Clinical characteristics of Behçet's syndrome in Shanghai database: Baseline data of a cross-sectional cohort study.

OBJECTIVE: Behçet's syndrome (BS) is a variant vessel vasculitis that can involve multiple organs, with highly heterogeneous clinical manifestations. This study aims to analyze baseline data of BS patients to enhance the comprehension of its clinical features. METHODS: This study included 1216 registered cases of BS patients referred to Huadong Hospital affiliated with Fudan University. Each patient was thoroughly assessed and recorded for demographic data, clinical manifestations, gastrointestinal endoscope, imaging, etc. RESULTS: Significant gender differences were observed in clinical manifestations. Pseudofolliculitis (p < .001), uveitis (p = .003), vascular (p < .001), and cardiovascular involvement (p < .001) were significantly more prevalent in male BS patients, while genital ulcers (p = .011) and erythema nodosum (p = .009) were more common among the female. Furthermore, pseudofolliculitis (44.3%, 37.4% vs. 25.0%, p < .001), pathergy test positivity (37.0%, 24.5% vs. 12.6%, p < .001), and uveitis (18.8%, 18.4% vs. 11.2%, p < .001) showed higher incidence rates in the 16-35 years age group. Vascular involvement (11.1%, 18.0% vs. 15.8%, p < .001) notably increased in the 36-50 years age group. Additionally, the ISG diagnostic criteria were more likely to be met in the 16-35 age group (OR: 2.039, 95% CI: 1.581-2.631, p < .001), whereas the ICBD criteria were less likely to be met in the 16-35 age group (OR: 0.266, 95% CI: 0.150-0.474, p < .001). CONCLUSIONS: This study provided data on the baseline of clinical features of BS in a single center, BS patients presented significant heterogeneity, showing different manifestations across various genders and age groups. This diversity might contribute to a better understanding of BS clinical features and pave the way for future multi-center studies.

Challenges and opportunities in transitional care process in Behçet's syndrome.

Behçet's syndrome (BS) is a rare chronic multi-systemic inflammatory disorder that usually involves adults between third and fourth decades of life, while pediatric and juvenile onset are relatively rare. BS young patients (YP) often develop a full-blown disease late after onset, requiring careful diagnostic workup and regular follow-up while they grow up. In this regard, the purpose of transitional programs is to ensure continuous high-quality care to YP with chronic conditions, providing them with the skills necessary to become independent and empowered adults able to chronically self-manage their disease. EULAR/PReS released the first set of standards and recommendations for transitional care (TC) of YP with juvenile-onset rheumatic diseases, but the appropriate timing for transition, the tools to evaluate patients' readiness, and indicators of transition plans effectiveness still need to be identified. Although little is known regarding TC in BS, it is easy to assume that BS YP will benefit from developmentally and disease-specifically appropriate transition plans, which may promote continuity of care, improve perceived quality of life and prevent poor disease outcomes. This perspective article discusses the key concepts and the goals of TC, addressing the potential challenges and opportunities of TC for YP with BS in clinical practice.

Association between Behçet's disease and apical periodontitis: A cross-sectional study.

BACKGROUND: The correlation between Behçet's disease (BD) and apical periodontitis (AP) has not been investigated. OBJECTIVES: The aim of the study was to evaluate the association between BD and AP using different variables. MATERIAL AND METHODS: A total of 98 individuals (49 with BD and 49 controls) were recruited for the study. The presence of AP was confirmed through radiographic and clinical examination in all patients. The following data was evaluated in both the BD group and the control group: the presence of teeth with AP; the presence of root canal-treated (RCT) teeth; the presence of RCT teeth with AP; the severity of the disease; the types of medication taken; and the duration of the disease. The χ2 test and the logistic regression analysis were performed to ascertain the association between BD and AP. RESULTS: A total of 32 patients in the BD group and 12 patients in the control group presented with AP. The prevalence of teeth with AP was significantly higher in the BD group than in the control group (odds ratio = 5.804, p < 0.05). The χ2 analysis demonstrated a statistically significant association between AP and both gender and BD activity (p < 0.05). Furthermore, the logistic regression analysis indicated that the severity of the disease was a predictor of BD (p < 0.05). CONCLUSIONS: A significantly higher prevalence of AP was observed in patients with BD. However, the success rate of endodontic treatment in patients with BD was comparable to that observed in healthy individuals.

Mimickers of nervous system involvement among patients with Behçet's syndrome.

OBJECTIVES: We aimed to identify conditions mimicking nervous system involvement among patients with Behçet's syndrome (BS) and to determine clinical, laboratory and imaging findings that may help in the differential diagnosis. METHODS: We screened the charts of 500 consecutive BS patients to identify those who were referred to neurology at any time during their follow-up. The final diagnoses, presenting signs and symptoms, laboratory and imaging results were retrieved from patient charts. Patients who did not have a follow-up visit during the last 3 months were invited to the clinic. RESULTS: Among the 500 BS patients, 116 (23%) had been referred to neurology. Among these, 29 (5.8%) were diagnosed with typical central nervous system involvement of BS (NeuroBS). The type of NeuroBS was parenchymal involvement in 21 patients, cerebral venous sinus thrombosis in 7 patients, and both in 1 patient. 30 patients (6%) had other conditions related to the nervous system, 46 (9.2%) did not have a nervous system disorder, and their symptoms recovered spontaneously, and 11 (2.2%) were lost to follow-up without a definite diagnosis. Of the 30 BS patients who were diagnosed with another nervous system condition, 14 (46%) had primary headache syndromes, 6 (20%) had psychiatric disorders, 2 had entrapment neuropathy, and 1 each had epilepsy, glial tumor, multiple sclerosis, Meniere's disease, optic neuritis, neuroretinitis, steroid myopathy and polyneuropathy. CONCLUSION: Nervous system conditions other than NeuroBS are frequent among BS patients referred to neurology. Caution is required to avoid misdiagnosis of these patients as NeuroBS.

Behçet's Syndrome in a Child: A Case Report and a Review of Literature.

Behçet's syndrome is a complex chronic inflammatory disorder characterized by widespread inflammation of the blood vessels, affecting various systems in the body. Although its exact cause remains unknown, genetic predisposition, particularly HLA-B51/B5 gene carriage, and environmental factors are believed to play roles. The disease typically manifests in individuals aged 20-40 years, with an uncommon occurrence in children and elderly individuals. Key clinical manifestations include recurrent oral and genital ulcers, skin lesions, ocular involvement, positive pathergy test results, and other systemic symptoms. Eye involvement is common and can lead to severe visual impairment if left untreated. This diversity of Behçet's disease (BD) presentations and complications emphasizes the importance of early recognition and management. An eight-year-old girl presented with a deep painful ulcer in the mouth and a history of chronic constipation, severe joint pain, and recurrent mouth ulcers. Initial examination revealed an ulcer scar on the tongue and a deep ulcer on the left side of the mucobuccal fold. The patient was diagnosed with a recurrent major aphthous ulcer and prescribed Predo pediatric syrup as a mouthwash and paracetamol to relieve the pain. A biopsy was recommended by her physician to be done under general anesthesia and to rule out malignancy; the biopsy result revealed the presence of a benign squamous epithelium with reactive changes. The genetic result revealed HLA B*51 positivity and normal immunoglobulin levels. Treatment with colchicine led to the complete healing of the ulcer with scar formation after three months. This case report highlights the unique presentation of Behçet's syndrome in children and the challenges associated with its diagnosis. It emphasizes the importance of the early recognition and prompt management of BD in the pediatric population, in which disease progression can be more severe than in adult-onset cases. This case provides valuable insights into the clinical features of and diagnostic approach to Behçet's syndrome in children.

Behçet's Syndrome With Multiple Bilateral Pulmonary Aneurysms Associated With Endomyocardial Fibrosis Presented With Pulmonary Emboli: A Case Report.

Behçet's syndrome (BS) is a rare chronic multisystemic inflammatory disorder of unknown etiopathogenesis. BS is classified as a vasculitis of variable vessel size, which can manifest in both arterial and venous blood vessels. BS commonly presents with mucocutaneous and ocular manifestations. Superficial and deep vein thrombosis is present in 50% of patients, with atypical venous thrombosis affecting the inferior vena cava, superior vena cava, hepatic veins with Budd-Chiari syndrome, portal vein, cerebral sinuses, and right atrium and ventricle. Arterial manifestations include in situ thrombosis, pulmonary artery aneurysms, aneurysms of the abdominal aorta, and aneurysms of visceral and peripheral arteries. This article reports a new case of BS in a 28-year-old female patient who presented with severe dyspnea and hemoptysis. Echocardiography and cardiovascular magnetic resonance imaging led to the diagnosis of endomyocardial fibrosis and a large right ventricular thrombus with pulmonary embolism. Computed tomography angiography revealed multiple pulmonary aneurysms and emboli. Rare findings such as endomyocardial fibrosis and Budd-Chiari syndrome were noted. This case highlights the role of medical imaging modalities in diagnosing rare syndromes such as BS, as demonstrated in the current case.

Long-term outcomes of infliximab treatment in neuro-Behcet syndrome: A single-center retrospective study.

INTRODUCTION: Behcet's syndrome is a rare inflammatory disorder characterized by oral and genital ulcers, skin lesions, and uveitis. It exhibits a higher prevalence along the historic Silk Road. Neuro-Behcet syndrome (NBS) affects the central nervous system and poses significant morbidity and mortality risks. Infliximab, a TNF-alpha antagonist, has shown potential in NBS management, although the current evidence is mainly derived from case series due to the lack of randomized controlled trials. OBJECTIVE: This retrospective study aimed to evaluate the disease outcomes during the first and second years following infliximab treatment in NBS patients experiencing attacks despite prior conventional immunosuppressive therapy. The study also sought to investigate the safety profile and adverse effects associated with infliximab. METHODS: Fifty-three NBS patients were examined, with 22 receiving infliximab as either monotherapy or in combination with other therapies. Retrospective analysis was conducted on demographic data, clinical characteristics, and treatment responses. Treatment efficacy was measured using the Expanded Disability Status Scale (EDSS) modified for NBS. The study adhered to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist guidelines. RESULTS: Among the study cohort, 60.4% had parenchymal NBS, and 39.6% had nonparenchymal NBS. Treatment with infliximab resulted in remission or disease stabilization in 95% of patients after one year and 68.7% after 2 years. Relapse rates were 4.5% at 1 year and 18.7% at 2 years, with disease progression observed in two cases. Adverse effects were primarily mild to moderate, with no reports of serious adverse events. CONCLUSION: Infliximab exhibited efficacy in achieving remission or stabilization in NBS patients, maintaining a favorable safety profile. The timing of infliximab treatment may prevent the accumulation of disability and hinder disease progression. Nonetheless, future prospective studies are necessary to confirm these findings and refine treatment strategies for this complex condition.

Sexual dysfunction among female patients with rheumatic diseases.

To demonstrate the burden of sexual dysfunction (SD) among females with rheumatic diseases, we conducted a cross-sectional comparative study in patients with systemic sclerosis (SSc), systemic lupus erythematosus (SLE), and Behçet's syndrome (BS) along with suitable healthy controls (HCs). Age-matched female patients with SSc (n = 50), SLE (n = 49), and BS (n = 54), along with 52 female HCs were included in this study between April and October, 2021. Sociodemographic features were recorded, and psychometric tests, i.e., female sexual function index (FSFI), Beck depression inventory (BDI), body cathexis scale, and marital adjustment test (MAT) were performed. Scale scores were compared, and binary logistic regression was used to identify predictors for SD in the whole group. The total FSFI and body cathexis scores among the patient groups were significantly lower than those of the HCs (p < 0.001). Depression was significantly more frequent in the patient groups. MAT scores did not differ significantly between the study groups. Patients with SSc had the worst scores in each psychometric index, including MAT. Decreased body cathexis score [OR 0.974, 95% CI (0.957-0.991), p = 0.003] and low MAT score [OR 0.937, 95% CI (0.896-0.980), p = 0.005], and being diagnosed with SSc [OR 6.6, 95% CI (1.975-22.498), p = 0.002], SLE [OR 2.7, 95% CI (0.998-7.753), p = 0.050], and BS [OR 2.8, 95% CI (1.100-7.359), p = 0.031], were identified as independent predictors for SD. Body cathexis seems to be the most important independent predictor for SD, and the burden of SD appears heavier in patients with SSc, probably due to poor body image satisfaction.

Screening for familial disease presence in first-degree relatives of Behçet's disease patients: Is measurement of common femoral vein wall thickness valuable for the diagnosis?

OBJECTIVES: We aimed to assess first degree relatives (FDRs) of BD patients for the presence of clinical symptoms and signs of BD and evaluate common femoral vein (CFV) wall thickness measurement for the diagnosis. METHODS: Patients with BD(n=129) and FDRs(n=230) of these patients were included. FDRs were questioned in terms of BD symptoms by phone. Pathergy test and CFV wall thickness measurement were performed among 111 FDRs who accepted the clinical assessment. Clinical assessment group were classified according to the criteria sets for BD. FDRs who did not meet the criteria sets and had at least one clinical finding in addition to oral aphthae(OA) were categorized as the "suspected BD". RESULTS: :We observed increased frequency of isolated BD manifestations in FDRs. Ten FDRs were diagnosed with BD during clinical evaluation. Significantly increased CFV wall thickness was observed in FDRs of BD patients fulfilling diagnostic BD criteria (p<0.001 for both sides) and also in those with suspected BD group (p<0.05 for both sides). Presence of OA, genital ulcer, folliculitis or erythema nodosum were associated with increased CFV wall thickness (p<0.05). CONCLUSION: . Our results suggest that CFV wall thickness measurement can be used in diagnosis of familial BD.

De novo manifestations during adalimumab treatment in Behçet's syndrome.

OBJECTIVES: Treatment response may be variable across organ manifestations of Behçet syndrome (BS). We aimed to determine the frequency of de novo manifestations during adalimumab treatment. METHODS: We conducted a chart review of all BS patients who received adalimumab in our center between 2008 and 2023. Demographic data, reasons for initiating adalimumab, concurrent medications, previous treatments, and outcomes were recorded. We defined de novo manifestations as new BS manifestations that occurred for the first time during treatment with adalimumab. For patients with vascular involvement, a new vascular event at another vessel was also considered as a de novo manifestation. RESULTS: Among the 335 patients, a de novo manifestation developed in 14 (4%) patients. De novo manifestations were vascular involvement in 5 patients, arthritis in 3, anterior uveitis in 2, nervous system involvement in 2, gastrointestinal involvement in 1, and epididymitis in 1 patient. The primary reasons for adalimumab treatment were vascular involvement in 5 patients, uveitis in 4, arthritis in 3, mucocutaneous involvement in 1, and epididymitis in 1 patient. Upon the development of de novo manifestation, adalimumab was switched to another biologic in 4 patients, dose was intensified in 3, colchicine, conventional immunosuppressives, and/or glucocorticoids were added in 5, and topical eye drops were added in 2 patients, leading to remission of de novo manifestations in all patients. CONCLUSION: De novo manifestations were infrequent (4%) among BS patients treated with adalimumab. Of these, 57% were major organ involvement, mainly vascular involvement. None of the patients developed posterior uveitis.

Fever, Leukocytosis, and Ulcerated Vulvar Lesions: An Atypical Presentation Concerning Behcet's Disease.

Behcet's disease (BD) is a variable-vessel vasculitis commonly presenting in early adulthood with painful oral aphthous ulcers, genital ulcers, uveitis, pathergy, and skin lesions. The diagnosis of BD is made clinically based on criteria from the International Study Group (ISG) and the International Criteria for Behcet's Disease (ICBD). Due to the wide constellation of symptoms BD can cause, it can be challenging to diagnose in an acute setting. Here, we discuss a patient who presented with a clinical picture of sepsis, with profound ulcerated vulvar and herpetiform oral mucosal lesions, that led us to a presumptive diagnosis of Behcet's disease.

Profile of immunological biomarkers in Behcet's syndrome: a large-scale single-center real-world study.

Behcet's syndrome (BS) is a vasculitis characterized by immune dysregulation. Biomarkers are valuable for assessing clinically atypical pathogenesis. We aimed to investigate the distribution of different biomarkers and their effects on the clinical features of patients with BS in a large-scale, real-world study. This is a retrospective, single-center study. In total, 502 patients diagnosed with BS were enrolled in this study. We analyzed the clinical features of this cohort and divided patients' symptoms into six categories, including mucocutaneous, articular, neurological, gastrointestinal, vascular, and ocular involvements. HLA-B51 cells, autoantibodies, and subsets of immune cells from the patients were tested. Pearson's correlation, Wilcoxon rank sum test and multivariate logistic regression were used for data analysis. Various autoantibodies were detected in the serum of 40.8% of patients with BS. The positivity rate of anti-endothelial cell antibodies (AECA) was the highest among autoantibodies and was found in 23.5% (118/502) of patients with BS. The positivity rate of HLA-B51 in patients with BS was 27.1%. Tumor necrosis factor (TNF)-α, IL-2, and IL-4 producing CD4+ T cells were positively correlated with the gastrointestinal BS. Increased IL-4+CD4+ T cell was a risk factor for gastrointestinal BS (P = 0.006, Overall rate [OR] = 2.491, 95% Confidence interval [CI]: [1.317, 5.100]). Various autoantibodies can be detected in patients with BS. HLA-B51 and AECA are the most common biomarkers. Increased IL-4+ CD4+ T cell was a risk factor for gastrointestinal involvement in BS.

Neuro-Behçet's Syndrome Without Genital Ulcers: A Case Report and Literature Review.

Behçet's disease is a rare multisystemic vasculitis characterized by oral ulcers, genital ulcers, and skin and ocular lesions. Neuro-Behçet's syndrome is a condition in which individuals with Behçet's disease experience neurological symptoms that cannot be attributed to other neurological diseases. We present a rare case of neuro-Behçet's syndrome with acute internuclear ophthalmoplegia and deteriorating neurological function with a prior history of recurrent oral ulcers with pathergy-like features, acneiform papulopustular rash, retinal hemorrhages, and recurrent epididymitis without genital ulcers. Patient improved with cyclophosphamide. This case underscores the importance of diagnosing and managing neuro-Behçet's syndrome in the absence of genital ulcers.

Treatment of Behçet Uveitis in Türkiye.

Objectives: Behçet uveitis (BU) is a potentially blinding disorder. The main determinant of visual prognosis is early and appropriate treatment that provides rapid suppression of inflammatory attacks, control of subclinical inflammation, and prevention of new attacks. Our study aimed to determine the Turkish uveitis specialists' approach regarding the treatment choices and management of special situations such as pregnancy, vaccination, and surgical planning in BU patients, and to increase information sharing and raise awareness of issues where knowledge is lacking. Materials and Methods: A web-based survey including 16 questions about the treatment approach in ocular involvement of Behçet's disease was sent via e-mail to uveitis specialists in Türkiye. Based on the answers of 49 ophthalmologists who responded to the survey, we evaluated the approaches of uveitis specialists in our country to initiating treatment, selecting therapeutic agents, monitoring, switching and stopping treatment, and special situations such as surgical planning, vaccination, and pregnancy in BU patients. Results: Uveitis specialists in our country mostly act in accordance with the guidelines in the decision to start treatment, selection of therapeutic agents, and monitoring the safety of treatment in BU. However, there is a lack of information about the therapeutic approach in pregnancy and vaccination practices. It was also observed that there is no consensus on the precautions to be taken before cataract surgery. Conclusion: Our study has shown that there is a need for more detailed and widespread information sharing on treatment in preparation for ocular surgery, safety monitoring, drug use during pregnancy, and vaccination in BU patients.

Cardiovascular Manifestations in Behçet's Disease.

Cardiovascular involvement in Behçet's disease (BD) is considerably related to morbidity and mortality. However, the cardiovascular manifestation is sometimes difficult to distinguish from those of other causes. The suspicion of BD and proper treatment is pivotal in the management of BD. Histology demonstrates perivasculitis. Neutrophil seems to play an important role in the inflammation of BD. It is thought that inflammation causes venous thrombosis and arterial aneurysm. Characteristically, BD involves both arteries and veins of variable size in any region. Venous thrombosis needs immunosuppression, and inferior vena cava thrombosis and Budd-Chiari syndrome require intensive immunosuppressive therapy. Arterial involvement causes aneurysm which usually is treated by surgical or endovascular intervention with immunosuppression. Pulmonary artery aneurysm and cardiac involvement require multimodal managements.

HLA-B5 prevalence in patients with spondyloarthritis and impact on disease phenotype: a multicentric case-control study.

OBJECTIVE: The study aimed to estimate the prevalence of HLA-B51 and HLA-B52 in Lebanese patients with spondyloarthritis (SpA) compared to healthy controls (HC). We further aimed to evaluate the impact of HLA-B51 on phenotype and identify the distribution of the alleles in the HLA-B locus. METHODS: A case-control study enrolled consecutive SpA patients from three rheumatology clinics in Lebanon, including axial (axSpA), peripheral SpA (pSpA), and psoriatic arthritis (PsA) and HC from blood donors. Demographic and disease data were collected through interviews and file reviews, with testing of the entire HLA-B locus using molecular techniques. The prevalence of HLA-B51 and B52 was estimated in SpA patients versus controls. Prevalence comparisons were made, and logistic regression identified factors associated with HLA-B51 in patients. RESULTS: Data from 120 HC and 86 SpA patients (65 axSpA, 15 pSpA, 6 PsA), mean age 25.6 and 46.4 years, respectively, showed a higher HLA-B51 prevalence in SpA (25.6%), especially axSpA (29.2%) versus HC (12.5%), p = 0.016, and a numerically higher HLA-B52 prevalence (8.1% versus 4.2%, p = 0.230). HLA-B51 correlated with recurrent oral ulcerations (OR 7.99(95%CI 2.14-29.84) and radiographic juxta-articular erosions (OR 7.65(95%CI 1.14-38.03)). HLA-B35 was the most dominant allele in both groups (18.7%), followed by HLA-B27 (15.7%) and HLA-B51 (13.4%) in SpA. CONCLUSION: HLA-B51 was identified more frequently in patients with SpA compared to HC and was associated with recurrent oral ulcerations and juxta-articular radiographic erosions. Longitudinal studies are needed to determine whether this association indicates a disease overlap or might correlate with a specific SpA phenotype.

Corticosteroid-free adalimumab-cyclophosphamide combination therapy for acute phase neuro-Behçet's disease: a case report.

Neuro-Behçet's disease (NBD) represents a significant complication of Behçet's syndrome, potentially leading to elevated mortality and disability rates. The standard treatment for parenchymal NBD typically entails administering high-dose corticosteroids to prompt rapid-onset effects, coupled with immunosuppressants to prevent subsequent relapses. A 48-year-old male with NBD presented with progressively worsening dysarthria over 9 months. This patient experienced increased intraocular pressure while using glucocorticoids, which worsened his pre-existing glaucoma. The patient had a prior diagnosis of NBD and presented with progressive dysarthria over a period of nine months, leading to a brain magnetic resonance imaging (MRI) scan. The brain MRI revealed multifocal punctate high signal intensities in the left frontoparietal area, insula, and basal ganglia. Instead of the standard steroid pulse therapy, the patient received adalimumab-cyclophosphamide combination as an alternative induction therapy. Subsequent serial brain MRI scans exhibited no emergence of new lesions, and the patient remained devoid of clinical relapses even after 17 months from the commencement of induction treatment. Adalimumab-cyclophosphamide combination could be used as a corticosteroid-free induction strategy for NBD. Further investigations are warranted to establish the most suitable combination regimen.

Development of Posterior Uveitis in Behçet Syndrome Patients with Vitreous Cells at Baseline.

PURPOSE: The prognostic importance of vitreous cells (VC) in patients with Behçet syndrome (BS) is unknown. We aimed to determine the frequency of developing posterior uveitis (PU) and any additional risk factors associated with the development of PU in BS patients with VC at diagnosis. METHODS: The charts of 572 consecutive BS patients who were registered between 2010 and 2012 were reviewed. Among the patients with a follow-up of ≥2 years, we included 110 patients with VC in one or both eyes and 147 patients without any eye findings in both eyes at baseline and compared them for the development of PU. RESULTS: Among the 110 included patients with VC, 61 had VC in both eyes, 34 had VC in only one eye, and 15 had VC in one eye and PU in the other eye. There was anterior uveitis (AU) in addition to VC in the same eye in 13 patients at baseline. PU developed in 24 (22%) of these patients during a mean follow-up of 1.9 ± 1.1 years. This was significantly more frequent than the 147 patients without any eye findings at baseline, among whom there were only 2 patients who developed PU (p < 0.001). Multivariate logistic regression analysis showed that having AU in addition to VC in the same eye (OR, 5.03, 95% CI; 1.37-18.47) was an independent risk factor for the development of PU in patients with VC. CONCLUSION: Careful follow-up is required for patients with VC at diagnosis, since 22% developed PU within 2 years.

Impact of celiac disease in Behçet's syndrome patients: a study based on the database of Türkiye.

Background/aim: Our primary aim was to investigate the effects of concomitant celiac disease (CD) on the clinical characteristics of Behçet's syndrome (BS) patients. Materials and method: The study was a retrospective, nationwide, multicenter study. Turkish Ministry of Health National Electronic Database (e-Nabiz) is used under Health Ministry's supervision to extract the subject's data. Statistical analysis: Statistical analyses were made by the Statistical Package for Social Sciences (SPSS) software version 20 (IBM Corp., Armonk, New York). Continuous variables were presented by mean ± standard derivation (SD) or median (min-max) according to normality and compared by student-t test. A binary logistic regression analysis was performed to further investigating the relation between having a concomitant CD with each BD manifestation and comorbidity, frequencies of which were detected to be significantly different in the student-test. Results: A total of 84,241 patients diagnosed with BS were analyzed, and CD was identified in 175 (0.21 %) patients. The group with CD had a mean age of 41.30 ± 13.69 which was significantly younger. the prevalence of females was significantly higher (71.4%). The mean age of first admission for BS was also significantly younger in the group with CD (36.64 ± 13.28). BS patients with CD had a significantly higher prevalence of inflammatory bowel disease (27.2% vs. 7.3%, p < 0.001). When comorbid conditions were investigated depression (35.4% vs. 23.3%, p < 0.001), migraine (7.4 % vs. 2.6%, p < 0.001), fibromyalgia (10.9% vs. 4.5%, p < 0.001) and osteoporosis (12.6% vs. 6.6%, p = 0.001) were significantly more frequent in BS patients with CD. Conclusion: Our results suggest coexistence of CD in BS patients is related to female dominance and probably to an earlier disease onset. Several CD-related comorbidities as well as inflammatory bowel disease were more frequent in the CD group which implied an increased overall disease burden.
