Abstract

The aim of the current study was to evaluate risk factors associated with hypertension in kidney transplant recipients. The authors recruited 92 consecutive kidney transplant recipients and 30 age-matched patients with chronic kidney disease without history of cardiovascular events. Twenty-four-hour ambulatory blood pressure monitoring, pulse wave velocity, and carotid ultrasound were performed. Serum levels of log-transformed interleukin 6 (Log IL-6), soluble tumor necrosis factor receptor 2, and intercellular adhesion molecule 1 were determined. Twenty-four-hour systolic blood pressure (SBP) (P=.0001), Log IL-6 (P=.011), and total number of carotid plaques (P=.013) were higher, while the percentage decline of SBP from day to night was lower in kidney transplant recipients (P=.003). Independent predictors of 24-hour SBP were urinary protein/creatinine ratio and circulating monocytes (P=.001), while Log IL-6, serum creatinine, and total number of carotid plaques (P=.0001) were independent predictors of percentage decline of SBP from day to night. These results suggest that subclinical atherosclerosis and systemic inflammation are associated with hypertension after transplantation.
