English BACKGROUND
The ABO blood group is a major determinant in living donor kidney transplantation since AB antigens are expressed on renal tissue. Little attention has been directed to the ABH-secretor status of the donor kidney. As renal tissue is capable of secreting soluble ABH antigens in secretors, we examined the influence of the ABH-secretor status of kidney donors on outcome in ABO-mismatched living donor kidney transplantation.


STUDY DESIGN AND METHODS
We retrospectively analyzed all patients who underwent ABO-mismatched kidney transplantation at the University Hospital Basel from September 2005 to October 2013. The ABH-secretor status was determined in all donors by molecular genetic analysis.


RESULTS
Of all 55 patients who received transplants, we excluded all patients with donor-specific antibodies (n = 4). Forty-one donors were secretors (78%) and 11 were nonsecretors (22%). Recipients of ABH-secretor donor organs showed a significantly higher glomerular filtration rate throughout the first 6 months posttransplant, whereas no significant influence on posttransplant anti-A/B titers was found. Regression analysis revealed a significant impact on humoral rejection, whereas not on vascular or interstitial rejection in protocol kidney biopsies.


CONCLUSION
The donor ABH-secretor status may have an influence on early posttransplant renal function in patients undergoing ABO-mismatched living donor kidney transplantation. Further prospective studies with long-term follow-up are needed to elucidate involved pathomechanisms.
