Hematopoietic Stem Cell Transplantation for the Treatment of Autoimmune Neurological Diseases: An Update. Bioengineering (Basel) 2023; 10:bioengineering10020176.

Abstract
Over the last two decades, haematopoietic stem cell transplantation (HSCT) has been explored as a potential therapeutic strategy for autoimmune diseases refractory to conventional treatments, including neurological disorders. Although both autologous (AHSCT) and allogeneic HSCT (allo-HSCT) were investigated, AHSCT was preferentially developed due to a more favourable safety profile compared to allo-HSCT. Multiple sclerosis (MS) represents the most frequent neurological indication for AHSCT, but increasing evidence on the potential effectiveness of transplant in other autoimmune neurological diseases is emerging, although with a risk-benefit ratio overall more uncertain than in MS. In the present work, the rationale for the use of HSCT in neurological diseases and the experimental models that prompted its clinical application will be briefly covered. Case series and prospective studies exploring the use of HSCT in autoimmune diseases other than MS will be discussed, covering both frequent and rare neurological disorders such as myasthenia gravis, myopathies, and stiff-person syndrome. Finally, an updated summary of ongoing and future studies focusing on this issue will be provided.

Abstract
Type 1 diabetes mellitus is a chronic disease that results from the autoimmune response against pancreatic insulin producing β cells. Apart of several insulin regimens, since the decade of 80s various immunomodulatory regimens were tested aiming at blocking some steps of the autoimmune process against β cell mass and at promoting β cell preservation. In the last years, some independent research groups tried to cure type 1 diabetes with an "immunologic reset" provided by autologous hematopoietic stem cell transplantation in newly diagnosed patients, and the majority of patients became free form insulin with increasing levels of C-peptide along the time. In this review, we discuss the biology of hematopoietic stem cells and the possible advantages and disadvantages related to the high dose immunosuppression followed by autologous hematopoietic stem cell transplantation.

Abstract
Maintenance of T cell memory in autoimmune disease may be complex because the unending renewable supply of self provides an inherent high antigen load that effectively precludes clearance, and because the broad array of potential immunogenic targets provides extensive self-recognition plasticity. Autoimmunity is characterized by a dynamic self-recognition process in which the primary autoreactivity initiating disease is soon followed and often displaced by secondary neoautoreactivities, or epitope spreading, that emerge as a result of endogenous self-priming. Here we show that the autoimmune disease process involves a tertiary phase of self recognition characterized by stem cell reconstitution of autoreactive T cells that recapitulates the myelin self recognition process involved in disease initiation and spreading during experimental autoimmune encephalomyelitis (EAE). Our study indicates that sustained autoimmune memory may not simply be due to the persistence of long-lived memory T cells, but may also involve bone marrow regeneration and replacement of the autoreactive T cell repertoire.

Abstract
THE PATHOPHYSIOLOGY of most autoimmune diseases is often poorly understood. EXPERIMENTAL CONSIDERATIONS and clinical experience suggest that high doses immunoablation followed by stem cell transplantation is a therapeutic option to consider for certain severe autoimmune disorders. THE CONCEPT OF RESTORING NORMAL IMMUNE REACTIVITY must in part br true since current results of 466 transplants (445 autologous, 21 allogeneic) patients suffering from various autoimmune diseases show a beneficial outcome in approximately 2/3 of the patients. TO IMPROVE THE EFFICACY AND SAFETY OF SUCH AN AGGRESSIVE PROCEDURE in patients with potentially affected vital organs by the underlying autoimmune disease, it is especially important to follow international consensus guidelines and to centrally collect clinical data for in depth analysis in the EBMT International Stem Cell Project for Autoimmune Disease in Basel, Switzerland. PHASE III STUDIES ARE RUNNING FOR SYSTEMIC SCLEROSIS (Astis, Autologous Stem cell Transplantation International Rheumatoid Arthritis Trial) started in 2003. A STUDY PROJECT IS PLANNED FOR MULTIPLE SCLEROSIS (Astims, Autologous Stem cell Transplantation International Multiple 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
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
Autologous transplants for severe and refractory multiple sclerosis (MS) were proposed in 1997 and have been performed on about 200 selected patients worldwide. Phase I/II clinical studies have shown that high-dose immunosuppressive therapy suppresses inflammation in the CNS and may delay the progression of clinical disease. The procedure is associated with toxicity from the high-dose cytotoxic therapy and a risk of serious infections. There is a transplant-related mortality risk of 1-5%, requiring careful patient selection before transplantation. Treatment should be reserved for patients who have a significant chance of response, i.e. young patients with low disability scores but rapidly progressing disease who have inflammatory rather than neurodegenerative changes in the CNS. The long term effect of high-dose immunosuppression after transplantation on the frequency of relapse or progression of MS is unclear, but the initial concept of immune ablation by high-dose therapy and the reconstitution of normal immunity and tolerance from transplant-derived lymphocyte progenitors has given way to the concept of 'resetting' the immune system. The clinical effect of transplantation remains to be demonstrated in comparative studies.

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
Haematopoietic stem cell transplantation (HSCT) has been proposed for refractory autoimmune diseases, including systemic sclerosis (SSc). A sequential Bayesian phase I-II clinical trial was conducted in SSc patients to assess the feasibility, the tolerance and the efficacy of autologous HSCT. Peripheral blood stem cells (PBSC) were collected using cyclophosphamide (4 g/m2) and recombinant human granulocyte colony-stimulating factor (5 micro g/kg/d) and reinfused after positive CD34+ selection. Conditioning used cyclophosphamide (200 mg/kg) or melphalan (140 mg/m2) according to cardiac function. The main end-point was the failure of the procedure, defined by failure of either PBSC mobilization, CD34+ selection or intensification procedure, or by procedure-related death. Among the 12 enrolled patients, three failures occurred: one PBSC mobilization, one CD34+ selection and one CD34+ intensification. Probability of graft failure was estimated at 0.286 (95% confidence interval: 0.095-0.54). Autologous PBSC (n = 10) or bone marrow (n = 1) transplantation was actually performed in 11 patients with one procedure-related death. Median time to neutrophil (> 0.5 x 10(9)/l) and platelet (> 25 x 10(9)/l) haematopoietic reconstitution was 12 and 10 d respectively. After 18 months (range 1-26), eight out of 11 patients have shown major or partial response. Non-myeloablative conditioning, followed by a T cell-depleted autologous PBSC or bone marrow transplantation, appears feasible with low toxicity in severe SSc with short-term clinical benefits.

Abstract
OBJECTIVE Evidence from animal studies, case reports, and phase I studies suggests that hemopoietic stem cell transplantation (HSCT) can be effective in the treatment of rheumatoid arthritis (RA). It is unclear, however, if depletion of T cells in the stem cell product infused after high-dose chemotherapy is beneficial in prolonging responses by reducing the number of infused autoreactive T cells. This pilot multicenter, randomized trial was undertaken to obtain feasibility data on whether CD34 selection (as a form of T cell depletion) of an autologous stem cell graft is of benefit in the HSCT procedure in patients with severe, refractory RA. METHODS Thirty-three patients with severe RA who had been treated unsuccessfully with methotrexate and at least 1 other disease-modifying agent were enrolled in the trial. The patients received high-dose immunosuppressive treatment with 200 mg/kg cyclophosphamide followed by an infusion of autologous stem cells that were CD34 selected or unmanipulated. Safety, efficacy (based on American College of Rheumatology [ACR] response criteria), and time to recurrence of disease were assessed on a monthly basis for up to 12 months. RESULTS All patients were living at the end of the study, with no major unexpected toxicities. Overall, on an intent-to-treat basis, ACR 20% response (ACR20) was achieved in 70% of the patients. An ACR70 response was attained in 27.7% of the 18 patients who had received CD34-selected cells and 53.3% of the 15 who had received unmanipulated cells (P = 0.20). The median time to disease recurrence was 147 days in the CD34-selected cell group and 201 days in the unmanipulated cell group (P = 0.28). There was no relationship between CD4 lymphopenia and response, but 72% of rheumatoid factor (RF)-positive patients had an increase in RF titer prior to recurrence of disease. CONCLUSION HSCT can be performed safely in patients with RA, and initial results indicate significant responses in patients with severe, treatment-resistant disease. Similar outcomes were observed in patients undergoing HSCT with unmanipulated cells and those receiving CD34-selected cells. Larger studies are needed to confirm these findings.

Abstract
Based on experimental and clinical observations, high-dose immunosuppression followed by autologous transplantation may induce remissions in severe, refractory, autoimmune disorders including multiple sclerosis, a disease which, in its progressive form, does not respond to treatment. Phase I/II studies of transplantation in MS published by individual centers as well as a comprehensive analysis of the reports to the EBMT registry have shown that transplantation may positively affect MS by stabilizing the clinical condition of the patients, by improving their disability status, and by completely abrogating the inflammatory process in the brain as evidenced in magnetic resonance imaging. Other available therapies do not appear to be so efficacious as transplantation. However, the procedure is associated with a transplant-related mortality risk of about 3 to 8%. Therefore, it cannot be recommended for the treatment of a chronic, non-lethal, disease like MS unless it proves superior to standard therapies in terms of efficacy. This can be demonstrated only in a randomized trial, which is being launched by the EBMT under the name ASTIMS. It compares the BEAM regimen plus autotransplantation to mitoxantrone, which is currently regarded as one of the best available treatments, in patients with secondary progressive or rapidly evolving relapsing/remitting multiple sclerosis.

Abstract
Much progress has been made in the field of haemopoietic stem cell transplants (HSCTs) for severe autoimmune disorders. Theoretical considerations, animal data and anecdotal evidence suggested some time ago that intensive immunoablation followed by autologous HSCT could restore normal immune reactivity in patients with severe autoimmune disorders. Based on a concept statement issued in 1995, two European societies, the European League Against Rheumatism (EULAR) and the European Group for Blood and Marrow Transplantation (EBMT) began collecting phase I/II trial data in an international collaborative network. Sufficient information from more than 350 patients allows a preliminary assessment with level three evidence. Autologous HSCTs can induce remissions in all disease categories tested so far. Remissions can be transient or durable. HSCTs are associated with significant morbidity and mortality. Treatment-related mortality (TRM) is near 10% at 1 year and is associated with the intensity of the conditioning and the stage of the disease at the time of transplant. Marked interdisease differences exist. There are few data available in haematological autoimmune diseases, more in systemic sclerosis (SSc), systemic lupus erythematosus (SLE), juvenile idiopathic arthritis (JIA) and multiple sclerosis (MS). Patient selection has been recognized as a crucial element from the phase I-II trials. Patients with advanced disease, severely compromised organ function or irreversible organ damage should not be considered as candidates for HSCT. Prospective randomized studies should now determine the value of HSCT compared to standard therapy. Such trials are ongoing for patients with systemic sclerosis (ASTIS trial--Autologous Stem Cell Transplantation International Scleroderma Trial) or are planned for patients with multiple sclerosis (ASTIMS trial--Autologous Stem Cell Transplantation International Multiple Sclerosis Trial) and rheumatoid arthritis (ASTIRA trial--Autologous Stem Cell Transplantation International Rheumatoid Arthritis Trial). More phase II data are needed for other indications such as SLE and JIA.

Abstract
Animal models of autoimmune disease and case reports of patients with these diseases who have been involved in bone marrow transplants have provided important data implicating the haemopoietic stem cell in rheumatic disease pathogenesis. Animal and human examples exist for both cure and transfer of rheumatoid arthritis, systemic lupus erythematosus (SLE) and other organ-specific diseases using allogeneic haemopoietic stem cell transplantation. This would suggest that the stem cell in these diseases is abnormal and could be cured by replacement of a normal stem cell although more in vitro data are required in this area. Given the morbidity and increased mortality in some patients with severe autoimmune diseases and the increasing safety of autologous haemopoietic stem cell transplantation (HSCT), pilot studies have been conducted using HSCT in rheumatic diseases. It is still unclear whether an autologous graft will cure these diseases but significant remissions have been obtained which have provided important data for the design of randomized trials of HSCT versus more conventional therapy. Several trials are now open to accrual under the auspices of the European Bone Marrow Transplant Group/European League Against Rheumatism (EBMT/EULAR) registry. Future clinical and laboratory research will need to document the abnormalities of the stem cell of a rheumatic patient because new therapies based on gene therapy or stem cell differentiation could be apllied to these diseases. With increasing safety of allogeneic HSCT it is not unreasonable to predict cure of some rheumatic diseases in the near future.

Abstract
The prevalence of autoimmune diseases (ADs) in Western countries is estimated to be from 3-7%, and the treatment of severe, relapsing/refractory cases is still not satisfactory. The concept of utilizing intense immunosuppression followed by allogeneic or even autologous hemolymphopoietic stem cells (HSCs) to treat AD is based on encouraging results in experimental animals and from serendipitous cases of patients with both ADs and malignancies who were allotransplanted for the latter. However, rare unexpected relapses despite donor immune engraftment have been reported following HSC transplantation for AD. Autologous transplantation is a more feasible procedure with lower toxicity than allogeneic transplantation. This article analyzes the experimental basis for stem cell transplantation in AD and discusses the most important clinical results of both allogeneic and autologous HSC transplants.

Abstract
High-dose immunoablative chemotherapy with autologous haematopoietic cell support might be beneficial in the treatment of intractable forms of MS. We mobilised PBPC in 11 patients with secondary progressive MS and finally eight patients were grafted after high-dose BEAM chemotherapy with either in vitro or in vivo T cell depletion. Median EDSS and SNRS scores at the time of inclusion were 6.5 (6.5-7.5) and 56 (44-65), respectively. PBPC mobilisation was safe with no serious adverse effects, and without significant aggravation of disability. One patient improved significantly (by 1.0 point on EDSS) after the mobilisation. Two mobilisation failures were observed. No life-threatening events occurred during the transplantation. All grafted patients, except one, at least stabilised their disability status. One patient improved significantly (by 1.5 points on EDSS), two patients improved slightly (by 0.5 points on EDSS), one patient worsened by 1.0 point on the EDSS in 10 months. Improvement occurred with a delay of 2-4 months. Median EDSS and SNRS of grafted patients at the last follow up were 6.5 (5.5-8.5) and 64 (39-73), respectively with median follow-up of 8.5 months. Further follow-up is needed to determine the disease course after complete immune reconstitution. Bone Marrow Transplantation (2000) 25, 525-531.

Abstract
Treatment of rats suffering from florid chronic progressive systemic arthritis or from chronic remitting/relapsing encephalomyelitis with autologous bone marrow transplantation (BMT) is highly effective. This finding was unexpected as the genotype of the bone marrow largely determines the susceptibility of both spontaneous and induced autoimmune diseases in rodents. The success of autologous stem-cell transplantation depends on the completeness of eradication of the effectors of autoimmune disease, in other words activated and memory T lymphocytes. The reviewed experimental data, when translated to the clinic, indicate that the patients should be subjected to a conditioning regimen that induces maximal lymphoablation and that the autologous transplant has to be T-cell depleted.

Abstract
Based on the good results of experimental transplantation in animal models of multiple sclerosis and of other autoimmune diseases, we have treated 24 patients suffering from chronic progressive multiple sclerosis with high-dose chemotherapy (BEAM regimen) followed by autologous blood stem cell rescue and antithymocyte globulin. Blood stem cells were mobilised with cyclophosphamide at 4g/m2 and G- (or GM-) CSF. In 9 cases, additional CD34+ cell-selection of the graft was performed. Here we update previously published results of this novel treatment, mainly with regard to clinical efficacy, as the median follow-up time has reached 40 months (range, 21-51). Infections were the principal toxicity early after the procedure, with death of a patient from aspergillosis 65 days post stem cell infusion. No serious late events occurred apart from a case of autoimmune thyroiditis that developed 11 months after transplant in a patient who had received a CD34+ cell-depleted graft. Mild and transient neurotoxicity was observed in 10 patients (42%), most probably associated with fever and infections. Eighteen patients (18/23; 78%) responded to the treatment, i.e., they were improved or stabilized, while five patients progressed, of which 4 had primary progressive disease. Of those improved or stabilised (18), 9 patients have maintained stable condition whereas 9 developed relapses or they slowly resumed progression, although their disability scores have not gotten worse than they were before transplantation. The probability of progression-free survival (compared to entry status) at 3 years is 92% for patients with secondary progressive disease and 39% for the primary progressive type. CD34+ cell-selection did not seem to yield better results except for a delay in progression or in relapse after transplantation. These results appear better than those achieved by any other treatment of progressive multiple sclerosis, including beta-interferon, but they need to be confirmed by other open or controlled studies in view of the well-known difficulty of judging objectively the effect of a treatment in patients with this disease.

Abstract
A review of the experiments with animal models of autoimmune disease (AID) that have provided the rationale for the present clinical investigations on the use of autologous stem cells for treating patients with severe refractory AID. The various types of AID in laboratory animals and the recognition of the key-role of hematopoietic stem cells (HSC) in AID are discussed. Two animal models were employed for translational research on autologous bone marrow transplantation (BMT): adjuvant arthritis (AA) as model for rheumatoid arthritis (RA) and experimental allergic encephalomyelitis (EAE) as model for multiple sclerosis (MS). The principal aspects of the treatment, i.e., conditioning agents and doses and T cell depletion of the autograft, were investigated in relation to remission induction and the incidence of relapses.

Abstract
Autologous hemopoietic stem cell transplantation (HSCT) for autoimmune disease has increased lately. Insights into response to immunoablation is found in animal experiments and reports on patients receiving HSCT for concomitant malignancy. Early phase II studies and case reports of HSCT in patients with multiple sclerosis, systemic sclerosis, lupus erythematosus, rheumatoid arthritis, juvenile chronic arthritis and idiopathic thrombocytopenic purpura have been published. Dramatic responses or disease stabilization have been observed in some, but failures and disease relapses, toxic and infectious complications have been observed in others. Whether this treatment can induce true peripheral immunologic tolerance, and which been observed if any patients will benefit long-term from HSCT, remains to be determined.

Abstract
The concept of using hematopoietic stem cell transplantation to treat patients with autoimmune disease was first provided by animal studies and anecdotal case reports. Advances over recent years in autologous hematopoietic stem cell transplantation, most notably cytokine-mobilized peripheral blood stem cells, have been followed by its specific use to treat severe autoimmune and inflammatory diseases. Guidelines have been published, and, by March 1999, 150 cases were registered with the International Autoimmune Disease Stem Cell Project Database. This review summarizes the literature published with respect to inflammatory rheumatic disease over the past few years and discusses future directions aimed at refining this intensive approach.
