Identification of Modifiable Sleep-related Factors in Patients With Systemic Lupus Erythematosus.

Background: Sleep quality is a key determinant of physical and mental health, with important implications for immune regulation, psychological well-being, and overall quality of life. In systemic lupus erythematosus (SLE), sleep disturbances are highly prevalent and have been associated with poorer clinical and psychosocial outcomes. However, the specific contribution of potentially modifiable behavioral and environmental factors to sleep quality in this population has been insufficiently investigated. Objectives: To analyze the association between modifiable lifestyle, behavioral, and environmental factors and sleep quality in adults with systemic lupus erythematosus. Methods: A multicenter cross-sectional observational study will be conducted. Approximately 250 adults with systemic lupus erythematosus from different regions of Spain will be included. The primary outcome will be sleep quality, assessed using the Pittsburgh Sleep Quality Index (PSQI). Independent variables will include sleep hygiene (Sleep Hygiene Index), physical activity (International Physical Activity Questionnaire-Short Form), substance use, sleep timing and regularity, napping habits, screen exposure, and bedroom environmental conditions. Secondary variables will include risk of obstructive sleep apnea (STOP-Bang questionnaire), daytime sleepiness (Epworth Sleepiness Scale), perceived stress (Perceived Stress Scale-10), as well as clinical, sociodemographic, and anthropometric variables. Expected results: To identify behavioral and environmental factors independently associated with poor sleep quality in individuals with systemic lupus erythematosus and to estimate the prevalence of poor sleep quality in the study sample.

Clinico-biological Collection to Investigate the Physiopathology of Systemic Autoimmune Diseases

The aim of this project is to start a biological and clinical collection of patients presenting systemic autoimmune disease. This collection will provide appropriate biological samples to identify new biomarkers and to be accessible to the medical, scientific and industrial communities for the identification of new therapeutic strategies

Cutaneous Lupus Registry

Approximately 1.4 million individuals in the United States have systemic lupus erythematosus, and about 85% of these individuals develop skin lesions at some point of their disease. Cutaneous lupus erythematosus represents the skin manifestations of systemic lupus erythematosus, and can appear in people with or without systemic lupus. It is a mentally, physically, and emotionally debilitating disease that affects both the quality of life and social well-being of those affected. The cause of cutaneous lupus is not completely understood, but likely includes multiple factors from our genes and the environment. Multiple genetic studies with small numbers of cutaneous lupus patients have been performed to determine which genes are associated with cutaneous lupus. This study aims to accumulate even larger numbers of patients to confidently identify genes and the proteins they encode that could contribute greatly to the formation of cutaneous lupus. The discovery of these genes and proteins would help not only uncover how cutaneous lupus forms, but also improve our abilities to diagnose this disease and predict its course, and stimulate new drug development.

Study Evaluating SC291 in Subjects With Severe r/r B-cell Mediated Autoimmune Diseases (GLEAM)

SC291-102 is a Phase 1 study to evaluate SC291 safety and tolerability, preliminary clinical response, cellular kinetics and exploratory assessments for subjects with severe autoimmune diseases.

The Role of Cytokines and Regulatory T Lymphocytes in Migraine Pathophysiology.

Migraine is a frequent and debilitating neurologic disorder. It is more frequent in women, and more prevalent in patients with autoimmune and/or inflammatory diseases such as multiple sclerosis (MS), rheumatoid arthritis (RA), Crohn's disease (CD), systemic lupus erythematosus (SLE) and endometriosis, whereas patients with long standing type 1 diabetes mellitus (T1DM) - an autoimmune but non inflammatory disease - seem to be less affected compared to the general population. Despite new migraine prevention treatments, a large number of patients remain unresponsive to currently available anti-migraine therapy and migraine pathophysiology remains unclear. Several peptides (calcitonin gene-related peptide (CGRP), pituitary adenylate cyclase activating peptide-38 (PACAP-38), vasoactive intestinal polypeptide (VIP)) and hormones (estrogens, prolactin) and the immune system play an important role in migraine pathophysiology. Among T lymphocytes, regulatory T (Treg) cells suppress inflammation. Studies have evidenced higher levels of inflammatory molecules (cytokines) in migraine patients and have suggested decreased proportions of Treg cells in migraine, as well as in MS, RA, CD and SLE, whereas inflammation declines and Treg levels seem increased in long-standing T1DM. Inflammation, which participates in migraine pain, seems to be a common factor for migraine and these diseases. However, these studies display conflicting results and further investigation is required to better understand the mechanisms behind migraine. In this study, the investigators will compare Treg levels, as well as identify Treg subpopulations and measure cytokine levels in migraine and migraine-free participants with and without an autoimmune/inflammatory disorder (MS, RA, CD, SLE, T1DM and endometriosis).

Treatment of Lupus Nephritis With Allogeneic Mesenchymal Stem Cells

The purpose of this study is to evaluate the safety and efficacy of mesenchymal stem cells (MSCs) obtained from bone marrow for the treatment of adults with active proliferative lupus nephritis. The objective of this study is to evaluate the efficacy of mesenchymal stem cells (MSCs) in achieving a full or partial response in the treatment of Lupus Nephritis (LN) during its induction period.

Teams Engaged in Accessible Mental Health Interventions for Lupus Erythematosus and Dermatomyositis Stress

The objectives of this study are to determine if the 'Teams Engaged in Accessible Mental Health Interventions for Lupus Erythematosus and Dermatomyositis Stress' (TEAM-LEADS) intervention is feasible and acceptable to adolescents and young adults with lupus and dermatomyositis and whether it can help reduce stress and promote cardiovascular health behaviors in these individuals.

Methyl-donor Nutrient Supplementation and Methylation Profile in Lupus Patients With Obesity

Dietary supplementation with methyl donors has been demonstrated to increase DNA methylation in leucocytes whereas a limited dietary intake of methyl donors was associated with DNA hypomethylation. Considering SLE disease, previously study showed that high doses of vitamin B6 and folate were associated with less severe SLE. Furthermore, some evidences reported a relatively high incidence of decreased serum B12 levels in rheumatic patients. This led to the suggestion that diets rich in methyl group donors could have beneficial effects on SLE.

Trial of Belimumab in Early Lupus

This two year study will evaluate the effects of giving belimumab (Benlysta) to patients with Early Lupus. Early lupus is a diagnosis of lupus within 2 years. Subjects will be randomized to receive belimumab or placebo during the first year. During the second year, subjects who were randomized to belimumab will be rerandomized to continue to receive belimumab or to receive placebo. The study will look at clinical effects as well as effects on the immune system.
