Abstract
The American Society for Transplantation and Cellular Therapy (ASTCT) published its first white paper on indications for autologous and allogeneic hematopoietic cell transplantation (HCT) in 2015. It was identified at the time that periodic updates of indications would be required to stay abreast with state of the art and emerging indications and therapy. In recent years the field has not only seen an improvement in transplantation technology, thus widening the therapeutic scope of HCT, but additionally a whole new treatment strategy using modified immune effector cells, including chimeric antigen receptor T cells and engineered T-cell receptors, has emerged. The guidelines review committee of the ASTCT deemed it optimal to update the ASTCT recommendations for indications for HCT to include new data and to incorporate indications for immune effector cell therapy (IECT) where appropriate. The guidelines committee established a multiple stakeholder task force consisting of transplant experts, payer representatives, and a patient advocate to provide guidance on indications for HCT and IECT. This article presents the updated recommendations from the ASTCT on indications for HCT and IECT. Indications for HCT/IECT were categorized as (1) Standard of care, where indication is well defined and supported by evidence; (2) Standard of care, clinical evidence available, where large clinical trials and observational studies are not available but have been shown to be effective therapy; (3) Standard of care, rare indication, for rare diseases where demonstrated effectiveness exists but large clinical trials and observational studies are not feasible; (4) Developmental, for diseases where preclinical and/or early-phase clinical studies show HCT/IECT to be a promising treatment option; and (5) Not generally recommended, where available evidence does not support the routine use of HCT/IECT. The ASTCT will continue to periodically review these guidelines and update them as new evidence becomes available.

Abstract
BACKGROUND The standard for selecting unrelated umbilical cord blood units for transplantation for non-malignant diseases relies on antigen-level (lower resolution) HLA typing for HLA-A and HLA-B, and allele-level for HLA-DRB1. We aimed to study the effects of allele-level matching at a higher resolution-HLA-A, HLA-B, HLA-C, and HLA-DRB1, which is the standard used for adult unrelated volunteer donor transplantation for non-malignant diseases-for umbilical cord blood transplantation. METHODS We retrospectively studied 1199 paediatric donor-recipient pairs with allele-level HLA matching who received a single unit umbilical cord blood transplantation for non-malignant diseases reported to the Center for International Blood and Marrow Transplant Research or Eurocord and European Group for Blood and Marrow Transplant. Transplantations occurred between Jan 1, 2000, and Dec 31, 2012. The primary outcome was overall survival. The effect of HLA matching on survival was studied using a Cox regression model. FINDINGS Compared with HLA-matched transplantations, mortality was higher with transplantations mismatched at two (hazard ratio [HR] 1·55, 95% CI 1·08-2·21, p=0·018), three (2·04, 1·44-2·89, p=0·0001), and four or more alleles (3·15, 2·16-4·58, p<0·0001). There were no significant differences in mortality between transplantations that were matched and mismatched at one allele (HR 1·18, 95% CI 0·80-1·72, p=0·39). Other factors associated with higher mortality included recipient cytomegalovirus seropositivity (HR 1·40, 95% CI 1·13-1·74, p=0·0020), reduced intensity compared with myeloablative conditioning regimens (HR 1·36, 1·10-1·68, p=0·0041), transplantation of units with total nucleated cell dose of more than 21 × 107 cells per kg compared with 21 × 107 cells per kg or less (HR 1·47, 1·11-1·95, p=0·0076), and transplantations done in 2000-05 compared with those done in 2006-12 (HR 1·64, 1·31-2·04, p<0·0001). The 5-year overall survival adjusted for recipient cytomegalovirus serostatus, conditioning regimen intensity, total nucleated cell dose, and transplantation period was 79% (95% CI 74-85) after HLA matched, 76% (71-81) after one allele mismatched, 70% (65-75) after two alleles mismatched, 62% (57-68) after three alleles mismatched, and 49% (41-57) after four or more alleles mismatched transplantations. Graft failure was the predominant cause of mortality. INTERPRETATION These data support a change from current practice in that selection of unrelated umbilical cord blood units for transplantation for non-malignant diseases should consider allele-level HLA matching at HLA-A, HLA-B, HLA-C, and HLA-DRB1.

Abstract
Approximately 20,000 hematopoietic cell transplantation (HCT) procedures are performed in the United States annually. With advances in transplantation technology and supportive care practices, HCT has become safer, and patient survival continues to improve over time. Indications for HCT continue to evolve as research refines the role for HCT in established indications and identifies emerging indications where HCT may be beneficial. The American Society for Blood and Marrow Transplantation (ASBMT) established a multiple-stakeholder task force consisting of transplant experts, payer representatives, and a patient advocate to provide guidance on "routine" indications for HCT. This white paper presents the recommendations from the task force. Indications for HCT were categorized as follows: (1) Standard of care, where indication for HCT is well defined and supported by evidence; (2) Standard of care, clinical evidence available, where large clinical trials and observational studies are not available but HCT has been shown to be effective therapy; (3) Standard of care, rare indication, for rare diseases where HCT has demonstrated effectiveness but large clinical trials and observational studies are not feasible; (4) Developmental, for diseases where preclinical and/or early phase clinical studies show HCT to be a promising treatment option; and (5) Not generally recommended, where available evidence does not support the routine use of HCT. The ASBMT will periodically review these guidelines and will update them as new evidence becomes available.

Abstract
Patients with Langerhans cell histiocytosis (LCH) refractory to conventional chemotherapy have a poor outcome. There are currently two promising treatment strategies for high-risk patients: the first involves the combination of 2-chlorodeoxyadenosine and cytarabine; the other approach is allogeneic haematopoietic stem cell transplantation (HSCT). Here we evaluated 87 patients with high-risk LCH who were transplanted between 1990 and 2013. Prior to the year 2000, most patients underwent HSCT following myeloablative conditioning (MAC): only 5 of 20 patients (25%) survived with a high rate (55%) of transplant-related mortality (TRM). After the year 2000 an increasing number of patients underwent HSCT with reduced intensity conditioning (RIC): 49/67 (73%) patients survived, however, the improved survival was not overtly achieved by the introduction of RIC regimens with similar 3-year probability of survival after MAC (77%) and RIC transplantation (71%). There was no significant difference in TRM by conditioning regimen intensity but relapse rates were higher after RIC compared to MAC regimens (28% vs. 8%, P = 0·02), although most patients relapsing after RIC transplantation could be salvaged with further chemotherapy. HSCT may be a curative approach in 3 out of 4 patients with high risk LCH refractory to chemotherapy: the optimal choice of HSCT conditioning remains uncertain.

Abstract
Defective V(D)J recombination and DNA double-strand break (DSB) repair severely impair the development of T-lymphocytes and B-lymphocytes. Most patients manifest a severe combined immunodeficiency during infancy. We report 2 siblings with combined immunodeficiency (CID) and immunodysregulation caused by compound heterozygous Artemis mutations, including an exon 1-3 deletion generating a null allele, and a missense change (p.T71P). Skin fibroblasts demonstrated normal DSB repair by gamma-H2AX analysis, supporting the predicted hypomorphic nature of the p.T71P allele. In addition to these two patients, 12 patients with Artemis-deficient CID were previously reported. All had significant morbidities including recurrent infections, autoimmunity, EBV-associated lymphoma, and carcinoma despite having hypomorphic mutants with residual Artemis expression, V(D)J recombination or DSB repair capacity. Nine patients underwent stem cell transplant and six survived, while four patients who did not receive transplant died. The progressive nature of immunodeficiency and genomic instability accounts for poor survival, and early HSCT should be considered.

Abstract
This study presents four patients who underwent bone marrow transplantation and subsequently developed pleuroparenchymal fibroelastosis, hitherto reported as an idiopathic condition. All presented clinically with pneumothorax and subpleural fibrosis on high-resolution computed tomography. In addition to the expected obliterative bronchiolitis, histopathology showed coexistent subpleural changes, and the relationship of pathology in multiple anatomic compartments in post bone marrow transplantation pulmonary disease is discussed.

Abstract
BACKGROUND Stem-cell transplantation can cure primary immunodeficiencies. However, in patients with pre-existing organ toxicity, patients younger than 1 year, and those with DNA or telomere repair disorders, chemotherapy-based conditioning is poorly tolerated and results in major morbidity and mortality. We tested a novel antibody-based minimal-intensity conditioning (MIC) regimen to assess whether this approach allowed curative donor stem-cell engraftment without non-haemopoietic toxicity. METHODS 16 high-risk patients underwent stem-cell transplantation for primary immunodeficiencies with an MIC regimen consisting of two rat anti-CD45 monoclonal antibodies YTH 24.5 and YTH 54.12 for myelosuppression, and alemtuzumab (anti-CD52) and fludarabine, and low dose cyclophosphamide for immunosuppression. Donors were matched siblings (n=5), and matched (9) and mismatched (2) unrelated donors. FINDINGS Antibody-based conditioning was well tolerated, with only two cases of grade 3 and no grade 4 toxicity. Rates of clinically significant acute (n=6, 36%) and chronic graft-versus-host disease (GVHD) (n=5, 31%) were acceptable. 15 of 16 patients (94%) engrafted, of whom 11 (69%) achieved full or high-level mixed chimerism in both lymphoid and myeloid lineages, and three achieved engraftment in the T-lymphoid lineage only. One patient needed retransplantation. At a median of 40 months post-transplant, 13 of 16 patients (81%) in this high-risk cohort were alive and cured from their underlying disease. INTERPRETATION Monoclonal antibody-based conditioning seems well tolerated and can achieve curative engraftment even in patients with severe organ toxicity or DNA repair defects, or both. This novel approach represents a shift from the paradigm that intensive chemotherapy or radiotherapy, or both, is needed for donor stem-cell engraftment. This antibody-based conditioning regimen may reduce toxicity and late effects and enable SCT in virtually any primary immunodeficiency patient with a matched donor. FUNDING None.

Abstract
We reviewed outcomes after allogeneic hematopoietic cell transplantation (HCT) in 35 children with Chediak-Higashi syndrome (CHS). Twenty-two patients had a history of the life-threatening accelerated phase of CHS before HCT and 11 were in accelerated phase at transplantation. Thirteen patients received their allograft from an human leukocyte antigen (HLA)-matched sibling, 10 from an alternative related donor and 12 from an unrelated donor. Eleven recipients of HLA-matched sibling donor, three recipients of alternative related donor and eight recipients of unrelated donor HCT are alive. With a median follow-up of 6.5 years, the 5-year probability of overall survival is 62%. Mortality was highest in those with accelerated phase disease at transplantation and after alternative related donor HCT. Only four of 11 patients with active disease at transplantation are alive. Seven recipients of alternative related donor HCT had active disease at transplantation and this may have influenced the poor outcome in this group. Although numbers are limited, HCT appears to be effective therapy for correcting and preventing hematologic and immunologic complications of CHS, and an unrelated donor may be a suitable alternative for patients without an HLA-matched sibling. Early referral and transplantation in remission after accelerated phase disease may improve disease-free survival.

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
Gene therapy is a promising treatment option for monogenic diseases, but success has been seen in only a handful of studies thus far. We now document successful reconstitution of immune function in a child with the adenosine deaminase (ADA)-deficient form of severe combined immunodeficiency (SCID) following hematopoietic stem cell (HSC) gene therapy. An ADA-SCID child who showed a poor response to PEG-ADA enzyme replacement was enrolled into the clinical study. Following cessation of enzyme replacement therapy, autologous CD34(+) HSCs were transduced with an ADA-expressing gammaretroviral vector. Gene-modified cells were reinfused following one dose of preconditioning chemotherapy. Two years after the procedure, immunological and biochemical correction has been maintained with progressive increase in lymphocyte numbers, reinitiation of thymopoiesis, and systemic detoxification of ADA metabolites. Sustained vector marking with detection of polyclonal vector integration sites in multiple cell lineages and detection of ADA activity in red blood cells suggests transduction of early hematopoietic progenitors. No serious side effects were seen either as a result of the conditioning procedure or due to retroviral insertion. Gene therapy is an effective treatment option for the treatment of ADA-SCID.

Abstract
The optimal approach to stem cell transplantation in children with immunodeficiency who lack a matched family donor is controversial. Unrelated donor stem cell transplantation gives equivalent outcome to mismatched family donor stem cell transplantation in severe combined immunodeficiency, whereas unrelated donors may be preferable in non–severe combined immunodeficiency children. However, unrelated donor stem cell transplantation with conventional conditioning regimens has been associated with significant treatment-related toxicity, particularly in non–severe combined immunodeficiency patients with preexisting organ dysfunction. We report the outcome of a series of 33 consecutive unrelated donor transplantations performed at our center in children with primary immunodeficiency using a reduced-intensity conditioning regimen between 1998 and 2001. We have compared these outcomes with a retrospective control cohort of 19 patients who underwent transplantation with myeloablative conditioning between 1994 and 1998. All children in both groups had primary engraftment. There was no statistical difference in the speed of immune reconstitution or incidence of graft-versus-host disease between the 2 groups. Overall survival was significantly better in the reduced-intensity conditioning group: 31 (94%) of 33 patients survived, compared with 10 (53%) of 19 in the myeloablative conditioning group (P = .014). We conclude that the reduced-intensity conditioning regimen results in improved survival and reduced transplantation-related mortality compared with myeloablative conditioning in high-risk patients undergoing unrelated donor transplantation.

Abstract
BACKGROUND Invasive aspergillosis is an uncommon but life-threatening event in the immunocompromised child. Attempts at fungal isolation are often unrewarding and a high index of radiological suspicion is essential in the early diagnosis of infected children. OBJECTIVE To document the radiological spectrum of disease in invasive aspergillosis in the paediatric population. MATERIALS AND METHODS A retrospective review of the imaging performed in 27 consecutive patients (age 7 months to 18 years) with documented invasive Aspergillosis encountered over a 10-year period at a single institution. RESULTS Radiographic findings of pulmonary disease (20 patients) included segmental and multilobar consolidation, perihilar infiltrates, multiple small nodules, peripheral nodular masses and pleural effusions. No cavitating lesions were seen on CXR. Small cavitating nodules were present on CT in two of eight children. Chest wall disease was particularly associated with underlying chronic granulomatous disease. Disseminated disease manifested as osteomyelitis (n=5), cerebral (n=3), oesophageal (n=1), hepatic (n=2), renal (n=2) and cutaneous (n=5) involvement. Imaging findings are discussed. Twelve patients (44%) subsequently died from Aspergillus-related complications. CONCLUSIONS Invasive aspergillosis presents with a wide variety of radiographic findings involving multiple organ systems. Respiratory findings are varied but often non-specific, and a high index of suspicion is necessary in immunocompromised patients. In contrast to adult disease, the incidence of cavitation of pulmonary lesions appears low.

Abstract
PURPOSE This study sought to determine whether the identification of minimal pulmonary metastatic disease by chest computed tomography (CT) performed at diagnosis in patients with Wilms' tumor and normal chest x-rays (CXR) could predict a subgroup of children at increased risk of pulmonary relapse. PATIENTS AND METHODS A retrospective analysis was carried out of the records of 449 children entered onto the United Kingdom Childrens' Cancer Study Group Second Wilms' Tumor Study between July 1986 and September 1991. The imaging protocol did not stipulate chest CT at diagnosis, but 141 children who had normal frontal and lateral CXRs and a chest CT scan performed at diagnosis were eligible for analysis. After surgery, children with stage I Wilms' tumor received single-agent chemotherapy (vincristine), whereas children with stages II, III, and bilateral Wilms' tumor received combination chemotherapy. Most children with stage III tumors were also treated with abdominal radiotherapy (20 Gy). RESULTS In 31 patients (22%), pulmonary nodules were visible on chest CT; eight experienced relapse, four (15%) in the lungs. When only stage I patients were analyzed, there was a significant difference between the pulmonary relapse rate of 43% (three of seven) in the CT-positive group and 10% (five of 48) in the CT-negative group (P =.02). Four of eight patients with stage I disease with pulmonary relapse died. CONCLUSION CT seemed to identify a subgroup of stage I patients who were at increased risk of pulmonary relapse. These children had received only single-agent chemotherapy. A prospective randomized trial is needed to clarify whether these children would benefit from combination chemotherapy.

Abstract
Mutations of the Janus kinase 3 (JAK3) have been previously described to cause an autosomal recessive variant of severe combined immunodeficiency (SCID) usually characterized by the near absence of T and NK cells, but preserved numbers of B lymphocytes (T-B+SCID). We now report a family whose JAK3 mutations are associated with the persistence of circulating T cells, resulting in previously undescribed clinical presentations, ranging from a nearly unaffected 18-year-old subject to an 8-year-old sibling with a severe lymphoproliferative disorder. Both siblings were found to be compound heterozygotes for the same deleterious JAK3 mutations: an A96G initiation start site mutation, resulting in a dysfunctional, truncated protein product and a G2775(+3)C mutation in the splice donor site sequence of intron 18, resulting in a splicing defect and a predicted premature stop. These mutations were compatible with minimal amounts of functional JAK3 expression, leading to defective cytokine-dependent signaling. Activated T cells in these patients failed to express Fas ligand (FasL) in response to IL-2, which may explain the accumulation of T cells with an activated phenotype and a skewed T cell receptor (TcR) Vbeta family distribution. We speculate that residual JAK3 activity accounted for the maturation of thymocytes, but was insufficient to sustain IL-2-mediated homeostasis of peripheral T cells via Fas/FasL interactions. These data demonstrate that the clinical spectrum of JAK3 deficiency is quite broad and includes immunodeficient patients with accumulation of activated T cells, and indicate an essential role for JAK3 in the homeostasis of peripheral T cells in humans.

Abstract
This paper details a UK consensus conference held in London in April 2000 to establish guidelines for the use of cyclosporin A for atopic dermatitis in children. It should be reserved for the severest refractory atopic dermatitis. In view of its potential toxicity, careful monitoring is mandatory, in particular blood pressure and renal function.

Abstract
The increasing success of human leucocyte antigen (HLA)-matched sibling donor (MSD) transplants and combination immunosuppressive treatments have dramatically improved the prognosis of severe aplastic anaemia (SAA) in children and young adults. For patients who lack a MSD there is a significant minority who fail immunosuppressive therapy or suffer from a severe constitutional aplastic anaemia in which immunosuppression would be ineffective. Alternative donor bone marrow transplantation (AD-BMT) has only had limited success in this context. We report the successful outcome of AD-BMT in eight consecutive patients aged 7 months to 15 years, six of whom had acquired aplastic anaemia who had previously failed to respond to immunosuppression, and two of whom had a severe (non-Fanconi) constitutional aplastic anaemia. All eight patients had received multiple red cell and platelet transfusions. We used a new combination of agents for pretransplant conditioning aiming to maximize immunosuppression and minimize toxicity, consisting of Campath-1G or -1H, cyclophosphamide and low-dose total body irradiation (LD TBI) or fludarabine. Toxicity was minimal and all eight children are alive, well and free of disease at a median follow-up of 32 months. We suggest that this approach could facilitate the successful treatment of children with SAA in whom immunosuppressive therapy has failed or is not appropriate.

Abstract
The clinical course of 10 children who have been diagnosed with major histocompatibility complex (MHC) class II deficiency (bare lymphocyte syndrome) in the UK over the past eight years is described. They have had a generally poor prognosis, with only two of the 10 still alive despite eight attempts at bone marrow transplantation in six patients. Overwhelming viral infection was the predominant cause of death. Alternative transplant strategies or novel therapies are required for these patients.

Abstract
This was an open study of oral antifungal prophylaxis in 103 neutropenic children aged 0-14 (median 5) years. Most (90%) were undergoing transplantation for haematological conditions (77% allogeneic BMT, 7% autologous BMT, 6% PBSC transplants and 10% chemotherapy alone). They received 5.0 mg/kg itraconazole/day (in 10 mg/ml cyclodextrin solution). Where possible, prophylaxis was started at least 7 days before the onset of neutropenia and continued until neutrophil recovery. Of the 103 who entered the study, 47 completed the course of prophylaxis, 27 withdrew because of poor compliance, 19 because of adverse events and 10 for other reasons. Two patients died during the study and another five died within the subsequent 30 days. No proven systemic fungal infections occurred, but 26 patients received i.v. amphotericin for antibiotic-unresponsive pyrexia. One patient received amphotericin for mycologically confirmed oesophageal candidosis. Three patients developed suspected oral candidosis but none was mycologically proven and no treatment was given. Serious adverse events (other than death) occurred in 21 patients, including convulsions (7), suspected drug interactions (6), abdominal pain (4) and constipation (4). The most common adverse events considered definitely or possibly related to itraconazole were vomiting (12), abnormal liver function (5) and abdominal pain (3). Tolerability of study medication at end-point was rated as good (55%), moderate (11%), poor (17%) or unacceptable (17%). Some patients had poor oral intakes due to mucositis. No unexpected problems of safety or tolerability were encountered. We conclude that itraconazole oral solution may be used as antifungal prophylaxis for neutropenic children.

Abstract
Only 30% of children have a matched family donor (MFD). Alternative donors can be found from volunteer unrelated donor (UD) panels, and almost every child has a haploidentical parental donor (Haplo). The outcome of alternative donor BMT has previously been inferior due to increased graft rejection and GVHD. The recent outcome of 121 consecutive children undergoing MFD, UD, and Haplo BMT between 1994 and 1997 was analysed. [table in text] Preparative regimens for MFD/UD/Haplo BMT respectively included TBI in 30%/36%/11%, chemotherapy only in 59%/64%/89%, Campath 1G or none n 14%/ 0%/0%. The balance of GVHD and rejection was addressed by T-cell depletion (Campath 1M) in 2/71 MFD BMTs, T-cell depletion with addback of 5 x 10(4) T cells/kg on day zero in 33/41 UD BMTs, and T cell depletion of purified mobilised peripheral blood CD34+ cells and bone marrow in 9/9 Haplo BMTs. Stable engraftment was achieved in 68/71, and 35/41 (one patient after 2nd BMT) and 7/9 MFD, UD, and Haplo BMTs respectively. Median follow up, survival, disease free survival and, death rates for MFD/UD/Haplo BMT were 12/12/12 months, 74%/77%/78%, 69%/67%/67%, and 27%/23%/23% respectively. Within a wide range of paediatric diseases the outcome of alternative donor BMT now parallels that of MFD BMT.

Abstract
Agranulocytosis developed in a 20-year-old Greek patient with beta-thalassaemia major, 11 weeks after commencing chelation with the oral iron chelator 1,2-dimethyl-3-hydroxypyrid-4-one (L1) and 6 weeks after receiving the drug at a total daily dose of 105 mg/kg. The patient presented with generalised weakness, low-grade fever and sore throat. The total white cell count was 2.0 x 10(9)/l with 0.1 x 10(9)/l neutrophils. The patient was admitted to hospital and successfully treated with intravenous broad-spectrum antibiotics. Neutrophil count recovered 7 weeks later. A number of immunological tests were performed in an attempt to elucidate the cause of agranulocytosis. These investigations gave inconclusive evidence for the presence of a weak IgM antibody to myeloid cells exposed to L1 in this patient. Further studies are required, however, to evaluate the mechanism in any other patient who develops agranulocytosis in association with L1 therapy.

Abstract
An incidence of drug-induced neutropenia of 2.5% has been found in the first 1000 patients to be treated with clozapine in the UK. The majority of affected patients experienced mild neutropenia (n = 22) with only 3 patients developing agranulocytosis. Data collected from these 25 patients suggest that the mechanism of neutropenia may be multifactorial. Laboratory investigation using liquid culture systems and immunofluorocytometry has identified clozapine and its major metabolite N-desmethyl clozapine as exhibiting toxic effects against myeloid maturation and myeloid mitotic compartments, respectively. Increased susceptibility to the toxic effects of clozapine was shown in 1 patient who had previously developed clozapine-associated neutropenia. No clinical or laboratory evidence of drug-induced antineutrophil or antimyeloid precursor antibodies was found.

Abstract
Psychotropic drugs frequently cause agranulocytosis. It is therefore important that patients on these drugs who develop symptoms or signs of infection should have a full blood count performed, and if the neutrophil count is reduced, prompt withdrawal of the drug and, if necessary, immediate supportive care should be given to reduce the incidence of mortality. Once the patient has recovered, investigations can be performed to confirm the diagnosis and incriminate the responsible drug. It is imperative, in order that these tests may be performed, that serum samples are taken at the time of diagnosis of the neutropenic episode, throughout its course and during the recovery period.

Abstract
Flow cytometry has been used to evaluate the functional ability of neutrophils and the expression of IgG Fc receptors (FcRII and FcRIII) in autoimmune neutropenia. Quantification of the neutrophil oxidative burst was made by assaying the production of 2'7'-dichlorofluorescein (DCF) from non-fluorescent 2'7'-dichlorofluorescein trapped within the cell, by flow cytometric analysis of cellular fluorescence. In the present study the DCF assay was used to examine the response of neutrophils to stimulation by opsonized and non-opsonized Staphylococcus aureus. In addition, the rate of uptake of S. aureus labelled with the red nuclear dye propidium iodide was determined. The presence of surface-bound immunoglobulin, which may affect the phagocytic capacity of the neutrophil, was also measured. No correlation between the neutrophil count and level of membrane-bound IgG or the rate of bacterial uptake was found. The studies were performed on twenty patients with autoimmune neutropenia, twelve with other autoimmune disorders and fourteen normal controls. The rate of uptake of bacteria was considered in relation to the expression of FcRII and FcRIII. Good correlation was found with the level of expression of FcRII, the major receptor for neutrophil activation, and the rate of uptake of bacteria (r = 0.64).

Abstract
With the ever widening group of autoimmune conditions that are beneficially affected by infusions of high dose immunoglobulin the possible mechanisms of action of such therapy appear increasingly complex. Fc mediated blockade of the mononuclear phagocyte system is an acknowledged early effect. This is, however, accompanied by a decrease of neutrophil counts which suggests that IgG binding to the neutrophil may be a mechanism of action. The decrease of neutrophil counts is transient but in immune thrombocytopenia is inversely proportional to the platelet response observed. In parallel to the effect on the neutrophil there are changes in the lymphocyte subsets with reversal of the T helper/suppressor ratio and alterations in the individual cellular constituents of each subset that correlate with the clinical response. The observed changes in B cell numbers and function suggest that T dependent and independent antibody production is effected by intravenous immunoglobulin. It is increasingly clear that in ITP at least the clinical response to IV IgG is a summation of several cellular events and their balance reflects the ultimate outcome. It may eventually be possible to use these observations to predict the likely outcome in the individual patient of this mode of therapy.

Abstract
Antigranulocyte antibodies are involved in the pathophysiology of a number of clinical disorders, which include: febrile transfusion reactions, severe pulmonary reactions to transfusion, auto-immune neutropenia, drug-induced neutropenia, and iso-immune neonatal neutropenia. Owing to the inherent difficulties of manipulating granulocytes in vitro, many of the serological techniques described for the detection of antigranulocyte antibodies are complex and sometimes difficult to reproduce. We describe the detection of alloreactive granulocyte antibodies using flow cytometric analysis of donor leucocyte suspensions in an indirect immunofluorescent test. The technique provides a semiquantitative detection of granulocyte antibodies in two groups of patients studied and, by providing as a comparison the reactivity on the corresponding mononuclear leucocytes, allows the distinction between granulocyte-specific antibodies and antibodies directed against the histocompatibility antigens.

Abstract
We report the details of a young woman in whom pericardial tamponade developed acutely following preparation for allogeneic bone marrow transplantation for acute lymphoblastic leukaemia. The aetiology of the effusion, though uncertain, probably relates to the cumulative cardiotoxicity of cyclophosphamide and irradiation upon a myocardium previously sensitised by anthracycline therapy. As the number of transplant procedures increases, this complication may become more common, and might be avoided by a more critical assessment of cardiac function prior to transplantation, with radionuclide angiography.
