Behcet’s disease is a multisystem autoimmune disease with variable clinial manifestations. The diagnosis may pose a difficult challenge for the clinician, who has to be familiar with the wide spectrum and combination of the symptoms of Behcet’s disease. It is considered a rare disease in Hungary, and there are only few reports on Behcet’s disease in the Hungarian literature. However, the past history of Hungary, the worldwide growing incidence of the disease, and the authors' experience raise the possibility that the occurrence of the disease is higher than previously thought. In this review the authors present and discuss literature data on the pathogenesis and pathomechanism, as well as their own experience concerning the symptomatology of Behcet’s disease in order to promote diagnosis and offer adequate therapy for the patients. The authors presume that the importance of the disease is underestimated in Hungary due to a considerable number of unrecognized cases and they propose to establish a national registry for Behcets disease.

Mycobacterium tuberculosis (MTB) infection has been suggested to contribute to the pathogenesis of erythema nodosum (EN) and nodular vasculitis (NV), the classic forms of panniculitis. However, there is little evidence to demonstrate the presence of MTB in the skin lesions. This study is aimed at evaluating the association between MTB infection and the development of EN and NV in a Chinese population.

The clinical manifestations of Behcet disease (BD) have been reported to differ according to country, region, and race. Gender, onset age, and human leukocyte antigen (HLA)-B51 have also been known as the factors that influence the clinical features of BD. The aim of this study is to investigate the clinical phenotypes of Korean patients who visited the rheumatology clinic with BD with respect to gender, onset age, and HLA-B51.

BACKGROUND: Nonetheless biologic modifier therapies are available treatment strategies for sight-threatening uveitis in children, the lack of evidence from head-to-head randomized controlled studies limits our understanding of timing of therapy when to commence therapy, which agent to choose and how long to continue treatment, and, in case of failure, if switching to another anti-TNF-alpha strategy might be eventually an option. Our aim was to compare the efficacy of Adalimumab when used as first anti-TNFalpha therapy versus Adalimumab used after the failure of a previous anti-TNFalpha (Infliximab) in an open-label, comparative, multi-center, cohort study of childhood chronic uveitis. METHODS: 26 patients (14 F, 12 M; median age: 8.6 years) with refractory, non-infectious active uveitis were enrolled. Due to the refractory course of uveitis to previous DMARD treatment, Group 1 received Adalimumab (24 mg/sq mt, every 2 weeks), as first anti-TNFalpha choice; Group 2 received Adalimumab, as second anti-TNFalpha drug, due to the loss of efficacy of Infliximab, administered after a period of at least 1 year. Both groups received Adalimumab for at least 1 year of treatment. Primary outcome was, once remission was achieved, the time to a first relapse. RESULTS: 14 children (10 with JIA, 3 with idiopathic uveitis, 1 with Behcet’s disease) were recruited in Group 1; 12 children (7 with JIA, 3 with idiopathic uveitis, 1 with early-onset sarcoidosis, 1 with Behcet’s disease) in Group 2. Group 2 showed a lower probability to steroid discontinuation during the first 12 months of treatment (Mantel-Cox chi24.12, p<0.04). In long-term follow-up, Group 1 had higher probability of uveitis remission during the time of treatment on Adalimumab (median +/-SE: 18 +/-1.1 vs 4 +/-0.6 months, CI 95%: 15.6-27.5 vs 2.7-5.2, Mantel-Cox chi210.12, p<0.002). CONCLUSIONS: Even if limited to a relatively small group, our study suggests a better efficacy of Adalimumab when used as first anti-TNFalpha treatment in childhood chronic uveitis.

Behcet’s Disease (BD) is characterized by a relapsing-remitting course, with symptoms of varying severity across almost all organ systems. There is a diverse array of therapeutic options with no universally accepted treatment regime, and it is thus important that clinical practice is evidence-based. We reviewed all currently available literature describing management of BD, and investigated whether evidence-based practice is possible for all disease manifestations, and assessed the range of therapeutic options tested.

Thalidomide is the best-known teratogen worldwide. It was first marketed as a sedative in the late 1950s, but the birth of ∼10 000 children with birth defects resulted in the withdrawal of thalidomide from the market in 1962. Thalidomide embryopathy affects almost all organs but the main defects are concentrated in the limbs, eyes, ears, and heart. Shortly after the withdrawal of thalidomide from the market, its effectiveness in the treatment of erythema nodosum leprosum, an inflammatory condition resulting from leprosy, was reported and since the mid-1990s, the drug has been used widely in the treatment of cancers and autoimmune diseases, among other conditions. 40 000 new cases of leprosy are diagnosed every year in Brazil. Although there is a strict legislation for the prescription and use of thalidomide in Brazil, cases of thalidomide embryopathy have continued to be reported. Here, we present two new cases of thalidomide embryopathy identified in 2011 and review the major clinical findings in the literature that can aid the identification of the embryopathy.

The vitamin D receptor (VDR) gene polymorphisms have been reported to be related to the development of Behcet’s disease (BD). However, the results have been inconsistent among diverse populations. Therefore, this comprehensive meta-analysis has been designed to assess a more accurate association between VDR polymorphisms and BD susceptibility.

A 77-year-old man with a history of cigarette smoking had suffered from vertigo and depression repeatedly for twelve years. He gradually developed bradykinesia in the past half decade and fell down 3 times in the last half year. On admission, he presented with cerebellar ataxia and bulbar symptoms. Brain MRI showed atrophy in the cerebellum and brainstem. 123I-IMP SPECT showed hypoperfusion bilaterally in the cerebellum. Blood examinations showed various elevated inflammatory values and positive for HLA-B51. Cerebrospinal fluid (CSF) revealed aseptic meningitis and increased IL-6 levels. Therefore, we strongly suspected that he had chronic progressive neuro-Behcet’s disease (CPNBD), clinically. Systemic mucocutaneous symptoms appeared 1 month after starting treatments. Pathological findings of his skin biopsy were consistent with Behcet’s disease. It should be kept in mind that both positive HLA-B51 and increased CSF IL-6 levels have the possibility of containing important clues in the diagnosis of CPNBD.
