What Is Vascular Behçet's Disease?

Thrombosis in vasculitis: An updated review of etiology, pathophysiology, and treatment

Introduction

Thromboembolic disease is a complication of many vasculitides. A common observation is that thromboembolic events coincide with the period of vasculitic disease, but the mechanism by which this occurs remains unclear. Inflammatory thrombosis is now recognized as a symptom of arteritis rheumatic, and vasculitides such as Behçet's syndrome (BS), and anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) or giant cell arteritis (GCA). This systematic review aimed to explain recent findings related to etiology, pathophysiology, and treatment methods for BS, AAV, and medium/large-vessel vasculitis.

Methods

A comprehensive literature search on English sources from PubMed, Scopus, MEDLINE, Science Direct, ProQuest, AIM, CINAHIL, and ELDIS databases was used to find the relevant articles and reports. The relevant papers (having full text) were obtained until June 2023. Two independent reviewers screened the titles and abstracts of the obtained articles, and a third arbitrator resolved disputes between the reviewers.

Results and conclusion

It is becoming increasingly clear that certain systemic inflammatory diseases, like vasculitis, are linked to a higher risk of both venous and arterial thrombosis. An increased incidence of thromboembolic disease in AAV has been noted, particularly during times of active disease. Growing evidence supports the use of immunosuppression in the management of venous thrombosis in vasculitis. These patients also have a higher risk of developing ischemic disease.

Behçet's disease detecting by hemoptysis and recurrent epididymo-orchitis: A case report from Syria

Behçet's disease is a chronic systemic inflammatory vasculitis of unknown etiology. It is characterized by recurrent episodes of oral aphthous ulcers, genital ulcers, skin lesions, ocular lesions, and other manifestations. This disease affects many organs and systems, showing a wide range of clinical features. Although pulmonary artery involvement is not common in Behçet's disease, its presence carries a substantial risk of mortality. This report provides a detailed history of a 25-year-old male who was admitted with productive cough, hemoptysis, dyspnea on minimal exertion, fever, and chest pain. He had recurrent orchitis and epididymitis for 7 years, as well as oral and genital ulcers and severe headache. Clinical examination revealed decreased breath sounds at the right middle lung. Thoracic computed tomography angiography confirmed multiple pulmonary artery aneurysms bilaterally. The patient was diagnosed with Behçet's disease, and immunosuppression therapy was initiated. During follow-up, the patient did not report any complications. This case report underscores the significance for clinicians to consider Behçet's disease as a differential diagnosis in patients presenting with hemoptysis and a history of orchitis and epididymitis, given that Behçet's disease rarely causes pulmonary artery aneurysms.

Endovascular Treatment of the Ruptured Pseudoaneurysm of Common Femoral Artery in Behcet's Disease: Report of a Case with Four Years of Follow-Up

Behcet's disease (BD) is a vasculitic condition that affects arteries and veins of all sizes. Arterial pseudoaneurysm is a rare but life-threatening complication of BD. We reported a 41-year-old man with 20 years history of BD and 5 years history of bilateral blindness. The patient presented with sudden onset of pain and swelling in his left groin and was diagnosed with the ruptured pseudoaneurysm of the left common femoral artery (CFA), which extended into the origins of superficial and deep femoral arteries. The patient was in the active phase of BD; therefore, he was initially treated with corticosteroids and cyclophosphamide pulse therapies and subsequently underwent stent graft placement. Post stenting angiography and postprocedural ultrasonography confirmed the successful exclusion of pseudoaneurysm without any evident complication. Four years of follow-up was uneventful.

Vascular Behcet's Disease Preceded by Fever of Unknown Origin: Usefulness of Ultrasonography for the Detection of Large-Vessel Vasculitis

Behcet's disease is a systemic vasculitis characterized by oral and genital ulcers, erythema nodosum, and ocular involvement. Fever of unknown origin is a relatively rare event in Behcet's disease. We present the case of a 17-year-old male patient who suffered from prolonged fever for two months. The patient tested positive for HLA-B52 and levels of acute phase reactants were elevated. He complained of sore throat and neck pain that were evaluated by cervical ultrasonography, which revealed thickening of the carotid arterial wall and narrowing of the vessel lumen. The patient was diagnosed with vascular Behcet's disease and treated with glucocorticoid, which improved the clinical symptoms and thickening of the carotid arterial wall as detected by color duplex ultrasonography. Since vascular Behcet's disease may lead to morbidity and mortality, we suggest the early use of ultrasonography to help detect medium/large-vessel vasculitis. Prolonged fever in patients with Behcet's disease should be promptly evaluated for vascular involvement.

Evaluation of diagnostic performance of haematological parameters in Behçet's disease

OBJECTIVE

Behçet's Disease (BD) is a polygenic and chronic autoinflammatory multisystemic vasculitis disease characterised by mucocutaneous, musculoskeletal, neurological, gastrointestinal and ophthalmologic lesions. There has been no specific test or serum marker to measure and determine the diagnosis and severity of BD.

PURPOSE

The study aimed to investigate the diagnostic performance of haematological parameters as MLR (monocyte to lymphocyte ratio), NLR (neutrophil to lymphocyte ratio), PLR (platelet to lymphocyte ratio), MPV (mean platelet volume), MPVPR (mean platelet volume to platelet ratio), LMR (lymphocyte to monocyte ratio), LPM (lymphocyte and platelet multiplication), WLP (lymphocyte and leukocyte multiplication), RDW (red blood cell distribution width) and PCT (plateletcrit) in BD and compare these with disease activity and clinical findings.

METHODS

A total of 266 participants (49 healthy control and 217 BD patients) were recruited from the rheumatology department in a single-centre as a case-control study. The laboratory data were obtained from the electronic registration database. BD Activity scores (BDCAF/Behcet's Disease Current Activity Form) were calculated. Laboratory findings of BD patients and healthy controls were compared and evaluated.

RESULTS

RDW, Platelet, PCT, NLR and PLR values were significantly higher in patient group than in the healthy controls. However, haemoglobin, MPVPR and LMR were significantly lower in the patient group which compared with the healthy controls. LPM in BD with genital ulcers, WLP in BD with genital ulcers and arthritis, MPR in BD with uveitis, RDW in BD with thrombosis and neuro-Behçet's disease (NBD), PLR in NBD were observed to be higher. However, LMR in NBD and MPV in BD with thrombosis were lower than those without. There was a positive correlation between BDCAF score and RDW, and NLR.

CONCLUSION

Haemoglobin, RDW, Platelet, PCT, NLR, LMR, PLR and MPVPR were statistically significant predictors for BD. RDW, PCT and NLR are the most valuable predictors for BD.

Usefulness of duplex ultrasonography to detect collagen sponge misplacement into the arterial lumen during the use of Angio-Seal: A case report

A 76-year-old man who had undergone percutaneous coronary intervention suffered intermittent claudication. Duplex ultrasonography revealed superficial femoral artery stenosis with an intraluminal heterogeneous echogenic mass. We suspected that stenosis was caused by the puncture procedure of the Angio-Seal. Open surgery revealed that a collagen sponge that should have been outside the arterial wall was misplaced in the wall with massive granulation, and atherectomy with patchplasty was performed. Vessel deterioration was considered due to several factors, including inappropriate access site, arterial wall calcification, and comorbidities like Behçet's disease. Ultrasonography is a convenient and useful method to evaluate arterial lesions.

Colchicine therapy for deep vein thrombosis in a patient with vascular-type Behçet disease: A case report

RATIONALE

Behçet Disease (BD) is a chronic inflammatory vasculitis with thrombogenicity and multisystem involvement. Deep vein thrombosis (DVT) in the lower extremities is the most frequent manifestation of vascular involvement in BD. The causes of thrombosis vary widely and include congenital predisposition and acquired factors, but of all the thrombosis, the cause is rarely BD. Furthermore, there are few reports of treatment for thrombosis in BD.

PATIENT CONCERNS

We herein describe the case of an Asian male patient aged 40 years, admitted to our hospital for left leg pain, edema, and swelling.

DIAGNOSES

We confirmed the DVT and pulmonary artery thrombosis (PAT) by contrast computed tomography angiogram. At the same time, the patient developed oral ulcerations and skin lesions consistent with BD.

INTERVENTIONS

The patient was initially treated with anticoagulants. However, because the improvement of DVT was inadequate, we added colchicine in anticipation of anti-inflammatory effects. After that, anticoagulation was discontinued, and only colchicine was continuously prescribed.

OUTCOMES

We observed an almost complete resolution of DVT and PAT with no recurrence of thrombosis for 6 months after discharge.

LESSONS

This case shows us that we should consider BD as a differential diagnosis of DVT and that colchicine therapy is effective for inflammation-induced thrombosis in BD.

Vasculo-Behçet disease complicated by conversion disorder diagnosed with 18F-fluoro-deoxy-glucose positron emission tomography combined with computed tomography (PET/CT)

Vasculitis in Behçet's disease, termed "vasculo-Behçet's disease," is a major cause of mortality and morbidity. We report a case of vasculo-Behçet's disease complicated by conversion disorder, in which ¹⁸F-fluoro-deoxy-glucose positron emission tomography combined with computed tomography (FDG PET/CT) was useful for the diagnosis. A twenty-two-year-old woman recently diagnosed with tonsillitis presented with fever, right foot pain, left equinovarus foot, and numbness in both hands and feet. Laboratory data showed elevated levels of c-reactive protein (CRP). The patient was positive for HLA B51; pathergy testing was also positive. Nerve conduction velocity and electromyography were normal. MRI showed swelling of the left crural muscle group. PET/CT showed intense FDG uptake in the left popliteal artery, demonstrating active vasculitis. The patient was diagnosed with vasculo-Behçet's disease and treated with corticosteroids, colchicine, and infliximab, which led to obvious improvement of the MRI findings and reduction in CRP. However, left equinovarus foot and numbness in the extremities persisted. She also developed aphonia. They were attributed to psychogenic dystonia and conversion disorder, and psychiatric treatment was effective in relieving those symptoms. We suggest that PET/CT may be useful for the early diagnosis of medium-sized vessel vasculitis in patients with Behçet's disease.
