Cardiovascular and renal outcome in recipients of kidney grafts from living donors: role of aortic stiffness

Show Summary Details



Cardiovascular (CV) risk remains high in renal transplant patients despite a clear improvement conferred by transplantation. This risk is attributed mostly to recipient-related risk factors. Donor vascular characteristics, such as arterial stiffness, have been poorly investigated in this regard.


Recipients of living-related (n = 75) and living-unrelated (n = 20) kidney grafts were recruited at a mean time of 107 ± 41 months after transplantation for baseline evaluation and follow-up for the occurrence of the following composite outcome: myocardial infarction, stroke, CV death, doubling of serum creatinine or development of end-stage renal disease (ESRD). At inclusion, recipients and their corresponding donors underwent complete history, physical examination, laboratory tests and non-invasive measurement of aortic pulse wave velocity (PWV).


During a mean follow-up of 56 ± 18 months, 20 recipients doubled their serum creatinine, of whom 16 reached ESRD, and 9 suffered of a new CV event (5 of which were fatal). Cox proportional hazards regression analysis showed that, in addition to recipient-related parameters, such as the presence of CV event and the estimated glomerular filtration rate at inclusion, donor aortic PWV was a strong and independent predictor of the composite recipient outcome.


Donor large artery stiffness may predict recipient CV and graft outcome. This finding demonstrates the tight link that exists between the vascular system and the kidneys and suggests that donor contribution to recipient outcome goes beyond simple parameters like age, gender and even familial or non-familial donor type.
