Prevalence of hypertension in postrenal transplant recipients: A retrospective tertiary care study

Aim: Posttransplant hypertension (HTN) is a strong predictor of patient and graft survival. As there is a paucity of data in India, this retrospective analysis was done to look at the blood pressure (BP) in 506 renal transplant recipients, with 240 males, 266 females, mean age 42.90 ± 13.31 years, looking at their BP, at the initial and after 1 year later. Methods: This is a retrospective tertiary care study looking at serial BP measurements in 506 renal transplant recipients, correlating with their body mass index (BMI), graft function, proteinuria, antihypertensive used, erythropoietin usage, echocardiography native kidney disease, and new-onset diabetes mellitus till 1 year after transplantation. Results: According to the Joint National Committee 7 classification, initial BP was normal in 24 (4.74%), pre-HTN in 145 (28.65%), HTN Stage I in 227 (44.86%), and Stage II in 110 (21.73%) patients. One year later, BP was normal in 43 (8.55%), pre-HTN in 153 (30.26%), HTN Stage I in 236 (46.71%), and Stage II in 74 (14.47%) patients. Diabetics had a higher initial systolic BP (SBP) ( P = 0.005). Patients with left ventricular hypertrophy had a higher SBP 1 year later ( P = 0.001). Patients with BMI > 35 kg/m 2 , had higher initial SBP ( P = 0.01), initial diastolic BP (DBP) ( P = 0.01) and also higher 1 year posttransplant SBP (P = 0.02) and DBP ( P = 0.01). Conclusion: There was a high incidence of HTN in renal transplant recipients, 66.59% patients with HTN and 28.65% with pre-HTN in the initial posttransplant period, and 61.18% with HTN and 30.26% with pre-HTN in the 1-year posttransplant period.
