Abstract
BACKGROUND X-linked agammaglobulinemia (XLA) is an inborn error of immunity that renders boys susceptible to life-threatening infections due to loss of mature B cells and circulating immunoglobulins. It is caused by defects in the gene encoding the Bruton tyrosine kinase (BTK) that mediates the maturation of B cells in the bone marrow and their activation in the periphery. This paper reports on a gene editing protocol to achieve "knock-in" of a therapeutic BTK cassette in hematopoietic stem and progenitor cells (HSPCs) as a treatment for XLA. METHODS To rescue BTK expression, this study employed a clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9 system that creates a DNA double-strand break in an early exon of the BTK locus and an adeno-associated virus 6 virus that carries the donor template for homology-directed repair. The investigators evaluated the efficacy of the gene editing approach in HSPCs from patients with XLA that were cultured in vitro under B-cell differentiation conditions or that were transplanted in immunodeficient mice to study B-cell output in vivo. RESULTS A (feeder-free) B-cell differentiation protocol was successfully applied to blood-mobilized HSPCs to reproduce in vitro the defects in B-cell maturation observed in patients with XLA. Using this system, the investigators could show the rescue of B-cell maturation by gene editing. Transplantation of edited XLA HSPCs into immunodeficient mice led to restoration of the human B-cell lineage compartment in the bone marrow and immunoglobulin production in the periphery. CONCLUSIONS Gene editing efficiencies above 30% could be consistently achieved in human HSPCs. Given the potential selective advantage of corrected cells, as suggested by skewed X-linked inactivation in carrier females and by competitive repopulating experiments in mouse models, this work demonstrates the potential of this strategy as a future definitive therapy for XLA.

Abstract
The transcription factor STAT6 (Signal Transducer and Activator of Transcription 6) is a key regulator of Th2 (T-helper 2) mediated allergic inflammation via the IL-4 (interleukin-4) JAK (Janus kinase)/STAT signalling pathway. We identified a novel heterozygous germline mutation STAT6 c.1255G > C, p.D419H leading to overactivity of IL-4 JAK/STAT signalling pathway, in a kindred affected by early-onset atopic dermatitis, food allergy, eosinophilic asthma, anaphylaxis and follicular lymphoma. STAT6 D419H expression and functional activity were compared with wild type STAT6 in transduced HEK293T cells and to healthy control primary skin fibroblasts and peripheral blood mononuclear cells (PBMC). We observed consistently higher STAT6 levels at baseline and higher STAT6 and phosphorylated STAT6 following IL-4 stimulation in D419H cell lines and primary cells compared to wild type controls. The pSTAT6/STAT6 ratios were unchanged between D419H and control cells suggesting that elevated pSTAT6 levels resulted from higher total basal STAT6 expression. The selective JAK1/JAK2 inhibitor ruxolitinib reduced pSTAT6 levels in D419H HEK293T cells and patient PBMC. Nuclear staining demonstrated increased STAT6 in patient fibroblasts at baseline and both STAT6 and pSTAT6 after IL-4 stimulation. We also observed higher transcriptional upregulation of downstream genes (XBP1 and EPAS1) in patient PBMC. Our study confirms STAT6 gain of function (GOF) as a novel monogenetic cause of early onset atopic disease. The clinical association of lymphoma in our kindred, along with previous data linking somatic STAT6 D419H mutations to follicular lymphoma suggest that patients with STAT6 GOF disease may be at higher risk of lymphomagenesis.245 words.

Abstract
Patients with haematological malignancies are more likely to have poor responses to vaccination. Here we provide detailed analysis of the humoral and cellular responses to COVID-19 vaccination in 69 patients with B-cell malignancies. Measurement of anti-spike IgG in serum demonstrated a low seroconversion rate with 27.1% and 46.8% of patients seroconverting after the first and second doses of vaccine, respectively. In vitro pseudoneutralisation assays demonstrated a poor neutralising response, with 12.5% and 29.5% of patients producing a measurable neutralising titre after the first and second doses, respectively. A third dose increased seropositivity to 54.3% and neutralisation to 51.5%, while a fourth dose further increased both seropositivity and neutralisation to 87.9%. Neutralisation titres post-fourth dose showed a positive correlation with the size of the B-cell population measured by flow cytometry, suggesting an improved response correlating with recovery of the B-cell compartment after B-cell depletion treatments. In contrast, interferon gamma ELISpot analysis showed a largely intact T-cell response, with the percentage of patients producing a measurable response boosted by the second dose to 75.5%. This response was maintained thereafter, with only a small increase following the third and fourth doses, irrespective of the serological response at these timepoints.

Abstract
PURPOSE There is a lack of data on post-HSCT non-osteopenic bone pathology specifically for children with inborn errors of immunity (IEI). We collected data on non-osteopenic bone pathology in children with IEI post-HSCT over two decades in a large tertiary pediatric immunology center. METHODS Descriptive study with data analysis of bone pathology in allo-HSCT for IEI was performed between 1/1/2000 to 31/12/2018 including patients alive at follow-up to July 2022. Records were analyzed for bone pathology and risk factors. Exclusion criteria included isolated reduced bone density, fractures, and skeletal anomalies due to underlying IEI and short stature without other bone pathology. Bone pathologies were divided into 5 categories: bone tumors; skeletal dysplasia; avascular necrosis; evolving bone deformities; slipped upper femoral epiphysis. RESULTS A total of 429 children received HSCT between 2000 and 2018; 340 are alive at last assessment. Non-osteopenic bone pathology was observed post-HSCT in 9.4% of patients (32/340, mean 7.8 years post-HSCT). Eleven patients (34%) had > 1 category of bone pathology. Seventeen patients (17/32; 53%) presented with bilateral bone pathology. The majority of patients received treosulfan-based conditioning (26/32; 81.2%). Totally, 65.6% (21/32) of patients had a history of prolonged steroid use (> 6 months). Pain was the presenting symptom in 66% of patients, and surgical intervention was required in 43.7%. The highest incidence of bone pathologies was seen in Wiskott-Aldrich syndrome (WAS) (n = 8/34; 23.5%) followed by hemophagocytic lymphohistiocytosis patients (n = 3/16; 18.8%). CONCLUSION Non-osteopenic bone pathology in long-term survivors of allo-HSCT for IEI is not rare. Most patients did not present with complaints until at least 5 years post-HSCT highlighting the need for ongoing bone health assessment for patients with IEI. Children presenting with stunted growth and bone pathology post-HSCT should undergo skeletal survey to rule out development of post-HSCT skeletal dysplasia. Increased rates and complexity of bone pathology were seen amongst patients with Wiskott-Aldrich syndrome.

Abstract
STAT6 (signal transducer and activator of transcription 6) is a transcription factor that plays a central role in the pathophysiology of allergic inflammation. We have identified 16 patients from 10 families spanning three continents with a profound phenotype of early-life onset allergic immune dysregulation, widespread treatment-resistant atopic dermatitis, hypereosinophilia with esosinophilic gastrointestinal disease, asthma, elevated serum IgE, IgE-mediated food allergies, and anaphylaxis. The cases were either sporadic (seven kindreds) or followed an autosomal dominant inheritance pattern (three kindreds). All patients carried monoallelic rare variants in STAT6 and functional studies established their gain-of-function (GOF) phenotype with sustained STAT6 phosphorylation, increased STAT6 target gene expression, and TH2 skewing. Precision treatment with the anti-IL-4Rα antibody, dupilumab, was highly effective improving both clinical manifestations and immunological biomarkers. This study identifies heterozygous GOF variants in STAT6 as a novel autosomal dominant allergic disorder. We anticipate that our discovery of multiple kindreds with germline STAT6 GOF variants will facilitate the recognition of more affected individuals and the full definition of this new primary atopic disorder.

Abstract
CD28 and CTLA-4 (CD152) play essential roles in regulating T cell immunity, balancing the activation and inhibition of T cell responses, respectively. Although both receptors share the same ligands, CD80 and CD86, the specific requirement for two distinct ligands remains obscure. In the present study, we demonstrate that, although CTLA-4 targets both CD80 and CD86 for destruction via transendocytosis, this process results in separate fates for CTLA-4 itself. In the presence of CD80, CTLA-4 remained ligand bound, and was ubiquitylated and trafficked via late endosomes and lysosomes. In contrast, in the presence of CD86, CTLA-4 detached in a pH-dependent manner and recycled back to the cell surface to permit further transendocytosis. Furthermore, we identified clinically relevant mutations that cause autoimmune disease, which selectively disrupted CD86 transendocytosis, by affecting either CTLA-4 recycling or CD86 binding. These observations provide a rationale for two distinct ligands and show that defects in CTLA-4-mediated transendocytosis of CD86 are associated with autoimmunity.

Abstract
BACKGROUND Hematopoietic stem cell transplant (HSCT) is well established as a corrective treatment for many inborn errors of immunity (IEIs) presenting in childhood. Due to improved techniques, more transplants are undertaken and patients are living longer. However, long-term complications can significantly affect future health and quality of life. Previous research has focused on short-term medical outcomes and little is known about health or psychosocial outcomes in adulthood. OBJECTIVE This project aimed to ascertain the long-term social and psychological outcomes for adults who underwent HSCT for IEI during childhood. METHODS Adult patients, who had all undergone HSCT for IEI during childhood at two specialist immunology services at least 5 years previously, were invited to participate in the study. Questionnaires and practical tasks assessed their current functioning and circumstances. Information was also gathered from medical notes. Data was compared with population norms and a control group of participant-nominated siblings or friends. RESULTS Eighty-three patients and 46 matched controls participated in the study. Patients reported significantly better physical health-related quality of life than the general population norm, but significantly worse than matched controls. Patient's self-reported physical health status and the perceived impact of their physical health on everyday life were worse than matched controls and patients reported higher levels of anxiety and lower mood than the general population. For those where their IEI diagnosis was not associated with a learning disability, cognitive function was generally within the normal range. CONCLUSIONS Patients who have had a HSCT in childhood report mixed psychosocial outcomes in adulthood. More research is needed to establish screening protocols and targeted interventions to maximize holistic outcomes. CLINICAL IMPLICATIONS Screening for holistic needs and common mental health difficulties should be part of routine follow-up. Information should be provided to patients and families in order to support decision-making regarding progression to transplant and the early identification of any difficulties.

Abstract
Purpose
Allogeneic hematopoietic stem cell transplant (HSCT) remains the treatment of choice for patients with inborn errors of immunity (IEI). There is little published medical outcome data assessing late medical complications following transition to adult care. We sought to document event-free survival (EFS) in transplanted IEI patients reaching adulthood and describe common late-onset medical complications and factors influencing EFS. Methods In this landmark analysis, 83 adults surviving 5 years or more following prior HSCT in childhood for IEI were recruited. The primary endpoint was event-free survival, defined as time post-first HSCT to graft failure, graft rejection, chronic infection, life-threatening or recurrent infections, malignancy, significant autoimmune disease, moderate to severe GVHD or major organ dysfunction. All events occurring less than 5 years post-HSCT were excluded. Results EFS was 51% for the whole cohort at a median of 20 years post HSCT. Multivariable analysis identified age at transplant and whole blood chimerism as independent predictors of long-term EFS. Year of HSCT, donor, conditioning intensity and underlying diagnosis had no significant impact on EFS. 59 events occurring beyond 5 years post-HSCT were documented in 37 patients (45% cohort). A total of 25 patients (30% cohort) experienced ongoing significant complications requiring active medical intervention at last follow-up. Conclusion Although most patients achieved excellent, durable immune reconstitution with infrequent transplant-related complications, very late complications are common and associated with mixed chimerism post-HSCT. Early intervention to correct mixed chimerism may improve long-term outcomes and adult health following HSCT for IEI in childhood.

Abstract
BACKGROUND X-linked inhibitor of apoptosis (XIAP) deficiency is a rare, primary immunodeficiency disease caused by XIAP gene mutations. A broad range of phenotype, severity, and age of onset present challenges for patient management. OBJECTIVE To characterize the phenotype, treatment, and survival outcomes of XIAP deficiency and assess parameters influencing prognosis. METHODS Data published from 2006-2020 were retrospectively analyzed. RESULTS 167 patients from 117 families with XIAP deficiency were reported with 90 different mutations. A wide spectrum of clinical features were seen, of which hemophagocytic lymphohistiocytosis (HLH) and inflammatory bowel disease (IBD) were the most common. Patients frequently developed multiple features with no clear genotype-phenotype correlation. 117 patients were managed conservatively and 50 underwent hematopoietic stem cell transplantation (HSCT), with respective overall survival probabilities of 90% and 53% at age 16 years. The predominant indication for HSCT was early-onset HLH. Active HLH and myeloablative conditioning regimens increased HSCT-related mortality, although HSCT outcome was much better after 2015 than before. For conservatively managed patients reaching adulthood, survival probabilities were 86% at age 30 years and 37% by age 52 years, with worse outcomes for patients developing the disease before the age of 5 years or with new disease features in adulthood. 9 asymptomatic mutation carriers were identified with a median age of 13.5 years. CONCLUSIONS Our study demonstrates the variable nature of XIAP deficiency which evolves over life for individual patients. Better therapeutic strategies and prospective studies are required to reduce morbidity and mortality and improve decision-making and long-term outcomes for patients with XIAP deficiency.

Abstract
X-linked inhibitor of apoptosis (XIAP) deficiency is an inherited primary immunodeficiency characterized by chronic inflammasome overactivity and associated with hemophagocytic lymphohistiocytosis (HLH) and inflammatory bowel disease (IBD). Allogeneic hematopoietic cell transplantation (HCT) with fully myeloablative conditioning may be curative but has been associated with poor outcomes. Reports of reduced-intensity conditioning (RIC) and reduced-toxicity conditioning (RTC) regimens suggest these approaches are well tolerated, but outcomes are not well established. Retrospective data were collected from an international cohort of 40 patients with XIAP deficiency who underwent HCT with RIC or RTC. Thirty-three (83%) patients had a history of HLH, and thirteen (33%) patients had IBD. Median age at HCT was 6.5 years. Grafts were from HLA-matched (n = 30, 75%) and HLA-mismatched (n = 10, 25%) donors. There were no cases of primary graft failure. Two (5%) patients experienced secondary graft failure, and three (8%) patients ultimately received a second HCT. Nine (23%) patients developed grade II–IV acute GVHD, and 3 (8%) developed extensive chronic GVHD. The estimated 2-year overall and event-free survival rates were 74% (CI 55–86%) and 64% (CI 46–77%), respectively. Recipient and donor HLA mismatch and grade II–IV acute GVHD were negatively associated with survival on multivariate analysis with hazard ratios of 5.8 (CI 1.5–23.3, p = 0.01) and 8.2 (CI 2.1–32.7, p < 0.01), respectively. These data suggest that XIAP patients tolerate RIC and RTC with survival rates similar to HCT of other genetic HLH disorders. Every effort should be made to prevent acute GVHD in XIAP-deficient patients who undergo allogeneic HCT.

Abstract
Background: Activated phosphoinositide 3-kinase delta syndrome (APDS) is a combined immunodeficiency with a heterogeneous phenotype considered reversible by allogeneic hematopoietic cell transplantation (HCT). Objectives: This study sought to characterize HCT outcomes in APDS. Methods: Retrospective data were collected on 57 patients with APDS1/2 (median age, 13 years; range, 2–66 years) who underwent HCT. Results: Pre-HCT comorbidities such as lung, gastrointestinal, and liver pathology were common, with hematologic malignancy in 26%. With median follow-up of 2.3 years, 2-year overall and graft failure–free survival probabilities were 86% and 68%, respectively, and did not differ significantly by APDS1 versus APDS2, donor type, or conditioning intensity. The 2-year cumulative incidence of graft failure following first HCT was 17% overall but 42% if mammalian target of rapamycin inhibitor(s) (mTORi) were used in the first year post-HCT, compared with 9% without mTORi. Similarly, 2-year cumulative incidence of unplanned donor cell infusion was overall 28%, but 65% in the context of mTORi receipt and 23% without. Phenotype reversal occurred in 96% of evaluable patients, of whom 17% had mixed chimerism. Vulnerability to renal complications continued post-HCT, adding new insights into potential nonimmunologic roles of phosphoinositide 3-kinase not correctable through HCT. Conclusions: Graft failure, graft instability, and poor graft function requiring unplanned donor cell infusion were major barriers to successful HCT. Post-HCT mTORi use may confer an advantage to residual host cells, promoting graft instability. Longer-term post-HCT follow-up of more patients is needed to elucidate the kinetics of immune reconstitution and donor chimerism, establish approaches that reduce graft instability, and assess the completeness of phenotype reversal over time.

Abstract
Epstein-Barr virus (EBV) load monitoring after allogeneic hematopoietic stem cell transplantation (HSCT) enables earlier detection of EBV replication and often serves as a trigger for preemptive therapies aimed at reducing EBV-related diseases. Our institutional strategy is to treat patients with clinical signs of EBV-related disease accompanied by a rising viral load, rather than to intervene based solely on viral load. This affords an opportunity to study the natural history of EBV replication and to assess whether our strategy reduces overtreatment without compromising outcomes. The objectives of the present study were to assess the natural history of untreated EBV replication in patients who underwent an alemtuzumab-based allogeneic HSCT and to examine whether our clinical strategy reduced overtreatment without compromising patient outcomes. In this retrospective single-center observational study of 515 consecutive patients (age ≥18 years) undergoing T cell-depleted allogeneic HSCT incorporating alemtuzumab, patients underwent surveillance monitoring for EBV by quantitative PCR in the peripheral blood at least weekly up to 100 days post-transplantation and longer if they remained on immunosuppressive therapy. The cumulative incidence of EBV detection and EBV-related disease were assessed. Among the 515 patients, 192 had EBV DNA detectable on ≥1 occasion, with a cumulative incidence of 35.8% (31.8% to 40.4%), although this remained below the limit of quantification in 93 patients. The median time to first detection was 89.5 days (range, 0 to 2254 days). The incidence was higher in recipients of sibling donor transplants (45.4% versus 30%; P = .00021) compared with recipients of unrelated donor transplants. Twenty patients developed EBV-related disease (cumulative incidence, 3.9%). Two patients had immunosuppression reduction alone, 18 received rituximab, and 5 required additional therapies. Five patients died from post-transplantation lymphoproliferative disorder, all of whom had received rituximab. The positive predictive value of EBV load for disease was higher in the unrelated donor cohort but remained <75% regardless of EBV threshold (57.1% to 72.7%). The cumulative incidence of EBV-related disease in our study (3.9%) is comparable to that reported in other studies incorporating alemtuzumab, and our clinical strategy reduced overtreatment in this patient population. PCR-based surveillance strategies have limitations, as reflected in the relatively low sensitivity of the assay coupled with the low positive predictive value, which may influence the potential choice of a threshold for preemptive intervention. We conclude that it remains unclear whether treatment based on a rising EBV viral load alone provides superior overall results to treatment based on the development of clinical signs of EBV-related disease in the context of a rising viral load.

Abstract
With recent advances in genetic sequencing and its widespread adoption for clinical diagnostics, the identification of a primary immunodeficiency (PID) as the underlying cause of diseases presenting to hematologists including refractory autoimmunity, cytopenias, immune dysregulation, and hematologic malignancy, is increasing, particularly in the adult population. Where the pathogenic genetic variants are restricted to the hematopoietic system, selected patients may benefit from allogeneic hematopoietic stem cell transplantation (allo-HSCT). Although it is generally accepted that early allo-HSCT (ie, in infancy or childhood) for PID is preferable, this is not always possible. The clinical phenotype of non-severe combined immune deficiency forms of PID can be very heterogeneous, in part because of the high number of genetic and functional defects affecting T, B, and natural killer cells, neutrophils, and/or antigen presentation. As a result, some patients have less severe disease manifestations in childhood and/or a later de novo presentation. For others, a delayed diagnosis, lack of a genetic diagnosis, or a previous lack of a suitable donor has precluded prior allo-HSCT. Specific issues which make transplantation for adult PID patients particularly challenging are discussed, including understanding the natural history of rare diseases and predicting outcome with conservative management alone; indications for and optimal timing of transplant; donor selection; conditioning regimens; and PID-specific transplant management. The role of gene therapy approaches as an alternative to allo-HSCT in high-risk monogenic PID is also discussed.

Abstract
Haematology patients receiving chemo- or immunotherapy are considered to be at greater risk of COVID-19-related morbidity and mortality. We aimed to identify risk factors for COVID-19 severity and assess outcomes in patients where COVID-19 complicated the treatment of their haematological disorder. A retrospective cohort study was conducted in 55 patients with haematological disorders and COVID-19, including 52 with malignancy, two with bone marrow failure and one immune-mediated thrombotic thrombocytopenic purpura (TTP). COVID-19 diagnosis coincided with a new diagnosis of a haematological malignancy in four patients. Among patients, 82% were on systemic anti-cancer therapy (SACT) at the time of COVID-19 diagnosis. Of hospitalised patients, 37% (19/51) died while all four outpatients recovered. Risk factors for severe disease or mortality were similar to those in other published cohorts. Raised C-reactive protein at diagnosis predicted an aggressive clinical course. The majority of patients recovered from COVID-19, despite receiving recent SACT. This suggests that SACT, where urgent, should be administered despite intercurrent COVID-19 infection, which should be managed according to standard pathways. Delay or modification of therapy should be considered on an individual basis. Long-term follow-up studies in larger patient cohorts are required to assess the efficacy of treatment strategies employed during the pandemic.

Abstract
Chronic granulomatous disease (CGD) is a rare inherited disorder of phagocytic cells1,2. We report the initial results of nine severely affected X-linked CGD (X-CGD) patients who received ex vivo autologous CD34+ hematopoietic stem and progenitor cell-based lentiviral gene therapy following myeloablative conditioning in first-in-human studies (trial registry nos. NCT02234934 and NCT01855685). The primary objectives were to assess the safety and evaluate the efficacy and stability of biochemical and functional reconstitution in the progeny of engrafted cells at 12 months. The secondary objectives included the evaluation of augmented immunity against bacterial and fungal infection, as well as assessment of hematopoietic stem cell transduction and engraftment. Two enrolled patients died within 3 months of treatment from pre-existing comorbidities. At 12 months, six of the seven surviving patients demonstrated stable vector copy numbers (0.4-1.8 copies per neutrophil) and the persistence of 16-46% oxidase-positive neutrophils. There was no molecular evidence of either clonal dysregulation or transgene silencing. Surviving patients have had no new CGD-related infections, and six have been able to discontinue CGD-related antibiotic prophylaxis. The primary objective was met in six of the nine patients at 12 months follow-up, suggesting that autologous gene therapy is a promising approach for CGD patients.

Abstract
TCR-gene-transfer is an efficient strategy to produce therapeutic T cells of defined antigen specificity. However, there are substantial variations in the cell surface expression levels of human TCRs, which can impair the function of engineered T cells. Here we demonstrate that substitutions of 3 amino acid residues in the framework of the TCR variable domains consistently increase the expression of human TCRs on the surface of engineered T cells.The modified TCRs mediate enhanced T cell proliferation, cytokine production and cytotoxicity, while reducing the peptide concentration required for triggering effector function up to 3000-fold. Adoptive transfer experiments in mice show that modified TCRs control tumor growth more efficiently than wild-type TCRs. Our data indicate that simple variable domain modifications at a distance from the antigen-binding loops lead to increased TCR expression and improved effector function. This finding provides a generic platform to optimize the efficacy of TCR gene therapy in humans.

Abstract
Immunotherapy constitutes an exciting and rapidly evolving field, and the demonstration that genetically modified T-cell receptors (TCRs) can be used to produce T-lymphocyte populations of desired specificity offers new opportunities for antigen-specific T-cell therapy. Overall, TCR-modified T cells have the ability to target a wide variety of self and non-self targets through the normal biology of a T cell. Although major histocompatibility complex (MHC)-restricted and dependent on co-receptors, genetically engineered TCRs still present a number of characteristics that ensure they are an important alternative strategy to chimeric antigen receptors (CARs), and high-affinity TCRs can now be successfully engineered with the potential to enhance therapeutic efficacy while minimizing adverse events. This review will focus on the main characteristics of TCR gene-modified cells, their potential clinical application and promise to the field of adoptive cell transfer (ACT), basic manufacturing procedures and characterization protocols and overall challenges that need to be overcome so that redirection of TCR specificity may be successfully translated into clinical practice, beyond early-phase clinical trials.

Abstract
Significant advances in hematopoietic transplantation over the past 20 years, have facilitated the safe transplantation of older adults with higher co-morbidities. In pediatric practice these advances have simultaneously improved outcomes for sicker children with complex, rare diseases including the primary immunodeficiencies, PID. With more widespread adoption of genetic sequencing, older patients with disease-causing mutations restricted to the hematopoietic system can be identified who may benefit from allogeneic hematopoietic stem cell transplantation (Allo-HSCT). Here we discuss the evidence for Allo-HSCT in adolescent and younger adults (AYAs) with PID.

Abstract
Purpose: Carcinoembryonic antigen (CEA) is a candidate target for cellular immunotherapy of pancreatic cancer. In this study, we have characterized the antigen-specific function of autologous cytotoxic T lymphocytes (CTL) specific for the HLA-A2-restricted peptide, pCEA691-699, isolated from the peripheral T-cell repertoire of pancreatic cancer patients and sought to determine if ex vivo PD-L1 and TIM-3 blockade could enhance CTL function.Experimental Design: CD8+ T-cell lines were generated from peripheral blood mononuclear cells of 18 HLA-A2+ patients with pancreatic cancer and from 15 healthy controls. In vitro peptide-specific responses were evaluated by flow cytometry after staining for intracellular cytokine production and carboxy fluorescein succinimydyl ester cytotoxicity assays using pancreatic cancer cell lines as targets.Results: Cytokine-secreting functional CEA691-specific CTL lines were successfully generated from 10 of 18 pancreatic cancer patients, with two CTL lines able to recognize and kill both CEA691 peptide-loaded T2 cells and CEA+ HLA-A2+ pancreatic cancer cell lines. In the presence of ex vivo PD-L1 blockade, functional CEA691-specific CD8+ T-cell responses, including IFNγ secretion and proliferation, were enhanced, and this effect was more pronounced on Ag-specific T cells isolated from tumor draining lymph nodes.Conclusions: These data demonstrate that CEA691-specific CTL can be readily expanded from the self-restricted T-cell repertoire of pancreatic cancer patients and that their function can be enhanced by PD-L1 blockade.

Abstract
Abstract
TCR gene transfer is used to redirect the antigen specificity of T lymphocytes towards known tumour antigens. TCR gene therapies in murine studies have shown promising results. However, in the clinic they often generate sub-optimal responses, when compared to treatments with tumour infiltrating lymphocytes. Previous work to improve TCR gene therapy has demonstrated that transferring additional CD3 genes increases TCR expression of both endogenous and introduced TCR in CD4+ and CD8+ T cells. In vivo experiments demonstrated that CD8+ T cells, transduced with TCR and additional CD3 were more effective in tumour protection than T cells transduced with the TCR alone. Whilst, CD4+ T cells transduced with TCR and additional CD3 initially showed improved tumour protection, lethal toxicity, unrelated to tumour burden, was later observed. To investigate the effects of CD3 overexpression, CD3 genes only (no TCR genes) were transferred into purified CD4+ and CD8+ T cells. Following adoptive transfer, CD3-enhanced CD4+ T cells survived for longer and were recovered in higher percentages in spleen, lymph nodes, bone marrow and liver, compared to CD3-enhanced CD8+ T cells and mock transduced CD4+ T cells. The same trend was also seen in competition experiments where mice received a 1:1 ratio of CD3-enhanced CD4+ T cells and mock-transduced CD4+ T cells. Interestingly, this was observed despite a twofold downregulation of TCR levels in the CD3-enhanced CD4+ T cells, compared to their pre-transfer TCR levels. Current experiments are aimed at dissecting the mechanisms responsible for, and the physiological implications of the observed TCR downregulation.

Abstract
Due to the lack of specificity for tumor antigens, allogeneic T-cell therapy is associated with graft-versus-host disease. Enhancing the anti-tumor specificity while reducing the graft-versus-host disease risk of allogeneic T cells has remained a research focus. In this study, we demonstrate that the introduction of 'dominant' T-cell receptors into primary murine T cells can suppress the expression of endogenous T-cell receptors in a large proportion of the gene-modified T cells. Adoptive transfer of allogeneic T cells expressing a 'dominant' T-cell receptor significantly reduced the graft-versus-host toxicity in recipient mice. Using two bone marrow transplant models, enhanced anti-tumor activity was observed in the presence of reduced graft-versus-host disease. However, although transfer of T-cell receptor gene-modified allogeneic T cells resulted in the elimination of antigen-positive tumor cells and improved the survival of treated mice, it was associated with accumulation of T cells expressing endogenous T-cell receptors and the development of delayed graft-versus-host disease. The in-vivo deletion of the engineered T cells, mediated by endogenous mouse mammary tumor virus MTV8 and MTV9, abolished graft-versus-host disease while retaining significant anti-tumor activity of adoptively transferred T cells. Together, this study shows that the in-vitro selection of allogeneic T cells expressing high levels of a 'dominant' T-cell receptor can lower acute graft-versus-host disease and enhance anti-tumor activity of adoptive cell therapy, while the in-vivo outgrowth of T cells expressing endogenous T-cell receptors remains a risk factor for the delayed onset of graft-versus-host disease.

Abstract
The precise role of autologous haematopoietic stem cell transplantation (ASCT) remains unclear in patients over 60 years of age. There is potential for increased procedural morbidity and mortality, and differences in disease biology that could impact outcomes. We performed a retrospective single-centre review of 81 elderly B-cell Non-Hodgkin Lymphoma patients undergoing ASCT. Five-year overall survival (OS) and progression-free survival (PFS) was 54·7% and 49·1% respectively. Non-relapse mortality (NRM) at 100 days and 1 year was 1·3% and 2·5%, suggesting no major excess compared to younger cohorts. OS and PFS were significantly worse in those over 65 years compared to those aged 60-64 (47·6% vs. 57·7%, P = 0·0437, and 27·6% vs. 57·7%, P = 0·0052 at 5 years). This resulted largely from an increased relapse risk (RR) (53·8% vs. 30·1%, P = 0·0511) rather than excess NRM, and age remained independently significant for PFS on multivariate analyses [Hazard ratio 2·56 (1·35-4·84, P = 0·0052) for PFS and 1·89 (0·99-3·61, P = 0·054) for OS]. Our data adds to the growing body of evidence demonstrating that ASCT can be an effective treatment strategy with an acceptable safety profile in selected elderly patients. Further evaluation of its overall benefit is warranted, however, in those over 65 years of age, as RR appears to be considerably higher.

Abstract
Viral and non-viral gene transfer technologies have been used to efficiently generate therapeutic T cells with desired cancer-specificity. Chimeric antigen receptors (CARs) redirect T cell specificity toward antibody-recognized antigens expressed on the surface of cancer cells, while T cell receptors (TCRs) extend the range of targets to include intracellular tumor antigens. CAR redirected T cells specific for the B cell differentiation antigen CD19 have shown dramatic efficacy in the treatment of B cell malignancies, while TCR-redirected T cells have shown benefits in patients suffering from solid cancer. In this review we will present strategies to optimize CAR and TCR function, and discuss the importance of target antigen selection to enhance tumor specificity, while reducing on-target and off-target toxicity.

Abstract
In this study, we generated human MHC Class I-restricted CD4+ T cells specific for Epstein-Barr virus (EBV) and cytomegalovirus (CMV), two herpesviridae associated with lymphoma, nasopharyngeal carcinoma and medulloblastoma, respectively. Retroviral transfer of virus-specific, HLA-A2-restricted TCR-coding genes generated CD4+ T cells that recognized HLA-A2/peptide multimers and produced cytokines when stimulated with MHC Class II-deficient cells presenting the relevant viral peptides in the context of HLA-A2. Peptide titration revealed that CD4+ T cells had a 10-fold lower avidity than CD8+ T cells expressing the same TCR. The impaired avidity of CD4+ T cells was corrected by simultaneously transferring TCR- and CD8-coding genes. The CD8 co-receptor did not alter the cytokine signature of CD4+ T cells, which remained distinct from that of CD8+ T cells. Using the xenogeneic NOD/SCID mouse model, we demonstrated that human CD4+ T cells expressing a specific TCR and CD8 can confer efficient protection against the growth of tumors expressing the EBV or CMV antigens recognized by the TCR. In summary, we describe a robust approach for generating therapeutic CD4+ T cells capable of providing MHC Class I-restricted immunity against MHC Class II-negative tumors in vivo.

Abstract
Wilms’ Tumour 1 (WT1) is a zinc finger transcription factor that is over-expressed in acute myeloid leukaemia (AML). Its restricted expression in normal tissues makes it a promising target for novel immunotherapies aiming to accentuate the cytotoxic T lymphocyte (CTL) response against AML. Here we report a phase I/II clinical trial of subcutaneous peptide vaccination with two separate HLA-A2-binding peptide epitopes derived from WT1, together with a pan-DR binding peptide epitope (PADRE), in Montanide adjuvant. Eight HLA-A2-positive patients with poor risk AML received five vaccination cycles at 3-weekly intervals. The three cohorts received 0·3, 0·6 and 1 mg of each peptide, respectively. In six patients, WT1-specific CTL responses were detected using enzyme-linked immunosorbent spot assays and pWT126/HLA-A*0201 tetramer staining, after ex vivo stimulation with the relevant WT1 peptides. However, re-stimulation of these WT1-specific T cells failed to elicit secondary expansion in all four patients tested, suggesting that the WT1-specific CD8+ T cells generated following vaccination may be functionally impaired. No correlation was observed between peptide dose, cellular immune response, reduction in WT1mRNA expression and clinical response. Larger studies are indicated to confirm these findings.

Abstract
The use of allogeneic haematopoietic stem cell transplantation (Allo-HSCT) is a standard treatment option for many patients with haematological malignancies. Historically, patients requiring intensive care unit (ICU) admission for transplant-related toxicities have fared extremely poorly, with high ICU mortality rates. Little is known about the impact of reduced intensity Allo-HSCT conditioning regimens in older patients on the ICU and subsequent long-term outcomes. A retrospective analysis of data collected from 164 consecutive Allo-HSCT recipients admitted to ICU for a total of 213 admissions, at a single centre over an 11·5-year study period was performed. Follow-up was recorded until 31 March 2011. Autologous HSCT recipients were excluded. In this study we report favourable ICU survival following Allo-HSCT and, for the first time, demonstrate significantly better survival for patients who underwent Allo-HSCT with reduced intensity conditioning compared to those treated with myeloablative conditioning regimens. In addition, we identified the need for ventilation (invasive or non-invasive) as an independently significant adverse factor affecting short-term ICU outcome. For patients surviving ICU admission, subsequent long-term overall survival was excellent; 61% and 51% at 1 and 5 years, respectively. Reduced intensity Allo-HSCT patients admitted to ICU with critical illness have improved survival compared to myeloablative Allo-HSCT recipients.

Abstract
The function of T lymphocytes as orchestrators and effectors of the adaptive immune response is directed by the specificity of their T cell receptors (TCRs). By transferring into T cells the genes encoding antigen-specific receptors, the functional activity of large populations of T cells can be redirected against defined targets including virally infected or cancer cells. The potential of therapeutic T cells to traffic to sites of disease, to expand and to persist after a single treatment remains a major advantage over the currently available immunotherapies that use monoclonal antibodies. Here we review recent progress in the field of TCR gene therapy, outlining challenges to its successful implementation and the strategies being used to overcome them. We detail strategies used in the optimization of affinity and surface expression of the introduced TCR, the choice of T cell subpopulations for gene transfer, and the promotion of persistence of gene-modified T cells in vivo. We review the safety concerns surrounding the use of gene-modified T cells in patients, discussing emerging solutions to these problems, and describe the increasingly positive results from the use of gene-modified T cells in recent clinical trials of adoptive cellular immunotherapy. The increasing sophistication of measures to ensure the safety of engineered T cells is accompanied by an increasing number of clinical trials: these will be essential to guide the effective translation of cellular immunotherapy from the laboratory to the bedside.

Abstract
Purpose Reduced-intensity conditioning has minimized nonrelapse-related mortality rates after allogeneic transplantation in patients with Hodgkin's lymphoma, and relapse has now become the major cause for treatment failure. We aimed to assess the impact of donor lymphocyte infusions (DLIs) on relapse incidence when administered for mixed chimerism and their utility as salvage therapy when given for relapse. Patients and Methods This study reports the outcomes of 76 consecutive patients with multiply relapsed or refractory Hodgkin's lymphoma who underwent allogeneic transplantation that incorporated in vivo T-cell depletion. Forty-two patients had related donors and 34 had unrelated donors. DLIs were administered in a dose-escalating fashion to 22 patients for mixed chimerism (median time of first dose, 9 months post-transplantation) and to 24 patients for relapse. Results Three-year donor lymphocyte–related mortality was 7%, relating mainly to the induction of graft-versus-host disease. Nineteen (86%) of 22 patients receiving donor lymphocytes for mixed chimerism converted to full donor status. Four-year relapse incidence was 5% in these 22 patients compared with 43% in patients who remained relapse free but full donor chimeras at 9 months post-transplantation (P = .0071). Nineteen (79%) of 24 patients receiving donor lymphocytes for relapse responded (14 complete responses, five partial responses). Four-year overall survival from relapse was 59% in recipients of donor lymphocytes, contributing to a 4-year overall survival from transplantation of 64% and a 4-year current progression-free survival of 59% in all 76 patients. Conclusion These data demonstrate the potential for allogeneic immunotherapy with donor lymphocytes both to reduce relapse risk and to induce durable antitumor responses in patients with Hodgkin's lymphoma after hematopoietic stem-cell transplantation that incorporates in vivo T-cell depletion.

Abstract
PURPOSE Follicular lymphoma (FL) is an indolent disorder that is treatable but considered incurable with chemotherapy alone. The curative potential of allogeneic transplantation using conventional myeloablative conditioning has been demonstrated, but this approach is precluded in the majority of patients with FL because of excessive toxicity. Thus, reduced-intensity conditioning regimens are being explored. PATIENTS AND METHODS This study reports the outcome of 82 consecutive patients with FL who underwent transplantation using fludarabine, melphalan, and alemtuzumab for in vivo T-cell depletion. Patients were heavily pretreated, having received a median of four lines of prior therapy, and 26% had experienced treatment failure with previous autologous transplantation. Median patient age was 45 years, and 52% of patients received stem cells from unrelated donors. RESULTS With a median follow-up time of 43 months, the nonrelapse mortality was 15% at 4 years (8% for sibling and 22% for unrelated donor transplantations), acute grade 2 or 3 graft-versus-host disease (GVHD) occurred in 13%, and the incidence of extensive chronic GVHD was only 18%. Although relapse risk was 26%, this was significantly reduced where mixed chimerism had been converted to full donor chimerism by the use of donor lymphocyte infusion (DLI; P = .03). In addition, 10 (77%) of 13 patients given DLI for relapse after transplantation experienced remission, with nine of these responses being sustained. Current progression-free survival at 4 years was 76% for the whole cohort (90% for those with sibling donors and 64% for those with unrelated donors). CONCLUSION The excellent long-term survival with associated low rates of GVHD and the frequency and durability of DLI responses make this an extremely encouraging strategy for the treatment and potential cure of FL.

Abstract
T-cell receptor (TCR) gene transfer is an attractive strategy to generate antigen-specific T-cells for adoptive immunotherapy of cancer and chronic viral infection. However, current TCR gene transfer protocols trigger T-cell differentiation into terminally differentiated effector cells, which likely have reduced ability to mediate disease protection in vivo. We have developed a lentiviral gene transfer strategy to generate TCR-transduced human T-cells without promoting T-cell differentiation. We found that a combination of interleukin-15 (IL15) and IL21 facilitated lentiviral TCR gene transfer into non-proliferating T-cells. The transduced T-cells showed redirection of antigen specificity and produced IL2, IFNgamma and TNFalpha in a peptide-dependent manner. A significantly higher proportion of the IL15/IL21-stimulated T-cells were multi-functional and able to simultaneously produce all three cytokines (P<0.01), compared with TCR-transduced T-cells generated by conventional anti-CD3 plus IL2 stimulation, which primarily secreted only one cytokine. Similarly, IL15/IL21 maintained high levels of CD62L and CD28 expression in transduced T-cells, whereas anti-CD3 plus IL2 accelerated the loss of CD62L/CD28 expression. The data demonstrate that the combination of lentiviral TCR gene transfer together with IL15/IL21 stimulation can efficiently redirect the antigen specificity of resting primary human T-cells and generate multi-functional T-cells.

Abstract
The T-cell receptor (TCR) is critical for T-cell lineage selection, antigen specificity, effector function and survival. Recently, TCR gene transfer has been developed as a reliable method to generate ex vivo large numbers of T cells of a given antigen-specificity and functional avidity. Such approaches have major applications for the adoptive cellular therapy of viral infectious diseases, virus-associated malignancies and cancer. TCR gene transfer utilizes retroviral or lentiviral constructs containing the gene sequences of the TCR-alpha and TCR-beta chains, which have been cloned from a clonal T-cell population of the desired antigen specificity. The TCR-encoding vector is then used to infect (transduce) primary T cells in vitro. To generate a transduced T cell with the desired functional specificity, the introduced TCR-alpha and TCR-beta chains must form a heterodimer and associate with the CD3 complex in order to be stably expressed at the T-cell surface. In order to optimize the function of TCR-transduced T cells, researchers in the field of TCR gene transfer have exploited many aspects of basic research in T-cell immunology relating to TCR structure, TCR-CD3 assembly, cell-surface TCR expression, TCR-peptide/major histocompatibility complex (MHC) affinity and TCR signalling. However, improving the introduction of exogenous TCRs into naturally occurring T cells has provided further insights into basic T-cell immunology. The aim of this review was to discuss the molecular immunology lessons learnt through therapeutic TCR transfer.

Abstract
Purpose The role of allogeneic transplantation with reduced-intensity conditioning in diffuse large B-cell lymphoma (DLBCL) is currently unclear, with relatively little published data. We report the outcome of reduced-intensity transplantation (RIT) in a cohort of 48 consecutive patients with relapsed/refractory DLBCL (30 patients with de novo disease and 18 patients with transformed follicular lymphoma) who underwent transplantation with an alemtuzumab-containing regimen, with a median follow-up of 52 months. Patients and Methods Patients had experienced treatment failure with a median of five lines of prior therapy, including autologous transplantation in 69%, and 17% of patients were chemotherapy refractory at transplantation. Median age was 46 years, and 38% of patients had matched/mismatched unrelated donors. Conditioning was with alemtuzumab, fludarabine, and melphalan, and additional graft-versus-host disease (GVHD) prophylaxis was with cyclosporine. Results All patients were successfully engrafted. Only 17% of patients developed grade 2 to 4 acute GVHD, with 13% experiencing extensive chronic GVHD. Four-year estimated nonrelapse mortality was 32%, and relapse risk was 33%. Twelve patients received donor lymphocyte infusions ± chemoimmunotherapy for relapse, and five patients obtained durable remissions, giving current progression-free survival (PFS) and overall survival (OS) rates at 4 years of 48% and 47%, respectively. Patients who had chemotherapy-sensitive disease before RIT had current PFS and OS rates at 4 years of 55% and 54%, respectively. Chemotherapy-refractory patients had a poor outcome. Conclusion The encouraging survival rates with extended follow-up suggest a role for RIT in chemotherapy-sensitive relapsed DLBCL, even in patients who have previously experienced treatment failure with autologous transplantation. Future studies will be required to determine whether any subset of patients with relapsed DLBCL should be considered for RIT versus autologous transplantation.

Abstract
This study compares outcome of reduced-intensity conditioned transplant (RIT) with outcome of conventional non-transplant therapy in patients with Hodgkin's lymphoma relapsing following autograft. There were 72 patients in two groups who had relapsed, and received salvage therapy with chemotherapy+/-radiotherapy. One group (n=38) then underwent alemtuzumab-containing RIT. The second group-historical controls (n=34), relapsing before the advent of RIT-had no further high-dose therapy. This group was required to respond to salvage therapy and live for over 12 months post-relapse, demonstrating potential eligibility for RIT, had this been available. Overall survival (OS) from diagnosis was superior following RIT (48% at 10 years versus 15%; P=0.0014), as was survival from autograft (65% at 5 years versus 15%; P< or =0.0001). For the RIT group, OS at 5 years from allograft was 51%, and in chemoresponsive patients was 58%, with current progression-free survival of 42%. Responses were seen in 8 of 15 patients receiving donor lymphocyte infusions (DLI) for relapse/progression, with durable remission in five patients at median follow-up from DLI of 45 months (28-55). These data demonstrate the potential efficacy of RIT in heavily pre-treated patients whose outlook with conventional therapy is dismal, and provide evidence of a clinically relevant graft-versus-lymphoma effect.

Abstract
Adoptive transfer of antigen-specific T lymphocytes is an effective form of immunotherapy for persistent virus infections and cancer. A major limitation of adoptive therapy is the inability to isolate antigen-specific T lymphocytes reproducibly. The demonstration that cloned T-cell receptor (TCR) genes can be used to produce T lymphocyte populations of desired specificity offers new opportunities for antigen-specific T-cell therapy. TCR gene-modified lymphocytes display antigen-specific function in vitro, and were shown to protect against virus infection and tumor growth in animal models. A recent trial in humans demonstrated that TCR gene-modified T cells persisted in all and reduced melanoma burden in 2/15 patients. In future trials, it may be possible to use TCR gene transfer to equip helper and cytotoxic T cells with new antigen-specificity, allowing both T-cell subsets to cooperate in achieving improved clinical responses. Sequence modifications of TCR genes are being explored to enhance TCR surface expression, while minimizing the risk of pairing between introduced and endogenous TCR chains. Current T-cell transduction protocols that trigger T-cell differentiation need to be modified to generate "undifferentiated" T cells, which, upon adoptive transfer, display improved in vivo expansion and survival. Both, expression of only the introduced TCR chains and the production of naïve T cells may be possible in the future by TCR gene transfer into stem cells.

Abstract
BACKGROUND In patients with multiply relapsed Hodgkin's lymphoma allogeneic stem-cell transplantation has been limited by prohibitive non-relapse-related mortality rates and by a lack of definitive evidence for a therapeutic graft-versus-tumour effect. Therefore, we aimed to assess the graft-versus-tumour effect of reduced-intensity allogeneic transplantation. METHODS We undertook reduced-intensity transplantation in 49 patients with multiply relapsed Hodgkin's lymphoma, 44 (90%) of whom had progression of disease after previous autologous transplantation (median age 32 years [range 18-51], number of previous treatment courses was five [range 3-8], and time from diagnosis 4.8 years [range 0.6-4.8]). 31 patients had HLA matched donors who were related and 18 had donors who were unrelated. Median follow-up was 967 days (range 102-2232). The primary endpoints were engraftment, toxic effects, non-relapse-related mortality, incidence of graft-versus-host disease (GVHD), and the toxic effects of adjuvant donor-lymphocyte infusion. FINDINGS All patients engrafted. Eight of 49 (16%) had grade II-IV acute GVHD and seven (14%) had chronic GVHD before donor-lymphocyte infusion. 16 (33%) patients received donor-lymphocyte infusion from 3 months after transplantation for residual disease or progression. Six (38%) of the 16 developed grade II-IV acute GVHD and five developed chronic GVHD. Nine (56%) showed disease responses after infusion (eight complete, one partial). Non-relapse-related mortality was 16.3% at 730 days (7.2% for patients who had related donors vs 34.1% for those with unrelated donors, p=0.0206). Projected 4 year overall and progression-free survival were 55.7% and 39.0%, respectively (62.0% and 41.5% for related donors). INTERPRETATION These data show the potential for durable responses in patients who have previously had substantial treatment for Hodgkin's lymphoma. The low non-relapse-related mortality suggests the procedure could be undertaken earlier in the course of the disease.

Abstract
Adoptive transfer of antigen-specific CD4(+) and CD8(+) T cells is one of the most efficient forms of cancer immunotherapy. However, the isolation of antigen-specific CD4(+) T cells is limited because only few tumor-associated helper epitopes are identified. Here, we used T cell antigen receptor gene transfer to target CD4(+) T cells against an MHC class I-presented epitope of a model tumor antigen. IFN-gamma-producing CD4(+) T cells were unable to expand in vivo and to provide help for tumor rejection. In contrast, CD4(+) T cells producing high levels of IL-2 expanded in vivo, provided help for cytotoxic T lymphocyte-mediated tumor rejection, and developed T cell memory. The data demonstrate in vivo synergy between T cell antigen receptor-transduced CD4(+) and CD8(+) T cells specific for the same epitope resulting in long-term tumor protection.

Abstract
Treatment options for patients with low-grade non-Hodgkin's lymphomas (NHLs) are many and varied. For those with relapsed or refractory disease, outcome following conventional and high dose chemotherapy remains poor. Conventional allogeneic stem cell transplantation has been shown to have curative potential in the management of indolent NHL, but due to the high transplant-related mortality improvement in overall survival has been insignificant. Recent reports have confirmed the feasibility of reduced intensity conditioning allogeneic stem cell transplantation as a treatment option for many older patients with NHL. Here we will discuss the rationale behind reduced intensity transplantation (RIT), the development of the regimens currently adopted in clinical practice and review the published literature on RIT for indolent NHL.

Abstract
Fluorine-18 fluorodeoxyglucose positron emission tomography ((18)F-FDG PET) provides valuable prognostic information in the management of lymphoma patients. However, the utility of (18)F-FDG PET following allografting is unclear. We analysed the use of (18)F-FDG PET after allogeneic reduced-intensity transplantation (RIT) performed in our institution. Between June 1998 and January 2002, 55 patients underwent RIT for either Hodgkin or non-Hodgkin lymphoma. At least one (18)F-FDG PET scan was performed during the post-transplant period (median five studies) in 15 (27.2%) of these 55 patients. PET scans were performed after re-staging computed tomography (CT) and were categorised depending on (18)F-FDG uptake. The first PET scan was informative in 11 of 15 patients (73%) and influenced the administration of donor lymphocyte infusions (DLI) in nine: leading to earlier DLI administration in two patients, earlier dose escalation in one, withholding of DLI administration in five and dose reduction in one. In addition, subsequent monitoring with (18)F-FDG PET scans documented a graft-versus-lymphoma effect in five patients (median post-DLI follow-up 33 months, range 13-36 months). These preliminary data suggest that (18)F-FDG PET has a role in guiding DLI administration and monitoring the immunotherapeutic effect in patients after allogeneic transplantation. This retrospective pilot study forms the basis for a prospective study to clarify the utility of (18)F-FDG PET/CT in these patients.

Abstract
Data on the application of donor lymphocyte infusions (DLIs) following reduced-intensity transplantation (RIT) remain limited. Persistence of host antigen-presenting cells might increase the efficacy or toxicity of cellular immunotherapies. We report the results of dose-escalating DLIs in 46 patients undergoing RIT, who received a total of 109 infusions to treat mixed chimerism or residual or progressive disease. Diagnoses were myeloma (n = 19), Hodgkin lymphoma (n = 13), non-Hodgkin lymphoma (n = 10), and other (n = 4). Thirty-two had an HLA-matched family donor and 14 an unrelated donor. Grades II to IV graft-versus-host disease (GVHD) occurred in 5 sibling and 7 unrelated donor recipients. GVHD was more common (P =.002), occurred at lower T-cell doses, and was more severe in the unrelated donor cohort. Conversion from mixed to multilineage full donor chimerism occurred in 30 of 35 evaluable patients. Presence of mixed chimerism in the granulocyte lineage at the time of DLI did not predict for chimerism response or GVHD. Disease responses occurred in 63% of patients with myeloma and 70% of those with Hodgkin lymphoma and were not predicted by changes in chimerism. These data support the presence of clinically relevant graft-versus-Hodgkin activity and indicate that DLI may be associated with a significantly increased toxicity in unrelated compared to sibling donor transplant recipients receiving identical treatment protocols.
