ROS-driven structural and functional fibrinogen modifications are reverted by interleukin-6 inhibition in Giant Cell Arteritis.

BACKGROUND: Cranial and extra-cranial vascular events are among the major determinants of morbidity and mortality in Giant Cell Arteritis (GCA). Vascular events seem mostly of inflammatory nature, although the precise pathogenetic mechanisms are still unclear. We investigated the role of oxidation-induced structural and functional fibrinogen modifications in GCA. The effects of the anti-IL6R tocilizumab in counteracting these mechanisms were also assessed. MATERIALS AND METHODS: A cross-sectional study was conducted on 65 GCA patients and 65 matched controls. Leucocyte reactive oxygen species (ROS) production, redox state, and fibrinogen structural and functional features were compared between patients and controls. In 19 patients receiving tocilizumab, pre vs post treatment variations were assessed. RESULTS: GCA patients displayed enhanced blood lymphocyte, monocyte and neutrophil ROS production compared to controls, with an increased plasma lipid peroxidation and a reduced total antioxidant capacity. This oxidative impairment resulted in a sustained fibrinogen oxidation (i.e. dityrosine content 320 (204-410) vs 136 (120-176) Relative Fluorescence Units (RFU), p < 0.0001), with marked alterations in fibrinogen secondary and tertiary structure [intrinsic fluorescence: 134 (101-227) vs 400 (366-433) RFU, p < 0.001]. Structural alterations paralleled a remarkable fibrinogen functional impairment, with a reduced ability to polymerize into fibrin and a lower fibrin susceptibility to plasmin-induced lysis. In patients receiving tocilizumab, a significant improvement in redox status was observed, accompanied by a significant improvement in fibrinogen structural and functional features (p < 0.001). CONCLUSIONS: An impaired redox status accounts for structural and functional fibrinogen modifications in GCA, suggesting a potential role of tocilizumab for cardiovascular prevention in GCA.

Prevalence and clinical associations of ultrasound-confirmed enthesitis in systemic lupus erythematosus.

OBJECTIVES: To assess the prevalence of US-confirmed enthesitis in a cohort of patients with SLE and to analyse the clinical associations to enthesitis during the course of SLE. METHODS: In a retrospective analysis of the SLE cohort of the Lupus Unit of the Careggi University Hospital, US examinations of SLE patients presenting with tender and/or swollen joints were retrieved to assess the presence of enthesitis. Patients with US-proven enthesitis were compared with SLE controls with tender and/or swollen joints who showed no US evidence of enthesitis. Clinical and laboratory features were compared at disease onset and during follow-up. RESULTS: A total of 400 patients fulfilling EULAR/ACR classification criteria for SLE were assessed. Of these, 106 underwent articular US examination. Evidence of enthesitis was found in 31/106 (29.2%) patients. Seventy-one patients without US-enthesitis were included as controls; four were excluded due to lack of follow-up data. Laboratory and clinical features were comparable between cases and controls at disease onset. Throughout a median follow-up of 10.0 (interquartile range [IQR] 8.3-23.3) years for cases and 12.4 (IQR 7.2-13.3) years for controls, patients with enthesitis were less likely to develop renal involvement (22.6% vs 46.5%, P = 0.028) and failed B cell depletion more frequently (75.0% vs 0%). CONCLUSION: In SLE patients with clinically active joints, US-proven enthesitis is a fairly common finding. Enthesitis in SLE could be the hallmark of a distinct disease phenotype with less renal involvement, more arthritis and low response to anti-CD 20 therapy, potentially requiring a tailored treatment.

Clinical profile and evolution of patients with juvenile-onset Behçet's syndrome over a 25-year period: insights from the AIDA network.

Behçet's syndrome (BS) represents an understudied topic in pediatrics: the main aims of our study were to characterize demographic and clinical features of a cohort of BS patients with juvenile-onset managed in three tertiary referral centers in Italy, evaluate their evolution in the long-term, and detect any potential differences with BS patients having an adult-onset. Medical records of 64 juvenile-onset and 332 adult-onset BS followed-up over a 2-year period were retrospectively analyzed and compared. Mean age ± SD of first symptom-appearance was 10.92 ± 4.34 years with a female-to-male ratio of 1.06:1. Mucocutaneous signs were the most frequent initial manifestations, followed by uveitis. Throughout the disease course, genital aphthae (76.56%) and pseudofolliculitis (40.63%) prevailed among the mucocutaneous signs, while major organ involvement was represented by gastrointestinal and ocular involvement (43.75 and 34.38%, respectively). No significant differences emerged for both mucocutaneous signs and specific major organ involvement between juvenile-onset and adult BS patients. After excluding nonspecific abdominal pain, juvenile-onset BS patients were less frequently characterized by the development of major organ involvement (p = 0.027). Logistic regression detected the juvenile-onset as a variable associated with reduced risk of long-term major organ involvement (OR 0.495 [0.263-0.932], p = 0.029). In our cohort, juvenile-onset BS resembled the clinical spectrum of adult-onset patients. Pediatric patients with a full-blown disease at onset showed a more frequent mucocutaneous involvement. In addition, patients with juvenile-onset seemed to develop less frequently major organ involvement and had an overall less severe disease course.

Comparison of treatments for the prevention of fetal growth restriction in obstetric antiphospholipid syndrome: a systematic review and network meta-analysis.

Women with criteria and non-criteria obstetric antiphospholipid syndrome (APS) carry an increased risk of pregnancy complications, including fetal growth restriction (FGR). The management of obstetric APS traditionally involves clinicians, obstetricians and gynaecologists; however, the most appropriate prophylactic treatment strategy for FGR prevention in APS is still debated. We performed a systematic review and network meta-analysis (NetMA) to summarize current evidence on pharmacological treatments for the prevention of FGR in APS. We searched PubMed and Embase from inception until July 2020, for randomized controlled trials and prospective studies on pregnant women with criteria or non-criteria obstetric APS. NetMA using a frequentist framework were conducted for the primary outcome (FGR) and for secondary outcomes (fetal or neonatal death and preterm birth). Adverse events were narratively summarised. Out of 1124 citations, we included eight studies on 395 pregnant patients with obstetric APS treated with low-dose aspirin (LDA) + unfractionated heparin (UFH) (n = 132 patients), LDA (n = 115), LDA + low molecular weight heparin (n = 100), LDA + corticosteroids (n = 29), LDA + UFH + intravenous immunoglobulin (n = 7), or untreated (n = 12). No difference among treatments emerged in terms of FGR prevention, but estimates were largely imprecise, and most studies were at high/unclear risk of bias. An increased risk of fetal or neonatal death was found for LDA monotherapy as compared to LDA + heparin, and for no treatment as compared to LDA + corticosteroids. The risk of preterm birth was higher for LDA + UFH + IVIg as compared to LDA or LDA + heparin, and for LDA + corticosteroids as compared to LDA or LDA + LMWH. No treatment was associated with an increased risk of bleeding, thrombocytopenia or osteopenia.

Occurrence and predictive factors of high blood pressure, type 2 diabetes, and metabolic syndrome in rheumatoid arthritis: findings from a 3-year, multicentre, prospective, observational study.

OBJECTIVES: In rheumatoid arthritis (RA), "traditional" cardiovascular (CV) risk factors continue to be underdiagnosed and undertreated, thus increasing the risk of developing atherosclerosis. In this work, we evaluated the occurrence and predictive factors of "traditional" cardiovascular risk factors, with a focus on high blood pressure (HBP), type 2 diabetes (T2D), and metabolic syndrome (MetS), in participants with RA, in a 3-year, multicentre, prospective, observational study. METHODS: To assess the occurrence and predictive factors of HBP, T2D, and MetS, consecutive participants with RA, admitted to Italian Rheumatology Units, were evaluated in the GIRRCS (Gruppo Italiano di Ricerca in Reumatologia Clinica e Sperimentale) cohort, a 3-year, multicentre, prospective, observational study. RESULTS: In the present evaluation, 841 participants, who were fully followed up with 3-year of prospective follow-up were assessed. At the end of follow-up, a significant increased incidence of HBP, T2D, and MetS was recorded. Assessing predictive factors, the mean values of C-reactive protein during the follow-up were independent predictors of occurrence of those comorbidities, whereas participants maintaining remission showed a significant lower risk. Furthermore, therapy with hydroxychloroquine (HCQ) reduced the risk of occurrence of T2D and MetS. CONCLUSIONS: An increased incidence of HBP, T2D, and MetS was observed in assessed participants, prospectively followed-up. Furthermore, the analysis of predictive factors suggested that the rheumatoid pro-inflammatory process could increase the occurrence of these comorbidities. Conversely, metabolic and cardiovascular benefits of maintaining remission as well as of therapy with HCQ were reported.

SARS-CoV-2 infection among patients with systemic autoimmune diseases.

OBJECTIVES: This study aimed to evaluate the prevalence of clinically overt SARS-CoV-2 infection (COVID-19) among patients with systemic autoimmune diseases residing in Tuscany, and to compare it with that observed in the general Tuscan population. METHODS: In this cross-sectional study, Tuscan outpatients with systemic autoimmune diseases followed at a tertiary referral centre were telephonically interviewed between April 1st-14th 2020 to collect demographic and clinical data, information on ongoing immunomodulating/immunosuppressive treatments, and on the presence of symptoms suspected of SARS-CoV-2 or of a confirmed infection. RESULTS: 458 patients were interviewed [74% female, median age 56 years (IQR 43-68)]; 56% of them were receiving corticosteroids, 44% traditional disease-modifying anti-rheumatic drugs (DMARDs), of whom 23% hydroxychloroquine, 5% colchicine, while 41% were on biologic DMARDs (of whom 9% on tocilizumab). Thirteen patients reported symptoms suggesting SARS-CoV-2 infection. Of them, 7 had undergone nasopharyngeal swab and only one was positive and developed severe SARS-CoV-2 complications. Within our cohort, the prevalence of SARS-CoV-2 infection was therefore 0.22% (0.01-1.21%), comparable to that observed in the general population of Tuscany [0.20% (0.20-0.21%), p = .597]. CONCLUSIONS: Patients with systemic autoimmune diseases do not seem to carry an increased risk of SARS- CoV-2 infection as compared to the general population.

Long-term effectiveness and safety of secukinumab for treatment of refractory mucosal and articular Behçet's phenotype: a multicentre study.

OBJECTIVE: To evaluate the effectiveness and safety of secukinumab in patients with a mucosal and articular Behçet's phenotype resistant to conventional and biologic treatment. METHODS: A multicentre retrospective study was performed on 15 patients with a mucosal and articular phenotype of Behçet's syndrome fulfilling the International Criteria for Behçet's Disease and refractory to treatment with colchicine, disease-modifying antirheumatic drugs and at least one antitumour necrosis factor-α agent. Minimum follow-up was set at 6 months. Six patients with a polyarticular involvement were treated with secukinumab 300 mg/month, while all other cases received secukinumab 150 mg/month. Dose increase from 150 to 300 mg per month and shortening of administration frequency were allowed for poor disease control. Response evaluation was based on the number of oral ulcers in the previous 28 days and Disease Activity Score-28 for articular manifestations. RESULTS: At 3 months of follow-up, nine (66.7%) patients achieved a response (complete or partial), and this proportion further increased to 86.7% at 6 months, 76.9% at 12 months, 90.0% at 18 months and 100.0% after 24 months. Notably, all patients who started with secukinumab 300 mg/month achieved complete response by month 6. Seven (46.7%) patients could achieve a response only after switching to a higher dosage. CONCLUSIONS: Our study suggests that secukinumab at a dose of 150 and 300 mg per month is safe and effective for the long-term treatment of patients with Behçet's syndrome with a mucosal and articular phenotype refractory to previous treatments. Notably, secukinumab 300 mg/month resulted in superior complete mucosal and articular responses with no serious or dose-related adverse effects.

Long-Term Effectiveness of Secukinumab in Patients with Axial Spondyloarthritis.

OBJECTIVES: The primary aim of our study was to evaluate long-term efficacy of secukinumab (SCK) in patients with axial spondyloarthritis (axSpA); secondary aims were to evaluate drug retention rate and to identify differences in the clinical and laboratory assessment according to axSpA clinical features, dosage administered, and biologic treatment lines. Patients and Methods. We collected clinical, demographical, and treatment data from 39 patients affected by axSpA consecutively treated with SCK. Laboratory assessment was based on inflammation parameters; clinical assessment was performed with the Ankylosing Spondylitis Disease Activity Score- (ASDAS-) CRP and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Data were recorded at baseline and every 3 months for the first year and then every 6 months in the second year. RESULTS: Twelve males and 27 females were enrolled; both BASDAI and ASDAS-CRP showed a statistically significant reduction during the observation period (p < 0.0001 and p < 0.0001, respectively). C-reactive protein significantly decreased (p = 0.006), with significant reduction at the post hoc analysis between baseline and both 6-month evaluation (p = 0.02) and 24-month visit (p = 0.036). No statistical significance was observed in BASDAI and ASDAS-CRP improvement (p = 0.482 and p = 0.164, respectively) between different dosages administered. No significant differences emerged in the BASDAI and ASDAS-CRP variations between biologic-naïve patients and subjects previously failing to tumour necrosis factor (TNF) inhibitors (p = 0.53 and p = 0.148, respectively). At the end of our observation, 7 out of 39 patients discontinued SCK. The global retention rate at the end of the study period was 78.2%, without any significant differences between biologic-naïve and anti-TNF-failure patients (p = 0.619) or between subjects administered with different SCK dosages (p = 0.614). No adverse events were reported. CONCLUSIONS: In our cohort, SCK has proved a remarkable effectiveness regardless biologic treatment line and dosages employed. As suggested by the notable drug retention rate, SCK has been able to maintain its effectiveness over a considerable long period of treatment.

Adalimumab effectively controls both anterior and posterior noninfectious uveitis associated with systemic inflammatory diseases: focus on Behçet's syndrome.

BACKGROUND: To compare the efficacy of Adalimumab (ADA) in noninfectious anterior uveitis (AU) and posterior segment (PS) involvement, associated with different conditions, with a focus on Behçet's syndrome (BS). METHODS: In this retrospective, multicenter post-hoc study, we evaluated the efficacy of ADA in terms of ocular control and relapses in 96 patients with AU and PS uveitis, either idiopathic (IU) or associated with BS or with other systemic disorders (OSD) (Juvenile Idiopathic Arthritis, Psoriatic Arthritis, Ankylosing Spondylitis, Vogt-Koyanagi-Harada, Inflammatory Bowel Disease), followed in three tertiary referral centers. RESULTS: Ninety-six patients (45 AU; 51 PS uveitis) were included. Eleven had IU, 58 BS, and 27 OSD. All patients with AU achieved complete long-term ocular control. In PS uveitis, 89%, 67% and 100% of patients with BS, IU and OSD achieved ocular control at the last follow-up (> 12 months), respectively. The lowest ocular relapse rate occurred in patients with AU with BS (1/13) or IU (0/2). ADA accounted for long-term disease control, and no predictors of ocular control and relapse were identified; particularly, ocular relapses seemed not related to systemic ones. Macular edema resolved in 75% and 67% of PS uveitis with BS and IU, respectively. CONCLUSIONS: ADA controls both anterior and posterior uveitis, with an efficacy similar in IU, BS and OSD patients. In BS, the efficacy of ADA seems to be independent of demographic and clinical characteristics, and ocular relapses mostly occurred independently from systemic ones. Based on our results, ADA may represent a valid alternative in anterior refractory uveitis.

Alveolar haemorrhage in ANCA-associated vasculitis: Long-term outcome and mortality predictors.

INTRODUCTION: Alveolar haemorrhage (AH) is considered an important cause of morbidity and early mortality in anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitides (AAV). OBJECTIVES: The aim of this study was to identify predictors of outcome in patients with AH-AAV and to evaluate outcome and causes of death in this subset. MATERIALS AND METHODS: A multicenter retrospective study was conducted in 29 Italian Centers. Clinicians were asked to recruit all patients diagnosed with AAV-associated AH during the last 10 years, from 2007 to 2016. Univariate and multivariable analysis were performed. RESULTS: One-hundred and six patients were included (median age at onset of 55 years [IQR 42-67]). The majority were ANCA-positive (PR3 57.1%, MPO 33.7%) and 72.6% had also renal involvement. At presentation, anaemia was shown in 97 (92.4%) patients, hemoptysis in 54 (51.9%), respiratory failure in 68 (66.7%), of whom 48 (70.6%), requiring respiratory support. At the end of the 37 months [IQR 13-77] follow-up, 19/106 (17.9%) patients were dead. The main causes of death were active disease and infections. By stepwise regression analysis, age >65 years (HR 3.66 [95% CI 1.4-9.51], p = 0.008) and the need for respiratory support (HR 4.58 [95% CI 1.51-13.87], p = 0.007) at AH onset were confirmed to be predictive of mortality. CONCLUSIONS: Predictors of outcome in AAV-AH were determined. Factors related to the patient's performance status and the severity of the lung involvement strongly influenced the outcome. Balancing harms and benefits for the individual patient in induction and maintenance treatment strategies is crucial.

The Presence of Uveitis Is Associated with a Sustained Response to the Interleukin (IL)-1 Inhibitors Anakinra and Canakinumab in Behçet's Disease.

Purpose: To identify factors associated with sustained response to interleukin (IL)-1 inhibition among demographic, clinical and therapeutic data in patients with Behçet disease (BD).Methods: BD patients treated with anakinra or canakinumab were enrolled. Patients were divided into two groups according to the clinical response: group 1 included subjects showing a treatment duration of at least 52 weeks and no secondary inefficacy during the first follow-up year; the remaining patients were included in the group 2. Demographic, clinical and therapeutic data were analyzed to identify significant differences between groups.Results: Eighteen patients were included in group 1 and 18 patients in group 2. A better response to IL-1 inhibitors was significantly more common among patients with BD-related uveitis (p = 0.006) and patients with a longer disease duration (p = 0.03).Conclusion: IL-1 blockade is effective in BD, especially in the subset of patients presenting eye involvement and in those with long-lasting disease.

Subclinical and clinical atherosclerosis in rheumatoid arthritis: results from the 3-year, multicentre, prospective, observational GIRRCS (Gruppo Italiano di Ricerca in Reumatologia Clinica e Sperimentale) study.

BACKGROUND: Rheumatoid arthritis (RA) is associated with an increased risk of morbidity and mortality, when compared with general population, largely due to enhanced atherosclerotic disease. In this work, we aimed at assessing both occurrence and predictive factors of subclinical and clinical atherosclerosis in RA. METHODS: From January 1, 2015, to December 31, 2015, consecutive participants with RA, admitted to Italian Rheumatology Units, were assessed in the GIRRCS (Gruppo Italiano di Ricerca in Reumatologia Clinica e Sperimentale) cohort. After that, those participants were followed up in a 3-year, prospective, observational study, assessing the occurrence of subclinical and clinical atherosclerosis and possible predictive factors. McNemar test was employed to assess the changes in subclinical and clinical atherosclerosis, and regression analyses exploited the ORs for the occurrence of those comorbidities. RESULTS: We analysed 841 participants, mostly female (82.2%) and with median age of 60 years (range 21-90). The remission was achieved and maintained by 41.8% of participants during the follow-up. We observed an increased rate of subclinical atherosclerosis at the end of follow-up (139 vs 203 participants, p < 0.0001), particularly in participants with a disease duration less than 5 years at baseline (70 participants vs 133 participants, p < 0.0001). Type 2 diabetes (T2D) (OR 4.50, 95%CI 1.74-11.62, p = 0.002), high blood pressure (OR 2.03, 95%CI 1.04-4.14, p = 0.042), ACPA (OR 2.36, 95%CI 1.19-4.69, p = 0.014) and mean values of CRP during the follow-up (OR 1.07, 95%CI 1.03-1.14, p = 0.040) were significantly associated with higher risk of subclinical atherosclerosis. We observed an increased rate of clinical atherosclerosis at the end of follow-up (48 vs 76 participants, p < 0.0001). T2D (OR 6.21, 95%CI 2.19-17.71, p = 0.001) was associated with a significant risk of clinical atherosclerosis. The achievement and the maintenance of remission reduced the risk of subclinical (OR 0.25, 95%CI 0.11-0.56, p = 0.001) and clinical atherosclerosis (OR 0.20, 95%CI 0.09-0.95, p = 0.041). CONCLUSIONS: We reported an increased prevalence and incidence of both subclinical and clinical atherosclerosis in 3-year prospectively followed participants, mainly in the subset with a duration of disease less than 5 years. The achievement and the maintenance of remission are associated with a reduction of the risk of subclinical and clinical atherosclerosis. Among "traditional" cardiovascular risk factors, participants with T2D showed a higher risk of clinical and subclinical atherosclerosis.

Intravenous immunoglobulin therapy: a snapshot for the internist.

Intravenous immunoglobulins are the cornerstone for the treatment of primary humoral immunodeficiencies and may be used for a great number of other autoimmune, neurological and hematological conditions as well. Given their wide application, the possibility of running across a patient who needs this kind of therapy is becoming increasingly common. Generally, intravenous immunoglobulins are well tolerated. However, numerous adverse reactions ranging from mild to severe have been reported and linked to patient- and product-related factors. For all these reasons, we present herein a comprehensive review of the on- and off-label applications of intravenous immunoglobulins and provide a guide for the internist how to minimize the risk of adverse reactions and manage them.

Different drug survival of first line tumour necrosis factor inhibitors in radiographic and non-radiographic axial spondyloarthritis: a multicentre retrospective survey.

OBJECTIVES: Good drug survival of tumour necrosis factor inhibitors (TNFi) has been shown in axial spondyloarthritis (axSpA) patients treated in real-life setting. However, few studies have compared drug survival of the first TNF inhibitor between radiographic axSpA (r-axSpA) and non-radiographic axSpA (nr-axSpA) patients in real-world clinical practice. The aim of this work was to evaluate the effectiveness by assessing the retention rate of first-line TNFi in r-axSpA and nr-axSpA patients. Baseline predictive factors for TNFi discontinuation were also evaluated. METHODS: We retrospectively assessed axSpA patients, who underwent first line therapy with TNFi. Demographic and clinical data was obtained through structured interview, review of medical records and physical examination. Disease activity indices such as the Bath Ankylosing Spondylitis Metrology Index (BASMI), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Ankylosing Spondylitis Disease Activity Score evaluating C Reactive Protein (ASDAS-CRP), Leeds Enthesitis Index (LEI) were assessed at baseline. Moreover Health Assessment QuestionnaireDisability Index (HAQ), erythrocyte sedimentation rate (ESR, mm/h), CRP (mg/dl) and HLA-B27 were recorded as well. Data on x-ray and magnetic resonance imaging of the sacroiliac joints were also collected. Drug retention rates were analysed using Kaplan-Meier curves; log-rank test was performed to demonstrate differences in the survival functions. Cox regression models were used to estimate the inference of several disease and clinical characteristics on drug discontinuation. RESULTS: Drug survival of first-line TNFi was significantly lower in patients who had nr-axSpA than in those with r-axSpA (p=0.005). HLA-B27 frequency was higher in patients with x-ray sacroiliitis than in those with nr-axSpA (p=0.01) as well as mean CRP serum level (p=0.0001), whereas both mean BASDAI and LEI score were higher in patients with nr-axSpA than in those with r-axSpA (p=0.018 and p=0.007, respectively). Global retention rate in our cohort was 60.34% with mean survival time (MST) of 58.68 months (95% CI 47.93-69.42). MST for patients diagnosed with r-axSpA was 66.79 months (95% CI 53.54-80.04) and 39.05 months (95% CI 24.12-53.99) for those with nr-axSpA. Moreover, nr-axSpA (HR 1.620), higher BMI (HR 1.093) and BASFI, (HR 1.192) had an impact on drug discontinuation, whereas HLA-B27 presence (HR. 0.523) had protective effect. CONCLUSIONS: Effectiveness of TNFi, seems to be lower in nr-axSpA patients than in those with r-axSpA. In addition obesity and functional disability negatively impact the persistence on first line TNFi in axSpA patients in real life setting.

Adalimumab Accounts for Long-Term Control of Noninfectious Uveitis Also in the Absence of Concomitant DMARD Treatment: A Multicenter Retrospective Study.

OBJECTIVE: This study was aimed at assessing the long-term ocular control of adalimumab (ADA) in a large real-world population with noninfectious primary or secondary uveitis, focusing on the steroid-sparing effect and on disease-modifying antirheumatic drug (DMARD) cotreatment. METHODS: In this retrospective, multicenter study, the efficacy of ADA was evaluated in terms of ocular control, changes in best-corrected visual acuity (BCVA), corticosteroid-sparing effect, and drug retention rate, overall and stratified according to DMARD cotreatment. RESULTS: 106 patients were included. 88.7% had an associated systemic disease. After 6 and 12 months, proportions of patients with effective ocular control were 83.7% and 83.3%, respectively. At last the follow-up, 94.6% of patients had satisfactory ocular control. No difference in terms of ocular control at all time points emerged among patients starting ADA for ocular vs. systemic involvements. Patients with poor baseline BCVA remained stable or improved, while those with good BCVA hardly worsened. At 6 and 12 months, the median dose of prednisone significantly reduced to 5 mg/day (0-5) and 2.5 mg/day (0-5) (p < 0.001). Over a median follow-up of 36 months, 38 subjects discontinued ADA treatment. Mild to moderate side effects were reported in 7 patients (6.6%). ADA ocular control, corticosteroid-sparing effect, and drug retention rate were not influenced by the concomitant use of DMARDs. CONCLUSION: The long-term ocular control of ADA in noninfectious primary or secondary uveitis is confirmed, also for BCVA preservation. Concomitant use of DMARDs does not provide additional benefits to ADA alone in terms of ocular control, steroid spare, and drug retention rate.

The right place of interleukin-1 inhibitors in the treatment of Behçet's syndrome: a systematic review.

Behçet's syndrome (BS) is a chronic (auto)-inflammatory disorder characterized by different clusters of symptoms, including mucocutaneous and ocular involvements. Interleukin-1 inhibitors anakinra (ANA), canakinumab (CAN), and gevokizumab (GEV) represent a promising therapeutic alternative in BS. To date, evidence on the use of ANA, CAN, and GEV is mainly based on small isolated studies or case series, and the real place of anti-IL1 agents in the treatment of BS is still unclear. We performed a systematic review of current evidence on the efficacy and safety of anti-IL1 agents in BS. The PubMed search yielded a total of 398 references, from which we retrieved 24 studies for inclusion (4 clinical trials, 6 observational studies, 14 case reports, case series or letters to the editor). Four studies evaluated the overall efficacy of IL-1 inhibitors, 15 studies focused on the specific efficacy of ANA, whereas efficacy of CAN and GEV was evaluated in 8 and 3 studies, respectively. Both ANA and CAN were associated with good control of mucocutaneous and ocular manifestations. ANA resulted effective also for osteoarticular manifestations. GEV was studied only for ocular manifestations, but gave contrasting results. Discordant evidence supports the use of ANA and CAN in pediatric setting and for first-line treatment of general BS manifestations. Most frequent side effects were local or diffuse cutaneous reactions and injection site reactions, particularly for ANA treatment. Blocking the IL-1 pathway could be an effective therapeutic strategy in particular BS involvements.

Efficacy of the anti-IL 17 secukinumab in refractory Behçet's syndrome: A preliminary study.

OBJECTIVE: To evaluate the efficacy and safety of secukinumab in Behçet's patients with active mucocutaneous and articular manifestations refractory to previous treatments. METHODS: We retrospectively evaluated 5 patients treated with the IL17-inhibitor secukinumab and diagnosed with Behçet according to ISG/ICBD criteria. All patients had active mucocutaneous and articular manifestations refractory to colchicine, conventional DMARDs and at least one anti-TNFα agent. Four patients received secukinumab in the dose of 150 mg/monthly since also fulfilling the criteria for ankylosing spondylitis, while the fifth patient received secukinumab 300 mg/monthly because she met psoriatic arthritis criteria. Achievement of response was based on the number of oral ulcers, BASDAI and ASDAS for articular involvement, and BDCAF for Behçet activity. Complete response was defined as: i) decrease ≥50% in the number of oral ulcers; ii) BASDAI index <4; iii) ASDAS index <1.4; iv) decrease of 50% or more in BDCAF index. RESULTS: The patient starting secukinumab 300 mg/month successfully achieved complete response within 3 months. Complete response was maintained during all 9-months follow-up. Among the 4 subjects starting secukinumab 150 mg/month, two achieved complete response at month 6, but one relapsed. This patient and the two who not achieved complete response at month 6 were switched to secukinumab 300 mg/month. Within 3 months from the dosage increase, all three subjects successfully (re)achieved complete response. CONCLUSION: Our study suggested for the first time that secukinumab (either 150 mg and 300 mg/month) improved active mucocutaneous manifestations refractory to previous treatments, while secukinumab 300 mg/monthly resulted superior in inducing articular and complete response in Behçet's patients.
