Abstract
BACKGROUND Ankylosing spondylitis (AS) and Behçet's disease (BD) are distinct inflammatory disorders, but their coexistence is a rare clinical entity. This case sheds light on managing this complex scenario with Janus kinase (JAK) inhibitors. CASE PRESENTATION A 42-year-old woman presented with a decade-long history of lower back pain, nocturnal spinal discomfort, recurrent eye issues, oral and genital ulcers, hearing loss, pus formation in the left eye, and abdominal pain. Multidisciplinary consultations and diagnostic tests confirmed AS (HLA-B27 positivity and sacroiliitis) and BD (HLA-B51). Elevated acute-phase markers were observed. CONCLUSION This case fulfills diagnostic criteria for both AS and BD, emphasizing their coexistence. Notably, treatment with upadacitinib exhibited promising efficacy, underscoring its potential as a therapeutic option in patients with contraindications for conventional treatments. Our findings illuminate the intricate management of patients presenting with these two diverse systemic conditions and advocate for further exploration of JAK inhibitors in similar cases.

Abstract
Behçet's disease (BD) is a systemic vasculitis that frequently presents with a relapsing-remitting pattern. CNS involvement (Neuro-Behçet) is rare, affecting approximately 10% of patients. Its etiological mechanisms are not yet fully understood. The most commonly accepted hypothesis is that of a systemic inflammatory reaction triggered by an infectious agent or by an autoantigen, such as heat shock protein, in genetically predisposed individuals. Mycobacterium tuberculosis is known to be closely interconnected with BD, both affecting cell-mediated immunity to a certain extent and probably sharing a common genetic background. We present the case of a 34-year-old Caucasian woman who had been diagnosed with tuberculous meningitis 15 months prior, with significant neurological deficits and lesional burden on MRI with repeated relapses whenever treatment withdrawal was attempted. These relapses were initially considered as reactivation of tuberculous meningoencephalitis, and symptoms improved after a combination of antituberculous treatment and corticosteroid therapy. After the second relapse, the diagnosis was reconsidered, as new information emerged about oral and genital aphthous lesions, making us suspect a BD diagnosis. HLA B51 testing was positive, antituberculous treatment was stopped, and the patient was started on high doses of oral Cortisone and Azathioprine. Consequently, the evolution was favorable, with no further relapses and slow improvements in neurological deficits. To our knowledge, this is the first report of Neuro-Behçet's disease onset precipitated by tuberculous meningitis. We include a review of the available literature on this subject. Our case reinforces the fact that Mycobacterium tuberculosis infection can precipitate BD in genetically predisposed patients, and we recommend HLA B51 screening in patients with prolonged or relapsing meningoencephalitis, even if an infectious agent is apparently involved.

Abstract
OBJECTIVE To investigate the differential diagnostic spectrum in patients with suspected Behçet's syndrome (BS) in low prevalence regions. In addition, the number of patients fulfilling the ICBD criteria despite not having BS was evaluated. METHODS This retrospective analysis was performed in two referral centres for BS. Patients with confirmed BS (clinical diagnosis with fulfilment of ISG criteria or a score of ≥5 points in the ICBD criteria) were excluded. The remaining patients were divided into 11 differential diagnosis categories. If no definitive alternative diagnosis could be established, patients were termed 'probable BS' in case of (i) relapsing orogenital aphthosis in the absence of other causes and either HLA-B51 positivity, or origin from an endemic area or presence of an additional typical BS symptom that is not part of the classification criteria, or (ii) with 3-4 points scored in the ICBD criteria. RESULTS In total 202 patients were included and categorized as follows: 58 patients (28.7%) as 'probable BS', 57 (28.2%) skin disease, 26 (12.9%) chronic pain syndrome, 14 (6.9%) eye disease, 11 (5.4%) spondyloarthropathy, 9 (4.5%) gastrointestinal disease, 7 (3.5%) neurological disease, 4 (2%) arthritis, 3 (1.5%) auto-inflammation, 3 (1.5%) connective tissue disease and 10 (5.0%) miscellaneous disease. HLA-B51 was positive in 55/132 (41.7%); 75/202 (37.1%) of the patients fulfilled the ICBD criteria. CONCLUSION In a low disease prevalence setting, the straightforward application of the ICBD criteria may lead to overdiagnosis of BS. The differential diagnosis of BS is enormously broad. Clinicians should be aware that HLA-B51 positivity is still not considered as a diagnostic feature in BS.

Abstract
Behçet's disease (BD) is a multi-system inflammatory disorder with vasculitic features. It does not suit any of the current pathogenesis-driven disease classifications well, a unifying concept of its pathogenesis is not unanimously conceivable at present, and its etiology is obscure. Still, evidence from immunogenetic and other studies supports the notion of a complex-polygenic disease with robust innate effector responses, reconstitution of regulatory T cells upon successful treatment, and first clues to the role of an, as of yet, underexplored adaptive immune system and its antigen recognition receptors. Without an attempt to be comprehensive, this review aims to collect and organize impactful parts of this evidence in a way that allows the reader to appreciate the work done and define the efforts needed now. The focus is on literature and notions that drove the field into new directions, whether recent or more remote.

Abstract
This case discusses a 10-year-old boy who presented in significant respiratory distress with cardiac tamponade with associated gross ascites and hepatomegaly, requiring urgent transfer for pericardiocentesis. On further investigation, he was found to have multiple pulmonary emboli and evidence of panserositis. An underlying rheumatological cause was suspected in the absence of any evidence of infection or malignancy, and blood tests were positive for anti-double stranded DNA, anticardiolipin and antiglycoprotein antibodies as well as HLA B51. In his medical history, he has previously had mouth ulcers, chronic anaemia of undetermined cause and erythema multiforme. These symptoms, along with clinical presentation, mean a diagnosis of Behcet's disease and associated antiphospholipid syndrome was felt to be most likely. Anticoagulation therapy was commenced for treatment of the emboli, and colchicine was started for management of Behcet's disease. The patient was discharged clinically well from the hospital and continues under specialist rheumatological and haematological follow-up.

Abstract
Purpose: To report an unusual presentation with kyrieleis like plaques in a patient with ocular Behcet’s disease. Case presentation: A 28-year-old young male presented with blurring of vision in the left eye, fundus examination revealing focal segmental intra-arterial plaques involving all branches of retinal artery characteristics of kyrieleis-like plaques with no features of retinitis in retinal periphery and mild vitritis. All routine investigations were normal, the patient testing positive for HLA-B51 marker, diagnosed as a case of ocular Bechet’s disease and managed with oral steroids and immunosuppressive agents. Results: The patient had good recovery of vision with substantial resolution of intra-arterial plaques. Conclusion: Ocular Bechet’s disease can present with uncommon features of kyrieleis like plaques. Ophthalmologists need to be vigilant for the presence of such potential ocular manifestations as the likely initial presentation in order to obtain early diagnosis and initiate timely management.

Abstract
OBJECTIVES Juvenile Behçet's disease is a rare and severe disease of childhood characterized by a chronic inflammatory vasculitis. The aim of the present study is reporting demographic, clinical and therapeutic outcomes of juvenile Behçet's disease in a tertiary center. METHODS The retrospective study included patients who were diagnosed Behçet's disease before 16 years. The demographic and clinical features, and diagnostic and therapeutic strategies of patients were recorded. RESULTS Seventy-two patients with jBD were included in this study; 32 were male (44.4%). Thirty (41.7%) patients had BD cases in their family. We observed oral ulceration (100%), genital ulceration (68.1%), joint involvement (36.1%) and cutaneous manifestations (34.7%) as the most common clinical findings, respectively. As severe organ involvements, 20.8% ocular, 18.1% vascular and 15.3% neurologic pathologies were seen. All patients had colchicine. Corticosteroid (20.8%) was used to treat severe cases and acute attacks. Azathioprine (23.6%) was the main immunosuppressive agent and cyclophosphamide (8.3%) was applied initially for life-threatening conditions with pulse methylprednisolone. CONCLUSION In this cohort, the prevalence of genital ulceration and family history was high, and we observed less ocular involvement, a few permanent neurological morbidities and no death. Key Points • In the present study, there were acceptable permanent neurological involvements as morbidity and no mortality. • It is important noticing and managing jBD in early phase in order to prevent the devastating results. • The awareness of jBD provides timely treatment of patients. • The positivity of family history and HLA B51 should alert the clinician about the incomplete cases.

Abstract
BACKGROUND/AIMS 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. METHODS Total 193 Korean patients (129 females and 64 males) fulfilling the international criteria for BD were retrospectively assessed. RESULTS The mean age at disease onset and disease duration of the BD patients were 32.2 ± 11.1 and 14.2 ± 9.3 years, retrospectively. Females suffered more frequently from genital ulcers (90.7% vs. 75.0%, p < 0.01), peripheral arthritis (67.4% vs. 43.8%, p < 0.01), and inf lammatory low back pain (38.8% vs. 23.4%, p = 0.03) than males, while skin involvement was more frequent in males than in females (90.6% vs. 75.2%, p = 0.01). The patients with late onset of BD (> 40 years) suffered from neurologic involvement (15.9% vs. 4.2%, p = 0.007) more frequently than those with early onset of BD. The patients with HLA-B51 showed earlier onset of disease than without HLA-B51 (28.3 ± 11.4 years vs. 33.8±11.6 years, p = 0.02) and the neurologic and gastrointestinal involvements were more frequent in the patients without HLA-B51 than with HLA-B51 (17.2% vs. 2.5%, p = 0.02 and 20.7% vs. 2.5%, p = 0.01, respectively). CONCLUSION The clinical phenotypes in Korean patients with BD may be influenced by gender, onset age and HLA-B51.

Abstract
Psoriasis arthropathy (PsA) is a chronic inflammatory arthropathy characterized by the association of arthritis with psoriasis. Although the precise mechanisms of PsA still remain obscure, several genetic and environmental factors have been suggested to play important roles. HLA-B51 has been strongly associated with Behçet's disease; however, its association with PsA has not been documented. We describe herein five Japanese patients (4 males and 1 female) with PsA and positive for HLA-B51. The clinical forms defined by Moll and Wright revealed that the polyarticular pattern was noted in two cases, and oligoarticular, distal, and spondyloarthropathy patterns were noted in one case each. Positive rheumatoid factor was detected in one patient, and antinuclear antibody in two patients. The other HLA subclasses were A2 and A31 in 3 cases, respectively. HLA-B51 was detected in 5 out of 17 patients with PsA examined in our department; in contrast, HLA-B51 was not detected in 17 patients with psoriasis vulgaris. Our observations suggest that HLA-B51 may play a role in the pathogenesis of PsA in the Japanese population.

Abstract
We report on a patient who presented at our hospital with fever, headache, neck pain, partial nuchal rigidity and decreased vision of the left eye. The clinical history, biochemical and instrumental exams performed suggested meningitis but the final hypothesis achieved was an unusual case of Neuro-Behcet-Disease (NBD) without orogenital ulcerations at presentation and with normal MRI findings, whose course was complicated by fatal cerebral venous sinus thrombosis and intracranial haemorrhage. The post-mortem results confirmed the diagnosis. This is a rare case confirmed by anatomo-pathological findings where NBD can present itself as an acute meningeal syndrome that mimics central nervous system infections, making diagnosis difficult and delaying treatment.

Abstract
Clinical phenotypes of Behçet disease (BD) vary among ethnic groups. We chronologically analyzed the clinical manifestations of BD in 412 patients meeting the Japanese criteria for BD seen at 2 Yokohama City University hospitals from July 1991 to December 2007. We examined the onset of individual symptoms in each patient. A single initial symptom appeared earlier than any other manifestation in 78% of the patients. Time from the initial symptom to diagnosis was 8.6 ± 10.1 years. Oral ulcer, the most common initial manifestation, preceded the diagnosis by 7.5 ± 10.2 years. Genital ulcer and eye and skin involvement appeared 1 or 2 years before diagnosis, whereas gastrointestinal, central nervous system, or vascular involvement developed later. The frequency of eye involvement was significantly higher in patients with neurologic lesions, but significantly lower in those with gastrointestinal or vascular involvement. However, no particular combination of major symptoms predicted the development of organ involvement. There has been a recent decrease in the rate of "complete" BD (patients having all 4 of the major symptoms of oral ulcers, genital ulcers, and eye and skin lesions), whereas the frequencies of arthritis, gastrointestinal, and vascular involvement have been increasing. Further assessment may allow the detection of early predictors of the more aggressive disease, which requires more intensive treatment.

Abstract
OBJECTIVES We investigated the prevalence of Behçet's syndrome (BS) among the ethnic Armenians in Istanbul using Familial Mediterranean Fever (FMF) as a comparator disease. We also studied HLA-B51 and MEFV mutations among a group of healthy Armenians and a non-Armenian population. METHODS The prevalence study was conducted in 2 parts in the Armenian primary schools in Istanbul, using the enrolled students as index cases to study the core family. In Part I, a questionnaire seeking only whether either parent had previously been diagnosed as having BS or FMF by a physician was distributed to a total of 1873 index students registered at 10 schools. A total of 1380 parents filled in the questionnaire, yielding a response rate of 37% (1380 / 3746). In Part II, eight schools participated with a response rate of 83 % (1183/1428). Also, genomic DNA samples of 108 healthy (14 M/94 F) Armenians and 97 (45 M/ 52 F) non-Armenians, were studied for HLAB51 and MEFV gene mutations. RESULTS In Part I, none of the parents turned out to have been diagnosed as BS, whereas a total of 12 / 1380 (870/105) had been diagnosed as FMF. In the second part the estimated prevalence of BS was 90 /105 and that of FMF was 760/ 105. HLA-B51 carrier rate was found to be similar between the Armenian (27%, 29/108) and the non-Armenian participants (19%, 18/97), (p=0.158). Overall carrier rate of MEFV gene mutations was significantly higher in the Armenian group (36% vs. 20%, p=0.015). CONCLUSIONS The genetic load for FMF is considerably higher among the Armenians when compared to the load for BS among the same ethnic group. On the other hand, the rather low frequency of BS among the Armenians when compared to the frequency among the general population living in the same environment is further evidence for a genetic predisposition to BS. HLA- B51 does not seem to play a dominant role in the said predisposition. Finally, as we have used an unorthodox epidemiological methodology in data collection our results might need to be further verified by more conventional methods.

Abstract
OBJECTIVE This study was performed to examine the influence of tumour necrosis factor-alpha (TNFalpha) promoter polymorphisms on disease susceptibility and clinical features of Behçet's disease (BD) and the association between TNFalpha polymorphisms and human leucocyte antigen (HLA)-B51. METHODS We examined 115 patients with BD and 114 healthy subjects. Six single nucleotide polymorphisms (SNPs) of the TNFalpha promoter at positions -1031, -863, -857, -308, -238, and -646 were analysed using automated sequencing. We compared the frequencies of alleles and genotypes in patients with BD and controls using the chi(2)-test or Fisher's exact test. Haplotype frequency was also assessed using the chi(2)-test. RESULTS We found no significant differences in the frequencies of polymorphic genotypes and alleles of the TNFalpha promoter region between BD patients and controls. The resulting haplotype frequencies of the BD patients were also not significantly different from those of controls. None of the TNFalpha promoter polymorphisms analysed here were associated with clinical features. Patients with the novel -646A allele of the TNFalpha promoter region were significantly associated with the expression of the HLA-B51 allele (p(corr) = 0.006), although this novel polymorphic allele was not associated with BD susceptibility. CONCLUSION The novel -646A TNFalpha allele was associated with the expression of HLA-B51 in Korean BD, although we found no genetic role of TNFalpha promoter polymorphisms in the susceptibility to BD. Further studies to examine the contributions of this gene polymorphism and HLA-B51 to the susceptibility to BD in large populations are required.

Abstract
OBJECTIVE Studies from Israel and Turkey have proposed that patient clusters with discriminating clinical features may exist in Behçet's disease (BD); such clusters could help to better understand pathogenetic mechanisms and guide therapeutic decisions. Herein, we searched for specific associations between each disease manifestation to all other manifestations in Greek patients with BD. METHODS Specific clinical features were retrospectively recorded in 142 consecutive patients (80 men) fulfilling the International Study Group criteria, seen between 2000-2008 in our Departments (mean follow-up of 37 months). All possible associations between distinct clinical features were examined; further analysis in relation to HLA-B51 status and pathergy test positivity, available in 89 patients, was performed. RESULTS No significant associations between various manifestations of BD were found, either among all patients, or among men or women analysed separately. Uveitis was present more frequently in men, but not women, who were HLA-B51 carriers (p<0.02). A positive pathergy reaction was associated with oral ulcers (p<0.001) and central nervous involvement (p=0.008) in women, and folliculitis in men (p=0.046). CONCLUSION In contrast to studies from other countries, no subgroups of patients with distinct positive or negative associations between clinical features were found. HLA-B51 may have some prognostic significance in men only. Whether differences in disease expression between geographical areas may reflect different triggers of pathogenetic mechanisms operating among ethnic groups could be further explored in comparative studies.

Abstract
OBJECTIVE To study HLA class I and class II association in Tunisian patients with reactive (ReA) and undifferentiated arthritis (UA). METHODS The study included 17 patients with ReA defined according to the European Spondylarthropathy Study Group criteria for spondylarthropathy (SpA), 11 patients classified as having undifferentiated arthritis and 100 unrelated healthy controls. HLA class I antigens were typed serologically and HLA class II alleles were genotyped molecularly by the polymerase chain reaction with sequence-specific primers technique. RESULTS There was a major difference between HLA alleles in ReA and UA patients when compared separately with controls. Increased frequencies of HLA-B27 (p=7.76 10-12, OR=59.30), HLA-B51 (p=0.015, OR=4.91) and HLA-DRB1*04 (p=0.033, OR=2.90) alleles were found in patients with ReA but not in patients with UA. HLA-B27 was not expressed totally in our cohort of UA patients. A significant increase of HLA-B15 (p=0.002, OR=18.40) and a moderate increase of HLA-B7 (p=0.043, OR=5.15) was found in patients with UA, but not in patients with ReA. In the B27 negative patients, HLA-DRB1*04 association with ReA was found independently of B27. CONCLUSION Our data confirmed a significant association of HLA-B27 with ReA in the Tunisian population. Our results also suggested that some of the additional HLA antigens were associated with ReA including HLA-B51 and HLA-DRB1*04 alleles. UA seemed to have a genetic background different from ReA in Tunisian patients.

Abstract
OBJECTIVE To evaluate the activation status of circulating CD4+, CD8+, and gammadelta T cells in patients with active and inactive Behçet's disease (BD). METHODS We studied 11 subjects with active BD, 28 with inactive BD, and 13 healthy controls. The expression of CD4, CD8, pan-gammadelta, Vdelta1, and Vdelta2 along with the early activation marker CD69 was analyzed by 3-color flow cytometry. RESULTS Proportions of activated CD8+ and gammadelta T cells were significantly greater in patients with active BD than in those with inactive BD or healthy control subjects, but the proportion of activated CD4+ T cells did not differ among these 3 groups. In addition, significantly greater proportions of the Vdelta1+ and Vdelta2+ gammadelta T-cell subsets were activated in patients with active BD than in those with inactive BD or healthy controls; in active BD, the balance of activation between these subsets favored the Vdelta1+ T cells. No significant differences in these proportions were found between subjects with inactive BD and healthy controls. These findings were observed exclusively in patients with HLA-B51. A comparison of samples from 5 patients taken during active BD and after resolution of BD-related symptoms showed the proportions of activated CD8+ and gammadelta T cells dropped when the patients' BD became inactive. CONCLUSION CD8+ and gammadelta T cells, rather than CD4+ T cells, were activated in vivo in patients with active BD and HLA-B51, but not in those with inactive BD, suggesting that these potentially cytotoxic T cells play a critical role in BD flares.

Abstract
Behçet's disease (BD) is a complex of symptoms, which include aphthae in the oral mucous membrane, eruptions of the skin, ulcers on genitals and eye symptoms. The disease relapses into acute episodes for many years and involves internal organs. Since 1990, BD has been diagnosed by the international diagnostic criteria. During the last 20 years, BD has varied in the disease expression. The number of patients who fill the diagnostic criteria falls, while the number who do not fill the diagnostic criteria increases. Complications of internal organs are unchanged. Investigations have disclosed many new findings on the pathogenesis; the close relationship of BD with HLA-51 gene and participation of Streptococcus sanguinis in the oral cavity seems to be significant for diagnosis and treatment. For these reasons, the Japanese study group presented a set of new extended diagnostic criteria in 2005 with guidance for suitable treatment. BD is rare in the Nordic countries, but increased communication with Middle-Eastern countries is likely to cause an increase in the number of BD patients. We must refresh and renew our knowledge of BD.

Abstract
Behcet's disease (BD) is thought to be caused by multiple genetic, environmental and immunological factors, one of the most prominent being the strong association with human leucocyte antigen (HLA)-Bw51, an HLA-Bw4-associated allele. We examined the presence/absence of 14 killer cell immunoglobulin-like receptors (KIRs) and their ligands in 134 Turkish individuals with BD and compared the results with those of 154 ethnically matched controls. Although KIR3DL1 with its ligand (HLA-Bw4) was significantly increased in the patients with BD (P = 0.0003), this no longer applied when the patients and controls were categorised by HLA-Bw51 status. Thus, no association was identified between presence or absence of any of the 14 KIR genes studied and BD. In addition, we did not find any associations of KIR with various manifestations of the disease nor with gender or age of onset.

Abstract
OBJECTIVES To analyze demographic, clinical and genetic features of Behçet's disease (BD) in Tunisia and to compare them with other ethnic and geographic groups. METHODS Two hundred and sixty patients with BD (International Study Group criteria) received in the Department of Internal Medicine of the University Hospital La Rabta in Tunisia, from 1987 to 2006, were retrospectively studied. Demographic, clinical, and genetic data were recorded and analyzed using SPSS 11.0. RESULTS The cohort consisted of 188 males and 72 females (M/F = 2.61). The mean age at the onset of the disease was 29 years. Oral and genital ulcers (GU) were seen in 100% and 83% respectively. The most other common clinical features of BD were ocular involvement (51%), arthritis (38.8%), venous thrombosis (33%) and neuropsychiatric symptoms (24.2%). Only 1.5% had gastrointestinal lesions. HLA-B51 frequency was significantly higher in patients with BD (54% vs. 25.5% in healthy controls, p < 0.05). DVT and pseudofolliculitis were significantly more frequent in men whereas arthritis and erythema nodosum were significantly more frequent in women. DVT was also significantly more frequent in patients with GU and those with neurological involvement. GU, positive pathergy test and DVT were significantly less frequent in patients with ocular involvement. Neurological involvement consisted of 47 cases with CNS parenchymal lesions and 22 with cerebral vascular lesions (13 had both lesions); HLA B51 was significantly less frequent in patients with neurological involvement. CONCLUSION Our series was characterized by particular aspects such as high frequency of DVT and neuropsychiatric involvement, and rare occurrence of gastrointestinal lesions. The results confirm the ethnic and geographic variation of BD expression.

Abstract
Behçet's Disease (BD) is a multisystemic inflammatory disorder as a triad of symptoms including recurrent oral and genital aphthous ulceration, and uveitis with unknown pathogenesis. Many researchers have tried to investigate the association of HLA-B51 gene with the BD. We aimed to investigate the association of the HLA-B51 gene and its expression, also polymorphic structure by PCR, RT-PCR and sequence specific oligonucleotide primers and probes in BD patients (n: 35) and control group (n: 50). According to our results, we did not observe any association in between HLA-B51 gene, its polymorphism, expression and BD patients.

Abstract
The acne lesions characteristic of Behçet's syndrome are not sterile and are commonly observed in combination with arthritis. The two main nodular skin lesions--superficial thrombophlebitis and erythema nodosum--are equally frequent, and rather difficult to distinguish. Superficial thrombophlebitis is usually observed in combination with thrombosis in large veins, and thrombosis of the large veins usually clusters with dural sinus thrombi, which make up approximately 20% of all central nervous system (CNS) lesions of Behçet's syndrome. The remaining CNS lesions are parenchymal, mainly located in the brainstem, and associated with a graver prognosis than dural sinus thrombi. The presence of clinical clusters indicates that there are at least two pathogenetic pathways in Behçet's syndrome: a reactive arthritis pathway and a thrombophilia pathway. Research into the pathogenesis of Behçet's syndrome has shown that the most consistent genetic marker of Behçet's syndrome is HLA-B51; however, the genetic association of this true-to-form 'complex' disorder with HLA-B51 is only 20%, and a whole-genome study showed associations with 16 different loci. The severity of Behçet's syndrome and the mortality associated with it tend to decrease with time, and there is no associated increase in incidence of atherosclerosis. Although treatment of skin-mucosa manifestations, eye disease and pulmonary artery aneurysms has improved significantly in the past decades, the treatment of CNS lesions and thrombophilia are still problematic.

Abstract
OBJECTIVE To investigate the association of endothelial nitric oxide synthase (NOS), inducible NOS, manganese superoxide dismutase (SOD), and extracellular SOD gene polymorphisms with susceptibility to Behçet disease (BD) in Japan. METHODS Seventy-eight consecutive Japanese patients with BD and 107 healthy control subjects were genotyped by polymerase chain reaction or polymerase chain reaction-restriction fragment length polymorphism methods for endothelial NOS polymorphisms in intron 4, exon 7, and promoter region; inducible NOS polymorphisms in exon 16 and promoter region; manganese SOD Ala16Val polymorphism; and extracellular SOD Arg213Gly polymorphism. HLA-B*51 alleles, which have been found to be associated with BD, were also determined. RESULTS The frequencies of manganese SOD Val16 increased significantly in patients with BD. The manganese SOD-Val/Val genotype and HLA-B*5101 had a synergistic role in controlling susceptibility to BD. There was no significant difference in the frequencies of endothelial NOS, inducible NOS, and extracellular SOD gene polymorphisms between patients with BD and control subjects. CONCLUSION The manganese SOD Val16 allele is associated with the development of BD in Japan. Extracellular SOD, endothelial NOS, and inducible NOS gene polymorphisms do not constitute a risk factor for developing BD in Japan. CLINICAL RELEVANCE The manganese SOD gene polymorphism seems to contribute to BD.

Abstract
Interleukin-8 (IL-8), a CXC chemokine that recruits and activates inflammatory cells, plays a critical role in the pathogenesis of Behcet's disease (BD). To investigate the association of the genetic polymorphism of IL-8 and BD, we genotyped IL-8 -845 T/C, -738 T/A, -353 A/T, -251 A/T, +293 G/T, +678 T/C and receptors CXCR-1 +2607 G/C and CXCR-2 +785 C/T polymorphisms in 119 Korean patients with BD and 119 age- and sex-matched healthy blood donors. Then, single nucleotide polymorphisms (SNPs) and haplotypes were analyzed between patients and controls. There were no SNPs associated with BD. However, the frequency of haplotype TAT inferred from SNPs, IL-8 -353 A/T, -251 A/T and +678 T/C, was significantly higher in patients with BD than controls (5.9 vs 0.0%, P = 0.0001), as was haplotype ATC (6.7 vs 0.0%, P < 0.0001). The haplotype difference was still valid in human leukocyte antigen-B51-negative subjects. In conclusion, we found a significant difference in the distribution of IL-8 gene haplotypes between patients with BD and healthy controls. These results suggest that the genetic polymorphisms of proinflammatory chemokine IL-8 can contribute to the pathogenesis of BD.

Abstract
Behçet's disease (BD) is a systemic inflammatory disorder of unknown etiology, and rarely complicated with myelodysplastic syndrome (MDS). In the present study, we investigated the morphological myelodysplasia and apoptotic rate of bone marrow cells in 15 patients with BD in comparison with MDS patients. Morphological myelodysplasia of bone marrow cells was detected in 53.3% of BD, but none showed chromosomal abnormalities. The apoptotic rate in BD patients (26.1 +/- 8.4%) was significantly higher in normal controls (11.3 +/- 2.4%; p < 0.005) and significantly lower in patients with MDS (50.8 +/- 14.0%; p < 0.0001). These findings suggest that myelodysplasia in patients with BD is more frequent than expected, and possibly due to excess induction of apoptosis of bone marrow cells in BD. However, the rate of apoptotic bone marrow cells is lower than MDS, which may explain the slight peripheral cytopenia in BD, distinct from that in MDS.

Abstract
Behçet's disease is rare in childhood. We describe a 10-year-old boy with neuro-Behçet's disease (NB) who presented with fever, headache, vertigo, and hearing loss. An examination of the cerebrospinal fluid (CSF) revealed pleocytosis as well as elevated protein and interleukin (IL)-6 levels. Brain magnetic resonance imaging (MRI) showed hyperintensity of the right thalamus and midbrain on T2-WI, and gadolinium (Gd) enhancement of left acoustic nerve origin. HLA-B51 was positive. Prednisolone combined with methotrexate resulted in a complete remission. Brain MRI and the CSF IL-6 level were useful for the diagnosis and monitoring of this pediatric patient with NB.

Abstract
BACKGROUND Genetic susceptibility to Behçet's disease (BD) is well documented for HLA-B51 positivity. However, BD is not a simple hereditary disease and it is exaggerated by exogenous stimuli such as microorganisms' infections. Ficolin 2 is a lectin that binds to the surface of microbial cells and kills microbial cells through the activation of complement system. Novel single nucleotide polymorphisms (SNPs) of human Ficolin 2 gene (FCN2 gene) have been recently identified in Caucasian people. OBJECTIVE The aim of the study was to elucidate the contribution of FCN2 gene in the pathogenesis of BD. METHODS The frequencies of genotypes and alleles of FCN2 gene SNPs in the promoter regions (-987, -602, -557, -64, -4) and exon 8 (+6359, +6424) were examined in 83 patients with BD and 64 healthy controls by genotyping with a DNA sequencing method. RESULTS There were no significant differences in genotype and allele frequencies of FCN2 gene SNPs between BD patients and healthy controls. No significant differences in genotype and allele frequencies of FCN2 gene SNPs were detected among different clinical subgroups in BD patients. Significant differences in allele frequencies of FCN gene SNPs at both -557 and -64 sites in the promoter regions were found between HLA-B51 positive groups and HLA-B51 negative groups of BD patients. CONCLUSION The significant differences in allele frequencies of FCN2 gene SNPs in the promoter lesions (-557 and -64 sites) among HLA-B51 positive BD patients may reveal the possibility that ficolin may contribute to the innate immunity of BD among HLA-B51 haplotypes in BD patients.

Abstract
Behçet disease (BD) is a chronic relapsing multisystem disorder of unknown etiology, which preferentially affects the oral and genital mucous membranes, skin, and eyes. Neurological involvement is one of the most serious manifestations of BD, known as neuro-Behçet disease (NBD). We here describe clinical, radiological, and neuropathological findings for two patients with a possible variant of NBD, who manifested progressive ataxia in the absence of mucocutaneo-ocular signs characteristic for BD. Both patients presented a slowly progressive cerebellar phenotype, accompanied by behavioral changes and sphincter disturbance. Brain MRI scan revealed mild atrophy in pons and cerebellum. Both patients showed a mild CSF pleocytosis, and were positive for HLA-B51. The post-mortem examination performed in one patient, showed widespread foci of chronic encephalitis, consistent with the diagnosis of NBD. Steroid pulse therapy was effective in one patient. Identifying the progressive ataxia phenotype of NBD without mucocutaneo-ocular symptoms is important, because these patients may benefit from early steroid therapy.

Abstract
For immunotherapy of residual disease in patients with Philadelphia-positive leukemias, the BCR-ABL fusion regions are attractive disease-specific T-cell targets. We analyzed these regions for the prevalence of cytotoxic T lymphocyte (CTL) epitopes by an advanced reverse immunology procedure. Seventeen novel BCR-ABL fusion peptides were identified to bind efficiently to the human lymphocyte antigen (HLA)-A68, HLA-B51, HLA-B61 or HLA-Cw4 HLA class I molecules. Comprehensive enzymatic digestion analysis showed that 10 out of the 28 HLA class I binding fusion peptides were efficiently excised after their C-terminus by the proteasome, which is an essential requirement for efficient cell surface expression. Therefore, these peptides are prime vaccine candidates. The other peptides either completely lacked C-terminal liberation or were only inefficiently excised by the proteasome, rendering them inappropriate or less suitable for inclusion in a vaccine. CTL raised against the properly processed HLA-B61 epitope AEALQRPVA from the BCR-ABL e1a2 fusion region, expressed in acute lymphoblastic leukemia (ALL), specifically recognized ALL tumor cells, proving cell surface presentation of this epitope, its applicability for immunotherapy and underlining the accuracy of our epitope identification strategy. Our study provides a reliable basis for the selection of optimal peptides to be included in immunotherapeutic BCR-ABL vaccines against leukemia.

Abstract
PURPOSE To describe clinical characteristics of Behçet's disease in Tunisia. METHODS It's a retrospective and multicentric study conducted by the Tunisian society of internal medicine. Inclusion criteria were those of the international study group. Were also included patients without international study group criteria but with at least one manifestation among arthritis, venous thrombosis or neurological manifestation with oral and genital ulceration or oral ulceration and skin lesions. RESULTS Five hundred and nineteen patients were included. 87.5% of them fulfilled the international criteria. The male to female ratio was 2,7. The mean age was 28.7+/-9.3 years at onset and 32.7+/-9.2 years at diagnosis. The incidence of each manifestations was as follows: oral ulcers: 100%, genital ulcers: 87.5%, pseudo-folliculitis: 67.6%, erythema nodosum: 17.5%, positive pathergy test: 51%, joint involvement: 55%, uveitis: 32.2%, vein thrombosis: 24.9%, arterial aneurysms: 3.9%, neurological involvement: 11.6%. The frequency of HLA B51 antigen was 35% among the 187 patients tested. There was no difference in the manifestations of the disease between patients having B51 and those lacking it. Venous thrombosis (29.8 vs 11.4%), arterial involvement (4.4 vs 1.4%) and uveitis (37.5 vs 17,9%) were significantly more frequent in men whereas erythema nodosum (22.9% vs 15.6%) and joint involvement (70,7 vs 49.9%) more frequent in women. The mean follow up was 6,1+/-5.7 years. Mortality rate was 2.3% in our series. CONCLUSION Our study confirms the androtropism of the disease in Mediterranean and Middle east countries. Positive pathergy test and venous thrombosis were more frequent in our study, like those from Mediterranean region. Whereas, ocular and neurological involvement were quite less frequent in our series.

Abstract
BACKGROUND Behçet's disease (BD) is a multisystemic inflammatory disease of unknown origin. Because some researchers have recently suggested a primary association of BD with the A6 allele of the human major histocompatibility complex class I chain-related A (MICA) gene, we investigated microsatellite polymorphisms of the MICA gene in subjects with and without BD. METHODS This was a case-control study of 23 Japanese patients with BD and 23 Japanese volunteers without BD who were compared for MICA microsatellite polymorphisms using the polymerase chain reaction (PCR). We also analysed associations between 5 MICA alleles and the clinical features of patients. RESULTS There was no significant difference between case patients and control subjects in phenotype frequencies. The MICA-A6 allele showed the strongest positive correlation with the human leukocyte antigen allele HLA-B51. Allele A5 showed a strong positive correlation with age at onset and a strong negative correlation with iridocyclitis and HLA-B51. A4 showed a strong negative correlation with ocular lesions and HLA-B51. Patients with the MICA-A6 allele had significantly higher HLA positivity than patients without the allele. INTERPRETATION While the MICA-A6 allele had no significant association with BD, it showed a strong association with HLA-B51. This finding suggests that an association between MICA-A6 and BD may be a secondary phenomenon related to HLA-B51. As several associations with MICA alleles and clinical features have been found, further investigation is expected to elucidate the biological mechanism of action of the MICA protein relative to disease onset.

Abstract
We report a case of possible Behçet's disease (BD) preceded by arthropathy for 5 years. A 29-year-old man experienced right knee swelling and pain since April 1999. Thorough examinations were performed, yet a diagnosis was not established. In December 2004 he experienced recurrent aphtha, following folliculitis-like skin lesions. A human leukocyte antigen examination revealed a positive B51 allele and his illness was diagnosed as possible Behçet disease. Colchicine was administered and his symptoms were ameliorated.

Abstract
MHC class I-restricted CD8+ T cells are important for the generation of protective immune responses in MTB infection. CD8+ CTL (cytotoxic T-lymphocyte)-derived IFN-g may be especially important both for cells lacking MHC class II molecules, e.g. in the lung and for macrophages where mycobacteria can evade recognition during chronic infection by sequestering their antigens away from sensitized CD4+ T cells. This study was designed to detect any association of MHC class I (HLA-B) molecules with pulmonary tuberculosis. A total of 75 individuals, comprising of 33 patients with pulmonary tuberculosis; 12 HIV patients who developed tuberculosis and 30 healthy controls, were included in the study. They were typed for HLA-B by the PCR-SSP method. The results of only HLA-B alleles, which are highly significant, are presented here. The number of healthy individuals with HLA-B52 was significantly high when compared to the patient groups (healthy versus TB: 21.2% versus 0.0%, OR=0.0, P<0.0001, P(c)=0.003; healthy versus HIV-TB: 21.2% versus 16.7%; OR=0.74; P<0.001; P(c)=0.003). In contrast, the number of patients, both TB- and HIV-TB-positive, with HLA-B51 was significantly high when compared to the healthy group of individuals (TB versus healthy: 36.7% versus 3%; OR=18.53; P<0.0001; P(c)=0.001; HIV-TB versus healthy: 41.7% versus 3%; OR=22.86; P<0.0001; P(c)=0.001). Only one healthy control was positive to HLA-B51; however this individual also had HLA-B52. The results of this study suggest that HLA-B52(5) has a negative, i.e. a protective association and HLA-B51(5) has a positive (susceptible) association, for pulmonary tuberculosis. Studies on HLA-B51 and HLA-B52 in a larger population to assess their role in tuberculosis may be useful for TB-vaccination strategies, since HLA profiles are likely to be related to vaccine efficacy.

Abstract
Adamantiades-Behcet's disease (ABD) is a chronic inflammatory multisystem disorder. Although the precise etiology is unclear, high prevalence of human leukocyte antigen (HLA)-B51 predisposition and predominantly involved T-helper type 1 cells (Th1)-type proinflammatory cytokines and extrinsic Streptococcal infection suggest a substantial association with an immunogenetic basis and strengthens the hypothesis that IL-12, a potent inducer of Th-1 immune reaction, is a putative candidate in its pathogenesis. These clinicopathological findings led us to examine interleukin 12 p40 (IL-12B) promoter polymorphism, for which the 4-base pair (bp) heterozygous insertion has been shown to affect the gene transcription and subsequent protein production. We analyzed IL-12B promoter genotypes in 194 Japanese subjects (92 with ABD and 102 normal controls) by PCR-based restriction enzyme digestion. The frequency of the insertion heterozygosity was significantly higher in patients than in controls (49/92, 53.3% vs 39/102, 38.2%, respectively). Comparing these with HLA haplotype data, this trend was more significant in HLA-B51-negative patients (29/42, 69.0% vs 20/50, 40.0%; P = 0.005). As assessed by semiquantitative reverse transcription-PCR and ELISA, stimulation with Streptococcal antigens specifically increased expression of IL-12 p40 mRNA and protein, in conjunction with IL-12 p70 induction, in peripheral blood mononuclear cells from heterozygous patients. Our results provide evidence for anti-bacterial host response toward Th1-immunity mediated by IL-12 in patients with ABD, and the possible insight into the genetic susceptibility that is independent of HLA background.

Abstract
Human leukocyte antigen (HLA) has been associated with Behcet's disease (BD), among which HLA-B51 is the most strongly associated genetic marker. The sandwich hybridization technique was applied in the design of the specific oligonucleotide probes to ensure the specific and accurate results. The probe-spotted chip was hybridized with the polymerase chain reaction (PCR) amplicons including nine suballeles (B*5101-B*5109) of exons 2 and 3 of HLA-B51 gene to determine the HLA-B51 genotypes. The results were subsequently confirmed by (PCR-SSP) and sequencing and were identical to those from polymerase chain reaction-sequencing specific primers (PCR-SSP) in 27 patients with BD and 30 healthy controls. This suggests that we successfully developed the oligochip for Behcet's-associated gene HLA-B51, which can effectively and accurately identify the HLA-B51 genotypes.

Abstract
A 77-year-old man was diagnosed as having essential thrombocythemia in 1992. Treatment with hydroxyurea was started in 1997, which stabilized the platelet count. The patient then suffered from pharyngalgia and rhinitis with a high fever, immediately after which he developed tarry stools and anemia and was admitted to our hospital. The physical examination revealed splenomegaly, oral aphthous ulcers, genital ulcers and skin lesions on the lower limbs. His hematological and biochemical tests revealed anemia and increased level of C-reactive protein. He also had an HLA-B51 phenotype. The findings of gastro-intestinal and colon fiberoscopy showed a duodenal ulcer and multiple ulcers on ascending colon. He was thus diagnosed as having intestinal tract-type Behçet disease. After withdrawal of the hydroxyurea administration, the intestinal ulcers, oral aphthous ulcers and genital ulcers improved.

Abstract
BACKGROUND Behçet's disease (BD) is a chronic multi-system inflammatory disorder of unknown aetiology, which shares many features of the inflammatory bowel diseases (IBDs). CARD15 has recently been identified as the first susceptibility gene in Crohn's disease (CD). OBJECTIVE Given certain clinical and pathological similarities between CD and BD, and recent evidence of linkage of BD to the CARD15 genomic region, the aim of this study was to investigate the role of CARD15 variants in determining susceptibility to BD. METHODS We studied 374 BD patients from three ethnically homogeneous cohorts (white English, Turkish, and Middle Eastern Arabs of Palestinian and Jordanian descent). Mutation detection of CARD15 was performed by direct sequencing in a subset of patients from each group and the identified variants were genotyped in the complete cohorts. Case-control analyses were carried out with additional stratification by the BD-associated allele, HLA-B*51. RESULTS Mutation detection identified six previously described CARD15 polymorphisms at a frequency of > 3%. Additionally, two of the three CD-associated polymorphisms were present, but at low frequency. The frequency of haplotypes, constructed from nine genotyped polymorphisms, demonstrated significant variation between different ethnic groups. However, case-control analyses demonstrated no association between the CARD15 polymorphisms and susceptibility to BD, irrespective of HLA-B*51 status. CONCLUSION CARD15 variant alleles are not associated with susceptibility to BD. Other shared loci, currently under investigation, may determine susceptibility to both CD and BD.

Abstract
UNLABELLED This study was carried out to determine the characteristics and incidence of hearing loss and vestibular disturbance in Behcet's syndrome with a large number of patients. Sixty-two patients with Behcet's syndrome were included in this study, 34 men and 28 women whose mean age was 33.7 (15-60). Sixty-two healthy normal control subjects (38 male and 24 female) were included. Patient and control groups were questioned about any history of audio-vestibular disturbance and underwent physical and ENT examination and the following audiologic tests: pure tone audiometric test (0.25, 0.5, 1, 2, 4, and 6 kHz), tympanogram, speech discrimination, short increment sensitivity index, tone-decay test, auditory brainstem response. Vestibular system was evaluated by videonistagmogram and caloric test. Cranial and brainstem magnetic resonance imagine (MRI) of patients who have vestibular disturbances were practiced to examine the central nervous system. Both the patient and the control groups were tested with the HLA-B51 antigen. Pure tone audiogram showed sensory-neural hearing loss (25 dB hearing level in at least two frequencies) in 20 of the 62 (32%) Behcet's patients while the control group were normal. There was a hearing loss involving high frequencies in the audiograms of Behcet's patients with hearing disturbances. The recruitment investigation tests and auditory brain stem response confirmed cochlear involvement in all 20 patients. Caloric stimulation tests revealed a normal vestibular function in all patient and control group. In electronystagmography, 21 (34%) patients had hypometric or hypermetric saccades and smooth pursuit tests showing that 4 (6%) patients had pathological changes while the control group was normal. HLA-B51 antigen was found positive in 15 of 20 Behcet's patient with hearing loss. CONCLUSION (1) The hearing and vestibular disturbances in Behcet's syndrome is more prevalent than previously recognized; (2) Hearing loss in high frequencies in Behcet's patients is an indicator of cochlear involvement in this disease; (3) There is a higher prevalence of central vestibular syndrome in Behcet's patients than it was thought before; (4) HLA-B51 antigen may be able to be a prognostic factor for sensorineural hearing loss in Behcet's patients.

Abstract
To determine the prevalence, clinical and radiological characteristics of spondyloarthropathy (SpA) in patients with inflammatory bowel disease (IBD), to assess the association between HLA B27 and B51 and the extraintestinal symptoms and to evaluate whether IBD is associated with Behçet's disease (BD). One hundred and sixty-two consecutive adult patients with established diagnosis of IBD as either Crohn's disease (CD) or ulcerative colitis (UC) were evaluated. All the patients including those previously diagnosed with or without SpA had a complete rheumatologic examination and they were evaluated according to the European Spondyloarthropathy Study Group (ESSG) criteria for SpA and The International Study Group for Behçet's disease criteria for BD. The demographic and clinical data were recorded on a standardized form. The radiographies were obtained in all the patients and computed tomography (CT) was performed in the patients with suspected pelvic radiographies and/or low back pain in the physical examination. Radiological evaluation was made according to the Modified New York criteria. HLA B27, B51 and anti-neutrophile cytoplasmic antigen (ANCA) were searched in all the patients. Of the 162 patients with IBD (mean age 41.48+/-11.63 years, male 60, female 102), 78 were CD and 84 were UC. The mean of the IBD duration was 54.92+/-50.32 months and SpA duration was 20.63+/-34.37 months. The prevalence of SpA and AS in IBD was 45.7 and 9.9%, respectively. Frequencies of SpA and AS, the difference between UC and CD were not significant. Spondylitis, enthesitis, peripheral arthritis, oral ulcer and uveitis were not different between UC and CD, but erythema nodosum was found significantly more common in the CD patients compared with UC patients (P=0.005). The duration of IBD and SpA was similar in both groups. As the IBD duration increased, the prevalence of SpA development decreased (rr=0.991, P=0.009). Of the IBD patients, 13.6% were asymptomatic for musculoskeletal manifestations of SpA and their sacroiliac radiographies and CTs showed grade 2 sacroiliitis. HLA B27, B51 and ANCA positivities were not different between the patients with UC and CD. HLA B27 was significantly more common in the patients with sacroiliitis, spondylitis, enthesitis, peripheral arthritis, erythema nodosum, uveitis (P<0.001) and oral ulcer (P=0.025). BD was diagnosed in none of the patients. ANCA positivity was found to be related with the presence of erythema nodosum and uveitis (P=0.001 and P=0.005). The prevalence of SpA and AS is higher in the prospectively evaluated patients with radiological studies than those in the previously published studies. There is a high prevalence of asymptomatic sacroiliitis in IBD. An early diagnosis of inflammatory arthritis in IBD patients may prevent a disability due to SpA and AS.

Abstract
OBJECTIVE This study evaluates the presence of serum soluble CD28 (sCD28) in Behçet's disease (BD) and its relationship with clinical manifestations. METHODS Soluble CD28 concentration was determined by ELISA in 120 patients with BD (80 patients in active stage), 60 patients with rheumatoid arthritis (RA) and 60 healthy subjects. RESULTS Concentrations of sCD28 were significantly higher in patients with BD and RA than in healthy subjects. Patients with active BD expressed the highest level of sCD28 in serum. Soluble CD28 exhibited a drastic increase in active BD patients, compared to BD in remission. Soluble CD28 concentrations were higher in patients with active BD patients having vasculitis. Significant positive correlation was observed in a longitudinal study of 15 BD patients, between sCD28 and C-reactive protein. CONCLUSION Our study suggests that fluctuations of sCD28 in BD reflects disease activity and should be assessed in evaluating disease activity.
