RESUMO

Macrophage-like cells (MLC) have a fundamental role in the maintenance of immunosurveillance, response to inflammation and tissue injury in the retina. MLC can be visualized in vivo with conventional en face optical coherence tomography (OCT). The aim of this study is to describe this population of cells in active toxoplasmosis. We present two cases of active toxoplasma retinochoroiditis imaged at 2 time points, where the MLC were threshold after image processing and averaging for removing background and noise. In both patients the MLC collocated with the area of ischemia at the level of the choriocapillaris and retinal vessels.

RESUMO

PURPOSE: This study assessed the effectiveness of the 0.19-mg fluocinolone acetonide (FAc) implant by multimodal measurements in patients with non-infectious uveitis (NIU) in a real-world setting in Spain. METHODS: A prospective study of patients who had NIU including uveitic macular oedema (UME) with ≥ 12 months follow-up was done. Exclusion criteria include infectious uveitis and uncontrolled glaucoma or ocular hypertension requiring more than 2 medications. Effectiveness was assessed using a multicomponent outcome measure that included nine outcomes. Effectiveness was defined as all components being met at every timepoint. Secondary outcome measures were onset or progression of glaucoma and investigator-reported adverse events. RESULTS: Twenty-six eyes from 22 patients were included, with 96.2% having an indication including UME. During the 12-month study, the FAc implant was effective in 15 (57.7%) eyes, reaching effectiveness as soon as 2 weeks post-implantation. Mean best-corrected visual acuity and mean central macular thickness (CMT) were significantly improved vs. baseline at all timepoints (all comparisons p < 0.01). During the 12-month study, inflammation markers (anterior chamber cells and vitreous haze) had also significantly declined. Factors predicting effectiveness at month 12 were systemic corticosteroid dose pre-FAc, higher immunomodulatory therapy (IMT) load at baseline and thicker retinal nerve fibre layer (RNFL) at baseline (all p < 0.05). Factors predicting failure were male gender, thinner RNFL at baseline and treatment ineffectiveness at 1 month (all p < 0.05). In parallel, corticosteroid and IMT use also declined significantly. No significant increase in IOP was detected. CONCLUSION: The FAc implant is safe and effective at treating NIU over 12 months in a real-world setting in Spain.

RESUMO

AIMS: To evaluate the clinical characteristics and therapeutic outcome of patients with recurrent scleritis of unknown demonstrable aetiology and positive QuantiFERON-TB Gold In-Tube test (QFT). METHODS: Retrospective chart review of the demographic, clinical, laboratory and therapeutic outcome data of 15 patients. Clinical characteristics as well as remission rate after standard antituberculous therapy (ATT) were assessed. RESULTS: There were 9 men and 6 women with a mean age of 48.9 years (range, 32-73). Scleritis was diffuse in 10 patients (66.6%) and nodular in 5 patients (33.3%), 1 of them with concomitant posterior scleritis. It was bilateral in 7 patients (46.6%) and recurrent in all of them. Scleritis appeared after prior uveitis (10 patients, 66.6%) and/or with concomitant uveitis (5 patients, 33.3%) or peripheral keratitis (5 patients, 33.3%). Previous ocular surgery was found in 7 patients (46.6%). Previous extraocular tuberculosis (TB) infection or previous TB contact was detected in 11 patients (73.3%). No radiologic findings of active extraocular TB were detected. ATT was used in 15 patients, sometimes with the addition of systemic corticosteroids (5 patients) and methotrexate (1 patient); 14 patients achieved complete remission (93.3%). CONCLUSION: Presumed TB-related scleritis may appear in recurrent scleritis of unknown origin and positive QFT. It may occur after prior uveitis and/or concomitantly with uveitis or peripheral keratitis, and it may be triggered by previous ocular surgery. No patients had evidence of concurrent active extraocular infection, although many had previous TB infection or TB contact. ATT was effective, sometimes with the addition of systemic corticosteroids and methotrexate.

RESUMO

OBJECTIVE: To describe a retrospective review of HIV patients with noninfectious uveitis. Data collected included: demographics, anatomic classification and phenotypic diagnosis of the uveitis, systemic immune-mediated disorders (IMD), time from HIV diagnosis to uveitis, CD4 count, viral load, treatment and complications of treatment and time of follow-up. RESULTS: Twenty patients (18 males) were included. The time lag between HIV diagnosis and the onset of uveitis was 9 ± 8.5 years. Mean CD4 count was 670 ± 294 cells/ml. Viral load was undetectable in 14 out of 18 cases. In 6 patients IMD was diagnosed prior to or concurring with the uveitis diagnosis. The use of immunosuppressive therapies was necessary in 6 patients (including biologics in 4 cases). The mean follow-up was 42.2 months. CONCLUSIONS: noninfectious uveitis could be the first manifestation of IMD in patients with well-controlled HIV infection. Immunosuppression appeared to be a safe therapeutic option in our cohort of patients.

RESUMO

OBJECTIVES: To evaluate effectiveness and safety of certolizumab pegol (CZP) in uveitis due to immune-mediated inflammatory diseases (IMID). METHODS: Multicentre study of CZP-treated patients with IMID uveitis refractory to conventional immunosuppressant. Effectiveness was assessed through the following ocular parameters: best-corrected visual acuity, anterior chamber cells, vitritis, macular thickness and retinal vasculitis. These variables were compared between the baseline, and first week, first, third, sixth months, first and second year. RESULTS: We studied 80 (33 men/47 women) patients (111 affected eyes) with a mean age of 41.6±11.7 years. The IMID included were: spondyloarthritis (n=43), Behçet's disease (n=10), psoriatic arthritis (n=8), Crohn's disease (n=4), sarcoidosis (n=2), juvenile idiopathic arthritis (n=1), reactive arthritis (n=1), rheumatoid arthritis (n=1), relapsing polychondritis (n=1), CONCLUSIONS: CZP seems to be effective and safe in uveitis related to different IMID, even in patients refractory to previous biological drugs.

RESUMO

Purpose: To assess the efficacy and safety of adalimumab in elderly patients with noninfectious uveitis (NIU).Methods: An observational, retrospective, multicenter study was done. Changes in best-corrected visual acuity (BCVA), inflammatory activity parameters, central retinal thickness (CRT), and the occurrence of adverse events (AE) developed during follow-up were recorded.Results: A total of 82 eyes from 41 patients 60 years of age and older with noninfectious uveitis treated with adalimumab were included. A significant improvement in BCVA (71.5 to 75.4 letters, p = .001) and in CRT (311.1 µm to 265 µm, p = .001) was observed. Moreover, a significant decrease from baseline in the rate of patients with anterior chamber cell (ACC) >0+ (34.6% to 5.7%, p = <0.001) or vitreous haze>0+ (21.3% to 4.3%, p = .002) was determined. AEs were observed in 11 patients (26.8%).Conclusion: Adalimumab can be safe and efficacious for the treatment of NIU in patients 60 years of age and older.

RESUMO

Acute macular neuroretinopathy (AMN) is a rare disease, the etiology of which remains unclear. An ischemic event at the level of the deep capillary plexus has been proposed. The authors present three cases of AMN in the context of active systemic Behçet's disease, with the support of multimodal imaging. All patients were known to have Behçet's disease before the diagnosis of AMN. AMN was confirmed in all three cases on spectral domain optical coherence tomography (SD-OCT), near infrared reflectance and OCT angiography. Behçet's disease is known to be a prothrombotic disease. The presentation of AMN in this context supports the presumed ischemic etiology of AMN. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:634-638.].
