The role of vitamin D in pediatric systemic lupus erythematosus - a double pawn in the immune and microbial balance. Front Immunol 2024; 15:1373904. [PMID: 38715605 PMCID: PMC11074404 DOI: 10.3389/fimmu.2024.1373904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Accepted: 04/08/2024] [Indexed: 05/23/2024] Open
Abstract
Having increased popularity during the Covid-19 pandemic, vitamin D3 is currently impressing thanks to the numerous researches aimed at its interactions with the body's homeostasis. At the same time, there is a peak in terms of recommendations for supplementation with it. Some of the studies focus on the link between autoimmune diseases and nutritional deficiencies, especially vitamin D3. Since the specialized literature aimed at children (patients between 0-18 years old) is far from equal to the informational diversity of the adult-centered branch, this review aims to bring up to date the relationship between the microbial and nutritional balance and the activity of pediatric systemic lupus erythematosus (pSLE). The desired practical purpose resides in a better understanding and an adequate, individualized management of the affected persons to reduce morbidity. The center of the summary is to establish the impact of hypovitaminosis D in the development and evolution of pediatric lupus erythematosus. We will address aspects related to the two entities of the impact played by vitamin D3 in the pathophysiological cascade of lupus, but also the risk of toxicity and its effects when the deficiency is over supplemented (hypervitaminosis D). We will debate the relationship of hypovitaminosis D with the modulation of immune function, the potentiation of inflammatory processes, the increase of oxidative stress, the perfusion of cognitive brain areas, the seasonal incidence of SLE and its severity. Finally, we review current knowledge, post-pandemic, regarding the hypovitaminosis D - pSLE relationship.

Abstract
PURPOSE This meta-analysis aimed to explore correlations between vitamin D and idiopathic inflammatory myopathy (IIM). METHODS A comprehensive database search was conducted on 13 October 2020. Mean differences (MDs) and aggregated risk ratios (RR) with 95% confidence intervals (CIs) were used to determine the correlation between vitamin D deficiency (VDD) and IIM. Statistical analysis was performed with RevMan 5.4 and Stata15, statistical significance was set at p < 0.05. RESULTS Search revealed five studies with 286 IIM patients and 480 healthy controls. Results with random-effects modeling indicated that serum vitamin D levels were significantly lower in IIM patients than in healthy controls (MD = -13.10 ng/mL; 95% CI: -16.51 to -9.68; p < 0.00001). No differences were found between patients with IIM and other autoimmune diseases on vitamin D levels (MD =-2.65 ng/mL; 95% CI: -11.31-6.01; p = 0.55). In two studies with 185 IIM patients, those with low vitamin D levels exhibited higher creatine kinase levels (MD = 85.20 IU/L; 95% CI: 72.67-97.73; p < 0.00001) than those with normal vitamin D levels. VDD was correlated with an increased risk of IIM (RR = 3.24, 95% CI: 1.81-5.79; p < 0.0001). CONCLUSION This meta-analysis showed correlations between vitamin D level and IIM. The results indicated, VDD may be a risk factor for IIM, a determinant of immune dysregulation in IIM, or a consequence of IIM. Also, it implied further research to determine whether vitamin D supplementation is beneficial for patients with IIM.

Abstract
BACKGROUND Seasonal variation and sunlight exposure can impact serum vitamin D levels, potentially influencing lupus symptoms. We investigated seasonal vitamin D levels and their correlation with clinical manifestations and disease activity in systemic lupus erythematosus (SLE). METHODS Serum 25(OH) vitamin D3 (25(OH)D3) levels were categorised as deficient (25(OH)D3 < 10 ng/mL), insufficient (10-30 ng/mL) and sufficiency (>30 ng/mL) in participants analysed in winter (n = 407) and summer (n = 377). Logistic regression analysis was performed to assess the impact of vitamin D levels on achieving a lupus low disease activity state (LLDAS), stratified by season. RESULTS The mean serum 25(OH)D3 levels differed significantly between the winter and summer measurement groups (22.4 vs. 24.2 ng/mL; p = .018). The prevalences of vitamin D deficiency, insufficiency and sufficiency in the winter group were 12.8%, 66.6% and 20.6%, respectively, compared with 4.5%, 67.9% and 27.6% in the summer group. Achieving LLDAS was highest in the vitamin D sufficiency group (winter: 56.6%, summer: 55%) and lowest in the vitamin D deficiency group (winter: 15.4%, summer: 13.6%), with significant differences (all p < .001). Multivariate analysis identified SLE disease activity index ≤4, normal anti-double-stranded DNA and vitamin D sufficiency as significant factors for achieving LLDAS in both seasons. CONCLUSIONS Sufficient vitamin D levels are important for achieving LLDAS in patients with SLE during winter and summer. Therefore, physicians should pay attention to the adequacy of vitamin D levels and consider recommending vitamin D supplementation for patients with vitamin D insufficiency.

Abstract
There is a paucity of studies assessing multidisciplinary interventions focused on tackling physical inactivity/sedentary behavior and poor dietary habits in SLE. The Living well with Lupus (LWWL) is a randomized controlled trial to investigate whether a six-month lifestyle change intervention will improve cardiometabolic risk factors (primary outcome) among systemic lupus erythematosus (SLE) patients with low disease activity (SLEDAI score ≤ 4) and with high cardiovascular risk. As secondary goals, we will evaluate: (1) the intervention's safety, efficacy, and feasibility in promoting lifestyle changes, and (2) the effects of the intervention on secondary outcomes (i.e., clinical parameters, functional capacity, fatigue, psychological aspects, sleep quality and health-related quality of life). Patients will be randomly allocated to either a control (i.e., standard care) or a lifestyle intervention group using a simple randomization (1:1 ratio, blocks of 20). Mixed Model analyses will be conducted for comparing groups following an intention-to-treat approach. A per protocol analysis will also be conducted. This study has the potential to generate new, clinically relevant data able to refine the multidisciplinary management of SLE patients. Protocol version number: NCT04431167 (first version).

Abstract
Vitamin D is a steroid hormone with potent immune-modulating properties. It has been shown to stimulate innate immunity and induce immune tolerance. Extensive research efforts have shown that vitamin D deficiency may be related to the development of autoimmune diseases. Vitamin D deficiency has been observed in patients with rheumatoid arthritis (RA) and has been shown to be inversely related to disease activity. Moreover, vitamin D deficiency may be implicated in the pathogenesis of the disease. Vitamin D deficiency has also been observed in patients with systemic lupus erythematosus (SLE). It has been found to be inversely related to disease activity and renal involvement. In addition, vitamin D receptor polymorphisms have been studied in SLE. Vitamin D levels have been studied in patients with Sjogren's syndrome, and vitamin D deficiency may be related to neuropathy and the development of lymphoma in the context of Sjogren's syndrome. Vitamin D deficiency has been observed in ankylosing spondylitis, psoriatic arthritis (PsA), and idiopathic inflammatory myopathies. Vitamin D deficiency has also been observed in systemic sclerosis. Vitamin D deficiency may be implicated in the pathogenesis of autoimmunity, and it may be administered to prevent autoimmune disease and reduce pain in the context of autoimmune rheumatic disorders.

Abstract
Systemic lupus erythematosus (SLE) is a devastating autoimmune disease that can result in substantial morbidity and mortality. Diagnosis and treatment of SLE are clinical challenges. Patient presentation and response to therapy are heterogeneous because of the complex immune dysregulation that results in SLE disease pathogenesis. An intricate interplay between genetic risk and skewing of adaptive and innate immune system responses leads to overproduction of type I interferons and other cytokines, complement activation, immune-complex deposition, and ultimately inflammation and tissue damage. Here, we review the classification criteria as well as standard and emerging diagnostic tools available to identify patients with SLE. We then focus on medical management, including novel therapeutics, nonpharmacologic interventions, and comorbidity management.

Abstract
INTRODUCTION In this study, it was aimed to compare the effects of both melatonin and 25-hydroxyvitamin D3, defined as an immune modulator, on laboratory diagnostic criteria parameters and disease activity in patients with systemic lupus erythematosus (SLE). METHODS The study included 56 women with SLE and 40 healthy women (control group). Melatonin and 25-hydroxyvitamin D3 levels of patients and healthy individuals included in the study were examined. In addition, leukocytes, lymphocytes, platelets, C3, C4, anti-double-stranded DNA (Anti-dsDNA), antinuclear antibody, and SLE disease activity index (SLEDAI) were analyzed in women with SLE. Patients were divided into four subgroups according to SLEDAI. RESULTS Melatonin and 25-hydroxyvitamin D3 levels of women with SLE were lower than healthy women (p < 0.001). Both melatonin and 25-hydroxyvitamin D3 levels were not correlated with laboratory diagnostic criteria parameters. Only 25-hydroxyvitamin D3 levels were correlated with leukocyte levels (p < 0.01). There was no significant difference between the melatonin levels of the subgroups. The 25-hydroxyvitamin D3 levels of the subgroup without disease activity were higher than levels of the subgroups with disease activity (p < 0.05). There was a negative correlation between SLEDAI score and 25-hydroxyvitamin D3 levels (p < 0.05). CONCLUSION Women with SLE had lower melatonin and 25-hydroxyvitamin D3 levels than healthy women. On the other hand, parameters of laboratory diagnostic criteria of SLE disease were not related. Only 25-hydroxyvitamin D3 levels were inversely related leukocyte levels. SLE disease activity was not correlated with melatonin levels but negatively correlated with 25-hydroxyvitamin D3 levels. Key Points • Women with SLE have low levels of melatonin and 25-hydroxyvitamin D3. • Melatonin and 25-hydroxyvitamin D3 levels are not related to the laboratory diagnostic criteria parameters for SLE disease. • Low levels of melatonin and 25-hydroxyvitamin D3 may be a factor in the unbalanced immune system of SLE. • Supplementation of melatonin and 25-hydroxyvitamin D3 may be recommended for women patients with SLE.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease characterised by immune dysregulation affecting multiple organs. Current anti-inflammatory treatments used in SLE are associated with unwanted side-effects. Dietary supplementation has been suggested as a safe and effective addition to conventional treatment, but evidence of efficacy in SLE or preventing associated comorbidities is uncertain. METHODS We identified literature on clinical trials focused on nutritional interventions in SLE aiming to improve inflammation and comorbidities. A systematic-type search on Embase, Medline, and the Cochrane Library, was conducted to identify nutritional interventions among SLE patients in the past 15 years that met our inclusion criteria. RESULTS We identified 2754 articles, of which 14 were eligible for inclusion based on our set criteria and were subsequently quality assessed. Vitamin D or E supplementation was associated with respective improvement of inflammatory markers or antibody production, but not disease activity scores in most studies. Despite their expected synergistic actions, the addition of curcumin on vitamin D supplementation had no additional effects on disease activity or inflammatory markers. Trials of omega-3 fatty acid supplementation presented significant reductions in ESR, CRP, disease activity, inflammatory markers, and oxidative stress, and improved lipid levels and endothelial function, while a low glycaemic index (GI) diet showed evidence of reduced weight and improved fatigue in patients. CONCLUSIONS Different dietary guidelines can therefore be implicated to target specific SLE symptoms or therapeutic side-effects. This systematic review highlights the scarcity of larger and longer in duration trials with homogenous methodologies and verifiable outcomes to assess disease progression.

Abstract
Vitamin D (VD) plays an important role in infectious and autoimmune diseases. We investigated the association between serum VD levels and active human cytomegalovirus (HCMV) infections in pediatric systemic lupus erythematosus (SLE) patients. From January 2015 to June 2021, one hundred and twenty children diagnosed with SLE and 100 healthy children were enrolled. Using ELISA, serum 25(OH)D levels were detected. Serum anti-HCMV IgM antibodies were measured by a chemiluminescence immunoassay. Comparisons of 25(OH)D levels between SLE patients and healthy children were performed, as well as subgroups of SLE patients with or without active HCMV infections. Serum 25(OH)D levels of SLE patients were significantly lower than those of healthy children (35.3 ± 12.9 vs 49.3 ± 15.3, P < 0.001). VD deficiency ratio was higher in SLE patients (89.2%) than that in healthy children (52.0%). Serum 25(OH)D levels in the positive anti-HCMV IgM group were significantly lower than those of the negative anti-HCMV IgM group (30.6 ± 12.3 vs 38.2 ± 12.5, P < 0.001). The severe VD deficiency ratio was significantly higher in HCMV-IgM(+)-SLE patients (42.2%) than that in HCMV-IgM(-)-SLE patients (13.3%). This study suggested that serum VD level is associated with active HCMV infections in pediatric SLE patients.

Abstract
This study aims to assess the role of vitamin D on systemic lupus erythematosus (SLE) patients and its effects on systemic lupus erythematosus disease activity index (SLEDAI), anti-double-stranded DNA (anti-dsDNA), C3, C4, and fatigue in patients with SLE. A systemic search was conducted using three electronic databases, i.e., PubMed/Medline, Cochrane Library, and Google Scholar. Review Manager 5.4.1 (The Cochrane Collaboration, The Nordic Cochrane Centre, Copenhagen, Denmark) was employed for statistical analysis. All studies meeting the inclusion criteria were selected. A random-effect model was used to pool the studies, and the result was reported in the standard mean difference (SMD) with its corresponding 95% confidence interval. Six randomized controlled trials were selected. Five outcomes were assessed (SLEDAI, anti-dsDNA, C3, C4, and fatigue) to evaluate the role of vitamin D in SLE patients. A significant decrease in SLEDAI (SMD = -0.85 (-1.12, -0.58); p < 0.00001; I2 = 42%) and a non-significant decrease in anti-dsDNA (SMD = -0.09 (-0.03, 0.12); p = 0.42; I2 = 0%) was noted. A significant increase in levels of C3 (SMD = 0.30 (0.09, 0.51); p = 0.006; I2 = 0%) and fatigue (SMD = -1.27 (-2.38, -0.16); p = 0.02; I2 = 56%) was noted when vitamin D was used. Insignificant difference was observed in C4 (SMD = 0.20 (-0.02, 0.41); p = 0.07; I2 = 0%). Vitamin D in SLE patients showed a significant decrease in SLEDAI scores and a significant increase in C3 levels. The effect of vitamin D on fatigue was inconclusive. No significant difference in anti-dsDNA and C4 levels was noted.

Abstract
BACKGROUND & AIMS The latitudinal gradient effect is described for several autoimmune diseases including celiac disease in the United States. However, the association between latitude and global celiac disease prevalence is unknown. We aimed to explore the association between latitude and serology-based celiac disease prevalence through meta-analysis. METHODS We searched MEDLINE, Embase, Cochrane, and Scopus databases from their beginning through June 29, 2018, to identify screening studies that targeted a general population sample, used serology-based screening tests, and provided a clear location from which we could assign a latitude. Studies were excluded if sampling was based on symptoms, risk factors, or referral. Study selection and data extraction were performed by independent reviewers. The association measures between latitude and prevalence of serology-based celiac disease were evaluated with random-effects meta-analyses and meta-regression. RESULTS Of the identified 4667 unique citations, 128 studies were included, with 155 prevalence estimates representing 40 countries. Celiac disease was more prevalent at the higher latitudes of 51° to 60° (relative risk [RR], 1.62; 95% CI, 1.09-2.38) and 61° to 70° (RR, 2.30; 95% CI, 1.36-3.89) compared with the 41° to 50° reference level. No statistically significant difference was observed at lower latitudes. When latitude was treated as continuous, we found a statistically significant association between CD prevalence and latitude overall in the world (RR, 1.03, 95% CI, 1.01-1.05) and a subregional analysis of Europe (RR, 1.05; 95% CI, 1.02-1.07) and North America (RR, 1.1; 95% CI, 1.0-1.2). CONCLUSIONS In this comprehensive review of screening studies, we found that a higher latitude was associated with greater serology-based celiac disease prevalence.

An evaluation of sleep habits and childhood-onset systemic lupus erythematosus. Clin Rheumatol 2022; 41:2831-2837. [PMID: 35639260 DOI: 10.1007/s10067-022-06225-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2021] [Revised: 05/20/2022] [Accepted: 05/23/2022] [Indexed: 11/03/2022]
Abstract
OBJECTIVES Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease, known for its heterogeneous clinical presentation. Although it is rarer in children, a more severe clinical course can be seen than in adults. It is known that sleep has physiological and developmental importance in children, and there are many studies on sleep quality in adult SLE patients. The aims of this study are to evaluate the sleep habits of children and adolescents with SLE and to compare them with their healthy peers. METHODS The study included 48 children and adolescents with SLE and 64 healthy peers as a control group. The Children's Sleep Habits Questionnaire was used to evaluate the sleep characteristics of children. RESULTS The age and gender of the children were similar across groups. The bedtime resistance and night waking scores of SLE patients were significantly higher than those of the control group. Total sleep score was higher in patients with SLE than in the control group, but there was no significant difference (47.13±7.63 vs 44.61±8.17; p=0.051). Similarly, the rate of sleep disorders in the patient group (75%) was higher than that of the control group (61%), though the differences were not statistically significant (p = 0.156). There was no correlation between disease severity and sleep problems. CONCLUSION This research demonstrated that sleep disorders tend to increase in children and adolescents with SLE. Therefore, clinicians should pay attention to sleep disorders during the follow-up sessions of children and adolescents with SLE. Key Points • Sleep disorders tend to increase in children and adolescents with SLE. • Disease severity is not associated with sleep problems.

Abstract
Background: This study was designed to evaluate the influence of vitamin D receptor (VDR) gene polymorphisms on systemic lupus erythematosus (SLE) susceptibility. Methods: All eligible investigations were identified, the number of the various genotypes in the case and control groups were reviewed. A pooled analysis was performed using the Stata software. The study was carried out according to the Ethics Review Committee of The Third Xiangya Hospital, Central South University. Results: This meta-analysis included 19 studies. In our analysis, the VDR Apal polymorphism was correlated with SLE susceptibility in the overall population (AA vs. aa: odds ratio [OR] = 1.374, 95% confidence interval [CI]: 1.115-1.692, p = 0.003; AA + Aa vs. aa: OR = 1.342, 95% CI: 1.139-1.583, p < 0.01). The VDR Bsml and Apal polymorphisms were correlated with SLE susceptibility in Caucasian subjects (BB vs. Bb + bb: OR = 0.734, 95% CI: 0.593-0.909, p = 0.005; B vs. b: OR = 0.865, 95% CI: 0.760-0.983, p = 0.026; AA vs. aa: OR = 1.329, 95% CI: 1.016-1.740, p = 0.038). The VDR BsmI and FokI polymorphisms were correlated with SLE in African subjects (B vs. b: OR = 1.898, 95% CI: 1.458-2.470, p<0.01; BB + Bb vs. bb: OR = 2.935, 95% CI: 1.944-4.430, p < 0.01; FF vs. Ff + ff: OR = 2.424, 95% CI: 1.673-3.512, p < 0.01; F vs. f: OR = 1.720, 95% CI: 1.417-2.087, p < 0.01; FF vs. ff: OR = 3.154, 95% CI: 2.083-4.774, p < 0.01; FF + Ff vs. ff: OR = 1.803, 95% CI: 1.363-2.384, p < 0.01). In addition, the VDR Apal polymorphism was correlated with SLE in female subjects (AA vs. aa: OR = 1.392, 95% CI: 1.049-1.849, p = 0.022) when stratified by gender. But there was no association between the VDR TaqI polymorphism and SLE susceptibility in our analysis. Conclusions: The VDR Apal polymorphism was associated with SLE susceptibility in general populations; in addition, Apal polymorphism was associated with SLE in female subjects. The VDR Bsml gene polymorphism was correlated with SLE susceptibility in Caucasian and African populations, whereas the VDR FokI polymorphism was correlated with SLE in African populations. But there was no association between the VDR TaqI polymorphism and SLE susceptibility in our analysis.

Abstract
OBJECTIVE To investigate the application value of serum 25-hydroxy vitamin D [25(OH)D] in systemic lupus erythematosus (SLE). METHODS Data of 158 patients with SLE in Department of Rheumatology and Immunology in the People's Hospital of Xinjiang Uygur Autonomous Region from July 2016 to July 2019. All the SLE patients were divided into two groups by SLE scores of the disease activity index (SLEADI): 59 cases of active group (SLEADI > 4), 99 cases of non-active group (SLEDAI ≤4). Fifty healthy people were selected as healthy control group. The patients' general information and their laboratory data including serum 25(OH)D levels were collected. Statistical methods used were t-test, Spearman's correalation analysis and Logistic regression analysis. RESULTS (1) A total of 208 cases were included in this study. The level of 25(OH)D in SLE group [10.4(5.6, 15.8) μg/L] was significantly lower than that in healthy control group [25.5(22.8, 32.3) μg/L, P < 0.01]. 25(OH)D level in active SLE patients [6.2(3.7, 13.8) μg/L] was significantly lower than that in remission SLE patients [12.3(7.2, 16.7) μg/L, P < 0.01]. The serum 25(OH)D level in lupus nephritis [6.7 (4.4, 12.9) μg/L] was significantly lower than that in SLE without renal involvement [13.3 (7.4, 18.7) μg/L, P < 0.01]. (2) A significant negative correlation was demonstrated between the serum level of 25(OH)D and SLEDAI (r=-0.35, P < 0.01), and the 24h urinary protein excretion (r=-0.39, P < 0.01).Positive correlation was demonstrated between the serum level of 25(OH)D and C3 that decreased (r=0.249, P < 0.05). (3) Univariate analysis showed anti- dsDNA antibodies(ds-DNA), anti-Sm antibodies(Sm), IgG, C3, C4, erythrocyte sedimentation rate (ESR), 24h urinary protein quantification(24h-pro) and 25(OH)D were associated with disease activity in the SLE patients; Multivariate Logistic regression analysis showed that 25(OH)D was associated with the disease activity of the lupus patients. CONCLUSION The decrease of vitamin D level is related to the disease activity of SLE patients, and may be related to lupus nephritis, which plays an important role in the occurrence and development of SLE.

Abstract
The aim of this study is to identify rheumatology practice care gaps in evaluating for vitamin D deficiency in systemic lupus erythematosus (SLE), as well as adherence to vitamin D replacement in SLE patients currently on corticosteroid therapy. Data for this study were collected from the Southern California Lupus Registry in addition to data extraction from medical health records. Evaluation of serum vitamin D level within 6 months of patient encounter, current or prior use of systemic corticosteroids, and vitamin D replacement in patients receiving corticosteroid therapy were noted. Vitamin D deficiency was defined as serum 25(OH)D3 less than 30 ng/ml. Of 182 patients in the cohort, data were available for 176. Evaluation of vitamin D deficiency was noted in 49 patients (28%), 27 (55%) of whom had abnormal values. Current corticosteroid use was noted in 56 (32%) patients and prior use in 73 (41%). Vitamin D replacement was prescribed to 30 (54%) patients with current corticosteroid use. In an academic rheumatology clinic, we have identified underevaluation for vitamin D deficiency in SLE patients despite increasing awareness of its contribution to disease activity. Further, routine supplementation of vitamin D is particularly lacking in individuals receiving systemic corticosteroids. This presents a practical opportunity for improvement in SLE clinical care.

Abstract
OBJECTIVES SLE is a chronic autoimmune disease, which can affect the level of bone metabolism and increase the risk of osteoporosis and fracture. The purpose of this research is to study the effect of SLE on bone turnover markers without the influence of glucocorticoids. METHODS A total of 865 female subjects were recruited from Zhejiang Provincial People's Hospital and the First Hospital of Jiaxing, including 391 SLE patients without the influence of glucocorticoids and 474 non-SLE people. We detected Bone turnover markers including amino-terminal propeptide of type 1 procollagen (P1NP), C-terminal turnover of β - I collagen (β-CTX), N-terminal midfragment of osteocalcin (NMID) and 25(OH)D, and analyzed the difference in Bone turnover markers between the SLE group and the control group, as well as the influence of age and season on bone metabolism in female SLE patients. RESULTS In the SLE group, the average age was 43.93±13.95 years old. In the control group, the average age was 44.84±11.42 years old. There was no difference between the two groups (t = 1.03, P = 0.30). P1NP, NMID and 25(OH)D in the SLE group were significantly lower than those in the control group (Z = 8.44, p < 0.001; Z = 14.41, p < 0.001; Z = 2.19, p = 0.029), and β-CTX in the SLE group was significantly higher than that in the control group (Z = 2.61, p = 0.009). In addition, the levers of β-CTX, NMID, P1NP and 25(OH)D in older SLE female patients were statistically significantly higher than those in younger (ρ = 0.104, p = 0.041; ρ = 0.223, p < 0.001; ρ = 0.105, p = 0.038; ρ = 0.289, p < 0.001). Moreover, β-CTX reached a high value in summer and PINP reached a low value in winter. CONCLUSION The bone formation markers of female SLE patients without glucocorticoid were lower than those of normal people and the bone resorption marker was higher than that of normal people. The 25 (OH) D of female SLE patients without glucocorticoid was lower than that of normal people. The risk of osteoporosis and fracture may be higher in elderly women with SLE. The bone resorption level of female SLE patients is high in summer and the bone formation level is low in winter.

Abstract
BACKGROUND/AIMS Despite recent improvements in the quality of life of patients with systemic lupus erythematosus (SLE), osteoporosis, and osteoporotic fractures are one of the major complications of SLE. Furthermore, limited data are available on the incidence and predictor of osteoporotic fractures in Korean patients with SLE. Herein, we aimed to assess the incidence and risk factors for osteoporotic fractures in Korean SLE patients compared to those without SLE. METHODS SLE patients aged ≥ 40 years (n = 10,434; mean age, 51.3 ± 9.1 years; women, 89.7%) were selected from the Korean National Health Insurance Service database, spanning a period from 2008 to 2014. Age- and sex-matched controls (n = 52,170) were randomly sampled in a 5:1 ratio from non-SLE individuals. The primary outcome was the first occurrence of osteoporotic fracture. RESULTS The incidence of osteoporotic fractures was significantly higher in the SLE patients (19.085 per 1,000 person-years) than in matched controls (6.530 per 1,000 person-years). According to the multivariable Cox proportional analysis, patients with SLE exhibited a higher osteoporotic fracture rate than the control group (hazards ratio, 2.964; 95% confidence interval, 2.754 to 3.188), even after adjustment for confounding variables. In the subgroup analysis, male SLE patients or SLE patients aged 40 to 65 years were associated with a higher osteoporotic fracture rate than women SLE patients or SLE patients aged ≥ 65 years, respectively. CONCLUSION We found a 2.964-fold increased risk of osteoporotic fracture in SLE patients compared to age- and sex-matched non-SLE controls. Male or middle-aged SLE patients had a relatively higher fracture risk among patients with SLE.

Abstract
Objectives
This study aims to determine the prevalence of vitamin D deficiency in Pakistani systemic lupus erythematosus (SLE) patients and the effect of vitamin D deficiency on the severity and outcomes of SLE. Patients and methods
This retrospective study evaluated SLE patients presenting to our hospital between January 2009 and December 2018. A total of 98 patients (13 males, 85 females; mean age 39.8±14.9 years; range, 16 to 73 years) with vitamin D levels available at the time of diagnosis were included in the study. Disease activity was measured using SLE disease activity score at the time of diagnosis and at the two-year mark. Results
Sixty-five patients were deficient in Vitamin D and out of those 46 were severely deficient. The severe disease group had more patients with vitamin D deficiency at both visits (43/78 and 33/46) while patients in remission all had normal vitamin D (12/12 and 14/14) (p≤0.001). Conclusion Vitamin D deficiency is common in SLE patients and also significantly associated with increased disease activity at the time of diagnosis and at the two-year mark. We hope this study becomes a platform for the global medical community to come together and implement early screening and monitoring of vitamin D levels and to determine the optimal level of supplementation for prevention of poor outcomes in SLE.

Abstract
Several signaling pathways are involved in the progression of kidney disease in humans and in animal models, and kidney disease is usually due to the sustained activation of these pathways. Some of the best understood pathways are specific proinflammatory cytokine and protein kinase pathways (e.g., protein kinase C and mitogen-activated kinase pathways, which cause cell proliferation and fibrosis and are associated with angiotensin II) and transforming growth factor-beta (TGF-β) signaling pathways (e.g., the TGF-β signaling pathway, which leads to increased fibrosis and kidney scarring. It is thus necessary to continue to advance our knowledge of the pathogenesis and molecular biology of kidney disease and to develop new treatments. This review provides an update of important findings about kidney diseases (including diabetic nephropathy, lupus nephritis, and vasculitis, i.e., vasculitis with antineutrophilic cytoplasmic antibodies). New disease targets, potential pathological pathways, and promising therapeutic approaches from basic science to clinical practice are presented, and the blocking of JAK/STAT and TIM-1/TIM-4 signaling pathways as potential novel therapeutic agents in lupus nephritis is discussed.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by multiple organ involvement, including the skin, joints, kidneys, lungs, central nervous system and the haematopoietic system, with a large number of complications. Despite years of study, the etiology of SLE remains unclear; thus, safe and specifically targeted therapies are lacking. In the last 20 years, researchers have explored the potential of nutritional factors on SLE and have suggested complementary treatment options through diet. This study systematically reviews and evaluates the clinical and preclinical scientific evidence of diet and dietary supplementation that either alleviate or exacerbate the symptoms of SLE. For this review, a systematic literature search was conducted using PubMed, Scopus and Google Scholar databases only for articles written in the English language. Based on the currently published literature, it was observed that a low-calorie and low-protein diet with high contents of fiber, polyunsaturated fatty acids, vitamins, minerals and polyphenols contain sufficient potential macronutrients and micronutrients to regulate the activity of the overall disease by modulating the inflammation and immune functions of SLE.

Abstract
Introduction Patients with systemic lupus erythematosus (SLE) frequently present low levels of vitamin D. However, studies that have evaluated its association with disease activity have generated contradictory results. Methods A cross-sectional study was carried out on patients diagnosed with SLE in two hospitals in Manizales, Colombia. Disease activity was evaluated by the SLE disease activity index 2000 (SLEDAI-2K) and serum concentration of 25-hydroxyvitamin D (25(OH)D) was measured by chemiluminescence. The correlation analysis was accomplished with the Spearman correlation coefficient. Results The study included 51 patients. The median SLEDAI-2K score was 8 points. The mean serum level of 25(OH)D was 24.5 ng/ml. Of the participants, 37.3% had vitamin D insufficiency and 35.3% had deficiency. An inverse correlation was found between the levels of the 25(OH)D and the SLEDAI-2K score ( r = –0.578, p < 0.001), being greater in late-onset lupus, with absence of polyautoimmunity and in patients using glucocorticoids. Conclusions Low levels of vitamin D are frequent in SLE, presenting an inverse correlation with the disease activity. This is influenced by the use of glucocorticoids, the presence of late-onset lupus and the absence of polyautoimmunity.

Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease and hypocomplementemia signifies disease activity. Several studies have shown that calcium may help maintain optimum function of immune system and metabolism in SLE. The aim of our study was to analyze the relationship between total serum calcium level and SLE activity. A total of 66 patients with SLE and 214 healthy controls were included in this study. Our results showed lower serum levels of calcium (P < .001), complement C3 (P < .001), complement C4 (P < .001), and albumin (P < .001) in patients with SLE. A negative correlation was found between serum calcium level and systemic lupus erythematosus disease activity index (SLEDAI) rating (r = -0.394, P = .001). Additionally, serum level of calcium was positively correlated with serum complement C3 level (r = 0.366, P = .003) in patients with SLE, while no such correlation was found between serum calcium level and complement C4 (r = -0.190, P = .126). Likewise, patients with SLE with normal serum calcium level showed higher complement C3 level (P < .01) than that of patients with low serum calcium level. Overall, the results displayed that patients with SLE have lower serum calcium level compared to healthy controls, and the serum calcium level is positively correlated with SLEDAI rating and serum complement C3 level in patients with SLE. In conclusion, the total serum calcium level is negatively correlated with SLE disease activity.

Abstract
OBJECTIVE AND DESIGN Recently, many studies have shown that the biologically active form of vitamin D-1,25(OH)2 D-is involved in many biological processes, including immune system modulation, and patients affected by various autoimmune diseases, such as connective tissue diseases (CTD), showed low levels of vitamin D. It is not clear if vitamin D deficiency is involved in the pathogenesis of autoimmune diseases or it is a consequence. MATERIAL We carried out a review of literature to summarize the existing connections between 25-OH vitamin D and CTD. METHODS We searched for articles on PubMed by keywords: vitamin D, connective tissue diseases, systemic lupus erythematosus, Sjogren's syndrome, systemic sclerosis, undifferentiated connective tissue disease. RESULTS The relationship between vitamin D and CTD is still not very clear, despite many studies having been performed and some data suggest a connection between these diseases and 25-OH vitamin D levels. CONCLUSIONS The limitations of the study, such as the heterogeneity of patients, methods used to measure vitamin D serum concentration and other biases, do not lead to unequivocal results to demonstrate a direct link between low vitamin D serum levels and autoimmune diseases. Further studies are needed to resolve conflicting results.

Abstract
Systemic lupus erythematosus (SLE) is a worldwide chronic autoimmune disease which may affect every organ and tissue. Genetic predisposition, environmental triggers, and the hormonal milieu, interplay in disease development and activity. Clinical manifestations and the pattern of organ involvement are widely heterogenous, reflecting the complex mosaic of disrupted molecular pathways converging into the SLE clinical phenotype. The SLE complex pathogenesis involves multiple cellular components of the innate and immune systems, presence of autoantibodies and immunocomplexes, engagement of the complement system, dysregulation of several cytokines including type I interferons, and disruption of the clearance of nucleic acids after cell death. Use of immunomodulators and immunosuppression has altered the natural course of SLE. In addition, morbidity and mortality in SLE not only derive from direct immune mediated tissue damage but also from SLE and treatment associated complications such as accelerated coronary artery disease and increased infection risk. Here, we review the diagnostic approach as well as the etiopathogenetic rationale and clinical evidence for the management of SLE. This includes 1) lifestyle changes such as avoidance of ultraviolet light; 2) prevention of comorbidities including coronary artery disease, osteoporosis, infections, and drug toxicities; 3) use of immunomodulators (i.e. hydroxychloroquine and vitamin D); and 4) immunosuppressants and targeted therapy. We also review new upcoming agents and regimens currently under study.

Abstract
Background:
Systemic Lupus Erythematosus (SLE) is a systemic autoimmune disease characterised by abnormal activation of the immune system, chronic inflammation and organ damage. Lupus patients are more prone to be vitamin D deficient. However, current evidence is not conclusive with regards to the role played by vitamin D in SLE development, progression, and clinical manifestations.
Objective:
Here, we will summarise the current knowledge about vitamin D deficiency prevalence, risk factors, molecular effects, and potential pathogenic role in SLE. We will focus on the link between vitamin D deficiency and lupus clinical manifestations, and on the clinical trials assessing the effects of vitamin D supplementation in SLE.
Method:
A detailed literature search was performed exploiting the available databases, using “vitamin D and lupus/SLE” as keywords. The relevant interventional trials published over the last decade have been considered and the results are reported here.
Conclusion:
Several immune cells express vitamin D receptors. Thus, an immunomodulatory role for vitamin D in lupus is plausible. Numerous observational studies have investigated the relationship between vitamin D levels and clinical/serological manifestations of SLE with contrasting results. Negative correlations between vitamin D levels and disease activity, fatigue, renal and cardiovascular disease, and anti-dsDNA titres have been described but not conclusively accepted. In experimental models of lupus, vitamin D supplementation can improve the disease. Interventional trials have assessed the potential therapeutic value of vitamin D in SLE, but further larger studies are needed.

Abstract
Background: Systemic lupus erythematosus is a chronic autoimmune disease that increases the risk of suboptimal vitamin D levels. Aim: To determine the effects of vitamin D and calcium supplementation on disease activity, related immune markers and bone mineral density in patients with systemic lupus erythematosus. Subjects and Methods: Eighty-one patients with systemic lupus erythematosus aged 20–70 years were recruited for this interventional study. Participants were enrolled into the following groups: no corticosteroid treatment (n = 21), corticosteroid treatment but without supplementation (n = 30) and corticosteroid treatment along with oral vitamin D and calcium supplementation (n = 30). Disease activity and laboratory parameters of all participants were measured at baseline and at 6 months. Bone mineral density was assessed using standardized dual-energy X-ray absorptiometry. Results: At baseline, none of the patients had a normal vitamin D status. There were no significant correlations between vitamin D status and the studied immune markers or disease activity values before and after supplementation. After 6 months, patients who received supplementation showed significant (P = 0.002) improvements in bone mineral density. In addition, frequency of osteopenia decreased from 40% to 16.7% and that of osteoporosis decreased from 26.7% to 13.3%. Conclusion: Vitamin D and calcium supplementation significantly improved the bone mineral density in vitamin D-deficient patients with systemic lupus erythematosus but did not significantly attenuate immune markers or disease activity. Further investigations are recommended with higher doses of vitamin D and longer durations to normalize the vitamin level and, possibly, achieve better disease control.

Abstract
Over the past two decades it has been increasingly recognized that vitamin D, aside from its crucial involvement in calcium and phosphate homeostasis and the dynamics of the musculoskeletal system, exerts its influential impact on the immune system. The mechanistic roles that vitamin D plays regarding immune activation for combating infection, as well as pathologically and mediating autoimmune conditions, have been progressively unraveled. In vitro and in vivo models have demonstrated that the action of vitamin D on various immunocytes is not unidirectional. Rather, how vitamin D affects immunocyte functions depends on the context of the immune response, in the way that its suppressive or stimulatory action offers physiologically appropriate and immunologically advantageous outcomes. In this review, the relationship between various aspects of vitamin D, starting from its adequacy in circulation to its immunological functions, as well as its autoimmune conditions, in particular systemic lupus erythematosus (SLE), a prototype autoimmune condition characterized by immune-complex mediated inflammation, will be discussed. Concurring with other groups of investigators, our group found that vitamin D deficiency is highly prevalent in patients with SLE. Furthermore, the circulating vitamin D levels appear to be correlated with a higher disease activity of SLE as well as extra-musculoskeletal complications of SLE such as fatigue, cardiovascular risk, and cognitive impairment.

Abstract
The aim of this study is to evaluate the relationship between baseline serum 25-hydroxyvitamin D3 levels and SLE activity/flares over time. This is a longitudinal study of 276 patients who fulfilled ≥ 4 ACR criteria for SLE and recruited in the year 2011. Serum samples were collected at baseline and assayed for 25-hydroxyvitamin D3 at the end of a mean follow-up of 32.5 months. Participants were stratified into three groups according to baseline 25-hydroxyvitamin D3 levels: group I (< 15 ng/ml, deficiency), group II (15-30 ng/ml, insufficiency), and group III (> 30 ng/ml, adequate). Baseline and summated SLE disease activity index (SLEDAI) score over time and the annual incidence of lupus flares were compared among these groups. 25-hydroxyvitamin D3 levels of < 15, 15-30, and > 30 ng/ml were present in 26, 54, and 20% of the recruited patients, respectively. Group I had significantly higher baseline SLEDAI scores. After a follow-up of 32.5 ± 5.5 months, 153 mild/moderate and 91 severe flares developed. The mean summated SLEDAI was 3.2 ± 2.0 in group I, 2.4 ± 1.9 in group II and 2.7 ± 2.1 in group III patients (P = 0.02). The annual incidence of mild/moderate and severe flares was 0.26 ± 0.39 and 0.20 ± 0.45 (group I); 0.20 ± 0.33 and 0.09 ± 0.22 (group II); and 0.20 ± 0.32 and 0.14 ± 0.46 (group III), respectively (P > 0.05). In a subgroup of 73 patients who were clinically and serologically quiescent at baseline, a similar trend of more flares was observed in group I patients. Vitamin D deficiency was frequent in Chinese SLE patients and was associated with more active disease at baseline and over time, as well as a trend of more severe lupus flares.

Abstract
Osteoporosis is a systemic skeletal disorder characterized by a decrease in bone mass and microarchitectural deterioration of bone tissue. The World Health Organization has defined osteoporosis as a decrease in bone mass (50%) and bony quality (50%). Vitamin D, a steroid hormone, is crucial for skeletal health and in mineral metabolism. Its direct action on osteoblasts and osteoclasts and interaction with nonskeletal tissues help in maintaining a balance between bone turnover and bone growth. Vitamin D affects the activity of osteoblasts, osteoclasts, and osteocytes, suggesting that it affects bone formation, bone resorption, and bone quality. At physiological concentrations, active vitamin D maintains a normal rate of bone resorption and formation through the RANKL/OPG signal. However, active vitamin D at pharmacological concentration inhibits bone resorption at a higher rate than that of bone formation, which influences the bone quality and quantity. Nutritional vitamin D rather than active vitamin D activates osteoblasts and maintains serum 25(OH)D3 concentration. Despite many unanswered questions, much data support nutritional vitamin D use in osteoporosis patients. This article emphasizes the role of nutritional vitamin D replacement in different turnover status (high or low bone turnover disorders) of osteoporosis together with either anti-resorptive (Bisphosphonate, Denosumab et.) or anabolic (Teriparatide) agents when osteoporosis persists.

Abstract
Objective: The aim of this study was to evaluate the scientific evidence of dietary intervention, either through diet or supplementation, and its effects on the health of patients with systemic lupus erythematosus. Methods: Literature searches were conducted using Scopus, PubMed, BioMed Central and Science Direct databases. The terms used for the search were diet, nutritional support, nutrition therapy and systemic lupus erythematosus. Results: Eleven studies with interventions related to supplementation of omega-3 fatty acids, vitamin D and turmeric, as well as changes in diet composition, such as low glycaemic index diet were identified. Conclusions: The studies evidenced that omega-3 supplementation reduced inflammation, disease activity, endothelial dysfunction and oxidative stress; vitamin D supplementation increased serum levels, reduced inflammatory and hemostatic markers; turmeric supplementation reduced proteinuria, hematuria and systolic blood pressure; and low glycaemic index diet caused weight loss and reduced fatigue.

Abstract
Vitamin D is one of the main groups of sterols; playing an important role in phospho-calcic metabolism. The conversion of 7-dehydrocholesterol to pre- vitamin D3 in the skin, through solar ultraviolet B radiation, is the main source of vitamin D. Since lupus patients are usually photosensitive, the risk of developing vitamin D deficiency in is high in this population. Although evidences showed the connotation between systemic lupus erythematosus (SLE) and vitamin D through which SLE can lead to lower vitamin D levels, it is also important to consider the possibility that vitamin D deficiency may have a causative role in SLE etiology. This paper analyzes existing data from various studies to highlight the role of vitamin D deficiency in SLE occurrence and aggravation and the probable efficacy of vitamin D supplementation on SLE patients. We searched “Science Direct” and “Pub Med” using “Vitamin D” and “SLE” for finding the studies focusing on the association between vitamin D deficiency and SLE incidence and consequences. Evidences show that vitamin D plays an important role in the pathogenesis and progression of SLE and vitamin D supplementation seems to ameliorate inflammatory and hemostatic markers; so, can improve clinical subsequent.

Abstract
Background Patients with systemic lupus erythematosus (SLE) are prone to develop vitamin D (25(OH) D3) deficiency, due to several factors and there is an association between lower vitamin D levels and higher SLE disease activity. The aim of this research was to assess the prevalence of vitamin D deficiency in Egyptian female patients with SLE. Furthermore, we analyzed the potential relationship between this deficiency and SLE manifestations, disease activity, and its effect on interferon alpha (IFN-α) gene expression and serum level. Methods We evaluated the serum levels of vitamin D 25(OH)D3 and IFN-α by enzyme-linked immunosorbent assay (ELISA). IFN-α gene expression was measured by real-time polymerase chain reaction (PCR) assay in 123 Egyptian female patients with SLE and in 100 females as a healthy control group. Results Vitamin D deficiency was prevalent in 20.30%, while insufficiency was prevalent in 42.40% of the total group of patients. Serum levels of 25(OH)D3 were significantly decreased in the group of severe disease, and in the group of patients with lupus nephritis. 25(OH)D3 showed highly significant negative correlation with the SLE Disease Activity Index (SLEDAI) in the high activity group and lupus nephritis group. There was a significant negative correlation between 25(OH)D3 and IFN-α serum level and gene expression in all patients; more significant in the group with lupus nephritis. Conclusions The deficiency of 25(OH)D3 has a direct relationship with increase disease activity and nephritis in Egyptian SLE patients, suggesting the need for vitamin D supplementation in these patients. Also, it is directly correlated with increased secretion and gene expression of IFN-α, suggesting its role in pathogenesis of lupus nephritis, to be confirmed by further longitudinal observational studies.

The association between vitamin D receptor polymorphisms and serum 25-hydroxyvitamin D levels with ulcerative colitis in Chinese Han population. Clin Res Hepatol Gastroenterol 2017; 41:110-117. [PMID: 27771345 DOI: 10.1016/j.clinre.2016.09.001] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2016] [Revised: 08/18/2016] [Accepted: 09/02/2016] [Indexed: 02/04/2023]
Abstract
There is now growing evidence suggesting that Vitamin D is playing a critical role in modulating the innate and adaptive immune responses. Several polymorphisms have been identified in the vitamin D receptor (VDR) gene but their association with ulcerative colitis (UC) susceptibility remained controversy. In the current study, we examined the association between VDR polymorphisms and serum level of 25-hydroxyvitamin D [25(OH)D] with UC in Chinese Han population. Polymorphisms of FokI (rs2228570)/BsmI (rs1544410)/ApaI (rs7975232)/TaqI (rs731236) in the VDR gene were assessed in a case-control study comprising 404 UC patients and 612 controls. Moreover, 25(OH)D levels were measured by electro-chemiluminescence immunoassay in 75 UC patients and 120 controls. Our results suggested that BsmI polymorphism frequency was significantly lower in UC patients (P=0.028), and the frequency of AAC haplotype formed by BsmI, ApaI and TaqI was also significantly lower in UC patients (P=0.012). Moreover, FokI polymorphism was more frequently observed in patients with mild and moderate UC as compared to those with severe UC (P=0.001, P<0.001, respectively). Average 25(OH)D level was lower in UC patients than in controls (19.3±6.8 vs. 21.8±7.3ng/mL, P=0.017), and was significantly correlated with hemoglobin (β=0.49, P<0.001), C-reactive protein (β=-0.36, P<0.001), severity of UC (β=-0.21, P=0.025) and FokI polymorphism (β=-0.20, P=0.031) in UC patients. Interestingly, there was a significant correlation between FokI polymorphism and vitamin D deficiency (<20ng/mL) in UC patients (P=0.006). Together, these results supported that VDR polymorphisms and 25(OH)D level were significantly correlated with UC risk and severity in Chinese Han population.

Abstract
BACKGROUND Cutaneous lupus erythematosus (CLE) is an autoimmune disease, often exacerbated by sun exposure. Patients are encouraged to avoid sun exposure, therefore predisposing them to vitamin D deficiency. AIM To investigate the prevalence of and risk factors for vitamin D deficiency in patients with CLE. METHODS Total serum 25-hydroxy vitamin D (25(OH)D) was measured in 87 consecutive patients with CLE and in 79 controls. Clinical characteristics, disease severity, medications used and lifestyle factors were analysed and compared to determine risk factors for inadequate (25(OH)D), defined as a serum (25(OH)D) level of < 20 μg/L. RESULTS We found that 51% (n = 44) of the patients with CLE had 25(OH)D levels of < 20 μg/L compared with 73% (n = 58) of the controls (P < 0.01). No significant differences in (25(OH)D) levels were found between cases and controls with regard to age, sex, ethnicity, smoking, sun exposure, sunblock use or vitamin D supplementation. Treatment with antimalarials showed a statistically significant association with lower vitamin D levels. CONCLUSION Low levels of vitamin D were found in both patients with CLE and controls. Despite being on vitamin D supplementation and living in an equatorial location, our Asian patients with CLE still had low levels of vitamin D. It is therefore important to ensure adequate vitamin D supplementation in patients with CLE, especially for those who are on antimalarial therapy.

Abstract
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. Currently available immunomodulators include prasterone (synthetic dehydroeipandrosterone), vitamin D, hydroxychloroquine and belimumab. These therapies, acting via numerous cellular and cytokine pathways, have been shown to modify the aberrant immune responses associated with SLE without overt immunosuppression. Vitamin D is important in SLE and supplementation appears to have a positive impact on disease activity particularly proteinuria. Belimumab has specific immunomodulatory properties and is an effective therapy in those with specific serological and clinical characteristics predictive of response. Hydroxychloroquine is a crucial background medication in SLE with actions in many molecular pathways. It has disease specific effects in reducing flare, treating cutaneous disease and inflammatory arthralgias in addition to other effects such as reduced thrombosis, increased longevity, improved lipids, better glycemic control and blood pressure. Dehydroeipandrosterone is also an immunomodulator in SLE which can have positive effects on disease activity and has bone protective properties. This review outlines the immunologic actions of these drugs and the clinical evidence supporting their use.

Abstract
Systemic lupus erythematosus (abbreviated SLE or lupus) is a systemic autoimmune disease, with genetic, immunologic, hormonal, and environmental factors. 1 One of the environmental factors that has been studied over the years is vitamin D, which is created in the human body in response to exposure to sunlight and ultraviolet (UV) radiation. This review aims at examining findings from recent years, specifically 2013–2014, regarding the relationship between vitamin D deficiency and SLE flares, severity, and clinical manifestation, as well as to examine the treatment options derived from this relationship.

Cistromic and genetic evidence that the vitamin D receptor mediates susceptibility to latitude-dependent autoimmune diseases. Genes Immun 2016; 17:213-9.

Abstract
The vitamin D receptor (VDR) is a ligand-activated transcription factor that regulates gene expression in many cell types, including immune cells. It requires binding of 1,25 dihydroxy vitamin D3 (1,25D3) for activation. Many autoimmune diseases show latitude-dependent prevalence and/or association with vitamin D deficiency, and vitamin D supplementation is commonly used in their clinical management. 1,25D3 is regulated by genes associated with the risk of autoimmune diseases and predominantly expressed in myeloid cells. We determined the VDR cistrome in monocytes and monocyte-derived inflammatory (DC1) and tolerogenic dendritic cells (DC2). VDR motifs were highly overrepresented in ChIP-Seq peaks in stimulated monocyte (40%), DC1 (21%) and DC2 (47%), P<E(-100) for all. Of the nearly 11 000 VDR-binding peaks identified across the genome in DC1s, 1317 were shared with DC2s (91% of DC2 sites) and 1579 with monocytes (83% of monocyte sites). Latitude-dependent autoimmune disease risk polymorphisms were highly overrepresented within 5 kb of the peaks. Several transcription factor recognition motifs were highly overrepresented in the peaks, including those for the autoimmune risk gene, BATF. This evidence indicates that VDR regulates hundreds of myeloid cell genes and that the molecular pathways controlled by VDR in these cells are important in maintaining tolerance.

Abstract
Osteoporosis (OP) and fragility fractures (FFx) are a known comorbidity in patients with systemic lupus erythematosus (SLE). This work aimed at evaluating (1) the prevalence of OP and FFx in a cohort of SLE and (2) the risk factors associated with both OP and FFx. The following data were collected from clinical charts: age, sex, menopausal status (MP), body mass index, smoking habits, disease duration, daily dose and cumulative glucocorticoids (GCs), type of organ involvement, comorbidities and medications. Data on bone metabolism, calcium and vitamin D supplementation and treatment with bisphosphonates, teriparatide or denosumab were collected, together with bone mineral density (BMD) values (measured by dual-energy X-ray absorptiometry (DXA)) and history of FFx (occurred after the onset of SLE and unrelated to trauma). OP and reduced BMD were defined according to the WHO. 186 patients were included (women 175, men 11; mean age 46.4±13 years, mean disease duration 14.9±9 years). At their last visit, 97 patients (52.2%) had a reduced BMD and 52 (27.9%) had OP. 22 patients (11.8%), all women, had at least one FFx; six patients (27.3%) were pre-menopausal. On univariate analysis, age, cumulative dose of GC, MP, therapy with antiepileptics and chronic renal failure (CRF) were correlated with OP (p<0.03); age, total amount of GC, MP, CRF, anticoagulants (AC) and antiepileptic therapy were correlated with FFx (p<0.05). The multivariate logistic model confirmed a direct association of OP and age, MP and antiepileptic therapy (p≤0.01) and of FFx and age, chronic therapy with AC and antiepileptics (p<0.03). In conclusion, low BMD is frequently observed in SLE, and FFx are observed also in premenopausal patients. Together with traditional risk factors (age, MP and GC), CRF and chronic treatments with AC or antiepileptics seem to be associated with a higher risk profile for OP and FFx occurrence.

Abstract
BACKGROUND Vitamin D deficiency has been associated with systemic lupus erythematosus (SLE), but there is no consensus on the role of serum vitamin D in evaluating or predicting disease activity. This study aimed to demonstrate the direct correlation between vitamin D level and pediatric-onset SLE disease activity by a retrospective cohort study design. PATIENTS AND METHODS Thirty-five patients with pediatric-onset SLE and paired sera at the active and inactive disease states were enrolled. Disease activity was defined by Systemic Lupus Erythematosus Disease Activity Index 2000, and active lupus nephritis (LN) was defined as active urine sediment, and proteinuria >2+ on stick or >500 mg/day. All data were reviewed and calculated from previous medical records. The levels of both vitamin D2 and vitamin D3 were checked by electrochemiluminescence immunoassay. RESULTS Serum 25-hydroxyvitamin D (25-OH D) levels in the active status were significantly lower compared to that in inactive disease status (12.0 ± 7.2 ng/mL vs. 15.4 ± 7.4 ng/mL, p = 0.005). A subgroup analysis revealed that at active disease status, patients with LN had lower 25-OH D levels than patients without LN (16.3 ± 8.2 ng/mL vs. 9.8 ± 5.6 ng/mL, p = 0.023). Moreover, there is a significant inverse correlation between serum 25-OH D levels and Systemic Lupus Erythematosus Disease Activity Index 2000 at both inactive (r = -0.335, p = 0.003) and active (r = -0.373, p = 0.016) disease status. CONCLUSION Serum vitamin D levels are inversely correlated with SLE disease activity at both active and inactive disease status, and also with the presence of LN at active disease stage.

Abstract
BACKGROUND Vitamin D receptor is constitutively expressed on the lymphocyte surface. Recent studies highlight that vitamin D may exert actions on T-cells, inhibiting Th1 and Th17 response and enhancing Th2 and T-regulatory (T-reg) function. METHODS Thirty-four patients with systemic lupus erythematosus (SLE) were randomly enrolled in a two-year prospective study. In the first year, 16 patients were supplemented with an intensive regimen of cholecalciferol (IR) (300.000 UI of cholecalciferol at baseline and 50.000 UI/monthly as maintenance, 850.000 UI annually), whereas 18 with a standard regimen (SR) (25.000 UI of cholecalciferol monthly, 300.000 UI annually). During the second year, patients were switched to the other arm of treatment. Phenotypic analysis of peripheral T lymphocyte and the quantification of cytokine production from peripheral blood mononuclear cells (PBMCs) were evaluated by flow cytometry. RESULTS At baseline, no significant difference between the two groups emerged among main T-cell subtypes. Over two years of treatment, we saw an increase in the number of T-reg cells, in the total amount of CD4+CD45RA+CCR7- T-cells, whereas a significant reduction of CD8+CD28- T-cells was observed. In addition, the analysis of PBMCs from eight patients following the IR showed the reduction of the IFN-γ/IL-4 ratio (p = 0.01) among CD8+ T-cells after 12 months. CONCLUSIONS After a long-term of monthly treatment with vitamin D in SLE patients, an enhancement of T-reg cells and the production of Th2 cytokines should be expected.

Abstract
BACKGROUND Low vitamin D (vit.D) serum levels are common in patients with systemic lupus erythematosus (SLE) and seem to correlate with higher disease activity. We investigated the effects of different regimens of vit.D supplementation in SLE patients with inactive disease. METHODS This 24-month prospective study included 34 SLE women who were randomized to receive, together with their ongoing treatment, a standard regimen (SR) of cholecalcipherol (25,000 UI monthly) or an intensive regimen (IR) (300,000 UI initial bolus followed by 50,000 UI monthly) for one year and then were switched to the other regimen in the second year. Patients were seen quarterly for assessment of 25-OH vit.D levels, disease activity, SLE serology and bone metabolism markers. RESULTS By intra-patient comparison, only the IR was found able to significantly raise vit.D serum levels. After 12 months, values above 30 ng/ml were found in 75% of patients in IR while in only 28% in SR. No significant differences in disease activity and SLE serology were found at any time point between SR and IR. No changes in the mineral metabolism were observed. CONCLUSIONS The IR was safe and effective in obtaining sufficient levels of vit.D in most SLE patients. However, both regimens of supplementation did not differently affect disease activity nor SLE serology.

Abstract
PURPOSE OF REVIEW This manuscript will provide a review of recent publications, examining the correlation of systemic lupus erythematosus (SLE) with changes in bone health and associated osteoporosis, highlighting prevalence, etiology, diagnosis, and treatment. RECENT FINDINGS Studies suggest that bone loss and fractures are associated with SLE, related not only to the disease itself, but also with low vitamin D and treatment side-effects. Understanding the mechanisms of glucocorticoids on bone and the immunologic relationship of vitamin D, as well as recognizing the role of chronic inflammation on bone, allows for better understanding of skeletal side-effects. Further awareness of the association of poor bone health has led to an increased need for prevention and treatment. New imaging and treatment are emerging, although not recommended currently. SUMMARY Loss of bone density culminating in osteoporosis and fracture is a frequent comorbidity in SLE patients at any age and is multifactorial in etiology. Awareness and diagnosis is crucial because of its prevalence and morbidity. Prevention is safe and effective in this high-risk population where diagnostic measures and interventions are underutilized and guidelines are lacking.

Abstract
Vitamin D plays key roles as a natural immune modulator and has been implicated in the pathophysiology of autoimmune diseases, including systemic lupus erythematosus (SLE). This review presents a summary and analysis of the recent literature regarding immunoregulatory effects of vitamin D as well as its importance in SLE development, clinical severity, and possible effects of supplementation in disease treatment.
