Symposium ArticleEpidemiology of Spondyloarthritis in Brazil
Section snippets
METHODS
During the period 2006 to 2007, 28 university centers in Brazil used a standardized protocol of investigation to study epidemiological, clinical and radiological variables of 1036 consecutive patient with SpA. This protocol was previously designed by the Spanish Registry of Spondyloarthritis and was also used by approximately 100 centers in 10 other Iberoamerican countries, which constituted the RESPONDIA Group. The general methodology and data analysis was previously pub- lished.8 Validated
RESULTS
The study included 1036 patients, with the diagnosis of AS (72.3%), PsA (13.7%), USpA (6.3%), reactive arthritis (3.6%), juvenile SpA (3.1%) and arthritis related to inflammatory bowel disease (1.0%). There was predominance of male patients (73.6%). With regard to ethnicity, 59.5% were white, 25.9% were African-Brazilians (5.2% pure black and 20.7% Mulattos) and 14.6% were from other origins (mixture of white, black, indigenous and/or East Asians). The mean age was 43.7 ± 12.6 years, and the
DISCUSSION
This is the first epidemiologic study analyzing patients with SpA from all 5 geographic regions in Brazil. The common protocol of investigation was important because it enabled different SpA outpatient clinics around the country to use the same instruments to assess their patients.
AS was the most frequent disease observed in the Brazilian series, affecting 72.3% of the patients. Because some patients with psoriatic arthritis plus oligoarticular disease are treated by dermatologists, some

The epidemiology of psoriatic arthritis: A literature review
2021, Best Practice and Research: Clinical RheumatologyCitation Excerpt :In this study, SpA was defined based on the European Spondyloarthropathy Study Group (ESSG) criteria and subtypes were based on physician diagnosis [50]. However, in a similar study from Brazil of 1036 patients with SpA using the RESPONDIA protocol, AS was the most common subtype (72.3%), followed by PsA (13.7%) [51]. A nationwide telephone survey in France also found that AS (48%) was the most prevalent form of SpA, followed by PsA (41%).

2011, American Journal of the Medical SciencesCitation Excerpt :With newer population-based instruments becoming available, the availability of the widely validated European Spondyloarthropathy Study Group criteria and the lower cost and greater feasibility of genetic testing, opportunities for true population-based studies of SpA are possible and will likely soon ensue. Brazil: Percival D. Sampaio-Barros, MD, PhD (Universidade de São Paulo, Brasil), reported results from a 2006–2007 study, in which 28 university centers in Brazil used a standardized protocol of investigation to study the epidemiologic, clinical and radiological variables of 1036 consecutive patients with the diagnosis of SpA.11 Patient diagnoses were predominantly AS (72%), followed by PsA (14%), undifferentiated SpA (6%), reactive arthritis (4%), juvenile SpA (3%) and arthritis related to IBD (1%).
