RESUMO
OBJECTIVES: This study aimed to develop clinical guidelines for the management of vascular Behçet's disease (BD) by the Behçet's Disease Research Committee of the Ministry of Health, Labour and Welfare of the Japanese Government. METHODS: A task force proposed clinical questions (CQs) concerning vascular BD based on a literature search. After screening, draft recommendations were developed for each CQ and brushed up in three blinded Delphi rounds, leading to the final recommendations. RESULTS: This study provides recommendations for 17 CQs concerning diagnosis and differential diagnoses, assessment of disease activity, and treatment. The guidelines recommend immunosuppressive treatments, for both arterial and venous involvement with active inflammation. Anticoagulation is also recommended for deep vein thrombosis except in high-risk patients. Surgical and endovascular therapies can be optional, particularly in patients with urgent arterial lesions undergoing immunosuppression. In addition, two sets of algorithms for diagnosis and treatment are shown for arterial and venous involvement. CONCLUSIONS: These recommendations are expected to serve as useful tools in the daily clinical practice of BD.

PURPOSE OF REVIEW: To discuss clinical and pathogenic roles of HLA-B∗51 in Behçet's syndrome. RECENT FINDINGS: HLA-B∗51 remains the most important genetic factor in Behçet's syndrome, despite the recent identification of several susceptibility genes. The prevalence of HLA-B∗51 has been shown to differ among phenotype-based clinical clusters in the same patient population. HLA-B∗51 shows epistatic interaction with the susceptible allele of endoplasmic reticulum aminopeptidase (ERAP)1 encoding the Hap10 allotype, which has the lowest trimming activity of the MHC-Class I binding peptides. Subsequent molecular studies have suggested that the disease-associated Hap10 allotype is implicated in the generation and selection of the disease protective or promoting peptides loading onto HLA-B∗51, although these pathogenic peptides have yet to be identified. SUMMARY: HLA-B∗51 is a hallmark of Behçet's syndrome but genetic markers are not very useful in the diagnosis of Behçet's syndrome. Rather, it is considered an important factor in determining clinical phenotypes in this heterogeneous condition. The epigenetic interaction of HLA-B∗51 with ERAP1 sheds light on pathogenesis.

BACKGROUND: The small-molecule phosphodiesterase 4 inhibitor apremilast modulates cytokines that are up-regulated in Behçet's syndrome. In a phase 2 trial involving patients with Behçet's syndrome, apremilast reduced the incidence and severity of oral ulcers. Data on the efficacy and safety of apremilast in patients with Behçet's syndrome who had active oral ulcers and had not previously received biologic agents are limited. METHODS: In a phase 3 trial, we randomly assigned, in a 1:1 ratio, patients who had Behçet's syndrome with active oral ulcers but no major organ involvement to receive either apremilast at a dose of 30 mg or placebo, administered orally, twice daily for 12 weeks, followed by a 52-week extension phase. The primary end point was the area under the curve (AUC) for the total number of oral ulcers during the 12-week placebo-controlled period (with lower values indicating fewer ulcers). There were 13 secondary end points, including complete response of oral ulcers, change from baseline in pain associated with oral ulcers, disease activity, and change from baseline in the Behçet's Disease Quality of Life score (range, 0 to 30, with higher scores indicating greater impairment in quality of life). Safety was also assessed. RESULTS: A total of 207 patients underwent randomization (104 patients to the apremilast group and 103 to the placebo group). The AUC for the number of oral ulcers was 129.5 for apremilast, as compared with 222.1 for placebo (least-squares mean difference, -92.6; 95% confidence interval [CI], -130.6 to -54.6; P<0.001). The change from baseline in the Behçet's Disease Quality of Life score was -4.3 points in the apremilast group, as compared with -1.2 points in the placebo group (least-squares mean difference, -3.1 points; 95% CI, -4.9 to -1.3). Adverse events with apremilast included diarrhea, nausea, and headache. CONCLUSIONS: In patients with oral ulcers associated with Behçet's syndrome, apremilast resulted in a greater reduction in the number of oral ulcers than placebo but was associated with adverse events, including diarrhea, nausea, and headache.

OBJECTIVES: No large-scale registration study has comprehensively evaluated the activities of daily living (ADL) in patients with Behçet's disease. METHODS: The Japanese government provided us with a dataset of confirmed or suspected Behçet's disease cases derived from ongoing national registration. ADL were categorized and analysed into four categories in patients who satisfied the International Criteria for Behçet's Disease. RESULTS: Data from 2960 patients (men 38.9%, women 61.1%; median age 39 years) were assessed. While 1767 patients (59.7%) had normal ADL, the others had impaired ADL comprising limited but not assisted [n = 1058 (35.7%)], partially assisted [n = 116 (3.9%)] and fully assisted [n = 19 (0.6%)]. Logistic regression analysis showed that chronic ocular lesions [odds ratio (OR) 1.85 (95% CI 1.46, 2.35), P < 0.001], paralysis [OR 2.51 (95% CI 1.58, 3.97), P < 0.001], psychosis [OR 3.16 (95% CI 2.02, 4.95), P < 0.001] and arthritis [OR 1.69 (95% CI 1.44, 1.99), P < 0.001] led to the risk of impaired ADL. Chronic ocular lesions [OR 3.61 (95% CI 2.27, 5.72), P < 0.001], paralysis [OR 3.43 (95% CI 1.87, 6.30), P < 0.001] and psychosis [OR 3.60 (95% CI 2.00, 6.50), P < 0.001] were related to the requirement of physical assistance (partially or fully assisted), although arthritis [OR 1.39 (95% CI 0.93, 2.06), P = 0.108] was not a significant factor in this model. CONCLUSION: Ocular lesions, neurological manifestations and arthritis affected ADL. Patients with ocular lesions or neurological manifestations more frequently required physical assistance.

OBJECTIVES: The management of elderly-onset rheumatoid arthritis (EORA) is challenging due to progressive functional disability, increased comorbidities, and high drug-related risks. EORA is defined as disease onset after 60 years since 1985. We assessed whether this cut-off age was optimal in a progressively ageing society. METHODS: This study used two cohorts of consecutive rheumatoid arthritis (RA) patients: the Nippon Medical School (NMS) cohort (n = 204) and the Keio cohort (n = 296). Clinical findings independently correlated with the age of RA onset were selected as 'EORA features' from previously reported EORA characteristics using univariable and multivariable regression analyses. Receiver operating characteristic curve analysis was conducted to determine the cut-off age that best selected patients with all EORA features. RESULTS: Acute onset, negative anti-cyclic citrullinated peptide antibody, and high erythrocyte sedimentation rate were selected as 'EORA features' in both cohorts. Patients with all EORA features were more numerous with age and almost exclusively older than 65 years. The optimal EORA cut-off age was 73 years with an area under the curve (AUC) of 0.82 in the NMS cohort and 68 with an AUC of 0.93 in the Keio cohort. In the NMS cohort, Health Assessment Questionnaire-Disability Index and comorbidities in patients with disease onset between 60 years and the projected cut-off age were similar to those in younger-onset RA, but differed from those in patients with disease onset older than the projected cut-off age. CONCLUSION: The optimal EORA cut-off age was greater than the conventional definition, but this needs to be validated in different patient populations.

OBJECTIVES: Apremilast efficacy and safety was assessed in a prespecified subgroup of Japanese patients with oral ulcers associated with Behçet's syndrome from a Phase 3 randomized, placebo-controlled, double-blind study of apremilast (RELIEF). METHODS: The primary end point was area under the curve for number of oral ulcers during the 12-week placebo-controlled phase (AUCWk0-12). Key secondary end points were change from baseline in oral ulcer pain, complete oral ulcer resolution, and measures of disease activity and quality of life (QoL). RESULTS: Thirty-nine Japanese patients were randomised (apremilast 30 mg BID: n = 19; placebo: n = 20). Improvements at Week 12 were observed for apremilast vs. placebo in AUCWk0-12 for the number of oral ulcers (115.9 vs. 253.3; nominal P = 0.0168); 57.9% vs. 25.0% achieved complete oral ulcer resolution, 47.4% vs. 0.0% achieved oral ulcer resolution by Week 6 and maintained oral ulcer-free status for ≥6 additional weeks; mean change from baseline in BSAS was -10.5 vs. 0.5. Favourable effects were observed for apremilast vs. placebo in other secondary end points, including QoL. Clinical benefits were sustained over 28 weeks of continued apremilast treatment. Adverse events were consistent with apremilast's known safety profile. CONCLUSIONS: Apremilast reduced the number of oral ulcers and overall disease activity in this Japanese subgroup with Behçet's syndrome.

OBJECTIVES: Approximately 30-60% of Behçet's disease patients exhibit joint symptoms. The aim of this study was to determine the clinical characteristics of such patients in Japan. METHODS: This study retrospectively analyzed 151 Behçet's disease patients with joint symptoms who had been treated at seven cooperative medical institutions from 2007 to 2017. We investigated their clinical characteristics and treatments. RESULTS: The most commonly affected joints were the knee, ankle, and proximal interphalangeal joints. Of the cases with pain and swelling, 18 of 293 joints (11 cases) displayed narrowing of the cleft or deformity by X-ray analysis. Improvement in their arthritis was observed in 80% of the patients who received steroids as initial treatment; however, the rate of improvement was lower in patients who had received prednisolone (PSL) at <10 mg/day. The recurrence of joint symptoms was significantly less common in the colchicine group than in the PSL group. CONCLUSIONS: These results suggest that PSL is effective for remission induction for the treatment of joint symptoms of Behçet's disease. Additionally, colchicine is effective in preventing the recurrence of joint symptoms in Behçet's disease. Furthermore, joint damages like joint space narrowing or with any deformity can often be observed in Behçet's disease.

OBJECTIVES: This study aimed to determine the clinical efficacy of apremilast for oral ulcers (OUs), extra-oral manifestations, and overall disease activity in patients with Behçet's disease (BD). METHODS: A systematic literature search was performed in PubMed, Embase, Cochrane Library, and Web of Science Core Collection. Studies assessing the treatment effects of apremilast in BD were included. The odds ratios (ORs) of being symptom-free for individual manifestations and mean difference (MD) of Behçet's Disease Current Activity Form (BDCAF) scores were calculated with 95% confidence intervals (CIs) at 12 and 24 weeks using a random-model meta-analysis. RESULTS: Of 259 screened articles, eight were included. After 12 weeks of apremilast treatment the OR of symptom-free was as followings: OUs, 45.76 (95% CI, 13.23-158.31); genital ulcers, 4.56 (95% CI, 2.47-8.44); erythema nodosum, 3.59 (95% CI, 1.11-11.61); pseudofolliculitis, 2.81 (95% CI, 1.29-6.15); and arthritis, 3.55 (95% CI, 1.71-7.40). Furthermore, BDCAF scores at 12 weeks were significantly reduced (MD=-1.38; -1.78 to -0.99). However, the proportion of oral-ulcer-free patients increased at 24 weeks (OR = 14.88; 4.81 to 46.07). CONCLUSIONS: The currently accumulated data indicate an improvement in mucocutaneous and articular symptoms by short-term apremilast treatment in patients with BD.

OBJECTIVES: This study assessed the efficacy and safety of apremilast for the oral ulcers associated with Behçet's syndrome (BS) up to 64 weeks. METHODS: The phase 3, double-blind, placebo-controlled RELIEF study randomised adult patients with active BS to placebo or apremilast 30 mg twice daily for 12 weeks, followed by an extension phase with all patients receiving apremilast through Week 64 and 4-week post-treatment follow-up (upon treatment discontinuation). The primary endpoint was area under the curve for the number of oral ulcers over 12 weeks (AUCWk0-12), reflecting the number of oral ulcers over time and accounting for their recurring-remitting course. Oral ulcer number, complete and partial responses, pain and disease activity and quality of life (QoL) were also assessed throughout the study. RESULTS: A total of 207 participants were randomised and received at least one dose of study medication; 178 entered the extension phase and 143 completed Week 64. AUCWk0-12 was significantly lower with apremilast versus placebo (p<0.0001), and oral ulcers number, pain, complete/partial responses, disease activity and QoL with apremilast versus placebo showed improvements at Week 12, which were maintained through Week 64. The most common adverse events were diarrhoea, nausea, headache and upper respiratory tract infection; no new safety concerns were observed with longer-term apremilast exposure. CONCLUSIONS: In patients with oral ulcers associated with BS, apremilast was efficacious and benefits were sustained up to 64 weeks with continued treatment. Apremilast was well tolerated, and safety was consistent with its known safety profile.

OBJECTIVE: To determine the real-world short-term efficacy and safety of apremilast for Behçet's disease (BD). METHODS: The study included patients who received apremilast for refractory oral ulcers in addition to meeting International Study Group criteria for BD or the revised International Criteria for Behçet's Disease. To assess the efficacy of apremilast, Behçet's disease current activity form (BDCAF) and patients' self-perception of their disease activity were monitored for three months. The disease phenotypes, laboratory data, concomitant medication use, and adverse events were also investigated. RESULTS: Fourteen BD patients were included in the study. Concomitant drug use were as follows: colchicine 92.9%, prednisolone 21.4%, immunosuppressants 28.6%, and tumor-necrosis inhibitor 14.3%. Oral ulcers and BDCAF scores at 3 months showed significant improvement compared to baseline. Adverse events during the study were diarrhea (n = 3, 21.4%), nausea (n = 3, 21.4%), music hallucination (n = 1, 7.1%), and branch retinal vein occlusion (n = 1, 7.1%). Apremilast was discontinued in 1 patient (7.1%) due to nausea. CONCLUSION: Significant improvement in oral ulcer and BDCAF with apremilast was confirmed in real-world BD patients after 3 months. The combination of colchicine and apremilast appears to be well tolerated in BD in the short-term.

BACKGROUND: How HLA-A26 modulates Behçet's disease (BD) ocular lesions such as iridocyclitis and retinochorioiditis has not been scrutinized. METHODS: Ministry of Health, Labour and Welfare of Japan provided us a database of BD patients who were registered from 2003 to 2014. We selected patients who satisfied International Criteria for BD and whose data for HLA-A26 was available. RESULTS: Eligible 557 patients consisting of 238 men (42.7%) and 319 women (57.3%), whose median age was 38 years old (interquartile range 29-47) were analyzed. Prevalence of general ocular lesions, iridocyclitis, retinochorioiditis, and chronic lesions were 43.1%, 30.7%, 34.1%, and 17.4%, respectively. The prevalence of ocular lesions was higher among HLA-A26 carriers compared to that among HLA-A26 non-carriers with odds ratio (OR) of 2.5 (95% confidence interval (95% CI) 1.8-3.5, p < .001) for general ocular lesions, OR of 2.5 (95% CI 1.7-3.6, p < .001) for iridocyclitis, OR of 2.8 (95% CI 1.9-4.0, p < .001) for retinochorioiditis, and OR of 2.7 (95% CI 1.7-4.3, p < .001) for 'chronic ocular lesion following iridocyclitis or retinochorioiditis'. The HLA-A26 had a similar impact on ocular lesions between HLA-B51 positive and negative cases (Breslow-Day test, p > .05). However, the HLA-A26 had a larger impact on iridocyclitis for men compared to women (Breslow-Day test, p = .040). The male HLA-A26 carriers had higher risk of iridocyclitis with OR of 3.4 (95% CI 2.0-5.9, p < .001), while the OR for women was 1.5 (95% CI 0.9-2.6, p = .146). CONCLUSION: HLA-A26 carriers had higher risk for iridocyclitis and retinochorioiditis. However, the impact was more prominent for men.

Behçet's disease is a chronic relapsing inflammatory disorder characterized by oral and genital ulcers, skin lesions, and uveitis. Although the involvement of the gastrointestinal, large vascular, and central nervous systems is less common, it can be fatal at times. To suppress inflammatory exacerbations and recurrences which can cause irreversible organ damage, treatment should be individualized according to the disease phenotype and severity. Apremilast, an oral phosphodiesterase 4 inhibitor, is used to treat psoriasis. The enzyme specific inhibitor increases intracellular cAMP levels, which modulate multiple signaling pathways in both innate and adaptive immunocompetent cells, leading to attenuation of inflammatory responses through the suppression of the functions of various types of immunocompetent cells including Th1 cells, Th17 cells and M1 macrophages. Current evidence shows that apremilast is effective for oral ulcer, the most common symptom of Behçet's disease. An oral ulcer is considered to represent the basic immunopathology of Behçet's disease, because the disease susceptibility genes are shared between Behçet's disease and recurrent aphthous stomatitis. The favorable effects have been documented in other inflammatory diseases with symptoms similar to those of Behçet's disease. The further studies would shed the light on the potential of apremilast for the treatment of Behçet's disease.

Objectives: Although intensive immunosuppressive treatment is necessary for the severe cases with polymyositis (PM)/dermatomyositis (DM), the prognostic factors or disease activity indices for PM/DM have not been established. Here we investigated the association between serum microRNA-1 (miR-1) level and clinical course of patients with PM/DM.Methods: We retrospectively reviewed baseline clinical and laboratory findings, treatment regimens and outcomes in patients with PM/DM. The serum samples were collected from PM/DM patients and healthy controls (HC). Serum miR-1 levels were determined by quantitative real-time PCR.Results: Twenty-two patients were recruited. The average serum miR-1 level was significantly higher in the PM/DM as compared to HC (p = .0085) and was decreased by treatment (p = .032). We divided the PM/DM-ILD patients into two groups, high and normal miR-1 groups. Although there were no significant differences in the clinical data and the initial prednisolone (PSL) dose between the two groups, PSL dose at 16 weeks, cumulative PSL dose until 16 weeks, and frequency of serious infections were significantly higher in the high miR-1 group as compared to the normal group (p = .025, .036, and .026, respectively).Conclusion: We propose serum miR-1 as a promising novel biomarker for predicting therapeutic response in PM/DM-ILD.

Objectives: To scrutinize the influence of HLA-B51 to each clinical manifestation of patients with Behçet's disease (BD) using a database of the Ministry of Health, Labour and Welfare of Japan.Methods: The database of newly registered patients with BD was obtained from the Japanese Ministry of Health, Labour and Welfare. Patients who met International Criteria for Behçet's Disease (ICBD) and had data for HLA-B51 were selected and analyzed.Results: Among the 3044 analyzable cases, 1334 (43.8%) were men and 1710 (56.2%) were women; the median age was 38 years (IQR 29-48). HLA-B51 was positive for 1334 (44.5%). Prevalence of selected manifestations was 98.5% for oral ulceration, 85.5% for skin lesion, 42.1% for ocular lesion, 69.1% for genital ulceration, and 29.0% for gastrointestinal symptom. HLA-B51-positive patients had higher risk for ocular lesion (OR 1.59, 95%CI: 1.37-1.84; p < .001) and lower risk for genital ulceration (OR 0.72, 95%CI: 0.62-0.84; p < .001) and gastrointestinal symptom (OR 0.65, 95%CI: 0.55-0.77; p < .001). No significant difference was observed for other organ involvement; oral ulceration, skin lesion, positive pathergy test, arthritis, epididymitis, vascular lesion, or neurological manifestation. Subgroup analyses revealed that HLA-B51 was not related to genital ulceration in the cases with an ICBD score of 6 or higher and that HLA-B51 tended to more largely affect the risk of three manifestations for men compared to that for women.Conclusion: HLA-B51 positive is a risk factor for ocular lesion and vice versa for genital ulceration and gastrointestinal symptoms in patients with Japanese BD.

PURPOSE OF THE REVIEW: We clarify clinical characteristics of patients with immune checkpoint inhibitor (ICI)-induced myositis. RECENT FINDINGS: In 13 of 15 cases with ICI-induced myositis, the type of malignancy was melanoma. Eight, 4, and 3 patients received anti-PD-1 alone, anti-CTLA4 alone, and a combination of those, respectively. The mean period to the onset of ICI-induced myositis from the initiation of ICI was 4 weeks. Myocarditis was a complication in five patients. Seven of the patients died. The causes of death were myocarditis in three patients, respiratory muscle paralysis in two patients, and cancer progression in two patients. In patients without myocarditis or respiratory muscle paralysis, the prognosis for myositis was favorable with normalization of the CK levels occurring upon the cessation of ICI and the administration of immunosuppressive agents. Myocarditis and respiratory muscle paralysis are the major causes of death as immune-related adverse events in patients with ICI-induced myositis.

OBJECTIVES: This study aimed to identify patients with high-probability of ocular involvement of Behçet's disease (BD). METHODS: The Japanese Ministry of Health, Labour and Welfare provided dataset of ongoing nationwide BD registration project. A patient who had confirmed BD and who was suspected to have BD was registered. We mainly analyzed newly registered patients who had the data for all demographic and diagnostic parameters regardless of fulfilment of any diagnostic criteria. RESULTS: Among 3213 patients with confirmed or possible BD, 1382 (43.0%) were men and 1831 (57.0%) were women with a median age of 38 years (interquartile range (IQR) 30-49 years). The median duration between onset and registration was 0 year (IQR 0-3). A binomial multivariable logistic regression analysis revealed that being female (odds ratio (OR) 0.63, 95% confidence interval (CI) 0.53-0.75, p < .001), duration since onset (OR 1.33 per 10 years, 95% CI 1.18-1.51, p < .001), genital ulceration (OR 0.28, 95% CI 0.23-0.34, p < .001), and gastrointestinal symptoms (OR 0.36, 95% CI 0.30-0.44, p < .001) were related to the ocular lesion. Analyses based on data of 2800 patients who satisfied International criteria of BD, age-, sex-, duration-based subgroup analyses, analyses targeting iridocyclitis and retino-uveitis, and analysis including patients with missing data confirmed that the four factors were associated with the probability of eye involvement. CONCLUSION: The ocular involvement did not accompany with genital ulcer or gastrointestinal symptoms at the early stage of BD.

Background: Clinical data of patients with entro-, vasculo-, and neuro-variant possible Behçet's disease (BD) based on Japanese criteria has not yet comprehensively reported. Methods: This ongoing nation-wide registration has been carried out by the Japanese Ministry of Health, Labour and Welfare. The Ministry asked physicians who diagnosed a patient with confirmed or possible BD to register the patient data by filling out a registration form. The Ministry provided us with the dataset after unlinkable anonymization. We analyzed 2003-2014 database generated from the early stage new cases. Results: Among the 7950 analyzable cases, 694 (8.7%) had variant-type possible BD without satisfying complete/incomplete criteria. Of the 694 patients, 479, 46, and 169 had entero-, vasculo-, and neuro-variant possible BD, respectively. Out of these 694 patients, 35 (5.0%) and 154 (22.2%) satisfied the International Study Group criteria and the International Criteria of BD, respectively. Entero-variant possible patients rarely (1.8%) had ocular lesions. Patients with vasculo-variant possible BD were featured by low genital ulceration risk (6.8%) and frequent positive HLA-B51 (60.0%). Neuro-variant possible BD was featured by high median age at registration (48 year). Vasculo- (69.6%) and neuro-variant (68.6%) BD patients showed clear male dominance. Epididymitis was very rare among variant-type possible BD men. Conclusion: We analyzed 694 early-stage variant-type possible BD cases. We believe the data from our study will contribute to further international discussion regarding BD diagnostic criteria and clarification of the clinical presentations of the Japanese variant-type possible BD patients.

OBJECTIVES: TRIM21 is an E3 ubiquitin ligase for interferon regulatory factors (IRFs) that are involved in innate and acquired immunity. Here, we evaluated the role of TRIM21 in the interferon (IFN) signature of systemic lupus erythematosus (SLE). METHODS: Twenty SLE patients and 24 healthy controls were enrolled in this study. We analyzed mRNA expression of TRIM21, type I IFN, and IFN-inducible genes in peripheral blood mononuclear cell (PBMC). The protein levels of IRFs were assessed by Western blotting in PBMCs cultured with or without MG-132. RESULTS: The expression of TRIM21 mRNA and protein was significantly higher in SLE PBMCs as compared to healthy controls. There was a correlation between TRIM21 mRNA expression and SLE activities. In contrast to a negative correlation between mRNA expression level of TRIM21 and those of type I IFNs in healthy controls, we found a positive correlation between them in anti-TRIM21 antibody-positive SLE patients. Neither positive nor negative correlation was observed in the autoantibody-negative SLE patients. Western-blotting analysis revealed impaired ubiquitin-dependent proteasomal degradation of IRFs in SLE PBMCs. CONCLUSION: Our study showed ubiquitin-dependent proteasomal degradation of IRFs was impaired in anti-TRIM21 antibody-dependent and -independent fashions, leading to amplification of IFN signature in SLE.

Objective: This report aimed to scrutinize the prevalence of Behçet's disease (BD)-related clinical manifestations based on age- and sex-specific subgroups using a Japanese nationwide registration database. Methods: The database of newly registered BD was obtained from the Japanese Ministry of Health, Labour and Welfare. Patients who met the International Criteria for Behçet's Disease were selected and analysed. Results: Among 6627 International Criteria for Behçet's Disease cases, 2651 (40.0%) were men and 3976 (60.0%) were women with a median age of 39 years (interquartile range: 31-50 years). Ocular lesion was more common in male [odds ratio (male: female) 2.64 (95% CI: 2.35, 2.95, P < 0.001)] and genital ulceration was more common in female (odds ratio = 0.29, 95% CI: 0.25, 0.32, P < 0.001). Ocular lesion (P < 0.001), arthritis (P < 0.001) and vascular lesions (P < 0.001) were more frequently observed in elderly registered patients. Contrarily, genital ulceration (P < 0.001), epididymitis of males (P = 0.023) and oral ulceration (P = 0.003) were more common in younger patients. Simultaneous assessment of sex and age revealed that male predominance of ocular involvement was found in the young adult generation, but not in patients over 70 year of age. A female predominance of genital ulcer was prominently observed in patients 20-59 year of age; however, the sex difference was not found in patients over 60 years of age. Sensitivity analysis using International Study Group criteria replicated the results. Conclusion: We showed that clinical phenotype in early phase of BD was different depending on onset age and sex.

OBJECTIVES: To investigate whether on-demand ultrasonography (US) assessment alongside a routine examination is useful in the management of rheumatoid arthritis (RA). METHODS: US was performed in eight (bilateral MCP 2, 3, wrist and knee) joints as the routine in a cumulative total of 406 RA patients. The most symptomatic joint other than the routine joints was additionally scanned. Power Doppler (PD) and gray-scale images were scored semiquantitatively. Eight-joint scores were calculated as the sum of individual scores for the routine joints. RESULTS: The most symptomatic joint was found among the routine joints in 209 patients (Group A) and in other joints in 148 (Group B). The PD scores of the most symptomatic joint correlated well with the 8-joint scores in Group A (rs = 0.66), but not in Group B (rs = 0.33). The sensitivity and specificity of assessment of the most symptomatic joint for routine assessment positivity were high (84.0% and 100%, respectively) in Group A, but low (50.0% and 61.8%, respectively) in Group B. Additional examination detected synovitis in 38% of Group B with negative results in the routine. CONCLUSIONS: On-demand US assessment in the most symptomatic joint, combined with the routine assessment, is useful for detecting RA synovitis.
