Behçet’s disease patterns and subsets in a cohort of Egyptian patients

Global demographic and etiological variations of retinal vasculitis: A systematic review and meta-analysis: International Uveitis Study Group (IUSG) Retinal Vasculitis Study (ReViSe) Report 1

This systematic review with meta-analysis explores the global demographic and etiological variations of retinal vasculitis (RV), focusing on differences in frequency, age, sex, and etiology across diverse geographic populations. RV is an inflammatory condition that can lead to visual impairment, making understanding its variations essential for targeted screening and management. Systematic searches were conducted in multiple databases up to February, 2023, following PRISMA guidelines. We included studies with at least 10 RV, such that a frequency measurement can be estimated, without restrictions on publication date or language. RV was categorized as Idiopathic RV in the absence of additional ocular or systemic disease, Syndromic RV for ocular involvement without systemic disease, and Secondary RV with systemic disease. The risk of bias was evaluated using standardized tools. A total of 95 studies, including 23,180 patients, were analyzed. The overall RV frequency among uveitis cohorts was 17%, with European populations showing the highest frequency at 25%. Idiopathic RV accounted for 1% of uveitis cohorts and 38% of RV cohorts, with significant differences across continents. Behçet disease had the highest RV frequency at 56%. The median age of diagnosis was 33.5 years, and RV was more frequent in males (57%). The overall RV frequency among uveitis cohorts was 17%, while Idiopathic RV represented 1% of uveitis cohorts and 38% of RV cohorts. Our findings underscore the considerable geographic and demographic variability in RV, particularly in Idiopathic RV, tuberculosis-related RV, and Behçet disease, highlighting the need for tailored, region-specific, and gender-specific approaches to RV diagnosis and treatment.

Vasculitis damage index in Behçet's disease

BACKGROUND

Vasculitis damage index (VDI) is a validated damage index for systemic vasculitis, and as Behçet's disease is considered one of systemic vascular disease we aimed to study the relationship of the vasculitis damage index to clinical manifestations and comorbidity in patients with Behçet's disease (BD) to determine if VDI could be used to assess damage in patients with BD.

METHODS

A total of 109 patients with BD were recruited from the Rheumatology Department (outpatient and inpatient clinic), Cairo University Hospitals. All patients were subjected to full history taking, clinical examination, and routine laboratory investigations. Disease activity was assessed by the BD current activity form, and the VDI was calculated in all patients. The relationship of the VDI to the disease clinical manifestations was studied. Mann-Whitney and Kruskal Wallis tests were used to estimate differences in quantitative variables. Spearman correlation test was used to test for correlation between quantitative variables.

RESULTS

In the current study, the VDI ranged from 1 to 10, with a mean of 3.5 ± 1.8. It was significantly associated with total thrombosis (P = 0.022); total neurological manifestations (P = 0.000), especially stroke and cranial nerve affection; uveitis (P = 0.005); avascular necrosis (AVN) (P = 0.015); osteoporosis (P = 0.01); impaired vision (P < 0.0001); cataract (P < 0.0001); and diabetes (P = 0.012). Generally, immunosuppressive treatment was significantly associated with VDI (P = 0.039), especially cyclophosphamide (P < 0.0001), biological agent (P = 0.008), chlorambucil (P = 0.003), and anticoagulant (P = 0.02). VDI was also significantly correlated with age (P = 0.033), disease duration (P = 0.029), and duration of eye involvement (P = 0.003).

CONCLUSION

VDI is significantly associated with most disease parameters of BD, except for parameters such as mucocutaneous manifestations and uncomplicated venous thrombosis; however, further studies may be needed to establish BD-specific damage index.

The pattern of cardiovascular manifestations in Egyptian Behçet’s patients and its relation to disease activity

Background

Behçet’s disease (BD) is also referred to as vascular BD when it frequently involves the heart and vessels. This study aimed to describe the cardiovascular manifestations in patients with BD and its correlation to disease activity. We conducted a cross-sectional study on 40 patients diagnosed with BD according to the International Criteria for Behçet’s Disease 2014. All the patients were subjected to detailed history taking, full clinical examination, lab investigations, resting electrocardiogram, trans-thoracic echocardiography, and carotid artery duplex for measuring intimal thickness, peripheral arterial and venous duplex, computed tomography pulmonary angiography, and full ophthalmological examination. Regarding the activity of the disease, it was assessed according to the score of Behçet’s Disease Current Activity Form (BDCAF).

Results

The most common cardiac manifestation was valvular lesion (67.5%) where the most frequently affected valve was the tricuspid valve (27.5%). Although 25% of patients had left ventricular diastolic dysfunction, only 5% had intracardiac masses. Approximately 52.5% of patients had vascular lesion (deep venous thrombosis 45%, arterial involvement 7.5% [as pulmonary artery thrombosis 5% and aneurysm 2.5%]). Increase in intima media thickness (IMT) was observed in 7.5% of patients, while 60% had abnormal lipid profiles. Hypercholesterolemia was the most common lipid abnormality (50%). BDCAF score range was 4–12, which was significantly correlated to multiple cardiovascular parameters as a mitral, tricuspid valve, and vascular venous involvement (p < 0.05), while not significantly correlated to lipid profile (p > 0.05).

Conclusion

Cardiovascular complications are frequent among patients with BD, even those who are asymptomatic; therefore, these complications must be screened for early detection and proper management.

Behçet's disease in Iraq: new insights into the clinical and epidemiologic features in Middle-Euphrates region

Objectives: Behçet's disease (BD) is a chronic multisystem disease that is classified as a vasculitis. Recent evidence shows that BD is an inflammatory disease at the crossroad between autoinflammatory and autoimmune syndromes. The objective of this study was to determine BD awareness in Iraq, assess the demographic variables, and observe the initial and major clinical manifestations.Methods: A cross-sectional study was conducted, including 105 patients, aged between 15 and 60 (mean 33.9) years, 57 males (54.3%) and 48 females (45.7%). All patients fulfilled the CIBD diagnostic criteria.Results: About 50% of patients were diagnosed by rheumatologists. Male to female ratio was 1.18:1, with evident female preponderance in patients diagnosed before 20 years old. The most frequent onset sign was oral aphthae. Ocular, genital, skin, neurologic and joint involvement followed in frequency.Conclusion: both doctors' and patients' awareness of BD is increased in Iraq. Early-onset BD tends to involve females more than males with a significant drop of male-to-female ratio as compared to previously reported in national and other Middle-Eastern studies. The clinical characteristics are comparable to those reported from other countries with higher neurologic involvement as compared to previous national reports.
