Diagnosing Behçet
Area of Science:
- Rheumatology
- Immunology
- Ophthalmology
- Dermatology
Background:
- Multiple diagnostic criteria for Behçet's disease exist, complicating research.
- Lack of standardized criteria hinders international collaboration and data interpretation.
Purpose of the Study:
- To develop new, internationally agreed-upon diagnostic criteria for Behçet's disease.
- To simplify diagnosis and improve the accuracy of Behçet's disease identification.
Main Methods:
- An international study group convened to analyze data from 914 Behçet's disease patients across 7 countries.
- Patient data was compared against control groups from the same centers.
Main Results:
- A new set of diagnostic criteria was proposed.
- The criteria require oral ulceration plus two additional symptoms: genital ulceration, eye lesions, skin lesions, or a positive pathergy test.
Conclusions:
- The new criteria are simpler to implement in clinical practice.
- The proposed criteria demonstrate improved discriminatory performance compared to existing methods.
Abstract:
5 sets of criteria for diagnosis of Behçet's disease are in use--a problem which has hindered interpretation of different studies and collaborative research. An international study group, which included at least one proponent of 4 of the sets, was formed to derive new, internationally agreed diagnostic criteria for Behçet's disease. Data on 914 patients with Behçet's disease, from 12 centres in 7 countries, were compared with controls from the same centres. The new set of diagnostic criteria--which requires the presence of oral ulceration plus any two of genital ulceration, typical defined eye lesions, typical defined skin lesions, or a positive pathergy test--was simpler to use and had an improved discriminatory performance than its predecessors.
