[Evaluation of performance of BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) in a Brazilian cohort of 1,492 patients with spondyloarthritis: data from the Brazilian Registry of Spondyloarthritides (RBE)].

Objective: To analyze the results of the application of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) in a large series of Brazilian patients with the diagnosis of SpA and establish its correlations with specific variables into the group.

Methods: A common protocol of investigation was prospectively applied to 1492 Brazilian patients classified as SpA according to the European Spondyoarthropathies Study Group (ESSG), attended at 29 referral centers of Rheumatology in Brazil. Clinical and demographic variables, and disease indices (BASDAI, Basfi, Basri, Mases, ASQol) were applicated.

[Epidemiologic profile of juvenile-onset compared to adult-onset spondyloarthritis in a large Brazilian cohort].

Objective: To analyze the clinical and epidemiologic characteristics of juvenile-onset spondyloarthritis (SpA) (< 16 years) and compare them with a group of adult-onset (≥ 16 years) SpA patients.

Patients And Methods: Prospective, observational and multicentric cohort with 1,424 patients with the diagnosis of SpA according to the European Spondyloarthropathy Study Group (ESSG) submitted to a common protocol of investigation and recruited in 29 reference centers participants of the Brazilian Registry of Spondyloarthritis (RBE - Registro Brasileiro de Espondiloartrites). Patients were divided in two groups: age at onset<16 years (JOSpA group) and age at onset ≥ 16 years (AOSpA group).

Assessment of fatigue in a large series of 1492 Brazilian patients with Spondyloarthritis.

Background: The aim of the present study was to analyze the score of fatigue in a large cohort of Brazilian patients with SpA, comparing different disease patterns and its association with demographic and disease-specific variables.

Methods: A common protocol of investigation was prospectively applied to 1492 Brazilian patients classified as SpA according to the European Spondyloarthropathies Study Group (ESSG) criteria, attended at 29 reference centers. Clinical and demographic variables were recorded.

Profile of the use of disease modifying drugs in the Brazilian Registry of Spondyloarthritides.

Introduction: Few studies have evaluated the profile of use of disease modifying drugs (DMD) in Brazilian patients with spondyloarthritis (SpA).

Methods: A common research protocol was applied prospectively in 1505 patients classified as SpA by criteria of the European Spondyloarthropathies Study Group (ESSG), followed at 29 referral centers in Rheumatology in Brazil. Demographic and clinical variables were obtained and evaluated, by analyzing their correlation with the use of DMDs methotrexate (MTX) and sulfasalazine (SSZ).

Enteropathic arthritis in Brazil: data from the Brazilian Registry of Spondyloarthritis.

Unlabelled: Inflammatory bowel diseases (Crohn's disease and ulcerative rectocolitis) have extraintestinal manifestations 25% of the patients, with the most common one being the enteropathic arthritis.

Methods: Prospective, observational, multicenter study with patients from 29 reference centers participating in the Brazilian Registry of Spondyloarthritis (RBE), which incorporates the RESPONDIA (Ibero-American Registry of Spondyloarthritis) group. Demographic and clinical data were collected from 1472 patients and standardized questionnaires for the assessment of axial mobility, quality of life, enthesitic involvement, disease activity and functional capacity were applied.

Effect of enthesitis on 1505 Brazilian patients with spondyloarthritis.

Objective: To analyze the clinical effect of enthesitis in a large Brazilian cohort of patients with spondyloarthritis (SpA).

Methods: A common protocol of investigation was prospectively applied to 1505 patients with SpA in 29 centers in Brazil. Clinical and demographic variables and disease indexes were investigated.

Low prevalence of renal, cardiac, pulmonary, and neurological extra-articular clinical manifestations in spondyloarthritis: analysis of the Brazilian Registry of Spondyloarthritis.

Objective: To describe the extra-articular manifestations (cardiac, renal, pulmonary, and neurological), usually not related to spondyloarthritis (SpA), in a large cohort of Brazilian patients.

Materials And Methods: This retrospective study analyzed 1,472 patients diagnosed with SpA and cared for at 29 health care centers distributed in the five major geographic regions in the country, participating in the Brazilian Registry of Spondyloarthritis (BRS). All patients were assessed for the prevalence of major extra-articular manifestations (cardiac, renal, pulmonary, and neurological), classified according to the diagnosis [ankylosing spondylitis (AS), psoriatic arthritis (PsA), reactive arthritis (ReA), arthritis associated with inflammatory bowel disease (IBD), undifferentiated spondyloarthritis (uSpA), and juvenile SpA], and according to the clinical presentation (axial, peripheral, mixed, and enthesitis).

Gender characterization in a large series of Brazilian patients with spondyloarthritis.

An increasing number of women have been diagnosed with spondyloarthritis (SpA) in recent decades. While a few studies have analyzed gender as a prognostic factor of the disease, no studies have addressed this matter with a large number of patients in South America, which is a peculiar region due to its genetic heterogeneity. The aim of the present study was to analyze the influence of gender on disease patterns in a large cohort of Brazilian patients with SpA.

Ethnic influence in clinical and functional measures of Brazilian patients with spondyloarthritis.

Objective: Spondyloarthritides (SpA) can present different disease spectra according to ethnic background. The Brazilian Registry of Spondyloarthritis (RBE) is a nationwide registry that comprises a large databank on clinical, functional, and treatment data on Brazilian patients with SpA. The aim of our study was to analyze the influence of ethnic background in SpA disease patterns in a large series of Brazilian patients.

Pyomyositis associated with diabetes mellitus and liver cirrhosis.

Pyomyositis is a primary infection of the skeletal muscle, occurring most commonly in tropical countries. Adults who develop the disease have, in most cases, associated comorbidities that compromise the immune system, including diabetes mellitus and liver cirrhosis.
