Abstract
PURPOSE To assess the efficacy and short-term safety of appropriately monitored pulse IV cyclophosphamide therapy in the treatment of patients with severe or treatment-resistant autoimmune ocular inflammatory disease. DESIGN Retrospective noncomparative interventional case series. PARTICIPANTS Thirty-eight patients with severe or recalcitrant ocular inflammation of diverse etiologies. METHODS Charts of patients seen on the Ocular Immunology & Uveitis Service at the Massachusetts Eye & Ear Infirmary were reviewed. Thirty-eight consecutive patients treated with pulse IV cyclophosphamide between January 1995 and March 2002 were analyzed. MAIN OUTCOME MEASURES The control of inflammation, steroid-sparing effect, visual acuity, and adverse reactions. RESULTS A positive response to treatment occurred in 68% of patients during the study period, with 55% achieving complete quiescence. A steroid-sparing effect was achieved in all patients previously on systemic steroid, allowing successful discontinuation of the drug in 41%. Visual acuity was maintained in 66% and improved in 21% of involved eyes. The most common side effects observed were fatigue (63%), nausea (32%), and headache (22%). None required a permanent discontinuation of therapy. CONCLUSIONS Pulse IV cyclophosphamide is an effective therapeutic modality in patients with severe or treatment-resistant ocular inflammatory disease.

Abstract
BACKGROUND Although much is known about the natural history of systemic lupus erythematosus (SLE), the development of SLE autoantibodies before the diagnosis of the disease has not been extensively explored. We investigated the onset and progression of autoantibody development before the clinical diagnosis. METHODS The Department of Defense Serum Repository contains approximately 30 million specimens prospectively collected from more than 5 million U.S. Armed Forces personnel. We evaluated serum samples obtained from 130 persons before they received a diagnosis of SLE, along with samples from matched controls. RESULTS In 115 of the 130 patients with SLE (88 percent), at least one SLE autoantibody tested was present before the diagnosis (up to 9.4 years earlier; mean, 3.3 years). Antinuclear antibodies were present in 78 percent (at a dilution of 1:120 or more), anti-double-stranded DNA antibodies in 55 percent, anti-Ro antibodies in 47 percent, anti-La antibodies in 34 percent, anti-Sm antibodies in 32 percent, anti-nuclear ribonucleoprotein antibodies in 26 percent, and antiphospholipid antibodies in 18 percent. Antinuclear, antiphospholipid antibodies, anti-Ro, and anti-La antibodies were present earlier than anti-Sm and anti-nuclear ribonucleoprotein antibodies (a mean of 3.4 years before the diagnosis vs. 1.2 years, P=0.005). Anti-double-stranded DNA antibodies, with a mean onset 2.2 years before the diagnosis, were found later than antinuclear antibodies (P=0.06) and earlier than anti-nuclear ribonucleoprotein antibodies (P=0.005). For many patients, the earliest available serum sample was positive; therefore, these measures of the average time from the first positive antibody test to the diagnosis are underestimates of the time from the development of antibodies to the diagnosis. Of the 130 initial matched controls, 3.8 percent were positive for one or more autoantibodies. CONCLUSIONS Autoantibodies are typically present many years before the diagnosis of SLE. Furthermore, the appearance of autoantibodies in patients with SLE tends to follow a predictable course, with a progressive accumulation of specific autoantibodies before the onset of SLE, while patients are still asymptomatic.

Abstract
BACKGROUND AND OBJECTIVE Cardiovascular disease is a major cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE). An association between hyperhomocysteinemia and increased cardiovascular risk has been reported. On the other hand, renal failure and deficiency of vitamin B12 and/or folic acid are common causes of hyperhomocysteinemia. The aims of this study were to determine plasma total homocystein (tHcy) concentrations in SLE patients and to analyze the association of plasma tHcy with age, sex, plasma creatinine, vitamin B12, folates and total cholesterol, as well as with other clinical conditions linked to atherothrombosis in SLE patients. PATIENTS AND METHOD Fasting plasma levels of tHcy, vitamin B12, folates, total cholesterol and creatinine were measured in 94 SLE patients (11 males, 83 females) and in a control group of 308 healthy volunteers (122 males, 186 females). A review of the medical records of SLE patients was performed. RESULTS Plasma tHcy concentrations were higher in patients with SLE (median 10.54 (mol/L) than in controls (median 8.49 (mol/L, p < 0.001). Hyperhomocysteinemia (tHcy >=15 (mol/L) was found in 17.02% SLE patients. In a multivariate analysis, plasma creatinine (p < 0.001), total cholesterol (p = 0.038), male sex (p = 0.003) and smoking (p = 0.001) were associated with higher plasma tHcy concentrations. No associations were found between plasma tHcy and hypertension, SLE duration, prednisone therapy and antiphospholipid antibodies. CONCLUSIONS Plasma tHcy concentrations are higher in SLE patients than in healthy controls. High concentrations of plasma creatinine and total plasma cholesterol, male sex and smoking are associated with a higher concentration of plasma tHcy in SLE. Since the clinical consequences of hyperhomocysteinemia are not well established, routine determination of plasmatic tHcy and supplemental therapy in patients with high levels of tHcy are not recommended.

Abstract
OBJECTIVE To evaluate the differences in the outcome of lupus nephritis diagnosed either in the 1980s or the 1990s in Heidelberg, Germany. METHODS Fifteen patients with biopsy confirmed lupus nephritis (LN) were followed up between 1980 and 1989 and 41 patients were followed up between 1990 and 2000. Their status at diagnosis and their treatment schedules and outcome were analysed. 68% had WHO IV nephritis. RESULTS In the decade from 1990 to 2000 there was significantly less proteinuria (46 v 17 g/l, p=0.008), significantly lower rates of renal failure (40% v 17%, p=0.02), and fewer histological signs of chronicity (33% v 10%, p=0.01) at the time of diagnosis of LN than in the decade from 1980 to 1989. The mean (SD) time from the first appearance of proteinuria until kidney biopsy was significantly shorter in the later decade (15.4 (15.6) v 3.9 (4.7) months). Although treatment schedules were not significantly different, the outcome of the disease was significantly better in the patients who were diagnosed with LN between 1990 and 2000 (p=0.045). Whereas 6/15 (40%) patients between 1980 and 1989 had terminal renal failure after a mean time of 94 months, in the group of 1990-2000 no patient developed terminal renal failure (median observation time 24 months). In both groups one patient died from infection. A high chronicity index in histology and the presence of arterial hypertension or renal failure, or both, at the time of diagnosis were significant risk factors for the development of terminal renal failure in the course of the disease. CONCLUSIONS The outcome of patients with newly diagnosed LN was significantly better between 1990 and 2000 than between 1980 and 1989. Kidney damage and chronic histological changes at time of diagnosis were significantly less common between 1990 and 2000, which is attributable to earlier diagnosis and treatment in the later decade.

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
Therapeutic antibodies directed against tumor necrosis factor alpha (TNF-alpha) for the treatment of rheumatoid arthritis, and against the human EGF receptor-2 (HER2) receptor for the treatment of breast cancer have provided significant clinical benefit for the patients. The success of these antibodies has also provided strong support for the possibility that increased activity of cytokines or growth factors is causally implicated in a variety of human diseases. Interferon alpha (IFN-alpha) is induced by viruses (linked by epidemiological studies to autoimmune diseases), has significant direct effects on both epithelial cells and the immune system, and then can be further induced by the autoantibodies and apoptotic cells generated by the actions of IFN-alpha. The direct and deleterious impact on target tissues, the ability to induce an autoimmune response, and the potential for a self-sustaining cycle of induction and damage suggests that IFN-alpha could be a pivotal factor in the development of autoimmune diseases. This review will evaluate the rationale for, possible approaches to, and safety concerns associated with, targeting interferon alpha (IFN-alpha) as a therapeutic strategy for the treatment of autoimmune diseases. While the approach may be applicable to several autoimmune diseases, there will be an emphasis on systemic lupus erythematosus and insulin dependent diabetes mellitus.

Abstract
Activated protein C resistance (APCR), high tissue factor (TF) expression, and hyper-homocysteinemia are associated with thromboembolic diseases. Thromboembolism is a frequent complication of systemic lupus erythematosus (SLE). In this study, we evaluated the prevalence of APCR, high TF, and homocysteine with correlation of the thrombotic tendency in SLE. Ninety-four SLE patients and 28 normal controls were included. APC ratio and TF antigen were measured using commercial kits. Plasma homocysteine level was measured using HPLC. The prevalence of APCR, high TF antigen level, and hyper-homocysteinemia in our SLE patients were 21.3%, 66.0%, and 23.4%, respectively. The median plasma level of TF antigen in SLE patients was 145.23 pg/mL (range, 31.00-778.50 pg/mL), which was significantly higher than the control value of 39.83 pg/mL (range, 1.55-168.50 pg/mL). The median APC ratio in SLE patients was 2.76 (range, 1.48-13.47), which was significantly lower than the control value of 3.59 (range, 0.26-5.66). The plasma level of homocysteine was not significantly different from that of control. A significant association was observed between the presence of APCR (OR = 8.59, P < 0.0001) but not with the presence of high plasma TF antigen level (OR = 1.24, P = 0.67) and thrombotic complications in SLE patients. In conclusion, APCR and high plasma TF levels are common in SLE, but a significant association was observed only between the presence of APCR and thrombosis in SLE patients.

Abstract
Systemic Lupus Erythematosus (SLE) remains a challenging autoimmune disease in term of etiology, pathogenesis and treatment. It is estimated that 10-17% of lupus patients present before the age of 16. SLE in children appears to have more severe organ involvement than in adults. The outcome of childhood SLE has improved during the last decade, but the morbidity remains high.

Abstract
Glucocorticoids (GCs) are the most common group of medications used in the treatment of allergic and autoimmune disorders. They produce potent anti-inflammatory effects by inducing or repressing the expression of target genes. Although most patients with allergic diseases and autoimmune disorders respond to GC therapy, a small subset of patients demonstrate persistent tissue inflammation despite treatment with high doses of GCs. This condition results from an interaction between susceptibility genes, the host's environment, and immunologic factors. The treatment of these patients requires a systematic approach to rule out underlying conditions that lead to steroid resistance or treatment failure, as well as the use of alternative strategies to inhibit tissue inflammation.

Abstract
OBJECTIVE To demonstrate the association between autoantibodies to nuclear lamin B1 (aLB1) and protection against thrombosis ("thromboprotection") in patients with systemic lupus erythematosus (SLE), and to elucidate the mechanism by which aLB1 cause thromboprotection in vivo. Since a number of autoantigens in SLE have been localized specifically to the external surface of apoptotic blebs, it was hypothesized that circulating aLB1 may block the procoagulant effect of apoptotic blebs by binding to LB1 displayed at the external bleb surface. METHODS A cross-sectional study was performed using serum samples obtained at first evaluation of 259 English Canadian and French Canadian patients from SLE registries at 3 hospitals. A case-control study was performed to analyze the relationship between aLB1 and lupus anticoagulant (LAC) status and thrombotic manifestations between onset of disease and last followup. Reactivity of aLB1 with Jurkat or endothelial cells, which had been induced to undergo apoptosis, was determined by indirect immunofluorescence. Localization of LB1 in apoptotic cells and blebs was analyzed by confocal microscopy and surface labeling of cell membrane proteins. RESULTS High-titer aLB1 was restricted to a subset of SLE patients (46 patients), with an overall frequency of 17.8% (range 11.6-24.3% in the 3 centers). LB1 antibodies were significantly associated with LAC but not with antibodies to cardiolipin (aCL) or beta(2)-glycoprotein I (anti-beta(2)GPI). The frequency of thrombosis differed markedly depending on aLB1 and LAC status, as follows: presence of LAC and absence of aLB1 50%, presence of both LAC and aLB1 22.7%, absence of both LAC and aLB1 25.5%, absence of LAC and presence of aLB1, 20.8%. Further subclassification of patients based on aCL and anti-beta(2)GPI status revealed that, in the presence of LAC but in the absence of aCL, anti-beta(2)GPI, and aLB1, the frequency of thrombosis was 40%, whereas in the presence of aLB1, it decreased strikingly, to 9.1%. LB1 was found to be translocated into surface membrane blebs during apoptosis and to be entirely enclosed within the apoptotic bleb plasma membrane of Jurkat and endothelial cells. CONCLUSION The presence of aLB1 in SLE patients with LAC essentially nullifies the strong prothrombotic risk associated with LAC. Hence, aLB1 is associated with thromboprotection. Reactivity of aLB1 with apoptotic blebs does not seem to play a direct role in mediating this protection, since LB1 is buried within apoptotic blebs and inaccessible to circulating aLB1. The mechanism by which aLB1 confers thromboprotection in SLE remains to be elucidated.

Abstract
In the past decade, there has been enormous progress in the understanding of the pathomechanisms of immune-mediated diseases, which has led to major advances in immunotherapeutic strategies. As a consequence, the armamentarium of specific and nonspecific immune-modulating and immunosuppressive drugs for the treatment of skin diseases has been widely extended. Among the nonspecific immunomodulators, mycophenolate mofetil and leflunomide show promising effects in a variety of autoimmune and inflammatory skin disorders. Both compounds inhibit a key enzyme in nucleotide biosynthesis, a step that is pivotal for the production of cytotoxic T cells and antibody formation. They do not act in the nucleus, which may explain their advantageous side-effect profile.

Abstract
SLE causes significant morbidity and mortality by multisystem organ involvement. Infections are the leading cause of morbidity and mortality in patients with SLE. Meticulous exclusion of infection is mandatory in patients with SLE, because infections may masquerade as exacerbation of underlying disease; and the immunosuppression used to treat severe forms of exacerbation of lupus can have catastrophic consequences in patients with infections. Corticosteroids are the first-line therapy for most noninfectious complications of SLE, with various adjuvant immunosuppressive agents such as cyclophosphamide being increasingly used in combination with plasmapheresis. Some recent series have shown an improved survival rate, but this improvement needs to be confirmed by further studies. Controlled trials comparing various therapeutic options are lacking, and optimal therapy has not been defined.

Abstract
Antiphospholipid antibody syndrome has been associated with vascular thrombosis, thrombocytopenia, hemolytic anemia, livedo reticularis, neurologic disorders, and recurrent fetal loss. The diagnosis of antiphospholipid syndrome is given in the presence of an elevated anticardiolipin antibody lupus anticoagulant in addition to a thrombotic event. Antiphospholipid antibodies are responsible for a majority of thrombotic events in children. These antibodies can present as a primary syndrome or secondary to other diseases, such as systemic lupus erythematosus. Anticoagulation therapy with heparin and low-dose aspirin is the recommended treatment in pediatric patients.

Abstract
OBJECTIVE To review the presenting symptoms, possible complications, treatment options, and reproductive considerations for rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, and Sjogren's syndrome. DATA SOURCES Articles retrieved from MEDLINE and OVID using the search terms women and female in combination with autoimmune disease, rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, and Sjogren's syndrome. References identified from citations in these articles were also reviewed. DATA SYNTHESIS Autoimmune rheumatic diseases are more common in women than in men and are most likely to manifest during the reproductive years. The reasons for this incidence pattern remain unclear but appear to be related to sex hormones and microchimerism. These diseases have varied clinical presentations that may be local or systemic and range from mild to severe. There is no cure for these autoimmune rheumatic diseases; treatments focus on managing symptoms. Many of the agents used for treating these diseases are contraindicated in pregnancy, posing special considerations for women who develop these diseases during their childbearing years. CONCLUSION Knowledge of the presenting symptoms of, treatment options for, and reproductive considerations with these diseases is important for pharmacists who counsel women with them.

Abstract
The number of pregnant women receiving immunosuppressants for anti-rejection therapy or autoimmune diseases is increasing. All immunosuppressive drugs cross the placenta, raising questions about the long-term outcome of the children exposed in utero. There is no higher risk of congenital anomalies. However, an increased incidence of prematurity, intrauterine growth retardation (IUGR) and generally low birth weight has been reported, as well as maternal hypertension and preeclampsia. The most frequent neonatal complications are those associated with prematurity and IUGR, as well as adrenal insufficiency with corticosteroids, immunological disturbances with azathioprine and cyclosporine, and hyperkalemia with tacrolimus. The long-term follow-up of infants exposed to immunosuppressants in utero is still limited and experimental studies raise the question whether there could be an increased incidence at adult age of some pathologies including renal insufficiency, hypertension and diabetes.

Abstract
Regulation of calcium homeostasis during pregnancy is complex. Clinically significant bone mass loss is infrequent; however a subset of women may develop symptomatic osteoporosis related to pregnancy. Lactation is a period of special risk for bone loss. Whatever the effect of heparin on bone loss, vertebral fractures are rare in women treated with heparin during pregnancy. Low molecular weight heparins may have a less deleterious effect on bone than unfractionated heparin. Women with autoimmune diseases, particularly those with lupus and/or the antiphospholipid syndrome may receive heparin throughout pregnancy. Corticosteroids must be reduced as much as possible in these women, and calcium plus vitamin D are recommended. Finally, indications for heparin use must be clearly justified and advice regarding breastfeeding must be offered.

Abstract
Both systemic lupus erythematosus and Sjogren's syndrome are autoimmune diseases. Almost all organs can be involved but the gall bladder is an unusual site. We report a 39-year-old woman with systemic lupus erythematosus and Sjogren's syndrome presenting with acute acalculous cholecystitis. It is a very rare complication and, in the literature review, surgical interventions are mostly applied for treatment. In our case, high dose corticosteroid was tried and clinical manifestations and radiologic findings were improved.

Abstract
True (cofactor-independent) anticardiolipin antibodies (aCL) are thought to lack lupus anticoagulant (LA) activity and pathogenic potential. A serum monoclonal immunoglobulin Mlambda (mIgMlambda) with aCL and LA activities found in a man with a splenicIgMlambda+ B-cell lymphoplasmacytic lymphoma (LPL) without thrombotic events has been characterized. LPL-derived hybridoma clones (designated HY-FRO) producing the serum mIgMlambda were obtained. mIgMlambda secreted by HY-FRO grown in protein-free culture medium, like that purified from serum, (i) showed binding, in a cofactor-free system, to solid-phase CL and phosphatidylserine (PS) and to the membrane of PS-expressing cells (apoptotic cells and activated platelets); (ii) failed to bind neutral phospholipids (PL), beta2Glycoprotein, histone, ssDNA, dsDNA, human IgG and umbilical vein endothelial cells. Absorption with apoptotic cells abolished its binding to anionic plate-bound CL and PS. IgMlambda-FRO used poorly mutated VH and Vlambda region genes, with a pattern that was inconsistent with an antigen-driven selection. Basic amino acids were present in the IgH complementarity determining region 3 (CDR3), which can be important for binding to anionic PL. These findings demonstrate unequivocally that true anti-anionic PL IgM antibodies can exert LA and indicate this anti-PL type does not involve thrombophilia.

Abstract
The revival of thalidomide began shortly after the drug was withdrawn from the market because of its teratogenic properties. Therapeutic effects of thalidomide were found accidentally in leprosy patients with erythema nodosum leprosum (ENL). Subsequent research widened the understanding of the activity of thalidomide, and with improved methodology and the augmented background knowledge of immunology it was possible to interpret the properties of thalidomide more coherently. Effects on tumour necrosis factor-alpha (TNFalpha) release play an important role in the ability of thalidomide to affect the immune system. Alteration of synthesis and release of cytokines such as interleukin (IL)-1, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12 and interferon-gamma is involved in the complex mechanisms of thalidomide. Thalidomide targets leucocytes, endothelial cells and keratinocytes, affecting them in a different manner and at different cellular levels. Changes in the density of adhesion molecules alter leucocyte extravasation and the inflammatory response in the tissue involved. Several mechanisms for the teratogenic action of thalidomide are currently under review, but this mode of action of the drug still remains unclear and we review evidence-based hypotheses for the teratogenicity of thalidomide. Thalidomide shows significant clinical impact in several diseases such as ENL in lepromatous leprosy, chronic graft-versus-host disease, systemic lupus erythematosus, sarcoidosis, aphthous lesions in HIV infection, wasting syndrome in chronic illness, inflammatory bowel disease, multiple myeloma and some solid tumours. In 1998 the US Food and Drug Administration approved thalidomide exclusively for the treatment of ENL, and strict conditions were stipulated for its use in order to prevent teratogenic adverse effects. However, despite the promising findings of thalidomide at the molecular level, namely its anti-TNFalpha properties and its intercalation with DNA, and activity in clinical trials, there is still a great need for more intensive research.

Abstract
Systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS) can be associated with significant morbidity in children and adolescents. Renal involvement in SLE appears to be more severe and more frequent in the pediatric age group, with the major predictors for poor outcome being the severity of histopathologic lesions, severity of renal impairment at diagnosis, and hypertension. In addition to currently recognized cardiovascular and pulmonary involvement, accelerated atherosclerosis is of increasing concern in young individuals with SLE, because of both disease effects and medication usage. Neuropsychiatric SLE seen in childhood ranges from subtle cognitive dysfunction to severe central nervous system involvement; however, there is controversy over the value of different diagnostic studies. APS in children may be associated with SLE, idiopathic, or associated with viral infections. Systemic anticoagulation is recommended for patients with thrombotic events, but long-term management has not been well studied in children.
