Behçet's Disease Uveitis.

Uveitis in Behçet's disease (BD) is frequent (40% of cases) and is a major cause of morbidity. The age of onset of uveitis is between 20 and 30 years. Ocular involvement includes anterior, posterior, or panuveitis. Uveitis may be the first sign of the disease in 20% of cases or it may appear 2 or 3 years after the first symptoms. Panuveitis is the most common presentation and is more commonly found in men. Bilateralization usually occurs on average 2 years after the first symptoms. The estimated risk of blindness at 5 years is 10-15%. BD uveitis has several ophthalmological features that distinguish it from other uveitis. The main goals in the management of patients are the rapid resolution of intraocular inflammation, the prevention of recurrent attacks, the achievement of complete remission, and the preservation of vision. Biologic therapies have changed the management of intraocular inflammation. The aim of this review is to provide an update to a previous article by our team on pathogenesis, diagnostic approaches, and the therapeutic strategy of BD uveitis.

Neutrophilic dermatosis and hidradenitis suppurativa in patients with Behçet's disease: A neutrophilic disease in the spectrum of autoinflammatory syndromes.

BACKGROUND: Association of neutrophilic dermatosis (ND), hidradenitis suppurativa (HS) and Behçet's disease (BD) and shared efficacy of TNFα axis blockade suggests common physiopathology. OBJECTIVES: To investigate the clinical features and therapeutic response of ND and HS associated with BD. METHODS: We identified 20 patients with ND or HS associated with BD among 1462 patients with BD. RESULTS: We analysed 20 (1.4%) patients diagnosed with ND or HS associated with BD: 13 HS, 6 pyoderma gangrenosum (PG), and 1 SAPHO. Our 6 PG cases over 1462 BD patients accounts for 400/100 000 prevalence. Thirteen had bipolar aphthosis, 6 vascular, 5 neurologic, and 4 ocular involvements. All PG occurred on limbs and had typical histology with constant dermal neutrophilic infiltrate. All HS had the classical axillary-mammary phenotype. Sixty-nine percent (69%) of HS were Hurley 1 stage. Treatment consisted mainly in colchicine (n = 20), glucocorticoids (n = 12), and anti-TNFα (n = 9). Interesting results with complete or partial responses were obtained with anti-TNFα (9 cases), ustekinumab (3 cases) and tocilizumab (1 case) to treat refractory ND or HS associated with BD. CONCLUSION: PG seems overrepresented in patients with BD. Biotherapies such as anti-TNFα, ustekinumab and tocilizumab appear to be promising to treat refractory ND or HS associated with BD.

CovAID: Identification of factors associated with severe COVID-19 in patients with inflammatory rheumatism or autoimmune diseases.

Introduction: Autoimmune/inflammatory rheumatic diseases (AIRDs) patients might be at-risk of severe COVID-19. However, whether this is linked to the disease or to its treatment is difficult to determine. This study aimed to identify factors associated with occurrence of severe COVID-19 in AIRD patients and to evaluate whether having an AIRD was associated with increased risk of severe COVID-19 or death. Materials and methods: Two databases were analyzed: the EDS (Entrepôt des Données de Santé, Clinical Data Warehouse), including all patients followed in Paris university hospitals and the French multi-center COVID-19 cohort [French rheumatic and musculoskeletal diseases (RMD)]. First, in a combined analysis we compared patients with severe and non-severe COVID-19 to identify factors associated with severity. Then, we performed a propensity matched score case-control study within the EDS database to compare AIRD cases and non-AIRD controls. Results: Among 1,213 patients, 195 (16.1%) experienced severe COVID-19. In multivariate analysis, older age, interstitial lung disease (ILD), arterial hypertension, obesity, sarcoidosis, vasculitis, auto-inflammatory diseases, and treatment with corticosteroids or rituximab were associated with increased risk of severe COVID-19. Among 35,741 COVID-19 patients in EDS, 316 having AIRDs were compared to 1,264 Propensity score-matched controls. AIRD patients had a higher risk of severe COVID-19 [aOR = 1.43 (1.08-1.87), p = 0.01] but analysis restricted to rheumatoid arthritis and spondyloarthritis found no increased risk of severe COVID-19 [aOR = 1.11 (0.68-1.81)]. Conclusion: In this multicenter study, we confirmed that AIRD patients treated with rituximab or corticosteroids and/or having vasculitis, auto-inflammatory disease, and sarcoidosis had increased risk of severe COVID-19. Also, AIRD patients had, overall, an increased risk of severe COVID-19 compares general population.

Lower Relapses Rate With Infliximab Versus Adalimumab in Sight-Threatening Uveitis: A Multicenter Study of 330 Patients.

PURPOSE: To compare the relapse rate of sight-threatening noninfectious uveitis (NIU) in patients treated with infliximab (IFX) or adalimumab (ADA). DESIGN: Observational retrospective multicenter study. METHODS: A total of 330 patients (median age, 36 years; interquartile range, 27-54), 45.2% men) with sight-threatening NIU (ie, retinal vasculitis and/or macular edema) treated with anti-tumor necrosis factor [TNF]-α agents (IFX intravenously at 5 mg/kg at weeks 0, 2, 6, and every 4 to 6 weeks or ADA subcutaneously at 80 mg, then 40 mg every 2 weeks). Data were obtained retrospectively from patients' medical records. Main outcome measures were relapse rate, complete response of NIU, corticosteroid sparing effect, and safety. RESULTS: Main etiologies of uveitis included Behçet disease (27%), idiopathic juvenile arthritis (5.8%), and sarcoidosis (5.5%). The estimated relapse rate at 6 months after introduction of biological agents was 13% (95% CI = 0.009-0.16). IFX was associated with less relapse risk than ADA (hazard ratio [HR] = 0.52, 95% CI = 0.36- 0.77, P = .001). ADA and IFX were comparable in terms of complete response rate of NIU as well as corticosteroid-sparing effect. Behçet disease was associated with higher odds of complete response (HR = 2.04, 95% CI = 1.16 -3.60, P = .01] and lower relapse rate (HR = 0.53, 95% CI = 0.33-0.85, P = .009) than other causes of NIU with anti-TNF-α agents. CONCLUSIONS: In sight-threatening NIU, IFX seems to be associated with a lower relapse rate than ADA.

Prognosis Factors and Outcomes of Neuro-ophthalmologic Sarcoidosis.

BACKGROUND: Neuro-ophthalmologic manifestations are uncommon in sarcoidosis. We aim to assess the prognostic factors and outcome of neuro-ophthalmic sarcoidosis. METHODS: We conducted a multicenter retrospective study on patients with neuro-ophthalmic sarcoidosis. Response to therapy was based on visual acuity, visual field, and orbital MRI exam. Factors associated with remission and relapse were analyzed. RESULTS: Thirty-five patients [median (IQR) age of 37 years (26.5-53), 63% of women] were included. The diagnosis of sarcoidosis was concomitant of neuro-ophthalmologic symptoms in 63% of cases. Optic neuritis was the most common manifestation. All patients received corticosteroids and 34% had immunosuppressants. At 6 months, 61% improved, 30% were stable, and 9% worsened. Twenty percent of patients had severe visual deficiency at the end of follow-up. Nonresponders patients had significantly worse visual acuity at baseline (p = 0.01). Relapses were less frequent in patients with retro-bulbar optic neuropathy (p = 0.03). CONCLUSION: Prognosis of neuro-ophthalmic sarcoidosis is poor.

Anti-Tumor Necrosis Factor α versus Tocilizumab in the Treatment of Refractory Uveitic Macular Edema: A Multicenter Study from the French Uveitis Network.

PURPOSE: To analyze the factors associated with response (control of ocular inflammation and corticosteroid-sparing effect) to biologics (anti-tumor necrosis factor [TNF]-α agents and tocilizumab) in patients with refractory uveitic macular edema (ME). DESIGN: Multicenter, retrospective, observational study. PARTICIPANTS: Adult patients with uveitic ME refractory to systemic corticosteroids, disease-modifying antirheumatic drugs, or both. METHODS: Patients received anti-TNF-α agents (infliximab 5 mg/kg at week 0, 2, 6, and every 4-6 weeks [n = 69] and adalimumab 40 mg/2 weeks [n = 80]) and tocilizumab (8 mg/kg every 4 weeks intravenously [n = 39] and 162 mg/week subcutaneously [n = 16]). MAIN OUTCOME MEASURES: Analysis of complete and partial response rates, relapse rate, low vision (visual acuity in at least 1 eye of ≥ 1 logarithm of the minimum angle of resolution), corticosteroid-sparing effect, and adverse events at 6 months. RESULTS: Two hundred four patients (median age, 40 years [interquartile range, 28-58 years]; 42.2% men) were included. Main causes of uveitis included Behçet's disease (17.2%), birdshot chorioretinopathy (11.3%), and sarcoidosis (7.4%). The overall response rate at 6 months was 46.2% (21.8% of complete response) with anti-TNF-α agents and 58.5% (35.8% of complete response) with tocilizumab. In multivariate analysis, treatment with tocilizumab (odds ratio, 2.10; 95% confidence interval [CI], 1.06-4.06; P = 0.03) was associated independently with complete response of uveitic ME compared with anti-TNF-α agents. Anti-TNF-α agents and tocilizumab did not differ significantly in terms of relapse rate (hazard ratio, 1.00; 95% CI, 0.31-3.18; P = 0.99) or occurrence of low vision (odds ratio, 1.02; 95% CI, 0.51-2.07; P = 0.95) or corticosteroid-sparing effect (P = 0.29). Adverse events were reported in 20.6% of patients, including serious adverse events reported in 10.8% of patients. CONCLUSIONS: Tocilizumab seems to improve complete response of uveitic ME compared with anti-TNF-α agents.

Spectrum and Outcome of Noninfectious Aortitis.

OBJECTIVE: To assess the spectrum and long-term outcome of patients with noninfectious aortitis. METHODS: We performed a retrospective multicenter study of 353 patients (median age at diagnosis was 62 [IQR 46-71] yrs and 242 [68.6%] patients were women) with noninfectious aortitis. Factors associated with vascular complications were assessed in multivariate analysis. RESULTS: We included 136 patients with giant cell arteritis (GCA), 96 with Takayasu arteritis (TA), 73 with clinically isolated aortitis (CIA), and 48 with aortitis secondary to inflammatory diseases (including Behçet disease, relapsing polychondritis, IgG4-related disease, Cogan syndrome, ankylosing spondylitis). After a median follow-up of 52 months, vascular complications were observed in 32.3%, revascularizations in 30% of patients, and death in 7.6%. The 5-year cumulative incidence of vascular complications was 58% (95% CI 41-71), 20% (95% CI 13-29), and 19% (95% CI 11-28) in CIA, GCA, and TA, respectively. In multivariate analysis, male sex (HR 2.10, 95% CI 1.45-3.05, P < 0.0001) and CIA (HR 1.76, 95% CI 1.11-2.81, P = 0.02) were independently associated with vascular complications. CONCLUSION: Noninfectious aortitis accounts for significant morbidity and mortality. CIA seems to carry the highest rate of vascular complications.

Tuberculosis Risk Stratification of Psoriatic Patients Before Anti-TNF-α Treatment.

Psoriasis is a skin inflammatory condition for which significant progress has been made in its management by the use of targeted biological drugs. Detection of latent M. tuberculosis infection (LTBI) is mandatory before starting biotherapy that is associated with reactivation risk. Together with evaluation of TB risk factors and chest radiographs, tuberculin skin tests (TST) and/or blood interferon-γ-release assays (IGRA), like the QuantiFERON (QFT), are usually performed to diagnose M. tuberculosis infection. Using this approach, 14/49 psoriatic patients prospectively included in this study were identified as LTBI (14 TST+, induration size ≥ 10mm, 8 QFT+), and 7/14 received prophylactic anti-TB treatment, the other 7 reporting past-treatment. As the specificity and sensitivity of these tests were challenged, we evaluated the added value of an IGRA in response to a mycobacterial antigen associated with latency, the heparin-binding haemagglutinin (HBHA). All but one TST+ patient had a positive HBHA-IGRA, indicating higher sensitivity than the QFT. The HBHA-IGRA was also positive for 12/35 TST-QFT- patients. Measurement for 15 psoriatic patients (12 with HBHA-IGRA+) of 8 chemokines in addition to IFN-γ revealed a broad array of HBHA-induced chemokines for TST+QFT- and TST-QFT- patients, compared to a more restricted pattern for TST+QFT+ patients. This allowed us to define subgroups within psoriatic patients characterized by different immune responses to M. tuberculosis antigens that may be associated to different risk levels of reactivation of the infection. This approach may help in prioritizing patients who should receive prophylactic anti-TB treatment before starting biotherapies in order to reduce their number.

COVID-19 outcomes in patients with inflammatory rheumatic and musculoskeletal diseases treated with rituximab: a cohort study.

BACKGROUND: Various observations have suggested that the course of COVID-19 might be less favourable in patients with inflammatory rheumatic and musculoskeletal diseases receiving rituximab compared with those not receiving rituximab. We aimed to investigate whether treatment with rituximab is associated with severe COVID-19 outcomes in patients with inflammatory rheumatic and musculoskeletal diseases. METHODS: In this cohort study, we analysed data from the French RMD COVID-19 cohort, which included patients aged 18 years or older with inflammatory rheumatic and musculoskeletal diseases and highly suspected or confirmed COVID-19. The primary endpoint was the severity of COVID-19 in patients treated with rituximab (rituximab group) compared with patients who did not receive rituximab (no rituximab group). Severe disease was defined as that requiring admission to an intensive care unit or leading to death. Secondary objectives were to analyse deaths and duration of hospital stay. The inverse probability of treatment weighting propensity score method was used to adjust for potential confounding factors (age, sex, arterial hypertension, diabetes, smoking status, body-mass index, interstitial lung disease, cardiovascular diseases, cancer, corticosteroid use, chronic renal failure, and the underlying disease [rheumatoid arthritis vs others]). Odds ratios and hazard ratios and their 95% CIs were calculated as effect size, by dividing the two population mean differences by their SD. This study is registered with ClinicalTrials.gov, NCT04353609. FINDINGS: Between April 15, 2020, and Nov 20, 2020, data were collected for 1090 patients (mean age 55·2 years [SD 16·4]); 734 (67%) were female and 356 (33%) were male. Of the 1090 patients, 137 (13%) developed severe COVID-19 and 89 (8%) died. After adjusting for potential confounding factors, severe disease was observed more frequently (effect size 3·26, 95% CI 1·66-6·40, p=0·0006) and the duration of hospital stay was markedly longer (0·62, 0·46-0·85, p=0·0024) in the 63 patients in the rituximab group than in the 1027 patients in the no rituximab group. 13 (21%) of 63 patients in the rituximab group died compared with 76 (7%) of 1027 patients in the no rituximab group, but the adjusted risk of death was not significantly increased in the rituximab group (effect size 1·32, 95% CI 0·55-3·19, p=0·53). INTERPRETATION: Rituximab therapy is associated with more severe COVID-19. Rituximab will have to be prescribed with particular caution in patients with inflammatory rheumatic and musculoskeletal diseases. FUNDING: None.

Rituximab plus belimumab in non-infectious refractory cryoglobulinemia vasculitis: A pilot study.

OBJECTIVE: To report the efficacy of rituximab plus belimumab in patients with refractory cryoglobulinemia vasculitis (CV). METHODS: Belimumab was administered intravenously at a dose of 10 mg/kg on days 0, 14, 28 and then every month in association with rituximab in 4 patients with refractory CV. Demographic, clinical and laboratory characteristics, treatment modalities and outcomes were recorded. RESULTS: All patients had type II IgM Kappa cryoglobulinemia, which was associated with primary Sjögren syndrome (n = 1), hepatitis C virus infection (n = 1), and essential (n = 2). Main manifestations of CV included purpura (n = 4), arthralgia and peripheral neuropathy (n = 3), and glomerulonephritis and skin ulcers (n = 1). In all cases, CV was refractory and/or relapse following rituximab. Intravenous belimumab infusion along with rituximab resulted in rapid clinical response in the four patients. Osteitis and recurrent urinary tract infections occurred in two patients. CONCLUSION: Belimumab along with rituximab showed promising results in refractory patients with CV.

Biotherapies in Uveitis.

Non-infectious uveitis (NIU) represents one of the leading causes of blindness in developed countries. The therapeutic strategy aims to rapidly control intra-ocular inflammation, prevent irremediable ocular damage, allow corticosteroid sparing and save the vision, and has evolved over the last few years. Anterior NIU is mostly managed with topical treatment in adults. However, for intermediate, posterior and pan-uveitis, notably when both eyes are involved, systemic treatment is usually warranted. Biotherapies are recommended in case of inefficacy or non-tolerance of conventional immunosuppressive drugs in non-anterior NIU. Anti-tumor necrosis factor alpha (anti-TNF-α) agents are by far the most widely used, especially adalimumab (ADA) and infliximab (IFX). In case of sight-threatening uveitis in Behçet's disease or in case of risk of severe recurrences, respectively IFX and ADA may be recommended as first-line therapy. Many questions are left unanswered; how long to treat NIU, how to discontinue anti-TNF-α agents, what biologic to use in case of anti-TNF-α failure? The objective of this review is to present an updated overview of knowledge on the use of biological treatments in NIU.

Evolving spectrum of drug-induced uveitis at the era of immune checkpoint inhibitors results from the WHO's pharmacovigilance database.

PURPOSE: Drug-induced uveitis is a rare but sight-threatening condition. We seek to determine the spectrum of drug-induced uveitis at the era of immune checkpoint inhibitors (ICI). METHODS: Retrospective pharmacovigilance study based on adverse drug reactions reported within VigiBase, the WHO international pharmacovigilance database. We included deduplicated individual case safety reports (ICSRs) reported as 'uveitis' at Preferred Term level according to the Medical Dictionary for Drug Regulatory Activities between 1967 and 04/28/2019. We performed a case/non-case analysis to study if suspected drug-induced uveitis were differentially reported for each suspected treatment compared to the full database. We excluded drugs with potential indication bias. RESULTS: 1404 ICSRs corresponding to 37 drugs had a significant over-reporting signal with a median age of 57 [42-68] years and 45.7% of males. We identified five major groups of treatments: bisphosphonates (26.9%), non-antiviral anti-infectious drugs (25.4%), protein kinase inhibitors (15.5%), ICI (15.0%), and antiviral drugs (11.1%). Severe visual loss was reported in 12.1% of cases. ICI and protein kinase inhibitors were the most recently emerging signals. The time to onset between first infusion and uveitis was significantly different between groups ranging from 5 days [2-19] in the bisphosphonate group to 138.5 [47.25-263.75] in protein kinase inhibitors group (p < 0.0001). Anti-Programmed Cell death 1 represented more than 70% of ICI-induced uveitis. We identified Vogt-Koyanagi-Harada (VKH)-like syndrome as being associated with ICI use. CONCLUSIONS: The spectrum of drug-induced uveitis has changed with the evolution of pharmacopeia and the recent emergence of ICIs. VKH-like syndrome has been reported with ICI and protein kinase inhibitors therapy.

Critical role of neutrophil extracellular traps (NETs) in patients with Behcet's disease.

OBJECTIVES: Behçet's disease (BD) is a chronic systemic vasculitis. Thrombosis is a frequent and life-threatening complication. The pathogenesis of BD is poorly understood and evidence supporting a role for primed neutrophils in BD-associated thrombotic risk is scant. To respond to inflammatory insults, neutrophils release web-like structures, known as neutrophil extracellular traps (NETs), which are prothrombotic. We evaluated the role of NETs and markers of NETs in BD. METHODS: Blood samples were collected from patients with BD, according to the International Study Group Criteria for Behçet's disease, and healthy donors (HD). NET components, including cell-free DNA (CfDNA) and neutrophil enzymes myeloperoxidase (MPO), were assessed in serum or in purified neutrophils from patients with BD and HD. RESULTS: Patients with active BD had elevated serum cfDNA levels and MPO-DNA complexes compared with patients with inactive BD and to HD. In addition, levels of cfDNA and MPO-DNA complexes were significantly higher in patients with BD with vascular involvement compared with those without vascular symptoms. Purified neutrophils from patients with BD exhibited spontaneous NETosis compared with HD. Thrombin generation in BD plasma was significantly increased and positively correlated with the levels of MPO-DNA complexes and cfDNA. Importantly, DNAse treatment significantly decreased thrombin generation in BD plasma but not in HD plasma. In addition, biopsy materials obtained from patients with BD showed NETs production in areas of vasculitic inflammation and thrombosis. CONCLUSIONS: Our data show that NETs and markers of NETS levels are elevated in patients with BD and contribute to the procoagulant state. Targeting NETs may represent a potential therapeutic target for the reduction or prevention of BD-associated thrombotic risk.

Long-Term Outcome of Ustekinumab Therapy for Behçet's Disease.

OBJECTIVE: Oral ulcers, the hallmark lesion of Behçet's disease (BD), can be disabling and resistant to conventional treatment, and there is a need for safe and effective treatment. We undertook this study to investigate the long-term safety and efficacy of ustekinumab therapy for BD-related oral ulcers that are resistant to colchicine. METHODS: This multicenter, prospective, open-label study included 30 patients who fulfilled the criteria of the International Study Group for BD and who were diagnosed as having active oral ulcers resistant to colchicine. Patients were treated subcutaneously with ustekinumab 90 mg at inclusion, at week 4, and then once every 12 weeks. Each patient was assessed longitudinally for the presence and number of oral ulcers, and median numbers of oral ulcers (with interquartile range [IQR]) were calculated. The primary efficacy end point was the proportion of patients at week 12 who experienced complete response, defined as having no oral ulcers. RESULTS: The median number of oral ulcers per patient during ustekinumab therapy was significantly lower at week 12 compared to baseline (0 [IQR 0-1] versus 2 [IQR 2-3]; P < 0.0001). Complete response was achieved in 60.0% and 88.9% of patients at weeks 12 and 24, respectively. The median Behçet's Syndrome Activity Score (in which higher scores indicate more active disease) was significantly lower at weeks 12 and 24 (17.5 [IQR 10-42.5] and 10 [IQR 8-11], respectively) versus baseline (70 [IQR 50-70]; P < 0.0001). After a median follow-up of 12 months (IQR 6-16 months), 26 patients (86.7%) were still receiving ustekinumab treatment. Reasons for ustekinumab discontinuation included BD flare (n = 3) and side effects (n = 1). Seven patients (23.3%) experienced adverse events, including headaches (n = 4) and asthenia (n = 2), with no serious side effects. CONCLUSION: Ustekinumab seems to be effective in treating BD-related oral ulcers that are resistant to treatment with colchicine.

Corticosteroids and immunosuppressive agents for idiopathic recurrent pericarditis.

Recurrent pericarditis is a frequent and troublesome complication of acute pericarditis. Aspirin or non-steroidal anti-inflammatory drugs (NSAIDs) and colchicine are the mainstay of therapy but few data is available on second-line treatment. We retrospectively analyzed 13 patients, 7 females (54%), median age 40 years, with a median of 4 (IQR 1-6) recurrences per patient despite a well conducted first-line treatment and a median follow-up of 59 months (IQR 38-70). Ten patients received corticosteroids as second-line therapy; 6 out of 10 responded to this therapy while 4 needed the addition of azathioprine. Three other patients received an immunosuppressive agent as second-line therapy (azathioprine, methotrexate, mycophenolate mofetyl). Overall, the mean frequency per month (± SD) of pericarditis recurrences was 0.69 (± 0.40) with aspirin/NSAIDs and colchicine, 0.22 (± 0.34) with corticosteroids alone and 0.01 (± 0.04) with immunosuppressive agents (p < 10-4). Immunosuppressive agents including azathioprine, methotrexate and mycophenolate mofetyl seem efficacious and well tolerated in patients with idiopathic recurrent pericarditis unresponsive to corticosteroids, corticosteroids-dependent or when corticosteroids side effects are judged unacceptable.

Neuro-ophthalmological manifestations of Behçet's disease.

BACKGROUND: The neuro-ophthalmological manifestations of Behcet's disease (BD) are rare, and data regarding their characteristics and outcome are lacking. OBJECTIVE: To report prevalence, main characteristics and outcome of neuro-ophthalmological manifestations in BD. PATIENTS AND METHODS: This is a retrospective monocentric study of 217 patients diagnosed with neuro-Behçet's disease (NBD), of whom 29 (13.3%) patients presented with neuro-ophthalmological manifestations (55% of men and mean±SD age of 26±8 years). All patients underwent a detailed ophthalmological examination and were followed up in the internal medicine and the ophthalmology departments. RESULTS: Neuro-ophthalmological manifestations were the first presentation of BD in 45% of patients and developed later in the course of the disease in 55% of patients. They are divided into parenchymal (PM) and non-parenchymal (NPM)-related manifestations in, respectively, 13 patients (45%) and 16 patients (55%). PM included papillitis in seven patients (53.8%), retrobulbar optic neuritis in four patients (30.8%) and third cranial nerve palsy in two patients (15.4%). NPM included papilloedema related to cerebral venous thrombosis in all 16 patients, of whom 6 patients (37.5%) had sixth cranial nerve palsy. At initial examination, 93.1% of patients had visual alterations, including mainly decreased visual acuity visual field defects and/or diplopia. All patients were treated with corticosteroids and 79% of patients received immunosuppressive agents. After treatment, the visual outcome improved or stabilised in 66.7% of patients while it worsened in 33.3. The mean±SD logarithm of the minimum angle of resolution visual acuity improved from 0.4±0.3 at diagnosis to 0.2±0.3 after therapy. 10.3% and 3.4% of patients were legally blind at diagnosis and after therapy, respectively. CONCLUSION: Neuro-ophthalmological manifestations of BD represented 13% of NBD. They could be potentially severe and disabling. Prompt treatment is the key factor in improving visual outcome.

Sarcoidosis with Takayasu arteritis: a model of overlapping granulomatosis. A report of seven cases and literature review.

OBJECTIVE: To describe the features of exceptional coexisting Takayasu arteritis (TA) and sarcoidosis, two conditions of unknown cause associated with a common immunologic pattern. METHODS: We report seven cases of concomitant sarcoidosis-Takayasu or Takayasu-like vasculitis, observed in two referral centers between 1995 and 2015. RESULTS: All patients were female. The mean age at sarcoidosis diagnosis and TA diagnosis was 36 and 37 years, respectively. Sarcoidosis occurred in 86% of cases before or together with TA. Sarcoidosis always had a classic expression except for one renal localization. Sarcoidosis was not severe and mostly non-treated (86%). In all cases of TA, supra-aortic arteries were involved; in only two TA cases a more diffuse inflammatory arterial involvement was noted. In one case, Takayasu arteritis occurred despite immunosuppressive therapy given for sarcoidosis. All patients received for TA a treatment with corticosteroids associated with methotrexate (four cases), infliximab (one case) or tocilizumab (one case). After a mean follow-up of 89 months, TA always improved and no death was observed. CONCLUSIONS: TA stands as pathology associated with sarcoidosis. TA occurred in three cases among 50. When sarcoidosis preceded TA, a recovery of sarcoidosis was achieved mostly without treatment. TA is a prognostic and therapeutic factor. Immunosuppressive treatment, including steroids, led to a good prognosis for TA as well as for sarcoidosis.
