Filter by:Women with systemic lupus erythematosus (SLE) have a high risk of placenta-mediated complications, which can lead to substantial cardiac morbidities in affected women and their offspring. In addition, maternal autoantibodies, which are actively transferred across the placenta during pregnancy, can affect the cardiovascular health of SLE offspring. Hydroxychloroquine (HCQ) is effective in preventing adverse pregnancy outcomes in SLE and might be beneficial in preventing fetal cardiovascular damage mediated by maternal autoantibodies. However, there are concerns that HCQ might cause maternal and neonatal cardiac toxicity. A novel imaging technique (i.e. speckle tracking echocardiography), which allows early identification of cardiac dysfunction, has proven superior to any other in assessing cardiac function in mothers and neonates experiencing placenta-mediated complications and in identifying drug cardiotoxicity. Yet, there has been no study using speckle tracking echocardiography to evaluate the cardiovascular health of pregnant SLE women and their offspring, as well as the potential adverse cardiac effect of HCQ. Moreover, due to unavailability of assays, HCQ dosing in SLE is generally done blindly, without checking drug levels. To fill these key knowledge gaps, the investigators aim to: 1) assess the impact of placenta-mediated complications on maternal and neonatal cardiac function, 2) evaluate if HCQ exposure (as measured by whole-blood levels) is associated with maternal and neonatal outcomes including cardiac toxicity, and 3) determine the effect of maternal autoantibodies on neonatal cardiac function. Ultimately, our proposal will help optimize reproductive and cardiovascular outcomes in lupus women and their offspring.
The aim of this research project is to better understand the origin and clinical significance of two lupus-specific "genetic signatures" (IFN signature and plasma cell signature) in patient subgroups with well-defined clinical characteristics. Our aim is to correlate these genetic signatures with cell activation profiles and the production of specific cytokines in different populations from whole blood and in short-term cultures of these circulating cells.
Background: People with systemic lupus erythematosus (SLE) are at risk of developing complications in their blood vessels. This can increase the risk of heart attacks or stroke. No medications have been effective at reducing this risk in people with lupus. Objective: To test whether a drug (anifrolumab) can improve blood vessel function and reduce blood vessel inflammation in people with SLE. Eligibility: People aged 18 to 80 years with SLE. Design: Participants will undergo screening. They will have a physical exam. They will have blood and urine tests. They will have a test of their heart function and a chest X-ray. They will answer questions about their SLE symptoms. Participants will visit the clinic 9 times in 8 months. After screening, visits will be 4 weeks apart. Each visit may take up to 4 hours. Participants will receive infusions from a tube attached to a needle inserted into a vein in the arm (IV). Some will receive anifrolumab. Others will receive a placebo treatment. They will not know which one they are getting. At some visits they will have additional tests: CAVI (cardio-ankle vascular index) tests blood vessel function. Participants will lie still for 20 minutes. Small electrodes will be placed on both wrists with stickers. A microphone will be placed on their chest. Blood pressure cuffs will be wrapped around their ankles and arms. FDG-PET/CT is an imaging procedure. Participants will receive a substance through an IV line. They will lie on a table for 110 minutes while a machine captures images of their body.
Dysbiosis, or disruption of the gut microbiota, leads to the onset of autoimmunity. Increasing data suggest that the gut microbiota is changed in various murine lupus models as well as in human systemic lupus erythematosus SLE patients. Ingestion of lactobacilli, which have immunoregulatory properties, may be a viable strategy for controlling disease development and progression in patients with lupus, such as increasing the remission period and decreasing flare frequency.
Part 1 : To evaluate the safety and tolerability of a single intravenous (IV) or subcutaneous (SC) dose of KK4277 in healthy Japanese or non-Asian adult males. Part 2 : To evaluate the safety and tolerability of repeated IV administration of KK4277 in patients with Systemic lupus erythematosus (SLE) or Cutaneous lupus erythematosus (CLE).
Systemic lupus erythematosus (SLE) is a severe autoimmune disease in which patients often develop numerous autoantibodies (Abs). Unfortunately, none of the SLE specific Abs described so far (anti-DNA, -C1q, -nucleosome) are correlated enough to the disease activity to be used as a useful biomarker and reliably help in the therapeutic decision. Abs effector functions, including antibody-dependent cell-mediated cytotoxicity (ADCC), antibody-dependent cellular phagocytosis (ADCP) and antibody-mediated complement activation, are conditioned by the structure of the crystallizable fragment (Fc) and especially the N-linked oligosaccharide structures attached to the asparagine-297 in the CH2 domain of the Fc region. It has been shown that the decrease in galactosylation, sialylation and fucolylation is generally associated with inflammatory function of circulating IgG whereas Abs with sialic acid, fucose and/or galactose in Asn-297 are anti-inflammatory. This major role of Ab glycosylation in the regulation of the effector and pathogenic functions of Abs have been well documented in rheumatoid arthritis and ANCA associated vasculitis with a good correlation between Ab sialylation and disease activity. In lupus, it has been shown that glycosylation of total IgG is also altered and correlated with disease activity but glycosylation analysis of the LES specific Abs is still lacking. The aim of this study is to analyse by mass spectrometry (MS) the different glycoforms of anti-DNA Abs in lupus patients and find a correlation with disease activity.
systemic lupus erythematosus (SLE) is the most common autoimmune disease in women of childbearing age. Promoting physical activity is a major national priority for the general population, including patients with chronic diseases. The aim of this study is to investigate the efficiency of combined effect of progressive resisted exercise with aerobic exercise for bone mineral density, quality of life, muscle strength and physical activity for patients with SLE.

In 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.
Lupus nephritis (LN) may affect approximately half of patients with Systemic Lupus Erythematosus (SLE). LN is a major cause of morbidity and the most important predictor of mortality in patients with SLE. Some 5-20% of patients with LN may develop end-stage renal disease within 10 years of follow-up from the time of diagnosis. Other studies have described progression to end-stage renal disease in 10-30% of patients with LN. The European League Against Rheumatism, the European Renal Association and the European Dialysis and Transplant Association have recently updated their recommendations for the management of LN. These recommend the use of intravenous (IV) methylprednisolone boluses followed by lower doses of oral glucocorticoids (GC) and place mycophenolate mofetil (MMF) and the European regimen of cyclophosphamide (CYC) as the immunosuppressive drugs of first choice, with the IV CYC regimen for certain more aggressive cases. They also consider the use of "multitarget therapy" based on the combination of tacrolimus (TAC) and MMF and GC in patients with proteinuria in the nephrotic range who have not responded to the first line of treatment. For refractory active renal disease, they recommend as an alternative the use of rituximab (RTX) 1000 mg IV repeated after 15 days. Belimumab has been shown to be significantly more effective than placebo in the treatment of patients with active LN. This finding will lead to positioning belimumab in the therapeutic algorithm for LN. However, in clinical practice these immunosuppressive drugs are not always effective in the treatment of LN, and even one in 3 patients with an initial favorable response may experience renal recurrence. The choice of the appropriate treatment for LN and its early initiation are key to improve the prognosis of these patients and to avoid progression to chronic renal failure. The identification of biomarkers capable of predicting the response (or lack thereof) to one or another therapy at the time of LN diagnosis would allow to implement precision medicine, thus constituting a revolution in the treatment of patients with LN. Allows more targeted treatments with greater specificity to be established. The objective of this project is to analyze histopathological biomarkers in the renal biopsy to predict the renal response to the different drugs used in the treatment of LN. This would contribute to a more specific and cost-effective therapeutic strategy.
