Our objective is to clarify relationship between reversible cerebral vasoconstriction syndrome and administrating etanercept during puerperium. Several lines of evidence have suggested tumor necrosis factor (TNF) as a mediator of vascular dysfunction associated with estrogen deficiency. A 32-year-old woman resumed etanercept (25 mg/week), a TNF inhibitor, which had been discontinued during pregnancy, because of the deterioration of rheumatoid arthritis. She was admitted to our hospital with upper right quadrant blindness and mild right hemiparesis accompanied by pulsating left occipital pain, which had appeared 4 hours after restarting etanercept (25 mg/week)...

Pamapimod (PAM) is a novel selective p38 mitogen-activated protein (MAP) kinase inhibitor proved to be effective in rheumatoid arthritis in phase 2 clinical trial. However, its effect on osteoclast-associated osteoporosis and the underlying mechanisms remain unclear. In this study, we showed that PAM suppressed receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclast formation via inhibition of p38 phosphorylation and subsequent c-Fos and nuclear factor of activated T cells c1 (NFATc1) expression...

Cell death-associated neutrophil extracellular trap formation (NETosis) occurs during various autoimmune diseases including systemic lupus erythematosus and rheumatoid arthritis, as well as during gestation. Although increasing estrogen concentrations associated with pregnancy might induce NETosis via nuclear estrogen receptor (ERα/ERβ), little is known about the mechanisms associated with estrogen-induced NETosis. Here, we investigated the effects of estrogen (17-β-estradiol; E2) on NETosis, focusing on mechanisms associated with estrogen membrane receptor (GPR30) in neutrophil-like HL-60 cells...

Degeneration of the intervertebral disc (IVD), which consists of the annulus fibrosus (AF) and nucleus pulposus (NP), is a multifactorial physiological process associated with lower back pain. Despite decades of research, the knowledge of the underlying molecular mechanisms of IVD degeneration (IDD) has remained limited. The present study aimed to reveal the differential gene expression patterns in AF and NP during the process of IDD and to identify key biomarkers contributing to these differences. The microarray dataset GSE70362 containing 24 AF and 24 NP samples was retrieved from the Gene Expression Omnibus database...

Fibromodulin (FMOD) is one of the small leucine-rich proteoglycans. A search of the literature did not reveal any paper that specifically reviews the potential clinical applications of FMOD in the management of human diseases. First, the structure and physiological functions of FMOD were reviewed. Then its potential clinical applications in various diseases including diseases of the skin, tendons, joints, intervertebral discs, blood vessels, teeth, uterus, bone and kidney were reviewed. FMOD is able to switch the adult response to skin wounding to the desired fetal response of scarless healing...

Estrogens, in particular 17β-estradiol (E2), have a strong influence on the immune system and also affect pathological conditions such as autoimmune diseases. The biological effects of E2 are mediated by two intracellular receptors, i.e., estrogen receptor (ER)α and ERβ, which function as ligand-activated nuclear transcription factors producing genomic effects. Immune cells express both ERα and ERβ that play a complex role in modulating inflammation. Phytoestrogens display estrogen-like effects. Among them, silibinin, the major active constituent of silymarin extracted by the milk thistle ( Silybum marianum ), has been suggested to have an ERβ selective binding...

BACKGROUND: To identify the risk factors and changes of quality of life in the first occurrence of hip fracture in Taiwanese postmenopausal women. METHODS: In this case-control study, we enrolled 100 postmenopausal women with accidental first-incident hip fracture and 100 women without hip fracture. The control group was matched to the study group according to age. Evaluation consisted of a questionnaire, an interview to both assess quality of life via a 36-item Short Form Health Survey and document risk factors, a physical examination to record height and body weight, and bone mineral density (BMD) of the hip and spine using dual-energy X-ray absorptiometry (DXA)...

Cardiology, dermatology, and rheumatology form a fascinating triad. Many skin and joint disorders are associated with cardiovascular comorbidities because they share etiologic elements. Female predominance is often remarkable and likely related to autoimmune pathology. Although studies have shown that X-encoded genes may be involved in the differences in immunity between males and females, other studies have also shown that sex chromosomes are irrelevant and that estrogens and androgens are responsible for the differences...

Rheumatoid arthritis (RA) is a systemic autoimmune disease caused by both genetic and environmental factors. Recently, investigators have focused on the gut microbiota, which is thought to be an environmental factor that affects the development of RA. Metabolites secreted by the gut microbiota maintain homeostasis in the gut through various mechanisms [e.g., butyrate, which is one of the major metabolites of gut microbiota, exerts an anti-inflammatory effect by activating G-protein-coupled receptors and inhibiting histone deacetylases (HDACs)]...

BACKGROUND: Rheumatoid arthritis (RA) preferentially affects women, with the peak incidence coinciding with estrogen decrease in menopause. Estrogen (E2) may therefore have intrinsic immune-regulatory properties that vanish with menopause. Fc sialylation is a crucial factor determining the inflammatory effector function of antibodies. We therefore analyzed whether E2 affects immunoglobulin G (IgG) sialylation. METHODS: Postmenopausal (ovariectomized) mice were immunized with ovalbumin and treated with E2 or vehicle...

The female preponderance of many autoimmune diseases suggests a possible hormonal etiology. Little research exists on systemic and organ-specific autoimmune diseases and risk of breast cancer by tumor estrogen receptor (ER)- and progesterone receptor (PR)- status. Here, we evaluate associations between selected systemic and organ-specific autoimmune diseases and breast cancer risk overall and by tumor ER- and PR-status. We used linked Surveillance, Epidemiology and End Results (SEER)-Medicare data, with first female breast cancer cases ages ≥66 years identified by SEER registries (years 1992-2011; N = 209,929)...

This review describes the important functional implications of TCL1A single nucleotide polymorphisms (SNPs) discovered during pharmacogenomic studies of aromatase inhibitor-induced musculoskeletal adverse events that were subsequently shown to influence the expression of cytokines, chemokines, toll-like receptors (TLR), and NF-κB in a SNP and estrogen-dependent fashion. Functional genomic studies of these SNPs led to the discovery of novel mechanisms that may contribute to disease pathophysiology and which may also increase our understanding of pharmacogenomic aspects of regulation of the expression of inflammatory mediators...

BACKGROUND: Hormonal fluctuations during menopause lead to endocrine changes in women, especially in their sex steroid hormone production. Studies have documented the role of estrogen and progesterone (Pg) on autoimmune disorders such as multiple sclerosis, systemic lupus erythematosus, and rheumatoid arthritis. Lichen planus (LP), an autoimmune disorder, seen frequently in perimenopausal women, may also get affected by sex steroid hormones, but no direct relationship has been established yet...

Rheumatoid arthritis (RA) is characterized, among other factors, by systemic bone loss, reaching ~50% prevalence of osteoporosis in postmenopausal women. This is roughly a doubled prevalence in comparison with age-matched non-RA women. Postmenopausal RA women are more likely to be sero-positive for the anti-citrullinated peptide antibody (ACPA). Our extensive review of recent scientific literature enabled us to propose several mechanisms as responsible for the accelerated bone loss in ACPA(+) RA postmenopausal women...

AIM: A more vigorous immune system activation is generally seen in women as compared to men. The reasons for these differences are still not understood. By investigating the immune-regulatory role of estrogens, we have previously shown that estradiol (E2) can regulate and ameliorate rheumatoid arthritis models. The aim of this study was to elucidate the role of ovariectomy (ovx) and estradiol (E2) in innate immune responses. METHODS: Female mice were ovx or sham operated...

OBJECTIVE: Estriol is the main estrogen in pregnancy, but has received less attention outside gestation. It is well known that pregnancy has an immunosuppressive effect on many autoimmune diseases such as multiple sclerosis, psoriasis, thyroiditis, uveitis, and rheumatoid arthritis. Emerging evidence indicates that estriol has potential immunomodulatory benefits for many disease states including autoimmune, inflammatory, and neurodegenerative conditions. In this review, we discuss emerging roles for estriol in the treatment of menopausal symptoms, osteoporosis, cancer, hyperlipidemia, vascular disease, and multiple sclerosis...

We studied functional effect of rs12722489 single nucleotide polymorphism located in the first intron of human IL2RA gene on transcriptional regulation. This polymorphism is associated with multiple autoimmune conditions (rheumatoid arthritis, multiple sclerosis, Crohn's disease, and ulcerative colitis). Analysis in silico suggested significant difference in the affinity of estrogen receptor (ER) binding site between alternative allelic variants, with stronger predicted affinity for the risk (G) allele. Electrophoretic mobility shift assay showed that purified human ERα bound only G variant of a 32-bp genomic sequence containing rs12722489...

IL-18BP is a natural antagonist of pro-inflammatory IL-18 cytokine linked to autoimmune disorders like rheumatoid arthritis. However, its role in post menopausal osteoporosis is still unknown. In this study, we investigated the role of IL-18BP on murine osteoblasts, its effect on osteoblasts-CD4+ T cells and osteoblasts-CD11b+ macrophage co-culture. mIL-18BPd enhances osteoblast differentiation and inhibits the activation of NLRP3 inflammasome and caspase-1 which process IL-18 to its active form. Using estrogen deficient mice, we also determined the effect of mIL-18BP on various immune and skeletal parameters...
