ABO incompatible living donor renal transplantation (ABOi) can achieve outcomes comparable to ABO compatible transplantation (ABOc). However, with the exception of blood group A2 kidneys transplanted into recipients with low titer anti‐A antibody, regimens generally include antibody removal, intensified immunosuppression and splenectomy or rituximab. We now report a series of 20 successful renal transplants across a range of blood group incompatibilities using conventional immunosuppression alone in recipients with low baseline anti‐blood group antibody (ABGAb) titers. Incompatibilities were A1 to O (3), A1 to B (2), A2 to O (2), AB to A (2), AB to B (1), B to A1 (9), B to O (1); titers 1:1 to 1:16 by Ortho. At 36 months, patient and graft survival are 100%. Antibody‐mediated rejection (AbMR) occurred in one patient with thrombophilia and low level donor‐specific anti‐HLA antibody. Four patients experienced cellular rejection (two subclinical), which responded to oral prednisolone. This series demonstrates that selected patients with low titer ABGAb can undergo ABOi with standard immunosuppression alone, suggesting baseline titer as a reliable predictor of AbMR. This reduces morbidity and cost of ABOi for patients with low titer ABGAb and increases the possibility of ABOi from deceased donors.
Pregnancy following renal transplantation is increasingly common. Overall pregnancy outcomes are favourable; however, specific transplant‐related risks do exist. In particular, the risk of caesarean delivery is much higher in renal transplant recipients when compared to the general obstetric population. This is owing to the necessity for preterm delivery in cases of severe and early‐onset pre‐eclampsia and/or fetal growth restriction. We describe two recent cases of renal transplant injury at caesarean delivery at our institution, a tertiary/quaternary obstetric service, which highlight the potential operative risks associated with abdominal surgery. We propose a standardised approach in the care of transplant recipients undergoing caesarean delivery which is aimed at minimising harm and increasing patient safety.
