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

Surgical treatment of Behcet's disease with severe aortic regurgitation

Behcet's disease (BD) is a multisystem inflammatory disease that is characterized by oral aphthosis, genital aphthosis, ocular lesions, and cutaneous lesions. Although BD rarely affects the cardiovascular system, its symptoms can be shown as aortic regurgitation (AR), which requires surgical intervention. Due to the special pathogenesis of BD, a low preoperative diagnosis rate and a high incidence of serious complications, such as perivalvular leakage, valve detachment, and pseudoaneurysm after prosthetic valve replacement, surgical treatment of BD with severe AR has a poor prognosis. In recent years, new surgical strategies have been developed to improve treatment efficacy for this disease. This article reviews and summarizes the evolution of surgical techniques for BD with AR and aims to provide a reference for optimizing surgical strategies, improving perioperative management, and assisting prognosis in patients suffering from BD with severe AR.

Cardiovascular Sequelae and Genetics of Familial Mediterranean Fever: A Literature Review

INTRODUCTION

Familial Mediterranean fever (FMF) is an autoinflammatory fever syndrome distinguished by recurrent attacks of spontaneous peritonitis, pleuritis, fever, and arthritis. It is specifically seen in the ethnic groups of Mediterranean origin, but sporadic cases have been reported in Eastern Europe and America due to migrations. There is a number of cardiac manifestations associated with FMF.

METHODS

Using PubMed as the search engine, the literature search was done for articles published between 1958 and 2020. To summarize the body of available evidence, a scoping review was carried out to find relevant articles and case reports in patients of FMF with cardiovascular manifestations.

RESULTS

In the literature, there is a number of mechanisms explaining the cause of cardiac involvement in FMF, including the subclinical inflammation and secondary (AA) amyloid deposition in the vessels and the myocardium. There is a variable and often spurious course of these manifestations and it can be associated with a poor prognosis such as an acute myocardial infarction. In FMF patients, polyarteritis nodosa and Henoch-Schönlein purpura are seen more significantly as compared to the general population with increased frequency of mutations in Mediterranean fever (MEFV) gene. Through unclear mechanisms, Behçet's disease is associated with MEFV gene mutations and shares vascular manifestations with FMF. There is an interplay of IL-1 and MEFV gene, which impart an important role in inflammatory attacks of FMF. There is an intima-media thickening of blood vessels AA to persistent inflammation which can lead to atherosclerotic plaque formation resulting in atherosclerotic cardiovascular disease.

CONCLUSION

FMF and its associated cardiovascular diseases are interlinked to 2 main mechanisms: subclinical atherosclerosis and amyloid deposition, and colchicine is the primary treatment of patients with FMF which shows the regression of amyloid deposits and prevents cardiovascular sequelae.

Superior vena cava thrombosis and dilated cardiomyopathy as initial presentations of Behcet's disease

Background

Bechet’s disease (BD) is a relatively rare disease that causes recurrent oral and genital ulcers in addition to a variety of systemic manifestations. Concomitant superior-vena-cava (SVC) thrombosis and cardiac involvement with dilated cardiomyopathy (DCM) as initial presentations for BD is considered rare.

Case presentation

A 32-year-old-man presenting with intractable headaches and dyspnea. He was later diagnosed with SVC thrombosis and DCM. A diagnosis of BD was made after detailed history-taking.

Conclusions

Cardiovascular manifisations can be the initial presentation of BD. We aim to highlight the importance of early clinical recognition of BD as a cause of DCM and SVC thrombosis.

The Platelet-to-Lymphocyte Ratio as an Inflammatory Marker in Rheumatic Diseases

The platelet-to-lymphocyte ratio (PLR) has emerged as an informative marker revealing shifts in platelet and lymphocyte counts due to acute inflammatory and prothrombotic states. PLR has been extensively examined in neoplastic diseases accompanied by immune suppression and thrombosis, which can be predicted by combined blood cell counts and their ratios. Several large observational studies have demonstrated the value of shifts in PLR in evaluating the severity of systemic inflammation and predicting infections and other comorbidities, in inflammatory rheumatic diseases. The value of PLR as an inflammatory marker increases when its fluctuations are interpreted along with other complementary hematologic indices, particularly the neutrophil-to-lymphocyte ratio (NLR), which provides additional information about the disease activity, presence of neutrophilic inflammation, infectious complications, and severe organ damage in systemic lupus erythematosus. PLR and NLR have high predictive value in rheumatic diseases with predominantly neutrophilic inflammation (e.g., Behçet disease and familial Mediterranean fever). High PLR, along with elevated platelet count, is potentially useful in diagnosing some systemic vasculitides, particularly giant-cell arteritis. A few longitudinal studies on rheumatic diseases have demonstrated a decrease in PLR in response to anti-inflammatory therapies. The main limitations of PLR studies are preanalytical faults, inadequate standardization of laboratory measurements, and inappropriate subject selection. Nonetheless, accumulating evidence suggests that PLR can provide valuable information to clinicians who encounter multisystem manifestations of rheumatic diseases, which are reflected in shifts in platelet, lymphocyte, neutrophil, or monocyte counts. Interpretation of PLR combined with complementary hematologic indices is advisable to more accurately diagnose inflammatory rheumatic diseases and predict related comorbidities.

Genital ulcer severity score and genital health quality of life in Behçet's disease

Background

Behçet’s Disease (BD) is a chronic auto-inflammatory, multisystem relapsing/remitting disorder of unknown aetiology. Oro-genital ulceration is a key feature of the disease and has a major impact on the patients’ quality of life. Other clinical manifestations include ocular inflammation, rheumatologic and skin involvement, while CNS and vascular complications can lead to considerable morbidity. The availability of a valid monitoring tool for BD activity is crucial in evaluating the impact of the disease on daily life activity. The aims of this study were to validate a novel tool for monitoring genital ulceration severity in BD and to assess the impact of genital ulcers on the Genital Health Quality of Life (GHQoL).

Methods

Genital Ulcer Severity Score (GUSS) was developed using six genital ulcer characteristics: number, size, duration, ulcer-free period, pain and site. A total of 207 BD patients were examined, (137 females: mean age ± SD: 39.83 ± 13.42 and 70 males: mean age ± SD: 39.98 ± 11.95) from the multidisciplinary Behçet’s Centre of Excellence at Barts Health NHS Trust. GUSS was used in conjunction with Behçet’s Disease Current Activity Form (BDCAF).

Results

The over-all score of GUSS showed a strong correlation with all genital ulcer characteristics, and the strongest correlation was with the pain domain (r = 0.936; P < 0.0001). Ulcer average size and ulcer pain were the major predicting factors in GUSS (β = 0.284; β = 0.275) respectively, and P-values were significant. Multivariate regression analysis indicated that the ulcer pain, size and site are the main ulcer characteristics having an influence on the GHQoL (R²: 0.600; P < 0.0001).

Conclusions

This study established the practicality of GUSS as a severity monitoring tool for BD genital ulcers and validated its use in 207 patients. Genital ulcers of BD have a considerable impact on the patients GHQoL.

Left ventricular intracardiac thrombus in a patient with Behçet disease successfully treated with immunosuppressive agents without anticoagulation: a case report and review of the literature

Behçet disease (BD) is a chronic multisystem disorder with vasculitis underlying its systemic manifestations. Cardiac involvement and particularly left ventricular intracardiac thrombus are rarely diagnosed in the course of BD and are often associated with poor prognosis. The causes of intracardiac thrombi are unknown. It is plausible that specific proinflammatory pathways resulting in the endothelial cell injury and hypercoagulation contribute to the formation of thrombotic masses in the heart. Known thrombophilic factors such as methylenetetrahydrofolate reductase gene mutations, factor V Leiden mutation, proteins S and C, antithrombin III, activated protein C resistance, and antiphospholipid antibodies may contribute to the formation of intracardiac thrombi in BD. We report a case of a 24-year-old male patient with BD presented with left ventricular thrombus. Transthoracic echocardiography allowed to describe and monitor such a rare cardiac manifestation of the disease. A combination of high-dose corticosteroid and azathioprine successfully dissolved intracardiac thrombus within ten days without anticoagulation.

Cardiac complications of Behcet's disease

We describe two patients with Behcet's disease (BD) with cardiac complications and their response to treatment. This report adds to the evidence that cardiac involvement can be a feature of Behcet's disease and may be more common than previously thought.

Progression of coronary disease in a Behcet's patient in remission

Behcet's disease is characterised histologically by vasculitis. In the heart this can lead to aneurysm formation and thrombosis. There is also accelerated atherosclerosis, the mechanism of which is unclear. Patients with external disease from Behcet's disease are treated with immunosuppression. The authors present a case of aneurysmal disease in a Behcet's patient. This case demonstrates that coronary disease may progress in Behcet's patients despite external disease remission. Therefore, internal disease may progress in the absence of external symptoms when immunosuppressive therapy is usually stopped. This case raises the issue of whether immunosuppression should be continued in Behcet's patients with coronary disease to suppress disease progression or included in a treatment protocol for patients with Behcet's related coronary disease. Clinical trials on the use of immunosuppressive therapy for coronary disease in Behcet's patients are needed.

Vascular comorbidities in familial Mediterranean fever

Familial Mediterranean fever (FMF) is a common hereditary autoinflammatory disorder characterized by recurrent febrile attacks and polyserositis. The MEditerranean FeVer (MEFV) gene missense mutations altering the structure and function of pyrin protein play a significant role in the pathophysiology of the disease. Mutated pyrin is associated with the loss of delicate control of the inflammatory pathways, which results in a prolonged or augmented inflammation that predisposes these patients and carriers of the MEFV mutation to a pro-inflammatory state. This increased inflammation might lead to susceptibility to vascular comorbidities in FMF patients and even in carriers. In this review, we aim to discuss the vascular comorbidities seen in FMF patients. For this purpose, a thorough search was done in Web sites such as Pubmed, Web of Science, Scopus and Google Scholar, and the most relevant articles and case reports were evaluated. It seems that various vasculitides and the emerging problem of atherosclerosis have increasingly been recognized in these patients and, on the other hand, cardiac amyloidosis appears as a rare but devastating complication of FMF. Future studies will shed light on the unknown aspects of the emerging vascular problems in patients with FMF.
