Retinal thickness profiles in patients with Behçet uveitis during remission / Perfis de espessura da retina em pacientes com uveíte de Behçet durante remissão

ABSTRACT Purpose: The purpose of this study was to evaluate the intraretinal layer thickness in the macular region and its correlation with the duration of uveitis and visual acuity in patients with Behçet uveitis. Methods: In this cross-sectional study, we included 93 eyes of 57 patients with Behçet uveitis and 100 eyes of 50 healthy individuals admitted to a tertiary center from January to September 2017. We performed macular measurements in all subjects via spectral domain-optical coherence tomography (SD-OCT) and divided the retina into layers using automated segmentation software on the SD-OCT device. We then compared layer thicknesses between the patient and control groups and evaluated the correlation between OCT parameters and the duration of uveitis and visual acuity in the patient group. Results: Our records show a mean age of 37.9 ± 10.8 (18-64) years and 37.7 ± 12.2 (21-61) years in the patient and control groups (p=0.821), respectively. Meanwhile, data reveal a mean duration of uveitis of 6.9 ± 4.7 (1-20) years. We found a reduction in the total outer layer thickness in the patient group (p<0.001). However, we did not find a statistically significant difference in the inner retinal layers except in the inner nuclear layer. The duration of uveitis negatively correlated with the outer retinal layer's thickness (correlation coefficient = -0.250). On the other hand, visual acuity positively correlated with the central macular, the total inner layer, and the outer retinal layer thicknesses (correlation coefficients: 0.194, 0.154, and 0.364, respectively). However, the inner nuclear layer negatively correlated with visual acuity. Conclusions: Using retinal segmentation via SD-OCT for follow-ups can help estimate visual loss in patients with Behçet uveitis, which can cause significant changes in intraretinal layers in the macular region.

RESUMO Objetivo: Avaliar a espessura das camadas intraretinianas na região macular e sua relação com a duração da uveíte e acuidade visual em pacientes com uveíte de Behçet. Métodos: Este estudo transversal incluiu 93 olhos de 57 pacientes com uveíte de Behçet e 100 olhos de 50 indivíduos saudáveis que foram admitidos em um hospital terciário entre janeiro de 2017 e setembro de 2017. As medições maculares foram realizadas com tomografia de coerência óptica de domínio espectral (SD-OCT) em todos os pacientes. A retina foi dividida em camadas usando software de segmentação automatizado no dispositivo SD-OCT. As espessuras da camada foram comparadas entre os pacientes e os grupos controle. No grupo de pacientes, foi avaliada a correlação entre os parâmetros obtidos na OCT e a duração da uveíte e acuidade visual. Resultados: A média de idade foi de 37,9 ± 10,8 (18-64) no grupo de pacientes e 37,7 ± 12,2 (21-61) no grupo controle (p=0,821). A duração média da uveíte foi de 6,9 ± 4,7 (1-20) anos. A espessura total das camadas externas no grupo de pacientes foi reduzida (p<0,001). Uma diferença estatisticamente significativa não foi encontrada nas camadas internas da retina, exceto na camada nuclear interna. Uma correlação negativa foi detectada entre a duração da uveíte e a espessura da camada externa da retina (coeficiente de correlação = -0,250). Uma correlação positiva significativa foi detectada entre a acuidade visual e a espessura macular central bem como a espessura total das camadas internas e externas da retina (coeficientes de correlação 0,194; 0,154 e 0,364, respectivamente). A camada nuclear interna foi negativamente correlacionada com a acuidade visual. Conclusões: A uveíte de Behçet pode causar alterações significativas nas camadas intraretinianas na região macular. A segmentação da retina com SD-OCT pode ser útil para acompanhamentos e para estimar a perda visual em pacientes com uveíte de Behçet.

Cardiac Thrombosis in Behçet's Disease: A Diagnostic Challenge

Intracardiac masses have several etiologies: tumor, infectious, thrombotic. They constitute a diagnostic challenge for the clinician. Behçet's disease is a chronic multisystemic vasculitis evolving by relapses. Intracadiac thrombosis in this disease deserves special attention because of its life-threatening nature. They often appear in the early stages of the disease, and the most frequent location is the right heart chambers. We present the case of a 23-year-old patient with an isolated mass in the right ventricle revealing an initial manifestation of Behçet's disease. The presented clinical case highlights the importance of early recognition of Behçet's disease, as well as the awareness of including this disease in the differential diagnosis of intracardiac masses in young adults.

Clinical profile and management with immunosuppressants and biologics in Behcet’s uveitis: A cohort of 25 patients from a tertiary eye care center in South India

Purpose: To report the clinical profile of Behcet’s disease and its management with immunosuppressants and biologics in a cohort of 25 patients from a tertiary eye care center in South India. Methods: This was a retrospective, observational study. Records of 45 eyes of 25 patients between January 2016 and December 2021 were retrieved from the hospital database. Complete ophthalmic evaluation and systemic examination by the rheumatologist with appropriate investigations had been done. Results were analyzed using Statistical Package for the Social Sciences (SPSS) software. Results: Males (19, 76%) were found to be more affected than females (6, 24%). Mean age of presentation was 27.68 ± 11.08 years. Twenty patients had bilateral involvement (80%), and unilateral involvement was seen in five patients (20%). Seven eyes of four patients (16%) had isolated anterior uveitis, out of which one patient had unilateral and three patients had bilateral involvement. Twenty?six eyes of 16 patients (64%) had posterior uveitis, out of which six patients had unilateral and 10 had bilateral involvement. Twelve eyes of seven patients (28%) had panuveitis, out of which two patients had unilateral and five had bilateral involvement. Hypopyon was seen in five eyes (11.1%) and posterior synechiae in seven eyes (15.55%). Posterior segment findings included vitritis (24.44%), vasculitis (17.78%), retinitis (17.78%), disc hyperemia (11.11%), and disc pallor (8.89%). Steroids alone were given in five patients (20%) and intravenous methylprednisolone (IVMP) was given in four patients (16%). Immunosuppressive agents along with steroids were given in 20 patients (80%), of which azathioprine alone was given in seven patients (28%), cyclosporin alone was given in two patients (8%), mycophenolate mofetil alone was given in three patients (12%), combination of azathioprine and cyclosporin was given in six patients (24%), and combination of methotrexate and mycophenolate mofetil was given in one patient (4%). Biologics were given in 10 patients (40%) – adalimumab in seven patients (28%) and infliximab in three patients (12%). Conclusion: Behcet’s disease is an uncommon uveitis in India. Addition of immunosuppressants and biologics to conventional steroid therapy gives better visual outcomes.

Dilated Cardiomyopathy with Biventricular Thrombi: A Severe Manifestation of Behcet Disease

Behcet’s disease is a systemic vasculitis of the vessels for all calibers, touching arterial and venous territories. The causes of disease are unknow. BD reaches young age subjects from 10 to 45 years and affects both men and women. BD is ubiquitous but more frequent in patients from Mediterranean basin, the middle East and Asia. The diagnosis of BD is essentially clinical. The diagnostic criteria make it possible to carry the diagnosis with good sensitivity and specifity. BD evolves by recurrent inflammatory attack. BD can affect all of the organs; cardiacs manifestations are dominated by intracardiac thrombosis, the damage of three tunics, coronaryarteritis with or without myocardial infarction, coronaries aneurysms and endomyocardial fibrosis. The vascular manifestations are dominated by arterial or venous thrombosis. The presence of dilated cardiomyopathy with reduced left ventricular ejection fraction is rare. It can be explained by ischemic or inflammatory origin by cytokines. We report a case of young woman aged of 33 years to the history of 3 episodes of bipolar aphtae which presented dilated cardiomyopathy with reduced left ventricular function, biventricular thrombosis, bilateral distal pulmonary embolism with pulmonary infarction.

The roles of immune cells in Behçet's disease

Abstract Behçet's disease (BD) is a systemic vasculitis that can affect multiple systems, including the skin, mucous membranes, joints, eyes, gastrointestinal and nervous. However, the pathogenesis of BD remains unclear, and it is believed that immune-inflammatory reactions play a crucial role in its development. Immune cells are a critical component of this process and contribute to the onset and progression of BD. By regulating the function of these immune cells, effective control over the occurrence and development of BD can be achieved, particularly with regards to monocyte activation and aggregation, macrophage differentiation and polarization, as well as T cell subset differentiation. This review provides a brief overview of immune cells and their role in regulating BD progression, which may serve as a theoretical foundation for preventing and treating this disease.

The patient responded favorably in relation to the course of the infections, to the therapy with immune stimulants. Conclusions: Treatment must be individualized, taking into account the severity of the affected organ and the recurrence rate. An interdisciplinary group is required to achieve adequate control of the disease.

The clinical characteristics and surgical prognosis of Beh?et′s disease with heart valve involvement and literature review / 中华风湿病学杂志

Objective:To investigate the clinical characteristics and treatment of Beh?et′s disease complicated with cardiac valve involvement.Methods:We searched the wanfang medical database and Medline database to reviewed the domestic and foreign literature reports on cardiac Beh?et′s disease and analyzed their clinical features and therapeutic strategies. Chi-squared test was used for data analysis.Results:It was shown that Beh?et′s disease with cardiac valve involvement mainly affect men. The male to female ratio was 3.86∶1 in China and 2.50∶1 in foreign patients( χ2=1.32, P=0.251). The preoperative diagnosis rate was not high(60.3% in China, 57.1% abroad) ( χ2=0.13, P=0.716). Aortic valve and perivalvular lesions were the most common involved sites, of which aortic regurgitation was the most frequenty occurred, followed by mitral valve lesions. Glucocorticoids was still the main means treatment for medical(93/235 in China, 28/420 abroad), cyclophosphamide was more widely used in China(28/235), azathioprine was more widely used in foreign countries (12/42). Aortic replacement (AVR) was the mainly surgical approach, followed by artificial aortic valve replacement and left ventricular outflow tract plasty (Bentall).The incidence of postoperative perivalvular leakage or valve prolapse was higher with AVR than with Bentall(AVR 76.3%/Bentall 21.8% at home, χ2=32.60, P<0.001, AVR 71.4%/Bentall 0 abroad, χ2=13.84, P<0.001). Conclusions:Cardiac valve involvement is a severe complication of Beh?et′s disease. Heart involvement are more common, and the preoperative diagnosis rate is lower in China. The incidence of perivalve leakage (PVL) or valve prolapse (PD) after operation is higher with AVR than with Bentall surgery.The Bentall operation could improve prognosis and the postoperative complications abroad are lower than domestic.

Objective:To introduce the application of sleeve reconstruction with bovine pericardium in the reoperation of Behcet's disease with advanced aortic annulus invasion, and to report our experience and the early outcomes.Methods:From August 2012 to May 2022, 19 patients with Behcet's disease developed perivalvular leakage after previous surgery underwent aortic root replacement. They were analyzed retrospectively. Fifteen out of 19 cases underwent conventional aortic root replacement, 4 cases with advanced aortic annulus invasion underwent sleeve reconstruction with bovine pericardium. The medical records were reviewed. Demographic and perioperative data were collected, which included the aortic crossclamp time, intraoperative RBC consumption, length of ICU stay, and major postoperative complications.Postoperative follow-up was accomplished through telephone visit.Results:The median age was 39(36, 42) years old. Five were female. The median interval of diagnosis of perivalvular leak from index surgery was 5(3, 14)months. There was no perioperative death. Fifteen patients underwent conventional aortic root replacement. One patient had intraoperative ECMO impant due to low cardiac output as well as another one had IABP support. CABG was performed in 5 patients. One patient underwent permanent pacemaker implantation after surgery. The median follow-up time for the 15 patients was 55.00(29.25, 71.25)months. Two patients were lost during follow-up. One patient died of infection 3 years after surgery. One patient developed perivalvular leak. Two patient developed distal anastomotic pseudoaneurysm which need reintervention. The median follow-up time for the 4 patients with sleeve reconstruction was 5.5(5, 11.25)months. One patient underwent tracheotomy. Perivalvular leakage and pseudoaneurysm were not appreciated. Four patients were in NYHA class Ⅰ-Ⅱ.Conclusion:The sleeve reconstruction with bovine pericardium is safe and effective in reoperation treating patients with Behcet's disease and advanced aortic annulus invasion.

Intestinal Behcet’s : A Rare Presentation of Behcet’s Disease

We herein present a case of 48 years old female patient presented with fever, bloody diarrhea followed by palpable purpuric rash over the body along with recurrent oral and genital ulceration. These were associated with history of symmetric polyarthralgia. On examination moderate anemia, signs of anterior uveitis were found. In blood parameters thrombocytopenia along with elevated Erythrocyte Sedimentation Rate, C-Reactive Protein were noted. On further investigations the serological tests were found to be negative for Dengue, Chikungunya, HIV, HBV, HCV. Complement C3 found to be low. Colonoscopic biopsy is diagnostic of Indeterminate Crohn’s Disease with IgA, G, M, C3, Fibrinogen immunostaining in skin biopsy. ANA, P-ANCA, C-ANCA were found to be nonreactive for the patient. All of the above mentioned points were pointing towards Behcet’s disease. For confirmation, Anti Saccharomyces Cerevisae Antibody was found to be positive . Skin pathergy test was positive. So, we diagnosed this case as behcet’s disease.

Manifestaciones gastrointestinales de la nfermedad de Behçet / Gastrointestinal manifestations of Behçet´s disease

Resumen La Enfermedad de Behçet (EB), es una entidad poco común, idiopática, de naturaleza crónica y recurrente con afectación multisistémica. Entre ellos, el tracto gastrointestinal ha suscitado especial interés, al asociarse a mayor morbimortalidad y dado sus presentaciones heterogéneas puede simular otras enfermedades gastrointestinales y ser un gran reto diagnóstico para el gastroenterólogo. Por lo tanto, presentamos una revisión narrativa donde se pretenderá describir las manifestaciones gastrointestinales de la EB y sus diagnósticos diferenciales.

Abstract Behçet's Disease (BD) is a rare, idiopathic, chronic and relapsing entity; characterized by multisystem involvement. The gastrointestinal tract has aroused special interest, as it is associated with higher morbidity and mortality and given its heterogeneous presentations, being able to simulate other gastrointestinal pathologies, becoming a great diagnostic challenge for gastroenterologists. Therefore, we present a narrative review, where we intend to describe the possible gastrointestinal manifestations of BD and its differentials.

O intestino delgado é amplamente afetado na doença de Behçet: um acompanhamento de longo prazo dos sintomas gastrointestinais / Small bowel is largely affected in behçet's disease: a long-term follow-up of gastrointestinal symptoms

ABSTRACT Background Behçet's disease is a rare immune-mediated disorder that can affect the gastrointestinal tract. The prevalence and extension of small bowel involvement is largely unknown. Objective The aim of this study was to describe the small bowel lesions diagnosed by double-balloon enteroscopy (DBE) and to verify if these findings were associated to the presence of gastrointestinal symptoms and disease activity after long-term follow-up. Methods This study included 19 Behçet's disease patients who underwent DBE. After a mean follow-up of 15 years the endoscopic findings were associated to the presence of gastrointestinal symptoms, disease activity and current therapy through collection of electronic medical records. Results A total of 63.2% patients were female and the mean age was 37 years at the time of DBE. Mean disease duration at baseline was 24 years. 11 patients had no gastrointestinal symptoms and eight patients presented either abdominal pain, gastrointestinal bleeding or diarrhea. The average procedure time was 1 hour and 30 minutes and the ileum was achieved in all patients but one. Small bowel ulcers were diagnosed in 78.9%, with 63.1% of jejunal involvement. Two patients presented only small bowel edema and two were normal by DBE. Eight patients had concomitant gastric ulcers. Gastrointestinal symptoms prior to DBE were present in 36.8% of the patients and, after follow-up, all of them persisted with some of the symptoms. Bleeding was reported by three patients at baseline and persisted in only one patient. The frequency of treatment with steroids and immunomodulators was 31.6% and 57.9% at baseline, respectively, and 21% in both at the end of the follow-up. No patient was treated with biologics at the time of the DBE procedure and the current rate of biologic use is 21%. Conclusion Small bowel involvement in Behçet's disease was frequently demonstrated by DBE even in asymptomatic patients. Understanding clinical evolution of the disease over the years and the impact of such diagnosis still represents a challenge, possibly with the need for novel treatment.

RESUMO Contexto A doença de Behçet é uma doença imunomediada rara que pode afetar o trato gastrointestinal. A prevalência e extensão do envolvimento do intestino delgado é desconhecida. Objetivo O objetivo deste estudo foi descrever as lesões do intestino delgado diagnosticadas por enteroscopia de duplo balão (EDB) e verificar se esses achados estavam associados à presença de sintomas gastrointestinais e atividade da doença após seguimento de longo prazo. Métodos Este estudo incluiu 19 pacientes com doença de Behçet que foram submetidos a EDB. Após seguimento médio de 15 anos, os achados endoscópicos foram associados à presença de sintomas gastrointestinais, atividade da doença e terapia atual por meio de coleta de prontuário eletrônico. Resultados Um total de 63,2% dos pacientes eram do sexo feminino e a média de idade era de 37 anos no momento da EDB. A duração média da doença no início do estudo foi de 24 anos. 11 pacientes não apresentaram sintomas gastrointestinais e oito pacientes apresentaram dor abdominal, sangramento gastrointestinal ou diarréia. O tempo médio do procedimento foi de 1 hora e 30 minutos e o íleo foi atingido em todos os pacientes, exceto em um. Úlceras de intestino delgado foram diagnosticadas em 78,9%, sendo 63,1% de acometimento jejunal. Dois pacientes apresentaram apenas edema de intestino delgado e dois apresentaram EDB normais. Oito pacientes tinham úlceras gástricas concomitantes. Sintomas gastrointestinais prévios à EDB estavam presentes em 36,8% dos pacientes e, após o seguimento, todos persistiram com alguns dos sintomas. Sangramento foi relatado por três pacientes no início do estudo e persistiu em apenas um paciente. A frequência de tratamento com esteroides e imunomoduladores foi de 31,6% e 57,9% no início do estudo, respectivamente, e 21% em ambos ao final do seguimento. Nenhum paciente foi tratado com biológicos no momento da EDB e a taxa atual de uso de biológicos é de 21%. Conclusão O envolvimento do intestino delgado na doença de Behçet foi frequentemente demonstrado por EDB mesmo em pacientes assintomáticos. Compreender a evolução clínica da doença ao longo dos anos e o impacto de tal diagnóstico ainda representa um desafio, possivelmente com a necessidade de novos tratamentos.

Tratamento endovascular na doença de Behçet: uma revisão integrativa / Endovascular treatment in Behçet's disease: an integrative review

Resumo A doença de Behçet (DB) é caracterizada por ser uma doença rara, crônica, recidivante, inflamatória e multissistêmica. Quanto ao diagnóstico, não existe nenhum teste universalmente descrito; logo, ele é feito de maneira clínica, por meio da presença da sua tríade clássica de sinais: úlceras orais, úlceras genitais e uveíte (inflamação do trato uveal do olho). O objetivo deste estudo foi avaliar a importância do tratamento endovascular na doença de Behçet, sendo que a revisão de literatura para obter essa resposta foi realizada a partir de 30 artigos publicados entre 2002 e 2021. A DB acomete tanto o sistema venoso quanto o arterial. A ruptura de aneurismas é a principal causa de morte e necessita de tratamento, podendo ser clínico, cirúrgico aberto ou por via endovascular. A cirurgia endovascular vem ganhando espaço no tratamento cirúrgico nos casos de aneurismas arteriais, inclusive nos relacionados com DB, apesar de a terapia de escolha ainda ser controversa.

Abstract Behçet's Disease (BD) is a rare, chronic, relapsing, inflammatory, and multisystemic disease. There is no universally described test for confirming diagnosis, so it is made clinically, on the basis of its classic triad of signs: oral ulcers, genital ulcers, and uveitis (inflammation of the uveal tract of the eye). The aim of this study is to evaluate the importance of endovascular treatment in Behçet's disease. The literature review conducted to achieve this objective covered 30 articles published between 2002 and 2021. Behçet's Disease affects both the venous and arterial systems. Rupture of aneurysms is the main cause of death and thus requires treatment, which can be clinical, open surgical, or endovascular. Endovascular surgery has been gaining ground for surgical treatment of arterial aneurysms, including those related to BD, although the therapy of choice is still controversial.

The Relationship between Serum IL-17 and IL-23 Levels, and Other Disease Activity Parameters in Patients with Behçet's Disease

ABSTRACT Objective: To investigate the relationship between disease activity and the involvement of Behçet's disease (BD) and serum levels of interleukin (IL)-17 and IL-23. Methods: Sixty patients with BD and 20 healthy control group subjects were included in this study. The patients were divided into four groups according to clinical findings as follows: entero-Behçet, mucocutaneous-Behçet, neuro-Behçet and vascular-Behçet. The serum levels of the IL-17 and IL-23 levels were evaluated using enzyme-linked immunosorbent assay. Results: Of the BD patients, 15 (25%) had active disease and 45 (75%) had inactive disease. The serum levels of IL-23 and IL-17 were statistically significantly higher in the patients with BD than in the control groups (p < 0.05). A significant relationship was also observed between the disease activity, and both the erythrocyte sedimentation rate and the C-reactive protein levels (p < 0.05). The mean serum levels of IL-17 and IL-23 in patients with active disease were 0.07 ± 0.25 pg/ml and 36.0 ± 30.5 pg/ml, respectively. There was no statistically significant relationship between the disease activity and the serum levels of IL-17 and IL-23 (p > 0.05). There were also statistically significant relationships between the disease activity and uveitis, retinal vasculitis or superficial thrombophlebitis. Conclusion: No relationship was found between BD and serum levels of the IL-17 and the IL-23.

Chronic pain and vitamin B12 deficiency, a challenging and important differential diagnosis. Case report / Dor crônica e deficiência de vitamina B12, um diagnóstico diferencial desafiador e importante. Relato de caso

ABSTRACT BACKGROUND AND OBJECTIVES: The study's objective was to present a case of diffuse chronic pain with 36 months of development, associated with recurrent oral aphthous ulcers and glossitis, highlighting the importance of the wide differential diagnosis and the possibility of vitamin B12 deficiency as a cause. CASE REPORT: Male patient, 39 years-old, white, reported diffuse pain predominantly in the cervical, thoracic, abdominal, thighs and left knee regions, besides the presence of frequent oral aphtae, lasting more than 5 days, multiple and painful, predominantly on the tongue, for 6 months. The condition was attributed to Behçet's disease, but there was complete and permanent remission after treatment with vitamin B12. CONCLUSION: It's important to insert vitamin B12 deficiency for differential diagnosis in chronic pain scenarios.

RESUMO JUSTIFICATIVA E OBJETIVOS: O objetivo deste estudo foi apresentar um caso de dor crônica difusa com 36 meses de evolução, associada com aftas orais de repetição e glossite, destacando a importância do amplo diagnóstico diferencial e da possibilidade da deficiência de vitamina B12 como causa. RELATO DO CASO: Paciente do sexo masculino, 39 anos, branco, referindo dores difusas que predominavam em região cervical, torácica, abdominal, coxas e joelho esquerdo, além da presença de aftas orais frequentes, com duração superior a 5 dias, múltiplas e dolorosas, predominando na língua, há 6 meses. O quadro foi atribuído à doença de Behçet, mas houve remissão total e permanente após tratamento com vitamina B12. CONCLUSÃO: É importante inserir a deficiência de vitamina B12 para o diagnóstico diferencial em quadros de dor crônica.

Enfermedad de Behçet frente a la enfermedad inflamatoria intestinal. Diferencias en la presentación clínica / Behçet's disease compared with inflammatory bowel disease. Differences in their clinical presentation

Resumen La enfermedad de Behçet es una enfermedad poco frecuente con un compromiso sistémico cuyas principales manifestaciones abarcan el sistema gastrointestinal, neurológico, vascular y articular, además de la piel y los ojos. Por su compromiso multisistémico, es frecuente confundirlo con otras entidades como la enfermedad inflamatoria intestinal, con la cual comparte gran parte de su presentación clínica, por lo que se describe un caso clínico y se aborda una revision narrativa desde el punto de vista epidemiológico de las manifestaciones clínicas con el fin de tener un mayor conocimiento para identificarla a tiempo.

Abstract Behçet's disease is a rare disease with systemic involvement whose main manifestations include the gastrointestinal, neurological, vascular, and articular systems, as well as the skin and eyes. Due to its multisystemic nature, it is often mistaken for other entities such as inflammatory bowel disease since they share multiple characteristics in their clinical presentation. A clinical case is described, and an epidemiological review of clinical manifestations is discussed to have better knowledge that allow identifying it on time.

Vasculitis damage index in Behçet's disease

Abstract Background: Vasculitis damage index (VDI) is a validated damage index for systemic vasculitis, and as Behçet's disease is considered one of systemic vascular disease we aimed to study the relationship of the vasculitis damage index to clinical manifestations and comorbidity in patients with Behçet's disease (BD) to determine if VDI could be used to assess damage in patients with BD. Methods: A total of 109 patients with BD were recruited from the Rheumatology Department (outpatient and inpatient clinic), Cairo University Hospitals. All patients were subjected to full history taking, clinical examination, and routine laboratory investigations. Disease activity was assessed by the BD current activity form, and the VDI was calculated in all patients. The relationship of the VDI to the disease clinical manifestations was studied. Mann-Whitney and Kruskal Wallis tests were used to estimate differences in quantitative variables. Spearman correlation test was used to test for correlation between quantitative variables. Results: In the current study, the VDI ranged from 1 to 10, with a mean of 3.5 ± 1.8. It was significantly associated with total thrombosis (P = 0.022); total neurological manifestations (P = 0.000), especially stroke and cranial nerve affection; uveitis (P = 0.005); avascular necrosis (AVN) (P = 0.015); osteoporosis (P = 0.01); impaired vision (P < 0.0001); cataract (P < 0.0001); and diabetes (P = 0.012). Generally, immunosuppressive treatment was significantly associated with VDI (P = 0.039), especially cyclophosphamide (P < 0.0001), biological agent (P = 0.008), chlorambucil (P = 0.003), and anticoagulant (P = 0.02). VDI was also significantly correlated with age (P = 0.033), disease duration (P = 0.029), and duration of eye involvement (P = 0.003). Conclusion: VDI is significantly associated with most disease parameters of BD, except for parameters such as mucocutaneous manifestations and uncomplicated venous thrombosis; however, further studies may be needed to establish BD-specific damage index.

Objective:To investigate endoscopic and clinical characteristics of intestinal Behcet′s disease (BD) in children.Methods:General information, clinical manifestations, laboratory tests, imaging examinations and endoscopic characteristics of 14 children with intestinal BD treated in the Department of Gastroenterology, Beijing Children′s Hospital Affiliated to Capital Medical University from January 2016 to March 2020 were retrospectively analyzed.Results:Fourteen children with intestinal BD were recruited, involving 5 males and 9 females with the age of 1 month to 12 years and 11 months [(6.68±3.73) years old], and a median disease course of 6 months.All of them had gastrointestinal symptoms, including 11 cases with abdominal pain, 7 cases with diarrhea and 2 cases with vomiting.Complications of children with intestinal BD included gastrointestinal bleeding, intestinal perforation and stenosis.Extragastrointestinal symptoms included recurrent oral aphthosis in all the 14 cases, fever in 11 cases, skin lesions in 9 cases, vascular manifestations in 8 cases, positive pathergy test in 6 cases, joint manifestations in 5 cases, neurological manifestations in 1 case, and malnutrition in 6 cases.Observed by the endoscopy, lesions were mainly distributed in the distal ileum [61.5%(8/13 cases)]and ileocecal part[53.8%(7/13 cases)], with the main manifestation of ulcer.There were 3 cases with single ulcer and 10 cases with multiple ulcers, including 7 cases with deep and large ulcers.Pathological examinations of endoscopic lesions showed that the main features were mucosa chronic nonspecific inflammation, mucosa chronic active inflammation with ulcer and vasculitis.Conclusions:Clinical manifestations of intestinal BD vary a lot and are non-specific.Some children with intestinal BD may develop severe complications.Endoscopic lesions of intestinal BD have certain characteristics, which contribute to the diagnosis.Gastroenterologists need to be fully aware of intestinal BD.

Current treatment of vascular Behcet′s disease / 国际外科学杂志

Behcet′s disease is a chronic, multisystemic, inflammatory disease characterized by recurrent episodes of mucous membranes, eyes, musculoskeletal, blood vessels, central nervous system, and gastrointestinal tract.The treatment of Behcet′s disease varies according to the degree of organ involvement, gender and age of the patient, and there is no standard treatment. Behcet′s disease can be divided into vascular type, gastrointestinal type and neural type. Vascular type often leads to high mortality and disability rate.Glucocorticoids, azathioprine and cyclophosphamide are still recommended as first-line treatments for vascular Behcet′s disease.However, with the use of tumor necrosis factor inhibitors, they are an acceptable option for the treatment of refractory vascular Bezier′s disease.This article reviews the current treatment of vascular Behcet′s disease.
