RESUMEN
Background: Little is known about the relationship between the disease activity of Behçet disease (BD) and the incidence of inflammatory major organ events. Objectives: In this prospective registry study, we investigated the association between the Behçet Disease Current Activity Form (BDCAF) and incidence of inflammatory major organ events, defined as the inflammation of the ocular, central nervous, intestinal, and vascular systems in BD. Methods: We enrolled participants from Japanese multicenter prospective cohorts. The BDCAF was evaluated annually. BD-related symptoms, including inflammatory major organ events, were monitored. The association between BDCAF and inflammatory major organ events was analyzed by time-to-event analysis. An unsupervised clustering of the participants' BDCAF, therapeutic agents, and multiple serum cytokines was also performed to examine their association with inflammatory major organ events. Results: A total of 260 patients were included. The patients had a median BDCAF score of 2 [Interquartile range, 1-3] at the enrolment and remained disease active at 1- and 2-year follow-ups, indicating residual disease activity in BD. Patients with a BDCAF score of 0 had a longer inflammatory major organ event-free survival at 52 weeks than those with a score of 1 or higher (p=2.2 x 10-4). Clustering analysis revealed that patients who did not achieve remission despite treatment with tumor necrosis factor inhibitors had high serum inflammatory cytokine levels and incidences of inflammatory major organ events. Among the elevated cytokines, IL-6 was associated with inflammatory major organ events. Conclusion: This study suggests that treatment strategies targeting overall disease activity and monitoring residual serum IL-6 may help prevent inflammatory major organ events in BD.

Objectives Chronic progressive neuro-Behcet's disease (CPNB) is characterized by progressive deterioration leading to disability. Methotrexate (MTX) has been shown to have beneficial effects on CPNB. However, while infliximab has been found to be effective for patients with inadequate responses to MTX, the appropriate timing for the introduction of infliximab remains unclear. We explored the effects of intervals before the introduction of infliximab on the functional outcome. Methods A retrospective analysis was performed for patients with CPNB who received infliximab and were followed up until October 2015. Functional disability was rated by the Steinbrocker functional classification as used in rheumatoid arthritis. Correlations between the outcomes and intervals before the introduction of infliximab were then analyzed by Spearman's rank correlation test. Patients Eleven patients with CPNB [8 men, 3 women, age 35.2±9.3 years old (mean±standard deviation)] who met the international classification criteria for Behcet's disease were included. Results All 11 patients had received MTX prior to infliximab. The intervals from the onset to the introduction of infliximab and the follow-up periods were 26.6±35.1 months and 65.2±43.6 months [mean±standard deviation], respectively. Among the 11 patients, 2 still showed progression after the introduction of infliximab. The functional disability grades after infliximab treatment were significantly correlated with the intervals from the onset of CPNB to the introduction of infliximab (r=0.6177, p=0.0476). Conclusion The results indicate that the delayed introduction of infliximab leads to irreversible functional disability in CPNB. Thus, it is recommended that infliximab be administered as soon as possible for CPNB patients with inadequate responses to MTX.

Rupture of inflammatory aortic aneurysm associated with retroperitoneal fibrosis (RF) is rare. We report a 62-year-old man with an inflammatory abdominal aortic aneurysm (IAAA) complicated with idiopathic RF, resulting in a contained rupture of the common iliac artery. The patient also presented with mild renal insufficiency due to urethral obstruction and left hydronephrosis. Surgical procedures including graft replacement and ureterolysis relieved the symptoms. Postoperative immunosuppressive treatment using corticosteroid and methotrexate successfully maintained clinical remission without signs of recurrence of RF and IAAA at the 2-year follow-up.
RESUMEN
Sarcoidosis is a multisystem disease with an unknown etiology and is characterized by the formation of noncaseating granulomas in the affected organs. We present the case of a 69-year-old male Japanese patient with bilateral hilar lymphadenopathy on chest radiographs for more than 10 years, left without further investigation. The patient reported no clinical symptoms. Chest computed tomography revealed ground-glass opacities and reticular shadows in both lungs, along with bilateral hilar and mediastinal lymphadenopathy. Lymphocytosis was observed in bronchoalveolar lavage fluid. Pathological examination of transbronchial lung biopsy revealed noncaseating, epithelioid granulomas congruous with sarcoidosis, together with other findings. There were no abnormalities on electrocardiogram, echocardiogram, and ophthalmic examination.For progressive dyspnea on exertion, systemic corticosteroid therapy with oral prednisolone (25 mg/day) was initiated in 2017 and gradually tapered. Despite this intervention, the decline in forced vital capacity (FVC) was accelerated. Three years later, the patient noticed swelling in his right wrist. Further investigation revealed elevated anti-cyclic citrullinated peptide antibodies and absence of noncaseating epithelioid granuloma on surgical biopsy, leading to the diagnosis of rheumatoid arthritis (RA). Thereafter, the anti-fibrotic agent nintedanib was initiated, because interstitial lung disease (ILD) was considered to have converted into a progressive fibrosing phenotype (PF-ILD) with overlapping RA-associated lung involvement. With treatment, the progression of decline in FVC was slowed, although home oxygen therapy was introduced.

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.

Objective: Severe digital ischemia, including digital ulcers and gangrene, is considered rare in patients with antisynthetase antibodies. This study aimed to elucidate the clinical features of antisynthetase-positive patients complicated with digital ulcers and/or gangrene using a systematic literature review and case series in a single-center cohort. Methods: A systematic literature review was conducted to identify reports describing antisynthetase-positive cases with digital ulcers and/or gangrene. Our cohort of consecutive patients with antisynthetase antibodies was stratified by the history of severe digital ischemia. Demographic and clinical features and outcomes in patients with severe digital ischemia identified in the systematic literature review and our cohort were compared with those in patients without severe digital ischemia in our cohort. Results: The systematic literature review revealed 12 antisynthetase-positive patients with severe digital ischemia from one case series and eight case reports. Seven (7%) of 100 patients with antisynthetase antibodies in our cohort had a record of severe digital ischemia. Severe digital ischemia was often found at presentation and was associated with the classification of systemic sclerosis with or without myositis overlap. Clinical features associated with severe digital ischemia in antisynthetase-positive patients included Raynaud's phenomenon (p < 0.001), digital pitting scars (p = 0.001), and nailfold capillary abnormality (p = 0.02). Outcomes of severe digital ischemia were generally favorable with vasodilators. Conclusion: Severe digital ischemia is an overlooked complication in antisynthetase-positive patients. Antisynthetase antibodies should be measured in patients presenting with digital ulcers or gangrene, especially in those with systemic sclerosis phenotype and features associated with antisynthetase antibodies in the absence of systemic sclerosis-specific autoantibodies.
RESUMEN
OBJECTIVE: To assess apremilast's impact on patient quality of life (QoL) in active Behçet's syndrome and correlations between improvement in patients' QoL and efficacy measures in the phase 3 RELIEF study. METHODS: QoL measures included Behçet's Disease QoL (BDQoL), 36-Item Short-Form Health Survey V.2 (SF-36v2) Physical/Mental Component Summary (PCS/MCS) and eight subscale scores, focusing on Physical Functioning (PF). Pearson's correlation coefficients assessed relationships between efficacy endpoints (oral ulcer count, oral ulcer pain, Behçet's Syndrome Activity Scale (BSAS), Behçet's Disease Current Activity Form (BDCAF)) and QoL endpoints for apremilast at Week 12. RESULTS: Apremilast (n=104) demonstrated significantly greater improvements versus placebo (n=103) in SF-36v2 PCS (3.1 vs 0.9), MCS (4.6 vs â0.7) and PF (2.9 vs 0.14), respectively (all p<0.05). Mild correlations were observed in improvements of SF-36v2 measures (PCS, MCS, PF) with oral ulcer count (r=-0.11, PCS), and change in oral ulcer pain from baseline (r=-0.28, PCS; r=-0.10, PF) and BSAS (r=-0.38, PCS; r=-0.20, PF; r=-0.16, MCS). Correlations among BDCAF and SF-36v2 components and BDQoL were variable. BDQoL showed mild/moderate correlations with SF-36v2 components (r=-0.18, PCS; r=-0.13, PF; r=-0.45, MCS). CONCLUSIONS: Apremilast was associated with significant improvements in QoL measures of SF-36v2 PCS, MCS and PF and BDQoL in patients with Behçet's syndrome. Correlations of improvement among QoL endpoints support the beneficial clinical effects of apremilast in Behçet's syndrome. TRIAL REGISTRATION NUMBER: NCT02307513.

Periaortitis is a rare vascular manifestation and is often associated with retroperitoneal fibrosis. Herein, we describe a case of periaortitis accompanied by retroperitoneal ï¬brosis in a patient who developed acute kidney insufficiency due to bilateral ureteral stenosis. Ultrasonography at presentation detected thickness of the outer layer of the bilateral common iliac artery and right internal and external iliac arteries, consistent with periaortitis. Moreover, follow-up ultrasound images revealed subsiding of the thickness of the arterial wall in response to treatment with corticosteroids. Because of its noninvasiveness and handiness, ultrasonography has become popular for the assessment of large vessels in clinical practice, particularly monitoring for affected lesions. Computed tomography, magnetic resonance imaging, and positron emission tomography are currently used for the diagnosis and monitoring of periaortitis, but in this case, ultrasonography was utilized in the diagnosis and monitoring of periaortitis as a supportive imaging modality, as the use of contrast agents was contraindicated because of renal insufficiency.

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: 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: 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.

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.

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.

Objective: To investigate histologic features of immunological components in the primary tumor site of patients with cancer-associated myositis (CAM) by focusing on tumor-infiltrating lymphocytes (TILs) and tertiary lymphoid structures (TLSs), which play major roles in antitumor immunity. Methods: Cancer-associated myositis patients were selected from the single-center idiopathic inflammatory myopathy cohort based on the availability of primary tumor specimens obtained before the introduction of immunomodulatory agents. Control cancer subjects without CAM were selected from the cancer tissue repository at a ratio of 1:2 matched for demographics and cancer characteristics of CAM cases. A series of immunohistochemical analyses was conducted using sequential tumor sections. TLS was defined as an ectopic lymphoid-like structure composed of DC-LAMP+ mature dendritic cells, CD23+ follicular dendritic cells (FDCs) and PNAd+ high endothelial venules. TLS distribution was classified into the tumor center, invasive margin, and peritumoral area. Results: Six CAM patients and 12 matched non-CAM controls were eligible for the study. There was no apparent difference in the density or distribution of TILs between the groups. TLSs were found in 3 CAM patients (50%) and 4 non-CAM controls (33%). TLSs were exclusively located at the tumor center or invasive margin in CAM cases but were mainly found in the peritumoral area in non-CAM controls. FDCs and class-switched B cells colocalized with follicular helper T cells were abundantly found in the germinal center-like area of TLSs from CAM patients compared with those from non-CAM controls. Conclusion: The adaptive immune response within TLSs in the primary tumor site might contribute to the pathogenic process of CAM.
RESUMEN
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.

Progressive multifocal leukoencephalopathy (PML) is a rare opportunistic infection of the central nervous system caused by reactivation of JC virus (JCV). Typical PML shows confluent, bilateral but asymmetric, subcortical lesions in the supratentorial white matter on magnetic resonance imaging (MRI). We report here a 50-year-old woman with systemic lupus erythematosus complicated with lymphoma who developed PML with atypical brain MRI findings limited to the infratentorial area at presentation. She presented with numbness on the right side of the face, including her tongue, clumsiness of the right hand, and gait disturbance, after completion of remission induction therapy for lymphoma, including rituximab. Brain MRI demonstrated a solitary lesion limited to the cerebellum and brainstem, but a definitive diagnosis could not be made from cerebrospinal fluid study or tentative histologic evaluation of brain biopsy specimens. Despite methylprednisolone pulse therapy, her neurological deficits progressively worsened. One month later, in-depth analysis of her cerebrospinal fluid and brain biopsy specimens confirmed the presence of JCV. Eventually, the localised unilateral crescent-shaped cerebellar lesions on MRI expanded to the contralateral cerebellum, middle cerebellar hemisphere, pons, and midbrain and finally developed multifocal invasion into the white matter of the cerebral hemispheres. Our case suggests that PML could first present with a solitary infratentorial lesion in immunocompromised patients.

BACKGROUND: We hypothesized that Behçet's disease (BD) consists of several clinical subtypes with different severity, resulting in heterogeneity of the disease. Here, we conducted a study to identify clinical clusters of BD. METHODS: A total of 657 patients registered in the Yokohama City University (YCU) regional BD registry between 1990 and 2018, as well as 6754 patients who were initially registered in the Japanese Ministry of Health, Labour and Welfare (MHLW) database between 2003 and 2014, were investigated. The YCU registry data regarding the clinical manifestations of BD, human leukocyte antigen (HLA) status, treatments, and hospitalizations were analyzed first, followed by similar analyses of the MHLW for validation. A hierarchical cluster analysis was independently performed in both patient groups. RESULTS: A hierarchical cluster analysis determined five independent clinical clusters in the YCU cohort. Individual counterparts of the YCU clusters were confirmed in the MHLW registry. Recent phenotypical evolutions of BD in Japan, such as increased gastrointestinal (GI) involvement, reduced complete type according to the Japan Criteria, and reduced HLA-B51 positivity were associated with chronologically changing proportions of the clinical clusters. CONCLUSIONS: In this study, we identified independent clinical clusters among BD patients in Japan and found that the proportion of each cluster varied over time. We propose five independent clusters namely "mucocutaneous", "mucocutaneous with arthritis", "neuro", "GI", and "eye."

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.
