Sahinkaya S, Yilmaz M, Yay E, Toygar H, Balci N, Altinisik DD, Kutlubay Z, Kantarci A. Behçet's disease modifies the gingival inflammatory response. J Periodontol 2024. [PMID: 39295442 DOI: 10.1002/jper.24-0182] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2024] [Revised: 07/16/2024] [Accepted: 07/16/2024] [Indexed: 09/21/2024]
Abstract
BACKGROUND Behçet's disease (BD) pathogenesis involves severe outcomes such as blindness, central nervous system manifestations, and deep venous thrombosis that impacts systemic and local inflammatory changes. We tested the hypothesis that BD negatively affects gingival health and increases the severity of gingivitis. METHODS The study included 37 BD patients with gingivitis without any sign of periodontitis. Systemically healthy 19 patients with gingivitis (G) and 20 periodontally and systemically healthy individuals (C) were recruited as controls. BD patients were further grouped as stable and unstable based on their responses to BD treatment. Clinical periodontal parameters were measured to determine the impact of BD on gingival health. Serum and saliva levels of ELA-2 (neutrophil elastase-2), SLPI (secretory leukocyte protease inhibitor), α1-AT (alpha1-anti-trypsin), VEGF (vascular endothelial growth factor), IL-6 (interleukin-6), IL-8 (interleukin-8), and TNF-α (tumor necrosis factor alpha) were analyzed using multiplex immunoassay to measure the systemic and local inflammatory impact of BD. RESULTS Plaque index (PI), probing pocket depth (PPD), and bleeding on probing (BOP) were significantly higher in the BD group than in the controls (p < 0.05). IL-6 was higher in both serum and saliva in the BD group than in the G group (p < 0.05). ELA-2 levels in saliva were higher in the stable BD group than in the controls, while TNF-α and SLPI were statistically significantly higher in BD than in the control (p < 0.05). Salivary α1-AT level was statistically lower in the BD group compared to the control group. CONCLUSION Our study suggested that the gingival inflammatory profile was impaired in patients with BD.

İçen Taşkın I, Gürbüz S, Koç A, Kocabay S, Yolbaş S, Keser MF. The roles of SFKs in the regulation of proinflammatory cytokines and NLRP3 in familial mediterranean fever patients. Cytokine 2024; 179:156615. [PMID: 38640560 DOI: 10.1016/j.cyto.2024.156615] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 04/02/2024] [Accepted: 04/09/2024] [Indexed: 04/21/2024]
Abstract
Familial Mediterranean Fever (FMF) is caused by mutations in pyrin, a protein produced in innate immune cells that regulates the development of interleukin (IL)-1β by interacting with caspase-1 and other components of inflammasomes. Although overexpression of proinflammatory cytokines have been observed in FMF patients, no studies have been conducted on the role of Src family kinases (SFKs). The purpose of this study was to examine the impact of SFKs on the modulation of IL-1β, IL-6, IL-8, TNF-α, and NLRP3 inflammasome in patients with FMF. The study included 20 FMF patients and 20 controls. Peripheral blood mononuclear cells (PBMCs) were isolated by density gradient centrifugation. Protein expression levels of SFKs members were measured by western blot. The effect of lipopolysaccharide-induced (LPS) activation and PP2- induced inhibition of SFKs on NLRP3 and IL-1β, IL 6, IL-8, TNF-α were examined by western blot and flow cytometry respectively. Patients with FMF have considerably greater levels of Lck expression. In addition, patients had a substantially greater basal level of NLRP3 than the control group (*p = 0.016). Most importantly, the levels of IL-1 β were elevated with LPS stimulation and reduced with PP2 inhibition in FMF patients. These results suggest that SFKs are effective in regulation of IL-1 β in FMF patients.

Systemic inflammatory autoimmune disease before allogeneic hematopoietic stem cell transplantation is a risk factor for death in patients with myelodysplastic syndrome or chronic myelomonocytic leukemia. Ann Hematol 2024; 103:2059-2072.

Abstract
Myelodysplastic syndrome (MDS) is well known to be complicated by systemic inflammatory autoimmune disease (SIADs). However, it remains unclear how the prognosis after allogenic hematopoietic stem cell transplantation (allo-HSCT) in patients with MDS is impacted by SIADs that occur before allo-HSCT. Therefore, we hypothesized that SIADs before allo-HSCT may be a risk factor for negative outcomes after allo-HSCT in patients with MDS. We conducted a single-center, retrospective, observational study of sixty-nine patients with MDS or chronic myelomonocytic leukemia who underwent their first allo-HCT. Fourteen of the patients had SIADs before allo-HSCT. In multivariate analysis, the presence of SIADs before allo-HSCT was an independent risk factor for overall survival (HR, 3.36, 95% confidence interval: 1.34-8.42, p = 0.009). Endothelial dysfunction syndrome was identified in five of 14 patients with SIADs who required immunosuppressive therapy or intensive chemotherapy, and notably, all patients with uncontrollable SIADs at allo-HSCT developed serious endothelial dysfunction syndrome and died in the early phase after allo-HSCT. The development of SIADs in the context of MDS is thought to reflect the degree of dysfunction of hematopoietic cells in MDS and suggests a higher risk of disease progression. In addition, MDS patients with SIADs before allo-HSCT are considered to be at higher risk of endothelial dysfunction syndrome because of preexisting vascular endothelial dysfunction due to SIADs. In conclusion, SIADs before allo-HSCT constitute an independent risk factor for death in MDS patients undergoing allo-HSCT.

Abstract
Behçet's disease (BD) is a chronic, multi-systemic disorder of unknown aetiology typified by recurrent oral and genital mucocutaneous lesions, uveitis and vasculitis. Innate and adaptive immune system dysregulation has been implicated in pathogenesis with alterations in serum cytokine profiles. Few studies have investigated salivary cytokines in BD, despite more than 90% of BD patients first presenting with oral ulceration. The aim of this pilot study was twofold; firstly to investigate whether cytokine levels in matched serum and saliva samples show a differential profile in BD (with and without oral ulcers), recurrent aphthous stomatitis (RAS) and healthy controls (HCs), and secondly, to explore if any differential profiles in serum and/or saliva could provide a panel of cytokines with diagnostic and therapeutic potential for BD. Concentrations of 12 cytokines (IL-1β, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70, IL-17A, IFN-γ, TNF-α, TNF-β) were measured using the Human Th1/Th2 11-Plex FlowCytomix™ kit with IL-17A, in BD (N=20), RAS (N=6) and HCs (N=10). A differential range of cytokines was detected in serum and saliva with the majority of cytokine levels higher in saliva. The most prevalent salivary cytokines were IL-1β, IL-2, IL-8, IL-10 and TNF-α present in all samples in contrast to serum where the most prevalent cytokine detected was IL-8 (91.9%). The least abundant cytokine was IFN-γ in both saliva (43.2%) and serum (2.7%). After normalizing saliva for protein content, BD patients with oral ulcers (BD-MA) had significantly higher levels of salivary IL-1β (p=0.01), IL-8 (p=0.02), TNF-α (p=0.004) and IL-6 (p=0.01) than HCs. Notably, BD patients without oral ulcers (BD-MQ) also had significantly higher salivary IL-1β, IL-8 and TNF-α (p ≤ 0.05) than HCs. During relapsed (BD-RE) and quiet (BD-Q) systemic episodes, salivary IL-β and TNF-α were also significantly increased with IL-8 significantly higher only in BD-Q (p=0.02). BD oral ulcers signify a potential reactivation of systemic inflammation. Identifying cytokines released during asymptomatic episodes and oral ulceration might lead to targeted drug therapy to prevent recurrent oral ulcers and possible disease relapse. This is the first study to report salivary cytokine levels in BD. The detectable levels suggests cytokine profiling of BD saliva may provide an alternative, less invasive, sensitive procedure for frequent monitoring of disease activity and progression.

Abstract
Interleukin (IL)-6 is a pleiotropic cytokine that is involved in the pathogenesis of various rheumatic diseases. Direct inhibition of the IL-6 pathway by an anti-IL-6 receptor or inhibiting the ligand itself has proved to be efficacious in the treatment of these diseases. Juvenile idiopathic arthritis, adult-onset Still's disease, large vessel vasculitis including giant cell arteritis and Takayasu disease, systemic sclerosis, and polymyalgia rheumatica respond well to IL-6 inhibition as expected. However, no clinically meaningful effect has been observed with regard to IL-6 blockade in ankylosing spondylitis, psoriatic arthritis, and systemic lupus erythematosus. This review discusses the current state of IL-6 targeting approaches in various rheumatic diseases other than rheumatoid arthritis.

Abstract
Interleukin 6 (IL-6) is a pro-inflammatory cytokine that stimulates acute phase responses, hematopoiesis and specific immune reactions. Recently, it was found that the IL-6 plays a vital role in the progression of COVID-19, which is responsible for the high mortality rate. In order to facilitate the scientific community to fight against COVID-19, we have developed a method for predicting IL-6 inducing peptides/epitopes. The models were trained and tested on experimentally validated 365 IL-6 inducing and 2991 non-inducing peptides extracted from the immune epitope database. Initially, 9149 features of each peptide were computed using Pfeature, which were reduced to 186 features using the SVC-L1 technique. These features were ranked based on their classification ability, and the top 10 features were used for developing prediction models. A wide range of machine learning techniques has been deployed to develop models. Random Forest-based model achieves a maximum AUROC of 0.84 and 0.83 on training and independent validation dataset, respectively. We have also identified IL-6 inducing peptides in different proteins of SARS-CoV-2, using our best models to design vaccine against COVID-19. A web server named as IL-6Pred and a standalone package has been developed for predicting, designing and screening of IL-6 inducing peptides (https://webs.iiitd.edu.in/raghava/il6pred/).

Abstract
Increasing evidence has suggested that T helper 17 (Th17) cells play a central role in the pathogenesis of ocular immune disease. The association between pathogenic Th17 cells and the development of uveitis has been confirmed in experimental and clinical studies. Several cytokines affect the initiation and stabilization of the differentiation of Th17 cells. Therefore, understanding the mechanism of related cytokines in the differentiation of Th17 cells is important for exploring the pathogenesis and the potential therapeutic targets of uveitis. This article briefly describes the structures, mechanisms, and targeted drugs of cytokines-including interleukin (IL)-6, transforming growth factor-β1 (TGF-β1), IL-1β, IL-23, IL-27, IL-35, IL-2, IL-4, IL-21, and interferon (IFN)-γ-which have an important influence on the differentiation of Th17 cells and discusses their potential as therapeutic targets for treating autoimmune uveitis.

Abstract
Aim:
To display microRNA155 (miRNA155) expression in different entities of Behçet’s disease (BD), and to find out if expression is affected in more than one of disease status than another, either phenotypically, according to HLA B51 expression, presence of family history, or patients’ age. Methods: Thirty BD patients (13 of which were HLAB51 positive) and 15 healthy subjects’ samples were obtained. White blood cell miRNA155 expression in both types of samples was estimated. Results: Results showed that there is a degree of relation between decrease of miRNA155 expression and different disease aspects, and also, that miRNA155 has an inverse relation with the patients’ ages. Conclusion: MiRNA155 might be used as a measure of disease of different phenotypes, and that any manifestation of the disease can happen when the expression level decreases.

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.

Abstract
Behçet’s disease (BD) affects multiple organs. It is mainly characterized by recurrent oral, skin, and genital aphthous ulcers, and eye involvement. Successful management of BD is increasing, although its etiology remains unclear. A number of etiologies have been proposed, including environmental, genetic, viral, and immunological factors. To understand its complex etiology and improve its management, animal models of BD have been used to enable more effective therapeutic applications with increased clinical significance. An herpes simplex virus (HSV) type 1-induced BD mouse model has shown disease characteristics similar to those seen in BD patients. An HSV-induced BD animal model has been used to test various therapeutic modalities. The applied modalities are several materials that are derived from natural products, conventional therapeutics, and possible biologics. In this review, we provided how they regulate inflammation in an HSV-induced BD model.

Abstract
Behcet's disease is a multisystemic vasculitis. Arterial involvement in the form of acute dissection is rare. A 42-year-old Lebanese man with Behcet's disease presented with severe abdominal pain. On exam, blood pressure was 162/104 mm Hg, and he exhibited epigastric tenderness. CT angiogram demonstrated an acute dissection of the coeliac artery trunk, common hepatic artery and proper hepatic arteries, with asymmetric thickening of the proximal left subclavian artery and circumferential thickening of the abdominal infrarenal aorta suggestive of vasculitis. Treatment included intravenous clevidipine, nitroprusside and methylprednisolone, which transitioned to oral metoprolol, amlodipine and prednisone. He responded well. Arterial dissections have been described with Behcet's. We report a coeliac artery aneurysm in association with a flare of Behcet's disease. Arterial wall inflammation combined with the sheering forces of hypertension likely predisposes to arterial dissection.

Abstract
BACKGROUND IL-6 mRNA expression is significantly high in many autoimmune diseases such as Behçet's disease; this is often related with more aggressive phenotypes. Nevertheless, the essential molecular process for its high expression has not been completely realized. The aim of this study was undertaken to estimate the gene copy number variation and promoter methylation to IL-6's high expression. METHODS This study was performed on 51 patients and 61 healthy controls. Initially, DNA and RNA were extracted from all specimens. Promoter methylation levels of IL-6 were evaluated by MeDIP-qPCR technique. Also, IL-6 gene expression was measured by Real-time PCR. After that, we evaluated the relationship between gene expression and methylation, as well as their relationship with clinical specification. RESULTS As we expected, the expression level of IL-6 gene increased significantly in the patient group compared to the healthy subjects. Also, the relative promoter methylation level of the IL-6 mRNA was significantly lower in patient group compared to healthy group (p<0.001). DISCUSSION We disclosed that the promoter hypomethylation may be considered as one of the main defects for IL-6 mRNA high expression in patients with Behçet's disease.

Abstract
Purpose Changes in concentrations of acute phase proteins in the serum of patients might be significant in the pathogenesis of Behçet disease. This report investigates the association between ocular disease activity and serum haptoglobin levels in patients with Behçet disease, and summarizes the current understanding of the correlation between acute phase proteins and Behçet disease based on both personal studies and data from the literature. Methods Thirty patients with Behçet disease with ocular involvement and 15 healthy subjects were included in the study. Of the 30 patients, 14 had acute uveitis and 16 had inactive ocular involvement at the time of enrollment. Results There was a significant difference in haptoglobin levels between the patients with active ocular disease and controls (p=0.0005). There was also a significant difference in haptoglobin levels between the patients with inactive ocular disease and control subjects (p<0.0001). However, no significant difference was observed among patients with active versus inactive uveitis with regard to serum haptoglobin levels. Conclusions Higher serum haptoglobin levels in patients with Behçet disease compared to control subjects were obtained. However, elevated serum haptoglobin levels do not seem to be a risk factor for uveitis activity. Behçet disease is generally diagnosed by physical examinations and no laboratory marker has been widely accepted for follow-up of disease activity.

Abstract
CD206 is a macrophage mannose receptor involved in variety of autoimmune and inflammatory diseases. This study aimed to identify the pathogenic role of CD206 in a herpes simplex virus (HSV) induced Behçet's disease (BD) mouse model. CD206 positive cells were detected in peripheral blood mononuclear cells and quantified by flow cytometry. Levels of cytokines were measured by ELISA. CD206 was found to be down-regulated both in vitro (10-6M) and in vivo (200μg/mouse) after treatment with N-acetylgalactosamine (GalNAc), a ligand for CD206. The down-regulation of CD206 was correlated with improvement in BD symptoms. Colchicine (2μg/mouse) or pentoxifylline (400μg/mouse) treated mice displayed improvement in BD symptoms with fewer CD206 positive cells. The prevalence of CD206-positive cells differed between ligand-responsive and non-responsive BD mice. Inhibition of CD206 was associated with down-regulated serum level of interleukin-17 in GalNAc-treated BD mice. These results suggest that the expression of CD206 is correlated with HSV-induced BD symptoms in mice, implicating that CD206 might have a pathogenic role in BD.

Abstract
Behçet's disease (BD) is a multi-systemic inflammatory disorder consisting of recurrent oral aphthosis, genital ulcers, and chronic relapsing bilateral uveitis; however, many other organs may be affected. Several pro-inflammatory cytokines, mainly derived from Th1 and Th17 lymphocytes, seem to be involved in different pathogenic pathways leading to development of the clinical manifestations. On this basis, the primary aim of our study was to compare a core set of pro-inflammatory cytokines between patients with BD and healthy control (HC). The secondary goal was to evaluate potential correlations between these putative circulating biomarkers, the status of disease activity, and the specific organ involvement at the time of sample collection. Fifty-four serum samples were collected from 46 BD patients (17 males, 29 females, mean age 45.5 ± 11.3 years), and 19 HC (10 males, 9 females, mean age 43 ± 8.3 years). Twenty-five serum cytokines (APRIL/TNFS13, BAFF/TNFSF13B, sCD30/TNFRSF8, sCD163, Chitinase3-like1, gp130/sIL-6Rb, IFNb, sIL-6Ra, IL-10, IL-11, IL-19, IL-20, IL-26, IL-27 (p28), IL-28A/IFN-lambda2, IL-29/IFN-lambda1, IL-32, IL-34, IL-35, LIGHT/TNFSF-14, Pentraxin-3, sTNF-R1, sTNF-R2, TSLP, and TWEAK/TNFSF-12) were simultaneously quantified using a Bio-Rad cytokine bead arrays. Serum concentration of sTNF-R1 (p < 0.01) and sTNF-R2 (p < 0.01) resulted higher in both active and inactive BD than HC, while Chitinase3-like1 (p < 0.05) and gp130/sIL-6Rb (p < 0.01) serum levels were significantly higher in inactive BD, and IL-26 (p < 0.01) in active BD than HC. No differences were observed between inactive and active BD group. In addition, we observed that gp130/sIL-6Rb, sIL-6Ra, IL-35, and TSLP serum levels were significantly enhanced in patients with mucocutaneous manifestations plus ocular involvement (MO-BD) compared to subgroup with only mucocutaneous involvement (M-BD). Our findings may suggest a signature of IL-6, tumor necrosis factor-α as well as of Th17 response in BD patients due to increased levels of gp130/sIL-6Rb, sTNF-R1, sTNF-R2, IL-26, respectively. This evidence could contribute to improve the knowledge regarding the role of these citokines in the induction of specific BD clinical features.

Abstract
Behçet's disease (BD) is a multisystemic chronic inflammatory disease characterized by relapsing oral and genital ulcers, uveitis, and skin lesions. The pathogenesis of BD is still unknown. Aberrant production of some cytokines/chemokines plays an important role in the pathogenesis of various inflammatory diseases. Revealing a key signaling regulatory mechanism involved in proinflammatory cytokines/chemokines production is critical for understanding of the pathogenesis of BD. The aim of this study was to determine the role of Src family kinases (SFKs) in production of some LPS-induced proinflammatory cytokines/chemokines in peripheral blood mononuclear cells (PBMC) of active BD patients. Chemical inhibition of SFKs activity impaired LPS-induced TNF-α production in PBMC of active BD patients, suggesting that modulating SFKs activity may be a potential target for BD treatment.

Abstract
BACKGROUND Serum YKL-40 is an inflammatory biomarker of endothelial dysfunction and may play a role in the inflammatory process of Behçet disease (BD). OBJECTIVES Serum YKL-40 levels were evaluated in patients with BD in order to identify associations with other inflammatory cytokines and establish laboratory parameters. Serum YKL-40 levels were also compared with BD clinical features and disease activity. METHODS In total, 112 patients with BD and 45 age- and sex-matched healthy volunteers were included. Disease activity was assessed with BD Current Activity Form score and Electronic Medical Record-based Activity Index (EMRAI) score. RESULTS Serum YKL-40 levels were significantly higher in patients with BD (median 41·88, range 12·52-171·30 ng mL(-1) ) than in healthy volunteers (median 20·92, range 5·01-64·20 ng mL(-1) ; P < 0·01). The cut-off value for YKL-40 (30·005 ng mL(-1) ) was determined from the receiver operating characteristic curve. EMRAI scores and the proportion of patients in the active phase of BD presenting with two or more major criteria were significantly higher in patients with elevated YKL-40 levels (P = 0·04 and P = 0·04, respectively). A statistically significant elevation in YKL-40 levels was observed in patients with active BD compared with patients with inactive BD (P = 0·05). Serum YKL-40 values were positively correlated with interleukin-6 and EMRAI scores (both P = 0·04), indicating that serum YKL-40 levels are increased in patients with BD and positively correlate with disease activity. CONCLUSIONS YKL-40 may play a role in the pathophysiology of BD and provide a useful marker for monitoring patients with BD.

Abstract
Behcet's disease (BD) is a multisystemic disorder of unknown etiology characterized by relapsing oral-genital ulcers, uveitis, and involvement of vascular, gastrointestinal, neurological, and musculoskeletal system. Although disease pathogenesis is still unclear, both innate and adaptive immunity have shown to play a pivotal role, and multiple proinflammatory cytokines seem to be involved in different pathogenic pathways that eventually lead to tissue damage.The aims of our study were to evaluate serum cytokines levels of IL-8, IL-18, IFN-α2a, IL-6, IFN-γ, CXCL10, CXCL11, CXCL9, and SAA levels in patients with BD, in comparison to healthy controls (HC), and to correlate their levels to disease activity.We included 78 serum samples obtained from 58 BD patients and analyzed a set of proinflammatory cytokines including IL-8, IL-18, IFN-α2a, IL-6, IFN-γ, CXCL10, CXCL11, and CXCL9 by multiplex bead analysis as well as SAA by enzyme-linked immunosorbent assay.Compared to HC, BD patients showed elevated cytokine levels of IL-8, IL-18, IFN-α2a, and IL-6, and low levels of CXCL11. BD patients with SAA serum levels >20 mg/L showed higher levels of proinflammatory markers than HC or group with SAA ≤20 mg/L. IL-18, IFN-α2a, and IL-6 were higher in BD group with SAA >20 mg/L than HC, while IL-8 and CXCL9 levels were higher than in patients with SAA ≤20 mg/L and HC.Active BD patients with SAA >20 mg/L exhibited elevated levels of inflammatory mediators, suggesting that may exist a relationship between SAA and proinflammatory cytokines in the intricate scenario of BD pathogenesis.

Abstract
Interleukin 6 (IL-6) is a major pro-inflammatory cytokine and dysregulation of IL-6 is relevant to many inflammatory diseases. Endotoxin induced tolerance of IL-6 is an important mechanism to avoid the excessive immune reaction. But to date, the molecular mechanisms of endotoxin tolerance of IL-6 remain unclear. Here we reported that IL-6 secretion and microRNA-181b (miR-181b) expression were inversely correlated following LPS stimulation. We also demonstrated that miR-181b targeting the 3′-UTR of IL-6 transcripts and up-regulation of miR-181b was associated with NF-kB. We further demonstrated that up-regulation of miR-181b in response to LPS was required for inducing IL-6 tolerance in macrophage. Our results suggested that the post-transcriptional control mediated by miR-181b could be involved in fine tuning the critical level of IL-6 expression in endotoxin tolerance.

Abstract
The interleukin-6 (IL-6) is a pleiotropic cytokine that plays a key role in interaction between immune and nervous system. Although IL-6 has neurotrophic properties and beneficial effects in the CNS, its overexpression is generally detrimental, adding to the pathophysiology associated with CNS disorders. The source of the increase in peripheral IL-6 remains to be established and varies among different pathologies, but has been found to be associated with cognitive dysfunction in several pathologies. This comprehensive review provides an update summary of the studies performed in humans concerning the role of central and peripheral IL-6 in cognitive dysfunction in dementias and in other systemic diseases accompained by cognitive dysfuction such as cardiovascular, liver disease, Behçet's disease and systemic lupus erythematosus. Further research is needed to correlate specific deficits in IL-6 and its receptors in pathologies characterized by cognitive dysfunction and to understand how systemic IL-6 affects high cerebral function in order to open new directions in pharmacological treatments that modulate IL-6 signalling.

Abstract
Cytokines play critical roles in the pathogenesis of Behçet's disease (BD). They mediated many of the effectors and regulatory functions of immune and inflammatory responses. Many studies have linked Interleukin-6 (IL-6) and Interleukin-10 (IL-10) pathologically to BD. Thus, this study aimed to investigate the associations between IL-6 and IL-10 promoter single-nucleotide polymorphisms (SNPs) and the susceptibility to BD and their implication on plasma levels. We genotyped IL-6 -174 G/C (rs1800795) using Mutagenically Separated Polymerase Chain Reaction PCR (MS-PCR) and IL-10 -1082 G/A (rs1800896) and -819 C/T (rs1800871) using Sequence Specific Primer PCR (SSP-PCR) in 87 Egyptian patients and 97 controls. The plasma levels of IL-6 and IL-10 were measured using Enzyme-linked Immunosorbent Assay (ELISA). Significant increase in the frequency of -1082 GG genotype (P<0.05, OR=2.25, 95%CI=1.03-4.91) and significant decrease in the frequency of -1082 GA genotype (P<0.05, OR=0.53, 95%CI=0.29-0.96) was demonstrated in BD patients compare to controls. Patients with genital ulcer had significantly lower frequency of -1082 GG (P<0.05, OR 0.2, 95% CI=0.04-0.99) and G allele (P<0.05, OR=0.28, 95%CI=0.08-0.93), while patients with ocular manifestations had significantly higher frequency of -1082 G allele (P<0.01, OR=2.28, 95%CI=1.19-4.36). BD patients had significantly higher level of IL-6 (P<0.001) and significantly lower level of IL-10 (P<0.001) compared to controls. The changes in the level of cytokines were independent of any genotype of IL-6 or any genotype/haplotype of IL-10. Patients with active disease state had significantly higher level of IL-6 compared to patients in remission (P<0.05). In conclusion, our preliminary study indicates that the polymorphism at IL-10 -1082 G/A may play a role in BD susceptibility. The significant increase in IL-6 level and the significant decrease in IL-10 level in BD patients were independent of any particular genotype in IL-6 or any particular genotype/haplotype in IL-10.

Abstract
Neuro-Behçet’s disease (NBD) is one of the more serious manifestations of Behçet’s disease (BD), which is a relapsing inflammatory multisystem disease with an interesting epidemiology. Though NBD is relatively uncommon, being potentially treatable, neurologists need to consider it in the differential diagnosis of inflammatory, infective, or demyelinating CNS disorders. Evidence-based information on key issues of NBD diagnosis and management is scarce, and planning for such studies is challenging. We therefore initiated this project to develop expert consensus recommendations that might be helpful to neurologists and other clinicians, created through an extensive literature review and wide consultations with an international advisory panel, followed by a Delphi exercise. We agreed on consensus criteria for the diagnosis of NBD with two levels of certainty in addition to recommendations on when to consider NBD in a neurological patient, and on the use of various paraclinical tests. The management recommendations included treatment of the parenchymal NBD and cerebral venous thrombosis, the use of disease modifying therapies, prognostic factors, outcome measures, and headache in BD. Future studies are needed to validate the proposed criteria and provide evidence-based treatments.

Abstract
In the past decade, tocilizumab, an anti interleukin-6 agent, has been successfully developed as a therapeutic agent for the treatment of rheumatoid arthritis and systemic onset juvenile idiopathic arthritis. In addition to countering inflammation, tocilizumab is also known affect B cell as well as T cell function, thus modulating immune function, and impact osteoclasts, as well as vascular endothelial growth factor. As such, its efficacy is currently being explored in a large number of autoiommune conditions including a number of vasculitides, systemic lupus erythematosus, systemic sclerosis, polymyositis, graft versus host disease, relapsing polychondritis, as well as Behcet's syndrome, spondyloarthropathies, and tumor necrosis factor receptor associated periodic syndrome.

Abstract
Interleukin-6 (IL-6), produced by a variety of cells, is a typical cytokine featuring redundancy and pleiotropic activity. IL-6 is promptly and transiently synthesized in response to infections or injuries, and participates in host defense by inducing immune responses, hematopoiesis, and acute-phase reactions. However, since its abnormal persistent production of mostly unknown etiology plays an important pathological role in the development of various immune-mediated diseases, a humanized anti-IL-6 receptor monoclonal antibody, tocilizumab, was developed and is now used as an innovative biologic for rheumatoid arthritis in more than 90 countries. Several factors strongly suggest that a IL-6 blockade strategy may have a broad application for the treatment of various immune-mediated diseases. These factors include favorable results of pilot or case studies with off-label use of tocilizumab, pathological analyses of the contribution of IL-6 to the development of immune-mediated diseases, and the potential capability of tocilizumab to both repair an imbalance of effector T cell subsets and to suppress pathologic autoantibody production. However, clinical trials to evaluate the efficacy and safety of tocilizumab for these diseases are essential. Furthermore, clarification of the cell source of IL-6 production and of the mechanisms through which dysregulated continuous IL-6 synthesis is induced constitutes an important issue for future studies into the pathogenesis of diseases.

Abstract
BACKGROUND Mucocutaneous type of Behcet's disease (MCBD) is a multisystemic inflammatory disease with oral and genital ulcers with or without skin lesions. METHODS A solid phase, two-site sequential chemiluminescent immunometric assay was used to measure serum levels of interleukin (IL)-6, IL-8 and tumour necrosis factor (TNF)-alpha in 54 normal control subjects and in 64 MCBD patients before and after treatment with levamisole plus colchicine. RESULTS We found that 67%, 83% or 67% of MCBD patients had a serum IL-6, IL-8 or TNF-alpha level greater than the upper normal limit of 4.7, 8.7 or 7.4 pg/ml, respectively. The mean serum level of IL-6 (9.9 +/- 2.4 pg/ml, P < 0.005), IL-8 (107.5 +/- 21.4 pg/ml, P < 0.001) or TNF-alpha (22.5 +/- 4.1 pg/ml, P < 0.001) in 64 MCBD patients was significantly higher than that (2.1 +/- 0.2, 5.7 +/- 0.2 or 3.8 +/- 0.2 pg/ml for IL-6, IL-8 or TNF-alpha level, respectively) in normal control subjects. In 43 MCBD patients with all the serum IL-6, IL-8 and TNF-alpha levels higher than their upper normal limits, treatment with levamisole plus colchicine for a period of 0.5-11.5 (mean, 3.2 +/- 2.4) months could significantly reduce the mean serum IL-6, IL-8 and TNF-alpha levels from 9.0 +/- 1.7 to 1.6 +/- 0.2 pg/ml (P < 0.001), 134.6 +/-28.2-6.0 +/- 0.4 pg/ml (P < 0.001) and 25.7 +/- 5.6-3.5 +/- 0.4 pg/ml (P < 0.001), respectively. CONCLUSIONS Treatment with levamisole and colchicine can result in a significant reduction of serum IL-6, IL-8 or TNF-alpha level in MCBD patients.

Abstract
Isotretinoin-induced keloid formation has occasionally been reported in patients who have undergone dermabrasion or laser treatment. This report describes a man with Behçet's disease (BD) who was prescribed isotretinoin for nodulocystic acne. After approximately 8 weeks of this treatment, the patient developed extensive keloids. There are no previous reports of possible isotretinoin-induced keloid formation in the setting of BD. This article discusses possible connections between BD, keloid formation and isotretinoin, which may be manifested in this case.

Abstract
The aim of this work was to study the effects and side effects of gemcitabine (2',2'-difluorodeoxycytidine, dFdC), a pyrimidine synthesis inhibitor, on skin lesions of a herpes simplex virus (HSV)-induced Adamantiades-Behçet's disease (ABD)-like mouse model. For the dose-escalation study, ICR mice were treated intraperitoneally with dFdC over 5 days. For the efficacy study, ICR mice were inoculated with HSV and classified as having ABD according to a revised Japanese classification, and then 18 ABD mice were randomly assigned to placebo, 0.06 or 0.12 microg of dFdC/day over 5 days. Serum levels of interleukin-4 (IL-4), IL-6, IL-10, interferon-gamma (IFN-gamma), and tumor necrosis factor-alpha (TNF-alpha) were determined using enzyme-linked immunosorbent assay. After application of 3 microg of dFdC over 5 days, alanine aminotransferase increased (P = 0.032), but all other kidney and liver parameters were unchanged. In ABD mice, 5 days of dFdC treatment with 0.06 or 0.12 microg of dFdC/day resulted in a dose-dependent improvement of cutaneous manifestations by more than 60% (P = 0.017). There was no significant change in cytokine levels, and none of the cytokine levels correlated with response to treatment. Moreover, dFdC shows promising effects to improve cutaneous lesions in the HSV-induced ABD-like mouse model. In this animal model, effects of dFdC on the cytokine profile remained inconclusive.

Abstract
OBJECTIVE To investigate a possible pathogenic role of cytokines in Behçet's disease (BD) by focusing on the analysis of cytokine gene expression within mucocutaneous BD lesions. METHODS The study group comprised 20 patients with active BD. In this group, a set of chemokines as well as Th1 and Th2 cytokines in biopsy specimens obtained from oral and genital ulcers, pseudofolliculitis lesions, and lesions at the site of pathergy testing were studied using real-time quantitative reverse transcriptase-polymerase chain reaction. RESULTS We observed important increases in the expression of interleukin-8 (IL-8) ( approximately 700-fold), monocyte chemoattractant protein 1 ( approximately 65-fold), interferon-gamma ( approximately 71-fold), and IL-12 ( approximately 69-fold) messenger RNA in BD lesions compared with normal skin. Except for IL-10 ( approximately 75-fold increase), Th2 cytokines (i.e., IL-4 and IL-13) were absent. CONCLUSION Our data suggest a direct role of Th1 lymphocytes in the pathogenesis of mucocutaneous BD lesions.

Abstract
BACKGROUND Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and cytokines, including serum interleukin (IL)-6, IL-8 and IL-10, and tumour necrosis factor-alpha (TNF-alpha) have been proposed as disease activity markers in Behçet's disease (BD), although studies have shown conflicting results for IL-6. Serum procalcitonin (PCT) levels in active BD have not yet been investigated. OBJECTIVE The aim of the present study was to determine the reliability of serum IL-6 and PCT levels as well as CRP as biological markers for activity of BD. METHODS Serum PCT, IL-6 and CRP protein levels were measured in patients with active BD (n = 15) and in healthy control subjects (n = 15). IL-6 and PCT levels were measured in serum by chemiluminescent assay. In addition, a nephelometric method was used to analyse CRP concentrations in serum. RESULTS Serum CRP and IL-6 values were significantly higher in the subjects with active disease than in the healthy controls (P < 0.05), but there was no significant difference in the levels of PCT in the two groups. CONCLUSION The results of our study suggest that serum CRP and IL-6 levels are elevated in patients with active BD, but that serum PCT values are not elevated in these patients.

Abstract
Plant medications have been used as treatment in various kinds of systemic inflammatory disorder such as Behçet's disease (BD). We investigated the roles of On-Chung-Eum (OCE), a traditional plant medicine, in cytokine regulation of BD. The effects of OCE on cytokine production from phytohaemagglutinin (PHA)-stimulated peripheral blood mononuclear cells (PBMC) of Behçet's patients and control subjects were measured by ELISA. PBMC from patients with active BD produced higher levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) compared to control. OCE significantly inhibited the production of TNF-alpha, IL-1beta and interferon-gamma (INF-gamma), compared to absence of OCE. The inhibitory effects of OCE showed in a dose-dependent manner, and OCE had better effects than immunosuppressive drug, cyclosporin A. OCE is able to effectively inhibit proinflammatory cytokines and immunoregulatory Th1 cytokine. OCE treatment for BD patients may help the improvement of symptoms through cytokine modulation.
