The Impact of Human Platelet Antigen Allele on Antiplatelet Antibodies and Cryoglobulins in Patients with Primary Immune Thrombocytopenia and Hepatitis C Virus-Associated Immune Thrombocytopenia. Mediterr J Hematol Infect Dis 2023; 15:e2023030. [PMID: 37180208 PMCID: PMC10171212 DOI: 10.4084/mjhid.2023.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Accepted: 04/20/2023] [Indexed: 05/16/2023] Open
Abstract
Background And Objectives Human platelet antigens (HPAs) are alloantigens associated with antiplatelet alloantibodies and the risk of immune thrombocytopenia (ITP). However, few studies have investigated associations among HPAs, antiplatelet autoantibodies, and cryoglobulins. Methods We enrolled 43 patients with primary ITP, 47 with hepatitis C virus-associated ITP (HCV-ITP), 21 with hepatitis B virus-associated ITP (HBV-ITP), 25 controls with HCV, and 1013 normal controls. We analyzed HPA allele frequencies, including HPA1-6 and 15, antiplatelet antibodies binding to platelet glycoprotein (GP) IIb/IIIa, Ia/IIa, Ib/IX, IV, human leukocyte antigen class I, cryoglobulin IgG/A/M, and their associations with thrombocytopenia. Results In the ITP cohort, HPA2ab, rather than HPA2aa, predicted a low platelet count. HPA2b was associated with the risk of developing ITP. HPA15b was correlated with multiple antiplatelet antibodies. In HCV-ITP patients, HPA3b was correlated with anti-GPIIb/IIIa antibodies. HCV-ITP patients with anti-GPIIb/IIIa antibodies had a higher positive rate of cryoglobulin IgG and IgA compared with those without anti-GPIIb/IIIa antibodies. Overlapping detection was also found among other antiplatelet antibodies and cryoglobulins. Like the antiplatelet antibodies, cryoglobulins were associated with clinical thrombocytopenia, implying their close relationship. Finally, we extracted cryoglobulins to confirm the exhibition of cryoglobulin-like antiplatelet antibodies. In contrast, in primary ITP patients, HPA3b was correlated with cryoglobulin IgG/A/M rather than anti-GPIIb/IIIa antibodies. Conclusion HPA alleles were associated with antiplatelet autoantibodies and had different impacts in primary ITP and HCV-ITP patients. HCV-ITP was considered to be a symptom of mixed cryoglobulinemia in HCV patients. The pathophysiology may differ between these two groups.

[PMID: 35602482 PMCID: PMC9121734 DOI: 10.3389/fmed.2022.873500] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Accepted: 04/14/2022] [Indexed: 11/13/2022] Open
Abstract
Platelet transfusion refractoriness (PTR) is common in patients with hematology and oncology and is becoming an important barrier in the treatment of thrombocytopenia and hemorrhage. Bibliometrics is an effective method for identifying existing research achievements, important breakthroughs, current research hotspots, and future development trends in any given field. In recent years, research on PTR has received increasing attention, but a bibliometric analysis of this field has not yet been reported. In this study, we applied bibliometrics to analyze the existing literature on PTR research over the past 17 years. On November 1, 2021, we began a publications analysis of PTR research using the Science Citation Index Expanded of the Web of Science Core Collection with collection dates from 2004 to 2021. This research aimed to summarize the state of PTR research using Bibliometrix to identify connections between different elements (i.e., authors, institutions, countries, journals, references, and keywords) using VOS viewer analyses to visualize key topics and trends in PTR research using Cite Space and gCLUTO. The results of all 310 studies showed that the annual number of publications focused on PTR is steadily increasing, with the United States of America and Japan making significant contributions. We noted that the research group led by Dr. Sherrill J. Slichter was prominent in this field, while Estcourt Lise may become the most influential newcomer. Transfusion was the most popular journal, and Blood was the most cited journal. Using various analyses, including co-cited analysis, historiography analysis, citation burst analysis, and factorial analysis, we pointed out and discussed contributing publications. According to occurrence analysis, co-word biclustering analysis, landform map, thematic evolution, and thematic map, we believe that “activation,” “p-selection,” “CD36 deficiency,” “gene-frequencies,” “CD109,” “HPA-1,” and “beta (3) integrin” may become new trends in PTR research. The outcome of our bibliometric analyses has, for the first time, revealed profound insights into the current state and trends in PTR research. The systematic analysis provided by our study clearly demonstrates the field's significant advancements to all researchers who are interested in a quick and comprehensive introduction to the field.

Relationship between donor-specific HPA-15 antibodies and poor graft function in HPA-15 mismatched cord blood transplantation. Int J Hematol 2022; 115:753-758. [PMID: 35028883 DOI: 10.1007/s12185-022-03286-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2021] [Revised: 01/06/2022] [Accepted: 01/06/2022] [Indexed: 01/05/2023]
Abstract
Poor graft function (PGF) is a fatal complication following hematopoietic stem cell transplantation and is influenced by multiple factors, such as donor-specific anti-HLA antibodies, a poor infused CD34+ cell count, and the donor source. Alloantibodies against human platelet antigen 15 (HPA-15) recognize platelet membrane glycoprotein CD109, which is expressed not only on platelets, but also on megakaryocytes and specific hematopoietic stem cells. HPA-15 antibodies are known to induce platelet transfusion refractoriness and neonatal alloimmune thrombocytopenia, but their effects on graft function following hematopoietic stem cell transplantation remain unknown. We encountered a case of HPA-15 mismatched cord blood transplantation with a high HPA-15b antibody titer. Prolonged PGF and megakaryocyte aplasia with sustained high-titer HPA-15b antibodies were attenuated by rituximab therapy, and rapid recovery of hematopoiesis was achieved. HPA-15-compatible platelet transfusions were highly effective for platelet recovery. Methylcellulose assays and megakaryocyte cultures revealed that patient serum inhibited in vitro hematopoietic development from patient bone marrow cells. These results suggest that HPA-15 antibodies might be a cause of PGF and that reducing the HPA-15 antibody titer might improve graft function in HPA-15 mismatched transplantation.

Abstract
OBJECTIVE Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a bleeding disease that can cause fetal hydrops, a rare but life-threatening condition in which abnormal amounts of fluid accumulate in one or two areas of the fetus's body. A case of FNAIT with fetal hydrops caused by anti-HPA-15b antibodies was involved in this study, as we investigated whether or not anti-HPA-15b antibodies can induce endothelial angiogenesis and apoptosis. METHODS The monoclonal antibody immobilization of platelet antigens assay (MAIPA) was used to identify anti-HPA-15b antibodies. The three groups in Tube formation and apoptosis assays were the PBS group, the AB serum IgG group, and the anti-HPA-15b serum IgG group, all reacted with HPA-15bb HUVEC. RESULTS The presence of anti-HPA-15b antibodies was found in this case by MAIPA assay. The OD values are 0.33 and 0.21, reacted with HPA-15bb and HPA-15ab platelets, respectively (cutoff OD value = 0.2). Quantitative analysis revealed that the length of capillary-like tube induced by anti-HPA-15b antibodies was significantly decreased over that of AB serum IgG (*p = 0.0005), but weaker than when incubated with thrombin (**p = 0.0009). The apoptosis results show a significantly increased number of apoptotic endothelial cells in the anti-HPA-15b antibody IgG group when compared with the PBS and AB serum IgG groups (*p < 0.0001, **p < 0.0001). In addition, there is no statistical difference between the PBS and AB serum groups. CONCLUSION Anti-HPA-15b antibodies can inhibit angiogenesis and induce apoptosis. This may associate with hydrops fetalis (HF), or fetal hydrops of FNAIT.

Abstract
BACKGROUND Alloantibodies against human platelet antigen (HPA)-15 are sometimes detected in patients with platelet transfusion refractoriness (PTR); however, little is known about their impact on PTR. STUDY DESIGN AND METHODS Two patients who possessed HPA-15 alloantibodies (Patient 1, anti-HPA-15b; Patient 2, anti-HPA-15a) and human leukocyte antigen (HLA) antibodies were enrolled. The efficacy of HPA-15-compatible vs -incompatible platelet transfusion was compared by focusing on ABO- and HLA-matched transfusions on the basis of the 24-hour corrected count increment (CCI-24 hours) for platelets. The titers of HPA-15 antibodies in the patients' sera were also monitored. RESULTS The patients received 71 and 12 ABO-compatible, HLA-matched platelet transfusions, respectively, during the monitoring periods. Among these transfusions, CCI-24 hours could be calculated in 27 and 10 transfusions, respectively, and the HPA-15 genotype of the donors was determined. There were no significant differences in the CCI-24 hours between the HPA-15 compatible and incompatible transfusions in both patients (P = .30 and .56, respectively, Mann-Whitney U test). There was no significant change in the HPA-15b antibody titer in Patient 1 during the monitoring period, while the HPA-15a antibody level in Patient 2 was undetectable at the end of the monitoring period, although the titer was low at the beginning. CONCLUSION The efficacy of HPA-15-incompatible platelet transfusions was not necessarily inferior to that of HPA-15 compatible ones. Although the case number was limited, our results suggest that HPA-15 antibodies do not have a significant impact on the effects of platelet transfusion.

Abstract
BACKGROUND To investigate the related factors influencing immune platelet transfusion refractoriness (PTR) in acute leukemia (AL) from induction to consolidation and compare management for immune PTR, so as to improve the Platelet increment in AL. METHODS The primary analysis included 890 patients with AL, 225 of whom were the immune PTR (25 %).They are patients in our center from induction to consolidation or transplantation in the past 10 years. Flow cytometry, karyotype characteristics and other basic information were compared between the immune PTR vs control (no-PTR) groups. We analyzed the treatment outcomes of immune PTR including matched platelets, intravenous immunoglobulin (IVIG), increasing apheresis platelet does. RESULTS Immune PTR is more likely to occur in patients with poor prognosis in acute lymphoblastic leukemia (ALL) (P = 0.01).There is a relation between NPM1 mutation and occurrence of immune PTR (P = 0.029).The incidence of PTR at 35-59Y was higher than that at <35Y(OR = 0.68, 95 % CI = 0.48-0.96) and ≥60Y(OR = 0.49,95 % CI = 0.28-0.83), and the difference was statistically significant(P = 0.03, P = 0.01).The Platelet increment with 1 unit (u) was 47.12 %, 2 u increased to 71.14 %, and the matched 2 u (75.11 %) had the best effect. IVIG improved the Platelet increment, but there was no difference between 0.4 g/kg IVIG and 1 g/kg IVIG. Immune PTR is more likely to occur in the ages of 35-60 years. CONCLUSION There are specific AL patient characteristics which predispose to the phenomenon of immune based PTR. Meanwhile, increasing the IVIG dose could not improve Platelet increment obviously.

Abstract
BACKGROUND Platelet antibodies can lead to clinical diseases such as platelet transfusion refractoriness (PTR), fetal/neonatal alloimmune thrombocytopenia (FNAIT), etc. This study is aimed at understanding CD36 expression, platelet alloantibody distribution in different populations in Northern China, and effects of platelet alloantibodies on pregnancy. STUDY DESIGN AND METHODS Whole blood samples of 612 subjects including hematological patients, pregnant women, and blood donors were collected at a single center, then CD36 expressions were determined, followed by platelet antibody screening and characterization of platelet antibody specificity. A retrospective analysis was performed in 1552 pregnant women admitted to Department of Obstetrics, in order to investigate FNAIT occurrence. RESULTS Rate of CD36 deficiency expression was 2.12% (13/612), all cases exhibited type II deficiency without type I deficiency being detected, and such rate is lower than that in Southern China (3.43%), Japanese (4.87%) and in the black people (4.18%), and higher than that in the White people (0.09%). Positive rates of platelet antibody screening in hematological patient group (6.86%, 14/204) and in pregnant women group (6.31%, 13/206) are higher than that in blood donor group (0.49%, 1/202), P < .01. Out of 1552 pregnant women, there were not children with FNAIT. CONCLUSION The frequency of CD36 deficiency in northern China was low, all of them were type II deficiency, and no CD36 antibody was detected. It is speculated that the risk of immune-related thrombocytopenia caused by CD36 deficiency in this population is very low. Platelet antibodies should be monitored early in patients with hematological and multiple miscarriages pregnant.

Abstract
Background: Alloantibodies against human platelet alloantigens (HPAs) are responsible for the development of platelet transfusion refractoriness (PTR) in patients receiving random platelets and bleeding disorder in babies with fetal neonatal alloimmune thrombocytopenia (FNAIT). Recently, our results based on the analysis of the allelic distribution of HPAs indicated that immunization may occur among Malay. In this study, we sought to analyze the frequencies of platelet reactive alloantibodies responsible for FNAIT and PTR in Malaysia.Methods: Sera from suspected FNAIT (n = 295) and PTR (n = 74) were collected in five years period (2008-2013) and tested for the presence of platelet reactive antibodies by the use of antigen capture assay.Results: In 5/74 (5.41%) platelet specific antibodies against HPA-2b (n = 1), HPA-5a (n = 1), HPA-5b (n = 1), HPA-15b (n = 2) could be identified in our PTR cohort. In FNAIT cohort, platelet specific alloantibodies could be detected in 18 sera (6.10%) consisting anti-HPA-1a (n = 1), anti-HPA-3a (n = 3), anti-HPA-5a (n = 6), anti-HPA-5b (n = 6), anti-HPA-15a (n = 1), and anti-HPA-15b (n = 1).Conclusion: Our study indicates that anti-HPA-3, -HPA-5 and -HPA-15 antibodies seems to be the most platelet specific antibodies involved in FNAIT and PTR cases in Malaysian population. Since similar HPA allelic distribution among Malaysian and Indonesian populations have been observed, immunization against these three HPA systems are expected to be the most potential risk of alloimmune mediated platelet disorders in Indonesia.
