Abstract
Systemic lupus erythematosus (SLE), an autoimmune disease, is among the most prevalent rheumatic autoimmune disorders. It affects autologous connective tissues caused by the breakdown of self-tolerance mechanisms. During the last two decades, stem cell therapy has been increasingly considered as a therapeutic option in various diseases, including parkinson's disease, alzheimer, stroke, spinal cord injury, multiple sclerosis, inflammatory bowel disease, liver disease, diabete, heart disease, bone disease, renal disease, respiratory diseases, and hematological abnormalities such as anemia. This is due to the unique properties of stem cells that divide and differentiate to the specialized cells in the damaged tissues. Moreover, they impose immunomodulatory properties affecting the diseases caused by immunological abnormalities such as rheumatic autoimmune disorders. In the present manuscript, efficacy of stem cell therapy with two main types of stem cells, including mesenchymal stem cell (MSC), and hematopoietic stem cells (HSC) in animal models or human patients of SLE, has been reviewed. Taken together, MSC and HSC therapies improved the disease activity, and severity in kidney, lung, liver, and bone (improvement in the clinical manifestation). In addition, a change in the immunological parameters occurred (improvement in immunological parameters). The level of autoantibodies, including antinuclear antibody (ANA), and anti-double-stranded deoxyribonucleic acid antibodies (dsDNA Abs) reduced. A conversion of Th1/Th2 ratio (in favor of Th2), and Th17/Treg (in favor of Treg) was also detected. In spite of many advantages of MSC and HSC transplantations, including efficacy, safety, and increased survival rate of SLE patients, some complications, including recurrence of the disease, occurrence of infections, and secondary autoimmune diseases (SAD) were observed after transplantation that should be addressed in the next studies.

Abstract
The recent introduction of biologic and targeted synthetic disease-modifying drugs has led to more specificity in the treatment of autoimmune diseases; however, they require continuous or intermittent administration, are associated with cumulative risks for side effects, result in high costs and provide no cure. In contrast, high-dose chemotherapy followed by transplantation of autologous hematopoietic stem cells (AHSCT) has been demonstrated to induce clinical remission in various autoimmune diseases that can persist over many years without continued maintenance therapy. The principle behind AHSCT is an elimination of important components of the autoreactive immunological memory with subsequent regeneration of the complete immune system. Several studies have indicated that such an immune reset is associated with fundamental changes in the immune repertoire leading to an induction of tolerance against self-antigens. This article presents the current indications of AHSCT for autoimmune diseases based on the registry data of the European Society of Blood and Marrow Transplantation (EBMT) and discusses the results from mechanistic studies, which provide detailed insights into the mode of action of this treatment.

Abstract
Despite advances in treating Systemic lupus erythematosus (SLE), a proportion of patients continue to face significant morbidity and mortality. Haemopoietic stem cell transplant (HSCT) has been recognized as an option for such patients. We analysed the evidence on efficacy and safety of HSCT in patients with SLE. A database search was done for articles on HSCT in SLE up to July 2017 in PUBMED, Cochrane library, LILACS and clinical trial registration databases to select prospective or retrospective studies with 8 or more patients. Of the 732 search results from the PUBMED, Cochrane and LILACS database search, following duplicate removal, 15 studies were eligible for detailed assessment. Findings of an additional trial were obtained from the clinical trial registration database. Data were extracted on study design, patient characteristics, nature of intervention, outcomes, complications and study quality. Case reports and small case series were summarised without detailed qualitative analysis. Most of the studies showed remission in the majority of patients. Relapse of the original disease increased with longer follow-up. Common adverse effects included: infections and secondary autoimmune disorders. Short follow up period and lack of randomised controlled trials were the main limitations restricting the generalizability of study results. A meta-analysis was not performed due to heterogeneity of studies. Although HSCT is a viable option in SLE, its exact clinical utility needs to be further evaluated in well-designed studies.

Abstract
Livedoid vasculopathy (LV) is a small vessel occlusive disease that can present with a painful purpuric eruption. Predominantly affecting young women, LV has been associated with hypercoagulable states and antiphospholipid syndrome. We present an unusual case of LV occurring in the setting of acute kidney injury secondary to lupus nephritis. It is important to differentiate LV from vasculitis as the treatment recommendation centers on anticoagulation therapy rather than immunosuppression. Additionally, antiphospholipid syndrome should be ruled out in cases of systemic lupus erythematosus with LV due to risk of thrombotic events.

Abstract
INTRODUCTION Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder with systemic manifestations and multiorgan involvement. Although primarily diagnosed, and managed in the outpatient setting, it can occasionally present with life-threatening complications that require rapid assessment and urgent aggressive therapy. Areas covered: In our review, we explore three organ systems that are often affected in SLE, but have the potential to present as medical emergencies; these are the kidney, the central nervous system, and the hematologic system. We take a case-based approach to each clinical scenario, with information given sequentially in order to reflect "real-life" situations where management decisions need to be made with limited information. We review the acute management, pathophysiology, diagnostic approach, and treatment along with a review of the literature, for lupus nephritis presenting as rapidly progressive glomerulonephritis, acute lupus transverse myelitis, and refractory antiphospholipid syndrome. Expert commentary: At the conclusion of each section, we provide an expert commentary regarding each issue, relating to diagnosis, early management, and current evidence behind treatment recommendations.

Abstract
BACKGROUND Neurodevelopmental disorders, as a class of diseases, have been particularly difficult to treat even when the underlying cause(s), such as genetic alterations, are understood. What treatments do exist are generally not curative and instead seek to improve quality of life for affected individuals. The advent of gene therapy via gene replacement offers the potential for transformative therapies to slow or even stop disease progression for current patients and perhaps minimize or prevent the appearance of symptoms in future patients. MAIN BODY This review focuses on adeno-associated virus (AAV) gene therapies for diseases of the central nervous system. An overview of advances in AAV vector design for therapy is provided, along with a description of current strategies to develop AAV vectors with tailored tropism. Next, progress towards treatment of neurodegenerative diseases is presented at both the pre-clinical and clinical stages, focusing on a few select diseases to highlight broad categories of therapeutic parameters. Special considerations for more challenging cases are then discussed in addition to the immunological aspects of gene therapy. CONCLUSION With the promising clinical trial results that have been observed for the latest AAV gene therapies and continued pre-clinical successes, the question is no longer whether a therapy can be developed for certain neurodevelopmental disorders, but rather, how quickly.

Abstract
Refractory antiphospholipid syndrome represents a challenge for preventing thrombosis that may occur despite adequate anticoagulation and immunomodulation therapy. Here, we report a 35-year-old male patient who presented with variable venous thromboembolic events. Autologous hematopoietic stem cell transplant was performed after conditioning with cyclophosphamide and antithymocyte globulin. Five years after transplant, the treatment continued to show a successful outcome in preventing new thrombotic events. Autologous hematopoietic stem cell transplant represents a chance for cure from antiphospholipid syndrome despite the paucity of reported data so far.

Abstract
BACKGROUND Hematopoietic stem cell transplantation (HSCT) has been proposed as a therapeutic option for patients with Systemic Lupus Erythematosus (SLE) refractory to standard therapy. This therapeutic approach has been applied to other severe autoimmune diseases refractory to standard therapy with promising results. AIM To systematically review the literature and analyze the available evidence on HSCT therapy in patients with SLE and antiphospholipid syndrome (APS), with a focus on therapy efficacy and occurrence of adverse events. METHODS A detailed literature search, applied to Ovid MEDLINE, In-Process and Other Non-Indexed Citation and Ovid Medline 1986 to 2014, has been developed a priori to identify articles that reported findings from clinical and laboratory studies that investigated the effect of HCT in patients with SLE. RESULTS Twenty-five studies met all inclusion criteria, including a total of 279 SLE patients; of those, 54 patients also fulfilled the classification criteria of APS. The majority of the studies reported an improvement after HSCT in terms of diseases activity control (assessed with SLEDAI, or time-free from diseases) or overall survival. However, one study reported no net benefit of HSCT when compared to immunosuppression alone. One retrospective study reported an overall survival at 5years of 81% in 28 SLE patients. Of note, 5 cases (9.3%) of aPL negativization were reported after HSCT in the APS patients. When combining these studies and analyzing these patients with APS, 32 out of 44 (73%) were able to discontinue anticoagulation after HSCT. Our findings also demonstrate a total of 86 infections in the pool of patients (30.8%), 3 of which resulted in the death of the patient (1.3%). We observed an annual incidence of infection of 11.9% with a mean follow up of 36.2months. CONCLUSION Preliminary results of HSCT as a therapeutic option for SLE appear promising. Further studies are warranted in order to assess the safety of the procedure for both the occurrence of secondary autoimmune disease and the rate of infection. However, the rate of adverse effects confines this option to very selected cases of SLE patients resistant or refractory to standard approaches.

Abstract
Neuropsychiatric systemic lupus erythematosus (NPSLE) is a generic definition referring to a series of neurological and psychiatric symptoms directly related to systemic lupus erythematosus (SLE). NPSLE includes heterogeneous and rare neuropsychiatric (NP) manifestations involving both the central and peripheral nervous system. Due to the lack of a gold standard, the attribution of NP symptoms to SLE represents a clinical challenge that obligates the strict exclusion of any other potential cause. In the acute setting, management of these patients does not differ from other non-SLE subjects presenting with the same NP manifestation. Afterwards, an individualized therapeutic strategy, depending on the presenting manifestation and severity of symptoms, must be started. Clinical trials in NPSLE are scarce and most of the data are extracted from case series and case reports. High-dose glucocorticoids and intravenous cyclophosphamide remain the cornerstone for patients with severe symptoms that are thought to reflect inflammation or an underlying autoimmune process. Rituximab, intravenous immunoglobulins, or plasmapheresis may be used if response is not achieved. When patients present with mild to moderate NP manifestations, or when maintenance therapy is warranted, azathioprine and mycophenolate may be considered. When symptoms are thought to reflect a thrombotic underlying process, anticoagulation and antiplatelet agents are the mainstay of therapy, especially if antiphospholipid antibodies or antiphospholipid syndrome are present. Recent trials on SLE using new biologicals, based on newly understood SLE mechanisms, have shown promising results. Based on what we currently know about its pathogenesis, it is tempting to speculate how these new therapies may affect the management of NPSLE patients. This article provides a comprehensive and critical review of the literature on the epidemiology, pathophysiology, diagnosis, and management of NPSLE. We describe the most common pharmacological treatments used in NPSLE, based on both a literature search and our expert opinion. The extent to which new drugs in the advanced development of SLE, or the blockade of new targets, may impact future treatment of NPSLE will also be discussed.

Abstract
UNLABELLED Essentials The clinical value of IgM antibodies in thrombotic antiphospholipid syndrome (APS) is debated. By review of literature, we reconsidered the clinical value of IgM antibodies in thrombotic APS. More significant correlations with thrombosis were found for the IgG compared to IgM isotype. Unavailability of paired IgG/IgM results hampers evaluating the added value of IgM positivity. Click to hear Dr de Groot's perspective on antiphospholipid syndrome SUMMARY Background Despite the update of the classification criteria for the antiphospholipid syndrome (APS), difficulties persist in the identification of patients at risk for thrombosis. Current guidelines include assays detecting IgG/IgM anti-β2 -glycoprotein I and anti-cardiolipin antibodies, although the relevance of IgM antibodies has been debated. Objectives Through a review of the literature from 2001 to 2014, we aimed to formally establish the thrombotic risk stratification potential of IgM as compared with IgG anti-phospholipid antibodies (aPLs). Patients/methods One thousand two hundred and twenty-eight articles were selected by a computer-assisted search of the literature. Of the 177 studies that met our inclusion criteria, the clinical value of IgG/IgM aPLs was established through analysis of odds ratios for thrombosis or percentage of positives in the thrombotic population. Results/conclusions We clearly found more significant correlations with thrombosis for the IgG than for the IgM isotype. Nonetheless, in a minority of studies, significant associations with thrombosis were found for IgM but not IgG antibodies. The unavailability of paired results of IgG and IgM for each separate patient hampers evaluation of the added value of isolated IgM positivity. To fully take advantage of results obtained by future studies, we strongly encourage scientists to provide all studied information per patient. We planned a large multicenter study to investigate clinical associations of isolated/combined positivity for criteria/non-criteria aPLs. Importantly, because of the presence of non-pathogenic aPLs, quantitative assays are characterized by a high false-positivity rate. Optimization of functional assays, such as thrombin generation measuring the whole scheme of coagulation, may help to reduce APS-related morbidity and mortality.

Abstract
Antiphospholipid syndrome (APS) is a prothrombotic disease characterized by thrombosis and pregnancy morbidity in the presence of antiphospholipid antibodies (apL). Management of thrombosis is based on long-term oral anticoagulation and patients with arterial events should be treated aggressively. Primary thrombo-prophylaxis is recommended in patients with systemic lupus erythromatosus (SLE) and obstetric APS. Obstetric APS care is based on high-risk management and treatment with aspirin and heparin. Possible future therapies include statins, hydroxychloroquine, rituximab, and new anticoagulant drugs. Current research is focused on targeting components of the complement system, interfering with aPL-mediated cell activation and using tailored peptides to block the pathogenic subpopulation of aPL.

Abstract
PURPOSE OF REVIEW To review novel therapeutic targets that are currently under investigation to develop safer, targeted therapies for antiphsopholipid antibody (aPL)-mediated clinical manifestations. RECENT FINDINGS Novel therapeutic options potentially available include anti-CD20 monoclonal antibodies and new-generation anticoagulants (such as direct thrombin and anti-Xa inhibitors). Research focusing on interfering with aPL-mediated cell activation, targeting complement components and the innovative concept of blocking the pathogenic subpopulation of aPL with tailored peptides are currently being explored. SUMMARY Antiphospholipid syndrome is an autoimmune disease characterized by thrombosis and pregnancy morbidity occurring in patients persistently positive for aPL. Current therapeutic options remain confined to long-term anticoagulation with vitamin K antagonists. The future holds much promise with the identification of novel potential targets, many of which are currently under investigation. The challenge will be to design prospective randomized controlled clinical trials to provide the evidence necessary to support integration of these therapies into clinical practice.

Selective adsorption of antiphospholipid and anti-dsDNA autoantibodies on histidine based pseudobioaffinity adsorbent from sera of patients with systemic lupus erythematosus (SLE). J Chromatogr B Analyt Technol Biomed Life Sci 2014; 975:77-83. [PMID: 25438246 DOI: 10.1016/j.jchromb.2014.11.005] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2014] [Revised: 10/29/2014] [Accepted: 11/08/2014] [Indexed: 11/22/2022]
Abstract
Systemic lupus erythematosus (SLE) is an autoimmune diseases characterized by the presence of antiphospholipid and anti-dsDNA autoantibodies in the sera of patients. These autoantibodies and their subclasses have received increasing attention by medical community due to their association with recurrent venous thrombosis, fetal loss and thrombocytopenia. In particular, attention has been paid to IgG subclasses in SLE. The biological and functional properties together with the subclass distribution might therefore influence the course of SLE. The separation and elimination of these autoantibodies from sera of patients can be effective in clinical therapy. In the present study, histidine based pseudobioaffinity adsorbents have been used for the selective adsorption and separation of anti-double stranded DNA (anti-dsDNA), anticardiolipin (aCL) and anti-β2-glycoprotein-I (anti-β2-GPI) antibodies from sera of patients with SLE. For this purpose histidine acting as a pseudobiospecific ligand has been coupled to bisoxirane activated sepharose CL-6B for the adsorption and separation of these autoantibodies. The removal of autoantibodies was carried out under gentle adsorption and elution chromatographic conditions at pH values 7.0 and 8.0. Autoantibodies isotypes and subclasses distribution in the separated fractions were studied by enzyme-linked immune-sorbent assay. The obtained results showed that the separated anticardiolipin and anti-β2-glycoprotein-I autoantibodies belong to IgG1, IgG2 and IgG3subclasses, while those of anti-dsDNA belong to IgM isotype and were shown to have a DNA hydrolyzing activity that hydrolyzes plasmid DNA. The results also indicate a total IgM and IgG recovery superior to 90% of the fraction loaded at pH 7.4 and pH 8.0 respectively.

Abstract
The antiphospholipid syndrome (APS) is defined by the association of high titers of antiphospholipid antibodies (aPLs) with thrombotic events and/or obstetrical problems. APS can be isolated or associated with immune system diseases. Several central nervous system (CNS) manifestations have been reported in APS, but are still not included in the international diagnostic criteria. We present here three cases of APS revealed by CNS manifestations. The first patient had a primary APS with stroke, dementia, epilepsy and the "so-called" Liebman-Sacks disease, a subacute thrombotic non-bacterial valvulopathy. The second one developed a primary APS with a Sneddon syndrome, while the third case is a neurolupus-associated APS with subacute encephalopathy, chorea, stroke, and epilepsy. The pathogenesis of the APS is related to both prothrombotic and immunologic effects of the aPLs. Long-term anticoagulation by low-weight heparin or warfarin is currently recommended in APS. We propose to search the presence of aPLs in any case of young adults' stroke, unexplained dementia, and acquired chorea.

Abstract
The antiphospholipid syndrome is characterized by a combination of laboratory findings (i.e., the presence of at least one antiphospholipid antibody) and clinical manifestations (arterial and/or venous thrombosis, obstetrical complications). Long-term oral anticoagulant is recommended to prevent recurrence of both arterial and venous thrombosis, whereas (low molecular weight) heparin plus aspirin is the treatment of choice to prevent further obstetrical complications. In the rare case of catastrophic antiphospholipid syndrome, heparin plus high-dose corticosteroids plus plasma exchange is associated with the highest recovery rate. Some new, non-antithrombotic-based treatments of antiphospholipid syndrome with rituximab, autologous stem cell transplantation, or hydroxychloroquine are also reviewed.

Abstract
UNLABELLED This article is a review of different management strategies for the hematological manifestations of systemic lupus erythematosus (SLE), the strategies include immunosuppressive drugs, some noval therapies and B-cell depletion for refractory thrombocytopenia in patients with SLE and in antiphospholipid antibody syndrome associated with SLE. The researcher questions the validity of the current classic treatment modes and the article explores the relationships between SLE hematological manifestations and the level of morbidity and mortality burden and focuses on the pathophysiology, diagnostic approaches and management strategies of these manifestations. The researcher focuses on hematological abnormalities because they are the commonest among most manifestations in SLE seen in Anemia, leucopenias and thrombocytopenia. They commonly result from an immune mediated bone marrow failure, excessive peripheral cells destruction or certain drugs and infections. There is also an association between anti-phospholipid antibody syndrome (APS) and SLE referred to as secondary APS or SLE-APS. Furthermore, it was recently found that mycophenolatemofetil acts as corticosteroids and as cyclophosphamide sparing agent. Although there is no specific therapy for cytopenias in SLE, corticosteroids remain the mainstay in the treatment of these patients along with less used other conventional treatment options such as azathioprine, cyclophosphamide and human normal immunoglobulin. There are other novel therapies such as thrombopoietin receptor agonists in thrombocytopenia and the use of autologous hematopoitic stem cells transplantation in refractory SLE-APS that are under review. Some of these therapies include thrombopoietin receptor agonists in thrombocytopenia and the use of autologous hematopoitic stem cells transplantation in refractory SLE-APS. The study concludes that treatment of hematological abnormalities is challenging because the treatment itself can cause undue complications sometimes such as granulocytosis due to infection or the use of high doses of steroids and may occur during acute exacerbations of SLE. It is important to take these factors into consideration for disease therapy and management.

Abstract
Stem cell transplant (SCT) has long been the standard of care for several hematologic, immunodeficient, and oncologic disorders. Recently, SCT has become an increasingly utilized therapy for refractory autoimmune rheumatologic disorders (ARDs). The efficacy of SCT in ARDs has been attributed to resetting an aberrant immune system either through direct immune replacement with hematopoietic stem cells or through immunomodulation with mesenchymal stem cells. Among ARDs, refractory systemic sclerosis (SSc) and systemic lupus erythematosus (SLE) are the most common indications for SCT. SCT has also been used in refractory rheumatoid arthritis, inflammatory myopathies, antiphospholipid syndrome, granulomatosis with polyangiitis, and pediatric ARDs. Complete responses have been reported in approximately 30 % of patients in all disease categories. Transplant-related mortality, however, remains a concern. Future large multi-center prospective randomized clinical trials will help to better define the specific role of SCT in the treatment of patients with ARDs.

Abstract
Two streams of research are at the origin of the utilization of hematopoietic stem cell transplantation (HSCT) for severe autoimmune diseases (SADs). The allogeneic approach came from experimental studies on lupus mice, besides clinical results in coincidental diseases. The autologous procedure was encouraged by researches on experimental neurological and rheumatic disorders. At present the number of allogeneic HSCT performed for human SADs can be estimated to not over 100 patients, and the results are not greatly encouraging, considering the significant transplant-related mortality (TRM) and the occasional development of a new autoimmune disorder and/or relapses notwithstanding full donor chimerism. Autologous HSCT for refractory SLE has become a major target. Severe cases have been salvaged, TRM is low and diminishing, and prolonged clinical remissions are obtainable. Two types of immune resetting have been established, "re-education" and regulatory T cell (Tregs) normalization. Allogeneic HSCT for SLE seems best indicated for patients with disease complicated by an oncohematologic malignancy. Autologous HSCT is a powerful salvage therapy for otherwise intractable SLE. The duration of remission in uncertain, but a favorable response to previously inactive treatments is a generally constant feature. The comparison with new biological agents, or the combination of both, are to be ascertained.

Abstract
The antiphospholipid syndrome (APS) is an autoimmune disorder presenting with tissue injury in various organs related to large- or small-vessel thrombosis associated with antiphospholipid and antiprotein/phospholipid complex antibodies. Although the pathophysiology, diagnosis, and clinical scenario may seem clear and straightforward, a more detailed examination reveals a more complex and uncertain picture related to the management of APS. This article reviews the current situation relating to APS therapy by evaluating the different clinical features of the syndrome ranging from thrombosis to pregnancy complications together with new strategies and pharmacological approaches.

Abstract
Autologous haematopoietic stem cell transplantation (AHSCT) has been proposed as a treatment modality which may arrest the autoimmune disease process and lead to sustained treatment-free remissions. Since the first consensus statement in 1997, approximately 200 autologous bone marrow or haematopoietic stem cell transplantations (HSCTs) have been reported worldwide for systemic lupus erythematosus (SLE). The current state of AHSCT in SLE was reviewed at a recent meeting of the autoimmune working party of the European Group for Blood and Marrow Transplantation. There was general agreement among experts in this field that in patients with severe SLE refractory to conventional immunosuppressive treatments, AHSCT can achieve sustained clinical remissions (ranging from 50% to 70% disease-free survival at 5 years) associated with qualitative immunological changes not seen with other forms of treatment. However, this clinical benefit is associated with an increase in short-term mortality in most studies. Improving patient selection, long-term follow-up of patients after AHSCT, optimisation of induction and maintenance treatment together with detailed analysis of the immune system are identified as key areas for future research. Optimally, AHSCT should be compared with conventional treatment in randomised controlled trials. Development of stronger transplant registries, defining a core set of clinical data and standardising biological sample collections would make future collaborations and comparison of studies more feasible.

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
Systemic lupus erythematosus (SLE) is considered the paradigm of autoimmune diseases (AD), and the murine models are known to be curable by means of allogeneic hematopoietic stem cell transplantation (HSCT). However autologous transplantations were predominantly utilized in the clinic, starting from 1996, and by now well over 150 very severe patients have been transplanted worldwide. Transplant-related mortality (TRM) in 153 cases was 7%, with a wide center effect (from 0-2% to 13%). The disease arresting effect was dramatic even in patients on dialysis, although ASCT should not be considered a last resource, salvage therapy, but a disease- modifying intervention to be utilized in the early stages of patently aggressive disease. The autoimmune biological parameters are consistently modified, although some degree of ANA-positivity generally persists. Similar encouraging results have been obtained in the primary antiphospholipid syndrome (APS) and in bullous disorders of the skin.

Abstract
BACKGROUND The characteristics and the clinical course of antiphospholipid syndrome (APS) in high-risk patients that are positive for all three recommended tests that detect the presence of antiphospholipid (aPL) antibodies have not been described. METHODS This retrospective analysis of prospectively collected data examined patients referred to Italian Thrombosis Centers that were diagnosed with definite APS and tested positive for aPL [lupus anticoagulant (LA), anti-cardiolipin (aCL), and anti-beta2-glycoprotein I (beta2GPI) antibodies]. Laboratory data were confirmed in a central reference laboratory. RESULTS One hundred and sixty patients were enrolled in this cohort study. The qualifying events at diagnosis were venous thromboembolism (76 cases; 47.5%), arterial thromboembolism (69 cases; 43.1%) and pregnancy morbidity (11 cases; 9.7%). The remaining four patients (2.5%) suffered from catastrophic APS. The cumulative incidence of thromboembolic events in the follow-up period was 12.2% (95% CI, 9.6-14.8) after 1 year, 26.1% (95% CI, 22.3-29.9) after 5 years and 44.2% (95% CI, 38.6-49.8) after 10 years. This was significantly higher in those patients not taking oral anticoagulants as compared with those on treatment (HR=2.4 95% CI 1.3-4.1; P<0.003). Major bleeding associated with oral anticoagulant therapy was low (0.8% patient/years). Ten patients died (seven were cardiovascular deaths). CONCLUSIONS Patients with APS and triple positivity for aPL are at high risk of developing future thromboembolic events. Recurrence remains frequent despite the use of oral anticoagulants, which significantly reduces the risk of thromboembolism.

Abstract
Immunoablation with autologous hematopoietic stem cell rescue has been used in over 1,300 autoimmune disease patients, around 150 with SLE. Some patients have experienced durable remissions with loss of autoantibodies, whereas others either did not respond or died as a result of the treatment. Prospective randomised trials are required and are being planned to establish the place for this potentailly curative strategy. Mesenchymal stem cells are in an exploratory phase for the treatment of acute autoimmune disease including SLE. The principle is that they home to inflammed tissue and exert an antiinflammatory paracrine effect.

Abstract
An association of antiphospholipid antibody syndrome with antibodies directed against either phospholipids or plasma proteins strongly suggest that B-cell dysfunction may be involved in its pathogenesis. Antiphospholipid antibody syndrome with autoimmune cytopenias shows a poor response rate to conventional treatment with anticoagulants, glucocorticosteroids, immunosuppressive agents, intravenous immunoglobulin or plasmapheresis. We report a case of life-threatening antiphospholipid antibody syndrome with Evans syndrome receiving successful multimodal treatment including anti-CD20 monoclonal antibody rituximab with long-term follow-up.

Abstract
Immunoablative therapy and hematopoietic stem cell transplantation (HSCT) is an intensive treatment modality aimed at 'resetting' the dysregulated immune system of a patient with immunoablative therapy and allow outgrowth of a nonautogressive immune system from reinfused hematopoietic stem cells, either from the patient (autologous HSCT) or a healthy donor (allogeneic HSCT). HSCT has been shown to induce profound alterations of the immune system affecting B and T cells, monocytes, and natural killer and dendritic cells, resulting in elimination of autoantibody-producing plasma cells and in induction of regulatory T cells. Most of the available data have been collected through retrospective cohort analyses of autologous HSCT, case series, and translational studies in patients with refractory autoimmune diseases. Long-term and marked improvements of disease activity have been observed, notably in systemic sclerosis, systemic lupus erythematosus, and juvenile idiopathic arthritis, and treatment-related morbidity and mortality have improved due to better patient selection and modifications of transplant regimens. Treatment-related mortality has decreased to approximately 7%. Prospective, randomised, controlled clinical trials are ongoing or planned in systemic sclerosis, systemic lupus erythematosus, and several nonrheumatological conditions.

Abstract
BACKGROUND Liver cirrhosis represents the end stage of chronic liver injury. Currently, liver transplantation provides the only definite cure but it is beset with many problems, including lack of donors and risk of rejection. Stem cell therapy is very attractive in this setting because it has the potential to help tissue regeneration. In this study, we aimed to investigate the therapeutic effect of peripheral blood monocyte cell (PBMC) transplantation in decompensated liver cirrhosis. METHODS A total of 40 subjects (31 men and nine females, age range 21-71 years) was recruited to two groups. Group 1 received granulocyte-colony-stimulating factor (G-CSF) mobilization, PBMC collection by leukapheresis and PBMC transplant therapy. Group 2 received G-CSF mobilization for 4 days. At baseline and 6 months after treatment, liver function of the two groups was monitored by blood examination and ultrasonagraphy. RESULTS Both groups gained significant improvement in liver synthetic function, such as serum albumin and prothrombin time, from baseline to 6 months after treatment (P<0.01). However, there was no significant difference in alanine aminotransferase, aspartate aminotransferase and total bilirubin in both groups (P>0.05). Compared with group 2, a significantly improved liver function was observed in group 1, including elevated serum albumin level and a decreased CTP score (P<0.05). No major adverse effects were noted. DISCUSSION Autologous PBMC transplantation could be considered as a novel and alternative treatment for patients with decompensated liver cirrhosis.

Abstract
Adult stem cells provide a promising alternative for the treatment of decompensated liver cirrhosis. Our previous study showed that peripheral blood monocytes (PBMCs) from decompensated liver cirrhosis could differentiate into hepatocyte-like cells in vitro. We here aimed to investigate the differential potential of the PBMCs under liver environment. PBMCs were isolated from one cirrhotic patient, who was mobilized by the recombinant human granulocyte colony stimulating factor for consecutive 3days, and then PBMCs were transplanted into nude mice by tail vein after labeled with PKH26-GL. The location of the transplanted PBMCs was identified by PKH26-GL staining and PRINS for human SRY gene. The expressions of human hepatocyte-markers were detected by immunohistochemistry, RT-PCR, and Western blot analysis. Our results demonstrated that PBMCs from decompensated liver cirrhosis could migrate into the liver of nude mice with human hepatocyte-markers expression, indicating that autologous PBMCs transplantation might be one alternative therapy for the decompensated liver cirrhosis.

Abstract
The arbitrary division between antiphospholipid antibody syndrome and secondary antiphospholipid antibody syndrome has not proven useful. Antiphospholipid antibodies in the absence of antiphospholipid antibody syndrome often occur as epiphenomena in many autoimmune diseases. They are very common in systemic lupus erythematosus. Antiphospholipid antibody syndrome is a significant comorbidity in lupus but is uncommon in Sjögren's syndrome, rheumatoid arthritis, scleroderma, and systemic vasculitis. Evidence is growing that antiphospholipid antibodies may have a pathogenic role in pulmonary hypertension and accelerated atherosclerosis of autoimmune diseases.

Abstract
PURPOSE During the past ten years, more than 1000 patients suffering from severe autoimmune disease have received an autologous haematopoietic stem cell transplant. These new therapeutic have been used in systemic sclerosis (scleroderma), multiple sclerosis, rheumatoid arthritis, juvenile idiopathic arthritis and systemic lupus erythematosus. CURRENT KNOWLEDGE AND KEY POINTS Autologous haematopoietic stem cell transplantation has become a curative option for condition with very poor prognosis as severe systemic sclerosis, lupus erythematosus or other systemic diseases. This review summarizes the current experience in the phase I and II clinical trials in Europe and North America. We describe the main results and the limits of stem cell transplantation in systemic diseases. FUTURE PROSPECTS AND PROJECTS Autologous haematopoietic stem cell transplant in the treatment of autoimmune disease has evolved from a experimental concept to a clinically feasible and powerful therapy for selected patients with severe disease.

Abstract
Abstract
Antiphospholipid antibodies including anticardiolipin antibodies, lupus anticoagulants, and anti–β2 glycoprotein-1–specific antibodies may identify patients at elevated risk of first or recurrent venous or arterial thromboembolism. Traditionally, published case series supplemented by anecdotal experience have formed the basis of management of patients with these autoantibodies. Over the past several years, studies have described the management of patients with key clinical manifestations of antiphospholipid antibodies, including patients with antiphospholipid antibody syndrome. As a result, evidence-based treatment recommendations are possible for selected patients with, or at risk of, thrombosis in the setting of antiphospholipid antibodies. Unfortunately, most patients encountered in clinical practice do not correspond directly with those enrolled in clinical trials. For such patients, treatment recommendations are based on experience, extrapolation, and less rigorous evidence. This article proposes 5 cases typical of those found in clinical practice and provides recommendations for therapy focused on a series of clinical questions. Whenever possible, the recommendations are based on evidence; however, in many cases, insufficient evidence exists, so the recommendation is experiential.

Abstract
Peripheral blood monocytes (PBMCs) have the potential to differentiate into various progenitor cells. Here we have investigated the differentiation potential of PBMCs derived from patients with HBV related decompensated liver cirrhosis into hepatocyte-like cells. In our clinical trial, the PBMCs from 2 patients were mobilized by the recombinant human granulocyte colony stimulating factor, followed by leukapheresis and transplantation of PBMCs. PBMCs, induced by recombinant human hepatocyte growth factors, were identified by the expression of hepatocyte markers and specific biological functions with biochemical assays in vitro. Patients showed a lasting clinical amelioration for more than one year after transplantation, and hepatocyte-like cells were identified by expressing liver specific genes, synthesizing albumin, urea, aspirate transaminase, and glycogen, which were all similar to the human normal hepatic cell line QZG. Our results clearly demonstrated that mobilized PBMCs from patients with HBV related decompensated liver cirrhosis could differentiate into functional hepatocyte-like cells, indicating the possibility of autologous cell transplantation for treating patients with HBV related decompensated liver cirrhosis.

Abstract
The concept of haemopoietic stem cell transplantation (HSCT) to treat severe autoimmune diseases has been around for several decades. Advances in the safety of HSCT have made it a clinical reality since 1995. Databases have registered around a thousand patients treated specifically for a wide range of diseases, predominantly multiple sclerosis (MS), systemic sclerosis (SSc), rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Phase I/II prospective and retrospective studies have supported the potential of autologous HSCT as a treatment option in severely affected patients, with profound and prolonged clinical responses in some diseases, although procedures are generally not curative. Allogeneic HSCT appears to offer curative potential, but the potential of high toxicity has limited its use in this context. The exact role of HSCT remains to be defined, particularly in the context of other advances in the treatment of autoimmune disease. Along with other groups, the European Group for Blood and Marrow Transplantation (EBMT) are overseeing several phase III trials in autologous transplantation. Given the risks of the HSCT, eligibility is restricted to patients who have severe, treatment resistant disease, in whom the prognosis is otherwise poor. This review aims to summarise the current published data in this evolving treatment for relatively rare patients with resistant or rapidly progressive disease where treatment options are otherwise limited. This cross-fertilization of knowledge between many specialties may provide increasing therapeutic opportunities in otherwise untreatable diseases. Moreover, destroying and rebuilding immune systems may provide insights into autoimmune diseases.

Abstract
Renal biopsies occasionally show a combination of thrombotic microangiopathy as a result of antiphospholipid syndrome and lupus nephritis. The thrombosis in this case preceded the onset of lupus probably by approximately 8 yr, consisting of repeated fetal loss and venous thrombosis. More severe disease may have both arterial and venous thrombotic manifestations, including pulmonary emboli and cerebrovascular lesions. The antiphospholipid syndrome bears no relationship to the class of lupus nephritis but is accompanied by more frequent and greater hypertension and greater azotemia and interstitial fibrosis, and is associated with worse outcomes than lupus nephritis without antiphospholipid syndrome.

Abstract
Patients with cardiac dysfunction may be at increased risk of cardiac toxicity when undergoing hematopoietic stem cell transplantation (HSCT), which may preclude them from receiving this therapy. Cardiac dysfunction is, however, common in systemic lupus erythematosus (SLE) patients. While autologous HSCT (auto-HSCT) has been performed increasingly for SLE, its impact on cardiac function has not previously been evaluated. We, therefore, performed a retrospective analysis of SLE patients who had undergone auto-HSCT in our center to determine the prevalence of significant cardiac involvement, and the impact of transplantation on this. The records of 55 patients were reviewed, of which 13 were found to have abnormal cardiac findings on pre-transplant two-dimensional echocardiography or multi-gated acquisition scan: impaired left ventricular ejection fraction (LVEF) (n = 6), pulmonary hypertension (n = 5), mitral valve dysfunction (n = 3) and large pericardial effusion (n = 1). At a median follow-up of 24 months (8-105 months), there were no transplant-related or cardiac deaths. With transplant-induced disease remission, all patients with impaired LVEF remained stable or improved; while three with symptomatic mitral valve disease similarly improved. Elevated pulmonary pressures paralleled activity of underlying lupus. These data suggest that auto-HSCT is feasible in selected patients with lupus-related cardiac dysfunction, and with control of disease activity, may improve.

Abstract
Systemic lupus erythematosus is an autoimmune connective-tissue disorder with a wide range of clinical features, which predominantly affects women, especially from certain ethnic groups. Diagnosis is based on clinical assessment supported by investigations, including the finding of autoantibodies. Treatments range from antimalarial agents to corticosteroids and immunosuppressive agents. This Seminar draws attention to advances in the epidemiology, genetics, cardiovascular risks, lupus nephritis, CNS disease, the antiphospholipid syndrome, assessment of disease activity and damage, and pregnancy related and quality of life issues. New therapeutic approaches, such as biological agents and mycophenolate mofetil, will also be discussed.

Abstract
A 49-year-old Caucasian man with antiphospholipid syndrome who experienced an ischemic stroke required multidisciplinary decisions regarding acute and long-term care. The patient first received warfarin and unfractionated heparin, followed by low-molecular-weight heparin. However, he developed complications from these drugs (warfarin-induced necrosis and heparin-induced thrombocytopenia), resulting in thigh necrosis and multiple additional cerebral and peripheral infarcts. His condition improved after warfarin and the heparins were discontinued, and a direct thrombin inhibitor, argatroban, was given intravenously for acute treatment. Argatroban is the only anticoagulant known to be safe in patients who experience an acute ischemic stroke in the setting of heparin-induced thrombocytopenia. For long-term anticoagulation, fondaparinux, an indirect, selective factor Xa inhibitor, was given subcutaneously. The patient received intravenous dexamethasone, later changed to azathioprine, for immunomodulatory treatment. He had significant improvement in his neurologic deficits without recurrent events over the next 18 months. Management of anticoagulation therapy in patients with antiphospholipid syndrome is complex and challenging, and therapeutic strategies need to be evaluated further.

Abstract
Plasma cells provide humoral immunity. They have traditionally been viewed mainly as short-lived end-stage products of B-cell differentiation that deserve little interest. This view is changing, however, because we now know that plasma cells can survive for long periods in the appropriate survival niches and that they are an independent cellular component of immunological memory. Studies of the biology of plasma cells reveal a mechanism of intriguing simplicity and elegance that focuses memory provided by plasma cells on recently encountered pathogens while minimizing the 'fading' of memory for pathogens encountered in the distant past. This mechanism is based on competition for survival niches between newly generated plasmablasts and older plasma cells.

Abstract
Antiphospholipid Syndrome (APS) is a form of immune mediated thrombophilia, presenting as recurrent thrombotic events and pregnancy morbidity, in association with positive laboratory tests for antiphospholipid antibodies (APA) in the form of Lupus Anticoagulant (LA) or anticardiolipin antibodies(ACA). Insights into the pathophysiology of the condition suggest that some antibodies are prothrombotic in vivo, and that the mechanism of thrombosis is likely to be multifactorial. APS has a broad spectrum of clinical presentations, and the laboratory diagnosis can be difficult due to heterogeneity of APAs and poor standardisation of laboratory tests. Anticoagulation is the mainstay of the management of the thrombotic and obstetric complications of APS. The risk of recurrent thrombosis appears to be high, and the duration and intensity of therapy remains controversial. Randomised controlled trials have shown that standard intensity anticoagulation is adequate in most cases of venous thrombosis. Further trials are required to establish whether high intensity coagulation is of benefit in recurrent or arterial thrombosis. The optimal management of recurrent fetal loss is debated and large studies are required to establish a clear benefit of heparin and aspirin over aspirin alone or supportive care.

Abstract
PURPOSE OF REVIEW To review the recently published studies that can guide physicians in the management of persistently antiphospholipid antibody (aPL)-positive patients. RECENT FINDINGS Two recent prospective randomized controlled trials of two intensities of warfarin concluded that both moderate and high-intensity anticoagulation are similarly protective in antiphospholipid syndrome patients after the first thrombosis. Despite lack of controlled studies, there is experimental evidence that hydroxychloroquine and statins may play a role in the management of aPL-positive patients. In the mouse model of antiphospholipid syndrome that involves the injection of high-titer antiphospholipid syndrome human serum, complement activation is essential in aPL-mediated fetal loss and heparin prevents aPL-induced complement activation. SUMMARY Primary thrombosis prevention in persistently aPL-positive individuals lacks an evidence-based approach; elimination of reversible thrombosis risk factors and prophylaxis during high-risk periods is crucial. Secondary thrombosis prevention in persistently aPL-positive individuals lacks a risk-stratified approach; although the current recommendation is life-long warfarin, the necessity, duration, and the intensity of warfarin are still debated. Catastrophic antiphospholipid syndrome patients usually receive a combination of anticoagulation, corticosteroids, intravenous immunoglobulin, and plasma exchange; there is a clear need to test new agents. A common strategy to prevent fetal loss in aPL-positive patients with history of pregnancy morbidities is low-dose aspirin and heparin; if patients fail this regimen, the next step is the addition of intravenous immunoglobulin although this is not supported by controlled studies. Currently, there is no evidence that anticoagulation is effective for nonthrombotic manifestations of antiphospholipid antibodies.
