Investigating the effect of pre-transplant thrombocytopenia and anemia on the engraftment and long-term survival in multiple myeloma patients. Transpl Immunol 2024; 82:101991. [PMID: 38199269 DOI: 10.1016/j.trim.2024.101991] [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: 05/14/2023] [Revised: 12/29/2023] [Accepted: 01/07/2024] [Indexed: 01/12/2024]
Abstract
BACKGROUND Autologous stem cell transplantation (ASCT) following high-dose melphalan is the standard treatment for Multiple Myeloma (MM). Despite new treatments, further investigation is needed to identify prognostic factors of ASCT. This study evaluated the impact of thrombocytopenia and anemia on the engraftment of MM patients after ASCT. MATERIALS AND METHODS This retrospective study involved 123 MM patients who underwent ASCT with high-dose Melphalan. Successful engraftment is achieved when both platelets (Plt) and white blood cells (WBC) engraft successfully. We examined the statistically significant cut-offs for the prognostic factors on the admission day. Ultimately, the association of risk factors with the Plt and WBC engraftment and long-term survival were analyzed as the outcomes of interest. RESULTS Spearman's correlation coefficient between Plt and WBC engraftment was 0.396 (p < 0.001). The engraftment in the patients with Plt < 140,000/μL was 17.4% slower (p = 0.036) and the odds of long-term survival was 72% lower (p = 0.016) than in patients with higher Plt. Patients with Hb < 11 g/dL were 12.7% slower in engraftment. Age over 47 was a significant factor in slower engraftment (p = 0.036) which decelerated the engraftment by 15.2%. CONCLUSION Thrombocytopenia and anemia before transplantation are related to slower Plt/WBC engraftment and as prognostic factors might predict the long-term survival of MM patients following ASCT.

Lack of RBC transfusion independence by Day 30 following allogeneic hematopoietic stem cell transplant strongly predicts inferior survival and high non-relapse mortality in acute myeloid leukemia patients. Transfusion 2024; 64:255-280. [PMID: 38225215 DOI: 10.1111/trf.17714] [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: 08/15/2023] [Revised: 11/29/2023] [Accepted: 12/15/2023] [Indexed: 01/17/2024]
Abstract
BACKGROUND Studies have suggested that acute myeloid leukemia (AML) patients with incomplete hematologic recovery undergoing allogeneic stem cell transplantation (allo-HSCT) had inferior overall survival (OS). STUDY DESIGN AND METHODS This single-center, retrospective study of AML patients evaluated the relationship between red blood cell (RBC) and platelet (PLT) transfusion requirements during the first 30 days and long-term outcomes after allo-HSCT through multivariate analyses. RESULTS A total of 692 AML patients received peripheral blood stem cells (89.2%), marrow (5.6%), or umbilical cord (5.2%) from matched related (37.4%), unrelated (49.1%), or haploidentical (8.2%) donors in 2011-2017. Transfusion requirements during the first 30 days for RBC (89.5% transfused, median 3, range 1-18 units) or PLT (98.2% transfused, median 6, range 1-144 units) were variable. By Day 30, 56.7% (95% confidence interval [CI]: 52.8-60.3%) and 86.1% (95% CI: 83.2-88.5%) had achieved RBC and PLT transfusion independence, respectively. Median follow-up among survivors (n = 307) was 7.1 years (range: 2.7-11.8). Lack of RBC transfusion independence by Day 30 was strongly and independently associated with worse 5-year OS (39.2% vs. 59.6%, adjusted hazard ratio [HR] 1.83, 95% CI: 1.49-2.25), leukemia-free survival (35.8% vs. 55.5%, HR = 1.75, 95% CI: 1.43-2.14), and NRM (29.7% vs. 13.7%, HR = 2.05, 95% CI: 1.45-2.89) (p < .001). There was no difference in relapse rates among patients who achieved or did not achieve RBC (p = .34) or PLT (p = .64) transfusion independence. CONCLUSION Prolonged RBC dependence predicted worse survival and NRM rates, but not increased relapse. Posttransplant surveillance of such patients should be adjusted with more attention to non-relapse complications.

Analysis of the Efficacy and Safety of Avatrombopag Combined With MSCs for the Treatment of Thrombocytopenia After Allogeneic Hematopoietic Stem Cell Transplantation. Front Immunol 2022; 13:910893. [PMID: 35693772 PMCID: PMC9184517 DOI: 10.3389/fimmu.2022.910893] [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: 04/01/2022] [Accepted: 04/29/2022] [Indexed: 01/05/2023] Open
Abstract
Platelet graft failure (PGF) is a frequent and serious complication after Allogeneic hematopoietic stem cell transplantation (allo-HSCT) and lacks effective treatment strategies, which could affect the prognosis of patients and even cause death. The exact underlying mechanism of PGF remains unclear, and lacks standard treatment. Here, we conduct a retrospective study to evaluate the efficacy and safety of avatrombopag combined with mesenchymal stem cells (MSCs) in 16 patients with thrombocytopenia after allo-HSCT. Patients were administered the following treatment regimen: 20 mg/d avatrombopag; if the PLT count was less than 50×10^9/L for at least 2 weeks, the dose was increased to 40 mg/d; if the PLT count was 200-400×10^9/L, the dose was reduced; and if the PLT count was greater than 400×10^9/L, avatrombopag was terminated. Umbilical cord MSCs (1×10^6 cells/kg) infusion was performed every week for 4-6 weeks. Among the 16 patients, 13 patients (81.3%) achieved a complete response (CR), 2 patients (12.5%) got a partial response (PR), and 1 patient (6.3%) had no response (NR). The median time to obtain CR was 32 (7-426) days after treatment with avatrombopag combined with umbilical cord MSCs. The time to reach 20×10^9/L≤ PLT <50×10^9/L in the 2 patients with PR was 52 and 230 days after treatment, respectively. One patient had a severe pulmonary infection and died of cytomegalovirus pneumonia. Overall, our results indicated that combination of avatrombopag with MSCs can promote platelet recovery after transplantation, thereby improving the survival rate of patients and improving the quality of life of patients after transplantation, and providing a new method and strategy for the treatment of thrombocytopenia after allo-HSCT.

Abstract
BACKGROUND Transfusions are essential for allogeneic hematopoietic cell transplant (HCT), yet they are influenced by graft, donor, and other factors. STUDY DESIGN We analyzed transfusions in 165 adult reduced intensity HCTs (2016-2019): HLA matched sibling donor (MSD) (n = 59), matched URD (n = 25), UCB (n = 33), and haploidentical (haplo, n = 48) detailing the cumulative incidence of platelet and RBC transfusion independence, total transfusions (day-10 to day+100) plus transfusion densities (per week) over 110 days. RESULTS Platelet recovery to 20 × 109 /L by 6 months occurred in 39/48 (81.25%) haplo recipients (median 33 [range, 0-139]) days vs. 58/59 (98.3%) MSD (median 10 [0-37]), 21/25 (84%) matched URD (median 20 [0-153]), and 29/33 (87.87%) UCB (median 48 [29-166]) days, p < .01. Regression analysis demonstrated a lower likelihood of prompt platelet recovery in matched URD, UCB, or haplo HCTs vs. MSD. Recovery to platelet independence was quickest in MSD (median 8 days [range 0-94]), vs. URD (median 16 days [0-99]), UCB (median 57 [0-94]), or haplo (median 45 [12-97]) days, p < .01. Platelet needs were unaffected by age, conditioning, or acute GVHD. RBC transfusion independence was achieved in 78% of MSD, 64% URD, and 82% UCB, though less frequent (58%) and slowest in haplo recipients, p < .01. All haplo and UCB recipients required platelet transfusions vs. only 51% of MSD and 76% of URD. RBC needs were highest in UCB and haplo HCTs. DISCUSSION The transplant donor influences the transfusion burden with greater platelet and RBC needs in haplo and UCB HCT which directly contributes to increased cost of care.

Abstract
BACKGROUND Allogeneic hematopoietic stem cell transplant (allo-HSCT) recipients often require substantial but variable transfusion support. STUDY DESIGN AND METHODS This single-center, retrospective study evaluated the red blood cell (RBC) and platelet (PLT) transfusion data of first-time allo-HSCT recipients transplanted in 2011 to 2017. Multivariate analyses were performed to assess the associations between patient and transplant-related factors and transfusion requirements. RESULTS The study included 1762 patients who received peripheral blood stem cells (88.2%), marrow (7.0%), or umbilical cord (4.8%) from matched related (38.3%), unrelated (49.2%), or haploidentical (7.8%) donors. Almost all patients required RBCs (88.3%) or PLTs (97.4%) during the first 30 days, with medians of 3 (range, 1-37) RBC and 6 (range, 1-144) PLT units transfused. Fewer patients required RBC (43.8%) or PLT (27.3%) transfusions during Days 31 to 100, but the median (range) numbers of RBC and PLT units remained high at 3 (1-36) and 6 (1-116) among transfused patients. RBC and PLT transfusion independence was reached in medians of 24 (95% confidence interval [CI], 22-26) and 12 (95% CI, 11-12) days, respectively. Haploidentical donor, cord graft, and requiring RBC transfusions in the 10 days before HSCT were the most significant independent factors predictive of increased transfusion requirements. Advanced disease, diagnosis, ABO incompatibility, conditioning intensity, CD34+ cell dose, presence of severe acute graft-vs-host disease, and changes in recommended transfusion triggers were also shown to independently impact transfusion requirements. CONCLUSIONS This study provided for the first time quantitative and comparative transfusion data on a large contemporary cohort of HSCT recipients, including haploidentical and cord graft recipients, and identified factors predictive of increased transfusions.

Pre-transplant thrombocytopenia predicts engraftment time and blood products requirement in allogeneic hematopoietic stem cell transplantation patients. Transfus Apher Sci 2020; 59:102810. [PMID: 32430259 DOI: 10.1016/j.transci.2020.102810] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2019] [Revised: 03/29/2020] [Accepted: 04/27/2020] [Indexed: 11/25/2022]
Abstract
INTRODUCTION Thrombocytopenia is a common consequence of leukemia that affects the outcome of hematopoietic stem cell transplantation (HSCT). The stromal damage of bone marrow following pre-HSCT conditioning regimens can delay the hematopoietic engraftment and increased blood product transfusions. We tried to define threshold based on pre-transplant platelet count as a biomarker to predict engraftment time and blood product requirements in allogeneic HSCT patients. METHODS This retrospective study was performed on 194 patients who received allogeneic HSCT. The median for platelet (PLT) count of patients at the admission day was considered as a cut off value. The association of platelet count with white blood cell (WBC) and PLT engraftment time and also the requirement of packed red blood cell or PLT transfusions as outcomes of interest were investigated. RESULTS 164 patients (84.5 %) had successful WBC engraftment, and PLT engraftment was seen in 155 patients (79.9 %) in 30 and 50 days after HSCT, respectively. The patients with PLT count higher than 154,000/μL had better PLT engraftment (P = 0.060), and WBC engraftment (P = 0.014) than those with PLT count lower than this cut off. The pre-transplant PLT count had negative relations with SD platelet requests after HSCT (P = 0.008). CONCLUSION The thrombocytopenia before HSCT might delay the platelet and WBC engraftment time, which should be taken into account before transplantation. Since the blood product transfusion is one of the factors associated with engraftment, the pre-transplant platelet count can be used as a predictive biomarker to manage the blood product requirement during the HSCT until engraftment occurs.

Abstract
The optimal intensity of myeloablation associated with a reduced-toxicity conditioning (RTC) regimen in order to decrease the relapse rate without increasing non-relapse mortality (NRM), is not well established yet. This retrospective analysis was done on 30 patients with hematological malignancies. The aim was to assess the safety of a RTC regimen based on the busulfan at a dose of 100 mg/m(2)/d intravenously for 4 d, fludarabine at a dose of 30 mg/m(2)/d for 5 d, and anti-thymoglobulins at a dose of 2.5 mg/kg/d for 2 d. The cumulative incidences of grade 2-4 acute graft-versus-host disease (GVHD) and all grades chronic GVHD were 37% and 42%, respectively. Median 1-year overall survival and disease-free survival were 66% and 50%, respectively. At 1 year, the cumulative incidence of relapse/disease progression was 33%. NRM was 3% and 17% at day 100 and 1 year, respectively. This RTC conditioning regimen can lead to a long-term disease control. Moreover, it appears to be safe with a low NRM rate among high-risk patients.

Abstract
Successful utilization of SCT modalities often requires utilization of both red cell and platelet transfusions. In this retrospective evaluation of clinical factors affecting transplant engraftment and transfusion utilization at a single transplant center in 505 patients from 2005 through 2009, we found that graft type, donor type and the conditioning regimen intensity significantly affected both the neutrophil engraftment time (P<0.001) and the platelet engraftment time (P<0.001). SCT patients required an average of 6.2 red cell units, and 7.9 platelet transfusions in the first 100 days with a wide s.d. Among auto-SCT patients, 5% required neither RBC nor platelet transfusions. Some reduced-intensity transplants were also associated with no transfusion need, and in allogeneic transplants, conditioning regimen intensity was positively correlated with platelet transfusion events as assessed by multivariate analysis. Other patient characteristics such as gender, graft type, donor type, underlying disease and use of TBI were all independently associated with transfusion needs in SCT patients. Further studies are required to understand the means to minimize transfusions and potential related complications in SCT patients.

Abstract
Allogeneic hematopoietic cell transplantation (HCT) recipients have substantial transfusion requirements. Factors associated with increased transfusions and the extent of blood product use in umbilical cord blood (UCB) recipients are uncertain. We reviewed blood product use in 229 consecutive adult recipients of allogeneic HCT at the University of Minnesota: 147 with leukemia, 82 lymphoma or myeloma; 58% received unrelated UCB and 43% sibling donor peripheral blood stem cell (PBSC) grafts. Although neutrophil recovery was prompt (UCB median 17, range: 2-45 days, and PBSC 14, range: 3-34 days), only 135 of 229 (59% cumulative incidence) achieved red blood cell (RBC) independence and 157 (69%) achieved platelet independence by 6 months. Time to platelet independence was prolonged in UCB recipients (median UCB 41 versus PBSC 14 days) and in patients who had received a prior transplant (median 48 versus 32 days). Patients who received UCB grafts required more RBC through day 60 post-HCT (mean UCB 7.8 (95% confidence interval [CI] 6.7-8.9) versus PBSC 5.2 (3.7-6.7) transfusions, P = .04), and more platelet transfusions (mean 25.2 (95% CI 22.1-28.2) versus 12.9 (9.4-16.4), P < .01) compared to PBSC recipients. Patients receiving myeloablative (MA) conditioning required more RBC and platelet transfusions during the first 2 months post-HCT compared to reduced-intensity conditioning (RIC) (7.4 versus 6.2, P = .30 for RBC; 23.2 versus 17.5, P = .07 for platelets). Despite prompt neutrophil engraftment, UCB recipients had delayed platelet recovery as well as more prolonged and costly blood product requirements. Enhanced approaches to accelerate multilineage engraftment could limit the transfusion-associated morbidity and costs accompanying UCB allotransplantation.

Abstract
Delayed platelet recovery (DPR) is common after allo-SCT. Insufficient data on risk factors and association with OS and TRM are available. We conducted a retrospective analysis of all allografts at the University of Minnesota between 2000 and 2005 to characterize the frequency of DPR (platelets <50 000/μL by day 60), risk factors and related complications. A total of 850 patients with hematological malignancies and benign disorders were included. Myeloablative (MA) conditioning was used in 65% of the patients and 45% received umbilical cord blood (UCB) grafts. The 60-day cumulative incidence of platelet recovery was 40% in UCB, 57% in unrelated donor (URD) and 74% in sibling donor. Multivariate analysis confirmed that the variables associated with DPR were MA (versus reduced intensity) conditioning, graft source other than sibling donor, ABO major mismatch, recipient CMV-positive serostatus, the presence of grade II-IV acute GVHD and slower neutrophil recovery. These data demonstrate that DPR is frequent after allogeneic hematopoietic cell transplantation, especially after UCB. DPR is a significant independent risk factor for increased TRM and poorer OS along with HLA-mismatched URD, but not UCB, grade II-IV acute GVHD, old age and advanced disease stage.
