Abstract
Behçet's disease is a chronic multisystem vasculitis of unknown etiology. The disease is commonly described in young adults but can occur in childhood. Diagnosis is based on clinical manifestations since there are no pathognomonic laboratory findings. Early diagnosis in children is challenging due to the insidious nature of the disease and the low sensitivity of adult criteria in the pediatric population. The purpose of this review is to describe the demographic and clinical features of Behçet's disease in childhood, its complications and recent advances in therapeutics highlighting differences with the adult onset disease.

Abstract
OBJECTIVE Gastrointestinal (GI) involvement in childhood Behçet disease (BD) is not well understood. We aimed to clarify the intestinal presentation in children with BD. METHODS Medical records of 85 children with recurrent oral ulcers between 1990 and 2010 at the National Taiwan University Hospital were reviewed retrospectively. Twenty of them who fulfilled the Mason and Barnes criteria for the diagnosis of childhood BD were enrolled. The clinical and laboratory characteristics were analyzed. RESULTS Among 20 patients, the median age at diagnosis was 13.2 years. The common presentations included oral ulcers (100%), genital ulcers (70%), skin lesions (65%), and GI symptoms (50%). Five of 10 patients with GI symptoms received endoscopic examinations and all had ulcers. Divided by the age of 10, patients younger than 10 years tended to have higher rates of GI symptoms initially and intestinal ulcers (P = 0.002 and 0.015, respectively). Platelet count was significantly lower in young patients (P = 0.0151). Patients without GI symptoms had higher rates of skin involvement than patients with GI symptoms (P = 0.019). CONCLUSIONS Young children with BD tended to have more GI presentations. For children with BD younger than 10 years having GI symptoms, endoscopic examinations may be considered.

Abstract
The diagnosis of Behçet disease is clinical and based on the presence of characteristic ocular and systemic inflammatory manifestations. Patients may present with anterior, posterior, or panuveitis in one or both eyes. The differential diagnosis includes a variety of infectious and noninfectious causes of acute nongranulomatous anterior uveitis, intermediate uveitis, occlusive retinal vasculitis, focal or multifocal retinitis, and necrotizing retinitis. A course characterized by sudden onset with improvement followed by recurrence of inflammatory signs is most typical for Behçet uveitis.

Abstract
A 51-year-old man was referred for body weight loss and lower right abdominal pain. Total colonoscopy revealed discrete and round ulceration at the ileocecal valve, and he was diagnosed with intestinal Behçet's disease (BD). By treatment with glucocorticoid, colchicine and salazosulfapyridine, the symptoms and ulceration were improved, but cessation of glucocorticoid resulted in relapse of ulceration at the terminal ileum. Long-term, low-dose treatment with clarithromycin (CAM) was implemented for chronic respiratory infections. Furthermore, we expected that this CAM treatment would also be effective in BD. During this long-term, low-dose treatment with CAM, discrete ulceration at the terminal ileum was never revealed by follow-up total colonoscopy once or twice per year for 7 years. No reports have described the effectiveness of this treatment in patients with intestinal BD; however, we confirm that long-term treatment with low-dose CAM might have clinical benefits for patients with intestinal BD.

Abstract
Behcet’s disease is a multisystem autoimmune disease with variable clinial manifestations. The diagnosis may pose a difficult challenge for the clinician, who has to be familiar with the wide spectrum and combination of the symptoms of Behcet’s disease. It is considered a rare disease in Hungary, and there are only few reports on Behcet’s disease in the Hungarian literature. However, the past history of Hungary, the worldwide growing incidence of the disease, and the authors’ experience raise the possibility that the occurrence of the disease is higher than previously thought. In this review the authors present and discuss literature data on the pathogenesis and pathomechanism, as well as their own experience concerning the symptomatology of Behcet’s disease in order to promote diagnosis and offer adequate therapy for the patients. The authors presume that the importance of the disease is underestimated in Hungary due to a considerable number of unrecognized cases and they propose to establish a national registry for Behcets disease.

Abstract
BACKGROUND Crohn's disease (CD) and intestinal Behcet's disease (BD) are transmural inflammatory diseases with fluctuating courses characterized by repeated episodes of relapse and remission that often require operation or reoperation. However, no study has directly compared the long-term prognoses of these two diseases. METHODS We reviewed the medical records of 332 patients with CD and 276 patients with intestinal BD who were regularly followed up at a single tertiary academic medical center in Korea between March 1986 and July 2010. The clinical outcomes after diagnosis and surgery were analyzed using the Kaplan-Meier method and log-rank test. RESULTS There were no significant differences in the cumulative probabilities of surgery (29.4% and 36.0% vs. 31.6% and 44.4% at 5 and 10 years, respectively: P = 0.287) or admission (66.1% and 73.8% vs. 59.0% and 69.2%, P = 0.259) between CD and intestinal BD. Furthermore, no differences were observed between the two diseases for the cumulative probabilities of postoperative clinical recurrence (P = 0.724) and reoperation (P = 0.770). However, the cumulative probabilities of corticosteroid use (63.8% and 76.6% vs. 42.6% and 59.4% at 5 and 10 years, respectively: P < 0.001) and immunosuppressant use (49.1% and 65.5% vs. 27.1% and 37.7%, P < 0.001) were significantly higher in CD patients than in intestinal BD patients. CONCLUSIONS There were no significant differences in the long-term clinical outcomes and postoperative prognoses between CD and intestinal BD, although CD patients required corticosteroid or immunosuppressant therapy more often than intestinal BD patients.

Abstract
Crohn's disease is a relapsing systemic inflammatory disease, mainly affecting the gastrointestinal tract with extraintestinal manifestations and associated immune disorders. Genome wide association studies identified susceptibility loci that--triggered by environmental factors--result in a disturbed innate (ie, disturbed intestinal barrier, Paneth cell dysfunction, endoplasmic reticulum stress, defective unfolded protein response and autophagy, impaired recognition of microbes by pattern recognition receptors, such as nucleotide binding domain and Toll like receptors on dendritic cells and macrophages) and adaptive (ie, imbalance of effector and regulatory T cells and cytokines, migration and retention of leukocytes) immune response towards a diminished diversity of commensal microbiota. We discuss the epidemiology, immunobiology, amd natural history of Crohn's disease; describe new treatment goals and risk stratification of patients; and provide an evidence based rational approach to diagnosis (ie, work-up algorithm, new imaging methods [ie, enhanced endoscopy, ultrasound, MRI and CT] and biomarkers), management, evolving therapeutic targets (ie, integrins, chemokine receptors, cell-based and stem-cell-based therapies), prevention, and surveillance.

Abstract
Behçet syndrome (also known as Behçet disease) is a rare condition that is associated with considerable morbidity. Cases of Behçet syndrome have been reported worldwide, but the highest prevalence occurs in countries that border the ancient Silk Route, such as Turkey and Iran. Although oral ulceration, genital ulceration and eye disease are the classic triad of manifestations, the cardiovascular, gastrointestinal, musculoskeletal and central nervous systems can also be affected. The syndrome is chronic and relapsing with some patients having benign episodes whereas others have more serious complications, including blindness or the rupture of a pulmonary arterial aneurysm. Diagnosing Behçet syndrome, particularly outside of endemic regions, often incurs a considerable delay owing to the rarity of this condition. Furthermore, a paucity exists of data from randomized controlled trials on the optimal therapeutic approaches to use in patients, as well as a lack of informative laboratory surrogate markers to monitor disease progression. This Review discusses the issues surrounding the diagnosis and differential diagnosis of Behçet syndrome and presents the current approaches to managing patients with this complex group of disorders.

Interactions between IL17A, IL23R, and STAT4 polymorphisms confer susceptibility to intestinal Behcet's disease in Korean population. Life Sci 2012; 90:740-6. [PMID: 22483685 DOI: 10.1016/j.lfs.2012.03.017] [Citation(s) in RCA: 50] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2011] [Revised: 03/06/2012] [Accepted: 03/16/2012] [Indexed: 02/06/2023]
Abstract
AIMS Although polymorphisms in IL23R have recently been proposed to predispose to Behcet's disease (BD), associations between IL23R polymorphisms and intestinal BD have yet to be elucidated. We therefore performed a study to evaluate whether IL17A, IL23R, and STAT4 polymorphisms are associated with susceptibility to intestinal BD in the Korean population. MAIN METHODS Single nucleotide polymorphisms (SNP) in the IL17A, IL23R, and STAT4 genes were analyzed using DNA sequencing, denaturing high performance liquid chromatography, and TaqMan genotyping assays. KEY FINDINGS Individual polymorphism analysis revealed that the TT genotype of IL17A rs8193036 (odds ratio (OR) 2.10, 95% confidence interval (CI) (1.12-3.92), p=0.021), and GG+GT genotype of IL23R rs1884444 (OR 1.92, 95% CI (1.03-3.57), p=0.034) was associated with the development of intestinal BD. When these two genotypes were combined, the risk of BD increased compared to that of patients with no-risk or one-risk genotype (OR 2.21, 95% CI (1.13-4.34), p=0.021). Furthermore, statistically significant gene-gene interactions were observed between G149R in IL23R vs. rs11685878 in STAT4, rs2275913 in IL17A vs. rs7574865 in STAT4, and rs11889341 in STAT4 vs. rs2275913 in IL17A. The haplotypes of IL17A had a positive association with intestinal BD risks, whereas those of IL23R were protective for disease development. SIGNIFICANCE Our results indicate that the interaction of specific IL17A, IL23R, and STAT4 SNPs modulate susceptibility to intestinal BD in the Korean population, suggesting that the IL-17/23 axis plays a significant role in disease pathogenesis.

Abstract
BACKGROUND There is no disease activity index (DAI) currently available that can objectively assess the disease status of intestinal Behçet's disease (BD). The aim of this study was to develop a novel specific DAI for intestinal BD through a prospective study. METHODS Items included in the index were produced and graded by experts in intestinal BD. Two separate cohorts of patients (weighting and validation cohorts) with intestinal BD were prospectively enrolled, and their clinical and laboratory data were collected. Through weighting items by multiple regression modeling, the DAI for intestinal BD (DAIBD) was derived using the weighting cohort and validated using the validation cohort. The index's responsiveness was evaluated using a longitudinal cohort derived from the weighting cohort at a follow-up visit 2-3 months later. RESULTS A total of 110 patients with intestinal BD were enrolled in the weighting cohort. Eight of the 17 items selected by the experts accounted for 86.8% of the physician's global assessment (PGA) variance. The DAIBD calculated with gradations of weighted items correlated more strongly with PGA (r=0.850) than did the Crohn's disease activity index (CDAI) (r=0.649) in 50 patients of the validation cohort. Furthermore, quiescent, mild, moderate, and severe could be discriminated using the best cutoff scores. The DAIBD showed much higher responsiveness than did the CDAI (r=0.812 vs. 0.645, respectively) in 109 patients in the longitudinal cohort. CONCLUSIONS This novel DAIBD is an easy, valid, and responsive index to assess disease activity and can be useful to physicians who treat intestinal BD.

Abstract
A 50-year-old woman with Beçhet's disease presented with episodic diarrhoea and generalised abdominal pain. She was on regular mycophenolate maintenance therapy, being intolerant of both ciclosporin and azathioprine. Previous rectal biopsy was consistent with colitis, probably associated with Beçhet's disease. During this admission, she began passing faecal matter per vaginam. Digital rectal examination confirmed the presence of a large rectovaginal fistula. She underwent urgent laparotomy for a subtotal colectomy with end ileostomy. Although there were no signs of septicaemia preoperatively, small perforations were identified in the caecum and at the splenic flexure on laparotomy. Histopathology confirmed the presence of multiple shallow ulcers throughout the colon with features suggestive of Beçhet's colitis.

Abstract
PURPOSE Intestinal Behçet's disease (BD) is challenging to diagnose, especially if the patient presents with typical colonoscopic findings of intestinal BD without systemic manifestations of BD. We performed this study to evaluate the systemic manifestations of BD in patients with typical colonoscopic findings of intestinal BD at the time of initial presentation and to identity the chronologic changes of these features during an extended follow-up period. METHODS One hundred twenty-six consecutive patients who showed typical colonoscopic findings of intestinal BD at a single institution in Korea were enrolled. Clinical and endoscopic data were collected from a medical database and using a written questionnaire. Parameters including demographic characteristics and the subset type of BD at the initial and endpoints of the follow-up were analyzed. RESULTS The mean follow-up period was 63.9 ± 50.9 months. The number of cases that satisfied the International Study Group for Behçet's Disease criteria at initial diagnosis, 19.0%, increased to 53.2% by the end of follow-up. When the Japanese criteria were used for classification, the proportion of complete and incomplete type BD increased (2.4% and 26.2% to 18.3% and 49.2%, respectively), while that of suspected and not-satisfied subtype BD decreased (22.2% and 49.2% to 19.0% and 13.5%, respectively) during the follow-up period. CONCLUSIONS Our data suggest that patients who lack the systemic manifestations of BD could be included in the category of intestinal BD when typical intestinal lesion is identified, indicating that close examination and early treatment should be considered in such patients.

Abstract
BACKGROUND Gastrointestinal tract involvement in Behçet's disease (BD) often requires surgical intervention due to serious complications such as intestinal perforation, fistula formation, or massive bleeding. AIM The aims of this study were to investigate the clinical and surgical features of free bowel perforation and to determine the risk factors associated with this complication in intestinal BD patients. METHODS We reviewed the medical records of 129 patients with intestinal BD treated from September 1988 to September 2008. Among them, 33 patients had intestinal perforations and all underwent emergent or elective laparotomy. RESULTS The mean age of the patients with bowel perforation was 34.8 ± 15.6 years (range 12-70 years) with a sex ratio of 2.3:1 (male:female). Twenty-seven (81.8%) patients were diagnosed with intestinal BD preoperatively, whereas six (18.2%) patients were diagnosed by pathological examination after operation. Fourteen (42.4%) patients experienced postoperative recurrence of intestinal BD and 11 (33.3%) underwent reoperation. Multivariate Cox hazard regression analysis identified younger age (≤ 25 years) at diagnosis (HR = 3.25; 95% CI, 1.41-7.48, p = 0.006), history of prior laparotomy (HR = 5.53; 95% CI, 2.25-13.56, p = 0.0001), and volcano-shaped intestinal ulcers (HR = 2.84; 95% CI, 1.14-7.08, p = 0.025) as independent risk factors for free bowel perforation in intestinal BD. CONCLUSIONS According to the results of our study, patients diagnosed with intestinal BD younger than 25 years, who had a history of prior laparotomy or volcano-shaped intestinal ulcers have an increased risk of free bowel perforation.

Abstract
Inflammatory bowel disease (IBD) describes chronic inflammatory disease of the intestines and has a variable course; Crohn's disease and ulcerative colitis comprise the two main forms of the condition. Although IBD occurs worldwide, its epidemiologic and clinical characteristics vary depending upon the geographic location and the ethnicity of the population. Identifying the characteristic features of IBD in populations living in different geographical locations and with different ethnicities may provide significant clues about its etiology and pathophysiology, which in turn may be helpful in the development of more appropriate treatment strategies for IBD for these different populations. Therefore, it is important for each country and region to evaluate critically the epidemiology, genomics, and clinical characteristics of IBD among its own population. We have performed a critical review of the recent data in Korea, and describe herein the current epidemiologic and genotypic status, as well as the clinical manifestations and therapeutic responses of IBD that are unique to Korean patients.

Abstract
OBJECTIVES It is difficult to diagnose intestinal Behçet's disease (BD) due to various extraintestinal manifestations emerging at different time points in the disease course and a lack of reliable diagnostic criteria. We conducted this study to develop and validate novel diagnostic criteria for intestinal BD. METHODS Experts from three universities generated the preliminary diagnostic criteria for intestinal BD, and a consensus was reached using a modified Delphi method with 13 gastroenterologists participating. To validate the criteria, we recruited 12,850 consecutive patients who underwent colonoscopic examinations between January 2000 and December 2006 at Severance Hospital, Yonsei University, Seoul, Korea. RESULTS The novel diagnostic criteria were developed on the basis of two aspects: colonoscopic findings and extraintestinal manifestations. Of the 12,850 patients, 280 with ileocolonic ulcers were enrolled for validation. At the time of initial colonoscopic examinations, patients were categorized for BD status into 4 groups: definite (84 patients), probable (67), suspected (15), and nondiagnostic (114). At the end of the follow-up period (mean, 50.9+/-25.7 months), intestinal BD was confirmed in 145 patients (51.8%)-84 (100%) from the definite group, 49 (73.1%) from the probable group, 10 (66.7%) from the suspected group, and 2 (1.8%) from the nondiagnostic group. The overall sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the diagnosis probability of these criteria were 98.6, 83.0, 86.1, 98.2, and 91.1%, respectively. CONCLUSIONS These newly proposed, simple criteria might be useful in diagnosing intestinal BD, especially in patients with ileocolonic ulcers who do not fully satisfy the diagnostic criteria of systemic BD.

Abstract
Endoscopy plays a key role in the diagnosis and treatment in inflammatory bowel disease (IBD). The most valuable tool for distinguishing different types of IBD is a complete ileocolonoscopy with mucosal biopsy. Endoscopic localization of the disease not only aids in determining prognosis and appropriateness of medical therapies but also aids decision-making in those undergoing surgical therapy. With regard to therapeutic applications, obstructive symptoms caused by benign fibrotic strictures can be treated adequately by endoscopic balloon dilation. Epidemiological studies have demonstrated an increased risk of colorectal cancer in patients with both ulcerative colitis and colonic Crohn's disease (CD). Colonoscopy is currently considered to be the gold standard for cancer surveillance. Published guidelines recommend that two to four biopsy samples should be obtained every 10 cm in the colorectum, necessitating 20-50 samplings per examination. This may result in standard colonoscopy - which is also very time-consuming and laborious - missing significant numbers of small lesions. Various novel techniques have been applied to reduce the required number of biopsy samples and the duration of examinations, including chromoendoscopy with or without magnification, fluorescence endoscopy, narrow-band imaging, optical coherence tomography, and confocal laser endomicroscopy. Until recently the only way to evaluate the small-bowel mucosa in a patient with CD was by barium small-bowel radiographs and intubation of the distal terminal ileum. Both wireless-capsule endoscopy (WCE) and double-balloon enteroscopy (DBE) allow light to be used in the inspection of the small bowel and may replace radiological methods. WCE is more convenient than DBE for probing small-bowel mucosal changes, but only DBE allows a biopsy sample to be obtained from the deep small bowel, and these two examinations can be considered complementary. The wider application of new techniques in the near future might increase the role played by endoscopy in the management of IBD.
