KEY POINTS * Both the disease presentation and evidence from basic studies suggest more than one pathogenetic mechanism is involved in Behçet syndrome. Recognized vascular manifestations in
Behçet syndrome include venous claudication, bronchial arterial collaterals (causing haemoptysis) and 'silent' Budd–Chiari syndrome * The diagnostic specificity of certain
manifestations, such as eye disease or vascular involvement, might be more pathognomonic than other manifestations, such as gastrointestinal ulcerations * In considering the clinical and the
basic science findings in Behçet syndrome, the weight of evidence suggests Behçet syndrome should not to be grouped with other, seemingly related, conditions ABSTRACT The presence of
symptom clusters, regional differences in disease expression and similarities with, for example, Crohn's disease suggest multiple pathological pathways are involved in Behçet syndrome.
These features also make formulating disease criteria difficult. Genetic studies have identified _HLA-B*51_ to be the important genetic risk factor. However, the low prevalence of _HLA-B*51_
in many patients with _bone fide_ disease, especially in non-endemic regions, suggests other factors must also be operative in Behçet syndrome. This consideration is also true for the newly
proposed 'MHC-I-opathy' concept. Despite lacking a clear aetiological mechanism and definition, management of manifestations that include major vascular disease (such as
Budd–Chiari syndrome and pulmonary artery involvement), eye disease and central nervous system involvement has improved with the help of new technology. Furthermore, even with our incomplete
understanding of disease mechanisms, the prognoses of patients with Behçet syndrome, including those with eye disease, continue to improve. Access through your institution Buy or subscribe
