title: Blood pressure determinants in living-related renal allograft donors and their recipients.
abstract: We studied 99 living related allograft donors with follow-up information of at least 10 years and the 50 recipients who had successful outcomes. Recipients were younger and had significantly lower blood pressures at follow-up than their donors. Borderline and definite hypertension were present in 22.2% and 4.0% of donors prior to donation, in 14.4% and 21.1% of donors at follow-up, and in 2.0% and 18.0% of the 50 recipients at follow-up. Age, relative weight, and mean arterial pressure (MAP) prior to donation were the key variables in predicting the follow-up ranked MAP of the donors. CPAH prior to donation was inversely correlated with the age of the donors and, indirectly, with the follow-up MAP. Donor CPAH prior to donation was significantly correlated with the renal allograft function of the recipients but not with the recipient ranked MAP at follow-up. No correlation of the ranked MAP or blood pressure outcome categories between donors and recipients was found. We conclude that donation of one kidney can accelerate the development of hypertension in those donors with predisposition to develop hypertension. In addition, the predisposition of the donors to develop hypertension and their age, within the range observed in the study, does not significantly influence the long-term blood pressure status of the recipient.
