Living donor AB0 incompatible kidney transplantation represents a new tool how to improve the access to transplantation. Majority of European protocols are based on desensitization with rituximab, triple drug immunosuppression, intravenous immunoglobulins and specific immunoadsoption (IA) which eliminates isohaemaglutinins. AB0i kidney transplant program was initiated in our centre in 2011 and 21 patients have received grafts from incompatible donors until recently. Highest accepted isohaemaglutinins titers before rituximab were 1 : 64 and corresponding pretransplant immunoadsorption procedures varied from 2 to 9. In 5 patients 1-2 IA procedures were performed also after transplantation. With the advent of paired exchange program the AB0i transplantation is offered to patients with unsuccessful matching run or with aim to improve HLA match between donor and recipient. The main complications were postoperative bleeding and urinary tract infections in patients at risk. Majority of protocol biopsies exhibited positivity of C4d staining. Neither graft loss nor patient death were noticed.
