Among these patients, 8 rejected the transplant while 10 had complete donor chimerism (CC). Five out of 8 patients (62.5%) who rejected graft had anti-HLA antibodies in the sera collected before transplant, while only 1 patient out of 10 (10%) with CC showed their presence (p=0,042). Notably, of the 5 HLA antibodies positive patients who rejected the graft 3 had DSA (2 for class I and 1 for class I and II) while none of the patients with CC had DSA. Among the 8 patients that experienced graft failure 4 were transplanted with a donor characterized by the lack of NK alloreactivity and 5 with a donor with a B content value <2. Although we analyzed a small cohort of patients, our data indicated that the presence of anti-HLA antibodies in patient sera, but not donor KIR characteristics, correlates with graft failure thus suggesting that analysis of anti-HLA antibodies should be taken into account in haploidentical transplant setting. </strong>}, number={1}, journal={Mediterranean Journal of Hematology and Infectious Diseases}, author={Andreani, Marco and Testi, Manuela and Sodani, Pietro and Troiano, Maria and Di Luzio, Andrea and Testa, Giuseppe and Falco, Michela and Poggi, Elvira and Gaziev, Javid and Piazza, Antonina}, year={2017}, month={Mar.}, pages={e2017020} }
