article 6 Citação(ões) na Scopus Anti-alpha-enolase antibodies in Behcet's disease: a marker of mucocutaneous and articular disease activity?(2018) PRADO, L. L.; GONCALVES, C. R.; VIANA, V. T.; SAAD, C. G. S.; BONFA, E.Objective. To assess IgM anti-alphaenolase antibodies (AAEA) in systemic Behget's disease (BD) and its possible association with clinical manifestations and disease activity. Methods. Ninety-seven consecutively selected BD patients were compared to 36 enteropathic spondyloarthritis (ESpA) [24 Crohn's disease (CD) and 12 ulcerative colitis (UC)] patients and 87 healthy controls. 1gM AAEA was detected by immunoblotting. Disease activity was assessed by standardised indexes, Brazilian BD Current Activity Form (BR-BDCAF) for BD and HarveyBradshaw Index (HBI) for CD and UC patients. A second evaluation was performed in BD patients (n=56), regarding IgM AAEA presence, disease activity scores and C-reactive protein (CRP). Results. Higher IgM AAEA prevalence was found in 97 BD (17.7%) compared to ESpA (2.8%) and healthy controls (2.3%), p< O. O01. IgM AAEA frequency was higher in active BD compared to inactive BD (30.2% vs. 7.4%, p=O. O06), a finding confirmed in the second cross-sectional evaluation of 56 of these BD patients (45.5% vs. 13.3%, p=O. 02). Mean BR-BDCAF scores were higher in IgM AAEA positive group on both evaluations (9.1 + 5.4 vs. 4.9 + 4.9, p=O. O02; 5.0 + 4.9 vs. 2.2 + 2.9, p=O. 01, respectively). BD patients with mucocutaneous and articular symptoms presented higher IgM AAEA positivity in the first and second evaluations (64.7% vs. 27.5%, p=O. O05; 36.4% vs. 7.1%, p=0.039 respectively). Conclusions. Our data support the notion that alpha-enolase is a target antigen in BD, particularly associated with disease activity, mucocutaneous and articular involvement. In addition, IgM AAEA may distinguish BD from ESpA, especially in patients with high disease activity.conferenceObject CLINICAL OUTCOMES OF PATIENTS WITH TAKAYASU ARTERITIS ON TNF A INHIBITORS: RESPONSE TO TREATMENT AND LATENT TUBERCULOSIS INFECTION IN FOLLOW-UP FOR 24 MONTHS(2019) RIBEIRO, Surian; ORTEGA, Mariana; PRADO, Leandro; SHINJO, Samuel; PEREIRA, Rosa- OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY BIOMARKERS AND MICROPERIMETRY FEATURES IN BEHÇET'S UVEITIS(2023) FERREIRA, Bruno F. A.; HIGASHI, Alex H.; PRADO, Leandro L.; GONCALVES, Celio R.; HADDAD, Maria A. O.; ZACHARIAS, Leandro C.; HIRATA, Carlos E.; YAMAMOTO, Joyce H.Purpose: To evaluate the parafoveal macular microvasculature and the macular function in patients with retinal vasculitis associated with Beh & ccedil;et's uveitis.Methods: In 14 patients with inactive Beh & ccedil;et's uveitis and 26 control individuals (13 with nonocular Beh & ccedil;et's syndrome and 13 healthy subjects), we analyzed the retinal nerve fiber layer, ganglion cell layer, full retinal thickness, foveal avascular zone area and sectorial parafoveal vascular density in the superficial vascular plexus, intermediate capillary plexus, and deep capillary plexus using SPECTRALIS optical coherence tomography (OCT) 2 and OCT angiography. Macular sensitivity was analyzed using an MP-3 microperimeter.Results: Eighteen eyes (78%) had a best-corrected visual acuity >= 20/25. Significant differences were found in Beh & ccedil;et's uveitis in comparison with the controls on the OCT and OCT angiography: 14.8%, 22.4%, and 14.9% ganglion cell layer thinning in the global, nasal, and inferior sectors, respectively; 6%, 13.2%, and 7.5% full retinal thickness thinning in the superior, nasal, and inferior sectors; and 16.8%, 14.9%, 23.6%, 15.8%, and 12.6% mean deep capillary plexus density reduction in the global, superior, nasal, inferior, and temporal sectors. Microperimetry data demonstrated significant mean reductions of 21% and 23.6% in central and average macular sensitivities and 28.8%, 40.4%, 27.7%, and 24.2% in the superior, nasal, inferior, and temporal sectors, respectively. Outer plexiform layer elevations were observed in Beh & ccedil;et's uveitis (69.6%).Conclusion: Beh & ccedil;et's uveitis presented structural and functional macular damage despite good best-corrected visual acuity, mainly affecting the nasal sector and the deep capillary plexus. On OCT and OCT angiography, quantitative and qualitative changes can be valuable biomarkers of ocular involvement in Beh & ccedil;et's syndrome.
