HYPERTENSION IN RENAL ALLOGRAFT RECIPIENTS

Objective To further evaluate the effect of hypertension on renal graft function, and the relationship between hypertension, hyperlipoidemia and ischemic heart disease. Methods 102 renal transplant recipients with a functioning renal graft for more than 1 year were enrolled in this study. Renal function was followed for the further 24 months. Results The overall prevalence of hypertension was 89.2%(91/102) and 36.2%(33/91) hypertensive patients had uncontrolled blood pressure. After 24 months those with high blood pressure had significantly higher Scr levels than normotensive patients (P<0.05). The number of different antihypertensive classes required was related to Scr (P<0.05). Plasma cholesterol levels in hypertension patients especially in blood pressure uncontrolled group were significantly elevated (P<0.01). Ischemic heart disease was more common in hypertensive patients (P<0.05). Cyclosporine A was associated with hypertension more frequently than azathioprine and FK506, whereas low-dose prednisolone did not appear to influence blood pressure. Conclusion The data further confirmed that hypertension was associated with hyperlipidemia and ischemic heart disease, and emerged as a predictor of renal graft dysfunction. Whether cyclosporine A should be converted to new immunosuppressive agents and which class of antihypertensive medication is more effective in this population remain open questions.
