Updating the American College of Rheumatology revised criteria for the classification of systemic lupus erythematosus.
TL;DR: In 1992, Piette and colleagues suggested that the ACR revised criteria be reevaluated in light of the above discoveries, and the presence and clinical associations or antiphospholipid antibodies in patients with SLE was suggested.
Abstract: In 1982, the Diagnostic and Therapeutic Criteria Committee of the American College of Rheumatology (ACR)published revised criteria for the classification of systemiclupus erythematosus (SLE) (1). During the ensuing decade several investigators, including Drs. Graham Hughes and Donato Alarcon-Segovia, among others, have described the presence and clinical associations or antiphospholipid antibodies in patients with SLE, as well as the occurrence of theprimary antiphospholipid syndrome (2-5). In 1992, Piette and colleagues suggested that the ACR revised criteria be reevaluated in light of the above discoveries (6).

TL;DR: The 10-year mortality has improved and toxic adverse effects of older medications such as cyclophosphamide and glucocorticoids have been partially offset by newer drugs such as mycophenolate mofetil and glucose-sparing regimes.
Abstract: Systemic lupus erythematosus (SLE) is an autoimmune disease that can affect many organs, including the skin, joints, the central nervous system and the kidneys. Women of childbearing age and certain racial groups are typically predisposed to developing the condition. Rare, inherited, single-gene complement deficiencies are strongly associated with SLE, but the disease is inherited in a polygenic manner in most patients. Genetic interactions with environmental factors, particularly UV light exposure, Epstein-Barr virus infection and hormonal factors, might initiate the disease, resulting in immune dysregulation at the level of cytokines, T cells, B cells and macrophages. Diagnosis is primarily clinical and remains challenging because of the heterogeneity of SLE. Classification criteria have aided clinical trials, but, despite this, only one drug (that is, belimumab) has been approved for use in SLE in the past 60 years. The 10-year mortality has improved and toxic adverse effects of older medications such as cyclophosphamide and glucocorticoids have been partially offset by newer drugs such as mycophenolate mofetil and glucocorticoid-sparing regimes. However, further improvements have been hampered by the adverse effects of renal and neuropsychiatric involvement and late diagnosis. Adding to this burden is the increased risk of premature cardiovascular disease in SLE together with the risk of infection made worse by immunosuppressive therapy. Challenges remain with treatment-resistant disease and symptoms such as fatigue. Newer therapies may bring hope of better outcomes, and the refinement to stem cell and genetic techniques might offer a cure in the future.

TL;DR: For patients with proliferative lupus nephritis, short-term therapy with intravenous cyclophosphamide followed by maintenance therapy with mycophenolate mofetil or azathioprine appears to be more efficacious and safer than long-term Therapy with intravenously cycloph phosphamide.
Abstract: Background Long-term therapy with cyclophosphamide enhances renal survival in patients with proliferative lupus nephritis; however, the beneficial effect of cyclophosphamide must be weighed against its considerable toxic effects. Methods Fifty-nine patients with lupus nephritis (12 in World Health Organization class III, 46 in class IV, and 1 in class Vb) received induction therapy consisting of a maximum of seven monthly boluses of intravenous cyclophosphamide (0.5 to 1.0 g per square meter of body-surface area) plus corticosteroids. Subsequently, the patients were randomly assigned to one of three maintenance therapies: quarterly intravenous injections of cyclophosphamide, oral azathioprine (1 to 3 mg per kilogram of body weight per day), or oral mycophenolate mofetil (500 to 3000 mg per day) for one to three years. The base-line characteristics of the three groups were similar, with the exception that the chronicity index was 1.9 points lower in the cyclophosphamide group than in the mycophenolate mofe...

TL;DR: SLE is associated with abnormal early B cell tolerance, and 25–50% of the mature naive B cells in SLE patients produce self-reactive antibodies even before they participate in immune responses as compared with 5–20% in controls.
Abstract: A cardinal feature of systemic lupus erythematosus (SLE) is the development of autoantibodies. The first autoantibodies described in patients with SLE were those specific for nuclei and DNA, but subsequent work has shown that individuals with this disease produce a panoply of different autoantibodies. Thus, one of the constant features of SLE is a profound breakdown in tolerance in the antibody system. The appearance of self-reactive antibodies in SLE precedes clinical disease, but where in the B cell pathway tolerance is first broken has not been defined. In healthy humans, autoantibodies are removed from the B cell repertoire in two discrete early checkpoints in B cell development. We found these checkpoints to be defective in three adolescent patients with SLE. 25-50% of the mature naive B cells in SLE patients produce self-reactive antibodies even before they participate in immune responses as compared with 5-20% in controls. We conclude that SLE is associated with abnormal early B cell tolerance.

TL;DR: Studies of patients with systemic lupus erythematosus and of murine models of the disease have provided information regarding the different types of antibodies to DNA, their role in pathogenesis, and new subgroups of these antibodies are pathogenic.
Abstract: Antibodies to DNA are of interest to a broad spectrum of physicians and other scientists. The presence of large amounts of serum antibodies to double-stranded DNA is specific for systemic lupus erythematosus, and some subgroups of these antibodies are pathogenic. It is likely that people are predisposed to have systemic lupus erythematosus if they can make pathogenic subgroups of antibodies to DNA and if they cannot down-regulate them appropriately. Studies of patients with systemic lupus erythematosus and of murine models of the disease have provided information regarding the different types of antibodies to DNA, their role in pathogenesis, and new . . .

TL;DR: The 1971 preliminary criteria for the classification of systemic lupus erythematosus (SLE) were revised and updated to incorporate new immunologic knowledge and improve disease classification and showed gains in sensitivity and specificity.
Abstract: The 1971 preliminary criteria for the classification of systemic lupus erythematosus (SLE) were revised and updated to incorporate new immunologic knowledge and improve disease classification. The 1982 revised criteria include fluorescence antinuclear antibody and antibody to native DNA and Sm antigen. Some criteria involving the same organ systems were aggregated into single criteria. Raynaud's phenomenon and alopecia were not included in the 1982 revised criteria because of low sensitivity and specificity. The new criteria were 96% sensitive and 96% specific when tested with SLE and control patient data gathered from 18 participating clinics. When compared with the 1971 criteria, the 1982 revised criteria showed gains in sensitivity and specificity.

TL;DR: This study shows that properly performed ELISA or SRIA assays can be used to provide an accurate, reproducible, and quantitative measure of IgG and IgM aCL concentration in serum samples.
Abstract: Thirty laboratories from institutions in Britain, France, Italy, The Netherlands, New Zealand, Sweden and the USA participated in a workshop to evaluate the anti-cardiolipin (aCL) test. Participants were asked to measure IgG and IgM aCL in seven samples on each of three separate days. The seven samples were prepared so that IgG and IgM aCL concentrations were known before distribution. Twenty-three of 30 laboratories measuring IgG aCL had significant regression slopes (P less than 0.001) when optical absorbance readings or counts per minute were compared with IgG aCL concentration. Twenty-four of 28 laboratories measuring IgM aCL had significant regression slopes (P less than 0.001). Coefficient of determination (R2) ranged from 81.1% to 98.7% for laboratories with valid IgG aCL assays and from 48.0% to 96.7% for valid IgM aCL assays. Valid assays had in common the use of 10% fetal calf or 10% adult bovine serum in PBS. Assays that were not valid had in common the use of PBS, PBS-Tween, or 0.3% gelatin as diluents. All laboratories with valid assays defined samples with high and moderate aCL levels as positive but there was no consensus about low positive samples. This study shows that properly performed ELISA or SRIA assays can be used to provide an accurate, reproducible, and quantitative measure of IgG and IgM aCL concentration in serum samples.
