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

Development and validation of a risk prediction model for valve regurgitation in Behçet's disease

BACKGROUND

In Behçet's disease (BD), mild-to-severe valvular regurgitation (VR) poses a serious complication that contributes significantly to heart failure and eventually death. The accurate prediction of VR is crucial in the early stages of BD subjects for improved prognosis. Accordingly, this study aimed to develop a nomogram that can detect VR early in the course of BD.

METHODS

One hundred seventy-two patients diagnosed with Behçet's disease (BD) were conducted to assess cardiac valve regurgitation as the primary outcome. The severity of regurgitation was classified as mild, moderate, or severe. The parameters related to the diagnostic criteria were used to develop model 1. The combination of stepAIC, best subset, and random forest approaches was employed to identify the independent predictors of VR and thus establish model 2 and create a nomogram for predicting the probability of VR in BD. Receiver operating characteristics (ROC) and decision curve analysis (DCA) were used to evaluate the model performance.

RESULTS

Thirty-four patients experienced mild-to-severe VR events. Model 2 was established using five variables, including arterial involvement, sex, age at hospitalization, mean arterial pressure, and skin lesions. In comparison with model 1 (0.635, 95% CI: 0.512-0.757), the ROC of model 2 (0.879, 95% CI: 0.793-0.966) was improved significantly. DCA suggested that model 2 was more feasible and clinically applicable than model 1.

CONCLUSION

A predictive model and a nomogram for predicting the VR of patients with Behçet's disease were developed. The good performance of this model can help us identify potential high-risk groups for heart failure. Key Points • In this study, the predictors of VR in BD were evaluated, and a risk prediction model was developed for the early prediction of the occurrence of VR in patients with BD. • The VR prediction model included the following indexes: arterial involvement, sex, age at hospitalization, mean arterial pressure, and skin lesions. • The risk model that we developed was better and more optimized than the models built with diagnostic criteria parameters, and visualizing and personalizing the model, a nomogram, provided clinicians with an easy and intuitive tool for practical prediction.

Giant coronary aneurysm of Behcet's disease with sudden syncope: a case report

Behcet's disease(BD) is a chronic inflammatory vasculitis that rarely affects the arteries, making myocardial infarction unlikely. We report a 28-year-old patient who was admitted to our hospital with multiple sudden syncope. Cardiovascular risk factors such as hypertension (HT), diabetes and obesity were not found in her. Preoperatively, imaging examinations suggested thrombosis of the inferior and superior vena cava and right heart combined with coronary artery aneurysm. The patient was finally diagnosed with a huge coronary artery aneurysm proximal to the left anterior descending artery. Syncope is considered to be caused right ventricular outflow tract obstruction. The patient received a successful aneurysm resection and had an uneventful postoperative recovery.

Pediatric Behçet's disease with cardiac valvular lesions: A case-based review

Due to the insidious nature of pediatric cardiac Behçet's disease (BD), misdiagnosis or missed diagnosis occurred frequently. We described a female pediatric patient with BD with cardiac valvular involvement diagnosed at the age of 4 years with clinical symptoms, including aphthous ulcers, fever, perianal ulcers, and erythema nodosum, as well as significantly elevated inflammatory markers. Echocardiography revealed that previously absent aortic valve lesions developed later and gradually worsened. After being diagnosed with BD with cardiovascular involvement, the patient was treated with glucocorticoids, immunosuppressants, biologics, diuretics, and aortic valvuloplasty. At the time of the follow up, the patient was stable. A review of 13 publications was conducted, including 14 cases of cardiac involvement in pediatric BD.

Surgical management of aortic regurgitation secondary to Behcet's disease

Background

Aortic regurgitation (AR) related to Behcet's disease (BD) is rare, but usually fatal. Perivalvular leakage (PVL) is high if AR related to BD treated with regular AVR. In this study, we report the surgical management of AR secondary to BD.

Methods

Between September 2017 and April 2022, 38 patients with AR secondary to Behcet's disease had surgery in our center. 17 patients did not have a BD diagnosis before surgery, 2 of them were diagnosed during surgery and received Bentall procedure. The remaining 15 patients received conventional AVR. 21 patients were diagnosed as BD before surgery, all of them received modified Bentall procedures. All patients were followed up by regular outpatient visits, transthoracic echocardiogram and CT angiography were performed to evaluate the aorta and aortic valve.

Results

Seventeen patients did not have a BD diagnosis at the time of surgery. Out of them, 15 patients received conventional AVR, and a total of 13 patients suffered PVL after surgery. Twenty-one patients had a BD diagnosis before surgery. They received modified Bentall procedures and IST and steroids were given both pre- and post-surgery. In this group treated with Bentall procedure no patient suffered PVL during follow up.

Conclusions

PVL is a complex scenario after conventional AVR for AR in BD. Modified Bentall procedure seems superior to isolated AVR in these cases. The use of IST and steroids before and after surgery in combination with modified Bentall procedure could have a role in effectively reducing PVL.

Behçet's Disease: A Radiological Review of Vascular and Parenchymal Pulmonary Involvement

Behcet's disease (BD) is a chronic systemic inflammatory disorder characterized by underlying chronic vasculitis of both large- and small-caliber vessels. Thoracic involvement in BD can occur with various types of manifestations, which can be detected with contrast-enhanced MSCT scanning. In addition, MR can be useful in diagnosis. Characteristic features are aneurysms of the pulmonary arteries that can cause severe hemoptysis and SVC thrombosis that manifests as SVC syndrome. Other manifestations are aortic and bronchial artery aneurysms, alveolar hemorrhage, pulmonary infarction, and rarely pleural effusion. Achieving the right diagnosis of these manifestations is important for setting the correct therapy and improving the patient's outcome.

Perioperative management with biologics on severe aortic valve regurgitation caused by Behçet syndrome: the experience from a single center

Background

To investigate the efficacy and safety of biologics in the perioperative management of severe aortic valve regurgitation (AR) caused by Behçet syndrome (BS).

Methods

We retrospectively analyzed 20 patients with severe AR caused by BS who were all treated with biologics during the perioperative period of cardiac surgeries in our center between February 2016 and October 2020.

Results

A total of 20 patients with severe AR were enrolled, including 19 males and 1 female, with a mean age of 39.1 ± 8.8 years and a median course of 8 [interquartile range (IQR) 5.25-10.00] years. Before biologic administration, 92.9% of the patients who underwent aortic valve replacement had failed conventional therapy and developed postoperative paravalvular leakage (PVL) at a median interval of 4 months. Biologics were administered with background glucocorticoids (GCs) and immunosuppressants during the perioperative period for 22 aortic valve surgeries, including preoperatively with a median interval of 3.5 (IQR 2.75-4.25) months in 13 cases and within 3 months postoperatively in 9 cases. After a median follow up of 21 (IQR 15-32) months, 2 out of 13 cases (15.4%) preoperatively, and 1 out of 9 cases (11.1%) postoperatively treated with biologics developed PVL, and the rest were event free. The Behçet's Disease Current Activity Form score improved significantly (7 versus 0, median, p < 0.0001). Decrease of erythrocyte sedimentation rate [25.0 (IQR 11.00-36.25) mm/h versus 6.5 (IQR 4.0-8.8) mm/h, p < 0.001], and C-reactive protein [20.77 (IQR 7.19-29.58) mg/l versus 1.53 (IQR 0.94-2.92) mg/l, p = 0.001] were achieved rapidly and effectively. The GC dosage tapered from 40 (IQR 30-60) mg/d to 10 (IQR 5-11.25) mg/d, p < 0.0001. Immunosuppressants were tapered in number and dosage in 6 (30%) and 20 patients (100%), respectively. No serious adverse event was observed.

Conclusion

Our study suggests that biologics were effective and well tolerated for the perioperative management of severe and refractory AR caused by BS, which significantly reduced the occurrence of postoperative PVL and had favorable GC- and immunosuppressant-sparing effect.

Prognostic analysis of Behçet's disease with aortic regurgitation or involvement

Background

Aortic regurgitation is the most common cardiovascular damage in Chinese patients with Behçet’s disease (BD) and is usually associated with aortic disease. These patients are easily misdiagnosed, and their prognosis is poor, even after surgical treatment. This study aimed to analyse potential factors that can improve the prognosis of BD patients with aortic regurgitation and/or aortic involvement.

Methods

Twenty-two patients with diagnosed or suspected BD as well as aortic regurgitation and/or aortic involvement in our hospital from 2012 through 2017 were collected in this study. Their clinical characteristics were listed, and the diagnosis of BD was evaluated by two different criteria sets. The influences of surgical treatment and immunosuppressive therapy (IST) on their prognosis were also explored.

Results

The diagnostic positive rate of the International Criteria for Behçet’s Disease was higher than that of the International Study Group criteria (kappa value 0.31, p < 0.05), indicating that the diagnostic consistency between the criteria sets was poor. There was no significant difference in survival between patients who had undergone ≤ 1 operation and those with ≥ 2 operations. Aortic valve replacement alone or in combination with aortic root replacement had no significant effect on the incidence of reoperation or death, but IST did significantly reduce this incidence (p < 0.05). However, there was no significant difference in the occurrence of reoperation or death between preoperative and postoperative IST versus postoperative IST only.

Conclusion

IST significantly improved the prognosis of BD patients with aortic regurgitation and/or aortic involvement.

Getting to the <em>heart</em> of the matter: diagnostic tools and therapeutic approach to cardiac involvement in Behçet syndrome A Tunisian case series

The aim was to investigate the frequency and spectrum of cardiac involvement (CI) in patients with Behçet syndrome (BS) in the Tunisian context, and to assess the clinical and imaging features, treatment, and outcomes. We retrospectively retrieved the medical records of patients with CI among 220 BS patients admitted to the hospital internal medicine department between February 2006 and April 2019, who fulfilled the International Study Group diagnostic criteria for BS. Ten patients (8 men, 2 women) were eligible for the study. Mean age was 37.3 years. Three patients had 2 isolated episodes of cardiac BS. The different types of CI were coronary artery disease (5/10), intracardiac thrombus (4/10), pericarditis (1/10), myocarditis (1/10), and myocardial fibrosis (1/10). Five patients had associated vascular involvement (50%). Medical treatment was based on corticosteroids and colchicine in all patients (100%), anticoagulants in 8 (80%), and cyclophosphamide followed by azathioprine in 9 (90%). The clinical course was favorable in 9 patients; 1 patient died. CI remains an important feature of BS because of its association with increased risk of mortality and morbidity. Therefore, early screening and detection with imaging methods are paramount. Also, better cooperation between rheumatologists and cardiologists could improve outcomes.

A coronary artery aneurysm revealing a Behçet's disease: a case report

Behçet’s disease (BD) is a multisystemic chronic vasculitis characterized by its clinical polymorphism. It concerns mainly young men and generally appears between the third and the fourth decades. Cardiac involvement in Behçet’s disease is rare but represents a major prognostic factor. We report the case of a young man admitted in our department for the management of an acute coronary syndrome revealing a Behçet’s disease. Coronary angiography had shown a giant thrombosed aneurysm of the left coronary artery. Surgical treatment was successfully performed and the patient had a left anterior descending coronary artery bypass using the left internal mammary artery graft.

When Behcet's disease meets Stanford type A aortic dissection, heart transplantation is a reliable treatment

Behcet's disease (BD) is an immune system disease characterized by multi-system vascular inflammation. Its occurrence in patients who experience a Stanford type A aortic dissection (AD) is very rare, but extremely dangerous. A 44-year-old male patient was diagnosed with an acute Stanford type A AD and underwent a standard Bentall procedure and total aortic arch replacement plus descending aortic stented elephant trunk implantation. Aortic valve leakage and an aortic root pseudoaneurysm developed 3 months after surgery. At this time, we suspected that this patient had BD. After immunosuppressive treatment, we performed modified Bentall again; however, the heart failure occurred shortly after the second operation. Finally, we successfully treated this patient with a heart transplant. This is the first report of a heart transplant to treat BD with acute Stanford type A AD. In the diagnosis and treatment of acute Stanford type A AD, in addition to the traditional pathogenic factors, we need to be alert to BD, and heart transplantation may be a good way to treat such patients.

Evaluation of the relationship between Behcet's disease and cardiovascular disorders through metabolic function and copeptin

Introduction

Behcet's disease (BD) is a chronic inflammatory and multisystem vasculitis. Cardiac involvement is one of the major complications of BD. Cardiac involvement is sporadic in terms of its specific relationship to mortality. How to identify and follow up on cardiac-related complications in BD patients has yet to be determined.

Aim

The aim of our study is to assess cardiovascular diseases in BD patients by measuring metabolic function and copeptin levels and comparing these to a healthy control group. Knowing the specific metabolic functions that are negatively affected by BD will help doctors determine which functions need to be more closely monitored in BD patients. Our study is the first study in the available literature that evaluates copeptin in BD patients.

Material and methods

A control group of 58 healthy volunteers, including 32 females and 26 males (average age: 39.8 ±10.3 years, range: 18-50 years), was formed to compare with 84 BD patients (average age: 40.5 ±11 years, range: 21-63 years), including 39 females and 45 males. Diastolic and systolic blood pressure, height, weight, body mass index (BMI), and waistline were measured for both groups. All study patients were also given hemograms, and fasting blood sugar (FBS), uric acid, lipid profile, insulin, C-reactive protein (CRP), and copeptin levels were measured. An ELISA Kit was used to measure copeptin.

Results

FBS, CRP, and insulin levels were significantly higher in the patient group (p < 0.001, p = 0.004, and p = 0.038, respectively). Patients who had had the disease for more than 10 years had higher BMIs, total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride (TG) levels (p = 0.034, p = 0.004, p = 0.016, and p = 0.045, respectively). Additionally, CRP levels were found to be higher in long-term patients and patients with active lesions. Diastolic blood pressure and waist circumference were also higher in the BD group. Patients who had active lesions had significantly higher diastolic blood pressure (p = 0.047). There were no statistically significant differences in copeptin levels between BD and control groups.

Conclusions

Cardiovascular involvement rarely contributes to the high mortality rate of BD patients. There were meaningful elevations in metabolic markers identified when BD and cardiovascular disease risk was assessed with metabolic parameters. The cardiac disease risk should be closely followed using metabolic functions, particularly in long-term BD patients with vascular involvement.
