Major vessel involvement in Behçet’s disease: an update. Curr Opin Rheumatol. 2011;23:24-31. [PMID: 21124084 DOI: 10.1097/bor.0b013e3283410088]

Clinical characteristics of coronary artery involvement in children with Behcet's syndrome

OBJECTIVES

To review the clinical features, treatment, and prognosis of coronary involvement in Behcet's syndrome in children.

METHODS

Retrospectively analyzed medical records of BS patients admitted to our institution from 2012 to 2024.

RESULTS

Six children with BS with coronary involvement were admitted, including 2 males and 4 females. The mean age was 5.7 years and the mean course was 17.2 months. All of them had coronary dilatation, including 1 case with aneurysmal dilatation, 2 cases with bilateral coronary dilatation, 4 cases with unilateral dilatation, and 4 cases with valvular disease. No symptom for coronary artery dilation and all of coronary dilatation were detected by echocardiography. Manifestations of extracardiac vascular involvement included arteriovenous wall thickness and thrombosis. Five cases had only arterial involvement and one case had both artery and vein involvement. Pulmonary artery was involved in 1 case. All of them were treated with glucocorticoid and immunosuppressant, 1 child was treated with TNF-α, and 1 received aortic valvuloplasty due to a large number of aortic regurgitations. The patient with coronary aneurysm died suddenly after giving up treatment, and the other 4 cases were all improved to varying degrees.

CONCLUSION

Vascular involvement is an important factor affecting the prognosis of Behcet's syndrome. Patients with coronary involvement are occultic and difficult to diagnose. Both arteries and veins can be involved, and some patients have severe symptoms. Clinicians should attach great importance to early vascular screening, especially coronary artery. Early combined medication may help improve the prognosis. Key Points • Vascular involvement is an important factor affecting the prognosis of Behcet's syndrome. • Coronary involvement in BS is rare in children, which is predominantly coronary dilatation. • The onset of BS with coronary involvement is insidious and easy to be missed, so early coronary artery screening in children with BS should be emphasized. • Early combined medication may help improve the prognosis of BS with coronary involvement.

Case Report: A Ticking Time Bomb: Femoral Artery Aneurysm as a Complication of Behcet's Disease in Adolescents

Behcet's disease is a rare, chronic inflammatory disorder that can affect various organs, with large vessel involvement being particularly uncommon. This case report discusses a 17-year-old male with Behcet's disease who presented with a rapidly enlarging, painful mass in the right groin region, later diagnosed as a femoral artery aneurysm. The patient underwent successful surgical intervention and was subsequently managed with immunosuppressive therapy to prevent relapse.

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.

A Challenging Diagnosis of Behçet's Disease Starting from Unexplained Fever Recurrence with Pulmonary Embolism: A Case Report

Purpose

Recurrent inflammatory fevers with multisystem involvement occur clinically and may indicate an autoimmune disease.

Case

We present a young male diagnosed with pulmonary embolism who experienced recurrent fever during hospitalization and was unresponsive to antibiotics and antipyretics. A follow-up history revealed chronic oral and genital ulcers, leading to a final diagnosis of Behçet's disease.

Conclusion

The patient's temperature normalized rapidly after corticosteroid therapy, and infection markers returned to normal. Complete remission was achieved with immunosuppression and glucocorticoid therapy. Reporting characteristics, treatment experience, and outcomes of such cases are essential to inform future diagnosis and management strategies.

Association of endomyocardial fibrosis and minor myocarditis sequelae with intracardiac thrombus and Ebstein like valvulopathy in a patient with Behçet disease: a case report

Background

Cardiac complications occur in 1-6% of cases of Behçet disease (BD) with intracardiac thrombus being the most frequent complication. Endomyocardial fibrosis, less common and occasionally associated with intracardiac thrombus, is reported in <20 case reports of BD, among which, three cases are described to mimic Ebstein disease based on echocardiography. We present the first case in the literature of a 34-year-old man with BD diagnosed with multiple cardiovascular complications, highlighting the challenging diagnosis and treatment of this pathology, especially regarding anticoagulation therapy.

Case summary

A 34-year-old man, diagnosed with BD, presented to the Emergency Room with haemoptysis. Computed tomography study of the thorax diagnosed pulmonary arterial aneurysm with multiple arterial thrombi, associated with multiple intracardiac thrombi in the right ventricle and atrium. The echocardiography confirmed the presence of voluminous thrombi in the right ventricle and atrium and showed hypertrabeculation of the right ventricle and a high insertion of the posterior leaflet of the tricuspid valve inducing a moderate tricuspid insufficiency compatible with an Ebstein disease. The cardiac MRI later revealed right ventricular fibrosis consistent with endomyocardial fibrosis and sequelae of myocarditis, also described as BD rare cardiac manifestations. The patient had a favourable outcome under anticoagulant treatment and immunosuppressive drugs.

Discussion

The association of multiple cardiovascular complications can occur in a single patient with BD. The endomyocardial fibrosis in the right heart chambers acting as a substrate for thrombus formation and subsequent pulmonary embolism; fibrosis extending to the tricuspid valve inducing an Ebstein-like morphology.

Gastrointestinal Behçet's disease: Manifestations, diagnosis, and management

Behçet's disease (BD) is a rare, inflammatory vascular disorder with recurrent oral and genital aphthous ulcers, along with ocular and cutaneous manifestations. Gastrointestinal (GI) BD may involve any portion of the GI tract. However, it is commonly described in the terminal ileum, followed by the ileocecal region. Diagnosis is challenging given lack of pathognomonic tests; therefore, it is based on clinical criteria. Management of intestinal BD includes different classes of medications including corticosteroids, 5-aminosalicylic acid, immunomodulators, and anti-tumor necrosis factor alpha monoclonal antibody agents. In this review, we aim to focus on intestinal BD and provide details of clinical manifestations, diagnosis and therapeutic options of intestinal BD from gastroenterology viewpoint.

Long-Term Outcome and Prognosis of Noninfectious Thoracic Aortitis

BACKGROUND

Aortitis is a group of disorders characterized by the inflammation of the aorta. The large-vessel vasculitides are the most common causes of aortitis. Aortitis long-term outcomes are not well known.

OBJECTIVES

The purpose of this study was to assess the long-term outcome and prognosis of noninfectious surgical thoracic aortitis.

METHODS

This was a retrospective multicenter study of 5,666 patients with thoracic aorta surgery including 217 (3.8%) with noninfectious thoracic aortitis (118 clinically isolated aortitis, 57 giant cells arteritis, 21 Takayasu arteritis, and 21 with various systemic autoimmune disorders). Factors associated with vascular complications and a second vascular procedure were assessed by multivariable analysis.

RESULTS

Indications for aortic surgery were asymptomatic aneurysm with a critical size (n = 152 [70%]), aortic dissection (n = 28 [13%]), and symptomatic aortic aneurysm (n = 30 [14%]). The 10-year cumulative incidence of vascular complication and second vascular procedure was 82.1% (95% CI: 67.6%-90.6%), and 42.6% (95% CI: 28.4%-56.1%), respectively. Aortic arch aortitis (HR: 2.08; 95% CI: 1.26-3.44; P = 0.005) was independently associated with vascular complications. Descending thoracic aortitis (HR: 2.35; 95% CI: 1.11-4.96; P = 0.031) and aortic dissection (HR: 3.08; 95% CI: 1.61-5.90; P = 0.002) were independently associated with a second vascular procedure, while treatment with statins after aortitis diagnosis (HR: 0.47; 95% CI: 0.24-0.90; P = 0.028) decreased it. After a median follow-up of 3.9 years, 19 (16.1%) clinically isolated aortitis patients developed features of a systemic inflammatory disease and 35 (16%) patients had died.

CONCLUSIONS

This multicenter study shows that 82% of noninfectious surgical thoracic aortitis patients will experience a vascular complication within 10 years. We pointed out specific characteristics that identified those at highest risk for subsequent vascular complications and second vascular procedures.

Long Term Outcomes and Potential Risk Factors for Endovascular Repair of Aortic Pseudoaneurysms in Vascular Behçet's Disease

OBJECTIVE

This study aimed to analyse long term outcomes and risk factors for endovascular repair of aortic pseudoaneurysms in patients with vascular Behçet's disease (BD).

METHODS

Medical records of 26 aortic vascular BD patients who underwent endovascular treatment at the vascular department of Peking Union Medical College Hospital between January 2002 and December 2021 were reviewed retrospectively. Erythrocyte sedimentation rate (ESR) and C reactive protein were used to assess BD activity. Computed tomography angiography (CTA) was obtained pre- and post-operatively for almost all patients. Univariable logistic regression analysis was used to analyse risk factors for endovascular repair, such as inflammatory indicators, drug usage, and stent graft parameters.

RESULTS

The abdominal aorta (n = 17) was the most common site of 27 vascular BD pseudoaneurysms in this study. CTA also revealed one aortic arch pseudoaneurysm, seven descending thoracic aortic pseudoaneurysms, one thoraco-abdominal aortic pseudoaneurysm, and one pseudoaneurysm at the aortic bifurcation. Most of the pseudoaneurysms were treated with covered stent grafts. The technical success rate was 96% and no deaths occurred during hospital stay. The mean follow up was 5.8 ± 5.5 years and 31% (8/26) experienced post-operative complications. Overall one, three, and five year event free survival rates were 87%, 78%, and 74%, respectively. Univariable logistic regression analysis revealed that pre-operative ESR ≥ 16.0 mm/h (p = .040), pre-operative glucocorticoid (GC) use ≤ 11.5 days (p = .024), pre-operative immunosuppressant use ≤ 15.5 days (p = .028), and length of proximal landing zone ≤ 1.95 cm (p = .034) were associated with a worse prognoses following endovascular treatment. Proximal oversize ≥ 9.5% (p = .074) was also regarded as a risk factor, although not statistically significant.

CONCLUSION

This study further confirmed the feasibility of endovascular repair for aortic vascular BD patients. Risk factors predicting poor prognoses included elevated pre-operative ESR, insufficient pre-operative GC use or immunosuppressant use, inadequate proximal landing zone, and larger proximal oversize percentage.

Treatment Options in Pediatric Behçet's Disease

Behçet's disease is a rare and poorly understood vasculitis affecting blood vessels of all types and sizes. Uveitis and oral and genital ulcers represent the typical clinical triad. Populations along the ancient trading route connecting the Mediterranean basin with the Middle and Far East are most affected. Up to a quarter of the cases has a pediatric onset, typically around puberty. The aim of the treatment is early intervention to control inflammation, with symptom relief and prevention of relapses, damage, and complications. The heterogeneous clinical presentation often requires a multidisciplinary and tailored approach. Ocular, neurological, gastrointestinal, and vascular involvement is associated with a worse prognosis and needs more aggressive treatments. In young patients with expected prolonged disease, treatment should also focus on preventive measures and lifestyle advice. In recent years, the pharmacological armamentarium has grown progressively, although only a limited number of drugs are currently authorized for pediatric use. Most evidence for these drugs still derives from adult studies and experience; these are prescribed as off-label medications and are only available as adult formulations. Corticosteroids frequently represent the mainstay for the management of the initial acute phases, but their potential serious adverse effects limit their use to short periods. Different conventional disease-modifying anti-rheumatic drugs have long been used. Many other biologic drugs targeting different cytokines such as interleukin-1, interleukin-6, and interleukin-17 and treatments with small molecules including the phosphodiesterase 4 and Janus kinase inhibitors are emerging as novel promising therapeutic agents. In recent years, a growing interest has developed around anti-tumor necrosis factor agents that have often proven to be effective in severe cases, especially in those with a gastrointestinal and ocular involvement.

[Vascular manifestations of Behcet's disease]

Behçet disease is a multi-systemic complex vasculitis with unknown etiology characterized by different clinical involvements, including mucocutaneous, ocular, vascular, articular, neurological and gastrointestinal manifestations. Growing evidence supports that different phenotypes, characterized by clusters of co-existing involvements, can be distinguished. Namely, the vascular phenotype identifies a specific group of patients who suffer from recurrent inflammatory thrombosis and arterial involvement. Vascular disease develops in up to 40% with a definite male preponderance and is usually an early manifestation. It is one of the main causes of death in Behçet's disease. Venous involvement is significantly more common than arterial disease and lower extremity deep vein thrombosis is its most frequent manifestation. Arterial disease involves mostly pulmonary arteries and aorta and manifests mainly in the form of aneurysms. Glucocorticoids and immunosuppressant's are the recommended first-line treatments in vasculo-Behçet. Furthermore, randomized controlled trials are still needed to assess the role of adding anticoagulation to current standard therapy in venous thrombosis in Behçet's disease and to assess the role of anti-TNF alpha therapy in vasculo-Behçet.

Surgical treatment for Behcet's disease with acute superior vena cava syndrome

BACKGROUND AND AIM OF THE STUDY

Behcet's disease (BD) is a multisystem vasculitis with unknown etiology. The involvement of superior vena cava (SVC) is reported in less than 2% of patients with BD.

METHODS

We report a patient with acute edema of neck and face associated with dyspnea as the primary manifestation. So a diagnosis of superior Vena Cava syndrome (SVCS) was made and the thickening wall of SVC was resected. An Operation was performed under cardiopulmonary bypass to remove the mass and thrombus for avoiding for pulmonary embolism.

RESULTS

The diagnosis of Behcet's disease (BD) didn't not be made until the recurrent oral and genital ulceration occurred 2 weeks later. The patient taked aspirin and prednisolone orally as prescribed and no recurrence were observed during the 30 months follow-up.

CONCLUSIONS

BD should be suspected in patients presenting with SVCS, when there is thickening of SVC, whether thrombosis or not. Early diagnosis and treatment are essential for management of BD.

Case report and analysis: Behçet’s disease with lower extremity vein thrombosis and pseudoaneurysm

Background

Behçet’s disease (BD) is a unique autoimmune chronic systemic vasculitis that affects veins and arteries of all sizes. BD can lead to recurrent vascular events, especially venous thrombosis, with an incidence rate of 40%, or pseudoaneurysms formed under long-term inflammatory reaction or iatrogenic stimulation. BD-related risk factors promote endothelial dysfunction, platelet activation and overactivation of tissue factors leading to mural inflammatory thrombi. Thrombosis may be the first clinical manifestation of BD.

Case presentation

A 32-year-old man complaining of progressive swelling and pain in the right lower extremity for 30 days was initially diagnosed with “venous thrombosis of the right lower extremity,” using color Doppler ultrasonography. Patient underwent inferior vena cava filter placement combined with deep vein angioplasty of the right lower extremity and catheter-directed urokinase thrombolysis. Postoperative oral anticoagulant therapy was administered. However, the patient was readmitted 20 days later for pulsatile pain in the right groin. Prior medical history included 4 years of repeated oral and perineal ulcers, and 2 months of blurred vision. Abdominal computed tomography angiography (CTA) revealed rupture of the right common iliac artery (CIA) and left internal iliac artery (IIA), complicated by a pseudoaneurysm. Based on the clinical manifestations and other auxiliary examination results, the patient was re-diagnosed with “BD combined with deep venous thrombosis of the right lower extremity and an iliac artery pseudoaneurysm.” Stent implantation was performed for iliac artery pseudoaneurysm after symptoms were controlled with timely immunosuppressive therapy. After endovascular treatment, the patient underwent continued immunosuppressive therapy and dynamic reexaminations of abdominal CTA, which revealed that a small amount of contrast agent at the stent in the right CIA continued to flow into the cavity of the pseudoaneurysm; in addition, the size of the pseudoaneurysm was gradually increasing. Therefore, the patient underwent a second stent implantation for iliac artery pseudoaneurysm, and the condition improved further.

Conclusion

The importance of early diagnosis of BD should be recognized, and the choice of interventional and surgical procedures should be carefully evaluated, as this may trigger further damage to vascular access in BD patients with aneurysm.

[Thoracic manifestations of Behcet's disease]

Behcet's disease (BD) is a multisystemic vasculitis involving arteries and veins of all sizes. While joint and dermatological manifestations are the most common features of BD and are associated with a good prognosis; vascular involvement, remains the principal cause of death. Arterial manifestations occur in 5-10% of cases and manifest as occlusion/thrombosis or aneurysms. Arterial aneurysms are likely multiple and the most common sites are pulmonary arteries, aorta and arteries of lower limbs. Parenchymal involvement is less frequent and may manifest as consolidation or nodules, which may evolve to excavation. Aneurysms may occur at the sites of arterial puncture; then, non-traumatic techniques are favored. Patients with arterial manifestations may present with fever and increased inflammatory markers. Artery damage is rare, serious, and may result in massive hemoptysis. The prognosis of pulmonary artery aneurysms is severe (mortality estimated up to 26%) but has been improved by earlier diagnosis and the introduction of immunosuppressants. Treatment of severe arterial manifestations is based on high-dose corticosteroids along with cyclophosphamide or anti-TNF antagonists. Anticoagulation could be added to immunosuppressants in case of venous thrombosis if a coexisting pulmonary aneurysm is ruled out. Endovascular treatment should be performed in case of severe symptomatic pulmonary aneurysms, along with an adequate medical management. Long-term maintenance therapy of these severe forms is of paramount importance because of relapse risk (40% at five years).

The role of cardiovascular magnetic resonance in the evaluation of acute myocarditis and inflammatory cardiomyopathies in clinical practice - a comprehensive review

Inflammatory cardiomyopathy (I-CMP) is defined as myocarditis in association with cardiac dysfunction and/or ventricular remodelling. It is characterized by inflammatory cell infiltration into the myocardium and has heterogeneous infectious and non-infectious aetiologies. A complex interplay of genetic, autoimmune, and environmental factors contributes to the substantial risk of deteriorating cardiac function, acute heart failure, and arrhythmia as well as chronic dilated cardiomyopathy and its sequelae. Multi-parametric cardiovascular magnetic resonance (CMR) imaging is sensitive to many tissue changes that occur during myocardial inflammation, regardless of its aetiology. In this review, we summarize the various aetiologies of I-CMP and illustrate how CMR contributes to non-invasive diagnosis.

Adamantiades-Behçet disease: from clinical heterogeneity to diagnosis during the COVID-19 pandemic

Adamantiades-Behçet Disease (ABD) is a systemic disease with vasculitis, characterised by recurrent oral aphthosis and ocular, cutaneous, articular, vascular, cardiopulmonary manifestations and it is mainly found in the territories of the antique "silk road. ABD pathogenesis remains unknown although genetic, infectious and environmental factors seem to be implicated in the development of the disease, which is considered an auto-inflammatory condition. COVID-19 infection can present some symptoms, in particular at the level of oral and pulmonary mucosa, which require a differential diagnosis with ABD. Furthermore, the immunological alterations of this disease, and the drugs used for its treatment could influence the infection by COVID-19, and its clinical evolution. Nevertheless, vaccination anti-COVID-19 is recommended in ABD patients. The most commonly used diagnostic criteria for ABD are those established in 2014 by the International Team for the Revision of the International Criteria for BD (ITR-ICBD). Furthermore, criteria for disease severity according to the Overall Damage Index of Behçet's syndrome (BODI) have recently been proposed in order to quantify the severity of the disease as well as the evolution during follow-up. In ABD patients it is mandatory to investigate on the presence of active/latent tuberculosis, because of the common organ involvement, such as eyes and bowel. ABD has a high morbidity and low mortality, sometimes linked to the rupture of an arterial aneurysm and/or neurological complications. This article is based on a general review on ABD ranging from the history of ABD to possible causes and clinical manifestations. A specific section has been dedicated to the COVID-19 pandemic.

Vascular complications of Behçet disease

Behçet disease is a multi-systemic complex vasculitis with unknown etiology characterized by different clinical involvements, including mucocutaneous, ocular, vascular, articular, neurological, and gastrointestinal manifestations. Growing evidence supports that different phenotypes, characterized by clusters of co-existing involvements, can be distinguished. Namely, the vascular phenotype identifies a specific group of patients who suffer from recurrent inflammatory thrombosis and arterial involvement. Vascular disease develops in up to 40% with a definite male preponderance and is usually an early manifestation. Venous involvement is significantly more common than arterial disease, and lower extremity deep vein thrombosis is its most frequent manifestation. Arterial disease involves mostly pulmonary arteries and aorta and manifests mainly in the form of aneurysms. Glucocorticoids and immunosuppressants are the recommended first-line treatments in vasculo-Behçet. Furthermore, controlled trials are still needed to assess the role of adding anticoagulation to the treatment regimen, with an accent on new oral anticoagulants. Treatment with anti-TNF alpha agents seems promising, but the management strategies are not clear yet.

Ultrasonographic measurement of the vascular wall thickness and intima-media thickness in patients with Behçet's disease with symptoms or signs of vascular involvement: A cross-sectional study

Objectives

This study aims to measure and compare bilateral carotid intima-media thickness (CIMT), bilateral jugular, common femoral, and main portal vein wall thicknesses (VWTs) in Behçet’s disease (BD) patients with and without vascular involvement to obtain a cut-off value for vascular complications and determine their relationship with disease activity.

Patients and methods

Sixty-three BD patients (41 males, 22 females; median age: 38.0 years; min 20 - max 71 years) and 30 healthy control subjects (14 males, 16 females; median age: 40.3 years; min 21 - max 60 years) were included in this cross-sectional study between February and March 2020. According to imaging findings, BD patients were divided into two groups as those with and without vascular complications. Disease duration, medical treatment and BD manifestations of patients were questioned. Disease activity was evaluated using the Behçet's Disease Current Activity Form (BDCAF) and the Behçet's Syndrome Activity Scale (BSAS). Two radiologists blinded to the diagnosis of BD used ultrasound to measure VWT and CIMT. Receiver operating characteristics were assessed to obtain sensitivity and specificity values for each VWT and CIMT.

Results

The groups were similar in terms of age, sex, and body mass index (p>0.05). There was a significant difference between the BD groups when the BDCAF and BSAS scores were compared, while there was no difference between them in terms of disease duration and medical treatment (p>0.05). All VWTs and CIMTs were significantly higher in patients with BD compared to healthy controls (p<0.05). There was no significant difference between the BD groups in terms of CIMT, jugular and common femoral VWTs (p>0.05). But portal VWT was significantly higher in patients with vascular involvement (p<0.05). A cut-off value of ≥1.35 mm yielded a sensitivity of 79.2% and a specificity of 82.4% for the diagnosis of vascular involvement with the highest Youden's index (area under the curve, 0.869; 95% confidence interval, 0.783 to 0.956).

Conclusion

Portal VWT has high sensitivity and specificity for the screening of vascular involvement in patients with BD.

Femoral vein wall thickness measurement: A new diagnostic tool for Behçet's disease

OBJECTIVES

Diagnosing Behçet's disease (BD) is a challenge, especially in countries with a low prevalence. Recently, venous wall thickness (VWT) in lower extremities has been shown to be increased in BD patients. In this study, we aimed to investigate the diagnostic performance of common femoral vein (CFV) thickness measurement in BD and whether it can be used as a diagnostic tool.

METHODS

. Patients with BD (n = 152), ankylosing spondylitis (n = 27), systemic vasculitides (n = 23), venous insufficiency (n = 29), antiphospholipid syndrome (APS; n = 43), deep vein thrombosis due to non-inflammatory causes (n = 25) and healthy controls (n = 51) were included in the study. Bilateral CFV thickness was measured with ultrasonography by a radiologist blinded to cases.

RESULTS

Bilateral CFV thickness was significantly increased in BD compared with all control groups (P < 0.001 for all). The area under the receiver operating characteristic curve for bilateral CFV thicknesses in all comparator groups was >0.95 for the cut-off value (0.5 mm). This cut-off value also performed well against all control groups with sensitivity rates >90%. The specificity rate was also >80% in all comparator groups except APS (positive predictive value: 79.2-76.5%, negative predictive value: 92-91.8% for right and left CFV, respectively).

CONCLUSION

Increased CFV thickness is a distinctive feature of BD and is rarely present in healthy and diseased controls, except APS. Our results suggest that CFV thickness measurement with ultrasonography, a non-invasive radiological modality, can be a diagnostic tool for BD with sensitivity and the specificity rates higher than 80% for the cut-off value ≥0.5 mm.

In-stent repeated thrombosis secondary to coronary artery aneurysms percutaneous coronary intervention in Behchet's Disease: A Case report

Coronary artery aneurysm (CAA) is a rare and poor prognostic manifestation of Behcet's disease （BD）. Percutaneous treatment approaches frequently failed to ameliorate acute coronary system (ACS). Long-term follow-up is recommended as the prognosis of coronary involvement and the risk of further disease progression with percutaneous intervention in BD are unknown. long-term anticoagulant and antiaggregant therapies should be considered to prevent further thrombosis and/or embolism.

Systemic vasculitides and the role of multitechnique imaging in the diagnosis

Vasculitis, a systemic disease characterised by inflammation of the blood vessels, remains challenging to diagnose and manage. Vessel size has been the basis for classifying systemic vasculitides. Imaging plays a vital role in diagnosing this challenging disease. This review article aims (a) to summarise up-to-date literature in this field, as well as include classification updates and (b) to review available imaging techniques, recent advances, and emphasis on imaging findings to diagnose large vessel vasculitides.

Pediatric Behçet's Disease

Behçet's Disease (BD) is a systemic vasculitis firstly described as a disorder causing aphthous lesion in oral and genital mucosae and uveitis. The disease has an extremely unique distribution characterized by the highest incidence in communities living along the historical Silk road. Although our understanding of the etiopathogenesis of BD has expanded over time, there are still lots of unidentified points in the underlying mechanisms of the disease. The accepted opinion in the light of the current knowledge is that various identified and/or unidentified infectious and/or environmental triggers can take a role as a trigger in individuals with genetic susceptibility. Although the disease usually develops in young adulthood, it is reported that about 15-20% of all Behçet's patients develop in childhood. Pediatric BD differs from adult BD not only with the age of onset but also in the frequency and distribution of clinical findings, disease severity and outcome. While gastrointestinal system involvement, neurological findings, arthralgia and positive family history are more common in children, genital lesions and vascular lesions are more common in adult patients. In addition, a better disease outcome with lower severity score and activity index has been reported in children. The diagnosis of the disease is made according to clinical findings. It can be challenging to diagnose the disease due to the absence of a specific diagnostic test, and the long time interval from the first finding of the disease to the full-blown disease phenotype in pediatric cases. Therefore, many classification criteria have been proposed so far. The widely accepted ones are proposed by the International Study Group. The new sets of classification criteria which is the only one for pediatric BD were also developed for pediatric cases by the PEDBD group. The primary goal for the treatment is preventing the organ damages by suppressing the ongoing inflammation and forestalling the disease flares. The treatment of the BD can be onerous due to its multisystemic nature and a multidisciplinary approach is essential for the management of the patients. In this review article, the definition, clinical findings, epidemiology, etiopathogenesis, and treatment will be discussed.

Acute coronary syndrome in Behcet's syndrome: A systematic review

Behcet syndrome is a rare vasculitis that affects both arteries and veins. Vasculo-Bechet Syndrome (VBS) is seen predominantly in men. Genetic predisposition and immune dysregulation leading to inflammation, endothelial damage, and impaired fibrinolysis contribute to its pathogenesis. Isolated case reports of Behcet syndrome (BS) with associated acute coronary syndrome (ACS) have been reported in the past. In this study, we present the first systematic review of such cases. A systematic search was conducted using Pubmed, Google Scholar, CINAHL, Cochrane CENTRAL, and Web of Science databases from 1980-2018 to identify case reports of myocardial infarction associated with BS. Cases that fulfilled the criteria for BS were selected for analysis. Demographic data, electrocardiography, echocardiography, angiography findings, and management were analyzed when available. We identified 62 case reports. Most subjects were men with a mean age of 37 years. Twenty-one percent were smokers, but other traditional cardiovascular risk factors were less common. Myocardial infarction was confirmed in half of the cases with findings on electrocardiogram (ECG). Echocardiogram revealed wall motion abnormality in 76% of patients, and angiography showed double-vessel disease in more than half of the cases. Mortality was reported in 1.6% of the cases. This systematic review shows that ACS in BS affects young males with low prevalence of coronary artery disease risk factors. Chest pain is the most common presenting feature and ST-segment elevation myocardial infarction (STEMI) was the most common ECG finding. Immunotherapy may be helpful to prevent future ACS in these patients.

Vessel wall MR imaging for the detection of intracranial inflammatory vasculopathies

Intracranial vasculopathies are routinely investigated by lumen-based modalities such as magnetic resonance angiography (MRA), computed tomography angiography (CTA), and digital subtraction angiography (DSA). These techniques are useful to analyze the vessel lumen, allowing to detect vessel stenosis or occlusion. However, the primum movins of the disease, i.e., an abnormal thickening of the vessel wall, remains within the arterial wall. The vasculopathy can moreover be present without always narrowing the lumen or modifying its regularity. Hence, there is a need to detect directly and analyze vessel wall abnormalities. Development of 3D high-resolution black blood sequences for intracranial vessel wall MR imaging (VW-MRI) enabled routine clinical applications not only vasculitis, but also of intracranial atherosclerotic disease (ICAD), intracranial dissections, reversible intracranial dissections, reversible cerebral vasoconstriction syndrome (RCVS), Moyamoya disease, and intracranial aneurysms. This high-resolution intracranial VW- MRI approach is increasingly used on a clinical basis at many centers to solve diagnostic problems, especially in patients with ischemic stroke or intracranial hemorrhage. An expert consensus Guideline from the American Society of Neuroradiology provides recommendations for clinical implementation of intracranial vessel wall MRI. There are several technical aspects needed to be considered when implementing VW-MRI in intracranial vessels, including flow suppression, both in blood and cerebrospinal fluid (CSF), spatial resolution and signal-to-noise ratio (SNR). In this article, we review the technical aspects of VW-MRI, and recommend applications for vascular diseases including non-occlusive intracranial vasculopathies, Moyamoya disease, and identifying culprit plaques. We also give a focus on the utility of VW-MRI for determining stroke etiology in adults and in children and young adults.

Serious Complication of Anticoagulation in Vessel Thrombosis-associated Behçet Disease

Anticoagulation in venous thrombosis associated with Behçet disease (BD) is controversial. We herein report a 47-year-old woman with vessel thrombosis and pulmonary artery aneurysm (PAA) associated with BD who died of massive hemoptysis under oral anticoagulant. Although she was initially diagnosed with oral contraceptive-induced venous thromboembolism, a subsequent investigation led to a diagnosis of BD. Follow-up computed tomography (CT) showed persistent thrombus, so anticoagulant was continued for persistent thrombus. She died of massive hemoptysis after the development of PAA was identified on follow-up CT during the period of anticoagulation. Great care to prevent bleeding events is required when administering anticoagulants for BD with vessel thrombosis.

An Adolescent Presented With Hemoptysis: Pulmonary Artery Aneurysm in Pediatric Behçet's Disease

Behçet's disease (BD) is a rare autoimmune and chronic inflammatory vasculitis, characterized by relapsing episodes of oral aphthous and genital ulcers, skin lesions, ocular lesions and vascular involvement. Pulmonary artery involvement is rare in BD but it carries a high mortality risk. In this article, we report a 15-year-old male patient presented with a two-month history of hemoptysis, cough, fewer and weight loss. On physical examination, auscultation revealed decreased breath sounds at left lung base. Bronchoscopy showed narrowed left lower lobe bronchus due to the external compression. Computed tomography angiography revealed multiple bilateral pulmonary artery aneurysms. Pathergy test was positive and he was diagnosed with BD. BD should be considered in the differential diagnosis of childhood hemoptysis.

Clinical characteristics and factors influencing the prognosis of Behçet’s disease complicated with vascular involvement

Summary: Background: Vascular Behçet's disease (VBD) might involve all sizes of arterial and venous vessels. Major vascular involvement caused the primary death in Behçet's syndrome (BS). We aimed to investigate the clinical characteristics and factors influencing the prognosis of VBD. Patients and methods: A retrospective analysis of the prospectively collected data of the Shanghai BS database from October 2012 to October 2018 was conducted. Patients who were diagnosed with BS and merged with venous thrombosis, arterial aneurysms, and arterial stenosis/occlusions were enrolled. Results: There were 47 patients with vascular involvement among 836 BS patients, 38 males and 9 females. The numbers of patients with venous thrombosis, arterial aneurysm, and arterial stenosis/occlusion were 25 (53.2 %), 21 (44.7 %), and 12 (25.5 %), respectively. Nearly half of the venous thromboses were located in limbs (n = 22, 46.8 %). Arterial aneurysm was the main form of arterial lesion. Most of the patients (93.6 %) were treated with corticosteroids and immunosuppressants. Late onset of BS or with arterial involvement had lower treatment response. Therapy with biological agents had significantly better results than that in the group without biological treatment (94.1 % vs. 80 %, P = 0.005). Conclusions: VBD showed a male preponderance and more than half of the patients presented with venous thrombosis. Late onset and arterial involvement were associated with poor prognosis. Therapy with biological agents is a viable alternative treatment to improve the prognosis.

Thoracic Complications in Behçet's Disease: Imaging Findings

Behçet's disease (BD) causes vascular inflammation and necrosis in a wide range of organs and tissues. In the thorax, it may cause vascular complications, affecting the aorta, brachiocephalic arteries, bronchial arteries, pulmonary arteries, pulmonary veins, capillaries, and mediastinal and thoracic inlet veins. In BD, chest radiograph is commonly used for the initial assessment of pulmonary symptoms and complications and for follow-up and establishment of the response to treatment. With the advancement of helical or multislice computed tomography (CT) technologies, such noninvasive imaging techniques have been employed for the diagnosis of vascular lesions, vascular complications, and pulmonary parenchymal manifestations of BD. CT scan (especially, CT angiography) has been used to determine the presence and severity of pulmonary complications without resorting to more invasive procedures, in conjunction with gadolinium-enhanced three-dimensional (3D) gradient-echo magnetic resonance (MR) imaging with the subtraction of arterial phase images. These radiologic methods have characteristics that are complementary to each other in diagnosis of the thoracic complications in BD. 3D ultrashort echo time (UTE) MR imaging (MRI) could potentially yield superior image quality for pulmonary vessels and lung parenchyma when compared with breath-hold 3D MR angiography.

Pediatric Behçet's disease - clinical aspects and current concepts

Behçet's Disease was first described by a Turkish dermatologist, Hulusi Behçet, in 1937 as a triple symptom complex; aphthous stomatitis, genital ulcers, and uveitis. Today, in light of current trials and experiments, we know that the disease may have a wider involvement with a multisystemic recurrent course, causing significant morbidity and mortality. However, there are still unanswered questions, particularly about Pediatric Behçet's Disease. Although several immunological and genetic associations have been demonstrated, the real etiologic mechanism of the disease is unclear. The diagnosis is difficult due to its rarity in childhood, the lack of validation of the diagnostic criteria obtained from adult studies, and the inadequacy of large case-controlled studies. Also, the management is challenging and controversial due to the various geographic distribution of clinical spectrum. New therapeutic options under development in light of pathogenetic hypothesis seem to be promising.

Prevalence of antiphospholipid antibodies in Behçet's disease: A systematic review and meta-analysis

Behçet's disease (BD) is a multifactorial systemic inflammatory disease of unknown aetiology characterised by several clinical manifestations including vascular involvements (i.e., both arterial and venous thrombosis). Antiphospholipid antibodies (aPLs)-including anticardiolipin (aCL), anti-β2-glycoprotein I (β2-GPI) antibodies and lupus anticoagulant (LA) are detected in systemic autoimmune diseases which contribute to thrombosis. The aim of this systematic review and meta-analysis was to evaluate the prevalence of aPLs in patients with BD as compared to controls. A protocol was registered in PROSPERO (Registration No. CRD42018088125) and a systematic literature search was conducted through PubMed, Web of Science, Embase, Scopus and ScienceDirect databases. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using random-effects model. Quality assessment was carried out by using the modified 9-star Newcastle-Ottawa Scale (NOS). Publication bias was evaluated via visualisation of contour- enhanced and trim and fill funnel plots along with Begg's and Egger's tests. We included ten case-control studies (a total of 999 participants from 380 BD patients and 619 controls) based on the inclusion criteria. The prevalence of aCL (OR: 12.10, 95% CI: 5.15-28.41, p<0.00001) and anti-β2-GPI antibodies (OR: 23.57, 95% CI: 1.31-423.63, p = 0.03) were statistically significant, however, the prevalence of LA was not significant (OR: 13.77, 95% CI: 0.65-293.59, p = 0.09). The results remained statistically significant from different sensitivity analyses which represented the robustness of this meta-analysis. According to the NOS, 50.0% of the studies were considered as of high methodological quality (low risk of bias). No significant publication bias was detected from contour-enhanced and trim and fill funnel plots or Begg's and Egger's tests. This meta-analysis established that there is a significantly high prevalence of aPLs (i.e., aCL and anti-β2-GPI antibodies) in patients with BD when compared to controls.

Coronary Involvement in Behçet's Disease: what are its Risks and Prognosis? (Rare Cases and Literature Review)

Objective

In our clinic, we aimed to investigate the effect of preoperative risk factors and postoperative complications on reoperation and mortality in cases with Behçet's disease which presents very rare coronary artery involvement.

Methods

Thirteen patients with Behçet's Disease who had undergone coronary artery bypass grafting in our center between 2003 and 2015 were analyzed. We evaluated the clinical and laboratory findings, complications and mortality rates of our patients in light of the literature.

Results

The mean age was 38.5 (30-55; 3 women). The mean time from onset of Behçet's disease to coronary artery disease was 4,7 (3-11) years. Fifty-four percent of the patients were asymptomatic. Coronary artery disease of these was exposed while peripheral vascular surgery was planned due to complications of Behçet's disease. Symptomatic patients presented angina pectoris (31%), acute coronary syndrome (8%) and arrhythmia (8%). In coronary pathology of patients, distal type obstruction (31%), aneurysm and pseudoaneurysm (31%), proximal segment thrombus (15%), chronic type stenosis and occlusions (31%) were present. Early mortality (15%) was due to acute myocardial infarction while the late mortality (15%) was due to cerebral and gastrointestinal bleeding. Reoperation was due to bleeding in one case on the 1st postoperative day and due to acute pulmonary embolism in another case in the 3^rdpostoperative year.

Conclusion

In Behçet's disease, coronary artery bypass grafting is a procedure with high mortality, especially in the acute period. The on-pump surgery technique in these cases can be safely performed for multiple bypasses and in patients above 40 years old.

Lessons of the month 2: A case of Behçet's disease: 70% have ophthalmic involvement

A 34-year-old man presented to the emergency department with acute painless loss of vision of the left eye. Past medical history included painful lumps in the legs and frequent mouth ulcers, which were undiagnosed. The patient's visual acuity was 6/5 and counting fingers in the right and left eye, respectively. There were extensive intraretinal haemorrhages and venous sheathing in the superior quadrant of the left eye with associated disc oedema. The case was discussed in a multidisciplinary team meeting in the presence of ophthalmology, dermatology and immunology and a diagnosis of Behçet's disease was reached. The patient was commenced on intravenous methylprednisolone for 3 days followed by a switch to oral prednisolone. Due to recalcitrant uveitis, an intravitreal dexamethasone implant was administered. Eventually, systemic azathioprine and infliximab were commenced with frequent review by ophthalmology and immunology. The macular oedema improved but, unfortunately, the patient's visual acuity did not recover. Behçet's disease is a complex vasculitis involving multiple organ systems. Ocular manifestations can occur in 70% of patients, comprising retinal vasculitis, anterior uveitis, iridocyclitis, chorioretinitis, scleritis, keratitis, vitreous haemorrhage, optic neuritis, conjunctivitis, retinal vein occlusion and retinal neovascularisation. A tailored multidisciplinary approach is required, with corticosteroids being the mainstay of treatment.

Isolated brachial artery aneurysm successfully treated with a covered stent in a patient with Behçet's disease

Behçet's disease is a vasculitic pathology characterized by skin lesions, genital ulcers, aphthous stomatitis, and uveitis. Arterial aneurysms are rare in this disease. Herein, we report a rare case of an isolated brachial artery aneurysm with a history of Behçet's disease treated with endovascular covered stenting of the brachial artery.

The Challenge of Treating Pulmonary Vasculitis in Behçet Disease: Two Pediatric Cases

Behçet disease (BD) is a multisystemic autoinflammatory disorder characterized by recurrent mucocutaneous, ocular, musculoskeletal, gastrointestinal, central nervous system, and vascular manifestations. Pulmonary arterial involvement (PAI) of BD is probably the most severe form of vasculitis, at least in children. PAI has a high mortality, morbidity, and recurrence rate. There are limited data regarding treatment and outcomes of pediatric patients with BD with PAI. Herein, we report 2 pediatric patients with BD presented with hemoptysis and support our data with a systematic review. These patients were given immunosuppressive therapy, which covered pulse methylprednisolone followed by oral prednisolone, intravenous cyclophosphamide every 3 weeks for a total of 6 cycles, and interferon-α2a concomitantly. These are the first reported cases in the literature successfully treated with this treatment modality in a complication with 50% mortality. These patients have been followed up for a period of at least 4 years without any vascular recurrence. Pediatricians should be aware that patients with BD may not present with full diagnostic criteria. They should consider BD in a child with PAI to avoid diagnostic delay and start life-saving accurate immunosuppressive treatment.

Early Massive Pulmonary Embolism After Total Hip Arthroplasty in a Patient With Behcet Disease: A Case Report

Venous complications in Behcet disease (BD) affect nearly 40% of patients. We describe a woman with BD who presented with a massive bilateral pulmonary embolism 30 hours after total hip arthroplasty. The patient underwent surgical thrombectomy and venoarterial extracorporeal membrane oxygenation. Methotrexate was withheld 15 days before surgery and restarted on postoperative day 2. Immunosuppressive therapy, such as methotrexate, appears to be the most effective prophylactic treatment for venous thrombosis in patients with BD, whereas prophylaxis with low-molecular-weight heparin may be ineffective, as was the situation in our patient. Therefore, continuation of methotrexate perioperatively should be considered in patients with BD. Systematically performing preoperative deep vein thrombosis screening should be also considered. The patient also had diabetes mellitus treated with metformin and sitagliptin preoperatively.

Neuro-Behçet Disease in the Central University Hospital of Asturias

OBJECTIVE

To describe the frequency and profile of patients with neuro-Behçet's disease (NBD) at the Central University Hospital of Asturias between 1981 and June 2018.

PATIENTS AND METHODS

Retrospective study including epidemiological, clinical, neuroimaging, cerebrospinal fluid (CSF) study, histopathology, treatment and evolution characteristics. Clinical characteristics are differentiated between patients with Behçet without neurological affectation and NBD.

RESULTS

We found 10 cases of NBD (25.6%). The mean age was 29.7years, and it was more frequent in males. Sixty percent had parenchymal involvement. The non-parenchymal involvement included a case with cerebral venous thrombosis and two cases with isolated aseptic meningitis. Findings of vasculitis were found on cerebral magnetic resonance imaging, and alteration in the biochemistry of the CSF. One patient presented a striking motor disability. Ocular involvement was greater in the group of patients without neurological involvement (P=0.009).

CONCLUSIONS

NBD is a relatively frequent presentation, especially in males and in the parenchymal form. We did not find a systemic clinical marker of neurological involvement.

Multiple Overlapping Stent Implantation Combined with Coil Embolization for a Suprarenal Aortic Pseudoaneurysm with Impending Rupture in a Patient with Behçet's Disease

Behçet's disease is an autoimmune vasculitis, which mainly manifests as aneurysm when arteries are involved. Treatments including graft interposition or stent-graft implantation are best performed after active inflammation subsides, otherwise there will be complications such as anastomotic pseudoaneurysms and graft occlusion. We report the treatment of a suprarenal abdominal aortic pseudoaneurysm in a patient with Behçet's disease via multiple overlapping stent implantation combined with coil embolization which was performed in a subacute fashion because of impending rupture of the pseudoaneurysm. She was maintained on long-term immunosuppressive therapy and remained symptom free at 2-year follow-up.

Clinical course of abdominal aortic aneurysms in Behçet disease: a retrospective analysis

Arterial aneurysms are rare manifestations of Behçet Disease (BD) with high morbidity and mortality. This study aimed to investigate the clinical course of BD patients with abdominal aortic aneurysms (AAA). We retrospectively searched charts of BD patients, followed up between 1988 and 2011, to identify those with AAA with at least 6-month clinical and radiological follow-up data. Chart review revealed 12 patients (11 males) with AAA amongst 1224 patients; follow-up data from 11 patients were available. The most common symptoms were lower back and abdominal pain. The only pre-treatment complication was a spontaneous rupture. All but one patient received corticosteroid and cyclophosphamide pulses for the induction, and corticosteroid and azathioprine for the maintenance treatment; one patient received only the maintenance treatment. Two patients had surgical graft interposition, without postoperative complications. Seven patients had endovascular stenting; five of them (71.4%) showed radiological regression after 32.5 (13.4-53.8) months, while four (57%) had clinical improvement after 11.8 (0.2-29.4) months. However, one non-responsive patient developed stent infection and exsanguinated during percutaneous drainage, and one patient developed femoral artery pseudo-aneurysm at the catheter insertion site. Another patient developed a new aneurysm under the maintenance treatment. Medical treatment alone yielded radiological regression in one of two patients. Current immunosuppressive, surgical or endovascular approaches can provide clinical and radiological improvements lately in BD patients with AAA. Furthermore, complication rates seem to be high with interventional approaches. These findings suggest an unmet need for safer alternative treatments.

Venous vessel wall thickness in lower extremity is increased in male patients with Behcet's disease

Vascular involvement, especially in young males, is seen in up to 40% of the patients with Behcet's disease (BD) and is a major cause of mortality and morbidity. In this study, we investigated vessel wall thickness (VWT) and dilatation in lower extremity veins with Doppler ultrasound (US) in male BD patients. Sixty-one male patients with BD, 37 healthy male controls (HC) and 27 male patients, with ankylosing spondylitis (AS), were included in the study. Venous Doppler US was performed by an experienced radiologist blinded to cases. Bilateral common femoral vein (CFV) wall thickness and great/small saphenous vein (SV) dilatations were assessed. All venous measurements were significantly higher in BD compared to AS and HC (p < 0.001 for all). Both right and left extremity CFV thicknesses had a high area under the ROC curve (> 0.8). Cut-off values for right and left CFV thicknesses for BD was 0.49 and 0.48 mm, respectively. High sensitivity and specificities are observed for both measurements (right CFV: sensitivity 81%, specificity 78.4%; left CFV: sensitivity 82.8%, specificity 81.1%). We found increased CFV thickness in BD patients independent of vascular involvement. As a similar change was not observed in controls, increased CFV thickness may be a specific sign of venous inflammation in BD. Our acceptable sensitivity and specificity values of CFV measurements suggest that assessment of femoral vein thickness with US may be a candidate diagnostic tool, especially in young males suspected of BD.

Emergent stent-graft repair of a massive aortic pseudoaneurysm secondary to Behçet's disease in a child

An 11-year-old male with vasculitis was found to have a large abdominal aortic pseudoaneurysm on diagnostic angiography. This report describes endovascular repair of the pseudoaneurysm by stent-graft exclusion. The existing literature surrounding this rare and potentially fatal condition is also reviewed.
