Abstract
Patients with poor graft function (PGF) or declining donor chimerism (DC) post allogeneic hematopoietic cell transplantation (HCT) may benefit from a CD34-selected stem cell boost (SCB). We retrospectively studied outcomes of fourteen pediatric patients (PGF: 12 and declining DC: 2), with a median age of 12.8 (range 0.08-20.6) years at HCT, who received a SCB. Primary and secondary endpoints included resolution of PGF or improvement in DC (≥ 15% increase), overall survival (OS) and transplant-related mortality (TRM), respectively. The median CD34 dose infused was 7.47 × 106/kg (range 3.51 × 106-3.39 × 107/kg). Among patients with PGF who survived ≥ 3 months post-SCB (n = 8), we observed a non-significant decrease in the cumulative median number of red cell transfusions, platelet transfusions, and GCSF but not intravenous immunoglobulin doses in the 3 months before and after SCB. Overall response rate (ORR) was 50%, with 29% complete and 21% partial responses. ORR was better in recipients who received lymphodepletion (LD) pre-SCB versus none (75% versus 40%; p = 0.56). The incidence of acute and chronic graft-versus-host-disease was 7% and 14%, respectively. The 1-year OS was 50% (95% CI 23-72%) and TRM was 29% (95% CI 8-58%). SCB was effective in half of our cohort with possible benefit of LD pre-SCB.

Comparison of hematopoietic cell transplant conditioning regimens for hemophagocytic lymphohistiocytosis disorders. J Allergy Clin Immunol 2022; 149:1097-1104.e2.

Abstract
BACKGROUND Allogeneic hematopoietic cell transplantation for hemophagocytic lymphohistiocytosis (HLH) disorders is associated with substantial morbidity and mortality. OBJECTIVE The effect of conditioning regimen groups of varying intensity on outcomes after transplantation was examined to identify an optimal regimen or regimens for HLH disorders. METHODS We studied 261 patients with HLH disorders transplanted between 2005 and 2018. Risk factors for transplantation outcomes by conditioning regimen groups were studied by Cox regression models. RESULTS Four regimen groups were studied: (1) fludarabine (Flu) and melphalan (Mel) in 123 subjects; (2) Flu, Mel, and thiotepa (TT) in 28 subjects; (3) Flu and busulfan (Bu) in 14 subjects; and (4) Bu and cyclophosphamide (Cy) in 96 subjects. The day 100 incidence of veno-occlusive disease was lower with Flu/Mel (4%) and Flu/Mel/TT (0%) compared to Flu/Bu (14%) and Bu/Cy (22%) (P < .001). The 6-month incidence of viral infections was highest after Flu/Mel (72%) and Flu/Mel/TT (64%) compared to Flu/Bu (39%) and Bu/Cy (38%) (P < .001). Five-year event-free survival (alive and engrafted without additional cell product administration) was lower with Flu/Mel (44%) compared to Flu/Mel/TT (70%), Flu/Bu (79%), and Bu/Cy (61%) (P = .002). The corresponding 5-year overall survival values were 68%, 75%, 86%, and 64%, and did not differ by conditioning regimen (P = .19). Low event-free survival with Flu/Mel is attributed to high graft failure (42%) compared to Flu/Mel/TT (15%), Flu/Bu (7%), and Bu/Cy (18%) (P < .001). CONCLUSIONS Given the high rate of graft failure with Flu/Mel and the high rate of veno-occlusive disease with Bu/Cy and Flu/Bu, Flu/Mel/TT may be preferred for HLH disorders. Prospective studies are warranted.

Abstract
Defects in DNA cross-link repair 1C (DCLRE1C), protein kinase DNA activated catalytic polypeptide (PRKDC), ligase 4 (LIG4), NHEJ1, and NBS1 involving the nonhomologous end-joining (NHEJ) DNA repair pathway result in radiation-sensitive severe combined immunodeficiency (SCID). Results of hematopoietic cell transplantation for radiation-sensitive SCID suggest that minimizing exposure to alkylating agents and ionizing radiation is important for optimizing survival and minimizing late effects. However, use of preconditioning with alkylating agents is associated with a greater likelihood of full T- and B-cell reconstitution compared with no conditioning or immunosuppression alone. A reduced-intensity regimen using fludarabine and low-dose cyclophosphamide might be effective for patients with LIG4, NHEJ1, and NBS1 defects, although more data are needed to confirm these findings and characterize late effects. For patients with mutations in DCLRE1C (Artemis-deficient SCID), there is no optimal approach that uses standard dose-alkylating agents without significant late effects. Until nonchemotherapy agents, such as anti-CD45 or anti-CD117, become available, options include minimizing exposure to alkylators, such as single-agent low-dose targeted busulfan, or achieving T-cell reconstitution, followed several years later with a conditioning regimen to restore B-cell immunity. Gene therapy for these disorders will eventually remove the issues of rejection and graft-versus-host disease. Prospective multicenter studies are needed to evaluate these approaches in this rare but highly vulnerable patient population.

Alpha/beta T-cell depleted grafts as an immunological booster to treat graft failure after hematopoietic stem cell transplantation with HLA-matched related and unrelated donors.

Abstract
Allogeneic hematopoietic stem cell transplantation is associated with several complications and risk factors, for example, graft versus host disease (GVHD), viral infections, relapse, and graft rejection. While high levels of CD3+ cells in grafts can contribute to GVHD, they also promote the graft versus leukemia (GVL) effect. Infusions of extra lymphocytes from the original stem cell donor can be used as a treatment after transplantation for relapse or poor immune reconstitution but also they increase the risk for GVHD. In peripheral blood, 95% of T-cells express the αβ T-cell receptor and the remaining T-cells express the γδ T-cell receptor. As αβ T-cells are the primary mediators of GVHD, depleting them from the graft should reduce this risk. In this pilot study, five patients transplanted with HLA-matched related and unrelated donors were treated with αβ T-cell depleted stem cell boosts. The majority of γδ T-cells in the grafts expressed Vδ2 and/or Vγ9. Most patients receiving αβ-depleted stem cell boosts increased their levels of white blood cells, platelets, and/or granulocytes 30 days after infusion. No signs of GVHD or other side effects were detected. A larger pool of patients with longer follow-up time is needed to confirm the data in this study.

Abstract
Severe combined immunodeficiency (SCID) is a fatal syndrome caused by mutations in at least 13 different genes. It is characterized by the absence of T-cells. Immune reconstitution can be achieved through non-ablative related donor bone marrow transplantation. However, the first transplant may not provide sufficient immunity. In these cases, booster transplants may be helpful. A prospective/retrospective study was conducted of 49 SCID patients (28.7 percent of 171 SCIDs transplanted over 30 years) who had received booster transplants to define the long term outcome, factors contributing to a need for a booster and factors that predicted success. Of the 49 patients, 31 (63 percent) are alive for up to 28 years. Age at initial transplantation was found to have a significant effect on outcome (mean of 194 days old for patients currently alive, versus a mean of 273 days old for those now deceased, p=0.0401). Persistent viral infection was present in most deceased booster patients. In several patients, the use of two parents as sequential donors resulted in striking T and B cell immune reconstitution. A majority of the patients alive today have normal or adequate T-cell function and are healthy. Non-ablative booster bone marrow transplantation can be life-saving for SCID.

Abstract
Omenn's syndrome is a rare inherited variant of SCID. It is inevitably fatal, unless treated by bone marrow or stem cell transplantation. However, treatment-related complications and graft rejection are major obstacles to the success of transplantation. In this report, we describe an eight-month-old baby with Omenn's syndrome and disseminated BCGosis, who underwent allogenic BMT from his HLA-matched sister using anti-GVHD prophylaxis but without a conditioning regimen. Ten days after BMT, he developed acute GVHD involving the skin only (grade 1) with a flare of local BCGosis. Engraftment of 55% was demonstrated by FISH as early as the 11th day post-BMT. On day +48 post-BMT, he developed GVHD that was complicated by refractory pancytopenia, resistant to three doses of rituximab. Patient was re-transplanted (from the same donor) after receiving fludarabine and ATG, with successful engraftment and complete recovery from pancytopenia.

Abstract
Haemophagocytic lymphohistiocytosis (HLH) is a life-threatening immunodeficiency characterized by severe systemic hyper-inflammatory responses to infectious or other triggers of the immune system. In many patients, the underlying cause of HLH is a genetic defect leading to defective CD8(+) T cell and natural killer cell granule-mediated cytotoxicity. The treatment of HLH consists principally of immune suppression followed by allogeneic haematopoietic cell transplantation (HCT) to cure the underlying defect and prevent relapse of HLH. Initial treatment regimens consist of steroids coupled with either etoposide or antithymocyte globulin, ± ciclosporin. Complete responses are observed in only 50-75% of patients and even after a complete response, relapse and death still occur. The only definitive, long-term cure for patients with genetic forms of HLH is allogeneic HCT. Unfortunately, allogeneic HCT for patients with HLH is often complicated by critical illness, extensive organ involvement, active infections, or refractory HLH. For these reasons, patients are unusually prone to developing transplant-related toxicities and complications. In recent years, great strides have been made with regard to the care and transplantation of patients with HLH. Here we review the current state of the treatment of patients with HLH with allogeneic HCT, highlighting the important steps forward that have been made with reduced-intensity conditioning.

Abstract
X-linked lymphoproliferative disease (XLP1), described in the mid-1970s and molecularly defined in 1998, and XLP2, reported in 2006, are prematurely lethal genetic immunodeficiencies that share susceptibility to overwhelming inflammatory responses to certain infectious triggers. Signaling lymphocytic activation molecule-associated protein (SAP; encoded by SH2D1A) is mutated in XLP1, and X-linked inhibitor of apoptosis (XIAP; encoded by BIRC4) is mutated in XLP2. XLP1 is a disease with multiple and variable clinical consequences, including fatal hemophagocytic lymphohistiocytosis (HLH) triggered predominantly by Epstein-Barr virus, lymphomas, antibody deficiency, and rarer consequences of immune dysregulation. To date, XLP2 has been found to cause HLH with and without exposure to Epstein-Barr virus, and HLH is commonly recurrent in these patients. For both forms of XLP, the only curative therapy at present is allogeneic hematopoietic cell transplantation. Beyond their common X-linked locus and their requirement for normal immune responses to certain viral infections, SAP and XIAP demonstrate no obvious structural or functional similarity, are not coordinately regulated with respect to their expression, and do not appear to directly interact. In this review, we describe the genetic, clinical, and immunopathologic features of these 2 disorders and discuss current diagnostic and therapeutic strategies.

Abstract
Rapid progress has been made from the identification of the molecular defects causing X-linked severe combined immune deficiency (X-SCID) to the development of cutting-edge therapeutic approaches such as hematopoietic stem cell transplant and gene therapy for XSCID. Successful treatment of XSCID has created a new population of patients, many of whom are now adolescents and young adults and are facing a variety of chronic problems secondary to partial correction of their underlying disease. This review focuses on the clinical challenges facing these patients (and their caregivers) and provides an overview of some of the treatment options available, including gene therapy.

Abstract
Haploidentical hematopoietic stem cell transplant with T-cell depletion may result in donor T-cell engraftment in infants with severe combined immunodeficiency disease. Engraftment of other hematopoietic lines is achieved rarely, and pancytopenia and hemophagocytosis as a result of donor T-cell engraftment have not been reported. We report an infant with severe combined immunodeficiency who developed graft versus host disease with pancytopenia as a result of engraftment of maternal T cells after T-depleted hematopoietic stem cell transplant. His pancytopenia resolved after thymoglobulin and a stem cell boost. Thrombocytopenia resolved with rituximab.

Abstract
The molecular bases of most primary immunodeficiencies (PID) have been discovered. Long-term follow-up of patient cohorts treated with antimicrobial prophylaxis has demonstrated good short-term prognosis but with increasing morbidity and mortality over time. The results of hematopoietic stem cell transplantation (HSCT) for PID have improved incrementally over time, with survival and cure of 90% for some defined diseases. This article examines the advances in HSCT for PID and argues that HSCT should be considered earlier for most patients.

Abstract
BACKGROUND Results of treatment of severe T-lymphocyte immunodeficiencies by means of hematopoietic stem cell (HSC) transplantation have improved. T cell-depleted haploidentical transplantations are successful if there is no HLA-identical donor. Methods to remove T lymphocytes include addition of anti-CD52 antibodies and CD34(+) HSC selection. OBJECTIVE Assessment of long-term immune function is important after these treatments. We looked at immune reconstitution in 36 survivors for more than 2 years after HSC transplantation for severe T-lymphocyte immunodeficiencies and compared engraftment quality between the 2 T-lymphocyte depletion methods. METHODS Chimerism, T- and B-lymphocyte subsets, immunoglobulin levels, and specific antibody production at last follow-up were examined. The chi(2) (Fisher exact test) and Wilcoxon rank sum analyses were used to compare the groups. RESULTS Nineteen patients received anti-CD52-treated and 19 anti-CD34-treated HSCs. More anti-CD52-treated patients had full donor myeloid chimerism (P = .025). All patients had full donor T-lymphocyte chimerism. There was no difference in donor B-lymphocyte chimerism, but significantly more anti-CD52-treated patients had class-switched memory B lymphocytes (P = .024), normal IgG levels, and normal responses to tetanus and Haemophilus influenzae type B vaccination. More anti-CD52-treated patients with common gamma chain or Janus-associated kinase 3 severe combined immunodeficiency had donor B lymphocytes. CONCLUSION Long-term T-lymphocyte function is good with either treatment method, with a low incidence of graft-versus-host disease. The results imply more incomplete donor chimerism in anti-CD34-treated patients with less B-lymphocyte function.

Abstract
Lymphoproliferative disease (LPD) is a recognized complication of primary immunodeficiency (PID) and immunodysregulatory syndromes. Historically, it has a very poor outcome. For patients surviving LPD, myeloablative hematopoietic stem cell transplantation (SCT) was the only cure for the underlying PID, with a high risk of developing posttransplantation complications, including recurrent lymphoproliferative disease. We describe 8 patients with a range of PID and immunodysregulatory syndromes complicated by LPD. After initial treatment of the LPD (including the use of anti-CD20 monoclonal antibody, rituximab, in 6 of the patients), all patients underwent reduced-intensity conditioning (RIC) SCT with prospective monitoring for Epstein-Barr virus (EBV) viremia. After transplantation, 3 patients received rituximab, and 3 patients received prophylactic EBV-specific cytotoxic T-lymphocytes. Only 1 patient developed recurrent LPD posttransplantation, which responded to rituximab. All patients who underwent transplantation survive free of LPD and are cured of their PID at a median follow-up of 4 years (range, 1-7 years). With careful monitoring and pre-emptive therapy, we advocate this RIC SCT approach to patients with PID who have pre-existing EBV-LPD.

Abstract
Haematopoietic stem cell transplantation can be limited by ineffective haematopoiesis and poor immune recovery. A CD34(+) cell infusion without conditioning has the potential to improve stem cell function with limited toxicity. Eighteen patients with congenital immunodeficiencies received CD34(+) boosts for various defects. When given <1 year after the original graft, six of seven cytopenic patients achieved transfusion independence. A second cohort (n = 11) received boosts >1 year after the original graft; only minimal changes in immune function or chimaerism were noted. Unconditioned stem cell boosts have limited toxicity but should be given early after the original graft to be effective.

Abstract
Primary immunodeficiencies (PIDs) are a rare but important cause of mortality and morbidity in childhood: the most severe--known as severe combined immunodeficiency (SCID)--are fatal within the first year of life; other PIDs are less immediately life-threatening, but have a poor long-term outlook. Haematopoietic stem cell transplantation (HSCT) is the best treatment for SCID and is increasingly offered for other PIDs. The best results are achieved with an HLA-matched family donor. Umbilical cord stem cells (UCSCs) are an alternative stem cell source. Results using UCSCs in the treatment of haematological disorders and malignancy are as good as those for which marrow is the stem cell source. Although PIDs make up a small proportion of disorders amenable to treatment by HSCT, UCSCs are an ideal source of haematopoietic stem cells for many of these patients. Of the 52 patients with SCID or other PIDs for whom detailed information on outcome is available, results of engraftment, immune reconstitution, incidence of graft-versus-host disease and survival are comparable with other stem cell sources. Small stem cell dose and prolonged time to viral immunity limit the patients for whom UCSCs can be used. Newer methods of achieving better engraftment, ex vivo expansion of stem cells and generation of antigen-specific cytotoxic T cells are being developed at present, and will widen the application of UCSCs as a viable source for more patients.

Abstract
Unrelated cord blood (UCB) hematopoietic stem cells were serially transplanted into two human leukocyte antigen (HLA)-identical siblings with T cell, B cell, natural killer cell severe combined immunodeficiency. Brother A received a 4/6-matched, HLA DRbeta1-identical but class I-disparate UCB graft after myeloablative dosages of busulfan, melphalan, and antithymocyte globulin. He experienced complete donor chimerism, severe acute gastrointestinal graft-versus-host disease (GVHD), and limited chronic skin GVHD that resolved with treatment. Two years later, brother B received unfractionated marrow from brother A after reduced-intensity conditioning with cyclophosphamide and antithymocyte globulin. Brother B experienced mixed-donor (i.e. original UCB) chimerism and no histologically documented GVHD. Both brothers are clinically well; brother A is in a fully immunologically reconstituted state. The uneventful course and progressive increase in donor chimerism after the second transplantation indicates that hematopoietic cells derived from the older brother's marrow engrafted without causing GVHD, suggesting that acquired tolerance to disparate unrelated HLA antigens was achieved.

Abstract
There is an abundance of clinical applications using human umbilical cord blood (HUCB) as a source for stem cell populations. Other than haematopoietic progenitors, there are mesenchymal, endothelial stem cells and neuronal precursors, in varying quantities, that are found in human umbilical cord blood. These may be useful in diseases such as immune deficiency and autoimmune disorders. Considering issues of safety, availability, transplant methodology, rejection and side effects, it is contended that a therapeutic stem cell transplant, utilizing stem cells from HUCB, provides a reliable repository of early precursor cells that can be useful in a great number of diverse conditions. Drawbacks of relatively smaller quantities of mononucleated cells in one unit of cord blood can be mitigated by in-vitro expansion procedures, improved in-vivo signalling, and augmentation of the cellular milieu, while simultaneously choosing the appropriate transplantation site and technique for introduction of the stem cell graft.
