Behçet's disease (BD) is a chronic relapsing vasculitis that affects vessels of all types and sizes with a broad spectrum of phenotypic heterogeneity and complex immunopathogenesis. Efforts by the scientific community to resolve the unmet needs of BD and gaps in our knowledge have been hampered by considerable challenges that primarily relate to the rare nature of the disease in many parts of the world and its heterogeneity. Controversies remain in many aspects of the disease including the diagnostic criteria, immunopathogenesis and biomarker discovery, geographical variation, and therapeutic considerations. In this review, we highlight recent advances in our scientific understanding of BD, shed new insights into diagnostic and treatment strategies, and discuss residual gaps in our knowledge that will serve as the basis for current and future research.
New insights into Behçet's disease in Ireland: the Midwest cohort study

OBJECTIVES: The epidemiology of Behçet's disease (BD) remains poorly understood with limited international data on disease burden, progression and treatment outcomes. The aims of this study were to determine the natural history of BD in the Midwest region of Ireland and compare our findings with those from other European and Mediterranean studies.
METHODS: We established a cohort of patients with BD in the Midwest Region of Ireland based on ISGBD and/or ICBD criteria. Longitudinal data were captured on demographic and clinical characteristics, disease activity and clinical outcomes.
RESULTS: The cohort included 24 Caucasian patients (16 women, 8 men) and one male patient with Middle Eastern ancestry, who satisfied the diagnostic criteria for BD. Based on the ISGBD criteria, the point prevalence of BD was 6.2 per 100,000 population. The most common clinical manifestation was oral aphthosis (100%) followed by genital aphthosis (92%) and skin lesions (92%), arthralgia/arthritis (40%), ocular involvement (32%), vascular thrombosis (12%) and pathergy phenomenon (8%). Only 1 patient was HLA-B*51 positive. A long-term multidisciplinary approach that included physician specialists, nurse specialists, and general practitioners was adopted for ongoing patient care.
CONCLUSIONS: The prevalence of BD in Ireland is higher than previously reported with a significant proportion experiencing laryngeal destruction. There are many similarities as well as several differences in the epidemiology of BD by country and indeed within countries. We fully advocate the need for national and international collaborative efforts in order to further understand the complex aetiology and immunopathology of BD in order to improve the clinical, physical, psychological wellbeing of patients.
Fulltext High Vitamin D Levels May Downregulate Inflammation in Patients with Behçet's Disease

Vitamin D plays a significant role in the immune system modulation and may confer a protective role in autoimmune diseases. We conducted a case-control study to compare 25(OH)D levels in patients with BD who were managed at a regional rheumatology programme in the midwest region of Ireland compared to matched controls. Healthy controls were selected from the Irish health system and matched in 1 : 5 ratio for age, sex, and the month of the year. 25(OH)D levels <20 nmol/L were classified as deficient while levels between 20 and 40 nmol/L were classified as insufficient. Differences between groups were assessed using Mann-Whitney test and associations between cases and controls were expressed as odds ratios and 95% confidence intervals. Nineteen patients with BD were compared with 95 controls matched by age, sex, and month of blood draw. 25(OH)D levels were significantly higher in patients in BD than in matched controls (median values: 45 nmol/L versus 22 nmol/L, p < 0.005) and tended to be lower in patients with active disease than in those without (median values: 35 nmol/L (IQR: 22.75-47.25 nm/L) versus 50 nmol/L (IQR: 35-67 nmol/L), p = 0.11). Compared to controls, patients with BD were significantly less likely to have 25(OH)D deficiency or insufficiency (OR: 0.09, 95% CI: 0.03-0.28, p < 0.001). Our findings suggest a possible role for 25(OH)D in modifying the inflammatory response in BD and uncover a potential opportunity to assess whether correction of Vit D deficiency confers protective benefits.
Fulltext The real-world use of different anti-tumor necrosis factor agents in a Northern European population of patients with Behçet's disease

Adeeb F, Ng WL, Khan MU, Devlin J, Stack AG, Fraser AD

Eur J Rheumatol, 2017 Dec;4(4):254-259.
PMID: 29308279 DOI: 10.5152/eurjrheum.2017.17046

Objective: The aim of this study was to evaluate prescription practices, treatment responses, and serious adverse events of anti-tumor necrosis factor (anti-TNF) therapies in Behçet's disease (BD).
Material and Methods: Patients with BD satisfying the International Study Group for Behçet's Disease or the International Criteria for Behçet's Disease criteria were recruited from a regional rheumatology program. The choice of anti-TNF, treatment response, and adverse events were specified. Response to treatment was evaluated by the detection of new, worsening, or improving clinical features, and management was benchmarked against current The European League against Rheumatism recommendations published in 2008.
Results: Out of the total of 22 patients, 18 (81.9%) received anti-TNF therapies, resulting in 14 (77.8%) complete and 4 (22.2%) partial remissions. Eleven (61.1%) patients switched to a second anti-TNF, seven patients (38.9%) required three different anti-TNFs, and one required a fourth anti-TNF to achieve remission. Two patients required retrials before their disease was controlled. Anti-TNF therapy included infliximab (IFX): n=15, 83.3%; adalimumab (ADA): n=9, 50%; golimumab: n=6, 33.3%; etanercept: n=5, 27.8%; and certolizumab pegol: n=2, 11.1%. Secondary failure was observed with IFX (4/15; 26.7%) and ADA (2/9; 22.2%), and these (100%) were manifested after at least 2 years of treatment. Five patients with potentially life-threatening laryngeal involvement received anti-TNFs successfully halting disease progression. Five allergic reactions were encountered, and five serious infections were documented involving three patients aged ≥ 50 years, all with the use of IFX.
Conclusion: Anti-TNF therapy induced a clinical response in 100% patients and achieved complete remission in 78% patients. It provides an effective alternative option for first-line therapy in severe BD where many conventional immunosuppressive therapies fail. Patients with BD who do not respond to one or more anti-TNFs because of intolerance, ineffectiveness, or secondary failure might benefit from switching to another drug from this group or even a retrial of a previously administered anti-TNF because unsatisfactory results with one biologic is not predictive of response to another anti-TNF. For those with potentially life-threatening destructive laryngeal manifestation, anti-TNF as a first choice may be considered.
