Abstract
The low-dose anti-thymocyte globulin (ATG) plus low-dose post transplantation cyclophosphamide (PTCy) -based (low-dose ATG/PTCy-based) regimen had a promising activity in preventing of graft-versus-host disease (GVHD) in adult patients. However, its efficacy in pediatric patients remain to be defined. Here, we presented the findings from 35 pediatric patients undergoing haploidentical peripheral blood stem cell transplantation (haplo-PBSCT) with the new regimen for GVHD prophylaxis. The cumulative incidences (CIs) of grades II-III and III-IV acute GVHD (aGVHD) were 34% (95% CI, 17-48%) and 11% (95% CI, 0-21%) within 180 days post-transplantation, respectively. The CIs of chronic GVHD (cGVHD) and moderate-to-severe cGVHD within 2 years were 26% (95% CI, 7-41%) and 12% (95% CI, 0-25%), respectively. The 2-year probabilities of overall survival, relapse-free survival, and graft-versus-host disease and relapse-free survival were 89% (95% CI, 78-100%), 82% (95% CI, 68-98%) and 59% (95% CI, 43-80%), respectively. The CIs of cytomegalovirus (CMV) and Epstein-Barr virus (EBV) reactivation by day 180 were 37% (95% CI, 19-51%) and 20% (95% CI, 6-32%) respectively. These results strongly advocate for the efficacy of the low-dose ATG/PTCy-based regimen as a robust strategy for GVHD prevention in haplo-PBSCT for pediatric patients.

Abstract
BACKGROUND Total body irradiation (TBI) for hematopoietic stem cell transplant (HSCT) has certain distinct advantages, such as uniform dose distribution and lack of drug resistance, but it is not widely available in resource-constrained settings. To overcome the limitations of in-house radiotherapy services in hematology centers, we evaluated the feasibility of conducting HSCT programs in coordination with two physically distant centers using a reduced-intensity TBI protocol. METHODS Thirty-two patients with a median age of 20.5 years were included in the study. Fifteen patients were diagnosed with aplastic anemia, 10 patients with acute myeloid leukemia (AML), 3 patients with acute lymphocytic leukemia (ALL), and 4 patients with other hematological conditions. Conditioning regimens used were fludarabine plus cyclophosphamide in 29 cases, fludarabine-cytarabine ATG in 2 cases, and busulfan plus fludarabine in 1 case. The TBI dose was 3 Gy in 28 cases and 2 Gy in 4 cases. Patients were followed monthly after TBI, and the major toxicities were recorded. RESULTS The median follow-up was 22 months. The most common acute complication was acute graft-versus-host disease (GVHD), which occurred in 15.6% of patients. The major late complications were chronic GVHD (9.3%), Cytomegalovirus (CMV) infection (34.3%), and CMV-induced secondary graft failure (6.2%). Seventy-five percent of patients were alive, 21.9% were dead, and 1 patient was lost to follow-up. CONCLUSIONS HSCT based on TBI is feasible even if the center lacks a radiotherapy facility by coordinating with a remote radiotherapy facility. without compromising the patient's outcome.

Incidence and Role of Recipient-Specific Antibodies in Allogeneic Hematopoietic Cell Transplantation from Mismatched Related Donors. Transplant Cell Ther 2024; 30:99.e1-99.e10. [PMID: 37875214 DOI: 10.1016/j.jtct.2023.10.015] [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: 09/01/2023] [Revised: 10/13/2023] [Accepted: 10/20/2023] [Indexed: 10/26/2023]
Abstract
High titer of donor-specific antibodies (DSAs) increases the risk of graft rejection after mismatched related hematopoietic cell transplantation (HCT). There are no data regarding the incidence of anti-HLA recipient-specific antibodies (RSAs) and their role after transplantation. Here we aimed to identify the incidence of RSAs in a mismatched related hematopoietic cell donor population and their possible impact on immune-mediated complications, such as acute graft-versus-host disease (aGVHD), and complications resulting from endothelial injury, such as transplantation-associated thrombotic microangiopathy (TA-TMA) and veno-occlusive disease (VOD). We prospectively analyzed the incidence of anti-HLA antibodies in 28 mismatched related pairs of recipients and their donors who underwent HCT at our center between 2020 and 2022. In positive samples screened for anti-HLA class I and/or II antibodies, the specificity of the HLA antibodies was analyzed. All recipients had a hematologic malignancy and received a myeloablative conditioning regimen and immunosuppression consisting of post-transplantation cyclophosphamide, tacrolimus, and mycophenolate mofetil. Patients were tested for TA-TMA and aGVHD development during routine post-transplantation visits up to 100 days post-transplantation. We used modified Jodele criteria for TA-TMA diagnosis, and based aGVHD grading on the MAGIC criteria. VOD was assessed using the European Society for Blood and Marrow Transplantation. Anti-HLA antibodies were detected in 12 donors (43%) and in 9 recipients (32%). There were no significant differences between donors and recipients according to age (median, 42 years [range, 17 to 69 years] versus 39 years [range, 8 to 68 years]), sex, or pregnancy history. No transfusion history was noted in the donor group (P < .05). RSA antibodies were present more often than DSAs and were detected in 9 out of 12 (75%) anti-HLA-positive donors and in only 2 out of 9 (22%) recipients, respectively (P < .05). During the follow-up, 11 patients (39%) developed aGVHD, including grade I-II in 9 (32%) and grade III-IV in 2 (7%). Twelve patients (43%) met the criteria for TA-TMA, and only 1 patient (3.5%) was diagnosed with VOD by day 100 post-HCT. RSAs were detected significantly more often in the TA-TMA group; among 12 patients diagnosed with TA-TMA, 7 (58%) had RSAs (P < .05). We did not find a correlation between RSAs and aGVHD. The patient with VOD did not have an RSA-positive donor. There was no difference in membrane attack complex (MAC) concentration in the RSA-positive group on day 30 and day 60 post-HCT; however, there was a trend toward higher MAC concentration in the RSA-positive group on day 100 (median, 912 ng/mL [range, 788 to 1120 ng/mL] versus 616 ng/mL [range, 352 to 1244 ng/mL]; P = .055). Patients with RSA suffered more often from platelet and red blood cell decreases or transfusion refractoriness, and increased lactate dehydrogenase activity was observed in all RSA-positive cases. The donor immune status and the presence of RSA may be associated with higher rates of TA-TMA in mismatched HCT recipients. Antibody-mediated complement activation might be an additional factor influencing TA-TMA occurrence.

Abstract
PTCY has been mainly used in haploidentical transplant (haploHSCT), but its use in matched donors allowed better evaluation of infectious risk conferred separately by PTCY or donor type. PTCY increased the risk of bacterial infections, both in haploidentical and matched donors, mainly pre-engraftment bacteremias. Bacterial infections, particularly due to multidrug-resistant Gram-negatives, were main causes of infection-related deaths. Higher rates of CMV and other viral infections were reported, mainly in haploHSCT. The role of donor might be more important than the role of PTCY. PTCY increased the risk of BK virus associated hemorrhagic cystitis, and seemed associated with higher risk of respiratory viral infections. Fungal infections were frequent in haploHSCT PCTY cohorts without mold active prophylaxis, but the exact role of PTCY needs to be established. Infections appear to be increased in patients receiving PTCY, although the exact role of GvHD prophylaxis and donor type can only be assessed in prospective trials.

Abstract
Hematopoietic stem cell transplantation (HSCT) is a life-saving therapy for various hematologic disorders. Due to the bone marrow suppression and its long recovery period, secondary infections, like cytomegalovirus (CMV), Epstein-Bar virus (EBV), and adenovirus (AdV), are the leading causes of morbidity and mortality in HSCT cases. Drug resistance to the antiviral pharmacotherapies makes researchers develop adoptive T cell therapies like virus-specific T cell therapy. These studies have faced major challenges such as finding the most effective T cell expansion methods, isolating the expected subtype, defining the functionality of the end-cell population, product quality control, and clinical complications after the injection. This review discusses the viral infections after HSCT, T cells characteristics during chronic viral infection, application of virus-specific T cells (VSTs) for refractory infections, standard methods for producing VSTs and their limitation, clinical experiences on VSTs, focusing on outcomes and side effects that can be helpful in decision-making for patients and further researches.

Abstract
BACKGROUND BK virus-associated hemorrhagic cystitis (BKV-HC) is a serious complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT). It can cause morbidity and may increase treatment-related mortality. Previous studies showed that the occurrence of BKV-HC was related to various factors. However, there are still many controversial factors. It is not clear whether BKV-HC will affect the long-term prognosis of patients. OBJECTIVE We aimed to identify risk factors for BKV-HC after allo-HSCT and evaluate the effect of BKV-HC on overall survival (OS) and progression- free survival (PFS) of patients. STUDY DESIGN We retrospectively analyzed the clinical data of 93 patients who underwent allo-HSCT. Univariate and multivariate analysis were used to identify risk factors for BKV-HC. The Kaplan-Meier method was used to estimate OS and PFS. A difference was considered statistically significant if P < 0.05. RESULTS A total of 24 patients developed BKV-HC. The median occurrence time of BKV-HC was 30 (range:8-89) days after transplantation, and the median duration was 25.5 (range:6-50) days. Multivariate logistic regression analysis indicated that peripheral blood lymphocyte count <1 × 109/L before conditioning (OR = 4.705, P = 0.007) and haploidentical transplantation (OR = 13.161, P = 0.018) were independent risk factors for BKV-HC. The 3-year OS rate was 85.9% (95%CI:62.1%-95.2%) in the BKV-HC group and 73.1% (95%CI: 58.2%-88.0%) in the non-BKV-HC group. There was no significant difference between the two groups (P = 0.516). The 3-year PFS rate was 76.3% (95%CI: 57.9%-94.7%) in the BKV-HC group and 58.1% (95%CI: 39.5%-76.7%) in the non-BKV-HC group. There was no significant difference in the two groups (P = 0.459). The severity of BKV-HC was not related to the OS and PFS of the patients (P value was 0.816 and 0.501, respectively). CONCLUSION Haploidentical transplantation and decreased peripheral blood lymphocyte count before conditioning increased the risk of BKV-HC after allo-HSCT. The occurrence of BKV-HC after allo-HSCT and the severity of which did not affect OS and PFS of the patients.

Abstract
Acute graft-versus-host disease (GVHD) is a common immune complication that can occur after allogeneic haematopoietic cell transplantation (alloHCT). Acute GVHD is a major health problem in these patients, and is associated with high morbidity and mortality. Acute GVHD is caused by the recognition and the destruction of the recipient tissues and organs by the donor immune effector cells. This condition usually occurs within the first 3 months after alloHCT, but later onset is possible. Targeted organs include the skin, the lower and upper gastrointestinal tract and the liver. Diagnosis is mainly based on clinical examination, and complementary examinations are performed to exclude differential diagnoses. Preventive treatment for acute GVHD is administered to all patients who receive alloHCT, although it is not always effective. Steroids are used for first-line treatment, and the Janus kinase 2 (JAK2) inhibitor ruxolitinib is second-line treatment. No validated treatments are available for acute GVHD that is refractory to steroids and ruxolitinib, and therefore it remains an unmet medical need.

Abstract
Hemorrhagic cystitis (HC) is a common complication after transplantation. The purpose of this study was to examine the incidence and risk factors for HC after hematopoietic stem cell transplantation (HSCT). The records of patients who underwent allogenic HSCT from January 2012 to December 2018 at our institution were retrospectively reviewed. Cox proportional regression and Kaplan-Meier analyses were performed to determine independent risk factors for HC. The statistical analysis was performed in May 2020. A total of 173 patients underwent HSCT, and 53 (30.6%) developed grade 2 or 3 HC cystitis at a median of 37 days (range - 5 to 98 days) after transplantation. Thirty-two patients developed moderate (grade 2) cystitis and 21 severe (grade 3) cystitis. Of the 173 patients, 61 developed acute graft-versus-host disease (GVHD) (median onset day 24) and 79 experienced cytomegalovirus (CMV) reactivation (median onset day 35). The relative risk (RR) of developing a CMV infection for patients with acute GVHD was 2.77 times that of patients without acute GVHD (P < 0.001). CMV infection was the only independent variable significantly associated with HC in both univariate and multivariate analyses. The estimated hazard ratio (HR) of CMV infection for the development of HC was 5.57 (95% confidence interval [CI]: 2.52 to 12.33, P < 0.001). CMV infection is an independent risk factor for the development of HC after HSCT, and acute GVHD is a risk factor for CMV reactivation. Decreasing the frequency of GVHD after HSCT may result in a lower frequency of HC.

Transplant Cell Ther 2023:S2666-6367(23)01174-0. [PMID: 36944387 DOI: 10.1016/j.jtct.2023.03.015] [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: 12/14/2022] [Revised: 02/06/2023] [Accepted: 03/13/2023] [Indexed: 03/23/2023]
Abstract
Haploidentical hematopoietic stem cell transplantation (haplo-HSCT) is currently an effective treatment for malignant hematological disease, but the immune deficiency and severe infection triggered by slow immune reconstitution are the main causes of high mortality and transplant failure. One of these outstanding problems is thymus damage, which is associated with graft-versus-host disease (GVHD), and preconditioning including irradiation and chemotherapy. Therefore, rapid repair of damaged thymus and rapid proliferation of thymus-derived donor T cells after transplantation are key to solving the problem. This study is designed to accelerate the recovery of thymus-derived T cells after transplantation. Wild-type mice with normal immunity were used as recipients in a haplo-HSCT mouse model to mimic clinical haplo-HSCT. A modified cell culture system using Notch ligand Delta4 and IL-7 was established that is capable of inducing and amplifying the differentiation and proliferation of hematopoietic stem cells into precursor T (preT) cells in vitro. Haplo-HSCT protocol included the preT and G-CSF mobilized donor splenic mononuclear cells (MNC) co-infusion or MNC alone. Thymic GVHD, thymic repair, and thymus-derived T cell development were compared in two groups by polychromatic immunofluorescence tracking, flow cytometry and detection of T cell receptor Vβ. The thymus homing and T-cell regeneration of allogenic preT cells were observed. The functions of preT cells in accelerating immune reconstitution, restoring thymic architecture, weakening GVH effects, and enhancing immuno-tolerance after transplantation were demonstrated. Further studies revealed that allogeneic preT cells induced by a culture system containing IL7 and Delta4 highly express ccr9 and RANKL. Interestingly, the RANK expression was promoted after preT cells' thymus homing. These results suggested that the RANK/RANKL pathway may play an important role in thymus homing. Our results provide a potential therapeutic option to optimize haplo-HSCT. It further opened up a new field of T cell therapy for artificial induction of allogeneic precursor T cells in vitro to repair the damaged thymus from irradiation and chemotherapy, and to compensate for the recovery of immune function in patients with immune deficiency caused by multiple reasons.

Abstract
BACKGROUND Since well-designed prospective comparative trials are lacking, haploidentical hematopoietic stem cell transplantations approach should be based on the expertise of a particular center. In this study, we aimed to report the results and outcomes of patients who underwent haploidentical hematopoietic stem cell transplantation. METHODS : Thirty-nine patients who underwent transplantation in our clinic between 2015 and 2022 were retrospectively analyzed. Primary end point of this study is to find out the survival rates of the patients. RESULTS The overall survival of patients was 29.9 ± 4.9 months. The disease-free survival of the patients was 37.8 ± 5.7 months. The 3-year overall survival rate of the patients was %50 and the 3-year disease-free survival rate of the patients was %53. Nineteen patients were nonsurvivors among a total of 39 patients. Busulfan-fludarabine-thiotepa was the most frequently used conditioning regimen for transplantation. Busulfan-fludarabin-antithymocyte globulin regimen is the second preferred conditioning regimen. Cyclosporine- cyclophosphamide-mycophenolate mofetil was the most widely used graft-versus-host disease prophylaxis regimen. Sixteen patients had graft-versus-host disease, 28% of the patients had acute graft-versus-host disease, and 13% had chronic graft-versus-host disease. Gastrointestinal system consists of the most involved organs in graft-versus-host disease since 15% of the patients had gastrointestinal graft-versus-host disease. First-degree relatives (parent/child) were the most frequent donor source for haploidentical hematopoietic stem cell transplantation. Sepsis was the most frequent reason of death among transplant patients. DISCUSSION In our center, we prefer to use high dose posttransplantation cyclophosphamide after haploidentical hematopoietic stem cell transplantation for graft-versus-host disease prophylaxis. With this approach, our center's overall survival and disease-free survival rates are comparable and compatible with the literature findings.

Abstract
BACKGROUND The use of prophylactic antibiotics in the pre-engraftment period to minimize the risk of bacteremia is debatable given concerns of Clostridioides difficile (C. diff), antibiotics resistance, and disruption of gut microbiota. METHODS We retrospectively reviewed the rate and characteristics of bacteremia and C. diff infections within the first 100 days post-HSCT in all pediatric patients who received routine antibacterial prophylaxis during HSCT from 2015 to 2018. C. diff infection was defined by the presence of three or more unformed stools in 24 h and positive stool test for C. diff or its toxins. RESULTS One hundred and thirty-five (100 allogeneic and 35 autologous) transplants in 123 patients were eligible for analysis. Median age at transplant was 7.1 (range 0.2-13.7), 67 (55%) were women, and diagnosis was malignant condition in 68 patients. Median time to neutrophil engraftment was 18 days (13-23). Cefepime or piperacillin-tazobactam prophylaxis was used in 105 (78%) and 28 (21%) of patients, respectively. Only five (3%) patients had bacteremia during the pre-engraftment period, and 13 (11%) patients developed bacteremia postengraftment. Septic shock was present in only one patient pre-engraftment and was due to gram-negative bacteria. All patients who developed bacteremia received MAC. Thirteen patients (10%) of patients fulfilled C. diff infection definition. There was no mortality related to bacterial infections among our patients. CONCLUSIONS The use of antibiotic prophylaxis was associated with low rate of bacteremia in the pre-engraftment period and a 10% risk of C. diff infections. More studies are needed to better evaluate the efficacy of antibiotic prophylaxis in HSCT patients.

Abstract
In recent years, with the gradual advancement of haploidentical transplantation technology, the availability of donors has increased significantly, along with the widespread use of reduced-intensity conditioning and the improvement of nursing techniques, giving more elderly acute myeloid leukemia (AML) patients the chance to receive allogeneic hematopoietic stem cell transplantation. We have summarized the classic and recently proposed pre-transplant assessment methods and assessed the various sources of donors, conditioning regimens, and post-transplant complication management based on the outcomes of large-scale clinical studies for elderly AML patients.

Abstract
BACKGROUND Hemorrhagic cystitis (HC) is a severe complication of allo-HSCT, characterized by irritative symptoms of the urinary tract and a higher morbidity rate. The risk factors and prognosis of HC are still unclear. OBJECTIVE The objective of this study is to identify risk factors and outcomes to improve treatment in pediatric SAA patients undergoing HSCTs in the Children's Hospital of Soochow University. METHODS A total of 97 SAA patients as a cohort were enrolled from 2010 to 2019 in the Children's Hospital of Soochow University and a number of factors related to HC and outcomes were analysed. In all transplants (except UCBT), patients received a combination of G-CSF stimulated bone marrow (BM) and peripheral blood stem cell (PBSC). The minimum number of CD34 + cells is 5 × 106 cells/kg. RESULTS Mononuclear cells dose (MNC, cut off: 8.53 × 108/kg) and grade II-IV acute graft versus host disease (aGVHD) were identified as independent risk factors for HC. Patients without HC had better overall survival (OS) than with HC (No HC: 98.6%±1.4% vs HC: 87.4% ± 6.8%, p = 0.03). CONCLUSION We concluded that aGVHD and MNC dose in graft might play an important role in the development of HC in pediatric SAA patients undergoing allo-HSCT. HC is also a key complication affecting the prognosis of children with SAA after allo-HSCT.

Abstract
Cytomegalovirus (CMV) reactivation is the most frequent viral infectious complication correlating to non-relapse mortality after allogeneic hematopoietic cell transplantation (alloHCT). The intrinsic anti-CMV immunity has not been completely elucidated. γδ T cells have drawn increasing attentions due to their distinct biological features and potential ability against viral infections. Previous studies reported a general association of γδ T cells or Vδ2-negative γδ T cells with CMV reactivation. Whereas researches for the direct responses and specific functions of γδ T subsets remain limited, especially in the scenario of alloHCT. Herein, we initially demonstrated that Vδ1+ T cells directly and independently recognized cell-free CMV and CMV-infected target cells, and inhibited CMV replication in vitro. The anti-CMV effect of Vδ1+ T cells was partially through TCRγδ, TLR2, and NKG2D receptor pathways. Further investigation about the anti-CMV characteristics of Vδ1+ T cells was performed in a clinical cohort with different CMV reactivation status after alloHCT. We found that occasional CMV reactivation remarkably increased the recovery levels and stimulated the functional activity of Vδ1+ T cells. Whereas disability of Vδ1+ T cells was observed upon refractory CMV reactivation, indicating the differential responses of Vδ1+ T cells under different CMV reactivation status. CXCL10 and IFN-β that were dramatically induced by occasional CMV reactivation could re-activate the deficient Vδ1+ T cells from recipients with refractory CMV reactivation. These findings unveiled the distinct activities of Vδ1+ T cells in anti-CMV immunity after alloHCT and may help develop novel strategies for the treatment of CMV infectious diseases.

Abstract
Background Infectious complications are a significant cause of morbidity and mortality in patients undergoing allogeneic haematopoietic stem cell transplantation (Allo-SCT). The BATMO (Best-Antimicrobial-Therapy-TMO) is an innovative program for infection prevention and management and has been used in our centre since 2019. The specific features of the BATMO protocol regard both prophylaxis during neutropenia (abandonment of fluoroquinolone, posaconazole use in high-risk patients, aerosolized liposomal amphotericin B use until engraftment or a need for antifungal treatment, and letermovir use in CMV-positive recipients from day 0 to day +100) and therapy (empirical antibiotics based on patient clinical history and colonization, new antibiotics used in second-line according to antibiogram with the exception of carbapenemase-producing K pneumoniae for which the use in first-line therapy is chosen). Methods Data on the infectious complications of 116 transplant patients before BATMO protocol (Cohort A; 2016 - 2018) were compared to those of 84 transplant patients following the introduction of the BATMO protocol (Cohort B; 2019 - 2021). The clinical and transplant characteristics of the 2 Cohorts were comparable, even though patients in Cohort B were at a higher risk of developing bacterial, fungal, and CMV infections, due to a significantly higher proportion of myeloablative regimens and haploidentical donors. Results No change in the incidence of infections with organ localization was observed between the two Cohorts. A significant reduction in Clostridioides difficile infections by day +100 was observed in Cohort B (47% vs. 15%; p=0.04). At day +30, a higher incidence of Gram-negative bloodstream infections (BSIs) was observed in Cohort B (12% vs. 23%; p=0.05). By day +100 and between days +100 and +180, the incidence of BSIs and of the various etiological agents, the mortality from Gram-negative bacteria, and the incidence of invasive fungal infections were not different in the two Cohorts. The incidence of CMV reactivations by day +100 dropped drastically in patients of Cohort B, following letermovir registration (51% vs. 15%; p=0.00001). Discussion The results of this study suggest that the BATMO program is safe. In particular, the choice to avoid prophylaxis with fluoroquinolone was associated with an increase in Gram-negative BSIs by day +30, but this did not translate into higher levels of mortality. Moreover, this strategy was associated with a significant reduction of Clostridiodes difficile infections. The efficacy of anti-CMV prophylaxis with letermovir was confirmed by a significant reduction in CMV reactivations. Even though patients in Cohort B were at higher risk of developing fungal infections (more haploidentical transplants with more myeloablative regimens), the extensive use of posaconazole for prophylaxis balanced this risk, and no increase in the incidence of fungal-associated complications was observed.

A Clinical Review of the Different Strategies to Minimize Hemorrhagic Cystitis Associated with the Use of Post-Transplant Cyclophosphamide in an Allogeneic Transplant. Transplant Cell Ther 2022; 28:349-354. [PMID: 35580733 DOI: 10.1016/j.jtct.2022.05.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 05/05/2022] [Accepted: 05/09/2022] [Indexed: 12/15/2022]
Abstract
Post-transplantation cyclophosphamide (PTCy) has improved hematopoietic stem cell transplantation outcomes for patients with major HLA disparities. Although PTCy in combination with calcineurin inhibitors is a successful graft-versus-host disease regimen, giving high doses of cyclophosphamide may cause hemorrhagic cystitis (HC). The strategies used to prevent HC are adapted from published data in the pre-transplantation conditioning setting. However, there is no consensus on what the optimal strategy is to prevent PTCy-associated HC. This review provides a summary of the different preventative strategies used in this setting. Based on the results published in current literature, hyperhydration is an effective preventative strategy, but it may cause fluid overload and other complications. Additionally, mesna at least 100% of the PTCy dose should be administered as a continuous infusion or frequent intermittent bolus infusion. More comparative studies between these strategies are needed to provide a definitive solution for preventing HC associated with PTCy.

Abstract
Infectious complications are the most common and significant cause of mortality and morbidity after allogeneic hematopoietic stem cell transplantation (HSCT). Antibacterial prophylaxis in pediatric cancer patients is a controversial issue. Our study compared the outcomes of levofloxacin versus ciprofloxacin prophylaxis in allogeneic HSCT pediatric recipients treated for hematological malignancies. A total of 120 patients received levofloxacin prophylaxis, and 60 patients received ciprofloxacin prophylaxis. Baseline characteristics such as age, gender, primary diagnosis, type of conditioning, donor type, stem cell source, and supportive care of the patients were similar, and duration of antibiotics prophylaxis was similar. Both prophylaxis regimens demonstrated the same efficacy on the risk of febrile neutropenia and severe complications such as sepsis, the same rate of overall mortality, hospital readmission, and length of hospital stay. Levofloxacin prophylaxis was associated with significantly lower cumulative antibiotic exposure. The median of Gram-positive infection-related antibiotic days was 10 days in the levofloxacin group versus 25 days in the ciprofloxacin group (p < 0.0001). The median of Gram-negative infection-related antibiotics was 10 days in the levofloxacin group compared with 20 days in the ciprofloxacin group (p < 0.0001). The number of days with body temperature ≥38 °C was significantly less in the levofloxacin group (p < 0.001).

The effect of granulocyte colony-stimulating factor dose and administration interval after allogeneic hematopoietic cell transplantation on early engraftment of neutrophil and platelet. J Clin Lab Anal 2021; 35:e24060. [PMID: 34674310 PMCID: PMC8649331 DOI: 10.1002/jcla.24060] [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: 06/23/2021] [Revised: 09/02/2021] [Accepted: 09/03/2021] [Indexed: 11/11/2022] Open
Abstract
BACKGROUND Hematopoietic stem cell transplantation (HSCT) is one of the treatments for hematologic malignancies. Numerous factors affect the HSCT outcome. The purpose of this study was to investigate the effect of post-HSCT administration of granulocyte colony-stimulating factor (post-G-CSF) on early neutrophil and platelet engraftment in allogeneic HSCT (allo-HSCT). MATERIAL & METHODS The study was performed on 76 patients diagnosed with AML and ALL. All patients underwent allo-HSCT at Taleghani stem cell transplantation center, Tehran, Iran, from February 2016 to December 2018. Chemotherapy regimens based on patients' conditions were selected between myeloablative and reduced-intensity regimens. RESULTS Statistical analysis revealed that the number of administered G-CSF units after HSCT was a time-dependent variable. Statistical analysis before day +11 reported that patients who received G-CSF <14 units had three times better early neutrophil engraftment than those with G-CSF ≥14 (CI 95%, AHR = 3.03, p:0.002). CD3+ cells count <318.5 × 106 /kg was associated with fast platelet engraftment (CI 95%, AHR 2.28, p:0.01). CONCLUSION In this study, post-G-CSF stimulation was associated with early engraftment in a time- and dose-dependent manner. Administration of G-CSF beyond 14 units resulted in adverse effects on neutrophil early engraftment. It also appeared that with a reduction in CD3+ cell counts, the likelihood of GVHD decreases, and platelet engraftment occurs earlier. Further investigations in the future are required to determine the factors affecting the process of early engraftment.

Abstract
Severe infections and their attributable mortality are major complications in recipients of allogeneic hematopoietic stem cell transplantation (alloSCT). We herein report 236 adult patients who received haploSCT with PTCy. The median follow-up for survivors was 37 months. The overall incidence of bloodstream infections by gram-positive and gram-negative bacteria at 37 months was 51% and 46%, respectively. The incidence of cytomegalovirus infection was 69%, while Epstein Barr virus infections occurred in 10% of patients and hemorrhagic cystitis in 35% of cases. Invasive fungal infections occurred in 11% at 17 months. The 3-year incidence of infection-related mortality was 19%. The median interval from transplant to IRM was 3 months (range 1-30), 53% of IRM occurred >100 days post-haploSCT. Risk factors for IRM included age >50 years, lymphoid malignancy, and developing grade III-IV acute GvHD. Bacterial infections were the most common causes of IRM (51%), mainly due to gram-negative bacilli BSI. In conclusion, severe infections are the most common causes of NRM after haploSCT with PTCy, with a reemergence of gram-negative bacilli as the most lethal pathogens. More studies focusing on the severe infections after haploSCT with PTCy and differences with other types of alloSCT in adults are clearly warranted.

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
Gastrointestinal bleeding (GIB) accounts for a significant proportion of life-threatening bleeding cases occurring after allogeneic haematopoietic stem cell transplantation (allo-HSCT). However, data on GIB after haploidentical HSCT (haplo-HSCT) are not available. A total of 3180 patients received haplo-HSCT at Peking University People's Hospital from January 2015 to November 2019, and GIB occurred in 188 of these patients (incidence of 5.9%). Platelet counts <30 × 109/L, viral hepatitis, acute kidney injury (AKI), gastrointestinal disease or bleeding before HSCT and sinusoidal obstruction syndrome (SOS) were determined to be significant risk factors for the occurrence of GIB after haplo-HSCT. Grade III-IV acute graft-versus-host disease (aGVHD), AKI, thrombotic microangiopathy (TMA), disseminated intravascular coagulation (DIC) and gastrointestinal disease or bleeding before HSCT were significantly related to mortality in patients with GIB after haplo-HSCT. The predictive models developed for the occurrence and mortality of GIB performed well in terms of discrimination, and they might assist clinicians with personalised strategies for GIB prevention and treatment in patients after haplo-HSCT.

Abstract
Post-transplant cyclophosphamide (PTCy) has become a promising option after allo-SCT, but infections may be more common than in traditional protocols. We herein report 117 consecutive adults who received PTCy-based alloSCT in our hospital: HaploSCT (34%), MRD (19%), and VUD (47%), respectively. The 18-month incidence of severe bacterial, viral, and IFI was 56%, 69%, and 8.7%, without differences between donor type, except for CMV infection and viral hemorrhagic cystitis, which had a higher incidence in the haploSCT cohort (58% vs. 43% and 30% vs. 8% on day +90, p < 0.05). Late infections by conventional respiratory viruses were common in all groups [33/87 (38%)]. The 2-year survival was 72% and did not differ by donor type. IRM at day 30, day 100, and 18 months was 1.7%, 4.4%, and 12%, without differences by donor type (p = 0.7). The primary cause of IRM was bacterial infection (42%). Grade 2–4 acute GvHD was the only independent predictor of IRM. Donor type had no impact on IRM or on survival. In our study, severe infections were common in all donor types using PTCy, with higher rates of early post-engraftment CMV-I and viral HC in haploSCT recipients, although lethal infections were uncommon and similar in all donor types.

Abstract
Objective: To analyze the clinical features and prognosis of cytomegalovirus pneumonia after allogeneic hematopoietic stem cell transplantation(allo-HSCT). Methods: We reviewed the clinical features and laboratory data of cytomegalovirus pneumonia patients after allogeneic peripheral blood HSCT from March 1, 2016 to June 30, 2019 at the hematology department of the Shanghai general hospital and analyze the prognostic factors. Results: Of the 411 allo-HSCT patients, 34(8.3%)developed CMV pneumonia after transplantation, including 18 men and 16 women, with a median age of 32(8-62)y. Total 14 patients had acute myeloid leukemia, 10 had acute lymphoblastic leukemia, 5 had myelodysplastic syndrome, 3 had non-Hodgkin's lymphoma, and 2 had aplastic anemia. The median onset time for CMV pneumonia was 53(36-506)d after transplantation. The main symptoms were cough(26 cases, 76.5%), fever(23 cases, 67.6%), and shortness of breath(14 cases, 41.2%). Only 17.6%(6/34)patients had expectoration, and 2 cases(5.9%)had no obvious symptoms in the early stage, but were diagnosed on routine chest CT examination. Twenty-eight(82.4%)patients showed signs of typical interstitial pneumonia, such as lobular central nodule and diffuse ground glass opacity; 6(17.6%)patients showed atypical imaging changes of patch, nodule, and consolidation. Further, 26 patients(76.5%)were positive for CMV-DNA, and the copy number was lower than that of BALF[1.70×10(7)(5.44×10(5)-4.45×10(9))copies/L vs 1.45×10(8)(1.10×10(7)-1.10×10(11))copies/L, P=0.004]. Thirteen(38.24%)patients with CMV pneumonia had mixed infection with other lower respiratory tract pathogens(10 strains of fungi, 6 strains of bacteria, and 1 of adenoviruses). The median follow-up duration was 12.8(0.4-46.5)months. The OS rate was 58.82%. Age ≥ 40 y and high flow ventilation were independent risk factors for poor prognosis in CMV pneumonia patients(P=0.049, P=0.009). Conclusion: Bronchoscopic bronchoalveolar lavage fluid detection helps in improving the accuracy of the etiological diagnosis of CMV pneumonia after allo-HSCT. Age ≥ 40 y and high flow ventilation were independent risk factors for poor prognosis in patients with CMV pneumonia.

Abstract
INTRODUCTION The accessibility to haplo-donors has led to an increase in the number of haplo-HSCT worldwide. A systematic search of the PubMed database between 2000 to present was performed. AREAS COVERED In this review, the authors discussed the most used approaches to perform haplo-HSCT and its results: T-cell depletion (TCD, including Perugia platform and its modifications) and T-cell repleted haplo (TCR, including the high-dose post-transplant cyclophosphamide strategy (Baltimore protocol) and the Beijing protocol). The improvements and modifications made to the different strategies have increased the indications of haplo-HSCT, including both malignant and nonmalignant disorders. Focusing on the Baltimore protocol, the authors review the results of the retrospective studies that have compared it to other donor transplants. The limitations of this strategy in terms of toxicity, graft complications, and GVHD are also discussed in detail. Finally, possible approaches to improve the outcomes of TCR haplo-HSCT are presented. EXPERT OPINION The recent advances in the field of haplo-HSCT have allowed a large number of patients with incurable diseases to benefit from this procedure despite not having a matched donor. With all available strategies, virtually no patient who needs an allogeneic transplant should be excluded by the absence of a donor.

Abstract
Allogeneic hematopoietic cell transplant (Allo-HCT) is a potentially curative therapy for many malignant and nonmalignant hematological diseases. However, a suitable human leukocyte antigens (HLAs)-matched donor may not be available when the patient is in urgent need of a stem cell transplant. This challenge has been ameliorated to a large extent by the introduction of haploidentical donors. This type of donor shares one HLA haplotype with the recipient. Therefore, a patient's full sibling has a 50% chance of being haploidentical and a patient's biologic parents and children will all be haploidentical, thus providing an immediately accessible, motivated donor for almost every recipient. Haploidentical transplants previously incurred prohibitively poor outcomes, preventing their widespread use. However, several recent advances have dramatically improved the results, making them a more viable donor source. In this review, we discuss different types of donors used for Allo-HCT with a particular focus on the use of haploidentical donors and their future potential.

Abstract
Background Mesenchymal stem cells (MSCs) may be used to treat steroid-refractory graft
versus host disease (GVHD). However, the effects of MSCs in haploidentical
peripheral blood stem cell transplantation (haplo-PBSCT) have not been
confirmed in randomized studies. Methods We conducted a randomized clinical study to investigate the effects of
pre-infusion (1 × 106 cells/kg) MSCs on hematopoietic recovery,
Epstein–Barr and cytomegalovirus infection, GVHD, and relapse in patients
undergoing haplo-PBSCT. Fifty patients with acute leukemia or
myelodysplastic syndrome were randomly divided into an MSC group
administered 1 × 106 MSCs/kg 4 to 6 hours before infusion of
peripheral stem cells and a control group without MSCs. Results Mean platelet engraftment time was significantly faster in the MSC compared
with the control group (12.28 vs 13.29 days). The mean neutrophil
engraftment time was comparable in both groups (10.76 ± 2.40 vs.
10.29 ± 1.72 days). Grade II or above acute GVHD was significantly decreased
in the MSC compared with the control group (12% vs. 36%). There were no
significant differences in relapse rate or overall survival between the
groups. Conclusion These results suggest that pre-infusion single-dose MSCs promote platelet
engraftment and decrease severe acute GVHD without increasing relapse
rate.

Bone Marrow Transplant 2020; 55:1906-1917. [PMID: 32346079 DOI: 10.1038/s41409-020-0897-2] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2020] [Revised: 03/15/2020] [Accepted: 03/31/2020] [Indexed: 11/08/2022]
Abstract
Aplastic anemia (AA) is a serious hematological disorder, which is solely cured by hematopoietic stem cell transplantation (HSCT). Haploidentical HSCT is an emerging modality with encouraging outcomes in several blood conditions. The present study aims to comprehensively assess the feasibility and safety of haploidentical HSCT in patients with severe and very severe AA. It is a systematic review and meta-analysis of studies related to haploidentical stem cell transplantation in idiopathic AA investigating rates of successful engraftment, acute graft-versus-host disease (aGvHD), chronic GvHD (cGvHD), transplant-related mortality (TRM), and posttransplantation viral infections (including cytomegalovirus [CMV]) in patients with AA. The effects of reduced-intensity conditioning (RIC) and nonmyeloablative conditioning (NMA), as well as various GvHD prophylaxis regimens on these outcomes were evaluated. In total 15 studies were identified, (577 patients, 58.9% males), successful engraftment was observed in 97.3% of patients (95% CI, 95.9-98.7) while grades II-IV aGvHD and cGvHD were reported in 26.6% and 25.0%, respectively. The pooled incidence of TRM was 6.7% per year (95% CI, 4.0-9.4). RIC regimens were associated with higher proportions of successful engraftment (97.7% vs 91.7%, P = 0.03) and aGvHD (29.5% vs 18.7%, P = 0.008) when compared with NMA regimens with no differences in cGvHD or mortality incidence. When compared with methotrexate-containing regimens and other regimens, posttransplant cyclophosphamide-containing regimens reduced the rates of aGvHD (28.6%, 27.8%, and 12.8%, respectively, P = 0.02), CMV viremia (55.7%, 38.6%, and 10.4%, respectively, P < 0.001), and CMV disease in initially viremic patients (2.1%, 33.0%, and 0%, respectively, P < 0.001). We have concluded that Haploidentical HSCT was associated with promising outcomes in terms of successful engraftment and reduced complications. Future prospective trials are needed to identify the preferred conditioning regimen, GvHD prophylaxis, and graft source in the setting of haploidentical transplant for AA.

Abstract
Hemorrhagic cystitis (HC) is a debilitating complication following allogenic hematopoietic cell transplantation (HCT). HLA disparity and T-cell depletion have been implicated as risk factors for HC. However, reports on the incidence and risk factors for HC in ex vivo T-cell depleted haploidentical HCT (haploHCT) in children are lacking. We studied 96 haploHCT procedures performed in 83 children between 2002 and 2017. Sixty-three patients were diagnosed with a malignant disease and 20 with nonmalignant disease. All but three patients with SCID underwent myelotoxic and/or lymphotoxic conditioning therapy. Grafts were CD3+ (36.5%) or TcRαβ+ (63.5%) depleted to prevent graft versus host disease (GvHD). Fourteen patients (14.6%) were diagnosed with HC; 12 (12.5%) had clinically significant stage II-IV HC. All patients with HC had BK viruria and/or viremia. Increasing age and chemotherapeutic treatment prior to conditioning were identified as risk factors for HC. Immune recovery did not significantly differ between patients with and without HC. Thus, we report a low incidence of HC in pediatric haploHCT using ex vivo T-cell depletion. The combination of a reduced toxicity conditioning regimen, and typically absent pharmaceutical post-HCT GvHD prophylaxis in our patients might have contributed to the decreased the risk of HC, despite HLA disparity.

Abstract
PURPOSE Patients undergoing a hematopoietic stem cell transplantation (HCT) have varied symptoms during their hospitalization. This study examined whether daily symptom reporting (with electronic patient-reported outcomes [PROs]) in an inpatient bone marrow transplant clinic reduced symptom burden on post-transplant days +7, +10, and +14. METHODS A prospective, single-institution 1:1 pilot randomized, two-arm study recruited HCT patients. HCT inpatients (N = 76) reported daily on 16 common symptoms using the PRO version of the Common Terminology for Adverse Events (PRO-CTCAE). Fisher's exact test was used to examine differences in the proportion of patients reporting individual symptoms. Multivariable linear regression modeling was used to examine group differences in peak symptom burden, while controlling for symptom burden at baseline, age, comorbidity, and transplantation type (autologous or allogeneic). RESULTS HCT patients receiving the PRO intervention also experienced lower peak symptom burden (average of 16 symptoms) at days +7, +10, and +14 (10.4 vs 14.5, p = 0.03). CONCLUSIONS Daily use of electronic symptom reporting to nurses in an inpatient bone marrow transplant clinic reduced peak symptom burden and improved individual symptoms during the 2 weeks post-transplant. A multi-site trial is warranted to demonstrate the generalizability, efficacy, and value of this intervention. TRIAL REGISTRATION ClinicalTrials.gov identifier: NCT02574897.

Abstract
Background: While haploidentical transplantation has led to the near-universal availability of donors, several challenges for this form of transplant still exist. This study sought to investigate the rates of infection-related mortality and other complications following haploidentical vs nonhaploidentical transplant. Methods: We conducted a retrospective cohort study in adults with various malignant and benign hematological conditions who underwent allogeneic hematopoietic stem cell transplantation from 2011 to 2018. One hundred-day and 1-year overall survival were defined as survival from the time of transplant until 100 days or 1 year later. Results: A total of 187 patients were included in this study, with 45 (24.1%) receiving transplants from haploidentical donors and 142 (75.9%) from nonhaploidentical donors. There were similar rates of acute graft-versus-host disease (GVHD) (40% vs 38% in haploidentical vs nonhaploidentical recipients, P=0.86) and chronic GVHD (44.4% vs 43.7%, P=1). Rates of 100-day and 1-year infection-related mortality were significantly higher in the haploidentical group compared to the nonhaploidentical group (8.9% vs 1.4% at 100 days, P=0.03, and 15.9% vs 3.8% at 1 year, P=0.01). There were also higher rates of cytomegalovirus infections (59.1% vs 23.8%, P<0.01), BK virus-associated hemorrhagic cystitis (40.9% vs 8.4%, P<0.01), and BK viremia (15.9% vs 0.8%, P<0.01) in haploidentical recipients. Conclusions: Despite the use of identical antimicrobial prophylactic and treatment agents, haploidentical recipients were found to have significantly increased rates of 100-day and 1-year infection-related mortality as well as several other infectious complications.

Abstract
Several approaches have been developed to overcome historical barriers associated with poor outcomes in the setting of HLA-haploidentical allogeneic transplantation (HaploSCT). Here, we examine the outcome of patients with various hematological disorders undergoing HaploSCT with high-dose, post-transplantation cyclophosphamide. We performed a retrospective study on 381 patients from 30 centers between January 2013 and December 2015. At the last follow-up, a total of 1058 infectious episodes were diagnosed, affecting 90.3% of the cohort. Median time to first infection was 13 days for bacterial, 32 days for viral and 20 days for fungal infections. Around 41% of these infections were of bacterial origin and 35% of viral origin, among which 48.8% of patients presented CMV reactivation. Median of GVHD relapse-free survival, progression-free survival and overall survival were 7.1 months, 19.9 months and 33.5 months, respectively. HSCT procedure was the primary or contributing cause of death (55.6%), followed by relapse of the original disease (34.2%). Infections accounted for 45.7% of the HSCT-related deaths. The present multicenter data on a large cohort of patients receiving HaploSCT with PTCy confirmed the feasibility of the procedure with an acceptable incidence of infectious complications, not different as compared to other haploidentical platforms or HLA-matched transplantation.

Abstract
Allogeneic hematopoietic stem cell transplantation is a curative treatment for many hematological diseases. However, this procedure causes the patient to be susceptible to infection. Prophylactic treatments are administered in clinical practice even thought the level of evidence of their effectiveness is not always high. In addition, changes in the transplantation procedures - use of reduced intensity conditioning, development of alternative graft sources - must lead to a rethinking of attitudes towards prophylaxis. Our working group based its recommendations on a review of referential articles and publications on the subject found in the literature. These recommendations concern the prophylaxis of infections caused by HSV1, HSV2, varicella zoster, and hepatitis B, as well as anti-bacterial and digestive decontamination prophylaxis, prevention of pneumocystis, toxoplasmosis, tuberculosis, as well as prophylaxis of fungal infections. Other infectious agents usually involved in infections post-allotransplant have been the subject of another set of recommendations from the French Society of Bone Marrow Transplantation and Cellular Therapy.

Abstract
Hematopoietic stem cell transplantation is an established treatment for patients with a wide range of malignant and nonmalignant conditions. Noninfectious pulmonary complications still remain a leading cause of morbidity and mortality in these patients. Treating hematopoietic stem cell transplantation recipients with noninfectious pulmonary complications is still challenging, and the current treatment armamentarium and strategies are not adequate for patients receiving hematopoietic stem cell transplantation. Further trials are needed for a better description of the pathogenesis and the complete diagnostic criteria as well as for the development of effective therapeutic approaches for the management of noninfectious pulmonary complications of the hematopoietic stem cell transplantation. This review outlines the incidence, risk factors, pathogenesis, and clinical spectrum and discusses the current approaches to the management of noninfectious pulmonary complications of Hematopoietic stem cell transplantation.

Abstract
Posttransplant cyclophosphamide (PTCy) has been found to be effective in ameliorating acute graft-versus-host disease (GVHD) in patients following allogeneic hematopoietic stem cell transplantation (aHSCT). Adoptive transfer of high numbers of donor Tregs in experimental aHSCT has shown promise as a therapeutic modality for GVHD regulation. We recently described a strategy for in vivo Treg expansion targeting two receptors: TNFRSF25 and CD25. To date, there have been no direct comparisons between the use of PTCy and Tregs regarding outcome and immune reconstitution within identical groups of transplanted mice. Here, we assessed these two strategies and found both decreased clinical GVHD and improved survival long term. However, recipients transplanted with Treg-expanded donor cells (TrED) exhibited less weight loss early after HSCT. Additionally, TrED recipients demonstrated less thymic damage, significantly more recent thymic emigrants, and more rapid lymphoid engraftment. Three months after HSCT, PTCy-treated and TrED recipients showed tolerance to F1 skin allografts and comparable immune function. Overall, TrED was found superior to PTCy with regard to weight loss early after transplant and initial lymphoid engraftment. Based on these findings, we speculate that morbidity and mortality after transplant could be diminished following TrED transplant into aHSCT recipients, and, therefore, that TrED could provide a promising clinical strategy for GVHD prophylaxis.

Abstract
BACKGROUND Pulmonary complications are frequent in haematologic patients. METHOD This review article summarizes the outcome of a discussion that took place during an expert meeting on the subject of pulmonary infiltrates. RESULTS AND CONCLUSIONS The most common causes of pulmonary infiltrates in haematologic patients are bacterial infections. Viral infections are subject to relevant seasonal variations, but they may also cause an important proportion of pulmonary infiltrates. Microbiological examination of respiratory tract material (if possible, bronchoalveolar lavage, BAL) is the most important diagnostic procedure. Particularly in the case of prolonged (> 7 days) neutropenia, the likelihood of infiltrates being caused by fungal infections increases. For a differential diagnosis, however, also non-infectious causes, e.g. drug-induced infiltrates, have to be taken into consideration. The diagnostic workup, however, should not delay a timely start of an adequate antimicrobial therapy.

HHV-6B infection, T-cell reconstitution, and graft-vs-host disease after hematopoietic stem cell transplantation. Bone Marrow Transplant 2018; 53:1508-1517.

Abstract
Successful and sustained CD4+ T-cell reconstitution is associated with increased survival after hematopoietic cell transplantation (HCT), but opportunistic infections may adversely affect the time and extent of immune reconstitution. Human herpesvirus 6B (HHV-6B) efficiently infects CD4+ T cells and utilizes as a receptor CD134 (OX40), a member of the TNF superfamily that antagonizes regulatory T-cell (Treg) activity. Reactivation of HHV-6B has been associated with aberrant immune reconstitution and acute graft-versus-host disease (aGVHD) after HCT. Given that Treg counts are negatively correlated with aGVHD severity, we postulate that one mechanism for the poor CD4+ T-cell reconstitution observed shortly after transplant may be HHV-6B infection and depletion of peripheral (extra-thymic) CD4+ T cells, including a subpopulation of Treg cells. In turn, this may trigger a series of adverse events resulting in poor clinical outcomes such as severe aGVHD. In addition, recent evidence has linked HHV-6B reactivation with aberrant CD4+ T-cell reconstitution late after transplantation, which may be mediated by a different mechanism, possibly related to central (thymic) suppression of T-cell reconstitution. These observations suggest that aggressive management of HHV-6B reactivation in transplant patients may facilitate CD4+ T-cell reconstitution and improve the quality of life and survival of HCT patients.

Abstract
Natural Killer (NK) cells are involved in the host immune response against infections due to viral, bacterial and fungal pathogens, all of which are a significant cause of morbidity and mortality in immunocompromised patients. Since the recovery of the immune system has a major impact on the outcome of an infectious complication, there is major interest in strengthening the host response in immunocompromised patients, either by using cytokines or growth factors or by adoptive cellular therapies transfusing immune cells such as granulocytes or pathogen-specific T-cells. To date, relatively little is known about the potential of adoptively transferring NK cells in immunocompromised patients with infectious complications, although the anti-cancer property of NK cells is already being investigated in the clinical setting. This review will focus on the antimicrobial properties of NK cells and the current standing and future perspectives of generating and using NK cells as immunotherapy in patients with infectious complications, an approach which is promising and might have an important clinical impact in the future.

Abstract
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) represents a treatment option for a diversity of advanced hematopoietic malignancies providing hope for long-term responses especially due to immunogenic effects associated with the treatment modality. Despite respectable progress in the field, relapses and/or opportunistic infections are major reasons for the high treatment-related mortality. However, a number of novel immunotherapeutic approaches using defined cell populations have been developed to directly target residual malignant cells as well as defined infectious diseases. We here provide an overview of current adoptive cellular immunotherapies in the context of allo-HSCT and close with an outlook on new directions within the field.
