BACKGROUND AND OBJECTIVE: Venetoclax is an oral selective Bcl-2 inhibitor approved for the treatment of patients with chronic lymphocytic leukemia with 17p deletion. Mechanistic and preclinical evidence warranted evaluation of venetoclax for the treatment of systemic lupus erythematosus (SLE). This work characterized the pharmacokinetics of venetoclax in female subjects with SLE. METHODS: Single (10-500 mg) and multiple (30-600 mg) escalating doses of venetoclax or matching placebo were evaluated using randomized, double-blind, placebo-controlled designs (6 active and 2 placebo per dose with 73 unique SLE patients enrolled, 25 of whom enrolled twice)...

Systemic lupus erythematosus (SLE) or Lupus is a chronic and idiopathic autoimmune connective tissue disease that involves several organs and organ systems. SLE may lead to a group of psychiatric manifestations, including delirium, anxiety disorders, cognitive dysfunction, mood disorders, and psychosis, which are caused by organic or non-organic factors. In addition, it is thought that the most common cause of neuropsychiatric lupus is corticosteroid use; central nervous system involvement and inflammatory processes also have an important role in the development of psychiatric manifestations...

Objective Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can result in disability and psychological distress. Although pain has been associated with depressive symptomatology and stress in SLE, a paucity of theoretical models have been used to explain the relationship between pain and psychological distress in this population. Thus, the present study examined helplessness as a mediator of the relationship between pain and psychological distress among patients with SLE. Methods Multiple mediation analysis was used to examine the hypothesis that learned helplessness mediates the relationship between pain and symptoms of anxiety, depression, and stress in a sample of patients with SLE ( N = 136) receiving medical care at Cedars Sinai Medical Center...

Systemic lupus erythematosus (SLE) is a chronic systemic autoimmune inflammatory disease and early diagnosis is of clinical and therapeutic importance. Melatonin is an endogenous endolamine hormone that plays an important role in the immune system due to its anti-inflammatory action. This study was designed to assess serum melatonin levels in SLE patients and to evaluate the possible correlation between serum melatonin and patients' baseline characteristics. A case-control study was performed on 50 SLE patients (48 females and 2 males), diagnosed according to the revised 1997 ACR Criteria, and 25 healthy controls (24 females and 1 male), matched by age and sex...

Studying Klinefelter's syndrome (male 47,XXY) and triple X (female 4,7XXX), we propose that the number of X chromosomes mediates the female bias of systemic lupus erythematosus (SLE) and Sjögren's syndrome (SS). Our recent paper described SLE and SS patients with extremely rare X chromosome aneuploides in which distal Xp was triplicated, implicating genes lying on the short arm of X1 . Brooks points out that X-linked chronic granulomatosus disease (X-CGD) can also have gene duplication from Xp21.2 to Xp terminus, and some female carriers of X-CDG have a cutaneous lupus-like illness...

Inflammasomes are intracellular multiprotein complexes that coordinate anti-pathogenic host defense during inflammatory responses in myeloid cells, especially macrophages. Inflammasome activation leads to activation of caspase-1, resulting in the induction of pyroptosis and the secretion of pro-inflammatory cytokines including interleukin (IL)-1β and IL-18. Although the inflammatory response is an innate host defense mechanism, chronic inflammation is the main cause of rheumatic diseases, such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), ankylosing spondylitis (AS), and Sjögren's syndrome (SS)...

Ubiquitination is an important post-translational modification that regulates a myriad of biological processes such as inflammation, immune response, cell differentiation and proliferation. During the last decade, progress in proteomics contributed to the identification of new E3 ligases and their substrates. Hence, deregulated ubiquitination events are found to be involved in several inflammatory disorders, exemplifying by systemic lupus erythematosus (SLE), type 1 diabetes, rheumatoid arthritis (RA) and psoriasis...

Glomerulonephritis is one of the most serious manifestations of systemic lupus erythematous (SLE). Because SLE is ≥10 times more common in women, a role for estrogens in disease pathogenesis has long been suspected. Estrogen receptor α (ERα) is highly expressed in renal tissue. We asked whether ERα expression contributes to the development of immune-mediated nephropathies like in lupus nephritis. We tested the overall effects of estrogen receptors on the immune response by immunization with OVA and induction of chronic graft-versus-host disease in female ERα-knockout mice...

OBJECTIVES: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease of considerable genetic predisposition. Genome-wide association studies have identified tens of common variants for SLE. However, the majority of them reside in non-coding sequences. The contributions of coding variants have not yet been systematically evaluated. METHODS: We performed a large-scale exome-wide study in 5004 SLE cases and 8179 healthy controls in a Han Chinese population using a custom exome array, and then genotyped 32 variants with suggestive evidence in an independent cohort of 13 246 samples...

Serum Mac-2-binding protein (M2BP) is elevated in various chronic inflammatory diseases, and evidence suggests that glycosylation of M2BP induces discrete biological effects. However, the role of serum M2BP in systemic lupus erythematosus (SLE) is still unclear. Recently, a Wisteria floribunda agglutinin-positive-M2BP (WFA+-M2BP) immunoassay has shown promise in detecting highly glycosylated M2BP. In this study, by using WFA+-M2BP immunoassay, we measured serum M2BP in 203 SLE patients and evaluated its clinical significance...

Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease that affects many different organ systems, with excessive production of type I interferons (IFNs) and autoantibodies against nucleic acids as hallmarks. Activation of the type I IFN system in SLE is due to continuous stimulation of plasmacytoid dendritic cells by endogenous nucleic acids, leading to sustained type I IFN production. This is reflected by an overexpression of type I IFN-regulated genes or an IFN signature. Type I IFNs have effects on both the innate and adaptive immune systems, which contribute to both loss of tolerance and the autoimmune disease process...

Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease with a high prevalence in females of childbearing age. Pregnancy in SLE nowadays has favorable outcomes for the majority of women. However, flares of disease activity, preeclampsia, fetal loss, and preterm birth are well-known risks in such pregnancies. Anti-SS-A(Ro)/SS-B(La) antibodies put fetuses at risk for congenital heart block and neonatal lupus. Several risk factors for adverse pregnancy outcomes have been identified. Women with antiphospholipid antibodies or antiphospholipid syndrome and lupus nephritis represent a group with high risk for obstetric complications...

Systemic lupus erythematosus (SLE) is a chronic, systemic autoimmune disease characterized by autoantibody production, complement activation, and immune complex deposition. It predominantly affects young and middle-aged women. While improvements in the diagnosis and treatment of SLE have altered prognosis, morbidity and mortality rates remain higher than the general population. In addition to renal injury, cardiovascular disease, and infection, malignancy is known to be a significant cause of death in this population...

Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease characterized by autoantibodies directed against numerous self-nuclear antigens. Because of the heterogeneous nature of lupus, it has been challenging to identify markers that are sensitive and specific enough for its diagnosis and monitoring. However, with the sequencing of the human genome, rapid development of high-throughput approaches has allowed for a better understanding of the etiopathogenesis of complex diseases, including SLE...
