HLA peptide-binding pocket diversity modulates immunological complications after cord blood transplant in acute leukaemia. Br J Haematol 2024; 204:1920-1934. [PMID: 38380743 DOI: 10.1111/bjh.19339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 01/23/2024] [Accepted: 02/04/2024] [Indexed: 02/22/2024]
Abstract
Pocket motifs and their amino acid positions of HLA molecules are known to govern antigen presentation to effector cells. Our objective was to analyse their influence on the risk of graft-versus-host disease (GVHD) and relapse after umbilical cord blood transplant (UCBT). The transplant characteristics of 849 patients with acute leukaemia were obtained from the Eurocord/EBMT database. Higher acute (a) GVHD was associated with homozygosity of UCB HLA-C amino acid positions 77 and 80 (NN/KK) (p = 0.008). Severe aGVHD was associated with HLA-A pocket B YSAVMENVHY motif (p = 0.002) and NN and RR genotypes of the HLA-C amino acid positions 77 and 156 (p = 0.006 and p = 0.002). Such risk was also increased in case of recipient and UCB mismatches in P4 (p < 0.0001) and P9 (p = 0.003) pockets of HLA-DQB1 alleles. For chronic GVHD, the pocket B YYAVMEISNY motif of the HLA-B*15:01 allele and the absence of mismatch between recipient and UCB in the P6 pocket of HLA-DRB1 were associated with a lower risk (p = 0.0007 and p = 0.0004). In relapse, both UCB pocket B YFAVMENVHY belonging to HLA-A*32:01 and recipient pocket B YDSVGENYQY motif of the HLA-C*07:01 allele were associated with higher risk (p = 0.0026 and p = 0.015). We provide clues on HLA-mediated cellular interactions and their role in the development of GVHD and relapse.

Graft-versus-host-disease prophylaxis with ATG or PTCY in patients with lymphoproliferative disorders undergoing reduced intensity conditioning regimen HCT from one antigen mismatched unrelated donor. Bone Marrow Transplant 2024; 59:597-603. [PMID: 38331980 PMCID: PMC11073988 DOI: 10.1038/s41409-024-02225-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 01/13/2024] [Accepted: 01/23/2024] [Indexed: 02/10/2024]
Abstract
Post-transplant cyclophosphamide (PTCY) has been introduced as graft-versus-host disease (GvHD) prophylaxis in mismatched and matched unrelated hematopoietic cell transplant (HCT). However, data comparing outcomes of PTCY or ATG in patients undergoing a 1 antigen mismatched HCT for lymphoproliferative disease are limited. We compared PTCY versus ATG in adult patients with lymphoproliferative disease undergoing a first 9/10 MMUD HCT with a reduced intensity conditioning regimen from 2010 to 2021. Patients receiving PTCY were matched to patients receiving ATG according to: age, disease status at transplant, female to male matching, stem cell source and CMV serology. Grade II-IV acute GvHD at 100 day was 26% and 41% for the ATG and PTCY group, respectively (p = 0.08). Grade III-IV acute GvHD was not significantly different between the two groups. No differences were observed in relapse incidence, non-relapse mortality, progression-free survival, overall survival and GvHD-relapse-free survival at 1 year. The cumulative incidence of 1-year extensive chronic GvHD was 18% in the ATG and 5% in the PTCY group, respectively (p = 0.06). In patients with lymphoproliferative diseases undergoing 9/10 MMUD HCT, PTCY might be a safe option providing similar results to ATG prophylaxis. Due to the limited number of patients, prospective randomized trials are needed.

The Benefits of the Post-Transplant Cyclophosphamide in Both Haploidentical and Mismatched Unrelated Donor Setting in Allogeneic Stem Cells Transplantation. Int J Mol Sci 2023; 24:ijms24065764. [PMID: 36982839 PMCID: PMC10051342 DOI: 10.3390/ijms24065764] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 03/03/2023] [Accepted: 03/14/2023] [Indexed: 03/30/2023] Open
Abstract
Allogeneic hematopoietic cell transplantation (alloHSCT) is a standard therapeutic approach for acute leukemias and many other hematologic malignancies. The proper choice of immunosuppressants applicable to different types of transplantations still requires strict and careful consideration, and data in this regard are divergent. For this reason, in this single-centered, retrospective study, we aimed to compare the outcome of 145 patients who received post-transplant cyclophosphamide (PTCy) for MMUD and haplo-HSCT or GvHD prophylaxis for MMUD-HSCT alone. We attempted to verify if PTCy is an optimal strategy in MMUD setting. Ninety-three recipients (93/145; 64.1%) underwent haplo-HSCT while 52 (52/145; 35.9%) underwent MMUD-HSCT. There were 110 patients who received PTCy (93 in haplo and 17 in MMUD group) and 35 patients received conventional GvHD prophylaxis based on antithymocyte globulin (ATG), cyclosporine (CsA), and methotrexate (Mtx) in the MMUD group only. Our study revealed that patients receiving post-transplant cyclophosphamide (PTCy) show decreased acute GvHD rates and CMV reactivation as well as a statistically lower number of CMV copies before and after antiviral treatment compared to the CsA + Mtx + ATG group. Taking into account chronic GvHD, the main predictors are donor age, ≥40 years, and haplo-HSCT administration. Furthermore, the survival rate of patients following MMUD-HSCT and receiving PTCy with tacrolimus and mycophenolate mofetil was more than eight times greater in comparison to patients receiving CsA + Mtx + ATG (OR = 8.31, p = 0.003). These data taken together suggest that the use of PTCy displays more benefits in terms of survival rate compared to ATG regardless of the type of transplantation performed. Nevertheless, more studies with a larger sample size are required to confirm the conflicting results in the literature studies.

Abstract
Thalassaemia is a genetic disorder that affects haemoglobin function. It is an abnormality of haemoglobin caused by mutation of genes related to alpha or beta globin chains that can be further subdivided into categories. These haematological conditions can vary from mild forms, which present as mild anaemia, to severe forms, that can become life-threatening. The window for dental treatment is often limited by several factors involving medical management, such as the need for antibiotic cover or blood transfusions. The lifetime management of the medical conditions are onerous and can place significant physical and psychological burden on the patient. This paper is part of a two-part series on thalassaemia. Part one focuses on the clinical manifestations patients may present with, treatment regimens and dental implications of such presentations. Part two explores the perspectives of thalassaemia patients on their dental experience.

Abstract
Objective: To explore the method of eliminating donor-specific anti-HLA antibodies (DSA)
in haploidentical stem cell transplantation (haplo-SCT). Methods: We present a refractory B-cell acute lymphoblastic leukemia (ALL) patient who
had strongly positive DSA, but had no human leukocyte antigen–matched donor.
Although CD38 expression on leukemia cells was negative, daratumumab
combined with etoposide and venetoclax therapy was chosen for her. Results: She achieved a significant decrease in DSA levels and complete remission on
the combination therapy with daratumumab. She then received a haplo-SCT from
a daughter as a donor and had a successful engraftment of donor stem cell.
In haplo-SCT, strongly positive DSA levels, directed against donor HLA
antigens, could be significantly reduced by daratumumab therapy before
transplantation and successfully bridge subsequent haplo-SCT. Conclusion: Although CD38 expression is negative in leukemia cells, refractory B-ALL
patients may still benefit from combination therapy with daratumumab. We
need further clinical observation.

Abstract
Allogeneic hematopoietic stem cell transplantation (aHSCT) is a lifesaving therapy for hematological malignancies. For years, a fully matched HLA donor was a requisite for the procedure. However, new immunosuppressive strategies have enabled the recruitment of viable alternative donors, particularly haploidentical donors. Over 95% of patients have at least two potential haploidentical donors available to them. To identify the best haploidentical donor, the assessment of new immunogenetic criteria could help. To this end, the clinical benefit of KIR genotyping in aHSCT has been widely studied but remains contentious. This review aims to evaluate the importance of KIR-driven NK cell alloreactivity in the context of aHSCT and explain potential reasons for the discrepancies in the literature. Here, through a non-systematic review, we highlight how the studies in this field and their respective predictive models or scoring strategies could be conceptually opposed, explaining why the role of NK cells remains unclear in aHCST outcomes. We evaluate the limitations of each published prediction model and describe how every scoring strategy to date only partly delivers the requirements for optimally effective NK cells in aHSCT. Finally, we propose approaches toward finding the optimal use of KIR genotyping in aHSCT for a unified criterion for donor selection.

Abstract
BACKGROUND The side effects of conditioning regimens on the success rate of allogeneic transplantation around the world have been challenging. In this study, we aimed to investigate the side effect of Bu/Cy and Bu/Flu regimens on our patients who underwent allogeneic bone marrow transplantation. METHODS We analyzed 180 patients receiving bone marrow transplantation in Taleghani Hospital, in Tehran, Iran between April 2016 and December 2019. Patients in group A received a combination of intravenous busulfan 0.8 mg/kg QID over two hours for 4 consecutive days (12.8 mg/kg in total)(Savani et al., 2006) and cyclophosphamide 60 mg/kg per day for two consecutive days. Patients in group B received busulfan the same as the first group in combination with fludarabine equal to 40 mg/m² per day. Patients were followed up at regular intervals up to two years after transplantation. RESULT Various items were evaluated for patients, including cardiopulmonary function, psychological disorders, GVHD, and endocrine disorders such as hypothyroidism, fertility, or gonad dysfunction. Primary hypothyroidism developed in 13.3% and 11.1% of the Bu/Cy and Bu/Flu groups, respectively (p=0.230). None of the patients in either group experienced infertility or gonad dysfunction. In group A versus group B, pulmonary diseases were detected in 4.4% versus 6.6% of BMT recipients, respectively (p = 0.223). In both groups, mitral and tricuspid regurgitation were observed in patients (8.9% vs. 11.1%; p = 0.189). Incidence of Psychological disorders was no significant difference between the two groups. 32.2% of group A versus 34.45% of group B had skin and liver GVHD, respectively (p = 0.235). CONCLUSION The therapeutic-related adverse effects of the two conditioning regimens in patients who underwent allogeneic bone marrow transplant were almost similar. To improve quality of life and overall survival among BMT patients, careful evaluation of treatment-related complications should be part of the regular follow-up of them.

Abstract
INTRODUCTION Hematopoietic Stem Cell Transplantation (HSCT) is a life-saving procedure for multiple types of hematological cancer, autoimmune diseases, and genetic-linked metabolic diseases in humans. Recipients of HSCT transplant are at high risk of microbial infections that significantly correlate with the presence of graft-versus-host disease (GVHD) and the degree of immunosuppression. Infection in HSCT patients is a leading cause of life-threatening complications and mortality. AREAS COVERED This review covers issues pertinent to infection in the HSCT patient, including bacterial and viral infection; strategies to reduce GVHD; infection patterns; resistance and treatment options; adverse drug reactions to antimicrobials, problems of antimicrobial resistance; perturbation of the microbiome; the role of prebiotics, probiotics, and antimicrobial peptides. We highlight potential strategies to minimize the use of antimicrobials. EXPERT OPINION Measures to control infection and its transmission remain significant HSCT management policy and planning issues. Transplant centers need to consider carefully prophylactic use of antimicrobials for neutropenic patients. The judicious use of appropriate antimicrobials remains a crucial part of the treatment protocol. However, antimicrobials' adverse effects cause microbiome diversity and dysbiosis and have been shown to increase morbidity and mortality.

Abstract
The Human Leukocyte Antigen (HLA) system has a critical role in immunorecognition, transplantation, and disease association. Early typing techniques provided the foundation for genotyping methods that revealed HLA as one of the most complex, polymorphic regions of the human genome. Next Generation Sequencing (NGS), the latest molecular technology introduced in clinical tissue typing laboratories, has demonstrated advantages over other established methods. NGS offers high-resolution sequencing of entire genes in time frames and price points considered unthinkable just a few years ago, contributing a wealth of data informing histocompatibility assessment and standards of clinical care. Although the NGS platforms share a high-throughput massively parallel processing model, differing chemistries provide specific strengths and weaknesses. Research-oriented Third Generation Sequencing and related advances in bioengineering continue to broaden the future of NGS in clinical settings. These diverse applications have demanded equally innovative strategies for data management and computational bioinformatics to support and analyze the unprecedented volume and complexity of data generated by NGS. We discuss some of the challenges and opportunities associated with NGS technologies, providing a comprehensive picture of the historical developments that paved the way for the NGS revolution, its current state and future possibilities for HLA typing.

Efficiency and Toxicity of Ruxolitinib as the Salvage Treatment in Steroid-Refractory Acute Graft-Versus-Host Disease after Haplo-Identical Stem Cell Transplantation. Transplant Cell Ther 2021; 27:332.e1-332.e8. [PMID: 33836880 DOI: 10.1016/j.jtct.2021.01.019] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2020] [Revised: 12/23/2020] [Accepted: 01/21/2021] [Indexed: 12/24/2022]
Abstract
Haplo-identical stem cell transplantation (haplo-SCT) for hematological malignancies has ushered in a new era in which everyone has a potential donor. However, the occurrence of steroid-refractory acute graft-versus-host disease (SR-aGVHD), with no priority among second-line therapies, leads to late mortality after haplo-SCT. Ruxolitinib is the first drug recommended for SR-aGVHD. Here, we report the outcome data from 40 patients after haplo-SCT following the Beijing Protocol who had received ruxolitinib as a salvage therapy for grades II to IV SR-aGVHD in our center between November 2017 and May 2019. The overall response rate was 85% (34/40; 95% confidence interval [CI], 73.4% to 96.6%), including 25 patients with complete response. The median time to first response was 10 days. The levels of inflammatory cytokines and T cell activation declined, and the percentage of regulatory T cells increased. The rate of GVHD relapse was 26.5% (9/34; 95% CI, 10.8% to 42.1%) in responders. Cytomegalovirus reactivation and cytopenia were the major adverse events after ruxolitinib was begun (57.5% and 60%, respectively). The 6-month overall survival estimate was 56.8% (95% CI, 41.5% to 72.1%), and the event-free survival was 45% (95% CI, 29.7% to 60.3%). Liver GVHD was associated with a worse response rate and poor survival. Collectively, ruxolitinib could be an effective treatment for SR-aGVHD patients after haplo-SCT.

Abstract
Graft-versus-host disease (GVHD) prophylaxis based on post-transplant cyclophosphamide (PTCy) or antithymocyte globulin (ATG) is widely used in allogeneic hematopoietic stem cell transplantations (allo-HCT). The differential impacts of PTCy and ATG on transplantation outcomes are not well characterized. Here we report a meta-analysis of PTCy versus ATG in allo-HCT. Ten studies were eligible, and a total of 1871 patients were included. The incidence of II-IV aGVHD, III-IV aGVHD, and NRM were significantly lower in PTCy arm (HR = 0.63, 95% CI 0.45-0.89; HR = 0.35, 95% CI 0.16-0.77; HR = 0.59, 95% CI 0.48-0.73). PTCy was associated with a better OS and PFS (HR = 0.62, 95% CI = 0.53-0.73; HR = 0.76, 95% CI 0.62-0.93). The relapse rate and cGVHD incidence were not significantly different between PTCy and ATG (HR = 0.85, 95% CI 0.68-1.07; HR = 0.65, 95% CI 0.38-1.12). Thus, compared with ATG, PTCy has a better aGVHD control and OS benefit, without increasing relapse risk, which needs further validation in prospective randomized trials.

Abstract
Allogeneic hematopoietic cell transplant (HCT) is a curative therapy for malignant and non-malignant blood diseases. Drug use may be associated with adverse outcomes. We performed a retrospective analysis to assess non-relapse mortality (NRM) and overall survival (OS) in HCT patients with drug use. The medical charts of 232 patients were reviewed. Recipients of matched unrelated donor (MUD) or matched related donor (MRD) transplants were included. Drug use was defined by either metabolic evidence or provider documentation prior to transplant. Transplants were MUD (n = 148) or MRD (n = 84). Median follow-up duration was 15.5 months. There were 35 (15%) patients in the drug use group and 197 (85%) patients in the control group; 49% and 60.4% were in remission at the time of transplant, respectively. In univariate analysis, drug use was associated with a 3-year cumulative incidence of NRM of 43% vs 29% for the control group (p = 0.048), and an HR of 1.75, (95% CI: 1.02-2.99). After controlling for age, sex, disease status, and graft type, drug use was associated with a hazard ratio (HR) of 1.6 (95% CI: 0.95-2.92) for NRM, and an HR 1.2 (95% CI: 0.74-1.94) for OS. Larger cohorts may be needed to further evaluate this association.

Abstract
A mismatched unrelated (MMUD) donor represents an alternative therapeutic option for patients who need allogeneic hematopoietic cell transplantation (allo-HCT) and do not have a human leukocyte antigen (HLA) matched donor. We studied outcomes of patients with acute leukemia transplanted from ≥2 HLA allele MMUD. The study population consisted of 465 patients. The median follow-up period was 63 and 75 months in the AML and ALL groups, respectively. The incidence of grade II-IV and grade III-IV acute (a) graft-versus-host disease (GVHD) during the first 100 days was 37% and 16%, respectively. Total and extensive chronic (c) GVHD rates at 2 years were 38% and 17%, respectively. In the entire population, the 5-year relapse incidence (RI), non-relapse mortality (NRM), leukemia-free survival (LFS), overall survival and refined GVHD-free, relapse-free survival (GRFS) was 33%, 31%, 37%, 41%, and 27%, respectively. In the multivariate analysis, HLA-DR mismatch was a poor prognostic factor, giving a significantly higher NRM [hazard ratio (HR), 1.67, p = 0.02]; poorer LFS (HR, 1.42, p = 0.03); OS (HR, 1.46, p = 0.03) and higher aGVHD grade II-IV (HR, 1.46, p = 0.05). In this study, allo-HCT from ≤6/8 HLA allele MMUD in acute leukemia patients resulted in acceptable LFS and refined GRFS. HLA-DR mismatch was a poor prognostic factor.

Impact of blood pressure early after allogeneic hematopoietic cell transplantation on clinical outcomes. Ann Hematol 2020; 99:1369-1376.

Abstract
Allogeneic hematopoietic transplantation (allo-HCT) is still associated with significant morbidity and mortality, and risk stratification is critical. In this study, we analyzed the relationship between blood pressure control early after allo-HCT and survival outcomes. All patients who survived longer than 28 days after allo-HCT at our center between June 2007 and June 2018 (n = 353) were included, and the average systolic blood pressure (asBP) from 1 to 28 days after allo-HCT was calculated. According to the results of a ROC curve analysis, an asBP of 131 mmHg was defined as a cut-off value between high and low asBP groups. Non-relapse mortality (NRM) and OS were significantly inferior in the high asBP group (2-year-NRM 28.0% vs 11.1%, P < 0.001; 2-year-OS 46.7% vs 65.7%, P = 0.001). In addition, baseline asBP before commencement of the conditioning regimen and elevation of asBP (asBP - baseline asBP) were both associated with inferior NRM. While these results were also observed in the younger patients (≤ 50 years), no relationship was observed in the older patients (> 50 years). High blood pressure within 28 days after allo-HCT was associated with inferior survival outcomes, especially in patients younger than 50 years.

Posttransplant cyclophosphamide vs antithymocyte globulin in HLA-mismatched unrelated donor transplantation. Blood 2019; 134:892-899.

Abstract
Abstract
The use of anti-thymocyte globulin (ATG) has represented the standard of care in graft-versus-host disease (GVHD) prophylaxis in patients undergoing a mismatched unrelated donor (MMUD) transplant. The safety and feasibility of posttransplant cyclophosphamide (PTCY) in this setting have been reported recently, but no study has compared the outcomes of PTCY vs ATG in 9/10 MMUD transplants. Using the registry data of the Acute Leukemia Working Party of the European Society for Blood and Marrow Transplantation, we performed a matched-pair analysis comparing those 2 strategies in a 9/10 MMUD setting. Ninety-three patients receiving PTCY were matched with 179 patients receiving ATG. A significantly lower incidence of severe acute GVHD was observed with PTCY compared with ATG. Recipients of the former also showed higher leukemia-free survival and GVHD/relapse-free survival (GRFS). When performing a subgroup analysis including patients receiving peripheral blood stem cells, being in complete remission, or receiving the same associated immunosuppressive agents, superiority of PTCY over ATG was confirmed. Similar to the haploidentical setting, use of PTCY is an effective anti-GVHD prophylaxis in the 9/10 MMUD transplant. Use of PTCY may also provide better outcomes in long-term disease control. These results need confirmation in large prospective randomized trials.
