BACKGROUND/AIMS: The study aims to elucidate the roles of 1,25(OH)2D3 and vitamin D receptor (VDR) in the pathogenesis of rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) by regulating the activation of CD4+ T cells and the PKCδ/ERK signaling pathway. METHODS: From January 2013 to December 2015, a total of 130 SLE patients, 137 RA patients and 130 healthy controls were selected in this study. Serum levels of 1,25(OH)2D3 and VDR mRNA expression were detected by ELISA and real-time fluorescence quantitative PCR (RT-qPCR)...

The earliest record between sun exposure and skin disease goes back five millennia to the ancient Egyptians. The modern scientific era of medical light therapy and skin diseases started in 1877 when Downs and Blunt reported that exposure to light inhibited fungal growth in test tubes. Continuing research generated a growing medical interest in the potential the effects of light to treat and cure skin diseases considered as parasitic. This culminated in the awarding of the 1903 Nobel Prize in Medicine to Niels Finsen for his pioneering work showing that light could successfully treat cutaneous mycobacterium tuberculosis (lupus vulgaris), a disfiguring disorder common at the time...

Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disease. The vitamin D receptor (VDR) gene is a candidate gene for susceptibility to autoimmune disorders. To date, only a few studies concerned the association of the VDR gene polymorphisms with childhood-onset SLE.In this study, we aimed to investigate the BsmI polymorphisms in the VDR gene, for the first time in Egyptian children and adolescents with SLE, to determine whether this polymorphism could be a marker of susceptibility to or severity of SLE and we also measured the serum level of 25-hydroxyvitamin D (25[OH] D) to assess its relation to such polymorphism...

Fatigue impacts 80-90% of patients with systemic lupus erythematosus (SLE), and an incomplete understanding of fatigue mechanisms limits effective treatment. Disease activity indices and laboratory markers inconsistently correlate with fatigue severity in SLE populations. Identification of fatigue biomarkers has important implications for understanding pathogenesis and defining novel therapeutic targets, but a paucity of evidence exists for fatigue biomarkers in SLE. The evidence for adipokines, reduced glutathione, iron deficiency, and vitamin D as potential biomarkers for SLE-related fatigue are reviewed...

BACKGROUND: The emerging role of vitamin D in immunology and autoimmune disorders has been a worldwide interest in the last decade. Systemic lupus erythematosus (SLE) patients are particularly at a delicate position predisposing them to suffer from vitamin D deficiency due to the multiple risk factors accompanying the disease. Whether vitamin D deficiency is also involved as a risk factor for developing SLE and affecting its course is a considerable concern. OBJECTIVES: The objective of this study was to estimate the prevalence of vitamin D deficiency in SLE patients and its relation to disease...

In the last few decades a number of small, often largely unrecognized steps have fundamentally changed the management of systemic lupus erythematosus (SLE). The current goal is to stop all disease activity without long-term use of more than 5 mg prednisolone per day. Remission, i.e. absence of activity in the SLE activity score of choice, is the defined target in the treat to target approach. The essential basic measures include life-long hydroxychloroquine as well as protection from sunlight (UV) and vitamin D substitution...

INTRODUCTION: Vitiligo is a common acquired pigmentary skin disorder. Vitamin D is responsible for skin pigmentation, increases tyrosinase activity and melanogenesis, and exhibits immunoregulatory functions. Low levels of vitamin D are associated with many autoimmune diseases, including systemic lupus, diabetes mellitus, rheumatoid arthritis, multiple sclerosis and alopecia areata. Few reports have evaluated serum vitamin D levels in vitiligo patients, and their results are conflicting...

OBJECTIVE: Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease. However, the exact mechanism underlying SLE-related osteopenia and osteoporosis in patients newly diagnosed with SLE remains unknown. METHODS: 60 male subjects with SLE aged 20-30 years were enrolled. Serum osteocalcin was examined as a marker of bone formation and type I collagen degradation products (β-crosslaps) as markers of bone resorption. Lumbar spine (L1-L4) and total hip bone mineral density (BMD) were determined by dual energy X-ray absorption (DXA)...

Vitamin D should not be considered only as a vitamin. It has a relevant role in many functions of body regulation, both skeletal and extra skeletal and this makes vitamin D an essential element for a healthy status. This is well explained by a ubiquitous presence of vitamin D receptors. Nowadays extra skeletal effects have a more interesting impact in medical practice. The paracrine and autocrine action of vitamin D has a pivotal role for these effects. The activation of the cellular transcriptional process leads to the expression of beta-defensin and cathelicidin, activating the Th1 pathway, related to innate immunity against bacteria...

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with multi-organ inflammation, linked to loss of immune tolerance to self-antigens and the production of a diversity of autoantibodies, with a negative impact on the patients' quality of life. Regulatory T cells have been reported as deficient in number and function in SLE patients. However, some authors also described an enrichment of this cell type. The hypothesis that certain forms of autoimmunity may result from a conversion of Treg cells into a Th17 cell phenotype has been suggested by some studies...

Objective Patients with Systemic Lupus Erythematosus (SLE) have an increased risk of cardiovascular disease (CVD) and impaired endothelial repair. Although vitamin D deficiency is associated with increased CVD risk in the general population, a causal relationship has not been demonstrated. We aimed to determine whether vitamin D deficiency directly modulates endothelial dysfunction and immune responses in a murine model of SLE. Methods Vitamin D deficiency was induced in lupus-prone MRL/lpr mice by dietary restriction for 6 weeks...

PURPOSE OF REVIEW: Systemic lupus erythematosus (SLE) is the prototypic autoimmune condition, often affecting multiple organ systems, including the skin. Cutaneous lupus erythematosus (CLE) is distinct from SLE and may be skin limited or associated with systemic disease. Histopathologically, the hallmark of lupus-specific manifestations of SLE and CLE is an interface dermatitis. The cause of SLE and CLE is likely multifactorial and may include shared genetic factors. In this review, we will discuss the genetic findings related to the cutaneous manifestations of SLE and isolated CLE, with a particular focus on the lupus-specific CLE subtypes...

Systemic lupus erythematosus (SLE) is a potentially fatal autoimmune disease. Current treatment strategies rely heavily on corticosteroids, which are in turn responsible for a significant burden of morbidity, and immunosuppressives which are limited by suboptimal efficacy, increased infections and malignancies. There are significant deficiencies in our immunosuppressive armamentarium, making immunomodulatory therapies crucial, offering the opportunity to prevent disease flare and the subsequent accrual of damage...

OBJECTIVE: We examined whether measures of vitamin D were associated with transitioning to systemic lupus erythematosus (SLE) in individuals at risk for SLE. METHODS: 436 individuals who reported having a relative with SLE but who did not have SLE themselves were evaluated at baseline and again an average of 6.3 (±3.9) years later. Fifty-six individuals transitioned to SLE (≥4 cumulative American College of Rheumatology criteria). 25-Hydroxyvitamin D (25[OH]D) levels were measured by ELISA...
