP medication, it will be switched to night time dosing. No dose adjustments will be made nor any new medications will be added. Only timing of BP medication will be changed.
