Abstract
INTRODUCTION This study aims to characterize ocular manifestations of juvenile Behçet's disease (jBD). METHODS This was a registry-based observational prospective study. All subjects with jBD from the Autoinflammatory Diseases Alliance (AIDA) Network BD Registry showing ocular manifestations before 18 years were enrolled. RESULTS We included 27 of 1000 subjects enrolled in the registry (66.7% male patients, 45 affected eyes). The median (interquartile range [IQR]) age at ocular involvement was 14.2 (4.7) years. Uveitis affected 91.1% of eyes (anterior 11.1%, posterior 40.0%, panuveitis 40.0%), retinal vasculitis 37.8% and other manifestations 19.8%. Later onset (p = 0.01) and male predominance (p = 0.04) characterized posterior involvement. Ocular complications occurred in 51.1% of eyes. Patients with complications had earlier onset (p < 0.01), more relapses (p = 0.02) and more prolonged steroidal treatment (p = 0.02). The mean (standard deviation [SD]) central macular thickness (CMT) at the enrolment and last visit was 302.2 (58.4) and 293.3 (78.2) μm, respectively. Fluorescein angiography was pathological in 63.2% of procedures, with a mean (SD) Angiography Scoring for Uveitis Working Group (ASUWOG) of 17.9 (15.5). At the last visit, ocular damage according to the BD Overall Damage Index (BODI) was documented in 73.3% of eyes. The final mean (SD) best corrected visual acuity (BCVA) logMAR was 0.17 (0.47) and blindness (BCVA logMAR < 1.00 or central visual field ≤ 10°) occurred in 15.6% of eyes. At multivariate regression analysis, human leukocyte antigen (HLA)-B51 + independently predicted a + 0.35 change in the final BCVA logMAR (p = 0.01), while a higher BCVA logMAR at the first assessment (odds ratio [OR] 5.80; p = 0.02) independently predicted blindness. CONCLUSIONS The results of this study may be leveraged to guide clinical practice and future research on this rare sight-threatening condition.

[PMID: 38003572 PMCID: PMC10671634 DOI: 10.3390/ijms242216382] [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: 09/28/2023] [Revised: 11/04/2023] [Accepted: 11/10/2023] [Indexed: 11/26/2023] Open
Abstract
Behçet's disease (BD) is a complex, recurring inflammatory disorder with autoinflammatory and autoimmune components. This comprehensive review aims to explore BD's pathogenesis, focusing on established genetic factors. Studies reveal that HLA-B*51 is the primary genetic risk factor, but non-HLA genes (ERAP1, IL-10, IL23R/IL-12RB2), as well as innate immunity genes (FUT2, MICA, TLRs), also contribute. Genome-wide studies emphasize the significance of ERAP1 and HLA-I epistasis. These variants influence antigen presentation, enzymatic activity, and HLA-I peptidomes, potentially leading to distinct autoimmune responses. We conducted a systematic review of the literature to identify studies exploring the association between HLA-B*51 and BD and further highlighted the roles of innate and adaptive immunity in BD. Dysregulations in Th1/Th2 and Th17/Th1 ratios, heightened clonal cytotoxic (CD8+) T cells, and reduced T regulatory cells characterize BD's complex immune responses. Various immune cell types (neutrophils, γδ T cells, natural killer cells) further contribute by releasing cytokines (IL-17, IL-8, GM-CSF) that enhance neutrophil activation and mediate interactions between innate and adaptive immunity. In summary, this review advances our understanding of BD pathogenesis while acknowledging the research limitations. Further exploration of genetic interactions, immune dysregulation, and immune cell roles is crucial. Future studies may unveil novel diagnostic and therapeutic strategies, offering improved management for this complex disease.

Abstract
PURPOSE This review aims to provide better understanding of modern modalities to investigate ocular symptoms of Behçet's disease in order to achieve appropriate management protocols and reduce irreversible visual loss. RELEVANT FINDINGS Current methods of diagnosing intraocular involvement in Behçet's disease gives clue to early diagnosis. In addition to standard ocular examination and fluorescein angiography, new noninvasive methods include ocular coherence tomography (OCT) and OCT angiography provide early detection of macular and retinal involvement that can be treated early to improve the prognosis. SUMMARY Over the last decade, new multimodal imagings are becoming more accessible; therefore, rapid diagnosis can be made. In addition to newer approved biologic agents, ocular Behçet's disease is seen to be in better controlled with fewer complications.

Abstract
Objectives Behçet's syndrome (BS) is a chronic multisystemic inflammatory disorder of unclear aetiology. The predominant BS susceptibility locus was identified within HLA-B*51. HLA-B*51 subtypes were previously studied as disease susceptibility markers. Few data are now available about the relationship between B*51 subtypes and clinical phenotype. The aim of this study was to genotype HLA-B*51 subtypes in a series of Italian BS patients and to test the association with clinical manifestations and disease severity (Krause's index). Methods HLA-B*51 subtype genotyping for 63 alleles (B*51:01-B*51:63) was performed by PCR after DNA extraction from whole blood of BS patients. The correlation of disease clinical manifestations and severity (Krause's index) with the HLA-B*51 allele and its subtypes was analysed. Results We enrolled 241 (140 male and 101 female) BS patients, and HLA-B*51 frequency was 62.7% (151 of 241). One hundred and eight of the HLA-B*51-positive patients carried the B*51:01 subtype (108 of 151, 71.5%), 39 of 151 (25.8%) the B*51:08 subtype, 2 of 151 (1.3%) the B*51:02 subtype, 1 of 151 (0.7%) the B*51:05 subtype, and 1 of 151 (0.7%) the B*51:07 subtype. We found that ocular involvement was statistically associated with HLA-B*51 positivity and with B*51:01 and B*51:08 subtypes (P < 0.05). We also found that disease severity was higher in HLA-B*51-positive patients than in negative patients, but without statistical significance (median Krause's index 5.1 vs 4.1, P > 0.05). Conclusion Here, we confirm a high frequency of the HLA-B*51 allele in our group of BS patients. B*51:01 and B*51:08 were found to be the most common subtypes, and an association of both subtypes with ocular involvement was also underlined.

Abstract
OBJECTIVE The aim of this study was to analyze HLA alleles in patients with Behçet disease (BD) and their correlation with ophthalmic manifestations (OMs) in a multiethnic Brazilian population. METHODS This case-control study compared 72 BD patients with or without OM who underwent a thorough ophthalmologic evaluation, including best-corrected visual acuity, bino-ophthalmoscopy, and HLA analysis, with 144 matched healthy controls. Fluorescein angiography was also performed in the patients with BD and OM. HLA class I (A, B, and C) and II (DRB1, DQB1, and DQA1) typing were performed using PCR-SSO. RESULTS Of 72 patients with BD, 42 (58%) had OM. The HLA-B*51 and -A*26 alleles were more frequent in patients with BD than in controls (23.6% vs 14.6% and 12.5% vs 4.3%, respectively), but could not differentiate OM risk. The HLA alleles of BD patients that differentiated those with and without OM were HLA-B*15 (40.5% vs 20.7%; odds ratio [OR], 2.59; p = 0.0059), HLA-C*02 (33.3% vs 13.4%; OR, 3.20; p = 0.0024), and HLA-DQB1*03 (64.3% vs 45.7%, p = 0.017), whereas HLA-A*03 (0.0% vs 13.3%, p = 0.006) and HLA-DRB1*15 (4.8% vs 19.5%; OR, 0.21; p = 0.0121) were protective against OM. CONCLUSIONS In this study of a Brazilian multiethnic BD population, alleles were similar between groups of BD patients with and without OM. We described HLA-B*15, -C*02, and -DQB1*03 as risk factors and -A*03 and -DRB1*15 as protective factors for OM in BD, which could function as biomarkers for predicting disease phenotypes.

Abstract
Behcet's disease (BD) is a chronic multi-systemic disease characterized by relapsing-remitting oral ulcers, genital ulcers, ocular inflammatory involvements, and numerous other systemic features. Ocular involvements are quite common in BD and may cause severe tissue damage and potentially blindness. Even though the pathogenesis of BD remains ambiguous, growing evidences have shown that genetic factors, environmental triggers and immunological abnormalities play significant roles in its development and progression. Novel biotherapies targeting IFN-γ, TNF-α and interleukins have been used in recent years. In this review, we mainly pay attention to the ocular involvement of BD, and discuss the current understanding of mechanisms and advances in therapeutic approaches, especially novel biologics. Finally, we discuss the management in patients with pregnancy.

Abstract
Behçet's disease is a systemic vasculitis that affects multiple organs. The most common manifestations are oral and genital ulcerations and recurrent uveitis. Uveitis can be an initial symptom in 10-20% of cases and leads to blindness in 16-25% of patients. The management of this disease is evolving due to the clinical phenotypes recently described in the literature and increasing focus on the detection of subclinical inflammation to enable correct therapeutic decisions. The first line treatment is azathioprine, followed by various immunosuppressive and biological agents as alternatives in severe or refractory cases. This review summarizes scientific articles about the etiology of, diagnostic tools for and treatment of the ocular manifestations of Behçet's disease available in the PubMed database from 1 January 2016 to 1 May 2021. A multidisciplinary approach is necessary to effectively prevent permanent damage and thus improve the life quality of the patients. Therefore, it is crucial to raise awareness of the common clusters of symptoms, use of modern imaging methods, such as ocular computed tomography and fluorescein angiography, and novelty treatment algorithms to enable early diagnosis and appropriate management.

Abstract
Uveitis is a generic term for inflammation of the uvea, which includes the iris, ciliary body, and choroid. Prevalence of underlying non-infectious uveitis varies by race and region and is a major cause of legal blindness in developed countries. Although the etiology remains unclear, the involvement of both genetic and environmental factors is considered important for the onset of many forms of non-infectious uveitis. Major histocompatibility complex (MHC) genes, which play a major role in human immune response, have been reported to be strongly associated as genetic risk factors in several forms of non-infectious uveitis. Behçet’s disease, acute anterior uveitis (AAU), and chorioretinopathy are strongly correlated with MHC class I-specific alleles. Moreover, sarcoidosis and Vogt-Koyanagi-Harada (VKH) disease are associated with MHC class II-specific alleles. These correlations can help immunogenetically classify the immune pathway involved in each form of non-infectious uveitis. Genetic studies, including recent genome-wide association studies, have identified several susceptibility genes apart from those in the MHC region. These genetic findings help define the common or specific pathogenesis of ocular inflammatory diseases by comparing the susceptibility genes of each form of non-infectious uveitis. Interestingly, genome-wide association of the interleukin (IL)23R region has been identified in many of the major forms of non-infectious uveitis, such as Behçet’s disease, ocular sarcoidosis, VKH disease, and AAU. The interleukin-23 (IL-23) receptor, encoded by IL23R, is expressed on the cell surface of Th17 cells. IL-23 is involved in the homeostasis of Th17 cells and the production of IL-17, which is an inflammatory cytokine, indicating that a Th17 immune response is a common key in the pathogenesis of non-infectious uveitis. Based on the findings from the immunogenetics of non-infectious uveitis, a personalized treatment approach based on the patient’s genetic make-up is expected.

Abstract
This study investigated the expression status of signaling lymphocytic activation molecule family 6 (SLAMF6) in CD8+ T lymphocytes of patients with severe aplastic anemia (SAA) and its association with the clinical indicators and immune status of the disease. The effects of SLAMF6 on the function and apoptosis of CD8+ T lymphocytes were also investigated. Levels of SLAMF6 and SLAM-associated protein in the CD8+ T lymphocytes of SAA patients were significantly lower than the normal controls, and they were positively correlated with hematopoietic-related indicators but negatively correlated with the levels of functional molecules of CD8+ T lymphocytes. After blocking SLAMF6, CD8+ T lymphocyte functional molecule secretion was upregulated and RICD was downregulated in SAA patients, suggesting that SLAMF6, is involved in the pathogenetic mechanism of SAA by regulating CD8+ T lymphocyte functional molecule secretion and RICD levels. SLAMF6 may be a novel target for the regulation of CD8+ T lymphocyte homeostasis.

Abstract
Human leukocyte antigen (HLA), also known as human major histocompatibility complex (MHC), is encoded by the HLA gene complex, and is currently known to have the highest gene density and the most polymorphisms among human chromosomal areas. HLA is divided into class I antigens, class II antigens, and class III antigens according to distribution and function. Classical HLA class I antigens include HLA-A, HLA-B, and HLA-C; HLA class II antigens include HLA-DP, HLA-DQ, and HLA-DR; nonclassical HLA class I and II molecules include HLA-F, E, H, X, DN, DO, and DM; and others, such as complement, are class III antigens. HLA is closely related to the body's immune response, regulation, and surveillance and is of great significance in the study of autoimmune diseases, tumor immunity, organ transplantation, and reproductive immunity. HLA is an important research topic that bridges immunology and clinical diseases. With the development of research methods and technologies, there will be more discoveries and broader prospects.

Abstract
Systemic vasculitides are multisystem blood vessel disorders, which are defined by the size of the vessel predominantly affected, namely small, medium, or large vessels. The term "large vessel" relates to the aorta and its major branches; "medium vessel" refers to the main visceral arteries and veins and their initial branches. The most common causes of large-vessel vasculitis are giant cell arteritis and Takayasu arteritis, and those of medium-vessel arteritis are polyarteritis nodosa and Kawasaki disease. However, there is some overlap, and arteries of any size can potentially be involved in any of the 3 main categories of dominant vessel involvement. In addition to multisystem vasculitides, other forms of vasculitis have been defined, including single-organ vasculitis (eg, isolated aortitis). Prompt identification of vasculitides is important because they are associated with an increased risk of mortality. Left undiagnosed or mismanaged, these conditions may result in serious adverse outcomes that might otherwise have been avoided or minimized. The ethnic and regional differences in the incidence, prevalence, and clinical characteristics of patients with vasculitis should be recognized. Because the clinical presentation of vasculitis is highly variable, the cardiovascular clinician must have a high index of suspicion to establish a reliable and prompt diagnosis. This article reviews the pathophysiology, epidemiology, diagnostic strategies, and management of vasculitis.

Abstract
Behçet's disease is a chronic, multisystem inflammatory disorder characterized by relapsing inflammation. Although its etiopathogenesis has not yet been clarified, both the adaptive and innate immune systems, genetic predisposition, and environmental factors have all been implicated. It is more frequent and more severe in males in the third and fourth decades of life. The eye is the most frequently involved organ in the course of the disease. Ocular involvement (Behçet's uveitis) is characterized by bilateral recurrent non-granulomatous panuveitis and occlusive retinal vasculitis. Recurrent inflammatory episodes in the posterior segment may lead to permanent vision loss due to irreversible retinal damage and complications such as macular scarring, macular atrophy, and optic atrophy. Early and aggressive immunomodulatory treatment and the use of biologic agents when needed are crucial for preventing recurrences and improving visual prognosis.

Inflammopharmacology 2020; 28:819-829.

Abstract
BACKGROUND AND AIMS Behçet's disease (BD) is an auto-immune vasculitis, characterized by episodic inflammation of multiple organs. The neutrophil to lymphocyte ratio (NLR) is used as a marker of inflammation in several diseases nowadays. While nitric oxide (NO) seem to be involved in BD pathogenicity. Our study aims to investigate the NLR as an inflammatory marker of BD activity as well as to evaluate the relationship between the NO production and NLR in Algerian BD patients with different clinical manifestations before and under colchicine + corticosteroid treatment. METHODS For this purpose, we evaluated the NLR as the ratio of neutrophil count to lymphocyte count in naïve and treated active BD patients with different clinical manifestations and in inactive ones. Furthermore, we assessed NO production by the Griess' method in the same patients. Additionally, we evaluated in vivo interferon-γ (IFN-γ) and interleukin-4 (IL-4) levels using ELISA. RESULTS AND DISCUSSION Our results indicate that the NLR and nitrite levels were higher in naïve active BD patients. Interestingly, this high ratio and NO production differed according to the clinical manifestations and was associated with an increased risk of mucocutaneous and vascular involvement. Importantly, in treated BD patients NLR was higher in active patients especially in those with mucocutaneous involvement while increased nitrites levels were regardless of the clinical manifestations studied. Both NLR and NO production decreased in these treated active patients. In addition, IL-4 production differed according to the clinical manifestations studied contrary to the IFN-γ production. CONCLUSION Collectively our results suggest that the NLR is a potential marker of BD activity in Algerian patients, predicting the disease severity. Moreover, the positive relationship between the NLR and NO production is related to an increased risk of mucocutaneous lesions and vascular involvement. Thus, the application of these two accessible tools could be benefit for the clinical prognosis and treatment of BD.

Abstract
AIMS To investigate susceptible human leukocyte antigen (HLA) alleles and their associations with clinical features in Thai patients with Behçet's disease (BD). METHOD Eighteen HLA-A and 36 HLA-B alleles were determined in 42 Thai BD patients and 99 healthy controls (HCs) by reverse line blot assay, and reconfirmed by MICRO SSP assay. RESULTS The BD patients had significantly higher allele frequency (AF) of HLA-B*51 than the HCs (13.10% vs 5.05%, P = .025). The AF of HLA-A*26, -A*26:01 and -B*51:01 also was higher and almost reached statistical significance (5.59% vs 1.52%, P = .054, 5.95% vs 1.52%, P = .054 and 10.71% vs 4.04%, P = .051, respectively). However, the BD patients had significantly higher AF of either HLA-A*26:01 or -B*51:01 (16.67% vs 5.56%, P = .005), or -A*26:01 or -B*51X (19.05% vs 6.56%, P = .003). The AF of HLA-B*51:01 and -B*51X increased significantly in -A*26:01 non-carrier BD patients (12.16% vs 4.17%, P = .024 and 14.86% vs 5.21%, P = .019, respectively); and that of HLA-A*26:01 was significantly higher in -B*51X non-carrier BD patients (7.58% vs 1.67%, P = .034). HLA-B*51:01 associated significantly with the presence of posterior uveitis and visual impairment (18.18% vs 2.50%, P = .031 for both conditions). HLA-B*51:01 was not observed in BD patients with gastrointestinal involvement or arthritis. Furthermore, the AF of HLA-B*51:01 was significantly higher in HLA-A*26:01 non-carrier BD patients without arthritis (17.30% vs 0%, P = .050). CONCLUSION HLA-B*51:01 was a susceptible allele for Thai BD patients, and associated with posterior uveitis and visual impairment. HLA-A*26:01 was another susceptible allele in HLA-B*51X non-carrier patients. The protective effect of HLA-B*51:01 on arthritis needs further investigation.

Abstract
BACKGROUND How HLA-A26 modulates Behçet's disease (BD) ocular lesions such as iridocyclitis and retinochorioiditis has not been scrutinized. METHODS Ministry of Health, Labour and Welfare of Japan provided us a database of BD patients who were registered from 2003 to 2014. We selected patients who satisfied International Criteria for BD and whose data for HLA-A26 was available. RESULTS Eligible 557 patients consisting of 238 men (42.7%) and 319 women (57.3%), whose median age was 38 years old (interquartile range 29-47) were analyzed. Prevalence of general ocular lesions, iridocyclitis, retinochorioiditis, and chronic lesions were 43.1%, 30.7%, 34.1%, and 17.4%, respectively. The prevalence of ocular lesions was higher among HLA-A26 carriers compared to that among HLA-A26 non-carriers with odds ratio (OR) of 2.5 (95% confidence interval (95% CI) 1.8-3.5, p < .001) for general ocular lesions, OR of 2.5 (95% CI 1.7-3.6, p < .001) for iridocyclitis, OR of 2.8 (95% CI 1.9-4.0, p < .001) for retinochorioiditis, and OR of 2.7 (95% CI 1.7-4.3, p < .001) for 'chronic ocular lesion following iridocyclitis or retinochorioiditis'. The HLA-A26 had a similar impact on ocular lesions between HLA-B51 positive and negative cases (Breslow-Day test, p > .05). However, the HLA-A26 had a larger impact on iridocyclitis for men compared to women (Breslow-Day test, p = .040). The male HLA-A26 carriers had higher risk of iridocyclitis with OR of 3.4 (95% CI 2.0-5.9, p < .001), while the OR for women was 1.5 (95% CI 0.9-2.6, p = .146). CONCLUSION HLA-A26 carriers had higher risk for iridocyclitis and retinochorioiditis. However, the impact was more prominent for men.

Abstract
PURPOSE OF REVIEW The orbit is subject to a variety of vascular insults that manifest with both specific and nonspecific patterns of vision compromise. The aim of the following review is to highlight the ophthalmic clinical features of systemic vasculitides that most frequently involve the orbit and differentiate them from the most common non-vasculitic orbital disorders. RECENT FINDINGS New studies continue to explore the autoimmune nature of vasculitic disease and seek to determine optimal use of newer therapies such as biologic agents. The pattern of ocular involvement in the context of clinical history allows the knowledgeable physician to distill a differential diagnosis into a specific or likely cause. Establishing a diagnosis in a timely fashion allows for a custom-tailored approach to therapy.

Abstract
Objectives: To scrutinize the influence of HLA-B51 to each clinical manifestation of patients with Behçet's disease (BD) using a database of the Ministry of Health, Labour and Welfare of Japan.Methods: The database of newly registered patients with BD was obtained from the Japanese Ministry of Health, Labour and Welfare. Patients who met International Criteria for Behçet's Disease (ICBD) and had data for HLA-B51 were selected and analyzed.Results: Among the 3044 analyzable cases, 1334 (43.8%) were men and 1710 (56.2%) were women; the median age was 38 years (IQR 29-48). HLA-B51 was positive for 1334 (44.5%). Prevalence of selected manifestations was 98.5% for oral ulceration, 85.5% for skin lesion, 42.1% for ocular lesion, 69.1% for genital ulceration, and 29.0% for gastrointestinal symptom. HLA-B51-positive patients had higher risk for ocular lesion (OR 1.59, 95%CI: 1.37-1.84; p < .001) and lower risk for genital ulceration (OR 0.72, 95%CI: 0.62-0.84; p < .001) and gastrointestinal symptom (OR 0.65, 95%CI: 0.55-0.77; p < .001). No significant difference was observed for other organ involvement; oral ulceration, skin lesion, positive pathergy test, arthritis, epididymitis, vascular lesion, or neurological manifestation. Subgroup analyses revealed that HLA-B51 was not related to genital ulceration in the cases with an ICBD score of 6 or higher and that HLA-B51 tended to more largely affect the risk of three manifestations for men compared to that for women.Conclusion: HLA-B51 positive is a risk factor for ocular lesion and vice versa for genital ulceration and gastrointestinal symptoms in patients with Japanese BD.

Abstract
Patients with Behçet's disease (BD) suffer from episodic ocular and mucocutaneous attacks, resulting in a reduced quality of life. The phenotype of Japanese BD has been changing over the past 20 years, and the rate of human leukocyte antigen (HLA)-B*51-positive complete type is decreasing while that of intestinal type is increasing. This phenotypical evolution may be related to changes in as-yet-unknown environmental factors, as the immigration influx in Japan is low. Mechanisms discovered by genome-wide association studies include ERAP1-mediated HLA class I antigen bounding pathway, autoinflammation, Th17 cells, natural killer cells, and polarized macrophages, a similar genetic architecture to Crohn's disease, ankylosing spondylitis, and psoriasis. As for treatments, management guidelines have been implemented, and the development of tumor necrosis factor (TNF) inhibitors is markedly improving the outcome of BD, but evidence supporting treatment for special-type BD is limited. The classification of BD into distinct clusters based on clinical manifestations and genetic factors is crucial to the development of optimized medicine.

Abstract
BACKGROUND Behçet's Disease (BD, OMIM 109650) is a chronic relapsing inflammatory disease of unknown etiology with unpredictable exacerbations and remissions. First described in 1937 by the Turkish dermatologist HulusiBehçet, as a trisympton complex (oral and genital ulcers and uveitis), it is now recognized as a multisystemic disease. The syndrome can manifest in diverse ways and can involve nearly every organ system. Several studies have implicated T cells and monocytes in the pathogenesis of BD especially when these cells are stimulated by heat shock proteins and streptococcal antigen. This article presents a review of the relevant published literature about the immunopathogenesis of BD. RESULT The authors used MeSH terms "Behçet's disease" with "pathophysiology," "pathogenesis," "genetic", "epigenetic", "immunogenetic" or "immune response" to search the PubMed database. All the relevant studies identified were included.

Abstract
Cerebral vasculitis is a rare disorder but plays a major role in the differential diagnosis of stroke, encephalopathy and headache. This guideline was developed in order to support clinicians in the diagnosis and treatment of primary angiitis of the CNS (PACNS) and Neuro-Behçet. It is based on a medline research and was developed in a modified Delphi process and approved by the involved societies. This article is an abridged and translated version of the guideline published in DGNeurologie: Berlit, P. & Krämer, M. DGNeurologie (2018) 1: 17. 10.1007/s42451-018-0001-y

Frequency of HLA-B5, HLA-B51 and HLA-B27 in patients with idiopathic uveitis and Behçet's disease: a case-control study. Reumatologia 2018; 56:67-72. [PMID: 29853720 PMCID: PMC5974627 DOI: 10.5114/reum.2018.75516] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2017] [Accepted: 04/11/2018] [Indexed: 11/30/2022] Open
Abstract
Objectives Idiopathic uveitis is the most common form of uveitis in most countries. Uveitis affects about 40–80% of patients with Behçet’s disease (BD). Class I, HLA-B5, and its subclass B51 allele have the strongest association with BD, but its role in idiopathic uveitis is unclear. The aim of this study was to determine the frequency of HLA-B5, HLA-B51 and HLA-B27 in patients with idiopathic uveitis, BD and the control group. Material and methods Forty-eight patients with idiopathic uveitis, 62 patients with BD, and 49 control subjects were compared. The presence of HLA-B5, HLA-B51 and HLA-B27 was checked by reviewing the charts of patients with idiopathic uveitis and Behçet’s disease referred to the rheumatologic center of Shiraz University of Medical Sciences. The control group consisted of a sex-matched normal control population, among which HLA typing was done. Results HLA-B5 was significantly higher in patients with idiopathic uveitis and BD compared to the control group (p = 0.029 and 0.0001). It was significantly higher in patients with BD compared to those with idiopathic uveitis (p = 0.001). The difference of HLA-B51 between the groups was not statistically significant although it was higher in the BD group than the controls. The presence of HLA-B51 was significantly associated with ocular involvement in the BD group (p = 0.013). HLA-B27 was the least common type of HLA in all groups. Conclusions HLA-B5 was the most common, compared to HLA-B51 and HLA-27, in patients with idiopathic uveitis and BD. There was an association between HLA-B51 positivity and ocular involvement in patients with BD. It seems that the pattern of HLA in our patients with idiopathic uveitis was different from that observed in some other studies.

Abstract
PURPOSE To study the incidence and epidemiology of Behcet's disease in Taiwan. METHODS This retrospective cohort study was conducted using the nationwide reimbursement database in Taiwan. One million registered beneficiaries of the Taiwan National Health Insurance system in 2000 were randomly selected. All medical claims of these persons were collected. The definition of having Behcet's disease was based on diagnostic codes. Persons who had incomplete registry data or diagnoses prior to 2001 were excluded. Annual incidence between 2001 and 2011 was calculated and risk factors for incidence were explored using the Cox proportional regression model. Characteristics of patients with Behcet's disease with and without uveitis were compared. RESULTS A total of 236 newly diagnosed patients with Behcet's disease were found between 2001 and 2011. The average incidence was 2.40 cases per 100,000 person-years (ranging from 1.29 to 3.53). Female patients and those aged between 40 and 65 years were at the highest risk of Behcet's disease. Only 18.2% of the patients had also suffered from uveitis. The subspecialties of doctors making initial diagnoses and the number of prescribed immunomodulatory agents differed significantly between the patients with and without uveitis (p < 0.001 and <0.05, respectively). CONCLUSION Incidence of Behcet's disease was not high in Taiwan and relatively few of the patients developed uveitis. Patients of working age or who were female were more likely to have Behcet's disease. However, age of onset and clinical severity differed between patients with and without uveitis.

Abstract
BACKGROUND AND AIMS Behçet's disease (BD) is a chronic multisystemic inflammatory disease with complex etiopathogenesis. Th1-proinflammatory cytokines seem to be involved in its pathogenesis. Our current study aims to evaluate interleukin-18 (IL-18) and nitric oxide (NO) involvement in the development of different clinical manifestations of BD as well as to investigate the corticosteroid therapy effect on this production in Algerian patients. METHODS For this purpose, we evaluated in vivo and ex vivo IL-18, interferon-γ (IFN-γ) levels using ELISA and NO production by the Griess' method in naïve-active and corticosteroid-treated BD patients with different clinical manifestations. Additionally, we assessed CD40/CD40L expression by flow cytometrics assay in these groups of patients. RESULTS AND DISCUSSION Our results indicate that IL-18 and nitrite levels were higher in naïve-active BD patients. Interestingly, this high production differed according to the clinical manifestations and was associated with an increased risk of mucocutaneous and vascular involvement. Concerning corticosteroid treated-active BD patients, no difference was observed in this production between each clinical subgroup. However, IFN-γ levels increased in all categories of active patients. Interestingly, corticosteroid therapy reduced significantly these inflammatory mediators regardless of the clinical manifestations studied. In addition, the CD40/CD40L expression differed according to the clinical presentations. CONCLUSION Collectively, our results suggest that concomitant high production of IL-18 and NO in naïve-active BD patients is related to an increased risk of mucocutaneous lesions and vascular involvement. Moreover, the relationship between these two inflammatory markers could constitute a predictable tool of BD clinical presentations and an early factor of therapy efficiency.

Abstract
BACKGROUND The epidemiology of Adamantiades-Behçet's disease varies among ethnic populations worldwide. Trends in the incidence of Adamantiades-Behçet's disease have not been investigated based on the Korean National Health Insurance database. OBJECTIVES This study investigated the incidence and mortality of Adamantiades-Behçet's disease by age using nationwide population data in Korea. METHODS A nationwide population-based cohort study was performed using the Korean National Health Insurance Claims Database from 2006 to 2015. The incidence of Adamantiades-Behçet's disease was calculated by age, sex, calendar year and habitat. And comorbid metabolic diseases were also analysed in patients with Adamantiades-Behçet's disease. RESULTS The annual incidence of Adamantiades-Behçet's disease per 100 000 person-years was 3.976 (2.587 for males and 5.373 for females) from 2006 to 2015. The incidence of Adamantiades-Behçet's disease peaked among people in their 40s (6.561 per 100 000 person-years). Incidence was significantly higher in subjects with comorbid metabolic conditions, such as diabetes mellitus, hypertension and dyslipidemia. The mortality rate per 1000 person-years increased with age in patients with Adamantiades-Behçet's disease. CONCLUSIONS This study showed the incidence, prevalence and mortality of Adamantiades-Behçet's disease. Metabolic conditions increased the risk of Adamantiades-Behçet's disease among Koreans.
