Hypertension developing after transplantation is characterized by widespread vasoconstriction including the kidney. Late resolution (mean, 29 ± 4 months) of posttransplant hypertension has been observed in 15 (Group I) of 278 subjects monitored after liver transplantation. These studies were undertaken to define the systemic and renal changes associated with resolution, as compared with a group matched for age, sex, and time after transplant who remained hypertensive (Group II; N= 15) or a group who never developed hypertension (Group III; N = 23). Blood pressure during resolution paralleled changes in the systemic resistance index, which fell from 3,052 ± 548 to 1,872 ± 205 dyne/s·cm5/m2 (P < 0.01). GFR and RBF remained low, despite the resolution of hypertension, and renal vascular resistance did not change. Circulating endothelin levels remained above normal in all transplant recipients (Group I, 11.9 ± 3.0 versus normal subjects, 7.0 ± 1.1 pg/mL; P < 0.05), and urinary prostacyclin excretion was suppressed (880 ± 120 versus 2,247 ± 187 ng/day; P < 0.01). No hormonal differences were apparent between transplant groups. These results demonstrate the capacity for systemic vasodilation to occur after transplantation, independent of vascular tone in the kidney. They further suggest that renal vasoconstriction and impaired GFR alone are not sufficient to explain de novo hypertension after transplantation.
