Although a relationship with delayed graft function (DGF) has been hypothesized, available data are still scarce and inconclusive.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Methods<\/jats:title>\n<jats:p>A monocentric retrospective observational study was performed on 1127 consecutive KTs from brain death donors over 11 years (2003\u20132013), classified according to their pre-transplant Mean Blood Pressure (MBP) as hypotensive (MBP &lt; 80 mmHg) or normal-hypertensive (MBP \u2265 80 mmHg, with or without effective antihypertensive therapy).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>Univariate analysis showed that a pre-existing hypotension is associated to DGF occurrence (p&lt;0.01; OR for KTs with MBP &lt; 80 mmHg, 4.5; 95% confidence interval [CI], 2.7 to 7.5). Chronic hypotension remained a major predictive factor for DGF development in the logistic regression model adjusted for all DGF determinants. Adjunctive evaluations on paired grafts performed in two different recipients (one hypotensive and the other one normal-hypertensive) confirmed this assumption. Although graft survival was only associated with DGF but not with chronic hypotension in the overall population, stratification according to donor age revealed that death-censored graft survival was significantly lower in hypotensive patients who received a KT from &gt;50 years old donor.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Our findings suggest that pre-existing recipient hypotension, and the subsequent hypotension-related DGF, could be considered a significant detrimental factor, especially when elderly donors are involved
