Abstract
The COVID-19 pandemic has had a significant impact on medical practices, including the delivery of allogeneic hematopoietic cell transplantation (HCT). In response, transplant centers have made changes to their procedures, including an increased use of cryopreservation for allogeneic haematopoietic progenitor cell (HPC) grafts. The use of cryopreserved grafts for allogeneic HCT has been reviewed and analysed in terms of potential benefits and drawbacks based on existing data on impact on cell subsets, hematological recovery, and clinical outcomes of approximately 2000 patients from different studies. A survey of European Society for Blood and Marrow Transplantation centers was also conducted to assess changes in practice during the pandemic and any unnecessary burdens on HPC donors. Before the pandemic, only 7.4% of transplant centers were routinely cryopreserving HPC products, but this percentage increased to 90% during the pandemic. The results of this review and survey suggest that cryopreservation of HPC grafts is a viable option for allogeneic HCT in certain situations, but further research is needed to determine long-term effects and ethical discussions are required to balance the needs of donors and patients when using frozen allografts.

Cryopreservation of Growth Factor-Mobilized Peripheral Blood Stem Cells Does Not Compromise Major Outcomes after Allogeneic Hematopoietic Cell Transplantation: A Single-Center Experience. Transplant Cell Ther 2023; 29:700.e1-700.e8.

Abstract
During the Coronavirus disease 2019 pandemic, cryopreservation of allogeneic donor stem cell products ensured the availability of products at the start of conditioning for hematopoietic cell transplantation (HCT). Following recommendations from unrelated donor registries, including the National Marrow Donor Program, many centers began to cryopreserve related donor peripheral blood stem cell (PBSC) products. Throughout this process, several centers have published outcomes with cryopreserved versus fresh products, some with conflicting results. Even though cryopreservation was initially considered only a temporary measure driven by the pandemic, potential advantages include greater flexibility of transplantation timing. However, concerns about detrimental effects of cryopreservation, including increased risk of graft rejection, relapse, and consequent mortality, remained. The primary objective of the present study was to describe our center's experience comparing outcomes following PBSC transplantation with cryopreserved versus fresh grafts. This was an observational case study with a retrospective review comparing cryopreserved grafts (n = 213) to a recent historical cohort (controls) using fresh grafts (n = 167). In multivariable analyses, the adjusted hazard ratio (HR) for fresh versus cryopreserved grafts was 1.20 (95% confidence interval [CI], .79 to 1.82; P = .40) for overall mortality, .99 (95% CI, .55 to 1.77; P = .98) for nonrelapse mortality, and .94 (95% CI, .60 to 1.48; P = .80) for relapse. The adjusted HR for platelet engraftment was 1.31 (95% CI, 1.05 to 1.63; P = .02) and the odds ratio of grade III-IV acute GVHD was 1.75 (95% CI, 1.01 to 3.04; P = .05) with fresh grafts compared to cryopreserved grafts. There was no demonstrable difference in the risk of chronic GHVD. Although longer-term follow-up is needed, these data provide preliminary reassurance that in the event of another pandemic or should the logistical need arise in individual patients, cryopreservation of PBSC products is a reasonably safe alternative.

Abstract
At the onset of the COVID-19 pandemic, the National Marrow Donor Program mandated the cryopreservation of hematopoietic cell grafts from volunteer unrelated donors because of numerous patient and donor safety concerns and logistical hurdles. Using the Center for International Blood and Marrow Transplant Research outcomes database, we report the impact of cryopreservation on overall survival (OS) and other outcomes within 1 year after hematopoietic cell transplantation (HCT). We analyzed 1543 recipients of cryopreserved allografts receiving HCT at US centers during the first 6 months of the pandemic and compared them with 2499 recipients of fresh allografts during a 6-month period in 2019. On multivariable regression analysis, we observed no difference in the OS (P = .09), nonrelapse mortality (P = .89), graft-versus-host disease (GVHD), or GVHD- and relapse-free survival (P = .58) in recipients of cryopreserved vs fresh allografts. Disease-free survival (DFS) was lower in the cryopreserved allograft recipients (P = .006) because of a higher risk of relapse (P = .01) compared with the fresh allograft recipients. Primary graft failure was higher (P = .01), and the risk of chronic GVHD was lower (P = .001) with cryopreservation compared with fresh grafts. In conclusion, although there was no negative impact of cryopreservation on OS, relapse was higher, and DFS was lower than that with no cryopreservation. Fresh grafts are recommended as the pandemic-related logistical hurdles resolve. Cryopreservation should be considered an option for patients when fresh grafts are not feasible.

Abstract
INTRODUCTION Due to the expansion of cell therapy using not only haematopoietic stem cells (HSC) but also other leukocyte subpopulations, the loss of these cells in cryopreserved apheresis products needs to be evaluated. Various factors that could negatively affect post-thaw recovery, such as leukapheresis product characteristics, storage time and cryopreservation protocols have been identified. METHODS The post-thaw recovery of HSCs, lymphocytes, NK cells and monocytes, as well as the factors that could adversely affect it were analysed in autologous and allogeneic leukapheresis products. RESULTS The lowest post-thaw recovery was observed in autologous and allogeneic CD34+ cells, with the median of 73.7% and 68.1%, respectively. In leukocyte subpopulation, the lowest post-thaw recovery was observed for CD14+ cells, both autologous and allogeneic. The highest post-thaw recovery was observed for CD3+/CD8+ cells in autologous, and for CD19+ cells in allogeneic samples. The statistically significant difference was observed between autologous and allogeneic PBSC products for CD3+ cell recovery (P = 0.031) and CD3+/CD8+ cell recovery (P = 0.009). The evaluation of factors that could adversely affect the post-thaw recovery in autologous samples showed weak negative correlations between platelet concentration and CD3+ recovery, as well as between storage time and CD3+CD8+ recovery. In allogeneic samples, a strong negative correlation was observed only between the percentage of granulocytes and CD3+, CD3+/CD8+ and CD3+/CD4+ cell recoveries. CONCLUSION Since various post-thaw recoveries of leukocyte subpopulations were observed, the cell therapy manufacturing centers should evaluate how their cryopreservation method and other factors affect the recovery of cell population of interest in their settings.

[PMID: 37271343 PMCID: PMC10234836 DOI: 10.1016/j.jtct.2023.05.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 05/25/2023] [Accepted: 05/26/2023] [Indexed: 06/06/2023]
Abstract
BACKGROUND The SARS-CoV-2 pandemic has deeply impacted hematopoietic stem cell (HSC) donations and transplants. Many changes in practice have been introduced and it is vital to monitor the impact of these on donations and transplants. As part of a global response to this pandemic, the World Marrow Donor Association (WMDA) asked that its member registries and cord blood banks submit SARS-CoV-2-related adverse events to the WMDA-operated Serious Product Events and Adverse Reactions (SPEAR) database. OBJECTIVE This article reviews SARS-CoV-2-related SPEARs that occurred in 2020. STUDY DESIGN The WMDA Serious Product Events and Adverse Reactions (SPEAR) Committee reviewed reports submitted via an online tool. The Committee reviewed each report following the EU definitions of a serious adverse event or reaction and determined the imputability and its impact. Reports submitted in 2020 were included in this analysis RESULTS: 74 such reports were received and were classified as: donor-related 41 (55.4%); recipient-related 3 (4.1%); technical issues 31 (41.8%) transport-related issues 4 (5.4%). Five cases appeared in more than one category. The commonest adverse events reported were of cells being unused. Many of these cases were caused by the uncoupling of the donation and transplant consequent on the cryopreservation of products as well as technical issues related to cell viability. Experience in some registries suggests these issues have become less frequent as transplant centres have become used to the changes in practice. CONCLUSION Lessons learnt include the importance of confirming recipient eligibility before the donors starts mobilisation or collection and minimising the time from collection of cells to transplant. Transplant centres should familiarise themselves with the expected cell losses when PBSC and BM products are cryopreserved and have validated viability assays for quality assurance. Reassuringly there were no reports of donors becoming severely unwell because of G-CSF or of transmission of SARS-CoV-2 to recipients and only one report of complete failure of transport of a donation.

Abstract
BACKGROUND The success of allogeneic hematopoietic stem cell transplantation is dependent on a world-wide network of collection centers providing donations that predominantly have been infused as fresh cells. The logistics chain that supports the just-in-time delivery model for stem cell and immunotherapy products was severely stressed by the COVID pandemic, and in early 2020 a number of national and international bodies recommended that cells should be cryopreserved at the collection or transplant center to avoid interruptions in their acquisition or delivery to patients who had started conditioning. STUDY DESIGN To assess the potential consequences of such pandemic-related deviations to normal practice, we surveyed nine international laboratories to determine if the characteristics or transplant outcomes of allogeneic stem cell donations differed in the immediate periods before and after the switch to routine cryopreservation. RESULTS Nine centers on two continents provided data for 72 HSC donations just before, and 71 just after, switching to cryopreservation for allogeneic HSC products. No statistically significant differences between the period before and after cryopreservation were noted for time from product collection to receipt, product temperature at receipt, or CD34+ cell viability at receipt. There was an indication of slower absolute neutrophil count recovery after cryopreservation was required (mean time of 15 vs. 17.6 days). DISCUSSION While there were no apparent changes to most parameters studied, there was an indication of slower neutrophil engraftment that will need to be examined in larger, longer term studies.

Abstract
Despite the readily available graft sources for allogeneic hematopoietic cell transplantation (alloHCT), a significant unmet need remains in the timely provision of suitable unrelated donor grafts. This shortage is related to the rarity of certain HLA alleles in the donor pool, nonclearance of donors owing to infectious disease or general health status, and prolonged graft procurement and processing times. An alternative hematopoietic progenitor cell (HPC) graft source obtained from the vertebral bodies (VBs) of deceased organ donors could alleviate many of the obstacles associated with using grafts from healthy living donors or umbilical cord blood (UCB). Deceased organ donor-derived bone marrow (BM) can be preemptively screened, cryogenically banked for on-demand use, and made available in adequate cell doses for HCT. We have developed a good manufacturing practice (GMP)-compliant process to recover and cryogenically bank VB-derived HPCs from deceased organ donor (OD) BM. Here we present results from an analysis of HPCs from BM obtained from 250 deceased donors to identify any substantial difference in composition or quality compared with HPCs from BM aspirated from the iliac crests of healthy living donors. BM from deceased donor VBs was processed in a central GMP facility and packaged for cryopreservation in 5% DMSO/2.5% human serum albumin. BM aspirated from living donor iliac crests was obtained and used for comparison. A portion of each specimen was analyzed before and after cryopreservation by flow cytometry and colony-forming unit potential. Bone marrow chimerism potential was assessed in irradiated immunocompromised NSG mice. Analysis of variance with Bonferroni correction for multiple comparisons was used to determine how cryopreservation affects BM cells and to evaluate indicators of successful engraftment of BM cells into irradiated murine models. The t test (with 95% confidence intervals [CIs]) was used to compare cells from deceased donors and living donors. A final dataset of complete clinical and matched laboratory data from 226 cryopreserved samples was used in linear regressions to predict outcomes of BM HPC processing. When compared before and after cryopreservation, OD-derived BM HPCs were found to be stable, with CD34+ cells maintaining high viability and function after thawing. The yield from a single donor is sufficient for transplantation of an average of 1.6 patients (range, 1.2 to 7.5). CD34+ cells from OD-derived HPCs from BM productively engrafted sublethally irradiated immunocompromised mouse BM (>44% and >67% chimerism at 8 and 16 weeks, respectively). Flow cytometry and secondary transplantation confirmed that OD HPCs from BM is composed of long-term engrafting CD34+CD38-CD45RA-CD90+CD49f+ HSCs. Linear regression identified no meaningful predictive associations between selected donor-related characteristics and OD BM HPC quality or yield. Collectively, these data demonstrate that cryopreserved BM HPCs from deceased organ donors is potent and functionally equivalent to living donor BM HPCs and is a viable on-demand graft source for clinical HCT. Prospective clinical trials will soon commence in collaboration with the Center for International Blood and Marrow Research to assess the feasibility, safety, and efficacy of Ossium HPCs from BM (ClinicalTrials.gov identifier NCT05068401).

Abstract
The COVID-19 pandemic disorganized the allogeneic stem cell transplantation activities all over the world, with the necessity to cryopreserve allografts to secure the procedure for both the recipient and the donor. Cryopreservation, usually anecdotal, has been used by all the French speaking centers; data collected from 24 centers were assessed in order to determine the impact of cryopreservation on the quality of allografts. Our analysis clearly demonstrates that increasing transit time (more than 48hours) is deleterious for CD34+ recovery, legitimates the slight increase of the requested CD34+ cell dose with respect to the average recovery rate as well as the importance of the quality control on the infused product.

Cryopreserved versus fresh peripheral blood allogeneic stem cell transplantation outcomes in patients receiving post-transplant cyclophosphamide for graft-versus-host prophylaxis during the COVID-19 pandemic: a single center experience. Int J Hematol 2023; 117:428-437. [PMID: 36378406 PMCID: PMC9664429 DOI: 10.1007/s12185-022-03493-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 11/07/2022] [Accepted: 11/07/2022] [Indexed: 11/16/2022]
Abstract
BACKGROUND/OBJECTIVE Cryopreservation of grafts is not common practice in allogeneic hematopoietic stem cell transplant (HSCT) recipients. However, our center had to use cryopreserved cells for allogeneic HSCT during the COVID-19 pandemic to avoid delays in transplantation due to uncertainty regarding patient and donor exposures. STUDY DESIGN We retrospectively evaluated post-transplant engraftment and survival outcomes of adult patients who received cryopreserved versus fresh allografts during the COVID-19 pandemic. RESULTS Fifty-five patients with hematologic malignancies received either cryopreserved (n = 34) or fresh (n = 21) allogeneic HSCT using peripheral blood stem cells between January 2020 and December 2020. At a median follow-up time of 15 months, cryopreserved allograft recipients had significantly lower overall survival (OS) (p = 0.02). They also experienced significantly delayed neutrophil (p = 0.01) and platelet engraftments (p < 0.0001), as well as higher red blood cell transfusion-dependence after day + 60 (67.6% vs. 28.6%; p = 0.01). Significantly more cryopreserved allograft recipients received donor lymphocyte infusion than fresh allograft recipients (35.3% vs. 4.8%, p = 0.01). Neither relapse-free survival nor non-relapse mortality differed significantly between the two groups. CONCLUSION Cryopreservation of allografts in combination with post-transplant cyclophosphamide may negatively affect engraftment and OS outcomes in HSCT recipients.

Abstract
Background Since the beginning of the SARS-CoV-2 pandemic, identifying the COVID-19 pathophysiology not only has been addressed to applying diagnostic tests or preventing through vaccines, but also to the timely detection, especially of patients in risk groups such as those in transplants areas (renal, hematology, etcetera). In the case of these patients, using RT-PCR tests avoids putting them at risk by subjecting them to states of immunosuppression that could aggravate their situation if they were faced with an onset of a COVID-19 infection. Objective To present the results of patients of a transplant unit tested for SARS-CoV-2. Material and methods Descriptive, observational, cross-sectional, and retrolective study. Data of results of RT-PCR tests of patients who underwent transplantation from June 2021 to April 2022 in a third level hospital were collected. Results 755 tests were done to patients who underwent transplantation. 384 (50.8%) were women. Out of all patients, only 73 (9.7%) were positive to SARS-CoV-2. Conclusions Implementing RT-PCR tests as a transplant protocol to detect SARS-CoV-2 prevents fatal complications due to COVID infection to donors and receptors.

Abstract
ZusammenfassungEin breites Spektrum von Disruptionen, aber auch blitzschnelle Innovationen, hat
die SARS-CoV-2 Pandemie gebracht. Dieser Übersichtsartikel betrachtet
die Pandemie aus der Warte der Zelltherapie; konkret werden vier Aspekte
untersucht: Wie unterscheiden sich die Risiken von Zelltherapie-Patienten mit
SARS-CoV-2 Infektion und COVID von denen der Allgemeinbevölkerung? Sind
Empfänger von Zelltherapien, hier speziell autologe und allogene
Stammzelltransplantationsempfänger sowie Empfänger von
CAR-T-Zell-Präparaten, klinisch relevant durch SARS-CoV-2 Vakzine
immunisierbar? Welche Auswirkungen hat die Pandemie mit Spenderausfallrisiko und
Zusammenbruch von Supply Chains auf die Versorgung mit Zelltherapeutika? Gibt es
Zelltherapeutika, die bei schwerem COVID therapeutisch nutzbringend eingesetzt
werden können? In aller Kürze, das erwartete massiv
erhöhte Risiko von Zelltherapie-Patienten, im Infektionsfall einen
schweren Verlauf zu erleiden oder zu sterben, wurde bestätigt. Die
Vakzine induziert jedoch bei vielen dieser Patienten humorale und
zelluläre Immunität, wenn auch weniger zuverlässig als
bei Gesunden. Dank kreativer Lösungen gelang es, die Versorgung mit
Zelltherapeutika im Wesentlichen uneingeschränkt aufrecht zu erhalten.
SARS-CoV-2-spezifische T-Zell-Präparate für den adoptiven
Immuntransfer wurden entwickelt, eine therapeutische Konstellation diese
anzuwenden ergab sich jedoch nicht. Therapiestudien mit mesenchymalen
Stromazellen beim schweren COVID laufen weltweit; die Frage der Wirksamkeit
bleibt zurzeit offen, bei jedoch substanziellem Optimismus in der Szene. Einige
der Erkenntnisse und Innovationen aus der SARS-CoV-2-Pandemie können
möglicherweise verallgemeinert werden und so auf die Zeit nach ihrem
Ende langfristig nachwirken.

Abstract
Cryopreservation was recommended to ensure continuity in allogeneic hematopoietic progenitor cells (HPC) transplantation during the COVID-19 pandemic. Several groups have shown no impact on clinical outcomes for patients who underwent HPC transplantation with cryopreserved products during the first months of this pandemic. However, concerns about quality control attributes after cryopreservation have been raised. We investigated, in 155 allogeneic peripheral blood cryopreserved HPC, leukocytapheresis characteristics influencing viable CD34+ and CD3+ cells, and CFU-GM recoveries after thawing. Collection characteristics such as volume, nucleated cells (NC)/mL and hematocrit correlated with viable CD34+ and CD3+ cells recoveries after thawing in univariate analysis but only CD3+ cells remained statistically significant in multivariate analysis (r2 = 0.376; P = < 0.001). Additionally, transit time also showed correlation with viable CD34+ (r2 = 0.186), CD3+ (r2 = 0.376) and CFU-GM recoveries (r2 = 0.212) in multivariate analysis. Thus, diluting leukocytapheresis below 200 × 106 NC/mL, avoiding red cells contamination above 2%, cryopreserving below 250 × 106 NC/mL and minimizing transit time below 36 h, prevented poor viable CD34+ and CD3+ cells, and CFU-GM recoveries. In summary, optimizing leukocytapheresis practices and minimizing transportation time may better preserve the quality attributes of HPC when cryopreservation is indicated.

Real-world Experience of Cryopreserved Allogeneic Hematopoietic Grafts in the COVID-19 Pandemic: A Single Center Report. Transplant Cell Ther 2022; 28:215.e1-215.e10.

Abstract
In response to the widespread COVID-19 pandemic, cryopreservation of allogeneic donor apheresis products was implemented to mitigate the challenges of donor availability and product transport. Although logistically beneficial, the impact of cryopreservation on clinical outcomes and graft composition remains unclear. In this study, we compared outcomes and graft composition with cryopreserved versus fresh allografts in the setting of allogeneic hematopoietic cell transplantation (allo-HCT). We retrospectively analyzed the clinical outcomes of 30 consecutive patients who received cryopreserved allografts between March and August 2020 and 60 consecutive patients who received fresh allografts before the COVID-19 pandemic. Primary endpoints were hematopoietic engraftment and graft failure (GF), and secondary outcomes were overall survival (OS), relapse-free survival (RFS) and nonrelapse mortality (NRM). In addition, extended immunophenotype analysis was performed on cryopreserved and prospectively collected fresh apheresis samples. Compared with recipients of fresh allografts, both neutrophil and platelet recovery were delayed in recipients of cryopreserved reduced-intensity conditioning (RIC) allo-HCT, with a median time to engraftment of 24 days versus 18 days (P = .01) for neutrophils and 27 days versus 18 days (P = .069) for platelets. We observed primary GF in 4 of 30 patients in the cryopreserved cohort (13.3%) versus only 1 of 60 patients (1.7 %) in the fresh cohort (P = .03). Cryopreserved RIC allo-HCT was associated with significantly lower median total, myeloid, and T cell donor chimerism at 1 month. OS and RFS were inferior for cryopreserved graft recipients (hazard ratio [HR], 2.16; 95% confidence interval [CI], 1.00 to 4.67) and HR, 1.90; 95% CI, 0.95 to 3.79, respectively. Using an extended immunophenotype analysis, we compared 14 samples from the cryopreserved cohort to 6 prospectively collected fresh apheresis donor samples. These analyses showed both a decrease in total cell viability and a significantly reduced absolute number of natural killer cells (CD3−CD56+) in the cryopreserved apheresis samples. In this single-institution study, we found delayed engraftment and a trend toward clinical inferiority of cryopreserved allografts compared with fresh allografts. Further evaluation of the use of cryopreserved allografts and their impact on clinical and laboratory outcomes is warranted.

Abstract
PURPOSE OF REVIEW Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) impacted every facet of hematopoietic cell transplantation. This article reviews the adjustments to recipient and donor care that occurred in response to this unprecedented event. RECENT FINDINGS Transplant centers modified algorithms, patient flow, education, and how we provided care. Our donor center partners reworked how donors were evaluated and products delivered to the transplant center. Our professional societies provided guidelines for patient and donor care and rapidly modified these based upon the never-ending stream of new data learned about SARS-CoV-2. Our research organizations provided rapid analyses to ensure the care modifications necessitated did not have a profound negative impact on our patients or donors. SUMMARY The efforts of transplant providers and donor centers worldwide allowed patients to receive the transplant needed with assurances that they were receiving the best care available despite the worldwide challenge.

Abstract
Changes to donor availability, collection center capacity, and travel restrictions during the early phase of the COVID-19 pandemic led to routine cryopreservation of most unrelated donor products for hematopoietic transplantation prior to the recipient commencing the conditioning regimen. We investigated the effect of this change on unrelated donor product quality and clinical outcomes. Product information was requested from transplantation centers in Australia and New Zealand and clinical outcome data from the Australasian Bone Marrow Transplant Recipient Registry (ABMTRR). In total, 191 products were collected between April 1, 2021, and September 30, 2021, and most (74%) were from international collection centers. Median post-thaw CD34 recovery was 78% (range 25% to 176%) and median post-thaw CD34 viability was 87% (range 34% to 112%). Median time to neutrophil recovery was 17 days (interquartile range 10 to 24 days), and graft failure occurred in 6 patients (4%). These clinical outcomes were similar to those of "fresh" unrelated donor transplants reported to the ABMTRR in 2019. However, recipient transplantation centers reported problems with 29% of products in the form of damage during transit, low cell dose, inadequate labeling, missing representative samples, or missing documentation. These problems were critical in 7 cases (4%). At last follow-up, 22 products (12%) had not been infused. Routine cryopreservation of unrelated donor hemopoietic progenitor cell products has enabled safe continuation of allogeneic transplant services during the COVID-19 pandemic. However, practices for product tracing, documentation, and transportation can be optimized, and measures to reduce the incidence of unused unrelated donor product are required.
