Abstract
BACKGROUND High mobility group box- 1 (HMGB- 1) is a nuclear protein acting as a proinflammatory molecule. The serum HMGB- 1 levels were found elevated in chronic inflammatory diseases. In this cross-sectional study, serum HMGB- 1 levels in Behcet's disease (BD) patients and healthy controls (HC) were studied. Also, its association with disease activity scores and clinical findings were evaluated. METHODS Ninety BD patients and 50 age-sex matched HC were included in the study. Disease activity scores were assessed by Behcet Disease Current Activity Form (BDCAF) and Behcet Syndrome Activity Score (BSAS). Serum HMGB- 1 levels were measured using a commercial ELISA kit. A p value of < 0.05 was considered to be statistically significant. RESULTS Serum HMGB- 1 levels were significantly higher in BD than in HC (43.26 pg/mL and 16.73 pg/mL; p < 0.001, respectively). Serum HMGB- 1 levels were statistically significantly associated with presence of erythema nodosum (EN) and genital ulcers in the last one month prior to recruitment (p = 0.041 and p < 0.001, respectively). BDCAF and BSAS scores were positively correlated with serum HMGB- 1 level ( p = 0.03 and p = 0.02, respectively). DISCUSSION HMGB - 1 may play a role in the development of BD. Also, due to its positive correlation with disease activity indices, it can be used as a novel disease activity parameter in BD.

Abstract
BACKGROUND Eye involvement is a common and potentially devastating complication of various immune related rheumatic diseases. We aimed to determine the spectrum, associations and the impact of ocular manifestations among well characterised autoimmune rheumatic disease patients presenting to ophthalmology and rheumatology clinics in a tertiary care hospital in Lahore, Pakistan. METHODS Descriptive cross-sectional study performed in Rheumatology department of Fatima memorial hospital. Only those rheumatic disease patients were included who have been attending ophthalmology department for their ophthalmic conditions. The patients with ophthalmic symptoms who have not attended an ophthalmologist were not included in this study. Proforma was designed and the studied parameters were recorded prospectively from patient's interview and also by reviewing patient's medical and ophthalmologic medical records. Parameters assessed were demographics, symptoms and the diagnosis of eye disease, unilateral or bilateral presentation, duration of eye symptoms along with the duration of the primary rheumatologic disease, and the complications of the eye disease whether due to the eye diagnosis or its treatment. RESULTS Eighty-three consecutive patients with mean age 33±11 years, 67.5% being female were recruited. Spondyloarthritis (SpA) comprised 38.6% (n=32) of patients followed by 21.7% (n=18) of Behcet's disease. Majority of patients (68.7%) had bilateral eye symptoms. In our cohort, 70% (n=58) of the patients had uveitis and almost all of these patients had either SpA or Behcet's disease as their primary rheumatologic diagnosis. Scleritis in 15.7% (n=13) patients followed by retinal vasculitis in 9.6% (n=8) patients, while glaucoma and keratopathy were present in 2.4% (n=2) patients each comprised other manifestations. Reassuringly our uveitis patients had no long-term eye related complications either due to the disease or its treatment. CONCLUSIONS Uveitis represented the most common ophthalmologic manifestation associated with underlying rheumatologic diseases in our cohort, and it was associated with underlying Behcet's disease and SpA. Uveitis associated with connective tissue diseases has good prognosis with low-risk of significant long-term complications. Moreover, uveitis associated with SpA was noted to present much earlier in its disease course.

Abstract
Behcet’s disease (BD) is associated with considerable gut microbiome changes. However, it still remains unknown how the composition of the gut microbiome exactly affects the development of this disease. In this study, transplantation of stool samples from patients with active ocular BD to mice via oral gavage was performed. This resulted in decreases of three short chain fatty acids (SCFAs) including butyric acid, propionic acid and valeric acid in the feces of the BD-recipient group. Intestinal barrier integrity of mice receiving BD feces was damaged as shown by a decreased expression of tight junction proteins and was associated with the release of Lipopolysaccharides (LPS) in the circulation. The mice also showed a higher frequency of splenic neutrophils as well as an enrichment of genes associated with innate immune responses in the neutrophils and CD4 + T cells as identified by single cell RNA sequencing. Analysis of neutrophils and T cells functions in these mice showed an enhanced mesenteric lymph node and splenic Th1 and Th17 cell differentiation in association with activation of neutrophils. Transplantation of BD feces to mice and subsequent induction of experimental uveitis (EAU) or encephalomyelitis (EAE) led to an exacerbation of disease in both models, suggesting a microbial adjuvant effect. These findings suggest that the gut microbiome may regulate an autoimmune response via adjuvant effects including increased gut permeability and enhancement of innate immunity.

Abstract
Background Behçet’s disease (BD) is a multisystemic vasculiti where cardiac involvement is not common. Previous studies have shown that the incidence of ventricular arrhythmia and sudden cardiac death (SCD) is higher in patients with BD than in the healthy population. Among various possible explanations, autonomic nervous system (ANS) dysfunction has been suggested. Few studies have evaluated ANS function in patients with BD, and the results obtained are controversial. Objective We aimed to assess cardiac autonomic function by heart rate variability (HRV) in patients with BD; to evaluate circadian changes in HRV; and to study the relationship between HRV parameters and disease parameters. Methods Thirty-six patients with Behçet’s disease (median age 42 years, 28 men) and 36 age- and sex-matched healthy volunteers were included. HRV analyses were performed in the time and frequency domains for the entire 24-hour period and for the daytime and nighttime periods. BD activity was studied with Behcet’s disease current activity form (BDCAF). Results Patients with BD had significantly lower values of SDNN compared to controls. PNN50, RMSSD, and HF components mean values were significantly reduced in patients than in controls implying parasympathetic impairment. LF was comparable between the two groups, whereas LF/HF ratio was significantly higher in BD group. The circadian rhythm of HRV was preserved in patient group. There was no significant correlation of CRP or disease duration with HRV indices in Behçet’s subjects. BDCAF score was found to be negatively correlated with LF/HF. Conclusion Patients with BD, despite no cardiovascular involvement, have reduced parasympathetic activity compared with controls. However, circadian rhythms of autonomic function were preserved. As known, there is strong evidence for the role of the ANS in the pathogenesis of ventricular arrhythmias. Thus, being a practical tool, HRV can be an interesting approach for the rhythmic follow-up of BD patients. ![]()

Abstract
PURPOSE This case-control study aimed to evaluate the possible association of MCP-1 - 2518A/G genetic polymorphism with Behcet's disease (BD) in the Iranian patients. MATERIALS AND METHODS This study was performed in 135 Behcet's patients (51 ocular and 84 non-ocular) and 79 healthy individuals. Peripheral blood samples were genotyped for MCP-1 - 2518A/G using the PCR-RFLP technique. RESULTS The statistical analysis of MCP-1 - 2518A/G showed no significant differences in genotype/allele frequencies between Behcet's patients and controls. There was no significant association in genotype/allele frequencies between either ocular or non-ocular BD patients and controls. Also, different genotype/allele frequencies between ocular and non-ocular BD were not statistically significant. CONCLUSIONS In this study, with a threshold P-value of 0.05 and an estimated power of 0.81 to detect a significant association (odds ratio ≥1.2), we did not observe any association of this variant with Behcet's disease.

Abstract
Purpose: To investigate the incidence and risk factors of blindness in uveitis.Methods: From a national sample cohort (n = 1,025,340), we selected 9,036 new-onset uveitis patients. Incidences of unilateral and bilateral blindness (visual acuities ≤20/400) were estimated and socioeconomic and clinical risk factors for unilateral blindness in uveitis patients were identified.Result: Incidence of unilateral and bilateral blindness was 2.93 and 0.42 per 1,000 person-years, respectively. The risk factors for unilateral blindness were age >40 (hazard ratio [HR], 2.77, 95% CI [confidence interval], 1.11-6.92) and low household income (HR, 1.50; 95% CI, 1.02-1.98) in uveitis overall, and Behçet's disease (HR, 4.49; 95% CI, 1.59-12.71) in non-anterior uveitis, respectively.Conclusions: Low household income and Behçet's disease influence the risk of blindness in uveitis patients. These findings will help in assessing blindness-related socioeconomic burdens and planning health-care strategies for uveitis patients.

Abstract
BACKGROUND Behcet's disease (BD) may present with life threating complications including neurological and cardiovascular involvement. Neuro-Behcet's disease (NBD) is one of the most important causes of morbidity and mortality in patients with BD. The aim of the present study is to investigate whether patients with NBD are different than BD patients with other manifestations in terms of subclinical myocardial dysfunction. METHODS Forty patients with NBD (23 female, mean age: 42.4 ± 9.4 years), 40 patients with BD (9 female, mean age: 39.7 ± 9.0 years) and 40 controls (20 male, mean age: 41.8 ± 6.5 years) were consecutively included in the study. All subjects underwent a transthoracic echocardiography for evaluation of left ventricular (LV) and atrial (LA) functions with two-dimensional (2D) speckle tracking echocardiography (STE). RESULTS Baseline characteristics, clinical data, LV dimensions, systolic and diastolic functions were all in normal range among the groups. LV global longitudinal strain (LV-GLS) was significantly lower in patients with NBD and BD patients without neurologic involvement compared to controls. LA conduit strain was significantly lower in patients with NBD compared to controls. Patients with both parenchymal NBD and vascular NBD manifestations had significantly lower LV-GLS and LA conduit strain compared to controls. Linear regression analysis demonstrated that among cardiovascular risk factors only presence of NBD was the independent predictor of LV-GLS. CONCLUSIONS BD is associated with impaired LV and LA functions. LV-GLS and LA conduit strains of the patients with NBD were lower. NBD was an independent predictor of LV-GLS, suggesting a link between neurological manifestations and cardiac dysfunction in BD patients.

Abstract
PURPOSE To know the clinical and demographic pattern, and the outcome of treatment of Behcet's disease (BD) cases in Nepal METHODS: Retrospective series of all the cases of BD who had come over the period of 12 years (Jan 2007-Dec 2015) Tilganga Institute of Ophthalmology. RESULT Twenty-one cases were included, 17 (81%) male and four (19%) female. Mean age was 28.88 ± 9.18 years. Mean follow-up period was 3.6 ± 2.6 years. All had nongranulomatous panuveitis. Hypopyon was seen in 13 (61.9%) cases. Small retinal infiltrates in 13 (61.9%) cases and retinal vasculitis in ten (47.6%) cases were seen. Cataract (in 13, 61.9%) and optic atrophy (in 11, 52.4%) cases were present. Oral ulcer was present in 20 (95.2%), genital ulcer in 15 (72%), and skin lesions in 13 (62%) cases. CONCLUSION BD affected mainly the most active age group and was predominant in male. Optic atrophy was the leading cause of irreversible vision loss. Despite being a less common condition, BD should be considered in the differential diagnosis of panuveitis cases in the Nepalese population.

Abstract
OBJECTIVES The current trial was conducted to assess the effect of diode laser therapy compared to topical corticosteroid in management of oral ulcers of BD. MATERIALS AND METHODS Fifty patients were divided randomly into two parallel groups. The first group received 980 nm diode laser; the second group received topical corticosteroid (0.1% triamcinolone acetonide). The outcome measures included oral ulcer activity index (composite index), pain (VAS), number of oral ulcers, healing time, and oral health-related quality of life (OHIP-14). The collected data were analyzed for any statistical significance. RESULTS A statistically significant difference was detected between laser and corticosteroid groups favoring laser on comparing composite index and VAS scores on the first and third days and on comparing number of ulcers on the third and fifth days. A statistically significant difference was detected between laser and corticosteroid groups on comparing scores of the questions assessing discomfort with eating food, irritability with other people, taste worsening, unsatisfactory diet, and painful aching on the first and/or third days. No adverse effects were reported by participants of both groups. CONCLUSIONS Diode laser is efficient safe treatment modality for management of BD-associated oral ulcers. Diode laser was more efficient than triamcinolone acetonide in controlling pain and reducing oral ulcer activity. CLINICAL RELEVANCE Laser therapy is efficient safe modality that could spare BD patient from adding a new medication to their long list, being just one visit compared to other regular daily regimen medications.

Abstract
Hugh-Stovin Syndrome (HSS) is characterized by recurrent thrombophlebitis and multiple pulmonary and/or bronchial artery aneurysms indistinguishable from the cardiovascular features seen in Behcet's disease (BD). Our case describes a 30-year-old male with recurrent pulmonary embolism and bilateral pulmonary aneurysms. Autoimmune, hypercoagulable, and infectious work up were negative. Elevated inflammatory markers and absence of the typical clinical findings seen in BD led to the diagnosis of Hugh-Stovin syndrome (HSS). Immunosuppression using steroids and azathioprine led to clinical response. Anticoagulation was continued based on risk/benefit ratio.

Abstract
Objective To develop and validate the evidence-based and consensus-based Behçet’s Syndrome Overall Damage Index (BODI). Methods Starting from 120 literature-retrieved preliminary items, the BODI underwent multiple Delphi rounds with an international multidisciplinary panel consisting of rheumatologists, internists, ophthalmologists, neurologists, and patient delegates until consensus was reached on the final content. The BODI was validated in a cross-sectional multicentre cohort of 228 patients with Behçet’s syndrome (BS) through the study of (a) correlation between BODI and Vasculitis Damage Index (VDI) and (b) correlation between BODI and disease activity measures (ie, Behçet’s Disease Current Activity Form (BDCAF), Physician Global Assessment (PGA), Patient Global Assessment (PtGA)), c) content and face validity and (d) feasibility. Results The final BODI consists of 4 overarching principles and 46 unweighted-items grouped into 9 organ domains. It showed good to excellent reliability, with a mean Cohen’s k of 0.84 (95% CI 0.78 to 0.90) and a mean intra-class correlation coefficient of 0.88 (95% CI 0.80 to 0.95). Overall, 128 (56.1%) patients had a BODI score ≥1, with a median score of 1.0 (range 0–14). The BODI significantly correlated with the VDI (r=0.693, p<0.001), demonstrating to effectively measure damage (construct validity), but had greater sensitivity in identifying major organ damage and did not correlate with disease activity measures (ie, BDCAF: p=0.807, PGA: p=0.820, PtGA: p=0.794) discriminating damage from the major confounding factor. The instrument was deemed credible (face validity), complete (content validity) and feasible by an independent group of clinicians. Conclusions Pending further validation, the BODI may be used to assess organ damage in patients with BS in the context of observational and controlled trials.

Abstract
BACKGROUND Behcet's disease (BD) is an autoimmune disorder with the serious possibility of blindness, calling for further research on its pathogenesis. Our aim was to study the metabolite composition of sweat in BD and to identify possible biomarkers. METHODS Metabolomics analysis was performed on sweat samples from 20 BD patients and 18 normal controls by liquid chromatography tandem mass spectrometry. RESULTS A significantly different metabolic profile of sweat was observed when BD patients were compared with healthy controls. The result of the orthogonal partial least squared-discrimination analysis (OPLS-DA) showed that these two comparison groups could be separated with a relatively satisfactory fitting degree (R2Y = 0.995 and Q2 = 0.817 in positive ion mode; R2Y = 0.991 and Q2 = 0.721 in negative ion mode). Based on OPLS-DA, a panel of metabolites was selected as candidate biomarkers, including l-citrulline, l-pyroglutamic acid, urocanic acid, 2-oxoadipic acid, cholesterol 3-sulfate, and pentadecanoic acid. CONCLUSION This is the first report on the metabolite profile of sweat in BD. Our results demonstrated a significantly different metabolite composition of sweat in BD compared to that of healthy controls.

Abstract
Behçet's disease (BD) is a multisystem inflammatory disorder of unknown etiology, characterized by oral and genital ulceration, with other complications including eye, skin, joint, and central nervous system (CNS) lesions. Diagnosis is based on clinical findings, which may differ between patients. There is a strong genetic basis for BD; however, only a few genes have been associated with the disease across the geographical spread of BD. In this article, we discuss the history and combination of genes involved in this complex disease in relation to the geographical range and present our view that the disease has developed from a Darwinian perspective, with different gene polymorphisms that affect the same biological pathway. Moreover, these mutations individually are protective mechanisms against the disease relevant to each region, which affected both archaic and modern humans.

Abstract
OBJECTIVE To investigate the clinical characteristics of patients with systemic vasculitis in China by analyzing the data from a nationwide registry database, the Chinese Registry for Systemic Vasculitis (CRSV). METHODS The demographic data, clinical presentations, image and laboratory test results, disease activity assessment, treatment, and outcome of patients enrolled with the confirmed diagnosis of systemic vasculitis, including Takayasu's arteritis (TAK), ANCA-associated vasculitis (AAV), Behcet's syndrome (BD), Polyangitis nodosa (PAN), and unclassified systemic vasculitis (USV), were collected since July 2013 in the CRSV. The data during July 2013 and February 28 of 2020 were retrieved and analyzed. RESULTS Up to February 2020, 3852 patients in total were registered in the CRSV. In Peking Union Medical College Hospital (PUMCH), 1348 patients were registered, including 730 patients with TAK, 343 with Behcet's disease (BD), 191 with AAV, 53 with USV, and 31 with PAN. More male patients were found in PAN (64.5%), BD (59.8%), and AAV (52.4%), while TAK was more prevalent in female patients (85.9%). The average age at disease diagnosis was 29.6 in TAK, 33.2 in BD, 28.6 in PAN, 39.4 in USV, and 48.1 in AAV. A significant difference was found between age at diagnosis of TAK and AAV. Gender comparisons revealed that the age at diagnosis of male patients with AAV was older than female patients. Hypertension (57.3%) and stroke (17.5%) were found to be more common in male patients with TAK, vascular involvement (27.3%) was found to be more common in male patients with BD, while neurological involvement (29.0%) was found to be more common in male patients with AAV than in females. CONCLUSION This registry is the first in China and provides rich information about the clinical characteristics of Chinese patients with systemic vasculitis. There are significant differences in clinical presentations between different categories of systemic vasculitis.

Abstract
Introduction Behcet's Disease (BD) is an inflammatory disease characterized by multisystemic involvement and featured by a chronic, relapsing disease course. Recurrent ocular inflammation and macular involvement may lead to severe loss of visual acuity. Prolonged use of local and systemic corticosteroids lead to numerous side effects and complications. Very often other immunosuppressive therapies are needed. Biologic agents are promising for the treatment of Behcet's disease-associated uveitis. Aim To report successful treatment of paediatric uveitis due to incomplete Behçet's disease with administration of adalimumab, after failing to react to all other modalities of treatment. Case report We present the case of a 15-year-old girl who was treated for reccurent uveitis in both eyes with developed complications on anterior and posterior ocular segment. She was earlier treated with topical and systemic steroids for uveitis, laser photocoagulation and methotrexate, however, relapses occurred inspite all treatment modalities. Patient was diagnosed with incomplete Behcet's disease, and adalimumab therapy was initiated. Inflammation was well-controlled by adalimumab administration without need for local or systemic corticosteroids. Conclusion Adalimumab is effective for treating children with Behcet's disease-associated uveitis. Control of ocular inflammation in our case was achieved without need for continuing local or systemic corticosteroids, thus preventing further complications and possible significant vision loss.

Abstract
Purpose of Review To assess current management of Behcet’s disease (BD). Controversies on therapeutic approaches to different manifestations, whether conventional immunosuppressives (IS) or biologic agents, should be chosen, and options for refractory disease are discussed. Recent Findings Glucocorticoids are still the main agents for remission-induction and azathioprine the first-line conventional IS in maintenance phase to prevent relapses of major organ involvement. Apremilast is shown to be a safe and effective option approved by the FDA for oral ulcers. Large case series confirmed the efficacy and safety of TNFα inhibitors and Interferon-α. Promising results are observed with IL-1 inhibitors, ustekinumab, secukinumab, and tocilizumab for refractory BD. Summary Although both conventional IS and biologic agents are effectively used to suppress inflammation in BD, there is still an unmet need for clear therapeutic strategies in the management for different manifestations. Further controlled studies with new biologic agents, anticoagulants and the benefit of concomitant IS usage with biologics are needed to optimize the management of BD.

Abstract
OBJECTIVES Behcet's disease is a multisystem disorder of unknown etiology with vascular complications. This study reviewed the mid-term outcome of Behcet's disease patients with carotid artery pseudo-aneurysms treated by endovascular stent-graft repair at our unit. METHODS During a period of 11 years, six cases were included. Postoperative ultrasound duplex results were recorded along with computed tomography angiography report done a year after intervention. RESULTS The mean age (±SD) was 38 (±5.2) years. The mean (±SD) pseudo-aneurysm size was 33 (±12.2) mm. Technical success was 83%; failed cannulation of the internal carotid artery was encountered in one case. On day 2 post-operative, a duplex ultrasound revealed complete exclusion and thrombosis of the false aneurysm in all cases. A year later, a computed tomography angiography revealed a primary patency rate of 80%, and only one case had a recurrent pseudo-aneurysm at the distal margin of the stent graft. All cases, however, had complete thrombosis in the pseudo-aneurysms lumen with a mean (±SD) regression in size of 18 (±6) mm. The mean (±SD) percentage of in-stent stenosis was 34.5% (±11.73%). CONCLUSIONS Stent graft repair for carotid artery pseudo-aneurysm in Behcet's disease patients might be the preferable first line of treatment since it had a high technical success and mid-term primary patency rates, with additional fact that it obviously avoids the hazardous complications of surgery.

Abstract
Purpose: Uveitis can be associated with meningitis (uveomeningitis) and the inflammation shared with the central nervous system. We aimed to describe the characteristics and outcome of uveomeningitis.Methods: We retrospectively analyzed 110 consecutive adult patients with uveomeningitis.Results: The main causes of uveomeningitis were Vogt-Koyanagi-Harada (31%), syphilis (16%), sarcoidosis (12%), Behçet's disease (7%), and multiple sclerosis (5%). Sixteen percent of uveomeningitis remained of undetermined origin. Compared to etiology-matched uveitis without meningitis, patients with uveomeningitis were younger, had more frequent neurological manifestations, and had more frequent abnormal cerebral magnetic resonance imaging findings. In contrast, no ocular feature upon examination was significantly associated with the presence of meningitis. Patients with uveomeningitis were more frequently treated with immunosuppressants but uveitis relapse and systemic complications did not differ between groups.Conclusion: Uveomeningitis is associated with a limited spectrum of diseases. Meningitis does not seem to impact ocular and extraocular outcomes. Therefore, lumbar puncture should be performed on an individual basis during the diagnostic workup of uveitis.

Arthritis Res Ther 2021; 23:135.

Abstract
BACKGROUND Earlier, we reported that the microRNA (miR)-155 expression in dendritic cells (DCs) from Behcet's disease (BD) patients was decreased and affected cytokine production of DCs. In this study, we investigated the mechanisms whereby miR-155 regulates cytokine production by DCs. METHODS The formation of autophagosomes in DCs was detected by transmission electron microscopy. Western blotting was used to detect the protein levels of LC3, Beclin-1, P62, p-mTOR, and p-Akt in DCs. TNF-α, IL-6, and IL-1β expression were investigated by ELISA. MiR-155 mimics were transfected to DCs to evaluate its effects on autophagy and cytokine production. RNA interference was used to downregulate the expression of TAB2. RESULTS The formation of autophagosomes was found in DCs of active BD patients. The expressions of LC3-II, Beclin-1, and P62 were significantly increased in DCs of active BD patients compared to that of inactive BD patients and healthy controls. The expressions of IL-6, IL-1β, and TNF-α were significantly increased in DCs of active BD patients compared to that of healthy controls. The autophagy promoter (3-MA) and inhibitor (rapamycin) significantly decreased or increased the expression of TNF-α, IL-6, and IL-1β by DCs. The expression of LC3-II and Beclin-1 was significantly increased, but the expression of P62 proteins was decreased in DCs transfected with miR-155 mimics or after TAB2 was downregulated. The expression of TNF-α, IL-6, and IL-1β was decreased in DCs after miR-155 was upregulated or TAB2 was downregulated. The ratios of p-Akt/Akt and p-mTOR/mTOR were decreased in DCs after miR-155 was upregulated. CONCLUSIONS These results suggest that miR-155 affects the production of TNF-α, IL-6, and IL-1β by DCs through activation of the Akt/mTOR signaling pathway and by affecting the process of autophagy.

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
Purpose: To investigate the role of ultra-widefield fluorescein angiography (UWFA) for monitoring therapeutic response to adalimumab in patients with Behcet's uveitis.Methods: Patients with Behcet's uveitis treated with adalimumab for ≥30 weeks were included. Intraocular inflammation, best-corrected visual acuity, systemic medications, and UWFA scores were evaluated.Results: Thirty-eight eyes of 20 patients were included. Significant decreases in grading of anterior chamber cells and vitreous haze were observed at 6, 14, and 30 weeks after adalimumab administration (p < .001 for all). UWFA scores on vascular and capillary leakage were decreased at week 6 and further improved at weeks 14 and 30. Moreover, UWFA score further decreased at 14 and 30 weeks, even after manifest inflammation became quiescent at 6 weeks. (p = .004 and 0.001, respectively).Conclusion: UWFA scores significantly improved in Behcet's uveitis patients treated with adalimumab, and further improvement of UWFA scores was found in patients with a clinically quiescent inflammatory state.

Pharmaceutics 2021; 13:pharmaceutics13040476.

Abstract
This review aimed to investigate the efficacy of integrative medicine (herbal medicine combined with drug therapy) in the treatment of Behcet’s disease (BD). Eleven databases were searched from their inception to 7 December 2020, for randomized control trials (RCTs) that reported the effects of integrative medicine in treating BD. The risk of bias was assessed using seven domain criteria from the Cochrane Collaboration tool. Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to assess the quality of evidence. The direction of the effect is also shown in the form of an albatross plot. Sixteen trials met the inclusion criteria and were analyzed. The overall risk of bias was determined to be uncertain. The meta-analysis showed a superior response rate with herbal medicine plus drug therapy (relative risk (RR) 1.19, 95% confidence interval (CI) 1.13 to 1.25, n = 1034, p < 0.00001, I2 = 0%, low certainty of evidence (CoE)) compared to drug therapy. Integrative medicine also lowered the recurrence rate after 2 months of follow-up (RR 0.27, 95% CI 0.09 to 0.76, n = 120, p = 0.01, I2 = 0%, low CoE). The erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level, and skin lesions were also significantly improved using integrative medicine, but equivalent effects were seen for oral ulcers, genital ulcers, and eye inflammation. Minor adverse events were reported in both groups. Our findings suggest that herbal medicine combined with drug therapy is more effective for the treatment of BD than drug therapy alone. Although the type of drug therapy used varied across the studies, integrative medicine was shown to improve the total response rate, skin lesions, the ESR, and the CRP level. However, the overall risk of bias of the studies was concerning, and the CoE was low. Information on adverse events (AEs) was also insufficient. In addition, the number of studies included for data synthesis for most outcomes was small. Future studies with rigorous RCTs may help establish the efficacy of integrative medicine in the treatment of BD.

Abstract
Interleukin (IL)33, a member of the IL1 superfamily, functions as a nuclear factor and mediates biological effects by interacting with the ST2 receptor. Recent studies have described IL33 as an emerging pro-inflammatory cytokine in the immune system, and IL33/ST2 gene polymorphisms have been implicated in the pathogenesis of various immune diseases. However, the underlying mechanisms of IL33/ST2 in Behcet's disease (BD) remain to be defined. Here, we investigated the association between IL33/ST2 gene polymorphisms and BD in 585 BD uveitis (BDU) patients and 834 healthy controls using Agena MassARRAY iPLEX platform. We found that rs3821204 was associated with the development of BDU. Moreover, the frequency of rs2210463 G allele was lower in patients with genital involvement. Association analysis revealed a much greater genetic difference between complete-type and incomplete-type BD groups, including three SNPs (rs7044343, rs1048274, and rs2210463). Our findings suggest that IL33/ST2 gene polymorphisms are involved in the pathogenesis of BDU. Different genetic backgrounds may exist in complete-type and incomplete-type BD patients.

Abstract
Background Fibromuscular dysplasia (FMD) is a type of unexplained nonatherosclerotic vascular disease that usually involves the renal and internal carotid arteries and rarely involves the mesenteric artery. Mesenteric artery FMD is difficult to distinguish from Crohn’s disease (CD) and Behcet’s disease (BD) solely based on symptoms. Patients with mesenteric artery FMD can present with an acute abdomen, but case reports of patients who have a long medical history and undergo multiple bowel resections are extremely rare. Case presentation
The patient was a 45-year-old woman with an 11-year history of intermittent lower abdominal pain and fever. At the age of 34 years, she underwent right hemicolectomy and appendectomy due to an acute abdomen. She suffered from oral ulcers between 34 and 36 years old. A clinical diagnosis of presumed CD was made by the age of 41, and she was treated with mesalazine; however, the effect was poor. At the age of 42, she came to our centre, and based on her atypical symptoms and examination results, we thought she had CD. Hence, she was treated with glucocorticoids for 3 years. However, when she was 45, due to steroid dependence, thalidomide tablets were added. Unfortunately, she suffered from another episode of intestinal obstruction. Therefore, she underwent enterectomy. The postoperative histopathological diagnosis was mesenteric artery FMD. She no longer underwent pharmacotherapy after the surgery. Although she did not have any of her previous symptoms and postoperative colonoscopy showed no signs of recurrence, splenomegaly and abnormal routine blood results were still present. Conclusions Patients with mesenteric artery FMD can present with an acute abdomen. In addition, the symptoms and endoscopic manifestations of mesenteric artery FMD may appear similar to CD and BD. Hence, it is difficult to make a clear clinical diagnosis and proceed with treatment. Mesenteric artery FMD often requires surgical pathology to confirm its diagnosis. For patients who suffer from this disorder, surgery may be the best choice to improve the patient’s quality of life.
