Abstract Background and Objectives Immune platelet refractoriness is a complication of blood transfusion in patients with multiple platelet transfusions. Antibodies against surface antigens, including human platelet antigens (HPAs) and human leukocyte antigens (HLAs), can be produced which can cause the degradation of transfused platelets by macrophages. In this study, the frequency of platele...
Graft failure is a major complication after unrelated cord blood transplantation. Presence of HLA-antibodies before cord blood transplantation may impact graft failure. To analyze the effect of anti-HLA antibodies on unrelated cord blood transplantation outcomes, we analyzed 294 unrelated cord blood transplant recipients after reduced intensity conditioning regimen. The majority of the patients...
Approximately 30% to 40% of patients with acute leukemia receiving repeated pooled random-donor platelet transfusions develop anti-HLA alloantibodies. Over time, however, serum anti-HLA concentrations decrease in approximately 50% of these patients, despite continued exposure to platelet and/or red blood cell transfusions. Using an enzyme-linked immunosorbent assay to measure serum Igs, the pre...
Objectives: Despite the improvements in early-term outcomes of kidney transplantation, late-term graft failure still remained as a critical problem. De novo donor specific antibodies (DSA) developing against direct human leukocyte antigens (HLA) are significant risk factors for shortened survival previously non-sensitized cases. The purpose this study is to evaluate clinical de DSA development ...
The presence of donor human leukocyte antigen (HLA)-specific antibodies has been shown to be associated with graft loss and decreased patient survival, but it is not uncommon that donor-specific HLA antibodies are absent in patients with biopsy-proven antibody-mediated rejection. In this review, we focus on the latest findings on antibodies against non-HLA antigens in kidney and heart transplan...
BACKGROUND AND PURPOSE Multiple platelet transfusions may induce alloimmunization. Platelet alloimmunization involves human leukocyte antigen (HLA) antibodies and platelet-specific antibodies, which recognize platelet glycoproteins. No data are available about the frequency and characteristics of platelet-specific antibodies in patients who have received multiple platelet transfusions in Taiwan...
The non-donor-specific anti-HLA-Ia antibodies correlate significantly with lower graft survival in organ transplant patients. Based on our earlier findings that anti-HLA-E murine monoclonal antibodies (MEM-E/02 and 3D12) reacted with different HLA-Ia alleles and the peptides shared by HLA-E and HLA class, Ia alleles inhibited the HLA-Ia reactivity of the anti-HLA-E antibodies in normal non-allo...
UNLABELLED Antibodies against donor's HLA antigens and B cell activity are recognized modulators of immune response to allograft. The role of both anti-HLA and non-HLA antibodies is understood in solid organ transplantation, but has not been addressed in composite tissue allografts. AIM We decided to evaluate the presence and role of anti-HLA and non-HLA antibodies after hand transplantation....
Autoimmune hepatitis (AIH) can arise de novo after liver transplantation (LT) for non-autoimmune liver diseases. Considering the identical features of de novo AIH after LT and classical AIH, as well as the importance of anti-human leukocyte antigen (HLA) antibodies in graft rejection, we investigated the presence of circulating anti-HLA class II antibodies in the sera of 35 patients with AIH, 3...
We explored the association between HLA-B and HLA-DRB1 polymorphisms reviewed clinical characteristics of systemic lupus erythematosus (SLE) in Han population Yunnan, China. Methods There were 295 patients 265 healthy control subjects (HCs) enrolled study. Clinical data blood samples collected from patients. The genotypes detected SLE HCs. Results A total 74 on loci determined 288 as well 57 re...
