From February 1995 to March 2011, a consecutive series of 526 adult DDKT recipients were analyzed. DRAG values were divided into two groups (negative versus positive years) and then four groups (鈮も垝21,聽鈭?0 to聽鈭?, 0 to 20, and聽鈮?1 years).
Median age of donors and recipients were 39 (range, 1-75) and 41 (range, 18-74) years, respectively. The degree of DRAG was not associated with episodes of allograft rejection. High or low DRAG had no effect on posttransplant serum creatinine levels or estimated glomerular filtration rates. However, negative levels of DRAG, particularly less than聽鈭?0 years, were significantly correlated with superior 10-year death-censored graft survival (86.4% and 83.1% vs 72.2% vs 53.9%; overall P聽= .031), but not increased overall graft or patient survival.
This study demonstrated that DRAG is a prognostic indicator of long-term graft outcomes after DDKT.
