Arterial hypertension is a common complication in children after renal transplantation and the control of hypertension is often difficult. This retrospective investigates the prevalence and rate of control of hypertension using ambulatory blood pressure monitoring (ABPM) in 45 children (mean age 14.1 +/- 4.3 years, mean time after renal transplantation 2.2 +/- 2.7 years), all on cyclosporine or tacrolimus, azathioprine or mycophenolate mofetil plus daily steroids. The overall prevalence of hypertension was 82%. None of the transplanted children had normal blood pressure without antihypertensive therapy (ie, spontaneous normotension). Twenty percent of children had untreated hypertension, 18% had controlled hypertension, and 62% had uncontrolled hypertension. Prevalence of the nondipping phenomenon was 53%. The mean number of antihypertensive drugs (without diuretic monotherapy) in treated patients was 1.9 drugs per patient. The prevalence of arterial hypertension in children after renal transplantation is high and the control of hypertension is often unsatisfactorily low.
