Abstract
Background Many studies have investigated the relationship between the interleukin-1β
gene (IL1B) −511C/T polymorphism and the risk of Behçet’s
disease (BD); however, the conclusions remain controversial. Methods In this study, we systemically retrieved relevant studies from the Chinese
Biomedicine Database, China National Knowledge Infrastructure, Embase,
Cochrane Library, and PubMed databases. We then calculated the odds ratios
(ORs) and 95% confidence intervals (CIs) using the meta-package Stata
version 12.0. Results The IL1B −511C/T polymorphism was not related to BD
susceptibility using any of the tested models (C vs T: OR = 1.20, 95%
CI = 0.97–1.49; CC vs TT: OR = 1.27, 95% CI = 0.95–1.70; CT vs TT:
OR = 1.03, 95% CI = 0.781.36; dominant model: OR = 1.12, 95% CI = 0.87–1.46;
recessive model: OR = 1.27, 95% CI = 0.89–1.82). Similarly, subgroup
analysis including studies consistent with the Hardy–Weinberg equilibrium
revealed no association between the IL1B polymorphism and
BD susceptibility. Conclusion This meta-analysis indicates that the IL1B −511C/T
polymorphism is unlikely to affect the risk of BD; however, further
large-scale, carefully designed studies are needed to verify these
results.

Abstract
Background Behcet’s disease (BD) is a complex, inflammatory, immune-mediated multi-systemic disease of unknown etiology. Cytokines play major roles in the pathophysiology of BD, and its production may be affected by polymorphism in cytokine genes. Hence, the present study was planned to investigate any possible association between the polymorphism in TGF-β, IFN-γ, and IL-6 genes and BD in the Saudi population. Materials and Methods The present study includes 79 BD cases and 117 age-matched controls. Polymerase chain reaction with restriction fragment length polymorphism (PCR-RFLP) and amplification refractory mutation systems (ARMS) PCR methods were used for polymorphic analysis. Results The heterozygous (CT) and (CT+TT) combined genotypes of TGF-β (509-C/T), heterozygous (AT), variant (TT), and (AT+TT) combined genotypes of IFN-γ (874-A/T) were significantly (P<0.05) associated with BD in the Saudi population. No significant differences were observed for IL-6 (174-G/C) genotypes and alleles between BD cases and controls. Gender does not reflect any significant genotypic and allelic association with males and females. Conclusion CT genotype of TGF-β, and AT and TT genotypes of IFN-γ could be associative genetic risk factors for BD in Saudis. Regulatory region polymorphism in cytokines gene can increase inflammation and deregulated immune response, which could be risk factor for BD.

Evaluation of the relationship between Behcet's disease and cardiovascular disorders through metabolic function and copeptin. Postepy Dermatol Alergol 2019; 36:609-615. [PMID: 31839779 PMCID: PMC6906967 DOI: 10.5114/ada.2019.89509] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2017] [Accepted: 06/15/2018] [Indexed: 11/17/2022] Open
Abstract
Introduction Behcet's disease (BD) is a chronic inflammatory and multisystem vasculitis. Cardiac involvement is one of the major complications of BD. Cardiac involvement is sporadic in terms of its specific relationship to mortality. How to identify and follow up on cardiac-related complications in BD patients has yet to be determined. Aim The aim of our study is to assess cardiovascular diseases in BD patients by measuring metabolic function and copeptin levels and comparing these to a healthy control group. Knowing the specific metabolic functions that are negatively affected by BD will help doctors determine which functions need to be more closely monitored in BD patients. Our study is the first study in the available literature that evaluates copeptin in BD patients. Material and methods A control group of 58 healthy volunteers, including 32 females and 26 males (average age: 39.8 ±10.3 years, range: 18-50 years), was formed to compare with 84 BD patients (average age: 40.5 ±11 years, range: 21-63 years), including 39 females and 45 males. Diastolic and systolic blood pressure, height, weight, body mass index (BMI), and waistline were measured for both groups. All study patients were also given hemograms, and fasting blood sugar (FBS), uric acid, lipid profile, insulin, C-reactive protein (CRP), and copeptin levels were measured. An ELISA Kit was used to measure copeptin. Results FBS, CRP, and insulin levels were significantly higher in the patient group (p < 0.001, p = 0.004, and p = 0.038, respectively). Patients who had had the disease for more than 10 years had higher BMIs, total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride (TG) levels (p = 0.034, p = 0.004, p = 0.016, and p = 0.045, respectively). Additionally, CRP levels were found to be higher in long-term patients and patients with active lesions. Diastolic blood pressure and waist circumference were also higher in the BD group. Patients who had active lesions had significantly higher diastolic blood pressure (p = 0.047). There were no statistically significant differences in copeptin levels between BD and control groups. Conclusions Cardiovascular involvement rarely contributes to the high mortality rate of BD patients. There were meaningful elevations in metabolic markers identified when BD and cardiovascular disease risk was assessed with metabolic parameters. The cardiac disease risk should be closely followed using metabolic functions, particularly in long-term BD patients with vascular involvement.

Abstract
BACKGROUND Biologics are increasingly used in management of Behçet's Disease (BD) including ocular BD, but the evidence base is limited, mostly from studies of uveitis and BD manifestations. OBJECTIVE To review the evidence base for biologics in the treatment of ocular BD. METHODS Systematic literature search was made using exploded key words-Behçet's, ocular, biologics in MEDLINE, Cochrane library, Database of Abstracts Reviews and Effects, Clinical Trials.gov, Science Direct and Google Scholar. There was no limitation on region, language or date (Search updated 16th October 2018). Literature retrieval was restricted to randomised controlled trials (RCTs) of biologics. RESULTS Of 237 papers retrieved, eight met the inclusion criteria. RCTs on interferon alpha 2a (INF-α 2a), adalimumab, secukinumab, gevokizumab, rituximab and daclizumab were retrieved (two for adalimumab and gevokizumab). The outcome measures were not met for secukinumab, daclizumab and gevokizumab. Rituximab and INF-α 2a showed promising preliminary results but sufficiently powered RCTs are needed to provide adequate evidence of efficacy. The RCTs on adalimumab did not evaluate efficacy for BD uveitis specifically, hence are of limited value for this review. CONCLUSION Some biologics show promise in treating BD uveitis, but more RCTs are needed for firm conclusions about efficacy. A phase IV study or, registry of adalimumab could provide data on its efficacy in BD uveitis compared to other forms.

Abstract
BACKGROUND Behçet disease is a prototypical systemic autoimmune disease, caused by a complex interplay between environmental and genetic factors. The transmembrane immunoglobulin and mucin domain-3 (TIM-3) is a distinct member of the TIM family that is preferentially expressed on Th1 cells and plays a role in Th1-mediated autoimmune or inflammatory diseases, such as Behçet disease. OBJECTIVE The aim of this study was to test the potential association between TIM-3 gene polymorphisms and Behçet disease. METHODS Two single-nucleotide polymorphisms of TIM-3 (rs9313439 and rs10515746) were genotyped in 212 patients with Behçet disease and 200 healthy controls. Typing of the polymorphisms was performed using multiplex PCR amplification. RESULTS There were no significant differences in allele and genotype frequencies between the Behçet disease patients and controls who were successfully genotyped. Similar results were also found after stratification by gender, age, or clinical features. STUDY LIMITATIONS Lack of studies on various racial or ethnic groups and small sample size. CONCLUSION This study failed to demonstrate any association between the tested TIM-3 polymorphisms and Behçet disease.

Abstract
Behçet's disease (BD) is a chronic and rare multisystemic disorder defined by autoimmunity and inflammatory characteristics, manifested by ocular lesions, recurrent genital and oral ulcers, skin symptoms and arthritis as well as neurological, intestinal, and vascular involvement. Despite the unknown cause of BD, there is some strong documentation for immunological, genetic, environmental, and infectious factors playing a role in the pathogenesis of BD. While the nature of the genetic variants remains unidentified, many genetic risk factors are considered to contribute to BD susceptibility. Along with human leukocyte antigen gene encoding B*51 (HLA-B*51) and areas including the major histocompatibility complex class I, genome-wide association studies have recognized numerous other BD susceptibility genes including those encoding interleukin (IL)-10, IL-12 receptor β 2 (IL-12RB2), IL-23 receptor (IL-23R), C-C chemokine receptor 1 gene, signal transducer and activator of transcription 4 (STAT4), endoplasmic reticulum aminopeptidase (ERAP1), and genes encoding killer cell lectin-like receptor family members (KLRC4-KLRK1). It is believed that BD could be considered as a disorder lying in between autoimmune and autoinflammatory syndromes. The positive responses to classical immunosuppressive agents like azathioprine and cyclosporine and involvement of autoantigens in the initiation of the disorder are the main BD features that reflect the autoimmune nature of the disorder. In this review, we address recent findings on the role of common cytokines, antibodies and immunogenetic factors in BD.

Abstract
OBJECTIVES Recurrent aphthous stomatitis (RAS) is a chronic, ulcerative disease with a probable polygenic mode of inheritance and complex etiology with a strong immunological background. The aim of the present study was to determine the possible association between two single nucleotide polymorphisms (SNPs) of the IL-1β gene: IL-1β-511 T>C (rs16944) and IL-1β+3954C>T (rs1143634) and RAS susceptibility in a moderately large group of patients. DESIGN One hundred and four patients with minor, major and herpetiform RAS and 75 healthy volunteers were genotyped at IL-1β-511 T>C (rs16944) and IL-1β+3954C>T (rs1143634) using the PCR-RFLP approach. The results were statistically analysed with chi-square test and test of difference between two rates of structure, with p<0.05 assumed to be a statistically significance level (Statistica 10, StatSoft®, Kraków, Poland). RESULTS There were no statistically significant differences in the genotype distribution for the IL-1β C[+3954]T polymorphism between the RAS and control groups. The frequency of IL-1β*T[-511]/*T[-511] homozygotes among the patients was significantly higher when compared to our study control (p<0.0347). The results after stratification into carriers and non-carriers of C and T alleles did not clearly indicate which SNP may be considered a risk factor for RAS. CONCLUSIONS The genetic association between the studied SNPs of the IL-1β gene and RAS remains controversial and requires further investigation.

Abstract
PURPOSE This study aims to investigate the association of cytokine gene polymorphisms with the risk of Behcet's disease (BD) via comprehensive meta-analysis. METHODS The Embase and PubMed databases covering the period from the earliest possible year to May 2015 were searched. A total of 13 eligible articles including 2,065 BD patients and 1,559 controls were recruited. Odds ratios (ORs) and 95 % confidence intervals (CIs) were used to assess the strength of the associations. Potential publication bias was evaluated using Egger's linear regression test. RESULTS Meta-analysis indicated associations between IL‑6 rs1800795, IL‑12B rs3212227, and IL‑18 rs1946518 in all study subjects: IL‑18 rs1946518 in the dominant model (IL‑18 rs1946518: OR = 0.48, 95 % CI: 0.34-0.70, P = 0.000) and the homozygote model (IL‑18 rs1946518: OR = 0.40, 95 % CI: 0.25-0.65, P = 0.000); and IL‑6 rs1800795 and IL‑12B rs3212227 in the dominant model (IL‑6 rs1800795: OR = 0.53, 95 % CI: 0.39-0.72, P = 0.000; IL‑12B rs3212227: OR = 1.26, 95 % CI: 1.06-1.48, P = 0.007; IL‑18 rs1946518: OR = 0.46, 95 % CI: 0.33-0.65, P = 0.000). No significant evidence for associations of IL‑18 rs187238 polymorphisms with BD susceptibility was detected. CONCLUSION In summary, this meta-analysis finds that IL‑6 rs1800795 and IL‑18 rs1946518 polymorphisms decrease the risk of BD. However, IL‑12B rs3212227 increases BD susceptibility. Further large-scale investigation of this association is necessary.

Abstract
Continuous identification of specific targets and candidate genes together with novel approaches offers new promises for the future of gene therapy design in Behçet's disease (BD). Personalized medicine based on pharmacogenomics is being developed at the clinical stage to improve treatment response. Screening the whole gene and regulatory regions is important when searching for novel variants associated with such complex diseases. Different host genetic factors play significant roles in susceptibility to BD. Thus, identifying these genes responsible for susceptibility and resistance to BD may offer a notable contribution toward understanding its pathogenesis, and may lead to the development of novel prophylactic and treatment strategies. Evidenced-based treatment strategy is recommended for the management in BD patients. This review sheds light on the immunopathogenesis and pharmacogenetics of BD with special attention to the treatment targeting gene polymorphisms. In conclusion, the potential of genetically guided treatment in BD takes us back to the future for an accurate management strategy of this serious rheumatic disease. The ongoing discovery of pivotal genes related to the susceptibility, manifestations, disease activity and treatment options provide substantial hope to the reduced frequency of BD, effective control and improvement in the prognosis. Targeted gene therapy could be a leading option in the treatment armamentarium of BD.

Abstract
OBJECTIVES The purpose of this study was to evaluate whether a single-nucleotide polymorphism (SNP) IL12B 3(')UTR +1188A/C (rs3212227) confers susceptibility to several autoimmune diseases. METHODS A systematic literature search was conducted to identify relevant studies. Pooled odds ratio (OR) with 95% confidence interval (CI) was used to estimate the strength of association. RESULTS Twenty-five studies were included in the meta-analysis, which contained 9794 cases and 11,330 controls. Our result indicated that IL12B +1188A/C (rs3212227) polymorphism was associated with type-1 diabetes (T1D) in the dominant model (p = 0.008), and an increased risk was found in East Asians in the dominant model (p < 0.001). East Asians rheumatoid arthritis (RA) patients seemed to be at risk of allelic model (p = 0.011). As to Behcet's disease (BD), there was a risk in dominant model (p = 0.020) and positive associations of dominant model, allelic model in East Asians (p = 0.009; p < 0.001, respectively). But we failed to find any association between IL12B +1188A/C (rs3212227) polymorphism with Graves' disease (GD) and ankylosing spondylitis (AS). CONCLUSIONS The present study suggests that the IL12B +1188A/C (rs3212227) polymorphism might be associated with genetic susceptibility to autoimmune diseases, such as T1D, RA, BD, but not GD and AS.

Med Clin (Barc) 2015; 146:379-83. [PMID: 26654556 DOI: 10.1016/j.medcli.2015.09.017] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2015] [Revised: 08/13/2015] [Accepted: 09/10/2015] [Indexed: 11/16/2022]
Abstract
BACKGROUND AND OBJECTIVE This trial was designed to investigate the effects of the interleukin (IL)-1β, IL-1Ra, IL-2, IL-6, IL-10 gene polymorphisms on Behcet's disease (BD) occurrence and the association between the polymorphisms and the phenotype. MATERIALS AND METHOD The study population consisted of 71 patients and 70 age and gender-matched healthy subjects. Each of the participants had 2cc of blood withdrawn, which was placed into a whole blood tube, and the DNA was obtained using the NucleoSpin(®) Blood DNA Isolation kit. To display the band lengths, the products were amplified using the primary pairs of the interleukins investigated and developed in a 2% agarose gel. RESULTS There were no significant differences between the groups with respect to the IL-1Ra, IL-1β, IL-2, IL-6 and the IL-10 gene polymorphism distributions. In the patient group the IL-1RN2 gene polymorphism was detected to be statistically correlated with the presence of articular involvement (p=0.0283) and the IL-1β gene polymorphism was statistically correlated with the presence of an ocular lesion (p=0.0178). The evaluation of the IL-2 gene polymorphism (p=0.0065) and IL-10 gene polymorphism (p=0.0483) distributions with respect to age of BD onset revealed a statistically significant distribution. CONCLUSION The statistical correlations between the articular involvement and IL-1RN, the ocular involvement and the IL-1β, and the age of disease onset and the IL-2 and IL-10 gene polymorphisms, detected for the first time in the literature, suggest that these polymorphisms could be statistically associated with the disease symptoms and used as prognostic factors.

Abstract
Graves’ ophthalmopathy (GO) is the commonest extra-thyroidal manifestation of Graves’ disease (GD). Associations between interleukin-related (IL) gene polymorphisms and GO have been reported in different populations. We aim to confirm such associations by conducting a meta-analysis. Totally 382 publications were retrieved in MEDLINE and EMBASE up to 25/2/2015. After removing the duplicates and assessing the studies, we retrieved 16 studies that met the selection criteria for meta-analysis, involving 12 polymorphisms in 8 IL-related genes, and 1650 GO cases and 2909 GD controls. The summary odds ratio (OR) and 95% confidence intervals (CI) were estimated. We found one polymorphism in IL1A (rs1800587, c.-889C>T) showing a suggestive association with GO in the meta-analysis (allelic model [T vs. C]: OR = 1.62, 95% CI: 1.00–2.62, P = 0.050, I2 = 53.7%; recessive model [TT vs. TC + CC]: OR = 2.39, 95% CI: 1.07–5.37, P = 0.039, I2 = 23.6%; heterozygous model [TC vs. CC]: OR = 1.52, 95% CI: 1.04–2.22, P = 0.034, I2 = 37.0%). No association with GO was detected for the other 7 genes (IL1B, IL1RA, IL4, IL6, IL12B, IL13 and IL23R). Our results thus indicate that IL1A is likely to be a genetic biomarker for GO. Further studies with larger sample sizes are warranted to confirm the associations of IL1A and other IL-related genes with GO.

Abstract
Background Behçet's disease (BD), first described in 1937 as a triadic complex of symptoms (oral aphthae, genital ulcers, and hypopyon uveitis), is a chronic, relapsing, multisystemic idiopathic inflammatory disease. Objective The objective of this study was to investigate the usability of messenger RNA (mRNA) expression of cytokine genes for following up patients with BD and also assess polymorphisms in these genes as to how they influence mRNA expression. Methods This study investigated the role of the IL1A -889(C/T), IL1B -511(C/T), and IL2 -330(T/G) polymorphisms by polymerase chain reaction (PCR)-restriction fragment length polymorphisms and the expression levels of the genes by real-time PCR in BD. Results The frequency of the IL2 -330 G allele was found to be significantly higher in patients with BD. A decreased level of IL1A gene expression was found in the patient group with clinically active BD compared to controls. Increased IL1B gene expression levels werefound in patient groups with active, inactive, or ocular BD (p<0.001). IL2 gene expression level manifested no significant change compared to controls in the patient group with clinically active BD; it increased in the groups with clinically inactive BD or ocular involvement. Conclusion IL1A, IL1B, and IL2 gene expression, and IL2 promoter polymorphisms, may be valuable markers for predicting risk in the development of BD. We believe that the results reveal the importance of achieving a better understanding of BD and the prospects of developing future therapeutic strategies.

Abstract
Purpose To investigate the associations of single nucleotide polymorphisms (SNPs) of three genes (IL-12B, IL-12Rβ1 and IL-12Rβ2) in Behcet's disease (BD) and Vogt-Koyanagi-Harada (VKH) syndrome in a Chinese Han population. Methods A total of 806 BD cases, 820 VKH patients, and 1600 healthy controls were involved in this study. The first investigation included 400 BD patients, 400 VKH cases, and 600 healthy individuals. A second confirmatory study included a separate set of 406 BD patients, 420 VKH cases and another 1000 normal controls. Genotyping was carried out by PCR-restriction fragment length polymorphism assay and results were validated by using direct sequencing. The χ2 test was performed to compare the allele and genotype frequencies between cases and healthy controls. Results This study comprised two phases. In the first phase study, a significantly increased frequency of the rs3212227/IL-12B genotype CC and C allele was found in BD patients as compared to controls (Bonferroni corrected p value (pc) = 0.009, OR 1.8; pc = 0.024, OR 1.3, respectively). Moreover, the frequency of the C allele of rs3212227/IL-12B was also significantly increased in VKH patients (pc = 0.012, OR 1.3, 95% CI 1.1 to 1.6). No associations were found for the other seven tested SNPs either in BD or VKH disease. The second study as well as the combined data confirmed the significant association of rs3212227/IL-12B with BD (CC genotype: combined pc = 6.3×10−7, OR = 1.8; C allele: combined pc = 2.0×10−5, OR = 1.3, respectively) and the C allele frequency of rs3212227/IL-12B as the risk factor to VKH patients (combined pc = 2.5×10−5, OR 1.3, 95% CI 1.2 to 1.5). Conclusions Our study revealed that the IL-12B gene is involved both in the susceptibility to BD as well as VKH syndrome.

Abstract
OBJECTIVES Polymorphisms in the Interleukin (IL)-1-related genes at the locations -889, -511, + 3962 and mspa1l 1100 have been investigated for possible association with Behçet's disease (BD). METHODS A literature-based search was conducted to identify all relevant studies. Five independent studies from Turkish population met the included criteria. RESULTS IL-1α -889 CT [odds ratio (OR) = 0.72, 95% confidence interval (CI) = 0.55-0.95], IL-1α -889 TT (OR = 0.61, 95% CI = 0.40-0.93), IL-1β + 3962 C (OR = 1.41, 95% CI = 1.07-1.88), IL-1β + 3962 T (OR = 0.71, 95% CI = 0.53-0.94) IL-1β + 3962 CC (OR = 2.08, 95% CI = 1.08-3.99), IL-1β + 3962 CT (OR = 0.58, 95% CI = 0.38-0.88), IL-1 receptor antagonist (IL-1 Ra) mspa1l 1100 CT (OR = 0.69, 95% CI = 0.49-0.96), IL-1 Ra mspa1l 1100 TT (OR = 1.50, 95% CI = 1.08-2.08) had a significant association with BD. The pooled estimates for IL-1α -889 C, IL-1α -889 CC, IL-1α -889 T had a non-significant association with BD. CONCLUSIONS IL-1α -889 CT, IL-1α -889 TT, IL-1β + 3962 C, IL-1β + 3962 T, IL-1β + 3962 CC, IL-1β + 3962 CT, IL-1 Ra mspa1l 1100 CT, IL-1Ra mspa1l 1100 TT promoter polymorphisms may confer susceptibility to BD in Turkish population.

Abstract
OBJECTIVES Gout is caused by monosodium urate (MSU) crystal-induced inflammation of the joints and periarticular tissues. MSU crystals activate NALP3 and mediate interleukin (IL)-1β generation from its inactive pro-form, resulting in cellular activation and an IL-8-mediated neutrophil influx into the joint. IL-8 and IL-12 are important chemokines related to the initiation and amplification of acute and chronic inflammatory processes. In this study, we investigated whether the IL-8 -251T/A and IL-12 1188A/C polymorphisms are associated with susceptibility to gout in a Chinese Han male population. METHODS Overall, 387 patients with gout and 576 controls were included in this study. Genotyping was performed by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP). An association analysis was carried out using the χ2 test. A genotype-phenotype analysis was also conducted. RESULTS The T allele of IL-8 -251 was associated with risk of gout [p = 0.031 (odds ratio (OR) 1.229, 95% confidence interval (CI) 1.019-1.483]. There was a clear link between the IL-12 1188 AA and AC genotypic and A allelic frequencies between gout cases and controls (p < 0.001, df = 2 by genotype; p < 0.001, OR 1.404, 95% CI 1.165-1.691 by allele). CONCLUSIONS Our results suggest that the IL-8 -251T/A and IL-12B 1188A/C polymorphisms may be relevant host susceptibility factors for the development of gout.

Abstract
Behçet's disease (BD) is a chronic immune-mediated systemic disease, characterized by oral and genital lesions and ocular inflammation. Several cytokine genes may play crucial roles in host susceptibility to BD, because the cytokine production capacity varies among individuals and depends on the cytokine gene polymorphisms. The association of the interleukin (IL)-2 gene polymorphisms with the susceptibility to BD was investigated in this study. DNA samples were obtained from a Turkish population of 97 patients with BD and 76 healthy control subjects. Polymorphisms of IL-2 gene at position -330 and +166 were determined using the polymerase chain reaction with sequence-specific primers. In the patients with BD, there was a significantly increased frequency of IL-2 -330 GT genotype. Interestingly, we demonstrated that the frequencies of IL-2 -330 GT and IL-2 + 166 GG genotypes were increased in BD patients with ocular involvement, whilst IL-2 -330 TT genotype was significantly decreased. Also, analysis of allele frequency demonstrated that the presence of G allele at position +166 of IL-2 seems to be a risk factor for ocular involvement. These results reveal that IL-2 -330 GT genotype may be a susceptibility factor for BD, whereas IL-2 -330 TT genotype seems to display a protective association with BD. Additionally, IL-2 gene polymorphisms might be associated with ocular involvement in BD.

Abstract
Behcet's Disease (BD) is a systemic vasculitis of unknown etiology. Increasing studies find that a sophisticated interlacing cytokine network is closely implicated in the onset, evolution and even organ damages of the disease. Cytokines involved can be categorized as Th1 type, Th2 type, Th17 type, chemokines and other proinflammatory cytokines, etc. The vicious cycle of cytokine network plays a substantial role in the disease pathogenesis and even in organ lesions, and might be disorganized by blocking one of the key links of the cytokines, which in turn may provide essential clues to outlook the target therapy regimen of cytokine agents in BD. There have been a number of case reports of the positive efficacies of cytokine (and cytokine blocker) agents including Infiximab (Human murine chimeric Anti-TNF α monoclonal antibody), Anakinra (recombinant, non-glycosylated human IL1 receptor antagonist) etc in BD. IFN-α had been used clinically in treating BD with uveitis with beneficial efficacy ever since the 1980s. The studies to date suggested that IL6, IP10 are involved in BD with nervous system lesions, IL17, IL18 are relevant to the superimposed uveitis in patients with BD. Some cytokines i.e. IL8, RANTES, MIP-1α are associated with the disease activity, whereas others are exemplified by that of IL10, whose level shows negative relevance to the disease activity, might be potentially cytokine of protecting effect. According to the related genetic study, the SNPs of numerous cytokines including IL1, TNFα, IFNγ, IL12, and IL18 are pertinent to BD. The recent GWAS (Genome Wide Association Studies) demonstrated that SNPs in the IL10 and IL23R-IL12RB2 region are associated with the disease. Most studies nowadays are confined within the cytokines in the peripheral blood levels, owing to the potentially significant roles of certain cytokines in local lesions. It warrants further in-depth study to address this issue. Moreover, it deserves multi-centre study considering the unique geographical "silk road" display picture of the disease.

Abstract
AIM Increased frequency of cardiovascular disease and its possible relations with insulin resistance have been reported in patients with inflammatory diseases. The aim of our study was to investigate insulin resistance and serum adiponectin levels as cardiovascular risk markers in patients with Behçet's disease. METHOD Study population consisted of 40 patients with Behçet's disease (BD) and a control group composed of age, gender, body mass index-matched 46 healthy individuals. All patients were examined for signs of Behçet's disease. Body mass index, waist and hip circumference were measured. Insulin resistance was evaluated using the homeostasis model assessment-insulin resistance method. Erythrocyte sedimentation rate (ESR), lipid profile, high sensitive CRP (hsCRP), adiponectin, TNF-α, IL-6 and IL-8 levels were measured. RESULTS Erythrocyte sedimentation rate, serum hsCRP and IL-6 levels were significantly higher in patients with BD than those in the controls (P=0.001, P=0.001, P=0.001, respectively). Fasting plasma glucose, insulin levels and lipid profile were not different between the two groups. Insulin resistance and decreased levels of the serum adiponectin were not detected in the patients. There was no relationship between insulin resistance, adiponectin levels and inflammatory markers. Active and inactive patients did not differ in respect of any parameters. CONCLUSION Being a systemic vasculitis, BD may cause cardiovascular involvement. In this study, dyslipidemia, insulin resistance and low adiponectin levels were not detected among our patients with Behçet's disease. Our results suggest that there exists no increased risk for atherosclerotic cardiovascular disease associated with adiponectin levels and insulin resistance in patients with Behçet's disease.

Abstract
BACKGROUND To investigate plasma IL-17 level and the expression of Th17 cell transcription factor RORγt in the pathogenesis of Behçet's Disease (BD). MATERIAL/METHODS Blood samples were collected from 73 patients with BD (45 patients were in active stage), 20 systemic lupus erythematosus (SLE) and 12 multiple sclerosis patients (MS). Twelve patients with BD were investigated both in their active and remission stages. Samples were processed to detect IL-17A level in plasma by enzyme-linked immunosorbent assay (ELISA). Related gene expression was assessed by real-time reverse transcription polymerase chain reaction. Function of Th17 cells in active BD patients with erythema nodosum (EN)-like eruption was studied in relation to human umbilical vein endothelial cells (HUVECs). RESULTS We demonstrated the presence of Th17 cells and RORγt among the peripheral blood mononuclear cells (PBMC). The percentage of circulating Th17 cells and the ability to produce interleukin-17A (IL-17A) were increased in samples derived from patients with active BD, MS and SLE patients. We observed that IL-17A from patients with active BD could induce adhesion molecule messenger RNA expression in HUVECs. CONCLUSIONS RORγt determined Th17 cell might be involved with increased IL-17A in BD. Our results indicate that IL-17 contributes to the active proinflammatory pattern that is characteristic of inflammatory diseases and patients with active BD.

Abstract
Sudden sensorineural hearing loss (SSNHL) and Ménière's disease are the most common inner ear diseases in which the causes are unknown. As recent magnetic resonance imaging has demonstrated disruption of the blood-labyrinth barrier in these inner ear diseases, inflammatory reaction associated with increased permeability of the blood vessels may be involved. The genotypes of interleukin 1A (IL1A) (-889C/T; rs1800587) and interleukin 1B (IL1B) (-511C/T; rs16944) were determined using an allele-specific primer-polymerase chain reaction method in 72 patients with SSNHL, 68 patients with Ménière's disease, and 2202 control subjects living almost in the same area as the patients. A significantly higher prevalence of the IL1A-889T allele was observed in SSNHL and Ménière's disease compared with controls, although no significant difference in distribution of IL1B-511C/T genotypes was observed between the patients and controls. Adjusted odd ratios for SSNHL and Ménière's disease risks in the -889TT genotypes were 25.89 (95% confidence interval (CI) 12.19-54.98) and 18.20 (95% CI 7.80-42.46), respectively, after age and gender were taken as moderator variables. Our results suggested that IL1A is closely associated with susceptibility of SSNHL and Ménière's disease.

Abstract
OBJECTIVE To review the progress in the field of MHC-related genetic susceptibility to Behçet's disease (BD). METHOD Systematic review of the English literature between 1 January 1980 and 31 January 2010 using Medline. Case-control, population-based, observational cohort studies investigating the association between BD and HLA-B*51 subtypes, classical and non-classical HLA alleles and other HLA-related genes were selected. The geographical distribution of BD and these susceptibility genes was also taken into consideration. Case and familial case reports were excluded except for case series with more than two patients. RESULTS Ninety articles plus 17 obtained from other sources were included in the systematic review. We have found high evidence that a core component of genetic susceptibility to BD is within the MHC region being primarily related to an HLA-B*51 subtype: HLA-B*5101/B*510101. Moreover, HLA-A*26, HLA-B*15, HLA-B*5701 and TNF-α -1031C were independently associated with BD. Data suggest that other HLA (HLA-C, HLA-DR) and HLA-related [MHC Class I chain-related gene A (MIC-A), TNF-α] genes may play a role in BD co-susceptibility or pathogenesis. Finally, the distinctive geographical distribution of BD suggested an evolutionary selection of HLA-B*51 subtypes as the major susceptibility factors for BD. CONCLUSION Further studies must be addressed to clarify the functional relevance of the different genes found to be associated with disease susceptibility and the potential interactions between genes located within and outside the MHC region.

Abstract
Genetic factors, including cytokine gene polymorphisms, are potential contributors to the pathogenesis of the Graves' disease (GD). We attempted in this study to determine the association between GD and the following polymorphisms in the interleukin-1 (IL-1) family genes: IL-1alpha (-889C/T), IL-1ss (-511C/T), IL-1ss (+3962C/T), IL-1R (Pst-1 1970C/T) and IL-1RA (Mspa-I 11100C/T). We studied 107 patients with an established diagnosis of GD and 140 healthy controls. Cytokine typing was performed by the polymerase chain reaction with sequence-specific primers assay. Genotype distributions among patients were in Hardy-Weinberg equilibrium for all polymorphisms. The frequency of the IL-1alpha -889T allele was significantly higher in patients than in controls (51.9% vs. 31.6%, OR=2.33, 95% CI=1.61-3.38; p<0.0001). The IL-1RA Msp-I 11100C allele was significantly more frequent in patients than in controls (50.0% vs. 22.9%, OR=3.38, 95% CI=2.29-4.97, p<0.0001). No significant associations were found for other polymorphisms. Although the IL-1 family has well-known roles in GD pathogenesis, the contributions of their genetic variations to the disease are unclear. In this study, we documented a highly significant association between GD and polymorphism in IL-1alpha and IL-1RA genes. Further studies in other populations are necessary to confirm our results.

Abstract
BACKGROUND AND AIMS Polymorphisms in the tumor necrosis factor (TNF) gene at the locations -308, -238, -863, -857 and -1031 have been studied in various ethnic groups for possible association with Behçet's disease. The aim of this meta-analysis is to examine the association between polymorphism in the TNF gene at the locations -308, -238, -863, -857 and -1031 and Behçet's disease. METHODS A literature review was performed using MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials for original studies published in English up to October 31, 2009 and that examined the association of the TNF-alpha promoter polymorphisms with Behçet's disease. All pooled odds ratios (OR) were derived from random-effects model with its 95% confidence intervals (CI). We assessed statistical heterogeneity among studies using Cochrane Q test and by calculating I(2). The Cochrane collaboration's software program, RevMan 5 was used to prepare and complete this review. RESULTS The literature search resulted in 13 studies. Ten studies met the included criteria and thus were selected. Overall, -1031C (OR = 1.35, 95% CI = 1.09-1.68), -238A (OR = 1.51, 95% CI = 1.12-2.04) and -857T (OR = 0.76, 95% CI = 0.58-0.98) had a significant association with Behcet's disease. The pooled estimates for the other polymorphisms were not statistically significantly associated with Behcet's disease; -308A and -863A. CONCLUSIONS Behcet's disease was associated with the -1031C, -238A and the -857T promoter polymorphisms in various ethnic groups.

Abstract
Individual variability in skin reactivity and healing capacity after trauma are important clinical issues. The aims were to develop an in vivo, human wound model based on a standardised minimal skin injury and to demonstrate therapeutic effect of simple wound therapies in terms of morphological wound outcome with changes in skin blood perfusion as a quantified indicator of wound healing. In a series of experiments, wounds were induced on the normal forearm skin of volunteers using a blood collection lancet. This was well tolerated. Wounds were assessed by naked eye examination or laser Doppler perfusion imaging (LDPI) at baseline and at up to 6 further time points up to 96 h in control wounds and wounds treated by commonly used occlusive dressing options. Assessment by clinical observation with 10x magnification showed over 96 h a progression of erythema, surface crust, a new keratinisation layer and finally healed areas. LDPI quantifying wound erythema showed a peak at 24 h and near normal levels at 96 h. Inter-individual variability was evident but intra-individual variability was much less pronounced. Wounds treated with occlusion showed a statistically significant more rapid return to baseline blood perfusion as measured by LDPI compared to controls supported by favourable healing parameters in the clinical assessment. The paper exemplifies use of non-invasive, bioengineering technique for quantification of individual innate variability in skin reactivity, wound healing capacity and therapeutic effect in a well-tolerated in vivo, human, minimal skin trauma model.

Abstract
Pathergy is the term used to describe hyper-reactivity of the skin that occurs in response to minimal trauma. A positive skin pathergy test (SPT), characterised by erythematous induration at the site of the needle stick with a small pustule containing sterile pus at its centre, is among the criteria required for a diagnosis of Behçet's disease (BD) and in certain population has been shown to be highly specific for this condition. Problems with standardising the induction manoeuvre for the SPT as well as the method of assessment of the response have limited the usefulness of the SPT in the clinical setting. Extensive investigation into histopathological and immunological aspects of pathergy has led to a number of hypotheses relating to the aetiology of the skin pathergy reaction and the disease itself, but the cause is considered to be unknown. Pathergy lesions, the development of new skin lesions or the aggravation of existing ones following trivial trauma, are also reported in pyoderma gangrenosum and has been noted in other neutrophilic dermatoses such as Sweet's syndrome. The response of such patient groups to the systematic application of the SPT has not been described. We propose that a new way of considering the pathergy reaction is to see it as an aberration of the skin's innate reactivity from a homeostatic reactive mode closely coupled to tissue healing to an abnormal destructive/inflammatory mode. Our understanding of BD and other similar conditions would profit by more detailed mechanistic knowledge of skin homeostasis to minimal trauma in both health and disease through a more structured and systematic use of the SPT.

Abstract
PURPOSE Interleukin-1 (IL-1) is known to have an important role in pathogenesis of Graves' ophthalmopathy (GO). Polymorphisms in IL-1 gene have been associated with autoimmune reactions. This study aimed to investigate the association of GO with single-nucleotide polymorphisms (SNPs) in the IL-1 family (IL-1alpha, IL-1beta, IL-1 receptor [IL-1R] and IL-1 receptor antagonist [IL-1RA]). METHODS A total of 57 patients of Graves' disease without GO, 50 patients with GO and 140 healthy controls were enrolled. Patients were recruited consecutively from the outpatient endocrine clinic of a large university general hospital. Cytokine typing was performed by the polymerase chain reaction with sequence-specific primers assay. The allele and genotype frequencies of the following polymorphisms were determined: IL-1alpha (-889C/T), IL-1beta (-511C/T), IL-1beta (+3962C/T), IL-1R (Pst-1 1970C/T) and IL-1RA (Mspa-1 11100C/T). Genotype distributions among patients were in Hardy-Weinberg equilibrium for all polymorphisms. RESULTS Among the five SNPs studied, the frequencies of the T allele and the TT genotype of IL-1alpha (-889C/T) were significantly higher among patients with GO than those without GO (odds ratio [OR] = 2.16, 95% confidence interval [CI] = 1.25-3.74; P = 0.006 and 5.67, 95% CI = 1.66-49.34; P = 0.005, respectively). For IL-1RA (Mspa-1 11100C/T), the frequencies of the C allele and the CC genotype were significantly higher among patients with GO (OR = 2.31, 95% CI = 1.34-4.00; P = 0.004 and 6.73 95% CI = 1.94-23.36; P = 0.004, respectively; P < 0.01). No significant association was found for other SNPs. CONCLUSION This is the first study to show a positive correlation between polymorphisms in the IL-1alpha and IL-1RA genes and susceptibility to GO. These findings promote further research into genetic correlates of GO.

Abstract
Behçet's disease (BD) is a chronic systemic inflammatory disorder characterized by recurrent ocular symptoms, oral and genital ulcers, and skin lesions. The etiology of BD is still uncertain, but genetic and environmental factors likely both play an important role in BD development. In the present study, we investigated whether polymorphisms of Toll-like receptor 2 (TLR2), previously reported to recognize BD candidate antigens, are associated with BD. Two hundred Japanese patients with BD and 128 Japanese healthy controls were recruited. We genotyped five single-nucleotide polymorphisms (SNPs) in the TLR2 gene and assessed the allele/genotype diversity between cases and controls for all SNPs. No significant differences in the frequency of TLR2 alleles, genotypes, and haplotypes in the BD cases were detected compared with the controls. These data indicate that TLR2 polymorphisms do not play an important role in the development of BD.

Abstract
Genetic factors predispose individuals to Behçet's disease (BD) and periodontal disease. IL-1 has been implicated in the pathogenesis of both BD and periodontal disease. The relationship between periodontitis and pathogenesis of BD has not yet been determined. Since IL-1 has been implicated in the pathogenesis of both BD and periodontal disease, we aimed to investigate the possible relation of the periodontal scores and SNPs of IL-1alpha-889C/T, IL-1beta-511C/T, and IL-1beta+3962T/C with BD compared to healthy controls (HC) and recurrent aphtous stomatitis (RAS). A total of 155 Turkish individuals were enrolled in this study. The periodontal status of all subjects was evaluated according to the WHO community periodontal index of treatment needs. For genotyping, CTS-PCR-SSP was employed. IL-1alpha-889C allele was significantly higher in BD patients (p = 0.03) and RAS (p = 0.02) compared to HC. The frequency of IL-1beta+3962T allele was significantly higher in RAS patients compared to HC (p = 0.015). Male gender (p = 0.04), age (p = 0.02) and carrying IL-1beta-511T allele (p = 0.01) were found to be a significant risk factors for higher periodontal scores in Turkish population. We can speculate that susceptibility to the development of periodontal disease could be influenced by IL-1 SNPs. Periodontitis-induced autoinflammatory response also may play a role in the development/severity of BD and RAS via IL-1 gene alteration.
