ABSTRACT
ABO.mismatched transplants are used frequently. Acquired haemolytic anaemia have been reported after ABO mismatched transplantation. Among 214 ABO.unmatched living-donor kidney transplants tS, 10 cases with cyclosporine based therapy developed haemolysis All studied patients had pre-transplant non specific blood transfusion and received kidneys from one haplotype HLA mismatched living donors. There were 164 males and 50 females. while the mean age was 30.41 years. CsA was stopped in patients treated with triple Immunosuppression while the patients received Pred-CsA were switched to conventional immunosuppression 6 patients were transfused with washed O cells and no plasma exchange was required. The prognosis was excellent in 9 patient, and one died from severe haemolysis. The haemolytic anaemia was more frequent among blood group A recipients [60% of our cases] and more severe among recipients with blood group B. Univariate analysis demonstrated significant impact for recipient age. donor sex, number of pretransplant blood transfusions. primary immunosuppression, time to onset of diuresis, recipient and donor blood groups. On the other hand, multivariate analysis restricted the significance to blood group of donor and recipient. time to onset of diuresis and primary immunosuppression. ABO unmatched kindray transplantation had no impact on patient survival, mean while the graft survival appeared to be better among unmatched ABO group in comparison to the same blood group recipients
