Diurnal blood pressure variation in kidney-pancreas transplant recipients.

Abstract：

:Blood pressure normally follows a characteristic pattern throughout the 24 h cycle with daytime pressures higher than nighttime pressures. Patients lacking a nocturnal decrease in pressure have a higher incidence of end organ damage. This investigation was designed to characterize the diurnal pattern of blood pressure and to evaluate blood pressure load in patients who have received a combined kidney-pancreas (KP) transplant. Ten patients (mean 10 months posttransplant) underwent 48 h of noninvasive ambulatory blood pressure monitoring using a commercially available device (SpaceLabs 90202 or 90207). Blood pressure was measured every 15 min from 6 AM to 9 PM and every 30 min from 9 PM to 6 AM. Ambulatory monitoring revealed a markedly increased nocturnal blood pressure (up to 25% greater than daytime pressures). These patients were found to have a higher nocturnal blood pressure load than during the day. No relationship was demonstrated between diurnal blood pressure variation and immunosuppression regimen, elapsed time after transplantation, or antihypertensive treatment. These results indicate that close attention must be given to the nocturnal blood pressure of KP recipients and suggest that standard antihypertensive medication regimens do not adequately treat the nocturnal hypertension in these patients. This may predispose these patients to further cardiovascular or cerebrovascular complications.
