Coronary involvement in patients with Behçet’s disease

The severity of coronary heart disease and the incidence of later diabetic retinopathy in diabetic population: A retrospective cohort study

OBJECTIVES

The coronary heart disease (CHD) can influence the development of several diseases. The presence of CHD is correlated to a higher incidence of concurrent diabetic retinopathy (DR) in previous study. Herein, we aim to analyze the relationship between the CHD severity and following DR with different severity.

METHODS

A retrospective cohort study was conducted with the usage of Taiwan National Health Insurance Research Database (NHIRD). The CHD patients with DM were categorized into those with medical treatments and those received percutaneous coronary intervention (PCI) management with a 1:1 ratio. The major outcome was the development of DR, diabetic macular edema (DME) and proliferative diabetic retinopathy (PDR) 6 months after the onset of CHD.

RESULTS

There was 7317, 316, and 386 episodes of DR, DME and PDR in the mild CHD groups and 8568, 411, and 508 events of DR, DME and PDR in the severe CHD groups, respectively. The severe CHD group showed a significantly higher incidence of DR (aHR: 1.063, 95% CI: 1.038-1.089, P = 0.0324), DME (aHR: 1.412, 95% CI: 1.252-1.594, P = 0.0092) and PDR (aHR: 1.314, 95% CI: 1.172-1.473, P = 0.0113) compared to the mild CHD group. The cumulative incidence of DR was significantly higher in the severe CHD group (P < 0.001). In the subgroup analysis, the association between CHD severity and DR was more prominent in the female population (P = 0.0224).

CONCLUSIONS

The severe CHD is associated with higher incidence of following DR, DME and PDR, while the incidence of DR in CHD is positively correlated to longer disease period.

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.

Recurrent left main stem stenosis in a young female with Behçet's aortitis: a case report

Background

Behçet's disease (BD) is a rare and complex vasculitis disorder renowned for its diverse clinical presentations. Cardiovascular involvement is reported to be present in 7-46% of the patients, with coronary arteries being involved in only 0.5%. The management of cardiovascular complications can be challenging due to the rarity of such cases and the absence of standardized guidelines regarding diagnosis and treatment.

Case summary

We report the case of a 27-year-old patient with BD with known aortitis and pulmonary arteritis, who presented with recurrent acute coronary syndromes related to critical left main coronary artery stenosis. She was initially managed with percutaneous coronary interventions twice. Following recurrent stent failure, she eventually underwent urgent coronary artery bypass surgery, together with aortic valve replacement and aortic root repair. She made an uneventful recovery and remains well 6 months following her operation.

Discussion

This case illustrates the significant challenges that can be encountered when managing coronary complications in patients with BD. Both percutaneous and surgical options have been reported in the literature with variable outcomes. Multi-disciplinary team involvement is of utmost importance in order to offer a balanced therapeutic strategy to these patients. Further research is required to shed light to the unknowns surrounding this rare cohort.

The Degrees of Coronary Heart Disease and the Degrees of New-Onset Blepharitis: A Nationwide Cohort Study

In this study, we aimed to evaluate the association between the severity of coronary heart disease (CHD) and the subsequent severity of blepharitis. This retrospective population-based cohort study was conducted using the National Health Insurance Research Database (NHIRD) of Taiwan. The participants with a CHD diagnosis were divided into mild CHD and severe CHD groups at a 1:2 ratio, according to whether percutaneous coronary intervention (PCI) was performed. The main outcomes were the development of blepharitis and severe blepharitis with the application of antibiotics. Cox proportional hazard regression was performed to obtain the adjusted hazard ratio (aHR) for blepharitis, with a 95% confidence interval (CI) between the groups. There were 22,161 and 15,369 blepharitis events plus 9597 and 4500 severe blepharitis episodes in the mild and severe CHD groups, respectively. The severe CHD group showed a significantly higher incidence of blepharitis development (aHR, 1.275; 95% CI: 1.051-1.912, p = 0.0285), whereas the incidence of severe blepharitis was not significantly different between the groups (aHR, 0.981; 95% CI: 0.945-1.020, p = 0.3453). The cumulative probability of blepharitis was significantly higher in the severe CHD group than in the mild CHD group (p < 0.001). In the subgroup analyses, the correlation between severe CHD and blepharitis was more significant in patients older than 70 years compared to the younger group (p = 0.0115). In conclusion, severe CHD is associated with a higher incidence of blepharitis than mild CHD, and this correlation is more prominent in individuals older than 70 years.

Imaging characteristics and prognostic factors of Behcet's disease with arterial involvement: A long-term follow-up study

PURPOSE

To investigate the imaging characteristics and prognostic factors for the long-term survival of Behcet's disease (BD) with arterial involvement.

METHODS

In this retrospective study, BD patients with arterial involvement were identified from January 2003 to January 2020. Arterial lesions were detected by ultrasonography, traditional arteriography, and/or computed tomography angiography (CTA). Cox proportional hazards regression analyses were performed to identify the prognostic factors.

RESULTS

Totally, 84 BD patients with arterial involvement were identified (73.8 % males). The mean age at BD diagnosis was 39.1 ± 13.1 years. Arterial involvement was the initial manifestation in 33.3 % of the patients, and the median time from BD diagnosis to arterial involvement was 6 (IQR 1-15.5) years for the rest of patients. Systemic artery involvement and pulmonary artery involvement (PAI) were found in 64 and 27 patients, respectively. Approximately 94.0 % (79/84) of the patients had more than one artery involved concurrently or successively during the course of BD. Aneurysm/dilation was the most prevalent lesion in the aorta (76.0 %), while stenosis/occlusion was the main lesion of the coronary artery (90.9 %) and other aortic branches (74.5 %). Pulmonary hypertension was found in 70.4 % (19/27) of patients with PAI. The 5- and 10-year survival rates of BD patients with arterial involvement were 87.4 % and 84.1 %, respectively. Cardiac involvement (HR: 4.34) and pulmonary artery aneurysm/dilation (HR: 4.89) were independently associated with mortality.

CONCLUSIONS

Arterial lesions associated with BD usually involve multiple arteries and manifest differently in different types of arteries. Cardiac involvement and pulmonary artery aneurysm/dilation are independent prognostic factors of BD patients with arterial involvement.

A case of Behçet syndrome presenting with acute coronary syndrome

Cardiac involvement (CI) is rare in Behçet syndrome (BS), but the important point is that CI may be the first manifestation of the disease. The presence of CI worsens the prognosis of BS, so early diagnosis and early initiation of immunosuppressive treatment (IST) are vital. Coronary aneurysm may develop spontaneously in these patients, or any vascular intervention may cause aneurysm with a pathergy-like reaction. The risk of restenosis is high after percutaneous coronary intervention or coronary artery bypass surgery applied without IST. Therefore, it should be kept in mind that IST constitutes the main step of treatment. Herein, we present a young male diagnosed with BS after acute coronary syndrome caused by coronary artery aneurysms and thrombosis.

Vascular Involvement in Behcet's Disease: An Evaluation of 147 Cases and Literature Review

Objectives

Behcet's disease (BD) is characterized by systemic vasculitis with inflammation that can affect various body organs. In BD, vasculitis primarily manifests with venous involvement, distinguishing it from other forms of systemic vasculitis.

Methods

We retrospectively analyzed the demographic and clinical characteristics of 147 patients diagnosed with vascular BD in our center.

Results

Vascular BD cases accounted for 25.0% (147 out of 589) of all BD patients. A statistically significant correlation was found between gender and vascular involvement that was seen predominantly in males (76.9%). In 71 patients, a vascular event developed during follow-up for BD, while in 76 patients the disease was diagnosed after the occurrence of a vascular event (51.7%). The most common vascular event was deep vein thrombosis in the lower extremities (69.4%). Arterial involvement was primarily observed in the pulmonary arteries (12.9%). Patients with lower extremity deep vein thrombosis tended to be younger, while those with pulmonary artery involvement were typically older. Overall, veins were affected 4.5 times more frequently than arteries.

Conclusion

The prevalent type of venous involvement was deep vein thrombosis in the lower extremities. Thrombotic events in BD cannot be solely attributed to abnormalities in thrombotic factors. The treatment of thrombotic events in BD remains contentious, with anticoagulant efficacy being debated and immunosuppressive therapy representing the primary treatment approach. Behcet's disease should be considered when a young male patient presents with an arterial or venous vascular event, especially if it is recurrent.

Cardiovascular risk in vasculitis

The present review summarizes the burden, risk factors, biomarkers of and therapeutic consideration for cardiovascular disease in systemic vasculitis. Ischemic heart disease (IHD) and stroke are intrinsic features of Kawasaki disease, Takayasu arteritis, Giant Cell Arteritis (GCA), and Behcet's disease. The risk of IHD and stroke is increased in anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) and cryoglobulinemic vasculitis. Behcet's disease could present with venous thromboembolism. The risk of venous thromboembolism is increased in AAV, polyarteritis nodosa, and GCA. The risk of cardiovascular events is greatest at or immediately after the diagnosis of AAV or GCA, therefore, controlling vasculitis disease activity is of utmost importance. Traditional as well as disease-related risk factors drive the heightened cardiovascular risk in vasculitis. Aspirin or statins reduce the risk of IHD or stroke in GCA or the risk of IHD in Kawasaki Disease. Venous thromboembolism in Behcet's disease should be treated with immunosuppressive therapy rather than with anticoagulation.

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.

Cardiac magnetic resonance imaging in patients with Behçet's disease

BACKGROUND

Behçet's disease (BD) is a multisystemic vasculitis that may affect the heart. However, the incidence and nature of cardiac involvement in BD have not been clearly documented yet. The aim of this study was to delineate the cardiac magnetic resonance imaging (MRI) appearances of cardiac involvement in BD patients.

METHODS

This cross-sectional observational study was carried out 30 BD patients without known cardiac disease. Patients were subjected to history taking, physical examination, echocardiography and cardiac MRI.

RESULTS

At least one abnormality on cardiac MRI was observed in 20/30 patients (66.67%). Myocardial oedema was observed in 3 patients (10%) and late gadolinium enhancement in 1 patient (3.3%). Pericardial effusion was found in 3 patients (10.0%), global hypokinesia in 6 patients (20.0%) and intra-cardiac thrombosis in only 1 patient (3.3%). Pulmonary artery was dilated in 4 patients (13.3%). Left ventricular (LV) and right ventricular (RV) end diastolic volume were altered in 4 patients (13.3%) and 7 patients (23.3%) respectively. LV and RV end systolic volume were abnormal in 7 patients (23.3%) and 5 patients (16.7%) respectively. There was aortic valve regurge in 2 patients (6.7%), tricuspid valve regurge in 9 patients (30%), and mitral valve regurge in 9 patients (30%). Dilated left main coronary artery was found in 2 patients (6.7%) and arrhythmogenic right ventricular dysplasia in only one patient 1 patient (3.3%). On logistic regression analysis, BD activity index score was a significant predictor of cardiac abnormalities.

CONCLUSION

BD may cause cardiac abnormalities without clinical manifestations and cardiac MRI may represent a tool for early detection of these subtle abnormalities. Higher BD activity index scores are strongly linked to cardiac problems.

Myocardial involvement in Behçet's disease may be higher in patients with Neuro-Behçet's disease: a speckle tracking echocardiographic study

BACKGROUND

Behcet's disease (BD) may present with life threating complications including neurological and cardiovascular involvement. Neuro-Behcet's disease (NBD) is one of the most important causes of morbidity and mortality in patients with BD. The aim of the present study is to investigate whether patients with NBD are different than BD patients with other manifestations in terms of subclinical myocardial dysfunction.

METHODS

Forty patients with NBD (23 female, mean age: 42.4 ± 9.4 years), 40 patients with BD (9 female, mean age: 39.7 ± 9.0 years) and 40 controls (20 male, mean age: 41.8 ± 6.5 years) were consecutively included in the study. All subjects underwent a transthoracic echocardiography for evaluation of left ventricular (LV) and atrial (LA) functions with two-dimensional (2D) speckle tracking echocardiography (STE).

RESULTS

Baseline characteristics, clinical data, LV dimensions, systolic and diastolic functions were all in normal range among the groups. LV global longitudinal strain (LV-GLS) was significantly lower in patients with NBD and BD patients without neurologic involvement compared to controls. LA conduit strain was significantly lower in patients with NBD compared to controls. Patients with both parenchymal NBD and vascular NBD manifestations had significantly lower LV-GLS and LA conduit strain compared to controls. Linear regression analysis demonstrated that among cardiovascular risk factors only presence of NBD was the independent predictor of LV-GLS.

CONCLUSIONS

BD is associated with impaired LV and LA functions. LV-GLS and LA conduit strains of the patients with NBD were lower. NBD was an independent predictor of LV-GLS, suggesting a link between neurological manifestations and cardiac dysfunction in BD patients.

Patients characteristics in Behçet's Syndrome and their associations with major organ involvement: a single-centre experience of 2118 cases

Objectives: To evaluate the demographic and clinical characteristics of patients with Behçet's syndrome (BS), and to define their associations with the presence of major organ involvement (MOI).Method: Medical records of 2118 patients (964 males, 1154 females) were analysed retrospectively. MOI was defined as the presence of at least one of vascular, eye, nervous, or gastrointestinal system involvement. Univariable and multivariable binary and ordinal logistic regression analyses were applied to assess the factors that were potentially associated with MOI.Results: The mean ± sd age at diagnosis was 30.5 ± 9.4 years. Genital ulcer and joint involvement were more common in females (both p < 0.001), while MOI was more frequent in males (p < 0.001). Genital ulcer (p < 0.001) and vascular involvement (p = 0.006) were more common in patients with a younger age at diagnosis, while joint involvement was more common in older patients. A total of 1097 patients (51.8%) had at least one MOI, 322 (15.2%) at least two MOIs, and 48 (2.3%) at least three MOIs. Male gender, smoking history, and absence of genital ulcer were significantly associated with MOI in multivariable binary logistic regression. Multivariable ordinal regression analyses confirmed the association between MOI and male gender and smoking, but not the protective effect of genital ulcers. In both regression analyses, we found no significant effects of age, human leucocyte antigen-B51, skin involvement, or joint involvement on MOI.Conclusion: Male gender and positive smoking history have a significant influence on the presence of MOI in patients with BS.

Behçet's Syndrome Apart From the Triple Symptom Complex: Vascular, Neurologic, Gastrointestinal, and Musculoskeletal Manifestations. A Mini Review

Behçet‘s Syndrome (BS) is a variable vessel vasculitis according to the Chapel Hill Consensus Nomenclature (1) and may thus affect any organ, including major and minor arterial and venous vessels to a varying degree and with varying frequency. Although the main features of BS are recurrent oral and genital aphthous ulcers, cutaneous lesions, ocular inflammation and arthritis—major vessel and life—or organ threatening involvement of internal organs and the central and peripheral nervous system occur. In general, BS in Europe appears to form six phenotypes of clinical manifestations (2), which are (1) mucocutaneous only, (2) predominant arthritis/articular involvement, (3) vascular phenotype, (4) ocular manifestations, which are most likely associated with CNS manifestations and HLA-B51, (5) dominant parenchymal CNS manifestations (being associated with the ocular ones), and (6) gastrointestinal involvement. Mucocutaneous manifestations are present in almost all patients/all phenotypes. In the following review, we summarize the current knowledge concerning vascular, neurologic, gastrointestinal and musculoskeletal manifestations of the disease.

Distinct clinical characteristics of pediatric Behçet's syndrome: A study from a referral center in China

OBJECTIVES

To describe the clinical features and patterns of phenotype aggregation in pediatric Behçet's syndrome (BS) in a tertiary center in China.

METHODS

This was a cross-sectional study of consecutive BS patients in Huadong Hospital, Fudan University between September 2012 and January 2020. Pediatric BS was defined as diagnosed before 16 years old. We compared clinical variables between pediatric and adult patients. We calculate relative risks (RRs) of clinical variables according to sex. Moreover, a hierarchical cluster analysis was undertaken according to 29 clinical variables to determine homogeneous subgroups.

RESULTS

From 1596 consecutive BS cases, we identified 69 pediatric BS. Compared with adult-diagnosed BS, pediatric-diagnosed patients had a higher frequency of folliculitis [RR 1.57 (95% CI 1.12, 2.20)], a lower frequency of arthralgia [RR 0.15 (95% CI 0.02, 1.07)] and panuveitis [RR 0.43 (95% CI 0.18, 1.03)], no cardiac lesion. There was an association between male and arterial thrombosis or aneurysms (p = .006). A cluster analysis stratified three sub-clusters (C1-C3): C1 (n = 30) showed a disease type merely affecting skin and mucosa. C2 (n = 20) represented the gastrointestinal type; most patients presented with intestinal involvement, and two cases with esophageal ulcers. In C3 (n = 19), showing a mixture of uveitis, vascular and central nervous system (CNS) involvement, six patients presented with uveitis and nine had vascular lesions, and three cases had CNS lesions.

CONCLUSION

We conducted a comprehensive statistical analysis in a cohort of pediatric patients with BS in China. Less ocular involvement and no cardiac lesions were observed in childhood-diagnosed patients. For the first time, three distinct phenotype subgroups in pediatric-diagnosed patients were identified by cluster analysis.Key messagesThis study demonstrated the phenotype discrepancy between childhood and adult-diagnosed BS.Three distinct clusters were identified, with skin-mucosa, gastrointestinal, panuveitis, vascular and CNS subgroups.

Cluster analysis of phenotypes of patients with Behçet's syndrome: a large cohort study from a referral center in China

INTRODUCTION

Behcet's syndrome (BS) is a complex, heterogeneous disorder. However, classification of its subgroups is still debated. The purpose of this study was to investigate the clinical features and aggregation of patients with BS in China, based on manifestations and organ involvements.

METHODS

This was a cross-sectional study of BS patients in Huadong Hospital of Fudan University between September 2012 and January 2020. We calculated relative risks (RRs) of clinical variables according to sex. Moreover, we conducted a hierarchical cluster analysis applied according to eighteen variables to determine subgroups of patients.

RESULTS

A total of 860 BS patients were included. Male sex was associated with ocular involvement (RR 2.32, 95% CI 1.67, 3.22, P < 0.0001), vascular involvement (RR 2.00, 95% CI 1.23, 3.23, P = 0.004), cardiac lesion (RR 5.46, 95% CI 2.33, 12.77, P < 0.0001), and central nervous system involvement (RR 2.95, 95% CI 1.07, 6.78, P = 0.007) and was negatively associated with genital ulcers (RR 0.84, 95% CI 0.79, 0.91, P < 0.0001). Five clusters (C1-C5) were observed. C1 (n = 307) showed the skin and mucosa type. In C2 (n = 124), all had articular involvement, barely having major organ involvement except for 18 cases with intestinal lesions. In C3 (n = 156), the gastrointestinal type, 144 patients presented with intestinal involvement, and 36 patients with esophageal ulcers. In C4 (n = 142), all subjects presented with uveitis. C5 (n = 131) consisted of 44 patients with cardiac lesions, 58 with vascular involvement, and 26 cases having central nervous system involvement.

CONCLUSION

Our analysis confirmed sex differences in phenotypes of BS. Cluster analysis identified gastrointestinal, uveitis, and cardiovascular involvement cluster separately in different subsets, which represents the most commonly involved organs. Further research is required to replicate and clarify the patterns of phenotype in BS.

Uveitis as a potential predictor of acute myocardial infarction in patients with Behcet's disease: a population-based cohort study

OBJECTIVES

To investigate whether uveitis is a predictor of acute myocardial infarction (AMI) among patients with Behcet's disease (BD).

DESIGN

Retrospective cohort study.

SETTING

Patients with BD were retrieved from the whole population of the Taiwan National Health Insurance Research Database from 1 January 2001 to 31 December 2013.

PARTICIPANTS

Among the 6508 patients with BD, 2517 (38.7%) were in the uveitis group and 3991 were in the non-uveitis group.

PRIMARY AND SECONDARY OUTCOME MEASURES

Kaplan-Meier curves were generated to compare the cumulative hazard of AMI in the uveitis and non-uveitis groups. Multivariate Cox regression analysis was used to estimate the adjusted HRs and 95% CI of AMI, and was adjusted for age, gender, systemic comorbidities (eg, hypertension, diabetes, hyperlipidaemia, smoking) and clinical manifestation of BD (eg, oral ulcers, genital ulcers, skin lesions, arthritis and gastrointestinal involvement).

RESULTS

The mean age of the BD cohort was 38.1±15.1 years. Compared with non-uveitis patients, uveitis patients were significantly younger and male predominant. There was no significant difference between the two groups for most proportions of systemic comorbidities and clinical manifestations. The Kaplan-Meier method with the log-rank test showed that the uveitis group had a significantly higher cumulative hazard for patients with AMI compared with the non-uveitis group (p<0.0001). In the multivariable Cox regression after adjustment for confounding factors, patients with uveitis had a significantly higher risk of AMI (adjusted HR 1.87; 95% CI 1.52 to 2.29). Other significant risk factors for AMI were age, hypertension, smoking, and skin lesions.

CONCLUSIONS

Statistical analyses from the nationwide database demonstrated that uveitis is a potential predictor of AMI in patients with BD.

Characteristics and phenotype heterogeneity in late-onset Behçet's syndrome: a cohort from a referral center in China

OBJECTIVES

To evaluate the demographics, clinical aspects, and major organ involvement of patients with late-onset Behçet's syndrome (BS) in a tertiary center in China.

METHODS

We conducted a cross-sectional study of consecutive BS patients in Huadong Hospital of Fudan University from September 2012 to January 2020. We compared clinical variables between patients with disease onset before and after 40 years of age. The relative risks (RRs) of clinical variables were calculated between the two age groups. Moreover, a hierarchical cluster analysis was conducted according to 29 variables to determine homogeneous subgroups in patients with late-onset BS.

RESULTS

We enrolled 152 late-onset BS patients, with a median age at onset of 47 years (interquartile range, IQR: 43-52 years). There is a higher prevalence of intestinal ulcers in late-onset BS than in early-onset BS (RR 1.47), but a lower prevalence of ocular involvements (RR 0.54) and folliculitis (RR 0.46). Female sex was associated with genital ulcers, erythema nodosum, and arthritis. Four clusters (C1-C4) were formed. C1 (n = 71), the largest cluster, was defined as the mucocutaneous group, C2 (n = 20) as the arthritis group, C3 (n = 39) as the gastrointestinal group, in which all patients presented with intestinal lesions, and five cases with esophageal ulcers. In C4 (n = 22), showing a mixture of uveitis and vascular lesions, 15 patients presented with uveitis and 8 had vascular lesions, and 1 case had central nervous system lesions.

CONCLUSION

Four phenotype clusters were identified. Patients with skin lesions comprised the largest cluster, while gastrointestinal, panuveitis, and cardiovascular clusters are the most commonly involved organs in late-onset BS patients. Key Points • Our analysis demonstrated the phenotype discrepancy between early and late onset groups. • Four phenotype clusters were identified, with gastrointestinal, panuveitis and cardiovascular clusters representing commonly involved organs.

Characteristics and Outcomes of Coronary Artery Involvement in Polyarteritis Nodosa

BACKGROUND

Coronary artery involvement is a severe but uncommon manifestation of polyarteritis nodosa (PAN), so clinicians have little knowledge of it. Our aim was to investigate the clinical characteristics, risk factors and outcomes of patients with PAN complicated with coronary artery lesions.

METHODS

Data from 145 patients with PAN who were admitted to Peking Union Medical College Hospital from January 2000 to September 2019 were retrospectively collected.

RESULTS

Nineteen patients (13.1%) had coronary artery lesions due to PAN. The age at the onset of PAN was 32.3 ± 11.8 years. There were no significant differences in common risk factors for coronary arterial atherosclerosis between the patients with coronary artery involvement and those without. Affected branches of the coronary arteries were left anterior descending branch (15 patients), right coronary artery (14 patients), and left circumflex branch (9 patients). Eleven of the 19 patients exhibited multivessel lesions. Multivariate logistic regression analysis showed that celiac artery involvement (odds ratio [OR] 3.722, 95% confidence interval [CI] 1.115-12.427; P = 0.033) and new-onset hypertension (OR 6.668, 95% CI 1.936-22.961; P = 0.003) were risk factors for coronary artery involvement in patients with PAN. Stent placement was performed for 2 patients, and in-stent restenosis occurred in 1 of those patients a year later.

CONCLUSIONS

PAN with coronary artery involvement exhibits more combined involvement of arteries of other organs and more severe diseases. PAN should be considered when treating young adults with an unknown origin of coronary artery lesions. In addition to systemic immunosuppressive treatment, other measures including antiplatelet and anticoagulation therapy should be initiated; however, determining the optimal time to perform procedures such as intervention or surgery is still challenging.

Atypical cardiopulmonary manifestations in pediatric Behçet's disease

BACKGROUND

Behçet's disease (BD) is a multisystem autoinflammatory disease of unknown etiology. Cardiopulmonary involvement is rare, especially in young patients, and carries high morbidity and mortality rates.

AIM

Of 26 patients with pediatric BD enlisted in our center, we encountered three patients with severe atypical cardiorespiratory presentations. Our aim was to describe the manifestations and the course that led to the diagnosis of BD.

RESULTS

Three adolescents presented with intracardiac thrombi and left anterior descending obstruction causing myocardial infarction, pulmonary artery aneurysm with pulmonary embolism in situ, and suspected epiglottitis. Two patients had a delayed diagnosis of BD, and all had a good response to anti-inflammatory agents.

CONCLUSIONS

This study demonstrated that pediatric BD is associated with atypical cardiopulmonary manifestations which maybe life threatening. Since diagnosis maybe challenging, a high index of suspicion is needed especially in young patients, to promptly diagnose and treat these complications. Cardiopulmonary signs and symptoms, though uncommon, maybe the first manifestation and a clue to the diagnosis of this rare disease.

Premature coronary disease, in-stent restenosis and vascular complications in a young man with Behçet syndrome

A young man with a history of early-onset coronary disease presented with an ST-elevation myocardial infarction at the age of 38. He subsequently had recurrent in-stent restenosis requiring repeating interventions and ultimately bypass surgery. After 4 years, he presents with systemic symptoms, new skin lesions and a femoral artery pseudoaneurysm. He is diagnosed with Behçet syndrome, a rare systemic vasculitis characterised by the triad of oral aphthous ulcers, genital ulcers and ocular involvement. Behçet is not associated with premature coronary disease but can have a variety of cardiac complications. Additionally, pathergy, an exaggerated inflammatory response to local injury, is characteristic. We hypothesise that in retrospect, subclinical inflammation and a vascular pathergy likely predisposed him to his cardiac and vascular complications. Here, we review risk factors and presentation of premature coronary artery disease and review the literature on the cardiovascular complications of Behçet syndrome.

Investigation of pregnancy associated plasma protein-A and neopterin levels in Behçet's patients

Behçet's disease (BD) is an autoimmune disease that affects many organs. We aimed to investigate the relationship between BD and these pregnancy-associated plasma protein A (PAPP-A), neopterin, and high sensitive C-reactive protein (hsCRP) parameters. The study included 57 BD patients and 54 healthy controls. After evaluating the active and inactive disease status of the patients, analyzes were performed. When comparing the patient and control groups, neopterin (111.27 ± 37.49; 76.77 ± 38.27 [nmol/L]; P < .001) and hsCRP (11.81 ± 16.8; 3.62 ± 5.06 [mg/L]; P = .001) parameters were significantly higher in patients. Neopterin (117.68 ± 41.67; 94.85 ± 14.75 [nmol/L]; P = .038) and hsCRP (14.68 ± 18.7; 4.47 ± 7.27 [mg/L]; P = .002) found different in active and inactive patients. The sensitivities of neopterin and hsCRP were also found to be high in BD (respectively 93%, 67%). PAPP-A was especially elevated in skin pathologies (P = .02) and neopterin in joint involvement (P = .03). We think that the use of neopterin and hsCRP can help in diagnosis and follow-up of BD.
