Abstract

Whether the use of angiotensin-converting enzyme inhibitor or angiotensin receptor blocker inhibitor (ACEI/ARB) is beneficial in renal transplant recipients remains controversial. In this retrospective study on 505 renal transplant recipients, we analyzed blood pressure and graft survival according to antihypertensive treatment with ACE-I/ARB and/or calcium channel blockers (CCB) over a period of 10 years. Patients were stratified according to their blood pressure 1 year after transplantation [controlled (<or=130/80 mmHg; CTR, 181 patients) and noncontrolled (>130/80 mmHg; non-CTR, 324 patients)] and according to antihypertensive treatment (ACE-I/ARB and/or CCB taken for at least 2 years). One year after transplantation, 88.4% of CTR and 96.6% of non-CTR received antihypertensive treatment (P < 0.05). Graft survival was longer in CTR than in non-CTR (P < 0.05). Importantly, graft survival was longer in patients who received long-term treatment with ACEI/ARB, CCB, or a combination of ACEI/ARB and CCB (P < 0.001). The beneficial effect of ACEI/ARB therapy was more pronounced in non-CTR compared with that of CTR. We conclude that blood pressure control is a key target for long-term graft survival in renal transplant patients. Long-term ACEI/ARB and CCB therapy is beneficial for graft survival, especially in patients with diabetes and/or albuminuria.
