Prediction of Lupus Renal Flares Study
Systemic Lupus ErythematosusIn patients with systemic lupus erythematosus, urinary CD4+ T cells may have the potential to predict subsequent renal flares in the next 6 months. Patients with systemic lupus erythematosus from our outpatient clinic will be included in this cross-sectional, prospective biomarker study regardless of disease activity, clinical phenotype, and disease duration or baseline therapy. Urinary T cells will be analyzed by flow cytometry. 6 months after sample collection a clinical follow-up will be conducted to assess the occurrence of either recurrent or de novo renal flares.
Osteoporosis and Fragility Fractures Among SLE Patients. (FRAIL Trial)
Lupus ErythematosusSystemicThe trial is designed to evaluate prevalence of fragility fracture, their impact on quality of life of SLE patients and disease or treatment variables such as steroids dosage or use of specific drugs like hydroxychloroquine, DMARDs or belimumab. Patients will perform DXA evaluation, blood tests and PROs questionnaires. Moreover, the investigators want to correlate those variables to bone turnover markers and bone metabolism modulators. A secondary aim is also to assess the fracture risk of those patients as described by FRAX and DEFRA tools.
Duke Lupus Registry
Systemic Lupus ErythematosusCutaneous LupusLupus is a systemic autoimmune disease that can present with many varied symptoms, including joint pain, fevers, kidney disease, and rashes. Lupus can affect anyone, but it is most common in younger women. The Duke Lupus Registry will collect information and blood samples from patients with lupus (systemic lupus erythematosus or cutaneous lupus) seen in the Duke Rheumatology clinics. The goal of this Registry is to understand how lupus changes over time so that we can improve the treatment of patients with lupus.

Serological and Urinary Biomarkers in Latin American Patients With Systemic Lupus Erythematosus:...
Lupus NephritisLupus nephritis (LN) is one of the main manifestationsin SLE patients, having an important impact on morbidity and mortality. Renal biopsy is the "gold standard" for the diagnosis of LN, however, it is an invasive technique, not free of complications,which is not recommended to be performed serially as a follow-up tool for patients with LN. Searching for biomarkers in SLE has been the subject of interesting research, although results have not always been relevant. Multiple biomarkers have been studied in different locations (soluble markers in blood, urine and biological fluids),of different nature(autoantibodies, genetic markers of "kidney damage") looking atdiagnostic and/orprognostic features. In recent years, several biomarkers have been developed that seek to find an association with pathological patterns, with pathogenic mechanisms and with a non-invasive diagnosis of different glomerulopathies, allowing the identification of prognostic subgroups in each type of kidney disease, while predicting response to treatment and/or recurrence. To date, double-stranded anti-DNA antibodies (anti-dsDNA) and serum complement are the only non-invasive routine biomarkers for monitoring renal activity in patients with LN. However, these markers are only the reflection of the immune activity of the disease and they are not markers of renal damage or poor prognosis. For all the above, the purpose of this study is, in a case-control study, to evaluate simultaneously serum (ANA, anti-dsDNA, anti-C1q, anti-cardiolipin IgG and IgM, anti-ß2GPI IgG and IgM, anti-phosphatidylserine/prothrombin antibodies, and anti-DFS70 antibodies) and urinary biomarkers, and the presence of anti-DFS70 antibodies, in a multiethnic cohort of patients with SLE such as the cohort of GLADEL, and assess its possible correlation with various socio-demographic, clinical and serological manifestations of the disease. In subgroup of patients, transcriptome studies will be performed using RNA from blood and tissue to identify possible transcriptional signatures.
Treatment and Clinical Outcomes Among SLE Patients in Pregnancy
Systemic Lupus ErythematosusPregnancy RelatedSystemic lupus erythematosus (SLE) is a kind of systemic autoimmune disease which can cause multiple organs and system damage, which often occurs in women of childbearing age. Compared with healthy pregnant women, SLE patients have higher incidence of premature delivery, preeclampsia and fetal loss during pregnancy. Since SLE patients usually have disease activity during pregnancy and postpartum, and a variety of maternal and fetal diseases are closely related to SLE, it is very important to monitor the disease activity and drug treatment of SLE patients during pregnancy.
The Prevalence Evaluation of Systemic Lupus Erythematosus in Russian Patients With Reproductive...
Systemic Lupus ErythematosusThis study will be a non-interventional prospective study. Assessment of parameters will be carried out as if the patient is treated in a real-life clinical setting. The patients should be enrolled into this project after evaluation of eligibility criteria by the investigator in clinical sites who have an experience in management of patients with SLE. No additional procedures besides those already used in the routine clinical practice will be applied to the patients. The purpose of this study is to estimate prevalence of confirmed SLE in patients in rheumatological settings who has the reproductive issues and certain clinical and laboratory manifestations specific for immunoinflammatory diseases in Russia. We will follow all the local regulatory requirements regarding adverse event reporting (pharmacovigilance). It is planned to enrol 2000 patients in clinical sites in Russian Federation (N ≤ 15). The study will include two visits. During the screening visit women who meet the inclusion/non-inclusion criteria will be offered to participate and sign the informed consent form (ICF). Initial patient's data input will be done retrospectively (case report forms [CRF] will be filled in, a patient's visit will be conducted in accordance with the routine practice and healthcare professionals (HCPs) recommendations on an individual basis). An experienced rheumatologist will collect the baseline patient's characteristics such as demographic data, clinical profile, detailed obstetric/reproductive history. Women who had pregnancies in the past will be asked about the course of all pregnancies and their outcomes. Women will be asked to provide the corresponding medical records or discharge summaries, if possible, in order to input the data from them into the CRFs (the documents will be given back to women at the same visit). The immunologic blood test will be conducted in the reference laboratory. According to clinical examination and laboratory test results (ANA, immunoassay for specific antibodies (anti-Sm, and-dsDNA), antiphospholipid antibodies (anticardiolipin antibodies, anti-β3GP1 antibodies, lupus anticoagulant, complement components C3, C4, etc.) SLE diagnosis will be made or rejected. One follow-up visit will be conducted for those women who were referred to a laboratory testing for SLE. The visit will include the laboratory analyses assessment by an experienced rheumatologist with a subsequent confirmation or rejection of the SLE diagnosis. The last date of enrolment - Dec 2023. Last patient last visit (approximately 4 months from the study start): patient's data input will be done for enrolled patients.
Neuron-specific Humoral and Cellular Immune Correlates of Structural and Functional Brain Connectomics...
Systemic Lupus ErythematosusSystemic lupus erythematosus (SLE) is the prototype systemic autoimmune disease. Neuropsychiatric SLE (NPSLE) is a major cause of morbidity. Its pathophysiology remains unclear and target autoantigens have not yet been identified. Site- specific autoantigen expression might correlate with imaging abnormalities. Based on existing expertise on the use of peptide/protein arrays and on antigen-specific T cell tracking, we plan to identify new fingerprints and targets for NPSLE. SLE patients +/- NPSLE and healthy subjects will undergo advanced magnetic resonance imaging. Three-dimensional data on structural or functional brain architecture will be integrated with brain transcriptome atlases and candidate antigens for autoreactive autoantibodies and T lymphocytes identified and validated. The evidence will add to current knowledge on NPSLE pathophysiology, provide new multimodal diagnostic tools for better patient care and a platform for innovative, personalized treatments.
