ANCA-associated scleritis: impact of ANCA on presentation, response to therapy and outcome.

OBJECTIVES: To describe the characteristics, treatment and outcome of isolated ANCA-associated scleritis at diagnosis compared with idiopathic scleritis with negative ANCA tests. METHODS: This retrospective multicentre case-control study was performed within the French Vasculitis Study Group (FVSG) network and in three French tertiary ophthalmologic centres. Data from patients with scleritis without any systemic manifestation and with positive ANCA results were compared with those of a control group of patients with idiopathic scleritis with negative ANCA tests. RESULTS: A total of 120 patients, including 38 patients with ANCA-associated scleritis and 82 control patients, diagnosed between January 2007 and April 2022 were included. The median follow-up was 28 months (IQR 10-60). The median age at diagnosis was 48 years (IQR 33-60) and 75% were females. Scleromalacia was more frequent in ANCA-positive patients (P = 0.027) and 54% had associated ophthalmologic manifestations, without significant differences. ANCA-associated scleritis more frequently required systemic medications, including glucocorticoids (76% vs 34%; P < 0.001), and rituximab (P = 0.03) and had a lower remission rate after the first- and second-line treatment. Systemic ANCA-associated vasculitis (AAV) occurred in 30.7% of patients with PR3- or MPO-ANCA, after a median interval of 30 months (IQR 16.3-44). Increased CRP >5 mg/l at diagnosis was the only significant risk factor of progression to systemic AAV [adjusted hazard ratio 5.85 (95% CI 1.10, 31.01), P = 0.038]. CONCLUSION: Isolated ANCA-associated scleritis is mostly anterior scleritis with a higher risk of scleromalacia than ANCA-negative idiopathic scleritis and is more often difficult to treat. One-third of patients with PR3- or MPO-ANCA scleritis progressed to systemic AAV.

BOB-ACG study: Pulse methylprednisolone to prevent bilateral ophthalmologic damage in giant cell arteritis. A multicentre retrospective study with propensity score analysis.

INTRODUCTION: Giant cell arteritis (GCA) is complicated in 10 to 20% of cases by permanent visual ischemia (PVI). International guidelines advocate the use of intravenous pulse of methylprednisolone from 250 to 1000mg per day, for three days, followed by oral prednisone at 1mg/kg per day. The aim of this study is to assess whether this strategy significantly reduces the risk of early PVI of the second eye, compared with direct prednisone at 1mg/kg per day. METHODS: We conducted a multicentre retrospective observational study over the past 15 years in 13 French hospital centres. Inclusion criteria included: new case of GCA; strictly unilateral PVI, prednisone at dose greater than or equal to 0.9mg/kg per day; for the intravenous methylprednisolone (IV-MP) group, total dose between 900 and 5000mg, close follow-up and knowledge of visual status at 1 month of treatment, or earlier, in case of contralateral PVI. The groups were compared on demographic, clinical, biological, iconographic, and therapeutic parameters. Statistical analysis was optimised using propensity scores. RESULTS: One hundred and sixteen patients were included, 86 in the IV-MP group and 30 in the direct prednisone group. One patient in the direct prednisone group and 13 in the IV-MP group bilateralised, without significant difference between the two strategies (3.3% vs 15.1%). Investigation of the association between IV-MP patients and contralateral PVI through classical logistic regression, matching or stratification on propensity score did not show a significant association. Weighting on propensity score shows a significant association between IV-MP patients and contralateral PVI (OR=12.9 [3.4; 94.3]; P<0.001). Improvement in visual acuity of the initially affected eye was not significantly associated with IV-MP (visual acuity difference 0.02 vs -0.28 LogMar), even in the case of early management, i.e., within the first 48hours after the onset of PVI (n=61; visual acuity difference -0.11 vs 0.25 LogMar). Complications attributable to corticosteroid therapy in the first month were significantly more frequent in the IV-MP group (31.8 vs 10.7%; P<0.05). DISCUSSION: Our data do not support the routine use of pulse IV-MP for GCA complicated by unilateral PVI to avoid bilateral ophthalmologic damage. It might be safer to not give pulse IV-MP to selected patients with high risks of glucocorticoids pulse side effects. A prospective randomised multicentre study comparing pulse IV-MP and prednisone at 1mg/kg per day is desirable.

Prognostic factors in giant cell arteritis associated aortitis with PET/CT and CT angiography at diagnosis.

BACKGROUND: Prognosis data on giant-cell arteritis (GCA)-associated aortitis are scarce and heterogeneous. The aim of this study was to compare the relapses of patients with GCA-associated aortitis according to the presence of aortitis on CT-angiography (CTA) and/or on FDG-PET/CT. METHODS: This multicenter study included GCA patients with aortitis at diagnosis; each case underwent both CTA and FDG-PET/CT at diagnosis. A centralized review of image was performed and identified patients with both CTA and FDG-PET/CT positive for aortitis (Ao-CTA+/PET+); patients with positive FDG-PET/CT but negative CTA for aortitis (Ao-CTA-/PET+), and patients solely positive on CTA. RESULTS: Eighty-two patients were included with 62 (77%) of female sex. Mean age was 67±8 years; 64 patients (78%) were in the Ao-CTA+/PET+ group; 17 (22%) in the Ao-CTA-/PET+ group and 1 had aortitis only on CTA. Overall, 51 (62%) patients had at least one relapse during follow-up: 45/64 (70%) in the Ao-CTA+/PET+ group and 5/17 (29%) in the Ao-CTA-/PET+ group (log rank, p = 0.019). In multivariate analysis, aortitis on CTA (Hazard Ratio 2.90, p = 0.03) was associated with an increased risk of relapse. CONCLUSION: Positivity of both CTA and FDG-PET/CT for GCA-related aortitis was associated with an increased risk of relapse. Aortic wall thickening on CTA was a risk factor of relapse compared with isolated aortic wall FDG uptake.

Atypical Case of MOG Antibody-Associated Optic Neuritis with Roth Spots.

PURPOSE: To report an atypical case of MOG antibody-associated optic neuritis with Roth spots and widespread retinal hemorrhages. CASE REPORT: A 49-year-old woman complained of 1 week history painful visual loss in the left eye. Funduscopy exam showed a severe optic disc edema associated with multiple peripapillar hemorrhages, peripheral retinal hemorrhages and Roth spots in the left eye. Orbit MRI revealed an hyperintensity in the left optic nerve, enhanced with gadolinium. The serum Myelin Oligodendrocyte (MOG) antibodies was found positive. Early intravenous high dose of steroids rapidly improved visual acuity and fundus abnormalities rapidly resolved. CONCLUSION: Retinal hemorrhages can also be detected in case of optic disc edema associated with an optic neuritis, as seen in MOGAD.

Treatment of nonarteritic anterior ischemic optic neuropathy with an endothelin antagonist: ENDOTHELION (ENDOTHELin antagonist receptor in Ischemic Optic Neuropathy)-a multicentre randomised controlled trial protocol.

BACKGROUND: Nonarteritic anterior ischemic optic neuropathy (NAAION) is a major cause of blindness in individuals over 50 years of age, with no available effective treatment. The oral dual endothelin receptor antagonist, bosentan, increases retinal optic nerve head blood flow in healthy humans and glaucoma patients. The objective of this trial is to assess the efficacy of bosentan administered at the acute stage in improving outcomes in NAAION patients. METHODS: ENDOTHELION (ENDOTHELin antagonist receptor in Ischemic Optic Neuropathy) is a phase III, interventional, prospective, multicentre, placebo-controlled randomised double-blind clinical trial. The primary outcome is change in the visual field mean deviation (MD) at 3 months (Humphrey 30-2 SITA standard programme). Secondary outcomes include MD and visual acuity changes up to 24 months, changes in peripapillary retinal nerve fibre and macular ganglion cell layer thickness in the affected eye, as measured by optical coherence tomography, rate of NAAION bilateralisation at 2 years, and quality-of-life. Patients over 50 years of age presenting with typical NAAION of recent onset (less than 21 days) are randomly assigned to either 125 mg oral bosentan or placebo, twice a day, during 8 weeks. Besides visits during the treatment phase, patients attend follow-up visits at 2, 3, 6, 12 and 24 months. The inclusion of patients began in August 2015 at five French University hospital ophthalmology departments and two specialised ophthalmology centres. It is planned to include 86 patients in this trial. To date we have included 72 patients and 49 have completed the full follow-up process. DISCUSSION: An endothelin receptor antagonist is a potential approach to improving the anatomical and functional prognosis of patients with NAAION. This multicentre double-blind randomised controlled trial is an opportunity to assess (1) the effect of bosentan on the structure and function of the optic nerve in NAAION, at 3 months, (2) the effect of bosentan on the bilateralisation rate at 24 months and (3) the tolerance profile of bosentan in this population. TRIAL REGISTRATION: ClinicalTrials.gov NCT02377271 . Registered on March 3, 2015.

Ocular Complications of Giant Cell Arteritis: An Acute Therapeutic Emergency.

The risk of blindness, due to acute ischemic ocular events, is the most feared complication of giant cell arteritis (GCA) since the middle of the 20th century. A decrease of its rate has occurred after the advent of corticoid therapy for this vasculitis, but it seems to have stabilized since then. Early diagnosis and treatment of GCA is key to reducing its ocular morbidity. However, it is not uncommon for ophthalmological manifestations to inaugurate the disease, and the biological inflammatory reaction may be mild, making its diagnosis more challenging. In recent years, vascular imaging has opened up new possibilities for the rapid diagnosis of GCA, and ultrasound has taken a central place in fast-track diagnostic processes. Corticosteroid therapy remains the cornerstone of treatment and must begin immediately in patients with visual symptoms and suspicion of GCA. In that situation, the administration route of corticotherapy, intravenous or oral, is less important than its speed of delivery, any hour of delay worsening the prognosis.

Hidden in the Eyes-Recurrence of Systemic Hemopathies Reportedly "In Remission": Six Cases and Review of Literature.

Background and Objectives: Secondary ocular localizations of hematological malignancies are blinding conditions with a poor prognosis, and often result in a delay in the diagnosis. Materials and Methods: We describe a series of rare cases of ocular involvement in six patients with hematological malignancies, reportedly in remission, who presented secondary ocular localizations, challenging to diagnose. Two patients had an acute lymphoblastic leukemia (ALL) and developed either a posterior scleritis or a pseudo-panuveitis with ciliary process infiltration. One patient had iris plasmacytoma and developed an anterior uveitis as a secondary presentation. Two patients had a current systemic diffuse large B-cell lymphoma (DLBCL) and were referred either for intermediate uveitis or for papilledema and vitritis with secondary retinitis. Finally, one patient with an acute myeloid leukemia (AML) presented a conjunctival localization of a myeloid sarcoma. We herein summarize the current knowledge of ophthalmologic manifestations of extramedullary hematopathies. Results: Inflammatory signs were associated with symptomatic infiltrative lesions well displayed in either the iris, the retina, the choroid, or the cavernous sinus, from the admission of the patients in the ophthalmological department. These findings suggest that patients with ALL, AML, systemic DLBCL, and myeloma can present with ophthalmic involvement, even after having been reported as in remission following an effective systemic treatment and/or allograft. Conclusions: Early detection of hidden recurrence in the eyes may permit effective treatment. Furthermore, oncologists and ophthalmologists should be aware of those rare ocular malignant locations when monitoring patient's progression after initial treatment, and close ophthalmologic examinations should be recommended when detecting patient's ocular symptoms after treatment.

Cytokines, chemokines and growth factors profile in human aqueous humor in idiopathic uveitis.

To investigate which cytokines, chemokines and growth factors are involved in the immunopathogenesis of idiopathic uveitis, and whether cytokine profiles are associated with. Serum and aqueous humor (AH) samples of 75 patients with idiopathic uveitis were analyzed by multiplex immunoassay. Infectious controls consisted of 16 patients with ocular toxoplasmosis all confirmed by intraocular fluid analyses. Noninfectious controls consisted of 7 patients with Behçet disease related uveitis and 15 patients with sarcoidosis related uveitis. The control group consisted of AH and serum samples from 47 noninflammatory control patients with age-related cataract. In each sample, 27 immune mediators ± IL-21 and IL-23 were measured. In idiopathic uveitis, 13 of the 29 mediators, including most proinflammatory and vascular mediators such as IL-6, IL-8, IL-12, G-CSF, GM-CSF, MCP-1, IP-10, TNF-α and VEGF, were significantly elevated in the aqueous humor when compared to all controls. Moreover, IL-17, IP-10, and IL-21, were significantly elevated in the serum when compared to all controls. We clustered 4 subgroups of idiopathic uveitis using a statistical analysis of hierarchical unsupervised classification, characterized by the order of magnitude of concentrations of intraocular cytokines. The pathogenesis of idiopathic uveitis is characterized by the presence of predominantly proinflammatory cytokines and chemokines and vascular endothelial growth factor with high expression levels as compared to other causes of uveitis. There are indications for obvious Th-1/ IL21-Th17 pathways but also IL9-Th9 and increased IFN-γ-inducing cytokine (IL12) and IFN-γ-inducible CXC chemokine (IP-10). The combined data suggest that immune mediator expression is different among idiopathic uveitis. This study suggests various clusters among the idiopathic uveitis group rather than one specific uveitis entity.

Tocilizumab versus Rituximab in Patients with Moderate to Severe Steroid-resistant Graves' Orbitopathy.

INTRODUCTION: To describe the efficacy of tocilizumab in patients with Graves' orbitopathy resistant or dependent to steroids and compare to rituximab treated patients. PATIENTS AND METHODS: Graves's orbitopathy response was considered as decrease of at least 2 points of the CAS. RESULTS: Twenty-one patients were included, 7 patients were treated with tocilizumab and 14 with rituximab. The primary was achieved in all 7 patients (100%) on tocilizumab and 9 out of 14 patients on (64%) rituximab (p = .17). Mean change in CAS was consistent with a decrease of 3.3 ± 0.5 points in patients on tocilizumab versus 2.5 ± 1.9 in patients on rituximab (p = .07). One patient on tocilizumab (14%) and 4 patients (29%) on rituximab experienced significant relapse during the follow-up. The difference in relapse-free survival was not significant in patients on tocilizumab (10.8 ± 4 months) compared with rituximab (17.88 ± 3.66). CONCLUSION: We showed a significant improvement in the CAS, visual acuity, diplopia, and proptosis with both tocilizumab and rituximab.

Review of the Current Literature and Our Experience on the Value of OCT-angiography in White Dot Syndromes.

PURPOSE: To describe the application of OCT-A in various posterior uveitis disorders in our experience and to compare it with the available literature. METHODS: Eighteen eyes with the diagnoses of multifocal choroiditis (MFC), multifocal placoid pigment epitheliopathy (APMPPE), multiple evanescent white dot syndrome (MEWDS), tuberculous serpiginous-like choroiditis (SLC), serpiginous choroiditis (SC), and birdshot chorioretinopathy (BSCR) were studied. RESULTS: We found flow void of the choriocapillaris in patients with APMPPE, SC, MFC, BSCR, and in SLC. In contrast, perfusion of the choriocapillaris seemed normal in patients with MEWDS. CONCLUSIONS: We confirmed that OCT-A contributes new information on the physiopathology of white dot syndromes and inflammatory chorioretinopathies, notably on whether or not the choriocapillaris is involved. Comparing the OCT-A features allowed us to suggest that both APMPPE and SLC might be part of the same spectrum of inflammatory disease with primary involvement at the level of the choriocapillaris and secondary RPE damage.

Presentation and Real-World Management of Giant Cell Arteritis (Artemis Study).

Background: Few studies of daily practice for patients with giant cell arteritis (GCA) are available. This French study aimed to describe the characteristics and management of GCA in a real-life setting. Methods: Cross-sectional, non-interventional, multicenter study of patients ≥50 years old who consulted hospital-based specialists for GCA and were under treatment. Patient characteristics and journey, diagnostic methods and treatments were collected. Descriptive analyses were performed. Results: In total, 306 patients (67% females, mean age 74 ± 8 years old) were recruited by 69 physicians (internists: 85%, rheumatologists: 15%); 13% of patients had newly diagnosed GCA (diagnosis-to-visit interval <6 weeks). Overall median disease duration was 13 months (interquartile range 5-26). Most patients were referred by general practitioners (56%), then ophthalmologists (10%) and neurologists (7%). Most common comorbidities were hypertension (46%), psychiatric disorders (10%), dyslipidemia (12%), diabetes (9%), and osteoporosis (6%). Initial GCA presentations included cranial symptoms (89%), constitutional symptoms (74%), polymyalgia rheumatica (48%), and/or other extra-cranial manifestations (35%). Overall, 85, 31, 26, and 30% of patients underwent temporal artery biopsy, high-resolution temporal artery Doppler ultrasonography, 18FDG-PET, and aortic angio-CT, respectively. All patients received glucocorticoids, which were ongoing for 89%; 29% also received adjunct medication(s) (methotrexate: 19%, tocilizumab: 15%). A total of 40% had relapse(s); the median time to the first relapse was 10 months. Also, 37% had comorbidity(ies) related to or aggravated by glucocorticoids therapy. Conclusion: This large observational study provides insight into current medical practices for GCA. More than one third of patients had comorbidities related to glucocorticoid therapy for a median disease duration of 13 months. Methotrexate and tocilizumab were the most common adjunct medications.

The brainstem in multiple sclerosis: MR identification of tracts and nuclei damage.

OBJECTIVE: To evaluate the 3D Fast Gray Acquisition T1 Inversion Recovery (FGATIR) sequence for MRI identification of brainstem tracts and nuclei damage in multiple sclerosis (MS) patients. METHODS: From april to december 2020, 10 healthy volunteers and 50 patients with remitted-relapsing MS (58% female, mean age 36) underwent MR imaging in the Neuro-imaging department of the C.H.N.O. des Quinze-Vingts, Paris, France. MRI was achieved on a 3 T system (MAGNETOM Skyra) using a 64-channel coil. 3D FGATIR sequence was first performed on healthy volunteers to classify macroscopically identifiable brainstem structures. Then, FGATIR was assessed in MS patients to locate brainstem lesions detected with Proton Density/T2w (PD/T2w) sequence. RESULTS: In healthy volunteers, FGATIR allowed a precise visualization of tracts and nuclei according to their myelin density. Including FGATIR in MR follow-up of MS patients helped to identify structures frequently involved in the inflammatory process. Most damaged tracts were the superior cerebellar peduncle and the transverse fibers of the pons. Most frequently affected nuclei were the vestibular nuclei, the trigeminal tract, the facial nerve and the solitary tract. CONCLUSION: Combination of FGATIR and PD/T2w sequences opened prospects to define MS elective injury in brainstem tracts and nuclei, with particular lesion features suggesting variations of the inflammatory process within brainstem structures. In a further study, hypersignal quantification and microstructure information should be evaluated using relaxometry and diffusion tractography. Technical improvements would bring novel parameters to train an artificial neural network for accurate automated labeling of MS lesions within the brainstem.

Evaluating the cost-consequence of a standardized strategy for the etiological diagnosis of uveitis (ULISSE study).

MAIN OBJECTIVE: To prospectively assess the cost-consequence of a standardized diagnostic strategy as to compared to an open one for the etiological diagnosis of uveitis. DESIGN: This was a prospective, non-inferiority, multicentre, randomized controlled trial. METHODS: We included all consecutive patients with uveitis who had visited at least one of the Departments of Ophthalmology. In the standardized group, patients had a minimal work-up regardless of the type of uveitis (including evaluation of the CBC, ESR, C-reactive protein, tuberculin skin test, syphilis serology and chest X-ray). Depending on ophthalmological findings, further investigations could be performed. In the open strategy, ophthalmologists were free to order any kind of investigation. The main outcome was the mean cost per patient of each strategy. RESULTS: 903 uveitis patients were included from January, 2010 to May, 2013. The mean cost per patient of the standardized strategy was 182.97 euros [CI 95% (173.14; 192.80)], and the mean cost per patient of the open strategy was 251.75 euros [CI 95% (229.24; 274.25)]. Therefore, the mean cost per patient of the standardized strategy was significantly lower than the mean cost per patient of the open strategy (p<0.001). There were significantly fewer visits (p<0.001), fewer radiological procedures (p<0.004) and fewer laboratory investigations (p<0.001) in the standardized group. CONCLUSION: A standardized strategy is a cost-saving approach for the etiological diagnosis of uveitis.

Low-Dose Rituximab for Active Moderate to Severe Graves' Orbitopathy Resistant to Conventional Treatment.

Purpose: To report low-dose rituximab effect in Graves' orbitopathy (GO) resistant to conventional treatment. Methods: Retrospective analysis of medical records, filled in according to the European Group on Graves' Orbitopathy (EUGOGO) standards, of patients with active moderate-to-severe GO who received low-dose rituximab after failure of conventional treatment. Efficacy was defined by a decrease of the clinical activity score of 2 points or <4/10. Results: Among 219 patients treated between 2012 and 2016 by pulse methylprednisolone, possibly followed by oral steroids and/or orbital radiotherapy, 15 (6.8%) finally received 100 mg rituximab doses (cumulative dose, 100-400 mg) owing to persistent active disease. Rituximab showed efficacy within 2 months in 13 of 15 (87%), stable at 1 year. No significant effect was observed on proptosis, lid fissure width, and eye motility. Conclusion: Low-dose rituximab showed sustained anti-inflammatory effect in most patients with active GO resistant to conventional treatment.

A Comparison of the Dexamethasone Implant (Ozurdex®) and Inferior Fornix-Based Sub-Tenon Triamcinolone Acetonide for Treatment of Inflammatory Ocular Diseases.

PURPOSE: To evaluate the efficacy and safety of dexamethasone (DEX) implant compared with inferior fornix-based sub-Tenon triamcinolone injection (PSTA) for treatment of uveitis. METHODS: A total of 48 eyes received DEX and 49 eyes received PSTA as the first treatment. RESULTS: A total of 31 eyes were implanted with DEX relapsed (64.5%) after the first injection, while 32 eyes were injected with PSTA as the first treatment relapsed (65.3%). Kaplan-Meier estimated survival to overall relapse after the first injection was a mean 20 months± 3.6 months for DEX (median,7) and 14 months± 1.9 months (median,9) for the PSTA (P = 0.505). Of 49 eyes receiving the PSTA implant as the first treatment, inflammation persisted in 14.3% after the first injection but persisted in none after the DEX injection (P = 0.005). CONCLUSIONS: DEX implantation achieved a higher rate of disease control in the initial 12 weeks postinjection with a relative equivalence in the duration of effect and relapse rates when compared with PSTA.

IgG4-related disease in patients with idiopathic orbital inflammation syndrome: data from the French SIOI prospective cohort.

PURPOSE: To better characterize IgG4-related disease (RD) in the setting of idiopathic orbital inflammation syndrome (IOIS). METHODS: National, multicentre, prospective, observational cohort study. Among the patients consecutively included in the French multicentre SIOI cohort, we selected those who underwent orbital and/or adnexal biopsy. Clinical, morphological and pathological findings at diagnosis were blindly analysed. Serum IgG4 levels at inclusion were measured and all available biopsy specimens were immunostained for IgG4 and IgG. Biopsy samples with more than 10 IgG4-positive plasma cells per high-power field and a IgG4+/IgG+ plasma cell ratio above 40% were scored as positive. IgG4-positive patients were then screened for comprehensive diagnostic criteria for IgG4-RD. RESULTS: Of the 87 patients included, 35 had histologically documented IOIS. Thirteen patients (37%) with a mean age at onset of 27 years (range 21-78) had IgG4-positive biopsies, among which 10 patients (77%) and 3 (23%, with IgG4 serum levels >1.35 g/L) were considered as having probable and definite IgG4-RD, respectively. The latter 13 patients more frequently fulfilled histological criteria for IgG4-RD (including plasmacytic infiltrate (p = 0.006), fibrosis (p = 0.0025) and periphlebitis (p = 0.075)) than IgG4-negative patients. Storiform fibrosis was exclusively found in orbital tissues from IgG4-positive patients (n = 3, 23%). Eosinophilia associated with recurrent sinusitis or asthma was a prominent feature in patients with definite IgG4-RD. CONCLUSIONS: More than one-third of patients with biopsy-proven IOIS satisfied criteria for IgG4-RD, but only a few had a definite type.

Contribution of diagnostic tests for the etiological assessment of uveitis, data from the ULISSE study (Uveitis: Clinical and medicoeconomic evaluation of a standardized strategy of the etiological diagnosis).

PURPOSE: ULISSE is the only study that prospectively assessed the efficiency of a standardized strategy, compared to an open strategy for the etiologic diagnosis of uveitis. Our aim was to evaluate the diagnostic yield of the tests prescribed in the ULISSE study to clarify their relevance. METHODS: ULISSE is a non-inferiority, prospective, multicenter and cluster randomized study. The standardized strategy is a two-steps strategy: in the first step, common standard tests were performed, and in the second step, tests were guided by the clinical and anatomic type of uveitis. We reported the relevance of the diagnostic tests used in the standardized strategy, as well as the profitability of the tests that were prescribed to more than twenty patients in each group. Based on diagnostic criteria, either an ophthalmologist, or an internist, established the profitability of a test by considering whether the test lead to a diagnosis or not. RESULTS: Among the 676 patients included (standardized 303; open 373), a diagnosis was made for 152 (50.4%) in the standardized group and 203 (54.4%) in the open group. The most common entities were HLA-B27 associated uveitis (22%), spondyloarthritis (11%), sarcoidosis (18%), tuberculosis (10.7%) and herpes virus infections (8.5%). Among the first step's systematic tests, tuberculin skin test was the most contributive investigation (17.1%), followed by chest X-ray (8.4%), C reactive protein and ESR (6.6% and 5.1%), complete blood count (2.2%) and VDRL (2.0%). The second step's most often contributive tests were: HLA B27 (56.3%), chest-CT (30.3%) and angiotensin converting enzyme (ACE) (16.5%). HLA B27 and ACE were significantly more contributive in the standardized group than in the open group. Immunological tests were never contributive. Among the free investigations, or among the investigations guided by clinical or paraclinical findings, the most often contributive tests were: Quantiferon® (24%), electrophoresis of serum protein (7.8%) and sacroiliac imagery (46.4%). Intracellular serologies (1.7%), serum calcium (2.1%) and hepatic tests (3.3%) were exceptionally contributive. Among the third intention tests, labial salivary gland biopsies were contributive in 17.9% of cases, but the profitability of other invasive investigations (anterior chamber tap, vitrectomy, bronchoscopy and lumbar puncture) or specialized imagery (18F-FDG PET, Brain MRI) could not be determined since these test were rarely performed. CONCLUSION: Only a few diagnostic tests are useful for the etiological assessment of uveitis. They are often cheap, simple, more often guided by the clinical findings, and lead to an etiological diagnosis in most patients. On the other hand, some tests are never or exceptionally contributive, such as immunological tests or intracellular serologies. Further studies are required to evaluate the profitability of third intention imagery and invasive investigations.

Increase in Ocular Syphilis Cases at Ophthalmologic Reference Center, France, 2012-2015.

We describe the frequency, demographic and clinical features, and visual outcomes of ocular syphilis infections observed during 2012-2015 at a tertiary reference center in Paris, France. Twenty-one cases (29 eyes) were identified. The occurrence of ocular syphilis increased from 1 case in 2012 to 5 cases in 2013, 6 cases in 2014, and 9 cases in 2015 (2.22-25.21/1,000 individual patients/year for the period). Among case-patients, an annual 20%-33% were co-infected with HIV. Seventy-six percent of ocular syphilis infections occurred in men who have sex with men. Seventy-five percent of case-patients had a good final visual outcome (best-corrected visual acuity >0.3 logMAR score). Visual outcome was worse for HIV-positive patients than for HIV-negative patients (p = 0.0139). At follow-up, the best visual outcomes were observed in patients whose mean time from first ocular symptom to consultation was 15 days (SD +19 days).

Prognostic Factors in Syphilitic Uveitis.

PURPOSE: To identify predictors of treatment success in syphilitic uveitis (SU). DESIGN: Retrospective multicentric analysis of patients treated for SU. PARTICIPANTS: A total of 95 eyes (66 patients, mean [standard deviation] aged 49 [12.5] years, 31 [47%] of whom were human immunodeficiency virus [HIV]+) were analyzed. METHODS: Activity of SU was assessed at 1 week and 1 month after treatment onset, and at last follow-up. Improvement was defined by a ≥2-step decrease of both anterior chamber and vitreous haze inflammation levels, and by the size reduction in chorioretinal lesions. MAIN OUTCOME MEASURES: Recovery was defined as the resolution of inflammation in all anatomic structures at 1 month. RESULTS: Panuveitis and posterior uveitis were the most frequent findings. Inflammatory parameters were higher in HIV+ patients. Recovery was reported in 65% and 85% of eyes at 1 month and at last follow-up, respectively. In multivariate analysis, after adjusting for initial best-corrected visual acuity and the antimicrobial treatment regimen, clinical improvement at 1 week (corrected risk ratios [cRR], 3.5 [2.3-3.8]; P = 0.001) was predictive of recovery at 1 month, whereas the use of periocular dexamethasone injections (cRR, 0.05 [0.02-0.6]; P = 0.01) and methylprednisolone pulses negatively affected the outcomes of eyes. CONCLUSIONS: Early improvement is the strongest predictor of ophthalmological recovery in SU.
