ABSTRACT Gut microbiota dysbiosis has been observed in a number of autoimmune diseases. However, the role of the gut microbiota in systemic lupus erythematosus (SLE), a prototypical autoimmune disease characterized by persistent inflammation in multiple organs of the body, remains elusive. Here we report the dynamics of the gut microbiota in a murine lupus model, NZB/W F1, as well as intestinal dysbiosis in a small group of SLE patients with active disease. The composition of the gut microbiota changed markedly before and after the onset of lupus disease in NZB/W F1 mice, with greater diversity and increased representation of several bacterial species as lupus progressed from the predisease stage to the diseased stage. However, we did not control for age and the cage effect. Using dexamethasone as an intervention to treat SLE-like signs, we also found that a greater abundance of a group of lactobacilli (for which a species assignment could not be made) in the gut microbiota might be correlated with more severe disease in NZB/W F1 mice. Results of the human study suggest that, compared to control subjects without immune-mediated diseases, SLE patients with active lupus disease possessed an altered gut microbiota that differed in several particular bacterial species (within the genera Odoribacter and Blautia and an unnamed genus in the family Rikenellaceae ) and was less diverse, with increased representation of Gram-negative bacteria. The Firmicutes / Bacteroidetes ratios did not differ between the SLE microbiota and the non-SLE microbiota in our human cohort. IMPORTANCE SLE is a complex autoimmune disease with no known cure. Dysbiosis of the gut microbiota has been reported for both mice and humans with SLE. In this emerging field, however, more studies are required to delineate the roles of the gut microbiota in different lupus-prone mouse models and people with diverse manifestations of SLE. Here, we report changes in the gut microbiota in NZB/W F1 lupus-prone mice and a group of SLE patients with active disease.

Background: Systemic Lupus Erythematosus (SLE) is a complex autoimmune disease characterized by the presence of autoantibodies against cell nuclei and involves many organ systems in the body. The etiopathology of SLE is thought to involve complex and multifactorial interactions between genetic variation and environmental factors. Hyperthyroidism is a disease due to increased thyroid hormone function followed by signs and symptoms that affect the body's metabolic system. Graves' disease is an autoimmune disease characterized by the presence of antibodies to TSHR (TRAb). Several coexisting autoimmune diseases have been classified under different syndromes. Case Presentation: A woman, 29 years-old, came to office with complaint of chest palpitation. Patient had history of fever, joint pain, hair loss, and malar rash. Patient had been diagnosed with hyperthyroidism for 4 years and regularly taking propylthiouracil 100 mg and propranolol 10 mg. Titer ANA Test 1/100, Anti ds-DNA 68.08, C3-Complement 93 (N: 83-193), C4-Complement 11.2 (N: 15-57), Free T3 7.79 (N: 1.71-3.71), Free -T4 2.50 (N: 0.70-1.48), TSHs 0.0001 (N: 0.350-4.94), TRAb 3.38 (N: < 1.75). Patient was diagnosed with systemic lupus erythematosus (SLE) and graves’ disease. Patient treated with methimazole 10 mg, propranolol 10 mg, myfortic 360 mg, and methylprednisolone 4 mg. Conclusion: Autoimmune Polyendocrine Syndromes (APS) was at first characterized as different endocrine organ diseases related to an immune system disease in a subject. Hence, affiliation between illnesses in APS was noted not to be irregular but in specific combinations in which a few non-endocrine immune system diseases were moreover portion of the disorders.

Management Issues

Systemic lupus erythematosus (SLE) is a systemic, autoimmune disease that can affect any part of the body, causing the immune system to attack the body’s cells and tissue, and resulting in inflammation and tissue damage. It is characterized by the presence of autoreactive B and T cells and the production of a broad, heterogeneous group of autoantibodies (autoAb); the absence of a unique presentation makes its diagnosis difficult, even for qualified clinicians. Systemic Lupus Erythematosus focuses on providing a practical approach to the assessment and management of patients with this complex, multisystem, autoimmune disease, in order to improve the diagnosis and treatment of the disease and its complications. It provides detail on the history and epidemiology of SLE alongside comprehensive sections on clinical features, treatment, and special situations. As well as detailing the challenging management issues of SLE, this title provides an overview of the numerous investigations specific to the condition, assessment of disease activity, symptomatic treatment, patient education, and biologic therapies. A specific section on juvenile-onset systemic lupus erythematosus also provides the practising clinician with the knowledge needed to manage this distinct and aggressive stage of SLE.

Increased Risk

Background:Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that carries an increased risk for both viral illnesses and malignancies, including a greater risk for both human papilloma virus (HPV) infection and cervical cancer. Due to this increased risk, the American Society of Colposcopy and Cervical Pathology guidelines for SLE patients recommend more frequent cervical cancer screening. Few studies have examined patient characteristics associated with decreased cervical cancer screening in patients with autoimmune disease, specifically SLE.Objectives:To estimate cervical cancer screening rates in women with recently diagnosed SLE, and to identify characteristics associated with decreased screening.Methods:We identified women with an initial diagnosis of SLE in the United States MarketScan Commercial Claims and Encounter (CCAE, age 18-64) administrative claims database. We included patients with at least three claims with a lupus diagnosis (first and last at least >90 days apart), no lupus claims within the year before initial claim, and who had been on antimalarial drugs for at least 90 days. We excluded all patients with a previous claim for hysterectomy.Cervical cancer screening was ascertained using diagnosis and procedure codes within 1 year before and 2 years after the first SLE claim. Our covariates included the year of first SLE claim (2001-2014), age at first SLE claim, comorbidity score, insurance type, geographical region, and prescriptions for multiple types of corticosteroids. Control patients included age-matched females without autoimmune disease. Univariate comparison and multivariate logistic regression models were built to evaluate determinants of screening.Results:We included 4,316 SLE patients (median age 45) and 86,544 control patients. The screening rate in SLE patients was 73.4% vs 58.5% in the controls (P < 0.001). The screening rate was 71% in 2001, increased to 75% in 2004, then decreased to 70% in 2014 (trend P =0.005). In the multivariate model the following factors were associated with decreased cervical cancer screening: year of first SLE claim 2012-2014 versus 2001-2005 (odds ratio (OR) 0.67, 95% confidence interval (CI) 0.53 – 0.84, P < 0.001); older age 61-64 versus 21-30 (OR 0.27, 95% CI 0.19 – 0.39, P < 0.001); comorbidity score of ≥2 versus <2 (OR 0.71, 95% CI 0.6 – 0.83, P < 0.001); and use of corticosteroids for ≥ 90 days versus <90 days (OR 0.73, 95% CI 0.59 – 0.9, P = 0.003). Insurance type and geographical region were not associated with cervical cancer screening.Conclusion:About three quarters of women with SLE underwent cervical cancer screening within 3 years of their first lupus claim, at higher rates than controls. However, there was a concerning downward trend in screening rates in recent years. In addition, higher risk populations for cervical cancer (older age, increased comorbidities, and longer duration of corticosteroids) had lower screening rates. These findings highlight the need to enhance education for healthcare providers to improve utilization of screening in women with SLE at high risk of cervical cancer.Disclosure of Interests:Sebastian Bruera: None declared, Richard Zogala: None declared, Xiudong Lei: None declared, Xerxes Pundole: None declared, Hui Zhao: None declared, Sharon Giordano: None declared, Jessica Hwang Grant/research support from: MERCK grant funding unrelated to SLE., Maria Suarez-Almazor: None declared

Objective.To determine whether the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) is valid in identifying patients who had a clinically important overall improvement with no worsening in other descriptors/systems.Methods.Consecutive patients with systemic lupus erythematosus with active disease who attended the Lupus Clinic between 2000 and 2012 were studied. Based on the change in the total SLEDAI-2K scores on last visit, patients were grouped as improved, flared/worsened, and unchanged. Patients showing improvement were evaluated for the presence of new active descriptors at last visit compared with baseline visit.Results.Of the 158 patients studied, 109 patients had improved, 38 remained unchanged, and 11 flared/worsened at last visit. In the improved group, 11 patients had a new laboratory descriptor that was not present at baseline visit. In those 11 patients, this new laboratory descriptor was not clinically significant and did not require a change in disease management.Conclusion.The SLEDAI-2K identifies improvement in disease activity overall without concealing clinically important worsening.

The systemic lupus erythematosus (SLE), commonly known as Lupus, is a rare and complex multisystem autoimmune disease where one’s immune system is overactive, and the body attacks its organ systems. SLE is a historically old disease described already in antiquity; it is an example of a chronic disease with physical, psychological, financial, and social implications for individuals diagnosed. It has inspired medical and basic biological scientists that focus on molecular biology, basic immunology, immunopathology, clinical science, genetics, and epidemiology. The syndrome is real in its existence-although hidden behind obstacles, cumbersome for patients and clinicians, and rebellious for scientists. There is currently no cure for SLE. The goal of treatment is to ease symptoms. This article will review information on the general approach to SLE therapy, focusing on currently approved therapies and novel approaches that might be used in the future.

Gingival Overgrowth

Systemic lupus erythematosus is a systemic autoimmune disease that involves multi organs. Genetic, endocrine, immunological, and environmental factors influence the loss of immunological tolerance against self-antigens leading to the formation of pathogenic autoantibodies that cause tissue damage through multiple mechanisms. The gingival overgrowth can be caused by three factors: noninflammatory, hyperplastic reaction to the medication; chronic inflammatory hyperplasia; or a combined enlargement due to chronic inflammation and drug-induced hyperplasia. Drug-Induced Gingival Overgrowth is associated with the use of three major classes of drugs, namely anticonvulsants, calcium channel blockers, and immunosuppressants. Due to recent indications for these drugs, their use continues to grow.

SUMMARY OBJECTIVE To study the profile of associated autoimmune diseases in a series of patients with systemic lupus erythematosus (SLE) and see if such associations are linked to IgA deficiency. METHODS Two hundred eighty-one patients with SLE were studied for Ig A levels by nephelometry. Levels equal to or under 0.05g/dL were considered as IgA deficiency. Epidemiological and clinical data, including the presence of associated autoimmune diseases, were extracted from the patient’s charts. RESULTS Ig A deficiency was found in 6% of the patients. In 30.2% of SLE patients, there was at least one more autoimmune disease; Hashimoto thyroiditis and Sjögren’s syndrome were the most common. No association between the occurrence of associated autoimmune disease with IgA deficiency was found. CONCLUSIONS There is a high prevalence of autoimmune diseases associated with SLE. IgA deficiency does not affect the presence of these associations.
