Objectives:
The progression of Behçet's disease (BD) from a mucocutaneous-limited form to major organ involvement (MOI) represents a significant challenge. This study aims to identify patients without MOI at BD onset who are at increased risk of developing MOI in later stages.
Methods:
Patients' data were drawn from the International AutoInflammatory Disease Alliance (AIDA) Network registry dedicated to BD.
Results:
A total of 328 patients with exclusively mucocutaneous manifestations at BD onset were enrolled. Of these, 82 patients (25%) developed MOI over the entire follow-up period. Patients with minor oral aphthosis and no major oral aphthosis exhibited a reduced risk of developing MOI, with an odds ratio (OR) of 0.41 [95% confidence interval (95%CI): 0.22-0.79, P = 0.008]. Conversely, patients with both major and minor oral aphthosis had a significantly higher risk of developing MOI, with an OR of 12.76 (95%CI: 1.44-113, P = 0.02). Moreover, the development of MOI was associated with major oral aphthosis plus genital aphthosis (OR: 2.49, 95%CI: 1.1-5.6, P = 0.03), major oral aphthosis plus pseudofolliculitis (OR: 2.9, 95%CI: 1.15-7.4, P = 0.02) and major oral aphthosis plus both genital aphthosis and pseudofolliculitis (OR: 3.73, 95%CI: 1.22-11.4, P = 0.02). A positive family history for BD was associated with MOI (OR: 2.85, 95%CI: 1.08-7.58, P = 0.03).
Conclusion:
A positive family history and the presence of major oral aphthosis combined with minor oral aphthosis, genital aphthosis or pseudofolliculitis are associated with MOI development in patients with mucocutaneous BD at onset.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
