title: One year in review 2016: Behçet's syndrome.
abstract: Several articles highlighting the epidemiology, pathogenesis, clinical features, treatment modalities and disease assessment of Behçet's syndrome (BS) have been published during the last year. Clinical and radiological features of lower extremity deep vein thrombosis due to BS can be quite different than those found in thrombosis due to other causes; additionally, frequency of post-thrombotic syndrome is significantly increased in BS. Some clinical and colonoscopic features are useful in differentiating BS from Crohn's disease. Barkhof criteria may be helpful in differentiating neurologic involvement due to BS from multiple sclerosis. Anatomical localization of papulopustular lesions but not histology has been found to be helpful in differentiating papulopustular lesions of BS from those found in acne vulgaris. Several studies looked at the ovarian reserve with contradicting results. A population-based cohort study found higher risk of hematological malignancies only among female BS patients living in Taiwan. The role of genetic factors and environment is discussed and both autoimmune and autoinflammatory features are underlined in the pathogenesis of BS. New data on the epistatic interactions between ERAP and HLA B51 is available and information on the microbiome have started to appear. New uncontrolled data suggest beneficial effects of anti-TNFs for refractory extra-ocular complications of BS such as pulmonary artery, gastrointestinal and central nervous system involvement. Uncontrolled studies suggest promising results with interleukin-1 inhibition but gevokizumab, a humanised anti IL-1β antibody, failed to meet the primary endpoint of time to first ocular exacerbation in a phase III trial. The debate on anticoagulation continues with new observational data.
