Med J Armed Forces India 2023; 79:722-725. [PMID: 37981926 PMCID: PMC10654355 DOI: 10.1016/j.mjafi.2023.08.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Accepted: 08/27/2023] [Indexed: 11/21/2023] Open
Abstract
We describe two young patients with Wiskott-Aldrich Syndrome (WAS) who were treated by T-replete hematopoietic stem cell transplantation (HSCT) from the HLA haploidentical father according to a modified Baltimore protocol. Whereas similar protocols have been successfully used in various malignant and non-malignant diseases, this is the first report for this particular disease. The data being presented pertains to the report about two successful haploidentical transplants with post transplant cyclophosphamide (PTCY) after busulfan-based conditioning.

Abstract
Hematopoietic stem cell transplantation (HSCT) is curative for many non-malignant disorders. As HSCT and supportive care technologies improve, this life-saving treatment may be offered to more and more patients. With the development of new preparative regimens, expanded alternative donor availability, and graft manipulation techniques, there are many options when choosing the best regimen for patients. Herein the authors review transplant considerations, transplant goals, conditioning regimens, donor choice, and graft manipulation strategies for patients with non-malignant disorders undergoing HSCT.

Successful Allogeneic Peripheral Blood Stem Cell Transplantation in 4 Wiskott-Aldrich Syndrome Patients. J Pediatr Hematol Oncol 2022; 44:e324-e328. [PMID: 33828030 DOI: 10.1097/mph.0000000000002154] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Accepted: 02/24/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND Allogeneic hematopoietic stem cell transplantation is a potential curative treatment in Wiskott-Aldrich syndrome (WAS). Here, we analyzed the outcomes in 4 WAS patients who underwent this procedure with peripheral blood stem cell (PBSC) in our center. PATIENTS AND METHODS Four patients with severe WAS phenotype have received allogeneic hematopoietic stem cell transplantation between January 2014 and December 2019 from matched sibling donors with PBSC. Two different preparative conditioning regimens were provided: the first associated busulfan-cyclophosphamide (2 patients) and the second with busulfan-fludarabine administered to the others. Cyclosporine gave as preferred graft-versus-host disease prophylaxis with a short course of methotrexate. RESULTS All patients achieved engraftment after PBSC with a median CD34+ cell count: 13.6×106/kg (8 to 24.9×106/kg). Chronic graft-versus-host disease developed in 2 patients treated by cyclosporine-steroids with complete resolution. Chimerism for all the patients was fully donor (>95% donor). After a median follow-up of 41 months (8 to 74 mo), all patients (100%) are alive, healthy, with complete clinical, immunologic, and hematologic recovery, without signs of WAS. CONCLUSION This limited study with high-dose PBSC transplantation approach for WAS, demonstrated a safe and effective treatment option, with rapid engraftment, without complications, excellent long-term outcomes, independent of conditioning regimen.

Abstract
Allogeneic hematopoietic stem cell transplantation (HSCT) is a potentially curative treatment for patients affected by Wiskott-Aldrich syndrome (WAS). Reported HSCT outcomes have improved over time with respect to overall survival, but some studies have identified older age and HSCT from alternative donors as risk factors predicting poorer outcome. We analyzed 197 patients transplanted at EBMT centers between 2006 and 2017, who received conditioning as recommended by the inborn errors working party (IEWP): either busulfan (n=103) or treosulfan (n=94) combined with fludarabine ± thiotepa. After a median follow-up after HSCT of 44.9 months, 176 patients were alive, resulting in a 3-year overall survival of 88.7%, and chronic GVHD-free survival (CRFS; events: death, graft failure, severe chronic GVHD) of 81.7%. Overall survival and CRFS were not significantly impacted by conditioning regimen (busulfan- versus treosulfan-based), donor type (MSD/MFD vs MUD/MMUD vs. MMFD), and period of HSCT (2006-2013 vs. 2014-2017). Patients younger than 5 years at HSCT had a significantly better overall survival. The overall cumulative incidences of grade III-IV acute GVHD and extensive/moderate/severe chronic GVHD were 6.6% and 2.1%, respectively. Patients receiving treosulfan-based conditioning had a higher incidence of graft failure, mixed donor chimerism and more frequently received secondary procedures (2nd HSCT, unconditioned stem cell boost, donor lymphocyte infusion, or splenectomy). In summary, HSCT for WAS with conditioning regimens currently recommended by IEWP results in excellent survival and low rates of GVHD, regardless of donor or stem cell source, but age ≥5 years remains a risk factor for overall survival.

Abstract
The Wiskott-Aldrich syndrome (WAS) is an X-linked disorder caused by mutations in the WAS gene resulting in congenital thrombocytopenia, eczema, recurrent infections and an increased incidence of autoimmune diseases and malignancies. Without curative therapies, affected patients have diminished life expectancy and reduced quality of life. Since WAS protein (WASP) is constitutively expressed only in hematopoietic stem cell-derived lineages, hematopoietic stem cell transplantation (HSCT) and gene therapy (GT) are well suited to correct the hematologic and immunologic defects. Advances in high-resolution HLA typing, new techniques to prevent GvHD allowing the use of haploidentical donors, and the introduction of reduced intensity conditioning regimens with myeloablative features have increased overall survival (OS) to over 90%. The development of GT for WAS has provided basic knowledge into vector selection and random integration of various viral vectors into the genome, with the possibility of inducing leukemogenesis. After trials and errors, inactivating lentiviral vectors carrying the WAS gene were successfully evaluated in clinical trials, demonstrating cure of the disease except for insufficient resolution of the platelet defect. Thus, 50 years of clinical evaluation, genetic exploration and extensive clinical trials, a lethal syndrome has turned into a curable disorder.

Abstract
Wiskott-Aldrich syndrome (WAS) is an X-linked disease caused by mutations in the WAS gene, leading to thrombocytopenia, eczema, recurrent infections, autoimmune disease, and malignancy. Hematopoietic cell transplantation (HCT) is the primary curative approach, with the goal of correcting the underlying immunodeficiency and thrombocytopenia. HCT outcomes have improved over time, particularly for patients with HLA-matched sibling and unrelated donors. We report the outcomes of 129 patients with WAS who underwent HCT at 29 Primary Immune Deficiency Treatment Consortium centers from 2005 through 2015. Median age at HCT was 1.2 years. Most patients (65%) received myeloablative busulfan-based conditioning. With a median follow-up of 4.5 years, the 5-year overall survival (OS) was 91%. Superior 5-year OS was observed in patients <5 vs ≥5 years of age at the time of HCT (94% vs 66%; overall P = .0008). OS was excellent regardless of donor type, even in cord blood recipients (90%). Conditioning intensity did not affect OS, but was associated with donor T-cell and myeloid engraftment after HCT. Specifically, patients who received fludarabine/melphalan-based reduced-intensity regimens were more likely to have donor myeloid chimerism <50% early after HCT. In addition, higher platelet counts were observed among recipients who achieved full (>95%) vs low-level (5%-49%) donor myeloid engraftment. In summary, HCT outcomes for WAS have improved since 2005, compared with prior reports. HCT at a younger age continues to be associated with superior outcomes supporting the recommendation for early HCT. High-level donor myeloid engraftment is important for platelet reconstitution after either myeloablative or busulfan-containing reduced intensity conditioning. (This trial was registered at www.clinicaltrials.gov as #NCT02064933.).

Abstract
Both Wiskott-Aldrich syndrome (WAS) and dedicator of cytokinesis 8 (DOCK8) deficiency are primary immunodeficiency diseases caused by mutations in genes that result in defective organization of the cytoskeleton in hematopoietic tissues. They share some overlapping features such as a combined immunodeficiency, eczema and a predisposition to autoimmunity and malignancy, but also have some unique features that make them relatively easy to diagnose by clinical means. Both diseases can be cured by HSCT in a large proportion of patients. In WAS it is sometimes difficult to establish an indication for HSCT due to the large variability of disease severity, while HSCT is probably indicated in all patients affected by DOCK8 deficiency. There is considerably more published HSCT experience for WAS than for DOCK8 deficiency, but many open questions remain, which will be discussed in this review.

Abstract
INTRODUCTION Hematopoietic stem cell transplantation (HSCT) is an established curative treatment for many primary immunodeficiencies. Advances in donor selection, graft manipulation, conditioning and treatment of complications, mean that survival for many conditions is now around 90%. Next generation sequencing is identifying new immunodeficiencies, many of which are treatable with HSCT. Challenges remain however with short and long-term sequalae. This article reviews latest developments in HSCT for conventional primary immunodeficiencies and presents data on outcome for emerging diseases, Areas covered: This article reviews recently published literature detailing advances, particularly in conditioning regimens and new methods of T-lymphocyte depletion, as well as new information regarding approach and out come of transplanting patients with conventional primary immunodeficiencies. The article reviews data regarding transplant outcomes for newly described primary immunodeficiencies, particularly those associated with gain-of-function mutations. Expert commentary: New methods of graft manipulation have had significant impact on HSCT outcomes, with the range of PIDs treated using T-lymphocyte depletion significantly expanded. Outcomes for newly described diseases with variable phenotypes and clinical features, transplanted when the diagnosis was unknown are beginning to be described, and will improve as patients are identified earlier, and targeted therapies such as JAK inhibitors are used as a bridge to transplantation.

Abstract
Until recently, hematopoietic stem cell transplantation was the only curative option for Wiskott-Aldrich syndrome (WAS). The first attempts at gene therapy for WAS using a ϒ-retroviral vector improved immunological parameters substantially but were complicated by acute leukemia as a result of insertional mutagenesis in a high proportion of patients. More recently, treatment of children with a state-of-the-art self-inactivating lentiviral vector (LV-w1.6 WASp) has resulted in significant clinical benefit without inducing selection of clones harboring integrations near oncogenes. Here, we describe a case of a presplenectomized 30-year-old patient with severe WAS manifesting as cutaneous vasculitis, inflammatory arthropathy, intermittent polyclonal lymphoproliferation, and significant chronic kidney disease and requiring long-term immunosuppressive treatment. Following reduced-intensity conditioning, there was rapid engraftment and expansion of a polyclonal pool of transgene-positive functional T cells and sustained gene marking in myeloid and B-cell lineages up to 20 months of observation. The patient was able to discontinue immunosuppression and exogenous immunoglobulin support, with improvement in vasculitic disease and proinflammatory markers. Autologous gene therapy using a lentiviral vector is a viable strategy for adult WAS patients with severe chronic disease complications and for whom an allogeneic procedure could present an unacceptable risk.

Abstract
Hematopoietic stem/progenitor cells (HSPCs) are capable of supporting the lifelong production of blood cells exerting a wide spectrum of functions. Lentiviral vector HSPC gene therapy generates a human hematopoietic system stably marked at the clonal level by vector integration sites (ISs). Using IS analysis, we longitudinally tracked >89,000 clones from 15 distinct bone marrow and peripheral blood lineages purified up to 4 years after transplant in four Wiskott-Aldrich syndrome patients treated with HSPC gene therapy. We measured at the clonal level repopulating waves, populations' sizes and dynamics, activity of distinct HSPC subtypes, contribution of various progenitor classes during the early and late post-transplant phases, and hierarchical relationships among lineages. We discovered that in-vitro-manipulated HSPCs retain the ability to return to latency after transplant and can be physiologically reactivated, sustaining a stable hematopoietic output. This study constitutes in vivo comprehensive tracking in humans of hematopoietic clonal dynamics during the early and late post-transplant phases. Hematopoietic reconstitution occurs in two distinct clonal waves A few thousand HSPC clones stably sustain multilineage blood cell production Steady-state hematopoiesis after transplant is maintained by both HSCs and MPPs Natural killer clones have closer relationships to myeloid cells than to lymphoid cells

Abstract
Stem cells are characterized by a number of useful properties, including their ability to migrate, differentiate, and secrete a variety of therapeutic molecules such as immunomodulatory factors. As such, numerous pre-clinical and clinical studies have utilized stem cell-based therapies and demonstrated their tremendous potential for the treatment of various human diseases and disorders. Recently, efforts have focused on engineering stem cells in order to further enhance their innate abilities as well as to confer them with new functionalities, which can then be used in various biomedical applications. These engineered stem cells can take on a number of forms. For instance, engineered stem cells encompass the genetic modification of stem cells as well as the use of stem cells for gene delivery, nanoparticle loading and delivery, and even small molecule drug delivery. The present Review gives an in-depth account of the current status of engineered stem cells, including potential cell sources, the most common methods used to engineer stem cells, and the utilization of engineered stem cells in various biomedical applications, with a particular focus on tissue regeneration, the treatment of immunodeficiency diseases, and cancer.

Abstract
PURPOSE OF REVIEW The Wiskott-Aldrich syndrome (WAS), caused by mutations in the WAS gene, is a complex and diverse disorder with X-linked inheritance. This review focuses on recent developments in the understanding of its basic pathophysiology, diverse clinical phenotypes and optimal patient management including novel therapies. RECENT FINDINGS The protein encoded by the WAS gene is a multifunctional signaling element expressed in immune and hematopoietic cells that plays a critical role in cytoskeletal reorganization, immune synapse formation and intracellular signaling. The type of specific mutation, its location within the gene and its effect on protein expression play a major role in determining an individual patient's clinical phenotype. Recent clinical observations and molecular studies have created a sophisticated picture of the disease spectrum. The improved outcome of stem cell transplantation from related and unrelated matched donors and promising early results from the first clinical gene therapy trial have added new therapeutic options for these patients. SUMMARY Classic WAS, X-linked thrombocytopenia and X-linked neutropenia are caused by WAS gene mutations, each having a distinct pattern of clinical symptoms and disease severity. New developments in the understanding of these syndromes and novel therapeutic options will have a major impact on the treatment of individuals with WAS mutations.

Abstract
Allogeneic hematopoietic stem cell transplantation has been shown to be curative for well-described as well as newly discovered immunodeficiencies. However, it is difficulty to define a universal transplant regimen given the rarity of these disorders and the varied pathophysiology these disorders encompass. This article discusses those primary immunodeficiencies most commonly treated by hematopoietic stem cell transplant and describes the transplant issues specific to these disorders.

Abstract
We report a novel mutation in a boy with Wiskott-Aldrich syndrome (WAS) who was 4 years and 10 months of age and underwent successful umbilical cord blood transplantation (UCBT). The child presented at 3 months of age with symptomatic thrombocytopenia and eczema. Despite a large dose of intravenous immunoglobulin treatment, no increase in the platelet count was observed. A genetic analysis revealed a deletion mutation at c.410_419del10 in exon 4, which resulted in the replacement of encoded phenylalanine with serine at amino acid 137 and caused an early stop codon at downstream amino acid 121 (p.F137SfsX121), and confirmed a diagnosis of WAS. The only curative treatment for WAS is hematopoietic stem cell transplantation. Because no matched sibling donor was available, he underwent unrelated UCBT. He is currently alive and doing well at fourteen months post-transplant, and he is free of any bleeding episodes. The eczema that was all over his body had disappeared. This case suggests that unrelated UCBT may be safe and technically feasible for the treatment of WAS when an appropriately matched related or unrelated donor is unavailable.

Abstract
Wiskott–Aldrich syndrome (WAS) is a rare X-linked primary immunodeficiency disorder characterized by the triad of eczema, thrombocytopenia, and severe and often recurrent infections. Despite the rarity of this disorder, our understanding of the molecular and cellular pathogenesis of WAS has continued to increase. Advances in the use of diagnostic tools, the provision of supportive care, and improvements in allogeneic hematopoietic stem cell transplantation have significantly reduced the morbidity and mortality associated with this disorder. Exciting advancements in the care of patients with WAS have also occurred, including the successful application of autologous gene-modified hematopoietic stem cell transplantation.

Abstract
Gastrointestinal disorders such as chronic or acute diarrhea, malabsorption, abdominal pain, and inflammatory bowel diseases can indicate immune deficiency. The gastrointestinal tract is the largest lymphoid organ in the body, so it is not surprising that intestinal diseases are common among immunodeficient patients. Gastroenterologists therefore must be able to diagnose and treat patients with primary immunodeficiency. Immune-related gastrointestinal diseases can be classified as those that develop primarily via autoimmunity, infection, an inflammatory response, or malignancy. Immunodeficient and immunocompetent patients with gastrointestinal diseases present with similar symptoms. However, intestinal biopsy specimens from immunodeficient patients often have distinct histologic features, and these patients often fail to respond to conventional therapies. Therefore, early recognition of symptoms and referral to an immunologist for a basic immune evaluation is required to select appropriate treatments. Therapies for primary immunodeficiency comprise immunoglobulin replacement, antibiotics, and, in severe cases, bone marrow transplantation. Treatment of immunodeficient patients with concomitant gastrointestinal disease can be challenging, and therapy with immunomodulators often is required for severe disease. This review aims to guide gastroenterologists in the diagnosis and treatment of patients with primary immunodeficiency.

Abstract
Infection with human papillomavirus (HPV) is almost universal and eventually asymptomatic, but pathologic infection with HPV is severe, recurrent, and recalcitrant to therapy. It is also an underappreciated manifestation of primary immunodeficiency. Mutations in EVER1, EVER2, GATA2, CXCR4, and dedicator of cytokinesis 8 (DOCK8) are typically associated with extensive HPV infections, whereas several other primary immune defects result in severe HPV much less frequently. We review immunodeficiencies with severe HPV infections and the mechanisms underlying them.

Abstract
The chapter of inherited thrombocytopenias has expanded greatly over the last decade and many "new" forms deriving from mutations in "new" genes have been identified. Nevertheless, nearly half of patients remain without a definite diagnosis because their illnesses have not yet been described. The diagnostic approach to these diseases can still take advantage of the algorithm proposed by the Italian Platelet Study Group in 2003, although an update is required to include the recently described disorders. So far, transfusions of platelet concentrates have represented the main tool for preventing or treating bleedings, while haematopoietic stem cell transplantation has been reserved for patients with very severe forms. However, recent disclosure that an oral thrombopoietin mimetic is effective in increasing platelet count in patients with MYH9-related thrombocytopenia opened new therapeutic perspectives. This review summarizes the general aspects of inherited thrombocytopenias and describes in more detail MYH9-related diseases (encompassing four thrombocytopenias previously recognized as separate diseases) and the recently described ANKRD26-related thrombocytopenia, which are among the most frequent forms of inherited thrombocytopenia.

Abstract
Conventional myeloablative conditioning regimens prior to hematopoietic cell transplantation (HCT) are associated with significant transplant-related morbidity and mortality in children affected by primary immunodeficiency disorders. Reduced-intensity conditioning regimens have been extensively used without severe acute toxicity in patients with pre-HCT comorbidities, with the additional advantage of reducing or avoiding long-term sequelae such as infertility and growth retardation. Compared with myeloablative HCT, reduced-intensity conditioning regimens are associated with an increased incidence of mixed donor chimerism and graft rejection. While mixed donor engraftment is likely to correct the phenotypic expression of most children with primary immunodeficiency disorders, the use of donor lymphocyte infusion to increase donor chimerism or second HCT procedures may be required in some cases. Here we discuss the most recent data on the use of different reduced-intensity conditioning protocols in children with primary immunodeficiency disorders, highlighting significant clinical lessons and areas that need additional study.

Abstract
Wiskott-Aldrich Syndrome (WAS) is a severe X-linked Primary Immunodeficiency that affects 1-10 out of 1 million male individuals. WAS is caused by mutations in the WAS Protein (WASP) expressing gene that leads to the absent or reduced expression of the protein. WASP is a cytoplasmic protein that regulates the formation of actin filaments in hematopoietic cells. WASP deficiency causes many immune cell defects both in humans and in the WAS murine model, the Was(-/-) mouse. Both cellular and humoral immune defects in WAS patients contribute to the onset of severe clinical manifestations, in particular microthrombocytopenia, eczema, recurrent infections, and a high susceptibility to develop autoimmunity and malignancies. Autoimmune diseases affect from 22 to 72% of WAS patients and the most common manifestation is autoimmune hemolytic anemia, followed by vasculitis, arthritis, neutropenia, inflammatory bowel disease, and IgA nephropathy. Many groups have widely explored immune cell functionality in WAS partially explaining how cellular defects may lead to pathology. However, the mechanisms underlying the occurrence of autoimmune manifestations have not been clearly described yet. In the present review, we report the most recent progresses in the study of immune cell function in WAS that have started to unveil the mechanisms contributing to autoimmune complications in WAS patients.

Abstract
HLA-identical sibling donor transplantation remains the treatment of choice for Wiskott-Aldrich Syndrome (WAS). Since 1990, utilization of alternative donor sources has increased significantly. We report the hematopoietic cell transplantation (HCT) outcomes of 47 patients with WAS treated at a single center since 1990. Improved outcomes were observed after 2000 despite the increased number of alternative donors. Five-year OS improved from 62.5% (95% CI: 34.9% to 81.1%) to 90.8% (95% CI: 67.7% to 97.6%) for patients transplanted during 1990-2000 and 2001-2009, respectively. In multivariate analysis, transplant era significantly impacted OS (P=0.04), whereas age was only marginally significant (P=0.06, Cox proportional hazard analysis). No TRM occurred within the first 100 days among patients transplanted during 2001-2009 compared with 3/16 during 1990-2000, (P=0.03, Fisher's exact test). The extent of HLA mismatch did not significantly affect the incidence of acute GVHD, chronic GVHD or survival. Post-HCT autoimmune cytopenias were frequently diagnosed after 2001: 17/31 (55%) patients. Their occurrence was not associated with transplant donor type (P=0.53), acute GVHD (P=0.74), chronic GVHD (P=0.12), or post-transplant mixed chimerism (P=0.50).

Abstract
Wiskott-Aldrich syndrome (WAS) is a rare X-linked primary immunodeficiency caused by the defective expression of the WAS protein (WASP) in hematopoietic cells. It has been shown that dendritic cells (DCs) are functionally impaired in WAS patients and was−/− mice. We have previously demonstrated the efficacy and safety of a murine model of WAS gene therapy (GT), using stem cells transduced with a lentiviral vector. The aim of this study was to investigate whether GT can correct DC defects in was−/− mice. As DCs expressing WASP were detected in the secondary lymphoid organs of the treated mice, we tested the in vitro and in vivo function of bone marrow-derived DCs (BMDCs). The BMDCs showed efficient in vitro uptake of latex beads and Salmonella typhimurium. When BMDCs from the treated mice (GT BMDCs) and the was−/− mice were injected into wild type hosts, we found a higher number of cells that had migrated to the draining lymph nodes compared to mice injected with was−/− BMDCs. Finally, we found that OVA-pulsed GT BMDCs or vaccination with anti-DEC205 OVA fusion protein can efficiently induce antigen-specific T cell activation in vivo. These findings show that WAS GT significantly improves DC function, thus adding new evidence of the preclinical efficacy of lentiviral vector-mediated WAS GT.

Abstract
We report a successful umbilical cord blood transplantation (UCBT) in an 8-month male with Wiskott-Aldrich syndrome (WAS) and congenital cytomegalovirus (CMV) infection. The child presented at 3 months of age with symptomatic thrombocytopenia and CMV infection. Despite appropriate antiviral treatment no rise in the platelet count was observed. Genetic analysis confirmed the diagnosis of WAS. The clinical course was complicated by severe CMV retinitis with bilateral retinal hemorrhages and renal vasculitis. He underwent unrelated UCBT resulting in a rapid resolution of autoimmunity and thrombocytopenia.

Abstract
Hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs) are both adult stem cells residing in the bone marrow. MSCs interact with HSCs, they stimulate and enhance the proliferation of HSCs by secreting regulatory molecules and cytokines, providing a specialized microenvironment for controlling the process of hematopoiesis. In this paper we discuss how MSCs contribute to HSC niche, maintain the stemness and proliferation of HSCs, and support HSC transplantation.

Abstract
Wiskott-Aldrich syndrome is a rare X-linked immunodeficiency disorder that is characterized by a variable clinical phenotype. Matched donor bone marrow transplantation is currently the only curative therapeutic option. We present the case of a 24-year-old male who was diagnosed at the age of seven with Wiskott-Aldrich syndrome. He did not respond to intravenous gammaglobulin and he experienced recurrent pulmonary infections despite prophylactic antibiotics. The patient had no matched donor. At the age of nine, he was submitted to splenectomy and his platelet count was normalized. Fifteen years later, the patient remains asymptomatic with a normal platelet count. He is still receiving prophylactic antibiotics and no bleeding episodes or septic complications have been reported. This case demonstrates that splenectomy can represent a safe therapeutic option in selected WAS patients, provided that there is a tight follow-up program, patient education and adherence to guidelines regarding post-splenectomy prophylaxis.

Abstract
OBJECTIVE To alert endocrinologists about the potential for karyotype confusion in patients who have undergone bone marrow transplantation. METHODS Clinical, laboratory, and imaging data are reported on a young adult male patient who initially presented because of concerns about short stature. RESULTS An 18-year-old fully virilized male patient with a history of Wiskott-Aldrich syndrome had undergone successful bone marrow transplantation in infancy. The donor was his older sister. Many years later, he underwent evaluation because of short stature and was found to have a 46, XX karyotype. This unexpected finding led to several costly laboratory and imaging studies, as well as a new diagnosis of a disorder of sex development. The patient was referred to our medical center for further evaluation of XX sex reversal. A skin biopsy was eventually performed, which revealed a 46, XY karyotype. This unusual case highlights the fact that a peripheral blood specimen from bone marrow transplant recipients reflects the genetic makeup of the bone marrow donor. CONCLUSION Although the cytogenetic changes that occur in recipients of bone marrow transplants are well known to hematologists and oncologists, they are not commonly recognized by other health care providers. Increased awareness of this potential situation in long-term survivors of bone marrow transplantation is needed.

Abstract
In this retrospective collaborative study, we have analyzed long-term outcome and donor cell engraftment in 194 patients with Wiskott-Aldrich syndrome (WAS) who have been treated by hematopoietic cell transplantation (HCT) in the period 1980- 2009. Overall survival was 84.0% and was even higher (89.1% 5-year survival) for those who received HCT since the year 2000, reflecting recent improvement of outcome after transplantation from mismatched family donors and for patients who received HCT from an unrelated donor at older than 5 years. Patients who went to transplantation in better clinical conditions had a lower rate of post-HCT complications. Retrospective analysis of lineage-specific donor cell engraftment showed that stable full donor chimerism was attained by 72.3% of the patients who survived for at least 1 year after HCT. Mixed chimerism was associated with an increased risk of incomplete reconstitution of lymphocyte count and post-HCT autoimmunity, and myeloid donor cell chimerism < 50% was associated with persistent thrombocytopenia. These observations indicate continuous improvement of outcome after HCT for WAS and may have important implications for the development of novel protocols aiming to obtain full correction of the disease and reduce post-HCT complications.

Abstract
Many primary immunodeficiency disorders (PIDD) are associated with elevated risks for different types of cancer. Defective immunosurveillance mechanisms in PIDD and infection with oncogenic viruses (eg, Epstein Barr, herpesvirus 8) seem to have significant contributory roles in many cases. Non-Hodgkin lymphoma and Hodgkin disease are two of the most common PIDD-associated malignancies. The impact of PIDD-associated malignancy has increased in recent years in parallel with improved patient with PIDD survival and longevity, due largely to effective immunoglobulin replacement therapy. Epidemiologic data, clinical patterns, and management considerations of the common PIDD-associated cancers are reviewed.

Abstract
Wiskott-Aldrich syndrome (WAS) is a rare X-linked recessive immunodeficiency disorder of childhood that is caused by mutations in the WAS gene. WAS encodes WASp, a protein that is known to function in the cytoplasm of hematopoietic cells and is required for the induced differentiation of CD4+ T helper type 1 (TH1) lymphocytes. Now, a paper in Science Translational Medicine describes another mechanism for impaired immunity in WAS by showing that WASp localizes in the nucleus and regulates histone modifications and chromatin structure, thereby modulating expression of the TH1 master gene TBX21 (TBET).

Abstract
The Wiskott-Aldrich syndrome (WAS) is an X-linked disorder characterized by a triad of diagnostic clinical elements: immunodeficiency, eczema, and hemorrhage caused by thrombocytopenia with small-sized platelets. The formal proof that hematopoietic cell transplantation (HCT) could be used to cure WAS revealed a requirement for both immunosuppression and myelosuppression that still underlies the standard approach to curative therapy today. The current short- and long-term toxicities of HCT are the main stumbling block for the ability to cure every patient with WAS and X-linked thrombocytopenia, and much remains to be done.

Abstract
Many advances have been made since the first successful hematopoietic cell transplants (HCT) in children with primary immunodeficiency disorders (PID) were reported 40 years ago, and many children with PID can now be cured from their otherwise lethal disorders through well-matched HCT procedures. Preexisting morbidity and infection remain the principal adverse factors for poor outcomes with HCT. To improve current results, earlier diagnosis, well-tolerated pretransplant conditioning regimens, and promotion of immune reconstitution need to be considered. This article addresses modifications in the conditioning regimen that might lead to further improvement in HCT outcomes.

Transplantation of hematopoietic stem cells and long-term survival for primary immunodeficiencies in Europe: entering a new century, do we do better? J Allergy Clin Immunol 2010; 126:602-10.e1-11.

Abstract
BACKGROUND Hematopoietic stem cell transplantation remains the only treatment for most patients with severe combined immunodeficiencies (SCIDs) or other primary immunodeficiencies (non-SCID PIDs). OBJECTIVE To analyze the long-term outcome of patients with SCID and non-SCID PID from European centers treated between 1968 and 2005. METHODS The product-limit method estimated cumulative survival; the log-rank test compared survival between groups. A Cox proportional-hazard model evaluated the impact of independent predictors on patient survival. RESULTS In patients with SCID, survival with genoidentical donors (n = 25) from 2000 to 2005 was 90%. Survival using a mismatched relative (n = 96) has improved (66%), similar to that using an unrelated donor (n = 46; 69%; P = .005). Transplantation after year 1995, a younger age, B(+) phenotype, genoidentical and phenoidentical donors, absence of respiratory impairment, or viral infection before transplantation were associated with better prognosis on multivariate analysis. For non-SCID PID, in contrast with patients with SCID, we confirm that, in the 2000 to 2005 period, using an unrelated donor (n = 124) gave a 3-year survival rate similar to a genoidentical donor (n = 73), 79% for both. Survival was 76% in phenoidentical transplants (n = 23) and worse in mismatched related donor transplants (n = 47; 46%; P = .016). CONCLUSION This is the largest cohort study of such patients with the longest follow-up. Specific issues arise for different patient groups. Patients with B-SCID have worse survival than other patients with SCID, despite improvements in each group. For non-SCID PID, survival is worse than SCID, although more conditions are now treated. Individual disease categories now need to be analyzed so that disease-specific prognosis may be better understood and the best treatments planned.

Abstract
The clinical data of 24 children with Wiskott-Aldrich syndrome (WAS) from 23 unrelated Chinese families were reviewed in the present study. WAS protein (WASP) expression in peripheral blood mononuclear cells was examined by flow cytometry (FCM); WASP gene was amplified by PCR and directly sequenced to analyze mutations in the WASP gene in patients and their female relatives. FCM analysis of 21 patients showed that 18 cases were WASP-negative, and three had partially WASP expression. WASP gene analysis revealed mutations in 23 patients, including five missense mutations, four nonsense mutations, four deletion mutations, three insertion mutations, six splice site mutations, and one complex mutation, among which, 20 unique mutations were detected, including seven novel mutations (168 C>A, 747-748del T, 793-797del C, 1185 ins C, Dup 1251-1267, 1277 insA and 1266 C>G; 1267-1269del C). Five WAS children underwent stem cell transplantation. After 2 months of transplantation, WASP expression was restored to normal in all five patients whereas one patient died of cytomegalovirus-induced interstitial lung disease. WASP gene analysis can make a definite diagnosis of WAS and identify mutation carriers, beneficial for timely treatment and genetic counseling for children with WAS.

Abstract
Primary immune deficiencies (PIDs) are rare diseases, and most are lethal without appropriate intervention. Hematopoietic cell transplantation (HCT) can cure the majority of patients, but most lack a suitable matched related donor. Alternative donor stem cells (mismatched related donor bone marrow, unrelated donor bone marrow, and unrelated donor umbilical cord blood [UCB]) are therefore frequently required. Published data comparing outcomes after alternative donor transplant for PID are scarce. The outcomes and potential advantage and disadvantages of each alternative stem cell source are discussed in this chapter. Although there are insufficient prospective data to make meaningful comparisons between the alternative stem cell sources, the results presented here demonstrate clearly that the use of UCB transplantation for PID is a viable option and may be advantageous in many situations.

Abstract
Advances in immunology have led to a breathtaking expansion of recognized primary immunodeficiency diseases (PID) with over 120 disease-related genes identified. In North America alone more than 1000 children have received allogeneic blood or marrow transplant over the past 30 years, with the majority surviving long term. This review presents results and highlights challenges and notable advances, including novel less toxic conditioning regimens, to transplant the more common and severe forms of PID. HLA-matched sibling donors remain the ideal option, however, advances in living donor unrelated HSCT and banked umbilical cord blood grafts provide hope for all children with severe PID.

Abstract
Abstract
Wiskott-Aldrich syndrome (WAS) is a severe X-linked immunodeficiency caused by mutations in the gene encoding for WASP, a key regulator of signaling and cytoskeletal reorganization in hematopoietic cells. Mutations in WASP result in a wide spectrum of clinical manifestations ranging from the relatively mild X-linked thrombocytopenia to the classic full-blown WAS phenotype characterized by thrombocytopenia, immunodeficiency, eczema, and high susceptibility to developing tumors and autoimmune manifestations. The life expectancy of patients affected by severe WAS is reduced, unless they are successfully cured by bone marrow transplantation from related identical or matched unrelated donors. Because many patients lack a compatible bone marrow donor, the administration of WAS gene–corrected autologous hematopoietic stem cells could represent an alternative therapeutic approach. In the present review, we focus on recent progress in understanding the molecular and cellular mechanisms contributing to the pathophysiology of WAS. Although molecular and cellular studies have extensively analyzed the mechanisms leading to defects in T, B, and dendritic cells, the basis of autoimmunity and thrombocytopenia still remains poorly understood. A full understanding of these mechanisms is still needed to further implement new therapeutic strategies for this peculiar immunodeficiency.

Abstract
Wiskott-Aldrich Syndrome (WAS) is a life-threatening X-linked disease characterized by immunodeficiency, thrombocytopenia, autoimmunity, and malignancies. Gene therapy could represent a therapeutic option for patients lacking a suitable bone marrow (BM) donor. In this study, we analyzed the long-term outcome of WAS gene therapy mediated by a clinically compatible lentiviral vector (LV) in a large cohort of was(null) mice. We demonstrated stable and full donor engraftment and Wiskott-Aldrich Syndrome protein (WASP) expression in various hematopoietic lineages, up to 12 months after gene therapy. Importantly, we observed a selective advantage for T and B lymphocytes expressing transgenic WASP. T-cell receptor (TCR)-driven T-cell activation, as well as B-cell's ability to migrate in response to CXCL13, was fully restored. Safety was evaluated throughout the long-term follow-up of primary and secondary recipients of WAS gene therapy. WAS gene therapy did not affect the lifespan of treated animals. Both hematopoietic and nonhematopoietic tumors arose, but we excluded the association with gene therapy in all cases. Demonstration of long-term efficacy and safety of WAS gene therapy mediated by a clinically applicable LV is a key step toward the implementation of a gene therapy clinical trial for WAS.

Abstract
Stem cells are self-renewing multipotent progenitors with the broadest developmental potential in a given tissue at a given time. Normal stem cells in the adult organism are responsible for renewal and repair of aged or damaged tissue. Adult stem cells are present in virtually all tissues and during most stages of development. In this review, we introduce the reader to the basic information about the field. We describe selected stem cell isolation techniques and stem cell markers for various stem cell populations. These include makers for endothelial progenitor cells (CD146/MCAM/MUC18/S-endo-1, CD34, CD133/prominin, Tie-2, Flk1/KD/VEGFR2), hematopoietic stem cells (CD34, CD117/c-Kit, Sca1), mesenchymal stem cells (CD146/MCAM/MUC18/S-endo-1, STRO-1, Thy-1), neural stem cells (CD133/prominin, nestin, NCAM), mammary stem cells (CD24, CD29, Sca1), and intestinal stem cells (NCAM, CD34, Thy-1, CD117/c-Kit, Flt-3). Separate section provides a concise summary of recent clinical trials involving stem cells directed towards improvement of a damaged myocardium. In the last part of the review, we reflect on the field and on future developments.

Abstract
Development of hematopoietic cells depends on a dynamic actin cytoskeleton. Here we demonstrate that expression of the cytoskeletal regulator WASP, mutated in the Wiskott-Aldrich syndrome, provides selective advantage for the development of naturally occurring regulatory T cells, natural killer T cells, CD4(+) and CD8(+) T lymphocytes, marginal zone (MZ) B cells, MZ macrophages, and platelets. To define the relative contribution of MZ B cells and MZ macrophages for MZ development, we generated wild-type and WASP-deficient bone marrow chimeric mice, with full restoration of the MZ. However, even in the presence of MZ macrophages, only 10% of MZ B cells were of WASP-deficient origin. We show that WASP-deficient MZ B cells hyperproliferate in vivo and fail to respond to sphingosine-1-phosphate, a crucial chemoattractant for MZ B-cell positioning. Abnormalities of the MZ compartment in WASP(-/-) mice lead to aberrant uptake of Staphylococcus aureus and to a reduced immune response to TNP-Ficoll. Moreover, WASP-deficient mice have increased levels of "natural" IgM antibodies. Our findings reveal that WASP regulates both development and function of hematopoietic cells. We demonstrate that WASP deficiency leads to an aberrant MZ that may affect responses to blood-borne pathogens and peripheral B-cell tolerance.

Abstract
BMT is curative in almost 75% of children affected by severe primary immunodeficiencies (PIDs). Recently, the chance of cure has increased thanks to the availability of matched unrelated donors (MUDs). Nevertheless, besides the conventional indications to BMT (profound or absent T-cell function, profound or absent natural killer function, known syndromes with T-cell deficiencies), indications to BMT for PIDs affecting the quality of life or having an expectation of life that does not exceed the third-fourth decade remain unclear. Infact, if it is evident that the survival rate in an infant grafted for a PID with a MUD is expected to be more than 80%, alternative treatments such as gene therapy are now available.
