Behçet’s disease and cardiovascular involvement

Cutting-Edge Strategies for Renal Tumour-like Lesions in Granulomatosis with Polyangiitis: A Systematic Review

BACKGROUND

Granulomatosis with polyangiitis (GPA) is characterised by granulomatous inflammation and small-to-medium vessel necrotising vasculitis, mainly affecting respiratory tract and kidneys. Renal involvement presenting as tumour-like lesions poses diagnostic and treatment challenges.

METHODS

Following the observation of a GPA patient presenting with multiple renal tumour-like lesions, we conducted a systematic literature review on MEDLINE/PubMed, EMBASE, and Cochrane databases. Data gathered from the literature were analysed to summarise the diagnostic approach, management, and outcome of renal GPA-related tumour-like lesions.

RESULTS

a 49-year-old female presented with persistent constitutional symptoms and multiple bilateral renal lesions. Renal biopsy showed chronic interstitial inflammation with necrotising granulomas. Laboratory tests disclosed positive anti-proteinase 3 (PR3) anti-neutrophil cytoplasmic antibody (ANCA) leading to a final diagnosis of GPA. She was effectively treated with high-dose glucocorticoids and rituximab. Literature search yielded 41 articles, concerning 42 GPA patients with renal masses, presenting bilaterally in 23.8% of the cases. Positive PR3-ANCA was observed in 86.5% of the cases. Half of 42 patients showed kidney abnormalities. Treatment with glucocorticoids (83.3%) and immunosuppressive agents (80.9%) resulted in an overall good remission rate and favourable prognosis.

CONCLUSIONS

GPA should be considered in the differential diagnoses of kidney tumour-like lesions. The diagnosis is challenging, and histological examination greatly contributes to the diagnostic work-up.

Risk factors of cardiovascular involvement in patients with Behcet's disease

Objectives

Behcet's disease (BD) is a multi-systemic inflammatory vasculitis which may be life-threatening if combined with cardiovascular problems. The aim of the study was to identify potential risk factors associated with cardiovascular involvement in BD.

Methods

We reviewed the medical databases of a single center. All BD patients identified as fulfilling the 1990 International Study Group criteria or the International Criteria for Behcet's Disease criteria. Cardiovascular involvement, clinical manifestations, laboratory features, and treatments were recorded. The relationship between parameters and cardiovascular involvement was analyzed.

Results

111 BD patients were included: 21 (18.9%) had documented cardiovascular involvement (CV BD group) and 99 (81.1%) had no cardiovascular involvement (non-CV BD group). Compared with non-CV BD, the proportion of males and smokers were significantly increased in CV BD (p = 0.024 and p < 0.001, respectively). Levels of activated partial thromboplastin time (APTT), cardiac troponin I and C-reactive protein were significantly higher (p = 0.001, p = 0.031, and p = 0.034, respectively) in the CV BD group. Cardiovascular involvement was associated with smoking state, the presence of papulopustular lesions, and higher APTT in multivariate analyzed (p = 0.029, p = 0.021, and p = 0.006, respectively). The ROC curve showed that APTT predicts the risk of cardiovascular involvement (p < 0.01) at a cut-off value of 33.15 s with a sensitivity of 57.1% and specificity of 82.2%.

Conclusion

Cardiovascular involvement in BD patients was associated with gender, smoking state, the presence of papulopustular lesions, and higher APTT. All patients newly diagnosed with BD should be systematically screened for cardiovascular involvement.

Potential Utility of Oral Mucosal Capillaroscopy as an Indicator of Microvascular Damage in Behçet Disease: A Preliminary Study

Introduction

Behçet disease (BD) is an auto-inflammatory condition characterized by multisystemic vasculitis. Oral mucosal capillaroscopy is an easy-to-use, repeatable, non-invasive method for evaluating mucosal microvasculature, contributing to the differential diagnosis and prognosis of various acute and chronic inflammatory diseases.

Objectives

This study aims to characterize and describe the oral labial mucosal capillary findings in patients with BD using handheld dermatoscopy and to investigate the relationship between the capillary findings and the severity of the disease.

Methods

This cross-sectional study included patients with BD and healthy subjects. Capillaroscopic examination of the oral labial mucosa in each subject was performed by a handheld dermatoscope using polarized light. The clinical severity of BD was evaluated using Krause's Clinical Severity Scoring for BD.

Results

Sixty patients with BD and 60 healthy subjects were enrolled in the study. The frequencies of irregular capillaries, microhemorrhages, glomerular vessels, megacapillaries, and tortuous vessels were statistically significantly higher in the patient group when compared to the healthy individuals. In addition, a correlation was detected between the oral mucosal capillaroscopic findings and disease duration, severity, and vascular complications.

Conclusions

Our study is the first to explore the potential role of oral mucosal capillaroscopic examination in patients with BD. Data obtained from this study indicated that oral mucosal capillaroscopy may be a useful tool to demonstrate microvascular damage in patients with BD.

Fragmented QRS complexes are associated with subclinical left ventricular dysfunction in patients with Behcet's disease: Four-dimensional speckle tracking echocardiography

BACKGROUND

Behcet's disease (BD) is a chronic systemic inflammatory disease in which early detection of cardiac involvement is essential. The aim of this study was to assess the left ventricular (LV) functions in BD patients using four-dimensional (4D) speckle tracking echocardiography (STE) and to test the correlation between LV dysfunction and the presence of QRS fragmentation.

METHODS

This cross-sectional study included 64 Behcet's patients and 48 healthy volunteers. The BD group was divided into two subgroups depending on the presence (fQRS+) or absence (fQRS-) of fragmented QRS (fQRS). In both groups, left ventricular global area strain (LV-GAS), global radial strain (GRS), global longitudinal strain (GLS), and global circumferential strain (GCS) were obtained with 4D echocardiography.

RESULTS

GAS, GRS, GLS, and GCS values were significantly different in Behcet's patients and in healthy volunteers. GLS and GAS values were lower in the fQRS+ than in the fQRS- group (-15.8 ± 1.8 and -17.9 ± 1.6, P = .001 vs -25.0 ± 3.1 and -29.2 ± 4.2, P < .001, respectively). The duration of disease was longer in fQRS+ than in fQRS- patients (120.8 ± 67.4 vs 71.0 ± 40.5, P < .001). Multiple linear regression analysis showed that fQRS and disease duration were independent predictors of LV-GAS.

CONCLUSIONS

Four-dimensional STE may be helpful for the prediction of early cardiac dysfunction in patients with BD. The presence of fQRS may be an indicator of subclinical LV dysfunction.

A right ventricular mass in a young man with Behçet's disease: A case report

Behçet's disease (BD) is a rarely seen immune disease with multiple systems involvements. Among them, a cardiac manifestation is a severe and rare complication of BD. Here we reported a young man with BD, complicated with a right ventricular thrombus. Surgery was performed successfully to remove the intracardiac thrombus, and a 2-year follow-up failed to find any new symptoms and pathological findings. Our experience provided a better example for diagnosing and early surgical treatment for intracardiac thrombus of BD.

Cardiac involvement in the adult primary vasculitides

INTRODUCTION

Heart involvement in vasculitis is rare, but potentially severe. The ascertainment of cardiac disease in vasculitis is complex and requires an integrated multidisciplinary approach involving the Rheumatologist, Radiologist, Cardiologist, and Heart surgeon.

AREAS COVERED

the authors searched PubMed using the keywords 'heart'[Mesh] and vasculitis"[Mesh].

EXPERT OPINION

Virtually any vasculitis can affect the heart, but cardiac involvement is more common in some vasculitides such as Takayasu arteritis, polyarteritis nodosa, and eosinophilic granulomatosis with polyangiitis. Immunosuppressive treatment and when indicated surgery can improve the prognosis.

Cutaneous and Extracutaneous Manifestations of Behçet's Disease Linked to Its Disease Activity and Prognosis

Background

Behçet’s disease is a potentially fatal vasculitis disorder involving vessels in both the arterial and venous systems. Cutaneous manifestation is the most common sign in Behçet’s disease, but its relation to disease activity and prognosis is lacking.

Objective

Our study aims to determine the relationship between cutaneous, extracutaneous manifestations with Behçet’s disease activity, morbidity, and mortality.

Materials and Methods

Patients diagnosed with Behçet’s disease were identified by using the 1990 International Study Group for Behçet’s disease criteria and/or the 2014 international criteria for Behçet’s disease. Data regarding patients’ clinical manifestations, laboratory results, disease activity, and prognosis were retrieved and analyzed. Disease activity was evaluated using the 2006 Behçet’s disease current activity form (BDCAF).

Results

Of 119 patients, the mean age at diagnosis was 35.7 ± 10.7 years and 60% were female. Median disease duration was 96 months (IQR 48–168). Minor oral ulcer at the buccal mucosa was associated with lower median BDCAF score (p = 0.003), whereas minor oral ulcer at the tonsil was related to higher BDCAF score (p = 0.024). Male gender was associated with higher cumulative dose of corticosteroids (p = 0.003) and hospitalization (OR = 2.89 (95% CI [1.10, 7.57]), p = 0.031). Ocular manifestations were related to higher dose of corticosteroids (p = 0.002) and morbidity (OR = 4.39 (95% CI [1.57, 12.29]), p = 0.005).

Conclusion

Our study suggests that different locations of minor oral ulcers help predict disease activity. Male gender and the presence of ocular manifestations resulted in less favorable outcomes for Behçet’s disease.

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.

The epithelial immune microenvironment (EIME) in atopic dermatitis and psoriasis

The skin provides both a physical barrier and an immunologic barrier to external threats. The protective machinery of the skin has evolved to provide situation-specific responses to eliminate pathogens and to provide protection against physical dangers. Dysregulation of this machinery can give rise to the initiation and propagation of inflammatory loops in the epithelial microenvironment that result in inflammatory skin diseases in susceptible people. A defective barrier and microbial dysbiosis drive an interleukin 4 (IL-4) loop that underlies atopic dermatitis, while in psoriasis, disordered keratinocyte signaling and predisposition to type 17 responses drive a pathogenic IL-17 loop. Here we discuss the pathogenesis of atopic dermatitis and psoriasis in terms of the epithelial immune microenvironment-the microbiota, keratinocytes and sensory nerves-and the resulting inflammatory loops.

Cardiac findings in patients with Behçet's disease: Facts and controversies

Behçet’s disease (BD) is a systemic vasculitis of unknown etiology. It is characterized by recurrent oral and genital ulcers, uveitis, and a number of systemic manifestations. Although the disease is recognized worldwide, its prevalence is highly variable. A detailed review and analysis of the worldwide published reports on BD showed that not only the prevalence of the disease but also its cardiac complications differ according to the geographic distribution of the studied population. With the exception of France, Greece, Spain, and Italy, very few reports and studies regarding BD have been published from the western countries. Cardiovascular complications are an important cause of poor outcome in patients with BD. Over the past few years, many case reports and studies have been published, providing more facts about these complications. For example, peculiar echocardiographic findings in patients with aortic valve regurgitation and intracardiac thrombi secondary to BD were recently described. The role of these findings in the initial diagnosis of the disease, however, remains to be evaluated. On the other hand, some reports present contradictory results, especially concerning the left ventricular diastolic function, pathogenesis of coronary artery disease, and proper management of the cardiac complications in BD. Importantly, management of these complications is based mainly on the discretion of the treating physician due to the absence of large controlled studies and clear guidelines. This approach sometimes creates inconsistent data and allows controversies to persist. The review presented here will discuss some of the facts and controversies related to cardiac complications in BD.

Serum uric acid could be served as an independent marker for increased risk and severity of ascending aortic dilatation in Behçet's disease patients

OBJECTIVE

This study aimed to investigate the correlation of serum uric acid (SUA) with risk and dilatation diameter of ascending aortic dilatation (AAD) in Behçet's disease (BD) patients.

METHODS

Seventeen BD patients complicated with AAD and 20 BD patients without AAD were consecutively enrolled and categorized into AAD group and control group, respectively. Ascending aortic dilatation was determined by two-dimensional doppler echocardiographic examination, and AAD was defined as a diameter of ascending aorta ≥3.8 and <4.4 cm. SUA was detected by quantitative immunoassay method.

RESULTS

Ascending aortic dilatation patients presented with higher proportion of male patients (P = 0.003), hypertension occurrence (P = 0.036) and increased diameter of ascending aorta (P < 0.001) compared to controls. SUA was elevated in AAD patients compared to controls (P = 0.002), and receiver operating characteristic curve displayed that SUA presented with great predictive value for AAD risk in BD patients with area under curve (AUC) 0.821 (95% CI 0.675-0.966). Pearson's analysis also disclosed that SUA was positively correlated with ascending aortic diameter in total BD patients. However, no difference of CRP (P = 0.219) or ESR (P = 0.320) between AAD patients and controls was observed, and no correlation of CRP (R = -0.150, P = 0.377) or ESR (R = 0.067, P = 0.692) with ascending aortic diameter in total BD patients was discovered either. Further multivariate logistic regression illuminated that SUA was an independent factor predicting AAD risk in BD patients (P = 0.031).

CONCLUSIONS

Serum uric acid could be served as an independent marker for increased risk and severity of AAD in BD patients.

'Clinically suspected myocarditis with pseudoinfarct presentation' complicated with left ventricular aneurysm

A 51-year-old man presented with chest pain, high troponin level, inflammatory syndrome and ST-segment elevation in the anterior leads. While the transthoracic echocardiogram (TTE) showed anteroseptal hypokinesis and apical akinesis, the coronary angiogram was normal. Cardiac MR demonstrated a typical aspect of myocarditis (multiple areas of mid-myocardial late gadolinium enhancement, sparing the subendocardial layer, along with oedema). The initial diagnosis was clinically suspected myocarditis with pseudoinfarct presentation. However, the short-term evolution was not typical of this syndrome, since an apical transmural scar with aneurysm developed within 2 weeks. Seven years later, the patient remained asymptomatic, while Q waves persisted in anterior leads along with an apical aneurysm on TTE. A transmural myocardial necrosis with aneurysm is an unusual complication of acute myocarditis. The potential mechanisms accounting for the development of these lesions are reviewed, and the clinical implications for the diagnosis and monitoring of acute myocarditis are discussed.

Soluble Tumor Necrosis Factor (TNF)-Like Weak Inducer of Apoptosis (Tweak) Independently Predicts Subclinical Atherosclerosis in Behcet's Disease

BACKGROUND

Vasculopathy is a major cause of mortality and morbidity in Behcet's Disease (BD). Subclinical atherosclerosis can even be detected in the early stage of BD. Soluble tumor necrosis factor-like (TNF) weak inducer of apoptosis (TWEAK) is known as a good marker of the inflammation in vascular tree. The aim of this study is to examine the relationship between carotid artery intima-media thickness (cIMT) and serum TWEAK levels in patients with BD.

MATERIALS AND METHODS

In line with International BD Study Group criteria, 48 BD, and 30 controls were included in our study. Disease activity was evaluated according to BD current activity form (BDCAF). C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), lipid parameters, serum TWEAK levels, and cIMT were measured.

RESULTS

Disease activity score of BD patients was found as 2 (range 0-7). cIMT, serum TWEAK, CRP and ESR levels of BD patients were significantly higher comparing to cIMT (0.62 ± 0.13 mm vs. 0.43 ± 0.09 mm, p < 0.001), serum TWEAK (667.5 ± 130.6 vs. 603.4 ± 89.6 pg/ml, p = 0.015), CRP (3.9 ± 4.3 vs. 1.4 ± 1.0 mg/dl, p < 0.001) and ESR (10.2 ± 10.0 vs. 5.6 ± 3.7 mm/h, p = 0.005) levels of the control group. There was a positive correlation between serum TWEAK level and disease activity (r = 0.251, p = 0.030) and cIMT (r = 0.463, p < 0.001). Our study also revealed an independent correlation between cIMT and serum TWEAK levels (beta = 0.354, p < 0.001).

CONCLUSION

Increased serum TWEAK levels can play a part in the development of atherosclerotic heart disease in BD. Due to their liability to atherosclerosis, patients with BD must followed closely.

Serum PLR and LMR in Behçet's disease: Can they show the disease activity?

The aim of this study is to determine platelet to lymphocyte ratio (PLR) and lymphocytes to monocytes ratio (LMR) levels in Behçet's disease (BD) and to investigate their relationships with disease activity.Hematological and inflammatory parameters including high-sensitivity C-reactive proteins (hs-CRP), erythrocyte sedimentation rate (ESR), PLR, and LMR were examined in BD and healthy controls.Data from 140 patients with BD (108 with active and 32 with inactive disease) and 107 controls were enrolled. PLR (153.21 ± 65.44, 106.20 ± 28.91, P <.001, respectively) was remarkably higher, whereas LMR (5.37 ± 5.47, 8.95 ± 5.84, P <.001, respectively) was significantly lower in BD than in controls. Active BD patients had significantly higher PLR (159.20 vs 131.14, P = .037), ESR (38.30 vs 24.55, P = .017), and hs-CRP (30.20 vs 17.21, P = .027) than those with inactive BD. However, no significant difference in LMR was found between the groups. Moreover, PLR was positively correlated with BDCAF (r = 0.193, P <.05), hs-CRP (r = 0.402, P <.01), and ESR (r = 0.284, P <.01), whereas LMR was negatively correlated with BDCAF (r = -0.175, P <.05), hs-CPR (r = -0.263, P <.01), and ESR (r = -0.175, P <.05). Additionally, both PLR and LMR were shown to be independent factors for BD by multivariate logistic regression analysis. Furthermore, a PLR level of 124.63 was determined as the best cut-off value by ROC analysis (sensitivity 64.3%, specificity 78.0%, and the area under the ROC curve 0. 753).PLR was elevated in active BD as compared to inactive BD. PLR may be a reliable, cost-effective, and novel potential parameter to help evaluate disease activity in BD.

Ventricular endomyocardial fibrosis in a pregnant female with Behçet’s disease

A 32-year-old pregnant woman, diagnosed with Behçet’s disease 6 months earlier, presented with recent mild hemoptysis and exertional dyspnea. Transthoracic echocardiography showed an enlarged dysfunctional right ventricle. A large hypoechoic triangular-shaped mass was seen attached to the inner right ventricular wall, filling the cavity. No change in the size of the mass was noted after anticoagulant administration, and right heart failure progressed. Surgery was performed to remove the mass and repair the tricuspid valve. This was a very rare presentation of Behçet’s disease in pregnancy, which resulted in delivery of a completely healthy baby despite corticosteroid pulse therapy and cyclophosphamide.

Assessment of Left Ventricular Diastolic Function in Egyptian Patients With Behçet's Disease

Objectives

This study aims to evaluate left ventricular diastolic function in Egyptian patients with Behçet's disease using variable echocardiographic parameters by combining both transmitral and tissue Doppler velocities to overcome the occasional false interpretation of preload dependent transmitral parameters and to detect the correlation between various left ventricular diastolic parameters and different disease manifestations.

Patients and methods

Forty patients (35 males, 5 females; mean age 31±8 years; range 19 to 52 years) with Behçet's disease and 32 age- and sex- matched healthy controls (26 males, 6 females; mean age 28±6 years; range 19 to 60 years) were enrolled. Left ventricular diastolic function was assessed using an algorithm that combined transmitral and tissue Doppler derived parameters.

Results

Mean disease duration of the patients was 7.4±6 years. Left and right ventricular systolic function was normal in both groups. The transmitral E/A was<1 in six patients (15%). There was no difference between patients and controls regarding the other left ventricular diastolic parameters. Compared to patients with an E/A ratio >1, patients with E/A<1 were significantly older and had a longer disease duration (p=0.001 and p<0.001, respectively). All the other echocardiographic parameters in both groups were comparable.

Conclusion

Egyptian patients with Behçet's disease have normal left ventricular diastolic function regardless of disease duration and activity.

Behçet's disease physiopathology: a contemporary review

Behçet’s disease, also known as the Silk Road Disease, is a rare systemic vasculitis disorder of unknown etiology. Recurrent attacks of acute inflammation characterize Behçet’s disease. Frequent oral aphthous ulcers, genital ulcers, skin lesions and ocular lesions are the most common manifestations. Inflammation is typically self-limiting in time and relapsing episodes of clinical manifestations represent a hallmark of Behçet’s disease. Other less frequent yet severe manifestations that have a major prognostic impact involve the eyes, the central nervous system, the main large vessels and the gastrointestinal tract. Behçet’s disease has a heterogeneous onset and is associated with significant morbidity and premature mortality. This study presents a current immunological review of the disease and provides a synopsis of clinical aspects and treatment options.

Intracardiac thrombus in patients with Behcet's disease: clinical correlates, imaging features, and outcome: a retrospective, single-center experience

Intracardiac thrombus (ICT) is a rare but serious complication of Behcet's disease (BD). The study was to report the clinical characteristics, imaging features, treatment, and outcomes of BD patients with ICT in a single tertiary center. A series of 626 BD patients admitted to Peking Union Medical College hospital between April 2003 and April 2013 were reviewed. A total of 12 (1.9 %) BD patients with ICT were included. ICT was presenting manifestation of BD in 5 of the 12 patients (41.7 %) and occurred mostly in men (9/12, 75 %) younger than 40 years. Patients with ICT had more arterial (66.7 vs. 7.3 %, p < 0.001) and venous involvement (75.0 vs. 8.1 %, p < 0.001) compared to those without ICT. Right heart was the most frequent site of ICT (11/12, 91.7 %). Thrombus were hyperechogenic and immobile with a broad-based attachment on echocardiography in most cases (11/12, 91.7 %). Cardiac magnetic resonance (CMR) was performed in four patients. All thrombi showed isointense on T1-weighted image, while all but one were hypointense on T2-weighted image without delayed enhancement. Remission of ICT was associated with therapy of anticoagulant, corticosteroid, and immunosuppressant in most cases (10/12, 83.3 %). There was no death, and relapses of ICT occurred in only one patient after tapering of immunosuppressant during follow-up. A diagnosis of BD should be considered when a young male patient presents with a mass in the right-sided heart accompanied by vascular lesions. Medical therapy especially adequate immunosuppressants might be the first choice for BD patients with ICT.

Acute myocardial infarction and subclavian artery occlusion in a 41-year-old woman with Behçet's disease: coronary and large vessel arteritis

We report the case of a 41-year-old Chinese woman with Behçet's disease (BD) complicated by acute myocardial infarction, requiring inotropic and ventilatory support. Angiography showed critical left anterior descending coronary artery stenosis, a blocked left subclavian artery and left carotid artery stenosis. The patient was successfully treated with a high dose of immunosuppressants, standard anti-ischaemic therapy and percutaneous coronary intervention. Although life-threatening, coronary arteritis is a treatable manifestation of BD. We suggest that the diagnosis of coronary arteritis be considered in patients with BD who present with chest pain. Involvement of other arteries should also be looked out for in these patients.

Cardiovascular Involvement in Behçet Disease: Clinical Implications

Behçet disease (BD) is a multisystem disorder, with vasculitis as its underlying pathological process, in contrast to the classic triad of recurrent oral and genital ulcerations, with uveitis. Vascular involvement in BD includes venous thrombosis, arterial occlusion, and pulmonary artery and aortic aneurysm formation. Cardiac involvement is rare and often obscure. It includes intracardiac thrombi formation, and is associated with a poor prognosis. Our objectives are to describe two cases with BD, complicated with vascular and cardiac involvement, and to raise awareness of these rare complications, the needed routine surveillance, and thus to prevent inappropriate interventions, serious outcomes, and mortality. We present two male patients from the Mediterranean Basin with BD. The first was diagnosed early as a BD patient. The second was diagnosed at the time of cardiovascular (CV) involvement. We recommend that patients who are diagnosed, or even suspected of suffering from BD, especially in endemic areas along the Silk Route pathway, should be followed up routinely for CV involvement, even if rare, obscure, or with a bizarre presentation.

Value of certain echocardiographic findings in the initial suspicion of Behçet's disease

PURPOSE

To describe the echocardiographic findings detected as first manifestations of Behçet's disease (BD) and compare these findings with those detected in established cases of BD receiving regular medical treatment.

METHODS

Two groups of patients were studied. Group 1 comprised 41 patients with BD on regular medical treatment. Group 2 comprised 5 previously healthy patients who presented to the cardiology department because of cardiac symptoms and were diagnosed in retrospect during hospitalization as BD. Thirty-two age- and sex-matched individuals served as control subjects (control group). All patients and controls underwent complete M-mode, two-dimensional, and Doppler transthoracic echocardiographic examinations.

RESULTS

Of the 41 treated patients with BD (mean age: 32 ± 8 years, 90% males, mean duration since diagnosis: 14.5 years), only 1 patient was found to have severe aortic regurgitation secondary to aortic root dilation. On the other hand, the 5 previously healthy patients who presented with cardiac symptoms (mean age: 24 ± 6 years, all males) had significant cardiac involvement and evident echocardiographic findings (P < 0.001). Four cases had intracardiac masses: 3 in the right atrium (RA), 1 in the right ventricle (RV), while the last patient had pericardial effusion (PE). All these patients were diagnosed in retrospect as BD. The RA masses disappeared on medical therapy, while the RV mass was surgically excised and proved to be multiple thrombi histopathologically. The patient with PE had recurrent attacks of massive effusion so a pericardial window was performed surgically.

CONCLUSION

Diagnosis of BD might be initially suspected by the cardiologists based on certain echocardiographic findings, namely the presence of right-sided masses. Diagnosis of BD in such patients has important therapeutic implications and accordingly prognostic value.

Thrombosis in vasculitis: from pathogenesis to treatment

In recent years, the relationship between inflammation and thrombosis has been deeply investigated and it is now clear that immune and coagulation systems are functionally interconnected.

Inflammation-induced thrombosis is by now considered a feature not only of autoimmune rheumatic diseases, but also of systemic vasculitides such as Behçet’s syndrome, ANCA-associated vasculitis or giant cells arteritis, especially during active disease.

These findings have important consequences in terms of management and treatment. Indeed, Behçet’syndrome requires immunosuppressive agents for vascular involvement rather than anticoagulation or antiplatelet therapy, and it is conceivable that also in ANCA-associated vasculitis or large vessel-vasculitis an aggressive anti-inflammatory treatment during active disease could reduce the risk of thrombotic events in early stages.

In this review we discuss thrombosis in vasculitides, especially in Behçet’s syndrome, ANCA-associated vasculitis and large-vessel vasculitis, and provide pathogenetic and clinical clues for the different specialists involved in the care of these patients.

Recurrent right atrial thrombosis due to Behçet disease

Behçet disease is a rare condition sometimes associated with chronic cardiac inflammation followed by myocardial dysfunction and vascular inflammation. We report a case of recurrent right atrial thrombus due to Behçet disease despite continued anticoagulation therapy. The thrombus disappeared after the initiation of immunosuppressive therapy. To avoid a progression to thrombus or cardiac dysfunction in this recurrent case, the early identification of cardiac involvement of Behçet disease using echocardiography and/or cardiac magnetic resonance imaging might be important. Combined immunosuppressive therapy with prednisone and cyclophosphamide might be needed to treat recurrent thrombosis due to Behçet disease.

Effectiveness and tuberculosis-related safety profile of interleukin-1 blocking agents in the management of Behçet's disease

Behçet's disease (BD) is a multi-systemic disorder of unknown etiology characterized by relapsing oral-genital ulcers, uveitis, and involvement of the articular, gastrointestinal, neurologic, and vascular systems. Although the primum movens of this condition remains unknown, a tangled plot combining autoimmune and autoinflammatory pathways has been hypothesized to explain its start and recurrence. In-depth analysis of BD pathogenetic mechanisms, involving dysfunction of multiple proinflammatory molecules, has opened new modalities of treatment: different agents targeting interleukin-1 have been studied in recent years to manage the most difficult and multi-resistant cases of BD. Growing experience with anakinra, canakinumab and gevokizumab is discussed in this review, highlighting the relative efficacy of each drug upon the protean BD clinical manifestations. Safety and tolerability of interleukin-1 antagonists in different doses have been confirmed by numerous observational studies on both large and small cohorts of patients with BD. In particular, the potential for Mycobacterium tuberculosis reactivation and tuberculosis development appears to be significantly lower with interleukin-1 blockers compared to tumor necrosis factor-α inhibitors, thus increasing the beneficial profile of this approach.

Behçet's disease, echocardiographers, and cardiac surgeons: together is better

Behçet's disease is an inflammatory disorder of unknown etiology, characterized by recurrent oral aphthous ulcers, genital ulcers, uveitis, and skin lesions. Many abnormal echocardiographic findings have been previously reported in patients with Behçet's disease. Some of these; namely, aortic root dilation, aortic valve regurgitation, intracardiac thrombi, and pulmonary artery aneurysm may precede other manifestations of the disease and occasionally require surgical intervention for proper management. Compared to patients without Behçet's disease, management of these complications in patients with the disease is challenging and requires different treatment strategies. If diagnosis of Behçet's disease is missed prior to surgical intervention, higher incidence of surgical failure, recurrence, and even higher postoperative mortality may occur. In this review, the author discusses these major cardiac complications of Behçet's disease.

Behçet's Disease and Intracardiac Thrombosis: A Report of Three Cases

We present three patients with Behçet's disease associated with intracardiac thrombus and pulmonary vascular involvement. One of these patients had also Budd-Chiari syndrome. All patients were treated with corticosteroid plus monthly intravenous cyclophosphamide as first line treatment and with no recurrences. Immunosuppressive therapy was successful in the treatment of intracardiac thrombus and also in the regression of pulmonary vascular thromboses in these patients. Intracardiac thrombus in Behçet's disease is rarely seen. Behçet's disease should be remembered in the differential diagnosis of the patients with intracardiac mass, especially in patients from the Mediterranean and Middle East populations.

Rheumatological findings in candidates for valvular heart surgery

Background and Objectives. Valvular heart diseases are among the frequent causes of cardiac surgery. Some patients have a well-known rheumatic condition. Heart valves are fragile connective tissues which are vulnerable to any systemic autoimmune diseases. This study was designed to evaluate the frequency of rheumatological background in patients candidate for valvular heart surgery in Afshar Cardiovascular Center, Yazd, Iran. Methods. One hundred and twenty (120) patients candidate for valvular heart surgery were selected for this study. Careful history and physical examination were undertaken from rheumatological stand points. The most sensitive screening serologic tests were also assayed. Results. The result of this study showed that 53.3% were male and 46.6% were female with mean age of 48.18 ± 17.65 years old. 45.8% of the patients had history of nonmechanical joint disease, 14.2% had history of rheumatological conditions in their family, and 30% had history of constitutional symptoms. 29.8% had positive joint dysfunction findings in their physical examination while 25.8% had anemia of chronic disease. Positive Rheumatoid factor (RF), anticyclic citrullinated peptide (CCP, ACPA), C-reactive protein (CRP), antinuclear antibody (ANA), abnormal urine and elevated erythrocyte sedimentation rate (ESR) were 34, 2.5, 26.7, 4.2, 5, and 36.7%, respectively. Antineutrophil cytoplasmic antibody (ANCA) and antiphospholipid (APL) were positive in a few cases. Conclusion. The findings of this study show immunologic bases for most patients with valvular heart diseases candidate for surgery. Undifferentiated connective tissue diseases may play an important role in the pathophysiology of valvular damage.

Behcet's Disease: New Concepts in Cardiovascular Involvements and Future Direction for Treatment

Behcet's disease (BD) is the only systemic vasculitis involving both arteries and vein in any sizes. It frequently encounters in rheumatology clinics. It has some major morbidities and even fatal outcomes in some cases. The aim of this paper is to analyze the main concepts on pathophysiology and treatment options in BD, focusing on cardiovascular aspects, thrombosis, and potential future treatment.

Spectrum of cardiac lesions in Behçet disease: a series of 52 patients and review of the literature

Cardiac abnormalities in patients with Behçet disease (BD) include pericarditis, myocarditis, endocarditis with valvular regurgitation, intracardiac thrombosis, endomyocardial fibrosis, coronary arteritis with or without myocardial infarction, and aneurysms of the coronary arteries or sinus of Valsalva. Data regarding the clinical spectrum, prevalence, and outcome of cardiac lesions in BD are lacking. In this study, we report the main characteristics, treatment, and long-term outcomes of 52 patients with cardiac lesions from a cohort of 807 (6%) BD patients. Forty-five (86.5%) patients were male, with a mean (±SD) age at BD diagnosis of 29.3 ± 10.3 years.Cardiac involvement was the first feature of BD in 17 (32.7%) patients. Cardiac lesions included pericarditis (n = 20; 38.5%), endocarditis (mostly aortic insufficiency) (n = 14; 26.9%), intracardiac thrombosis (n = 10; 19.2%), myocardial infarction (n = 9; 17.3%), endomyocardial fibrosis (n = 4; 7.7%) and myocardial aneurysm (n = 1; 1.9%). Patients with cardiac involvement were more frequently male (86.5% vs. 64.9%; p < 0.01) and had more arterial (42.3% vs. 11.1%; p < 0.01) and venous lesions (59.6% vs. 35.8%; p < 0.01) compared to those without cardiac manifestations. Factors associated with complete remission of cardiac involvement were treatment regimens with oral anticoagulants, immunosuppressants, and colchicine. The 5-year survival rate was 83.6% and 95.8% (p = 0.03) in BD patients with and without cardiac involvement, respectively. After a median (Q1-Q3) follow-up of 3.0 (1.75-4.2) years, 8 patients had died, in 3 cases directly related to cardiac involvement.In conclusion, cardiac lesions affected 6% of our large cohort of BD patients. The prognosis of cardiac involvement in BD is poor and improves with oral anticoagulation, immunosuppressive therapy, and colchicine.

Aseptic Endocarditis in Behçet's Disease Presenting as Tricuspid Valve Stenosis

Aseptic endocarditis is an uncommon complication of Behçet's disease (BD). We describe a rare case of a 39-year-old female who had BD with aseptic endocarditis of the tricuspid valve (TV) presenting as tricuspid stenosis. She was diagnosed with BD four years ago. The mucocutaneous lesions were well-controlled with colchicine and short courses of corticosteroids. She remained free of signs and symptoms of BD for one year without any medication. Three months before admission, she gradually developed dyspnea on exertion and peripheral edema. Echocardiography revealed dilated right atrium and markedly thickened TV with severe stenosis. TV replacement was performed. Pathologic examination of the valve showed fibrinoid necrotic material and inflammatory cell infiltration. Blood cultures and cultures of the excised valve were negative for microorganisms.

Cardiovascular Behçet's Disease Presenting as a Subepicardial Hematoma: An Uneventful 2-Year Clinical Course

Cardiovascular involvement in Behçet's disease is not uncommon and could be life-threatening. We describe here a 28-year-old man, who developed sudden onset chest pain during warfarinization due to deep vein thrombosis. Echocardiography and computed tomography showed a 60×60 mm-sized hematoma in the pericardial space compressing the right heart. Coronary angiography showed totally occluded proximal right coronary artery. The hematoma was located at the subepicardial plane of the right atrium on surgical view and successfully evacuated. Follow-up echocardiography revealed complete resolution of the hematoma. He is doing well for 24 months after surgery.

Elevated Oxidative Stress Markers and its Relationship With Endothelial Dysfunction in Behçet Disease

Behçet’s disease (BD) is a multisystemic disorder characterized by endothelial dysfunction. However, the relationship between oxidative stress and endothelial function has not been clearly shown. We investigated the relationship between oxidative stress markers and endothelial function in patients with BD. Patients with BD (n = 40) having active disease and sex- and age-matched 40 controls were included. Endothelial function was assessed by flow-mediated dilatation (FMD) technique. Serum gamma-glutamyltransferase (GGT) and high-sensitive C-reactive protein levels (hsCRP) were measured in all participants. Brachial artery FMD was significantly lower in patients with BD than in controls. Gamma-glutamyltransferase and hsCRP levels were higher in patients with BD than in controls. Also, GGT and hsCRP levels were inversely correlated with endothelial function. Oxidative stress markers are elevated in patients with BD having active disease. This may be one of the reasons behind the vasculitis in active BD.

Celiac artery aneurysm repair in Behcet disease complicated by recurrent thoracoabdominal aortic aneurysms

Behçet's disease is a chronic, relapsing multisystemic inflammatory disorder characterized by recurrent orogenital aphthous ulcers, uveitis, and skin lesions. Vascular involvement occurs in up to 38% of these patients. Herein, we report a 19-year-old male who initially presented with an isolated celiac artery aneurysm that was treated with open surgical repair. The patient was subsequently diagnosed with Behçet's disease after the development of oral aphthous ulcers and multiple recurrent postoperative deep venous thromboses and thoracoabdominal arterial aneurysms. Ultimately, a hybrid approach was undertaken. This is the fifth celiac artery aneurysm ever reported in this patient group and the first to present with an isolated celiac artery aneurysm as the initial manifestation of Behçet's disease.

Misdiagnosis of Behçet's disease with unknown protracted fever and chill after surgical excision of cardiac tumor

Behçet's disease involving the heart is extremely rare. Sometimes it is probable to misdiagnose as infective endocarditis when protracted fever and chill occurs. We report a case of protracted pyrexia of unknown origin after surgical excision of a cardiac tumour. Clinically and pathologically a diagnosis of infective endocarditis was probable but antibiotics had no effect. After case review the diagnosis of Behçet's disease was established and the patient was treated with glucocorticoids which resulted in resolution.

Endocardial fibroelastosis of the right ventricle and tricuspid valve in a young adult with Behcet's disease

Endocardial fibroelastosis is characterized by massive proliferation of collagenous and elastic tissue, in which the pathological process is restricted to the endocardium. In this report, we present the case of a 20-year-old man with Behcet's disease and endocardial fibroelastosis of the right ventricle involving tricuspid valve resulting in a tumor mass that was resected along with tricuspid valve replacement. The clinical and pathological features of this rare entity are reviewed.

Behçet's Disease as a Model of Venous Thrombosis

Behçet's disease (BD) is a chronic inflammatory disease of unknown aetiology characterized by recurrent oral, genital aphthous ulcerations, uveitis, skin lesions and other multisystem affections associated with vasculitis. Different types of vessels, predominantly veins, can be affected in BD. The frequency of vascular lesions in BD, such as superficial and deep venous thromboses, arterial aneurysms and occlusions, ranges between 7-29%. In this review, various factors of thrombogenesis in BD, particularly pro- and antithrombotic endothelial and non-endothelial factors, factors of coagulation, platelet activation and rheological changes are presented and discussed from positions of Virchow's triad of venous thrombosis. Despite advances in understanding of thrombogenesis in BD, still many issues of diagnosis and targeted preventive and therapeutic measures remain unresolved. Further studies are needed to clarify the pathobiology of BD-related thrombosis and to provide the clinicians with recommendations over the utility, safety and effectiveness of the antithrombotic therapy in BD.

Behçet’s Disease: an Insight from a Cardiologist’s Point of View

Behçet's disease (BD) is an enigmatic inflammatory disorder, with vasculitis (perivasculitis) underlying pathophysiology of its multisystemic affections. Venous pathology and thrombotic complications are hallmarks of BD. However, it has been increasingly recognized that cardiac involvement and arterial complications (aneurysms, pseudoaneurysms, rupture and thrombosis) are important part of the course of BD. Pericarditis, myocardial (diastolic and/or systolic dysfunction), valvular and coronary (thrombosis, aneurysms, rupture) involvement, intracardiac thrombi (predominantly right-sided) are, probably, the most frequent cardiac manifestations. Treatment of cardiovascular involvement in BD is largely empirical and aimed at suppression of vasculitis. The most challenging seems to be the treatment of arterial aneurysms and thromboses due to the associated risk of bleedings. Cardiologists should always bear in mind potential threats of (a)symptomatic cardiovascular involvement in BD.
