Abstract
BACKGROUND AND OBJECTIVES Resistant lupus nephritis (LN) has been associated with the persistence of long-lived plasma cells. Preliminary studies identified bortezomib as a potential treatment option for patients with refractory LN. The aim of this study was to analyze the efficacy and safety of bortezomib in the treatment of severe refractory LN. METHODS This retrospective study included 12 female patients diagnosed for the first time with class IV or IV/V LN with acute or rapidly progressive kidney injury (n = 11) and/or severe nephrotic syndrome (n = 1) who showed resistance to induction therapy with cyclophosphamide, steroids, mycophenolate, and rituximab, and were treated with either intravenous or subcutaneous bortezomib plus intravenous dexamethasone. RESULTS All patients with acute or rapidly progressive kidney injury showed a significant reduction in both biochemical and immunological activity after a mean of 6 (minimum 5, maximum 7) weekly cycles of bortezomib regimen, with a significant increase in C3 levels and a significant decrease of anti-ds DNA antibody titers, Systemic Lupus Erythematosus Disease Activity Index score, serum creatinine, and proteinuria. One patient (8.3%) achieved a complete response, and 10 patients (83.4%) achieved a partial response. During follow-up, all these patients maintained partial responses under treatment with mycophenolate and low-dose glucocorticoids. The patient with refractory nephrotic syndrome showed a partial response but relapsed 11 months after the end of bortezomib treatment and was resistant to treatment. A significant decrease in serum IgG levels after initiation of bortezomib treatment was observed in all patients, five of them (41.6%) showed hypogammaglobulinemia (<500 mg/dl), but no patient suffered from opportunistic infections; in only two patients (16.6%) hypogammaglobulinemia persisted at the end of follow-up. Two patients (16.6%) suffered from sensory neuropathy, which led to bortezomib treatment discontinuation. CONCLUSIONS Bortezomib may be an effective option for refractory LN, but close monitoring must be performed for possible adverse events such as peripheral neuropathy and hypogammaglobulinemia.

ANA Negative Systemic Lupus Erythematosus Leading to CTEPH, TTP-Like Thrombocytopenia, and Skin Ulcers. Case Rep Rheumatol 2016; 2016:4507247.

Abstract
SLE affects almost every organ system, with differing degrees of severity. During its clinical course periods of flares may alternate with periods of remission culminating in disease and therapy related damage. We describe a case of ANA negative SLE with severe thrombocytopenia, cutaneous vasculitis, antiphospholipid antibody syndrome, and pulmonary artery hypertension. As there is no definitive cure for SLE the treatment lies in caring for the individual organ systems involved and simultaneously taking care of the patient as a whole.

Abstract
Autoimmune diseases, such as rheumatoid arthritis, multiple sclerosis, autoimmune hepatitis and inflammatory bowel disease, have complex pathogeneses and the factors which cause these disorders are not well understood. But all have in common that they arise from a dysfunction of the immune system, interpreting self components as foreign antigens. Systemic lupus erythematosus (SLE) is one of these complex inflammatory disorders that mainly affects women and can lead to inflammation and severe damage of virtually any tissue and organ. Recently, the application of advanced techniques of genome-wide scanning revealed more genetic information about SLE than previously possible. These case-control or family-based studies have provided evidence that SLE susceptibility is based (with a few exceptions) on an individual accumulation of various risk alleles triggered by environmental factors and also help to explain the discrepancies in SLE susceptibility between different populations or ethnicities. Moreover, during the past years new therapies (autologous stem cell transplantation, B cell depletion) and improved conventional treatment options (corticosteroids, traditional and new immune-suppressants like mycophenolate mofetile) changed the perspective in SLE therapeutic approaches. Thus, this article reviews genetic aspects of this autoimmune disease, summarizes clinical aspects of SLE and provides a general overview of conventional and new therapeutic approaches in SLE.

Abstract
Intravenous immunoglobulins (IVIGs) are beneficial and safe for various diseases other than primary immunodeficiencies. Over the years, IVIG has been given for autoimmune diseases as an off-label adjunct therapy. While other biologic agents are indicated for rheumatoid arthritis (RA), IVIG may have a role for specific subgroups of RA patients where anti-cytokine blockers or rituximab may be unwarranted. Such subgroups may include patients with vasculitis, overlap rhupus syndrome, severe infections with active disease, and pregnancy. In addition, IVIG may be considered for juvenile chronic arthritis (JCA) and adult Still's disease. We review the literature for IVIG treatment in RA patients and for these subgroups.

Abstract
The occurrence of nephritis in patients with systemic lupus erythematosus is associated with increased morbidity and mortality. The pathogenesis of lupus nephritis is complex, involving innate and adaptive cellular and humoral immune responses. Autoantibodies in particular have been shown to be critical in the initiation and progression of renal injury, via interactions with both Fc-receptors and complement. One approach in the management of patients with lupus nephritis has been the use of intravenous immunoglobulin. This therapy has shown benefit in the setting of many forms of autoantibody-mediated injury; however, the mechanisms of efficacy are not fully understood. In this paper, the data supporting the use of immunoglobulin therapy in lupus nephritis will be evaluated. In addition, the potential mechanisms of action will be discussed with respect to the known involvement of complement and Fc-receptors in the kidney parenchyma. Results are provocative and warrant additional clinical trials.

Abstract
Systemic lupus erythematosus (SLE) is a disease of unknown cause that may involve one or many organ or systems. Skin involvement is a major feature in this disease, and a wide variety of skin conditions may be present. Lupus erythematosus panniculitis (LEP) constitutes a rare form of cutaneous lupus characterized by recurrent nodular or plaque lesions that can vary from a benign and mild course to a more disfiguring disease. Initial therapy includes corticosteroids, antimalarials, and azathioprine and, in refractory cases, two antimalarials in association, mycophenolate mofetil, or other immunomodulators. Intravenous immuglobulin (IVIG) is used in many autoimmune disorders, like in SLE, although clinical trials have not yet taken place. In this report, we review skin manifestations of SLE and their treatment, IVIG, and finally a case of LEP successfully treated with IVIG when other therapy modalities failed.

Abstract
Pregnancy in a woman with systemic lupus erythematosus (SLE) can be complicated by both lupus activity and pregnancy mishaps. The majority of recent studies found an increase in lupus activity during pregnancy, perhaps exacerbated by hormonal shifts required to maintain pregnancy. Increased lupus activity, in turn, prompts an elevated risk for poor pregnancy outcomes, including stillbirth, preterm birth, low birth weight, and preeclamspsia. Fortunately, the majority of pregnancies in women with SLE are successful. However, the interaction between pregnancy and SLE activity can lead to complications for both mother and baby.

Abstract
This review documents the remarkable progress systemic lupus erythematosus (SLE) has made in the past 40 years especially in Asia. It provides a kaleidoscope in terms of prevalence, ethnic and regional variations, disease manifestation, treatment strategies, and outcome. From a seminal paper on the use of intravenous cyclophosphamide in 1964 from Singapore to the use of mycophenolate mofetil in 2000 from Hong Kong and Guangzhou, the prognosis of lupus has changed dramatically in the last few decades. With more targeted therapies and better translational research, this progress is set to continue in the coming years. From an acute fulminating illness, lupus has now evolved to one with a chronic, relapsing course. The main causes of morbidity and mortality are now either treatment-related or patient-related rather than the disease itself. The present time is one of unprecedented growth of new therapeutic approaches and reevaluation of past treatment modalities. With improving socioeconomic conditions in the region, we anticipate further rapid progress in disease outcome. Although living with the wolf is still an ordeal for our patients, optimism has now replaced nihilism in the lupus world. There is light at the end of the tunnel.

Abstract
BACKGROUND AND OBJECTIVES Intravenous immunoglobulin (IVIG) is used for an increasingly diverse number of therapeutic applications as an immunomodulation drug. Although it has demonstrated therapeutic effectiveness, the mechanism of action of IVIG in these disorders is poorly understood; this lack of understanding complicates rational clinical application and reimbursement for 'off-label' use. MATERIALS AND METHODS Selected literature on the clinical use of IVIG as an immunomodulation drug is reviewed. We present a brief description of DNA microarray and protein microarray technology and the application of such technologies to the study of immune system cells. The several studies on the application of DNA microarray technology to study gene expression in response to IVIG are presented. RESULTS There is increasing data on the use of DNA microarray and protein microarray technology to study gene expression in immune system cells including T cells, B cells, macrophages, and leucocytes. There is less information on the effect of IVIG on gene expression in immune system cells. However, there is sufficient information available to suggest that this is a practical approach with the caveat that such work will require careful experimental design and clear definition of the normal population. CONCLUSIONS DNA and protein microarray assays can be used to (i) provide rational indications for the clinical use of IVIG, (ii) provide for specific analysis of raw material and end product IVIG in screening for content related to immunomodulation, and (iii) accelerate the development of next generation products which would be more focused and/or targeted therapeutics.

Abstract
Systemic lupus erythematosus is an autoimmune multi-system disease of uncertain aetiology with highly variable clinical manifestations. Women of child-bearing age are most often affected; however, approximately 10-20% of cases occur in older patients. Elderly-onset lupus has been defined in various studies as onset of lupus after age 50-65 years. Menopause and changes in cellular immunity with aging may contribute to development of lupus in older adults. Many studies suggest that the clinical and serological features of elderly-onset lupus differ from those of lupus in younger patients. Arthritis, fever, serositis, sicca symptoms, Raynaud's syndrome, lung disease and neuropsychiatric symptoms are more common in patients with elderly-onset lupus, while malar rash, discoid lupus and glomerulonephritis are less common in elderly-onset patients compared with younger lupus patients. Most elderly-onset lupus patients have a positive anti-nuclear antibody test, but the prevalence of anti-double-stranded DNA and hypocomplementaemia is lower in elderly-onset patients than in younger patients. Rheumatoid factor, anti-Ro/Sjögren's syndrome (SS) A and anti-La/SSB are more often positive in elderly-onset patients. The diagnosis of elderly-onset lupus may be delayed for many months: insidious onset, low prevalence and similarity to other more common disorders make the diagnosis of lupus challenging in this population. Treatment of lupus in the elderly may be complicated by co-morbidities and increased risk of toxicities from usual treatments. Optimal management of elderly-onset lupus is empiric because of a lack of randomised controlled studies. However, the approach to treatment is similar regardless of the age of the patient. This article discusses the prevalence, clinical course, serological features, prognosis and treatment of elderly-onset systemic lupus erythematosus.

Abstract
There has been unprecedented growth in new therapeutic approaches for the treatment of systemic lupus erythematosus (SLE). These approaches include re-evaluation of the doses and duration of therapy with traditional agents, including intravenous cyclophosphamide and azathioprine. Drugs that were developed for other uses are being applied to specific SLE manifestations, and have spurred larger scale trials for overall disease activity. In addition, several new agents show promise in clinical trials; many have safer toxicity profiles than do traditional therapies. Some of these agents have multiple immunomodulatory effects, whereas others interfere with a specific immunologic process in one of the pathogenetic pathways of SLE activity.

Abstract
Intravenous immunglobulin (IVIg) is used to treat a number of immune-deficiences and autoimmune diseases. Safety concerns related to a number of reported thromboembolic complications prompted us to review the literature. These complications happened mainly in individuals that had risk factors for thromboembolism, like advanced age, previous thromboembolic diseases, bed-ridden, and in individuals in which high doses or high infusion rates of IVIg were administered. The mechanism responsible for these events seems to be a rise in plasma viscosity that can trigger a thromboembolic event, especially in cases in which there is an underlying circulation impairment. Complications can be minimized by using IVIg only in clear-cut indications, weighting risk versus benefit in patients who are at high risk for thromboembolism and by sticking to carefully monitored slow infusion rates. IVIg for the treatment of autoimmune disorders should be administered as a five-day course of 2 g/kg of body weight. Each daily dose of 400 mg/kg should be given in not less than eight hours.

Abstract
Intravenous immunoglobulin (IVIG) is a safe preparation, made of human plasma of thousands of healthy donors. The fascinating history of gamma globulin therapy begins in 1930 when Finland treated pneumococcal pneumonia patients with equine serum, which prolonged their survival from pneumonia. Since then, significant breakthroughs were achieved by Cohn, Bruton, Imbach, and others, whose clinical contribution to the world of medicine was of great importance. Originally IVIG was used to treat immunodeficiencies. Later on the use of IVIG extended to autoimmune diseases as well. The efficacy of IVIG has been established only in several autoimmune diseases; clinical reports of trials, series, and case reports indicate significant improvement in many more autoimmune diseases. IVIG have also showed antimetastatic effects in a variety of cancer cell lines, as well as in a few case reports. The efficiency of IVIG has also been observed in recurrent pregnancy loss (RPL), either as a result of an autoimmune disease or spontaneous. Several attempts were made to discover the immunomodulatory effects of IVIG, but it is still not fully understood. Clearly IVIG has multiple mechanisms of actions, which are thought to cooperate synergistically. One of the main mechanisms of actions of IVIG is its ability to neutralize pathogenic autoantibodies via anti-idiotypic antibodies within IVIG preparation. The ability of IVIG to neutralize pathogenic autoantibodies is of great importance in many autoimmune diseases, as well as in RPL. In cancer cell lines, IVIG modulates the immune system in a few ways, including the induction of IL-12 secretion, which consequently activates natural killer cells, and the induction of expression of proapoptotic genes only in cancer cells. Side effects from IVIG are rare and mostly mild and transient. More importantly adverse effects can be minimized by administration to a selective patient population in a proper way: slow infusion rate of 0.4 g/Kg body weight IVIG for 5 consecutive days, given in monthly cycles. The only downside of IVIG therapy is its high price. Therefore, clinicians should balance efficiency versus cost in deciding whether or not to treat certain conditions with IVIG.

Abstract
An ongoing production of IFN-alpha may be of etiopathogenic significance in systemic lupus erythematosus (SLE). It may be due to the natural IFN-producing cells (NIPC), also termed plasmacytoid dendritic cells (PDC), activated by immune complexes that contain nucleic acids derived from apoptotic cells. We here examined the role of FcgammaR in the IFN-alpha production in vitro by PBMC induced by the combination of apoptotic U937 cells and autoantibody-containing IgG from SLE patients (SLE-IgG). The Fc portion of the SLE-IgG was essential to induce IFN-alpha production, because Fab fragments or F(ab')(2) were ineffective. Normal, especially heat-aggregated, IgG inhibited the IFN-alpha production, suggesting a role for FcgammaR on PBMC. Using blocking anti-FcgammaR Abs, the FcgammaRIIa,c (CD32) but not FcgammaRI or FcgammaRIII were shown to be involved in the IFN-alpha induction by apoptotic cells combined with SLE-IgG, but not by HSV or CpG DNA. In contrast, the action of all of these inducers was inhibited by the anti-FcgammaRIIa,b,c mAb AT10 or heat-aggregated IgG. Flow cytometric analysis revealed that approximately 50% of the BDCA-2-positive PBMC, i.e., NIPC/PDC, expressed low but significant levels of FcgammaRII, as did most of the actual IFN-alpha producers activated by HSV. RT-PCR applied to NIPC/PDC purified by FACS demonstrated expression of FcgammaRIIa, but not of FcgammaRIIb or FcgammaRIIc. We conclude that FcgammaRIIa on NIPC/PDC is involved in the activation of IFN-alpha production by interferogenic immune complexes, but may also mediate inhibitory signals. The FcgammaRIIa could therefore have a key function in NIPC/PDC and be a potential therapeutic target in SLE.

Abstract
This article first reviews the current treatment of lupus nephritis, with a focus on the most serious forms, that is, the proliferative subtypes. Current standards for treatment have been developed empirically. Corticosteroids form the basis of all regimens. Cyclophosphamide given intravenously for prolonged periods is the current gold standard. Azathioprine can be regarded as an effective drug for maintenance treatment of lupus nephritis. Studies on its efficacy in schedules for remission induction are in progress. It has been learned from studies on 'conventional' immunosuppression that randomised, clinical trials should comprise large numbers of patients and a follow-up of many years to elucidate differences between effective strategies. These requirements are not met by any of the 'new' treatments we discuss in this review. There is only limited experience in patients with lupus nephritis with drugs that are currently used for immunosuppression in other autoimmune diseases, such as methotrexate, cyclosporin and high-dose intravenous gammaglobulins, nor with new immunosuppressive drugs that have been developed for immunosuppression in organ transplantation (mycophenolate mofetil, tacrolimus, fludarabine and cladribine). Hormonal therapy with the weak androgen prasterone (dehydroepiandrosterone; DHEA) has no role in treatment of active lupus nephritis. There are interesting experiences with agents that have evolved from progress in immunobiology and in our understanding of immunological processes. These modalities enable more specific immunosuppression and include monoclonal antibodies directed at immune cells, cytokines and components of the complement system, constructs developed to induce tolerance in pathogenic B cells, and gene therapy. Finally, we review data on autologous bone marrow transplantation in patients with systemic lupus erythematosus. We conclude that some strategies (like mycophenolate mofetil) are good candidates for further investigation in large-scale, prospective, randomised trials with prolonged follow-up (which are almost by definition hard to perform). Most new biological agents still are in a pre-clinical phase.

Abstract
Normal immunoglobulin G for therapeutic use (intravenous immunoglobulin [IVIg]) is used in an increasing number of immune-mediated conditions, including acute and chronic/relapsing autoimmune diseases, transplantation, and systemic inflammatory disorders. Several mutually nonexclusive mechanisms of action account for the immunoregulatory effects of IVIg. Although IVIg inhibits T-cell proliferation and T-cell cytokine production, it is unclear whether these effects are directly dependent on the effects of IVIg on T cells or they are dependent through the inhibition of antigen-presenting cell activity. Here, we examined the effects of IVIg on differentiation, maturation, and function of dendritic cells (DCs). We show that IVIg inhibits the differentiation and maturation of DCs in vitro and abrogates the capacity of mature DC to secrete interleukin-12 (IL-12) on activation while enhancing IL-10 production. IVIg-induced down-regulation of costimulatory molecules associated with modulation of cytokine secretion resulted in the inhibition of autoreactive and alloreactive T-cell activation and proliferation. Modulation of DC maturation and function by IVIg is of potential relevance to its immunomodulatory effects in controlling specific immune responses in autoimmune diseases, transplantation, and other immune-mediated conditions.

Abstract
Systemic lupus erythematosus (SLE) is an inflammatory chronic disease characterized by the presence of activated helper T-cells that induce a B-cell response, resulting in the secretion of pathogenic autoantibodies and the formation of immune complexes. SLE in children is a disease of low prevalence with a wide range of clinical manifestations, which means that the number of randomized controlled studies are few and usually involve a small number of patients. In recent years, new therapeutic agents have appeared and the role of older treatments has been clarified. Many of these treatments are designed to reduce inflammation. The spectrum is broad and ranges from traditional nonsteroidal anti-inflammatory drugs (NSAIDs) to cytotoxic agents that have anti-inflammatory effects. The current treatment of children or adults depends on the clinical expression of the disease. Minor manifestations usually respond to the administration of NSAIDs, low doses of corticosteroids, hydroxychloroquine, or methotrexate. Thalidomide could be used for refractory skin lesions. Major manifestations can endanger the patient's life and require early, aggressive treatment. Kidney disease and other manifestations have been related to the formation or deposit of tissular immune complexes. Therefore, for years the main aim of treatment has been to suppress the immune response. The immunosuppressant treatments used in children with SLE include high doses of corticosteroids, azathioprine, methotrexate, cyclosporine, and cyclophosphamide. Several combinations of medications have been used to obtain a rapid remission or to reduce the risk of toxicity of prolonged administration of cytotoxic agents. Intravenous gamma-globulin has been successfully used in the treatment of lupus nephritis, vasculitis, and acute thrombocytopenia. In spite of numerous published studies, the use of these drugs is still controversial. The immunosuppression achieved with these treatments is nonspecific, not always effective, and associated with significant toxicities; the most significant being growth retardation, accelerated atherosclerosis and severe infectious complications. The purpose of new biological therapies is to achieve specific immunosuppression, which makes it possible to design more effective and less toxic therapeutic strategies. Mycophenolate mofetil is a promising alternative in patients who do not respond to high doses of cyclophosphamide or azathioprine. Some recently developed monoclonal antibodies such as anti-CD40L or anti-IL-10, or other molecules such as LJP394 may prove useful in the near future. Finally, stem cell transplantation may be proposed in patients with severe juvenile-onset SLE who do not respond to any treatment.

Abstract
This article reviews and cites only publications relating to the management of lupus that have appeared since 1999. The data in these publications demonstrate that preventive and proactive strategies are as important as medication in improving the quality of life and life span of the patient with lupus. The use of lasers and thalidomide represents major advances in cutaneous lupus. The first major study over 25 years using nonsteroidal anti-inflammatory drugs to manage lupus suggests benefits. Further evidence was presented showing that dehydroepiandrosterone, leflunomide, and methotrexate are effective in treating mild to moderate disease. Various iterations and modifications of traditional cyclophosphamide therapy with or without mycophenolate mofetil, cyclosporine, and azathioprine continue to be studied for treating organ-threatening disease. Intravenous gamma globulin and selective apheresis are niche therapies appropriate in a few, highly selected patients. Immunoablative doses of cyclophosphamide appear to be as effective as stem cell transplantation for serious disease resistant to conventional doses of cyclophosphamide. Twelve biologic agents have been studied in lupus since 1999, with only LJP-394 showing clear-cut, convincing efficacy.

Abstract
The clinical and renal biopsy predictors of assistance in determining therapy are reviewed. While pulse cyclophosphamide remains the most effective treatment for proliferative nephritis, there is increasing interest in other agents, such as azathioprine, particularly to maintain remission. While lupus membranous nephropathy has attracted limited study, preliminary work suggests a role for cyclophosphamide. Newer therapies, including cyclosporine A, mycophenolate mofetil, immunoadsorption, intravenous immune globulin, LJP-394, high-dose immunoablation and nucleoside analogues require further study but offer hope for those failing conventional treatments.
