Abstract
Autologous haematopoietic stem cell transplantation for systemic scleroderma, developed over more than 25 years, has shown in three randomised controlled clinical trials a significant impact not only in event-free survival, overall survival, cutaneous and pulmonary involvement, but also in the quality of life of patients living with recent severe diffuse cutaneous systemic scleroderma, compared with IV cyclophosphamid despite a transplant-related mortality between 2.4 and 10%. No immunosuppressants or biologics have shown such an impact on mortality in this disease. The risk of relapse is estimated between 9 and 24%, two years after transplant. On the basis of these results, French and international guidelines now position autologous haematopoietic stem cell transplantation as a level 1A evidence-based therapeutic alternative in severe early and rapidly progressive systemic scleroderma.

Abstract
Autoimmune diseases are an important field for the development of bone marrow transplantation, or hematopoietic stem cell transplantation. In Europe alone, almost 3000 procedures have been registered so far. The Brazilian Society for Bone Marrow Transplantation (Sociedade Brasileira de Transplantes de Medula Óssea) organized consensus meetings for the Autoimmune Diseases Group, to review the available literature on hematopoietic stem cell transplantation for autoimmune diseases, aiming to gather data that support the procedure for these patients. Three autoimmune diseases for which there are evidence-based indications for hematopoietic stem cell transplantation are multiple sclerosis, systemic sclerosis and Crohn's disease. The professional stem cell transplant societies in America, Europe and Brazil (Sociedade Brasileira de Transplantes de Medula Óssea) currently consider hematopoietic stem cell transplantation as a therapeutic modality for these three autoimmune diseases. This article reviews the evidence available.

Abstract
Transected spinal cord injury (SCT) is a devastating clinical disease that strongly affects a patient’s daily life and remains a great challenge for clinicians. Stem-cell therapy has been proposed as a potential therapeutic modality for SCT. To investigate the effects of hematopoietic stem cells (HSCs) on the recovery of structure and function in SCT rats and to explore the mechanisms associated with recovery, 57 adult Sprague-Dawley rats were randomly divided into sham (n = 15), SCT (n = 24), and HSC transplantation groups (n = 15). HSCs (passage 3) labeled by Hoechst 33342, were transplanted intraspinally into the rostral, scar and caudal sites of the transected lesion at 14 days post-operation. Both in vitro and in vivo, HSCs exhibited a capacity for cell proliferation and differentiation. Following HSC transplantation, the animals’ Basso, Beattie, and Bresnahan (BBB). locomotion scale scores increased significantly between weeks 4 and 24 post-SCT, which corresponded to an increased number of 5-hydroxytryptamine (5-HT) fibers and oligodendrocytes. The amount of astrogliosis indicated by immunohistochemical staining, was markedly decreased. Moreover, the decreased expression of neurotrophin- 3 (NT-3) and mitogen-activated protein kinase kinase-1 (MEK-1) after SCT was effectively restored by HSC transplantation. The data from the current study indicate that intraspinally administered HSCs in the chronic phase of SCT results in an improvement in neurological function. Further, the results indicate that intraspinally administered HSCs benefit the underlying mechanisms involved in the enhancement of 5-HT-positive fibers and oligogenesis, the suppression of excessive astrogliosis and the upregulation of NT3-regulated MEK-1 activation in the spinal cord. These crucial findings reveal not only the mechanism of cell therapy, but may also contribute to a novel therapeutic target for the treatment of spinal cord injury (SCI).

Abstract
Refractory celiac disease (RCD) affects patients who have failed to heal after 6-12 months of a strict gluten-free diet (GFD) and when other causes of symptoms (including malignancy) have been ruled out. It may also occur in patients who previously had responded to a long-term GFD. RCD may be categorized as RCD1 (normal immunophenotype) and RCD2 (aberrant immunophenotype). RCD1 usually responds to a continued GFD, nutritional support, and therapeutic agents such as corticosteroids. In contrast, clinical response in RCD2 is incomplete and prognosis is often poor. RCD (particularly RCD2) is associated with serious complications, such as ulcerative jejunitis and enteropathy-associated T-cell lymphoma (EATL). Strict clinical and laboratory criteria should be used to diagnose RCD and specialized tests for aberrancy and clonality should be interpreted in the context of their sensitivity and specificity. Adequate nutritional support and anti-inflammatory treatment may even allow patients with RCD2 to attain a clinical remission.

Abstract
BACKGROUND AND AIMS Autologous haematopoietic stem cell transplantation (HSCT) is considered a salvage therapy for patients with refractory immune-mediated diseases. Syngeneic HSCT may be an alternative to autologous HSCT, with potential advantages in terms of safety and efficacy. METHODS A patient with severe Crohn's disease refractory to available medical therapies underwent a syngeneic HSCT from her identical twin sister. Cyclophosphamide and rabbit anti-thymocyte globulin were administered for conditioning. RESULTS After transplant, the patient presented successful engraftment, complete haematological and immunological reconstitution, and no severe complications. The patient achieved complete remission after transplant which is sustained 4 years after transplantation without any active treatment for Crohn's disease. CONCLUSIONS Patients with refractory immune-mediated diseases who have an identical disease-free twin may benefit from a syngeneic HSCT.

Abstract
OBJECTIVE To evaluate the feasibility and toxicity of autologous haematopoietic stem cell transplantation (HSCT) for the treatment of refractory Crohn's disease (CD). DESIGN In this prospective study, patients with refractory CD suffering an aggressive disease course despite medical treatment, impaired quality of life and in whom surgery was not an acceptable option underwent HSCT. Toxicity and complications during the procedure and within the first year following transplantation were evaluated, along with the impact of the introduction of supportive measures on safety outcomes. RESULTS 26 patients were enrolled. During mobilisation, 16 patients (62%) presented febrile neutropaenia, including one bacteraemia and two septic shocks. Neutropaenia median time after mobilisation was 5 days. 5 patients withdrew from the study after mobilisation and 21 patients entered the conditioning phase. Haematopoietic recovery median time for neutrophils (>0.5×10(9)/L) was 11 days and for platelets (>20×10(9)/L) 4 days. Twenty patients (95%) suffered febrile neutropaenia and three patients (27%) presented worsening of the perianal CD activity during conditioning. Among non-infectious complications, 6 patients (28.5%) presented antithymocyte globulin reaction, 12 patients (57%) developed mucositis and 2 patients (9.5%) had haemorrhagic complications. Changes in supportive measures over the study, particularly antibiotic prophylaxis regimes during mobilisation and conditioning, markedly diminished the incidence of severe complications. During the first 12-month follow-up, viral infections were the most commonly observed complications, and one patient died due to systemic cytomegalovirus infection. CONCLUSIONS Autologous HSCT for patients with refractory CD is feasible, but extraordinary supportive measures need to be implemented. We suggest that this procedure should only be performed in highly experienced centres.

Abstract
Some patients with severe systemic lupus erythematosus do not respond to conventional immunosuppression or suffer severe side effects from such treatment. In order to explore the concept of immunoablationfollowed by haematopoieticstem cell transplantation(HSCT) or ‘rescue’, an internationalcollaboration has occurred over the past seven years. The European Group for Blood and Marrow Transplantation(EBMT) and The European League Against Rheumatism (EULAR) have analysed their collective phase I and II studies and found a remission rate (based on a reduction of the SLEDAI to < 3) in 66%, one-third of whom later relapsed to some degree. The most often used protocol was cyclophosphamide (CY) and G-CSF for mobilization and CY plus anti thymocyte globulin as conditioning. Procedure related mortality was 12% in this sick group of patients with major organ involvement. The North American, mostly single centre experience showed higher rates of remission and one procedure related death. Some relapse was also observed. Phase II studies designed to assess the role of post-HSCT maintenance therapy are being considered by the EBMT/EULAR group.

Abstract
Transplantation of hematopoietic stem and progenitor cells (HSPC), collected from peripheral blood, is the primary treatment for many hematological malignancies; however, variable collection efficacy with current protocols merits further examination into factors responsible for HSPC mobilization. HSPCs primarily reside within the bone marrow and are regulated by mesenchymal stromal cells (MSC). Exercise potently and transiently mobilizes HSPCs from the bone marrow into peripheral circulation. Thus the purpose of the present study was to evaluate potential factors in the bone marrow responsible for HSPC mobilization, investigate potential sites of HSPC homing, and assess changes in bone marrow cell populations following exercise. An acute exercise bout increased circulating HSPCs at 15 min (88%, P < 0.001) that returned to baseline at 60 min. Gene expression for HSPC homing factors (CXCL12, vascular endothelial growth factor-a, and angiopoietin-1) were increased at 15 min in skeletal muscle and HSPC content was increased in the spleen 48 h postexercise (45%, P < 0.01). Acute exercise did not alter HSPCs or MSCs quantity in the bone marrow; however, proliferation of HSPCs (40%, P < 0.001), multipotent progenitors (40%, P < 0.001), short-term hematopoietic stem cells (61%, P < 0.001), long-term hematopoietic stem cells (55%, P = 0.002), and MSCs (20%, P = 0.01) increased postexercise. Acute exercise increased the content of the mobilization agent granulocyte-colony stimulating factor, as well as stem cell factor, interleukin-3, and thrombopoeitin in conditioned media collected from bone marrow stromal cells 15 min postexercise. These findings suggest that the MSC secretome is responsible for HSPC mobilization and proliferation; concurrently, HSPCs are homing to extramedullary sites following exercise.

Abstract
Two decades ago, paediatric inflammatory bowel disease (IBD) drew only modest interest from the international paediatric community. Since then, dramatically globally increasing incidence rates have made childhood-onset IBD a priority for most paediatric gastroenterologists. The emerging pandemia of paediatric IBD has fuelled a quest to identify the recent changes in early life exposures that could explain the increasing risk for IBD amongst today's children. Treatment of children with IBD should aim for symptom control but should also target restoration of growth and prevention of pubertal delay. The paediatric IBD phenotype seems to be characterized by more extensive disease location, and some comparative studies have suggested that childhood-onset IBD also represents a more severe phenotype than the adult-onset IBD form. In this review, we analyse recent global incidence trends of paediatric IBD. We present an update on the known and suggested risk factors that could explain the emerging global epidemia of paediatric IBD. We also draw attention to differences in treatment between children and adults with IBD. Finally, we highlight latest follow-up studies that question the proposed dynamic and aggressive nature of childhood-onset IBD.

Abstract
Haematopoietic stem cell transplantation (HSCT) following intensive immune suppression has been used in >2000 patients with severe autoimmune diseases for 18 years, including 300 with SSc. The concept is to profoundly reduce the bulk of auto-aggressive immune competent cells and then rescue the patient's ablated haematopoiesis via an autologous HSCT. An early analysis of uncontrolled phase I/II data suggested that approximately one-third of these achieved a substantial improvement, with a relapse rate of 25% and a treatment-related mortality ranging from 6% to 23% across different studies. These early results led to three prospective randomized controlled trials, two of which are completed, confirming that HSCT shows clear advantages over conventional immunosuppression, but with significant toxicity. In some patients, sustained complete normalization of skin changes, reversal of positive autoantibody status and withdrawal of immunosuppressive medication were observed. These results attest to the profound effects of HSCT.

Abstract
Despite recent advances in cardiovascular medicine, ischemic diseases remain a major cause of morbidity and mortality. Although stem cell-based therapies for the treatment of ischemic diseases show great promise, limited availability of biologically functional stem cells mired the application of stem cell-based therapies. Previously, we reported a PES-nanofiber based ex vivo stem cell expansion technology, which supports expansion of human umbilical cord blood (UCB)-derived CD133(+)/CD34(+) progenitor cells ∼225 fold. Herein, we show that using similar technology and subsequent re-expansion methods, we can achieve ∼5 million-fold yields within 24 days of the initial seeding. Interestingly, stem cell phenotype was preserved during the course of the multiple expansions. The high level of the stem cell homing receptor, CXCR4 was expressed in the primary expansion cells, and was maintained throughout the course of re-expansions. In addition, re-expanded cells preserved their multi-potential differential capabilities in vitro, such as, endothelial and smooth muscle lineages. Moreover, biological functionality of the re-expanded cells was preserved and was confirmed by a murine hind limb ischemia model for revascularization. These cells could also be genetically modified for enhanced vasculogenesis. Immunohistochemical evidences support enhanced expression of angiogenic factors responsible for this enhanced neovascularization. These data further confirms that nanofiber-based ex-vivo expansion technology can generate sufficient numbers of biologically functional stem cells for potential clinical applications.

Abstract
Stem cell transplantation is a potential therapy for regenerative medicine, which aims to restore tissues damaged by trauma, aging, and diseases. Since its conception in the late 1990s, chemical biology has provided powerful and diverse small molecule tools for modulating stem cell function. Embryonic stem cells could be an ideal source for transplantation, but ethical concerns restrict their development for cell therapy. The seminal advance of induced pluripotent stem cell (iPSC) technology provided an attractive alternative to human embryonic stem cells. However, iPSCs are not yet considered an ideal stem cell source, due to limitations associated with the reprogramming process and their potential tumorigenic behavior. This is an area of research where chemical biology has made a significant contribution to facilitate the efficient production of high quality iPSCs and elucidate the biological mechanisms governing their phenotype. In this review, we summarize these advances and discuss the latest progress in developing small molecule modulators. Moreover, we also review a new trend in stem cell research, which is the direct reprogramming of readily accessible cell types into clinically useful cells, such as neurons and cardiac cells. This is a research area where chemical biology is making a pivotal contribution and illustrates the many advantages of using small molecules in stem cell research.

Abstract
A small subset of coeliac disease (CD) patients experiences persisting or recurring symptoms despite strict adherence to a gluten-free diet (GFD). When other causes of villous atrophy have been excluded, these patients are referred to as refractory celiac disease (RCD) patients. RCD can be divided in two types based on the absence (type I) or presence (type II) of an, usually clonal, intraepithelial lymphocyte population with aberrant phenotype. RCDI usually runs a benign course and may be difficult to be differentiated from uncomplicated, slow responding CD. In contrast, RCDII can be defined as low-grade intraepithelial lymphoma and frequently transforms into an aggressive enteropathy associated T-cell lymphoma with dismal prognosis. This paper describes the clinical characteristics of RCDI and RCDII, diagnostic approach, and the latest insights in treatment options.

Abstract
BACKGROUND The complexity of autoimmune diseases is reflected on their clinicopathological heterogeneity and the failure to find treatments that cure them after over a century of research. Conventional treatments help ameliorate disease activity but they treat the symptoms whereas the diseases remain incurable in the vast majority of patients. OBJECTIVE To confront diseases of such nature it is essential to discover therapeutics that will lead to the induction of tolerance or the specific deletion of autoreactive lymphocytes. Current basic and clinical research strategies focus on the better identification of self-antigens, the induction of T regulatory cells that can suppress autoreactive cell activities or, more radically, the 'reformatting' of the immune system through hematopoietic stem cell transplantation (HSCT). METHODS We analyzed literature on autoimmune disease therapeutics, focusing on new antigens that may arise from post-translational modifications of common proteins and, also, the area of HSCT. RESULTS/CONCLUSIONS With the recent discovery that citrullination of self-epitopes may be a major pathogenic mechanism for, at least, certain types of autoimmune diseases, it becomes apparent that potentially any self-antigen in the body can be a target of an autoimmune attack. In addition, although the available data on HSCT applied to patients suffering from severe refractory autoimmune diseases do not allow for the determination of the efficacy of the various methods employed to re-educate the immune system, they contribute to our understanding of disease pathogenesis and the improvement on the therapeutic approaches.

Abstract
Systemic sclerosis or scleroderma (SSc) is an heterogeneous disease involving the connective tissue and the microvasculature with fibrosis and vascular occlusion. It is difficult to define refractory SSc once it is itself a paradigm of a refractory condition: there is no evidence of when to act to stop the progression to fibrosis and irreversible microvascular damage. There is no definition of refractory disease in SSc and to propose a definition we used mainly the Medsger severity index and the EULAR 2009 treatment recommendations from the skin to the heart through peripheral vascular, musculoskeletal, gastrointestinal, renal, pulmonary hypertension and interstitial lung disease. We used some clinical setting reflecting the different reasoning when there is probable refractory disease and finally we briefly pointed out some available treatment options to refractory disease. With this reflection, we would like to open paths to a broader discussion.

Abstract
The term 'autoimmune diseases' encompasses a spectrum of diseases whose clinical manifestations and, possibly, biological features vary widely. The results of conventional treatment are considered unsatisfactory in aggressive forms, with subsets of patients having short life expectancies. Relying on wide experimental evidence and more feeble clinical data, some research groups have used autologous hematopoietic stem cell transplantation (HSCT) in the most disabling autoimmune diseases with the aim of resetting the patient's immune system. Immunoablative conditioning regimens are preferred over their myeloablative counterparts, and some form of in vivo and/or ex vivo T-cell depletion is generally adopted. Despite 15 years' experience, published controlled clinical trials are still lacking, with the evidence so far available coming from pilot studies and registry surveys. In multiple sclerosis, clinical improvement, or at least lasting disease stabilization, can be achieved in the majority of the patients; nevertheless, the worst results are observed in patients with progressive disease, where no benefit can be expected from conventional therapy. Concerning rheumatologic diseases, wide experience has been acquired in systemic sclerosis, with long-term improvements in cutaneous disease being frequently reported, although visceral involvement remains unchanged at best. Autografting has proved to be barely effective in rheumatoid arthritis and quite toxic in juvenile idiopathic arthritis, whereas it leads to clinical remission and the reversal of visceral impairment in the majority of patients with systemic lupus erythematosus. A promising indication is Crohn's disease, in which long-term endoscopic remission is frequently observed. Growing experience with autologous HCST in autoimmune diseases has progressively reduced concerns about transplant-related mortality and secondary myelodysplasia/leukemia. Therefore, a sustained complete remission seems to be within the reach of autografting in some autoimmune diseases; in others, the indications, risks and benefits of autografting need to be better defined. Consequently, the search for new drugs should also be encouraged.

Abstract
We report a case of 64-year-old patient with pure red cell aplasia (PRCA) who was intolerant of conventional immunosuppressive therapies but achieved a complete long-term remission following autologous hematologic stem cell transplant (HSCT). The patient was initially treated with high-dose prednisone, cyclophosphamide, cyclosporine, antithymocyte globulin, and then rituximab. With the exception of rituximab, all of the above regimens achieved a transient response. However, because of the persistent requirement for red blood cell transfusions and intolerance to the multiple immunosuppressive therapies, autologous HSCT was eventually performed. The patient remains in complete remission and on no other therapy for 36 months following the autologous HSCT.

Abstract
Over the last decade, hematopoietic stem cells transplantation (HSCT) has been increasingly used in the treatment of severe progressive autoimmune diseases. We report a retrospective survey of 183 multiple sclerosis (MS) patients, recorded in the database of the European Blood and Marrow Transplantation Group (EBMT). Transplant data were available from 178 patients who received an autologous graft. Overall, transplant related mortality (TRM) was 5.3% and was restricted to the period 1995-2000, with no further TRM reported since then. Busulphan-based regimens were significantly associated with TRM. Clinical status at the time of transplant and transplant techniques showed some correlations with toxicity. No toxic deaths were reported among the 53 patients treated with the BEAM (carmustine, etoposide, cytosine-arabinoside, melphalan)/antithymocyte globulin (ATG) regimen without graft manipulation, irrespective of their clinical condition at the time of the transplant. Improvement or stabilization of neurological conditions occurred in 63% of patients at a median follow-up of 41.7 months, and was not associated with the intensity of the conditioning regimen. In this large series, HSCT was shown as a promising procedure to slow down progression in a subset of patients affected by severe, progressive MS; the safety and feasibility of the procedure can be significantly improved by appropriate patient selection and choice of transplant regimen.

Abstract
Autologous haematopoietic stem cell transplantation has become an accepted powerful therapeutic procedure for patients with severe, intractable SLE. Here we describe a 26-year old patient with stage IV-G diffuse global proliferative lupus nephritis and refractory nephrotic syndrome who responded to autologous peripheral stem cell transplantation (ASCT) after two mobilization procedures. Five years later the patient is in complete clinical and immunologic remission. The indications for ASCT and its mechanism of action are briefly discussed.

Abstract
PURPOSE Cyclophosphamide in monthly intravenous bolus is used to treat severe forms of systemic sclerosis with pulmonary involvement. Since 1996, cyclophosphamide therapeutic intensification with autologous haematopoietic stem cells transplantation allowed significant improvement in skin and functional scores in severe systemic sclerosis. Cyclophosphamide potential cardiotoxicity in this setting has been questioned. METHODS To analyse cyclophosphamide potential cardiopulmonary toxicity (as graded with WHO classification), we retrospectively studied all severe systemic sclerosis patients treated with cyclophosphamide either during autologous haematopoietic stem cells transplantation procedure (group A) or intravenous cyclophosphamide (group B) recruited in 7 French centers volunteers for the study. Parameters to evaluate heart and lung functions at inclusion, then at last follow-up between 6 and 12 months after start of treatment, were compared using the Mann-Whitney test. RESULTS (Mean+/-standard deviation): Groups A (N=14) and B (N=13) were similar at the beginning of the study in terms of skin, renal, heart and lung involvement. Cyclophosphamide total dose (/m(2)) received in group A was superior (P=0.02) to the one in group B. After respective follow-up of 10+/-2.8 (group A) and 9.9+/-2.7 (group B) months, cyclophosphamide cardio toxicity (group A: N=3; group B: N=2), evolution of the left ventricular ejection fraction and arterial and pulmonary pressures did not differ in the two groups. CONCLUSION In spite of higher cyclophosphamide doses during autologous haematopoietic stem cells transplantation than bolus treatment, cardiopulmonary toxicity appeared not increased. The ongoing European ASTIS trial will compare the respective benefits of these 2 cyclophosphamide regimens in severe Systemic sclerosis.

Abstract
The potential of haemopoietic stem cell transplantation (HSCT) for the treatment of autoimmune and inflammatory diseases was originally supported by almost three decades of animal experiments and by the serendipitous remissions of autoimmune disease observed in patients undergoing transplantation for haematological disorders. Improved safety of both autologous and allogeneic HSCT over the last decade has been followed by increasing acceptance of HSCT as an experimental treatment for severe autoimmune diseases that are resistant to conventional treatment. International databases have collated over 700 procedures performed specifically for a variety of autoimmune diseases. Phase III clinical trials are in progress for some diseases. This review provides a comprehensive update on the efficacy and toxicity of HSCT in severe autoimmune disease. Future directions in the context of other evolving therapies are discussed.

Abstract
Cyclophosphamide remains the 'gold standard' treatment for severe organ threatening systemic lupus erythematosus (SLE), especially renal and central nervous system lupus. Intravenous and oral cyclophosphamide have been compared, retrospectively, with similar two year remission rates of 73% and 90%. In a meta-analysis, intravenous cyclophosphamide with oral prednisone is more effective than oral prednisone alone. The efficacy of cyclophosphamide in lupus nephritis has been proven in multiple clinical trials, but efficacy has to be balanced with toxicity, including infection, gonadal failure, and malignancy. Although the continued use ofcyclophosphamide for renal lupus has been challenged by a recent trial of mycophenolate mofetil, and may be challenged in the future by planned trials of biologics, it continues to be widely used. This review will touch on the traditional intravenous 'pulse' cyclophosphamide regimen, consider its toxicity, and contrast it with newer approaches to cyclophosphamide.

Abstract
OBJECTIVE To evaluate the safety and efficacy of autologous stem cell transplantation (ASCT) for refractory juvenile idiopathic arthritis (JIA). DESIGN Retrospective analysis of follow up data on 34 children with JIA who were treated with ASCT in nine different European transplant centres. Rheumatological evaluation employed a modified set of core criteria. Immunological reconstitution and infectious complications were monitored at three month intervals after transplantation. RESULTS Clinical follow up ranged from 12 to 60 months. Eighteen of the 34 patients (53%) with a follow up of 12 to 60 months achieved complete drug-free remission. Seven of these patients had previously failed treatment with anti-TNF. Six of the 34 patients (18%) showed a partial response (ranging from 30% to 70% improvement) and seven (21%) were resistant to ASCT. Infectious complications were common. There were three cases of transplant related mortality (9%) and two of disease related mortality (6%). CONCLUSIONS ASCT in severely ill patients with JIA induces a drug-free remission of the disease and a profound increase in general wellbeing in a substantial proportion of patients, but the procedure carries a significant mortality risk. The following adjustments are proposed for future protocols: (1) elimination of total body irradiation from the conditioning regimen; (2) prophylactic administration of antiviral drugs and intravenous immunoglobulins until there is a normal CD4+ T cell count.

Abstract
Pure red cell aplasia (PRCA) is characterized by a selective marrow aplasia of the erythroid compartment. Immunosuppressive therapy achieves good results in about 25% of cases, but relapses are frequent. Autologous or allogeneic haematopoietic stem cell transplantation (HSCT) may be valuable in selected patients. Here, we report details of a 29-year-old woman treated successfully by donor lymphocyte infusions (DLIs) following allogeneic HSCT for acquired refractory relapsed PRCA. The nonmyeloablative conditioning regimen consisted of cyclophosphamide 60 mg/kg/day for 2 days and fludarabine 30 mg/m(2) daily for 4 days. Haematopoiesis was still completely 'recipient' 1 month after allo-HSCT, but progressed to full donor engraftment after three doses of 'escalating' DLI. The possible role of a graft-versus-autoimmunity effect induced by allogeneic HSCT followed by DLI infusions in the treatment of the disease is discussed.

Abstract
Systemic lupus erythematosus (SLE) is an immune-mediated disease that is responsive to suppression or modulation of the immune system. Patients with SLE who experience persistent multiorgan dysfunction, despite standard doses of intravenous cyclophosphamide (Cy), represent a subset of patients at high risk of early death. We investigated the efficacy and toxicity of high-dose immunosuppression and autologous hematopoietic stem cell transplantation (SCT) to treat such patients. Six patients (all female, age 15-29 years) with severe refractory SLE were enrolled in the clinic of our institution from 1998 to 2003. All patients were seriously ill, with SLE disease activity indices (SLEDAI) of 6-30, including two cases with central nervous system lupus, one case with lung vasculitis, and three cases with nephritis and nephrotic syndrome. All patients were registered in the European Group for Blood and Marrow Transplantation (EBMT)/European League Against Rheumatism (EULAR) database. Previous immunosuppression included pulse Cy intravenous, prednisolone (standard doses and pulse therapy), oral Cy and azathioprine, with little or no effect on disease progression. Autologous hemopoietic stem cells were collected from bone marrow (n = 4) or mobilized from peripheral blood with Cy and granulocyte colony-stimulating factor (G-CSF) (n = 2). Pre-transplant conditioning regimens included BEAM +/- ATG (n = 2), melphalan 140 mg/m2 + etoposid 1600 mg/m2 (n = 2) and Cy 200 mg/kg +/- ATG (n = 2). Median time to an absolute neutrophil count (ANC) greater than 0.5 x 10(9)/L and platelet count greater than 50 x 10(9)/L was 13 and 15 days, respectively. Three patients died on days 11, 22 and 63 due to transplant-related complications. The follow-up is now 60 and six months for two patients (complete remission), and 42 months for one other patient (partial response). All patients had experienced multiple and severe episodes of infections pre-SCT and long-term history of corticosteroid therapy (3-14 years). We conclude that achievement of prolonged, corticosteroid-free remissions is a reality. Judicious selection of patients earlier in disease or in remission, but with a high risk of relapse or further progression, will diminish transplantation-related mortality.

Abstract
Multiple sclerosis is a relatively common and seriously disabling disease of autoimmune pathogenesis, for which there is currently no cure. Available therapies include immunomodulating agents and standard-dose immunosuppressants, which may be helpful but are not curative. Recently, studies in animal models have indicated that control of autoimmune disease can be obtained by high-dose immunosuppression followed by hematopoietic stem cell transplantation (rescue). Autologous transplants for severe and refractory multiple sclerosis were proposed in 1997 and have been performed ever since in selected patients and in the context of phase I/II trials. To date, more than 200 patients have been treated worldwide, and similar results were obtained in different centers: high-dose therapy suppresses inflammation in the brain to a degree superior to any other conventional therapy and seems to delay significantly clinical disease progression. There is, however, a procedure-related mortality risk of 1.5-5%, requiring careful patient selection before transplant. The treatment should be reserved for patients having high chance of response, i.e., young patients with low disability scores but rapidly progressing disease, having inflammatory rather than neurodegenerative changes in the central nervous system. The mechanism of action of transplantation is unclear. The initial concept of immune ablation by high-dose therapy and reconstitution of normal immunity from transplant-derived lymphocyte progenitors has given way to the concept of "resetting" the immune system and of bringing the disease to a lower level of activity. One could also speculate on a tissue repair effect, given the ability of human hematopoietic stem cells to migrate also into the central nervous system. The clinical effect of transplantation remains to be demonstrated in a randomized study. The Autoimmune Disease Working Party of the European Group for Blood and Marrow Transplantation has launched such a trial, comparing transplantation to the currently best available therapy, i.e., mitoxantrone, and in about 5 years we should know whether transplantation offers more than the benefit of a transient immunosuppressive effect.

Abstract
OBJECTIVE To analyse the durability of the responses after haematopoietic stem cell transplantation (HSCT) for severe systemic sclerosis (SSc) and determine whether the high transplant related mortality (TRM) improved with experience. This EBMT/EULAR report describes the longer outcome of patients originally described in addition to newly recruited cases. METHODS Only patients with SSc, treated by HSCT in European phase I-II studies from 1996 up to 2002, with more than 6 months of follow up were included. Transplant regimens were according to the international consensus statements. Repeated evaluations analysed complete, partial, or non-response and the probability of disease progression and survival after HSCT (Kaplan-Meier). RESULTS Given as median (range). Among 57 patients aged 40 (9.1-68.7) years the skin scores improved at 6 (n = 37 patients), 12 (n = 30), 24 (n = 19), and 36 (n = 10) months after HSCT (p<0.005). After 22.9 (4.5-81.1) months, partial (n = 32) or complete response (n = 14) was seen in 92% and non-response in 8% (n = 4) of 50 observed cases. 35% of the patients with initial partial (n = 13/32) or complete response (n = 3/14) relapsed within 10 (2.2-48.7) months after HSCT. The TRM was 8.7% (n = 5/57). Deaths related to progression accounted for 14% (n = 8/57) of the 23% (n = 13/57) total mortality rate. At 5 years, progression probability was 48% (95% CI 28 to 68) and the projected survival was 72% (95% CI 59 to 75). CONCLUSION This EBMT/EULAR report showed that response in two thirds of the patients after HSCT was durable with an acceptable TRM. Based on these results prospective, randomised trials are proceeding.

Abstract
Based on the encouraging results of transplantation in animals with experimental autoimmune encephalomyelitis (EAE), small-scale phase I/II trials of autologous hematopoietic stem cell transplantation (autoHSCT) were initiated in 1995 for the treatment of severe cases of multiple sclerosis (MS). More than 200 patients with treatment-resistant multiple sclerosis have been transplanted so far, mainly in Europe and the USA. The results of these studies appear promising in terms of impact on MRI disease parameters and, to a lesser extent, clinical stabilization or even improvement. Despite concerns raised by the morbidity and mortality noted in the initial pilot studies, a controlled, randomized, phase III trial of autoHSCT against the best currently available treatment, i.e., mitoxantrone, seems justified and is under way.

Abstract
This study describes the outcome of patients receiving haematopoietic stem cell transplantation (HSCT) to treat severe refractory autoimmune cytopenia. The registry of the European Group of Blood and Marrow Transplantation holds data on 36 patients receiving 38 transplants, the first transplant was autologous for 27 and allogeneic for nine patients. Patients had autoimmune haemolytic anaemia (autologous: 5; allogeneic: 2), Evans's syndrome (autologous: 2; allogeneic: 5); immune thrombocytopenia (autologous: 12), pure red cell aplasia (autologous: 4; allogeneic: 1), pure white cell aplasia (autologous: 1; allogeneic 1), or thrombotic thrombocytopenic purpura (autologous: 3). Patients had longstanding disease having failed multiple prior treatments. Among 26 evaluable patients mobilized for autologous HSCT, three died of treatment-related causes, one died of disease progression, seven were non-responders, six patients had transient responses and nine had continuous partial or complete remission. Of the seven evaluable patients receiving allogeneic HSCT, one died of treatment-related complications, one with transient response died of progressive disease and five had a continuous response. Autologous and allogeneic HSCT may induce a response in a subset of patients with autoimmune cytopenia of long duration albeit at the price of considerable toxicity.

Abstract
This review summarizes data on haematopoietic stem cell transplantation (HSCT) to treat severe, refractory, haematological autoimmune cytopenia. A phase II study by the National Institutes of Health of the USA has presented data on autologous HSCT in 14 patients with immune thrombocytopenia or Evans' syndrome, with no early deaths and a response rate of 57%. The registry of the European Group for Blood and Marrow Transplantation holds data on 38 transplants, autologous for 27 and allogeneic for 9 patients. The disease entities and regimens used were more heterogeneous. The conditions encountered were autoimmune haemolytic anaemia, Evans' syndrome, immune thrombocytopenia, pure red cell aplasia, pure white cell aplasia and thrombotic thrombocytopenic purpura. Patients had long-standing disease, having failed multiple prior treatments. Among 26 evaluable patients mobilized for autologous HSCT, 3 died of treatment-related causes, 1 died of disease progression, 7 were non-responders, 6 patients had transient responses, and 9 had sustained partial or complete remission. Of the 7 evaluable patients receiving allogeneic HSCT, 1 died of treatment-related complications, 1 with a transient response died of progressive disease, and 5 showed a sustained response. Autologous and allogeneic HSCT may induce a response in a considerable proportion of patients with autoimmune cytopenia of long duration.

Abstract
We have evaluated bone marrow morphology, percentage of bone marrow CD34(+) cells, proliferative activity of bone marrow precursors, clonogenic assay (BFU-E and CFU-GM) in short-term bone marrow cultures, and bone marrow cell apoptosis, together with serum TNF-alpha and IL-6, in 16 chronic, refractory RA patients, as well as in five healthy controls. Of 16 RA patients (68.7%), 11 showed a reduced bone marrow cellularity, while it was normal in all the controls. In RA patients, the median percentage of CD34(+) bone marrow cells, the median percentage of proliferating bone marrow myeloid precursors, and the median number of both BFU-E and CFU-GM colonies were significantly lower than observed in the controls. As far as TNF-alpha and IL-6 titers is concerned, the latter did not significantly differ from controls' values, while TNF-alpha titers were significantly lower in healthy controls. Finally, the median apoptotic index of early bone marrow myeloid cells of RA patients was significantly higher compared with controls. These observations may identify the biological risk factors for impaired mobilization and/or engraftment when RA patients are candidates for autologous hematopoietic stem cell grafting.

Abstract
Experimental and clinical observations have indicated that high-dose immunosuppression followed by autologous stem cell transplantation (ASCT) can induce remissions in severe, refractory, autoimmune diseases including multiple sclerosis (MS), a T cell-mediated autoimmune disorder against CNS myelin components, causing severe chronic disability. Control of the disease is unsatisfactory in most of the patients, especially those with rapidly evolving relapsing-remitting course and those with chronic progressive disease. The rationale for treating autoimmune diseases with ASCT is based on the immunosuppressive and immunomodulating effects of ASCT which may shift the immunological balance towards disease quiescence, a hypothesis supported by the results of ASCT in animal models of MS and by clinical observations in MS patients transplanted for concurrent malignancies. A number of phase I-II studies of ASCT in patients with active MS, conducted worldwide since 1995, and a comprehensive analysis of 85 patients, recently reported by the European Group for Blood and Marrow Transplantation (EBMT), have shown the feasibility of the method, a prominent anti-inflammatory effect on magnetic resonance imaging (MRI) disease, and a possible clinical benefit for active and refractory cases. The impact on MRI disease parameters appears superior with ASCT than with conventional therapies but the clinical results, in terms of stabilization of disease and prevention of disability, need to be validated in prospective, controlled trials. The procedure is also associated with a transplant-related mortality risk, of about 5% in high-risk cases, i.e., in older patients, those with high disability scores, those receiving strong myeloablative conditioning regimens and those undergoing intensive in vivo or ex vivo T cell-depletion. Therefore, it could be recommended for the treatment of a chronic, non-lethal, disease like MS only if it proved superior to standard therapies. A randomized trial is now launched by the EBMT to compare ASCT to mitoxantrone, currently regarded as one of the best available treatments, in properly selected patients having high chance of response at minimal mortality risk.

Abstract
Since 1997, autologous stem cell transplantation (ASCT) had been applied to more than 40 children with polyarticular or systemic juvenile idiopathic arthritis (JIA). For this review, results of the follow-up are available from 25 children with systemic JIA and six with polyarticular JIA that were reported in detail from eight different pediatric European transplant centers. Before ASCT all children had progressive disease despite the use of corticosteroids, methotrexate (MTX) up to 1 mg/kg/week, cyclosporin (2.5 mg/kg/day) and/or anti-TNFalpha therapy. The clinical follow-up of these children ranges from 8 to 60 months (median 33 months).

Abstract
As many as 40% of patients with Wiskott-Aldrich syndrome may eventually suffer from an autoimmune disorder, with an increased chance of developing a malignancy. Vasculitides and autoimmune hemolytic anemia are the two most common autoimmune manifestations and often cause considerable morbidity and mortality, because they may require treatment with bone marrow transplantation. Insights into the mechanisms of autoimmunity have provided clues to the pathogenesis of these disorders in Wiskott-Aldrich syndrome. Chronic inflammation, interleukin-2 deficiency, and increased apoptosis may all play a possible role in the loss of peripheral tolerance to self-antigens in this disease. This article reviews the manifestations and consequences of autoimmunity in Wiskott-Aldrich syndrome, its possible mechanisms, and available treatments.

Abstract
Hematopoietic stem cell transplantation (HSCT) is being increasingly utilized for the treatment of a whole spectrum of severe autoimmune diseases refractory to conventional therapy. Although allogeneic HSCT has been followed by durable complete remission in a restricted number of patients with coincidental disease, the autologous procedure is generally preferred because of its lesser toxicity. Most autoimmune diseases are the consequence of a multistep process, mainly originating from the interplay of genetic, environmental, and hormonal factors. It has been postulated that if immunosuppressive regimens can eliminate or effectively reduce the level of autoreactive T and B cells, then regeneration of de novo immunity even in the autologous setting may bypass the initial breakdown of self-tolerance and ensure prolonged disease remission. As mentioned in a recent review of this field, protocol design including conditioning regimen, patient selection, stem cell source and final outcome are likely to be disease-specific. The following is a summary of the 2002 International Bone Marrow Transplantation Registry/American Society of Blood and Bone Marrow Transplantation (IBMTR/ASBMT) satellite symposium in Orlando, Florida on 24 February 2002 on 'Expanding the Promise of Hematopoietic Stem Cell Transplantation in Autoimmune Diseases'.

Abstract
Cytotoxic therapy is a cornerstone for patients with severe systemic lupus erythematosus (SLE). High-dose cyclophosphamide, 200 mg/kg, can induce a complete remission without the need for stem cell rescue in patients with autoimmune illnesses. Here we report on our first four patients treated for severe SLE with this treatment approach. Patients received cyclophosphamide, 200 mg/kg, divided over 4 days. Starting day 10, patients received filgrastim, 5 micrograms/kg/day, until their absolute neutrophil count (ANC) rose to 10.0 x 10(9)/l for two consecutive days. Disease activity as evaluated by scores from the Systemic Lupus Activity Measure-2, the SLE Disease Activity Index and the Responder Index for Lupus Erythematosus were completed before and after high-dose therapy. Before high-dose cyclophosphamide, SLE disease duration ranged from 8 to 21 (mean 12.5) years. Their average disease activity measured by SLAM-2 and SLEDAI was 15.5 (range 11-19) and 23.25 (range 20-26), respectively. At a median of 22 (range 12-39) months of follow-up, mean disease activity measured by SLAM-2 and SLEDAI decreased to 6.25 and 7.75, respectively. All patients experienced febrile neutropenia. No long-term morbidities or mortalities were observed. High dose cyclophosphamide is a therapy capable of decreasing disease severity in poor prognosis SLE patients. Future study is warranted for both refractory patients as well as primary therapy for patients with moderate to severe disease presentations.
