Referrals for rheumatologic evaluation following a positive antinuclear antibody test result. A cross-sectional single center Brazilian study.

Background: In general, patients are referred for rheumatological evaluation due to isolated laboratory abnormalities, especially antinuclear antibody (ANA) positivity, with the risk of more severe patients remaining on the waiting list for longer than desired. The aim of this study was to analyze the demographic, clinical, and laboratory information of patients referred to a specialized rheumatological care unit because of positive antinuclear antibody.

Methods: This is a retrospective study of 99 out of 1670 patients seen by the same rheumatologist between 01/01/2011 and 01/01/2019.

HLA Alleles in a Behçet Disease Multiethnic Population With and Without Ophthalmic Manifestations.

Objective: The aim of this study was to analyze HLA alleles in patients with Behçet disease (BD) and their correlation with ophthalmic manifestations (OMs) in a multiethnic Brazilian population.

Methods: This case-control study compared 72 BD patients with or without OM who underwent a thorough ophthalmologic evaluation, including best-corrected visual acuity, bino-ophthalmoscopy, and HLA analysis, with 144 matched healthy controls. Fluorescein angiography was also performed in the patients with BD and OM.

Epidemiologic Features of Systemic Vasculitides in the Southeast Region of Brazil: Hospital-Based Survey.

Background/objective: The epidemiology of vasculitis is variable in different geographic areas, and this issue has not been approached in Brazil yet. The objective of this study was to assess the frequency of vasculitis in specialized centers in Brazil.

Methods: This cross-sectional study was performed in 9 vasculitis outpatient clinics from 6 different states mainly from the Southeast and the Northeast regions of Brazil between 2015 and 2017.

Recommendations of the Brazilian Society of Rheumatology for the induction therapy of ANCA-associated vasculitis.

The purpose of these recommendations is to guide the appropriate induction treatment of antineutrophil cytoplasmic antibody-associated vasculitis (AAV) patients with active disease. The recommendations proposed by the Vasculopathies Committee of the Brazilian Society Rheumatology for induction therapy of AAV, including granulomatosis with polyangiitis, microscopic polyangiitis and renal-limited vasculitis, were based on systematic literature review and expert opinion. Literature review was performed using Medline (PubMed), EMBASE and Cochrane database to retrieve articles until October 2016.

Ocular involvement in patients with spondyloarthritis.

Ocular inflammatory diseases can present as isolated conditions but also as part of systemic inflammatory diseases. Anterior uveitis is closely related to SpA and shares the common genetic background of HLA-B27. Other ocular manifestations, such as episcleritis and scleritis, may also occur, although less frequently.

Giant cell arteritis: a multicenter observational study in Brazil.

Objective: To describe demographic features, disease manifestations and therapy in patients with giant cell arteritis from referral centers in Brazil.

Methods: A retrospective cohort study was performed on 45 giant cell arteritis patients from three university hospitals in Brazil. Diagnoses were based on the American College of Rheumatology classification criteria for giant cell arteritis or temporal artery biopsy findings.
