An Exploration of Some Predictors of Quality of Life-Related to the Innate Immune System, Inflammation, and Disease Activity in Patients with Behcet's Syndrome: An Analytical Cross-sectional Study. Curr Rheumatol Rev 2024; 20:200-207. [PMID: 37691223 DOI: 10.2174/1573397119666230907101558] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2023] [Revised: 06/05/2023] [Accepted: 07/19/2023] [Indexed: 09/12/2023]
Abstract
BACKGROUND Behçet's disease (BD) has a growing prevalence in Silk Road countries. The aim of our cross-sectional study was to explore the clinical and molecular predictors of quality of life in BD patients. MATERIALS AND METHODS One hundred and fifty consecutive Iranian BD patients with an age range between 20-50 years were included. The Leeds Behçet's disease quality of life (BDQoL) in Persian form was fulfilled to evaluate the quality of life. Anthropometric measurements were carried out using the calibrated scales. Iranian Behcet's Disease Dynamic Activity Measure (IBDDAM), Behcet's disease current activity form (BDCAF), and Total Inflammatory Activity Index (TIAI) were used to assess BD activity. mRNA expression of toll-like receptors 2 and 4 (TLR2 and TLR4) and tumor-necrosis-factor-alpha (TNF-α) levels in serum were measured by real-time polymerase chain reaction (PCR) and ELISA, respectively. Multiple linear backward regression at P = 0.1 was used to study the potential predictors of quality of life. RESULTS TLR2 and BDCAF were shown to be the most important predictors of quality of life in BD patients by 22%. There were positive associations between them (β = 0.326, p = 0.013 for BDCAF; β = 0.366, p = 0.006 for TLR2) and BDQoL value. CONCLUSION Higher TLR2 expression as a key protein in recognizing pathogens by innate immunity and BDCAF value as a comprehensive BD assessing scale contribute to poor quality of life among BD patients. Emphasizing therapeutically, approaches associated with lower TLR2 expression and BDCAF value can be considered in future studies.

Abstract
Behcet's disease is a chronic vasculitis of unknown etiopathogenesis. Serum vitamin D levels have been reported to be associated with a variety of inflammatory and autoimmune diseases one of which is Behcet's disease. The previous studies about vitamin D in Behcet's disease seem to be focused on 4 main categories; the studies evaluating serum vitamin D levels between patients with Behcet's disease and controls, the studies evaluating serum vitamin D in the susceptibility and pathogenesis of Behcet's disease, the studies evaluating serum vitamin D in clinical involvements and activity of Behcet's disease, and the studies evaluating the effect of serum vitamin D replacement in Behcet's disease. The aim of this manuscript was to evaluate the results of the studies on serum vitamin D in Behcet's disease and review the literature.

Abstract
OBJECTIVE The aim of this study was to investigate whether the gene polymorphisms of vitamin D receptor (VDR) had a genetic effect on the susceptibility of Behcet's disease (BD). MATERIAL AND METHODS We conducted a meta-analysis emphasizing the association between the VDR gene polymorphisms and the risk of BD. The strength of the association in five genetic models was assessed by pooled odds ratios (OR) with a corresponding 95%confidence interval (CI). RESULTS A total of seven independent comparisons with 478 cases and 666 healthy controls were included in this meta-analysis. The overall results suggested that a significant association between ApaI polymorphism and BD risk was found in allele comparison, recessive model, and homozygote model among total populations. Subgroup analysis indicated that a significant association of ApaI polymorphism in the development of BD existed under the allelic model among Africans, while for Caucasians, a similar link was identified in the recessive model and homozygote model. Regarding Bsml polymorphism, an obvious relationship was detected to be significant in allele comparison and recessive model in the Caucasian population. Interestingly, the Fokl variant decreased the risk of BD in Africans under five genetic models, while it increased the risk in Caucasians across the recessive model and homozygote model. CONCLUSION The results of this meta-analysis provide evidence of the link between the four widely studied polymorphisms in the VDR gene and BD, indicating a robust estimate of the genetic risk.

Abstract
OBJECTIVE Behcet's disease (BD) is a chronic multisystem inflammatory disease classified as Variable Vessel Vasculitis with unclear etiology. We designed this systematic review and meta-analysis to evaluate vitamin D status in Behcet's disease patients with this background. METHODS We performed this systematic review and meta-analysis according to (PRISMA) guidelines. We included all observational studies in humans published in English, evaluating the association of 25(OH)D concentrations in Behcet's patients. Two reviewers (HRK and AE) independently searched the databases and screened articles based on their titles and abstracts. A third reviewer resolved all disagreements. We performed analysis using Cochrane Program Review Manager Version 5.3. The protocol for this review was registered on PROSPERO (CRD42020197426). RESULTS A total of 341 publications were initially identified according to the search strategy. Finally, 12 publications were included in the meta-analysis. We performed this meta-analysis on 1265 participants from different studies with a sample size from 63 to 224 individuals. In studies comparing Active and Inactive subgroups of patients with Behcet's Disease, we found a significantly lower serum level of vitamin D in patients with Active BD (-0.4; 95%CI: -0.61, -0.25; p<0.00001). We found that the serum level of vitamin D in Behcet's Disease is significantly higher than Health Controls (0.5; 95%CI: 0.15, 0.50; p=0.00001). CONCLUSION We demonstrated that the existing evidence is consistent with the hypothesis that an increased serum level of vitamin D would be associated with substantially lower risk of active Behcet's disease.

Abstract
BACKGROUND No epidemiologic study has previously reported on the associations among Behçet's disease (BD) and autoimmune disorders. OBJECTIVES To investigate the association between BD and the autoimmune disorders multiple sclerosis and rheumatoid arthritis. METHODS Medical records of patients newly diagnosed with BD (n = 6,214) in 2012-2017 were analyzed using data entered into a large, nationwide database from 2007 to 2017. An age- and sex-matched control population of individuals without BD was sampled at a ratio of controls:BD cases of 3:1 (n = 18,642). Both cohorts were analyzed for the presence of multiple sclerosis or rheumatoid arthritis within a minimum of 5 years prior to their BD diagnosis. RESULTS Patients with BD had significantly higher odds ratios (ORs) for multiple sclerosis (8.85 [95% CI 2.36-33.17]) and rheumatoid arthritis (4.62 [95% CI 3.35-6.35]) than the control group after adjustment for diabetes mellitus, hypertension, and dyslipidemia. BD patients aged <40 years had a higher proportion of rheumatoid arthritis (OR 23.91, 95% CI 5.50-103.9) than older patients (OR 3.96, 95% CI 2.83-5.54). CONCLUSION Our results suggest that BD is associated with multiple sclerosis and rheumatoid arthritis.

Abstract
BACKGROUND & AIM Previous studies showed a vitamin D deficiency in patients with Behçet's disease, suggesting potential benefits of vitamin D supplementation in the prevention and treatment of Behçet's disease. Interpretation of these studies may be limited by reverse causality or confounding bias. We aim to determine the causal association between serum 25-hydroxyvitamin D [25(OH)D] and the risk of Behçet's disease by Mendelian randomization. METHODS An allele score formed by four variants (rs2282679, rs10741657, rs12785878 and rs6013897) that were associated with serum 25(OH)D level, was examined using data of genome-wide association study (GWAS) on 999 Behçet's disease and 4417 healthy individuals of Chinese ancestry and validated using data of GWAS on 1215 Behçet's disease and 1278 controls of Turkish ancestry. The primary outcome was the risk of Behçet's disease, evaluated by an inverse variance weighted average of the associations with genetically determined 25(OH)D levels. RESULTS The inverse variance weighted estimate showed that genetically increased 25(OH)D level was associated with a higher risk of Behçet's disease. In the Chinese cohort, the odds ratio for Behçet's disease in one standard deviation increase of natural log-transformed 25(OH)D level was 3.82 (95% CI: 1.27-11.42). Data from Turkish cohort confirmed the association with Behçet's disease (OR, 95% CI: 4.18, 1.15-15.12). In overall combination of Chinese and Turkish cohorts, the odds ratio for Behçet's disease per standard deviation increase of natural log-transformed 25(OH)D level was estimated to be 3.96 (95% CI: 1.72-9.13; P = 0.001). No significant evidence of pleiotropy and heterogeneity was detected. CONCLUSIONS On the basis of evidence in 7909 human beings, this study provides the newest indication that a lifelong higher 25(OH)D level is associated with an increased risk of Behçet's disease. Special attention should be paid to the potential harm of long-term or high-dose use of vitamin D supplements in clinical practice.

Abstract
BACKGROUND Recurrent aphthous stomatitis is one of the most prevalent oral mucosa diseases and the etiology is unclear. As a potent anti-inflammatory and immunomodulating agent, vitamin D can significantly affect oral cavity homeostasis. However, to the best of our knowledge, no study has been conducted in pediatric population on the potential role of vitamin D in recurrent aphthous stomatitis to date. The aim of the present study is to determine the vitamin D status in recurrent aphthous stomatitis in children. METHODS This study is conducted retrospectively. Seventy-two patients with minor recurrent aphthous stomatitis and 70 age-matched healthy controls included in the study. 25-Hydroxyvitamin D levels were measured in all patients using enzyme immunoassay. RESULTS Serum vitamin D levels were 16.4 (8.6) ng/mL in patient group and 23.1 (11.5) ng/mL in healthy controls. There was a statistically significant difference between the groups in terms of serum vitamin D levels (P = .002). There was no significant correlation between serum vitamin D levels and the severity of the recurrent aphthous stomatitis (r = 0.54, P = .76). CONCLUSIONS Our study showed a significant difference in vitamin D levels between patients with recurrent aphthous stomatitis and the healthy control group. We also found no correlation between vitamin D status and the severity of the disease.

Abstract
Various tissues and cell types are the targets of vitamin D. However, the major targets of vitamin D in the immune system are monocytes/macrophages, dendritic cells (DCs), as well as B and T cells. Vitamin D plays an important role in the immune system modulation via regulating the expression of genes that generate pro-inflammatory mediators and inhibiting the proliferation of pro-inflammatory cells, both of which have been implicated in the pathophysiology of the inflammatory diseases. Recent studies have revealed the important relations between vitamin D and Behçet's disease (BD). Vitamin D function and its deficiency have been linked to a wide range of metabolic disorders including malignant, cardiovascular, infectious, neuromuscular, and autoimmune diseases. Here, we provide a brief analysis of the recent literature regarding immune-regulatory effects as well as clinical evidence of vitamin D influence on the molecular level in BD.

Abstract
Aim: In the present study, the evidence about the association between vitamin D deficiency and Behcet's disease activity was systematically reviewed and meta-analyzed. Method: We searched the English and Persian databases of Medline (Ovid), CINHAL, Scopus, Proquest, the Cochrane library and SID, IranDoc, Magiran, Iran Medex for articles published up until May 2018 with the keywords were related to serum vitamin D and active and inactive Behcet's disease in adults. Meta-analysis was done using the CMA software. Results: A total of 138 titles were retrieved and reduced to 80 titles after deletion of duplicates and finally after close assessing of titles and abstracts eight eligible studies including a total of 939 participants were identified for systematic review and meta-analysis. According to the results of the meta-analysis, the pooled effect size of the differences in the serum level of vitamin D in patients with inactive Behçet's Disease and healthy controls was [OR:-0.05; 95% CI:-2.05, 1.94; p = 0.95]. The serum vitamin D level was significantly lower in active patients compared with healthy controls [OR:1.21; 95%CI: -0.12, 2.31; p = 0.03]. The pooled effect size of the differences in the serum level of vitamin D in active and inactive Behçet's Disease was [OR:-0.71; 95%CI: -1.41, -0.007; p = 0.04] Conclusion: There is an association between vitamin D deficiency and active Behçet's Disease. Future studies investigating the association of vitamin D deficiency and Behçet's Disease needs to involve following information: dietary intake of calcium and vitamin D, measuring of sun exposure, report of drug consumption and physical activity level.

Abstract
Introduction Recurrent aphthous stomatitis (RAS) is a common chronic inflammatory oral mucosa disease with an unknown cause. However, dysregulation of the immune response seems to play an important role in this disease. Aim To evaluate the vitamin D status in RAS patients and its effects on RAS severity, given the likely immunomodulatory function of vitamin D in the human organism. Material and methods Sixty-six patients with RAS and 66 controls were examined. Immunomodulatory or immunosuppressive treatment and other ulcerative oral diseases were used as exclusion criteria. The severity of RAS was assessed according to the clinical classification of the disease, the number of lesions per flare-up and the length of intervals between the attacks. The serum vitamin D level was established in each participant. Results The mean serum vitamin D (25(OH)D) levels were found to be 16.81 ng/ml in the study group and 19.22 ng/ml in the control group, with no statistically significant difference between the two groups. In the study group, 5 (7.6%) participants were diagnosed with the “normal” vitamin D levels, while 16 (24.2%) had “insufficient” levels and 45 (68.2%) had “deficient” levels. The corresponding distribution in the control group was 8 (12.1%), 18 (27.3%) and 40 (60.6%), respectively. There was no statistical significance in the difference of vitamin D deficits between the study and the control groups. No correlation was detected between the severity of RAS and the serum vitamin D level. Conclusions Vitamin D does not seem to be a trigger factor for RAS occurrence and does not appear to influence the severity of the disease in the studied group.

Abstract
Vitamin D plays a significant role in the immune system modulation and may confer a protective role in autoimmune diseases. We conducted a case-control study to compare 25(OH)D levels in patients with BD who were managed at a regional rheumatology programme in the midwest region of Ireland compared to matched controls. Healthy controls were selected from the Irish health system and matched in 1 : 5 ratio for age, sex, and the month of the year. 25(OH)D levels <20 nmol/L were classified as deficient while levels between 20 and 40 nmol/L were classified as insufficient. Differences between groups were assessed using Mann-Whitney test and associations between cases and controls were expressed as odds ratios and 95% confidence intervals. Nineteen patients with BD were compared with 95 controls matched by age, sex, and month of blood draw. 25(OH)D levels were significantly higher in patients in BD than in matched controls (median values: 45 nmol/L versus 22 nmol/L, p < 0.005) and tended to be lower in patients with active disease than in those without (median values: 35 nmol/L (IQR: 22.75-47.25 nm/L) versus 50 nmol/L (IQR: 35-67 nmol/L), p = 0.11). Compared to controls, patients with BD were significantly less likely to have 25(OH)D deficiency or insufficiency (OR: 0.09, 95% CI: 0.03-0.28, p < 0.001). Our findings suggest a possible role for 25(OH)D in modifying the inflammatory response in BD and uncover a potential opportunity to assess whether correction of Vit D deficiency confers protective benefits.

Abstract
Introduction Immune mechanisms have been implemented to have a role in the pathogenesis of Behçet’s disease (BD) and vitamin D has been shown to have a regulatory role in the immune system function. Aim To evaluate the vitamin D levels of BD patients and its relationship between clinical findings and disease activity of BD. Material and methods Sixty-eight patients with BD and 70 age- and sex-matched controls were examined retrospectively. Demographic features, vitamin D levels for both groups and clinical findings, disease activity, drug usage for BD patients were examined from their medical reports. Disease activity was calculated for each patient according to Krause’s BD activity assessment. Results Mean vitamin D levels of patients and controls were 15.35 ±7.18 ng/ml and 18.44 ±5.79 ng/ml, respectively. Vitamin D levels were significantly lower in BD patients than in controls (p = 0.006). Mean vitamin D levels of active and inactive BD cases were 15.68 ±7.31 ng/ml and 15.08 ±7.17 ng/ml, respectively (p = 0.73). Disease activity of patients using and not using vitamin D was similar (p = 0.51). Conclusions Significantly lower levels of vitamin D were observed in BD patients. Our results indicate that there is no correlation between BD activity and a vitamin D level. Together with these, vitamin D replacement treatment was found to have no effect on disease activity.

Abstract
Vitamin D belongs to a group of fat-soluble secosteroids which assume many roles in the human organism. In humans the most important forms are vitamin D3 and vitamin D2. Their primary function is the regulation of the calcium and phosphorus balance, which promote the growth of healthy bony tissue. Studies over the past few years have revealed a much wider role of vitamin D involving the aging processes, carcinogenesis, the carbohydrate balance as well as the effects on the course of various infections. In this paper we discuss the basic functions of vitamin D in the human body and the mechanisms of its activity and we summarize recent reports on the impact of vitamin D on the oral cavity with a special emphasis on autoimmunologic diseases, including: recurrent aphthous stomatitis, Behçet syndrome and Sjögren syndrome.

Abstract
OBJECTIVE Takayasu's arteritis (TAK) is a chronic, large-vessel vasculitis. Vitamin D, as a steroidal hormone, has recently been shown to have immunoregulatory and immunosuppressive effects. Low vitamin D levels are demonstrated in various autoimmune disorders. The aim of this study is to investigate vitamin D levels in patients with TAK. A comprehensive review of vitamin D levels in systemic vasculitides (SVs) is also performed. METHODS The study included 36 patients with TAK, 28 patients with Behçet's disease (BD) as disease control and 30 sex-matched healthy controls. Plasma 25-hydroxy vitamin D (25(OH) vit D) levels were measured with high-performance liquid chromatography. "Deficiency" was defined as 25(OH) vit D levels below 25 nmol/l and "insufficiency" as below 50 nmol/l. RESULTS Plasma 25(OH) vit D levels were significantly lower in TAK patients (16.93 ± 10.62 nmol/l) than healthy controls (64.63 ± 21.82 nmol/l). Vitamin D level in BD patients (38.8 ± 20.9 nmol/l) is lower than healthy controls but higher than TAK patients. The frequency of vitamin D deficiency was 83.3% in patients with TAK compared to 3.3% in healthy controls. Plasma 25(OH) vit D levels were same between clinically active and inactive patients. In literature review, very few studies were found to investigate vitamin D in SVs. CONCLUSION We observed a high prevalence of vitamin D deficiency in patients with TAK. As various immune effects of vitamin D on mononuclear cells and arterial endothelium is shown, vitamin D deficiency can be a predisposing factor for immune activation in SV. We therefore suggest monitorization and replacement of vitamin D status in all TAK and other SV patients.

Abstract
OBJECTIVES The aim of our study was to investigate the association of four polymorphisms of the VDR gene (FokI, BsmI, TaqI, and ApaI) with their susceptibility to Behçet's disease (BD) and their clinical manifestations with respect to the Iranian Azari population. METHOD In this cross-sectional study we considered the BsmI, FokI, ApaI, and TaqI polymorphisms in 50 Iranian Azary patients with BD and 50 healthy controls, with the use of polymerase chain reaction (PCR) restriction fragment length polymorphism (RFLP). RESULTS A significant difference was found for the FokI polymorphism between the case and control groups. The f allele frequency of 26% was present in BD patients, compared to only 13% in the control group. In addition, the f/f genotype was significantly associated with BD. We found no significant differences between the BD and control groups regarding the distribution of ApaI, BsmI, and TaqI genotype frequencies. We found no association between VDR polymorphisms and the clinical manifestations of BD. CONCLUSIONS The VDR f allele and f/f genotype are associated with BD in the Iranian Azari population.
